In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

in the related art, a fan is arranged at the bottom of a refrigerator drawer to improve the air flowability around the drawer, but the fan is started according to a program, and because the height of the fan is lower, the condensation falls under the action of gravity when the fan is not started, and the risk of condensation and icing also exists in the fan.

It should be noted that the information disclosed in the foregoing background section is only for enhancing understanding of the background of the present application and thus may include information that does not form the prior art that is already known to those of ordinary skill in the art.

The refrigerating equipment is mainly used for cabin air conditioning of food refrigeration of crews, refrigeration of various cargoes and summer days. Among them, the refrigerator has been widely used as an electric appliance for low-temperature fresh-keeping storage in homes, offices or super-commercial venues. In order to enhance the practicability of the refrigerator, the inner part of the existing refrigerator is provided with a temperature changing chamber. The temperature range of the temperature changing chamber of the refrigerator is generally-1 ℃ to 7 ℃, and the refrigerator can also be directly set to be used as a freezing chamber at-18 ℃. The food is stored at the temperature of-1 ℃ to 7 ℃, can be thawed slightly, does not need to be thawed additionally after being taken out, and saves the time for melting the food.

For a single-system refrigerator, if the right side of the refrigerator is a temperature changing chamber, hot air in the refrigerator evaporator can flow back into the left side of the temperature changing chamber drawer through the temperature changing return air channel when defrosting due to the fact that the temperature changing return air channel is close to the temperature changing drawer, and hot air is gathered at the temperature after defrosting due to the fact that a top-sealed space is formed between a temperature changing drawer slideway and a temperature changing liner and between the temperature changing drawer and the temperature changing drawer, and excessive water vapor can generate condensation on the side face of the temperature changing drawer due to the fact that a large amount of moisture is contained in hot vapor after defrosting. The air temperature here can reach above 0 c due to the higher defrosting temperature. When refrigeration is carried out, the temperature at the position is rapidly reduced, so that water vapor in the air is rapidly separated out and is condensed and frozen on the side surfaces of the drawer and the inner container, and the user experience is affected.

In the related art, a fan is arranged at the bottom of a drawer of the refrigerator, so that air around the drawer flows, the air fluidity around the drawer is improved, and the ventilation dead angle of the air around the drawer is reduced. In the related art, a fan is arranged at the bottom of a refrigerator drawer to improve the air flowability around the drawer, but the fan is started according to a program, and because the height of the fan is lower, the condensation falls under the action of gravity when the fan is not started, and the risk of condensation and icing also exists in the fan.

The embodiment of the disclosure discloses refrigeration equipment, which increases the air outlet towards the side part of the temperature changing liner 20, which is close to the freezing liner 10, on the basis of refrigeration air outlet by extending the condensation-preventing air duct 50 at the first position of the temperature changing air duct 40, so that the air flow between the temperature changing sliding rail 21 and the temperature changing liner 20 and the temperature changing drawer 22 is blown out, and condensation is prevented from freezing.

Referring to fig. 1-5, embodiments of the present disclosure provide a refrigeration apparatus including a housing 70, a refrigeration liner 10, and a temperature change liner 20. The housing 70 includes a back plate. The freezing liner 10 is arranged in the outer shell 70, and the back wall of the freezing liner 10 is provided with an evaporator 30. The temperature changing liner 20 is disposed within the housing 70 and horizontally juxtaposed with the refrigeration liner 10. Wherein, a temperature-changing air duct 40 is arranged between the back plate and the freezing inner container 10 and between the back plate and the temperature-changing inner container 20, one end of the temperature-changing air duct 40 is communicated with the evaporator 30 of the freezing inner container 10, and the other end is communicated with the temperature-changing inner container 20. The first position of the temperature changing air duct 40 extends towards one side of the temperature changing inner container 20, which is close to the freezing inner container 10, and the anti-condensation air duct 50 is arranged at an included angle with the air outlet of the temperature changing air duct 40.

The refrigeration device includes a housing 70, a refrigeration liner 10, and a temperature change liner 20. The freezing inner container 10 forms a freezing storage space, the temperature inside the temperature changing inner container 20 is adjustable, and a variable temperature storage space is formed. The refrigeration liner 10 and the temperature-changing liner 20 share the same evaporator 30, and the refrigeration system of the refrigeration equipment is simple and reliable. A temperature-changing air duct 40 is arranged between the back plate of the shell 70 and the freezing inner container 10 and the temperature-changing inner container 20, one end of the temperature-changing air duct 40 is communicated with the evaporator 30 of the freezing inner container 10, and the other end is communicated with the temperature-changing inner container 20. The temperature-varying air duct 40 can enable the refrigerating air at the evaporator 30 of the freezing inner container 10 to flow to the temperature-varying inner container 20 so as to refrigerate the temperature-varying inner container 20, and a single refrigerating system structure of refrigerating equipment is realized. Further, the anti-condensation air duct 50 is extended and increased towards the freezing inner container 10 at the first position of the temperature changing air duct 40, the anti-condensation air duct 50 faces the side, close to the freezing inner container 10, of the temperature changing inner container 20, and air outlet blowing to the side, close to the freezing inner container 10, of the temperature changing inner container 20 is increased, and further the problem that freezing is generated after condensation on the side is accumulated is prevented.

