Description

Technical Field

[0001] This application relates to the technical field of household appliances, and particularly to a dishwasher. Background Art

[0002] A dishwasher is a modern kitchen appliance mainly used for automatically cleaning tableware such as bowls, plates, cups, forks and knives. The dishwasher combines high-temperature water flow and detergent to effectively remove oil stains and food residues on the tableware, and at the same time kill bacteria, making the tableware cleaner and more hygienic.

[0003] When the user closes the door of the dishwasher, the situation where the door is not fully closed often occurs, and there is a gap between the door and the cabinet. In this case, the washing water in the dishwasher may flow out from the gap, resulting in a poor user experience. It is also possible that the user has fully closed the door, but for safety reasons, opens the door and closes it again, which easily causes excessive use of the door and the lock body, reducing the service life of the dishwasher.

[0004] Therefore, the problem that the user cannot determine whether the door of the dishwasher is closed is what needs to be solved now. Summary of the Utility Model

[0005] This application provides a dishwasher for solving the problem that the user cannot determine whether the door of the dishwasher is closed.

[0006] This application provides a dishwasher, including: a cabinet, a locking structure, a door body, and a lock tongue. An accommodation compartment is formed in the cabinet, and an opening communicating with the accommodation compartment is provided on the accommodation compartment; the locking structure is arranged on the cabinet, and the locking structure includes: a limiting member and an elastic member. The limiting member is movably connected to the cabinet. The limiting member includes: a first clamping arm and a second clamping arm arranged along a first direction. A clamping gap is formed between the first clamping arm and the second clamping arm; the elastic member is used for elastically supporting the first clamping arm and the second clamping arm; the door body is used for opening or closing the opening, and an installation groove is provided on the door body; at least part of the lock tongue is arranged in the installation groove, and there is an installation gap between the lock tongue and the side wall of the installation groove along a second direction in the installation groove; the second direction is the arrangement direction of the door body and the accommodation compartment when the door body is closed, and the second direction is perpendicular to the first direction; the lock tongue includes: a sliding portion and a guiding portion; the guiding portion is connected to the sliding portion, and a guiding inclined surface is provided on the end surface of the guiding portion away from the sliding portion; when closing the door body, when the sliding portion passes through the clamping gap, the first clamping arm and the second clamping arm move away from each other under the action of the sliding portion, so that the elastic member deforms; until when the sliding portion completely passes through the clamping gap and the guiding portion starts to move out of the clamping gap, under the action of the restoring force of the elastic member, the first clamping arm and / or the second clamping arm is pushed to act on the guiding inclined surface, so that the first clamping arm and the second clamping arm move relatively, and the lock tongue is pushed to move towards the installation gap.

[0007] In this way, when the user needs to close the door of the dishwasher, first, the locking tongue abuts against the locking structure on the cabinet body. Then, the sliding part of the locking tongue partially extends into the clamping gap formed between the first clamping arm and the second clamping arm. As the door continues to be pushed towards the cabinet body, the sliding part presses against the first clamping arm and the second clamping arm, causing the first clamping arm and the second clamping arm to displace, and further causing the elastic member to deform, so that the first clamping arm and the second clamping arm clamp the locking tongue, and the part of the locking tongue located in the installation groove abuts against the side wall of the installation groove. Continuing to push the door towards the cabinet body, the sliding part slides between the first clamping arm and the second clamping arm in the second direction, and the first clamping arm and the second clamping arm displace in the second direction, further pushing the door towards the cabinet body. The sliding part passes through the first clamping arm and the second clamping arm, and the guiding part abuts against the first clamping arm and the second clamping arm. The first clamping arm and the second clamping arm gradually contract in the first direction under the action of the restoring force provided by the elastic member. The force of the first clamping arm and the second clamping arm acts on the guiding inclined surface of the guiding part, causing the guiding part to displace in the second direction. At this time, the first clamping arm and the second clamping arm limit the locking tongue, and further limit the door, so that the door closes the opening of the cabinet body. When the guiding part displaces in the second direction, the locking tongue collides with the side wall of the installation groove and makes a sound. The user can judge whether the dishwasher is completely closed according to the sound. When the user hears the sound made by the collision between the locking tongue and the side wall of the installation groove, it indicates that the first clamping arm and the second clamping arm limit the locking tongue, so that the door closes the opening of the cabinet body.

[0008] In some embodiments of the present application, the locking tongue further includes: a base, which is arranged in the installation groove. The base has an installation gap with the side wall of the installation groove in the second direction in the installation groove. Both the sliding part and the guiding part are connected to the base; in the second direction, the length of the sliding part gradually decreases in the first direction.

