Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, specifically to household appliances. Background Technology

[0002] Current household appliances, such as cooking utensils, unlock their lids by pushing a mechanical button, which is then released by a hinge spring. When users are holding a bowl and spoon in both hands, they need to use one hand to push the button, which is inconvenient and reduces the user experience. Utility Model Content

[0003] In view of this, this application provides a household appliance to solve the technical problem that existing household appliances are inconvenient to open.

[0004] In a first aspect, this application provides a household appliance, comprising: a housing having a receiving space and an opening; a cover being closably disposed at the opening of the housing for opening or closing the receiving space; and a locking mechanism including a locking assembly and a sensing element communicatively connected to the locking assembly, the locking assembly being disposed in the household appliance for locking or releasing the cover, the locking assembly being configured to release the cover according to a sensing signal from the sensing element.

[0005] Beneficial effects: The household appliance proposed in this application uses a sensing element to detect user signals, and then the locking mechanism can open the cover according to the user signals detected by the sensing element, thereby solving the technical problem that users need to free their hands to open the cover and improving the user experience.

[0006] Specifically, home appliances are equipped with sensing elements for human-computer interaction. These sensing elements can convert the user's voice or gesture signals into electrical signals. After the electrical signals are transmitted to the home appliance, the control lock component unlocks the cover, allowing the cover to be opened without manual operation by the user, thus improving the user's operating experience.

[0007] In one alternative embodiment, the lock assembly includes a lock hook disposed on the cover, a lock body disposed on the housing, and a drive device, wherein the lock hook is configured to engage or disengage the lock body, and the drive device is configured to drive the lock hook to disengage the lock body according to a sensing signal.

[0008] Beneficial effects: The locking hook is rotatably mounted on the cover via an elastic reset member. Under the elastic force of the reset member, the locking hook locks onto the lock body, thus securing the cover to the housing. When the user needs to unlock the cover, they only need to input a sensing signal to the sensing element. The drive device can then drive the locking hook to release the lock body based on the sensing signal, thereby unlocking the cover. The lock assembly of this embodiment, through the cooperation of the drive device, sensing element, and elastic reset member, achieves the purpose of opening and closing the cover. It is convenient to operate, requiring no manual operation from the user, thus improving the user experience.

[0009] In one alternative embodiment, the locking hook is rotatably mounted on the cover, and the driving device includes a solenoid valve and a push rod assembly that cooperates with the solenoid valve. The solenoid valve drives the locking hook to release the lock body through the push rod assembly.

[0010] Beneficial effects: The solenoid valve can drive the push rod assembly to move up and down through electromagnetic induction signals, thereby releasing the unlocking and locking components and opening the cover. Compared with motors, hydraulic mechanisms and pneumatic mechanisms, the solenoid valve has the advantages of simple structure, small space occupation and fast response speed.

[0011] In one alternative embodiment, the push rod assembly includes a vertical push rod and a lever structure. The vertical push rod is configured to engage with the input end of the lever structure via a pushing ramp, and the output end of the lever structure can drive the locking hook to rotate during rotation.

[0012] Beneficial effects: By cooperating with the pushing ramp of the lever structure, the vertical movement of the drive device can be converted into the lateral or circumferential movement of the lever structure. This allows the push rod assembly to push the locking hook horizontally to unlock the cover. Furthermore, placing the drive device vertically improves its spatial adaptability and reduces the horizontal space it occupies on household appliances.

[0013] In one optional embodiment, two vertical push rods are provided, which are connected by a connecting plate. The middle of the connecting plate is provided with a T-slot that mates with the valve stem of the solenoid valve, and two guide posts are provided on both sides of the connecting plate.

[0014] Beneficial effects: By applying two vertical push rods to the lever structure, the thrust balance between the vertical push rods and the lever structure can be improved, reducing the phenomenon of one end tilting caused by uneven stress distribution between the vertical push rods and the lever structure.

[0015] In one optional embodiment, a mounting bracket is provided on the inner side of the housing, a snap-fit ​​groove that mates with the valve body of the solenoid valve is provided in the middle of the mounting bracket, a limiting rib that mates with the valve body is provided on the inner wall of the housing, and two guide sleeves that mate with two guide posts are provided on both sides of the mounting bracket.

[0016] Beneficial effects: Positioning and fixing the solenoid valve using the mounting bracket and limiting ribs improves its operational stability and reduces vertical displacement or lateral wobbling during the operation of the vertical push rod. Guiding the two guide posts with two guide sleeves allows for synchronized vertical movement, reducing the likelihood of misalignment during this process.

