As shown in FIG. 6, the rear side of the pot body 201 is formed with a spout 212, and the front side is formed with a handle 211.

The water storage apparatus 100 of the embodiment of the present invention further includes: a float seat 203 and a float 204. The float seat 203 is fixed with the kettle body 201 or the cover body 202, and a water passing port 231 for water in the kettle body 201 to pass in and out is arranged on the float seat 203. The float 204 is vertically movably disposed in the float seat 203. By providing the float seat 203 and the float 204 in the kettle 200, the water level inside the kettle 200 can be indicated based on the position of the float 204.

The float seat 203 may be fixed to the kettle body 201 or to the cover 202. In some embodiments, the float seat 203 is fixed to the cover 202, and the fixing structure is simpler and more suitable for the use habit of the user. As shown in fig. 13, the cover 202 includes a cover body 221 and a cover sidewall 222, and a plurality of fixing pins 2211 are formed to extend downward on the lower surface of the cover body 221; a plurality of seat fixing holes 232 are formed on the float seat 203 at positions corresponding to the plurality of fixing bolts 2211; the fixing bolt 2211 is inserted into the seat fixing hole 232 and then heated and softened to form a cap structure to fix the float seat 203 and the cover 202. The cover 202 can be made of a PP material, and when the cover is assembled, the fixing bolt 2211 on the cover 202 is inserted into the seat fixing hole 232 of the float seat 203, the tail end of the fixing bolt 2211 extends out of the seat fixing hole 232, and the fixing bolt is heated and softened by using equipment such as a soldering iron and is stressed to form a fixing cap type structure, so that the float seat 203 and the seat fixing hole 232 are fixed firmly, the connection belongs to permanent connection and is not detachable after connection.

As shown in fig. 5 and 14, in some embodiments, the float 204 of the water storage device 100 of embodiments of the present invention comprises: a float body 241, a float cover 242 and a magnetic member 243, wherein the float cover 242 is disposed above the float body 241 and defines a cavity 244 with the float body 241, and the magnetic member 243 is disposed within the float cover 242. The magnetic member 243 may be a magnet, for example. The magnetic member 243 is disposed at the top of the float 204, so that the magnetic member 243 and the magnetic resistor on the water level monitoring circuit board 305 in the device cover 300 can interact conveniently, and water level monitoring and water injection control of the water storage device 100 can be facilitated. The float cover 242 is connected with the float body 241 in a hot melting way; the magnetic member 243 is fixed in the float cover 242 by casting. In the injection molding, the magnetic member 243 is first placed in a mold of the float cover 242, and after the injection molding, the magnetic member 243 is embedded in the float cover 242, which is a non-detachable connection. Then, the float cover 242 and the float body 241 are connected by heat fusion, and after assembly, a sealed hollow structure is formed between the float cover 242 and the float body 241 to prevent water from entering.

As shown in fig. 12, the float seat 203 of the water storage device 100 according to the embodiment of the present invention includes a bottom wall 233 and a side wall 234, the bottom wall 233 and/or the side wall 234 is provided with a water passing opening 231, and the inner side surface of the side wall 234 is formed with a plurality of limiting ribs 235 at intervals; the float body 241 is sandwiched between the plurality of stopper ribs 235. In general, the bottom wall 233 and the side wall 234 of the float seat 203 are provided with a water gap 231 to ensure more accurate movement of the float 204. By forming a plurality of stopper ribs 235 at intervals on the inner surface of side wall portion 234, the vertical movement of float 204 in float seat 203 can be restricted, and float 204 can be prevented from deflecting.

In some embodiments, the water storage apparatus 100 of the present invention further includes: and a water level monitoring circuit board 305 disposed in the accommodating cavity 311. The water level monitoring circuit board 305 is provided with a first magnetic resistor 351 and a second magnetic resistor 352, and the first magnetic resistor 351 and the second magnetic resistor 352 are different in the upper and lower positions and the front and rear positions on the water level monitoring circuit board 305, so that the state of the kettle 200 is indicated based on the interaction of the first magnetic resistor 351, the second magnetic resistor 352 and the magnetic member 243. The states of the water jug 200 may include a water level state, a position state, an in-out state. The water level state of the water jug 200 may include a non-filling state and a filling required state, and the position state of the water jug 200 may include a put-in-place state and an not-put-in-place state. The entry and exit states of the jug 200 may include the jug 200 being put in and the jug 200 being removed.

