Description

Technical Field

[0001] This application belongs to the field of intelligent electrical appliance technology, specifically relating to a drawer-type washing and care device and a control method, device and medium for the drawer-type washing and care device. Background Technology

[0002] With the development of the garment washing and care industry, various models and styles of garment washing and care equipment have appeared on the market. These washing and care equipment are increasingly favored by users. Among them, drawer-type washing and care equipment is a relatively new type of washing and care equipment. It has a unique design and can reduce the floor space occupied.

[0003] Drawer-type laundry equipment is easy to operate, just like a drawer in a cabinet. Users simply pull out the drawer, put the clothes in, push the drawer back into place, and start the laundry equipment to wash and care for the clothes. After the clothes are washed, users simply pull out the drawer again, take out the clothes, and then push the drawer back into place.

[0004] However, during the operation of drawer-type laundry equipment, the drawer may pop out of the equipment due to vibration, affecting the washing and care process. Summary of the Invention

[0005] This application provides a drawer-type washing and care equipment, as well as a control method, device, and medium for the drawer-type washing and care equipment, to solve the problem of the risk of drawers popping out during operation of the prior art.

[0006] In a first aspect, this application provides a drawer-type washing and care device, the drawer-type washing and care device including a cabinet, a drawer located inside the cabinet, a locking component, a safety switch and a control device, wherein;

[0007] The locking component includes a latch and a base for the latch. The latch is slidably mounted on the drawer, and the base is mounted on the cabinet.

[0008] The safety switch is installed on the cabinet and is used to switch the power on / off state according to the relationship between the displacement distance and the preset threshold. The preset threshold is the maximum travel range of the safety switch, and the displacement distance is the distance between the drawer and the cabinet.

[0009] Both the safety switch and the locking component are communicatively connected to the control device, which controls the latch to pop out or retract based on the working status of the drawer-type washing and care equipment and the on / off status of the safety switch.

[0010] In one possible design, the locking component further includes a traction motor, a traction line, and a roller, with the traction motor and the roller mounted on the base;

[0011] The traction motor is connected to the locking tongue via the roller and the traction line;

[0012] The traction motor is communicatively connected to the control device, which is used to control the latch to extend or retract via the traction motor.

[0013] In one possible design, the safety switch includes a switch body and an operating telescopic component, the operating telescopic component being used to extend and retract according to the relationship between the displacement distance and the preset threshold, the maximum extension and retraction amount of the operating telescopic component being the maximum travel range of the safety switch;

[0014] The switch body is communicatively connected to the control device, and the switch body is used to switch the power on / off state according to the extension and retraction of the operating telescopic member.

[0015] Secondly, this application provides a control method for a drawer-type laundry and care device, applied to the drawer-type laundry and care device as described in the first aspect, the method comprising:

[0016] In response to the execution command of the drawer-type washing and care equipment, the displacement distance between the drawer and the cabinet, as well as the on / off status of the safety switch, are obtained;

[0017] Determine whether the displacement distance is equal to zero;

[0018] If so, when the safety switch is energized, the control latch is locked and the drawer-type washing and care device executes the washing and care program corresponding to the execution command. The locked state is used to indicate that the latch is popped out and the latch is located in the base.

[0019] In one possible design, after the control latch is in a locked state and the drawer-type washing and care device executes the washing and care program corresponding to the execution command, the method further includes:

[0020] Obtain the operating status of the drawer-type washing and care equipment;

[0021] When the operating state is paused or the operation ends, the latch is controlled to be in a retracted state for a preset time. The retracted state is used to indicate that the latch is retracted and the latch leaves the base.

[0022] In one possible design, after controlling the latch to be in a retracted state for a preset time, the method further includes:

[0023] Obtain the on / off state of the safety switch;

[0024] When the safety switch switches from the energized state to the de-energized state, it controls the bolt to be in a free state. The free state is used to indicate that the bolt is ejected and that the bolt is not located in the base.

[0025] In one possible design, after controlling the locking bolt to be in a free state, the method further includes:

[0026] Obtain the on / off state of the safety switch;

[0027] When the safety switch switches from the power-off state to the power-on state, it controls the bolt to continue to remain in the free state until the bolt enters the base.

[0028] In one possible design, if the safety switch does not switch from the energized state to the de-energized state within a preset time period, the method further includes:

[0029] Control the power outage of the drawer-type washing and care device, and control the locking tongue to be in the locked state;

[0030] Alternatively, a prompt message may be output at intervals, the prompt message being used to indicate that the drawer-type washing and care device has stopped or ended operation;

[0031] When the number of times the prompt message is output reaches a preset number, the power to the drawer-type washing and care device is cut off, and the locking tongue is kept in the locked state.

