Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The first embodiment is as follows:

as shown in fig. 1 to 4, the present embodiment provides a dishwasher including a washing chamber, a spray arm assembly disposed in the washing chamber, and a circulating water pipe 1 for supplying water to the spray arm assembly. The spray arm component comprises a spray arm 2 and a connector 3 connected with the spray arm 2, and the connector 3 is connected with the circulating water pipeline 1. The circulating water pipeline 1 supplies water to the spray arm 2 through the connector 3.

Connector

3 and 1 both of circulating water pipeline are provided with separation blade 4, and when circulating water pipeline 1 supplied water to spray arm 2, the separation blade was opened, and circulating water pipeline 1 intercommunication spray arm 2 when circulating water pipeline 1 stopped to supply water to spray arm 2, separation blade 4 closed, and circulating water pipeline 1 cuts off with spray arm 2.

Specifically, the dish washer of this embodiment specifically is a basin dish washer, it is formed by basin 5 to wash the chamber, separation blade 4 sets up in circulating water pipeline 1's tip, separation blade 4 opens, circulating water pipeline 1 intercommunication spray arm 2, supply water to spray arm 2 in order to satisfy circulating water pipeline 1, and stop supplying water to spray arm 2 when circulating water pipeline 1, separation blade 4 closes in order to cut off circulating water pipeline 1 and spray arm 2, prevent that the sewage refluence in the circulating water pipeline 1 from getting into the inner bag, guarantee clean effect in the inner bag, promote user experience.

In this embodiment, as shown in fig. 1, the sink dish washer further includes a lower water cup 51 connected to the lower water port of the sink 5, and a filter 52 is provided in the lower water cup 51. In order to make full use of the space, the circulating water pipe 1 is arranged in the sewage cup 51 and penetrates the filter 52 in the axial direction. It will be readily understood that in other embodiments, the circulating water pipe 1 may be disposed not in the drain cup 51 but in the water tank 5 at a position outside the drain cup 51, so as to separate the circulating influent water from the drain water filtering structure.

It will be appreciated that the dishwasher may also be a table dishwasher or an in-line dishwasher, the washing chamber being formed by a dishwasher liner; the stop piece 4 may also be provided at the end of the connecting head 3.

As shown in fig. 3-5, the circulating water pipe 1 has a water passing opening 11, the connector 3 has a communication opening 31 matched with the water passing opening 11, the blocking piece 4 includes a fixed portion 41 and a movable portion 42, the fixed portion 41 is clamped between the connector 3 and the circulating water pipe 1, the movable portion 42 is turned over and opened relative to the fixed portion 41 under the action of external force, the water passing opening 11 is communicated with the communication opening 31, the movable portion 42 is covered by self-resetting turning under the loss of external force, and the water passing opening 11 is separated from the communication opening 31. The baffle plate 4 can realize the function of opening and closing the circulating water pipeline 1, can be automatically reset and covered by external force, does not need external force intervention, and is simpler and more convenient to operate.

As shown in fig. 6, the outer diameter D of the movable portion 42 is larger than the radial dimension D2 of the water passing opening 11 and smaller than the radial dimension D1 of the communication opening 31, so that when the circulating water pipe 1 supplies water to the shower arm 2, the movable portion 42 is turned inside the communication opening 31 by water flow impact, and when the circulating water pipe 1 stops supplying water to the shower arm 2, the movable portion 42 is self-restored and covered on the water passing opening 11.

Therefore, when the movable part 42 covers the water passing opening 11 of the circulating water pipeline 1 in a natural state, the movable part 42 can completely close the water passing opening 11 of the circulating water pipeline 1, and residue is completely prevented from entering the circulating water pipeline 1. The radial dimension of the movable portion 42 may not be limited in relation to the water passage diameter of the connecting head 3, and the shutter 4 may be opened manually. For example, when it is required to convert a general sink into a bowl sink, the movable portion 42 is manually turned over so that the movable portion 42 is overlapped on the fixed portion 41 to open the shutter 4, and then the shower arm assembly is connected to the circulating water pipe 1. After the spraying arm assembly is connected to the circulating water pipeline 1, the movable part 42 is positioned outside the joint of the connector 3 and the circulating water pipeline 1, and the overturning state of the movable part 42 can be kept, so that the blocking piece 4 is kept in an opening state. When the bowl washing tank is required to be converted into a common water tank, the spraying arm assembly is detached from the circulating water pipeline 1, the movable part 42 covers the water passing port 11 of the circulating water pipeline 1 under the elastic action or manual overturning, and the blocking piece 4 is closed.

As shown in fig. 6, the inner diameter of the circulating water pipe 1 near the water gap 11 is smaller than the inner diameter of the circulating water pipe 1 far from the water gap 11, so that when the water in the circulating water pipe 1 flows from the position far from the water gap 11 toward the water gap 11, the inner diameter of the circulating water pipe 1 tends to become smaller, so that the flow velocity at the water gap 11 is increased, the impact of the water flow at the water gap 11 is increased, and the opening of the movable portion 42 is facilitated.

As shown in fig. 6, the upper surface of the movable portion 42 is an arc-shaped surface, the thickness of the movable portion 42 is reduced from the middle to the outer periphery, the height of the outer edge of the movable portion 42 is not lower than that of the end portion of the circulating water pipe 1, the thickness of the middle of the movable portion 42 is thick, the thickness of the middle of the movable portion 42 is thin, the thickness of the joint between the movable portion 42 and the fixed portion 41 is small, the movable portion 42 is elastically overturned relative to the fixed portion 41, water flow, residues and the like are conveniently moved from the middle of the movable portion 42 to the edge, and when no water flow impacts the movable portion 42, the upper surface of the curved structure can promote the movable portion 42 to restore the.

As shown in fig. 5 and 6, the fixing part 41 is installed on the circulating water pipe 1, the end of the circulating water pipe 1 is provided with an installation groove 12 matching with the fixing part 41, and the fixing part 41 is fixed in the installation groove 12 such that the upper surface of the fixing part 41 is flush with the end of the circulating water pipe 1. Wherein, the fixed part 41 is connected to one side of the movable part 42, so that the movable part 42 can be turned over relative to the fixed part 41 to open the water gap 11 for water supply.

As shown in fig. 5 and 6, the fixing portion 41 is embedded in the mounting groove 12, so as to keep the position of the fixing portion 41 stable, and further ensure the stability of the blocking sheet 4. The fixing portion 41 is sandwiched between the end surface of the circulating water pipe 1 and the end surface of the connector 3, and when the upper surface of the fixing portion 41 is set to be flush with the end wall of the circulating water pipe 1, the fixing portion 41 can be prevented from affecting the connection of the connector 3 and the circulating water pipe 1, and the connection reliability of the connector 3 and the circulating water pipe 1 is ensured.

The separation blade 4 is made of rubber, the separation blade 4 and the end wall of the circulating water pipeline 1 are subjected to secondary injection molding, and the fixing part 41 is embedded in the mounting groove 12 and integrally formed with the end wall of the circulating water pipeline 1.
