The air-cooled refrigerator is easy to cause the too low humidity of the freezing compartment of the refrigerator due to the direct blowing of the air supply, and especially when cold air is directly blown towards food materials in the freezing compartment, the moisture loss of the food materials is easy to accelerate, especially the water loss on the surface of the food materials is serious, the dry consumption is serious, and the oxidation is aggravated. In order to solve the problem of nutrition loss caused by too fast water loss, some products make the drawer airtight, so that external cold air cannot take away the water released by fruits and vegetables in the drawer, and the drawer can be kept in a high-humidity state for a long time. However, such a closed drawer cannot be cooled down quickly, and has no humidity adjusting function.

Referring to fig. 1, the refrigerator according to the embodiment of the present utility model includes a cabinet 101, and a temperature changing chamber 102 is provided in the cabinet 101. The refrigerator further includes a first container 103 and a second container 104, both the first container 103 and the second container 104 are located in the variable temperature chamber 102, and the first container 103 is located above the second container 104.

Referring to fig. 1, it will be appreciated that the first container 103 is configured as an upper slide tray, i.e., the first container 103 has a first opening 105 at the top thereof, and the second container 104 is configured as a lower drawer, i.e., the second container 104 has a second opening 106 at the top thereof. In other words, the first container 103 and the second container 104 may be combined into a temperature changing drawer, the temperature changing drawer includes an upper sliding tray and a lower drawer, the upper sliding tray is disposed on the upper portion of the lower drawer, after the lower drawer is pulled out, a user pulls out or pushes in the upper sliding tray to realize front-back sliding, food in the upper sliding tray or the lower drawer can be selectively taken out, when the upper sliding tray is completely overlapped on the upper portion of the lower drawer, the lower drawer forms a relatively airtight space, a gap between the second container 104 and the first container 103 ranges from 1mm to 5mm, and the temperature changing drawer has a good moisturizing effect on bare food materials (such as food materials without wrapping a freshness preservation bag), so that the internal humidity of the second container 104 can be kept at a level of 90% -95%. The gap may facilitate the sliding of the second container 104 to facilitate the drawing or pushing action of the second container 104. And when cool air is introduced into the second container 104, the air flow entering the second container 104 can flow out, and a certain pressure is maintained.

Referring to fig. 1 and 2, it can be appreciated that the second container 104 is provided with a drawer plate 107, and the drawer plate 107 is located at the front end of the second container 104 and extends upward to the front side of the first container 103, so that the drawer plate 107 can close the inlet of the variable temperature chamber 102 when the first container 103 and the second container 104 are in the closed position. Compared with the scheme of closing the upper half of the inlet of the variable temperature chamber 102 with the front end of the first container 103 and closing the lower half of the inlet of the variable temperature chamber 102 with the front end of the second container 104, the drawer plate 107 of the second container 104 closes the whole inlet of the variable temperature chamber 102, so that the gap between the first container 103 and the second container 104 can be reduced, the sealing property can be improved, and the leakage of cold air can be reduced.

Referring to fig. 2, it may be understood that the refrigerator further includes a cover 201, where the cover 201 is disposed at the first opening 105, so that the first container 103 forms a relatively closed space, for example, a gap between the cover 201 and the first container 103 ranges from 1mm to 5mm, and the existence of the gap may facilitate sliding of the first container 103, so as to smoothly perform the drawing-out or pushing-in operation of the first container 103. Referring to fig. 3, the cover 201 is provided with a plurality of ventilation micro-holes 301, and the ventilation micro-holes 301 are configured to allow air to circulate inside and outside the first container 103.

It will be appreciated that in some embodiments, the open area of all of the ventilation apertures 301 may be in the range of 20% to 22% of the area of the cover 201, and may maintain the humidity within the first container 103 at a level of 80% -90%. When the open area is smaller than 20%, the cold air is not beneficial to entering the first container 103 for heat exchange, so that the cooling rate is slow, and the cooling requirement cannot be met. When the open area is larger than 22%, the moisture retention in the first container 103 is not facilitated, and the humidity is less than 80%.

Referring to fig. 3, it can be appreciated that in some embodiments, the gas permeable micro-pores 301 have a pore size D in the range of 3.7mm to 3.9mm. When D is less than 3.7mm, it is difficult to achieve ventilation inside and outside the first container 103. When D is greater than 3.9mm, it is difficult to maintain a high humidity state inside the first container 103.

Referring to fig. 3, it is understood that in some embodiments, the plurality of ventilation micro-holes 301 are divided into a plurality of rows, and the distance between two adjacent ventilation micro-holes 301 in each row is L1, and the value of L1 may be selected to be 8mm, 10mm, 12mm, etc., and will be described below with the value of L1 being 10 mm.