[0032] Thirdly, this application provides a control device for a drawer-type laundry and care device, applied to the drawer-type laundry and care device as described in the first aspect, the device comprising:

[0033] The acquisition module is used to acquire the displacement distance between the drawer and the cabinet, as well as the on / off status of the safety switch;

[0034] The analysis module is used to determine whether the displacement distance is equal to zero;

[0035] The processing module is used to control the latch to be in a locked state and control the drawer-type washing and care device to start when the safety switch is energized if the displacement distance is equal to zero. The locked state is used to indicate that the latch is popped out and the latch is located in the base.

[0036] Fourthly, this application provides a computer-readable storage medium storing computer-executable instructions, which, when executed by a computer, are used to implement the control method for the drawer-type washing and care device as described in the second aspect.

[0037] This application provides a drawer-type laundry and care device, a control method, a device, and a medium for the drawer-type laundry and care device. The drawer-type laundry and care device includes a housing, a drawer located inside the housing, a locking component, a safety switch, and a control device. The locking component includes a latch and a base for the latch. The latch is slidably mounted on the drawer, and the base is mounted on the housing. The safety switch is mounted on the housing and is used to switch between on / off states based on the relationship between a displacement distance and a preset threshold. The preset threshold is the maximum travel range of the safety switch, and the displacement distance is the distance between the drawer and the housing. Both the safety switch and the locking component are communicatively connected to the control device. The control device is used to control the latch to pop out or retract based on the working state of the drawer-type laundry and care device and the on / off state of the safety switch.

[0038] In response to the execution command of the drawer-type washing and care device, the displacement distance between the drawer and the cabinet, and the on / off state of the safety switch are obtained; it is determined whether the displacement distance is equal to zero; if so, when the safety switch is in the on state, the locking tongue is controlled to be in the locked state, and the drawer-type washing and care device is controlled to execute the washing and care program corresponding to the execution command. The locked state is used to indicate that the locking tongue is popped out and the locking tongue is located in the base.

[0039] The drawer-type laundry device in this application uses a safety switch to roughly detect the displacement distance between the drawer and the cabinet. The safety switch also switches the power on / off state according to the relationship between the displacement distance and the preset threshold. The switching signal is transmitted to the control device, which can then control the latch to pop out and retract based on the working state of the drawer-type laundry device and this switching signal.

[0040] When a user starts the drawer-type laundry equipment, the system first obtains the displacement distance between the drawer and the cabinet, as well as the on / off status of the safety switch. When the displacement distance is zero and the safety switch is on, the control device will control the locking tongue to lock the drawer and control the drawer-type laundry equipment to execute the laundry program. In this way, it can not only ensure that the drawer is located inside the cabinet when the drawer-type laundry equipment is running, but also ensure that the drawer can be locked by the locking tongue during operation and will not be pushed out of the cabinet due to vibration.

[0051] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0054] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0055] With the development of technology and the improvement of people's living standards, people are using laundry and care equipment more and more frequently. Among them, drawer-type laundry and care equipment with novel and unique designs and space-saving features has attracted widespread attention. When washing clothes, users simply need to pull out the drawer of the laundry and care equipment, put the clothes inside, and then push the drawer back into its original position to start the machine. After washing and care is complete, users simply need to pull out the drawer again, take out the clothes, and finally push the drawer back into its original position.

[0056] However, during the operation of drawer-type laundry equipment, the drawer may fall out of the housing due to equipment vibration, posing a safety risk.

[0057] Therefore, this application proposes a drawer-type laundry appliance and a method for controlling the drawer-type laundry appliance. The main method utilizes a safety switch in the drawer-type laundry appliance to roughly detect the displacement distance between the drawer and the cabinet. The on / off state of the safety switch is determined based on the displacement distance and the maximum travel range of the safety switch. When the displacement distance is greater than or equal to the maximum travel range, the safety switch is de-energized; when the displacement distance is less than the maximum travel range, the safety switch is energized again. The control device can then determine whether the locking tongue should extend or retract based on the on / off state of the safety switch and the current operating state of the drawer-type laundry appliance. Through the cooperation of the above components, after the user starts the drawer-type laundry appliance, when the detected displacement distance is zero and the safety switch is energized, the locking tongue is extended to lock the drawer, and the drawer-type laundry appliance is started. In this way, the drawer is locked inside the cabinet during the operation of the drawer-type laundry appliance, preventing the drawer from veering out due to vibration.

