Example Embodiment

[0030] Example one

[0031] Such as Figure 1 to Figure 3 As shown, the detergent dispensing device described in the embodiment of the present invention includes a water box 1 and a liquid storage box 2 installed inside the water box 1. The top of the water box 1 is composed of a cover plate, and the inside of the cover plate The hollow chamber is provided with an inlet flow channel 32 for injecting water into the liquid storage box 2. A ring of inner ribs 5 is provided on the outer circumference of the inlet flow channel 32, and a ring of outer ribs 6 is provided on the outer circumference of the cover plate. It is spaced from the outer ribs 6 to form a closed chamber extending along the outer circumference of the cover plate. The entire closed chamber passes through. The inside of the closed chamber is provided with a through hole 35, and the closed chamber communicates with the outside of the cover through the through hole 35. .

[0032] In the embodiment of the present inventi...

Example Embodiment

[0034] Example two

[0035] Such as Figure 1 to Figure 4 As shown, the detergent dispensing device described in the embodiment of the present invention is installed on a washing machine and automatically dispenses detergent solution into the washing machine. The detergent dispensing device includes a liquid storage box 2 containing detergent and a A cover plate for injecting water in the liquid storage box 2 is provided with an inlet flow channel 32, and the periphery of the inlet flow channel 32 is provided with an inner rib 5 and an outer rib 6 arranged at intervals, and an inner rib 5 and an outer rib 6 A circle of penetrating closed chamber is formed, and ribs on both sides of the closed chamber separate the water inlet channel 32 from the outside.

[0036] In this embodiment, the cover plate includes a lower cover 3 and an upper cover 4 that are buckled with each other. The upper cover 4 and the lower cover 3 are welded and fixed. The peripheries of the lower cover 3 and the...

Abstract

The invention discloses a detergent feeding device which comprises a water box and a liquid storage box arranged in the water box. The top part of the water box is formed by a cover plate; a water inlet passage for injecting water into the liquid storage box is arranged in a hollow chamber in the cover plate; a circle of sealing chamber extending along the periphery of the cover plate is arrangedon the periphery of the water inlet passage; and the water inlet passage and the outer part of the cover plate are separated by the sealing chamber. According to the detergent feeding device providedby the invention, rib plates on two sides of the sealing chamber achieves a double-layer protection effect on the water inlet passage, so that safety and reliability are realized, and the potential safety hazard of water leakage caused by the cracking of a fusion-welding crack due to the collision happened in the actual production or transportation process of a clothes washing machine is avoided.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a detergent injecting device, in particular, to a washing machine equipped with the detergent injecting device. Background technique [0002] The closed water circuit of the detergent dispensing device on the existing washing machine needs to be welded together by multiple parts to complete a series of complex functions. During the process of welding the two parts to each other, it is necessary to ensure the reliability of the welding. At present, the cover plate The water inlet channel in the cover is welded with a layer of ribs. In the process of actual production and transportation, collisions or other circumstances cause the welding gap to crack, and the water in the cover will seep out of the cracked gap and flow to other parts of the washing machine. , affecting the normal operation of the washing machine and burying hidden dangers to the life safety of...
