Refrigerator with a refrigerator body

Technical Field

The utility model belongs to the field of refrigeration equipment, and particularly provides a refrigerator.

Background

Some conventional side-by-side refrigerators have a door body at the left and right sides corresponding to a storage compartment (e.g., a freezing compartment, a temperature-changing compartment, or a refrigerating compartment). The left storage room and the right storage room are not communicated with each other, and a vertical beam is arranged between the left storage room and the right storage room to ensure that doors on the left side and the right side can seal the corresponding storage rooms.

For example, the refrigerator is provided with a refrigerating compartment at an upper portion thereof and a freezing compartment and a temperature changing compartment which are laterally distributed at a lower portion thereof. The upper part adopts an independent door body to seal the refrigerating compartment, and the lower part adopts two door bodies which are opened in opposite directions to seal the freezing compartment and the variable-temperature compartment respectively.

The conventional side-by-side refrigerator having a freezing compartment at a lower portion thereof generally has an evaporator corresponding to the freezing compartment disposed at a rear side of the freezing compartment, resulting in a smaller depth of the freezing compartment and a smaller capacity of the refrigerator.

All other embodiments, which can be obtained by a person skilled in the art without any inventive effort, based on the embodiments provided by the present utility model, shall still fall within the scope of protection of the present utility model.

It should be noted that, in the description of the present utility model, terms such as "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate directions or positional relationships, which are based on the directions or positional relationships shown in the drawings, are merely for convenience of description, and do not indicate or imply that the apparatus or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Further, it should also be noted that, in the description of the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, and can also be communicated with the inside of two elements.

By providing the left storage compartment 110 with at least one left air outlet 111 communicating with the intermediate cooling compartment 130 and providing the left storage compartment 110 with at least one left air return 112 on a side wall opposite to the left air outlet 111, cold air entering the left storage compartment 110 from the left air outlet 111 can pass through more areas in the left storage compartment 110 when flowing to the left air return 112, reducing or even avoiding cold air dead space in the left storage compartment 110. Accordingly, the present utility model also ensures uniformity of the temperature of the left storage compartment 110.

Accordingly, by providing the right storage compartment 120 with at least one right air outlet 121 communicating with the intermediate cooling compartment 130 and providing the right storage compartment 120 with at least one right return air inlet 122 on a side wall opposite to the right air outlet 121, cool air entering the right storage compartment 120 from the right air outlet 121 can pass through more areas in the right storage compartment 120 when flowing to the right return air inlet 122, thereby reducing or even avoiding the occurrence of a cool air dead zone in the right storage compartment 120. Accordingly, the present utility model also ensures uniformity of the temperature of the right storage compartment 120.

Further, by providing the left air outlet 111 on the right side wall of the left storage compartment 110, a supply path of cool air is reduced; by providing the left return air inlet 112 on the left side wall of the left storage compartment 110 and allowing the left return air inlet 112 to communicate with the intermediate refrigeration compartment 130 through the left return air passage 151 and allowing a portion of the left return air passage 151 to be located at the lower side of the left storage compartment 110, the left return air passage 151 is prevented from occupying space in the depth direction of the left storage compartment 110 while ensuring temperature uniformity of the left storage compartment 110.

In addition, in other embodiments of the present utility model, the location of the evaporator 300 and/or the blower 400 may be adjusted as desired by those skilled in the art, such as by positioning the evaporator 300 in the plenum 132 and positioning the blower 400 below the evaporator 300.

Although not shown in the drawings, the refrigerator of the present utility model necessarily includes a refrigerating system including the evaporator 300 to supply cold to the evaporator 300 through the refrigerating system. Wherein, the refrigeration system comprises a compressor, a condenser, a depressurization member and an evaporator 300 which are connected end to end in sequence, so that the refrigerant circularly flows along the following paths: compressor→condenser→depressurization member→evaporator 300→compressor.

Specifically, when the refrigerant flows through the compressor, the refrigerant is compressed by the compressor into a high-temperature and high-pressure state (liquid state or gas-liquid mixed state). When the refrigerant flows through the condenser, the heat is radiated through the condenser, and the temperature is reduced to a low-temperature high-pressure state (liquid state or gas-liquid mixed state). When the refrigerant flows through the pressure reducing member, the refrigerant is throttled and reduced by the pressure reducing member to a low-temperature and low-pressure state (liquid state or gas-liquid mixed state). When the refrigerant flows through the evaporator 300, the evaporator 300 absorbs heat in the external environment, and the refrigerant is warmed up to a high-temperature low-pressure state (gaseous state).

The above-mentioned states of the refrigerant in the compressor, the condenser, the pressure reducing member, and the evaporator 300, that is, the high temperature, the low temperature, the high pressure, and the low pressure of the refrigerant are states of the refrigerant after entering the corresponding parts or before flowing out of the corresponding parts, as compared with states before flowing into the corresponding parts.

Thus far, the technical solution of the present utility model has been described in connection with the foregoing embodiments, but it will be readily understood by those skilled in the art that the scope of the present utility model is not limited to only these specific embodiments. The technical solutions in the above embodiments can be split and combined by those skilled in the art without departing from the technical principles of the present utility model, and equivalent changes or substitutions can be made to related technical features, so any changes, equivalent substitutions, improvements, etc. made within the technical principles and/or technical concepts of the present utility model will fall within the protection scope of the present utility model.

Finally, the refrigerator according to the present utility model is a refrigerator in a broad sense, and includes not only a refrigerator in a so-called narrow sense, but also a fresh-keeping apparatus having a refrigerating and/or freezing function, such as a refrigerator, a freezer, etc.
