Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and specifically provides a door assembly for a cleaning equipment and a cleaning equipment. Background Technology

[0002] A dishwasher is a device that sprays cold or hot water onto bowls, chopsticks, plates, dishes, knives, forks, and other tableware to clean them. With the widespread use of dishwashers, those with a visible door design are favored by consumers because they allow for direct observation of the dishwashing process. In addition to visibility, the door also needs to be airtight.

[0003] To meet the need for visibility, dishwashers require glass to be installed on the door. In existing technology, glass inserts are usually molded onto the plastic door backing, but this will generate residual stress, especially at the corners of the glass. The residual stress makes the glass prone to cracking, which will affect the sealing and reliability of the door, and may even affect the safety of the door.

[0004] Accordingly, there is a need in the art for a new door assembly for cleaning equipment and a cleaning equipment to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the glass of the dishwasher door is prone to cracking due to the insert molding process, which affects the sealing and reliability.

[0006] In a first aspect, the present invention provides a door assembly for a cleaning device, the door assembly comprising: a door shell; a door liner, the door liner including a door liner body and a clamping portion connected to each other, the door liner body being connected to the door shell; a mounting frame, the mounting frame and the door liner body abutting against each other by a clamping force, the magnitude of the clamping force being adjustable; and a first viewing panel, the edge of the first viewing panel being clamped between the clamping portion and the mounting frame.

[0007] When the above technical solution is adopted, since the mounting frame and the door liner body abut against each other through clamping force, the clamping part and the mounting frame connected to the door liner body can clamp the first visible panel. Since the clamping force is adjustable, the clamping force of the clamping part and the mounting frame on the first visible panel is also adjustable. This ensures that there is sufficient pressure between the clamping part and the mounting frame and the first visible panel to achieve clamping and fixing, while also increasing the contact area between the clamping part and the mounting frame and the first visible panel. This reduces stress concentration caused by uneven contact, thereby avoiding cracking caused by stress concentration. In addition, it can also prevent excessive clamping force from damaging or even cracking the first visible panel, thus avoiding affecting the sealing and reliability of the door assembly.

[0008] In a specific embodiment of the door assembly for the cleaning equipment described above, adhesive is filled between the first visible panel and the clamping part, and between the first visible panel and the mounting frame.

[0009] By filling the space between the first visible panel and the clamping part and the mounting frame with adhesive, the reliability of the connection is improved. At the same time, it can also avoid the deformation or stress concentration that could cause cracking of the first visible panel when clamping it due to uneven contact surfaces between the first visible panel and the clamping part and the mounting frame. In addition, after the adhesive solidifies, it can increase the contact area between the clamping part and the mounting frame and the first visible panel, so that the clamping force of the clamping part and the mounting frame on the first visible panel is evenly distributed on the edge of the first visible panel through the adhesive. This further avoids stress concentration and cracking caused by uneven local force on the edge of the first visible panel.

[0010] In a specific embodiment of the door assembly for the cleaning equipment described above, the clamping part is provided with a first adhesive groove, which is used to fill the adhesive liquid.

[0011] By filling the first adhesive tank with adhesive and connecting the first visible panel to the clamping part, the amount of adhesive filling can be increased, ensuring the connection strength and increasing the ability to absorb deformation. This further prevents the first visible panel from cracking due to stress concentration caused by uneven local stress.

[0012] In a specific embodiment of the door assembly for the cleaning equipment described above, the mounting frame is provided with a second adhesive groove, which is used to fill the adhesive liquid.

[0013] By using the above technical solution, the first visible panel can be connected to the mounting frame by filling the second glue tank with glue, which increases the amount of glue filling, ensuring the connection strength and increasing the ability to absorb deformation.

[0014] In a specific embodiment of the door assembly for the cleaning equipment described above, the clamping part is provided with a window, the first visible panel covers the window, the clamping part is provided with an overflow groove, the overflow groove is located between the first glue groove and the window and communicates with the first glue groove.

[0015] When the above technical solution is adopted, an overflow groove is set between the first glue tank and the window, so that the glue in the first glue tank can enter the overflow groove after overflowing, instead of overflowing directly into the window position of the clamping part. The clamping part is exposed outside when the door assembly is opened. Therefore, setting the overflow groove on the clamping part can effectively prevent glue from overflowing and affecting the appearance.

