Description
Technical Field
[0001] This invention relates to the field of kitchen appliance technology, and more particularly to a dishwasher. Background Technology
[0002] As a common cleaning appliance in modern homes and commercial kitchens, one of the core functions of dishwashers is to remove moisture from the surface of tableware through a high-temperature drying stage to achieve a fast and thorough cleaning effect. During the drying process, a large amount of high-temperature, high-humidity water vapor is generated inside the sealed cavity. This vapor easily condenses repeatedly on the inner wall of the dishwasher drum and the surface of the tableware, forming water droplets and causing the tableware to become damp again, which seriously affects the drying effect.
[0003] To address the issue of insufficient moisture removal and incomplete drying in a closed drying mode, dishwashers need to partially open the door during the drying stage to achieve efficient drying through air convection. Currently, most dishwashers rely on automatic door locks to open and close the door automatically. These automatic door locks typically employ motor drives and complex mechanical linkages, which not only increase manufacturing costs but also raise the failure rate.
[0004] Therefore, there is an urgent need for a simple, low-cost method that can effectively solve the problem of moisture retention during the drying stage, in order to improve and optimize the drying performance of dishwashers. Summary of the Invention
[0005] This invention provides a dishwasher to solve the technical problems of complex structure and high manufacturing cost of automatic opening and closing of dishwasher doors.
[0006] To achieve the above objectives, the present invention provides a dishwasher, including a body and a door, wherein the door is hinged to the body, and the dishwasher further includes:
[0007] A movable component, which is movably disposed on the body along a first direction;
[0008] A door lock assembly is disposed on the door body, and the door lock assembly cooperates with the moving member to cause the moving member to drive the door body to move;
[0009] A driving structure, comprising a first driving component and a second driving component, wherein the first driving component and the second driving component apply forces to the moving member in opposite directions, and the first driving component is configured to change the magnitude of the driving force on the moving member when the temperature changes.
[0010] In response to the temperature of the first drive component being greater than or equal to a preset temperature, the drive structure drives the moving part to move from a first position to a second position, so that the moving part drives the door to switch from a closed state to an open state to discharge water vapor;
[0011] In response to the temperature of the first driving component being lower than a preset temperature, the driving structure drives the moving member to move from the second position to the first position, so that the moving member drives the door to switch from the open state to the closed state.
[0012] The dishwasher provided in this application has a dual-drive system, which includes a first drive component and a second drive component. The change in the driving force of the first drive component on the moving parts is triggered by temperature, so that the door can automatically open during the high-temperature drying stage to enhance moisture removal and automatically close during the cooling stage to restore the seal. This not only reduces the dependence on additional motors, complex transmission components and manual operation, but also matches the opening and closing timing with the changes in thermal state, thereby improving dehumidification efficiency and drying effect.
[0013] Furthermore, by using the moving part to perform linear reciprocating motion along the first direction, the structure of the drive structure and the door lock assembly is relatively simple, the overall number of parts is small, the assembly and maintenance complexity is reduced, and the cooperation between the first drive assembly and the second drive assembly can stably constrain the movement stroke of the moving part, which is beneficial to improving the consistency and reliability of the door opening and closing action.
[0014] In one possible implementation, in response to the first drive component exerting a greater driving force on the movable member than the second drive component exerting a greater force on the movable member, the first drive component drives the movable member to move from a second position to a first position, so that the movable member drives the door to switch from an open state to a closed state.
[0015] In response to the first driving component exerting a driving force on the moving member being less than the second driving component exerting a force on the moving member, the second driving component drives the moving member to move from a first position to a second position, so that the moving member drives the door to switch from a closed state to an open state.
[0016] In one possible implementation, the first driving component includes:
[0017] A first magnetic component is disposed on the body;
[0018] A second magnetic element is connected to the moving part. At least one of the first and second magnetic elements is a temperature-sensitive magnetic element with a Curie temperature point higher than the temperature of the washing water in the dishwasher. The first and second magnetic elements are positioned opposite each other to generate a magnetic force between the body and the moving part.
[0019] In one possible implementation, the first magnetic element is a temperature-sensitive magnetic element, and the second magnetic element is a permanent magnet.
[0020] In one possible implementation, the dishwasher further includes: a guide structure disposed in the body, the guide structure having a guide groove extending along the first direction, the first magnetic element disposed in the guide groove, one end of the movable element extending into the guide groove, the guide groove being used to guide the movement of the movable element.
[0021] In one possible implementation, the sidewall of the moving member has a stop protrusion, and the second drive assembly includes:
[0022] A limiting baffle is provided on the machine body, and the limiting baffle has a clearance hole inside for the moving part to pass through;
[0023] An elastic sleeve is fitted around the outer periphery of the movable member, and the two ends of the elastic sleeve abut against the stop protrusion and the limiting baffle, respectively.
[0024] In one possible implementation, the door lock assembly includes a linkage member movably disposed on the door body in a second direction, and the movable member having a locking hook at one end facing the door body, the locking hook having a locking groove.
[0025] When the moving member moves along the first direction, the locking hook pushes the linkage member along the second direction to switch the linkage member and the locking hook between a hooked state and a released state; wherein, in the hooked state, the linkage member is located in the locking groove, and the end of the locking hook facing the door body abuts against the door body; in the released state, the linkage member disengages from the locking groove.
[0026] In one possible implementation, the linkage has a first guide surface and a second guide surface on opposite sides, respectively;
[0027] When the moving member moves closer to the door body along the first direction, the outer wall of the locking hook abuts against the first guide surface to guide the linkage member to move away from the locking hook along the second direction;
[0028] When the moving member moves away from the door body along the first direction, the inner wall of the locking hook abuts against the second guide surface to guide the linkage member to move away from the locking hook along the second direction.
[0029] In one possible implementation, the bottom end of the first guide surface is flush with the bottom end of the second guide surface, and the tilt angle of the first guide surface is greater than the tilt angle of the second guide surface relative to the first direction.
[0030] In one possible implementation, the door has a limiting step, the linkage and the limiting step are spaced apart along the second direction, and the door lock assembly further includes an elastic member located between the linkage and the limiting step, with both ends of the elastic member connected to the linkage and the limiting step, respectively.
[0031] Along the second direction, the direction in which the elastic member applies force to the linkage member is opposite to the direction in which the moving member drives the linkage member to move.
[0032] In one possible implementation, the dishwasher further includes a heating unit and a control unit. The heating unit is disposed on the top of the machine body and corresponds to the position of the temperature-sensing magnetic element. The heating unit is used for drying heating and heating the temperature-sensing magnetic element. The control unit is electrically connected to the heating unit.
[0033] When the door switches from the closed state to the open state, the control unit controls the heating unit to stop heating.
[0034] The dishwasher provided by this invention has a heating unit located at the top of the machine body. The heating area of the heating unit corresponds to the position of the temperature-sensing magnetic component, allowing heat to be transferred to the temperature-sensing magnetic component along a shorter path, thereby improving thermal response efficiency. The heating unit not only heats the tableware and moisture in the washing chamber during the drying stage, but also thermally excites the temperature-sensing magnetic component, causing it to change its magnetic state and drive the first drive assembly to operate after reaching a preset temperature.
[0035] The dishwasher provided by this invention utilizes the influence of temperature changes on the driving force and combines the synergistic effect of dual drive components in opposite directions to achieve automatic switching of the door's opening and closing state according to the temperature during the drying process. It transforms the linear motion of the moving parts into the locking and unlocking actions of the door lock component, eliminating the need for additional complex independent drives. This achieves coordination between the opening and closing of the door and the drying cycle, thereby reducing structural complexity and improving the overall effect of dehumidification and safety.
[0036] The dishwasher provided by this invention has a guide groove in the guide structure that forms positional and orientation constraints on the moving parts. Under the guidance of the guide structure, the moving parts are always in a controllable guiding state within the stroke, avoiding problems such as swaying, shaking, and jamming of the moving parts during the door opening and closing linkage.
[0037] The dishwasher provided by this invention has a first guide surface that is the contact side of the moving part when it approaches the door in the first direction, and a second guide surface that is the contact side of the moving part when it moves away from the door in the first direction. The bottom end of the first guide surface is flush with the bottom end of the second guide surface. The tilt angle of the first guide surface is greater than that of the second guide surface relative to the first direction, so that the first guide surface and the second guide surface are differentiated in height and tilt angle. The contact process of the locking hook in the two directions is respectively characterized by a rapid entry into the hooking state and a gradual entry into the releasing state, thereby improving the stability and consistency of the automatic opening and closing action of the whole machine.
[0038] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions as described above, other technical problems that can be solved by a dishwasher provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific embodiments.

[0083] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0084] The dishwasher's operation typically includes washing, rinsing, and drying stages. After washing and rinsing, it enters the drying stage.
