Description

Technical Field

[0001] This application relates to the field of home appliance technology, and more specifically, to a household appliance. Background Technology

[0002] With the advancement of the times, people's requirements for home appliances have gradually increased. Some home appliances that can hold items (such as refrigerators, dishwashers, or ovens) are usually equipped with door locking functions to lock the door and the body of the appliance, preventing children from opening the door of the appliance in case of accidents, and improving safety performance.

[0003] Traditional household appliances typically use mechanical locks on the door to secure it to the appliance. However, these mechanical locks usually require a key to unlock, which is inconvenient. With technological advancements, some household appliances have incorporated screen button locks. However, these screen button locks require a significant amount of space on the front of the door, disrupting the door's aesthetics and creating a sense of unity. Utility Model Content

[0004] The purpose of this application is to provide a household appliance that addresses the technical problem that the appearance of doors equipped with screen button locks is significantly affected in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a household appliance, comprising:

[0006] The fuselage has a receiving cavity and a first opening communicating with the receiving cavity;

[0007] A door body is movably connected to the body and is used to open or close the first opening; the door body has a first side side, which is located on the side of the door body away from the receiving cavity when the door body closes the first opening;

[0008] A handle assembly is installed on the first side of the door body. The handle assembly has an installation groove on one side in a first direction, and the first direction is parallel to the first side.

[0009] A locking assembly includes a first locking part and a second locking part, wherein the first locking part is installed on the body and the second locking part is installed on the door body; the locking assembly has a locking position and an unlocking position, wherein in the locking position, the first locking part and the second locking part are connected; and in the unlocking position, the first locking part and the second locking part are separated.

[0010] A button is installed in the mounting slot, and pressing the button allows the lock assembly to switch between the locked position and the unlocked position.

[0011] According to the above technical solution, by setting a button to control the lock assembly to switch between the locked and unlocked positions, the connection or separation of the first and second locking parts is controlled, thereby controlling the locking and unlocking between the door and the machine body. This simple operation improves user convenience. Furthermore, by creating a mounting groove on one side of the handle assembly in the first direction, the button is embedded in the groove, effectively protecting the integrity of the door body and, to a certain extent, concealing the button installation. This reduces the impact on both the door's appearance and the handle assembly's appearance.

[0012] In one possible design, the handle assembly includes:

[0013] A mounting base is installed on the first side.

[0014] The handle body is mounted on the fixed base;

[0015] The mounting groove is provided on one side of the fixed base or the handle body in the first direction.

[0016] According to the above technical solution, on the one hand, since the handle body is for the user to hold, when the mounting groove is set on the handle body, it is convenient for the user to press the button. On the other hand, since the fixing seat is installed on the first side, that is, the fixing seat is connected to the door body, when the mounting groove is set on the fixing seat, the button is installed on the fixing seat, so as to control the lock assembly to switch between the locked position and the unlocked position by pressing the button.

[0017] In one possible design, there are multiple fixing seats, which are spaced apart and installed on the first side. The handle body is connected to each of the multiple fixing seats, and at least one fixing seat has a mounting groove on one side in the first direction.

[0019] In one possible design, each of the mounting bases has a mounting groove on one side in the first direction, and the button is mounted in the mounting groove on any of the mounting bases.

[0020] According to the above technical solution, by opening mounting slots on each fixed base, the installation position of the buttons can be adjusted according to the user's actual needs, thereby improving user satisfaction.

[0021] In one possible design, the household appliance further includes a contouring structure whose shape is the same as at least a portion of the shape of the button. The button is installed in the mounting slot on one of the plurality of mounting bases, and the contouring structure is installed in the mounting slots on the other mounting bases respectively.

[0022] According to the above technical solution, by setting a contoured structure with the same shape as the button in the mounting slot where no button is installed, it is beneficial to improve the aesthetics and at the same time reduce the entry of dust and other impurities into the mounting slot where no button is installed, thereby improving hygiene and cleanliness.

