DETAILED DESCRIPTION

[0030] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0031] As described in the background technology, the actual air supply volume at each position inside the refrigeration room in the prior art has a large deviation from the theoretical design air supply volume, which affects the temperature uniformity inside the refrigeration room. The inventors have found that the reason for this problem is that the box body itself has thermal expansion and contraction during the foaming process, and the accuracy of the size of the refrigeration room is often difficult to guarantee. In particular, when the refrigerator is filled with insulation materials such as polyurethane with a high thermal expansion coefficient, the size of the inner liner of the refrigeration room will change greatly after the insulation material is foamed and cooled. Under different refrigeration environments, the deformation of the inner liner is different, which leads to a deviation between the actual production size of the ventilation gap between the inner liner and the shelf installed inside it and the theoretical design size, which in turn leads to a large deviation between the actual air supply volume in the refrigeration room and the theoretical design air supply volume, thereby affecting the temperature uniformity inside the refrigeration room.

[0032] Based on the above reasons, the present application provides a refrigerator. By adding an air volume adjustment mechanism between the shelves and the inner tank, the refrigerator at the production site or the user's home can adjust the ventilation area of ​​the ventilation gap between the shelves and the inner tank according to the design requirements, thereby ensuring the uniformity of the air supply volume at various positions in the refrigeration room, thereby improving the temperature uniformity in the refrigeration room.

[0033] refer to Figure 1The refrigerator 10 of this embodiment includes a box body 11 and a door body 12. The box body 11 is provided with a refrigeration compartment 1111. The door body 12 is connected to the box body 11, and the door body 12 can open or close the refrigeration compartment 1111 by, for example, rotating relative to the box body 11.

[0034] See also Figure 1 , Figure 3 and Figure 4 The box body 11 includes an inner liner 111, an outer shell 112 and a first heat-insulating layer 113. The inner liner 111 is used to form a refrigeration chamber 1111. The refrigeration chamber 1111 is used to store food and other items. The refrigeration chamber 1111 may be provided with a take-out port 1112, through which a user may put items into or take out items from the refrigeration chamber 1111. The outer shell 112 may be connected to the outside of the inner liner 111 to form the appearance of the refrigerator 10. The first heat-insulating layer 113 may be filled between the inner liner 111 and the outer shell 112 to block heat transfer between the refrigeration chamber 1111 and the external space of the box body 11. Optionally, the first heat-insulating layer 113 is made of various heat-insulating materials including but not limited to polyurethane or heat-insulating cotton.

[0035] The number of refrigeration chambers 1111 is not limited to one, and may be, for example, multiple. When there are multiple refrigeration chambers 1111, there are multiple inner tanks 111, and each inner tank 111 is arranged corresponding to each refrigeration chamber 1111. Specifically, the multiple refrigeration chambers 1111 may include a refrigeration chamber and a freezer chamber. The internal temperature of the refrigeration chamber is maintained, for example, between 0°C and 5°C, and items are stored in a refrigerated mode. The internal temperature of the freezer chamber is maintained, for example, between -30°C and 0°C, and items are stored in a frozen mode. In addition, the multiple refrigeration chambers 1111 may also include other chambers, for example, a vacuum chamber, a temperature-changing chamber, etc., which will not be repeated in this embodiment.

[0036] The refrigerator and the freezer can be arranged along the width direction of the refrigerator 10, or along the height direction of the refrigerator 10, or can be arranged in other ways, which are not limited here. When the refrigerator and the freezer are arranged along the width direction of the refrigerator 10, for example, the refrigerator can be located on the right side of the freezer; when the refrigerator and the freezer are arranged along the height direction of the refrigerator 10, for example, the refrigerator can be located above the freezer.

[0037] The door body 12 includes a shell, a cover plate, and a second heat-insulating layer. When the door body 12 is in a closed state, the cover plate faces the refrigerating compartment 1111 and closes the access opening 1112 of the refrigerating compartment 1111. The shell can be connected to the side of the cover plate facing away from the refrigerating compartment 1111 to form the appearance of the refrigerator 10. The second heat-insulating layer can be filled between the shell and the cover plate to block the heat transfer between the refrigerating compartment 1111 and the external space of the door body 12 when the door body 12 is closed. Optionally, the second heat-insulating layer is made of various heat-insulating materials including but not limited to polyurethane or heat-insulating cotton.

