Description

Technical Field

[0001] The present application relates to the field of refrigeration equipment, and in particular to a refrigerator. Background Art

[0002] Food is stored in the refrigerator's refrigerator compartment. The food will continuously generate heat during the storage process. In addition, the lighting will also generate a certain amount of heat. Therefore, there are heat sources in the refrigerator's refrigerator compartment. These heat sources will affect the temperature and humidity of the refrigerator compartment, and then affect the preservation effect of food.

[0003] The refrigeration cycle of the refrigerator is to provide cooling capacity through the compressor, and after the evaporator exchanges heat, the fan is used to transport the cold air to each room through the air duct. There is a refrigeration air duct in the refrigerator, a freezing air duct in the freezer, and a variable temperature air duct in the variable temperature room. Each room has an air duct for inputting cold air. One end of the air duct outlet is connected to the cold air inlet, and the other end of the air duct outlet is connected to the air supply inlet of the room. In other words, each air duct is an independent space.

[0004] However, due to the presence of a heat source in the refrigerator, when cold air is transported into the refrigerator, the heat source will neutralize the cold air, causing the temperature of the cold air to be higher than the preset temperature that needs to be reached in the refrigerator. Therefore, the refrigeration temperature will be lowered to neutralize the heat source, resulting in high power consumption of the refrigerator. Utility Model Content

DETAILED DESCRIPTION

[0025] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0026] See also Figure 1 , Figure 2 The present application embodiment is a refrigerator, comprising: a box body, a door body 2, and a refrigerator box 3. The box body is provided with a refrigerating chamber 1, and the refrigerating chamber 1 has drawers, shelves, etc. The refrigerating chamber 1 is provided with a plurality of air outlets 21 and reverse air outlets 17. Figure 1 The arrow in the middle is the air outlet 21. Figure 1 The example in FIG. 1 shows four air outlets 21, and the direction of the arrow is the air outlet direction, that is, the air outlet 21 blows air outward; Figure 1 There is only one counter-air outlet 17 in the example, and the air outlet direction of the counter-air outlet 17 is opposite to that of the air outlet 21. The counter-air outlet 17 discharges air inwardly, and the air discharged from the counter-air outlet 17 is high-temperature air generated by food or lighting in the refrigerator compartment 1.

[0027] The refrigeration air duct assembly at least includes a refrigeration air duct 14, which is respectively connected to the air outlet 21 and the reverse air outlet 17. An evaporator is arranged in the refrigeration air duct 14, and the evaporator reduces the temperature inside the refrigerator by absorbing heat. The evaporator is arranged inside the air duct, so that the cold air can be blown to each compartment of the refrigerator by the air duct.

[0028] Illustratively, there is refrigerant in the evaporator. After the refrigerant absorbs heat in the evaporator, it will turn into low-pressure steam. When the low-pressure steam is sucked into the compressor and compressed into high-pressure steam, it is sent to the condenser. In the condenser, the high-pressure steam releases heat, cools the air and forms cold wind. The cold wind is transported to each compartment of the refrigerator through the refrigeration air duct 14 and the air outlet 21.

[0029] The reverse air outlet 17 of the refrigeration air duct 14 forms a positive pressure, and a negative pressure is formed in the refrigeration chamber 1. Through the positive pressure and the negative pressure, the wind in the refrigeration chamber 1 flows to the reverse air outlet 17. The reverse air outlet 17 of the refrigeration air duct 14 can be set at a position where the temperature inside the air duct is relatively low, which will increase the density of the air there and form a certain positive pressure. The temperature in the refrigeration chamber 1 is relatively high, and the air density is relatively low, forming a certain negative pressure. This positive and negative pressure difference will cause the hot air in the room to flow to the reverse air outlet 17 of the air duct.

