[0058] The refrigeration equipment in the present application generally includes a cabinet, a door body and a refrigeration system, wherein at least a refrigeration chamber is formed in the cabinet, and the refrigeration chamber is opened and closed through the door body to meet the requirements of accessing articles.

[0059] The refrigeration system performs a refrigeration cycle of the refrigeration equipment by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to achieve refrigeration of articles in the cabinet.

[0060] The low-temperature and low-pressure refrigerant enters the compressor, which compresses the refrigerant gas into a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0061] The expansion valve expands the high-temperature and high-pressure liquid phase refrigerant formed in the condenser into a low-pressure liquid phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can cool the articles in the cabinet by utilizing the latent heat of evaporation of the refrigerant.

[0062] Reference Figure 1 、 Figure 2 The present application provides a refrigeration equipment, which comprises a cabinet 100, a cabinet door and a return air valve group 200, and the cabinet 100 is formed with a first chamber 101, a second chamber 102 and a machine compartment 103.

[0063] The cabinet 100 specifically comprises an outer shell 110, a first inner container 120 and a second inner container 130, the first inner container 120 is located above the second inner container 130, the first chamber 101 is formed in the first inner container 120, and the second chamber 102 is formed in the second inner container 130,

[0064] A plurality of shelves 140 are arranged in the first chamber 101 and the second chamber 102 along the height direction, respectively, for placing articles.

[0065] At least a heat exchanger and a fan are arranged in the machine chamber 103, the heat exchanger is an evaporator, under the driving of the fan, the airflow exchanges heat in the heat exchanger to form low-temperature airflow, which is separately delivered into the second chamber 102 or delivered into the first chamber 101 and the second chamber 102.

[0066] The box door is connected to the front side of the box body 100, and is used to open or close the first chamber 101 and the second chamber 102.

[0067] The second chamber 102 is a refrigeration chamber, and the first chamber 101 can be set as a warm-keeping chamber or a refrigeration chamber according to the actual needs of the user.

[0068] When the first chamber 101 is used as a warm-keeping chamber, it separately delivers the airflow after heating into the warm-keeping chamber through a set of heat exchange systems, and forms an independent circulation in the warm-keeping chamber to realize the heating mode of the first chamber 101.

[0069] The heating mode can be realized by a separate heating plate, or the airflow can be separately delivered to the condenser for heat exchange, and the high-temperature airflow after heating by the heating plate or heat exchange with the condenser is delivered into the first chamber 101 to realize the heating treatment of the first chamber 101.

[0070] The specific implementation mode of the first chamber 101 when used as a warm-keeping chamber is a prior art, and is not the design focus of the present application, which is not described here.

[0071] Specifically, the first chamber 101 is located above the second chamber 102, and a heat insulation gap is formed between the second chamber 102 and the first chamber 101, and a heat insulation layer can be arranged in the heat insulation gap to reduce the heat exchange between the second chamber 102 and the first chamber 101.

[0072] The return air valve group 200 is arranged between the first chamber 101 and the second chamber 102, and is located close to the box door, that is, the return air valve group 200 is arranged at the front position of the second chamber 102 and the first chamber 101.

[0073] Reference Figures 3-5 The return air valve group 200 includes a driving part 210 and a valve body part, the driving part 210 is fixed in the box body 100, the valve body part is connected with the output end of the driving part 210, and the valve body part is used to control the on-off between the first chamber 101 and the second chamber 102.

[0074] Specifically, the bottom of the first chamber 101 and the bottom of the second chamber 102 are provided with air passages, and the return air valve group 200 is arranged between the two air passages to control the on-off of the two air passages.

[0075] The overwind opening on the first chamber 101 is defined as an upper overwind opening, the overwind opening on the second chamber 102 is defined as a lower overwind opening 132, and an overwind passage is formed between the upper overwind opening and the lower overwind opening 132. The return air valve group 200 is arranged in the overwind passage.