[0058] A safety switch is a switch that prevents personnel from entering a hazardous area until all safety conditions are met. There are various types, including latch switches, safety magnetic switches, safety door lock switches, safety pull-cord switches, emergency stop buttons, hinged interlock switches, safety enable switches, safety limit switches, and explosion-proof switches. A safety door switch consists of two independent parts: the switch body and the actuating element. When the safety door is opened, the actuating element is pulled out of the switch body, at which point the normally closed contact inside the switch opens via a mechanical rebound device. When the safety door is closed, the actuating element re-enters the switch body, at which point the normally closed contact closes, allowing power to the drive or control system of the machine or equipment to operate.

[0059] The following is combined Figure 1 This application provides a detailed description of the drawer-type washing and care equipment.

[0060] Figure 1 This is a schematic diagram of a drawer-type washing and care device provided in an embodiment of this application. Figure 1 As shown, the drawer-type laundry equipment includes a housing 110, a drawer 120 located inside the housing, a locking component 130, a safety switch 140, and a control device. The drawer-type laundry equipment can be a drawer-type washing machine or a drawer-type dryer; this embodiment does not limit the type.

[0061] like Figure 2 As shown, the locking component 130 includes a latch 131 and a base 132 that matches the latch 131. The latch 131 is slidably mounted on the drawer 120, and the base 132 is mounted on the box 110.

[0062] like Figure 3 As shown, the safety switch 140 is installed on the housing 110 and is used to switch the power on / off state according to the relationship between the displacement distance and the preset threshold. The preset threshold is the maximum travel range of the safety switch 140, and the displacement distance is the distance between the drawer 120 and the housing 110.

[0063] Safety switch 140 and locking component 130 are both communicatively connected to control device. Control device is used to control the latch 131 to pop out or retract according to the working status of drawer-type washing and care equipment and the on / off status of safety switch 140.

[0064] When the user starts the drawer-type washing and care equipment, if the displacement distance between the drawer 120 and the cabinet 110 is zero and the safety switch 140 is energized, the control device will control the locking tongue 131 to pop out. At this time, the locking tongue 131 is located in the base 132 and can lock the drawer. The control device can control the drawer-type washing and care equipment to execute the washing and care program.

[0065] Subsequently, when the user pauses the drawer-type laundry equipment or the drawer-type laundry equipment ends operation, since the displacement distance between the drawer 120 and the cabinet 110 is still zero, the safety switch 140 will continue to be energized. However, at this time, the control device will control the locking tongue 131 to retract for a period of time so that the user can pull out the drawer 120 to take out and put in clothes.

[0066] When the user starts to pull the drawer 120, and the displacement distance between the drawer 120 and the cabinet 110 reaches the preset threshold corresponding to the safety switch 140, the safety switch 140 will immediately switch from the power-on state to the power-off state and will synchronize the switching signal to the control device. At this time, the drawer-type washing and care equipment is in a paused or stopped state. The control device will control the locking tongue 131 to pop out. However, at this time, the locking tongue 131 has already left the base 132 with the drawer 120 and cannot lock the drawer 120. The user can freely pull out and put in the drawer 120 to take out and put in clothes.

[0067] After the user has finished taking out and putting in clothes, they will push the drawer 120 back into the cabinet 110. When the displacement distance between the drawer 120 and the cabinet 110 reaches below the preset threshold, the safety switch 140 will switch from the power-off state to the power-on state, and will also synchronize the switching signal to the control device. At this time, the drawer-type washing and care equipment is still in a paused or stopped state, and the control device will control the locking tongue 131 to continue to remain in the pop-out state. The user continues to push the drawer 120 in. When the locking tongue 131 returns to the base 132 as the drawer 120 moves, since the locking tongue 131 is in the pop-out position, the drawer 120 will be locked in the cabinet 110 after the locking tongue 131 returns to the base 132.

