A cleaning machine

Abstract

This utility model relates to a washing machine, including an inner tank and a door. The lower edge of the door is rotatably connected to the lower edge of an opening and is used to open or close the opening. A first telescopic member is provided in the middle of the inner tank, allowing it to extend and retract vertically. A second telescopic member is provided in the middle of the door, corresponding to the first telescopic member. Both the first and second telescopic members are flexible. Clamping components are provided on the side edges of the inner tank and the door, capable of pressing and sealing the first and second telescopic members when the door is closed. With this structure, the clamping components only provide compressive force, and the sealing surface is formed by the elastic deformation of the first and second telescopic members. This structure not only provides a reliable seal when the door is closed, preventing leakage of high-temperature steam or washing water and ensuring the washing machine's reliability, but also prevents self-priming at the seal due to pressure changes in the washing chamber when opening or closing, as the compressive force disappears. This allows the door to be easily opened, making it convenient to use.

Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a cleaning machine for cleaning tableware, fruits and vegetables. Background Technology

[0002] Front-loading dishwashers are common in home kitchens. These dishwashers are usually built-in and installed in cabinets, blending seamlessly with the cabinetry for a more aesthetically pleasing look.

[0003] The applicant's earlier application CN202410864177.X, "An Installation Method for a Cleaning Machine," discloses a highly extendable cleaning machine structure, which includes an upper housing and a lower housing. The upper housing and the lower housing are connected by a telescopic structure that can extend and retract vertically. The upper housing and the lower housing are also provided with a drive mechanism that can drive the upper housing to move vertically relative to the lower housing through the telescopic structure. The top of the housing is provided with a detection structure that can cooperate with the inner top wall of the cabinet installation cavity to determine whether the installation is in place.

[0004] Using the above solution, when installing the cleaning machine, it can first be adjusted to a low height and placed in the cabinet mounting cavity. The upper cabinet is then moved upwards relative to the lower cabinet via a drive mechanism and telescopic structure. This structure meets the installation requirements of cabinets of different heights, providing greater convenience. However, for cabinets with telescopic structures, it is difficult to seal the door and cabinet together, leading to leakage of high-temperature steam or washing water. This reduces the reliability of the cleaning machine and affects its normal operation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cleaning machine that can provide a reliable seal at the telescopic structure to avoid leakage of high-temperature steam or washing water and ensure the reliability of the cleaning machine, in light of the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A cleaning machine includes an inner tank and a door. The inner tank has an opening on its front side. The lower edge of the door is rotatably connected to the lower edge of the opening and is used to open or close the opening. The inner tank has a first telescopic member in the middle that can extend and retract vertically. The door has a second telescopic member in the middle that corresponds to the first telescopic member. Both the first and second telescopic members are flexible. The side edges of the inner tank and the door are provided with clamping assemblies that can press and seal the first and second telescopic members when the door is closed.

[0008] With the above structure, the clamping component only provides the squeezing force, and the sealing surface is formed by the elastic deformation of the first and second telescopic members. This structure not only provides a reliable seal when the door is closed, preventing leakage of high-temperature steam or washing water and ensuring the high reliability of the washing machine, but also prevents the seal from self-priming due to pressure changes in the washing chamber when opening and closing, as the squeezing force disappears. This allows the door to be opened easily and is convenient to use.

[0009] Preferably, the front edge of the first telescopic member has a first pressing edge located outside the opening, and correspondingly, the side edge of the second telescopic member has a second pressing edge located outside the opening. In the closed state, the first pressing edge and the second pressing edge are elastically pressed together to form a seal. By providing the aforementioned first and second pressing edges that can be relatively pressed together, the deformation space at the seal is increased, thereby further improving the sealing effect.

[0010] Preferably, the clamping assembly includes a first clamping plate and a second clamping plate. The front edge of the first telescopic member is bent outward relative to the opening to form the first pressing edge. The first clamping plate is formed on the inner and outer walls and supports the back of the first pressing edge, thereby keeping the first pressing edge perpendicular to the inner liner sidewall. The side edge of the second telescopic member extends outward to form the second pressing edge. The second clamping plate is formed on the front wall of the door and supports the front side of the second pressing edge. The first and second clamping plates provide support for the corresponding pressing edges to ensure reliable sealing.

