Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, and particularly to a refrigerator. Background Art

[0002] With the rise of fresh food e-commerce in recent years, people's demand for long-term storage of meat and fresh food ingredients has gradually shifted to short-term storage. In recent years, the wide-range variable temperature function has been favored by users because of its large storage space and flexible switching between refrigeration and freezing. Users can flexibly adjust the appropriate storage function according to actual storage needs. For example, when storing fruits and vegetables, the variable temperature drawer can be adjusted to the refrigeration gear (0°C to 5°C), and when storing meat, it can be adjusted to the soft freezing / freezing gear (below -1°C). As is well known, in addition to temperature, humidity is also one of the important factors affecting the storage of fruits and vegetables. Maintaining a high-humidity environment helps to extend the freshness period of fruits and vegetables. Generally, a humidification module can be set to adjust the humidity in the drawer. However, when the variable temperature drawer switches from the freezing gear to the refrigeration gear, the humidification component is prone to malfunction due to icing. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present invention provides a refrigerator that can adjust the temperature change rate and humidity, and can reduce the impact of icing on the humidification component.

[0054] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0055] In the description of the present invention, it should be understood that with respect to the orientation description, such as the up, down, front, back, left, right, etc., the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0056] In the description of the present invention, the meaning of "several" is one or more, the meaning of "multiple" is two or more, and the understandings such as "greater than", "less than", "exceeding", etc. do not include the present number, and the understandings such as "above", "below", "within", etc. include the present number. If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0057] In the description of the present invention, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0058] Referring to Figure 1 As shown, the refrigerator of the embodiment of the present invention includes a cabinet 101, and a variable temperature compartment 102 is provided inside 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 compartment 102, and the first container 103 is located above the second container 104.

[0059] Referring to Figure 1As shown, it can be understood that the first container 103 is configured as an upper sliding tray, that is, the top of the first container 103 has a first opening 105, and the second container 104 is configured as a lower drawer, that is, the top of the second container 104 has a second opening 106. In other words, the first container 103 and the second container 104 can be combined into a variable-temperature drawer. The variable-temperature drawer includes an upper sliding tray and a lower drawer. The upper sliding tray is arranged above the lower drawer. After the lower drawer is pulled out, the user can pull out or push in the upper sliding tray to achieve forward and backward sliding, and can choose to take out the food in the upper sliding tray or the lower drawer. When the upper sliding tray completely overlaps the upper part of the lower drawer, a relatively airtight space is formed in the lower drawer. The gap between the second container 104 and the first container 103 ranges from 1 mm to 5 mm, which has a good moisture preservation effect on the naked food ingredients (such as food ingredients without a fresh-keeping bag wrapped), and can keep the internal humidity of the second container 104 at the level of 90%-95%. The existence of the gap can facilitate the sliding of the second container 104 to smoothly perform the pulling or pushing action of the second container 104. And when cold air is introduced into the second container 104, it can allow the air flow entering the second container 104 to flow out and maintain a certain pressure.

[0060] It should be noted that the first container 103 and the second container 104 can also be arranged side by side in the left-right direction. Correspondingly, the first opening 105 and the second opening 106 are arranged facing the left-right direction.

[0061] Refer to Figure 1 and Figure 2 As shown, it can be understood that the second container 104 is provided with a drawer board 107. The drawer board 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 when the first container 103 and the second container 104 are in the closed position, the drawer board 107 can close the entrance of the variable-temperature chamber 102. Compared with the scheme of using the front end of the first container 103 to close the upper half of the entrance of the variable-temperature chamber 102, and using the front end of the second container 104 to close the lower half of the entrance of the variable-temperature chamber 102, the drawer board 107 of the second container 104 closes the entire entrance of the variable-temperature chamber 102, which can reduce the gap between the first container 103 and the second container 104, improve the sealing performance, and reduce the leakage of cold air.

[0062] Refer to Figure 2 As shown, it can be understood that the refrigerator further includes a cover plate 201. The cover plate 201 is arranged at the first opening 105 so that the first container 103 forms a relatively airtight space. For example, the gap between the cover plate 201 and the first container 103 ranges from 1 mm to 5 mm. The existence of the gap can facilitate the sliding of the first container 103 to smoothly perform the pulling or pushing action of the first container 103. Refer to Figure 3As shown, the cover plate 201 is provided with a plurality of breathable micropores 301, and the breathable micropores 301 are configured to allow air to flow between the inside and outside of the first container 103.

[0063] It can be understood that in some embodiments, the proportion of the opening area of all the breathable micropores 301 in the area of the cover plate 201 is 20% to 22%, which can maintain the humidity inside the first container 103 at the level of 80% - 90%. When the proportion of the opening area is less than 20%, it is not conducive to the cold air entering the inside of the first container 103 for heat exchange, resulting in a slow cooling rate and not meeting the cooling requirements. When the proportion of the opening area is greater than 22%, it is not conducive to maintaining the humidity inside the first container 103, and the humidity is less than 80%.

