A cleaning chamber structure for a cleaning machine and the cleaning machine itself.

Abstract

This utility model relates to a cleaning chamber structure for a cleaning machine and the cleaning machine itself. The cleaning chamber includes a cleaning inner tank, the inner cavity of which forms the cleaning chamber. Within the cleaning inner tank are arranged: guide rails; a curtain shaft; and a partition curtain. As the curtain shaft rotates, the partition curtain moves horizontally along the left and right guide rails and curls around the curtain shaft until it is completely wrapped around the curtain shaft, achieving a retracted state. In this retracted state, it can also rotate horizontally out from the curtain shaft along the left and right guide rails until it is horizontally positioned within the cleaning chamber, achieving an unfolded state. A cleaning component, rod-shaped and horizontally positioned in the left and right directions, has a length matching the left and right width of the partition curtain. Furthermore, during the process of the curtain shaft rotating and causing the partition curtain to switch between the retracted and unfolded states, it always maintains vertical contact with the bottom surface of the partition curtain. This utility model can reduce the actual cleaning space according to cleaning needs, ensuring cleaning effectiveness, avoiding water waste, and preventing dirt from being rolled into the partition curtain as the curtain shaft rotates.

Description

Technical Field

[0001] This utility model relates to the field of cleaning machines, and in particular to a cleaning chamber structure for a cleaning machine and a cleaning machine. Background Technology

[0002] With social development and technological progress, people's demands for a better life are increasing, and more and more families are starting to use dishwashers. Dishwashers not only bring convenience but also save people time. Currently, cabinet dishwashers are becoming increasingly common in the market, and existing cabinet dishwashers generally adopt a single-cavity structure. For example, there are Chinese utility model patents with patent number ZL202421524661.X (authorization announcement number CN222870465U) entitled "A Dishwasher", and Chinese invention patents with patent number ZL201910191017.2 (authorization announcement number CN111685690B) entitled "A Dishwasher Inner Tank Fixing Structure and a Dishwasher Using the Same".

[0003] If the internal volume of a single-cavity structure remains fixed, the washing space cannot be adjusted according to the number of dishes to be washed. Therefore, when the number of dishes to be washed is small, placing them in a large washing chamber not only affects the washing effect but also wastes water. Summary of the Invention

[0004] The first technical problem to be solved by this utility model is to provide a cleaning chamber structure for a cleaning machine with an adjustable actual cleaning space size, which is an improvement over the prior art.

[0005] The second technical problem to be solved by this utility model is to provide a cleaning machine with the above-mentioned cleaning chamber structure, in contrast to the prior art.

[0006] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a cleaning chamber structure for a cleaning machine, including a cleaning inner tank with a front opening, the inner cavity of which constitutes a cleaning chamber, characterized in that the cleaning inner tank is respectively provided with:

[0007] The guide rails are set horizontally on the left and right inner sides of the cleaning tank.

[0008] The curtain shaft is horizontally arranged at the rear of the cleaning chamber in the left-right direction;

[0009] The partition curtain is arranged in the left-right direction. The first end is connected to the curtain shaft along its own length direction, and the left and right sides of the second end are respectively embedded in the guide rails on the corresponding sides and can move back and forth synchronously along the guide rails. Furthermore, as the curtain shaft rotates, it can move horizontally along the left and right guide rails and curl and wrap around the curtain shaft until it is completely wrapped around the curtain shaft and becomes stored. In this stored state, it can be horizontally unscrewed from the curtain shaft along the left and right guide rails until it is horizontally separated in the washing chamber and becomes unfolded.

[0010] The cleaning component is rod-shaped and horizontally arranged in the left-right direction. Its length matches the left-right width of the partition curtain. Furthermore, during the process of the partition curtain being switched between the retracted and unfolded states by rotating the curtain shaft, it can always be in contact with the bottom surface of the partition curtain.

[0011] Furthermore, the cleaning component is positioned on the front side of the partition curtain, and in the retracted state, the cleaning component abuts against the partition curtain along its length. Thus, in the retracted state, the cleaning component can limit the movement of the partition curtain, ensuring it is stably wound and stored on the curtain shaft, preventing accidental unwinding.

