Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and particularly provides a laundry equipment and an opening control method thereof. Background Art

[0002] With the pursuit of people for the quality of life, the requirement for the cleanliness of the home environment is also getting higher and higher. When placing a washing machine in a family now, the washing machine is usually placed in a washing machine cabinet, and at the same time, laundry treatment agents (such as detergents, fabric softeners, etc.) are also placed in the washing machine cabinet. When not in use usually, closing the door makes it completely invisible, so that the entire laundry environment is very clean, making people feel relaxed and happy, and can also effectively prevent children from actively opening the cabinet and randomly taking or even accidentally drinking detergents to a certain extent.

[0003] However, the existing cabinets are usually provided with handles. For children who are active and curious, it is very easy to open the cabinet. At the same time, when the user needs to put in the detergent, they need to manually open the door, which is one more step.

[0004] In order to facilitate the user to open the door, it is necessary to set up a prominent and convenient-to-open handle. However, in order to prevent children from randomly opening it, it is necessary to set up an extremely concealed handle, and when opening the door, it is also necessary to prevent children from peeking, which is very contradictory.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0006] In order to solve the above problems in the prior art, that is, to solve the problem that the opening method of the cabinet of the existing washing machine is not ideal enough, the present invention provides an opening control method for a laundry equipment. The laundry equipment includes a cabinet and a washing machine installed in the cabinet. The washing machine has a feeding device capable of automatically feeding laundry treatment agents. The cabinet includes: a cabinet body having a storage chamber capable of storing laundry treatment agents; a door body capable of opening or closing the storage chamber; and an electromagnetic switch disposed between the cabinet body and the door body. The electromagnetic switch can keep the door body in a closed state and allow the door body to automatically open when the electromagnetic switch is turned on, so as to facilitate the user to take and place laundry treatment agents from the storage chamber. The opening control method includes: judging whether the remaining amount of the laundry treatment agent in the feeding device meets a preset condition; and selectively turning on the electromagnetic switch according to the judgment result.

[0007] In a preferred technical solution of the above opening control method, the step of "selectively turning on the electromagnetic switch according to the judgment result" specifically includes: if the remaining amount meets the preset condition, then turn on the electromagnetic switch.

[0008] In a preferred technical solution of the above-described door opening control method, the door opening control method further includes: when the remaining amount meets the preset condition, further determining whether there is a designated user in the set area; if the determination result is "yes", then turning on the electromagnetic switch.

[0009] In a preferred technical solution of the above-described door opening control method, the door opening control method further includes: when the remaining amount meets the preset condition, further determining whether there is a laundry treatment agent in the storage chamber; if the determination result is "yes", then turning on the electromagnetic switch.

[0010] In a preferred technical solution of the above-described door opening control method, the door opening control method further includes: when the remaining amount meets the preset condition, further determining whether there is a designated user in the set area and whether there is a laundry treatment agent in the storage chamber; if both determination results are "yes", then turning on the electromagnetic switch.

[0011] In a preferred technical solution of the above-described door opening control method, the step of "determining whether the remaining amount of the laundry treatment agent in the dosing device meets the preset condition" specifically includes: obtaining the remaining amount of the laundry treatment agent in the dosing device; determining whether the remaining amount is less than a preset value; wherein, the preset condition is that the remaining amount is less than the preset value.

[0012] In a preferred technical solution of the above-described door opening control method, a detection device is provided in the dosing device, and the detection device is configured to be able to emit an alarm signal when the liquid level of the laundry treatment agent in the dosing device drops to a preset position. The step of "determining whether the remaining amount of the laundry treatment agent in the dosing device meets the preset condition" specifically includes: determining whether the alarm signal emitted by the detection device is received; wherein, the preset condition is receiving the alarm signal emitted by the detection device.

[0013] In a preferred technical solution of the above-described door opening control method, the door opening control method further includes: when a door opening instruction input by the user is obtained, then turning on the electromagnetic switch.

[0014] In a preferred technical solution of the above-described door opening control method, the electromagnetic switch is a push-type electromagnetic switch, and the push-type electromagnetic switch is configured to be able to keep the door body in a closed state when in an adsorption state, and to bounce open the door body when the adsorption is released.