[0016] In the specific embodiment of the door assembly for the cleaning equipment described above, the door liner further includes a first connecting part connected to the door liner body, and the mounting frame is provided with a second connecting part, the second connecting part being connected to the first connecting part by bolts.

[0017] When the above technical solution is adopted, since the second connecting part and the first connecting part are connected by bolts, the preload of the bolts can be adjusted by adjusting the tightening torque of the bolts, and thus the clamping force between the second connecting part and the first connecting part connected by bolts can be adjusted. This allows for the adjustment of the clamping force between the clamping part and the mounting frame, thereby achieving the clamping and fixing of the first visible panel while reducing stress concentration caused by uneven contact. This avoids cracking caused by stress concentration and prevents damage to the first visible panel caused by clamping force.

[0018] In the specific embodiment of the door assembly for the cleaning equipment described above, the tightening torque of the bolt is 0.5 to 2 N·m.

[0019] When the above technical solution is adopted, the tightening torque of the bolt is controlled within the range of 0.5 to 2 N·m. This can not only clamp and fix the first visible panel, but also reduce stress concentration caused by uneven contact, thereby avoiding cracking caused by stress concentration and avoiding damage to the first visible panel caused by excessive clamping force.

[0020] In the specific embodiment of the door assembly for the cleaning equipment described above, the first connecting part is located on one side of the cleaning chamber of the cleaning equipment, the second connecting part is provided with a light hole, the first connecting part is provided with a threaded hole, and the bolt passes through the light hole and is threadedly connected to the threaded hole.

[0021] When the above technical solution is adopted, since the bolt passes through the light hole from the second connection part and is screwed into the threaded hole of the first connection part, the head of the bolt is on the mounting frame side, which avoids the bolt head being exposed on the cleaning chamber side, thereby avoiding the bolt being easily corroded and deformed by the humid and hot environment in the cleaning chamber, and improving the reliability of the connection between the first connection part and the second connection part.

[0022] In a specific embodiment of the door assembly for the cleaning equipment described above, the door shell is provided with a top block, and the mounting frame is disposed between the top block and the clamping part. The mounting frame can abut against the top block to restrict the mounting frame from moving in the opposite direction to the cleaning chamber of the cleaning equipment; and / or the door assembly further includes a second viewing panel, the door liner body and the second viewing panel are respectively connected to both sides of the door shell, and the door liner body is located on one side of the cleaning chamber of the cleaning equipment.

[0023] When the above technical solution is adopted, since the door liner body usually contacts the cleaning equipment body to achieve a seal between the door assembly and the cleaning equipment body, a large deformation of the door liner body will affect the sealing effect. However, since the mounting frame can abut against the top block to limit the movement of the support frame in the opposite direction of the cleaning chamber, and the mounting frame is connected to the door liner body, when the door liner body is subjected to external force, the mounting frame can limit the deformation of the door liner body to a set small range, thereby avoiding a large deformation of the door liner body that would cause the seal between it and the cleaning equipment body to fail, further ensuring the sealing performance of the door assembly. The setting of two visible panels can further improve the sealing effect and also improve the heat insulation effect, reduce heat loss in the cleaning chamber, and improve the cleaning and drying efficiency of tableware.

[0024] In a second aspect, the present invention also provides a cleaning device, the cleaning device including a door assembly for cleaning the device.

[0025] When the above technical solution is adopted, the cleaning equipment for the door liner assembly can prevent the first visible panel from cracking due to residual stress, which would affect the sealing and reliability of the door assembly.

[0026] Compared with the prior art, the beneficial effects of the door assembly for cleaning equipment provided by the present invention are as follows: Since the mounting frame and the door liner body abut against each other through clamping force, the clamping part and the mounting frame connected to the door liner body can clamp the first visible panel. Since the magnitude of the clamping force is adjustable, the clamping force of the clamping part and the mounting frame on the first visible panel is also adjustable. This ensures that there is sufficient pressure between the clamping part and the mounting frame and the first visible panel to achieve clamping and fixing, while also increasing the contact area between the clamping part and the mounting frame and the first visible panel, reducing stress concentration caused by uneven contact, and thus avoiding cracking caused by stress concentration. In addition, it can also prevent excessive clamping force from damaging or even cracking the first visible panel, thereby avoiding affecting the sealing and reliability of the door assembly.

