background

Conventionally, a washing machine having the following structure is proposed: charged fine particulate water generated by electrostatic atomization is discharged into a water tank and a washing tank rotatably disposed in the water tank (see, for example, patent document 1). The washing machine uses the charged corpuscle water to remove and deodorize the bacteria attached to the clothes and the bacteria in the circulated air.

Fig. 7 is a schematic cross-sectional view of the washing machine described in patent document 1.

As shown in fig. 7, the washing machine of patent document 1 includes a main body 73, a water tank 75 mounted in the main body 73, a washing tank 74, and the like. The main body 73 constitutes an outer contour of the washing machine. The water tank 75 is elastically supported in the main body 73 so as to be swingable. The washing tub 74 is rotatably disposed in the water tub 75.

The washing tub 74 has a large number of small holes and is rotated by a motor 76. The water tank 75 is connected to a water supply passage 77 and a water discharge passage 78. The water tank 75 is formed with an opening 79 at the front. The opening 79 is openably and closably opened and closed by a door 80.

The main body 73 includes a housing 82 therein. The housing 82 has an electrostatic atomization generator 81 and a fan 83 disposed therein. The housing 82 is connected in communication with one end of an air supply hose 84 constituting an air supply passage. The other end of the air supply hose 84 is opened to the main body 73 to be connected to the outside.

The housing 82 is also connected in communication with one end of a bleed hose 85. The other end of the discharge hose 85 is disposed at an end of the opening 79 of the water tank 75 so as to face the inside of the washing tank 74.

the washing machine of patent document 1 is configured as described above.

The washing machine having the above-described structure first generates charged corpuscle water of nanometer size by the electrostatic atomization generating device 81 before the washing step. The generated charged fine particulate water is discharged into the washing tub 74 through the discharge hose 85 together with the outside air supplied through the air supply hose by the operation of the fan 83. Thus, pretreatment such as sterilization and deodorization of the laundry loaded into the washing tub 74 is performed in advance. The washing step is performed after the pretreatment for sterilization and deodorization of the laundry.

However, in the conventional configuration, the devices such as the electrostatic atomization generator 81 and the like are continuously operated to generate and supply the charged fine particulate water. Therefore, particularly when the washing end time is preset, the operation of the washing program is started after the pretreatment step of sterilization and deodorization. That is, the sterilizing and deodorizing step is started 0.5 to 2 hours before the start of the operation of the washing program. Therefore, the laundry put into the washing tub may be left for a long time until the sterilization and deodorization step is performed. This may cause the growth of bacteria attached to the clothes and the increase in odor associated therewith, which may prevent effective sterilization and deodorization.

Disclosure of Invention

The present invention intermittently performs operation control of devices for generating and supplying a substance having sterilization, deodorization, and antibacterial effects (hereinafter referred to as "functional substance") such as charged corpuscle water. This suppresses the growth of bacteria adhering to the clothes in the time slot during the scheduled operation and the increase of odor caused thereby. Further, a washing machine capable of improving durability of devices and saving energy is provided.

Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited to the embodiment.

(embodiment mode)

Next, the structure of the washing machine according to the embodiment of the present invention will be described with reference to fig. 1 to 3.

Fig. 1 is an external perspective view of a washing machine according to an embodiment of the present invention. Fig. 2 is a longitudinal sectional view of the washing machine. Fig. 3 is a circuit block diagram of the washing machine.

As shown in fig. 1 to 3, the washing machine of the present embodiment includes: a casing 6 having a door 4, and a water tank 8, a washing tank 2, and the like mounted in the casing 6. The housing 6 constitutes an outer contour of the washing machine. The water tank 8 is supported in the housing 6 so as to be swingable. The washing tub 2 is rotatably disposed in the water tub 8. The washing tub 2 is configured in a bottomed cylindrical shape, and many small holes 18 are formed on the entire outer peripheral portion.

In the following, for example, as shown in fig. 1, the case 6 will be described with the door 4 side being a front side, the opposite side of the door 4 being a rear side, the right side being a right side from the front side toward the rear side, and the left side being a left side.

the water tank 8 has a motor 14 disposed on the back surface side. Motor 14 is coupled to washing tub 2 and rotates washing tub 2 in the forward and reverse directions.

The housing 6 has an inclined surface inclined upward toward the rear surface on the front surface side of the water tank 8. The inclined surface is provided with an opening. The opening is openably and closably covered by a door 4. By opening door 4, laundry 20 can be put into washing tub 2 or laundry 20 can be taken out from washing tub 2.

The water tank 8 is supported in a vibration-proof manner so as to be swingable by a vibration-proof mechanism 7 disposed below the housing 6 and a spring body (not shown) disposed above. The water tank 8 is provided with a drain valve 31 at a lower portion. The washing water in the water tank 8 is discharged to the outside by opening the drain valve 31.