[0076] In some embodiments of the present application, the overwind passage is configured to, when the return air valve group 200 is opened, output the air flow from the upper overwind opening to the second chamber 102 through the lower overwind opening 132.

[0077] The refrigeration equipment further comprises a controller connected with the return air valve group 200. The controller is configured to control the return air valve group 200 to be in a closed state when the first chamber 101 is used as a warm-keeping chamber, and control the return air valve group 200 to be in an opened state when the first chamber 101 is used as a refrigeration chamber.

[0078] In some embodiments of the present application, the upper overwind opening and the lower overwind opening 132 are both openings extending along the width direction of the cabinet 100, so as to improve the ventilation effect.

[0079] The valve body part comprises a first valve body 230 and a second valve body 240. The first valve body 230 and the second valve body 240 both extend along the length direction of the overwind opening. The length direction of the overwind opening is defined as the same as the width direction of the cabinet 100, and the width direction of the overwind opening is defined as the same as the depth direction of the cabinet 100.

[0080] The driving part 210 is fixed in the overwind passage through a support, and specifically, the driving part 210 can be supported on the top wall of the second chamber 102.

[0081] The output end of the driving part 210 is rotatably connected with the first valve body 230 and the second valve body 240 through the adapter 220. The first valve body 230 is provided with a first contact surface 231, and the second valve body 240 is provided with a second contact surface 241. The first contact surface 231 and the second contact surface 241 are respectively arranged in an inclined manner and are in contact connection.

[0082] The driving part 210 drives the first valve body 230 and the second valve body 240 to form a relative movement. During the relative movement of the first valve body 230 and the second valve body 240, the first valve body 230 and the second valve body 240 are close to or away from each other under the limitation of the first contact surface 231 and the second contact surface 241, so as to change the overall width dimension of the valve body part.

[0083] In combination with Figure 6 , Figure 7 and Figure 10 , when the return air valve group 200 is in a closed state, the width L1 of the valve body part is equal to the width of the overwind opening d, so as to close the overwind opening.

[0084] When the return air valve assembly 200 is opened, the driving unit 210 drives the first valve body 230 and the second valve body 240 to move in a direction close to each other, and the overall width of the valve body becomes L2, wherein L2 <L1,将过风口部分暴露。

[0085] Combine Figure 8 、 Figure 9 In some embodiments of the present application, a first sealing surface 233 is further provided on the first valve body 230, and the first sealing surface 233 is located on both sides of the first contact surface 231. A second sealing surface 243 is also provided on the second valve body 240, and the second sealing surface 243 is located on both sides of the second contact surface 241. When the return air valve group 200 is in the closed state, the first sealing surface 233 contacts the second sealing surface 243 on the corresponding side, thereby improving the sealing effect between the first valve body 230 and the second valve body 240.

[0086] In order to provide stable drive for the movement of the first valve body 230 and the second valve body 240 during the switching process of the return air valve group 200, in some embodiments of the present application, a driving part 210 is respectively provided at both ends of the air outlet along the length direction of the air outlet, and each driving part 210 is hinged to the two ends of the first valve body 230 and the second valve body 240 through the adapter part 220.

[0087] The two driving parts 210 are connected to the controller signal. The controller controls the driving parts 210 to switch synchronously, thereby providing a consistent force to both ends of the first valve body 230 and the second valve body 240 .

[0088] In some embodiments of the present application, the adapter portion 220 may be designed as a disc structure, and the ends of the first valve body 230 and the second valve body 240 are rotatably connected to the end surface of the adapter portion 220 via a rotating shaft.

[0089] Reference again Figure 5 In other embodiments, in order to reduce the weight of the adapter 220 and reduce manufacturing costs, a first protrusion 221 and a second protrusion 222 extending outward away from the direction of the rotation center are formed on the adapter 220, and the adapter 220 is connected to the first valve body 230 and the second valve body 240 through the first protrusion 221 and the second protrusion 222.