[0023] In one possible design, the household appliance further includes a control module and a drive module. The control module is signal-connected to the button and the drive module, respectively. One of the first locking part and the second locking part is connected to the drive module. The control module is used to receive control signals sent by the button, and the control module is also used to control the drive module to drive the lock assembly to switch between the locked position and the unlocked position according to the control signals.

[0024] According to the above technical solution, by setting up a control module and a drive module, the button can control the lock component to switch between the locked position and the unlocked position through signal control.

[0025] In one possible design, the button is a touch button, which is used to send the control signal to the control module after being triggered.

[0026] According to the above technical solution, users can control the locking and unlocking of the door and the machine body simply by touching a button, making the operation more convenient.

[0027] In one possible design, the button includes a movable part, an elastic part, and an excitation part. The excitation part is mounted on the bottom wall of the mounting groove. The movable part is slidably mounted on the mounting groove along the first direction. The elastic part is located between the bottom wall of the mounting groove and the movable part. The excitation part is triggered by pressing the movable part. The excitation part is used to send the control signal to the control module after being triggered.

[0028] According to the above technical solution, the locking and unlocking of the door and the machine body can be controlled by pressing the button, which is convenient to operate.

[0029] In one possible design, the bottom wall of the mounting groove is provided with a guide cylinder, and the movable part is provided with a guide post on the side facing the bottom wall of the mounting groove, the guide post being inserted into the guide cylinder.

[0030] According to the above technical solution, with the cooperation of the guide cylinder and the guide column, the movable part can move along a predetermined direction when it is pressed, so that the movable part can accurately trigger the excitation part, resulting in higher reliability.

[0031] In one possible design, the handle assembly is provided with an indicator light, which is signal-connected to the control module, and the control module is used to control the light color of the indicator light according to the control signal.

[0032] According to the above technical solution, the control module controls the light color of the indicator light according to the control signal, so that the user can judge the current connection status of the door and the machine body according to the light color of the indicator light.

[0049] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0050] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0051] It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0053] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0054] like Figure 1 As shown, one embodiment of this application provides a household appliance, including a body, a door 100, a handle assembly 200, a lock assembly, and buttons 400. Optionally, the household appliance provided in this embodiment can be a refrigerator, oven, or dishwasher, etc.

[0055] The fuselage has a receiving cavity and a first opening communicating with the receiving cavity. The receiving cavity is used to place items (such as food or tableware), and the first opening is used to allow items to enter and exit the receiving cavity.

[0056] The door 100 is movably connected to the body and is used to open or close the first opening. By covering the first opening with the door 100, the first opening is closed to protect the items inside the receiving cavity. Optionally, the movable connection between the door 100 and the body may include, but is not limited to, a hinged connection, a sliding connection, and a detachable connection.

[0057] like Figure 1 As shown, the door 100 has a first side surface 120. When the door 100 closes the first opening, the first side surface 120 is located on the side of the door 100 away from the receiving cavity. In the embodiments of this application, the first side surface 120 can be a horizontal plane, a vertical plane, or an inclined plane. For ease of description, the following description will use a vertical first side surface 120 as an example.

[0058] Please see Figure 1 and Figure 2 The handle assembly 200 is installed on the first side 120 of the door body 100. The handle assembly 200 has a mounting groove 260 on one side surface in the first direction, which is parallel to the first side 120. Optionally, the first direction can be a vertical direction, a horizontal direction, or any inclined direction parallel to the first side 120.

[0059] The handle assembly 200 is used by a user to grip and drive the door body 100 to move relative to the body, thereby opening or closing the first opening. The handle assembly 200 can be installed on the first side 120 by means of snap-fit, welding, bonding or auxiliary connectors (such as screws).

