Description

Technical Field

[0001] The present application belongs to the technical field of dishwashers, and in particular relates to a drainage structure and a hanging member of a dishwasher, and a dishwasher having the drainage structure. Background Art

[0002] Dishwashers currently on the market typically consist of an inner tank and a base. A water cup is located between the bottom of the inner tank and the base to collect the washing water from the inner tank. A drain pump is connected to the water cup to drain the water from the cup. In practice, to save installation space, the drain pump is typically placed horizontally, with the pump's impeller's center of rotation essentially parallel to the horizontal plane, and its water inlet connected horizontally to the side of the water cup. When washing is complete, the drain pump activates to drain the water from the water cup. Because the drain pump uses a centrifugal impeller, when the water in the water cup falls below the upper edge of the pump's water inlet, it draws in air and cannot continue to drain the remaining water. In the final stage of drainage, residual water will still remain in the pump casing and cannot be drained. This can cause residual water to accumulate in the water cup, making it prone to bacterial growth and affecting the hygiene of the dishwasher. Summary of the Invention

[0003] The purpose of the embodiments of the present application is to provide a drainage structure, a hanging piece and a dishwasher of a dishwasher, so as to solve the technical problem in the prior art of dishwashers that residual water in water cups is easily left and cannot be removed.

[0004] To achieve the above objectives, the technical solution adopted in this application is:

[0005] In a first aspect, an embodiment of the present application provides a drainage structure for a dishwasher, comprising:

[0006] A water cup, wherein the water cup has a first drain port and a second drain port;

[0007] A respirator having a water inlet, a water outlet, and a curved flow channel communicating with the water inlet and the water outlet, wherein at least a portion of the curved flow channel is higher than the water inlet and the water outlet;

[0008] A first drainage pump is provided at the first drainage port of the water cup and is connected to the water inlet of the respirator through a first drainage pipe; the water outlet of the respirator is connected to a first external drainage pipe;

[0009] a second drainage pump connected to the second drainage port of the water cup through a second drainage pipe; an output end of the second drainage pump is connected to a second external drainage pipe;

[0010] The hanging member is arranged outside the dishwasher, and is used to hang the first outer pipe and the second outer pipe higher so that at least part of the first outer pipe and the second outer pipe are higher than the pipe openings at both ends.

[0011] The drainage structure provided by the present application has the following advantages: Compared with the prior art, the drainage structure of the present application includes two sets of drainage channels. One set is the main drainage channel, which is connected to the first drain port on the side of the water cup through a first drain pipe to a breather, which is then connected to the first external drain pipe to discharge the water outside the dishwasher. The other set is the secondary drainage channel, which is connected to the second drain port at the bottom of the water cup through a second drain pipe by a second drain pump. The second drain pump uses this second drain pipe to discharge the residual water at the bottom of the water cup through the second external drain pipe to the outside of the dishwasher.

[0012] Since the water on the first outer pipe and the second outer pipe has a backflow situation, the water is easy to flow back into the water cup, resulting in residual water in the water cup that cannot be completely removed. Therefore, the drainage structure of the present application also includes a hanging member, which is used to hang the first outer pipe and the second outer pipe to a high place, so that the first outer pipe and the second outer pipe form a U-shaped pipe with low ends and high middle part outside the dishwasher. The height difference is used to prevent the discharged water from flowing back into the water cup, effectively solving the problem of residual water in the water cup of the dishwasher that cannot be completely removed, and then achieving the goal of removing the residual water in the water cup, ensuring the cleanliness and hygiene of the dishwasher.

[0013] In one embodiment, the water cup is further provided with a check valve plate located above the first drain outlet, the check valve plate having a through hole. Thus, when the second drain pump is activated, any water that may flow back from the first drain outlet is quickly returned to the water cup for drainage by the second drain pump, effectively reducing the operating time of the second drain pump and improving the efficiency of draining residual water from the water cup.

