the refrigerating device comprises an evaporator 41, a compressor 42, an external condenser 43, a water receiving disc 44 and a water receiving disc heating pipe 45; the evaporator 41 communicates with the compressor 42 through a capillary tube; the external condenser 43 is communicated with the exhaust end of the compressor 42;
the evaporator 41 is arranged between the back foaming layer of the freezing chamber 2 and the freezing fan cover 21; a refrigerating fan is also arranged above the evaporator 41 in the freezing air duct; the compressor 42 is installed in a compressor bin at the bottom of the back of the freezing chamber 2; the water pan 44 is arranged at the bottom of the compressor bin corresponding to the compressor 42; an external condenser 43 is arranged at one side inside the compressor bin; an extension pipeline of the external condenser 43 is coiled at the bottom of the water receiving tray 44 to form a water receiving tray heating pipe 45;
when the refrigerating chamber 1 does not refrigerate and the freezing chamber 2 refrigerates, the electric air door 31 in the connecting air duct 3 is closed, and air in the refrigerating chamber 1 is sent into a refrigerating chamber where the refrigerator 41 is located by positive pressure air generated by a refrigerating fan; at this time, the evaporator 41 has a low temperature generally lower than-25 ℃, has a strong dehumidifying capability, quickly removes the moisture in the refrigerating chamber 1, and reduces the relative humidity to 10% or even lower of the refrigerating fan housing; when the refrigerating chamber 1 stops refrigerating, negative pressure is generated in the refrigerating chamber 1, moisture in a door body 1 of the refrigerating chamber cannot be supplemented in time, and the relative humidity is always at a lower level and cannot rise to a high level, so that the average relative humidity is generally maintained between 10% and 30% of a refrigerating fan cover, and food is extremely easy to air dry after being placed in the refrigerating chamber, so that the humidity in the refrigerating chamber 1 is adjusted by adopting an air-conditioning and humidifying device;
the air-conditioning humidifying device comprises an air duct formed by an air duct 51, an air outlet duct 52 and an air inlet duct 53; the upper end and the lower end of the air pipe 51 are respectively communicated with an air outlet pipe 52 and an air inlet pipe 53; the gas pipe 51 is positioned in the foaming layer on the side wall of the refrigerator body; the air outlet pipe 52 is communicated with the refrigerating chamber 1; the air inlet pipe 53 extends into the compressor bin, and the bottommost end of the air inlet pipe 53 is positioned above the water pan 44.
In actual use: when the refrigerating chamber 1 stops refrigerating and the freezing chamber 2 independently refrigerates, the compressor 42 continuously works and the electric air door 31 in the connecting air duct 3 is closed; at the moment, the refrigerating return air duct is communicated with the freezing chamber 2, so that negative pressure is generated in the refrigerating chamber 1; the gas in the refrigerating chamber 1 is sucked into an evaporator cavity where an evaporator 6 is positioned by suction force generated when a refrigeration fan works; when the compressor 42 works, the exhaust end is at high temperature and high pressure, the external condenser 43 is rapidly heated, and the cooling fan rotates; the air suction surface of the external condenser 43 blows heat to the compressor 42 towards the external condenser 43, so that forced convection heat dissipation is realized, and positive pressure is formed on the side of the compressor 42; and the intake pipe 52 is located on the blowing positive pressure surface of the radiator fan; after the defrosting process is finished, defrosting water is accumulated in the water receiving tray 13, when the compressor 42 starts to work, the water receiving tray heating pipe 45 heats and evaporates water in the water receiving tray 44 along with the temperature rise of the external condenser 43, the negative pressure suction force generated by the refrigerating fan and the positive pressure generated by the radiating fan 46 jointly act, so that gas rich in water vapor enters the refrigerating chamber 1 through the gas conveying pipe 51 to supplement necessary gaseous water vapor for the refrigerating chamber 1, and after entering from the gas inlet pipe 52 positioned at the upper layer of the refrigerating chamber 1, the gas is diffused to each part of the refrigerating chamber 1 through the sinking effect, the gas is sucked into the refrigerating return air duct from the refrigerating return air inlet 13, and the air conditioning and humidifying process is finished. The whole process quickly balances the air pressure inside and outside the refrigerating chamber, and prevents the phenomenon that the negative pressure in the refrigerating chamber is not easy to open when passing through a gate.
From a thermodynamic perspective, temperature and absolute humidity determine the relative humidity level of a space. When the common single-system refrigerator operates and the refrigerating chamber refrigerates, most of absolute humidity is brought to the low-temperature evaporator through air circulation to be condensed, and after the refrigeration is stopped, the relative humidity rises slowly and the highest point is low, so that the average relative humidity is too low; as can be seen from the air conditioning theory, the absolute humidity contained in the same relative humidity varies at different temperatures. The higher the temperature, the greater the absolute humidity in the air. Relative humidity refers to the ratio of absolute humidity to the water vapor content of the saturated state of the temperature expressed as a percentage.
