Technical field

The invention relates to the technical field of a refrigerator ice maker, and particularly provides a mounting structure of a refrigerator and an ice water inlet pipe of the refrigerator.

Background technique

At present, refrigerators with ice machines are becoming more and more popular. The existing refrigerator ice makers are generally installed in the freezer compartment of the refrigerator, which not only facilitates the storage of the obtained ice, but also shares one with the freezer. The evaporator is used to obtain the cold air required for ice making.

Since the ice maker is installed in the freezer compartment, the water inlet pipe for the ice maker must also pass through the freezer compartment of the refrigerator. Since the temperature of the freezer compartment is below the freezing point, in order to prevent the water in the inlet pipe from freezing and blocking the pipeline, the existing refrigerator ice maker usually heats the sponge and aluminum foil outside the inlet pipe to prevent the pipe from freezing; Some are designed to achieve better antifreeze effect and an electric heating layer is placed outside the tube.

It can be seen that although the water inlet pipe structure of the above existing refrigerator ice maker can achieve more or less anti-freezing effect, the structure of the water inlet pipe is relatively complicated, the design is tedious, and the manufacturability is poor, which not only increases material cost and installation cost, but also increases the material cost and installation cost.

detailed description

The specific embodiments of the present invention are further described in detail below with reference to the drawings and embodiments. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

In the description of the present invention, it should be noted that the term "connecting" should be understood broadly, unless it is specifically defined and defined, for example, it may be a fixed connection, a detachable connection, or an integral connection; They are directly connected or indirectly connected through an intermediary. The specific meaning of the above terms in the present invention can be understood in a specific case by those skilled in the art.

As shown in FIG. 1 , an installation structure of an inlet pipe of a refrigerator ice maker 4 according to an embodiment of the present invention includes an inlet pipe 1 , the inlet pipe 1 is disposed on a side wall of the refrigerator, and the inlet pipe 1 is located outside the side wall of the refrigerator. One end is for communicating with the water source 5, and one end of the inlet pipe 1 penetrating the side wall of the refrigerator extends obliquely downward for communication with the ice maker 4 located in the freezing chamber, thereby being introduced by the water source 5. After flowing into the partial inlet pipe 1 located in the refrigerator, the ice water can be poured downward into the ice maker 4 by the influence of gravity. Due to the large specific heat capacity of the water, part of the inlet pipe 1 located in the refrigerator is It extends obliquely downward, so that the ice making water does not form ice during a short period of time from entering the freezer compartment of the refrigerator to flowing into the ice maker 4.

Wherein, the top side of the partial drain pipe which is disposed on the inner side of the side wall of the refrigerator has a notch 11 which may be a hole-like structure which is only opened on the top side of the part of the inlet pipe 1, or may be in the direction of water flow. a long trough-like structure having a certain extension; the function of the notch 11 is to make a part of the inlet pipe 1 which is inserted in the refrigerator into an open structure, or to make the whole inlet pipe 1 have an open structure as a whole. Therefore, the phenomenon of incomplete drainage in the pipe due to the influence of the air pressure existing in the closed pipe can be avoided, and the phenomenon of the liquid hanging inside the pipe can be largely eliminated, thereby without any heat insulation and heating structure. It can also effectively prevent ice from freezing in the inlet pipe 1 and save costs.

In addition, in the direction of the water flow, the front end of the notch 11 preferably extends to the drainage end of the inlet pipe 1, that is, the opening of the notch 11 passes through the drainage end of the inlet pipe 1, so that the drainage pipe is lacking. The portion from the beginning of the mouth 11 to the drain end is in the form of a groove-like structure with an opening upward, so that once the liquid flow flows into the portion of the notch 11, it is no longer blocked by the air pressure during the subsequent entry into the ice maker 4. It will flow more smoothly into the ice machine 4.

Further, the rear end of the notch 11 preferably extends to a position close to the inlet pipe 1 and the side wall of the refrigerator, that is, the notch 11 is almost present on the portion of the inlet pipe 1 that is completely inserted into the refrigerator, so that the portion inserted into the refrigerator is inserted. The inlet pipe 1 has a groove-like structure with an opening facing upward as a whole. Since there is almost no tubular section in the partial inlet pipe 1 inserted into the refrigerator, the possibility of liquid accumulation in the portion of the inlet pipe 1 in the freezer compartment can be effectively prevented, and the occurrence of ice blockage of the inlet pipe 1 is more effectively prevented. .

Further, as shown in FIG. 2, a part of the water inlet pipe 1 located outside the side wall of the refrigerator preferably extends downward, that is, a part of the water inlet pipe 1 that passes through the refrigerator may extend vertically downward or obliquely downward. Thus, the portion of the inlet pipe 1 passing through the side wall of the refrigerator becomes the highest point of the entire inlet pipe 1, and the inlet pipe 1 inserted into the refrigerator does not have an upstream region, and the ice making water flows into the refrigerator. After part of the inlet pipe 1, the power to continue to flow forward is no longer derived from the pressure inside the pipe, but from its own gravity, freely flowing downward in the open water tank, even if it is located outside the refrigerator. The water in the water pipe 1 stops flowing, and even the phenomenon of backflow does not affect the evacuation of a part of the water inlet pipe 1 located in the refrigerator.

Since the front end of the notch 11 extends to the drain end of the inlet pipe 1, the ice making water begins to flow downward under the action of gravity after flowing into the notch 11, so that the speed of the water flow becomes faster and faster. Under the condition of the same flow rate, the faster the water flow rate, the lower the water flow rate relative to the water level on the bottom side of the inlet pipe 1, so the closer to the downstream position, the higher the requirements on the height of the inlet pipe 1 on both sides of the water flow. The lower, that is, in the direction in which the water flows, the width of the notch 11 can be gradually increased to match the characteristics of the water flow speed, so that the notch 11 is formed on the inlet pipe 1 by the process of turning, cutting, etc. The cutting path may be a straight line at an angle to the axis of the portion of the inlet pipe 1, whereby the notch 11 can be conveniently formed at one time.

The top side of the drain end of the inlet pipe 1 may be a beveled structure 12, which can enlarge the water discharge area of the water outlet end of the inlet pipe 1, thereby reducing the water discharge resistance and ensuring that the water flow velocity is not affected, and preventing the portion from entering The water pipe 1 has a phenomenon of hanging liquid.

The inlet pipe 1 extends outwardly from the connecting portion 2, that is, the connecting portion 2 and the inlet pipe 1 are integrally formed; two holes can be formed in the connecting portion 2, and the connecting portion 2 and the refrigerator are connected by two screws Side wall connection. The connecting portion 2 increases the contact area between the water inlet pipe 1 and the refrigerator, and the connecting portion 2 is integrally formed with the water inlet pipe 1, so that the connection strength between the connecting pipe and the side wall of the refrigerator can be improved. Installation is also easier. A sealing sponge 3 may be interposed between the connecting portion 2 and the side wall of the refrigerator for sealing the opening of the inlet pipe 1 and the opening of the side wall of the refrigerator to prevent the cold air of the refrigerator from leaking out. And the connecting portion 2 is preferably located inside the side wall of the refrigerator, so that the sealing effect is better.

The embodiment of the invention further provides a refrigerator, which comprises the installation structure of the water inlet pipe of the refrigerator ice maker 4 as described above, and the installation structure is not only easy to operate, but also the design of the notch 11 of the inlet pipe 1 is effectively avoided. The risk of ice blocking, while saving the wrapping of sponge and aluminum foil in the prior art, improves reliability and manufacturability, and reduces manufacturing costs. The above is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of the present invention. It should also be considered as the scope of protection of the present invention.