[0015] On the other hand, the present invention further provides a laundry device, which includes a controller configured to be able to execute the above-described door opening control method of the laundry device.

[0016] Those skilled in the art can understand that in the preferred technical solution of the present invention, by arranging an electromagnetic switch between the door body and the cabinet body of the cabinet, the opening of the door body can be controlled through the electromagnetic switch. When the electromagnetic switch is turned on, the door body is allowed to open automatically without the need for the user to manually open it, and thus there is no need to set a handle on the door body. Through such an arrangement, it is not only convenient for the user but also can prevent children from casually opening the door body. In addition, by judging whether the remaining amount of the laundry treatment agent in the dispensing device of the washing machine meets the preset conditions to selectively turn on the electromagnetic switch, the intelligent level of the laundry equipment can be improved, and the user experience can be enhanced.

[0017] Further, when the remaining amount meets the preset conditions, it is further judged whether there is a designated user in the set area and whether there is a laundry treatment agent in the storage chamber. If both judgment results are "yes", the electromagnetic switch is turned on. Through such an arrangement, the safety and intelligent level of the laundry equipment are further improved.

[0018] Further, the electromagnetic switch is a push-type electromagnetic switch, and the push-type electromagnetic switch is set to keep the door body closed when in the adsorbed state and to bounce open the door body when the adsorption is released. Through such an arrangement, the structure of the laundry equipment can be simplified, and the automatic opening of the door body can be realized only through the push-type electromagnetic switch.

[0019] In addition, the laundry equipment further provided by the present invention on the basis of the above technical solution has the technical effects possessed by the above door opening control method due to adopting the above door opening control method. And compared with the laundry equipment before improvement, the laundry equipment of the present invention can automatically control the opening of the door body of the cabinet, which is not only convenient for the user but also can prevent children from casually opening the door body.

Detailed implementation manners

[0034] The following describes the preferred implementation manners of the present invention with reference to the drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0035] It should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0036] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] First, refer to Figure 1 , Figure 1 which is a schematic structural view of the laundry equipment of the present invention.

[0038] As Figure 1 shown, the laundry equipment of the present invention includes a cabinet 1 and a washing machine 2. The washing machine 2 is installed in the cabinet 1. The washing machine 2 has a dispensing device (not shown in the figure) capable of automatically dispensing laundry treatment agents (such as detergents or fabric softeners, etc.). The dispensing device stores laundry treatment agents. When washing clothes, the laundry treatment agents can be automatically dispensed into the washing machine 2 without manual dispensing by the user. The cabinet 1 includes a cabinet body 11 and a door body 12. The door body 12 is pivotally connected to the cabinet body 11.

[0039] Continuing to refer to Figure 1 , two chambers are provided in the cabinet body 11. One of the chambers can accommodate the washing machine 2, and this chamber can be called the washing machine accommodation chamber. The washing machine 2 shown in the figure is a front-loading drum washing machine. For the convenience of washing clothes, the washing machine accommodation chamber is open on the side corresponding to the machine door. The other chamber can store laundry treatment agents, and this chamber can be called the storage chamber. The door body 12 can open or close the storage chamber. The user can store the excess laundry treatment agents in the storage chamber of the cabinet 1. When the laundry treatment agents stored in the dispensing device are insufficient, they can be taken out from the storage chamber and added to the dispensing device.

[0040] It should be noted that only one chamber can also be provided in the cabinet body 11. For example, when the washing machine 2 is a top-loading drum washing machine or a pulsator washing machine, the washing machine 2 and the laundry treatment agents can be all placed in this one chamber. The top of the chamber is set to be open, and the side of the chamber can be opened through the door body 12 for taking and placing the laundry treatment agents.

[0041] The cabinet 1 of the present invention further includes an electromagnetic switch. The electromagnetic switch is arranged between the cabinet body 11 and the door body 12. The electromagnetic switch can keep the door body 12 in a closed state, and the electromagnetic switch can be controlled by the controller of the washing machine 2. When the electromagnetic switch is turned on, the door body 12 is allowed to automatically open. Among them, the electromagnetic switch can be arranged on the cabinet body 11 or on the door body 12. Of course, it is preferably to arrange the electromagnetic switch on the cabinet body 11 for convenient wiring layout.

