Description

Refrigeration equipment

technical field

The utility model belongs to the technical field of refrigeration equipment, and specifically provides a refrigeration equipment.

Background technique

Compared with conventional -18°C cryopreservation, the low temperature of -40°C to -80°C has a better preservation effect on food materials, especially meat. For this reason, some refrigeration equipment (refrigerators or freezers) are provided with a low-temperature space, but because the door seal on the existing door body is not absolutely sealed, when the ambient temperature and humidity are high, water vapor in the external environment can easily penetrate into the low-temperature space through the door seal, resulting in a large amount of frost in the low-temperature space, which affects the use of users.

For this reason, existing low-temperature compartments generally adopt double-layer doors and double-layer door seals. When the external environment is high-temperature and high-humidity, the water vapor in the external environment easily enters between the two layers of doors through the outer door seal, and frosts on the outer surface of the inner door. At the same time, a small amount of water vapor will also enter the low-temperature compartment through the inner door seal, resulting in frosting in the low-temperature compartment, affecting the use of users.

Detailed ways

It should be understood by those skilled in the art that the embodiments described below are only some embodiments of the present utility model, rather than all embodiments of the present utility model. This part of embodiments is intended to explain the technical principle of the present utility model, and is not intended to limit the protection scope of the present utility model. Based on the embodiments provided by the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts should still fall within the protection scope of the present utility model.

It should be noted that, in the description of the present utility model, terms such as "center", "upper", "bottom", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", "outer" and other terms indicating direction or positional relationship are based on the direction or positional relationship shown in the drawings, which are only for the convenience of description, rather than indicating or implying that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be interpreted as a limitation of the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and should not be construed as indicating or implying relative importance.

Further, it should be noted that in the description of the present utility model, unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediary, or it can be an internal connection between two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

In addition, it should be noted that in the description of the present utility model, the terms "coldness" and "heat" are two descriptions of the same physical state. That is, the higher the "cooling capacity" of a certain object (such as evaporator, air, condenser, etc.), the lower the "heat" it has, and the lower the "cooling capacity", the higher the "heat" it has. A target absorbs "coldness" and releases "heat" at the same time, and releases "coldness" while absorbing "heat". An object preserves "coldness" or "heat" in order to keep the object at its current temperature. "Cooling" and "heat absorption" are two descriptions of the same physical phenomenon, that is, an object (such as an evaporator) absorbs heat while cooling.

Finally, it needs to be explained that in the present utility model, the freezing and refrigerating equipment may be a refrigerator, a freezer, or any other feasible freezing and refrigerating equipment.

The first embodiment of the present utility model will be described in detail below with reference to FIG. 1 .

What needs to be explained before is that, for the convenience of description, and in order to enable those skilled in the art to quickly understand the technical solution of the utility model, only the technical features that are strongly related (directly related or indirectly related) to the technical problem to be solved by the utility model and/or the technical concept will be described in the following, and the technical features that are weakly related to the technical problem to be solved by the utility model and/or the technical concept will not be repeated. Since the weakly related technical features belong to common knowledge in the field, even if the utility model does not describe the weakly related features, the disclosure of the utility model will not be insufficient.

For example, in the present utility model, the refrigerating equipment must include a compressor, a condenser, a capillary tube or an electronic expansion valve, and these components are essential components of the refrigerating equipment, and are well known to those skilled in the art. Even if they are not further elaborated below, those skilled in the art can also arrange the above-mentioned components at corresponding positions in the refrigerating equipment according to common knowledge.

As shown in FIG. 1 , in the first embodiment of the present utility model, the refrigerating equipment includes a cabinet 100 , a first evaporator 210 , a second evaporator 220 , a first circulation fan 310 , an auxiliary fan 320 and a door assembly 400 .

Continuing to refer to FIG. 1 , the box body 100 defines a first refrigerated compartment 101 , a second refrigerated compartment 102 and a first storage compartment 103 . The first evaporator 210 is disposed in the first refrigeration compartment 101 for cooling the first storage compartment 103 . The second evaporator 220 is arranged within the second refrigerated compartment 102 .

Wherein, the first storage compartment 103 is a cryogenic compartment, and the temperature inside it can reach -40°C to -80°C.

