Description

Technical field

[0001] The utility model relates to a connection structure of a spray arm of a dishwasher. [Background Technology]

[0002] A dishwasher is a household appliance that combines automatic washing and drying functions. It can handle the vast majority of tableware, cups, and utensils on the market and is highly popular for its high degree of automation and excellent cleaning performance. Currently, dishwashers on the market have sliding baskets to facilitate easy access to tableware. Therefore, spray arms cannot be installed on the baskets to prevent interference during sliding. To address this issue, some have proposed designing a sliding structure between the spray arm and the basket. However, this approach is complex and can easily cause the basket to jam when pulled.

[0003] Therefore, it is necessary to make further improvements. [Utility Model Content]

[0004] The purpose of the present invention is to overcome the above problems. We provide a connection structure for the spray arm of a dishwasher, which can perfectly solve the problem of interference between the bowl basket and the spray arm structure.

[0005] To achieve the above-mentioned purpose, the utility model provides a connection structure for a dishwasher spray arm, which includes an inner tank, a bowl basket, a spray arm and a water supply pipe. The bowl basket can slide relative to the inner tank. The spray arm is installed on the bowl basket and has a connecting port. The water supply pipe is arranged on the outside of the inner tank. The inner tank has a mounting port. The water outlet of the water supply pipe extends into the interior of the inner tank through the mounting port. An adapter is provided on the inner side of the inner tank and is fixedly connected to the water outlet. The adapter is connected to the connecting port of the spray arm to supply water.

[0006] In one or more embodiments, a sealing sleeve is connected to the connection port of the spray arm, and the sealing sleeve is provided with an elastic interface. The adapter is connected to the elastic interface, and the elastic interface is tightly attached to the outer peripheral wall of the adapter when connected.

[0007] In one or more embodiments, the sealing sleeve is sleeved on the connecting port, an annular boss is provided on the edge of the connecting port, and the sealing sleeve has an annular connecting groove that cooperates with the annular boss.

[0008] In one or more embodiments, the water outlet has an external thread structure, and the adapter has an internal thread connection port that cooperates with the external thread structure.

[0009] In one or more embodiments, a sealing ring is provided on the outer side of the installation port, the sealing ring is sleeved on the water outlet, and the sealing ring is pressed tightly when the adapter is connected to the water outlet.

[0010] In one or more embodiments, the water inlet of the water supply pipe is connected to the water diversion valve through a water delivery pipe, and a plurality of anti-slip ribs are distributed on the edge of the water inlet.

[0011] In one or more embodiments, a plurality of elastic clips are distributed on the spray arm, and the elastic clips are used to connect with the bowl basket.

[0012] Compared with the background technology, the present invention has the following effects: the spray arm is installed on the bowl basket, and a connecting joint is provided on the inner tank to quickly connect with the connecting port of the spray arm, so that water supply can be achieved after docking, which not only solves the water supply problem but also does not affect the normal sliding of the bowl basket.

[0016] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0017] See attached Figure 1-3 The present application provides a connection structure of a dishwasher spray arm, which includes an inner tank 1, a bowl basket 2, a spray arm 3 and a water supply pipe 4. The bowl basket can slide relative to the inner tank. Specifically, a number of sliding rollers are provided on both sides of the bowl basket. The spray arm is installed on the bowl basket and has a connecting port 31. The water supply pipe is provided on the outside of the inner tank. The inner tank has an installation port. The water outlet 41 of the water supply pipe 4 extends into the interior of the inner tank 1 through the installation port. An adapter 5 fixedly connected to the water outlet is provided on the inside of the inner tank 1. The adapter is connected to the connecting port 31 of the spray arm 3 to supply water. Water supply is achieved by quickly connecting the adapter and the connecting port, and the two are a movable structure. When the user pulls the bowl basket, the connecting port is naturally separated from the adapter.

[0018] The connection port of the spray arm 3 is connected to a sealing sleeve 6, which is provided with an elastic interface. The adapter 5 is connected to the elastic interface. When the elastic interface is connected to the adapter, it is tightly attached to its outer wall, thereby enhancing the sealing performance of the connection between the adapter and the spray arm to avoid water leakage. The sealing sleeve can be made of food-grade silicone material, rubber material, plastic, etc.

[0019] The sealing sleeve 6 is sleeved on the connecting port 31, and an annular boss 7 is provided on the edge of the connecting port. The sealing sleeve has an annular connecting groove that cooperates with the annular boss. With the cooperation of the annular connecting groove and the annular boss, it can be ensured that the sealing sleeve is tightly connected to the spray arm; in addition, when the sealing sleeve is aged or damaged and the sealing performance becomes poor, it can be easily replaced.

[0020] The water outlet 41 has an external thread structure, and the adapter 5 has an internal thread connection port that cooperates with the external thread structure. The adapter only needs to tighten the water outlet to fix the water outlet on the inner tank wall. The threaded structure has the advantage of easy installation and disassembly.

[0021] A sealing ring 8 is provided on the outside of the installation port, and the sealing ring is sleeved on the water outlet. When the adapter 5 is connected to the water outlet 41, the sealing ring is pressed tightly. The sealing ring can strengthen the sealing of the connection between the installation port and the water outlet to prevent water leakage in the inner tank.

[0022] The water inlet 42 of the water supply pipe 4 is connected to the water diversion valve 10 through the water delivery pipe 9. A number of anti-detachment ribs 11 are distributed on the edge of the water inlet. The water delivery pipe can be a soft pipe, which is convenient for arranging its direction according to the internal structure of the dishwasher. The anti-detachment ribs can prevent the water delivery pipe from loosening from the water inlet.

[0023] The spray arm 3 is provided with a plurality of elastic buckles 12 , which are used to connect with the bowl basket 2 . The use of the elastic buckles to fix the spray arm has the advantage of being easy to assemble and disassemble.

[0024] The above description is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the content disclosed in the present invention should be included in the protection scope recorded in the claims.