[0064] Refer to Figure 3 As shown, it can be understood that in some embodiments, the aperture of the breathable micropore 301 is D, and the size range of D is 3.7 mm to 3.9 mm. When D is less than 3.7 mm, it is difficult to achieve the air circulation between the inside and outside of the first container 103. When D is greater than 3.9 mm, it is difficult to maintain the high-humidity state inside the first container 103.

[0065] Refer to Figure 3 As shown, it can be understood that in some embodiments, the plurality of breathable micropores 301 are divided into multiple rows, and the distance between two adjacent breathable micropores 301 in each row is L1. The value of L1 can be selected as 8 mm, 10 mm, 12 mm, etc. Hereinafter, the value of L1 is taken as 10 mm for illustration.

[0066] Refer to Figure 3 As shown, it can be understood that in some embodiments, the row spacing between two adjacent rows is L2. The value of L2 can be selected as 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, etc. Hereinafter, the value of L2 is taken as 5 mm for illustration.

[0067] Refer to Figure 3 As shown, it can be understood that in some embodiments, the breathable micropores 301 in two adjacent rows are arranged in a staggered manner. That is to say, there is a group of breathable micropores 301, and this group of breathable micropores 301 has 4 breathable micropores 301 forming a square, the size of the square is 10 mm * 10 mm, and there is also a breathable micropore 301 opened in the middle of these 4 breathable micropores 301, and this breathable micropore 301 is located at the intersection of the diagonals of the above square. This can effectively utilize the space and make the air flow distribution more uniform.

[0068] Refer to Figure 2As shown, it can be understood that the second container 104 is provided with a second vent 207. The second vent 207 communicates the interior and exterior of the second container 104, enabling the cold air generated by the refrigeration system in the refrigerator to enter the interior of the second container 104, achieving rapid cooling, and can also store some items with lower humidity requirements.

[0069] It should be noted that in some other embodiments, a refrigerating chamber 214 is provided in the cabinet 101, and the first container 103 and the second container 104 can also be both arranged in the refrigerating chamber 214. According to different temperature and humidity requirements, the airflows of the first container 103 and the second container 104 are correspondingly adjusted.

[0070] Refer to Figure 2 As shown, it can be understood that the refrigerator further includes an air duct assembly for delivering cold air to the first container 103 and the second container 104. For example, the air duct assembly includes an air duct cover 203. A supply air damper 202 is provided at the bottom of the air duct cover 203. The supply air damper 202 connects the freezer compartment 204 and the variable temperature compartment 102, and its function is to allow the freezer compartment 204 to deliver cold air to the variable temperature compartment 102 for temperature control. A duct foam 205 is provided inside the variable temperature air duct cover 203, and a channel for guiding the airflow direction is formed in the duct foam 205. By controlling the airflow direction, the air duct assembly has different working states, and thus the refrigerator enters different working modes.

[0071] Refer to Figure 2 and Figure 4As shown, it can be understood that the air duct assembly has a first state. The air duct assembly has a first air outlet 206, and the first air outlet 206 is located at the rear side of the first container 103. The air flow blows out from the first air outlet 206 and flows above the cover plate 201, then flows downward along the front side of the first container 103, and finally flows back to the return air outlet 401 from the bottom of the second container 104. During the whole process, no air flow directly blows into the interior of the second container 104. That is, when the air duct assembly is in the first state, the air flow blows towards the cover plate 201 and avoids the second ventilation opening 207. The cold air flowing through the upper part of the cover plate 201 seeps into the interior of the first container 103 through the breathable micropores 301, which can improve the cooling speed. However, only part of the water vapor can escape to the outside of the cover plate 201 through the breathable micropores 301, which helps to maintain the internal humidity of the first container 103. At the same time, part of the water vapor escapes to the outside of the cover plate 201 through the breathable micropores 301, which can prevent the berries in the first container 103 from mildewing due to excessive humidity and meet the humidity requirements of 85%-95% for fruit ingredients. Since the cold air does not directly enter the first container 103 and the second container 104, the cold air cannot easily carry away the moisture inside the first container 103 and the second container 104. The first container 103 and the cover plate 201 cooperate to form a relatively airtight space, and the first container 103 and the second container 104 cooperate to form a relatively airtight space, ensuring that the interiors of the first container 103 and the second container 104 maintain a relatively high humidity, that is, high humidity preservation is achieved.

[0072] Referring to Figure 2 and Figure 5 As shown, it can be understood that the air duct assembly has a second state. The air duct assembly has a third air outlet 208, and the third air outlet 208 is located at the rear side of the second container 104 and corresponds to the position of the second open end 106. A part of the air flow blows out from the third air outlet 208 and blows into the interior of the second container 104 from the second open end 106, then flows downward along the front side of the second container 104, and finally flows back to the return air outlet 401 from the bottom of the second container 104. In addition, a part of the air flow blows out from the first air outlet 206 and flows above the cover plate 201, then flows downward along the front side of the first container 103, and finally flows back to the return air outlet 401 from the bottom of the second container 104. That is, when the air duct assembly is in the second state, the air flow blows towards the second ventilation opening 207 and the cover plate 201. Since the cold air slowly enters the first container 103 and directly blows into the second container 104, the first container 103 and the second container 104 can be quickly cooled and stored, and simultaneous air supply to the upper and lower layers can be achieved. In addition, less moisture is lost inside the first container 103, and more moisture is lost inside the second container 104, presenting a distribution pattern of high humidity in the upper layer and low humidity in the lower layer, realizing dry and wet separate storage.