[0014] In one embodiment, the drainage structure further includes a three-way joint, two of which are connected to the first and second external pipes, respectively, and the remaining joint of the three-way joint is connected to the outside world. This facilitates the merging of the external drainage pipes, facilitates the centralized arrangement of the external drainage pipes, and improves the adaptability to the installation environment.

[0015] In one embodiment, the first outer tube and the second outer tube are both hoses, so that the first outer tube and the second outer tube can be easily stretched or bent and deformed, so as to be arranged on the hanging member to form a U-shaped pipe.

[0016] In a second aspect, embodiments of the present application further provide a heightening member for use in the drainage structure of the dishwasher. The heightening member comprises a main body and a mounting lug disposed on the main body. The main body is provided with mounting slots for receiving the first and second outer pipes. The heightening member can be secured to a carrier using the mounting lugs by attaching fasteners such as screws, thereby raising the first and second outer pipes to form a U-shaped conduit.

[0017] In one embodiment, the mounting groove is arc-shaped on the body, with the center of the arc of the mounting groove adjacent to the mounting lug. When the height-hanging member is secured to the carrier via the mounting lug, the middle peak of the mounting groove is adjacent to the mounting lug, with both ends of the mounting groove lower than the mounting lug, thereby forming a U-shaped groove structure. This facilitates the natural formation of a U-shaped pipe mounted on the height-hanging member.

[0018] In one embodiment, the main body is further provided with an anti-drop buckle located on the mounting groove, and the anti-drop buckle is distributed on the notch of the mounting groove, thereby preventing the pipe stuck in the mounting groove from falling off easily, thereby improving the fixing effect of the pipe.

[0019] In a third aspect, an embodiment of the present application further provides a dishwasher, comprising an inner tank, a base, and a drainage structure of the dishwasher, wherein the inner tank is arranged on the base, and the base is provided with fixings for installing the first outer row pipe and the second outer row pipe, and the first outer row pipe and the second outer row pipe respectively extend out of the outside of the dishwasher through the fixings for hanging high processing.

[0020] In one embodiment, the fixing member is a double-ended plug mounted on the mounting hole of the base side wall. The fixing member includes two interconnected connectors, which extend oppositely from each other on the inner and outer surfaces of the base side wall and are used to connect to the pipes. Thus, the first or second outer pipe can be composed of two pipe sections, one section located inside the base and connected to one connector; the other section located outside the base and connected to the other connector, thereby securing the pipe to the base.

[0021] In one embodiment, the fixing member is a ring buckle disposed on the mounting hole of the base side wall. The fixing member includes a pair of mutually interlocking fasteners, which are combined to form a ring body for tightening the pipe. Therefore, during installation, the fixing member can be first tightened to the pipe, and then the fixing member and the pipe can be fixed to the base together. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0048] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0049] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0051] In order to solve the problem of residual water in the dishwasher cup, the commonly used solutions in the relevant technology are:

[0052] The first method is to connect the drain pump to the bottom of the water cup to drain as much residual water as possible during the drainage process. However, this structure, by fixing the drain pump to the bottom of the water cup, increases the height and overall space occupied by the water cup. This also increases the overall thickness and volume of the base that houses the water cup, making the dishwasher base taller and hindering the development of lightweight and compact dishwashers.

[0053] The second method is to install a heating device at the bottom of the water cup to evaporate the remaining water. However, the addition of a heating device not only makes the bottom structure of the water cup more complex and increases the mold manufacturing cost, but also requires the installation of corresponding electrical connection structures, which increases energy consumption and poses the risk of water damage.

[0054] The third method involves installing a forced-drain pump on the water cup or drain pump housing to drain water. The forced-drain pump's water path then merges with the original drain pump's water path in the respirator's flow channel and drains out of the unit, using the respirator's U-shaped flow channel to prevent backflow of external drainage. However, this design still allows some water to flow back into the water cup, and the respirator's U-shaped flow channel cannot completely prevent backflow, resulting in residual water in the water cup that cannot be completely removed.