[0038] For example, the door body 12 is connected to the box body 11 through a hinge assembly (not shown in the drawings), so that the door body 12 can rotate relative to the box body 11, thereby opening or closing the access opening 1112 of the refrigeration chamber 1111. When the door body 12 is opened, the user can put in or take out items through the access opening 1112. When the door body 12 is closed, the items can be placed in the refrigeration chamber 1111 for low-temperature storage.

[0039] The number of door bodies 12 is set corresponding to the number of refrigeration compartments 1111. Figure 1 As shown, the box body 11 is constructed with two refrigeration compartments 1111, and the two refrigeration compartments 1111 can be arranged along the width direction of the refrigerator 10. Among them, the refrigeration compartment 1111 located on the left side of the refrigerator 10 is, for example, a freezer, and can be provided with one door body 12 or two door bodies 12. When the refrigeration compartment 1111 corresponding to the left side of the refrigerator 10 is one door body 12, it is called a single-door refrigerator 10; when the refrigeration compartment 1111 corresponding to the left side of the refrigerator 10 is two door bodies 12, it is called a double-door refrigerator 10, and the two door bodies 12 can be rotatably connected to the box body 11 on opposite sides in the horizontal direction. The two door bodies 12 can rotate in opposite directions relative to the box body 11 to open or close the refrigeration compartment 1111 located above.

[0040] For example, the refrigeration compartment 1111 located on the right side of the refrigerator 10 is set as a cold storage compartment, which can also be set as a single-door form or a double-door form, which is not limited here. Two drawers can be correspondingly arranged below the cold storage compartment, for example. The two drawers can be vertically arranged in the refrigeration compartment 1111 located below the refrigerator 10. The two drawers can be slidably connected to the box body 11 on opposite sides in the horizontal direction through a guide rail pair. The two drawers can slide relative to the box body 11. The user can pull the drawer out of the refrigeration compartment 1111, place items in the drawer, or take items out of the drawer. The user can push the drawer into the refrigeration compartment 1111 to store the items in the drawer at low temperatures.

[0041] See also Figure 2 , Figure 2The schematic diagram of the structure of the refrigeration system in the refrigerator 10 provided in the embodiment of the present disclosure is used to provide cooling capacity for the refrigeration compartment 1111. Optionally, the refrigeration system includes a compressor 101, an evaporator 102, a drying filter (not shown in the figure), a capillary 103, a condenser 104 and a gas-liquid separator (not shown in the figure). The working process of the refrigeration system includes a compression process, a condensation process, a throttling process and an evaporation process. Among them, the compression process is: plug in the power cord of the refrigerator 10, when the contacts of the thermostat are connected, the compressor 101 starts to work, and the low-temperature and low-pressure refrigerant is sucked into the compressor 101, and is compressed into a high-temperature and high-pressure superheated gas in the cylinder of the compressor 101 and then discharged into the condenser 104; the condensation process is: the high-temperature and high-pressure refrigerant gas dissipates heat through the condenser 104, the temperature continues to drop, and is gradually cooled to a saturated vapor of normal temperature and high pressure, and is further cooled to a saturated liquid, and the temperature no longer drops. The temperature at this time is called the condensation temperature, and the pressure of the refrigerant remains almost unchanged during the entire condensation process; the throttling process is: after the condenser 104 is cooled, the refrigerant gas is cooled to a high temperature and high pressure. The condensed refrigerant saturated liquid is filtered out of moisture and impurities by a drying filter and then flows into the capillary 103, through which throttling and pressure reduction are performed, and the refrigerant becomes wet steam at room temperature and low pressure; the evaporation process is as follows: the wet steam at room temperature and low pressure begins to absorb heat and vaporize in the evaporator 102, which not only reduces the temperature of the evaporator 102 and its surroundings, but also turns the refrigerant into a low-temperature, low-pressure gas; the refrigerant coming out of the evaporator 102 passes through the gas-liquid separator and then returns to the compressor 101, and the above process is repeated to transfer the heat in the refrigeration compartment 1111 of the refrigerator 10 to the air outside the cabinet 11, thereby achieving the purpose of refrigeration.