[0073] Therefore, by using the air duct assembly to control the air flow direction, opening or closing the third air vent 208, the humidity and temperature inside the second container 104 can be adjusted, and the temperature inside the first container 103 can also be adjusted to meet the storage condition requirements of different types of food ingredients.

[0074] Referring to Figure 6 As shown, it can be understood 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, and the first air duct 601 and the second air duct 602 are independent of each other. The air supply damper 202 is a double damper, and the air supply damper 202 is used to open at least one of the first air duct 601 and the second air duct 602 to enable the above-mentioned air duct assembly to be in the first state or the second state. The air supply damper 202 is located between the freezer compartment 204 and the variable temperature compartment 102, and its function is to allow the freezer compartment 204 to supply cold air to the variable temperature compartment 102 through the freezing air duct 603 for temperature control.

[0075] Among them, referring to Figure 2 and Figure 6 As shown, the first container 103 is provided with a first ventilation opening 212. The first ventilation opening 212 communicates the inside and the outside of the first container 103, and can enable the cold air generated by the refrigeration system in the refrigerator to enter the inside of the first container 103 to achieve rapid cooling. The air outlet end of the first air duct 601 is provided with a first air vent 206, the first air vent 206 faces the upper part of the cover plate 201, the air outlet end of the second air duct 602 is provided with a second air vent 213 and a third air vent 208, the second air vent 213 faces the first ventilation opening 212, and the third air vent 208 faces the second ventilation opening 207.

[0076] When the air duct assembly is in the first state, the air supply damper 202 opens the first air duct 601, and the cold air conveyed by the freezing air duct 603 is conveyed to the upper part of the cover plate 201 through the first air vent 206. The cold air surrounds the first container 103 and the second container 104 and returns to the freezer compartment 204 through the air return opening 401. Since the cold air does not directly enter the first container 103 and the second container 104, it is not easy for the cold air to take away the internal moisture of the first container 103 and the second container 104, ensuring high humidity for the upper sliding tray and the lower drawer.

[0077] When the air duct assembly is in the second state, the air supply damper 202 opens the second air duct 602. The cold air conveyed by the freezing air duct 603 is conveyed to the inside of the first container 103 through the second air vent 213 and conveyed to the inside of the second container 104 through the third air vent 208. Since the cold air directly blows into the inside of the first container 103 and the second container 104, the first container 103 and the second container 104 can be rapidly cooled to meet the performance requirements such as storage temperature and freezing capacity.

[0078] It should be noted that in some other embodiments, when the air duct assembly is in the second state, the air supply damper 202 opens the second air duct 602 and can close the first air duct 601. At this time, the air flow can only flow into the interiors of the first container 103 and the second container 104 and does not flow to the upper part of the cover plate 201.

[0079] With the rise of fresh food e-commerce in recent years, people's demand for long-term storage of meat and fresh food ingredients has gradually shifted to short-term storage. In recent years, the wide-range variable temperature function has been favored by users because of its large storage space and flexible switching between refrigeration and freezing. Users can flexibly adjust the appropriate storage function according to actual storage needs. For example, when storing fruits and vegetables, the variable temperature drawer can be adjusted to the refrigeration gear (0°C to 5°C), and when storing meat, it can be adjusted to the soft freezing / freezing gear (below -1°C, such as -18°C, -24°C, -30°C, -40°C, -60°C).

[0080] Refer to Figure 7 As shown, it can be understood that when the user sets the variable temperature compartment 102 to the refrigeration gear, that is, when the temperature of the variable temperature compartment 102 is between 0°C and 5°C, the air supply damper 202 opens the first air duct 601 and closes the second air duct 602. The first air outlet 206 can supply air, while the second air outlet 213 and the third air outlet 208 cannot supply air. The cold air does not directly enter the first container 103 and the second container 104, avoiding taking away the moisture of the ingredients and realizing the high-humidity function of the whole space.

[0081] Refer to Figure 4 and Figure 7 As shown, it can be understood that the 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 then returns to the freezer 204 through the air return port 401. Thus, the temperature of the internal ingredients can be reduced through heat exchange on the outer wall, improving the low-temperature fresh-keeping environment.

[0082] Refer to Figure 8 As shown, it can be understood that when the user sets the variable temperature compartment 102 to the freezing gear, that is, when the temperature of the variable temperature compartment 102 is below -1°C, the air supply damper 202 opens the first air duct 601 and the second air duct 602. The first air outlet 206, the second air outlet 213 and the third air outlet 208 can all supply air. The cold air directly enters the first container 103 and the second container 104 and is also delivered to the upper part of the cover plate 201. Therefore, it can ensure the rapid cooling of the first container 103 and the second container 104, accelerate the cooling speed of the ingredients, help the temperature of the ingredients reach the set temperature, and improve the fresh-keeping effect. It can be understood that because the set temperature of the freezing gear is relatively low, if the cooling speed of the ingredients is very slow, it is possible that the temperature of the ingredients cannot reach the set temperature in a short time, ultimately resulting in a poor fresh-keeping effect.