[0011] Preferably, the inner liner portions above and below the first telescopic member are both metal liners. The front edge of the metal liner is bent outward relative to the opening to form an upper folded edge and a lower folded edge, which respectively connect with the upper and lower edges of the first pressing edge. The lower end of the first clamping plate is integrally formed with the upper end of the lower folded edge, and the upper end of the first clamping plate is a free end that extends upward to the back of the upper folded edge. Fixing one end of the first clamping plate to the inner liner and leaving the other end as a free pressing end allows it to provide cushioning according to the pressure in the closed state, ensuring a seal while avoiding excessive compression of the telescopic member and affecting its service life.

[0012] Preferably, the sum of the thicknesses of the first and second pressing edges in their natural state is d1, and in the closed state, the distance between the first and second clamping plates is d2, where d1 < d2. This structure requires positive elastic deformation, which is beneficial for improving the sealing effect.

[0013] Preferably, the door portions above and below the second telescopic member are both metal door bodies. The side edges of these metal door bodies extend outward relative to the opening, forming upper and lower extension edges that respectively connect with the upper and lower edges of the second pressing edge. The upper end of the second clamping plate is integrally formed with the lower end of the upper extension edge, and the lower end of the second clamping plate is a free end that extends downward to the front sidewall of the lower extension edge. Fixing one end of the second clamping plate to the door body and leaving the other end as a free pressing end allows it to provide cushioning based on the pressure in the closed state, ensuring a seal while avoiding excessive compression of the telescopic member and affecting its service life. Simultaneously, the free ends of the first and second clamping plates are arranged oppositely, allowing for adaptive adjustment from the upper and lower ends of the telescopic member, which helps balance sealing performance and compression, improving structural reliability.

[0014] As an improvement, the outer edge of the first pressing edge has a serrated structure with multiple grooves, and the second pressing edge has a corrugated structure with upper and lower layers. When the door is closed, the convex peaks of the second pressing edge are precisely engaged in the grooves of the first pressing edge. This structure ensures a tight fit at the outermost elastic deformation point, which helps to further improve the sealing performance.

[0015] Preferably, the first telescopic member is a corrugated structure stacked vertically, and the first pressing edge is integrally formed with the first telescopic member, but the front and rear sidewalls of the first pressing edge are planar structures; the second telescopic member is also a corrugated structure stacked vertically, and the second pressing edge is formed by extending outward from the corrugated structure. Using the above structure facilitates manufacturing.

[0016] Compared with the prior art, the advantages of this utility model are as follows: Both the first and second telescopic components in this utility model are flexible components capable of elastic deformation. Clamping components are provided at the side edges of the inner liner and the door body to press and seal the first and second telescopic components when the door is closed. In the sealed state, the clamping components only provide extrusion force, and the sealing surface is formed by the elastic deformation of the first and second telescopic components. This structure not only provides a reliable seal when the door is closed, preventing leakage of high-temperature steam or washing water and ensuring the high reliability of the washing machine, but also prevents self-priming at the seal due to pressure changes in the washing chamber when opening and closing, as the extrusion force disappears. The door can be easily opened, making it convenient to use. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-5 As shown, the cleaning machine of this embodiment includes an inner tank 1 and a door 2. An opening 11 is provided on the front side of the inner tank 1. The lower edge of the door 2 is rotatably connected to the lower edge of the opening 11 and is used to open or close the opening 11. A first telescopic member 10 that can extend and retract vertically is provided in the middle of the inner tank 1. A second telescopic member 20 corresponding to the first telescopic member 10 is provided in the middle of the door 2. Both the first telescopic member 10 and the second telescopic member 20 are flexible parts. Clamping components 30 that can press and seal the first telescopic member 10 and the second telescopic member 20 when the door is closed are provided on the side edges of the inner tank 1 and the door 2.

[0024] With the above structure, the clamping component 30 only provides the squeezing force, and the sealing surface is formed by the elastic deformation of the first telescopic member 10 and the second telescopic member 20. This structure not only provides a reliable seal when the door is closed, preventing leakage of high-temperature steam or washing water and ensuring the reliable use of the washing machine, but also prevents the sealing point from self-priming due to changes in the pressure of the washing chamber when opening and closing, as the squeezing force disappears, the door 2 can be easily opened, making it convenient to use.

[0025] The front edge of the first telescopic member 10 has a first pressing edge 101 located outside the opening 11. Correspondingly, the side edge of the second telescopic member 20 has a second pressing edge 201 located outside the opening 11. In the closed state, the first pressing edge 101 and the second pressing edge 201 are elastically pressed together to form a seal. By providing the aforementioned first pressing edge 101 and second pressing edge 201 that can be relatively pressed together, the deformation space at the seal is increased, thereby further improving the sealing effect.