[0030] Through the pressure difference between the inside and outside of the reverse air outlet 17, the high-temperature air in the refrigerating chamber 1 can be sucked into the reverse air outlet 17, and the high-temperature air enters the refrigerating air duct 14 through the reverse air outlet 17. The high-temperature air is mixed with the cold air provided by the evaporator in advance in the refrigerating air duct 14 to reduce the temperature, and the cold air sent out through the air outlet 21 can directly reach the preset temperature, saving the power consumption of the refrigerator. The high-temperature air in the refrigerating chamber 1 sucked into the reverse air outlet 17 is mixed with the cold air provided by the evaporator in advance in the refrigerating air duct 14 to reduce the temperature, thereby improving the efficiency and increasing the air volume of the air outlet 21.

[0031] In order to increase the amount of high-temperature air in the refrigerating chamber 1 sucked into the reverse air outlet 17, in some embodiments, a booster assembly is provided on the reverse air outlet 17, and the booster assembly includes at least a blower and a booster fan. The booster fan and the blower increase the pressure of the hot air by rotating or compressing, so that the hot air passes through the reverse air outlet 17 at a higher speed and flow rate. A fluid dynamic booster device can also be added, which uses the principle of fluid dynamics to increase the pressure of the hot air by changing the flow direction and speed of the hot air.

[0032] To facilitate adjustment of the air volume of the air outlet 21, in some embodiments, an air volume adjustment lever is provided on the air duct, and the air volume adjustment lever includes an adjustment wheel 13 and an adjustment knob 15. The adjustment wheel 13 is arranged in the refrigeration air duct 14, and the adjustment knob 15 is arranged outside the refrigeration air duct 14. The adjustment wheel 13 is arranged at the connection between the evaporator refrigeration and the refrigeration air duct 14. By rotating the adjustment wheel 13, the air volume of the cold air of the evaporator refrigeration transmitted to the refrigeration air duct 14 can be controlled, so that the air volume of the air outlet 21 can be controlled. The adjustment knob 15 is then arranged outside the refrigeration air duct 14. It can be understood that it can be arranged at a position that can be touched by the user. The user controls the adjustment wheel 13 by rotating the adjustment knob 15, and then controls the air volume of the air outlet 21.

[0033] In some embodiments, the refrigeration duct assembly further includes an air duct cover 12, which is disposed on the refrigeration duct 14 and covers the air volume adjustment rod. The air duct cover 12 can cover the air supply port or the entire refrigeration duct 14 to maintain the stability and uniformity of the air supply.

[0034] See also Figure 3In some embodiments, a guide trough assembly 171 is provided on the reverse air outlet 17. The guide trough assembly 171 includes a mounting plate and a guide plate. The mounting plate is connected to the reverse air outlet 17. A plurality of protrusions are provided on the guide plate. The protrusions are arranged in parallel at intervals. The axis direction of the protrusions is parallel to the flow direction of the hot air in the refrigerating chamber 1. Since the reverse air outlet 17 inhales the high-temperature air in the refrigerating chamber 1, in order to make the inhaled air more uniform, a plurality of protrusions are provided on the surface of the guide plate. The protrusions and the surface of the guide plate form grooves. The high-temperature air flows into the reverse air outlet 17 through the grooves, which can make the air more uniform. Since the direction in which the guide plate is set forms an angle with the reverse air outlet 17, the angle can help the reverse air outlet 17 absorb the high-temperature air of a larger area of ​​the refrigerating chamber 1.

[0035] In addition to using the guide groove assembly 171 to increase the air volume of the inhaled high-temperature air, the air intake volume of the reverse air outlet 17 can also be adjusted according to actual conditions. In some embodiments, an adjustment cover is provided on the reverse air outlet 17, and the adjustment cover movably covers the reverse air outlet 17. The adjustment cover is arranged on the side wall of the reverse air outlet 17, and a slide is provided on the reverse air outlet 17. The user controls the opening size of the reverse air outlet 17 by adjusting the adjustment cover to move on the slide.

[0036] Different foods are placed in the refrigerator 1, for example, vegetables may produce broken leaves or carry soil, etc. That is, the food may carry impurities and remain in the refrigerator 1. In some embodiments, a filter body is provided on the reverse air outlet 17, and an adsorption filter and a dust removal filter are provided on the filter body in sequence, and the cross-sectional shape of the filter body is the same as the cross-sectional shape of the reverse air outlet 17.