[0083] It should be noted that in some other embodiments, when the variable temperature chamber 102 is set to the refrigeration mode, the air supply damper 202 opens the first air duct 601 and the second air duct 602, and the first air outlet 206, the second air outlet 213, and the third air outlet 208 can all supply air.

[0084] It can be understood that according to the above embodiments, other embodiments can be extended, that is, the variable temperature chamber 102 can operate in the first gear and the second gear, and the temperature of the variable temperature chamber 102 in the first gear is higher than the temperature of the variable temperature chamber 102 in the second gear. When the variable temperature chamber 102 is set to the first gear and the current temperature of the variable temperature chamber 102 is greater than the set temperature of the first gear, the air duct assembly is opened at this time to realize ventilation, and the air duct assembly is in the first state to realize high humidity in the whole space. When the variable temperature chamber 102 is set to the second gear and the current temperature of the variable temperature chamber 102 is greater than the set temperature of the second gear, the air duct assembly is opened at this time to realize ventilation, and the air duct assembly is in the second state, and the first container 103 realizes constant temperature and high humidity.

[0085] It should be noted that when the variable temperature chamber 102 is in the first gear or the second gear, that is, when the current temperature of the variable temperature 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.

[0086] In summary, the functions of the breathable micropores 301 are as follows: ① When switched to the refrigeration mode, part of the water vapor can escape to the outside of the cover plate 201 through the breathable micropores 301, preventing the berries from mildewing due to the excessive humidity in the first container 103 and meeting the humidity requirements of 85%-95% for fruit ingredients; ② When switched to the freezing mode, the cold air flowing through the upper part of the cover plate 201 penetrates into the first container 103 through the breathable micropores 301, which can improve the freezing and cooling speed; ③ When defrosting the freezer, it can prevent the hot air generated by the heating wire from directly entering the first container 103 and causing a large impact on the temperature of the ingredients, resulting in a large fluctuation in the temperature of the ingredients.

[0087] Refer to Figure 7 As shown, it can be understood that the first air duct 601 and the second air duct 602 are arranged 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 the cold air flows upward from the bottom of the second container 104 to the upper part of the first container 103 and the upper part of the second container 104, increasing the heat exchange area between the first air duct 601 and the second air duct 602 and the first container 103 and the second container 104, which is beneficial to improving the heat exchange efficiency.

[0088] It can be understood that in some other embodiments, the first air duct 601 and the second air duct 602 can also be arranged in the up-down direction.

[0089] Refer to Figure 7As shown, it can be understood that the first air duct 601 includes a first air outlet branch duct 701 and a second air outlet branch duct 702, and the first air outlet branch duct 701 and the second air outlet branch duct 702 are arranged in the left - right direction. Such an arrangement mainly has a guiding effect. Generally, the return air outlet 401 is on the left side in the figure. Since the first air duct 601 is on the right side in the figure, part of the air is guided to the right side to ensure that the temperature on the right side can be better reduced. If the first air outlet branch duct 701 and the second air outlet branch duct 702 are combined together, the temperature on the right side may be too high because most of the air directly flows back to the return air outlet 401 on the left side. That is to say, by dividing the first air duct 601 into the first air outlet branch duct 701 and the second air outlet branch duct 702 and arranging the first air outlet branch duct 701 and the second air outlet branch duct 702 in the left - right direction, the uniformity of temperature distribution can be improved.

[0090] Referring to Figure 9 As shown, it can be understood that in some embodiments, the main difference from the Figures 6 to 8 embodiment shown is that the second air duct 602 only has a third air outlet 208 facing the second ventilation opening 207 and does not have a second air outlet 213 facing the first ventilation opening 212.

[0091] When the air duct assembly is in the first state, the air supply air damper 202 opens the first air duct 601, and the cold air conveyed by the refrigeration air duct 603 is conveyed to the upper part of the cover plate 201 through the first air outlet 206. The cold air surrounds the first container 103 and the second container 104 and returns to the freezer 204 through the return air outlet 401. Since the cold air does not directly enter the first container 103 and the second container 104, it is not easy for the cold air to take away the moisture inside the first container 103 and the second container 104, ensuring high humidity for the upper sliding tray and the lower drawer.

[0092] When the air duct assembly is in the second state, the air supply air damper 202 opens the second air duct 602, and the cold air conveyed by the refrigeration air duct 603 is conveyed to the inside of the second container 104 through the third air outlet 208. Since the cold air directly blows into the inside of the second container 104, the second container 104 can be quickly cooled. At the same time, the cold air entering the inside of the second container 104 will also exchange heat with the bottom of the first container 103, accelerating the cooling rate of the first container 103 and meeting the performance requirements such as temperature storage and freezing capacity. And no cold air directly enters the inside of the first container 103, which is beneficial to maintaining the high - humidity state of the first container 103 and realizing the dry - wet separate storage of the first container 103 and the second container 104.