[0042] In this way, the opening of the door body 12 can be controlled by controlling the electromagnetic switch. Moreover, when the electromagnetic switch is turned on, the door body 12 is allowed to open automatically without the user having to open it manually, so there is no need to set a handle on the door body 12. Through such a setting, it is convenient for the user and can prevent children from casually opening the door body 12.

[0043] It should be noted that in order to enable the door body 12 to open automatically when the electromagnetic switch is powered on, an elastic member, such as a spring, can be provided between the cabinet body 11 and the door body 12. Generally, the door body 12 remains closed under the action of the electromagnetic switch, and at this time the spring is in a compressed state. When the electromagnetic switch is turned on, the door body 12 is automatically pushed open by the spring; alternatively, the electromagnetic switch can be set as a push-type electromagnetic switch, which is set to keep the door body 12 closed when in the adsorbed state and to push the door body 12 open when the adsorption is released. Taking the push-type electromagnetic switch set on the cabinet body 11 as an example, generally, the door body 12 is adsorbed by the push-type electromagnetic switch to keep the door body 12 closed. When the door body 12 needs to be opened, the push-type electromagnetic switch is turned on, the magnetism of the push-type electromagnetic switch disappears, the adsorption is released, and the door body 12 is pushed open. Among them, an iron sheet can be provided at the position corresponding to the push-type electromagnetic switch on the door body 12 so that the door body 12 can be adsorbed by the push-type electromagnetic switch.

[0044] The following Figure 2 Taking the push-type electromagnetic switch set on the cabinet body 11 as an example, a preferred embodiment of the push-type electromagnetic switch will be introduced in detail.

[0045] As Figure 2 shown, the push-type electromagnetic switch includes a base body 31, a first electromagnetic member 32, a second electromagnetic member 33, an iron member 34, an elastic member 35, and a movable member 36.

[0046] Among them, the second electromagnetic member 33 is disposed opposite to the iron member 34. The second electromagnetic member 33 is connected to the base body 31. The iron member 34 is connected to the left end of the movable member 36. The right end of the movable member 36 is connected to the first electromagnetic member 32. The movable member 36 can move left and right relative to the base body 31. The left end of the elastic member 35 is connected to the base body 31, and the right end of the elastic member 35 is connected to the movable member 36. The first electromagnetic member 32 can adsorb to the door body 12 to keep the door body 12 closed, and at this time the second electromagnetic member 33 and the iron member 34 are in a suction state to keep the elastic member 35 in a compressed state.

[0047] During the process of closing the door body 12, the first electromagnetic component 32 first contacts the door body 12, the movable component 36 moves leftward, the elastic component 35 is compressed, the iron component 34 is attracted to the second electromagnetic component 33. After the door body 12 is closed, both the first electromagnetic component 32 and the second electromagnetic component 33 maintain suction. The first electromagnetic component 32 is adsorbed to the door body 12 (if the push-and-eject electromagnetic switch is arranged on the door body 12, the first electromagnetic component 32 is adsorbed to the cabinet body 11), so as to keep the door body 12 in a closed state. The iron component 34 is adsorbed to the second electromagnetic component 33, so as to keep the elastic component 35 in a compressed state. When the door body 12 needs to be opened, the magnetism of the first electromagnetic component 32 and the second electromagnetic component 33 disappears, and under the elastic force of the elastic component 35, the door body 12 is bounced open.

[0048] It should be noted that both the first electromagnetic component 32 and the second electromagnetic component 33 can adopt ordinary electromagnetic chucks, which have magnetism when powered on and demagnetize when powered off, or can adopt special electromagnetic chucks, which have magnetism under normal conditions and demagnetize when powered on. A permanent magnet is arranged in this special electromagnetic chuck. Under normal conditions, the suction force is generated by the permanent magnet, and the magnetic force generated when powered on has the opposite polarity to the inherent magnetic force of the permanent magnet, so that the suction forces cancel each other out and the electromagnetic chuck loses suction.

[0049] In addition, it should also be noted that the installation positions of the second electromagnetic component 33 and the iron component 34 can be interchanged. The second electromagnetic component 33 is installed at the left end of the movable component 36, and the iron component 34 is installed on the base body 31. In addition, the iron component 34 can also be replaced with an electromagnetic component.

