Description

Technical Field

[0001] The utility model belongs to the technical field related to dishwasher exhaust, and in particular relates to a connecting joint, an exhaust pipe component and an integrated dishwasher. Background Art

[0002] An integrated dishwasher is a type of dishwasher that integrates multiple functions such as a dishwasher, fruit and vegetable / seafood washing machine, sink, and cupboard. It is also an integrated kitchen appliance that can be used in many kitchen usage scenarios.

[0003] When the integrated dishwasher is working, a breather is generally used to exhaust air to the overflow seat of the sink. Specifically, an exhaust pipe assembly is used to connect and communicate the breather with the overflow seat. Limited by the installation environment, in order to meet the exhaust volume requirements, the exhaust pipe assembly needs to be flat on the breather for exhaust. Correspondingly, the exhaust pipe assembly uses a 90° angled connection joint to connect and communicate with the breather joint and the bellows. Since the cross-section at the corner of the connection joint is greatly reduced, it is easy for the breather to produce condensed water at the corner of the connection joint during the exhaust process. However, because the connection joint is directly connected to the breather, the exhaust flow in the connection joint is certain, and the smaller the cross-section, the faster the wind speed. This will cause the condensed water at the corner of the connection joint to fail to flow back to the breather smoothly, and produce a bubble blowing sound, which will cause the integrated dishwasher to have abnormal noise during the exhaust process. Utility Model Content

[0004] In view of this, it is necessary to provide a connection joint, an exhaust pipe assembly and an integrated dishwasher for solving the above-mentioned technical problems.

[0005] A connection joint is used in an exhaust pipe assembly; the connection joint comprises:

[0006] A first connector portion, used for connecting and communicating with a flat connector on a respirator;

[0007] A second joint portion, used for connecting and communicating with the bellows in the exhaust pipe assembly, the second joint portion is connected and communicated with the first joint portion, and the aperture of the second joint portion is smaller than the aperture of the first joint portion;

[0008] The portion of the second joint portion used for connecting and communicating with the corrugated pipe is set as a connecting section, and an angle P is formed between the center line of the connecting section and the center line of the first joint portion, wherein 150°≥P≥110°.

[0009] It can be understood that, through the above-mentioned structural arrangement, when the connecting joint is in the process of directing the water vapor discharged from the respirator to the bellows, the condensed water generated in the connecting joint can flow into the respirator along the inner wall of the connecting joint. This can avoid the retention of condensed water at the bend where the first joint part and the second joint part are connected, thereby avoiding the generation of bubble blowing sound and having a noise reduction effect.

[0010] In one embodiment, P=120°.

[0011] In one embodiment, the second joint portion further has a transition section, and the second joint portion is connected and communicated with the first joint portion through the transition section;

[0012] The transition section is in an arc shape, and the aperture of the transition section is equal to the aperture of the connecting section.

[0013] It can be understood that, through the above-mentioned structural arrangement, the second joint portion is connected and communicated with the first joint portion in a circular arc transition manner, so that condensed water can flow in the inner wall of the connecting joint.

[0014] In one embodiment, the first joint portion is in a circular ring shape, and is used to fit over the flat joint. Furthermore, the first joint portion can be connected to the flat joint in an interference fit manner.

[0015] It can be understood that, through the above-mentioned structural setting, the connecting joint can be demolded by hard core pulling, so that the connecting joint does not need to use inserts during preparation. This not only reduces the production cost of the connecting joint, but also further promotes the flow of condensed water in the inner wall of the connecting joint.

[0016] In one embodiment, the second joint portion can abut against the flat joint inserted into the first joint portion to limit the assembly position between the flat joint and the first joint portion.

[0017] It can be understood that the abutment between the second joint part and the flat joint is used to limit the insertion depth of the first joint part when it is inserted into the flat joint, which can facilitate the subsequent assembly between the first joint part and the flat joint.

[0018] In one embodiment, the first joint portion and the second joint portion are integrally injection-molded from a flexible material.

[0019] It can be understood that since the connection joint is made of a flexible material by integral injection molding, this can facilitate the production and preparation of the connection joint.

[0020] The present application also provides an exhaust pipe assembly, comprising a bellows and the above-mentioned connecting joint, wherein the bellows is connected and communicated with the second joint portion.

[0021] In one embodiment, the exhaust pipe assembly further comprises an external joint, which is disposed on an end of the bellows away from the connecting joint and is connected and communicated with the bellows;

[0022] Wherein, the external joint is used to connect and communicate with the overflow seat of the water tank.

[0023] In one embodiment, the external joint includes a first part and a second part, the first part is sleeved on the bellows and connected to the bellows, and the water vapor in the bellows can be discharged to the overflow seat through the second part;

[0024] A guide surface is provided on the inner peripheral wall of the second part facing one end of the first part, and the guide surface encloses a guide cavity whose diameter gradually increases from the direction away from the first part.

[0025] It can be understood that by utilizing the flow guidance of the guide surface, it is possible to avoid condensed water being retained in the inner peripheral wall of the external joint, thereby avoiding the sound of bubbles being blown in the external joint, which has a further noise reduction effect.

[0026] The present application also provides an integrated dishwasher, comprising a breather and the exhaust pipe assembly described above, wherein the connecting joint is connected to and communicated with the flat joint on the breather.