[0060] The lock assembly includes a first locking part and a second locking part. The first locking part is mounted on the main body, and the second locking part is mounted on the door 100. The lock assembly has a locked position and an unlocked position. In the locked position, the first locking part and the second locking part are connected; in the unlocked position, the first locking part and the second locking part are separated. Optionally, one of the first locking part and the second locking part can be a bolt, and the other can be a lock groove. When the lock assembly is in the locked position, the bolt is inserted into the lock groove, and the inner wall of the lock groove limits the bolt, thereby locking the door 100 to the main body and effectively reducing the possibility of the door 100 being accidentally opened. When the lock assembly is in the unlocked position, the bolt retracts from the lock groove, thereby releasing the limitation on the bolt and allowing the door 100 to move relative to the main body, so that the user can open the first opening when needed.

[0061] The button 400 is installed in the mounting slot 260. Pressing the button 400 allows the lock assembly to switch between the locked and unlocked positions. Optionally, the button 400 can be a mechanical button 400 or an electronic button 400. When the button 400 is a mechanical button 400, it can be connected to the lock assembly via a mechanical connection. For example, the first locking part is a lock groove, the second locking part is a lock tongue, and the button 400 is connected to the lock tongue via a connecting rod. When the button 400 is pressed, the connecting rod causes the lock tongue to insert or retract from the lock groove, thereby switching the lock assembly between the locked and unlocked positions. When the button 400 is an electronic button 400, it can be connected to the lock assembly via an electronic control method. For example, the household appliance also includes a control module, and the button 400 is connected to the lock assembly via the control module. When the button 400 is pressed, the control module controls the lock assembly to switch between the locked and unlocked positions.

[0062] The household appliance provided in this application embodiment controls the locking assembly to switch between a locked position and an unlocked position via a button 400, thereby controlling the connection or separation of the first locking part and the second locking part, and thus controlling the locking and unlocking between the door 100 and the appliance body. This simple operation improves user convenience. Furthermore, by creating a mounting groove 260 on one side of the handle assembly 200 in the first direction, the button 400 is embedded in the mounting groove 260, effectively protecting the integrity of the door 100 and, to a certain extent, concealing the button 400. This reduces the impact on the appearance of both the door 100 and the handle assembly 200.

[0063] In one possible design, such as Figure 3As shown, the handle assembly 200 includes a fixing seat 210 and a handle body 230. The fixing seat 210 is mounted on the first side 120, and the handle body 230 is mounted on the fixing seat 210. The fixing seat 210 or the handle body 230 has the aforementioned mounting groove 260 on one side in the first direction.

[0064] In one example, the mounting base 210 has a mounting groove 260 on one side in the first direction, and the button 400 is installed in the mounting groove 260 on the mounting base 210. Since the mounting base 210 is installed on the first side 120, that is, the mounting base 210 is connected to the door body 100, when the mounting groove 260 is set on the mounting base 210, the button 400 is installed on the mounting base 210. With this configuration, when the button 400 is a mechanical button 400, it is convenient for the button 400 to be connected to the second locking part, thereby facilitating the switching of the lock assembly between the locked position and the unlocked position by pressing the button 400. When button 400 is an electronic button 400, a circuit structure for signal connection with the electronic button 400 is also required so that pressing button 400 can control the lock assembly to switch between the locked and unlocked positions. Since the space on the mounting base 210 and the handle body 230 is limited, the circuit structure can be set on the door body 100. Since button 400 is installed in the mounting slot 260 on the mounting base 210, it is convenient for button 400 to be connected to the circuit structure on the door body 100, thereby facilitating the switching of the lock assembly between the locked and unlocked positions by pressing button 400.

[0065] In another example, the handle body 230 has the aforementioned mounting groove 260 on one side surface in the first direction. In this embodiment, the handle body 230 is used for a user to hold, and the button 400 is installed in the mounting groove 260 on the handle body 230 so that the user can press the button 400.