[0017] In one alternative embodiment, the input end of the lever structure is provided with a pressing plate, the pressing plate is provided with a raised button, the housing is provided with a button hole that mates with the button, and the button is exposed outside the housing through the button hole.

[0018] Beneficial effects: The household appliance of this application automatically opens its lid by controlling the lid with a sensor signal. At the same time, it retains the original mechanical lid opening structure of the household appliance, which allows the lid to be opened manually even in the event of a power outage, thus improving the reliability of the household appliance.

[0019] In one alternative embodiment, the output end of the lever structure is provided with two spaced-apart bent levers that bend inward toward the interior of the housing, and a pressing plate spans and connects the two bent levers, with the distribution direction of the pressing plate being consistent with the distribution direction of a portion of the housing at the button hole.

[0020] Beneficial effects: The press plate not only provides installation space for the button, but also, through its cooperation with two bent levers, evenly transmits the user's pressing force to the locking hook, thereby reducing uneven pressure between the lever structure and the locking hook. The two spaced-apart bent levers also provide room for the button's movement, reducing interference between the bent levers and the button or its surrounding structure.

[0021] In one alternative embodiment, the sensing element includes a voice sensor, a gesture sensor, an expression sensor, or a touch sensor, the sensing element is disposed in the housing, and the housing is provided with an opening for exposing the sensing element.

[0022] Beneficial effects: By using voice sensors or posture sensors, only the user's voice signals, posture signals, facial expression signals, or touch signals need to be sensed. For example, the user can control the drive device to unlock the cover by nodding or raising a foot signal, thus eliminating the need for the user to open the cover manually and improving the user experience.

[0023] In one alternative embodiment, the sidewall of the housing is connected to the bottom of the housing via an arcuate structure, and the sensing element is disposed on the curved portion of the arcuate structure in the direction of the receiving space.

[0024] Beneficial effects: By placing the sensing element in the curved part of the arc structure towards the receiving space, the sensing element is hidden, reducing the risk of the exposed sensing element being easily damaged by accident.

[0025] In one alternative embodiment, the curved portion is provided with a through hole, and the household appliance also includes a storage compartment disposed in the through hole, the storage compartment including a honeycomb cover located outside the through hole and an open slot located inside the through hole.

[0026] Beneficial effects: The placement chamber and honeycomb cover of the placement chamber can serve to assemble and protect the sensing element. In addition, the honeycomb cover can also serve to collect sound, thereby improving the working sensitivity and response speed of the sensing element.

[0027] In one alternative embodiment, the honeycomb cover extends into the inside of the through hole and is located inside the housing. The bottom two side walls of the open slot are provided with two snap-fit ​​holes, and the two side walls of the sensing element are provided with two buckles that snap into the two snap-fit ​​holes.

[0028] Beneficial effects: By concealing the honeycomb cover inside the housing, the risk of damage from impacts is reduced, and the accumulation of external dust, debris, or water can also be minimized, preventing clogging of the cover. The sensing element is detachably mounted to the open slot via a snap-fit ​​mechanism, facilitating both the installation and maintenance of the sensing element and the honeycomb cover, thus reducing the likelihood of malfunctions in either the sensing element or the honeycomb cover.

[0029] In one alternative embodiment, the household appliance further includes a pot body disposed in the receiving space, and a locking mechanism disposed between the pot body and the housing.

[0030] Beneficial effects: Placing the locking mechanism between the pot body and the outer shell can improve the spatial adaptability of the locking mechanism and reduce the space occupied by the locking mechanism in the cooking space of the household appliance.

[0031] In one alternative embodiment, the household appliance includes a rice cooker, with a housing configured as the rice cooker body and a lid configured as the rice cooker lid, one side of the lid being rotatably connected to the rice cooker body via an elastic component.

[0032] Beneficial effects: One side of the lid is rotatably connected to the rice cooker body via an elastic component, allowing the lid to automatically open under the elastic force of the component. When the user needs to unlock the lid, they simply input a sensing signal to the sensing element, and the drive device will then activate the locking hook to release the lock body, allowing the lid to automatically open under the elastic force of the component. This process eliminates the need for manual operation, improving the user experience. Attached Figure Description

[0060] The following is combined Figures 1 to 16 This describes an embodiment of the present application.