[0068] In a special case, the drawer-type laundry equipment may be in a state of being unpowered or de-energized, and the safety switch 140 will also be de-energized or de-energized accordingly. If there is no displacement between the drawer 120 and the cabinet 110 at this time, the drawer 120 will be locked inside the cabinet 110 because the locking tongue 131 is located inside the base 132. If there is displacement between the drawer 120 and the cabinet 110 at this time, the user can still push the drawer 120 into the cabinet 110 because the locking tongue 131 is in the pop-out position, causing the locking tongue 131 to return to the base 132 and lock the drawer 120. Usually, the displacement between the drawer 120 and the cabinet 110 caused by the user pulling out the drawer 120 is a very short process, and the maximum travel range of the safety switch 140 is also very small. Therefore, the situation where the drawer-type laundry equipment is de-energized because the displacement between the drawer 120 and the cabinet 110 does not exceed the preset threshold can be disregarded.

[0069] Optional, such as Figure 4As shown, the locking component 130 also includes a traction motor 133, a traction line 134, and a roller 135. The traction motor 133 and the roller 135 are mounted on the base 132. The traction motor 133 is connected to the locking tongue 131 through the roller 135 and the traction line 134. The traction motor 133 is communicatively connected to the control device, which is used to control the locking tongue 131 to pop out or retract through the traction motor 133.

[0070] Optionally, as shown in Figure 5, the safety switch 140 includes a switch body 141 and an operating telescopic component 142. The operating telescopic component 142 is used to extend and retract according to the relationship between the displacement distance and a preset threshold. The maximum extension and retraction of the operating telescopic component 142 is the maximum travel range of the safety switch 140. The switch body 141 is communicatively connected to the control device and is used to switch the on / off state according to the extension and retraction of the operating telescopic component 142.

[0071] When the displacement distance between drawer 120 and cabinet 110 is zero, the operating telescopic component 142 is in a compressed state, and the safety switch 140 is in an energized state. Figure 5B When the drawer 120 is pulled out by the user, and a displacement distance begins to occur between it and the cabinet 110, the operating telescopic component 142 begins to extend, and the safety switch 140 remains energized; until the pull-out distance reaches a preset threshold, the operating telescopic component 142 reaches its maximum extension, and the safety switch 140 is then de-energized. Figure 5A No matter how far the user continues to pull the drawer out, the safety switch 140 remains de-energized. Only when the user pushes the drawer 120 back, causing the displacement distance between the drawer 120 and the cabinet to be below a preset threshold, will the telescopic component 142 begin to compress again, and the safety switch 140 will be energized again.

[0072] Assuming the maximum extension of the operating telescopic component 142 of the safety switch 140 is 3.95mm, i.e., the preset threshold is 3.95mm, if the operating telescopic component 142 reaches a length of 19.7mm when fully extended, then the safety switch 140 will be in a de-energized state; if the operating telescopic component 142 reaches a length of 15.75mm when fully compressed, then the safety switch 140 will be in an energized state. Subsequently, if the length of the operating telescopic component 142 is between 15.75mm and 19.7mm, then the safety switch 140 will continue to be in an energized state.

[0073] Based on the cooperation between the above-mentioned components, it is possible not only to roughly determine whether the drawer and the cabinet have undergone significant displacement changes based on the on / off state of the safety switch, but also to control the pop-out and retraction of the latch based on the working status of the drawer-type washing and care equipment and the on / off state of the safety switch.

[0074] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0075] Figure 6 The flowchart of a control method for a drawer-type washing and care device provided in the embodiments of this application Figure 1 .like Figure 6 As shown, the method includes:

[0076] S601, in response to the execution command of the drawer-type washing and care equipment, obtains the displacement distance between the drawer and the cabinet, as well as the on / off status of the safety switch.

[0077] In the above scheme, after the user starts the drawer-type laundry equipment, to start the equipment, it is necessary to first determine whether the drawer is inside the cabinet and whether the safety switch is energized. The laundry program can only be executed normally if the drawer is inside the cabinet. When the safety switch is energized, the drawer may be inside the cabinet, or it may be pulled out but the distance pulled out does not exceed the preset threshold corresponding to the safety switch. Therefore, in addition to determining the on / off state of the safety switch, it is also necessary to combine the displacement distance between the drawer and the cabinet to determine whether the drawer-type laundry equipment can execute the above-mentioned execution commands.

[0078] S602. Determine if the displacement distance is equal to zero.

[0079] In this step, if the displacement distance is zero, it means the drawer is inside the cabinet; if the displacement distance is not zero, it means the drawer is not inside the cabinet. As mentioned above, a displacement distance of zero can be used to determine whether the drawer has been moved when the safety switch is energized.

[0080] S603 If so, when the safety switch is energized, the control latch is in the locked state, and the drawer-type washing and care device is controlled to execute the washing and care program corresponding to the execution command. The locked state is used to indicate that the latch is popped out and the latch is located in the base.