Referring to FIG. 3, it will be appreciated that in some embodiments, the row spacing between adjacent rows is L2, and the values of L2 may be selected to be 3mm, 4mm, 5mm, 6mm, 8mm, etc., and will be described below as L2 having a value of 5 mm.

Referring to fig. 3, it will be understood that in some embodiments, two adjacent rows of ventilation micropores 301 are arranged in a staggered manner, that is, there is a group of ventilation micropores 301, where the group of ventilation micropores 301 has 4 ventilation micropores 301 that form a square, the size of the square is 10mm by 10mm, and a ventilation micropore 301 is further formed in the middle of the 4 ventilation micropores 301, and the ventilation micropores 301 are located at the diagonal intersection points of the square. This allows for efficient use of space and a more uniform distribution of the air flow.

Referring to fig. 2, it can be understood that the second container 104 is provided with a second air vent 207, and the second air vent 207 is communicated with the inside and the outside of the second container 104, so that cold air generated by a refrigeration system in the refrigerator can enter the inside of the second container 104, thereby realizing rapid cooling, and also storing some articles with lower requirements on humidity.

It should be noted that, in other embodiments, the refrigerator compartment 214 is provided in the case 101, and the first container 103 and the second container 104 may also be both disposed in the refrigerator compartment 214, so that the airflows of the first container 103 and the second container 104 may be adjusted correspondingly according to different temperature and humidity requirements.

Referring to fig. 2, it can be appreciated that the refrigerator further includes a duct assembly for delivering cool air to the first and second containers 103 and 104. For example, the air duct assembly includes an air duct cover 203, an air supply damper 202 is disposed at the bottom of the air duct cover 203, the air supply damper 202 is connected with a freezing chamber 204 and a temperature changing chamber 102, the function is to make the freezing chamber 204 convey cold air to the temperature changing chamber 102 to control temperature, an air duct foam 205 is disposed in the temperature changing air duct cover 203, a channel guiding air flow direction is formed in the air duct foam 205, and the air duct assembly has different working states by controlling the air flow direction, so that the refrigerator enters different working modes.

Referring to fig. 2 and 4, it will be appreciated that the air duct assembly has a first state, the air duct assembly has a first air opening 206, the first air opening 206 is located at the rear side of the first container 103, the air flow blows out from the first air opening 206 and flows over the cover 201, then flows down the front side of the first container 103, and finally flows back from the bottom of the second container 104 to the return air opening 401, and no air flow is blown directly into the second container 104 during the whole process, i.e. when the air duct assembly is in the first state, the air flow blows toward the cover 201 and avoids the second air opening 207. The cool air flowing through the upper portion of the cover 201 is permeated into the inside of the first container 103 through the air-permeable micro holes 301, so that the cooling rate can be increased. However, only part of the water vapor can escape to the outside of the cover plate 201 through the ventilation micropores 301, so as to help to maintain the internal humidity of the first container 103, and meanwhile, part of the water vapor escapes to the outside of the cover plate 201 through the ventilation micropores 301, so that the first container 103 can be prevented from mildewing due to overhigh humidity, and the humidity requirement of 85% -95% of fruit food materials can be met. Because the cold air does not directly enter the first container 103 and the second container 104, the cold air cannot easily take away the moisture in the first container 103 and the second container 104, the first container 103 and the cover plate 201 cooperate to form a relatively closed space, the first container 103 and the second container 104 cooperate to form a relatively closed space, and the high humidity in the first container 103 and the second container 104 is ensured, namely, high moisture retention is realized.

Referring to fig. 2 and 5, it will be appreciated that the air duct assembly has a second state, the air duct assembly has a third air port 208, the third air port 208 is located at the rear side of the second container 104 and corresponds to the position of the second opening 106, a portion of the air flow is blown out of the third air port 208 and into the interior of the second container 104 through the second opening 106, then flows down the front side of the second container 104, and finally flows back to the return air port 401 from the bottom of the second container 104. In addition, a portion of the airflow is blown out from the first tuyere 206 and flows along the upper side of the cover plate 201, then flows down along the front side of the first container 103, and finally flows back to the return air opening 401 from the bottom of the second container 104. I.e. when the air duct assembly is in the second state, the air flow blows towards the second air vent 207 and the cover 201. Because cold air slowly enters the first container 103 and is directly blown into the second container 104, the first container 103 and the second container 104 can be enabled to quickly cool and store temperature, and the upper layer and the lower layer realize the simultaneous air supply. In addition, the water loss in the first container 103 is small, the water loss in the second container 104 is large, and the distribution pattern of the upper layer high humidity and the lower layer low humidity is presented, thereby realizing the dry and wet separation storage.

Therefore, the air duct assembly is utilized to control the air flow direction, and the third air port 208 is opened or closed, so that the humidity and the temperature in the second container 104 can be adjusted, and the temperature in the first container 103 can be also adjusted, thereby meeting the storage condition requirements of different food materials.

