[0054] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application are described in detail below with reference to the accompanying drawings and examples. Obviously, the described embodiments are only some of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other implementation methods obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0055] Existing fresh air systems of washing machines are all achieved by setting up fresh air inlets, fresh air inlet channels, fans and other components inside the washing machine. Since the fresh air inlet channels take up a large space, after adding these components, either the overall volume of the washing machine needs to be increased or the space of the washing machine needs to be reduced.

[0056] To solve this problem, refer to Figure 1 , an embodiment of the present application provides a washing machine, comprising a door 9 and a body 10;

[0057] There are two locking states between the door 9 and the body 10;

[0058] When the door 9 and the body 10 are in the first locking state, the door 9 and the body 10 are completely closed;

[0059] When the door 9 and the body 10 are in the second locking state, there is a gap between the door 9 and the body 10 .

[0060] That is, based on the fact that the traditional door 9 and body 10 only have two states, closed and open, in this application, the closed state is divided into a first locked state and a second locked state. The first locked state is the locked state when the washing machine is running. At this time, the door 9 and body 10 are tightly connected and completely closed, and air cannot enter or exit through the connection between the door 9 and the body 10, so fresh air cannot be introduced at this time. In the second locked state, the door 9 is also stationary, but there is a gap between the door 9 and the body 10. The size of this gap is determined according to actual needs. The purpose of setting the gap is to allow air to enter the washing machine through this gap when the washing machine is in this state. In this way, fresh air can be introduced without adding an internal fresh air channel to the washing machine.

[0061] The first locking state and the second locking state are achieved by the lock hook 3 and the electromagnetic door lock buckle 6 .

[0062] In one embodiment, if Figure 1 As shown, the door 9 is provided with a lock hook 3, and the body 10 is provided with an electromagnetic door lock buckle 6;

[0063] like Figure 2 As shown, the locking hook 3 includes a first travel locking hole 1 and a second travel locking hole 2;

[0064] When the electromagnetic door lock buckle 6 is located in the second travel lock hole 2, the door 9 and the body 10 are in a first locking state;

[0065] When the electromagnetic door lock buckle 6 is located in the first travel lock hole 1 , the machine door 9 and the machine body 10 are in a second locking state.

[0066] In another embodiment, the door 9 is provided with a lock hook 3, and the body 10 is provided with an electromagnetic door lock buckle 6;

[0067] like Figure 2 As shown, the lock hook 3 includes a first travel lock hole 1 and a second travel lock hole 2, and the electromagnetic door lock buckle 6 includes a first electromagnetic door lock buckle and a second electromagnetic door lock buckle;

[0068] When the second electromagnetic door lock buckle is located in the second travel lock hole 2, the door 9 and the body 10 are in a first locking state;

[0069] When the first electromagnetic door lock buckle is located in the first travel lock hole 1, the machine door 9 and the machine body 10 are in a second locking state.

[0070] In actual use, the lock hook can also be set on the machine body, and the electromagnetic door lock buckle is set on the machine door.

[0071] As an implementation method of the embodiment of the present application, the first locking state and the second locking state can be manually controlled by a person.

[0072] As a preferred implementation method of the present application, the first and second locking states can be automatically controlled by the washing machine's control device. In addition to requiring a new control program to be written into the washing machine's control device, automatic control also requires a push device 7 in terms of hardware for pushing the door 9 to change the door 9 and the machine body 10 from the first locking state to the second locking state. Exemplarily, the push device 7 is composed of a motor and a push rod. When the washing machine is in the first locking state, the washing machine's control device sends a signal to the motor, which drives the push rod to push the electromagnetic door lock buckle 6 from the first travel lock hole 1 to the second travel lock hole 2.

[0073] If there are two electromagnetic door lock buckles 6, the second electromagnetic door lock buckle is pushed into the second stroke lock hole 2.

[0074] like Figure 1 As shown, the pushing device 7 is mounted on the machine body 10. Of course, it can also be mounted on the machine door 9 as needed.