As shown in fig. 14, in some embodiments, the water jug 200 is configured to be placed from the front to the rear under the device cover 300. The water level monitoring circuit board 305 is disposed above the magnetic member 243 in the front-rear direction, the projection of the first magnetoresistor 351 on the vertical plane is located below the projection of the second magnetoresistor 352, and the projection of the first magnetoresistor 351 on the horizontal plane is located behind the projection of the second magnetoresistor 352. When the water kettle 200 has different water level states, different position states and different access states, the interaction of the first magnetic resistor 351, the second magnetic resistor 352 and the magnetic member 243 is obviously different, that is, whether the first magnetic resistor 351 and the second magnetic resistor 352 have signals or not, the sequence of the signals of the first magnetic resistor 351 and the second magnetic resistor 352 and the like are different, so that the water level state, the position state and the access state of the water kettle 200 can be indicated based on the interaction of the first magnetic resistor 351, the second magnetic resistor 352 and the magnetic member 243.

Specifically, the following conditions are satisfied among the magnetic member 243, the first magnetoresistor 351, and the second magnetoresistor 352:

v≤r；

u+v＞r；

u+v-w≤r；

where r is the effective working radius of the magnetic member 243; v is the farthest up-down distance between the first magnetoresistor 351 and the magnetic member 243; u is an up-down distance between the first and second magnetoresistors 351 and 352; w is the movable distance of the magnetic member 243 up and down in the water jug 200. The farthest distance v between the first magnetic sensor 351 and the magnetic member 243 is not greater than r, so that the first magnetic sensor 351 can sense the magnetic force of the magnetic member 243 to send a signal when the water bottle 200 is correctly placed under the device cover 300. When the first magnetic resistor 351 has no signal, it indicates that the kettle 200 is not in place. The non-seated state of the water jug 200 includes two cases, one is that the water jug 200 is not seated under the device cover 300, for example, the water jug 200 is seated in other storage compartments of the refrigerator 400 or moved out of the refrigerator 400; the other is that the water jug 200 is not placed completely in place although it is placed under the device cover 300.

The distance limit condition between the effective acting radius of the magnetic member 243 and the first and second magnetoresistors 351 and 352 can realize the monitoring of the liquid level in the kettle 200: when the floater 204 is not supported by the water in the kettle 200, u + v is larger than r, the second magnetic sensing resistor 352 cannot sense the magnetic force of the magnetic part 243, no signal is generated, and water needs to be injected when the liquid level is too low; when the water in the kettle 200 lifts the floater 204, u + v-w is less than or equal to r, the second magnetic sensing resistor 352 can sense the magnetic force of the magnetic part 243, and a signal is generated, which indicates that water injection is not needed.

The magnetic force of the magnetic member 243 is related to the type of the magnetic member 243. As described above, the magnetic member 243 may be a magnet. The effective magnetic acting radius r of the magnets with different specifications is different. In general, in consideration of cost, the water storage apparatus 100 according to the embodiment of the present invention uses a magnet having an effective acting radius r of magnetic force of 20mm or less as the magnetic member 243.

The projection of the first magneto-resistor 351 on the horizontal plane is behind the projection of the second magneto-resistor 352, that is, there is a front-to-back distance between the first magneto-resistor 351 and the second magneto-resistor 352. Therefore, whether the water bottle 200 is put in or taken out can be judged by the front and back sequence of the signals of the first magnetic resistor 351 and the second magnetic resistor 352. The front-back distance m between the first magneto-resistor 351 and the second magneto-resistor 352 is generally equal to or greater than 10 mm. For example, if the water kettle 200 is filled with water, when the second magnetic resistor 352 has a signal first and the first magnetic resistor 351 has a signal later, the water kettle 200 is put in; when the first magnetic sensor 351 has no signal first and the second magnetic sensor 352 has no signal later, the kettle 200 is removed.