[0042] See also Figure 3 and Figure 4 The refrigeration system also includes an air duct and a fan. The refrigeration room 1111 is provided with an air outlet 1113 and an air return port 1114, and the air outlet 1113 and the air return port 1114 are both connected to the air duct, so that the air duct and the refrigeration room 1111 form a circulation flow channel. The evaporator 102 and the fan are both arranged in the air duct, and the fan provides power so that the airflow inside the refrigeration room 1111 enters the air duct through the air return port 1114 and exchanges heat with the evaporator 102 when passing through the evaporator 102, thereby reducing the airflow temperature, and the reduced airflow passes through the air outlet 1113 into the interior of the refrigeration room 1111.

[0043] For example, the air outlet 1113 is arranged on the top wall of the inner liner 111 and / or the rear wall 1116. The rear wall 1116 of the inner liner 111 refers to the side wall of the inner liner 111 facing the access opening 1112. When the air outlet 1113 is arranged on the top wall of the inner liner 111, the cold air enters the inner liner 111 from the top of the inner liner 111 downward, which can improve the uniformity of the air supply volume inside the refrigeration compartment 1111; when the air outlet 1113 is arranged on the rear wall 1116 of the inner liner 111, the air outlet 1113 is specifically arranged, for example, in the middle part or the upper part of the rear wall 1116 of the inner liner 111, which can help improve the uniformity of the cold air inside the refrigeration compartment 1111.

[0044] The return air outlet 1114 can be arranged on the top wall of the inner liner 111, on the side wall of the inner liner 111, or on the bottom wall of the inner liner 111. It can be flexibly adjusted and arranged according to actual needs and is not limited here.

[0045] Optionally, the number of air outlets 1113 and air return outlets 1114 are independently set, including but not limited to 1 or more, which can be flexibly adjusted and set according to actual needs and are not limited here.

[0046] Please continue reading Figure 3 and Figure 4 The refrigerator 10 in this embodiment further includes a shelf 13. The shelf 13 is arranged inside the refrigeration compartment 1111, specifically, for example, inside the refrigerator compartment. The shelf 13 can be used to place various items such as beverages or food.

[0047] The shelf 13 is connected to the liner 111. Specifically, the left and right opposite sides of the shelf 13 are respectively connected to the left and right opposite sides of the inner wall of the liner 111, so that the liner 111 forms a stable support for the shelf 13. Optionally, the left and right opposite sides of the inner wall of the liner 111 are both provided with mounting parts 1115, and the mounting parts 1115 can be formed integrally on the inner wall of the liner 111 by blistering, or can be formed on the inner wall of the liner 111 by bonding. The left and right opposite sides of the shelf 13 are respectively mounted on the mounting parts 1115. The mounting part 1115 is provided with a slot, for example, and the shelf 13 is detachably mounted on the mounting part 1115 by plugging. When the shelf 13 is inserted into the mounting portion 1115, the shelf 13 is also fixed to the mounting portion 1115 by, for example, a snap-fitting method to prevent the shelf 13 from being easily pulled out of the inner liner 111, thereby improving the installation stability of the shelf 13 on the inner liner 111.

[0048] See also Figure 5 and Figure 6A ventilation gap 114 is formed between the rear side of the shelf 13 and the inner container 111. Thus, when the refrigerator 10 is in use, the cold air inside the refrigerating chamber 1111 can not only flow from top to bottom through the ventilation flow passage between the shelf 13 and the door body 12, but also flow from top to bottom through the ventilation gap 114, thereby improving the uniformity of the air supply volume at each position inside the refrigerating chamber 1111.

[0049] See also Figures 5 to 7 The refrigerator 10 in this embodiment further includes an air volume adjustment mechanism 14. The air volume adjustment mechanism 14 can be connected to the shelf 13, to the inner container 111, or to the shelf 13 and the inner container 111. In this embodiment, the air volume adjustment mechanism 14 is specifically connected to the shelf 13, which is more convenient and reliable to install and operate than being connected to the inner container 111.