[0085] During the drying stage, the dishwasher's inner drum generates high-temperature airflow through the heating and fan modules to accelerate the evaporation of moisture from the tableware surface. However, due to the poor thermal conductivity of ceramic tableware, its surface temperature is usually higher than the inner drum temperature, causing the evaporated water vapor to condense on the inner wall of the drum, forming water droplets. After the drying stage ends, the inner drum temperature gradually decreases, and the condensed water droplets drip back onto the tableware surface, causing secondary dampness and severely affecting the drying effect. This not only leads to insufficient drying and water stains on the surface but also makes the washing chamber a damp environment for a long time, which in turn breeds bacteria, produces odors, and affects the hygiene of the tableware.
[0086] Therefore, during the drying stage, the dishwasher needs to continuously heat and ventilate within a relatively enclosed inner drum space to promote the evaporation of moisture from the surface of the tableware. It should also be able to open and close the door in a timely manner according to temperature changes during the drying process, so as to balance dehumidification efficiency and safety.
[0087] Current dishwashers mostly use continuous heating combined with fan circulation during the drying stage to accelerate the evaporation of moisture from the tableware surface. However, under the relatively sealed conditions of the inner drum, the evaporated water vapor is prone to condensation on the cooler inner wall or door area, and then falls back onto the tableware surface, causing secondary dampness and directly reducing the drying effect.
[0088] To address the issue of moisture retention, related technologies employ motor-driven automatic door opening structures, using electronic control systems to regulate door opening and closing. While this achieves automation, it typically requires additional drive motors, transmission components, and control logic, resulting in complex structures, high assembly costs, and reliability issues due to component wear, jamming, or control mismatches during long-term operation. Especially in dishwasher drying conditions, door opening and closing must be synchronized with temperature changes and dehumidification rhythms. Relying solely on conventional electronic control methods not only increases energy consumption and maintenance burdens but also makes it difficult to simultaneously achieve structural economy, safety, and drying efficiency.
[0089] In view of this, this application proposes an improvement solution to address the problems of moisture retention and condensation during the drying process of existing dishwashers, secondary moisture reabsorption, the possibility of burns from manual door opening, and the complex, costly, and unreliable structure of automatic door opening by motors.
[0090] This application specifically provides a dishwasher. Since the drive structure includes a first drive component and a second drive component, it realizes dual drive. The change of the driving force of the first drive component on the moving parts needs to be triggered by temperature, so that the door can automatically open during the high temperature drying stage to enhance the removal of moisture and automatically close during the cooling stage to restore the seal. This not only reduces the dependence on additional motors, complex transmission components and manual operation, but also matches the opening and closing timing with the change of thermal state. It can improve the dehumidification efficiency and improve the drying effect while ensuring the safety of use.
[0091] A dishwasher provided by an embodiment of the present invention is described below with reference to the accompanying drawings.
[0092] refer to Figure 1 and Figure 2 As shown, this application embodiment provides a dishwasher, including a body 10 and a door 20. The door 20 is hinged to the body 10. The dishwasher also includes a moving member 30, a door lock assembly 40, and a drive structure. The moving member 30 is movably disposed on the body 10 along a first direction; the door lock assembly 40 is disposed on the door 20, and the door lock assembly 40 cooperates with the moving member 30 to cause the moving member 30 to drive the door 20 to move. (Reference) Figure 3 , Figure 4 and Figure 5 As shown, the drive structure includes a first drive component 50 and a second drive component 60. The first drive component 50 and the second drive component 60 apply forces to the moving member 30 in opposite directions. The first drive component 50 is configured to change the magnitude of the driving force on the moving member 30 when the temperature changes.
[0093] When the temperature of the first drive component 50 is greater than or equal to a preset temperature, the drive structure drives the moving part 30 to move from the first position to the second position, so that the moving part 30 drives the door 20 to switch from the closed state to the open state to discharge water vapor.
[0094] When the temperature of the first drive component 50 is lower than the preset temperature, the drive structure drives the moving part 30 to move from the second position to the first position, so that the moving part 30 drives the door 20 to switch from the open state to the closed state.
[0095] This application provides a dishwasher whose drive structure includes a first drive component 50 and a second drive component 60, achieving dual drive. The change in the driving force of the first drive component 50 on the moving part 30 is triggered by temperature, so that the door 20 can automatically open during the high-temperature drying stage to enhance moisture removal and automatically close during the cooling stage to restore the seal. This not only reduces the dependence on additional motors, complex transmission components and manual operation, but also matches the opening and closing timing with changes in thermal state, which can improve dehumidification efficiency and improve drying effect while ensuring safety of use.
[0096] Furthermore, since the moving part 30 performs linear reciprocating motion along the first direction, the structure of the drive structure and the door lock assembly 40 is relatively simple, with fewer parts, reducing the complexity of assembly and maintenance. Moreover, the cooperation between the first drive assembly 50 and the second drive assembly 60 can stably constrain the movement stroke of the moving part 30, which is beneficial to improving the consistency and reliability of the opening and closing action of the door 20.
[0097] The machine body 10 includes an outer shell and an inner liner 11. The outer shell covers the outside of the inner liner 11. The inner liner 11 has a washing chamber 12 inside. The door 20 is hinged to the machine body 10 via a hinge shaft and is used to selectively close the opening of the washing chamber 12 to form an access channel for loading and unloading tableware.
[0098] In one possible implementation, the door 20 and the body 10 form a reliable rotating pair through a hinge, pivot, or hinge, and the width and height of the door 20 match the opening of the body 10 to ensure a good sealing fit when closed and to form a sufficient dehumidification channel when open.
[0099] In one possible implementation, the movable member 30 is moved along a first direction and disposed within the body 10. Under the action of the drive structure, the movable member 30 reciprocates along a straight line and cooperates with the door lock assembly 40. The drive structure is used to transmit the driving force to the door lock assembly 40 through the movable member 30, so that the door lock assembly 40 drives the door 20 to switch between a closed state and an open state.
[0100] In one possible implementation, refer to Figure 6 and Figure 7 As shown, the movable member 30 can be constructed as a strip, a rod, or a sliding member with a locking protrusion. The axial direction of the movable member 30 is along the first direction, and its material can be a metal part, a reinforced plastic part, or a metal-coated plastic part.
[0101] refer to Figure 1 and Figure 2 As shown, the door lock assembly 40 is disposed on the door body 20 and cooperates with the moving part 30. The door lock assembly 40 is a locking mechanism for realizing the hooking, limiting and releasing of the door body 20 and the moving part 30.
[0102] In one possible implementation, the door lock assembly 40 is installed on the side of the door body 20 near the opening of the body 10, and is correspondingly arranged with the end of the moving member 30 facing the door body 20, so that the moving member 30 can push or release the door lock assembly 40 after entering the engagement stroke.
[0103] In one possible implementation, the first drive assembly 50 may employ a thermal expansion drive element, and the first drive assembly 50 is arranged inside the machine body 10 near the heat source so as to receive the temperature rise generated by the heating unit during the drying stage.
[0104] In one possible implementation, refer to Figure 2 and Figure 4 As shown, the second drive assembly 60 and the first drive assembly 50 are arranged inside the body 10 along the same straight line or approximately the same straight line, for example, arranged along the first direction, to form a push-pull balance relationship. The second drive assembly 60 provides a reset action in the opposite direction to the first drive assembly 50, so that the moving part 30 can return to its original position when the action of the first drive assembly 50 weakens, and cooperate to complete the return to its original position when the action of the first drive assembly 50 is restored.
[0105] In this example, the first direction reference Figure 1 and Figure 4 The X-axis indicates the direction, and the first position and the second position are set at intervals along the first direction, respectively corresponding to the stroke boundaries required for the closed state and the open state of the door 20. The displacement of the moving part 30 between the first position and the second position is adapted to the required opening angle of the door 20, so as to ensure that the door 20 can switch from the closed state to the open state for dehumidification, and close again after the conditions are restored.
[0106] The dishwasher provided in this application embodiment, during operation, after completing the washing and entering the drying stage, refers to... Figure 3 As shown, the heating unit 80 inside the body 10 gradually heats up, causing the temperature of the first drive component 50 to rise.
[0107] refer to Figure 4 and Figure 5 As shown, in response to the temperature of the first drive component 50 reaching or exceeding the preset temperature, the action state of the first drive component 50 on the moving part 30 changes, the force balance formed between the first drive component 50 and the second drive component 60 is broken, and the drive structure pushes the moving part 30 from the first position to the second position along the first direction. During the movement, the moving part 30 releases the locked state of the door body 20 through the linkage of the door lock component 40, and drives the door body 20 from the closed state to the open state at the hinge point of the door body 20, thereby forming a channel for venting water vapor between the door body 20 and the machine body 10, so that the moisture generated during the drying stage can be discharged in time, reducing the retention and condensation of moisture inside the washing chamber 12.