It should be noted that, the freezing inner container 10 and the temperature changing inner container 20 are horizontally arranged in parallel, and may be in a form that the freezing inner container 10 is at the left and the temperature changing inner container 20 is at the right, or may be in a form that the freezing inner container 10 is at the right and the temperature changing inner container 20 is at the left. Fig. 1 to 5 illustrate and explain the relative positional relationship of the freezing cylinder 10 on the left and the temperature changing cylinder 20 on the right.

In some alternative embodiments, the anti-condensation duct 50 air outlet is angled at greater than or equal to 20 ° and less than or equal to 90 ° from the temperature swing duct 40 air outlet.

As shown in fig. 2 and 3, the air outlet of the anti-condensation air duct 50 and the air outlet of the variable-temperature air duct 40 form an included angle alpha which is more than or equal to 20 degrees and less than or equal to 90 degrees. The arrangement is such that the outlet air of the anti-condensation air duct 50 flows to the space inside the temperature changing liner 20 close to the freezing liner 10, namely the space between the left side wall of the temperature changing drawer 22 and the left side wall of the temperature changing liner 20 in the figure. By adding the anti-condensation channel, the air outlet of the anti-condensation air duct 50 can blow out the air between the left side wall of the temperature changing drawer 22 and the left side wall of the temperature changing liner 20 when the temperature changing liner 20 is refrigerated, so that condensation is prevented from gathering in the space. Particularly, after defrosting the freezing liner 10, part of the warm air overflows to the inner space of the temperature changing liner 20, which is close to the freezing liner 10, through the temperature changing air return port 61, and the warm air can be blown out by the air outlet of the anti-condensation air duct 50, so that the warm air is prevented from being cooled, condensed and frozen. Specifically, the included angle between the air outlet of the condensation prevention air duct 50 and the air outlet of the temperature changing air duct 40 may be 20 °, 30 °, 40 °, 50 °, 60 °, 70 °, 80 ° or 90 °. The arrow in fig. 3 shows the direction of the air out.

In some alternative embodiments, temperature change air channel 40 extends to temperature change inner container 20 to form temperature change air outlet 41, and anti-condensation air channel 50 extends to temperature change inner container 20 to form anti-condensation air outlet 51.

The temperature changing air duct 40 extends to the temperature changing liner 20 to form a temperature changing air outlet 41, and the temperature changing air outlet 41 is used for discharging air to the temperature changing drawer 22 so as to reduce the temperature in the temperature changing drawer 22. The condensation preventing air duct 50 extends to the temperature changing liner 20 to form a condensation preventing air outlet 51, and the condensation preventing air outlet 51 is used for discharging air to a gap between the side wall of the temperature changing drawer 22 and the side wall of the temperature changing liner 20 so as to prevent condensation from gathering and icing at the position. There are also various arrangements of the relative positions of the temperature varying air outlet 41 and the condensation preventing air outlet 51 according to the included angle between the air outlet of the condensation preventing air duct 50 and the air outlet of the temperature varying air duct 40. As shown in fig. 2, the included angle between the air outlet of the anti-condensation air duct 50 and the air outlet of the variable temperature air duct 40 is smaller, the variable temperature air outlet 41 and the anti-condensation air outlet 51 are positioned on the same horizontal variable temperature air duct 40 wall surface, and the anti-condensation air outlet 51 is positioned on the left side of the variable temperature air outlet 41. As shown in fig. 3, the included angle between the air outlet of the anti-condensation air duct 50 and the air outlet of the variable temperature air duct 40 is larger, the variable temperature air outlet 41 and the anti-condensation air outlet 51 are positioned on different wall surfaces of the variable temperature air duct 40, and the anti-condensation air outlet 51 is positioned on the upper left side of the variable temperature air outlet 41.

In some alternative embodiments, the temperature changing liner 20 is provided with a temperature changing slide rail 21 on the inner side wall, and the temperature changing slide rail 21 is used for sliding the drawer in the temperature changing liner 20 to be pulled out or retracted. Wherein, the top end of the anti-condensation air outlet 51 is higher than the temperature changing slide rail 21 in the vertical direction, and the bottom end is lower than the temperature changing slide rail 21.