[0050] Continue to refer to Figure 2 , a first chamber 311 and a second chamber 312 are formed in the base body 31. A partition 313 is arranged between the first chamber 311 and the second chamber 312. The second electromagnetic component 33 and the iron component 34 are located in the first chamber 311, and the elastic component 35 is located in the second chamber 312. The elastic component 35 is a spring. A limiting component 37 is arranged on the movable component 36. The left end of the spring is connected to the partition 313, and the right end of the spring is connected to the limiting component 37. Exemplarily, the movable component 36 is a movable rod, and the spring is sleeved on the movable rod. Of course, multiple springs can also be arranged and evenly distributed along the circumferential direction of the movable rod.

[0051] For the above-mentioned laundry equipment, the present invention also provides an opening control method, which can control the door body to automatically open through the opening control method, and the controller of the washing machine can execute the opening control method of the present invention.

[0052] As Figure 3 shown, the opening control method of the present invention includes the following steps:

[0053] S1: Judge whether the remaining amount of the laundry treatment agent in the dosing device meets the preset condition;

[0054] S2: According to the judgment result, selectively turn on the electromagnetic switch.

[0055] That is to say, it is possible to judge whether to open the door body according to the remaining amount of laundry treatment in the dispensing device. For example, when the remaining amount meets the preset condition, it indicates that the remaining amount of the laundry treatment agent is insufficient. At this time, the electromagnetic switch can be turned on to open the door body so that the user can take out the spare laundry treatment agent from the storage chamber of the cabinet and add it to the dispensing device; or, when the remaining amount meets the preset condition, the electromagnetic switch may not be turned on first, but further judge whether there is a designated user in the set area and / or whether there is a laundry treatment agent in the storage chamber, and then selectively turn on the electromagnetic switch according to the judgment result, etc. Such flexible adjustment and change do not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0056] Preferably, the door opening control method of the present invention further includes: when an opening instruction input by the user is obtained, the electromagnetic switch is turned on.

[0057] That is to say, the user can open the door body by inputting an opening instruction. For example, a control key can be set on the washing machine, and the user inputs the opening instruction through the control key. Or, the user can also input the opening instruction through the washing machine APP on the mobile phone. Or, a voice collection device can be set on the washing machine, and the user can input a voice opening instruction through the voice collection device, etc. Such adjustment and change of the specific input method of the opening instruction do not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention. In addition, there can be only one input method for the opening instruction, or there can be multiple input methods, and the user can input the opening instruction through multiple methods.

[0058] The following will introduce the door opening control method of the present invention in detail in combination with several specific embodiments.

[0059] Embodiment 1

[0060] The following will Figure 4 introduce the technical solution of Embodiment 1 in detail.

[0061] In this embodiment, the preset condition is that the remaining amount of the laundry treatment agent in the dispensing device is less than the preset value.

[0062] As Figure 4 shown, the door opening control method of this embodiment includes the following steps:

[0063] S1: Obtain the remaining amount of the laundry treatment agent in the dispensing device;

[0064] S2: Judge whether the remaining amount is less than the preset value;

[0065] S3: If the remaining amount is greater than or equal to the preset value, do not turn on the electromagnetic switch;

[0066] S4: If the remaining amount is less than the preset value, turn on the electromagnetic switch.

[0067] Exemplarily, a liquid level sensor can be set in the dispensing device of the washing machine to detect the height of the laundry treatment agent in the dispensing device in real time, calculate the remaining amount of the laundry treatment agent based on the height of the laundry treatment agent and the area of the dispensing device, and then compare the remaining amount with the preset value to determine whether the remaining amount is less than the preset value. When the remaining amount is less than the preset value, that is, when the remaining amount meets the preset condition, it indicates that the laundry treatment agent in the dispensing device is insufficient, then turn on the electromagnetic switch to automatically open the door of the cabinet so that the user can take out the stored laundry treatment agent from the storage chamber of the cabinet and add it to the dispensing device; conversely, when the remaining amount is greater than or equal to the preset value, that is, when the remaining amount does not meet the preset condition, it indicates that the laundry treatment agent in the dispensing device is sufficient, then there is no need to turn on the electromagnetic switch.

[0068] Embodiment Two

[0069] Next, in conjunction with Figure 5 introduce the technical solution of Embodiment Two in detail.