[0090] A first connecting portion 2211 is formed on the first protrusion 221, a second connecting portion 2221 is formed on the second protrusion 222, first rotating portions 232 are respectively formed at both ends of the first valve body 230, and second rotating portions 242 are respectively formed at both ends of the second valve body 240. The two ends of the first valve body 230 are respectively hinged to the corresponding first connecting portion 2211 through the first rotating portion 232, and the two ends of the second valve body 240 are respectively hinged to the corresponding second connecting portion 2221 through the second rotating portion 242.

[0091] In some embodiments of the present application, the first connecting portion 2211 and the second connecting portion 2221 are connecting hole structures, the first rotating portion 232 and the second rotating portion 242 are connecting shaft structures, and the first rotating portion 232 and the second rotating portion 242 are inserted into the corresponding first connecting portion 2211 and the second connecting portion 2221 to achieve the rotatable connection of the first valve body 230, the second valve body 240 and the adapter 220.

[0092] In the attached drawings Figure 6 , the attached drawings Figure 7 , for example, during the opening process of the return air valve group 200, the driving portion 210 drives the adapter 220 to rotate clockwise, the first protrusion 221 on the adapter 220 rotates downward, and under the interaction of the first connecting portion 2211 and the first rotating portion 232, the first valve body 230 moves downward along the second contact surface 241 and partially moves into the lower air outlet 132.

[0093] Similarly, the driving portion 210 simultaneously drives the second protrusion 222 on the adapter 220 to rotate upward, and under the interaction of the second connecting portion 2221 and the second rotating portion 242, the second valve body 240 moves upward along the first contact surface 231 and partially moves into the upper air outlet.

[0094] During the closing process of the return air valve group 200, the driving portion 210 drives the adapter 220 to rotate in the opposite direction, the first protrusion 221 of the adapter 220 rotates counterclockwise, and under the interaction of the first connecting portion 2211 and the first rotating portion 232, the first valve body 230 moves upward along the second contact surface 241.

[0095] At the same time, the driving portion 210 drives the second protrusion 222 to rotate downward, and under the interaction of the second connecting portion 2221 and the second rotating portion 242, the second valve body 240 moves downward along the first contact surface 231 and moves out of the upper air outlet.

[0096] In the rotated position, the two sides of the valve body portion are in contact with the two sides of the lower air outlet 132, and the passage between the upper air outlet and the lower air outlet 132 is cut off.

[0097] The refrigeration equipment disclosed in the present application, when the second chamber 102 is used as a refrigeration chamber, the second chamber 102 and the first chamber 101 are independently operated and do not affect each other. When the second chamber 102 is used as a refrigeration chamber, in order to improve the airflow range in the second chamber 102 and improve the refrigeration cycle in the second chamber 102, the refrigeration efficiency of the front side of the second chamber 102 is higher, and the temperature is uniform, the cold exchange is sufficient, and the energy saving and power saving effect is achieved.

[0098] Again refer to Figure 1In some embodiments of the present application, the rear wall of the second inner container 130 is provided with a rear backboard 134, and a blowing passage is formed between the rear backboard 134 and the second inner container. A blowing valve group is formed between the first inner container 120 and the second inner container 130, and the blowing valve group is used to control the opening and closing of the first inner container 120 and the blowing passage.

[0099] In some embodiments of the present application, the rear backboard 134 is provided with an air outlet 135, and the air outlet 135 is used to deliver the airflow in the blowing passage to the first chamber 101.

[0100] Reference Figures 13-15 The blowing valve group and the return valve group 200 are synchronously switched, that is, when the first chamber 101 is used as a refrigeration chamber, the blowing valve group and the return valve group 200 are simultaneously opened, and the low-temperature airflow in the second chamber 102 enters the first chamber 101 through the blowing valve group, and after heat exchange in the first chamber 101, the low-temperature airflow is delivered back to the second chamber 102 through the return valve group 200, and finally delivered back to the heat exchange chamber through the return air outlet 131 at the bottom of the second chamber 102.

