Description

Technical Field

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

[0002] As we all know, in addition to temperature, humidity is also one of the important factors that affect the storage of fruits and vegetables. Maintaining a high humidity environment helps extend the shelf life of fruits and vegetables. If the drawer is left open, it is conducive to rapid cooling, but the cold wind takes away the moisture released by the fruits and vegetables in the drawer, resulting in low humidity. If the drawer is set to a closed state, although the drawer can maintain a high humidity state, the external cold air cannot enter the drawer to exchange heat due to the closed drawer, resulting in a very slow cooling speed of the ingredients, which cannot be quickly reduced to the set temperature, and cannot meet the storage conditions of the humidity required by different types of ingredients, affecting the preservation effect. Summary of the invention

[0053] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as a limitation to the present invention.

[0054] In the description of the present invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the 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 cannot be understood as a limitation to the present invention.

[0055] In the description of the present invention, the meaning of several is one or more, the meaning of multiple is two or more, greater than, less than, exceeding, etc. are understood as not including the present number, and above, below, within, etc. are understood as including the present number. If the first and second are described only for the purpose of distinguishing technical features, they cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence relationship of the indicated technical features.

[0056] In the description of the present invention, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense. 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.

[0057] Refer to Figure 1As shown in the figure, the refrigerator according to the embodiment of the present invention includes a box body 101, and a variable temperature compartment 102 is provided inside the box body 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.

[0058] Referring to Figure 1 As shown in the figure, 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 is completely lapped on the upper part of the lower drawer, a relatively sealed space is formed in the lower drawer. The gap range between the second container 104 and the first container 103 is 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 out or pushing in action of the second container 104. And when cold air is introduced into the second container 104, it can make the air flow entering the second container 104 flow out and maintain a certain pressure.

[0059] 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.

[0060] Referring to Figure 1 and Figure 2 As shown in the figure, 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 compartment 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 compartment 102 and using the front end of the second container 104 to close the lower half of the entrance of the variable temperature compartment 102, the drawer board 107 of the second container 104 closes the entire entrance of the variable temperature compartment 102, which can reduce the gap between the first container 103 and the second container 104, improve the sealing performance, and reduce cold air leakage.

[0061] Referring to Figure 2As shown, it can be understood that the refrigerator further includes a cover plate 201 disposed at the first opening 105 so that the first container 103 forms a relatively enclosed 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 facilitates the sliding of the first container 103 to smoothly perform the operation of pulling out or pushing in the first container 103. Refer to Figure 3 As shown, the cover plate 201 is provided with a plurality of breathable micropores 301 configured to allow air circulation inside and outside the first container 103.

[0062] 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 ranges from 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 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%.

[0063] Refer to Figure 3 As shown, it can be understood that in some embodiments, the aperture diameter of the breathable micropores 301 is D, and the size range of D is from 3.7 mm to 3.9 mm. When D is less than 3.7 mm, it is difficult to achieve air circulation inside and outside the first container 103. When D is greater than 3.9 mm, it is difficult to maintain a high humidity state inside the first container 103.

[0064] 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.

[0065] 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.

[0066] Refer to Figure 3 As shown, it can be understood that in some embodiments, two adjacent rows of breathable micropores 301 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.

[0067] Referring to Figure 2 As 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.

[0068] 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 adjusted correspondingly.

[0069] Referring 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 inside the duct foam 205. By controlling the airflow direction, the air duct assembly has different working states, and then the refrigerator enters different working modes.

[0070] Referring 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 bypasses 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 air-permeable 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 air-permeable 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 air-permeable micropores 301, which can prevent the berry fruits 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 enclosed space, and the first container 103 and the second container 104 cooperate to form a relatively enclosed 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.

[0071] 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 is achieved. In addition, less moisture is lost inside the first container 103, and more moisture is lost inside the second container 104, showing a distribution pattern of high humidity in the upper layer and low humidity in the lower layer, realizing dry-wet separate storage.

[0072] Therefore, by using the air duct assembly to control the air flow direction, opening or closing the third air outlet 208, the humidity and temperature in the second container 104 can be adjusted, and the temperature in the first container 103 can also be adjusted to meet the storage condition requirements of different types of food ingredients.

[0073] 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. The first air duct 601 and the second air duct 602 are independent of each other. The air supply air damper 202 is a double air damper, and the air supply air 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 air 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 deliver cold air to the variable temperature compartment 102 through the freezing air duct 603 for temperature control.

[0074] 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 outlet 206, the first air outlet 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 outlet 213 and a third air outlet 208, the second air outlet 213 faces the first ventilation opening 212, and the third air outlet 208 faces the second ventilation opening 207.

[0075] 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 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 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 moisture inside the first container 103 and the second container 104, ensuring high humidity for the upper sliding tray and the lower drawer.

[0076] 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 freezing air duct 603 is conveyed to the inside of the first container 103 through the second air outlet 213 and 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 first container 103 and the second container 104, the first container 103 and the second container 104 can be quickly cooled to meet the performance requirements such as storage temperature and freezing capacity.

[0077] 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 interior of the first container 103 and the second container 104, and does not flow to the upper part of the cover plate 201.