[0012] Furthermore, it also includes a mounting base and an elastic element fixed in the cleaning chamber. The cleaning element is mounted on the mounting base and can move back and forth relative to the partition curtain. In the installed state, the elastic element deforms, causing the cleaning element to tend to move towards the partition curtain. The partition curtain is installed in the cleaning chamber through the mounting base, and the elastic force of the elastic element ensures that the cleaning element always abuts against the partition curtain. Compared with rigid contact, the cleaning element and the partition curtain in this invention adopt elastic contact (utilizing the elastic force of the elastic element), which can overcome the gap fluctuation between the cleaning element and the partition curtain caused by assembly errors, wear of the cleaning element, etc., ensuring the cleaning effect on the partition curtain, and also avoiding damage to the partition curtain due to excessive contact force.

[0013] Furthermore, the mounting base includes a first mounting plate disposed opposite to the aforementioned cleaning component. A mounting post extending horizontally back and forth is mounted on the first mounting plate. One end of the cleaning component has a mounting sleeve extending horizontally back and forth. The mounting post is inserted into the mounting sleeve and can move back and forth along the length of the mounting sleeve. The elastic element is a spring sleeved on the mounting post, and the spring is sandwiched between the end face of the mounting sleeve and the first mounting plate. In the installed state of the cleaning component, the elastic element is compressed, causing the cleaning component to tend to move towards the partition curtain. This allows the cleaning component to be movably mounted on the mounting base and to move back and forth relative to the partition curtain. Furthermore, in the installed state of the cleaning component, the elastic element is compressed and deformed, causing the cleaning component to tend to move towards the partition curtain.

[0014] Furthermore, a cleaning head is protruding from the outer surface of the cleaning component. This cleaning head extends along the length of the cleaning component and is opposite to the partition curtain. When the cleaning component is installed, it is always in contact with the partition curtain via the cleaning head. By providing the cleaning head, the contact pressure between the cleaning component and the partition curtain can be increased, thereby improving the cleaning effect on the partition curtain (enhancing the scraping force of dirt) and also helping to extend the service life of the cleaning component.

[0015] Furthermore, the cleaning component has a circular cross-section and the outer surface of the cleaning head is smooth, and both the cleaning component and the cleaning head are directly opposite the partition curtain. This design ensures that the cleaning component remains in contact with the partition curtain during its insertion or removal, and also prevents damage to the partition curtain.

[0016] Furthermore, in the installed state of the cleaning component, the partition curtain always abuts against the inner surface of the rear side wall of the cleaning liner. This utilizes the elastic force of the elastic component and the rigid restraint of the rear side wall of the cleaning liner to maintain a stable assembly structure between the cleaning component and the partition curtain. Moreover, the guiding effect of the inner surface of the rear side wall of the cleaning liner makes the screwing-in or screwing-out action of the partition curtain more stable.

[0017] Furthermore, each guide rail has an inwardly opening U-shaped cross-section, and the top walls of the rear ends of each guide rail are connected by a connecting wall. This connecting wall extends horizontally to the left and right and is fixed to the inner surface of the rear side wall of the cleaning liner, and is located directly above the partition curtain. This design makes the structure of the guide rails on both sides more robust, and the connecting wall also guides the partition curtain as it is screwed in or out, facilitating a smooth transition between the retracted and unfolded states.

[0018] Furthermore, a partition with a certain rigidity is provided at the second end of the partition curtain along its length. The thickness of the partition matches the inner height of each guide rail, and it can move back and forth along the guide rails on both sides under the rotational force of the curtain shaft.

[0019] Furthermore, in the retracted state, the left and right ends of the partition are clamped and positioned at the rear ends of each guide rail, while in the unfolded state, the left and right ends of the partition are clamped and positioned at the front ends of each guide rail. This partition design provides a certain degree of damping for the sliding of the partition curtain, ensuring the stability and reliability of its sliding movements. Simultaneously, the cooperation between the partition and the guide rails allows the partition curtain to be positioned in either the retracted or unfolded state.

[0020] The technical solution adopted to further solve the second technical problem mentioned above is: a cleaning machine, characterized in that it includes a cleaning chamber structure for the cleaning machine as described above.

