[0056] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0057] In order to better understand the technical solutions of the present application, the following will be described in detail in conjunction with the accompanying drawings of the specification and the specific implementation manners.

[0058] The main solution of the embodiment of the present application is: The household appliance includes a first main body; a second main body, installed on the first main body, the second main body having a receiving cavity with one end open; a cover body, movably installed on the opening for opening or closing the opening; a driving mechanism for driving the movement of the cover body; a contact detection device including a first detection part and a second detection part, the first detection part is arranged on the first main body, the second detection part is arranged on the second main body, the first detection part and the second detection part are used to detect whether the user touches the surfaces of the first main body and the second main body; a control device arranged on the first main body; a control unit, electrically connected to the control device, the driving mechanism and the contact detection device, and the control unit is used to control the driving mechanism to work according to the contact detection device and the control device.

[0059] In this embodiment, for the convenience of description, the household appliance is taken as the execution subject for elaboration below.

[0060] Electric shavers currently on the market usually have a cavity at the bottom or top for collecting beard debris after shaving, and users open this cavity for cleaning through a physical button switch. However, this design has a problem: when the user accidentally presses the button, the storage cavity will suddenly open, causing the beard debris to scatter everywhere, seriously affecting the user experience.

[0061] This application provides a solution that can ensure that the user opens the cavity when actively opening the accommodating cavity, reduces the misoperation rate, avoids the leakage of the materials loaded in the cavity, reduces unnecessary troubles, ensures the convenience and safety of use, and improves the user experience.

[0062] Based on this, an embodiment of this application provides a household appliance, such as Figure 1 shown Figure 1 is a schematic structural diagram of the household appliance. The household appliance includes a first main body; a second main body installed on the first main body, the second main body having an accommodating cavity with one end open; a cover movably installed on the opening for opening or closing the opening; a driving mechanism for driving the cover to move; a contact detection device including a first detection part and a second detection part, the first detection part is arranged on the first main body, the second detection part is arranged on the second main body, and the first detection part and the second detection part are used to detect whether the user touches the surfaces of the first main body and the second main body; a control device arranged on the first main body; and a control device electrically connected to the control device, the driving mechanism and the contact detection device, and the control device is used to control the driving mechanism to work according to the contact detection device and the control device.

[0063] It should be noted that the first main body includes a holding part in this embodiment, or may not include a special holding part. When there is no special holding part, the first main body can be used as the part held by the user. The inside of the first main body can include a microprocessor for controlling the electrical functions and other devices, and this embodiment does not limit this. In this embodiment, when the user holds the first main body and the second main body at the same time, the household appliance can be kept stable. When there is a separately provided holding part on the first main body, the first detection part also exists on the holding part.

[0064] It can be understood that the second main body refers to the storage cavity part of the household appliance, which has an accommodating cavity with one end open and can be used for the waste materials after the household appliance works, such as beard debris generated after the shaver works, and fabric debris generated after the hair clipper works.

[0065] In a specific implementation, the household appliance further includes a cover body, which is movably installed at the opening of the second main body and is used to open or close the accommodation cavity. When the cover body is opened, the accommodation cavity is opened, and at this time, the waste materials existing in the accommodation cavity can be cleaned; when the cover body is closed, the accommodation cavity is closed, and at this time, the waste materials existing in the accommodation cavity can be prevented from spilling out.

[0066] It should be noted that the driving mechanism is used to drive the movement of the cover body. The driving mechanism can control the opening of the cover body or limit the opening of the cover body.

[0067] It can be understood that the contact detection device includes a first detection part and a second detection part. There is at least one skin sensor in both the first detection part and the second detection part. The skin sensor can be an infrared sensor, a capacitance sensor or other skin detection sensors. The first detection part and the second detection part are respectively arranged on the first main body and the second main body. The first detection part is used to detect whether the user contacts the surface of the first main body, and the second detection part is used to detect whether the user contacts the surface of the second main body. In this embodiment, the first detection part is arranged on the surface of the first main body, and at the same time, the second detection part is arranged on the surface of the second main body to ensure the accuracy of user contact detection.

[0068] In a specific implementation, the control device is arranged on the first main body. When the user operates the control device, the cover body is opened; when the driving mechanism restricts the opening of the cover body, when the operating device is operated, the cover body cannot be opened. In this embodiment, the control device may include operation keys arranged on the surface of the first main body. The operating device may also be arranged at other positions to achieve the above functions, and this embodiment does not limit this.