[0093] In addition, referring to Figure 9As shown, it can be understood that the first air duct 601 includes a first air outlet branch duct 701 and a second air outlet branch duct 702. The first air outlet branch duct 701 and the second air outlet branch duct 702 are arranged in the left-right direction, and the air outlet end of the second air outlet branch duct 702 is located above the air outlet end of the second air duct 602. Since the first air duct 601 and the second air duct 602 are arranged in the left-right direction, the second air duct 602 occupies a part of the space, affecting the cover plate 201 where the cold air covers a larger range, which is not conducive to the temperature uniformity. And Figure 9 In the embodiment shown, by setting the air outlet end of the second air outlet branch duct 702 above the air outlet end of the second air duct 602, the air outlet range is expanded, and the area covering the cover plate 201 is larger, thereby improving the temperature uniformity.

[0094] It should be noted that Figure 9 In the embodiment shown, the air outlet of the second air duct 602 does not blow towards the cover plate 201. In some other embodiments, the air outlet of the second air duct 602 can also blow towards the cover plate 201, that is, after the cold air enters the second air duct 602, a part of the air flow will blow towards the cover plate 201.

[0095] Referring to Figures 10 to 13 As shown, it can be understood that in some embodiments, the air duct assembly includes an air duct cover 203. A single air supply damper 202 is provided at the bottom of the air duct cover 203. The air supply damper 202 connects the freezer 204 and the variable temperature chamber 102, and its function is to allow the freezer 204 to supply cold air to the variable temperature chamber 102 for temperature control. A duct foam 205 is provided inside the variable temperature air duct cover 203, and a channel for guiding the air flow direction is formed in the duct foam 205. The channel includes a single air supply duct 1001. The air supply duct 1001 has a first air outlet 206 and a third air outlet 208. The first air outlet 206 faces the cover plate 201, and the third air outlet 208 faces the second ventilation opening 207. The air duct assembly is provided with an air control device for opening or closing the third air outlet 208, which can adjust the humidity and temperature inside the second container 104 to meet the storage condition requirements of different types of food ingredients.

[0096] When the air duct assembly is in the first state, the air supply damper 202 opens the air supply duct 1001, and the air control device shields the third air outlet 208. The cold air conveyed by the freezing air duct 603 is conveyed to the upper part of the cover plate 201 through the first air outlet 206. The cold air surrounds the first container 103 and the second container 104 and returns to the freezer 204 through the air return opening 401. Since 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 internal moisture of the first container 103 and the second container 104, ensuring high humidity for the upper sliding tray and the lower drawer.

[0097] When the air duct assembly is in the second state, the air supply damper 202 opens the air supply duct 1001, the air control device opens the third air outlet 208, and the cold air conveyed by the refrigeration duct 603 is conveyed to the upper part of the cover plate 201 through the first air outlet 206 and then conveyed to the inside of the second container 104 through the third air outlet 208. Since the cold air is directly blown into the inside of the second container 104, the first container 103 and the second container 104 can be quickly cooled, realizing dry-wet separation storage and meeting the performance requirements such as temperature storage and refrigeration capacity.

[0098] When the user sets the variable temperature chamber 102 to the refrigeration gear, if the air duct assembly is in the first state, the full-space high-humidity function can be realized. If the air duct assembly is in the second state, dry-wet separation storage can be realized and the cooling rate can be accelerated.

[0099] When the user sets the variable temperature chamber 102 to the freezing gear, and the air duct assembly is in the second state, it can be quickly cooled to the set temperature, meeting the performance requirements such as temperature storage and refrigeration capacity.

[0100] Refer to Figures 11 to 13 As shown, it can be understood that the air control device includes a wind deflector 1101 and a driving member 1301. The driving member 1301 drives the wind deflector 1101 to move to open or close the third air outlet 208. The driving member 1301 can be a motor. A gear 1201 is provided at the output end of the motor, and a rack portion 1202 meshing with the gear 1201 is provided on the wind deflector 1101. The motor drives the gear 1201 to rotate, thereby driving the rack portion 1202 to move, and further driving the wind deflector 1101 to move.

[0101] Refer to Figure 13 As shown, it can be understood that the air duct cover 203 is provided with a sliding groove 1302, and the wind deflector 1101 is installed in the sliding groove 1302 to slide in the up-down direction along the sliding groove 1302, making the movement direction of the wind deflector 1101 more accurate and the movement process smoother.

[0102] Refer to Figure 13 As shown, it can be understood that the wind deflector 1101 is provided with grid holes 1303. When the positions of the grid holes 1303 correspond to those of the third air outlet 208, the third air outlet 208 is opened, so that the cold air can enter the inside of the second container 104 through the second ventilation opening 207. When the positions of the grid holes 1303 are completely misaligned with those of the third air outlet 208, the third air outlet 208 is shielded by the wind deflector 1101, and the cold air does not directly enter the second container 104.