[0081] In the above scheme, if the displacement distance between the drawer and the cabinet is zero and the safety switch is in the energized state, it means that the drawer-type washing and care equipment can execute the execution command issued by the user. However, in order to ensure that the drawer will not be displaced due to vibration during the operation of the equipment, it is necessary to use the locking tongue to lock the drawer in the cabinet. Therefore, it is also necessary to control the locking tongue to pop out and the locking tongue to be located in the matching base.

[0082] S604. If not, then refuse to execute the execution instruction.

[0083] In the above scheme, if the displacement distance between the drawer and the cabinet is not zero, the safety switch may be energized, indicating that there is a displacement distance between the drawer and the cabinet, but the displacement distance has not reached the preset threshold corresponding to the safety switch. Alternatively, the safety switch may be de-energized, indicating that there is a displacement distance between the drawer and the cabinet, and the displacement distance reaches or exceeds the preset threshold corresponding to the safety switch. As long as the drawer is not inside the cabinet, the device cannot start normally, therefore the above execution command will be refused.

[0084] In this embodiment, when the user starts the drawer-type washing and care device, the displacement distance between the drawer and the cabinet, as well as the on / off state of the safety switch, are first obtained. When the displacement distance is zero and the safety switch is on, the control device controls the locking tongue to lock the drawer and controls the drawer-type washing and care device to execute the washing and care program. In this way, not only can the drawer be kept inside the cabinet when the drawer-type washing and care device is running, but the drawer can also be locked by the locking tongue during operation and will not be pushed out of the cabinet due to vibration.

[0085] Figure 7 The flowchart of a control method for a drawer-type washing and care device provided in the embodiments of this application Figure 2 .like Figure 7 As shown, based on the previous embodiment, the method includes:

[0086] S701, in response to the execution command of the drawer-type washing and care equipment, obtains the displacement distance between the drawer and the cabinet, as well as the on / off status of the safety switch.

[0087] S702. Determine if the displacement distance is equal to zero.

[0088] S703 If so, when the safety switch is energized, the control latch is in the locked state, and the drawer-type washing and care device is controlled to execute the washing and care program corresponding to the execution command. The locked state is used to indicate that the latch is popped out and the latch is located in the base.

[0089] S704. Obtain the operating status of the drawer-type washing and care equipment.

[0090] In this step, after the drawer-type laundry equipment is started, the user may pause the machine to add clothes, or the user may need to retrieve clothes after the washing process is complete. In both cases, the user will need to open the drawer. Therefore, the user's need to open the drawer can be determined by observing the changes in the operating status of the drawer-type laundry equipment after it is started.

[0091] S705. When the running status is paused or the running ends, the control latch is kept in a retracted state for a preset time. The retracted state is used to indicate that the latch is retracted and the latch leaves the base.

[0092] In the above scheme, when the user pauses the drawer-type washing and care equipment or the drawer-type washing and care equipment ends operation, since the drawer is tightly locked inside the cabinet by the locking tongue, the displacement distance between the drawer and the cabinet is still zero, and the safety switch will continue to be energized. However, at this time, the control device will control the locking tongue to retract for a period of time so that the user can pull out the drawer to take out and put in clothes, thus meeting the user's need to open the drawer.

[0093] In the specific implementation process, if the user does not retrieve or place clothes within the preset time, the drawer-type laundry equipment needs to be powered off and locked. If there are children in the user's household, they may open the drawer, causing a safety hazard. In this case, the drawer-type laundry equipment can be powered off and locked directly, or it can be powered off and locked after reminding the user multiple times. For example, the drawer-type laundry equipment can be powered off and the locking tongue can be kept in the locked state. Alternatively, a prompt message can be output intermittently to indicate that the drawer-type laundry equipment is paused or has ended. When the number of prompt messages is output reaches a preset number, the drawer-type laundry equipment is powered off and the locking tongue is kept in the locked state.

[0094] S706. Obtain the on / off status of the safety switch.

[0095] In this step, when the user starts to pull the drawer, the drawer begins to move away from the cabinet. If the distance between the drawer and the cabinet has not yet reached the preset threshold corresponding to the safety switch, the safety switch will remain powered on.

[0096] If the user continues to pull the drawer, causing the displacement distance between the drawer and the cabinet to reach a preset threshold, the safety switch will immediately switch from the power-on state to the power-off state.

