Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, and more specifically to a gas distribution device for refrigeration equipment and refrigeration equipment. Background Technology

[0002] Refrigeration equipment refers to equipment primarily used for refrigerating food for crew members, refrigerating various types of cargo, and conditioning cabin air during hot weather. It mainly consists of a compressor, expansion valve, evaporator, condenser, accessories, and piping. Based on their working principle, they can be classified into compression refrigeration equipment, absorption refrigeration equipment, vapor jet refrigeration equipment, heat pump refrigeration equipment, and electric heating refrigeration devices, etc.

[0003] Taking a refrigerator as an example, a refrigerator is usually equipped with a refrigerator compartment and a freezer compartment. The refrigerator compartment is equipped with a refrigerator air duct and an air outlet. In addition, the freezer compartment is equipped with a freezer air duct. Cold air is usually sent from the freezer air duct to the refrigerator air duct, and then blown into the refrigerator compartment through the air outlet of the refrigerator air duct.

[0004] Since the refrigeration air duct is usually designed at the back of the refrigerator, and users often place food on the glass shelves in front of the refrigeration air duct, the air outlet of the refrigeration air duct can easily be blocked. This can cause food near the air outlet to become too cold and easily freeze or lose moisture due to prolonged exposure to airflow, while food far from the air outlet is prone to spoilage due to insufficient cooling. Summary of the Invention

[0005] The purpose of this invention is to provide a gas distribution device for refrigeration equipment, the gas distribution device having a gas distribution body, wherein the gas distribution body is provided with an air duct that can guide cold air in the cold air channel to a portion of the refrigeration chamber away from the cold air channel, thereby guiding cold air into the refrigeration chamber even if the air outlet of the cold air channel is blocked, so that the refrigeration chamber can maintain the required refrigeration temperature.

[0008] The above technical solution, by setting up a gas distribution device that can be installed in the refrigeration chamber, can guide cold air to the part of the refrigeration chamber away from the cold air duct. In this way, even if the air outlet of the cold air duct is blocked by the stored food, cold air can still be blown into the refrigeration chamber, thereby making the temperature in the refrigeration chamber more uniform and stable, and maintaining the temperature required for food storage, which is beneficial for food storage.

Detailed Implementation

[0040] In this invention, unless otherwise stated, directional terms such as "up," "down," "left," and "right" are generally understood in conjunction with the accompanying drawings and the orientation shown in actual application, while "inner" and "outer" refer to the inner and outer contours of the component.

[0041] like Figure 1 As shown, the refrigeration equipment 20 is equipped with a refrigeration chamber 22, which may include a refrigerator chamber 22a and a freezer chamber 22b distributed along the height direction of the refrigeration equipment 20, and the refrigerator chamber 22a and the freezer chamber 22b are separated from each other; the refrigeration chamber 22 has a cold air duct 220 extending along the height direction of the refrigeration chamber 22 and through which cold air passes, the cold air duct 220 may include a refrigerator air duct 220a and a freezer air duct 220b connected to the refrigerator air duct 220a, wherein the refrigerator air duct 220a is disposed in the refrigerator chamber 22a and can extend along the height direction of the refrigerator chamber 22a, and the freezer air duct 220b can be disposed in the freezer chamber 22b, and the freezer air duct 220b is connected to the refrigerator air duct 22a. The air ducts 220a are interconnected, and the freezing air duct 220b can extend along the height of the freezing chamber 22b. Cold air can be blown from the freezing air duct 220b to the refrigeration air duct 220a. Air outlets 220c can be provided on the wall of the cold air duct 220 facing the refrigeration chamber 22, so that cold air can be blown to the refrigeration chamber 22a or the freezing chamber 22b accordingly. Preferably, multiple air outlets 220c can be provided, and the multiple air outlets 220c can be arranged along the extension direction of the cold air duct 220. In addition, the refrigeration equipment 20 may include a door 24 for closing the refrigeration chamber 22. The door 24 may include a refrigeration door 24a for closing the refrigeration chamber 22a and a freezing door 24b for closing the freezing chamber 22b. Figure 1 and Figure 14 As shown, a bottle rack 26 can be installed in the refrigerator compartment 22a, and the bottle rack 26 can be installed in the refrigerator door 24a; in addition, combined with Figure 10 and Figure 11 As shown, the refrigerator compartment 22a may be provided with a support boss 28 for components such as the gas distribution device 10. The support boss 28 may extend in a direction perpendicular to the height direction of the refrigerator compartment 22a, for example, it may extend in the depth direction of the refrigerator compartment 22. The gas distribution device 10 will be described in detail below and will not be repeated here. The refrigeration equipment 20 may include a refrigerator, such as a single-door refrigerator, a multi-door refrigerator, or a side-by-side refrigerator.