[0055] Here, the embodiments of the present application provide a novel drainage structure, a hanging height member, and a dishwasher using this drainage structure. The external drainage pipe is hung high, and the hanging height point is used to prevent water from flowing back into the drainage pipe, effectively solving the technical problem that residual water in cups in the dishwasher is easily left and cannot be removed. This is now described in detail.

[0056] Please also refer to Figure 1 and Figure 2 In the dishwasher of the embodiment of the present application, the dishwasher includes an inner tank 100, a base 200, and the drainage structure of the present application. The inner tank 100 is arranged on the base 200. The drainage structure includes a water cup 1, a breather 2, a first drainage pump 3, a second drainage pump 4, and a hanging member 5.

[0057] The water cup 1 is arranged between the inner tank 100 and the base 200, and is used to collect the water in the washing chamber of the inner tank 100 and realize the circulation water circuit under the action of the water pump. Figure 2 As shown, the water cup 1 has a first drain port 11 and a second drain port 12. The first drain port 11 is located on a pump housing laterally disposed on the side of the water cup 1. This pump housing is used to mount a first drain pump 3. The first drain pump 3 is installed in the first drain port 11 of the water cup 1 and then connected to the breather 2 via a first drain pipe 31. Thus, the water path from the first drain pump 3 to the water cup 1, through the breather 2, and then out of the dishwasher serves as the main drainage channel of the dishwasher.

[0058] In this embodiment, the second drain port 12 of the water cup 1 is preferably provided at the bottom of the water cup 1 to collect any residual water in the water cup 1. This means that when the level of the water in the water cup 1 is lower than that of the first drain port 11, the first drain pump 3 is unable to properly drain the water from the water cup 1. The remaining water will then collect at the bottom of the water cup 1 and can be drained through the second drain port 12.

[0059] Please also refer to Figure 2 and Figure 3 The second drain pump 4 is connected to the second drain port 12 of the water cup 1 via a second drain pipe 41. The output end of the second drain pump 4 is connected to a second external drain pipe 42. Thus, the water from the second drain pump 4, connected to the second drain port 12 at the bottom of the water cup 1 through the second drain pipe 41, is discharged outside the dishwasher through the second external drain pipe 42 connected to the output end of the water pump 4, forming a secondary drain channel on the dishwasher. This secondary drain channel removes any residual water from the bottom of the water cup 1, allowing it to be discharged outside the dishwasher through the second external drain pipe 42.

[0060] Please also refer to Figure 4 and Figure 5 The respirator 2 is provided with a water inlet 21, a water outlet 22, and a curved channel 23 located inside the respirator 2. The two ends of the curved channel 23 are respectively connected to the water inlet 21 and the water outlet 22. At least a portion of the curved channel 23 is higher than the water inlet 21 and the water outlet 22, so that the curved channel 23 forms a U-shaped pipe with lower ends and a higher middle portion.

[0061] The water inlet end 21 of the breather 2 is connected to the first drain pipe 31 of the main drain channel, and the water outlet end 22 of the breather 2 is connected to the first drain pipe 32, which discharges the water to the outside of the dishwasher.

[0062] Please also refer to Figure 1 and Figure 5The hanging member 5 is disposed outside the dishwasher. It is used to suspend the first and second outer pipes 32, 42 at a high point, such that at least a portion of the first and second outer pipes 32, 42 is higher than their respective ends. This creates a U-shaped pipe with lower ends and a higher center outside the dishwasher. This height difference prevents the drained water from flowing back into the cup 1 inside the dishwasher.

[0063] Compared to the prior art, the drainage structure provided in the embodiment of the present application includes two sets of drainage channels. One set is the primary drainage channel, which is connected to the first drain port 11 on the side of the water cup 1 by a first drain pump 3, connected to the breather 2 via a first drain pipe 31, and then connected to the first external drain pipe 32 to drain out of the dishwasher. The other set is the secondary drainage channel, which is connected to the second drain port 12 at the bottom of the water cup 1 by a second drain pipe 41. The second drain pump 4 uses the second drain pump 4 to drain the residual water at the bottom of the water cup 1 out of the dishwasher through the second external drain pipe 42.