Further, the first circulation fan 310 is arranged in the first refrigerating compartment 101 , or on the air channel plate between the first refrigerating compartment 101 and the first storage compartment 103 . The first circulation fan 310 is used to drive the air in the first refrigerating compartment 101 cooled by the first evaporator 210 into the first storage compartment 103 , and drive the air in the first storage compartment 103 to flow back into the first refrigerating compartment 101 to be refrigerated by the first evaporator 210 again.

In addition, in other embodiments of the present invention, those skilled in the art can omit the setting of the first circulation fan 310 as needed, and make the first evaporator 210 cool the first storage compartment 103 by direct cooling instead of air cooling.

As shown in Figure 1, in the first embodiment of the present utility model, the door assembly 400 includes a first door body 410 and a second door body 420, the first door body 410 is used to cover the first storage compartment 103, the second door body 420 is arranged on the outside of the first door body 410, and a door gap 430 is formed between the first door body 410 and the second door body 420, the door gap 430 communicates with the second refrigeration compartment 102, so that the air in the door gap 430 and the second refrigeration compartment 10 2 cycle flow.

Continuing to refer to FIG. 1 , in the first embodiment of the present utility model, the box body 100 also defines an air supply channel 104 that communicates the second refrigerated compartment 102 with the door gap 430 , so that the air in the second refrigerated compartment 102 enters the door gap 430 through the air supply channel 104 . Further, the box body 100 also defines a return air channel 105 , which communicates the door gap 430 with the second refrigerated compartment 102 , so that the air in the door gap 430 flows back into the second refrigerated compartment 102 through the return air channel 105 .

Continuing to refer to FIG. 1 , the auxiliary fan 320 is arranged in the second refrigerated compartment 102 , and the auxiliary fan 320 is used to drive the air in the second refrigerated compartment 102 to flow to the air supply channel 104 and then to the door gap 430 . Under the action of the auxiliary fan 320 , the air in the door gap 430 flows back into the second refrigerated compartment 102 through the return air passage 105 .

Based on the foregoing description, those skilled in the art can understand that in the first embodiment of the present invention, by making the second refrigerated compartment 102, the air supply channel 104, the door gap 430 and the return air channel 105 sequentially communicated, the air can circulate and flow along the following path under the action of the auxiliary fan 320: the second refrigerated compartment 102 → the air supply channel 104 → the door gap 430 → the return air channel 105 → the second refrigerated compartment 102. When the air flows into the second refrigerated compartment 102, it will be cooled by the second evaporator 220, so that the water vapor in the air will frost on the second evaporator 220, thereby reducing the water vapor in the air, and then reducing the probability of water vapor frosting in the door gap 430. Further, the water vapor entering the first storage compartment 103 is reduced, thereby weakening or avoiding the occurrence of frost in the first storage compartment 103 .

Further, when there is a lot of frost on the second evaporator 220 , the refrigerating equipment turns on the defrosting function of the second evaporator 220 , so as to melt the frost on the second evaporator 220 .

Optionally, the freezing and refrigerating equipment includes an electric heating device for heating the second evaporator 220, so as to melt the frost on the second evaporator 220 through the electric heating device.

Referring to Fig. 2, the refrigerating and freezing equipment in the second embodiment of the present invention will be described in detail.

Optionally, the second storage compartment 106 is a freezer compartment.

Continuing to refer to FIG. 2 , the second door body 420 is also used to close the second storage compartment 106 , so that the second storage compartment 106 communicates with the door gap 430 , thereby avoiding setting the air supply channel 104 .

In addition, in other embodiments of the present utility model, those skilled in the art can define the second storage compartment 106 and the air supply channel 104 at the same time in the box body 100 according to needs.

The second circulation fan 330 is used to drive the air in the second refrigerated compartment 102 into the second storage compartment 106 , part of the air in the second storage compartment 106 directly flows back to the second refrigerated compartment 102 , and the other part flows to the door gap 430 , and then returns to the second refrigerated compartment 102 through the return air passage 105 .

Based on the foregoing description, those skilled in the art can understand that, compared with the first embodiment, the second embodiment of the present utility model can make air flow along the following path: second refrigerated compartment 102→second storage compartment 106→door gap 430→return air passage 105→second refrigerated compartment 102. Because the cold air flows through the second storage compartment 106 first, and then flows to the door gap 430 , the refrigerating device in the second embodiment also improves the utilization rate of the cooling capacity generated by the second evaporator 220 .
