In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In one embodiment, an inclination angle detection device for electrical equipment is provided, which is suitable for detecting an inclination angle of electrical equipment with a water tank, where the electrical equipment may be specifically a dehumidifier, a humidifier, or the like.

The tilt detection device 110 is configured to monitor a tilt state of the electrical apparatus and send a detection signal to the detection circuit device 120, and the detection circuit device 120 is configured to calculate a tilt angle of the electrical apparatus according to the received detection signal.

The specific structure of the electrical equipment is different according to the type of the electrical equipment. Specifically, the tilt detection device 110 may be provided on a housing of the electrical equipment, or may be provided inside the electrical equipment. The tilt detection device 110 may specifically adopt a sliding resistance card, a tilt sensor, an acceleration sensor, or the like, and the tilt detection device 110 monitors the tilt state of the electrical equipment in real time, generates a corresponding detection signal, and sends the detection signal to the detection circuit device 120. The detection circuit device 120 performs analysis processing according to the received detection signal to obtain the tilt angle of the electrical equipment. It is understood that the specific manner in which the tilt angle is calculated by the detection circuitry 120 will vary depending on the type of tilt detection means 110. If the inclination detection device 110 adopts a sliding resistance card, the detection circuit device 120 calculates the inclination angle of the electrical equipment according to the resistance value change of the sliding resistance card; if the inclination detection device 110 employs an acceleration sensor, when the posture of the electrical equipment changes, the sensitive shaft of the acceleration sensor rotates a certain angle, and the acceleration on the sensitive shaft of the sensor changes due to the action of gravity, so that the change of the posture of the electrical equipment can be reflected by measuring the change of the acceleration, and the inclination angle can be obtained.

In one embodiment, as shown in FIG. 2, the tilt sensing device 110 includes a sliding resistive sheet coupled to a sensing circuit device 120. Specifically, the sliding resistance card can be vertically installed on a horizontal panel of the electrical equipment, and the horizontal panel refers to a panel parallel to the ground in the electrical equipment when the electrical equipment is normally placed on a horizontal ground.

Further, the tilt detection device 110 further includes a lever, an axial end of the sliding resistive sheet is fixed to one end of the lever, the other end of the lever is connected to the detection circuit device 120, and a contact of the sliding resistive sheet is connected to the detection circuit device 120. The sliding resistance piece is equivalent to a sliding resistor induced by gravity, the sliding resistance piece is vertically arranged on a horizontal panel of the electrical equipment, and when the electrical equipment is inclined, the sliding resistance piece slides, so that a contact point changes, and the resistance value of the sliding resistance piece also changes along with the change. The detection circuit device 120 may pre-store the corresponding relationship between the resistance value of the sliding resistance card and the inclination angle, and may directly obtain the inclination angle of the electrical equipment after detecting the actual resistance value of the sliding resistance card.

Correspondingly, in one embodiment, the detection circuitry 120 is a resistance detection circuit 122. The resistance value of the sliding resistive sheet is detected by the resistance detection circuit 122, so as to determine the inclination angle of the electrical equipment. The resistance detection circuit 122 does not have a unique resistance detection mode for the sliding resistance card, specifically, the sliding resistance card is connected with the resistance detection circuit 122 to form a closed loop, the resistance detection circuit 122 outputs direct current of rated voltage to the sliding resistance card, the resistance value of the sliding resistance card connected into the circuit can be calculated by detecting the current value in the circuit and combining the rated voltage, and therefore the inclination angle of the electrical equipment in the current state is determined according to the corresponding relation between the prestored resistance value and the inclination angle. The inclination state of the electrical equipment is monitored by using the sliding resistance card, the inclination angle of the electrical equipment is determined by detecting the resistance value of the sliding resistance card, and the device is simple, convenient and quick to operate and low in cost.

In one embodiment, as shown in FIG. 3, the detection circuitry 120 is also used to connect to a master controller 210 of the electrical device. The detection circuit device 120 also transmits the tilt angle of the electrical appliance to the main controller 210. After detecting the tilt angle of the electrical device, the detection circuit device 120 further sends the tilt angle to the main controller 210, so that the main controller 210 performs operations such as data display, storage, or subsequent data processing.

The tilt angle detection device of the electrical equipment monitors the tilt state of the electrical equipment by using the tilt detection device 110, and sends a corresponding detection signal to the detection circuit device 120, and the detection circuit device 120 calculates the tilt angle of the electrical equipment according to the received detection signal. Not only can detect whether electrical equipment inclines, but also can detect the inclination angle of electrical equipment to be convenient for judge the influence of inclination to electrical equipment, improved electrical equipment's safety in utilization.