Detailed Implementation

[0034] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

These are used merely for ease of description and do not indicate or imply that the relevant devices or elements must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0036] Furthermore, it should be noted that in the description of this invention, ordinal numbers such as "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Moreover, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can also refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0037] As indicated in the background art, in existing technologies, the glass of dishwasher doors is prone to cracking due to the insert molding process, affecting sealing and reliability. The aim is to address this issue by having a mounting frame abut against the door liner body, allowing the clamping part connected to the door liner body and the mounting frame to clamp the first visible panel. Since the clamping force between the mounting frame and the door liner body is adjustable, the clamping force of the clamping part and the mounting frame on the first visible panel is also adjustable. This ensures sufficient pressure between the clamping part and the mounting frame and the first visible panel for clamping and fixing, while also increasing the contact area between the clamping part and the mounting frame and the first visible panel, reducing stress concentration caused by uneven contact, and thus preventing cracking due to stress concentration. Furthermore, it avoids damage or even cracking of the first visible panel caused by excessive clamping force, thereby preventing any impact on the sealing and reliability of the door assembly.

[0038] First refer to Figure 1 , Figure 1 The overall structure of the cleaning device of the present invention is shown. For example... Figure 1 As shown, the cleaning device of the present invention includes a cleaning device body 1 and a door assembly 2. A cleaning chamber 11 is formed within the cleaning device body 1. The door assembly 2 is used to open and close the opening of the cleaning chamber 11. The door assembly 2 can be hinged to the cleaning device body 1 or slidably connected to it. The cleaning device may further include a spraying device for spraying washing water into the cleaning chamber 11, and a heating device for heating the washing water or the cleaning chamber 11 to perform hot water washing and drying treatment on the tableware in the cleaning chamber 11. The spraying device may be a spray arm.

[0039] It should be noted that the present invention does not impose any restrictions on the specific structure of the cleaning equipment body 1, the spraying device, and the heating device.

[0040] It should also be noted that the cleaning equipment can be a dishwasher, an ultrasonic cleaner, or other cleaning equipment, without any specific limitations.

[0041] Then refer to Figures 1-4 , Figure 2 This is a schematic diagram of the overall structure of the door assembly of the present invention. Figure 3 yes Figure 2 AA section view, Figure 4 yes Figure 3 A partially enlarged structural diagram of part B. (See diagram below.) Figures 1-4As shown, the door assembly 2 of the present invention includes a door shell 21, a door liner 22, a mounting frame 23, and a first visible panel 24. The door liner 22 includes a door liner body 221 and a clamping part 222 connected to each other. The door liner body 221 is connected to the door shell 21. The mounting frame 23 and the door liner body 221 abut against each other by a clamping force, and the magnitude of the clamping force is adjustable. The edge of the first visible panel 24 is clamped between the clamping part 222 and the mounting frame 23. Because the mounting frame 23 and the door liner body 221 abut against each other through clamping force, the clamping part 222 and the mounting frame 23 connected to the door liner body 221 can clamp the first visible panel 24. Since the clamping force is adjustable, the clamping force of the clamping part 222 and the mounting frame 23 on the first visible panel 24 is also adjustable. This ensures that there is sufficient pressure between the clamping part 222 and the mounting frame 23 and the first visible panel 24 to achieve clamping and fixing. At the same time, it can also increase the contact area between the clamping part 222 and the mounting frame 23 and the first visible panel 24, reduce stress concentration caused by uneven contact, and thus avoid cracking caused by stress concentration. In addition, it can also prevent excessive clamping force from damaging or even cracking the first visible panel 24, thereby avoiding affecting the sealing and reliability of the door assembly 2.

[0042] It should be noted that the first visible panel 24 can be a glass plate, an acrylic plate, or a polycarbonate plate, as long as it is transparent and heat-resistant. In addition, the door liner 22 can be made of plastic material. The door liner body 221 and the clamping part 222 can be integrally molded or they can be separate structures fixedly connected into a whole.

