Description

Detergent delivery mechanism for dish washing machine, door body structure and dish washing machine

Technical Field

The utility model relates to the technical field of dish washers, in particular to a detergent delivery mechanism for a dish washer, a door body structure and the dish washer.

Background

The dish washer has the advantages of good cleaning effect, capability of disinfecting tableware, time saving, labor saving and the like, so that the dish washer is widely used. At present, a dispenser is arranged on a door body of a dish washer, a user opens the door body and then places a detergent in the dispenser, and the dispenser timely puts the detergent into a washing cavity of the dish washer in a washing stage of the dish washer.

As disclosed in chinese patent publication No. CN201921408798.8 (publication No. CN 210961851U), the detergent dispensing device for a dishwasher and the dishwasher are provided with a second check valve for unidirectional conduction of fluid in a direction from the inside of the reservoir to the outside of the reservoir, both of the opening at the other end of the first liquid outlet passage and the opening at the other end of the second liquid outlet passage. The fluid may be a gas or a liquid, and the second one-way valve may allow the corresponding detergent to be pumped from the interior of the corresponding reservoir to the exterior, while blocking water vapor from the interior of the dishwasher from entering the liquid outlet pump, thereby avoiding the water vapor from affecting the performance and lifetime of the liquid outlet pump.

However, under the condition of large pressure in the liquid storage cavity, the opening of the liquid outlet channel can not be completely blocked only by the second one-way valve, and the liquid detergent still flows out from the opening of the liquid outlet channel at the non-throwing moment.

Disclosure of Invention

The first technical problem to be solved by the utility model is to provide a detergent delivery mechanism for a dish washer, which can reduce non-delivery time and detergent flowing out from a discharge hole.

The second technical problem to be solved by the utility model is to provide a door body structure for a dish washer, which is applied to the detergent delivery mechanism, aiming at the current state of the art.

The third technical problem to be solved by the utility model is to provide a dish washer applying the door body structure aiming at the current state of the art.

The technical scheme adopted by the utility model for solving the first technical problem is as follows: a detergent dispensing mechanism for a dishwasher, comprising

The shell is internally provided with a cavity for accommodating the detergent, and the shell is provided with a feed inlet and a discharge outlet which are communicated with the cavity;

the liquid inlet of the pump body is in fluid communication with the cavity, and the liquid outlet of the pump body is in fluid communication with the cavity and the discharge port;

the device is characterized in that a liquid outlet of the pump body is closed in a state that the pump body stops working.

The pump body may take a variety of forms, preferably it is a diaphragm pump or peristaltic pump or a piston pump.

In order to enable the detergent to smoothly flow out of the discharge port in the feeding process, the discharge port is hollow, namely, no other parts are arranged in the discharge port, the flowing of the detergent is not hindered, and the inner diameter of the discharge port is between 4mm and 7 mm. The inner diameter of the discharge hole is larger, so that the detergent can smoothly flow out at the moment of throwing in, the detergent is prevented from remaining, and the detergent flows out of the discharge hole at the moment of non-throwing in.

Because the liquid outlet of the pump body is closed in the state that the pump body stops working, the detergent positioned at the upstream of the liquid outlet of the pump body can not flow to the liquid outlet of the pump body any more, preferably, the liquid outlet of the pump body is close to the discharge outlet, so that the residual detergent between the liquid outlet of the pump body and the discharge outlet of the shell can be reduced as much as possible, and the residual liquid flowing out from the discharge outlet at the moment of non-throwing is further reduced.

Preferably, the distance between the liquid outlet and the discharge outlet of the pump body is between 10mm and 20mm, if the distance is too large, water flow flushing is difficult, and if the distance is too small, the structural process is difficult to arrange and realize.

Preferably, the discharge port is a liquid outlet of the pump body, so that the detergent is directly sealed at the upstream of the liquid outlet of the pump body and cannot flow out at non-throwing time.

In order to further prevent the detergent from flowing out of the discharge port at the non-throwing moment, a one-way valve which can only enable the liquid in the cavity to flow into the discharge port in one way is arranged in the discharge port, and the one-way valve closes the discharge port in a natural state.

The check valve can have multiple structural forms, and simple structure, the central part of discharge gate is equipped with the center ring, the interval between the wall of periphery wall and the discharge gate of center ring forms the discharge channel, the check valve includes the erection column of cartridge in the center ring and locates the baffle of erection column one end, the baffle closes the discharge channel under natural state, the baffle can produce the deformation under the fluid impact effect in the cavity and open the discharge channel. When the feeding time is not the feeding time, the baffle closes the discharging channel, and the liquid dishwashing agent cannot flow out of the discharging channel; when the feeding time is over, the pump body works, the baffle is deformed by the impact of the detergent on the baffle, the discharging channel is opened, and the detergent flows out of the discharging channel.

In order to prevent food residues such as rice grains from accumulating on the top wall surface of the cover plate and being difficult to wash away, the cover plate capable of opening or closing the feed inlet is movably arranged on the shell, and the top wall surface of the cover plate is an inclined surface inclined from top to bottom in a direction away from the feed inlet in a state that the cover plate closes the feed inlet. Thus, the food residues can flow down from the top wall surface of the cover plate under the action of self gravity.

The utility model solves the second technical problem by adopting the technical proposal that: the door body structure applying the detergent delivery mechanism is characterized in that: the door comprises a door body, and the shell is arranged on the door body.

The technical scheme adopted by the utility model for solving the third technical problem is as follows: the dish washer of using above-mentioned door body structure, its characterized in that: the washing machine further comprises a box body, the box body is provided with a washing cavity with an open front side, the door body is movably arranged at the open part of the washing cavity, so that the open part of the washing cavity is opened or closed, and a discharge hole of the cavity faces the washing cavity.

Compared with the prior art, the utility model has the advantages that: in the pump body adopted by the utility model, the liquid outlet of the pump body is closed in a state of stopping working, so that the detergent positioned at the upstream of the liquid outlet of the pump body is blocked by the liquid outlet and cannot flow towards the discharge outlet, and the phenomenon that a large amount of detergent flows out of the discharge outlet at non-throwing time is avoided.