In one embodiment, an electrical apparatus is provided, which is suitable for detecting an inclination angle of an electrical apparatus with a water tank, where the electrical apparatus may specifically be a dehumidifier, a humidifier, or the like. In this embodiment, the electrical device is a dehumidifier. As shown in fig. 3, the electrical apparatus includes a main controller 210, a power supply circuit 220 and the above-mentioned tilt angle detection device, and the main controller 210 is connected to the power supply circuit 220 and the detection circuit device 120. Further, in an embodiment, the electrical device further comprises an interaction means 230 connected to the main controller 210. The main controller 210 may be an MCU (Micro Control Unit), and the specific structure of the interaction device 230 is not unique, and may be a touch screen, an alarm lamp, or a speaker.

The electrical equipment uses the tilt detection device 110 to monitor the tilt state of the electrical equipment, and sends a corresponding detection signal to the detection circuit device 120, and the detection circuit device 120 calculates the tilt angle of the electrical equipment according to the received detection signal.

In one embodiment, the main controller 210 is further configured to send an inclination prompting instruction to the interaction device 230 when detecting that the inclination angle of the electrical equipment is smaller than the preset angle threshold, where the inclination prompting instruction is used to control the interaction device 230 to output a prompting message to remind the user that the road surface is uneven.

Specifically, the specific value of the preset angle threshold is not unique, and in this embodiment, the preset angle threshold is 90 degrees. When the inclination angle of the electrical equipment is smaller than 90 degrees, the electrical equipment can be considered to be in a slightly inclined state, and if the inclination angle of the electrical equipment reaches 90 degrees, the electrical equipment can be considered to be completely inclined. When the electrical equipment is in a slightly inclined state, the main controller 210 sends an inclination prompt instruction to the interaction device 230, and controls the interaction device 230 to output prompt information to remind a user that the road surface is uneven. Specifically, the interaction device 230 may display a preset text or a preset pattern, control a warning lamp to flash or a speaker to sound, or perform a combination of the above manners.

In this embodiment, when the electrical equipment is detected to be in a slightly inclined state, the main controller 210 controls the interaction device 230 to output prompt information to remind a user, so that the user can conveniently adjust the placement of the electrical equipment, normal operation of the electrical equipment due to inclination is prevented from being affected, and the use safety of the electrical equipment can also be improved.

Further, in an embodiment, the main controller 210 is further configured to perform full water detection on the water tank of the electrical equipment according to the inclination angle of the electrical equipment after receiving the release instruction corresponding to the prompt information input.

Specifically, the electric appliance may further include a water level detector disposed in the water tank, and the main controller 210 is connected to the water level detector. When the electrical equipment is not inclined, the main controller 210 receives the water level height data detected by the water level detector, compares the water level height data with the pre-stored water full threshold, and can also control the power supply circuit 220 to stop supplying power after the detected water level height reaches the water full threshold, and can also output water full prompt information through the interaction device 230 to remind a user to perform treatment, such as clearing water in the water tank or stopping filling the water tank.

After the electrical equipment is inclined, if the user thinks that the uneven road surface does not affect the operation of the equipment, the user can send a release instruction through the interaction device 230 to release the prompt of the uneven road surface, and then the main controller 210 performs full water detection on the water tank by combining the inclination angle. Specifically, main controller 210 utilizes the inclination that detects, can obtain according to the pythagorean theorem because of the height that the inclination made the water tank reduce or increase, with this height compensation to the water level detection in order to avoid the height that the water spilled over under the renewal tilt state, with the water level height data of actual detection and the full threshold value comparison of water after the renewal to carry out full detection, reduce because of the influence that electrical equipment inclined to full detection of water, improved electrical equipment full detection's accuracy.

In one embodiment, interaction device 230 includes a display and keys connected to main controller 210. The display may be a Light Emitting Diode (LED) display or a Liquid Crystal Display (LCD) display. The user can send a query instruction to the main controller 210 through the keys, and after the main controller 210 receives the query instruction, the detected inclination angle of the electrical equipment can be displayed through the displayer, so that data query through man-machine interaction is realized, and the use convenience of the electronic equipment is improved.

In another embodiment, the interaction device 230 includes a touch display screen connected to the master controller 210. Human-computer interaction is carried out by utilizing the touch display screen, and the operation is simple, convenient and quick.