[0103] It should be noted that in some other embodiments, the third air outlet 208 can also be closed by shielding the third air outlet 208 with the wind deflector 1101, and the third air outlet 208 can be opened by the wind deflector 1101 leaving the third air outlet 208.

[0104] It can be understood that in some other embodiments, the driving member 1301 can also drive the wind deflector 1101 to move by means of a transmission mechanism such as a pulley mechanism or a belt drive mechanism. Additionally, in some other embodiments, the driving member 1301 can also be configured to rotate the wind deflector 1101 to open or close the third air outlet 208.

[0105] Referring to Figure 2 and Figure 14 As shown, it can be understood that the front part of the first container 103 is provided with a front plate 209 and a bent plate 210. The bent plate 210 is bent downward from the upper end of the front plate 209. There is a humidity adjustment space 211 between the front plate 209 and the bent plate 210. The lower part of the humidity adjustment space 211 is open, so as to communicate with the second opening 106. The front plate 209 is used to isolate the internal space of the first container 103 and the humidity adjustment space 211.

[0106] Referring to Figure 2 and Figure 14 As shown, it can be understood that a humidification component 108 is installed at the front part of the first container 103. Both sides of the humidification component 108 are provided with mist outlets. One side mist outlet of the humidification component 108 humidifies the internal space of the first container 103, and the other side mist outlet humidifies the second opening 106.

[0107] Referring to Figure 14 and Figure 15 As shown, it can be understood that the humidification component 108 includes a liquid storage box 1401, a moisture-permeable membrane, a fixed cover 1503, and an adjustment component. The liquid storage box 1401 is arranged in the first container 103. Water-permeable holes are respectively provided on both sides of the liquid storage box 1401 to communicate with the first container 103 and the second container 104 respectively. And each side of the water-permeable holes is covered with a moisture-permeable membrane. The moisture-permeable membrane allows mist to pass through while blocking liquid from overflowing. That is, the function of the moisture-permeable membrane: transport the liquid water in the liquid storage box 1401 to the surface of the moisture-permeable membrane to enrich it into water molecules, forming a water-wetting membrane. The fixed cover 1503 is located outside the moisture-permeable membrane and fixes the moisture-permeable membrane to the liquid storage box 1401. A seal is arranged between the fixed cover 1503 and the moisture-permeable membrane to prevent liquid leakage. The fixed cover 1503 is provided with a through hole 1505. The adjustment component includes two baffle plates 1402. Each baffle plate 1402 corresponds to one side of the fixed cover 1503 and is used to open or close the through hole 1505 of one fixed cover 1503. When the baffle plate 1402 opens the through hole 1505 of the fixed cover 1503, the mist on the corresponding side can come out. When the baffle plate 1402 closes the through hole 1505 of the fixed cover 1503, the mist on the corresponding side is sealed.

[0108] Specifically, an installation groove 1403 is provided in the internal space of the first container 103. The liquid storage box 1401 is placed in the installation groove 1403. The front plate 209 is provided with a moisture-permeable window, which communicates the humidity adjustment space 211 and the liquid storage box 1401. A part of the mist passes through the moisture-permeable window from the water-permeable holes on the front side of the liquid storage box 1401 and enters the humidity adjustment space 211, and then enters the second container 104 for humidification through the second open port 106 downward. A part of the mist directly enters the internal space of the first container 103 for humidification from the water-permeable holes on the rear side of the liquid storage box 1401.

[0109] The cover plate 201 is arranged at the first open port 105 of the first container 103 to make the first container 103 form a relatively sealed space. The first container 103 is located at the second open port 106 of the second container 104 to make the second container 104 form a relatively sealed space. Although the water loss of the first container 103 and the second container 104 is reduced, after working for a period of time, the humidity drops and may not meet the humidity requirements. Or items with higher required humidity are placed in the first container 103 and the second container 104, and the original space humidity cannot be increased. In the embodiment of the present invention, by adding the humidification component 108, water vapor or mist is input into the first container 103 and the second container 104 as needed to achieve the effect of actively increasing humidity.

[0110] It should be noted that in some other embodiments, a humidification port can also be provided only on one side of the humidification component 108, and the mist is respectively transported to the first container 103 and the second container 104 through two different channels. In some other embodiments, the humidification component 108 can also be arranged in the second container 104 or on the drawer board 107. Figure 14 The advantages of the shown embodiment are that the humidification component 108 can be easily assembled, accurately transport the mist to the first container 103 and the second container 104, and in addition, it is also convenient to adjust the humidification component 108.

[0111] Generally speaking, the working process of the humidification component 108 includes an atomization process and a steam transportation process. The atomization process is to convert liquid water into water vapor to achieve the purpose of humidification. In this process, electrical energy is converted into mechanical energy, and high-frequency oscillation is generated through the atomization sheet to break the liquid water droplets into tiny water droplets, thereby forming water vapor. The steam transportation process is to transport the generated steam to the space that needs to be humidified to achieve the humidification effect. In this process, the water vapor can be transported to the area that needs to be humidified through pipelines or fans, and at the same time, the humidification process can be intelligently controlled through a humidity sensor and a control circuit to achieve a better humidification effect.