[0021] Compared with existing technologies, the advantages of this invention are as follows: It includes a dividing curtain that can be wound and stored on a curtain shaft, and can also be unwound from the shaft and horizontally positioned within the washing chamber, thus achieving vertical separation of the internal space of the washing chamber. This way, when there are few items to be washed (e.g., tableware), the dividing curtain reduces the actual washing space, ensuring washing effectiveness while avoiding water waste. Furthermore, a cleaning component is included. As the dividing curtain rotates out (during the transition from the stored to the unfolded state) or in (during the transition from the unfolded to the stored state), the cleaning component can scrape off dirt (e.g., food residue) adhering to the dividing curtain, preventing dirt from being rolled into the dividing curtain as the shaft rotates. In addition, the cleaning component guides the rotation of the dividing curtain, allowing it to smoothly transition between the stored and unfolded states. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0031] A cleaning machine (specifically a dishwasher in this embodiment) includes, as follows: Figures 1-7 The cleaning chamber structure shown includes a front-opening inner liner 1, the inner cavity of which forms the cleaning chamber. Further, the inner liner 1 is equipped with: guide rails 2, a curtain shaft 3, a partition curtain 4, and a cleaning component 5. The guide rails 2 are horizontally positioned on the left and right inner sides of the inner liner 1. The curtain shaft 3 is horizontally positioned on the rear side of the cleaning chamber. The partition curtain 4 is positioned horizontally, with its first end connected to the curtain shaft 3 along its length, and its second end embedded in the corresponding guide rails 2 on its left and right sides, allowing it to move back and forth synchronously along the guide rails 2. As the curtain shaft 3 rotates, the partition curtain 4 moves horizontally along the left and right guide rails 2 and coils around the curtain shaft 3 until it is completely coiled and in a retracted state. In this retracted state, it can be horizontally unspinned from the curtain shaft 3 along the left and right guide rails 2 until it is horizontally positioned within the cleaning chamber and in an unfolded state. The cleaning component 5 is rod-shaped and horizontally arranged in the left-right direction. Its length matches the left-right width of the partition curtain 4. Furthermore, during the process of the partition curtain 4 switching between the retracted and unfolded states by rotating the curtain shaft 3, it can always abut against the bottom surface of the partition curtain 4.

[0032] As can be seen from the above, this utility model includes a dividing curtain 4, which can be wound and stored on the curtain shaft 3, and can also be rotated out from the curtain shaft 3 and horizontally placed in the washing chamber, thereby achieving vertical separation of the internal space of the washing chamber. When there are few items to be washed (e.g., tableware), dividing the washing chamber vertically with the dividing curtain 4 reduces the actual washing space, ensuring washing effectiveness and avoiding water waste. Furthermore, a cleaning component 5 is provided. When the dividing curtain 4 rotates out (during the transition from the stored state to the unfolded state) or in (during the transition from the unfolded state to the stored state) with the curtain shaft 3, the cleaning component 5 can scrape off dirt (e.g., food residue) adhering to the dividing curtain 4, preventing dirt from being rolled into the dividing curtain 4 as the curtain shaft 3 rotates. In addition, the cleaning component 5 guides the rotation of the dividing curtain 4, allowing it to smoothly transition between the stored and unfolded states.

[0033] Furthermore, such as Figure 2 and Figure 5 As shown, the cleaning component 5 is disposed on the front side of the partition curtain 4, and in the retracted state, the cleaning component 5 abuts against the partition curtain 4 along its length. Thus, in the retracted state, the cleaning component 5 can limit the movement of the partition curtain 4, ensuring that the partition curtain 4 is stably wound and stored on the curtain shaft 3, preventing accidental unwinding. In this embodiment, the cleaning component 5 is specifically a cotton brush.

[0034] Furthermore, the device also includes a mounting base 6 and an elastic element 7 fixed in the cleaning chamber. The cleaning element 5 is mounted on the mounting base 6, allowing it to move back and forth relative to the partition curtain 4. When the cleaning element 5 is installed, the elastic element 7 deforms, causing the cleaning element 5 to tend to move towards the partition curtain 4. The mounting base 6 enables the partition curtain 4 to be installed in the cleaning chamber, and the elastic force of the elastic element 7 ensures that the cleaning element 5 always abuts against the partition curtain 4. Compared to rigid contact, the elastic contact between the cleaning element 5 and the partition curtain 4 in this invention (utilizing the elastic force of the elastic element 7) overcomes gap fluctuations between the cleaning element 5 and the partition curtain 4 caused by assembly errors, wear of the cleaning element 5, etc., ensuring the cleaning effect of the cleaning element 5 on the partition curtain 4, and also preventing damage to the partition curtain 4 due to excessive contact force.

