Description

TECHNICAL FIELD

[0001] The utility model relates to laundry detergent adding technical field, especially a laundry detergent adding device. BACKGROUND

[0002] The laundry detergent adding device is an important component of the washing machine. The laundry detergent adding device usually includes a water injection tank, a distributor and a detergent box. The distributor is provided with multiple chambers for storing different types of detergents, such as granular detergent, liquid detergent and softener. The detergent box is usually marked with Chinese characters or symbols to distinguish different adding compartments.

[0003] In order to accurately add detergent according to washing needs, improve washing effect and reduce detergent waste, a laundry detergent quantitative adding device has emerged as the times require. For example, a liquid detergent feeding device disclosed in patent No. CN217351861U includes a water outlet pipe connected between the water inlet and the inner drum of the washing machine. The water outlet pipe is provided with an electromagnetic valve and a vane wheel in sequence according to the water flow direction. The output end of the vane wheel is provided with a pump body. The liquid inlet of the pump body is connected with the liquid detergent box through a first conveying pipe. The liquid outlet of the pump body is connected with the inner drum of the washing machine through a second conveying pipe. The second conveying pipe is provided with a flow meter.

[0004] However, in the above-mentioned scheme and the scheme with the distributor, the detergent and water are directly added into the washing machine cylinder at the same time, which causes the newly added detergent to contact the clothes before contacting the water. After the clothes absorb the water, the detergent contacts the water and dissolves. The detergent dissolving time is relatively long. In order to achieve uniform distribution of the detergent on the clothes in the washing machine, the washing time needs to be prolonged, and the washing efficiency is not high. SUMMARY

[0005] In view of the problem that the detergent is added into the washing machine without being dissolved, prolonging the washing time and reducing the washing efficiency, the utility model provides a laundry detergent adding device.

[0006] To solve the above-mentioned problems, the utility model adopts the technical scheme that,

When in use, the detergent is placed in the hopper, the flow meter and the second valve are provided to ensure the quantitative addition of the detergent, the detergent and water injected from the injection pipe are mixed and dissolved in the box body by the stirring and conveying mechanism, and then discharged into the washing machine through the discharge pipe, thereby avoiding the contact of the undissolved detergent with the clothes, reducing the washing time and improving the washing efficiency.

[0008] Preferably, the hopper is fixedly arranged in the middle of the fixed plate, and the two ends of the fixed plate are fixedly arranged on the inner sides of the left and right side walls of the box body, so as to ensure the mixing space of the detergent added by the hopper and the water in the box body.

[0009] Preferably, the hopper is in the shape of a frustum of a cone, and the conduit penetrates through the fixed plate. The hopper in the shape of a frustum of a cone facilitates the addition of the detergent and the outflow of the detergent through the conduit.

[0010] Preferably, the stirring and conveying mechanism comprises a rotating shaft rotatably arranged in the middle of the rear wall of the box body, a spiral blade fixedly arranged on the outer wall of the rotating shaft, a motor connected to the rotating shaft after penetrating through the rear wall of the box body, and a discharge pipe arranged on the bottom wall of the box body close to the rear wall. The stirring and conveying mechanism further comprises a controller arranged on the outer side of the panel, and the controller is electrically connected to the motor, the flow meter on the conduit, the first valve and the second valve. The spiral blade can be used to mix the detergent and the water in the box body, and the mixed detergent and water can be discharged from the discharge pipe.

[0011] Preferably, the stirring and conveying mechanism further comprises a heating assembly, the heating assembly comprises a heating wire arranged in the box body, and a partition plate is arranged in the box body to match the heating wire. The heating wire is electrically connected to the controller. The partition plate provides a space for the arrangement of the heating wire, avoids the contact of the heating wire with the water and the detergent, and provides a high temperature for the mixing of the detergent and the water in the box body, thereby further reducing the dissolution time of the detergent.

[0012] Preferably, the partition plate, the box body and the panel form a closed space in the shape of a triangle in cross section, and the heating wire is arranged in the closed space. The arrangement of the heating wire in the closed space reduces the occupation of the mixing space of the water and the detergent in the box body.

[0013] Preferably, a baffle is arranged above the motor, the baffle is in the shape of an inverted concave letter, and the baffle is fixedly arranged on the rear wall of the box body. The baffle provides protection for the motor and avoids the contact of the motor with the water.

[0014] Preferably, a taking and placing groove is arranged on the panel. The taking and placing of the box body is facilitated, and the addition of the detergent in the hopper is facilitated.

[0015] Through the above technical scheme, the advantages of the washing machine detergent adding device are as follows: the detergent and water are mixed and dissolved in the box body through the setting of the stirring and conveying mechanism, and then enter the washing machine, avoiding the contact of the undissolved detergent with the clothes, reducing the washing time, and improving the washing efficiency.