[0075] It should be noted that, when the door needs to be opened, the door 9 can also be pushed open by a driving device.

[0076] In this way, the first locking state can be changed to the second locking state by the pushing device 7.

[0077] In one embodiment, if a user wants to change from the second locking state to the first locking state, the user can manually change the state.

[0078] In another embodiment, the present application uses a magnetic device 5 and a magnetic accessory 4 to achieve the transition from the second locked state to the first locked state. Specifically, after the magnetic device 5 is powered on, it can generate an attractive force to attract the magnetic accessory 4. In this way, as long as the magnetic device 5 and the magnetic accessory 4 are placed on the body 10 and the door 9 respectively, the door 9 can be changed from the second locked state to the first locked state.

[0079] In one embodiment, the magnetic device 5 is mounted on the appliance door 9, and the magnetic accessory 4 is mounted on the appliance body 10. However, since the magnetic device 5 requires circuit control, and it is inconvenient to install circuits on the appliance door 9, the magnetic device 5 is generally mounted on the appliance body 10, and the magnetic accessory 4 is mounted on the appliance door 9.

[0080] It should be noted that although this application provides Figure 1 It is a drum washing machine, but the solution of the present application can still be applied to a pulsator washing machine.

[0081] While the second lock state is designed to allow only air to pass through, sufficient fresh air requires water to pass through the gaps. To prevent excessive water flow, the second lock state is only used during preset periods, such as during the spin or drain phases of the wash cycle, and when the water level is low. This is especially true for pulsator washing machines, where the door is located at the top, which reduces water leakage due to gravity.

[0082] Even in these modes, water leakage is inevitable in the drum washing machine. In order to prevent the leaked water from causing trouble to the user, the embodiment of the application further provides a water receiving tray 8. It is arranged under the body 10 and is used to receive water leaking from the gap in the second locking state.

[0083] In one embodiment, the water receiving tray 8 is fixed below the body 10. However, since it is fixed below the body 10, the occupied space of the washing machine will be increased, affecting people's use.

[0084] Therefore, in another embodiment, the water receiving tray 8 is movably provided;

[0085] When in the second locking state, the water receiving tray 8 extends from the body 10;

[0086] When not in the second locking state, the water receiving tray 8 is retracted into the machine body 10. The extension and retraction of the water receiving tray 8 are achieved by a motor and a corresponding transmission structure, which can be specifically configured according to implementation needs.

[0087] In the second locked state, the water tray 8 extends from the housing 10. Alternatively, the water tray 8 may extend from the housing 10 throughout the second locked state. Alternatively, a sensor may be provided to detect whether water is leaking from the gap, and the water tray 8 may be extended from the housing 10 only when leakage is detected.

[0088] In order to prevent the water receiving pan 8 from being filled with too much water, a pipe can be provided to connect the water in the water receiving pan 8 to the original drainage circuit of the washing machine, and the water in the water receiving pan 8 can be discharged through the drainage pump of the washing machine.

[0089] As a preferred implementation method of the embodiment of the present application, the water receiving tray 8 is detachably connected, that is, the user can remove the water receiving tray 8 from the body 10 for easy cleaning, and for easy pouring of water when not connected to the drain pump.

[0090] The washing machine provided in the embodiment of the present application includes a door 9 and a body 10. The door 9 and the body 10 have two locking states. When the door 9 and the body 10 are in the first locking state, the door 9 and the body 10 are completely closed. When the door 9 and the body 10 are in the second locking state, there is a gap between the door 9 and the body 10. The gap can release the closed state of the washing machine to allow fresh air to enter the washing machine. During normal use, a closed space can be formed through the first locking state, which does not affect the normal use of the washing machine. This solution does not require additional components inside the washing machine, will not increase the volume of the washing machine or reduce the washing space, and greatly improves the user experience.

[0091] Based on the same inventive concept, the present application also provides a washing machine control method, such as Figure 3 As shown, the method applied to the washing machine provided in the above embodiment includes:

[0092] S31: Acquire the current operating state of the washing machine, where the operating state includes an operating mode and an operating stage.