[0061] like Figures 1 to 10 As shown, according to an embodiment of this application, in one aspect, this application provides a household appliance 100, which includes a housing 10, a cover 20, and a locking mechanism. The housing 10 is provided with a receiving space and an opening. The cover 20 is closably disposed at the opening of the housing 10 for opening or closing the receiving space. The locking mechanism includes a locking assembly 30 and a sensing element 40 communicatively connected to the locking assembly 30. The locking assembly 30 is disposed on the household appliance 100 for locking or releasing the cover 20. The locking assembly 30 is configured to release the cover 20 according to the sensing signal of the sensing element 40.

[0062] In this embodiment, the household appliance 100 proposed in this application uses the user signal sensed by the sensing element 40, and then the locking mechanism can open the cover 20 according to the user signal sensed by the sensing element 40, thereby solving the technical problem that the user needs to free up their hands to open the cover and improving the user experience.

[0063] Specifically, the household appliance 100 includes cooking appliances and cleaning appliances, etc. For ease of explanation, the household appliance 100 of this application will be described below using cooking appliances as an example. The household appliance 100 is equipped with a sensing element 40 for human-computer interaction. The sensing element 40 can convert the user's voice signal or posture signal into an electrical signal. After the electrical signal is transmitted to the household appliance 100, the control lock assembly 30 unlocks the cover 20, so that the cover 20 can be opened without the user's manual operation, thereby improving the user's operating experience.

[0064] It should be noted that the embodiments of this application do not limit the specific structure of the lock assembly 30 and the sensing element 40, because the main improvement of this application is to achieve the technical effect of automatically controlling the lock assembly 30 through the sensing signal of the sensing element 40. As for the specific structure of the lock assembly 30 and the sensing element 40, it can be set according to the type of the lock assembly 30 and the sensing element 40 and the actual use environment. For example, the lock assembly 30 can be set as a snap-fit ​​structure, a bolt structure or a latch structure, etc., and the sensing element 40 can be set as a voice sensing, posture signal or image signal, etc. These adjustments are all within the protection scope of the embodiments of this application.

[0065] The following is through Figures 1 to 16 The embodiments described herein illustrate preferred embodiments of the specific structures of the lock assembly 30 and the sensing element 40.

[0066] like Figures 1 to 9 As shown, in some embodiments, the lock assembly 30 includes a lock hook 34 disposed on the cover 20, a lock body 35 disposed on the housing 10, and a drive device 31. The lock hook 34 is configured to engage or disengage the lock body 35, and the drive device 31 is configured to drive the lock hook 34 to disengage the lock body 35 according to a sensing signal.

[0067] In the above embodiment, the locking hook 34 is rotatably disposed on the cover by an elastic reset member. The locking hook 34 can be locked to the lock body 35 under the elastic force of the elastic reset member, thereby achieving the purpose of locking the cover 20 to the housing 10. When the user needs to unlock the cover 20, he only needs to input a sensing signal to the sensing element 40, and the driving device 31 can drive the locking hook 34 to release the lock body 35 according to the sensing signal, thereby achieving the purpose of unlocking the cover 20.

[0068] The lock assembly 30 in this embodiment of the application can achieve the purpose of opening and closing the cover 20 through the cooperation of the drive device 31, the sensing element 40 and the elastic reset member. It is easy to operate and the user does not need to operate manually, which improves the user experience.

[0069] like Figures 1 to 9As shown, in some embodiments, the locking hook 34 is rotatably mounted on the cover 20, and the driving device 31 includes a solenoid valve and a push rod assembly that cooperates with the solenoid valve. The solenoid valve drives the locking hook 34 to release the lock body 35 through the push rod assembly.

[0070] In this embodiment, the solenoid valve can drive the push rod assembly to move up and down through electromagnetic induction signals, thereby releasing the unlocking and locking assembly 30 and opening the cover 20. Compared with motors, hydraulic mechanisms and pneumatic mechanisms, the solenoid valve has the advantages of simple structure, small space occupation and fast response speed.

[0071] The base of housing 10 has a surrounding rib at the mounting position of the solenoid valve to fix the circumference of the solenoid valve. The base of housing 10 also has a supporting rib at the mounting position of the solenoid valve to support the bottom of the solenoid valve. The base of housing 10 has a latch at the mounting position of the solenoid valve to fix the vertical position of the solenoid valve to the base.

[0072] like Figures 1 to 9 As shown, in some embodiments, the push rod assembly includes a vertical push rod 32 and a lever structure 33. The vertical push rod 32 is configured to cooperate with the input end of the lever structure 33 through a pushing inclined surface 321. The output end of the lever structure 33 can push the locking hook 34 to rotate during rotation.