[0066] Optionally, the handle body 230 can be made of metal to improve its structural strength and service life. Alternatively, such as... Figure 3 As shown, the handle body 230 has a strip-shaped structure to facilitate user grip. Optionally, as... Figure 4 As shown, the handle body 230 can be configured as a hollow structure, which reduces the material consumption of the handle body 230 and lowers the cost.

[0067] Optionally, the mounting base 210 can be connected to the handle body 230 of the door 100 by screws or clips. In one example, such as Figures 5 to 7As shown, the handle assembly 200 also includes a fixing post 240, a first screw 270, and a second screw 280. A slot 213 is provided on the side of the fixing base 210 facing the door body 100, and a through hole 214 is provided on one side wall of the slot 213. One end of the handle body 230 is inserted into the slot 213 through the through hole 214. The fixing post 240 is inserted into the slot 213 through the opening of the slot 213 until it contacts the handle body 230. A first threaded hole 241 is provided on the side of the fixing post 240 facing the door body 100. A first through hole 110 is provided through the door body 100 along its thickness direction. The first screw 270 passes through the first through hole 110 and is threadedly connected to the first threaded hole 241. The first threaded hole 241 is a blind hole structure. A second through hole 242 is provided through the bottom wall of the first threaded hole 241. The handle body 230 is provided with a second threaded hole 231. The second screw 280 passes through the second through hole 242 and is threadedly connected to the second threaded hole 231.

[0068] In one possible design, such as Figure 3 As shown, there are multiple fixing seats 210, which are installed at intervals on the first side 120. The handle body 230 is connected to each of the multiple fixing seats 210, and at least one fixing seat 210 has a mounting groove 260 on one side in the first direction. It should be noted that when two or more fixing seats 210 are provided with mounting grooves 260, the button 400 is installed in the mounting groove 260 of one of the fixing seats 210. By providing multiple fixing seats 210, the installation stability of the handle body 230 is improved.

[0069] In one example, there are two fixing seats 210, and both ends of the handle body 230 are connected to the two fixing seats 210 respectively. In another example, there may be three fixing seats 210, with both ends of the handle body 230 connected to two of the fixing seats 210 respectively, and the third fixing seat 210 disposed between the two fixing seats 210 and connected to the handle body 230.

[0070] For ease of description, the following text will refer to the number of fixed seats 210 as two, such as Figure 3 As shown, one of the fixing seats 210 is the first fixing seat 211, and the other fixing seat 210 is the second fixing seat 212. The two ends of the handle body 230 are connected to the first fixing seat 211 and the second fixing seat 212 respectively for illustration.

[0071] In some embodiments, the first fixing base 211 and the second fixing base 212 are spaced apart along a second direction, which is parallel to the first side surface 120. Optionally, the second direction may be parallel to the first direction or may be at an angle to the first direction.

[0072] Taking a horizontal direction parallel to the first side 120 as an example, the second direction can be a vertical direction, and at least one of the first fixing seat 211 and the second fixing seat 212 can have a mounting groove 260 on its upper or lower side. In another example, the first direction can also be parallel to the second direction; the mounting groove 260 is provided on the side of the first fixing seat 211 and the second fixing seat 212 that is close to or away from the other, or the mounting groove 260 is provided on the sides of the first fixing seat 211 and the second fixing seat 212 that are close to or far from each other.

[0073] In one possible design, each mounting base 210 has a mounting slot 260 on one side in the first direction, and the button 400 is installed in the mounting slot 260 on any of the mounting bases 210. By providing mounting slots 260 on each mounting base 210, the installation position of the button 400 can be adjusted according to the user's actual needs, thereby improving user satisfaction.

[0074] In one specific example, the first and second directions are set in parallel. For example... Figure 3 and 8 As shown, mounting slots 260 are respectively provided on the opposite sides of the first fixing seat 211 and the second fixing seat 212, and the button 400 is installed in one of the mounting slots 260.