[0069] It should be noted that the control device may be located inside the first main body. In this embodiment, the control device may be composed of a microprocessor such as a single-chip microcomputer. The control device is electrically connected to the driving structure, the control device and the contact detection device. After the contact detection device detects that the user contacts the surfaces of the first main body and the second main body and the user operates the control device, at this time, the control device controls the driving mechanism to work and opens the cover body.

[0070] In a feasible implementation manner, as Figure 2 shown, the household appliance further includes a displacement detection device. The control device is also electrically connected to the displacement detection device. The control device is further used to control the driving mechanism to work according to the displacement detection device and the contact detection device.

[0071] It should be noted that the displacement detection device can be an acceleration sensor. The displacement detection device is used to detect whether the user is using the household appliance. The control device is electrically connected to the displacement detection device. When it is detected by the displacement detection device that the user is using the household appliance and it is detected by the contact detection device that the user is simultaneously contacting the first main body and the second main body, when it is detected that the control device is operated at this time, the control drive mechanism works to open the cover body; or, when it is detected by the displacement detection device that the user is using the household appliance and it is detected by the contact detection device that the user is not simultaneously contacting the first main body and the second main body, when it is detected that the control device is operated at this time, the control drive mechanism works to prevent the cover body from being opened.

[0072] In a feasible implementation manner, a locking structure is provided between the cover body and the second main body. The locking structure includes a locking portion provided on one of the cover body and the second main body, and a matching portion provided on the other. The locking portion is movably provided so as to have a locking position fixedly matched with the matching portion and an unlocking position disengaged from the matching portion during its movement stroke; the drive mechanism includes: a limiting portion movably provided so as to have a limiting position for limiting the locking portion at the locking position and a releasing position for releasing the limitation on the locking portion; and a driving portion for driving the limiting portion to switch from the limiting position to the releasing position; wherein, the control device is electrically connected to the driving portion for controlling the driving portion to work.

[0073] It should be noted that the locking structure is used to lock the cover body to prevent it from being accidentally opened. The locking structure includes a locking portion and a matching portion. A part of the locking structure exists on the cover body, and another part of the locking structure exists on the second main body. The locking portion can move. When the locking portion and the matching portion are fixedly matched, the cover body is locked on the second main body, and the waste materials in the accommodating cavity cannot be scattered. At this time, the position where the locking portion cooperates with the matching portion on the second main body is the locking position. When the locking portion is not cooperating with the matching portion, that is, when the cover body is opened, the materials in the accommodating cavity can be cleaned. At this time, the position where the locking portion is located after disengaging from the matching portion is the unlocking position. In this embodiment, the locking portion and the matching portion can be a buckle and a slot, or other locking structures, and this embodiment does not limit this.

[0074] It can be understood that the limiting portion in the drive mechanism can also move. The limiting portion can limit the locking portion at the locking position. At this time, the position where it is located is the limiting position, and the cover body cannot be opened; when the limiting portion is located at the releasing position, the limitation on the locking portion is released, and at this time the cover body can be opened; that is, in this embodiment, when the limiting portion is in the limiting position, the normal use of the control device can be restricted, and even if the control device is operated, the cover body cannot be opened.

[0075] It should be noted that the driving part in the driving structure is electrically connected to the control device. The control device can control the operation of the driving part. The driving part can drive the limiting part to switch from the limiting position to the releasing position or drive the limiting part to switch from the releasing position to the limiting position according to the instructions of the control device.

[0076] In a specific implementation, taking a household appliance as an electric shaver as an example for illustration, its structure is as Figure 3 shown. The holding part is the first main body; the cavity part is the second main body; the cutter head is located below the second main body; the key switch is the control device and is located below the cavity; the skin sensor is located on the surfaces of the cavity and the holding part; the acceleration sensor is located inside the shaver; the control device is located inside the holding part, and the control flow of the control device is as Figure 4 shown. When an acceleration change (i.e., the device moves) is detected, it is identified whether the skin sensor of the current holding part is triggered. If it is not triggered, it means that the current is a non-user active behavior; if it is triggered, it means that the current is a user active behavior, and then it is further determined whether the skin sensor of the cavity part is triggered. If it is not triggered, the microprocessor restricts the key switch through the driving mechanism so that it cannot be normally opened, preventing the beard in the cavity from being accidentally spilled. If it is triggered, the control device (i.e., the microprocessor) releases the restriction on the key switch through the driving mechanism so that it can be opened by the user by pressing to clean the cavity.