[0050] For example, the air volume adjustment mechanism 14 is connected to the rear side of the shelf 13. The installation method of the air volume adjustment mechanism 14 on the shelf 13 includes but is not limited to being fixedly connected by fasteners such as pins, rivets or screws, and can be flexibly adjusted and set according to actual needs, which is not limited here.

[0051] The air volume adjustment mechanism 14 is located between the rear side of the shelf 13 and the inner container 111 , and the air volume adjustment mechanism 14 is used to adjust the ventilation area size at the ventilation gap 114 .

[0052] Since an air volume adjustment mechanism 14 is added between the rear side of the shelf 13 and the inner liner 111, the air volume adjustment mechanism 14 is used to adjust the ventilation area at the ventilation gap 114. In this way, the refrigerator 10 at the production site or the user's home can adjust the ventilation area at the ventilation gap 114 between the shelf 13 and the inner liner 111 according to the design requirements, ensuring the uniformity of the air supply volume at each position in the refrigeration compartment 1111, thereby improving the temperature uniformity in the refrigeration compartment 1111.

[0053] Specifically, when the ventilation gap 114 needs to be blocked from the wind, in other words, the air volume at the ventilation gap 114 needs to be reduced or even adjusted to 0, the air volume adjustment mechanism 14 is adjusted accordingly to increase the wind blocking area, thereby reducing the ventilation area at the ventilation gap 114; conversely, when it is determined that the ventilation area of ​​the ventilation gap 114 needs to be increased, or even the ventilation gap 114 does not need to be blocked from the wind, the air volume adjustment mechanism 14 is adjusted accordingly to reduce the wind blocking area, thereby increasing the ventilation area at the ventilation gap 114.

[0054] It should be noted that the number of shelves 13 is not limited to one, but may be multiple. Figure 4When a plurality of shelves 13 are provided, the plurality of shelves 13 are sequentially and spaced apart inside the refrigerating chamber 1111 along the height direction of the refrigerating chamber 1111 .

[0055] When the air outlet 1113 is disposed in the middle or upper portion of the rear wall 1116 of the inner container 111 (e.g. Figure 4 As shown in the figure, the shelves 13 may be arranged above the air outlet 1113 or below the air outlet 1113, or at least one shelf 13 may be arranged above the air outlet 1113 and the remaining shelves 13 may be arranged below the air outlet 1113.

[0056] In some embodiments, the number of shelves 13 located below the air outlet 1113 is, for example, 1, 2, 3 or any other number. Each shelf 13 located below the air outlet 1113 is provided with an air volume adjustment mechanism 14. In this way, when the cold air discharged from the air outlet 1113 flows downward through the ventilation gap 114 formed by the rear side of each shelf 13 and the inner wall of the liner 111, the air volume at each ventilation gap 114 can be adjusted by the corresponding air volume adjustment mechanism 14, and the adjustment operation is relatively flexible, thereby improving the uniformity of the air supply volume at each position inside the refrigeration compartment 1111.

[0057] After research, it was found that the amount of cold air discharged from the air outlet 1113 flowing upward is smaller than the amount of air flowing downward, that is, the amount of cold air flowing upward through the ventilation gap 114 formed by the rear side of the shelf 13 above the air outlet 1113 and the inner wall of the liner 111 is smaller. Therefore, each shelf 13 above the air outlet 1113 does not need to be provided with an air volume adjustment mechanism 14, which can simplify the device structure and reduce costs.

[0058] Of course, as some optional solutions, each shelf 13 located above the air outlet 1113 can also be equipped with an air volume adjustment mechanism 14, which can be specifically set according to actual needs and is not limited here. Specifically, each shelf 13 inside the refrigeration compartment 1111 is equipped with an air volume adjustment mechanism 14. More specifically, multiple air volume adjustment mechanisms 14 are respectively correspondingly arranged on multiple shelves 13.