[0035] Specifically, such as Figure 2 , Figure 5 , Figure 6 as well as Figure 7As shown, the mounting base 6 includes a first mounting plate 61 disposed opposite to the cleaning component 5. A mounting post 63 extending horizontally back and forth is mounted on the first mounting plate 61. One end of the cleaning component 5 has a mounting sleeve 52 extending horizontally back and forth. The mounting post 63 is inserted into the mounting sleeve 52 and can move back and forth along the length of the mounting sleeve 52. The elastic element 7 is a spring sleeved on the mounting post 63, and the spring is sandwiched between the end face of the mounting sleeve 52 and the first mounting plate 61. When the cleaning component 5 is installed, the elastic element 7 is compressed, causing the cleaning component 5 to tend to move towards the partition curtain 4. This allows the cleaning component 5 to be movably mounted on the mounting base 6 and to move back and forth relative to the partition curtain 4. Furthermore, when the cleaning component 5 is installed, the elastic element 7 is compressed and deformed, causing the cleaning component 5 to tend to move towards the partition curtain 4. In this embodiment, the mounting base 6 is an integral piece and also includes a second mounting plate 62 arranged vertically in the front-back direction. The second mounting plate 62 is fixed on the inner side of the cleaning inner tank 1, and one end is fixed to the first mounting plate 61.

[0036] Preferably, such as Figure 2 As shown, a cleaning head 51 protrudes from the outer surface of the cleaning component 5. The cleaning head 51 extends along the length of the cleaning component 5 and is opposite to the partition curtain 4. When the cleaning component 5 is installed, it remains in contact with the partition curtain 4 via the cleaning head 51. The cleaning head 51 increases the contact pressure between the cleaning component 5 and the partition curtain 4, thereby improving the cleaning effect on the partition curtain 4 (enhancing the scraping force against dirt) and extending the service life of the cleaning component 5. More preferably, the cleaning component 5 has a circular cross-section, and the outer surface of the cleaning head 51 is rounded. Both the cleaning component 5 and its cleaning head 51 are directly opposite the partition curtain 4. This ensures that the cleaning component 5 maintains better contact with the partition curtain 4 during the insertion or removal of the partition curtain 4, and also prevents damage to the partition curtain 4. In this embodiment, the cleaning head 51 has a long, block-shaped cross-section, and its contact surface with the partition curtain 4 extends vertically, allowing for better contact between the cleaning head 51 and the partition curtain 4, thus ensuring a better cleaning effect.

[0037] like Figure 2 As shown, in the installed state of the cleaning component 5, the partition curtain 4 always abuts against the inner surface of the rear side wall of the cleaning inner tank 1. This utilizes the elastic force of the elastic component 7 and the rigid restraint of the rear side wall of the cleaning inner tank 1 to maintain a stable assembly structure between the cleaning component 5 and the partition curtain 4. Furthermore, the guiding effect of the inner surface of the rear side wall of the cleaning inner tank 1 makes the screwing-in or screwing-out action of the partition curtain 4 more stable. Figure 4As shown, in this embodiment, the cross-section of each of the aforementioned guide rails 2 is U-shaped with an inward opening, and the top walls of the rear ends of each guide rail 2 are connected by connecting walls 21. These connecting walls 21 extend horizontally to the left and right and are fixed to the inner surface of the rear side wall of the inner cleaning liner 1, and are located directly above the partition curtain 4. This design makes the structure of the guide rails 2 on both sides more robust, and the connecting walls 21 provide a certain guiding effect for the partition curtain 4 as it is screwed in or out, facilitating a smooth transition between the retracted and unfolded states.

[0038] like Figure 2 , Figure 5 as well as Figure 7 As shown, a partition plate 41 with a certain rigidity is provided at the second end of the partition curtain 4 along its length. The thickness of the partition plate 41 matches the inner height of each guide rail 2, and it can move back and forth along the two guide rails 2 under the rotational force of the curtain shaft 3. Furthermore, in the retracted state, the left and right ends of the partition plate 41 are clamped and positioned in the rear end of each guide rail 2, while in the unfolded state, the left and right ends of the partition plate 41 are clamped and positioned in the front end of each guide rail 2. Thus, by setting the partition plate 41, a certain damping effect is provided for the screwing in and out of the partition curtain 4, ensuring the stability and reliability of the screwing in and out actions of the partition curtain 4. Simultaneously, the cooperation between the partition plate 41 and each guide rail 2 allows the partition curtain 4 to be positioned in either the retracted or unfolded state.

[0039] like Figure 2 As shown, a drive motor 8 is mounted on the outer surface of the aforementioned inner cleaning tank 1. The output shaft 81 of the drive motor 8 extends horizontally and into the inner cleaning tank 1, and is connected to the aforementioned curtain shaft 3, as shown. Figure 6 As shown. In this embodiment, specifically, the drive motor 8 is fixed to the left outer side of the cleaning inner tank 1 via the motor mount 9.