[0077] In this embodiment, a household appliance is provided. The household appliance includes a first main body; a second main body installed on the first main body, the second main body having a receiving cavity with one end open; a cover body movably installed on the opening for opening or closing the opening; a driving mechanism for driving the cover body to move; a contact detection device including a first detection part and a second detection part, the first detection part is arranged on the first main body, the second detection part is arranged on the second main body, the first detection part and the second detection part are used to detect whether the user touches the surfaces of the first main body and the second main body; a control device arranged on the first main body; a control device electrically connected to the control device, the driving mechanism and the contact detection device, and the control device is used to control the driving mechanism to work according to the contact detection device and the control device. By the above method, it can be ensured that the user opens the cavity when actively opening the receiving cavity, reducing the misoperation rate, avoiding the leakage of the materials loaded in the cavity, reducing unnecessary troubles, ensuring the convenience and safety of use, and improving the user experience.

[0078] This application also provides a control method for a household appliance, referring to Figure 5 , Figure 5 is a schematic flowchart of the first embodiment of the control method for the household appliance of this application.

[0079] The control method of the household appliance is applied to the control device of the household appliance described above. The household appliance includes a first main body, a second main body, a cover body, a driving mechanism, a contact detection device, and a control device. The second main body has a receiving cavity with one end open, and the cover body is used to open or close the opening. The contact detection device includes a first detection part provided on the first main body and a second detection part provided on the second main body.

[0080] In this embodiment, the control method of the household appliance includes steps S10 to S20:

[0081] Step S10: When there is a first contact signal in the first detection data collected by the first detection part, obtain the second detection data collected by the second detection part.

[0082] It should be noted that the execution subject of this embodiment is the control device of the household appliance. The first detection part is located on the surface of the first main body. When there is a separately provided holding part on the first main body, the first detection part is located on the surface of the holding part. The first detection data collected by the first detection part may or may not contain a signal of the user actively contacting the surface of the first main body (for example, there is no contact signal, or a signal of the user accidentally touching the surface of the first main body). In this embodiment, the first contact signal refers to the signal of the user actively contacting the surface of the first main body, and the first detection part and the second detection part are skin sensors.

[0083] It can be understood that when there is a first contact signal in the first detection data, it means that the user has contacted the holding part of the household appliance. At this time, obtain the second detection data collected by the second detection part. In this embodiment, the second detection part is provided on the surface of the receiving cavity of the second main body and is used to detect whether the user actively contacts the storage cavity part.

[0084] In a feasible implementation manner, after step S10, steps A11 to A13 are further included:

[0085] Step A11: Determine the continuous contact duration of the user according to the second detection data.

[0086] It should be noted that the second detection data refers to the real-time signal data collected by the second detection part and is used to detect whether the user contacts the surface of the storage cavity. Analyze the second detection data to determine the time length that the user keeps in contact with the surface of the second main body (that is, the surface of the storage cavity), so as to ensure the authenticity of the operation intention. In this embodiment, the continuous contact duration refers to the time length that the user continuously keeps in contact with the surface of the second main body of the household appliance.

[0087] Step A12: When the continuous contact duration exceeds the preset duration, determine that there is a second contact signal in the second detection data.

[0088] It should be noted that the preset duration is a preset time length used to distinguish effective contact from accidental contact. In this embodiment, the preset duration can be set to 5s, or can be set to other values according to requirements, and this embodiment does not limit this. When the continuous contact duration exceeds the preset duration, it indicates that the user is actively contacting the surface of the second body at this time, and the contact with the surface of the second body is determined as an effective contact. At this time, it is determined that there is a second contact signal in the second detection data.

[0089] Step A13: When the continuous contact duration does not exceed the preset duration, determine that there is no second contact signal in the second detection data.

[0090] It should be noted that when the continuous contact duration does not exceed the preset duration, it indicates that the user may accidentally touch the surface of the second body, or does not touch the surface of the second body at all. At this time, it is determined that there is no second contact signal in the second detection data.

[0091] Step S20: When there is a second contact signal in the second detection data and an unlocking instruction sent through the control device is received, control the driving mechanism to drive the cover to move.

[0092] It should be noted that when there is a signal of the user actively contacting the surface of the second body in the second detection data, it indicates that the user is holding the first body and the second body at the same time. At this time, opening the cover of the accommodation cavity will not cause the material to spill out. The user operates the control device, indicating that an unlocking instruction to open the cover of the accommodation cavity is initiated. At this time, it is determined as the user's active behavior, which will also prevent the material in the accommodation cavity from spilling out, and the control device controls the driving mechanism to drive the cover to open.