[0070] Similar to Embodiment One, in this embodiment, the preset condition is that the remaining amount of the laundry treatment agent in the dispensing device is less than the preset value.

[0071] As Figure 5 shown, the door opening control method of this embodiment includes the following steps:

[0072] S1: Obtain the remaining amount of the laundry treatment agent in the dispensing device;

[0073] S2: Judge whether the remaining amount is less than the preset value;

[0074] S3: If the remaining amount is greater than or equal to the preset value, do not turn on the electromagnetic switch;

[0075] S4: If the remaining amount is less than the preset value, further judge whether there is a designated user in the set area;

[0076] S5: If the judgment result is "yes", turn on the electromagnetic switch;

[0077] S6: If the judgment result is "no", do not turn on the electromagnetic switch.

[0078] Similarly to Embodiment 1, a liquid level sensor can be arranged in the dispensing device to detect the height of the laundry treatment agent in the dispensing device in real time. The remaining amount of the laundry treatment agent is calculated based on the height of the laundry treatment agent and the area of the dispensing device, and then the remaining amount is compared with a preset value to determine whether the remaining amount is less than the preset value. When the remaining amount is less than the preset value, that is, when the remaining amount meets the preset condition, it indicates that the laundry treatment agent in the dispensing device is insufficient. However, at this time, the electromagnetic switch is not turned on immediately. Instead, it is further determined whether there is a designated user in the set area. If the judgment result is "yes", that is, if there is a designated user in the set area, the electromagnetic switch is turned on. If the judgment result is "no", that is, if there is no designated user in the set area, the electromagnetic switch is not turned on. In addition, when the remaining amount is greater than or equal to the preset value, that is, when the remaining amount does not meet the preset condition, it indicates that the laundry treatment agent in the dispensing device is sufficient, and the electromagnetic switch is not turned on either.

[0079] It is further determined whether there is a designated user in the set area to determine whether there is a user operating in front of the washing machine. If there is a designated user in the set area, it means that there is a user operating in front of the washing machine. At this time, the electromagnetic switch can be turned on to automatically open the door body so that the user can take out the laundry treatment agent from the storage chamber of the cabinet and add it to the dispensing device. On the contrary, if there is no designated user in the set area, it means that there is no user operating in front of the washing machine. The user may remotely control the washing machine through the mobile phone APP. At this time, the electromagnetic switch is not turned on to prevent children from accidentally ingesting the laundry treatment agent stored in the storage chamber after finding that the door body of the cabinet is open.

[0080] It should be noted that the set area refers to the area within a certain distance from the laundry equipment. If the designated user is in this set area, it means that the designated user is relatively close to the laundry equipment, and it can be determined that the designated user is operating the washing machine. Among them, information can be collected through devices such as distance sensors or cameras to determine whether there is a designated user in the preset area. In addition, the designated user is not limited to one person. Multiple family members can be set as designated users. As long as there is one designated user in the set area, it can be determined that there is a designated user in the set area.

[0081] Embodiment 3

[0082] The following combines Figure 6 to introduce the technical solution of Embodiment 3 in detail.

[0083] Similarly to Embodiment 1, in this embodiment, the preset condition is that the remaining amount of the laundry treatment agent in the dispensing device is less than the preset value.

[0084] As Figure 6 shown, the door opening control method of this embodiment includes the following steps:

[0085] S1: Obtain the remaining amount of the laundry treatment agent in the dispensing device;

[0086] S2: Determine whether the remaining amount is less than a preset value;

[0087] S3: If the remaining amount is greater than or equal to the preset value, do not turn on the electromagnetic switch;

[0088] S4: If the remaining amount is less than the preset value, further determine whether there is any laundry treatment agent in the storage chamber;

[0089] S5: If the judgment result is "yes", turn on the electromagnetic switch;

[0090] S6: If the judgment result is "no", do not turn on the electromagnetic switch.