The temperature changing slide rail 21 enables the temperature changing drawer 22 to pull out or push in the temperature changing liner 20 more quickly and conveniently. The temperature changing slide rail 21 is arranged on the inner side wall of the temperature changing inner container 20 and is positioned between the inner side wall of the temperature changing inner container 20 and the side wall of the temperature changing drawer 22. The temperature-changing slide rail 21 is usually of metal, when the air in the space where the temperature-changing slide rail 21 is located is condensed, the condensed dew is easy to fall onto the temperature-changing slide rail 21, and further the condensed dew is frozen on the temperature-changing slide rail 21 along with the temperature reduction. Therefore, the top end of the anti-condensation exposing air opening 51 in the vertical direction needs to be higher than the temperature changing slide rail 21, and the bottom end is lower than the temperature changing slide rail 21, i.e. the temperature changing slide rail 21 is located in the air outlet range of the anti-condensation exposing air opening 51. Thus, the air in the space where the temperature changing slide rail 21 is positioned can be timely flowed, and condensation or icing is prevented.

In some alternative embodiments, the refrigeration equipment is further provided with a temperature-changing return air duct 60, one end of the temperature-changing return air duct 60 is communicated with the evaporator 30 of the refrigeration liner 10, and the other end is communicated with the temperature-changing liner 20. Wherein, the temperature-changing return air duct 60 extends to the side wall of the temperature-changing liner 20 near the side of the freezing liner 10 to form a temperature-changing return air port 61.

The refrigeration equipment is also provided with a variable-temperature return air duct 60, and the variable-temperature return air duct 60 has the function of enabling the outlet air of the variable-temperature air duct 40 to exchange heat and then flow back to the evaporator 30 of the refrigeration liner 10 for heat exchange and recycling. In order to improve the air circulation efficiency of the variable temperature liner 20, the variable temperature return air duct 60 extends to the side wall of the variable temperature liner 20, which is close to one side of the freezing liner 10, to form a variable temperature return air opening 61, and the distance between the variable temperature air outlet 41 and the variable temperature return air opening 61 is shortened.

In some alternative embodiments, the top height of the temperature swing return air port 61 is less than the top height of the anti-condensation exposure air port 51.

The top end height of the variable temperature return air inlet 61 is smaller than the top end height of the anti-condensation exposing air inlet 51, so that the air outlet of the anti-condensation exposing air inlet 51 can push the air at the side part of the variable temperature liner 20 to fall and discharge to the freezing liner 10, and particularly the condensation weight of warm air overflowing by defrosting of the freezing liner 10 is increased when contacting with refrigeration air outlet.

In some alternative embodiments, the top end height of the temperature swing return air inlet 61 is less than the bottom end height of the anti-condensation exposure air inlet 51.

Similarly, the top end height of the temperature changing air return opening 61 can be set smaller than the bottom end height of the anti-condensation exposing air opening 51, so that the air outlet of the anti-condensation exposing air opening 51 can further facilitate the side air of the temperature changing liner 20 to fall and be discharged to the freezing liner 10.

In some alternative embodiments, the refrigeration appliance also includes a temperature swing drawer 22. A temperature change drawer 22 is disposed within the temperature change liner 20 for zoned storage of items. The outer surface of the side wall of the temperature changing drawer 22 is provided with a sliding part 221, and the sliding part 221 is used for sliding in the temperature changing sliding rail 21 to drive the temperature changing drawer 22 to be pulled out or retracted.

The temperature changing drawer 22 is disposed in the temperature changing liner 20, and the temperature changing drawer 22 can divide the storage space in the temperature changing liner 20 into a plurality of sub storage partitions, so that the user can store the storage in a classified and relatively independent manner. The outer surface of the side wall of the temperature changing drawer 22 is provided with a sliding piece 221, the inner side wall of the temperature changing liner 20 is provided with a temperature changing sliding rail 21, and when the temperature changing drawer 22 pulls out or pushes in the temperature changing liner 20, the sliding piece 221 slides in the temperature changing sliding rail 21.

In some alternative embodiments, temperature change drawer 22 has anti-condensation holes 222 formed in a side wall thereof adjacent to refrigeration liner 10.

As shown in fig. 5, the side wall of the temperature changing drawer 22, which is close to the freezing inner container 10, is provided with a condensation preventing hole 222, when the condensation preventing air duct 50 is out, the air at the side part of the temperature changing inner container 20 can be pushed to flow into the drawer, and then the temperature is reduced by refrigeration under the action of the temperature changing air duct 40. In some alternative embodiments, the number of anti-condensation holes 222 is a plurality.

In some alternative embodiments, the side wall of temperature change drawer 22 remote from refrigeration liner 10 is provided with a circulating air hole.

The side wall of the temperature changing drawer 22 far away from the freezing inner container 10 is provided with a circulating air hole, namely, the side wall opposite to the side wall provided with the condensation preventing hole 222 is provided with a circulating air hole, and the space of the temperature changing drawer 22 and the inner walls of the two sides of the temperature changing inner container 20 form an open flow path space through the cooperation of the condensation preventing hole 222 and the circulating air hole, so that the generation and aggregation of condensation are reduced.