[0093] In a feasible implementation manner, the driving mechanism includes a limiting part and a driving part. In step S20: controlling the driving mechanism to drive the cover to move can further include steps B11 - B12:

[0094] Step B11: When the current position is the limiting position, generate a release instruction. The limiting position is the position where the locking part is limited to the locking position. The locking position is the fixed cooperation position between the locking part and the cooperating part. A locking structure is provided between the cover and the second body. The locking structure includes a locking part provided on one of the cover and the second body, and a cooperating part provided on the other.

[0095] It should be noted that the limiting part in the driving mechanism can also move. The limiting part can limit the locking part in the locking position, and the position at this time is the limiting position, and the cover body cannot be opened; when the limiting part is in the release position, the limitation of the locking part is released, and the cover body can be opened at this time; that is, in this embodiment, when the limiting part is in the limiting position, the normal use of the control device can be restricted, and even if the control device is operated, the cover body cannot be opened.

[0096] It can be understood that the driving part in the driving structure is electrically connected to the control device. The control device can control the operation of the driving part. The driving part can drive the limiting part to switch from the limiting position to the release position, or drive the limiting part to switch from the release position to the limiting position according to the instruction of the control device.

[0097] In a specific implementation, the locking structure is used to lock the cover body to prevent it from being accidentally opened. The locking structure includes a locking part and a matching part. A part of the locking structure exists on the cover body, and another part of the locking structure exists on the second main body. The locking part can move. When the locking part and the matching part are fixedly matched, the cover body is locked on the second main body, and the waste materials in the accommodating cavity cannot be spilled. At this time, the position where the locking part cooperates with the matching part on the second main body is the locking position. When the locking part is not matched with the matching part, that is, the cover body is opened, the materials in the accommodating cavity can be cleaned. At this time, the position where the locking part is located after disengaging from the matching part is the unlocking position.

[0098] Step B12: Send the release instruction to the driving part so that the driving part switches the current position of the limiting part to the release position according to the release instruction. The release position is the position after the limitation of the locking part is released.

[0099] It should be noted that when the user initiates an unlocking instruction, the control device needs to judge whether the limiting part is in the release position. When it is in the release position, the locking part can move within the moving stroke. At this time, when the user operates the control device, the cover body is normally driven to open; when the limiting part is in the limiting position, it means that the cover body cannot be opened normally at this time. The control device needs to generate a release instruction and send this instruction to the driving part. After receiving this instruction, the driving part switches the current position of the limiting part to the release position. At this time, the unlocking instruction initiated by the user is responded to, and the cover body is driven to open.

[0100] In this embodiment, when a first contact signal exists in the first detection data collected by the first detection unit, the second detection data collected by the second detection unit is obtained; when a second contact signal exists in the second detection data and an unlocking instruction sent through the control device is received, the driving mechanism is controlled to drive the cover to move. By the above method, it can be ensured that the user opens the cavity when actively opening the accommodation cavity, reducing the misoperation rate, avoiding the spillage of the materials loaded in the cavity, reducing unnecessary troubles, ensuring the convenience and safety of use, and improving the user experience.

[0101] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar content as that in the above-mentioned first embodiment can be referred to the above introduction and will not be elaborated hereinafter. On this basis, please refer to Figure 6 , Figure 6 which is a schematic flowchart of the second embodiment of the control method for household appliances of the present application.

[0102] In this embodiment, the driving mechanism includes a limiting part and a driving part; for the control method of the household appliance, after the step S10, the steps S01 to S03 are further included:

[0103] Step S01: When the second contact signal does not exist in the second detection data, obtain the current position of the limiting part.

[0104] It should be noted that when the second contact signal does not exist in the second detection data, it indicates that the user is not holding the first main body and the second main body at the same time. At this time, opening the cover of the accommodation cavity will cause the materials to spill out. The operation of the user on the control device can be recognized as a misoperation and determined as the accidental touch behavior of the user. In order to limit the function of the control device and prevent the cover from being opened, the current position of the limiting part is obtained.

[0105] Step S02: When the current position is the release position, a limiting instruction is generated. The release position is the position after the locking part is released from the limit. A locking structure is provided between the cover and the second main body. The locking structure includes a locking part provided on one of the cover and the second main body and a matching part provided on the other.

[0106] Step S03: Send the limiting instruction to the driving part so that the driving part switches the current position of the limiting part to the limiting position according to the limiting instruction. The limiting position is the position where the locking part is limited to the locked position.