[0091] Similarly to Embodiment 1, a liquid level sensor can be provided in the dispensing device to detect the height of the laundry treatment agent in the dispensing device in real time, calculate the remaining amount of the laundry treatment agent based on the height of the laundry treatment agent and the area of the dispensing device, and then compare the remaining amount with the preset value to determine whether the remaining amount is less than the preset value. When the remaining amount is less than the preset value, that is, when the remaining amount meets the preset condition, it indicates that the laundry treatment agent in the dispensing device is insufficient. However, at this time, the electromagnetic switch is not turned on first, but it is further determined whether there is any laundry treatment agent in the storage chamber. If the judgment result is "yes", that is, if there is laundry treatment agent in the storage chamber, the electromagnetic switch is turned on to automatically open the door body so that the user can take out the laundry treatment agent from the storage chamber of the cabinet and add it to the dispensing device; on the contrary, if the judgment result is "no", that is, if there is no laundry treatment agent in the storage chamber, there is no need to turn on the electromagnetic switch; in addition, when the remaining amount is greater than or equal to the preset value, that is, when the remaining amount does not meet the preset condition, it indicates that the laundry treatment agent in the dispensing device is sufficient, and the electromagnetic switch is not turned on either.

[0092] It should be noted that a placement table for placing the laundry treatment agent can be provided in the storage chamber, and a weight sensor can be provided on the placement table to collect data through the weight sensor to determine whether there is any laundry treatment agent on the placement table, or a camera can be provided in the storage chamber to collect the image information in the storage chamber to determine whether there is any laundry treatment agent in the storage chamber.

[0093] Embodiment 4

[0094] The following will be combined with Figure 7 to introduce the technical solution of Embodiment 4 in detail.

[0095] Similarly to Embodiment 1, in this embodiment, the preset condition is that the remaining amount of the laundry treatment agent in the dispensing device is less than the preset value.

[0096] Such as Figure 7As shown in the figure, the door opening control method of this embodiment includes the following steps:

[0097] S1: Obtain the remaining amount of the laundry treatment agent in the dispensing device;

[0098] S2: Determine whether the remaining amount is less than the preset value;

[0099] S3: If the remaining amount is greater than or equal to the preset value, the electromagnetic switch is not turned on;

[0100] S4: If the remaining amount is less than the preset value, further determine whether there is a designated user in the set area and whether there is a laundry treatment agent in the storage chamber;

[0101] S5: If the judgment results are all "yes", the electromagnetic switch is turned on;

[0102] S6: If the judgment result is "no", the electromagnetic switch is not turned on.

[0103] Similar to Embodiment 1, a liquid level sensor can be set in the dispensing device. The liquid level sensor is used to detect the height of the laundry treatment agent in the dispensing device in real time. The remaining amount of the laundry treatment agent is calculated based on the height of the laundry treatment agent and the area of the dispensing device, and then the remaining amount is compared with the preset value to determine whether the remaining amount is less than the preset value. When the remaining amount is less than the preset value, that is, when the remaining amount meets the preset condition, it means that the laundry treatment agent in the dispensing device is insufficient. However, at this time, the electromagnetic switch is not turned on first. Instead, it is further determined whether there is a designated user in the set area and whether there is a laundry treatment agent in the storage chamber. If the judgment results are all "yes", that is, if there is a designated user in the set area and there is a laundry treatment agent in the storage chamber, the electromagnetic switch is turned on. If the judgment result is "no", that is, if there is no designated user in the set area or there is no laundry treatment agent in the storage chamber, the electromagnetic switch is not turned on; in addition, when the remaining amount is greater than or equal to the preset value, that is, when the remaining amount does not meet the preset condition, it means that the laundry treatment agent in the dispensing device is sufficient, and the electromagnetic switch is not turned on either.

[0104] Embodiment 5

[0105] Next, in conjunction with Figure 8 The technical solution of Embodiment 5 will be introduced in detail.

[0106] In this embodiment, a detection device is provided in the dispensing device of the washing machine. The detection device is set to be able to emit an alarm signal when the liquid level of the laundry treatment agent in the dispensing device drops to a preset position. The preset condition is to receive the alarm signal emitted by the detection device.

[0107] Exemplarily, a float level gauge is provided inside the dispensing device. The float of the float level gauge can move downward as the liquid level of the laundry treatment agent inside the dispensing device drops. When the liquid level of the laundry treatment agent drops to a preset position, the float level gauge emits an alarm signal.