[0009] In this way, setting the base in the installation groove and having an installation gap between the base and the side wall of the installation groove in the second direction in the installation groove can make the base and the dishwasher make a sound when closing the door. Setting the sliding part such that its length gradually decreases in the first direction in the second direction can make the end surface of the sliding part in contact with the first clamping arm and the second clamping arm be an inclined surface, making it easier for the first clamping arm and the second clamping arm to slide, saving effort for the user when closing the door of the dishwasher, and improving the user experience.

[0010] In some embodiments of the present application, the locking tongue further includes: a guiding member, which is connected to the sliding part. The guiding member is arranged on the side of the sliding part away from the guiding part. The length of the guiding member in the first direction is less than or equal to the length of the clamping gap in the first direction.

[0011] Thus, when the user closes the door, if there is a certain error between the lock tongue and the locking component, it will cause the sliding part to be unable to enter the gap between the first clamping arm and the second clamping arm, making it impossible for the user to close the door smoothly. Connecting the guiding part to the sliding part, and the length of the guiding part in the first direction is less than or equal to the length of the clamping gap in the first direction, which can make the guiding part enter the gap between the first clamping arm and the second clamping arm first. Even if there is a certain error between the lock tongue and the locking component, and the length of the guiding part in the first direction is less than or equal to the length of the clamping gap in the first direction, it can make the guiding part easier to enter the gap between the first clamping arm and the second clamping arm, and then make the lock tongue easier to enter the gap between the first clamping arm and the second clamping arm, making it smoother for the user to close the dishwasher door and improving the user experience.

[0012] In some embodiments of the present application, the guiding part has a guiding surface, and the guiding surface is arc-shaped.

[0013] In this way, when the sliding part passes through the first clamping arm and the second clamping arm, the guiding part abuts against the first clamping arm and the second clamping arm. Under the action of the restoring force provided by the elastic part, the first clamping arm and the second clamping arm gradually contract along the first direction. When the forces of the first clamping arm and the second clamping arm act on the guiding inclined surface of the guiding part, setting the guiding surface as arc-shaped can make the first clamping arm and the second clamping arm better limit the guiding part, and then make the locking structure limit the lock tongue more firmly, avoiding the lock tongue falling off from the locking structure during the operation of the dishwasher.

[0014] In some embodiments of the present application, the door body further includes: a door liner for opening or closing the opening, with a limiting hole provided on the door liner, and at least a part of the lock tongue extends out of the limiting hole; a mounting part connected to the door liner, the mounting part is arranged on the side of the door liner away from the cabinet body, and a mounting groove is provided on the mounting part. The limiting hole and the mounting part are used to limit the lock tongue.

[0015] In this way, the limiting hole and the mounting part are used to limit the lock tongue, which can prevent the lock tongue from falling off from the mounting part when the user opens or closes the door body, resulting in the user being unable to close the cabinet body and affecting the user experience.

[0016] In some embodiments of the present application, the mounting groove further includes: a guiding strip provided on the side wall of the mounting groove; the lock tongue further includes: a guiding groove provided on the side of the base. The guiding strip can slide in the guiding groove along the second direction and the third direction, and the third direction is perpendicular to both the first direction and the second direction.

[0017] In this way, a guiding bar is arranged in the installation groove, and a guiding groove is arranged on the side of the base, enabling the guiding bar to slide in the guiding groove along both the second direction and the third direction. When installing the lock tongue, the guiding groove has a guiding effect, enabling the lock tongue to enter the installation groove more smoothly, thereby improving the installation efficiency.

[0018] In some embodiments of the present application, the base, the sliding part, the guiding part, and the guiding member are of an integral structure.

[0019] In this way, making the base, the sliding part, the guiding part, and the guiding member of an integral structure can make the connection between the base, the sliding part, the guiding part, and the guiding member more firm, avoiding the breakage at the joints between the base, the sliding part, the guiding part, and the guiding member during use, which may cause the user to be unable to close the box body and affect the user experience.

[0020] In some embodiments of the present application, the ends of the first clamping arm and the second clamping arm far from the box body are both arc-shaped surfaces.

[0021] In this way, setting the ends of the first clamping arm and the second clamping arm far from the box body as arc-shaped surfaces can make it easier for the lock tongue to enter the gap between the first clamping arm and the second clamping arm. When the first clamping arm and the second clamping arm cooperate with the sliding part or the guiding part, it can make the first clamping arm and the second clamping arm slide more easily, thereby making it more labor-saving for the user to close the dishwasher door body and improving the user experience.