In one embodiment, the main controller 210 is further configured to send a dumping power-off protection command to the power supply circuit 220 when detecting that the tilt angle of the electrical apparatus reaches the set angle threshold; the dumping power-off protection command is used for controlling the power supply circuit 220 to stop supplying power to the electrical equipment.

Specifically, the power supply circuit 220 is connected to the main controller 210, and is connected to an external commercial power for processing and then supplies power to the main controller 210. When the electrical equipment is detected to be completely toppled, the main controller 210 sends a toppled power-off protection instruction to the power supply circuit 220, so that the power supply circuit 220 stops supplying power. When the situation that the whole electrical equipment is toppled is judged, the circuit can be cut off in time, and therefore power-off protection is achieved.

In order to better understand the electrical equipment and the tilt angle detecting device thereof, the following detailed explanation is provided with reference to specific embodiments.

The application provides an electrical equipment and inclination detection device thereof utilizes the slip resistance card to detect whether electrical equipment takes place the slope, not only can detect whether the electrical equipment inclines, but also can detect inclination to judge the influence of slope to electrical equipment, solved the product of taking the storage water tank in the use, if the problem that the complete machine slope was leaked after the water tank water was full, and the power-off protection problem when the complete machine tumbles.

When the complete machine of the electrical equipment can not keep horizontal work, the risk that the complete machine does not give an alarm to continue working when the water tank is full of water exists. The sliding resistance piece is adopted to detect the inclination angle of the water tank, so that the problem that the water tank is full of water can be solved according to the detected inclination angle of the water tank when the whole machine cannot work in a horizontal state. The user experience is improved. When the whole machine is overturned, the resistance detection circuit 122 detects the change of the resistance according to the rotating angle of the sliding resistance piece, the whole machine is judged to be overturned, the circuit can be cut off in time, and power-off protection is achieved.

The sliding resistance sheet is equivalent to a sliding resistor induced by gravity, the device is vertically arranged on a horizontal panel of an electric appliance, and when the electric appliance is inclined, the sliding resistance sheet slides, so that the contact is changed, and the resistance value is changed along with the change. Adopt the slope degree of sliding resistance card detection water tank, solve when the complete machine can not keep the horizontality work, also can realize full water detection according to the water tank inclination that detects. In addition, whether the electrical equipment has a rollover accident or not can be detected through the sliding resistance card, and power-off protection is performed in time.

Specifically, if the whole electrical equipment works in a horizontal state, the resistance value of the sliding resistance sheet is R1, when the whole electrical equipment tilts, the sliding resistance sheet slides along with the sliding resistance sheet, the resistance value of the sliding resistance sheet changes at the moment and ranges from R1 to R2, and when the whole electrical equipment completely tilts, the resistance value is R2.

If the whole machine does not work in a horizontal state, the resistance detection circuit 122 detects that the resistance value of the sliding resistance card changes, that is, the electric appliance is in an inclined state, the acquired inclination angle is theta 1, and the inclination angle is fed back to the MCU. The topmost end of the sliding resistance piece is provided with a convex angle, when the electrical equipment is completely inclined, the convex angle is just clamped with the contact, the inclination angle is about 90 degrees, and when the electrical equipment is slightly inclined, theta 1 is smaller than 90 degrees. If the inclination angle is completely inclined, the MCU gives an electric appliance inclination power-off protection instruction at the moment, the power supply circuit 220 is controlled to stop supplying power, and the MCU performs power-off protection when the electric appliance is completely inclined or the water level overflows; if the inclination angle is in a slightly inclined state, the MCU can prompt a road surface unevenness instruction. If the uneven road surface does not affect the operation of the equipment, the user can remove the instruction for prompting the uneven road surface, and the system can add the inclination angle into the water fullness detection algorithm. Specifically, after the user releases the instruction for prompting the uneven road surface, the MCU readjusts the water full detection according to the inclined angle. Taking the water tank inclination angle triggering the water full detection as an example of theta 0, the resistance detection circuit 122 detects that the current water tank inclination angle is theta 1, if theta 1> theta 0, the margin of the compensation angle is calculated into the water full detection algorithm, the height of the water tank reduced or increased due to the inclination angle is obtained according to the pythagorean theorem, and the height is compensated to the water level detection so as to update the height of avoiding water overflow under the inclined state, thereby avoiding the water level overflow and achieving the purpose of water full detection under the inclined state.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