[0059] In some embodiments, when the air outlet 1113 is disposed on the top wall of the inner liner 111, an air volume adjustment mechanism 14 is disposed on each shelf 13 inside the refrigeration compartment 1111. In this arrangement, the cold air at the air outlet 1113 on the top wall of the inner liner 111 enters the refrigeration compartment 1111 from top to bottom, and when flowing through each ventilation gap 114 formed by the cooperation of each shelf 13 and the rear wall 1116 of the inner liner 111, the air volume at each ventilation gap 114 can be adjusted by the corresponding air volume adjustment mechanism 14, thereby improving the uniformity of the air supply volume at each position inside the refrigeration compartment 1111.

[0060] As an example, the number of air volume adjustment mechanisms 14 provided on one shelf 13 is, for example, one. The air volume adjustment mechanism 14 extends from the left side of the shelf 13 to the right side of the shelf 13 along the width direction of the shelf 13, so that the air volume at each position of the ventilation gap 114 along the width direction of the shelf 13 can be adjusted synchronously, thereby having a better adjustment effect, and the adjustment efficiency is higher than the adjustment efficiency when multiple air volume adjustment mechanisms 14 are provided on one shelf 13.

[0061] As another example, the number of air volume adjustment mechanisms 14 provided on one shelf 13 may be multiple, for example, 2, 3, 4 or any other number, which is not limited here. Further, multiple air volume adjustment mechanisms 14 on one shelf 13 are arranged in sequence along the width direction of the shelf 13. In this way, the air volume at each position of the ventilation gap 114 along the width direction of the shelf 13 can be adjusted independently, and the adjustment operation is more flexible.

[0062] See also Figures 6 to 9 In some embodiments, the air volume adjustment mechanism 14 includes a windshield 141. The windshield 141 includes but is not limited to a windshield plate, a windshield sheet, or a windshield block, etc., and can be flexibly adjusted and set according to actual needs. In this embodiment, the windshield 141 is specifically a windshield sheet. Optionally, the windshield sheet extends from the left side of the shelf 13 to the right side along the width direction of the shelf 13.

[0063] See also Figure 6 , Figure 7 and Fig. 9 The wind shield 141 is movably disposed on the shelf 13, for example, at the rear side of the shelf 13. The wind shield 141 has an open position (such as Figure 6 ) and the closed position (as shown Figure 7 As shown in FIG. 1 ), the air volume of the ventilation gap 114 can be infinitely adjusted between the open position and the closed position. In this way, the air volume of the ventilation gap 114 can be infinitely adjusted, thereby improving the uniformity of the air volume inside the refrigeration compartment 1111, and having a better adjustment effect.

[0064] See also Figure 7 and Fig. 9 When the wind shield 141 is in the closed position, the wind shield 141 protrudes from the rear side of the shelf 13 toward the rear wall 1116 of the inner tank 111 to the ventilation gap 114, thereby blocking the cold air in the ventilation gap 114 and effectively reducing the cold air flow passing through the ventilation gap 114.

[0065] See also Figure 6 and Fig. 9Specifically, when the wind shield 141 is in the open position, the distance between the wind shield 141 and the rear wall 1116 of the inner liner 111 is set to a first distance; when the wind shield 141 is in the closed position, the distance between the wind shield 141 and the rear wall 1116 of the inner liner 111 is set to a second distance. The first distance is greater than the second distance. In this way, when the wind shield 141 is adjusted from the open position to the closed position, the distance between the wind shield 141 and the rear wall 1116 of the inner liner 111 gradually decreases, so that the air volume at the ventilation gap 114 gradually decreases until it decreases to 0, that is, the second distance is 0; conversely, when the wind shield 141 is adjusted from the closed position to the open position, the distance between the wind shield 141 and the rear wall 1116 of the inner liner 111 gradually increases, so that the air volume at the ventilation gap 114 gradually increases, until the ventilation gap 114 is completely unblocked by the wind shield 141.

[0066] See also Figure 6 When the wind shield 141 is in the open position, the projection of the wind shield 141 in the direction perpendicular to the thickness of the shelf 13 is completely located on the shelf 13. In other words, the wind shield 141 does not protrude into the ventilation gap 114, and does not block the air volume at the ventilation gap 114, thereby achieving the adjustment of the air volume at the ventilation gap 114 to the maximum.