[0022] In some embodiments of the present application, the end of the first clamping arm far from the box body extends towards the second clamping arm, and the end of the second clamping arm far from the box body extends towards the first clamping arm.

[0023] In this way, when the sliding part passes through the first clamping arm and the second clamping arm, the guiding part abuts against the first clamping arm and the second clamping arm. Under the action of the restoring force provided by the elastic member, the first clamping arm and the second clamping arm gradually contract along the first direction. When the force of the first clamping arm and the second clamping arm acts on the guiding inclined surface of the guiding part, setting the guiding surface as an arc can enable the first clamping arm and the second clamping arm to better limit the guiding part. Extending the end of the first clamping arm far from the box body towards the second clamping arm and the end of the second clamping arm far from the box body towards the first clamping arm can make the locking structure limit the lock tongue more firmly, avoiding the lock tongue falling off from the locking structure during the operation of the dishwasher.

[0046] A dishwasher is a modern kitchen appliance mainly used for automatically cleaning tableware, such as bowls, plates, cups, forks, and knives. The dishwasher effectively removes oil stains and food residues on the tableware through the combination of high-temperature water flow and detergent, while killing bacteria, making the tableware cleaner and more hygienic.

[0047] When the user closes the door of the dishwasher, it often happens that the door is not fully closed, and there is a gap between the door and the cabinet body. In this case, the washing water in the dishwasher may flow out from the gap, resulting in a poor user experience. It is also possible that the user has fully closed the door, but for safety reasons, opens the door and closes it again, which is likely to cause excessive use of the door and the lock body and reduce the service life of the dishwasher. The problem that the user cannot determine whether the door of the dishwasher is closed needs to be solved now.

[0048] To solve the above problems, the present application provides a dishwasher 100, as Figure 1 and Figure 2 shown, including: a cabinet body 10, a locking structure 20, a door body 30 and a lock tongue 40. An accommodation chamber 11 is formed in the cabinet body 10, and an opening 12 communicating with the accommodation chamber 11 is provided on the accommodation chamber 11. The locking structure 20 is arranged on the cabinet body 10, and the locking structure 20 includes: a limiting member 21 and a reset member 22. The limiting member 21 is movably connected to the cabinet body 10; the reset member 22 is connected to the limiting member 21 and is used to provide a reset force to the limiting member 21.

[0049] Among them, the reset member 22 can be an elastic member or a magnetic member, and the present application does not limit this.

[0050] In addition, the limiting member 21 is used to limit the lock tongue 40. The limiting member 21 can adopt a claw shape or a retractable limiting protrusion, etc., and the present application does not limit this.

[0051] As Figure 1 , Figure 3 , Figure 4 and Figure 7 shown, the door body 30 is used to open or close the opening 12, and an installation groove 31 is provided on the door body 30. At least part of the lock tongue 40 is arranged in the installation groove 31. The lock tongue 40 has an installation gap 311 with the side wall of the installation groove 31 along a second direction in the installation groove 31. The second direction is the arrangement direction of the door body 30 and the accommodation chamber 11 when the door body 30 is closed. The lock tongue 40 includes: a sliding part 41 and a guiding part 42. The guiding part 42 is connected to the sliding part 41, and a guiding inclined surface 421 is provided on the end surface of the guiding part 42 away from the sliding part 41.

[0052] Among them, the angle between the guiding inclined surface 421 and the first direction can be an obtuse angle, a right angle or an acute angle, etc., and the present application does not limit this.

[0053] During the closing process of the door body 30, the lock tongue 40 moves towards the opening 12 to drive the limiting member 21 to move, and a force is applied to the restoring member 22. When the locking structure 20 cooperates with the sliding portion 41, the limiting member 21 applies a restoring force to the lock tongue 40 under the action of the restoring member 22. When the locking structure 20 cooperates with the guiding portion 42, the limiting member 21 applies a restoring force to the guiding portion 42 under the action of the restoring member 22, so that the lock tongue 40 moves in the second direction.