[0078] With the rise of fresh food e-commerce in recent years, people's demand for meat and fresh food ingredients has gradually shifted from long-term storage to short-term storage. In recent years, the wide temperature change 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).

[0079] Refer to Figure 7 As shown, it can be understood that when the user sets the variable temperature chamber 102 to the refrigeration gear, that is, when the temperature of the variable temperature chamber 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.

[0080] 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 the heat exchange on the outer wall, improving the low-temperature preservation environment.

[0081] Refer to Figure 8 As shown, it can be understood that when the user sets the variable temperature chamber 102 to the freezing gear, that is, when the temperature of the variable temperature chamber 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 drop to the set temperature, and improve the preservation 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 drop to the set temperature in a short time, ultimately resulting in a poor preservation effect.

[0082] 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.

[0083] 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 achieve ventilation, and the air duct assembly is in the first state to achieve high humidity in the entire 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 achieve ventilation, and the air duct assembly is in the second state, and the first container 103 realizes constant temperature and high humidity.

[0084] 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 berries from mildewing due to 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 an impact on the temperature of the ingredients, resulting in a large fluctuation in the temperature of the ingredients.

[0085] 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. 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 is increased, which is beneficial to improving the heat exchange efficiency.

[0086] 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.

[0087] 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 inlet 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 lowered. 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 inlet 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 the temperature distribution can be improved.

[0088] 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.

[0089] 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 outlet 206. The cold air surrounds the first container 103 and the second container 104 and returns to the freezing chamber 204 through the return air inlet 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.

[0090] When the air duct assembly is in the second state, the air supply damper 202 opens the second air duct 602, and the cold air conveyed by the freezing 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, meeting 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.

[0091] 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 can cover 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 of the cover plate 201 covered is larger, thereby improving the temperature uniformity.

[0092] 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.

[0093] 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. Its function is to allow the freezer 204 to supply cold air to the variable - temperature chamber 102 for temperature control. Inside the variable - temperature air duct cover 203, there is an air duct foam 205. A channel for guiding the air flow direction is formed in the air duct foam 205. The channel includes an air supply air duct 1001. The air supply air 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. The air - control device is used to open or close the third air outlet 208, and can adjust the humidity and temperature inside the second container 104 to meet the storage condition requirements of different types of food ingredients.

[0094] When the air duct assembly is in the first state, the air supply damper 202 opens the air supply air 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 return air 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.

[0095] 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 down, realizing dry-wet separate storage and meeting the performance requirements such as temperature storage and refrigeration capacity.

[0096] 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 separate storage can be realized, and the cooling rate can be accelerated.

[0097] When the user sets the variable temperature chamber 102 to the freezing gear, when the air duct assembly is in the second state, it can be quickly cooled down to the set temperature, meeting the performance requirements such as temperature storage and refrigeration capacity.

[0098] Refer to Figures 11 to 13 As shown, it can be understood that the air control device includes a wind baffle 1101 and a driving member 1301. The driving member 1301 drives the wind baffle 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. The wind baffle 1101 is provided with a rack portion 1202 meshing with the gear 1201. The motor drives the gear 1201 to rotate, thereby driving the rack portion 1202 to move, and further driving the wind baffle 1101 to move.

[0099] 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 baffle 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 baffle 1101 more accurate and the movement process smoother.

[0100] Refer to Figure 13 As shown, it can be understood that the wind baffle 1101 is provided with grid holes 1303. When the positions of the grid holes 1303 correspond to 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 the third air outlet 208, the third air outlet 208 is shielded by the wind baffle 1101, and the cold air does not directly enter the second container 104.

[0101] 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 baffle 1101, and the third air outlet 208 can be opened by the wind baffle 1101 leaving the third air outlet 208.

[0102] It can be understood that in some other embodiments, the driving member 1301 can also drive the windshield 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 windshield 1101 to open or close the third air vent 208.

[0103] Referring to Figure 2 and Figure 14 as shown, it can be understood that a front plate 209 and a bending plate 210 are provided at the front part of the first container 103. The bending 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 bending 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.

[0104] Referring to Figure 2 and Figure 14 as shown, it can be understood that a humidifying component 108 is installed at the front part of the first container 103. Mist outlets are provided on both sides of the humidifying component 108. One mist outlet on one side of the humidifying component 108 humidifies the internal space of the first container 103, and the other mist outlet on the other side humidifies the second opening 106.

[0105] Referring to Figure 14 and Figure 15 as shown, it can be understood that the humidifying component 108 includes a liquid storage box 1401, a moisture-permeable membrane 1502, a fixing cover 1503 and an adjusting component. The liquid storage box 1401 is provided in the first container 103. Water permeable holes 1501 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 the water permeable holes 1501 on each side are covered with a moisture-permeable membrane 1502. The moisture-permeable membrane 1502 allows mist to pass through while blocking the overflow of liquid. That is, the function of the moisture-permeable membrane 1502 is to transport the liquid water in the liquid storage box 1401 to the surface of the moisture-permeable membrane 1502 to enrich it into water molecules, forming a water-wetting film. The fixing cover 1503 is located outside the moisture-permeable membrane 1502 and fixes the moisture-permeable membrane 1502 to the liquid storage box 1401. A sealing member 1504 is provided between the fixing cover 1503 and the moisture-permeable membrane 1502, which can prevent liquid leakage. The fixing cover 1503 is provided with through holes 1505. The adjusting component includes two baffle plates 1402. Each baffle plate 1402 corresponds to one side of the fixing cover 1503 and is used to open or close the through hole 1505 of one fixing cover 1503. When the baffle plate 1402 opens the through hole 1505 of the fixing cover 1503, the mist on the corresponding side can come out. When the baffle plate 1402 closes the through hole 1505 of the fixing cover 1503, the mist on the corresponding side is sealed.

