Description

Technical Field

[0001] The present application relates to the technical field of dishwashers, and in particular to a blocking structure and a dishwasher. Background Art

[0002] A dishwasher is a kitchen appliance that integrates multiple functions such as dishwashing, disinfection, and storage, and is gaining favor with more and more families.

[0003] At present, the water inlet channel behind the water inlet valve of the dishwasher is usually normally open. During the production process of the dishwasher, it is necessary to perform water flow detection. The specific operation is as follows: Figure 6 As shown, the test water enters from the water inlet valve 2, and is then transported to the respirator 3, the water softener 4 and the water cup 5 in sequence through the channel pipe, and finally the test water is discharged from the water inlet hole on the water cup 5.

[0004] Before a dishwasher leaves the factory, it must drain the incoming water during the water flow test. However, during this process, a small amount of residual water may remain in the water inlet channel, particularly in the resin chamber of the water softener 4. This can cause the remaining water to spill into the dishwasher's interior due to bumps and vibrations during transportation, resulting in a poor unpacking experience for users. Utility Model Content

[0005] Based on this, it is necessary to provide a blocking structure and a dishwasher to address the above-mentioned problems of the dishwasher.

[0006] A blocking structure of the present application is applied to a dishwasher.

[0007] The blocking structure includes a blocking column and a plug connected to the blocking column, wherein the diameter of the blocking column is slightly smaller than the water inlet hole on the washing chamber of the dishwasher, and the plug is at least partially wider than the water inlet hole;

[0008] The blocking column is inserted into the water inlet hole, and a sealing member is provided on the blocking column, and the sealing member is used to seal the gap between the blocking column and the water inlet hole;

[0009] It also includes a handle, which is connected to the plug, and the handle is used to drive the blocking column to rotate and / or plug and unplug relative to the water inlet.

[0010] The first aspect of the present application discloses a blocking structure, comprising a blocking column, a plug, and a handle, wherein the diameter of the blocking column is slightly smaller than the diameter of the water inlet hole on the washing chamber of the dishwasher, the blocking column can be inserted into the water inlet hole, and the width of the plug is at least partially larger than the diameter of the water inlet hole, so as to prevent the blocking structure from being sunk into the water inlet hole as a whole; a sealing member is provided on the blocking column, and the sealing member can seal the gap between the blocking column and the water inlet hole, thereby preventing the water remaining in the water softener from leaking into the washing chamber through the water inlet hole; a handle is connected to the other end of the plug, and by holding the handle, the blocking column can be rotated or plugged in relative to the water inlet hole, thereby enabling the blocking structure of the present application to be disassembled and assembled from the water inlet hole of the dishwasher, in a simple and reliable manner. The blocking structure of the present application blocks the water inlet hole of the dishwasher after the dishwasher completes the water flow test and before leaving the factory, thereby preventing the residual water in the dishwasher from spilling into the inner cavity of the dishwasher due to bumps, vibrations, etc. during transportation, resulting in a poor user experience during the unpacking process.

[0011] In one embodiment, the sealing member is an annular elastic sealing ring, and the sealing member is sleeved on the surface of the blocking column.

[0012] The sealing structure in the above embodiment further defines the sealing member as a ring-shaped elastic sealing ring. When the sealing column is inserted into the water inlet hole, the sealing ring on the sealing column rubs against the wall of the water inlet hole, the sealing ring undergoes elastic deformation, and the sealing ring and the water inlet hole are interference fit to achieve sealing between the sealing column and the water inlet hole.

[0013] In one embodiment, the sealing member and the blocking column are formed into an integrated structure by injection molding.

[0014] The sealing structure in the above embodiment further limits the sealing part and the sealing column to be integrally formed by injection molding. Based on the above design, compared with the method of providing an independent sealing ring on the sealing column, the difficulty of assembling the sealing column, the sealing part and the water inlet hole is reduced. In addition, the integral molding of the sealing column and the sealing part can reduce the accessory interface, improve the sealing performance of the product, and save production time and cost.

[0015] In one embodiment, the number of the sealing members is not less than one, and the sealing members are distributed at intervals on the blocking column.

[0016] The sealing structure in the above embodiment further limits the sealing column to be provided with at least one sealing member. For example, the number of sealing members is two, and the two sealing members are spaced apart and distributed on the sealing column, which can realize multi-layer sealing and improve the sealing performance.

[0017] In one embodiment, the handle is a flat block-shaped structure.

[0018] The blocking structure in the above embodiment further limits the handle to a flat structure, which is convenient for the user to hold the blocking structure, so that the blocking column can be rotated relative to the water inlet, thereby allowing the blocking column to be inserted deeper into the water inlet or more easily pulled out of the water inlet, which is ergonomic.