[0108] After the drying process is completed, the internal temperature of the machine body 10 gradually decreases. The driving force of the first drive component 50 returns to its initial state or weakens as the temperature changes. With the reverse reset action of the second drive component 60, the drive structure pushes the moving part 30 back from the second position to the first position. When the moving part 30 returns, it re-establishes a locking engagement with the door lock component 40 and drives the door 20 to gradually return to the closed state, thereby restoring the closed environment of the washing chamber 12 inside the machine body 10.
[0109] Example 1
[0110] In one possible implementation, when the driving force of the first drive assembly 50 on the moving member 30 is greater than the force exerted by the second drive assembly 60 on the moving member 30, the first drive assembly 50 drives the moving member 30 to move from the second position to the first position, so that the moving member 30 drives the door 20 to switch from the open state to the closed state.
[0111] When the driving force of the first drive assembly 50 on the moving part 30 is less than the force of the second drive assembly 60 on the moving part 30, the second drive assembly 60 drives the moving part 30 to move from the first position to the second position, so that the moving part 30 drives the door 20 to switch from the closed state to the open state.
[0112] In one possible implementation, the first drive assembly 50 and the second drive assembly 60 are typically arranged at intervals along a first direction, and at least a portion of the moving member 30 is located between the first drive assembly 50 and the second drive assembly 60 and is simultaneously subjected to forces in opposite directions. The first drive assembly 50 and the second drive assembly 60 may act on the moving member 30 by means of direct pushing, pulling, adsorption, or elastic recovery.
[0113] To ensure operational stability, the working stroke of the first drive assembly 50 and the reset stroke of the second drive assembly 60 should both cover the full stroke range of the moving part 30.
[0114] When the dishwasher enters the drying stage, the first drive component 50 gradually changes the driving force on the moving part 30 under the action of temperature change, and forms a continuous mechanical antagonistic relationship with the opposing force applied by the second drive component 60.
[0115] When the driving force of the first drive assembly 50 on the moving part 30 is greater than the force of the second drive assembly 60 on the moving part 30, that is, when the driving force of the first drive assembly 50 on the moving part 30 is dominant, the moving part 30 moves to the first position under the action of the first drive assembly 50 and remains in the first position, so that the moving part 30 drives the door body 20 to switch from the open state to the closed state and remains in the closed state.
[0116] When the driving force of the first driving component 50 on the moving part 30 is less than the force of the second driving component 60 on the moving part 30, that is, when the driving force of the second driving component 60 on the moving part 30 is dominant, the moving part 30 moves to the second position under the action of the second driving component 60 and remains in the second position, so that the moving part 30 drives the door 20 to switch from the closed state to the open state and remains in the open state. Steam is discharged through the gap of the door 20, avoiding secondary moisture caused by steam condensation inside the inner liner 11, which would affect the drying effect of the tableware.
[0117] In this application, since the first drive component 50 changes the magnitude of the driving force on the moving part 30 when the temperature changes, the displacement direction of the moving part 30 can be directly controlled by comparing the force values of the first drive component 50 and the second drive component 60. Without the need for additional complex motor transmission or multi-level control mechanisms, the door 20 can automatically open and automatically reset during temperature changes. Therefore, while ensuring dehumidification efficiency, it can improve the simplification of structure, the reliability of operation, and the safety during use, and help reduce assembly costs and maintenance burden.
[0118] Based on the foregoing embodiments, refer to Figure 2 , Figure 6 and Figure 7As shown, the first drive assembly 50 includes: a first magnetic element 51 and a second magnetic element 52. The first magnetic element 51 is disposed on the body 10; the second magnetic element 52 is connected to the moving part 30. At least one of the first magnetic element 51 and the second magnetic element 52 is a temperature-sensitive magnetic element. The Curie temperature point of the temperature-sensitive magnetic element is higher than the washing water temperature of the dishwasher. The first magnetic element 51 and the second magnetic element 52 are positioned opposite each other to generate a magnetic force between the body 10 and the moving part 30.
[0119] In one possible implementation, the first magnetic element 51 may be disposed on the outer side wall or outer top wall of the inner liner 11, and the second magnetic element 52 is connected to the movable element 30 and moves synchronously with the movable element 30 along the first direction. The first magnetic element 51 and the second magnetic element 52 maintain a preset distance and are spatially opposite each other in a stationary state to ensure that the magnetic force acts on the movable element 30.
[0120] When the first magnetic component 51 and the second magnetic component 52 are positioned opposite each other, a magnetic force is formed between the body and the moving component 30. The magnetic force between the first magnetic component 51 and the second magnetic component 52 is adjusted accordingly as the magnetic properties of the temperature-sensing magnetic component change. If the same poles are opposite each other, a repulsive drive can be formed. If opposite poles are opposite each other, an attractive drive can be formed. The specific arrangement can be set according to the return direction and the opening direction of the moving component 30.
[0121] In one possible implementation, the first magnetic element 51 and the second magnetic element 52 can be in the form of a block magnet, a sheet magnet, a ring magnet, or an arc magnet, respectively. The material can be a temperature-sensitive magnetic alloy, ferrite, neodymium iron boron, samarium cobalt, permanent magnet rubber, or a metal-based magnet, with at least one of them using a temperature-sensitive magnetic material to achieve temperature response. Alternatively, multiple magnets can be arranged in an array to form a more uniform magnetic field distribution and a more stable driving force output. The dimensions of the first magnetic element 51 and the second magnetic element 52 are typically matched according to the required magnetic force and installation space.
[0122] At least one of the first magnetic element 51 and the second magnetic element 52 is a temperature-sensitive magnetic element. The magnetic properties of the temperature-sensitive magnetic element change when the ambient temperature changes. When the ambient temperature rises to near or reaches the preset temperature, the magnetic force weakens or disappears, thereby enabling the drive structure to switch the position of the moving element 30 accordingly during the drying stage.
[0123] The Curie temperature of the temperature-sensing magnetic component is higher than the washing water temperature of the dishwasher, so that the temperature-sensing magnetic component remains stable during the washing stage and is not accidentally triggered by the high temperature washing water, thereby ensuring that the door 20 will not open unexpectedly during the washing process.
[0124] In one possible implementation, the first magnetic element 51 is a temperature-sensitive magnetic element, and the second magnetic element 52 is a permanent magnet.
[0125] In one possible implementation, the first magnetic element 51 is a magnetic component whose magnetic strength can change with ambient temperature. During the dishwasher drying stage, it can change its attractive or repulsive force on the second magnetic element 52 according to the temperature, thereby participating in driving the moving component 30 to generate displacement. The second magnetic element 52 is a permanent magnet that continuously maintains a magnetic field output. The permanent magnet is connected to the moving component 30 and is positioned relative to the first magnetic element 51.
[0126] When the magnetic force between the first magnetic element 51 and the second magnetic element 52 can overcome the reverse force of the second drive assembly 60, the second magnetic element 52 drives the moving element 30 to move along the first direction. To ensure the stability of the magnetic circuit, the temperature-sensing magnetic element and the permanent magnet are usually configured with a small gap fit to generate sufficient driving force when the door 20 needs to be opened, and to return to the closed state after the temperature drops.
[0127] In one possible implementation, the thermosensitive magnetic component can take the form of a block, sheet, strip, or insert structure. The material of the thermosensitive magnetic component can be a ferromagnetic alloy with an adjustable Curie point, a ferrite composite material, a samarium cobalt thermosensitive material, or other materials with thermotropic magnetic properties. The permanent magnet can be made of materials such as neodymium iron boron, ferrite, samarium cobalt, or rubber magnets, and its structural form can be block, strip, arc, ring, or multi-pole array.
[0128] This application sets the first magnetic component 51 as a temperature-sensing magnetic component and the second magnetic component 52 as a permanent magnet, so that temperature changes can be directly converted into changes in magnetic driving force. This enables the automatic opening and closing of the door 20 without the need for additional complex motors and transmission mechanisms. This not only reduces the number of parts, simplifies the structure, and lowers assembly and maintenance costs, but also allows the timing of dehumidification to be matched with the drying temperature, improving dehumidification efficiency while ensuring safety in use.
[0129] In one possible implementation, refer to Figure 5 and Figure 6 As shown, the dishwasher also includes: a guide structure 70 disposed in the body 10, the guide structure 70 having a guide groove 71 extending along a first direction inside the guide structure 70, a first magnetic element 51 disposed in the guide groove 71, and one end of the moving element 30 extending into the guide groove 71. The guide groove 71 is used to guide the movement of the moving element 30. In this application, the guide structure 70 is used to define the movement trajectory of the moving element 30 in the first direction and to provide a relatively stable arrangement space for the first magnetic element 51.
[0130] In one possible implementation, the guide structure 70 is designed to ensure that the moving part 30 moves only along the first direction when it is acted upon by the first drive component 50 and the second drive component 60. Under the guidance of the guide structure 70, the moving part 30 remains in a controllable guiding state within its stroke, thus preventing problems such as swaying, shaking, or jamming of the moving part 30 during the opening and closing linkage of the door 20.