[0054] In this way, when the user needs to close the door body 30 of the dishwasher 100, first, the lock tongue 40 abuts against the locking structure 20 on the cabinet 10, and then a part of the sliding portion 41 of the lock tongue 40 extends between the limiting members 21. As the door body 30 continues to be pushed towards the cabinet 10, the sliding portion 41 presses the limiting members 21, causing the limiting members 21 to displace, and further causing the restoring member 22 to deform, so that the limiting members 21 clamp the lock tongue 40, and the part of the lock tongue 40 located in the mounting groove 31 abuts against the side wall of the mounting groove 31. Continuing to push the door body 30 towards the cabinet 10, the sliding portion 41 slides between the limiting members 21 in the second direction, and the limiting members 21 displace in the second direction, further pushing the door body 30 towards the cabinet 10. The sliding portion 41 passes through the limiting members 21, and the guiding portion 42 abuts against the limiting members 21. The limiting members 21 gradually contract under the action of the restoring force provided by the restoring member 22, and the force of the limiting members 21 acts on the guiding inclined surface 421 of the guiding portion 42, causing the guiding portion 42 to displace in the second direction. At this time, the limiting members 21 limit the lock tongue 40, and further limit the door body 30, so that the door body 30 closes the opening 12 of the cabinet 10. When the guiding portion 42 displaces in the second direction, the lock tongue 40 collides with the side wall of the mounting groove 31 and makes a sound. The user can judge whether the dishwasher 100 is completely closed according to the sound. When the user hears the sound made by the collision between the lock tongue 40 and the side wall of the mounting groove 31, it indicates that the limiting members 21 limit the lock tongue 40, so that the door body 30 closes the opening 12 of the cabinet 10.

[0055] In some other embodiments of the present application, such as Figure 1 and Figure 3 as shown, a dishwasher 100 is provided, including: a cabinet 10, a locking structure 20, a door body 30 and a lock tongue 40. An accommodation chamber 11 is formed in the cabinet 10, and an opening 12 communicating with the accommodation chamber 11 is formed on the accommodation chamber 11.

[0056] In addition, a washing chamber is formed in the accommodation chamber 11, and a bowl basket is further arranged in the washing chamber. The bowl basket can be used to place tableware. Exemplarily, the bowl basket can be used to place larger tableware such as bowls, glass cups, and goblets. The number of the bowl baskets can be one or multiple, and the number of the bowl baskets can be set according to the size of the dishwasher 100. When there are multiple bowl baskets, the multiple bowl baskets can be arranged at intervals in the vertical direction. The connection relationship between the bowl basket and the washing chamber can be fixed connection, detachable connection, sliding connection, etc., and the present application does not limit this.

[0057] Among them, as Figure 1 , Figure 2 , Figure 5 and Figure 6 shown, the locking structure 20 is arranged on the box body 10. The locking structure 20 includes: a limiting member 21 and an elastic member 23. The limiting member 21 is movably connected to the box body 10. The limiting member 21 includes: a first clamping arm 211 and a second clamping arm 212 arranged along a first direction. A clamping gap is formed between the first clamping arm 211 and the second clamping arm 212; the elastic member 23 is used for elastically supporting the first clamping arm 211 and the second clamping arm 212.

[0058] It should be noted that the elastic member 23 can be a spring or an elastic rubber, etc., and the present application does not limit this.

[0059] The first clamping arm 211 and the second clamping arm 212 are arranged along the first direction, and the first clamping arm 211 and the second clamping arm 212 can move relative to each other in the first direction, that is, the first clamping arm 211 and the second clamping arm 212 can move closer to or away from each other in the first direction. The first clamping arm 211 and the second clamping arm 212 can be connected to the same elastic member 23, and the first clamping arm 211 and the second clamping arm 212 can also be connected to different elastic members 23. The present application does not limit this.

[0060] When the elastic member 23 is in a relaxed state, a clamping gap is formed between the first clamping arm 211 and the second clamping arm 212. When the first clamping arm 211 and the second clamping arm 212 can move closer to or away from each other in the first direction, the elastic member 23 undergoes compression or tensile deformation.

[0061] Among them, the door body 30 is used to open or close the opening 12, and an installation groove 31 is formed on the door body 30; at least part of the locking tongue 40 is arranged in the installation groove 31, and there is an installation gap 311 between the locking tongue 40 and the side wall of the installation groove 31 in the second direction in the installation groove 31; the second direction is the arrangement direction of the door body 30 and the accommodation chamber 11 when the door body 30 is closed, and the second direction is perpendicular to the first direction.

[0062] In addition, the lock tongue 40 and the installation groove 31 can be made of metal, plastic, or other materials that can produce sounds when struck. The lock tongue 40 and the installation groove 31 can be made of the same material, or they can be made of different materials. This application does not make any limitations in this regard.