[0106] 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, and the moisture-permeable window communicates with 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 1501 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 through the water-permeable holes 1501 on the rear side of the liquid storage box 1401.

[0107] The cover plate 201 is arranged at the first open port 105 of the first container 103 so that the first container 103 forms a relatively airtight space. The first container 103 is located at the second open port 106 of the second container 104 so that the second container 104 forms a relatively airtight 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 requirement. 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, achieving the effect of actively increasing humidity.

[0108] 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 arranged on the drawer plate 107. Figure 14 The advantages of the shown embodiment are that the humidification component 108 can be conveniently assembled and accurately transport the mist to the first container 103 and the second container 104. In addition, it is also convenient to adjust the humidification component 108.

[0109] 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. 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.

[0110] Refer to Figure 14As shown, it can be understood that the adjustment component includes a connecting member 1404 and a lever 109. The connecting member 1404 has two baffles 1402, so that the two baffles 1402 move synchronously. The connecting member 1404 is located below the liquid storage box 1401. In order to facilitate the connecting member 1404 to drive the two baffles 1402 to move, a pad can be set in the mounting groove 1403, and the liquid storage box 1401 is placed on the pad, so that there is a gap between the bottom wall of the liquid storage box 1401 and the bottom wall of the liquid storage box 1401, and the connecting member 1404 can move in the gap. The lever 109 is used to move the baffle 1402 in translation. The lever 109 can be connected to the baffle 1402 or the connecting member 1404. The lever 109 can be manually moved, or a motor can be set to drive the lever 109 to move. The lever 109 can be fixedly connected to the baffle 1402, or can be hinged, or the lever 109 can be in contact with the baffle 1402, and the lever 109 is hinged to the front plate 209, and the baffle 1402 is pushed to move using the lever principle, which is more labor-saving.

[0111] It should be noted that in some other embodiments, the connecting member 1404 may also be located above the liquid storage box 1401 .

[0112] 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.

[0113] Reference Figure 16 As shown, it can be understood that 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 located 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.

[0114] Reference Figure 17 As shown, it can be understood that when the lever 109 is located at the first position, the humidification hole 1506 of the baffle 1402 located at the rear side is completely staggered with the corresponding through hole 1505, thereby closing the corresponding through hole 1505, and then 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. In other words, when the humidity of the second container 104 needs to be increased and the humidity of the first container 103 does not need to be increased, the lever 109 can be moved to the first position.

[0115] ReferenceFigure 18 As shown, it can be understood that the lever 109 can be moved to the second position. When the lever 109 is in the second position, the humidification hole 1506 of the baffle 1402 located 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.

[0116] Reference Figure 19 As shown, it can be understood that when the lever 109 is located at the second position, the humidification hole 1506 of the baffle 1402 located at the rear side partially overlaps with the corresponding through hole 1505, thereby achieving communication, thereby transporting the mist to the rear side of the liquid storage box 1401 and entering the first container 103 to increase the humidity. In other words, when it is necessary to increase the humidity of the first container 103 and the second container 104, the lever 109 can be moved to the second position.

[0117] Reference Figure 20 As shown, it can be understood that the lever 109 can be moved to the third position. When the lever 109 is in the third position, the humidification hole 1506 of the baffle 1402 located on the front side is completely offset from the corresponding through hole 1505, thereby closing the corresponding through hole 1505, and 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.

[0118] Reference Figure 21 As shown, it can be understood that when the lever 109 is located at the third position, the humidification hole 1506 of the baffle 1402 located at the rear side partially overlaps with the corresponding through hole 1505, and communication is achieved, so that the mist is transported to the rear side of the liquid storage box 1401 and enters the first container 103 to increase the humidity. In other words, when the humidity of the first container 103 needs to be increased and the humidity of the second container 104 does not need to be increased, the lever 109 can be moved to the third position.

[0119] Therefore, the humidification component 108 of this embodiment can adjust the humidification state in two directions at the same time through the lever 109, and can also make the humidification state in the two directions the same or different. In other words, one side can be humidified and the other side not humidified, or both sides can be humidified at the same time.

[0120] 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 it is also possible to achieve partial coincidence of the humidifying holes 1506 and the through holes 1505 on the front and rear sides at the same time. It is also possible to make the humidifying holes 1506 of the baffles 1402 on the front and rear sides correspond to each other, while the through holes 1505 on the front and rear sides are arranged in an offset manner.

[0121] The embodiments of the present invention have been described in detail above with reference to 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.