[0131] In one possible implementation, refer to Figure 8 , Figure 9 and Figure 10 As shown, the guide structure 70 is disposed on the body 10. The guide structure 70 may be disposed on the side wall of the inner liner 11 or on the top wall of the inner liner 11.
[0132] In one possible implementation, the guide structure 70 can be installed by fixing it to the inner liner 11 using screws, clips, or welding.
[0133] In one possible implementation, the guide structure 70 can be made of metal profile, engineering plastic, composite material or heat-resistant resin.
[0134] In one exemplary embodiment, reference 5 and Figure 10 As shown, the guide structure 70 includes a first fixing plate 72 and a second fixing plate 73 disposed opposite to each other. A guide groove 71 is formed in the space between the first fixing plate 72 and the second fixing plate 73. The first fixing plate 72 and the second fixing plate 73 can be connected to the top wall of the inner liner 11. The first fixing plate 72 and the second fixing plate 73 play a blocking role in the oblique movement of the moving member 30, ensuring that the moving member 30 moves in the guide groove 71.
[0135] In one possible implementation, the guide groove 71 can be an integral, elongated, through-type structure, and the cross-sectional shape of the guide groove 71 can be U-shaped, rectangular, or V-shaped.
[0136] The guide groove 71 of the guide structure 70 forms positional and attitude constraints on the moving part 30, ensuring that the moving part 30 can only reciprocate within the guide groove 71 along the first direction, and will not deviate from the path due to inertia, external disturbances, or thermal deformation of components during the opening process of the door 20. At the same time, the first magnetic element 51 is fixed within the guide groove 71, maintaining a stable magnetic coupling relationship with the end of the moving part 30 extending into the guide groove 71. When the force between the first drive assembly 50 and the second drive assembly 60 changes, the moving part 30 will move smoothly under the guidance of the guide groove 71, and through the door lock assembly 40, drive the door 20 to switch from the closed state to the open state or from the open state back to the closed state, improving the smoothness of the automatic opening and closing process of the door 20.
[0137] In one possible implementation, refer to Figure 5 , Figure 6 and Figure 10 As shown, the side wall of the moving part 30 has a stop protrusion 31, and the second drive assembly 60 includes a limiting baffle 61 and an elastic sleeve 62. The limiting baffle 61 is disposed on the body 10, and the limiting baffle 61 has an avoidance hole 611 for the moving part 30 to pass through. The elastic sleeve 62 is sleeved on the outer periphery of the moving part 30, and the two ends of the elastic sleeve 62 abut against the stop protrusion 31 and the limiting baffle 61 respectively.
[0138] In one possible implementation, the stop protrusion 31 is an annular step, radial flange, locally thickened shoulder, or pin-shaped shoulder connected to the outer periphery of the moving member 30. The stop protrusion 31 provides a clear axial abutment end point for the elastic sleeve 62. When the moving member 30 is driven to the second position by the first drive assembly 50, the elastic sleeve 62 generates pre-compression and stores elastic potential energy. After the driving force of the first drive assembly 50 weakens, the moving member 30 is pushed back to its original position by the rebound force of the elastic sleeve 62.
[0139] The limiting baffle 61 has an clearance hole 611 inside for the moving member 30 to pass through. The clearance hole 611 provides a passage for the moving member 30, so that when the moving member 30 moves in the first direction, the clearance hole 611 and the moving member 30 form an appropriate fitting clearance, which takes into account both smooth sliding and guiding stability. The limiting baffle 61 also serves as the other end support surface of the elastic sleeve 62, so that the elastic sleeve 62 is compressed when the moving member 30 is displaced, and stably outputs a restoring force when it rebounds.
[0140] In one possible implementation, the limiting baffle 61 can be fixedly connected to the inner liner 11 by screws, clips, or welding. The limiting baffle 61 is located on the movement path of the moving member 30, and the axis of the clearance hole 611 is consistent with the movement direction of the moving member 30 to reduce frictional resistance and prevent swaying and jamming.
[0141] In one possible implementation, the limiting baffle 61 may be L-shaped. For example, the limiting baffle 61 includes a horizontal plate and a vertical plate connected to each other. The clearance hole 611 may be opened in the vertical plate. The vertical plate is approximately parallel to the vertical surface where the stop protrusion 31 is located. The horizontal plate may cover the top of the elastic sleeve 62.
[0142] For example, the elastic sleeve 62 can be in the form of a rubber sleeve, silicone sleeve, foamed elastic sleeve, spring sleeve or corrugated tube elastic element; the material can be heat-resistant rubber, heat-resistant silicone, elastomer composite material, metal spring steel or plastic-coated elastic element; the free length can be set according to the displacement range of the moving member 30 from the first position to the second position.
[0143] In one possible implementation, refer to Figure 9 , Figure 11 and Figure 12 As shown, the door lock assembly 40 includes a linkage 41, which is movably disposed on the door body 20 along a second direction. The moving member 30 has a locking hook 32 at one end facing the door body 20, and the locking hook 32 has a locking groove 321. When the moving member 30 moves along a first direction, the locking hook 32 pushes the linkage 41 along the second direction, so that the linkage 41 and the locking hook 32 switch between a hooked state and a released state. In the hooked state, the linkage 41 is located in the locking groove 321, and the end of the locking hook 32 facing the door body 20 abuts against the door body 20. In the released state, the linkage 41 disengages from the locking groove 321.
[0144] In one possible implementation, the linkage 41 forms a releasable mechanical connection between the door 20 and the movable member 30. Its function is that when the movable member 30 moves in the first direction, it responds to the pushing of the locking hook 32 and displaces in the second direction, thereby locking or unlocking the door 20. In this example, the second direction refers to... Figure 1 The direction indicated by the Y-axis.
[0145] In one possible implementation, the linkage 41 can be arranged on the side of the door 20 facing the machine body 10. The locking hook 32 functionally undertakes both the pushing action on the linkage 41 and the locking and retaining action. The linkage 41 is located in the locking groove 321, which can form a limiting support, thereby preventing the door 20 from being accidentally opened under the action of external force. The locking hook 32 can be injection molded or integrally stamped.
[0146] refer to Figure 9 , Figure 10 and Figure 12 As shown, the movable member 30 is displaced along the first direction, and the locking hook 32 at one end of the movable member 30 toward the door body 20 applies a force to the linkage member 41. The linkage member 41 overcomes the local elastic resistance on the door body 20 and generates a displacement along the second direction.
[0147] refer to Figure 13 , Figure 14 and Figure 15 As shown, the linkage 41 has a first guide surface 411 and a second guide surface 412 on opposite sides; Reference Figure 16 and Figure 17 As shown, when the moving member 30 moves closer to the door body 20 along the first direction, the outer wall of the locking hook 32 abuts against the first guide surface 411 to guide the linkage member 41 to move away from the locking hook 32 along the second direction; Reference Figure 18 and Figure 19 As shown, when the moving member 30 moves away from the door body 20 in the first direction, the inner wall of the locking hook 32 abuts against the second guide surface 412 to guide the linkage member 41 to move away from the locking hook 32 in the second direction.
[0148] In one possible implementation, the linkage 41 adapts to the contact direction of the lock hook 32 through the first guide surface 411 and the second guide surface 412 formed on opposite sides. This allows the moving member 30 to move towards or away from the door body 20, and the linear motion of the moving member 30 is converted into the displacement of the linkage 41 along the second direction through the contact transition between the lock hook 32 and the linkage 41. This enables the linkage 41 to stably enter or exit the locking groove 321 and allows the door body 20 to smoothly switch between the hooked state and the released state.
[0149] In one possible implementation, the first guide surface 411 is the contact side of the moving member 30 when it approaches the door body 20 in the first direction, and the second guide surface 412 is the contact side of the moving member 30 when it moves away from the door body 20 in the first direction.
[0150] In one possible implementation, refer to Figure 15 As shown, the bottom end of the first guide surface 411 is flush with the bottom end of the second guide surface 412; relative to the first direction, the tilt angle of the first guide surface 411 is greater than the tilt angle of the second guide surface 412.
[0151] In one possible embodiment of this application, the first guide surface 411 and the second guide surface 412 can be understood as two differentiated guide ramps on the linkage 41 for engaging with the locking hook 32.
[0152] In one possible implementation, the top of the first guide surface 411 is higher than the top of the second guide surface 412.
[0153] In one exemplary implementation, the linkage 41 may be made of wear-resistant plastic, metal, or metal-coated plastic.
[0154] Considering that dishwashers operate in high temperature and high humidity environments for extended periods, the first guide surface 411 and the second guide surface 412 may also be locally provided with a wear-resistant layer, a low-friction coating, or reinforced glass fiber material to improve durability during repeated contact.