[0112] As is well known, in addition to temperature, humidity is also one of the important factors affecting the storage of fruits and vegetables. Maintaining a high-humidity environment helps to extend the fresh-keeping period of fruits and vegetables, and drawer humidification is a good way to maintain high humidity for a long time. However, for the variable-temperature compartment 102, when the variable-temperature compartment 102 is switched to the second gear, that is, the temperature of the variable-temperature compartment 102 is below -1°C, the liquid in the humidifying component 108 will freeze. When switching from the freezing gear to the refrigerating gear, the humidifying component 108 fails due to freezing, resulting in a poor fresh-keeping effect for fruits and vegetables.

[0113] Referring to Figure 14 and Figure 15 As shown, it can be understood that the refrigerator according to the embodiment of the present invention includes a heater 1405 for heating the liquid storage box 1401. When switching from the freezing gear to the refrigerating gear, the heater 1405 is started to quickly melt the ice in the liquid storage box 1401, which can avoid the failure problem.

[0114] Referring to Figure 14 As shown, it can be understood that the adjusting component includes a connecting piece 1404 and a lever 109. The connecting piece 1404 has two retaining pieces 1402, so that the two retaining pieces 1402 move synchronously. The connecting piece 1404 is located below the liquid storage box 1401. In order to facilitate the connecting piece 1404 to drive the two retaining pieces 1402 to move, a cushion block can be provided in the installation groove 1403, and the liquid storage box 1401 is placed on the cushion block, so that there is a gap between the bottom wall of the lever 109 and the bottom wall of the liquid storage box 1401, and the connecting piece 1404 can move in this gap. The lever 109 is used to move the retaining piece 1402 horizontally. The lever 109 can be connected to the retaining piece 1402 or the connecting piece 1404. The lever 109 can be manually toggled, or a motor can be provided to drive the lever 109 to move. The lever 109 can be fixedly connected to the retaining piece 1402, or can be hinged, or the lever 109 abuts against the retaining piece 1402, and the lever 109 is hinged to the front plate 209, and the lever principle is used to push the retaining piece 1402 to move, which is more labor-saving.

[0115] It should be noted that in some other embodiments, the connecting piece 1404 can also be located above the liquid storage box 1401.

[0116] Referring to Figure 15As shown, it can be understood that by adding a heater 1405 at the bottom of the humidifying component 108, the heat generated by the heater 1405 is used to quickly melt the ice in the liquid storage box 1401, avoiding the failure of the humidifying component 108. Specifically, an installation cavity and an installation cover 1501 are provided at the bottom of the liquid storage box 1401. The heater 1405 is installed in the installation cavity, and the installation cover 1501 closes the installation cavity. By arranging the heater 1405 in the installation cavity of the liquid storage box 1401, the heater 1405 is closer to the liquid, thus increasing the rate of rapid ice melting. Also, since the connecting piece 1404 is located below the liquid storage box 1401, arranging the heater 1405 in the installation cavity of the liquid storage box 1401 can also prevent the connecting piece 1404 from blocking heat transfer.

[0117] It should be noted that in some other embodiments, the heater 1405 can also be arranged in the installation groove 1403 and can be located on the side of the liquid storage box 1401.

[0118] Refer to Figure 15 As shown, it can be understood that an electrode seat 1502 is provided on the outer side of the liquid storage box 1401. The heater 1405 is connected to a wiring board 1504. The wiring board 1504 is located at one end of the heater 1405. The wiring board 1504 is connected to a pair of metal electrodes. The installation cover 1501 is provided with electrode holes 1507. The positions of the electrode holes 1507 correspond to the metal electrodes. The metal electrodes pass through the electrode holes 1507 of the installation cover 1501 and contact the electrodes of the electrode seat 1502 to be energized.

[0119] It can be understood that when the first container 103 is configured as an upper sliding tray and needs to be taken out of the box body 101, the problem of power supply for the heater 1405 needs to be solved.

[0120] Refer to Figure 14 As shown, it can be understood that the refrigerator includes a wireless charging component. The wireless charging component includes a wireless transmitting module 1406 and a wireless receiving module 1407. The second container 104 is provided with a drawer board 107. The wireless transmitting module 1406 is arranged on the drawer board 107. The wireless receiving module 1407 and the heater 1405 are arranged in the first container 103. The wireless receiving module 1407 and the heater 1405 are electrically connected. For example, the wireless receiving module 1407 is energized through a connecting wire to the electrode seat 1502.

[0121] The implementation methods of wireless charging are as follows:

[0122] Electromagnetic induction charging: Through the principle of electromagnetic induction, the current is converted into a magnetic field, and then the magnetic field is converted into current at the receiving end to achieve wireless charging.

[0123] Magnetic field resonance charging: Through the resonance principle, magnetic fields with the same frequency are formed at the transmitting end and the receiving end, thus achieving wireless charging.

[0124] Electric field induction charging: Through the principle of electric field induction, electrical energy is converted into an electric field, and then the electric field is converted into electrical energy at the receiving end to achieve wireless charging.

[0125] Electromagnetic wave charging: Wireless charging is achieved by transmitting energy through electromagnetic waves.