[0075] In one possible design, such as Figure 8 As shown, the household appliance also includes a contoured structure 250, the shape of which is identical to at least a portion of the shape of the button 400. The button 400 is installed in a mounting slot 260 on one of the plurality of mounting bases 210, while the contoured structure 250 is installed in the mounting slots 260 on the other mounting bases 210. According to this arrangement, by providing a contoured structure 250 with the same shape as the button 400 in the mounting slot 260 where the button 400 is not installed, the aesthetics are improved, and dust and other impurities are reduced from entering the mounting slot 260 where the button 400 is not installed, thus improving cleanliness.

[0076] In this embodiment, the mounting groove 260 has a bottom wall opposite its opening and a peripheral side wall surrounding the outer periphery of the bottom wall. The button 400 has a pressing portion, which is mounted within the mounting groove 260 and protrudes through the opening of the mounting groove 260. The pressing portion is used for pressing by a user. In this embodiment, the shape of the contouring structure 250 is at least the same as the shape of the pressing portion of the button 400.

[0077] In one specific embodiment, such as Figure 3 and Figure 8As shown, the button 400 is installed in the mounting groove 260 on the first fixed base 211, and the contour structure 250 is installed in the mounting groove 260 on the second fixed base 212.

[0078] In one possible design, the household appliance further includes a control module and a drive module. The control module is signal-connected to both the button 400 and the drive module, and one of the first locking part and the second locking part is connected to the drive module. The control module receives control signals sent by the button 400 and also controls the drive module to switch the lock assembly between the locked and unlocked positions based on the control signals. It should be noted that in this embodiment, the signal connection can be via a wireless communication module (e.g., a Bluetooth module or an infrared wireless module), or via a cable or other structure capable of transmitting data signals. By setting up the control module and the drive module, the button 400 can control the lock assembly to switch between the locked and unlocked positions via signal control.

[0079] Specifically, the drive module has a first drive position and a second drive position, and the control module is used to control the drive module to switch between the first drive position and the second drive position. When the drive module switches to the first drive position, the drive module drives the lock component to switch to the locked position, and when the drive module switches to the second drive position, the drive module drives the lock component to switch to the unlocked position.

[0080] In one implementation, each time the control module receives a control signal from button 400, it controls the drive module to switch its drive position once. That is, if the drive module is currently in the first drive position (lock assembly is in the locked position), when the control module receives the control signal from button 400, it controls the drive module to switch to the second drive position, so that the lock assembly switches to the unlocked position; conversely, if the drive module is currently in the second drive position (lock assembly is in the unlocked position), when the control module receives the control signal from button 400, it controls the drive module to switch to the first drive position, so that the lock assembly switches to the locked position.

[0081] Optionally, the drive module can be installed on the machine body or on the door 100. In one example, the drive module is installed on the machine body and connected to the first locking part. The drive module is used to drive the first locking part to move relative to the machine body, so that the first locking part can be connected or disconnected from the second locking part. When the drive module is installed on the door 100, the drive module is connected to the second locking part and is used to drive the second locking part to move relative to the door 100, so that the first locking part can be connected or disconnected from the second locking part.

[0082] In a specific example, such as Figure 3As shown, the household appliance also includes a circuit board 300. The circuit board 300, the control module, and the drive module are all installed on the door 100. The circuit board 300 is electrically connected to the control module, the drive module, and the button 400, respectively. The control module is signal connected to the drive module and the button 400 through the circuit board 300.

[0083] Optionally, the drive module may include a motor or an electromagnet. In one example, the drive module includes a motor mounted on the door body 100, a second locking part being a latch, a first locking part being a lock groove, and the output end of the motor being connected to the latch. The control module controls the motor to drive the latch to extend into or move out of the lock groove, thereby controlling the lock assembly to switch between the locked and unlocked positions.

[0084] In one possible design, button 400 is a touch button 400, which sends a control signal to the control module after being triggered. In this configuration, the user can unlock the door 100 simply by pressing button 400, making operation more convenient.

