The invention will be described in detail below in conjunction with the specific embodiments shown in the drawings. However, the embodiments are not intended to limit the invention, and the structures, methods, or functional changes made by those skilled in the art in accordance with the embodiments are included in the scope of the present invention.

A specific embodiment of the variable temperature converter 100 of the refrigeration apparatus of the present invention will be described with reference to Figs. 1, 2, and 3. In the present embodiment, the greenhouse 100 includes a liner 10 and an evaporator fitted to the liner 10.

It should be noted that the refrigeration device referred to herein may include a common refrigeration device such as a refrigerator, a freezer, a refrigerated wine cabinet, and the like.

The liner 10 includes a top wall 11, a bottom wall 12, a left side wall 13, a right side wall 14, and a rear wall 15, and the top wall 11 is at least one of the left side wall 13, the right side wall 14, and the rear wall 15. An inclined wall (not shown) is connected between the evaporators, and the evaporator is disposed only on the left side wall 13, the right side wall 14, the rear wall 15, and the inclined wall.

As a preferred embodiment, in the present embodiment, the inclined wall includes a left inclined wall 16 connected between the top wall 11 and the left side wall 13, and a right connected between the top wall 11 and the right side wall 14. The inclined wall 17, the evaporators 21, 22, 23 are provided only on the left side wall 13, the right side wall 14, the rear wall 15, the left inclined wall 16, and the right inclined wall 17. The advantage of this arrangement is that since the inclined wall is not connected between the top wall 11 and the rear wall 15, the visual feeling does not feel that the space in the greenhouse 100 is too small, and at the same time, the utilization of the space in the greenhouse 100 is improved.

The angle between the left inclined wall 16 and the top wall 11 is equal to the angle between the right inclined wall 17 and the top wall 11, which is visually more symmetrical and beautiful, and ensures a stable defrosting water discharge effect.

The angle between the left inclined wall 16 and the top wall 11 ranges from 130° to 150°, and the angle between the right inclined wall 17 and the top wall 11 ranges from 130° to 150°. Within this angle range, The drainage and discharge effect of the preferred defrosting water can be ensured. Preferably, the angle between the left inclined wall 16 and the top wall 11 is 150°, and the angle between the right inclined wall 17 and the top wall 11 is 150°, which provides the most symmetrical and beautiful appearance. Good defrosting water diversion effect.

The sum of the areas of the left inclined wall 16 and the right inclined wall 17 is greater than or equal to one-half of the area of the bottom wall 12, and at least the left inclined wall 16 and the right inclined wall 17 are provided in order to ensure the cooling effect of the top portion of the greenhouse 100 space. The area is not less than half of the area of the top wall 11 of the variable greenhouse 100 in the prior art, so that the evaporator with sufficient evaporation area can be matched to meet the designed cooling power requirement. In the present embodiment, the areas of the left inclined wall 16 and the right inclined wall 17 are set to be equal, and the evaporation areas of the evaporators 21 and 22 provided on the left inclined wall 16 and the right inclined wall 17 are also equal. Thus, in the greenhouse 100, the degree of condensed defrosting water on the left inclined wall 16 and the right inclined wall 17 can be kept as uniform as possible to ensure a better drainage effect of the greenhouse 100 as a whole. Moreover, since the evaporation areas of the evaporators 21, 22 disposed on the left inclined wall 16 and the right inclined wall 17 are equal, the cooling of the greenhouse 100 is more uniform, and the separately disposed evaporators 21, 22 can make the cooling of the top of the greenhouse 100 Not too concentrated, the cooling capacity of the evaporators 21, 22 can circulate in the horizontal direction, and can also sink along the left and right inclined walls 16, 17, and the left and right side walls 13, 14 respectively, forming a cold amount. Natural convection up and down, to ensure the balance of the temperature of each zone within the greenhouse.

Considering that the temperature in the portion of the greenhouse 100 close to the opening 18 of the inner casing 10 is relatively high, in the above embodiment, the widths of the left inclined wall 16 and the right inclined wall 17 may be further set to be the opening 18 from the inner casing 10. The direction in which the rear wall 15 extends gradually decreases, so that the evaporator disposed thereon has a larger evaporation area near the opening, so that the temperature in the greenhouse 100 is more uniform, and the cooling effect of the greenhouse 100 is ensured.

Referring to Fig. 4, still another embodiment of the variable greenhouse 100a of the refrigeration apparatus of the present invention will be described. Unlike the above embodiment, in the present embodiment, the evaporator is provided at least on the top wall 11a of the inner casing 10a and the inclined wall. Of course, it is understandable that the term "at least" is used to ensure that the cooling effect provided by the evaporator can provide a full-temperature zone cooling effect of 10 ° C ~ - 18 ° C. Preferably, the evaporation area of the evaporator 24a on the top wall 11a is smaller than the evaporation area of the evaporators 21a, 22a on the inclined walls.

Thus, since the evaporator is provided on the inclined wall, the defrosting water generated thereon is discharged under the guidance of the inclined wall, and the evaporation area of the evaporator 24a on the top wall 11a is relatively small, so that the frosting water droplets The problem of falling is alleviated. Preferably, the evaporation area of the evaporator 24a on the top wall 11a here is much smaller than the evaporation area of the evaporators 21a, 22a on the inclined walls.

As still another preferred embodiment, the inclined wall includes a left inclined wall 16a connected between the top wall 11a and the left side wall (not shown), and is connected between the top wall 11a and the right side wall (not labeled) Right oblique wall 17a.

Accordingly, the present invention also provides a refrigerating apparatus (not shown) which can achieve the advantageous effects of the variable greenhouse 100 of the above embodiments by adopting the variable greenhouse 100 of the refrigerating apparatus described in each of the above embodiments. . Moreover, since no other structure or function of the refrigeration device has been improved, other configurations of the refrigeration device will not be described herein. Through the above embodiments, the present invention has the following beneficial effects:

The variable greenhouse 100 of the refrigeration apparatus provided by the present invention connects the inclined wall between the top wall 11 and at least one of the left and right side walls 14 and the rear wall 15, and the evaporator is disposed on the left and right side walls 14, On the rear wall 15, and the inclined wall, the evaporator disposed on the top wall 11 is replaced by an evaporator provided on the inclined wall, so that a temperature change interval of 10 ° C to - 18 ° C can be realized. Meanwhile, in a more preferred embodiment, since the evaporator is not provided on the top wall 11, the defrosting water which may be generated on the inclined wall may slide down the inclined wall to the bottom of the greenhouse 100, and is discharged outside the greenhouse 100. It will not pollute stored food.