[0155] refer to Figure 20 , Figure 21 and Figure 22 As shown, the first guide surface 411 and the second guide surface 412 are asymmetrical. This is because the door 20 makes a circular motion around the hinge axis during the opening process. As the opening angle of the door 20 gradually increases, the position of the linkage 41 in the height direction gradually decreases. Conversely, during the closing process of the door 20, the position of the linkage 41 in the height direction gradually increases. The height of the linkage 41 remains constant and will not change due to the opening or closing of the door 20.
[0156] refer to Figure 16 , Figure 21 and Figure 22 As shown, when the moving part 30 is displaced along the first direction under the action of the first drive assembly 50 and the second drive assembly 60, during the process of moving from the first position to the second position, when the moving part 30 moves towards the door body 20, the locking hook 32 first contacts the first guide surface 411 on one side of the linkage part 41. Since the top of the first guide surface 411 is higher and the inclination angle is larger, refer to Figure 17 , Figure 23 and Figure 24 As shown, the locking hook 32 can quickly push the linkage 41 to shift along the second direction within a small forward displacement, so that the linkage 41 can enter the locking groove 321 of the locking hook 32 as soon as possible, completing the switch from the release state to the hook-pull state. Then, the moving member 30 continues to move closer to the door body 20 along the first direction until it moves to the first position.
[0157] refer to Figure 18 , Figure 25 and Figure 26 As shown, when the moving part 30 moves along the first direction from the second position to the first position, as the moving part 30 moves away from the door body 20, the locking hook 32 and the linkage part 41 first maintain a hooked state for a certain period of time, causing the door body 20 to gradually close, so that the opening angle of the door body 20 gradually decreases. (Refer to...) Figure 19 , Figure 27 and Figure 28 As shown, until the locking hook 32 begins to contact the top of the second guide surface 412 of the linkage member 41, under the guidance of the second guide surface 412, the linkage member 41 gradually leaves the locking groove 321, realizing the switch from the hook-pull state to the release state, preventing the linkage member 41 from disengaging from the locking groove 321 before the locking hook 32 has driven the door 20 to close, thus ensuring that the door 20 can be closed stably.
[0158] Because the first guide surface 411 and the second guide surface 412 are set differently in height and tilt angle, the contact process of the locking hook 32 in the two directions is respectively characterized by rapid entry into the hooking state and gradual entry into the release state, which improves the stability and consistency of the automatic opening and closing action of the whole machine.
[0159] In one possible implementation, refer to Figure 12 As shown, the door body 20 has a limiting step 21, the linkage member 41 and the limiting step 21 are arranged at intervals along the second direction, and the door lock assembly 40 also includes an elastic member 42, which is located between the linkage member 41 and the limiting step 21. The two ends of the elastic member 42 are respectively connected to the linkage member 41 and the limiting step 21. Along the second direction, the direction of the force exerted by the elastic member 42 on the linkage member 41 is opposite to the direction of movement of the linkage member 41 driven by the moving member 30.
[0160] In one possible implementation, the limiting step 21 is arranged inside the door body 20. The limiting step 21 and the linkage 41 are spaced apart in the second direction. The limiting step 21 provides a fixed support end for the elastic member 42. The elastic member 42 can be directly mounted between the linkage 41 and the limiting step 21, or the end can be connected through a hook hole, a slot or a spring seat.
[0161] When the linkage 41 is pushed by the moving member 30, it moves along the second direction. The elastic member 42 is compressed or stretched accordingly. After the external force is released, it relies on its own elastic restoring force to exert an action in the opposite direction, so that the linkage 41 returns to the initial position.
[0162] The limiting step 21 can be a stepped boss integrally injection molded with the door body 20, or an independently assembled metal block, etc. The elastic element 42 can be a compression spring, a tension spring, or other moisture- and temperature-resistant elastic element.
[0163] In one possible implementation, to adapt to the humid and high-temperature working environment inside the dishwasher, the elastic element 42 can be made of stainless steel spring with anti-corrosion treatment or heat-resistant silicone to improve long-term stability.
[0164] The distance between the linkage 41 and the limiting step 21 should be greater than the free state size of the elastic element 42 but less than the maximum allowable compression or tension stroke of the elastic element 42, so that the elastic element 42 can generate sufficient restoring force when compressed without permanent deformation, and the linkage 41 can reliably displace during the engagement of the locking hook 32.
[0165] refer to Figure 12 , Figure 23 and Figure 24 As shown, the moving part 30 reciprocates along the first direction under the coordinated action of the first drive assembly 50 and the second drive assembly 60, and realizes the locking and releasing conversion of the door 20 through the cooperation between the locking hook 32 and the linkage 41; during the process of the door 20 being opened or about to be opened, the locking hook 32 exerts a pushing force on the linkage 41 along the second direction, causing the linkage 41 to be displaced relative to the door 20 and enter the corresponding hooking or releasing position, while the elastic part 42 located between the linkage 41 and the limiting step 21 undergoes compression, stretching or torsional deformation in the process to store elastic potential energy and form a restoring force on the linkage 41 opposite to its direction of movement.
[0166] When the pushing force of the moving part 30 weakens or is released, the elastic part 42 drives the linkage part 41 to return to its original position in the second direction by relying on its own restoring force, so that the linkage part 41 is close to the initial installation position again and maintains a reasonable distance from the limit step 21, so that the door lock assembly 40 can accurately respond to the push of the lock hook 32 again in the next action.
[0167] Since the direction of the force exerted by the elastic element 42 on the linkage element 41 is opposite to the direction of movement of the linkage element 41 driven by the moving element 30, this structure can provide a timely reset force after the linkage element 41 completes the force displacement, thus preventing the linkage element 41 from being stuck in the middle position due to friction, inertia or slight off-center load, thereby improving the repeatability and return reliability of the door lock assembly 40, and helping to ensure the stability and safety of the door body 20 during the drying and dehumidification stage of opening and closing.
[0168] In one possible implementation, refer to Figure 12 and Figure 13 As shown, the elastic member 42 has a first anti-detachment part 421 and a second anti-detachment part 422 connected to its two ends respectively. The linkage member 41 is connected to a fixing block 413. The fixing block 413 has an installation groove 4131. The limiting step 21 has a channel for the elastic member 42 to pass through. The first anti-detachment part 421 cannot pass through this channel and is embedded in the installation groove 4131. The second anti-detachment part 422 is located on the side of the limiting step 21 facing away from the linkage member 41. Under the action of the first and second anti-detachment parts 422, the elastic element 42 can be prevented from disengaging from the linkage element 41 and the limiting step 21, so that the elastic element 42 continuously provides a constant elastic tension between the linkage element 41 and the limiting step 21, pulling the linkage element 41 toward the limiting step 21, which can limit the movement distance of the linkage element 41. After the locking hook 32 of the moving part 30 drives the linkage element 41 to move along the second direction, the linkage element 41 is reset under the action of the elastic tension of the elastic element 42.
[0169] In one possible implementation, refer to Figure 29 As shown, the door 20 includes a door shell 23 and a door liner 24. The door liner 24 is disposed on the side of the door shell 23 facing the machine body 10, and the side of the door shell 23 facing away from the machine body 10 is covered with a glass plate as an exterior panel. When the door 20 is closed, the door liner 24 faces the washing chamber 12 inside the machine body 10, and the door lock assembly 40 is disposed on the door liner 24.
[0170] In one possible implementation, the door body 20 also includes a display panel box 25, which is installed on the top of the door shell 23. The display panel box 25 contains a support plate 27 and a display panel 26. The support plate 27 supports and fixes the display panel 26. The display glass 28 covers the surface of the display panel box 25, which not only protects the display panel 26 from dust and moisture, but also clearly displays the operation information on the display panel 26, making it convenient for users to view and operate.
[0171] When the door 20 is closed, the position of the display panel box 25 corresponds to the moving part 30, so that the locking hook 32 of the moving part 30 can push the display panel box 25 to open the door 20.
[0172] In one possible implementation, the limiting step 21 is located on the display panel 26. When the linkage 41 is subjected to the force of the moving member 30 along the second direction, the linkage 41 moves along the second direction against the force of the elastic member 42. When there is no external force, the linkage 41 moves closer to the display panel 26 under the action of the elastic member 42.
[0173] In one possible implementation, a guide groove 22 is formed inside the display panel box 25, and the guide groove 22 guides the linkage 41 to move stably in the second direction.
[0174] In one possible implementation, refer to Figure 3 As shown, the dishwasher also includes a heating unit 80 and a control unit 90. The heating unit 80 is located at the top of the body 10 and corresponds to the position of the temperature-sensing magnetic component. The heating unit 80 is used for drying heating and heating the temperature-sensing magnetic component. The control unit 90 is electrically connected to the heating unit 80. When the door 20 switches from the closed state to the open state, the control unit 90 controls the heating unit 80 to stop heating.