[0063] Among them, as Figure 1 , Figure 7 and Figure 8 shown, the lock tongue 40 includes: a sliding portion 41 and a guiding portion 42; the guiding portion 42 is connected to the sliding portion 41, and a guiding inclined surface 421 is provided on the end surface of the guiding portion 42 away from the sliding portion 41; when closing the door body 30, when the sliding portion 41 passes through the clamping gap, the first clamping arm 211 and the second clamping arm 212 move away from each other under the action of the sliding portion 41, so that the elastic member 23 undergoes elastic deformation; until when the sliding portion 41 completely passes through the clamping gap and the guiding portion 42 starts to move out of the clamping gap, under the action of the restoring force of the elastic member 23, the first clamping arm 211 and / or the second clamping arm 212 are pushed to act on the guiding inclined surface 421, so that the first clamping arm 211 and the second clamping arm 212 move relatively, and the lock tongue 40 is pushed towards the installation gap 311.

[0064] In addition, the angle between the guiding inclined surface 421 and the first direction can be an obtuse angle, a right angle, an acute angle, etc. This application does not make any limitations in this regard.

[0065] In this way, when the user needs to close the door body 30 of the dishwasher 100, first, the locking tongue 40 abuts against the locking structure 20 on the cabinet body 10. Then, the sliding portion 41 of the locking tongue 40 partially extends into the clamping gap formed between the first clamping arm 211 and the second clamping arm 212. As the door body 30 continues to be pushed towards the cabinet body 10, the sliding portion 41 presses the first clamping arm 211 and the second clamping arm 212, causing the first clamping arm 211 and the second clamping arm 212 to displace, and further causing the elastic member 23 to deform, so that the first clamping arm 211 and the second clamping arm 212 clamp the locking tongue 40, and the portion of the locking tongue 40 located in the mounting groove 31 abuts against the side wall of the mounting groove 31. Continuing to push the door body 30 towards the cabinet body 10, the sliding portion 41 slides between the first clamping arm 211 and the second clamping arm 212 in the second direction, and the first clamping arm 211 and the second clamping arm 212 displace in the second direction, further pushing the door body 30 towards the cabinet body 10. The sliding portion 41 passes through the first clamping arm 211 and the second clamping arm 212, and the guiding portion 42 abuts against the first clamping arm 211 and the second clamping arm 212. The first clamping arm 211 and the second clamping arm 212 gradually contract in the first direction under the action of the restoring force provided by the elastic member 23. The forces of the first clamping arm 211 and the second clamping arm 212 act on the guiding inclined surface 421 of the guiding portion 42, causing the guiding portion 42 to displace in the second direction. At this time, the first clamping arm 211 and the second clamping arm 212 limit the locking tongue 40, and further limit the door body 30, so that the door body 30 closes the opening 12 of the cabinet body 10. When the guiding portion 42 displaces in the second direction, the locking tongue 40 collides with the side wall of the mounting groove 31 and makes a sound. The user can judge whether the dishwasher 100 is completely closed according to the sound. When the user hears the sound made by the collision between the locking tongue 40 and the side wall of the mounting groove 31, it indicates that the first clamping arm 211 and the second clamping arm 212 limit the locking tongue 40, so that the door body 30 closes the opening 12 of the cabinet body 10.

[0066] In a possible structural design, as Figure 1 、 Figure 7 and Figure 8 shown, a guiding inclined surface 421 is provided on the end surface of the guiding portion 42 far away from the sliding portion 41. The guiding inclined surface 421 includes a first inclined surface and a second inclined surface. The first inclined surface and the second inclined surface are symmetrically arranged, and the first clamping arm 211 and the second clamping arm 212 are symmetrically arranged.

[0067] Thus, when the sliding part 41 passes through the first clamping arm 211 and the second clamping arm 212, the guiding part 42 abuts against the first clamping arm 211 and the second clamping arm 212. Under the action of the restoring force provided by the elastic member 23, the first clamping arm 211 and the second clamping arm 212 gradually contract along the first direction. The forces of the first clamping arm 211 and the second clamping arm 212 act on the guiding inclined surface 421 of the guiding part 42, that is, the first clamping arm 211 and the second clamping arm 212 act together on the first inclined surface and the second inclined surface. The first inclined surface and the second inclined surface are symmetrically arranged, and the first clamping arm 211 and the second clamping arm 212 are symmetrically arranged, which can make the first clamping arm 211 and the second clamping arm 212 more stable when clamping the guiding part 42. When the guiding part 42 is jointly acted on by the first clamping arm 211 and the second clamping arm 212, the guiding part 42 can be displaced in the second direction, causing the locking tongue 40 to collide with the side wall of the installation groove 31. When the user hears the sound of the collision between the locking tongue 40 and the side wall of the installation groove 31, it indicates that the first clamping arm 211 and the second clamping arm 212 limit the locking tongue 40, so that the door body 30 closes the opening 12 of the box body 10, and the first clamping arm 211 and the second clamping arm 212 can more stably limit the locking tongue 40.