[0073] In the above embodiment, by cooperating with the pushing slope 321 of the lever structure 33, the vertical movement of the drive device 31 can be converted into the lateral or circumferential movement of the lever structure 33, thereby enabling the push rod assembly to push the locking hook 34 in the horizontal direction to unlock the cover 20. In addition, placing the drive device 31 vertically can improve the spatial adaptability of the drive device 31 and reduce the horizontal space occupied by the drive device 31 in the household appliance 100.

[0074] like Figures 1 to 9 As shown, in some embodiments, there are two vertical push rods, which are connected by a connecting plate 322. The middle part of the connecting plate 322 is provided with a T-slot 323 that cooperates with the valve stem of the solenoid valve, and two guide posts 324 are provided on both sides of the connecting plate 322.

[0075] In the above embodiment, by having two vertical push rods 32 act on the lever structure 33, the thrust balance between the vertical push rods 32 and the lever structure 33 can be improved, and the phenomenon of one end deflection caused by uneven stress distribution between the vertical push rods 32 and the lever structure 33 can be reduced.

[0076] Specifically, the vertical push rod 32 has a T-slot 323 for connecting to the output end of the solenoid valve to achieve vertical movement. The mounting position of the solenoid valve has two guide holes, which cooperate with the two guide posts 324 of the vertical push rod 32 to restrict the vertical movement of the vertical push rod 32 and maintain smooth movement. The top of the vertical push rod 32 is provided with a sloped structure, which serves as a moving contact surface to push the lever structure 33 to open the locking hook 34 by rotation.

[0077] like Figures 1 to 9 As shown, in one optional embodiment, a mounting bracket 12 is provided on the inner side of the housing, a snap-fit ​​groove 121 that mates with the valve body of the solenoid valve is provided in the middle of the mounting bracket 12, a limiting rib 111 that mates with the valve body is provided on the inner wall of the housing, and two guide sleeves 122 that mate with two guide posts 324 are provided on both sides of the mounting bracket 12.

[0078] In the above embodiments, the solenoid valve is positioned and fixed by the mounting bracket 12 and the limiting rib 111, which can improve the working stability of the solenoid valve and reduce the phenomenon of vertical displacement or left-right swaying during the process of the solenoid valve driving the vertical push rod 32. By guiding the two guide sleeves 122 to guide the two guide posts 324, the two guide posts 324 can move up and down synchronously, reducing the phenomenon of skewness of the two guide posts 324 during the up and down movement.

[0079] like Figures 1 to 9 As shown, in some embodiments, the input end of the lever structure 33 is provided with a pressing plate 331, the pressing plate 331 is provided with a raised button 36, the housing 10 is provided with a button hole that mates with the button 36, and the button 36 is exposed outside the housing 10 through the button hole.

[0080] In the above embodiment, the household appliance 100 controls the automatic opening of the cover 20 via a sensing signal. At the same time, retaining the original mechanical opening structure of the household appliance 100 allows for manual opening even during power outages, improving the operational reliability of the household appliance 100.

[0081] Furthermore, the press plate 331 is also provided with a trigger switch 332, which can send the pressing action of the button 36 to the home appliance 100, thereby enabling the home appliance 100 to adjust the corresponding cooking operation.

[0082] like Figures 1 to 9 As shown, in an optional embodiment, the output end of the lever structure 33 is provided with two spaced-apart bent levers 330 that bend toward the interior of the housing 10. The pressing plate 331 spans and connects the two bent levers 330, and the distribution direction of the pressing plate 331 is consistent with the distribution direction of part of the housing 10 at the button hole.

[0083] In the above embodiment, the pressing plate 331 not only provides installation space for the button 36, but also, through its cooperation with the two bent levers 330, evenly transmits the user's pressing force to the locking hook 34, thereby reducing the phenomenon of uneven pressure between the lever structure 33 and the locking hook 34. The two spaced-apart bent levers 330 also provide movement space for the button 36, reducing interference between the bent levers 330 and the button 36 or the surrounding structure of the button 36.

[0084] like Figures 10 to 16 As shown, in some embodiments, the sensing element 40 includes a voice sensor, a posture sensor, an expression sensor, or a touch sensor. The sensing element 40 is disposed in the housing 10, and the housing 10 is provided with an opening for exposing the sensing element 40.