[0175] In this application, the heating unit 80 is arranged on the top of the body 10, and the heating area of the heating unit 80 corresponds to the position of the temperature-sensing magnetic element, so that heat can be transferred to the temperature-sensing magnetic element along a shorter path, thereby improving the thermal response efficiency. The heating unit 80 not only performs the function of heating the tableware and moisture in the washing chamber 12 during the drying stage, but also performs the function of thermally stimulating the temperature-sensing magnetic element, so that the temperature-sensing magnetic element changes its magnetic state after reaching the preset temperature and drives the first drive component 50 to operate.
[0176] In one possible implementation, the control unit 90 controls the on / off state of the heating unit 80 according to the dishwasher's operating status, thereby achieving drying heating, temperature triggering, and shutdown linkage after the door is opened. In one possible embodiment, the control unit 90 can be a microcontroller control board, a relay control board, a power control module, or an integrated main control board. Its installation position can be integrated with the main control circuit board of the whole machine, or it can be set independently in the electrical control box and electrically connected to the heating unit 80 through wires.
[0177] In one possible implementation, the heating unit 80 may be an electric heating tube, a positive temperature coefficient (PTC) heater, a hot air heating module, an infrared heating element, or a composite drying module, and its heating element may be composed of a resistance heating wire, a ceramic substrate, a metal sheath, or a composite heat sink.
[0178] In another possible embodiment, the heating unit 80 can also employ a top hot air outlet combined with an air duct structure to form a directional heat delivery method, so that the heat is more concentrated on the area where the temperature-sensitive magnetic component is located. The heating area of the heating unit 80 should generally cover the area where the temperature-sensitive magnetic component is located, and the distance between it and the temperature-sensitive magnetic component can be set to a range that can form a stable thermal coupling within a preset time, so as to ensure timely heating and triggering of the door 20 during the drying stage.
[0179] During operation, the control unit 90 first puts the heating unit 80 into the drying state. The heating unit 80 outputs heat into the machine body 10, which on the one hand increases the air temperature inside the cavity to promote the evaporation of moisture on the surface of the tableware, and on the other hand transfers the heat to the temperature-sensing magnetic component corresponding to its position, so that the temperature of the temperature-sensing magnetic component gradually rises and reaches the preset temperature. This, in conjunction with the first drive component, changes the magnitude of the driving force on the moving component 30, driving the moving component 30 and the door lock component 40 to work together, ultimately switching the door 20 from the closed state to the open state to release moisture.
[0180] When the door 20 is opened, the control unit 90 immediately outputs a stop command, causing the heating unit 80 to shut off power or operate at reduced power. This prevents energy waste, localized overheating, or unnecessary heat loss caused by continued heat output while the door is open. It also helps reduce the temperature rise near the door, improving user safety. Through the cooperation of the heating unit 80 and the control unit 90, the dishwasher can achieve targeted temperature utilization during the drying stage and stop heating promptly after the door 20 is opened. This ensures efficient dehumidification while reducing energy consumption and enhancing the safety and stability of the entire machine.
[0181] In one possible implementation, refer to Figure 3 As shown, the body 10 also includes a fan assembly 13 and a cover plate 14. The fan assembly 13 is located on the outer wall of the inner tank 11 and corresponds to the position of the heating unit 80. The fan assembly 13 drives the airflow to send the heat generated by the heating unit 80 into the washing chamber 12 inside the inner tank 11 along with the airflow. The high-temperature hot air accelerates the vaporization of water vapor, realizing the rapid drying of the inner wall of the washing chamber 12 and the tableware, preventing water accumulation and mold. In addition, the hot air can continuously increase the ambient temperature of the washing chamber. The high temperature destroys the living environment of bacteria and microorganisms, sterilizes the tableware and the inner wall of the chamber with moist heat, and improves the hygiene level.
[0182] In one possible implementation, the cover plate 14 can be connected to the inner liner 11 by screws, bolts, or clips. The cover plate 14 covers the side of the fan assembly 13 facing away from the inner liner 11 and is used to protect the fan assembly 13.
[0183] This invention utilizes the effect of temperature changes on the driving force and combines the synergistic effect of dual driving components in opposite directions to achieve automatic switching of the door's opening and closing state according to temperature during the drying process, thereby reducing structural complexity and improving the overall effect of dehumidification and safety of use.
[0184] In the first embodiment of this application, refer to Figure 2 and Figure 5 As shown, the first magnetic component 51 is a temperature-sensitive magnetic component, and the second magnetic component 52 is a permanent magnet. The temperature-sensitive magnetic component uses a temperature-sensitive magnetic material, which can be a Curie material, such as ferrite magnets, neodymium iron boron magnets, or conventional iron-nickel alloys.
[0185] This application utilizes the temperature-magnetic properties of a temperature-sensitive magnetic material in a temperature-sensitive magnetic component. During the drying stage of the dishwasher, the heating unit 80 triggers the magnetic material to lose its magnetism, releasing the elastic force of the elastic sleeve 62 to push open the door 20. During the cooling stage, the magnetic material regains its magnetism, driving the door 20 to close via magnetic attraction. This solution eliminates the need for a motor and electronic control module, achieving automatic control through the linkage of material properties and mechanical energy storage. It realizes a cycle of automatic door opening during the drying stage and automatic door closing during the cooling stage, significantly simplifying the structure and reducing costs.
[0186] Along the first direction, the first drive assembly 50 is further away from the door body 20 relative to the second drive assembly 60. The first drive assembly 50 is located at the end of the moving member 30 that is further away from the door body 20. The second magnetic member 52 is connected to the moving member 30. The first magnetic member 51 is disposed on the body 10. Along the first direction, the second magnetic member 52 is further away from the door body 20 relative to the first magnetic member 51. The opposite magnetic poles of the first magnetic member 51 and the second magnetic member 52 are opposite to each other to form a magnetic attraction. Furthermore, the stop protrusion 31 is further away from the first drive assembly 50 relative to the limiting baffle 61. The two ends of the elastic sleeve 62 abut against the stop protrusion 31 and the limiting baffle 61, respectively.
[0187] In one possible implementation, the movable element 30 is rod-shaped.
[0188] In one possible implementation, the stop protrusion 31 is an annular step, radial flange, locally thickened shoulder, or pin-shaped shoulder connected to the outer periphery of the moving member 30. The stop protrusion 31 provides a clear axial abutment end point for the elastic sleeve 62. When the moving member 30 is pushed to the second position by the first drive assembly 50, the elastic sleeve 62 generates pre-compression and stores elastic potential energy. After the driving force of the first drive assembly 50 weakens, the moving member 30 is pushed back to its original position by the rebound force of the elastic sleeve 62.
[0189] The limiting baffle 61 has an clearance hole 611 inside for the moving member 30 to pass through. The clearance hole 611 provides a passage for the moving member 30, so that when the moving member 30 moves in the first direction, the clearance hole 611 and the moving member 30 form an appropriate fitting clearance, which takes into account both smooth sliding and guiding stability. The limiting baffle 61 also serves as the other end support surface of the elastic sleeve 62, so that the elastic sleeve 62 is compressed when the moving member 30 is displaced, and stably outputs a restoring force when it rebounds.
[0190] In one possible implementation, the limiting baffle 61 can be fixedly connected to the inner liner 11 by screws, clips, or welding. The limiting baffle 61 is located on the movement path of the moving member 30, and the axis of the clearance hole 611 is consistent with the movement direction of the moving member 30 to reduce frictional resistance and prevent swaying and jamming.
[0191] For example, the elastic sleeve 62 can be in the form of a rubber sleeve, silicone sleeve, foamed elastic sleeve, spring sleeve or corrugated tube elastic element; the material can be heat-resistant rubber, heat-resistant silicone, elastomer composite material, metal spring steel or plastic-coated elastic element; the free length can be set according to the displacement range of the moving member 30 from the first position to the second position.
[0192] When the dishwasher enters the drying stage, the temperature inside the machine body 10 gradually increases. When the first magnetic component 51 is at a higher temperature, its magnetism weakens or even disappears. Correspondingly, the magnetic attraction between the first magnetic component 51 and the second magnetic component 52 decreases or even disappears. The elastic sleeve 62 gradually returns to its original elastic compression state, pushing the stop protrusion 31, causing the moving component 30 to move as a whole. That is, the moving component 30 moves from the first position to the second position under the driving action of the second drive assembly 60. Through the cooperation of the moving component 30 and the door lock assembly 40, the door 20 is switched from the closed state to the open state. This allows the door 20 to automatically open and dehumidify according to the temperature during the drying stage, which helps to reduce the problem of moisture retention and dishwashing re-soaking in the washing chamber 12, thereby improving the drying effect.
[0193] As the drive structure drives the moving part 30 to move from the first position to the second position, the moving part 30 pushes the door body 20, and the door body 20 makes a circular motion around the hinge axis. The linkage part 41 gradually enters the locking groove 321 and forms a hook-pull state. At this time, a mechanical locking relationship is gradually established between the door body 20 and the moving part 30. The moving part 30 pushes the door body 20 to switch from the closed state to the open state to release water vapor.