[0093] S32: When the current operating state is in a preset operating state, if the target parameter corresponding to the current operating state meets the preset condition, the washing machine is controlled to change from the first locking state to the second locking state, or the washing machine is controlled to change from the second locking state to the first locking state.

[0094] In one embodiment, when the current operating state is in a preset operating state, if the target parameter corresponding to the current operating state meets a preset condition, controlling the washing machine to change from the first locking state to the second locking state includes:

[0095] When the washing machine is in the draining or spinning phase of the wash mode, if the water level in the washing machine falls below a preset water level, the washing machine is controlled to switch from the first locking state to the second locking state, and the speed of the washing machine is adjusted to the preset speed. This adjustment to the preset speed is because a speed that is too high will cause the clothes to stick to the drum wall, while a speed that is too low will prevent the clothes from being lifted to the high position and flipped over by the lifting ribs. These situations will reduce the effective contact area between the clothes and the fresh air. The reason for the water level falling below the preset water level is that when the water level is high, water may flow out through the gaps.

[0096] It should be noted that if it is a washing machine and dryer, the fan should be turned on (no hot air should be blown at this time, that is, the heating device of the fan should not be turned on) to speed up the air flow.

[0097] When the washing machine completes the drainage stage and needs to enter the dehydration stage, the washing machine is controlled to change from the second locking state to the first locking state.

[0098] In another embodiment, if the washing machine is a washing machine and the current operating state is in a preset operating state, if the target parameter corresponding to the current operating state satisfies a preset condition, controlling the washing machine to change from the first locking state to the second locking state includes:

[0099] When the washing machine is in drying mode, if the temperature in the barrel is greater than or equal to the preset temperature, and the drying time is greater than or equal to the first duration, the washing machine is controlled to change from the first locking state to the second locking state, and the speed of the washing machine is adjusted to the preset speed, and the fan of the washing machine is turned on at the same time.

[0100] When the washing machine changes from the first locking state to the second locking state, starting to time the running time;

[0101] When the operating time is the second time, the washing machine is controlled to change from the second locked state to the first locked state. The second time can be a fixed time or a time determined according to the weight of the clothes. Generally speaking, the heavier the clothes, the longer the second time.

[0102] When the washing machine is in the first locking state, if the washing machine meets the drying completion condition, the washing machine is controlled to change from the first locking state to the second locking state, and the heating device for heating the fan is turned off.

[0103] In order to explain the present application scheme in more detail, the following is a structure as follows Figure 1 and Figure 2 The washing machine shown in the figure is used as an example for specific description. Among them, when the electromagnetic door lock buckle 6 is locked in the second stroke lock hole 2, it is in the first locking state, which can ensure the safety of high speed during washing and drying; when the electromagnetic door lock buckle 6 is locked in the first stroke lock hole 1, it is in the second locking state.

[0104] When the washer-dryer is in wash mode, Figure 4 As shown, after the washing machine is loaded, the door 9 is closed, and the electromagnetic door lock buckle 6 is locked in the second stroke lock hole 2, and the whole machine reaches a relatively sealed state. After the main wash phase is completed, drainage begins. After drainage is completed, water level information is fed back through, including but not limited to, liquid level sensors and weight sensors. If the water level is lower than the threshold L1, the fresh air program is started, and the speed is adjusted to Arpm (a preset speed value, set according to actual needs. Too high a speed will cause the clothes to stick to the drum wall, and too low a speed will cause the clothes to not be able to rise to a high position and flip along with the lifting ribs. These situations will reduce the effective contact area between the clothes and the fresh air), so that the clothes are flipped in the drum, the fan is turned on, and the small stroke X1 is pushed out by the pushing device 7, so that the electromagnetic door lock buckle 6 is locked in the first stroke lock hole 1. At this time, the whole drum is in a non-relatively sealed state and the user cannot directly or indirectly touch the inside or edge of the drum with his hands or objects, completing the air exchange in the drum and dissipating the odor in the drum. After running for a corresponding time T according to the clothing weighing gear, the fan is turned off, and the magnetic device 5 cooperates with the magnetic accessory 4 to generate suction to complete the automatic door closing, so that the electromagnetic door lock 6 buckle position is restored from the first stroke lock hole 1 to the second stroke lock hole 2, and the whole machine is restored to a relatively sealed state again. The rinsing process is the same. If it is just a washing process, the last step is a single dehydration. After completing the high-speed dehydration, according to the water level information fed back by the liquid level sensor, if the water level is lower than the threshold L1, the small stroke X1 is pushed out again by the pushing device 7, and the electromagnetic door lock buckle 6 pops out, so that the electromagnetic door lock buckle 6 is stuck in the first stroke lock hole 1, and the above-mentioned fresh air program is run again. After completion, the electromagnetic door lock buckle 6 is popped out from the first stroke lock hole 1 by the magnetic device 5 or the pushing motor 7, and the machine door 9 is fully opened.

