Description

Technical Field

[0001] The present disclosure relates to the technical field of dishwashers, and in particular to a connection structure between a top spray arm and an inner water pipe. Background Art

[0002] The dishwasher mainly uses the internal rotating spray arm to spray high-temperature and high-pressure water to directly or indirectly wash the dishes in the dish basket. At the same time, it combines the mechanical flushing such as the divergence, reflection, and splashing of the water flow, and is supplemented by the chemical effects such as the wetting, decomposition, and immersion expansion of the detergent, and the dissolution and thermal shock of hot water to fully wash and clean the dishes to achieve the cleaning effect of the dishes. The dishwashers on the market are mainly equipped with lower spray arms, top spray arms, and middle spray arms. By spraying water at three different positions, the flushing and splashing range of the water flow can be expanded as much as possible.

[0003] The patent with application number 202320618836.2 discloses a connection structure of a top spray arm of a dishwasher, including an inner water pipe and a spray arm, the inner water pipe is provided with a water outlet, the spray arm is provided with a water outlet through hole matching the water outlet, the spray arm is plugged into the inner water pipe through the cooperation of the water outlet through hole and the water outlet, a fixed connecting piece is provided at the end of the water outlet, the spray arm is installed between the inner water pipe and the fixed connecting piece, the fixed connecting piece and the water outlet are detachably connected, the interior of the inner water pipe and the interior of the spray arm are matched and connected with each other, and the connection method in this patent is simple and reliable.

[0004] Since the upper and lower bowl baskets and tableware are placed inside the dishwasher, the space available for installing the spray arm is limited, especially the position of the upper bowl basket. The top spray arm in the above patent is directly installed on the inner water pipe, which requires additional space to be reserved between the upper bowl basket and the inner tank for installing the inner water pipe, making the originally slightly cramped space even smaller. In order to prevent the top spray arm from hitting the tableware when rotating and causing damage to the tableware, the upper bowl basket can only be moved downward, which occupies the space of the lower bowl basket and the middle spray arm and the lower spray arm. In order to ensure that the various spray arms in the dishwasher can be uninterfered when working, the space in the inner tank of the dishwasher can only be increased, which not only increases the cost but also wastes space. Utility Model Content

[0005] In view of the deficiencies or problems existing in the prior art, the present invention provides a connection structure between a top spray arm and an inner water pipe, which can effectively save space in the inner tank of a dishwasher.

[0007] As a preferred embodiment, the connection between the outer pipe and the top spray arm is the first connection point, and the connection between the outer pipe and the inner water pipe is the second connection point. The first connection point and the second connection point are both arranged outside the inner tank.

[0008] As a preferred embodiment, the inner water pipe is provided with a first connector and a first water outlet, the first connector is arranged at the first water outlet, the first connector is a hollow structure, the hollow structure is connected to the interior of the inner water pipe, and the outer pipe is connected to the inner water pipe through the first connector.

[0009] As a preferred embodiment, the first connector is arranged outside the inner container; the outer pipe is plugged or snap-connected with the first connector.

[0010] As a preferred embodiment, the outer pipe includes a first section and a second section which are vertically arranged, and the second section is connected to the first connector.

[0011] As a preferred embodiment, a second connector is provided at one end of the first section away from the second section, and the external pipe is connected to the top spray arm via the second connector; the second connector is provided on the outside of the inner tank.

[0012] As a preferred embodiment, the second connecting head includes a first connecting part and a second connecting part, the first connecting part is plugged into the external pipe, and the second connecting part is connected to the top spray arm.

[0013] As a preferred embodiment, the inner water pipe includes a first water inlet channel and a second water inlet channel, the first water inlet channel is connected to the middle spray arm, and the second water inlet channel is connected to the top spray arm.

[0014] As a preferred embodiment, the length of the second water inlet channel is greater than the length of the first water inlet channel.

[0015] As a preferred embodiment, the first connector is arranged on the top of the inner water pipe, and the first connector is integrally formed with the inner water pipe.

[0016] Compared with existing products, the outer pipe connects the inner water pipe with the top spray arm. The top spray arm and the inner water pipe are arranged inside the inner tank, and the outer pipe is arranged outside the inner tank. The inner water pipe no longer occupies additional space on the top of the inner tank of the dishwasher. The top of the inner water pipe is basically flush with the top spray arm, which can increase the cleaning space and effectively avoid the inner water pipe occupying the space of the inner tank of the dishwasher.