As shown in fig. 9 and 10, a plurality of fixing blocks 361 are formed on the circuit board base 306 at intervals along the front-rear direction, bayonets 3611 are respectively formed on the plurality of fixing blocks 361, and the water level monitoring circuit board 305 is inserted into the bayonets 3611. Meanwhile, a plurality of hooks 362 are formed on the circuit board base 306 in a manner of extending upwards at positions close to the fixed blocks 361, and the water level monitoring circuit board 305 is clamped between the hooks 362 and the circuit board base 306. By inserting the water level monitoring circuit board 305 into the bayonet 3611 and fixing the water level monitoring circuit board with the hook 362, the water level monitoring circuit board 305 can be stably fixed.

As shown in fig. 6, the water level monitoring circuit board 305 is a special-shaped board, and the lower end of the portion where the second magnetic resistor 352 is disposed is higher than the lower end of the portion where the first magnetic resistor 351 is disposed. A convex portion 365 is formed on the circuit board base 306, and a portion of the water level monitor circuit board 305 where the second magnetic resistor 352 is provided is overlapped on the convex portion 365 of the circuit board base 306. By forming the convex portion 365 on the circuit board base 306, the portion of the water level monitoring circuit board 305 on which the second magnetic resistor 352 is disposed is overlapped on the convex portion 365 on the circuit board base 306, so that the water level monitoring circuit board 305 can be more stably fixed on the circuit board base 306.

The projection of the left and right width of the convex part 365 of the circuit board base 306 on the horizontal plane covers the handle 211 of the kettle body 201. A projection 2212 is formed on the cover main body 221 of the cover 202 corresponding to the projection 365 of the circuit board base 306, and the tip of the projection 2212 of the cover 202 covers the upper end of the handle 211. The lower portion of the front sidewall of the main body 301 of the device cover 300 has a docking port 312 at a position corresponding to the handle 211. The front end of the convex portion 2212 of the cover body 202 covers the upper end of the handle 211, and the device cover 300 is provided with the butt joint port 312, so that the matching between the kettle 200 and the device cover 300 can be further limited, and a user can place the kettle 200 in place quickly and accurately.

In some embodiments, the water storage apparatus 100 of the embodiment of the present invention may further include: an electric switching device 901 and a control device 900. The electric opening/closing device 901 opens and closes the water passage of the water inlet pipe 304. The control device 900 is connected to the water level monitoring circuit board 305 and the electric switch device 901, and is configured to control the operation of the electric switch device 901 based on the signal states of the first magnetic resistor 351 and the second magnetic resistor 352. By arranging the electric switch device 901 and the control device 900, the water storage device 100 of the embodiment of the invention can realize intelligent control of water level monitoring and automatic water injection, and meet the requirements of more convenient and intelligent domestic water of users.

The water storage device 100 of the embodiment of the invention can be further provided with a reminding device 902 for sending displacement reminding when the water kettle 200 is not placed in place. The reminder 902 may be integrated within the device cover 300. The control device 900 is connected to the reminding device 902 and is used for controlling the reminding device 902 to send out displacement reminding when the first magnetic resistor 351 is not in signal. The reminder may be, for example, a beep or the like.

Fig. 16 is a control flowchart of the water storage apparatus 100 shown in fig. 2 in which the water bottle 200 is placed in the inner container 402. After the water bottle 200 is placed in the refrigerator 400, the method for controlling the water storage device 100 according to the embodiment of the present invention includes:

s102: judging whether the first magnetoresistor 351 has a signal; if yes, go to step S104; if not, go to step S110.

S104: judging whether the second magnetic resistor 352 has a signal; if yes, go to step S106; if not, go to step S108.

S106: the electric switch 901 is controlled to be closed, and water is not filled into the kettle 200.

S108: the electric switch device 901 is controlled to be turned on, and water is filled into the kettle 200.

S110: the reminder device 902 is controlled to issue a shift reminder.

After the water jug 200 is placed in the refrigerator 400, it is first judged whether the water jug 200 is placed in place. Since the first magnetoresistor 351 has a signal after the kettle 200 is put in place, whether the kettle 200 is put in place can be determined by judging whether the first magnetoresistor 351 has a signal. Therefore, when the first magnetic resistor 351 has no signal, which indicates that the water bottle 200 is not accurately placed below the device cover 300, the reminding device 902 is controlled to send out displacement reminding at the moment. When the first magnetic resistor 351 has a signal indicating that the water bottle 200 is in place, it is determined whether water needs to be filled into the water bottle 200. Here, in order to simplify the control process of water filling, it may be set that water is considered to be filled in the water bottle 200 when the float 204 is lifted by water, and water filling is not required. That is, when the second magnetic resistor 352 has a signal, it is determined that the water inside the kettle 200 is filled with water, and the water is not required to be filled. Therefore, when the second magnetic resistor 352 has a signal, the electric switch device 901 is controlled to be closed, and water is not filled into the kettle 200. When the second magnetic resistor 352 has no signal, the electric switch device 901 is controlled to be turned on, and water is filled into the kettle 200 until the second magnetic resistor 352 has a signal.

