1 and 2 are a refrigerator with an ice making function, including a box body 1 , an ice maker 2 and a water injection pipe 3 . The box body 1 is provided with a freezer compartment 11, the ice maker 2 is arranged in the freezer compartment 11, and a water injection port is arranged on the top thereof. The water injection pipe 3 enters the pipe from the position where the rear side wall of the box body 1 is slightly higher than the water injection port, and extends to the water injection port to inject water into the ice maker 2 .

The above method of injecting water from the back of the refrigerator belongs to the horizontal inlet pipe. It is required that the position corresponding to the ice maker 2 in the rear wall space of the box 1 cannot be provided with an air duct, otherwise the inlet pipe of the water injection pipe 3 will be blocked. It can be seen that the horizontal pipe entry method of injecting water from the back of the refrigerator to the ice maker has high requirements on the layout of the air ducts in the box, resulting in relatively large limitations in the layout of the air ducts.

As shown in FIGS. 3-10 , a refrigerator provided by an embodiment of the present disclosure includes a box body 100 , a door body (not shown in the figures), an ice maker 200 , an air duct 400 and a water injection pipe assembly 300 .

The inside of the box body 100 is provided with a refrigerator compartment 120 (first storage compartment), a freezer compartment 110 (second storage compartment), a compressor compartment 130 and an installation space. The refrigerator compartment 120 (first storage compartment), the freezer compartment The 110 (second storage room) and the compressor room 130 are arranged in order from top to bottom and are separated by the installation space. The door is used to open and close the freezer compartment 110 and the refrigerator compartment 120 . The ice maker 200 is installed on the top of the freezer compartment 110, and has a water filling port 210 on the top. The air duct 400 is provided in the installation space of the box body 100 and extends through the rear of the ice maker 200 to block the pipe from the back of the box body 100 . One end of the air duct 400 extends upward to communicate with the refrigerating chamber 120, and the other end extends downward to communicate with the freezing chamber 110. The water injection pipe assembly 300 is disposed in the installation space and extends vertically. The water inlet end extends downward to penetrate into the compressor chamber 130 , and the water outlet end extends upward to the top of the ice maker 200 and communicates with the water injection port 210 . The water inlet end of the water injection pipe assembly 300 may communicate with the water tank, or may communicate with the external water pipe 140 provided on the rear side wall surface of the tank body 100 .

In the refrigerator provided by some embodiments of the present disclosure, the water injection pipe assembly 300 for supplying water to the ice maker 200 is provided on the side of the air duct 400, and the vertically extending air duct 400 is arranged vertically, and the water inlet end thereof is arranged vertically. It is arranged in the compressor room 130, and the whole is a vertical pipe feeding method of water injection from the bottom of the box, which effectively avoids the water injection pipe assembly 300 from restricting the layout of the air pipe 400. The vertical pipe feeding method of injecting water from the bottom of the box has a simple structure, is easy to implement, and does not significantly increase the cost.

In some embodiments of the present disclosure, referring to FIGS. 10 and 11 , the compressor chamber 130 is further provided with a water valve 500 , and the water inlet end of the water injection pipe assembly 300 is communicated with the water valve 500 . In the refrigerators of the prior art, a solenoid valve (ie, a water valve) is generally provided on the water injection pipe for supplying water to the ice maker 200 . Since water is injected from the back of the box body, the solenoid valve is generally located in the middle of the box body 100 . At this point, after opening the door of the freezer compartment 110 or the refrigerator compartment 120, the user will hear obvious operating noise of the solenoid valve, and the user experience is not good. The embodiment of the present disclosure adopts the bottom water injection method of injecting water from the compressor chamber 130. The water valve 500 can be installed in the compressor chamber 130, which is far away from the user. After the user opens the door of the freezer chamber 110 or the refrigerator chamber 120, the Hear the obvious running noise of the water valve 500, which effectively improves the user experience.

In some embodiments of the present disclosure, referring to FIG. 11 , an evaporating dish 600 is further provided at the bottom of the compressor chamber 130 , and the water valve 500 is located above the evaporating dish 600 . When the water valve 500 is working, water drips intermittently. The refrigerators in the prior art are not provided with measures to deal with water dripping from the solenoid valve, which greatly affects the user experience. In the existing refrigerator structure, an evaporating dish 600 is provided at the bottom of the compressor chamber 130 for evaporating the dripping water of the condenser 700 . Therefore, the present disclosure directly utilizes the original structure of the evaporating dish 600 of the refrigerator, and disposes the water valve 500 above the evaporating dish 600, so that the dripping water of the water valve 500 falls on the evaporating dish 600 and is evaporated.

In some embodiments of the present disclosure, referring to FIG. 12 , a condenser 700 is provided above the evaporating dish 600 . The water valve 500 of the present disclosure is located at the side of the condenser 700 and is connected to the side wall of the compressor chamber 130 . The above arrangement facilitates the rational arrangement of various components in the compressor chamber 130 .

The above-mentioned setting method of the water valve 500 is a setting that can only be completed based on the vertical inlet pipe method of water injection from the bottom of the casing (compressor chamber 130) proposed in the present disclosure.

In some embodiments of the present disclosure, referring to FIG. 3 , the upper part of the box body 100 is provided with one refrigerating chamber 120 , and the lower part is provided with two freezing chambers 110 side by side. Referring to FIG. 5 and FIG. 8 , the ice maker 200 is disposed on the side of the freezing chamber 110 close to the water valve 500 .