[0067] It should be noted that the wind shield 141 can be rotatably arranged on the shelf 13, or can be movably arranged on the shelf 13 along the front-to-back direction of the refrigeration chamber 1111, or can be arranged on the shelf 13 in other ways, as long as the position on the shelf 13 can be adjusted, so that the size of the shielding area of ​​the ventilation gap 114 can be adjusted.

[0068] In this embodiment, the windshield 141 is specifically arranged on the shelf 13 in a rotating manner. In this arrangement, since the size of the ventilation gap 114 is relatively reduced, the distance between the windshield 141 and the inner wall of the liner 111 is adjusted accordingly by adjusting the rotation angle of the windshield 141. Compared with adjusting the position of the windshield 141 by moving it in the front-back direction, the position of the windshield 141 can be adjusted more accurately, that is, the distance between the windshield 141 and the inner wall of the liner 111 can be controlled more accurately, so that the air volume at the ventilation gap 114 can be accurately adjusted.

[0069] See also Figure 6 , Figure 7 and Fig. 9On the basis of the above-mentioned embodiment, the air volume adjustment mechanism 14 further includes a mounting frame 142. The mounting frame 142 is mounted on the rear side of the shelf 13. Specifically, the mounting frame 142 includes but is not limited to being connected to the shelf 13 by snap-fitting, bonding, or fasteners such as pins, rivets, screws, or screws. In this embodiment, the mounting frame 142 is detachably mounted on the shelf 13 by snap-fitting, for example, so that the assembly efficiency is high and the disassembly and assembly operation is convenient.

[0070] The mounting frame 142 is, for example, a decorative piece, which is installed on the rear side of the shelf 13 to play a decorative role and has a better appearance. In addition, the mounting frame 142 extends from the left side of the shelf 13 to the right side of the shelf 13, for example.

[0071] On the basis of the above-mentioned embodiment, the windshield 141 is specifically rotatably arranged on the mounting frame 142. In this way, the windshield 141 is indirectly mounted on the rear side of the shelf 13. Compared with the method of directly and rotatably mounting the windshield 141 on the rear side of the shelf 13, since the windshield 141 and the mounting frame 142 can be assembled, and then the mounting frame 142 can be mounted on the rear side of the shelf 13, for example, by snapping, there is no effect on the structure of the rear side of the shelf 13 itself, thereby not only improving the assembly efficiency, but also avoiding damage to the rear side of the shelf 13.

[0072] See also Figure 6 , Figure 7 and Fig. 9 In some embodiments, the air volume adjustment mechanism 14 further includes a rotating arm 143. The rotating arm 143 is connected between the mounting frame 142 and the wind shield 141, and the opposite ends of the rotating arm 143 are respectively rotatably connected to the mounting frame 142 and the wind shield 141. In this way, the rotating arm 143 plays a role in connecting the wind shield 141 and the mounting frame 142. By moving the wind shield 141, the wind shield 141 swings relative to the mounting frame 142, thereby adjusting the air volume at the ventilation gap 114.

[0073] In some embodiments, a fixing seat 1421 is provided on the mounting frame 142, and the rotating arm 143 is rotatably connected to the fixing seat 1421. The "fixing seat 1421" in this embodiment can be "a part of the mounting frame 142", that is, the "fixing seat 1421" and the "other parts of the mounting frame 142" are integrally formed and manufactured; or it can be an independent component that can be separated from the "other parts of the mounting frame 142", that is, the "fixing seat 1421" can be manufactured independently and then combined with the "other parts of the mounting frame 142" into a whole.

