Description

The cooling device that comprises evaporimeter

Technical field

The present invention relates to comprise the cooling device of evaporimeter.

Background technology

Cooling device comprises two cabins that are positioned on another, and one is the FF cabin, and another is freezing cabin.Freezing cabin is positioned at the top, and the FF cabin is positioned at the below.The cooling in freezing cabin is to carry out by being coiled in this cabin evaporimeter on every side.In the FF cabin, evaporimeter is arranged in the rear wall.In the refrigerator of routine, the cooling in FF cabin is carried out by free convection.Provide the warm and moistening air that rises along door, so that dehumidify by on the rear surface, cooling off.

Because the evaporator plate in freezing cabin is around this cabin, so the top in the very close FF cabin of the part of this evaporimeter.The temperature value that this situation causes the top surface to reach is lower than the preferred temperature value.Because this adverse influence is so heated wet air is dehumidified on this surface colder than air.Thus, the coagulation that takes place on the top surface is dropped on the food, causes food spoilage.

In prior art embodiments, in order to address the above problem, on top, added heater, this heater is worked when compressor stops.Yet employed heater has adverse effect to the energy consumption of refrigerator.

In prior art embodiments, Spain patent application No. ES2063608 has described a kind of cooling device, it comprises the hardware that is positioned between FF cabin and the freezing cabin, at least a portion heat of this hardware by dissipating by condenser with absorption as heat bridge, thus the temperature of refrigerator cabin top is remained on the dew point.

In another prior art embodiments; Japanese patent application No. JP9026251 has described a kind of showcase for refrigerator; it comprises the airflow path that is positioned between roofing plate and the baffle, and cold air circulates therein and forms dewdrop so that prevent at the upper surface of roofing plate.

Summary of the invention

Target of the present invention is to realize a kind of cooling device, and it has minimized at the lip-deep condensate of FF cabin top and has formed.

In claims, illustrated to reaching the cooling device that target of the present invention realizes.

In cooling device of the present invention, refrigerating evaporator comprises sheet material and the pipe that is installed on this sheet material.This sheet material has adopted tetragonal form, and is set in the inner surface in freezing cabin, makes it cover the bottom in freezing cabin, sidewall and top.Pipe is mounted in the sheet material part corresponding to the sidewall and the top in freezing cabin, has adopted the form of spiraling, but and does not correspond to the bottom of freezing room chamber.In a preferred embodiment of the invention, described pipe is installed into makes the flow direction of cold-producing medium be parallel to the minor face of sheet material, and described pipe is fixed on the sheet material by the method such as welding.

In cooling device of the present invention, there is not pipe to be set in place on sheet material corresponding in the refrigerating evaporator in the part of bottom, freezing cabin, in other words, there is not pipe to be arranged in the part near FF cabin top.Thereby, prevented top than the more supercooling of desired situation, prevented from thus to form coagulation on the waste of energy and the top.In addition, because pipe is to be installed on the sheet material with the form of spiraling, make the flow of refrigerant direction be parallel to the sheet material minor face, so be shaped when covering freezing cabin when sheet material, described pipe only passes through described sheet material sweep once.Therefore, prevented that also described pipe is owing to being out of shape at multi-point bending.

In a preferred embodiment of the invention, described pipe has adopted the variable distance of spiraling to be installed on the sheet material, makes in the tube portion corresponding to freezing cabin sidewall, spirals along with the FF cabin is more close each other near sidewall.

In addition, cooling device comprise compressor, with thermal energy transfer to the condenser of external environment condition and provide and leave condenser so that the capillary of the cold-producing medium that expands.Capillary preferably is attached to refrigerating evaporator by welding.

In an embodiment of the present invention, capillary is connected to refrigerating evaporator, make its with pipe along identical direction.Thereby, come attached described capillary and pipe in firm and easy mode.

In another embodiment of the present invention, capillary is connected to refrigerating evaporator, makes it tilt with respect to pipe.Thereby, reduce cold-producing medium and be delivered to the noise that is produced during the described pipe from capillary.

The specific embodiment

Cooling device (1) comprising:

FF cabin (2) wherein is placed with food to be cooled;

Freezing cabin (3), the case that it is configured as front opening has bottom, top, rear wall and sidewall, and is arranged on the top of FF cabin (2), and wherein place and remain freezing food, its temperature is retained as and is lower than FF cabin (2);

Evaporimeter (4), it is set on the rear wall of FF cabin (2), and absorbs the heat energy in the FF cabin (2); And

Refrigerating evaporator (5), the heat energy (Fig. 1) in its absorption refrigerating cabin (3).

Refrigerating evaporator (5) has:

Sheet material (7), it adopts tetragonal form, is the case of front opening and open rearward end by bending forming, and is set on the inner surface of freezing cabin (3); And

Pipe (8), its be installed to sheet material (7) the part corresponding to the sidewall and the top of freezing cabin (3) (S C), has adopted the form of spiraling, and be not present in sheet material (7) corresponding in the part (B) of the bottom of freezing cabin (3) (Fig. 2).

In a preferred embodiment of the invention, pipe (8) is mounted to and makes the flow of refrigerant direction be parallel to the minor face of sheet material (7).

Like this, owing to there be pipe (8) not to be set near the top of FF cabin (2), so the top that prevented FF cabin (2) is than the more supercooling of expectation situation, and also prevented the coagulation that causes thus.On the other hand, because pipe (8) is to be installed to sheet material (7) with the form of spiraling, make the flow of refrigerant direction be parallel to the minor face of sheet material (7), so in the time of on sheet material (7) is bent with the inner surface that is set to freezing cabin (3), described pipe (8) only passes through each sweep (H) once.Therefore, prevented that also described pipe is out of shape owing to being bent at multiple spot.

In a preferred embodiment of the invention, pipe (8) is installed into and makes the pitch (d) of its circling coil diminish when the sidewall along freezing cabin (3) moves down.Thereby, the amount of pipe (8) that is arranged in the part (S) of sheet material (7) will reduce, thereby prevented that the heat that may take place is poor in this zone, wherein the part (S) of sheet material (7) is corresponding to the sidewall of freezing cabin (3), be near in the position corresponding to the part (B) of the sheet material (7) of the bottom of freezing cabin (3), in other words, be in the position of the top in close FF cabin (2).

In addition, cooling device (1) comprise compressor, with thermal energy transfer to the condenser of external environment condition and provide and leave condenser so that the capillary (6) of the cold-producing medium that expands.Capillary (6) preferably is attached to refrigerating evaporator (5) by welding.

In an embodiment of the present invention, capillary (6) is connected to refrigerating evaporator (5), makes it parallel with pipe (8).Thereby, provide connection (Fig. 3) between capillary (6) and the refrigerating evaporator (5) in firm and easy mode.

In another embodiment of the present invention, capillary (6) is connected to refrigerating evaporator (5), makes it angled with pipe (8).Thereby, minimized the noise (Fig. 4) that is produced when it enters pipe (8) from the stream of capillary (6) with at a high speed.

It being understood that the present invention is not limited to top the disclosed embodiments, those skilled in the art can easily introduce different embodiment.These embodiment are considered to be in the protection domain that is limited by claim of the present invention.