A water supply valve 30 is disposed at an upper portion in the housing 6. The water supply valve 30 is composed of a plurality of valves that can open and close two or more water paths. Water is supplied into water tank 8 by opening water supply valve 30.

An operation display unit 5 for a user to select an operation procedure is disposed on the upper portion of the front surface of the housing 6. The user performs input such as selection of a procedure via an input setting unit (not shown) of the operation display unit 5. The input information is displayed on a display unit (not shown). This allows the user to confirm the input information.

A control device 9 is disposed in the upper interior of the casing 6, and the control device 9 includes a control unit 25 configured by a microcomputer or the like, for example.

The control device 9 includes a substrate cooling fan motor 15. The substrate cooling fan motor 15 is driven during operation of the washing machine to cool the control device 9. This suppresses the temperature rise of the control device 9 during operation.

as shown in fig. 3, the controller 25 is connected to, for example, a water level detector 32, a cloth amount detector 33, a door opening/closing detector 34, a timer 35, a storage 36, a motor 14, a drain valve 31, a water supply valve 30, a heat pump unit 10, a sterilization/deodorization device 3 including an electrostatic atomizer, a blower fan motor 13, a substrate cooling fan motor 15, and the like. The control unit 25 controls washing steps such as washing, rinsing, dewatering, and drying steps. Here, the water level detector 32 detects the water level in the water tank 8. The cloth amount detecting unit 33 detects the amount of cloth put into the washing tub 2. The door opening/closing detection unit 34 detects the open/closed state of the door 4.

Specifically, when the user sets the operation contents via the operation display unit 5, the controller 25 receives various data detected by the water level detector 32, the cloth amount detector 33, the door opening/closing detector 34, and the like. Then, the controller 25 controls the operations of the motor 14, the drain valve 31, the water supply valve 30, and the like based on the input data. Thus, the control unit 25 controls the washing steps such as the washing, rinsing, dewatering, and drying steps.

At this time, the controller 25 controls the timer 35 to measure, for example, an elapsed time from an arbitrary time. The control unit 25 stores the various setting contents, the detected data, and the measurement result in the storage unit 36.

The blower fan motor 13 rotates the blower fan 11. Thereby, the air in water tub 8 and washing tub 2 circulates.

That is, in the drying step, the drying air heated by the heat pump unit 10 circulates in the water tank 8 and the washing tank 2. Specifically, the drying air is sent into the first air blowing path 16 by the air blowing fan 11 disposed downstream of the heat pump unit 10 in the circulation air duct 23, and passes through the first air blowing path 16. The air passing through is blown out into the washing tub 2 through the mesh filter 17 from the blow-out port 21 opened on the back side of the water tub 8. The blown air passes between the clothes 20, and takes moisture from the clothes to become a high-humidity state. The air in a high-humidity state is guided to the discharge port 19 formed in the upper portion of the side surface of the water tank 8.

The air guided to the discharge port 19 passes through the filter 22 provided in the second air blowing path 12 of the circulation duct 23. The air in a high humidity state is sent to the heat pump unit 10 and dried, and becomes air for drying. Then, the drying air is circulated by repeating the same operation through the above-described path again.

In the washing machine of the present embodiment, the sterilizing and deodorizing device 3 including the electrostatic atomizing device is disposed downstream of the blower fan 11 in the circulation air duct 23. The sterilization/deodorization device 3 generates functional substances such as charged corpuscle water as described above. The effect substance is circulated together with the above air. This configuration allows elimination and deodorization of laundry 20 in washing tub 2.

That is, the sterilization/deodorization device 3 generates the functional substance when the air flows as the circulating air in the circulating air passage 23. The generated functional substance is discharged from the blow-out port 21 into the washing tub 2 through the mesh filter 17 with the flow of the circulating air. Then, the effect material deeply permeates into the fiber inside of the laundry 20 in the washing tub 2. This allows elimination and deodorization of laundry 20.

The washing machine of the present embodiment is configured as described above.

Next, the operation and action of the washing machine having the above-described configuration will be described with reference to fig. 4 and 5.

Fig. 4 is a timing chart of the sterilization and deodorization step of the washing machine of this embodiment. Fig. 5 is a timing chart of the sterilizing and deodorizing step of the washing machine.