[0068] In some embodiments of the present application, as Figure 1 、 Figure 7 and Figure 8 shown, the locking tongue 40 further includes: a base 43, the base 43 is arranged in the installation groove 31, and the base 43 has an installation gap 311 with the side wall of the installation groove 31 in the second direction in the installation groove 31. Both the sliding part 41 and the guiding part 42 are connected to the base 43; in the second direction, the length of the sliding part 41 gradually decreases in the first direction.

[0069] Wherein, the shapes of the base 43 and the installation groove 31 can be rectangular, triangular or circular, etc. The shapes of the base 43 and the installation groove 31 can be the same, or the shapes of the base 43 and the installation groove 31 can be different. The present application does not limit this.

[0070] In this way, by arranging the base 43 in the installation groove 31 and the base 43 having an installation gap 311 with the side wall of the installation groove 31 in the second direction in the installation groove 31, the base 43 and the dishwasher 100 can make a sound when the door is closed. By setting the sliding part 41 such that its length gradually decreases in the first direction in the second direction, the end surface of the sliding part 41 in contact with the first clamping arm 211 and the second clamping arm 212 can be an inclined surface, making it easier for the first clamping arm 211 and the second clamping arm 212 to slide, and making it more labor-saving for the user to close the door body 30 of the dishwasher 100, thus improving the user experience.

[0071] In a possible structural design, the base 43 has an installation gap 311 with the side wall of the installation groove 31 in the second direction within the installation groove 31, and the base 43 also has an installation gap 311 with the side walls of the installation groove 31 in other directions.

[0072] In this way, when the guiding portion 42 abuts against the first clamping arm 211 and the second clamping arm 212, the first clamping arm 211 and the second clamping arm 212 gradually contract along the first direction under the action of the restoring force provided by the elastic member 23. The forces of the first clamping arm 211 and the second clamping arm 212 act on the guiding inclined surface 421 of the guiding portion 42. When the guiding portion 42 is displaced in the second direction, installation gaps 311 are provided in all directions between the base 43 and the installation groove 31, which can make the contact area between the base 43 and the installation groove 31 larger, making the collision sound louder, enabling the user to more easily distinguish whether the door body 30 is closed. And providing installation gaps 311 in all directions between the base 43 and the installation groove 31 can make the assembly of the base 43 and the installation groove 31 easier, improving the production efficiency.

[0073] In a possible structural design, as Figure 1 、 Figure 7 and Figure 8 shown, in the second direction, the length of the sliding portion 41 gradually decreases in the first direction, and the sliding portion 41 has a symmetric structure.

[0074] In this way, when the user needs to close the door body 30 of the dishwasher 100, first, the locking tongue 40 abuts against the locking structure 20 on the cabinet 10. Then, a part of the sliding portion 41 of the locking tongue 40 extends into the clamping gap formed between the first clamping arm 211 and the second clamping arm 212. When the sliding portion 41 presses the first clamping arm 211 and the second clamping arm 212, causing the first clamping arm 211 and the second clamping arm 212 to be displaced, and further causing the elastic member 23 to deform, so that the first clamping arm 211 and the second clamping arm 212 clamp the locking tongue 40, and the part of the locking tongue 40 located in the installation groove 31 abuts against the side wall of the installation groove 31. Setting the sliding portion 41 to have a symmetric structure can make the first clamping arm 211 and the second clamping arm 212 more stable when clamping the sliding portion 41, avoiding the overall offset of the locking tongue 40 due to uneven force, resulting in the locking structure 20 being unable to limit the locking tongue 40 and causing the door body 30 to be unable to be closed.

[0075] In some embodiments of the present application, as Figure 1 、 Figure 8 and Figure 9 shown, the locking tongue 40 further includes: a guiding member 44, connected to the sliding portion 41. The guiding member 44 is arranged on the side of the sliding portion 41 away from the guiding portion 42, and the length of the guiding member 44 in the first direction is less than or equal to the length of the clamping gap in the first direction.