[0101] The blowing valve group is located at the rear side of the first inner container 120 and the second inner container 130, and the blowing valve group includes at least one blowing valve 300 arranged along the length direction of the first chamber 101.

[0102] In order to improve the blowing efficiency, the blowing valve group can include a plurality of blowing valves 300 arranged at intervals.

[0103] The bottom of the first inner container 120 and the top of the second inner container 130 are respectively provided with mounting ports matched with the number of blowing valves 300. The mounting port on the first inner container 120 is defined as an upper mounting port, and the mounting port on the second inner container 130 is defined as a lower mounting port 133.

The air outlet valve seat 310 is detachably connected to the support frame 340 . The vents 311 on each air outlet valve seat 310 are in communication with the corresponding air supply channel.

[0108] In other words, a plurality of mounting positions 341 are provided on the support frame 340, and the number of mounting positions 341 corresponds to the number of the air outlet valves 300. An air supply channel is formed on each mounting position 341. The air outlet valve body 330 realizes the opening and closing of the air supply channel by controlling the switch of the vent 311 on the corresponding air outlet valve seat 310, thereby realizing the opening and closing of the first chamber 101 and the second chamber 102.

[0109] In some embodiments of the present application, a snap-fit ​​portion 342 is formed on the upper support portion 345, and the snap-fit ​​portion 342 is arranged on the peripheral side of the air supply channel.

[0111] Combine Figure 1 、 Figure 2 The present application also proposes a refrigeration device, which includes a box body 100, a box door and a return air valve group 200. A first chamber 101, a second chamber 102 and a machine compartment 103 are formed in the box body 100. A fan is installed in the machine compartment 103, and the second chamber 102 is a refrigeration chamber.

[0112] The door is connected to the box body 100 and is used to open or close the second chamber 102 and the first chamber 101 .

[0113] The return air valve group 200 is arranged between the second chamber 102 and the first chamber 101 and located at the front side close to the cabinet door. When the first chamber 101 is used as a refrigeration chamber, the return air valve group 200 separates the second chamber 102 and the first chamber 101. When the first chamber 101 is used as a refrigeration chamber, the return air valve group 200 connects the second chamber 102 and the first chamber 101, so that the refrigeration air flow input from the rear side of the second chamber 102 is transported to the first chamber 101 through the return air valve group 200, and is returned to the machine room 103 from the return air outlet 131 at the bottom of the first chamber 101.

[0114] The first chamber 101 is located above the second chamber 102, and a heat insulation gap is formed between the second chamber 102 and the first chamber 101 to reduce heat transfer between the first chamber 101 and the second chamber 102.

[0115] The bottom of the first chamber 101 and the top of the second chamber 102 are provided with air passing openings, and the return air valve group 200 is arranged between the two air passing openings to control the on-off of the two air passing openings.

[0116] The air passing opening on the first chamber 101 is defined as an upper air passing opening, and the air passing opening on the second chamber 102 is defined as a lower air passing opening 132. An air passing channel is formed between the upper air passing opening and the lower air passing opening 132, and the return air valve group 200 is arranged in the air passing channel.

[0117] The air passing channel is used to output the air flow from the upper air passing opening to the second chamber 102 through the lower air passing opening 132 when the return air valve group 200 is opened.

[0118] The return air valve group 200 can be arranged in the following ways or in combination of some of the following ways.

[0119] In the first way, the return air valve group 200 includes a driving part 210 and a valve body part. The valve body part is a cover plate structure (not shown), the driving part 210 is fixed in the air passing channel, and the valve body part is rotatably connected to the upper air passing opening or the lower air passing opening 132. The driving part 210 controls the opening and closing of the upper air passing opening or the lower air passing opening 132 through the valve body part, thereby realizing the connection between the first chamber 101 and the second chamber 102.

[0120] The rotation center of the valve body part can be located at one side of the upper air passing opening or the lower air passing opening 132. When the valve body part is opened, it is rotated to open the air passing channel, so as to avoid affecting the storage space of the first chamber 101 or the second chamber 102.