Referring to fig. 1 and 2, it can be understood that the front portion of the first container 103 is provided with a moisture-retaining film 108, and the moisture-retaining film 108 is used for adjusting the humidity of the second container 104, and the moisture-retaining film 108 has moisture-retaining and moisture-permeable effects, and when the humidity of the second container 104 is too high, for example, the humidity is greater than 95%, the moisture-retaining film 108 is moisture-permeable to the outside of the first container 103, reducing the humidity inside the second container 104. When the humidity of the second container 104 is low, for example, the humidity is less than 90%, the moisturizing film 108 plays a moisturizing role, and the humidity requirement of 90% -95% of vegetable food materials is met.

Referring to fig. 2, it can be understood that the front portion of the first container 103 is provided with a front plate 209 and a bending plate 210, the bending plate 210 is formed to be bent downward from an upper end of the front plate 209, a humidity adjusting space 211 is provided between the front plate 209 and the bending plate 210, and a lower portion of the humidity adjusting space 211 is opened so as to communicate with the second opening 106. The front plate 209 is used for isolating the inner space of the first container 103 from the humidity adjusting space 211, and the humidity maintaining film 108 is mounted on the bent plate 210, so that the installation and the replacement of a user are convenient.

Referring to fig. 6, it can be appreciated that in some embodiments, a channel for guiding the air flow direction is formed in the air duct foam 205, the channel has a first air duct 601 and a second air duct 602, the first air duct 601 and the second air duct 602 are independent, the air supply air door 202 is a double air door, and the air supply air door 202 is used to open one of the first air duct 601 and the second air duct 602, so as to realize the first state or the second state of the air duct assembly. The air supply damper 202 is located between the freezing chamber 204 and the temperature changing chamber 102, and functions to enable the freezing chamber 204 to convey cold air to the temperature changing chamber 102 through the freezing air duct 603 for temperature control.

As shown in fig. 2 and 6, the first container 103 is provided with a first ventilation opening 212, and the first ventilation opening 212 is communicated with the inside and the outside of the first container 103, so that cold air generated by a refrigeration system in the refrigerator enters the inside of the first container 103, and rapid cooling is realized. The air outlet end of the first air duct 601 is provided with a first air opening 206, the first air opening 206 faces the upper portion of the cover plate 201, the air outlet end of the second air duct 602 is provided with a second air opening 213 and a third air opening 208, the second air opening 213 faces the first air opening 212, and the third air opening 208 faces the second air opening 207.

When the air duct assembly is in the first state, the air supply damper 202 opens the first air duct 601, cold air conveyed by the freezing air duct 603 is conveyed to the upper portion of the cover plate 201 through the first air opening 206, and the cold air surrounds the first container 103 and the second container 104 and returns to the freezing chamber 204 through the air return opening 401. Because the cold air does not directly enter the first container 103 and the second container 104, the cold air is not easy to take away the moisture in the first container 103 and the second container 104, and the upper sliding tray and the lower drawer are ensured to be highly moisturized.

When the air duct assembly is in the second state, the air supply damper 202 opens the second air duct 602, cold air conveyed by the freezing air duct 603 is conveyed to the inside of the first container 103 through the second air port 213 and conveyed to the inside of the second container 104 through the third air port 208, and the cold air is directly blown into the inside of the first container 103 and the second container 104, so that the first container 103 and the second container 104 can be quickly cooled, and the performance requirements of heat storage, freezing capacity and the like are met.

It should be noted that, in other embodiments, when the air duct assembly is in the second state, the air supply damper 202 opens the second air duct 602, and may close the first air duct 601, and at this time, the air flow may only flow into the first container 103 and the second container 104, and not flow to the upper portion of the cover 201.

With the recent rise of fresh electric suppliers, people gradually change the storage space of meat and fresh food materials from long-term storage to short-term storage, and in recent years, the wide-range temperature changing function is flexibly switched between refrigeration and freezing due to the large storage space, so that the wide-range temperature changing device is popular with users, the users can flexibly adjust the proper storage function according to actual storage needs, for example, when fruits and vegetables are stored, the temperature changing drawer can be adjusted to a refrigeration gear (0 ℃ to 5 ℃), for example, when meat is stored, the temperature changing drawer can be adjusted to a soft freezing/freezing gear (-1 ℃ or below), for example, -18 ℃, -24 ℃, -30 ℃, -40 ℃, -60 ℃).

Referring to fig. 7, it can be understood that, with the solution according to the embodiment of the present utility model, when the user sets the temperature-changing chamber 102 to the refrigeration level, that is, when the temperature of the temperature-changing chamber 102 is between 0 ℃ and 5 ℃, the air supply damper 202 opens the first air duct 601, closes the second air duct 602, the first air port 206 can supply air, and the second air port 213 and the third air port 208 cannot supply air. The cold air does not directly enter the first container 103 and the second container 104, so that the water of food materials is prevented from being taken away, and the full-space high-humidity function is realized.