[0076] Thus, when the user closes the door, if there is a certain error between the lock tongue 40 and the locking component, it will cause the sliding part 41 to be unable to enter the gap between the first clamping arm 211 and the second clamping arm 212, preventing the user from smoothly closing the door body 30. By connecting the guiding part 44 with the sliding part 41, and the length of the guiding part 44 in the first direction is less than or equal to the length of the clamping gap in the first direction, the guiding part 44 can first enter the gap between the first clamping arm 211 and the second clamping arm 212. Even if there is a certain error between the lock tongue 40 and the locking component, and the length of the guiding part 44 in the first direction is less than or equal to the length of the clamping gap in the first direction, it can make the guiding part 44 easier to enter the gap between the first clamping arm 211 and the second clamping arm 212, and then make the lock tongue 40 easier to enter the gap between the first clamping arm 211 and the second clamping arm 212, making it smoother for the user to close the door body 30 of the dishwasher 100 and improving the user experience.

[0077] In some embodiments of the present application, such as Figure 1 、 Figure 7 and Figure 8 shown, the guiding part 42 has a guiding surface, and the guiding surface is arc-shaped.

[0078] In this way, when the sliding part 41 passes through the first clamping arm 211 and the second clamping arm 212, the guiding part 42 abuts against the first clamping arm 211 and the second clamping arm 212. Under the action of the restoring force provided by the elastic member 23, the first clamping arm 211 and the second clamping arm 212 gradually contract along the first direction. When the force of the first clamping arm 211 and the second clamping arm 212 acts on the guiding inclined surface 421 of the guiding part 42, setting the guiding surface as arc-shaped can make the first clamping arm 211 and the second clamping arm 212 better limit the guiding part 42, and then make the locking structure 20 limit the lock tongue 40 more firmly, preventing the lock tongue 40 from falling off the locking structure 20 during the operation of the dishwasher 100.

[0079] In a possible structural design, such as Figure 1 、 Figure 7 and Figure 8 shown, the guiding part 42 has a guiding surface, the guiding surface is arc-shaped, and the arc is concave towards the inside of the guiding part 42.

[0080] In this way, when the sliding part 41 passes through the first clamping arm 211 and the second clamping arm 212, the guiding part 42 abuts against the first clamping arm 211 and the second clamping arm 212, making the first clamping arm 211 and the second clamping arm 212 located in the depression of the guiding part 42, making the locking structure 20 limit the lock tongue 40 more firmly, preventing the lock tongue 40 from falling off the locking structure 20 during the operation of the dishwasher 100.

[0081] In some embodiments of the present application, such as Figure 1 , Figure 10 and Figure 11 shown, the door body 30 further includes: a door liner 32 and a mounting portion 33. The door liner 32 is used to open or close the opening 12. A limiting hole 321 is provided on the door liner 32, and at least a part of the locking tongue 40 extends out of the limiting hole 321; the mounting portion 33 is connected to the door liner 32, the mounting portion 33 is arranged on the side of the door liner 32 away from the box body 10, a mounting groove 31 is provided on the mounting portion 33, and the limiting hole 321 and the mounting portion 33 are used to limit the locking tongue 40.

[0082] In this way, the limiting hole 321 and the mounting portion 33 are used to limit the locking tongue 40, which can prevent the locking tongue 40 from falling off from the mounting portion 33 when the user opens or closes the door body 30, resulting in the user being unable to close the box body 10 and affecting the user experience.

[0083] Among them, the connection method between the mounting portion 33 and the inner liner can be bolt connection, riveting or snap connection, etc., and the present application does not limit this.

[0084] In a possible structural design, the limiting hole 321 cooperates with the mounting portion 33. The sliding portion 41, the guiding portion 42 and the guiding member 44 of the locking tongue 40 extend out of the limiting hole 321, the base 43 of the locking tongue 40 is located in the mounting groove 31 of the mounting portion 33, there is a gap between the hole wall of the limiting hole 321 and the sliding portion 41, the guiding portion 42 and the guiding member 44 of the locking tongue 40, and the base 43 of the locking tongue 40 cannot pass through the limiting hole 321.

[0085] In this way, the limiting hole 321 can limit the base 43 of the locking tongue 40, which can prevent the locking tongue 40 from falling off from the mounting portion 33 when the user opens or closes the door body 30, resulting in the user being unable to close the box body 10 and affecting the user experience. And there is a gap between the hole wall of the limiting hole 321 and the sliding portion 41, the guiding portion 42 and the guiding member 44 of the locking tongue 40, which can enable the locking tongue 40 to displace when cooperating with the locking structure 20, so that the base 43 of the locking tongue 40 collides with the mounting groove 31. When the user hears the sound of the collision between the locking tongue 40 and the side wall of the mounting groove 31, it indicates that the first clamping arm 211 and the second clamping arm 212 limit the locking tongue 40, so that the door body 30 closes the opening 12 of the box body 10, and enables the first clamping arm 211 and the second clamping arm 212 to more stably limit the locking tongue 40.