In some embodiments of the present disclosure, referring to FIG. 7 , the water inlet end of the water injection pipe assembly 300 penetrates from the top of the compressor chamber 130 .

The above arrangement can reduce the length of the water injection pipe assembly 300 as much as possible, reduce the detouring complexity of the water pipe, and make the solution more convenient to implement.

Similarly, in other embodiments, the upper and lower positions of the freezing compartment 110 and the refrigerating compartment 120 can be exchanged. When the refrigerating compartment 120 is located below, the ice maker 200 is provided on the top of the refrigerating compartment 120 .

In some embodiments of the present disclosure, a foam layer is provided in the installation space of the box body 100 . Referring to FIGS. 11-15 , the water injection pipe assembly 300 includes a casing 310 and a water delivery pipe 320 . The sleeve 310 is embedded in the foam layer and forms an integral structure with the foam layer. The first end 311 of the sleeve 310 is the water inlet end, which communicates with the compressor chamber 130 , and the opposite second end 312 is the water outlet end, which communicates with the water injection port 210 . The water delivery pipe 320 can movably extend into the casing 310 from the first end 311 of the casing 310 to transport the water in the water delivery pipe 320 into the water injection port 210 through the second end 312 of the casing 310 .

The water injection pipe assembly 300 proposed in the present disclosure includes a casing 310 and a water delivery pipe 320 . The sleeve 310 is embedded in the foam layer of the box body 100, which can effectively simplify the sealing structure in the pipeline, reduce the difficulty of installation, and maintain the optimal detouring angle. The movable water supply pipe 320 used to extend into the casing 310 is convenient for implementing the method of water injection from the bottom, and is convenient for plugging and maintenance, thereby reducing production and maintenance costs.

In some embodiments of the present disclosure, referring to FIG. 13 , the casing 310 sequentially includes a transition pipe 313 and a water outlet pipe 314 from the first end 311 to the second end 312 . Referring to FIG. 11 , the transition pipe 313 communicates with the compressor chamber 130 through the first fixing seat 330 . Referring to FIGS. 7 and 13 , the water outlet pipe 314 communicates with the top wall 220 of the ice maker 200 through the second fixing seat 340 , so that the water outlet pipe 314 is fixed above the water injection port 210 . Referring to FIG. 9 , the transition pipe 313 extends to a position higher than the water injection port 210 , and is connected with the water outlet pipe 314 at a predetermined angle X to form a structural pipe similar to an “L” shape. In the embodiment of the present disclosure, the transition pipe 313 extends to a position slightly higher than the water injection port 210, and is connected with the water outlet pipe 314 at an included angle of 90-100°.

In some embodiments of the present disclosure, referring to FIGS. 13-15 , the water outlet pipe 314 includes a first pipe section 3141 and a second pipe section 3142 that are integrally formed. The first pipe section 3141 is connected to the second fixing base 340, and the axis of the first pipe section 3141 is perpendicular to the top wall 220 of the ice maker 200 (flush with the top wall of the freezing compartment 110, generally on a horizontal plane). The second pipe section 3142 is connected with the transition pipe 313 , and the second pipe section is connected with the first pipe section 3142 at an included angle Y greater than 90°, which is beneficial to ensure that the water in the water supply pipe 320 flows into the ice maker 200 .

In some embodiments of the present disclosure, referring to FIG. 15 , the port of the first pipe section 3141 is provided with at least one gap 350 along its circumferential direction. Specifically, the notch 350 is a trapezoidal groove with a narrow upper part and a wide lower part, and can also be a circular arc groove. In the actual usage scenario, the nozzle of the thin tube is prone to form a water film accumulation due to negative pressure, and the water film will freeze in a low temperature environment, causing the nozzle to be blocked. The heating device set outside the pipe in the prior art is generally difficult to act on the position of the nozzle, so the common waterproof membrane measure in the prior art is to directly cut the port of the pipe into a large U shape, but such a nozzle outlet angle and range are difficult to achieve. control, does not guide the water well to the water injection port. However, the gap 350 provided in the embodiment of the present disclosure can prevent the accumulation of water film, effectively avoid the blockage of the first pipe section 3141, and will not have a great impact on the water injection angle and range.

In some embodiments of the present disclosure, referring to FIG. 15 , a limiting rib 360 is provided on the second pipe section 3142 , and the limiting rib 360 is located on a side close to the first pipe section 3141 for blocking the water supply pipe 320 from entering the first pipe section 3141 . Since the first pipe section 3141 is close to the freezing chamber 110, the temperature in the pipe is relatively low. Setting the limiting ribs 360 can prevent the water supply pipe 320 from extending into the first pipe section 3141, and prevent the water in the water supply pipe 320 from freezing and blocking the nozzle.

In some embodiments of the present disclosure, referring to FIG. 15 , the limiting rib 360 is provided on the inner top wall of the second pipe section 3142 , and the gap between the bottom surface of the limiting rib 360 and the inner bottom wall of the second pipe section 3142 is smaller than that of the water supply pipe 320 and an inclined surface 3601 is provided on one end away from the first pipe section 3141 , and the inclined surface 3601 is inclined downward from the first end 311 to the second end 312 of the sleeve 310 . The above arrangement can prevent the residual water from staying in the periphery of the limiting rib 360 and the accumulation of ice and growth.

The above are only the embodiments of the present disclosure. It should be pointed out that for those skilled in the art, without departing from the technical principles of the present disclosure, several improvements and substitutions can be made. These improvements and substitutions are also It should be regarded as the protection scope of the present disclosure.