Referring to fig. 4 and 7, it can be understood that cold air flows upward from the bottom of the second container 104, surrounds the first container 103 and the second container 104 for one week, and returns to the freezing chamber 204 through the return air inlet 401. Therefore, the temperature of the internal food materials can be reduced through heat exchange of the outer side wall, and the environment of low-temperature fresh-keeping is improved.

Referring to fig. 8, it can be understood that when the user sets the variable temperature chamber 102 to a freezing range, that is, when the temperature of the variable temperature chamber 102 is below-1 ℃, the air supply damper 202 opens the first air duct 601 and the second air duct 602, and the first air port 206, the second air port 213, and the third air port 208 can supply air. Cold air directly enters the first container 103 and the second container 104 and is also conveyed to the upper part of the cover plate 201, so that the first container 103 and the second container 104 can be guaranteed to be rapidly cooled, the cooling speed of food materials is accelerated, the temperature of the food materials is reduced to a set temperature, and the fresh-keeping effect is improved. It can be appreciated that, because the set temperature of the freezing range is low, if the cooling speed of the food material is slow, the temperature of the food material may not be reduced to the set temperature in a short time, which eventually results in poor fresh-keeping effect.

In other embodiments, when the user sets the temperature changing chamber 102 to the refrigerating level, the air supply damper 202 opens the first air duct 601 and the second air duct 602, and the first air port 206, the second air port 213, and the third air port 208 can supply air.

It will be appreciated that other embodiments may be extended from the above embodiment, in which the temperature change chamber 102 is capable of operating in a first gear and a second gear, the temperature of the temperature change chamber 102 in the first gear being higher than the temperature of the temperature change chamber 102 in the second gear. When the temperature-changing chamber 102 is set to be in the first gear, and the current temperature of the temperature-changing chamber 102 is greater than the set temperature of the first gear, the air duct assembly is opened to realize ventilation, and the air duct assembly is in the first state to realize full-space high humidity. When the temperature-changing chamber 102 is set to be in the second gear, and the current temperature of the temperature-changing chamber 102 is greater than the set temperature of the second gear, the air duct assembly is opened to realize ventilation, and the air duct assembly is in the second state, and the first container 103 realizes constant temperature and high humidity.

It should be noted that, when the temperature changing chamber 102 is in the first gear or the second gear, that is, when the current temperature of the temperature changing chamber 102 reaches the set temperature, the air duct assembly does not ventilate at this time, and the air duct assembly can be in the first state or the second state.

In summary, the air-permeable micro-pores 301 function: ① When the refrigerator is switched to a cold storage range, part of water vapor can escape to the outside of the cover plate 201 through the ventilation micropores 301, so that the berry fruits are prevented from mildewing due to the excessively high humidity of the first container 103, and the humidity requirement of 85% -95% of fruit food materials is met; ② When the refrigerating operation is switched to the freezing operation, cold air flowing through the upper part of the cover plate 201 permeates into the first container 103 through the ventilation micropores 301, so that the refrigerating and cooling speed can be increased; ③ When defrosting by freezing, the hot air generated by the heating wire can be prevented from directly entering the first container 103 to impact the temperature of the food, so that the temperature of the food is greatly fluctuated.

Referring to fig. 7, it can be understood that the first air duct 601 and the second air duct 602 are disposed in the left-right direction, and the air inlets of the first air duct 601 and the second air duct 602 correspond to the bottom of the second container 104, so that cold air flows upward from the bottom of the second container 104 to the upper side of the first container 103 and the upper side of the second container 104, and the heat exchange area of the first air duct 601 and the second air duct 602 with the first container 103 and the second container 104 increases, which is advantageous for improving the heat exchange efficiency.

It will be appreciated that in other embodiments, the first air channel 601 and the second air channel 602 may be disposed in an up-down direction.

Referring to fig. 7, it may be understood that the first air duct 601 includes a first air outlet branch 701 and a second air outlet branch 702, and the first air outlet branch 701 and the second air outlet branch 702 are disposed in a left-right direction. The air return port 401 is generally positioned at the left side of the drawing, and the first air duct 601 is positioned at the right side of the drawing, so that a part of air is guided to the right side, and the temperature at the right side can be better pulled down. If the first outlet branch 701 and the second outlet branch 702 are combined, it is possible that the right temperature is too high, because most of the wind flows directly back to the left return air inlet 401. That is, the first air duct 601 is divided into the first air outlet branch 701 and the second air outlet branch 702, and the first air outlet branch 701 and the second air outlet branch 702 are arranged along the left-right direction, so that the uniformity of the temperature distribution can be improved.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