The water storage apparatus 100 of the embodiment of the present invention further includes: a signal processing circuit board 307. The signal processing circuit board 307 is disposed in the accommodating cavity 311, connected to the water level monitoring circuit board 305 and the control device 900, and configured to receive and process the signal output by the water level monitoring circuit board 305, and then send the processed signal to the control device 900.

A plurality of fixing posts 363 are further formed on the circuit board base 306, first fixing holes 3631 are formed on the fixing posts 363, and/or inserting rods 3632 are formed on the fixing posts 363. A second fixing hole 371 is formed at a position on the signal processing circuit board 307 corresponding to the fixing post 363, and the fixing of the signal processing circuit board 307 and the circuit board base 306 is achieved by inserting the fixing member 308 through the second fixing hole 371 and/or inserting the inserting rod 3632 into the second fixing hole 371. As shown in fig. 6, four fixing posts 363 are formed on the circuit board base 306, first fixing holes 3631 are formed on the two fixing posts 363, inserting rods 3632 are formed on the two fixing posts 363, the first fixing holes 3631 and the inserting rods 3632 are arranged diagonally, the inserting rods 3632 are used for positioning when the signal processing circuit board 307 is installed, and the first fixing holes 3631 are used for being connected with the second fixing holes 371 to fix the signal processing circuit board 307.

In some embodiments, the signal processing circuit board 307 is configured to receive the signal status of the first and second magnetoresistors 351, 352 of the water level monitoring circuit board 305 and generate kettle status information. The control device 900 is used to control the operation of the electric switch device 901 based on the pot status information. The pot state information may be determined by a preset mapping relationship, where the mapping relationship specifies pot state information corresponding to the signal state of the first magneto-resistor 351, the signal state of the second magneto-resistor 352, and the signal order of the first magneto-resistor 351 and the second magneto-resistor 352. For example, in the mapping relation, it is specified that the pot state information corresponding to "the first magnetoresistor 351 has a signal and the second magnetoresistor 352 has no signal" is "water injection required". For example, the mapping relation specifies that "the first magnetoresistor 351 has a signal before and the second magnetoresistor 352 has a signal after" and the corresponding pot state information is "water is filled". For another example, it is specified in the mapping that "the first magneto resistor 351 has no signal first, and the second magneto resistor 352 has no signal later", and the corresponding pot status information is "the pot 200 has been removed".

As shown in fig. 15, the signal processing circuit board 307 may be powered by the control device 900 (which may be a main control board of the refrigerator 400), and a signal transmission line is provided between the two; the water level monitoring circuit board 305 is powered by the signal processing circuit board 307, and a signal transmission line is arranged between the water level monitoring circuit board 305 and the signal processing circuit board 307; the open and closed states of the electric switching device 901 (e.g., solenoid valve) are controlled by the control device 900 in accordance with the signal received from the signal processing circuit board 307; the reminder 902 is controlled by the control device 900 according to the signal received from the signal processing circuit board 307.

Several states and control examples of the water storage apparatus 100 according to the embodiment of the present invention are described below:

1) when the water bottle 200 is not placed under the device cover 300, the first and second magnetoresistors 351 and 352 cannot sense the magnetic force of the magnetic member 243, and no signal is output from the first and second magnetoresistors 351 and 352. The electrical switching apparatus 901 remains off.