[0194] After the drying stage ends, the temperature inside the machine body 10 begins to decrease, and the magnetism of the first magnetic component 51 begins to recover. A magnetic attraction force is formed between the first magnetic component 51 and the second magnetic component 52. When the magnetic attraction force is greater than the force exerted by the second drive assembly 60 on the moving component 30, that is, the driving force of the first drive assembly 50 on the moving component 30 is greater than the force exerted by the second drive assembly 60 on the moving component 30, the second magnetic component 52 drives the moving component 30 to move from the second position to the first position. The distance between the stop protrusion 31 and the limiting baffle 61 decreases, and the elastic sleeve 62 is elastically compressed by the pressure of the stop protrusion 31. The moving component 30 drives the door 20 to switch from the open state to the closed state, and under the action of the magnetic attraction force formed between the first magnetic component 51 and the second magnetic component 52, the door 20 remains in the closed state.
[0195] After the drying stage is completed, as the drive structure moves the moving part 30 from the second position to the first position, the pushing relationship between the locking hook 32 and the linkage part 41 is released. The linkage part 41 disengages from the locking groove 321 under the action of its own guide structure or reset force, and the door lock assembly 40 then switches to the released state, and the door body 20 switches from the open state to the closed state.
[0196] Through the above-mentioned linkage method, the linear motion of the moving part 30 can be converted into the locking and unlocking action of the door lock assembly 40, without the need for additional complex independent drive configuration, thus realizing the coordination between the opening and closing of the door 20 and the drying cycle.
[0197] The hooking state of the linkage 41 and the locking hook 32 can improve the positioning accuracy and closing state retention of the door 20 when it is closed, reduce the accidental opening of the door 20 due to vibration or pressure changes, and thus improve the safety of use while ensuring dehumidification efficiency.
[0198] In one possible implementation, a dish rack assembly is also provided inside the washing chamber 12 for carrying tableware.
[0199] In one possible implementation, a water cup is provided on the bottom wall of the inner tank 11. The water cup has a water passage cavity inside. The independently closed water passage cavity can stably accommodate washing water and regulate the water flow direction, ensuring the continuous and stable operation of the dishwasher.
[0200] The washing chamber 12 is equipped with a rotating spray arm with spray holes on its surface. As the spray arm rotates, water is sprayed out from the spray holes to rinse the tableware. Food residue and oil stains on the tableware are washed away by the water flow, thus achieving the cleaning effect of the tableware.
[0201] The bottom of the water cup is connected to a washing pump, an inlet pipe, a drain pipe, a drain pump, and a delivery pipe to form a closed-loop water circuit, ensuring smooth water circulation, inlet, and outlet.
[0202] The washing pump can be connected to the water outlet of the water passage chamber. When the dishwasher is working, the washing pump starts to operate, draws the stored water in the water passage chamber and pressurizes and delivers it. The high-pressure water flow is delivered to the spray arm through the delivery pipe and then sprayed out from the spray holes on the surface of the spray arm. The high-pressure water flow washes away the dirt on the inner tank and the surface of the appliance, completing the washing operation.
[0203] The water inlet pipe is installed at the water inlet interface at the bottom of the water cup, connecting to an external water source. The water inlet pipe is responsible for automatically filling the water chamber. When the dishwasher needs to replenish water, the external water source is smoothly introduced into the water chamber through the water inlet pipe to complete the water storage and replenishment operation, providing sufficient water for subsequent washing water circulation.
[0204] The drain pipe is located at the bottom of the cup, at a low drain port, serving as a dedicated channel for wastewater discharge. One end of the drain pipe connects to the lowest point of the water passage chamber, while the other end extends to the sewer. After washing, wastewater containing stains and oil collects at the bottom of the water passage chamber and is quickly and thoroughly discharged through the drain pipe, preventing wastewater residue from breeding bacteria and producing odors.
[0205] The water cup is also equipped with a filter to intercept food residue in the water flow, prevent blockage of the delivery pipe, spray arm and washing pump, ensure smooth water circulation, reduce the power loss of the washing pump, make the washing operation efficient and energy-saving, and at the same time ensure the cleanliness of the washing water.
[0206] Example 2
[0207] In this second embodiment, reference Figure 2 and Figure 30 As shown, the temperature-sensitive magnetic component uses Curie materials, such as ferrite magnets, neodymium iron boron, and conventional iron-nickel alloys.
[0208] Along the first direction, the first drive assembly 50 is closer to the door body 20 than the second drive assembly 60. The first drive assembly 50 is located at the end of the moving member 30 that is closer to the door body 20. The second magnetic member 52 is connected to the moving member 30. The first magnetic member 51 is disposed on the body 10. Along the first direction, the second magnetic member 52 is farther away from the door body 20 than the first magnetic member 51. The same magnetic poles of the first magnetic member 51 and the second magnetic member 52 are opposite each other, forming a magnetic repulsion force. Furthermore, the stop protrusion 31 is closer to the first drive assembly 50 than the limiting baffle 61. The two ends of the elastic sleeve 62 abut against the stop protrusion 31 and the limiting baffle 61, respectively.
[0209] In one possible implementation, the movable element 30 is rod-shaped.
[0210] In one possible implementation, the stop protrusion 31 is an annular step, radial flange, locally thickened shoulder, or pin-shaped shoulder connected to the outer periphery of the moving member 30. The stop protrusion 31 provides a clear axial abutment end point for the elastic sleeve 62. When the moving member 30 is pushed to the first position by the first drive assembly 50, the elastic sleeve 62 generates pre-compression and stores elastic potential energy. After the driving force of the first drive assembly 50 weakens, the moving member 30 is pushed back to its original position by the rebound force of the elastic sleeve 62.
[0211] The limiting baffle 61 has an clearance hole 611 inside for the moving member 30 to pass through. The clearance hole 611 provides a passage for the moving member 30, so that when the moving member 30 moves in the first direction, the clearance hole 611 and the moving member 30 form an appropriate fitting clearance, which takes into account both smooth sliding and guiding stability. The limiting baffle 61 also serves as the other end support surface of the elastic sleeve 62, so that the elastic sleeve 62 is compressed when the moving member 30 is displaced, and stably outputs a restoring force when it rebounds.
[0212] In one possible implementation, the limiting baffle 61 can be fixedly connected to the inner liner 11 by screws, clips, or welding. The limiting baffle 61 is located on the movement path of the moving member 30. The axis of the clearance hole 611 is consistent with the movement direction of the moving member 30 to reduce frictional resistance and prevent swaying and jamming. The clearance hole 611 can be a U-shaped hole.
[0213] For example, the elastic sleeve 62 can be in the form of a rubber sleeve, silicone sleeve, foamed elastic sleeve, spring sleeve or corrugated tube elastic element; the material can be heat-resistant rubber, heat-resistant silicone, elastomer composite material, metal spring steel or plastic-coated elastic element; the free length can be set according to the displacement range of the moving member 30 from the first position to the second position.
[0214] When the dishwasher enters the drying stage, the temperature inside the machine body 10 gradually rises. When the first magnetic component 51 is at a higher temperature, its magnetism weakens or even disappears. Correspondingly, the magnetic repulsion between the first magnetic component 51 and the second magnetic component 52 decreases or even disappears. The elastic sleeve 62 gradually returns to its original position from its elastically compressed state. The elastic sleeve 62 pushes the stop protrusion 31, causing the moving component 30 to move from the first position to the second position. This, in conjunction with the door lock assembly 40, drives the door 20 to switch from the closed state to the open state. This allows the door 20 to automatically open and dehumidify based on the temperature during the drying stage, helping to reduce moisture retention in the washing chamber 12 and prevent the dishes from becoming damp again, thereby improving the drying effect.
[0215] After the drying stage ends, the temperature inside the machine body 10 begins to decrease, the magnetism of the first magnetic component 51 begins to recover, and a magnetic repulsion force is formed between the first magnetic component 51 and the second magnetic component 52. This magnetic repulsion force is greater than the force exerted by the second drive assembly 60 on the moving component 30. That is, the driving force of the first drive assembly 50 on the moving component 30 is greater than the force exerted by the second drive assembly 60 on the moving component 30. The second magnetic component 52 drives the moving component 30 to move from the second position to the first position. The elastic sleeve 62 undergoes elastic compression, and the door 20 switches from the open state to the closed state. Under the action of the magnetic repulsion force between the first magnetic component 51 and the second magnetic component 52, the door 20 remains in the closed state.
[0216] The remaining structure of this second embodiment is the same as that of the first embodiment, and will not be described again here.
[0217] Example 3
[0218] In this third embodiment, reference Figure 2 and Figure 31 As shown, the temperature-sensing magnetic component uses inverse Curie material. When the temperature is below the material's phase transition temperature, the magnetic force of the inverse Curie material is weak. When the temperature rises above the phase transition temperature, the inverse Curie material undergoes a magnetic structural phase transition, and its magnetism strengthens. The critical phase transition temperature of the inverse Curie material can be precisely controlled, ensuring that the door 20 is only triggered to open and close during the drying stage, avoiding accidental opening during the washing stage.