[0085] In one possible design, such as Figure 9 As shown, button 400 includes a movable part 410, an elastic part 420, and an excitation part 430. The excitation part 430 is mounted on the bottom wall of the mounting groove 260. The movable part 410 is slidably mounted on the mounting groove 260 along a first direction. The elastic part 420 is located between the bottom wall of the mounting groove 260 and the movable part 410. Pressing the movable part 410 triggers the excitation part 430, which sends a control signal to the control module after being triggered. It can be understood that in this embodiment, the movable part 410 is the pressing part of button 400, and the excitation part 430 is signal-connected to the control module. Pressing the movable part 410 triggers the excitation part 430, causing the excitation part 430 to send a control signal to the control module, thereby controlling the locking and unlocking of the door 100 and the machine body, making operation convenient. When the movable part 410 is pressed until the triggering part 430 is activated, the elastic part 420 is compressed and stores energy. When the movable part 410 is released, the elastic part 420 rebounds and releases energy to push the movable part 410 back to its original position. Optionally, the elastic part 420 can be a spring, a rubber part, or other elastic structure, and is not limited to any particular type.

[0086] In one possible design, such as Figure 4 As shown, a guide cylinder 261 is provided on the bottom wall of the mounting groove 260; as Figure 10 As shown, a guide post 411 is provided on the side of the movable part 410 facing the bottom wall of the mounting groove 260, and the guide post 411 is inserted into the guide cylinder 261. With the cooperation of the guide cylinder 261 and the guide post 411, the movable part 410 can move in a predetermined direction when pressed, so that the movable part 410 can accurately trigger the excitation part 430, and the reliability is higher.

[0087] In one specific embodiment, such as Figure 9 As shown, the mounting base 210 has a receiving groove 215 on the side facing the door 100. The receiving groove 215 and the slot 213 are spaced apart along the first direction. A protrusion 216 is provided on the inner wall of the receiving groove 215 away from the slot 213. The mounting groove 260 on the mounting base 210 extends from one side of the mounting base 210 in the first direction into the protrusion 216. A through hole is provided through the bottom wall of the mounting groove 260, which communicates with the inner hole of the guide cylinder 261. Part of the structure of the excitation part 430 is located in the receiving groove 215, and another part of the structure is inserted into the guide cylinder 261 through the through hole, so that the excitation part 430 is stably installed on the bottom wall of the mounting groove 260. In this arrangement, the circuit board 300 and the excitation part 430 can be electrically connected by a cable. The cable connecting the circuit board 300 and the excitation part 430 can pass through the opening of the receiving groove 215 to facilitate the electrical connection between the circuit board 300 and the excitation part 430.

[0088] In one possible design, a limiting portion is provided in the mounting groove 260 to limit the maximum distance that the movable part 410 can move away from the bottom wall of the mounting groove 260. In this arrangement, after the movable part 410 moves a predetermined distance away from the bottom wall of the mounting groove 260, it contacts the limiting portion, effectively reducing the possibility of the movable part 410 falling out of the mounting groove 260. In one example, a limiting portion protrudes from the peripheral sidewall of the mounting groove 260, spaced apart from the bottom wall, with the movable part 410 located between the limiting portion and the bottom wall of the mounting groove 260.

[0089] In one possible design, the handle assembly 200 is equipped with an indicator light, which is signal-connected to a control module. The control module controls the indicator light's illumination color according to the control signal. For example, the indicator light can emit at least two different colors of light; when the drive module is in a first drive position (indicating the lock assembly is in the locked position), the control module controls the indicator light to emit one color of light; when the drive module is in a second drive position (the lock assembly is in the unlocked position), the control module controls the indicator light to emit the other color of light. This allows the user to determine the current connection status between the door body 100 and the main body based on the indicator light's illumination color.

[0090] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