[0027] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0028] The connecting joint, exhaust pipe assembly and integrated dishwasher sought to be protected in the present application can, on the one hand, facilitate the production and preparation of the connecting joint, thereby reducing costs; and on the other hand, can prevent condensed water from being retained in the connecting joint and the external joint, thereby preventing the production of blowing bubbles and reducing noise.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] It should be noted that when an element is referred to as being "provided on" another element, it may be directly provided on the other element or there may be a central element. When an element is considered to be "provided on" another element, it may be directly provided on the other element or there may be a central element at the same time. When an element is considered to be "fixed to" another element, it may be directly fixed to the other element or there may be a central element at the same time.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] like Figure 1 , Figure 2As shown, the connection joint 10 provided in one embodiment of the present application includes a first joint portion 11 and a second joint portion 12. The first joint portion 11 is used to connect and communicate with the flat joint on the respirator (not shown); the second joint portion 12 is used to connect and communicate with the bellows 20 in the exhaust pipe assembly 100. The second joint portion 12 is connected and communicated with the first joint portion 11, and the aperture of the second joint portion 12 is smaller than the aperture of the first joint portion 11; the portion of the second joint portion 12 used to connect and communicate with the bellows 20 is set as a connection section 121, and an angle P is formed between the center line of the connection section 121 and the center line of the first joint portion 11, wherein 150°≥P≥110°. In other words, based on the original structure, the connection joint 10 increases the turning angle of the connection joint 10 at the bend to between 110° and 150°, and also avoids the need to set an insert in the connection joint 10. In this way, when the connecting joint 10 is in the process of conducting the water vapor exhausted from the respirator to the bellows 20, the condensed water generated in the connecting joint 10 can flow into the interior of the respirator along the inner wall 101 of the connecting joint 10, thereby avoiding the retention of condensed water at the bend where the first joint part 11 and the second joint part 12 are connected, thereby avoiding the generation of bubbling sound and having a noise reduction effect.

[0039] It should be noted that the value of the angle P can be 110°, 115°, 120°, 130°, 140°, 150°, etc. Of course, within the value range of the angle P, the value of the angle P is not limited thereto, and it can be set according to actual needs. Here, it is preferred to set the value of P to 120°, and the connection joint 10 is limited by the influence of installation restrictions, so that the angle P of the connection joint 10 cannot be infinitely increased.

[0040] like Figure 1 , Figure 2 As shown, the first joint part 11 is in a circular ring shape, and the first joint part 11 is used to fit the flat joint, and the first joint part 11 can be connected to the flat joint in an interference fit manner. That is to say, the diameter of the first joint part 11 and the second joint part 12 of the connecting joint 10 is changed from circular to circular, and the hole diameter is changed from small to large, so that the connecting joint 10 can be molded by hard core pulling, so that the connecting joint 10 does not need to use an insert when preparing, which can not only reduce the production cost of the connecting joint 10, but also further promote the flow of condensed water in the inner wall 101 of the connecting joint 10.

[0041] It should be noted that, since the first joint portion 11 is connected to the flat joint in an interference fit manner, the sealing between the first joint portion 11 and the flat joint can be ensured to avoid water leakage.

[0042] In the present application, the first joint part 11 and the second joint part 12 are integrally injection molded by a flexible material. That is, the connection joint 10 can be integrally injection molded by a flexible material, which can facilitate the production and preparation of the connection joint 10. Here, the flexible material is configured as rubber, silicone, etc.

[0043] In the present application, since the aperture of the second joint part 12 is smaller than the aperture of the first joint part 11, when the connecting joint 10 is mounted on the flat joint of the respirator through the first joint part 11, the second joint part 12 can abut against the flat joint inserted into the first joint part 11 to limit the assembly position between the flat joint and the first joint part 11, which can facilitate the subsequent assembly between the first joint part 11 and the flat joint.

[0044] like Figure 1 , Figure 2 As shown, the second joint portion 12 further has a transition section 122, and the second joint portion 12 is connected and communicated with the first joint portion 11 through the transition section 122; wherein the transition section 122 is arc-shaped, and the aperture of the transition section 122 is equal to the aperture of the connection section 121. In other words, the second joint portion 12 is connected and communicated with the first joint portion 11 in an arc transition manner, so that condensed water flows in the inner wall 101 of the connection joint 10.

[0045] like Figure 3 As shown, an exhaust pipe assembly 100 provided in an embodiment of the present application includes a bellows 20 and the above-mentioned connecting joint 10 , and the bellows 20 is connected and communicated with the second joint portion 12 of the connecting joint 10 .

[0046] like Figure 3 As shown, the exhaust pipe assembly 100 of the present application also includes an external joint 30, which is arranged on an end of the bellows 20 away from the connecting joint 10 and is connected and communicated with the bellows 20; wherein the external joint 30 is used to connect and communicate with the overflow seat of the water tank (not shown).

[0047] like Figure 4As shown, the external joint 30 includes a first part 31 and a second part 32, the first part 31 is mounted on the bellows 20 and connected to the bellows 20, and the water vapor in the bellows 20 can be discharged to the overflow seat through the second part 32; wherein, a guide surface 3211 is provided on the inner peripheral wall 321 of the second part 32 facing one end of the first part 31, and the guide surface 3211 encloses a guide cavity 301, the diameter of which gradually increases from the direction away from the first part 31. In other words, the water vapor discharged from the bellows 20 to the external joint 30 can be guided by the guide surface 3211, and the condensed water can be avoided from being retained in the inner peripheral wall 321 of the external joint 30, so that the condensed water can pass through the bellows 20 and the connecting joint 10 in sequence, and finally flow back into the respirator, so that the sound of blowing bubbles can be avoided in the external joint 30, which has the effect of further reducing noise. Here, the guide surface 3211 is configured as a conical surface.

[0048] In addition, the present application also provides an integrated dishwasher, including a breather and the exhaust pipe assembly 100 described above, wherein the connecting joint 10 is connected and communicated with the flat joint on the breather.

[0049] The technical features of the above embodiments may be arbitrarily combined. 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.

[0050] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection required by the present invention.