[0064] Since the water on the first outer pipe 32 and the second outer pipe 42 has a backflow situation, the water is easy to flow back into the water cup 1, resulting in residual water in the water cup 1 that cannot be completely removed. Therefore, the drainage structure of the present application also includes a hanging member 5, which is used to hang the first outer pipe 32 and the second outer pipe 42 to a high place, so that the first outer pipe 32 and the second outer pipe 42 both form a U-shaped pipe with low ends and high middle part outside the dishwasher. The height difference is used to prevent the discharged water from flowing back into the water cup 1, effectively solving the problem of the residual water in the water cup 1 of the dishwasher that cannot be completely removed, thereby achieving the goal of removing the residual water in the water cup 1 and ensuring the cleanliness and hygiene of the dishwasher.

[0065] In practical applications, such as Figure 2 As shown, the dishwasher's drainage process typically starts by activating the primary drain channel, using first drain pump 3 for normal drainage. After the primary drain is complete, the secondary drain channel is activated, using second drain pump 4 to remove any remaining water from cup 1. During the secondary drain process, because second drain pipe 41, the interior of cup 1, first drain pump 3, and first drain pipe 31 are all interconnected, when second drain pump 4 drains the remaining water from cup 1, it can easily pump any remaining water in first drain pipe 31 back into cup 1, causing water backflow.

[0066] Here, in one embodiment of the present application, please refer to Figure 3 and Figure 6 The water cup 1 is further provided with a check valve plate 13 located on the first drain outlet 11 , which is used to prevent the water in the first drain pipe 31 from flowing back into the water cup 1 .

[0067] On the basis of the above, a through hole 131 is opened on the check valve plate 13. By utilizing the backflow situation described above, when the second drain pump 4 is started, the water that may flow back from the first drain port 11 will flow back into the water cup 1 as quickly as possible and be drained away by the second drain pump 4, thereby effectively reducing the working time of the second drain pump 4 and improving the drainage efficiency of the residual water in the water cup 1.

[0068] Regarding the pipe treatment of the first outer pipe 32 and the second outer pipe 42 outside the dishwasher, in one embodiment of the present application, please refer to Figure 1 and Figure 5 The drainage structure of the present application further includes a three-way joint 6 disposed on the outside of the dishwasher. The three-way joint 6 has three joints. Two of the three-way joints are connected to the first external pipe 32 and the second external pipe 42, respectively. The remaining joint of the three-way joint 6 is connected to the outside world, which facilitates the merging of the pipe openings of the external drainage liquid, facilitates the centralized arrangement of the external drainage pipe openings, and improves the applicability to the installation environment.

[0069] In this embodiment, the three-way joint 6 has two joints on one side and one joint on the other side. The two joints on the same side are used to connect the first outer pipe 32 and the second outer pipe 42 respectively; the joint on the other side is convenient for users to handle, and pipes can be connected to the joint and extended into the preset drainage channel for unified drainage.

[0070] Preferably, in one embodiment of the present application, the first outer tube 32 and the second outer tube 42 are both hoses, and preferably corrugated tubes can be used to make the first outer tube 32 and the second outer tube 42 easy to stretch or bend and deform, so as to be arranged on the hanging member 5 to form a U-shaped pipe.

[0071] In this embodiment, the first outer tube 32 and the second outer tube 42 are preferably composed of two pipe sections, each with a rigid tube body at both ends and a corrugated tube in the middle. This allows the rigid tube bodies at both ends to be easily mounted on the carrier, while the corrugated tube in the middle facilitates stretching or bending, facilitating installation on the hanging member 5 to form a U-shaped pipe.