[0037] The filter body is installed on the reverse air outlet 17 to further filter and purify the inhaled hot air. The adsorption filter can effectively remove larger particles. Larger particles are easily adsorbed on the filter. The dust filter can remove smaller particles. The dust filter uses finer materials and structures to capture tiny particles and further purify the hot air.

[0038] Among them, if the cross-sectional shape of the reverse air outlet 17 is rectangular, the filter body is a hollow rectangular frame, and the adsorption filter and the dust-proof filter are both hollow rectangles, covering the filter body; if the cross-sectional shape of the reverse air outlet 17 is circular, the filter body is a hollow cylindrical frame, and the adsorption filter and the dust-proof filter are both hollow cylindrical structures.

[0039] In some embodiments, a refrigeration air hood 16 is further included, which is connected to the refrigeration air duct assembly. An air outlet channel and a reverse air outlet channel are provided on the refrigeration air hood 16. The air outlet channel is connected to the air outlet 21, and the reverse air outlet channel is connected to the reverse air outlet 17.

[0040] The air outlet channel inside the refrigeration air hood 16 introduces the cold air from the refrigeration air duct 14 into the refrigeration chamber 1. The connection between the refrigeration air hood 16 and the air duct can better ensure the flow efficiency and uniformity of the cold air.

[0041] In some embodiments, a first temperature sensor is provided at the connection between the refrigerated air duct 14 and the reverse air outlet 17, a second temperature sensor 19 is provided at the connection between the refrigerated air duct 14 and the air outlet 21, and a third temperature sensor is provided in the refrigerated chamber 1, and the first temperature sensor, the second temperature sensor 19 and the third temperature sensor are communicatively connected with each other.

[0042] By setting a first temperature sensor at the reverse air outlet 17, the first temperature sensor can monitor the temperature of the high-temperature air inhaled by the reverse air outlet 17, and the second temperature sensor 19 monitors the air temperature of the evaporator refrigeration. The evaporator can be controlled according to the real-time required temperature in the cold storage room 1 detected by the third temperature sensor and the temperature of the inhaled high-temperature air.

[0043] A first viscose sponge 11, a second viscose sponge 18 and a third viscose sponge 20 are respectively provided at different positions on the refrigeration air duct 14, including on the air duct, at the connection between the evaporator and the air duct, and at the connection between the air duct and the refrigeration air cover 16. The viscose sponge is used for noise reduction and heat preservation of the air duct. The viscose sponge can absorb the noise generated when the air flows in the air duct, thereby reducing the impact of the air duct noise on the surrounding environment. The viscose sponge can prevent heat exchange between the inside and outside of the air duct and keep the temperature inside the air duct stable.

[0044] It can be seen from the above technical scheme that the present application provides a refrigerator, including: a refrigerating chamber 1, a refrigerating air duct assembly, wherein a plurality of air outlets 21 and a reverse air outlet 17 are arranged in the refrigerating chamber 1; the refrigerating air duct assembly at least includes a refrigerating air duct 14, and the refrigerating air duct 14 is respectively connected to the air outlet 21 and the reverse air outlet 17; the reverse air outlet 17 forms a positive pressure, and a negative pressure is formed in the refrigerating chamber 1, and the air in the refrigerating chamber 1 flows into the reverse air outlet 17 through the positive pressure and the negative pressure. Through the pressure difference between the inside and outside of the reverse air outlet 17, the high-temperature air in the refrigerating chamber 1 can be sucked into the reverse air outlet 17, and the high-temperature air enters the refrigerating air duct 14 through the reverse air outlet 17, and the high-temperature air is mixed with the cold air provided by the evaporator in advance in the refrigerating air duct 14 to reduce the temperature, and the cold air sent out through the air outlet 21 can directly reach the preset temperature, thereby saving the power consumption of the refrigerator.