As shown in fig. 4 and 5, the user sets, via the operation display unit 5, a washing step in which the clothes are washed after the sterilization and deodorization step in which the clothes are sterilized and deodorized. At this time, the user selects and sets a reservation function for ending the operation of two consecutive steps, i.e., the sterilization/deodorization step and the washing step, at a set time.

by setting the reservation function, the control unit 25 starts the sterilization and deodorization step when a predetermined time elapses. At this time, as shown in fig. 4, the control unit 25 intermittently drives the sterilizing and deodorizing device 3. The generated effective substance is intermittently discharged toward laundry 20 in washing tub 2 together with the circulated air. When the sterilization and deodorization step for a predetermined time is completed, the control unit 25 starts the washing step and ends the operation at the predetermined time.

that is, in the sterilization and deodorization step, the control unit 25 intermittently operates the sterilization and deodorization device 3. Thereby, the functional substance is intermittently generated and discharged into the washing tub 2.

In the present embodiment, as shown in fig. 5, in the sterilizing and deodorizing step, the control section 25 controls each control device as follows. Specifically, the controller 25 controls the operation of the sterilizing and deodorizing device 3 so that the sterilizing and deodorizing device 3 repeats a cycle of, for example, starting up for P1 time (e.g., 400sec) and stopping for P2 time (e.g., 3200 sec). Similarly, the controller 25 sets a delay time of P5 time (for example, 1sec) for the operation of the sterilizing and deodorizing device 3, and intermittently operates the blower fan motor 13, the motor 14, and the substrate cooling fan motor 15 in a cycle of P3 time (for example, 600sec) and P4 time (for example, 3000 sec). The delay time P5 is set so that the generated functional substance is supplied in a stable circulating manner.

At the time P3, which is the activation time of the motor 14 shown in fig. 5 at the corresponding 1, the washing tub 2 is driven by the normal rotation 10sec and the reverse rotation 10sec, which rotate at a low speed of 45r/min and are stopped (for example, 4sec) between the normal rotation and the reverse rotation.

The washing machine of the present embodiment operates as described above.

next, a washing operation of the washing machine will be described with reference to fig. 6.

Fig. 6 is a flowchart showing a washing operation including a sterilization and deodorization step of the washing machine.

As shown in fig. 6, the user sets the operation course via the operation display unit 5, and the washing operation is started.

When the washing operation is started, first, the controller 25 detects whether the door 4 is in the closed state by the door opening/closing detector 34 (step S1). If it is detected that door 4 is closed (yes at step S1), controller 25 determines whether laundry 20 is present in washing tub 2 by using cloth amount detector 33 (step S2). If there is laundry (yes in step S2), control unit 25 checks whether or not a scheduled operation for setting an operation end time is set (step S3).

when the scheduled operation is set (yes in step S3), the control unit 25 checks whether or not the sterilization and deodorization step is set before the washing step (step S4).

When the sterilization and deodorization step is set (yes in step S4), the control unit 25 intermittently operates the sterilization and deodorization device 3 as described above based on fig. 4 and 5. Then, the generated effect substance is intermittently discharged into the washing tub 2 (step S5).

When the sterilization and deodorization step is finished, the control unit 25 performs the operation of the washing step (step S6).

Then, the control unit 25 ends the operation of the washing step at the preset time.

if there is no laundry in washing tub 2 (no in step S2), control unit 25 checks whether or not the sterilization and deodorization step is set (step S7). When the sterilization and deodorization step is set (yes in step S7), the control unit 25 intermittently operates the sterilization and deodorization device 3 to perform sterilization and deodorization in the water tub 8 and the washing tub 2 (step S8). Then, the control unit 25 ends the operation to end the operation of the washing machine.

If the scheduled operation is not set (no in step S3), controller 25 executes the washing step (step S6).

If the sterilization and deodorization step is not set (no in step S4), control unit 25 executes the washing step (step S6). Then, control unit 25 ends the washing operation to end the operation of the washing machine.

accordingly, controller 25 intermittently operates sterilization/deodorization device 3 to perform sterilization/deodorization in laundry 20, water tub 8, and washing tub 2. Therefore, the growth of bacteria adhering to the clothes is suppressed, and the increase of odor caused thereby is suppressed. At the same time, the intermittent operation can improve the durability of the devices such as the sterilizing and deodorizing device 3 and save energy.

As described above, the washing machine of the present embodiment is set to continuously perform the sterilization and deodorization step and the washing step via the operation display unit 5. When the scheduled operation is set in the operation process, the sterilizing and deodorizing device 3 is intermittently operated for a predetermined on/off time when the predetermined time has elapsed. Thereby, the functional substances such as the charged corpuscle water are discharged to the laundry 20 in the washing tub 2. Thereafter, the washing step is performed. Therefore, the growth of bacteria adhering to clothes 20 in washing tub 2 is suppressed, and the increase in odor associated therewith is suppressed. At the same time, the intermittent operation can improve the durability of the devices such as the sterilizing and deodorizing device 3 and save energy.