[0019] In one embodiment, a first through hole is formed on the handle, and the first through hole is used for connecting an external pulling structure.

[0020] The blocking structure in the above embodiment further defines a first through-hole on the handle for connecting an external pulling structure. When the blocking column is difficult to remove from the water inlet due to the large friction between the seal on the blocking column and the wall of the water inlet, the blocking column can be pulled on the first through-hole by, for example, a pull rope or a hook, thereby removing the blocking structure from the water inlet. In addition, the user can also insert a finger into the first through-hole to pull the blocking column relative to the water inlet. The above design not only avoids the risk of the blocking structure being unable to be removed, but also reduces the material used in the product, thereby reducing costs.

[0021] In one embodiment, the thickness of the plug gradually decreases along the blocking column toward the handle.

[0022] The sealing structure in the above embodiment further limits the thickness of the plug to gradually decrease along the sealing column toward the handle, that is, the thickness of the plug close to the sealing column is larger, providing a larger contact area for connection with the sealing column, ensuring the connection strength between the sealing column and the plug, and preventing the sealing column from breaking off from the plug and remaining on the water inlet and unable to be pulled out.

[0023] In one embodiment, the blocking column, the plug and the handle are formed into an integrated structure by injection molding.

[0024] The blocking structure in the above embodiment further limits the blocking column, the plug and the handle to be integrally formed by injection molding. Based on the above design, the molding can be completed in one process, eliminating the trouble of multiple processing and assembly, greatly improving the production efficiency, saving production time and processing costs. Moreover, through the one-piece molding method, the processed blocking structure can be guaranteed to have high precision, high strength and beautiful appearance, avoiding errors in processing and mistakes in assembly.

[0025] In one embodiment, the blocking column and the plug are detachably connected.

[0026] The blocking structure in the above embodiment further defines that the blocking column and the plug are mutually detachable, and different sizes of blocking columns can be replaced according to the diameter of the water inlet, thereby adapting to different dishwashers and improving the fault tolerance of the blocking structure of the present application. In particular, the blocking column and the plug can be detachably connected by a threaded connection.

[0027] In one embodiment, the dishwasher provided in the second aspect of the present application includes a blocking structure as described in any one of the above items. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, for the purposes of describing the embodiments of the present application herein.

[0039] like Figures 1 to 5 As shown, this embodiment provides a blocking structure 1 for use in a dishwasher. The blocking structure 1 includes a blocking column 10 and a plug 20 connected to the blocking column 10. The blocking column 10 has a diameter slightly smaller than a water inlet 501 on a washing chamber of the dishwasher, and the plug 20 has a width at least partially larger than the water inlet 501.

[0040] The blocking column 10 is inserted into the water inlet hole 501. A sealing member 110 is provided on the blocking column 10. The sealing member 110 is used to seal the gap between the blocking column 10 and the water inlet hole 501.

[0041] It also includes a handle 30 , which is connected to the plug 20 , and is used to drive the blocking column 10 to rotate and / or plug and unplug relative to the water inlet hole 501 .

[0042] The blocking structure 1 in the above embodiment includes a blocking column 10, a plug 20 and a handle 30, wherein the diameter of the blocking column 10 is slightly smaller than the diameter of the water inlet hole 501 on the washing chamber of the dishwasher, and the blocking column 10 can be inserted into the water inlet hole 501, and the width of the plug 20 is at least partially larger than the diameter of the water inlet hole 501 to prevent the blocking structure 1 from sinking into the water inlet hole 501 as a whole; by arranging a sealing member 110 on the blocking column 10, the sealing member 110 can seal the gap between the blocking column 10 and the water inlet hole 501, thereby preventing the water remaining in the water softener 4 from leaking into the washing chamber through the water inlet hole 501; a handle 30 is connected to the other end of the plug 20, and by holding the handle 30, the blocking column 10 can be rotated or plugged in relative to the water inlet hole 501, thereby enabling the blocking structure 1 of the present application to be disassembled and assembled at the water inlet hole 501 on the dishwasher, in a simple and reliable manner. The sealing structure 1 of the present application seals the water inlet hole 501 on the dishwasher after the dishwasher completes the water flow test and before leaving the factory, so as to prevent the residual water in the dishwasher from spilling into the inner cavity of the dishwasher due to bumps, vibrations, etc. during transportation, resulting in a bad experience for users during the unpacking process.

[0043] like Figure 1 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the sealing member 110 is an annular elastic sealing ring, and the sealing member 110 is sleeved on the surface of the blocking column 10.