[0085] In this embodiment, the voice sensor or posture sensor only needs to sense the user's voice signal, posture signal, facial expression signal or touch signal. For example, the user can control the drive device 31 to drive the lock assembly 30 to unlock the cover 20 through a nodding signal or foot lifting signal. Similarly, the user does not need to open the cover manually, which improves the user experience.

[0086] The voice sensor includes a microphone. The base of the housing 10 is equipped with snap-fit ​​holes, and snap-fits are provided on the left and right sides of the microphone for fixing and installing the microphone.

[0087] like Figures 10 to 16 As shown, in some embodiments, the sidewall of the housing 10 is connected to the bottom of the housing 10 via an arcuate structure 11, and the sensing element 40 is disposed on the curved portion of the arcuate structure 11 in the direction of the receiving space.

[0088] In this embodiment, by placing the sensing element 40 on the curved portion of the arc structure 11 in the direction of the receiving space, the sensing element 40 is hidden, reducing the risk of the sensing element 40 being exposed and easily damaged by accident.

[0089] like Figures 10 to 16 As shown, in some embodiments, the curved portion is provided with a through hole, and the household appliance 100 also includes a storage compartment 42 disposed in the through hole. The storage compartment 42 includes a honeycomb cover 41 located outside the through hole and an open groove 43 located inside the through hole.

[0090] In this embodiment, the placement chamber 42 and the honeycomb cover 41 can serve to assemble and protect the sensing element 40. In addition, the honeycomb cover 41 can also serve to receive sound, thereby improving the working sensitivity of the sensing element 40 and increasing the response speed of the sensing element 40.

[0091] like Figures 10 to 16As shown, in an optional embodiment, the honeycomb cover 41 extends into the inside of the through hole and is located inside the housing 10. The bottom two side walls of the open groove 43 are provided with two snap-fit ​​holes 431, and the two side walls of the sensing element 40 are provided with two buckles that snap into the two snap-fit ​​holes 431.

[0092] In this embodiment, by concealing the honeycomb cover 41 inside the housing 10, the risk of the honeycomb cover 41 being damaged by impact can be reduced, and the phenomenon of external dust, debris, or water adhering and clogging the honeycomb cover 41 can also be reduced. The sensing element 40 is detachably installed to the open slot 43 by snap-fit, which not only facilitates the disassembly and maintenance of the sensing element 40, but also facilitates the disassembly and maintenance of the honeycomb cover 41, reducing the possibility of malfunctions of the sensing element 40 or the honeycomb cover 41.

[0093] like Figures 10 to 16 As shown, in some embodiments, the household appliance 100 also includes a pot body disposed in the receiving space, and a locking mechanism is disposed between the pot body and the housing 10.

[0094] In this embodiment, the locking mechanism is located between the pot body and the shell 10, which can improve the spatial adaptability of the locking mechanism and reduce the space occupied by the locking mechanism in the cooking space of the household appliance 100.

[0095] like Figures 10 to 16 As shown, in some embodiments, the household appliance 100 includes a rice cooker, with a housing 10 serving as the rice cooker body and a lid 20 serving as the rice cooker lid, one side of which is rotatably connected to the rice cooker body via an elastic component 21.

[0096] In this embodiment, one side of the lid is rotatably connected to the rice cooker body via an elastic component 21. The lid can automatically open the rice cooker under the elastic force of the elastic component 21. When the user needs to unlock the lid, they only need to input a sensing signal to the sensing element 40, and the driving device 31 can drive the locking hook 34 to release the locking body 35 according to the sensing signal, and the lid can then automatically open the rice cooker under the elastic force of the elastic component 21. During this process, the user does not need to operate manually, improving the user experience.

[0097] like Figure 1 As shown, specifically, the rice cooker consists of two parts: a lid and a cooker body. The cooker body is equipped with a microphone to capture ambient sound signals. These sound signals are converted into electrical signals and transmitted to the control unit 50. The control unit 50 receives the sound signals and sends signals to the solenoid valve drive lock assembly 30 via voice recognition technology to unlock the lid. The lid is rotatably mounted to the cooker body via a hinge spring, with the long arm of the hinge spring located on the lid for opening it.

[0098] like Figure 2As shown, when the lid is closed, the hinge spring is compressed; Figure 3 As shown, when the solenoid valve drives the push rod upward to unlock the lever structure 33 and the locking hook 34, the hinge spring can pop up and open the pot lid.

[0099] like Figures 4-7 As shown, when the solenoid valve drives the push rod upward to unlock the lever structure 33 and the locking hook 34, the lever structure 33 rotates at a certain angle to push the locking hook 34 open.

[0100] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