[0074] See also Figures 9 to 11In some embodiments, the air volume adjustment mechanism 14 further includes a locking member 144. The locking member 144 is connected to the fixing seat 1421, and the locking member 144 is provided with a locking position and an unlocking position. When the locking member 144 is switched to the locking position, the locking member 144 is used to lock and fix the rotating arm 143 to the fixing seat 1421; when the locking member 144 is switched to the unlocking position, the locking member 144 is used to release the lock between the rotating arm 143 and the fixing seat 1421. With such arrangement, when it is necessary to adjust the front and rear position of the wind shield 141 by rotating the rotating arm 143, the locking member 144 is first switched to the unlocking position, and the locking member 144 correspondingly releases the lock between the rotating arm 143 and the fixing seat 1421, so that when the wind shield 141 is subjected to an external force, the rotating arm 143 can rotate relative to the fixing seat 1421, and the wind shield 141 can be adjusted to the target position; when the wind shield 141 is adjusted to the target position, the unlocking member is switched to the locking position, and the locking member 144 correspondingly locks the rotating arm 143 to the fixing seat 1421, thereby preventing the wind shield 141 from position shifting under the action of an external force, thereby ensuring the accuracy of the position of the wind shield 141 and improving the installation reliability.

[0075] In addition, the mounting frame 142 is specifically assembled on the rear side of the shelf 13 by a snap-fitting method, the fixing seat 1421 is integrally arranged on the mounting frame 142, and the rotating arm 143 is connected to the fixing seat 1421 by a rotating method. It can be seen that it is only necessary to set the air volume adjustment mechanism 14 on the rear side of the shelf 13 in the related art, which has a simple structure, strong versatility, and does not require screws, making it easy to disassemble and assemble, saving time and effort.

[0076] It should be noted that there are many specific structural forms of the locking member 144. For example, a knob 1441 is used, and the locking fit or unlocking between the rotating arm 143 and the fixed seat 1421 is achieved by rotating the knob 1441 to a locking position or a locking position. For another example, a tightening screw is used, and the locking fit or unlocking between the rotating arm 143 and the fixed seat 1421 is achieved by rotating the locking screw to a locking position or a locking position. Other structural forms can also be used, which can be flexibly adjusted according to actual needs and are not limited here.

[0077] In this embodiment, in order to improve the operational convenience and installation reliability, the locking member 144 specifically adopts the structure of a knob 1441, and the locking or unlocking between the rotating arm 143 and the fixing seat 1421 is achieved by adjusting the rotation position.

[0078] See also Figures 9 to 11In a specific embodiment, the fixing seat 1421 includes at least two split parts 1422, which are arranged in sequence around the central axis of the fixing seat 1421. The at least two split parts 1422 also enclose an insertion hole 1423, and the sides of two adjacent split parts 1422 cooperate to form an avoidance gap 1424. Specifically, during production and processing, for example, the fixing seat 1421 is cut along the central axis of the fixing seat 1421, so that the fixing seat 1421 forms at least two split parts 1422, and the avoidance gap 1424 is formed at the same time.

[0079] As an example, when there are two split parts 1422, the two avoidance gaps 1424 on the fixing seat 1421 are set as a straight-line gap. When there are four split parts 1422, the four avoidance gaps 1424 on the fixing seat 1421 are set as a cross-shaped gap. Of course, the split parts 1422 can also be set to three or other larger numbers, which is not limited here.

[0080] The rotating arm 143 defines a first rotating hole 1431 , and all the body parts 1422 are inserted into the first rotating hole 1431 .

[0081] For example, the locking member 144 includes a knob 1441 and an insertion rod 1442. The knob 1441 is rotatably mounted on the fixing seat 1421. The knob 1441 mounted on the fixing seat 1421 can be easily rotated, while ensuring the product is beautiful and has high installation reliability. The insertion rod 1442 is connected to the knob 1441, and a protrusion 1443 is provided on the outer wall of the insertion rod 1442. The insertion rod 1442 is rotatably inserted into the insertion hole 1423. When rotating, the insertion rod 1442 can be driven to rotate and adjust the position accordingly.