[0107] It should be noted that when the limiting part is in the limiting position, the cover cannot be opened. That is, even if the user wants to open the cover through the control device, the cover will remain closed due to the locking part being limited.

[0108] It is understandable that when the limiting part is in the release position, in order to avoid responding to the unlocking instruction (i.e., restricting the function of the control device) and keep the cover closed, the control device needs to generate a limiting instruction and send this instruction to the driving part. After receiving this instruction, the driving part then switches the current position of the limiting part to the limiting position.

[0109] In this embodiment, when there is no second contact signal in the second detection data, the current position of the limiting part is obtained; when the current position is the release position, a limiting instruction is generated, where the release position is the position after the locking part is released from the limit, and a locking structure is provided between the cover and the second main body. The locking structure includes a locking part provided on one of the cover and the second main body, and a matching part provided on the other; the limiting instruction is sent to the driving part so that the driving part switches the current position of the limiting part to the limiting position according to the limiting instruction, and the limiting position is the position where the locking part is limited to the locked position. By the above method, the misoperation rate is reduced and the user experience is improved.

[0110] Based on the above embodiments of the present application, in the third embodiment of the present application, the same or similar content as in the above Embodiment 1 can be referred to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 7 , Figure 7 which is a schematic flow chart of the second embodiment of the control method for household appliances of the present application.

[0111] In this embodiment, for the control method of the household appliance, before step S10, steps S11 to S12 are further included:

[0112] Step S11: Obtain the current motion data collected by the displacement detection device.

[0113] It should be noted that in order to avoid loss, a displacement detection device is also provided in the household appliance. The displacement detection device can be an acceleration sensor and is used to detect the motion state of the household appliance (such as whether it is picked up or other user's active operation behaviors). In this embodiment, the current motion data refers to the motion state data of the household appliance collected by the displacement detection device in real time, and the current motion data includes data such as the acceleration, angular velocity, tilt angle, and moving direction of the household appliance.

[0114] In a feasible implementation manner, after step S11, steps C11 to C12 can further be included:

[0115] Step C11: Determine the device tilt angle and the device moving direction according to the current motion data.

[0116] It should be noted that the device tilt angle refers to the angle of the household appliance relative to the horizontal plane; the device movement direction refers to the movement trend or path of the household appliance in space, which is usually related to the user's active operation behavior (such as picking up).

[0117] It can be understood that by analyzing the current motion data of the displacement, the device tilt angle and the device movement direction of the household appliance are determined, and the two are combined to further determine whether there is a user's active operation behavior for the household appliance (such as being picked up and used by the user).

[0118] Step C12: When the device tilt angle is within a preset operation range and the device movement direction is a preset operation direction, it is determined that there is a device operation signal in the current motion data.

[0119] It should be noted that the preset operation range refers to the preset tilt angle range; the preset operation direction refers to the preset movement direction. Both the preset operation range and the preset operation direction can be set according to the user's usage habits, and the specific angle range and specific movement direction are not limited in this embodiment.

[0120] It can be understood that when the device tilt angle is within the preset operation range and the device movement direction is the preset operation direction, it is determined that the household appliance is picked up by the user or there is other active operation behavior, and the user is using the household appliance. At this time, it is determined that there is a device operation signal in the current motion data. In this embodiment, the device operation signal refers to the motion signal indicating that the user is using the household appliance.

[0121] Step S12: When there is a device operation signal in the current motion data, obtain the first detection data collected by the first detection unit.

[0122] It should be noted that when there is a device operation signal in the current motion data, it means that the household appliance is being used by the user. At this time, obtain the first detection data collected by the first detection unit and perform subsequent contact detection and drive control processes.

[0123] It can be understood that after obtaining the first detection data collected by the first detection unit, further contact detection is performed to determine whether the user contacts the surface of the first main body. Specifically: analyze the first detection data to determine the time length of the user's contact with the surface of the first main body, so as to ensure the authenticity of the operation intention. When the time length of the user's contact with the surface of the first main body exceeds the preset duration, it is determined that there is a first contact signal in the first detection data. It is also possible to analyze the first detection data in other ways to determine whether there is a first contact signal in the first detection data, and this embodiment does not limit this.

[0124] In this embodiment, the current motion data collected by the displacement detection device is obtained; when there is a device operation signal in the current motion data, the first detection data collected by the first detection unit is obtained. In the above manner, after the displacement detection device detects the user's usage intention, the subsequent process is entered, which increases the intelligence and responsiveness of the system, reduces the system power consumption, and prolongs the service life of the product.

[0125] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the control method of household appliances in this application.
