As shown in fig. 1, in an embodiment of the present invention, the number of the sub water injection pipes 211 is two, that is, the water injection pipe 21 includes a first sub water injection pipe 212 and a second sub water injection pipe 213 which are communicated with each other.

At least one sub water injection pipe 211 has an extension section extending downward into the ice maker 1, so that water in the water injection pipe 21 can flow into the ice maker 1 under the action of gravity when water supply is finished, and the flow rate of water is increased. Preferably, the sub water filling pipe 211 closer to the ice maker 1 has an extension section extending downward into the ice maker 1, and the other sub water filling pipes 211 may have an extension section or no extension section.

Further, the water supply assembly 2 further comprises a multi-way pipe 25, and the sub-water injection pipe 211, the check valve 23 and the water supply pipe 22 are connected through the multi-way pipe 25. The multi-way tube 25 has a plurality of guide ports (not numbered) communicated with each other, and the sub-water injection tube 211, the water supply tube 22, and the check valve 23 are respectively communicated with one guide port.

It can be understood that, in the embodiment where the water supply pipe 22, the sub water injection pipe 211, and the check valve 23 are connected by the multi-way pipe 25, the sub water injection pipe 211 is provided separately from the water supply pipe 22, and one end of the sub water injection pipe 211, which is far away from the ice maker 1, is the first communication port 2111.

Specifically, as shown in fig. 2, 4 and 5, the check valve 23 includes a first housing 231 communicating with the first communication port 2111 and having a through shape, a sealing plug 232 movably disposed in the first housing 231, and a reset member 233 acting on the sealing plug 232, the first housing 231 has a sealing portion 2311 cooperating with the sealing plug 232 to make the check valve 23 in a closed state, and a moving portion 2312 connected between the sealing portion 2311 and the first communication port 2111 for moving the sealing plug 232 under the action of water or the reset member 233, and an outer diameter of the sealing plug 232 is smaller than an inner diameter of the moving portion 2312.

Wherein the sealing portion 2311 refers to a portion having a shape and an inner diameter matched with the sealing plug 232 to perform a sealing function, and when the sealing plug 232 is located at the sealing portion 2311, the one-way valve 23 closes the first communication port 2111; the moving portion 2312 refers to a structure having an inner diameter larger than that of the sealing plug 232 and having a gap therebetween all the time, and the check valve 23 opens the first communication port 2111 when the sealing plug 232 is positioned at the moving portion 2312.

During water supply, the sealing plug 232 moves to the sealing portion 2311 under the action of the water pressure in the water supply pipe 22 and/or the water injection pipe 21, and the first communication port 2111 is closed, so that the water in the water supply pipe 22 can be conveyed into the ice maker 1; after the water is delivered, the reset member 233 drives the sealing plug 232 to move to the first communication port 2111 to the position where the first communication port 2312 is located, and opens the first communication port 2111, so that the residual water in the water injection pipe 21 can flow into the ice maker 1 under the action of self weight, no residual water is left in the water injection pipe 21, the phenomenon that the residual water in the water injection pipe 21 freezes to cause pipeline blockage is avoided, and the water-saving effect is achieved.

When the water supply is finished, the reset member 233 drives the sealing plug 232 to move to the moving portion 2312, and at this time, the first housing 231 is in a conduction state along the length direction thereof, that is, the one-way valve 232 opens the first communication port 2111, and the water remaining in the water filling pipe 21 can flow into the ice maker 1 under the action of inertia or self weight.

Further, a first guiding post 2321 protruding toward the limiting member 234 is disposed on the sealing plug 232, and a first guiding hole (not numbered) matched with the first guiding post 2321 is disposed on the limiting member 234; a gap is formed between the first guide post 2321 and the first guide hole, and the gap constitutes the hollow portion. During the movement of the sealing plug 232 between the sealing portion 2311 and the moving portion 2312, the first guiding column 2321 and the first guiding hole cooperate to guide the movement of the sealing plug 232 along the radial direction of the first housing 231, so as to enhance the stability of the movement of the sealing plug 232.

In a specific embodiment, the restoring element 233 is a spring, the check valve 23 further includes a spring seat (not numbered) disposed in the first housing 231 and located on a side of the sealing plug 232 facing away from the first communication port 2111, one end of the spring acts on the spring seat, and the other end acts on the sealing plug 232. A gap is formed between the periphery of the spring seat and the first housing 231, or a hollow portion penetrating the spring seat in the longitudinal direction of the first housing 231 is formed on the spring seat.

It will be appreciated that the spring may be attached to the spring seat and/or the sealing plug 232 or may be held directly against the spring seat and/or the sealing plug 232 to effect one end of the spring acting on the spring seat and the other end acting on the sealing plug 232.

When the water pipe 22 delivers water, under the action of water pressure, the sealing plug 232 moves away from the first communication port 2111 to the sealing portion 2312, so that the first housing 231 is in a closed state, and the spring is elastically deformed; when the water supply from the water supply pipe 22 is finished, the water pressure disappears, and the sealing plug 232 moves from the first communication port 2111 to the position where it is located at the moving portion 2312 under the elastic restoring force of the spring, so that the first housing 231 is in a conduction state, that is, the first communication port 2111 is opened.

A second guide post 2322 protruding towards the spring seat is arranged on the sealing plug 232, and a second guide hole (not numbered) matched with the second guide post 2322 is arranged on the spring seat; a gap is formed between the second guide post 2322 and the second guide hole, and the gap constitutes the hollow portion.

During the movement of the sealing plug 232 between the sealing portion 2311 and the moving portion 2312, the second guiding column 2322 is matched with the second guiding hole to guide the movement of the sealing plug 232 along the radial direction of the first housing 231, so that the movement stability of the sealing plug 232 is enhanced.

Further, as shown in fig. 3, 4 and 5, the water supply module 2 further includes an accumulator 24, and the accumulator 24 includes a second housing 241 communicated with the first communication port 2111, a piston 2412 movably disposed in the second housing 241 and dividing the second housing 241 into two cavities 2411, and a driving member 2413 for driving the piston 2412.

The two cavities 2411 are respectively a first cavity close to the first communication port 2111 and a second cavity (not numbered) at an end far from the first communication port 2111. When water is delivered, water enters the first cavity, and under the action of the water pressure of the first cavity, the piston 2412 moves towards the direction far away from the first communication port 2111; after the water is delivered, the driving member 2413 drives the piston 2412 to move in a direction close to the first communication port 2111, so as to push at least part of the water in the water filling pipe 21 to flow into the ice maker 1. The energy accumulator 24 is arranged to provide an initial power for the water in the water filling pipe 21 when the water supply is finished, so that the water can flow into the ice maker 1 more conveniently.

In one embodiment, the driving member 2413 is an elastic member, one end of the elastic member acts on the piston 2412, and the other end of the elastic member acts on the first housing 231. It can be understood that the elastic member may be connected to the first housing 231, or may directly abut against the first housing 231.

Preferably, the elastic member is disposed on a side of the piston 2412 away from the first communication port 2111, so as to prevent water entering the first cavity from impacting the first cavity.