[0126] In some embodiments, the temperature control program of heater 1405 is as follows:

[0127] When it is detected that the set temperature of the variable temperature chamber 102 is greater than 0°C and the current temperature is less than 0°C, it is determined that the variable temperature chamber 102 is switched from the freezing gear to the refrigeration gear, and the heater 1405 is turned on for 20 minutes to 1 hour;

[0128] When the set temperature of the variable temperature chamber 102 is monitored to be 0°C to -7°C and the current temperature is greater than 0°C, in order to prevent the water in the water box from freezing too quickly and forming ice that breaks the liquid storage box 1401, the heater 1405 is turned on at half power for 30 minutes to 1 hour;

[0129] When it is monitored that the set temperature of the variable temperature chamber 102 is below -7°C and the current temperature is greater than 0°C, in order to prevent the water in the water box from freezing too quickly and forming ice that breaks the liquid storage box 1401, the heater 1405 is turned on at full power for 30 minutes to 1 hour.

[0130] It should be noted that the specific parameters of time, power and temperature in the above examples can be adjusted according to actual conditions.

[0131] It can be understood that the baffle 1402 is provided with a humidification hole 1506, and the humidification hole 1506 is used to communicate with the through hole 1505. The lever 109 drives the baffle 1402 to move. When the humidification hole 1506 coincides with the through hole 1505, the through hole 1505 of the fixed cover 1503 is opened so that the mist on the corresponding side can come out. When the humidification hole 1506 and the through hole 1505 are completely staggered, the through hole 1505 of the fixed cover 1503 is closed so that the mist on the corresponding side is blocked.

[0132] Reference Figure 16 As shown, the lever 109 can be moved to the first position. When the lever 109 is in the first position, the humidification hole 1506 of the baffle 1402 on the front side partially overlaps with the corresponding through hole 1505 to achieve communication, thereby transporting the mist to the front side of the liquid storage box 1401, entering the humidity adjustment space 211, and finally entering the second container 104 to increase the humidity.

[0133] Reference Figure 17As shown, when the lever 109 is in the first position, the humidifying holes 1506 of the baffle 1402 at the rear side are completely staggered from the corresponding through holes 1505, thereby closing the corresponding through holes 1505, and thus no mist flows out from the rear side of the liquid storage box 1401, and the humidity of the first container 103 is not actively increased. That is to say, when it is necessary to increase the humidity of the second container 104 while not increasing the humidity of the first container 103, the lever 109 can be moved to the first position.

[0134] Refer to Figure 18 As shown, the lever 109 can be moved to the second position. When the lever 109 is in the second position, the humidifying holes 1506 of the baffle 1402 at the front side partially overlap with the corresponding through holes 1505 to achieve communication, so as to convey the mist to the front side of the liquid storage box 1401, enter the humidity adjustment space 211, and finally enter the second container 104 to increase the humidity.

[0135] Refer to Figure 19 As shown, when the lever 109 is in the second position, the humidifying holes 1506 of the baffle 1402 at the rear side partially overlap with the corresponding through holes 1505 to achieve communication, so as to convey the mist to the rear side of the liquid storage box 1401 and enter the first container 103 to increase the humidity. That is to say, when it is necessary to increase the humidity of both the first container 103 and the second container 104, the lever 109 can be moved to the second position.

[0136] Refer to Figure 20 As shown, the lever 109 can be moved to the third position. When the lever 109 is in the third position, the humidifying holes 1506 of the baffle 1402 at the front side are completely staggered from the corresponding through holes 1505, thereby closing the corresponding through holes 1505, and thus no mist flows out from the front side of the liquid storage box 1401, and the humidity of the second container 104 is not actively increased.

[0137] Refer to Figure 21 As shown, it can be understood that when the lever 109 is in the third position, the humidifying holes 1506 of the baffle 1402 at the rear side partially overlap with the corresponding through holes 1505 to achieve communication, so as to convey the mist to the rear side of the liquid storage box 1401 and enter the first container 103 to increase the humidity. That is to say, when it is necessary to increase the humidity of the first container 103 while not increasing the humidity of the second container 104, the lever 109 can be moved to the third position.

[0138] Therefore, the humidifying assembly 108 of this embodiment can simultaneously adjust the humidifying states in two directions through the lever 109, and can also make the humidifying states in the two directions the same or different. In other words, it can humidify one side while not humidifying the other side, or humidify both sides simultaneously.

[0139] It can be understood that, in order to achieve the above functions, the humidifying holes 1506 of the baffles 1402 on the front and rear sides can be offset, while the through holes 1505 on the front and rear sides are arranged in a corresponding manner. Thus, when the humidifying holes 1506 and the through holes 1505 on one side coincide, the humidifying holes 1506 and the through holes 1505 on the other side are offset, and partial coincidence of the humidifying holes 1506 and the through holes 1505 on the front and rear sides can also be achieved. It is also possible to make the humidifying holes 1506 of the baffles 1402 on the front and rear sides correspond, while the through holes 1505 on the front and rear sides are arranged in an offset manner.

[0140] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