[0044] The above embodiment further defines that the sealing member 110 is an annular elastic sealing ring. When the blocking column 10 is inserted into the water inlet hole 501, the sealing ring on the blocking column 10 rubs against the wall of the water inlet hole 501, and the sealing ring undergoes elastic deformation. The sealing ring and the water inlet hole 501 are interference fit to achieve sealing between the blocking column 10 and the water inlet hole 501.

[0045] In addition to the features of the above embodiments, this embodiment further defines that the sealing member 110 and the blocking column 10 are formed into an integrated structure by injection molding.

[0046] The above embodiment further defines that the sealing member 110 and the sealing column 10 are integrally formed by injection molding. Based on the above design, compared with the method in which an independent sealing ring is sleeved on the sealing column 10, the difficulty of assembling the sealing column 10, the sealing member 110 and the water inlet hole 501 is reduced. In addition, the integral molding of the sealing column 10 and the sealing member 110 can reduce the accessory interface, improve the sealing performance of the product, and save production time and cost.

[0047] like Figure 1 and Figure 5 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the number of the sealing members 110 is not less than one, and the sealing members 110 are distributed at intervals on the blocking column 10 .

[0048] The above embodiment further defines that at least one seal 110 is provided on the blocking column 10. For example, the number of seals 110 is two, and the two seals 110 are spaced apart and distributed on the blocking column 10, which can realize multi-layer sealing and improve the sealing performance.

[0049] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the handle 30 is a flat block structure.

[0050] The above embodiment further defines that the handle 30 has a flat structure, which is convenient for the user to hold the blocking structure 1, so that the blocking column 10 rotates relative to the water inlet hole 501, thereby allowing the blocking column 10 to be inserted deeper into the water inlet hole 501 or the blocking column 10 to be pulled out of the water inlet hole 501 more easily, which is ergonomic.

[0051] like Figure 1 As shown, in addition to the features of the above embodiment, this embodiment further defines: a first through hole 301 is opened on the handle 30, and the first through hole 301 is used for externally connecting a pulling structure.

[0052] The above embodiment further defines that the handle 30 is provided with a first through hole 301 for an external pulling structure. When the friction between the sealing member 110 on the blocking column 10 and the wall of the water inlet hole 501 is large, the blocking column 10 is not easy to be pulled out of the water inlet hole 501. At this time, the blocking structure 1 can be pulled on the first through hole 301 by means of a pull rope or a hook, thereby pulling the blocking structure 1 out of the water inlet hole 501. In addition, the user can also insert a finger into the first through hole 301 to pull the blocking column 10 relative to the water inlet hole 501. The above design not only avoids the risk of the blocking structure 1 being unable to be pulled out, but also reduces the material used in the product, thereby reducing costs.

[0053] like Figure 1 As shown, in addition to the features of the above embodiment, this embodiment further defines that the thickness of the plug 20 gradually decreases along the blocking column 10 toward the handle 30 .

[0054] The above embodiment further defines that the thickness of the plug 20 gradually decreases along the blocking column 10 toward the handle 30, that is, the thickness of the plug 20 close to the blocking column 10 is larger, providing a larger contact area for connection with the blocking column 10, thereby ensuring the connection strength between the blocking column 10 and the plug 20, and preventing the blocking column 10 from breaking off from the plug 20 and remaining on the water inlet hole 501 and unable to be pulled out.

[0055] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further defines that the blocking column 10, the plug 20 and the handle 30 are formed into an integrated structure by injection molding.

[0056] The above embodiment further specifies that the blocking column 10, the plug 20, and the handle 30 are integrally formed by injection molding. Based on the above design, the molding can be completed in a single process, eliminating the trouble of multiple processing and assembly, greatly improving production efficiency, saving production time and processing costs. Furthermore, the integrated molding method can ensure that the processed blocking structure 1 has high precision, high strength, and beautiful appearance, avoiding errors in processing and mistakes in assembly. It should be noted that the blocking column 10, the plug 20, and the handle 30 can all be made of plastic materials.

[0057] In addition to the features of the above embodiment, this embodiment further stipulates that the blocking column 10 and the plug 20 are detachably connected.

[0058] The above embodiment further defines that the blocking column 10 and the plug 20 are mutually detachable, and that different sizes of blocking columns 10 can be replaced according to the diameter of the water inlet 501, thereby adapting to different dishwashers and improving the fault tolerance of the blocking structure 1 of the present application. The blocking column 10 and the plug 20 can be detachably connected by a threaded connection.

[0060] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of this utility model patent shall be determined by the appended claims.