[0072] Regarding the structure of the hanging member 5 in the drainage structure of this application, in one embodiment of this application, please refer to Figure 7 and Figure 8 The height-hanging member 5 includes a body 51 and a mounting lug 52 disposed on the body 51. The body 51 is provided with a mounting groove 53 for inserting the first and second outer tubes 32 and 42. The mounting lug 52 is preferably provided with a fixing hole 521, so that a fastener such as a screw can be inserted through the fixing hole 521 to secure the height-hanging member 5 to a carrier, such as the inner wall of a cabinet tank for mounting a dishwasher.

[0073] In this embodiment, the main body 51 of the hanging member 5 can preferably be a shell structure that matches the shape of the pipeline and is used to semi-enclose or fully surround the pipeline, and the main body 51 has at least two installation grooves 53, so that at least part of the pipe section on the pipeline, such as the first outer row pipe 32 or the second outer row pipe 42 mentioned above, can be respectively embedded in the installation groove 53 and fixed.

[0074] Please also refer to Figure 7 and Figure 8 The mounting groove 53 is arranged in an arc shape on the body 51, that is, the mounting groove 53 on the body 51 is constructed as an arc groove arranged on the body 51, wherein the arc center of the mounting groove 53 is close to the hanging ear 52. It can be understood here that the hanging ear 52 is located in the middle of the arc-shaped mounting groove 53.

[0075] Thus, when the height-hanging member 5 is secured to the carrier via the lugs 52, the central peak of the mounting groove 53 is close to the lugs 52, while both ends of the mounting groove 53 are lower than the lugs 52, thereby forming a U-shaped groove structure. This facilitates raising at least a portion of the first outer tube 32 and / or the second outer tube 42, naturally forming a U-shaped pipe structure.

[0076] Regarding the structure on the hanging member 5, in one embodiment of the present application, please refer to Figure 7 and Figure 8 The main body 51 of the hanging member 5 is also provided with an anti-drop buckle 54 located on the mounting groove 53. The anti-drop buckle 54 is distributed on the notch of the mounting groove 53, thereby preventing the pipe stuck in the mounting groove 53 from falling off easily, thereby improving the fixing effect of the pipe.

[0077] In this embodiment, the anti-drop buckle 54 can preferably be a buckle block on the notch of the installation groove 53. These buckle blocks are arranged on both sides of the notch of the installation groove 53 and are arranged on both sides of the notch of the installation groove 53 in relative positions or staggered positions, so that the pipe is difficult to fall off after being stuck in the installation groove 53.

[0078] Preferably, in one embodiment of the present application, Figure 7 and Figure 8 As shown, operating holes 55 are also provided on the main body 51 of the hanging member 5. These operating holes 55 are connected to the installation groove 53. The operating holes 55 are used for people to insert their fingers to push the pipe out of the installation groove 53, thereby facilitating the removal of the pipe from the hanging member 5 and effectively improving the convenience of the pipe removal operation.

[0079] Regarding the fixing structure of the first outer pipe 32 and the second outer pipe 42 on the dishwasher, in one embodiment of the present application, please refer to Figure 9 and Figure 10A fixing member 7 for mounting the first outer pipe 32 and the second outer pipe 42 is provided on the base 200 of the dishwasher. The first outer pipe 32 and the second outer pipe 42 extend out of the dishwasher through the fixing member 7 respectively.

[0080] Specifically, if Figure 11 As shown, the side wall of the base 200 is provided with mounting holes 201 for the pipes to extend out, and each mounting hole 201 is provided with a fixing member 7. In this embodiment, as shown in FIG. Figure 12 As shown, there are two fixing members 7, which are adjacently arranged on two mounting holes 201 on the side wall of the base 200. The two fixing members 7 are respectively used to set the above-mentioned first outer tube 32 and second outer tube 42, so that the first outer tube 32 and second outer tube 42 can extend out from the side wall of the base 200, making it convenient to hang them together.