[0108] As Figure 8 shown, the door opening control method of this embodiment includes the following steps:

[0109] S1: Determine whether an alarm signal sent by the detection device is received;

[0110] S2: If the alarm signal sent by the detection device is not received, the electromagnetic switch is not turned on;

[0111] S3: If the alarm signal sent by the detection device is received, the electromagnetic switch is turned on.

[0112] When the alarm signal sent by the detection device is received, that is, when the remaining amount meets the preset condition, it indicates that the liquid level of the laundry treatment agent in the dispensing device has dropped to the preset position and the laundry treatment agent is insufficient. Then the electromagnetic switch is turned on to automatically open the door so that the user can take out the laundry treatment agent from the storage chamber of the cabinet and add it to the dispensing device; conversely, when the alarm signal sent by the detection device is not received, that is, when the remaining amount does not meet the preset condition, it indicates that the laundry treatment agent in the dispensing device is sufficient, and there is no need to turn on the electromagnetic switch.

[0113] Embodiment Six

[0114] Next, in conjunction with Figure 9 the technical solution of Embodiment Six will be introduced in detail.

[0115] Similar to Embodiment Five, in this embodiment, a detection device is provided inside the dispensing device of the washing machine. The detection device is configured to be able to emit an alarm signal when the liquid level of the laundry treatment agent in the dispensing device drops to a preset position. The preset condition is that an alarm signal sent by the detection device is received.

[0116] Exemplarily, a float level gauge is provided inside the dispensing device. The float of the float level gauge can move downward as the liquid level of the laundry treatment agent inside the dispensing device drops. When the liquid level of the laundry treatment agent drops to a preset position, the float level gauge emits an alarm signal.

[0117] As Figure 9 shown, the door opening control method of this embodiment includes the following steps:

[0118] S1: Determine whether an alarm signal sent by the detection device is received;

[0119] S2: If the alarm signal sent by the detection device is not received, the electromagnetic switch is not turned on;

[0120] S3: If an alarm signal sent by the detection device is received, further determine whether there is a designated user within the set area;

[0121] S4: If the judgment result is "yes", turn on the electromagnetic switch;

[0122] S5: If the judgment result is "no", do not turn on the electromagnetic switch.

[0123] When an alarm signal sent by the detection device is received, that is, when the remaining amount meets the preset conditions, it indicates that the liquid level of the laundry treatment agent in the dispensing device has dropped to the preset position, and the laundry treatment agent is insufficient. However, at this time, the electromagnetic switch is not turned on first. It is necessary to further determine whether there is a designated user within the set area. If the judgment result is "yes", that is, if there is a designated user within the set area, the electromagnetic switch is turned on. If the judgment result is "no", that is, if there is no designated user within the set area, the electromagnetic switch is not turned on; in addition, when no alarm signal sent by the detection device is received, that is, when the remaining amount does not meet the preset conditions, it indicates that the laundry treatment agent in the dispensing device is sufficient, and there is no need to turn on the electromagnetic switch.

[0124] Further determine whether there is a designated user within the set area to determine whether there is a user operating in front of the washing machine. If there is a designated user within the set area, it means that there is a user operating in front of the washing machine. At this time, the electromagnetic switch can be turned on to automatically open the door body so that the user can take out the laundry treatment agent from the storage chamber of the cabinet and add it to the dispensing device; on the contrary, if there is no designated user within the set area, it means that there is no user operating in front of the washing machine. The user may remotely control the washing machine through the mobile phone APP. At this time, the electromagnetic switch is not turned on to prevent children from accidentally ingesting the laundry treatment agent stored in the storage chamber after discovering that the door body of the cabinet is opened.

[0125] It should be noted that the set area refers to the area within a certain distance from the laundry equipment. If the designated user is within this set area, it means that the designated user is relatively close to the laundry equipment, and it can be determined that the designated user is operating the washing machine. Information can be collected through devices such as distance sensors or cameras to determine whether there is a designated user within the preset area. In addition, the designated user is not limited to one person. Multiple family members can be set as designated users. As long as there is one designated user within the set area, it can be determined that there is a designated user within the set area.

[0126] Embodiment Seven

[0127] The following combines Figure 10 to introduce the technical solution of Embodiment Seven in detail.

