Description

Low-temperature dehumidification system and efficient and energy-saving refrigerator

Technical Field

The utility model relates to a low temperature system of dehumidifying and energy-efficient freezer.

Background

With the progress of society, the improvement of living standard and purchasing ability of people has higher requirements on the quality, variety and quality of food. Some foods need to be subjected to surface drying treatment before processing (for example, duck embryos of roast ducks need to be subjected to surface drying treatment before roasting), but if the surface drying treatment is carried out at normal temperature, the food quality is affected due to poor sanitation conditions exposed to the environment, so that the dehumidification system can provide a good environmental condition for the food drying treatment. As for the refrigerators sold in the current market, most refrigerators do not have refrigeration and dehumidification integrated refrigerators, most refrigerators have two systems, and the dehumidification and refrigeration systems are mutually independent, so that the manufacturing cost and the refrigerator energy consumption are too high.

Disclosure of Invention

In order to overcome the technical problems, the utility model provides a low-temperature dehumidification system, which comprises a humidity detector, a controller and a dehumidification heating device;

the humidity detector is used for detecting a humidity signal of the refrigerator and sending the signal to the controller;

the controller is used for receiving the humidity signal and comparing the humidity signal with a set value to determine whether the humidity signal exceeds the set value, if so, the controller is used for controlling the humidity reducing and heating device to start to work, and if not, the controller is used for controlling the humidity reducing and heating device to stop working;

wherein, when the dehumidification heating device is started to work, the dehumidification heating device is used for dehumidifying the refrigerator.

Furthermore, the humidity reducing and heating device is a humidity reducing and heating tube;

the utility model also provides a high-efficiency energy-saving refrigerator, which comprises a refrigerating system and the low-temperature dehumidification system, wherein the refrigerating system comprises a compressor, an evaporation pipe, an anti-dew pipe, a condenser, a drying filter, a solenoid valve, a capillary tube and an evaporator, and the dehumidification heating pipe is arranged beside the evaporator and at the air outlet of the refrigerator; the humidity detector is arranged on one side of the evaporator, which is far away from the dehumidification heating tube.

The utility model has the advantages that:

the utility model discloses in, can high-efficiently reduce the inside humidity of freezer when not influencing the freezer cooling. On the other hand, the dehumidification system and the refrigeration system are integrated on the same refrigerator, so that the whole process is simpler and more compact, and the space and the manufacturing cost are saved.

Detailed Description

The present invention will be further described with reference to the following examples, which are only part of the present invention, and these examples are only used to explain the present invention, and do not constitute any limitation to the scope of the present invention.

Referring to fig. 1, a low-temperature dehumidification system includes a humidity detector, a controller, a dehumidification heating device;

the utility model also provides a high-efficient energy-saving freezer, it includes refrigerating system and the low temperature dehumidification system, see figure 2, the refrigerating system includes compressor 1, evaporating pipe 2, dew prevention pipe 3, condenser 4, dry filter 5, solenoid valve 6, capillary 7, evaporimeter 8, the dehumidification heating tube sets up by the evaporimeter and freezer air outlet department; the humidity detector is arranged on one side of the evaporator, which is far away from the dehumidification heating tube.

The utility model discloses the working process of freezer:

and starting the refrigerating system and the low-temperature dehumidifying system. When the low-temperature dehumidification system works, the humidity detector detects a humidity signal of the environment of the refrigerator and sends the humidity signal to the controller, and if the humidity signal received by the controller exceeds a set value, the controller controls the dehumidification heating device to work and the dehumidification starts; and then, the humidity is reduced to a set value, and the controller controls the humidity reducing and heating device to stop working. When the refrigerating system works and the temperature in the cabinet reaches the set temperature, the compressor is stopped, the electromagnetic valve is closed, the temperature in the cabinet rises to the specific temperature, the refrigerating system is started, and the refrigerating cycle is repeated. The utility model discloses an in the freezer, will fall the wet device that generates heat and install in the cabinet, at refrigerating system during operation, utilize to fall the heat extension refrigerating plant operating time that the wet device that generates heat produced to adsorb the moisture that carries in the circulating air in the freezer environment on the evaporimeter, recycle refrigerating system stop work and will defrost the moisture discharge during the defrosting. The air in the refrigerator of the utility model is ensured below the dew point temperature corresponding to the temperature and humidity in the refrigerator when the air in the refrigerator circulates, so as to prevent condensation; the utility model discloses still having designed special water collector that has the drain pipe and installed in the evaporimeter bottom, the box outside still is equipped with the water collector, can be with the timely row of defrosting water outside the box, let moisture natural evaporation, solved the inside problem that produces ponding of freezer.

To sum up, the utility model discloses in, can high-efficiently reduce the inside humidity of freezer when not influencing the freezer cooling. On the other hand, the dehumidification system and the refrigeration system are integrated on the same refrigerator, so that the whole process is simpler and more compact, and the space and the manufacturing cost are saved.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments, and although the present invention has been disclosed with the preferred embodiments, it is not limited to the present invention, and any skilled person in the art can make some modifications or equivalent changes without departing from the technical scope of the present invention.