[0042] This invention provides a gas distribution device 10 for refrigeration equipment. The gas distribution device 10 can be installed inside a refrigeration chamber 22, for example, inside a refrigerator compartment 22a. The gas distribution device 10 includes a gas distribution body 12, within which an air duct 120 is provided. The two ends of the air duct 120 are respectively formed as an air duct inlet communicating with a cold air passage 220 and an air duct outlet capable of discharging cold air into the refrigeration chamber 22. The air duct 120 extends from the cold air passage 220 in a direction away from the cold air passage 220. By providing a gas distribution device 10 that can be installed inside the refrigeration chamber 22, cold air can be directed to the portion of the refrigeration chamber 22 away from the cold air passage 220. Thus, even if the air outlet 220c of the cold air passage 220 is blocked by stored food, cold air can still be blown into the refrigeration chamber 22, thereby making the temperature inside the refrigeration chamber 22 more uniform and stable, and maintaining the temperature required for food storage, which is beneficial for food storage. In addition, the air duct 120 can direct cold air to the part of the refrigeration chamber 22 that is away from the cold air passage 220, so that cold air can also be blown to the part near the door 24, thereby ensuring the required storage temperature for the food placed in the bottle frame 26 of the door 24.

[0043] Combination Figure 1 , Figure 8 and Figure 9 As shown, the gas distribution device 10 can be inserted into the refrigeration chamber 22, such as the refrigerator compartment 22a. It can be understood that the gas distribution device 10 is generally perpendicular to the height direction of the refrigeration chamber 22. It should be noted that the thickness direction of the gas distribution body 12 is consistent with the height direction of the refrigeration chamber 22, the width direction of the gas distribution body 12 is consistent with the width direction of the refrigeration chamber 22, and the length direction of the gas distribution body 12 is consistent with the depth direction of the refrigeration chamber 22. Figure 8 As shown in the diagram, the width of the cooling chamber 22 is the distance in the left-right direction, and the depth of the cooling chamber 22 is the distance in the front-back direction.

[0044] like Figure 11As shown, to facilitate the assembly of the gas distribution device 10, a guide groove 222 for sliding of the gas distribution device 10 can be provided on the side wall of the refrigeration chamber 22. Thus, when the gas distribution device 10 is inserted into the refrigeration chamber 22, the side of the gas distribution device 10 can slide along the guide groove 222. Therefore, the guide groove 222 not only allows the gas distribution device 10 to slide stably, but also supports the gas distribution device 10, ensuring its stable assembly within the refrigeration chamber 22. The guide groove 222 can be provided on the side wall of the refrigeration chamber 22 and can extend along the depth direction of the refrigeration chamber 22.

[0045] Combination Figure 12 and Figure 13 As shown, a slot 162 can be provided on the wall of the refrigeration chamber 22. Correspondingly, a claw 160 capable of engaging the slot 162 can be provided on the circumferential wall of the clamping box 14. Specifically, the slot 162 can be provided on the rear wall of the refrigeration chamber 22, that is, the wall of the refrigeration chamber 22 facing the door 24. Thus, the claw 160 can be provided on the wall of the clamping box 14 opposite to the rear wall of the refrigeration chamber 22. Specifically, the slot 162 can be provided on the rear wall of the refrigeration chamber 22, that is, the wall of the refrigeration chamber 22 facing the door.