Referring to fig. 9, the absolute humidity refers to the amount of water vapor contained in the air, and the table corresponding to the relative humidity and the absolute humidity shows that the refrigerating chamber can be humidified by adding a few grams of water vapor into the refrigerating chamber; assume 1m at 5 deg.C3In the environment, if the relative humidity is desired to be 70%, only the air is needed5.09g of water vapor is added in the reaction kettle. In a natural state of the air-cooled refrigerator, sufficient water vapor cannot be supplied to the refrigerating chamber 1 through gaps such as a door seal and a rotating beam. By utilizing the refrigeration characteristics of the single-system air-cooled refrigerator, namely refrigeration stop of the refrigerating chamber and refrigeration of the freezing chamber, when the refrigerating chamber is in a negative pressure state, high-humidity steam above the water pan 44 is sucked into the refrigerating chamber 1 through a natural convection method, and moisture supplement is completed in a short time, so that the average value of the relative humidity in the single-system air-cooled refrigerator is increased from 20 percent to more than 60 percent, the level of the double-system refrigerator is achieved, and the fresh-keeping effect of fruits and vegetables is greatly improved.
However, the high-humidity air is directly supplied into the refrigerating compartment 1 via the air supply duct 51, the air outlet duct 52, and the air inlet duct 53, which causes two problems: firstly, the power consumption of the refrigerator is increased, and under the extremely high temperature and high humidity environment, condensation may occur on the inner container, the air duct and the shelf of the refrigerating chamber near the air pipe 51, the air outlet pipe 52 and the air inlet pipe 53. This is caused by excess air rich in high temperature and high humidity in the air entering the box; this condition disappears at low temperature and low humidity and can lead to excessive humidification.
In order to coordinate the reliability of the humidifying device when the humidifying device is used in low-temperature low-humidity and high-temperature high-humidity environments, the humidifying device can not excessively humidify when the humidifying device is used in extreme environments; the invention provides a filter element for a refrigerator air conditioning and humidifying device.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-9, the invention is a filter element for a refrigerator air conditioning and humidifying device, the air conditioning and humidifying device includes an air pipe 51, an air outlet pipe 52 and an air inlet pipe 53, the air outlet pipe 52 is inclined upwards, characterized in that the filter element is a streamline pipe with good heat conductivity; the filter cartridge includes a filter tube 61 and a filter nozzle 62; the filter element is matched and arranged on the inner wall of the air outlet pipe 52; the filter nozzle 62 is a tapered flow nozzle.
Wherein, the filter element is made of one or more of aluminum, aluminum alloy, steel, copper and copper alloy; the filter tube 61 is a reducing circular tube or a cylindrical tube; the filter nozzle 62 is a cylindrical nozzle or a conical convergent nozzle or a conical divergent nozzle or a streamline round nozzle; the filter nozzle 62 can be either an inner nozzle or an outer nozzle; the length range of the filter element is 0.1mm-600 mm; the thickness range of the filter element is 0.1mm-20 mm; the length of the filter tube nozzle 62 is 3-4 times of the minimum inner diameter of the filter tube nozzle 62; in fact, the length of the filter element can be adjusted according to the length of the air outlet pipe 52, and the high-temperature and high-humidity air flow sucked from the outside is rapidly cooled by the material on the surface of the air outlet pipe 52, so that the condensation phenomenon can occur, and the air flow is changed from a gas state to a liquid state; the higher the temperature and humidity of the external environment, the better the filtering effect;
in addition, the filter tube nozzle 62 type accords with the design of the fluid mechanics nozzle outflow, although the inner diameter of the filter tube nozzle 62 is far smaller than the outer diameter of the filter element, the flow shrinks, the flow is separated from the tube wall at the inlet of the filter tube nozzle 62 to generate flow separation to form an annular backflow area, the pressure in the backflow area is lower than that at the tube nozzle, an annular vacuum area is formed at the shrinking section, and the existence of the vacuum area generates a suction effect on the gas in the filter tube 61, so that the overflow capacity of the filter tube 61 is improved, the flow loss is greatly reduced, and the total amount of the water vapor entering the refrigerating chamber 1 is ensured; meanwhile, the inlet of the filter tube nozzle 62 reduces the airflow outflow area;
in order to avoid the hot air from directly falling to the surface of the inner container of the refrigerating chamber 1, the filter pipe nozzle 62 is designed to be eccentric, so that the distance between the filter pipe nozzle 62 and the nearest inner container is lengthened, and the risk of condensation of the inner container is reduced; the filter core joint is in outlet duct 52 inner wall, and outlet duct 52 inner wall has certain thickness, and this thickness plays certain heat preservation effect, prevents that the inside high temperature of outlet duct 52, and the outside low temperature arouses the condensation phenomenon.
Specifically, the material with good heat conductivity in a certain length can quickly absorb the cold energy in the refrigerating chamber to enable the refrigerating chamber to be in a low-temperature state; when the hot and humid air passes through the surface of the metal material, the temperature is reduced and the air is condensed along the way, the hot and humid air sucked from the outside is pre-cooled, and the redundant moisture in the air is filtered. When the humidifying device of the air-cooled refrigerator is used in a high-temperature high-humidity environment, the power consumption can be kept low or even ignored, only the required steam is sent into the refrigerating chamber, and the relative humidity in the refrigerating chamber is greatly improved. The filter element outlet is designed into a pipeline nozzle structure, the fluid mechanical nozzle outflow principle is applied, the nozzle structure can enable passing fluid to be pressurized and decelerated, the total gas flow is not reduced, but the diffusion area is greatly reduced, and the condensation risk of the inner container, the shelf, the fan cover and other parts near the inner pipeline of the refrigerating chamber is greatly reduced.