[0043] As one possible implementation method, such as Figure 4 As shown, adhesive is used to fill the space between the first visible panel 24 and the clamping part 222, as well as between the first visible panel 24 and the mounting frame 23. Filling the space between the first visible panel 24 and the clamping part 222 and the mounting frame 23 with adhesive improves the reliability of the connection and prevents deformation or stress concentration that could lead to cracking of the first visible panel 24 when clamped due to uneven contact surfaces. Furthermore, after the adhesive solidifies, it increases the contact area between the clamping part 222 and the mounting frame 23 and the first visible panel 24, allowing the clamping force of the clamping part 222 and the mounting frame 23 to be evenly distributed along the edge of the first visible panel 24 through the adhesive. This further prevents stress concentration and cracking caused by uneven local stress at the edge of the first visible panel 24.

[0044] Optionally, the clamping part 222 is provided with a first adhesive groove 2221 for filling with adhesive; the mounting frame 23 is provided with a second adhesive groove 231 for filling with adhesive. By filling the first adhesive groove 2221 and the second adhesive groove 231 with adhesive, the first visible panel 24 is connected to the clamping part 222 and the mounting frame 23. This increases the amount of adhesive filling, ensuring connection strength while also increasing the ability to absorb deformation, further preventing the first visible panel 24 from cracking due to stress concentration caused by uneven local stress. It should be noted that the first adhesive groove 2221 and the second adhesive groove 231 can be annular grooves arranged around the edge of the first visible panel 24, or the first adhesive groove 2221 and the second adhesive groove 231 can be multi-segment grooves evenly arranged around the edge of the first visible panel 24.

[0045] Optionally, the clamping part 222 is provided with a window 2222, which can be circular or elliptical in shape. The first visible panel 24 covers the window 2222. The clamping part 222 is provided with an overflow groove 2223, which is located between the first glue groove 2221 and the window 2222 and communicates with the first glue groove 2221. The overflow groove 2223 is provided between the first glue groove 2221 and the window 2222 so that the glue overflowing from the first glue groove 2221 can enter the overflow groove 2223 instead of overflowing directly into the window 2222 of the clamping part 222. The clamping part 222 is exposed when the door assembly 2 is opened. Therefore, the overflow groove 2223 provided on the clamping part 222 can effectively prevent glue overflow.

[0046] As one possible implementation method, such as Figure 1 and Figure 4 As shown, the door liner 22 also includes a first connecting portion 223 connected to the door liner body 221, and a second connecting portion 25 is provided on the mounting frame 23. The second connecting portion 25 and the first connecting portion 223 are connected by bolts. Since the second connecting portion 25 and the first connecting portion 223 are connected by bolts, the preload of the bolts can be adjusted by adjusting the tightening torque of the bolts, thereby adjusting the clamping force between the second connecting portion 25 and the first connecting portion 223 connected by bolts. This allows for adjustment of the clamping force between the clamping portion 222 and the mounting frame 23, thereby clamping and fixing the first visible panel 24 while reducing stress concentration caused by uneven contact. This prevents cracking caused by stress concentration and avoids damage to the first visible panel 24 caused by clamping force.

[0047] Furthermore, the second connecting part 25 is provided on the outer periphery of the mounting frame 23. There can be one or more second connecting parts 25. When there are multiple second connecting parts 25, they are evenly arranged on the outer periphery of the mounting frame 23. The first connecting part 223 and the second connecting part 25 are arranged in a one-to-one correspondence to provide a uniform clamping force in the circumference of the first visible panel 24, which further avoids stress concentration on the first visible panel 24 and easy cracking.

[0048] Optionally, the first connecting part 223 is located on one side of the cleaning chamber 11 of the cleaning equipment, the second connecting part 25 is provided with a light hole 251, and the first connecting part 223 is provided with a threaded hole 2231. The bolt passes through the light hole 251 and is threaded into the threaded hole 2231. Since the bolt passes through the light hole 251 from the side of the second connecting part 25 and is screwed into the threaded hole 2231 of the first connecting part 223, the head of the bolt is on the side of the mounting frame 23, which avoids the head of the bolt being exposed on the side of the cleaning chamber 11. This avoids the bolt being easily corroded and deformed by the humid and hot environment in the cleaning chamber 11, and improves the reliability of the connection between the first connecting part 223 and the second connecting part 25.