[0121] Alternatively, the valve body can also be rotatably connected in the air passage, with its rotation center located at the center position of the valve body. Under the action of the driving part 210, the valve body flips open in the air passage to a vertical state, opening the air passage, and the valve body is closed. The driving part 210 drives the valve body to rotate to a horizontal position, closing the air passage.

[0122] Method 2, reference Figures 3-9 The return air valve group 200 includes a driving part 210 and a valve body part. The driving part 210 is fixed in the air passage. The valve body part is connected to the output end of the driving part 210. The valve body part is used to control the on-off between the first chamber 101 and the second chamber 102.

[0123] The valve body portion includes a first valve body 230 and a second valve body 240, both of which extend along the length direction of the air outlet, defining that the length direction of the air outlet is consistent with the width direction of the box body 100, and the width direction of the air outlet is consistent with the depth direction of the box body 100.

[0124] The driving unit 210 is fixed in the air passage through a bracket, and specifically, can be supported on the top wall of the second chamber 102 .

[0125] The output end of the driving part 210 is rotatably connected to the first valve body 230 and the second valve body 240 through the adapter part 220. A first contact surface 231 is formed on the first valve body 230, and a second contact surface 241 is formed on the second valve body 240. The first contact surface 231 and the second contact surface 241 are respectively arranged obliquely and in contact with each other.

[0126] The driving part 210 drives the first valve body 230 and the second valve body 240 to form relative movement. During the relative movement of the first valve body 230 and the second valve body 240, under the restriction of the first contact surface 231 and the second contact surface 241, the first valve body 230 and the second valve body 240 approach or move away from each other, so that the overall width dimension of the valve body part changes.

[0127] When the return air valve assembly 200 is in a closed state, the width of the valve body is equal to the width of the air outlet, so that the air outlet is closed.

[0128] When the return air valve assembly 200 is opened, the driving unit 210 drives the first valve body 230 and the second valve body 240 to move in a direction close to each other, and the overall width of the valve body becomes smaller, exposing the air outlet portion.

[0129] Method 3, refer again Figure 5 On the basis of the above-mentioned method 2, a first convex portion 221 and a second convex portion 222 extending outward away from the rotation center direction are formed on the adapter portion 220, and the adapter portion 220 is connected to the first valve body 230 and the second valve body 240 through the first convex portion 221 and the second convex portion 222.

[0131] In some embodiments of the present application, the first connecting part 2211 and the second connecting part 2221 are connecting hole structures, the first rotating part 232 and the second rotating part 242 are connecting shaft structures, and the first rotating part 232 and the second rotating part 242 are inserted into the corresponding first connecting part 2211 and the second connecting part 2221 to achieve the rotatable connection of the first valve body 230, the second valve body 240 and the adapter 220.

[0132] The rear wall of the second inner container 130 is provided with a rear back plate 134, a blowing passage is formed between the rear back plate 134 and the second inner container, and an air outlet valve group is formed between the first inner container 120 and the second inner container 130, which is used to control the on-off of the first inner container 120 and the blowing passage.

[0133] In some embodiments of the present application, the rear back plate 134 is provided with an air outlet 135, which is used to deliver the airflow in the blowing passage to the first chamber 101.

[0134] The air outlet valve group and the return air valve group 200 are synchronously opened and closed, that is, when the first chamber 101 is used as a refrigeration chamber, the air outlet valve group and the return air valve group 200 are simultaneously opened, the low-temperature airflow in the second chamber 102 enters the first chamber 101 through the air outlet valve group, is heated in the first chamber 101, is delivered back to the second chamber 102 through the return air valve group 200, and finally is delivered back to the heat exchange chamber through the return air outlet 131 at the bottom of the second chamber 102.

[0135] The above three modes can be used alone or in combination.

[0136] As far as possible, various aspects and features described and shown in the specification can be applied alone, and these individual aspects can be the subject of a divisional application.

[0137] In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0138] The above merely is the specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, and all should be covered in the protection scope of the present application.