In the sterilizing and deodorizing step, the control unit 25 causes the blower fan motor 13, the motor 14, and the substrate cooling fan motor 15 to be started with a delay of a short time (for example, 1 second) from the start time of the sterilizing and deodorizing device 3. The control unit 25 performs control for intermittently operating the motors for a predetermined on/off time. This suppresses the growth of bacteria adhering to clothes 20 in washing tub 2 and the increase in odor associated therewith. At the same time, the intermittent operation can improve the durability of the devices such as the sterilizing and deodorizing device 3 and save energy.

As described above, the washing machine of the present invention includes the electrostatic atomization device for generating the charged fine particulate water and discharging the charged fine particulate water into the washing tub. The washing machine is configured to perform a series of washing steps for washing the laundry in the washing tub after a pretreatment step of discharging the charged fine particle water into the washing tub by the electrostatic atomization device, and to intermittently operate the electrostatic atomization device in the pretreatment step. Thus, the reproduction of bacteria attached to clothes accommodated in the washing tank is prevented during the scheduled operation, and the increase of odor caused thereby is prevented. At the same time, by the intermittent operation, it is possible to improve the durability of the devices for generating and supplying the functional substance and to save energy.

Further, the washing machine of the present invention includes: a washing tank for storing laundry; an electrostatic atomization device which generates charged corpuscle water and discharges the charged corpuscle water into a washing tank; and a control device for performing a series of washing steps for washing the laundry in the washing tub. The electrostatic atomization device comprises a charged particle generation part for generating charged particle water and an air supply fan for supplying the charged particle water generated by the charged particle generation part into the washing tank. The control device is configured to perform a pretreatment step in which charged fine particle water is intermittently discharged into the washing tank by the electrostatic atomization device, and to perform a washing step after the pretreatment step. Thus, the reproduction of bacteria attached to clothes accommodated in the washing tank is prevented during the scheduled operation, and the increase of odor caused thereby is prevented. At the same time, by the intermittent operation, it is possible to improve the durability of the devices for generating and supplying the functional substance and to save energy.

In the washing machine of the present invention, the control device may be configured to operate the charged fine particle generating unit in synchronization with the blower fan. This makes it possible to efficiently suppress bacteria and odor with low power consumption.

In addition, the control device of the washing machine according to the present invention may be configured to delay the intermittent operation of the blower fan with respect to the intermittent operation of the charged fine particle generating unit. This makes it possible to supply air having stable humidity to the vicinity of the high-voltage application electrode of the sterilization and deodorization device.

Further, the washing machine of the present invention includes: a water tank; a washing tank rotatably disposed in the water tank for storing laundry; a motor for rotating the washing tank; an electrostatic atomization device which generates charged corpuscle water and discharges the charged corpuscle water into a washing tank; and a control device for performing a series of washing steps for washing the laundry in the washing tub. The electrostatic atomization device comprises a charged particle generation part for generating charged particle water and an air supply fan for supplying the charged particle water generated by the charged particle generation part into the washing tank. The control device is configured to perform a pretreatment step in which charged fine particle water is intermittently discharged into the washing tank by the electrostatic atomization device, and to perform a washing step after the pretreatment step. Thus, the reproduction of bacteria attached to clothes stored in the washing tank is prevented during the scheduled operation, and the increase of odor caused thereby is prevented. At the same time, by the intermittent operation, it is possible to improve the durability of the devices for generating and supplying the functional substance and to save energy.

In the washing machine of the present invention, the control device may be configured to operate the motor, the cooling device, the charged particle generating unit, and the blower fan in synchronization with each other. This can efficiently suppress the generation of bacteria, odor, and the like with low power consumption.

in the control device for a washing machine according to the present invention, at least one of the charged fine particle generating unit and the blower fan may be intermittently operated. Thus, the step of suppressing the bacterial odor can be continued for a long time or for a long period of time as a pretreatment of the washing step.

The control device for a washing machine according to the present invention may be configured to intermittently operate the motor. Thus, the step of suppressing the bacterial odor can be continued for a long time or for a long period of time as a pretreatment of the washing step.

In addition, the washing machine control device of the present invention may have a reservation function of setting a time for performing the washing step. Thereby, usability of the washing machine is improved. In addition, the method prevents the propagation of bacteria attached to the clothes in the washing tank during the reserved operation, and prevents the increase of odor caused by the propagation. At the same time, by the intermittent operation, it is possible to improve the durability of the devices for generating and supplying the functional substance and to save energy.

Industrial applicability

The washing machine of the invention enables a degerming and deodorization device to operate intermittently to degerming and deodorization clothes. This suppresses the growth of bacteria adhering to the clothes and the accompanying increase in odor, and can improve the durability of the devices and save energy. Therefore, the present invention can be applied to other washing machines such as a vertical washing machine.