[0049] Optionally, the tightening torque of the bolt can be between 0.5 and 2 N·m. When the tightening torque of the bolt is greater than or equal to 0.5 N·m, the first visible panel 24 can be clamped and fixed while reducing stress concentration caused by uneven contact, thereby avoiding cracking due to stress concentration. As the tightening torque of the bolt increases, the clamping force between the second connecting part 25 and the first connecting part 223 generated by the preload of the bolt also gradually increases, making the fixing effect of the first visible panel 24 more reliable. However, when the tightening torque of the bolt is greater than 2 N·m, the first visible panel 24 is prone to deformation due to the clamping force, which in turn causes stress concentration and cracking. Therefore, controlling the tightening torque of the bolt within the range of 0.5 to 2 N·m can clamp and fix the first visible panel 24 while reducing stress concentration caused by uneven contact, thereby avoiding cracking due to stress concentration, and also avoiding damage to the first visible panel 24 caused by excessive clamping force.

[0050] It should be noted that the tightening torque of a bolt refers to the torque of the rotational force applied when tightening the bolt, which is used to overcome the friction between the threads and to stretch the bolt to generate a preload. The clamping force between the first connecting part 223 and the second connecting part 25 connected by the bolt is obtained by converting the preload of the bolt.

[0051] As one possible implementation method, such as Figure 1 and Figure 4As shown, a top block 211 is provided on the door shell 21, and a mounting frame 23 is located between the top block 211 and the clamping part 222. The mounting frame 23 can abut against the top block 211 to restrict the mounting frame 23 from moving in the opposite direction to the cleaning chamber 11 of the cleaning equipment. Since the door liner body 221 is usually in contact with the cleaning equipment body 1 to achieve a seal between the door assembly 2 and the cleaning equipment body 1, a large deformation of the door liner body 221 will affect the sealing effect. Since the mounting frame 23 can abut against the top block 211 to restrict the support frame from moving in the opposite direction to the cleaning chamber 11, and the mounting frame 23 is connected to the door liner body 221, when the door liner body 221 is subjected to external force, the mounting frame 23 can limit the deformation of the door liner body 221 to a set small range, thereby avoiding a large deformation of the door liner body 221 and the failure of the seal between it and the cleaning equipment body 1, and further ensuring the sealing performance of the door assembly 2. It should be noted that the mounting frame 23 and the top block 211 can be in contact with each other or have a gap. Those skilled in the art can adjust this according to the allowable deformation of the door liner body 221.

[0052] As one possible implementation method, such as Figure 1 and Figure 4 As shown, the door assembly 2 also includes a second visible panel 26. The door liner body 221 and the second visible panel 26 are respectively connected to the two sides of the door shell 21, and the door liner body 221 is located on one side of the cleaning chamber 11 of the cleaning equipment. By setting two visible panels, the sealing effect can be further improved, the heat insulation effect can be improved, the heat loss in the cleaning chamber 11 can be reduced, and the cleaning and drying efficiency of tableware can be improved.

[0053] Furthermore, a third adhesive groove 212 is provided on one side of the second visible panel 26 of the door shell 21. The third adhesive groove 212 is used to fill adhesive, and the second visible panel 26 is connected to the adhesive groove through the adhesive. By filling the third adhesive groove 212 with adhesive to connect the second visible panel 26 to the door shell 21, the connection strength is ensured while avoiding adhesive overflow that would affect the aesthetics. The third adhesive groove 212 is arranged around the circumference of the second visible panel 26. There can be one or more third adhesive grooves. When there is only one third adhesive groove 212, it is a groove that is connected in a complete circle. When there are multiple third adhesive grooves 212, the multiple third adhesive grooves 212 are evenly distributed around the circumference of the second visible panel 26. As long as the third adhesive groove 212 can be filled with adhesive and the second visible panel 26 is connected to the third adhesive groove 212 of the door shell 21 through the adhesive, those skilled in the art can adjust it as needed.

[0054] It should be noted that the second visible panel 26 can be a glass plate, an acrylic plate, or a polycarbonate plate, as long as it is transparent and heat-resistant.

[0055] Possibly, the second visible panel 26 of the door shell 21 is provided with a panel mounting groove on one side, and a third adhesive groove 212 is provided on the bottom wall of the panel mounting groove. The second visible panel 26 is installed in the panel mounting groove and fixed in the panel mounting groove by filling the third adhesive groove 212 with adhesive.

[0056] It should be noted that the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above embodiments so that the present invention can be applied to more specific application scenarios.

[0057] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