[0097] S707. When the safety switch is switched from the energized state to the de-energized state, the control bolt is in the free state. The free state is used to indicate that the bolt is out of the base and that the bolt is not in the base.

[0098] In the above scheme, when the safety switch switches from the power-on state to the power-off state, it means that the displacement distance between the drawer and the cabinet has reached the preset threshold corresponding to the safety switch. After receiving the power-on / power-off state switching information of the safety switch, the control device will control the latch to pop out. However, at this time, the latch has already left the base with the displacement of the drawer and cannot lock the drawer. Users can freely pull out the drawer to take out and put in clothes.

[0099] S708. Obtain the on / off status of the safety switch.

[0100] In this step, after the user has finished taking out and putting away the clothes, they will push the drawer back into the box. As the drawer is pushed back, the displacement distance between the drawer and the box gradually decreases. When the displacement distance between the drawer and the box reaches below the preset threshold, the safety switch will switch from the power-off state to the power-on state.

[0101] S709. When the safety switch switches from the power-off state to the power-on state, the control bolt continues to remain in a free state until the bolt enters the base.

[0102] In the above scheme, when the safety switch switches from the power-off state to the power-on state, it means that the displacement distance between the drawer and the cabinet is now below the preset threshold corresponding to the safety switch. After receiving the power-on / off state switching information of the safety switch, the control device will control the latch to continue to remain in the pop-out state.

[0103] As the user continues to push the drawer in, the latch moves along with it, eventually returning to its base. Because the latch is in the pop-out position, the drawer locks itself securely inside the drawer after the latch returns to its base.

[0104] S710. If not, then refuse to execute the execution instruction.

[0105] For steps that are the same as those in the foregoing embodiments, please refer to the description of the foregoing embodiments, and they will not be repeated here.

[0106] In this embodiment, after the drawer-type laundry equipment begins to execute the user's command, the system monitors the operating status of the drawer-type laundry equipment to determine whether the user needs to open the drawer. When the user needs to open the drawer, the latch is retracted. Subsequently, based on the switching status of the safety switch, the system roughly judges the user's pushing and pulling progress of the drawer, and then releases the latch at an appropriate time so that the latch can return to the base as the drawer moves, thus locking the drawer in a timely manner.

[0107] In summary, the control method for the drawer-type laundry equipment provided in this application uses a safety switch in the drawer-type laundry equipment to roughly detect the displacement distance between the drawer and the cabinet. The power-on / off state of the safety switch is determined based on the displacement distance and the maximum travel range of the safety switch. When the displacement distance is greater than or equal to the maximum travel range, the safety switch is de-energized; when the displacement distance is less than the maximum travel range, the safety switch is energized again. The control device can then determine whether the locking tongue should extend or retract based on the power-on / off state of the safety switch and the current operating state of the drawer-type laundry equipment. Through the cooperation of the above components, after the user starts the drawer-type laundry equipment, when the displacement distance is detected to be zero and the safety switch is energized, the locking tongue is controlled to extend to lock the drawer, and the drawer-type laundry equipment is started. In this way, the drawer is locked inside the cabinet during the operation of the drawer-type laundry equipment, preventing the drawer from veering out due to vibration.

[0108] Figure 8 This is a schematic diagram of the structure of a control device for a drawer-type washing and care equipment provided in an embodiment of the present invention, as shown below. Figure 8 As shown, the control device of the drawer-type washing and care equipment may include various functional modules for implementing the aforementioned control method of the drawer-type washing and care equipment.

[0114] Optionally, the processing module 803 can also be specifically used to: after the control latch is in a retracted state for a preset time, obtain the on / off state of the safety switch; when the safety switch switches from the on state to the off state, control the latch to be in a free state, the free state being used to indicate that the latch has popped out and is not located in the base.

[0115] Optionally, the processing module 803 can also be used to obtain the on / off state of the safety switch after the lock tongue is in the free state; when the safety switch switches from the off state to the on state, it controls the lock tongue to continue to remain in the free state until the lock tongue enters the base.

[0116] Optionally, the processing module 803 can also be specifically used to: control the drawer-type washing and care equipment to turn off the power and control the locking tongue to be in a locked state if the safety switch does not switch from the power-on state to the power-off state within a preset time period; or, output prompt information at intervals, the prompt information being used to prompt the drawer-type washing and care equipment to pause or end operation; when the number of times the prompt information is output reaches a preset number, control the drawer-type washing and care equipment to turn off the power and control the locking tongue to be in a locked state.