[0026] The clamping assembly 30 includes a first clamping plate 301 and a second clamping plate 302. The front edge of the first telescopic member 10 is bent outward relative to the opening 11 to form a first pressing edge 101. The first clamping plate 301 is formed on the inner and outer walls and supported on the back of the first pressing edge 101, thereby keeping the first pressing edge 101 perpendicular to the side wall of the inner liner 1. The side edge of the second telescopic member 20 extends outward to form a second pressing edge 201. The second clamping plate is formed on the front wall of the door body 2 and supported on the front side of the second pressing edge 201. The first clamping plate 301 and the second clamping plate 302 provide support for the corresponding pressing edges to ensure reliable sealing.

[0027] The inner liner 1 above and below the first telescopic member 10 is made of metal. The front edge of the metal inner liner is bent outward relative to the opening 11 to form an upper folded edge 111 and a lower folded edge 112 that respectively connect with the upper and lower edges of the first pressing edge 101. The lower end of the first clamping plate 301 is integrally formed with the upper end of the lower folded edge 112. The upper end of the first clamping plate 301 is a free end and extends upward to the back of the upper folded edge 111. By fixing one end of the first clamping plate 301 to the inner liner 1 and leaving the other end as a free pressing end, it is convenient to provide cushioning according to the pressure in the closed state, ensuring a seal while avoiding excessive compression of the telescopic member and affecting its service life.

[0028] The sum of the thicknesses of the first pressing edge 101 and the second pressing edge 201 in their natural state is d1. In the closed state, the distance between the first clamping plate 301 and the second clamping plate 302 is d2, where d1 < d2. This structure requires positive elastic deformation, which is beneficial for improving the sealing effect.

[0029] Both the upper and lower parts of the door body 2 above and below the second telescopic member 20 are metal door bodies. The side edges of the metal door body extend outward relative to the opening 11, forming an upper extension edge 21 and a lower extension edge 22 that respectively connect with the upper and lower edges of the second pressing edge 201. The upper end of the second clamping plate 302 is integrally formed with the lower end of the upper extension edge 21, and the lower end of the second clamping plate 302 is a free end that extends downward to the front side wall of the lower extension edge 22. Fixing one end of the second clamping plate 302 to the door body 2 and leaving the other end as a free pressing end allows it to provide buffering according to the pressure in the closed state, ensuring a seal while avoiding excessive compression of the telescopic member and affecting its service life. At the same time, the free ends of the first clamping plate 301 and the second clamping plate 302 are arranged opposite to each other, allowing for adaptive adjustment from the upper and lower ends of the telescopic member, which helps to balance sealing and compression, and improves structural reliability.

[0030] The outer edge of the first pressing edge 101 has a serrated structure with multiple grooves 1011, and the second pressing edge 201 has a corrugated structure with upper and lower layers. When the door is closed, the rearward arching peaks 2011 of the second pressing edge 201 fit precisely into the grooves 1011 of the first pressing edge 101. This structure ensures a tight fit at the outermost elastic deformation point, which helps to further improve the sealing performance.

[0031] The first telescopic member 10 has a corrugated structure with upper and lower layers, and the first pressing edge 101 is integrally formed with the first telescopic member 10, but the front and rear sidewalls of the first pressing edge 101 are planar structures; the second telescopic member 20 also has a corrugated structure with upper and lower layers, and the second pressing edge 201 is formed by extending outward from the corrugated structure. The above structure facilitates manufacturing.

[0032] In this embodiment, the support structure, drive structure, etc. used to support the telescopic structure are consistent with the applicant's prior application CN202410864177.X, and will not be described in detail here.

[0033] In this embodiment, both the first telescopic member 10 and the second telescopic member 20 are flexible components capable of elastic deformation. A clamping assembly 30 is provided at the side edge of the inner liner 1 and the door body 2, which can press and seal the first telescopic member 10 and the second telescopic member 20 when the door is closed. In the sealed state, the clamping assembly 30 only provides extrusion force, and the sealing surface is formed by the elastic deformation of the first telescopic member 10 and the second telescopic member 20. This structure not only provides a reliable seal when the door is closed, preventing leakage of high-temperature steam or washing water and ensuring the high reliability of the washing machine, but also prevents self-priming at the seal due to pressure changes in the washing chamber when opening and closing, as the extrusion force disappears. The door body 2 can be easily opened, making it convenient to use.