[0105] When the washer-dryer is in drying mode, Figure 5As shown, based on the humidity sensor, temperature sensor, etc., when the temperature inside the drum is at least H1 and the drying time is at least T1, the drum speed is reduced to Arpm. The pushing device 7 pushes out a small stroke X1, causing the electromagnetic door lock buckle 6 to lock into the first stroke lock hole 1, exchanging air with the drum outside. After running for a corresponding time T2 according to the clothing weighing gear, the magnetic attraction device 5 is activated, attracting the magnetic attraction accessory 4, causing the electromagnetic door lock buckle 6 to return from the first stroke lock hole 1 to the second stroke lock hole 2. The door is closed and the relative sealing state is restored. The drum speed resumes and drying continues. (This process can be implemented once or multiple times). When the drying end conditions are reached in the barrel, for example, the difference between the air inlet temperature H2 and the air outlet temperature H3 is ≤ Z, and the total drying time is ≥ T3, the speed of the barrel is reduced to Arpm, the electric heating of the fan is turned off, and the fan blows normal temperature air for heat dissipation. The pushing device 7 pushes out the small stroke X1, and the electromagnetic door lock buckle 6 is locked in the first stroke lock hole 1 to complete the exchange with the external temperature and gas. When the temperature in the barrel drops to below H4 where there is no risk of scalding to the user, the large stroke X2 is pushed out by the pushing device 7 so that the electromagnetic door lock buckle 6 is completely popped out from the first stroke lock hole 1, thereby completing the entire washing and drying process.

[0106] A pop-up drain pan 8 can be added below the door 9. A drain pipe connected to a drain pump can be added to prevent water leaks when the door lock is switched. When the door lock is released, an asynchronous motor or a drive mechanism is synchronously controlled to activate the pop-up drain pan 8. When the door 9 is slightly ajar, the drain pan 8 immediately pops out, collecting any leaked water and alerting the user through the washing machine's internal alarm system. The drain pan is also removable for easy cleaning and maintenance.

[0107] The washing machine control method provided in this embodiment features two door lock strokes. By controlling the door lock in different positions, a pusher or asynchronous motor is controlled. By pushing the door lock hook in different areas, the different strokes allow the washing machine to achieve both a slightly open door and a relatively sealed state. Furthermore, by controlling the pusher stroke and the fan and electric heater activation states, a fresh air function is implemented, shortening drying and cooling times.

[0108] Based on the same inventive concept, the present application also provides a washing machine control system, which is applied to the washing machine provided in the above embodiment, including:

[0109] at least one processor and at least one memory;

[0110] The memory stores executable instructions of the processor;

[0111] The processor is configured to execute the identity recognition method provided by the above embodiment.

[0112] The washing machine control system provided in the embodiment of the present application stores executable instructions of the processor in a memory. When the executable instructions are executed, the processor can determine whether the corresponding target parameters meet the preset conditions based on the current operating status of the washing machine. If so, the washing machine is controlled to change from the first locking state to the second locking state, or the washing machine is controlled to change from the second locking state to the first locking state.