[0082] See also Figures 9 to 11 When the knob 1441 is rotated to the locking position, the protrusion 1443 abuts against the split portion 1422, and the protrusion 1443 can push the split portion 1422 toward the outside, so that the split portion 1422 and the rotating arm 143 are locked and fixed, and the rotating arm 143 is locked and fixed on the fixing seat 1421, thereby achieving the position fixation of the wind shield 141; when the knob 1441 is rotated to the unlocking position, the protrusion 1443 is located in the avoidance gap 1424, and the split portion 1422 is reset under the action of its own elastic force, and the split portion 1422 is not tightly abutted against the inner wall of the first rotating hole 1431 of the rotating arm 143, so that the split portion 1422 and the rotating arm 143 are unlocked, so that the rotating arm 143 can rotate freely relative to the fixing seat 1421, so that the position of the wind shield 141 can be adjusted along the front and rear directions.

[0083] Among them, the rotation angle of the knob 1441 from the unlocked position to the locked position is, for example, 30°, 45°, 60°, 90°, 120° or 150°, etc., which can be flexibly adjusted and set according to actual needs and is not limited here.

[0084] Optionally, the number of protrusions 1443 can be one or more. For example, the number of protrusions 1443 is 2, 3 or other larger numbers. In this embodiment, the number of protrusions 1443 is the same as the number of split parts 1422 and is arranged one by one. In this way, when the knob 1441 is rotated to the locked position, each protrusion 1443 is respectively in contact with each split part 1422, so that each split part 1422 is pushed open, thereby effectively locking and fixing the rotating arm 143. In addition, when the knob 1441 is rotated to the unlocked position, each protrusion 1443 is respectively arranged in each avoidance gap 1424.

[0085] In some embodiments, a stopper 1425 is provided on the outer wall of the split portion 1422, and the rotating arm 143 abuts against the stopper 1425 along the central axis direction of the fixing seat 1421. The stopper 1425 is provided with a guide slope 14251, which is arranged at an angle with the central axis direction, and the distance between the guide slope 14251 and the central axis increases along the direction close to the mounting frame 142.

[0086] It should be noted that the central axis of the fixing seat 1421 is the Z dotted line shown in the figure.

[0087] With such arrangement, on the one hand, the limiting portion 1425 abuts and cooperates with the rotating arm 143 along the central axis direction of the fixing seat 1421, thereby limiting the rotating arm 143 and preventing the rotating arm 143 from detaching from the fixing seat 1421, thereby improving the installation stability and reliability of the rotating arm 143 on the fixing seat 1421; on the other hand, since the limiting portion 1425 is provided with a guiding slope 14251, the guiding slope 14251 is arranged at an angle to the central axis direction, and the distance between the guiding slope 14251 and the central axis tends to increase in the direction close to the mounting frame 142, so that the guiding slope 14251 plays a guiding role, which can facilitate the rotating arm 143 to be directly installed on the fixing seat 1421 by means of insertion, and at the same time, there is no need to use fasteners such as screws or pins, and the assembly operation is more convenient and reliable.

[0088] In one embodiment, the number of rotating arms 143 is multiple, and the multiple rotating arms 143 are sequentially spaced apart along the width direction of the mounting frame 142. In this way, the windshield 141 is rotatably connected to the mounting frame 142 through the multiple rotating arms 143, so that the stability of the windshield 141 on the mounting frame 142 is enhanced.

[0089] Correspondingly, there are multiple fixing seats 1421 and locking members 144, and each fixing seat 1421 is disposed correspondingly to each rotating arm 143. Each locking member 144 is disposed correspondingly to each fixing seat 1421.

[0090] In one embodiment, the rotating arm 143 is provided with a rotating shaft 1432, and the wind shield 141 is provided with a second rotating hole 1411, and the rotating shaft 1432 is rotatably inserted into the second rotating hole 1411. Specifically, the second rotating hole 1411 is provided in plurality, and the plurality of second rotating holes 1411 are provided in a one-to-one correspondence with the plurality of rotating shafts 1432 of the rotating arms 143.

[0091] It should be noted that, the "rotating shaft 1432" in this embodiment can be "a part of the rotating arm 143", that is, the "rotating shaft 1432" and the "other parts of the rotating arm 143" are manufactured as one piece; it can also be an independent component separable from the "other parts of the rotating arm 143", that is, the "rotating shaft 1432" can be manufactured independently and then combined with the "other parts of the rotating arm 143" into a whole.