2) When there is no water in the water bottle 200 or the water level is not high, the float 204 is not lifted by the water, and when the water bottle 200 is placed under the device cover 300, the first magnetic sensor 351 is in the magnetic range and can sense the magnetic force of the magnetic member 243, but the second magnetic sensor 352 is not in the magnetic range and cannot sense the magnetic force of the magnetic member 243, that is, the first magnetic sensor 351 has a signal, but the second magnetic sensor 352 has no signal. The signal processing circuit board 307 receives the signal "the first magnetic sensor 351 has a signal, the second magnetic sensor 352 has no signal" output from the water level monitoring circuit board 305, and the kettle state information is "water needs to be filled". The signal processing circuit board 307 sends the kettle status information to the control device 900, and the control device 900 controls the electric switch device 901 to be turned on to inject water into the kettle 200.

When the water kettle 200 is filled with water, the floater 204 is lifted by the water, and at the moment, the first magnetic resistor 351 and the second magnetic resistor 352 are both in the magnetic range, so that both the first magnetic resistor and the second magnetic resistor can sense magnetic force and have signals. The signal processing circuit board 307 receives the signal "the first magnetic sensor 351 is a signal, and the second magnetic sensor 352 is a signal" outputted from the water level monitoring circuit board 305, and the kettle state information is "water is filled". The signal processing circuit board 307 sends the kettle status information to the control device 900, and the control device 900 controls the electric switch device 901 to close to stop the water injection into the kettle 200.

3) When the water bottle 200 is removed in a full water state, the first magnetic sensor 351 cannot sense the magnetic force first, and then the second magnetic sensor 352 cannot sense the magnetic force. The signal processing circuit board 307 receives the signal "no signal is first generated at the first magneto resistor 351 and no signal is generated at the second magneto resistor 352" outputted from the water level monitoring circuit board 305, and the kettle state information is "the kettle 200 is moved out". The signal processing circuit board 307 does not send a signal to the control device 900, and the electrical switching device 901 remains off.

4) When the water kettle 200 is taken away after being filled with water, the floater 204 is not lifted by the water, the first magnetic sensing resistor 351 cannot sense the magnetic force at first and becomes no signal, and the second magnetic sensing resistor 352 cannot sense the magnetic force all the time. The signal processing circuit board 307 receives the signal "no signal of the first magnetic sensor 351 and no signal of the second magnetic sensor 352" output from the water level monitoring circuit board 305, and the corresponding kettle state information is "the kettle 200 has been moved out". The signal processing circuit board 307 does not send a signal to the control device 900, and the electrical switching device 901 remains off.

5) When the water bottle 200 is placed under the set cover 300 in a full water state, the second magnetic resistor 352 senses the magnetic force first, and then the first magnetic resistor 351 senses the magnetic force again. The signal processing circuit board 307 receives the signal "the second magnetic sensor 352 has a signal first and the first magnetic sensor 351 has a signal later" output from the water level monitoring circuit board 305, and the corresponding kettle state information is "the kettle 200 is filled with water". The signal processing circuit board 307 does not send a signal to the control device 900, and the electrical switching device 901 remains off.

6) When the water bottle 200 is filled with water but the water bottle 200 is not placed in place, the second magnetic sensor 352 senses the magnetic force, but the first magnetic sensor 351 does not sense the magnetic force. The signal processing circuit board 307 receives the signal "there is a signal in the second magnetic sensor 352 and no signal in the first magnetic sensor 351" output from the water level monitoring circuit board 305, and the corresponding kettle state information is "the kettle 200 is filled with water, but the placing position is incorrect". The signal processing circuit board 307 does not send a signal to the control device 900, and the electrical switching device 901 remains off. The signal processing circuit board 307 may also send the status signal to the control device 900, and the control device 900 controls the reminding device 902 to send out reminding information, such as a beep, etc., to remind the user to put the kettle 200 in place.

7) When the water bottle 200 is removed in a full state but not completely removed under the device cover 300, the first magnetic sensor 351 cannot sense the magnetic force, and the second magnetic sensor 352 can still sense the magnetic force. The signal processing circuit board 307 receives the signal "no signal of the first magneto resistor 351 and signal of the second magneto resistor 352" output from the water level monitoring circuit board 305, and the corresponding kettle state information is "the kettle 200 is full of water but is not completely moved out". The signal processing circuit board 307 does not send a signal to the control device 900, and the electrical switching device 901 remains off. Similarly, the signal processing circuit board 307 may also send the status signal to the control device 900, and the control device 900 controls the reminding device 902 to send out reminding information, such as a beep, etc., to remind the user to put the water bottle 200 in place or remove it completely.