[0081] For the specific structure of the fixing member 7, please refer to Figure 11 and Figure 12 The fixing member 7 can preferably be a double-headed plug arranged on the mounting hole 201 on the side wall of the base 200. The fixing member 7 includes two connecting heads 71 ​​arranged on the inner surface and outer surface of the side wall of the base 200. The two connecting heads 71 ​​are connected to each other and extend back to back on the inner and outer surfaces of the side wall of the base 200, respectively, for connecting pipes respectively.

[0082] Preferably, the two connecting heads 71 ​​of the fixing member 7 are integrally formed on the side wall of the base 200 to ensure structural strength.

[0083] Each connector 71 is further provided with a reinforcing rib 72 . The plurality of reinforcing ribs 72 are distributed in a ring shape around the outer periphery of the connector 71 and are integrally connected to the side wall of the base 200 , thereby improving the structural strength of the connector 71 .

[0084] In this way, the first outer tube 32 or the second outer tube 42 can be composed of two pipe sections, one pipe section is located inside the base 200 and connected to a connector 71; the other pipe section is located outside the base 200 and connected to another connector 71, thereby fixed on the base 200.

[0085] For the specific structure of the fixing member 7, please refer to another embodiment of the present application. Figure 12 、 Figure 13 and Figure 14 The fixing member 7 can preferably be an annular buckle set on the mounting hole 201 of the side wall of the base 200. The fixing member 7 includes a pair of buckling members 73 that are buckled with each other. The pair of buckling members 73 are combined with each other to form a ring body for tightening the pipe.

[0086] The splicing surfaces of the pair of semicircular rings are provided with a hook 74 and a fastening portion 75 for fastening to each other, so that the pair of semicircular rings can be fastened to each other to form an annular buckle that can tighten the pipe.

[0087] Therefore, during installation, the fixing member 7 can be first clamped on the pipe, and then the fixing member 7 together with the pipe can be fixed to the base 200, so that the first outer pipe 32 or the second outer pipe 42 is set on the side wall of the base 200 and extends to the outside of the dishwasher.

[0088] Regarding the mounting structure of the fixing member 7 of the ring buckle and the base 200, in one embodiment of the present application, as shown in FIG. Figure 11 、 Figure 14 and Figure 15 As shown, the pair of fasteners 73 are semicircular rings arranged in half, each semicircular ring has a connecting ear 76, and the connecting ear 76 is provided with a protrusion 761, which is used to be fastened with the buckle hole 202 on the base 200.

[0089] The fastener 73 is further provided with a relief block 77 for aligning with the relief hole 203 in the mounting hole 201 of the base 200. When the ring buckle is mounted on the mounting hole 201 of the base 200, the relief block 77 can be first inserted into the relief hole 203. The ring buckle is then rotated to offset the relief block 77 from the relief hole 203, thereby allowing the protrusion 761 on the connecting ear 76 to be securely fastened to the buckle hole 202 on the base 200.

[0090] It can be seen that the above-mentioned installation structure does not need to use fasteners such as screws for threading and fixing, and the ring buckle can be fixed to the base 200 by hand, which effectively improves the installation efficiency.

[0091] It should be noted that, of the two aforementioned fixing member 7 structures, the double-ended plug fixing member 7 structure is more suitable for inserting and fixing pipes with smaller inner diameters. The ring buckle fixing member 7 structure is more suitable for clamping and fixing pipes with larger inner diameters. The choice of fixing member 7 for application can be made based on the specific conditions of the pipe.

[0092] In this embodiment, the first outer pipe 32 serves as the main drainage channel, and thus a pipe with a larger inner diameter is selected for the first outer pipe 32, and preferably a ring-shaped fastener 7 is used for fastening. The second outer pipe 42 serves as the auxiliary drainage channel, and thus the discharge volume of the second outer pipe 42 is relatively small, and a pipe with a smaller inner diameter can be selected, and preferably a double-ended fastener 7 is used for fastening.

[0093] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