[0219] Along the first direction, the first drive assembly 50 is closer to the door body 20 than the second drive assembly 60. The first drive assembly 50 is located at the end of the moving member 30 that is closer to the door body 20. The second magnetic member 52 is connected to the moving member 30. The first magnetic member 51 is disposed on the body 10. Along the first direction, the second magnetic member 52 is farther away from the door body 20 than the first magnetic member 51. The opposite magnetic poles of the first magnetic member 51 and the second magnetic member 52 are opposite to each other to form a magnetic attraction. Furthermore, the stop protrusion 31 is farther away from the door body 20 than the limiting baffle 61. The two ends of the elastic sleeve 62 abut against the stop protrusion 31 and the limiting baffle 61, respectively.
[0220] In one possible implementation, the movable element 30 is rod-shaped.
[0221] In one possible implementation, the stop protrusion 31 is an annular step, radial flange, locally thickened shoulder, or pin-shaped shoulder connected to the outer periphery of the moving member 30. The stop protrusion 31 provides a clear axial abutment end point for the elastic sleeve 62. When the moving member 30 is pushed to the second position by the first drive assembly 50, the elastic sleeve 62 generates pre-compression and stores elastic potential energy. After the driving force of the first drive assembly 50 weakens, the moving member 30 is pushed back to its original position by the rebound force of the elastic sleeve 62.
[0222] The limiting baffle 61 has an clearance hole 611 inside for the moving member 30 to pass through. The clearance hole 611 provides a passage for the moving member 30, so that when the moving member 30 moves in the first direction, the clearance hole 611 and the moving member 30 form an appropriate fitting clearance, which takes into account both smooth sliding and guiding stability. The limiting baffle 61 also serves as the other end support surface of the elastic sleeve 62, so that the elastic sleeve 62 is compressed when the moving member 30 is displaced, and stably outputs a restoring force when it rebounds.
[0223] In one possible implementation, the limiting baffle 61 can be fixedly connected to the inner liner 11 by screws, clips, or welding. The limiting baffle 61 is located on the movement path of the moving member 30, and the axis of the clearance hole 611 is consistent with the movement direction of the moving member 30 to reduce frictional resistance and prevent swaying and jamming.
[0224] For example, the elastic sleeve 62 can be in the form of a rubber sleeve, silicone sleeve, foamed elastic sleeve, spring sleeve or corrugated tube elastic element; the material can be heat-resistant rubber, heat-resistant silicone, elastomer composite material, metal spring steel or plastic-coated elastic element; the free length can be set according to the displacement range of the moving member 30 from the first position to the second position.
[0225] As the dishwasher enters the drying stage, the temperature inside the machine body 10 gradually changes. When the first magnetic component 51 is at a higher temperature, its magnetism strengthens. Correspondingly, the magnetic attraction between the first magnetic component 51 and the second magnetic component 52 increases. When the magnetic attraction between the first magnetic component 51 and the second magnetic component 52 is greater than the force exerted by the second drive assembly 60 on the moving component 30, the second magnetic component 52 drives the moving component 30 to move closer to the first magnetic component 51. The elastic sleeve 62 is elastically compressed by the pressure of the stop protrusion 31. That is, the moving component 30 moves from the first position to the second position under the drive of the first drive assembly 50. Through the cooperation of the moving component 30 and the door lock assembly 40, the door 20 is switched from the closed state to the open state. Steam is discharged through the gap in the door 20, avoiding secondary dampness caused by steam condensation inside the inner tank 11. The door 20 automatically opens to release moisture according to the temperature during the drying stage, which helps to reduce the problem of moisture retention in the washing chamber 12 and the re-dampening of tableware, thereby improving the drying effect.
[0226] When the drying stage ends, the temperature inside the machine body 10 decreases, the magnetism of the first magnetic component 51 becomes weak or even non-magnetic, and the magnetic attraction between the first magnetic component 51 and the second magnetic component 52 decreases or even becomes zero. This magnetic attraction is less than the force exerted by the second drive assembly 60 on the moving component 30, that is, the driving force of the first drive assembly 50 on the moving component 30 is less than the force exerted by the second drive assembly 60 on the moving component 30. The elastic sleeve 62 returns to its original state from the elastic compression state. Under the action of its own elastic force, the elastic sleeve 62 pushes the stop protrusion 31, causing the moving component 30 to move from the second position to the first position. The door 20 switches from the open state to the closed state, and under the action of its own elastic force, the door 20 remains in the closed state.
[0227] The remaining structure of this embodiment three is the same as that of embodiment one.
[0228] Example 4
[0229] In this fourth embodiment, reference Figure 2 and Figure 32 As shown, the temperature-sensing magnetic component uses inverse Curie material. When the temperature is below the material's phase transition temperature, the magnetic force of the inverse Curie material is weak. When the temperature rises above the phase transition temperature, the inverse Curie material undergoes a magnetic structure phase transition, and its magnetism strengthens.
[0230] Along the first direction, the first drive assembly 50 is further away from the door body 20 relative to the second drive assembly 60. The first drive assembly 50 is located at the end of the moving member 30 that is further away from the door body 20. The second magnetic member 52 is connected to the moving member 30. The first magnetic member 51 is disposed on the body 10. Along the first direction, the second magnetic member 52 is further away from the door body 20 relative to the first magnetic member 51. The like magnetic poles of the first magnetic member 51 and the second magnetic member 52 are opposite to each other, forming a magnetic repulsion force. Furthermore, the stop protrusion 31 is further away from the door body 20 relative to the limiting baffle 61. The two ends of the elastic sleeve 62 abut against the stop protrusion 31 and the limiting baffle 61, respectively.
[0231] In one possible implementation, the movable element 30 is rod-shaped.
[0232] In one possible implementation, the stop protrusion 31 is an annular step, radial flange, locally thickened shoulder, or pin-shaped shoulder connected to the outer periphery of the moving member 30. The stop protrusion 31 provides a clear axial abutment end point for the elastic sleeve 62. When the moving member 30 is pushed to the second position by the first drive assembly 50, the elastic sleeve 62 generates pre-compression and stores elastic potential energy. After the driving force of the first drive assembly 50 weakens, the moving member 30 is pushed back to its original position by the rebound force of the elastic sleeve 62.
[0233] The limiting baffle 61 has an clearance hole 611 inside for the moving member 30 to pass through. The clearance hole 611 provides a passage for the moving member 30, so that when the moving member 30 moves in the first direction, the clearance hole 611 and the moving member 30 form an appropriate fitting clearance, which takes into account both smooth sliding and guiding stability. The limiting baffle 61 also serves as the other end support surface of the elastic sleeve 62, so that the elastic sleeve 62 is compressed when the moving member 30 is displaced, and stably outputs a restoring force when it rebounds.

The limiting baffle 61 is located on the movement path of the moving member 30, and the axis of the clearance hole 611 is consistent with the movement direction of the moving member 30 to reduce frictional resistance and prevent swaying and jamming.

[0236] As the dishwasher enters the drying stage, the temperature inside the machine body 10 gradually changes. When the first magnetic component 51 is at a higher temperature, its magnetism strengthens. Correspondingly, the magnetic repulsion between the first magnetic component 51 and the second magnetic component 52 increases. When the magnetic repulsion between the first magnetic component 51 and the second magnetic component 52 is greater than the force exerted by the second drive assembly 60 on the moving component 30, the second magnetic component 52 drives the moving component 30 away from the first magnetic component 51. The elastic sleeve 62 is elastically compressed by the pressure of the stop protrusion 31. That is, the moving component 30 moves from the first position to the second position under the drive of the first drive assembly 50. Through the cooperation of the moving component 30 and the door lock assembly 40, the door 20 is switched from the closed state to the open state. Steam is discharged through the gap in the door 20, avoiding secondary dampness caused by steam condensation inside the inner tank 11. The door 20 automatically opens to release moisture according to the temperature during the drying stage, which helps to reduce the problem of moisture retention in the washing chamber 12 and the re-dampening of tableware, thereby improving the drying effect.
[0237] When the drying stage ends, the temperature inside the machine body 10 decreases, the magnetism of the first magnetic component 51 becomes weak or even non-magnetic, and the magnetic repulsion between the first magnetic component 51 and the second magnetic component 52 decreases or even becomes zero. This magnetic repulsion is less than the force exerted by the second drive assembly 60 on the moving component 30, that is, the driving force of the first drive assembly 50 on the moving component 30 is less than the force exerted by the second drive assembly 60 on the moving component 30. The elastic sleeve 62 returns to its original state from the elastic compression state. Under the action of its own elastic force, the elastic sleeve 62 pushes the stop protrusion 31, causing the moving component 30 to move from the second position to the first position as a whole. The door 20 switches from the open state to the closed state, and under the action of its own elastic force, the door 20 remains in the closed state.