[0086] In some embodiments of the present application, such as Figure 1 , Figure 12 and Figure 13As shown, the installation groove 31 further includes: a guide strip 312, which is arranged on the side wall of the installation groove 31; the locking tongue 40 further includes: a guide groove 431, which is arranged on the side of the base 43, and the guide strip 312 can slide in the guide groove 431 along both the second direction and the third direction, and the third direction is perpendicular to both the first direction and the second direction.

[0087] In this way, by arranging the guide strip 312 in the installation groove 31 and the guide groove 431 on the side of the base 43, so that the guide strip 312 can slide in the guide groove 431 along both the second direction and the third direction, when installing the locking tongue 40, the guide groove 431 has a guiding effect, enabling the locking tongue 40 to enter the installation groove 31 more smoothly, thereby improving the installation efficiency.

[0088] In some other embodiments of the present application, the installation groove 31 may include: a guide groove 431, which is arranged on the side wall of the installation groove 31; the locking tongue 40 may further include: a guide strip 312, which is arranged on the side of the base 43, and the guide strip 312 can slide in the guide groove 431 along both the second direction and the third direction, and the third direction is perpendicular to both the first direction and the second direction.

[0089] In this way, by arranging the guide groove 431 in the installation groove 31 and the guide strip 312 on the side of the base 43, so that the guide strip 312 can slide in the guide groove 431 along both the second direction and the third direction, when installing the locking tongue 40, the guide groove 431 has a guiding effect, enabling the locking tongue 40 to enter the installation groove 31 more smoothly, thereby improving the installation efficiency.

[0090] Wherein, there may be multiple guide strips 312 and guide grooves 431, and the present application does not limit this.

[0091] In some embodiments of the present application, the base 43, the sliding part 41, the guiding part 42 and the guiding member 44 are of an integral structure.

[0092] In this way, making the base 43, the sliding part 41, the guiding part 42 and the guiding member 44 of an integral structure can make the connection between the base 43, the sliding part 41, the guiding part 42 and the guiding member 44 more firm, and avoid the breakage at the connection between the base 43, the sliding part 41, the guiding part 42 and the guiding member 44 during use, resulting in the user being unable to close the box body 10 and affecting the user experience.

[0093] In some embodiments of the present application, as Figure 14 and Figure 15 shown, the ends of the first clamping arm 211 and the second clamping arm 212 far from the box body 10 are both arc-shaped surfaces.

[0094] In this way, by setting the ends of the first clamping arm 211 and the second clamping arm 212 away from the cabinet 10 as arc surfaces, the lock tongue 40 can more easily enter the gap between the first clamping arm 211 and the second clamping arm 212. When the first clamping arm 211 and the second clamping arm 212 cooperate with the sliding part 41 or the guiding part 42, the first clamping arm 211 and the second clamping arm 212 can slide more easily, thereby making it more labor-saving for the user to close the door body 30 of the dishwasher 100 and improving the user experience.

[0095] In some embodiments of the present application, as Figure 14 and Figure 16 shown, the end of the first clamping arm 211 away from the cabinet 10 extends towards the second clamping arm 212, and the end of the second clamping arm 212 away from the cabinet 10 extends towards the first clamping arm 211.

[0096] In this way, when the sliding part 41 passes through the first clamping arm 211 and the second clamping arm 212, the guiding part 42 abuts against the first clamping arm 211 and the second clamping arm 212, and the first clamping arm 211 and the second clamping arm 212 gradually contract along the first direction under the action of the restoring force provided by the elastic member 23. When the force of the first clamping arm 211 and the second clamping arm 212 acts on the guiding inclined surface 421 of the guiding part 42, setting the guiding surface as an arc can enable the first clamping arm 211 and the second clamping arm 212 to better limit the guiding part 42. The end of the first clamping arm 211 away from the cabinet 10 extends towards the second clamping arm 212, and the end of the second clamping arm 212 away from the cabinet 10 extends towards the first clamping arm 211, thereby making the locking structure 20 limit the lock tongue 40 more firmly and preventing the lock tongue 40 from falling off the locking structure 20 during the operation of the dishwasher 100.

[0097] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