[0128] Similarly to Embodiment 5, in this embodiment, a detection device is provided inside the dispensing device of the washing machine. The detection device is configured to emit an alarm signal when the liquid level of the laundry treatment agent in the dispensing device drops to a preset position. The preset condition is receiving the alarm signal emitted by the detection device.

[0129] Exemplarily, a float level gauge is provided inside the dispensing device. The float of the float level gauge can move downward as the liquid level of the laundry treatment agent in the dispensing device drops. When the liquid level of the laundry treatment agent drops to the preset position, the float level gauge emits an alarm signal.

[0130] As Figure 10 shown, the door opening control method of this embodiment includes the following steps:

[0131] S1: Determine whether the alarm signal emitted by the detection device is received;

[0132] S2: If the alarm signal emitted by the detection device is not received, the electromagnetic switch is not turned on;

[0133] S3: If the alarm signal emitted by the detection device is received, further determine whether there is laundry treatment agent in the storage chamber;

[0134] S4: If the judgment result is "yes", the electromagnetic switch is turned on;

[0135] S5: If the judgment result is "no", the electromagnetic switch is not turned on.

[0136] When the alarm signal emitted by the detection device is received, that is, when the remaining amount meets the preset condition, it indicates that the liquid level of the laundry treatment agent in the dispensing device has dropped to the preset position and the laundry treatment agent is insufficient. However, at this time, the electromagnetic switch is not turned on first. It is necessary to further determine whether there is laundry treatment agent in the storage chamber. If the judgment result is "yes", that is, if there is laundry treatment agent in the storage chamber, the electromagnetic switch is turned on to automatically open the door so that the user can take out the laundry treatment agent from the storage chamber of the cabinet and add it to the dispensing device; conversely, if the judgment result is "no", that is, if there is no laundry treatment agent in the storage chamber, there is no need to turn on the electromagnetic switch. In addition, when the alarm signal emitted by the detection device is not received, that is, when the remaining amount does not meet the preset condition, it indicates that the laundry treatment agent in the dispensing device is sufficient, and there is no need to turn on the electromagnetic switch.

[0137] Embodiment 8

[0138] Next, in conjunction with Figure 11 the technical solution of Embodiment 8 will be introduced in detail.

[0139] Similarly to Embodiment 5, in this embodiment, a detection device is provided in the dispensing device of the washing machine. The detection device is configured to emit an alarm signal when the liquid level of the laundry treatment agent in the dispensing device drops to a preset position. The preset condition is receiving the alarm signal emitted by the detection device.

[0140] Exemplarily, a float level gauge is provided in the dispensing device. The float of the float level gauge can move downward as the liquid level of the laundry treatment agent in the dispensing device drops. When the liquid level of the laundry treatment agent drops to the preset position, the float level gauge emits an alarm signal.

[0141] As Figure 11 shown, the door opening control method of this embodiment includes the following steps:

[0142] S1: Determine whether the alarm signal emitted by the detection device is received;

[0143] S2: If the alarm signal emitted by the detection device is not received, the electromagnetic switch is not turned on;

[0144] S3: If the alarm signal emitted by the detection device is received, further determine whether there is a designated user in the set area and whether there is a laundry treatment agent in the storage chamber;

[0145] S4: If the judgment results are all "yes", the electromagnetic switch is turned on;

[0146] S5: If the judgment result is "no", the electromagnetic switch is not turned on.

[0147] When the alarm signal emitted by the detection device is received, that is, when the remaining amount meets the preset condition, it indicates that the liquid level of the laundry treatment agent in the dispensing device has dropped to the preset position and the laundry treatment agent is insufficient. However, at this time, the electromagnetic switch is not turned on first. It is necessary to further determine whether there is a designated user in the set area and whether there is a laundry treatment agent in the storage chamber. If the judgment results are all "yes", that is, if there is a designated user in the set area and there is a laundry treatment agent in the storage chamber, the electromagnetic switch is turned on. If the judgment result is "no", that is, if there is no designated user in the set area or there is no laundry treatment agent in the storage chamber, the electromagnetic switch is not turned on. In addition, when the alarm signal emitted by the detection device is not received, that is, when the remaining amount does not meet the preset condition, it indicates that the laundry treatment agent in the dispensing device is sufficient, and there is no need to turn on the electromagnetic switch.