[0046] Combination Figure 7 and Figure 10 As shown, a support boss 28 can be provided on the wall of the refrigeration chamber 22, located below the gas distribution device 10 and protruding into the refrigeration chamber 22. The support boss 28 can be provided on the side wall of the refrigeration chamber 22, and a gap 184 can be provided on the support boss 28, which can make the support boss 28 intermittent. The gas distribution device 10 for the refrigeration equipment may include an elastic arm 180 provided on the bottom wall of the bottom shell 140 and an engaging boss 182 provided on the elastic arm 180 and capable of engaging with the gap 184. The elastic arm 180 can be configured to elastically move the engaging boss 182 in the height direction of the clamping box 14 to avoid the supporting boss 28. When the gas distribution device 10 is inserted, the elastic arm 180, under the pressure applied by the supporting boss 28, can move the engaging boss 182 away from the supporting boss 28 to avoid it. After the engaging boss 182 engages into the gap 184, the elastic arm 180 can move the engaging boss 182 toward the supporting boss 28 to reset it. It should be noted that the supporting boss 28 can be located below the guide groove 222.

[0047] Furthermore, it is clear that when the gas distribution device 10 needs to be disassembled, it can be pulled out. Since the gas distribution device 10 is detachably installed in the refrigeration chamber 22, it is easy to install and maintain. It is not only highly operable, but also allows the gas distribution device 10 to be standardized for widespread application in various types of refrigerators.

[0048] Combination Figure 3 and Figure 6 As shown, the air duct 120 may include a first air duct 120a extending in a direction perpendicular to the height of the cooling chamber 22 and a second air duct 120b communicating with the first air duct 120a, from... Figure 3 As shown in the diagram, the first air duct 120a can extend horizontally, and the second air duct 120b extends from inside the gas distribution body 12 to the bottom wall of the gas distribution body 12. In this way, after the cold air is horizontally sent out in the first air duct 120a, it can be discharged downwards along the second air duct 120b. This not only facilitates the circulation of cold air, but also makes it easier for the cold air to reach the bottle frame 26 of the door 24.

[0049] like Figure 6 As shown, the second air duct 120b can be inclinedly arranged above the first air duct 120a along the height direction of the refrigeration chamber 22. The second air duct 120b can be connected to the first air duct 120a through a connecting channel 120c. The included angle β formed between the second air duct 120b and the first air duct 120a can be 30°C-35°C. By setting the included angle β within the above range, it is possible to further facilitate the circulation of cold air and make it easier for the cold air to reach the bottle frame 26 of the door 24. It can be understood that the included angle between the second air duct 120b and the horizontal direction can also be 30°C-35°C.

[0050] To further ensure the cooling temperature within the cooling chamber 22, multiple air ducts 120 can be provided within the gas distribution body 12. These air ducts 120 can be distributed along the width direction of the gas distribution body 12; that is, the multiple air ducts 120 can be spaced apart along the width direction of the cooling chamber 22. It should be noted that the cooling chamber 22 has a height direction, a depth direction, and a width direction perpendicular to both the height and depth directions.

[0051] Additionally, a main air duct 124 can be installed within the gas distribution body 12. The two ends of the main air duct 124 can respectively form a main inlet connected to the cold air channel 220 and a main outlet connected to multiple air duct outlets. In this way, the cold air in the cold air channel 220 (e.g., the refrigerated air duct 220a) first enters the main air duct 124 through the main inlet, and then is distributed to each air duct 120 through the main outlet of the main air duct 124. By installing a main air duct 124 connected to multiple air ducts 120, stable flow of cold air within the air ducts can be ensured, thereby further guaranteeing the temperature uniformity and stability within the refrigeration chamber 22 (e.g., the refrigerated chamber 22a).

[0052] like Figure 3As shown, the gas distribution body 12 may include a first elastic body 12a and a second elastic body 12b covering the first elastic body 12a and capable of adhering to it. The first elastic body 12a is provided with a recess to form a corresponding air duct 120 after the first elastic body 12a and the second elastic body 12b are adhered to each other. It can be understood that by providing a corresponding recess on the first elastic body 12a, a corresponding air duct 120 or a corresponding main air duct 124 can be formed after the first elastic body 12a and the second elastic body 12b are adhered to each other. The location and shape of the recess can be set according to the location and shape of the corresponding air duct 120 or the main air duct 124. By incorporating the first elastic body 12a and the second elastic body 12b, the fabrication of the gas distribution body 12 is facilitated, as is the arrangement of the air duct 120 or main air duct 124 within the gas distribution body 12. Furthermore, since the first elastic body 12a and the second elastic body 12b can fit together, the airtightness of the air duct 120 is ensured. Both the first elastic body 12a and the second elastic body 12b can be made of foam.

[0053] In order to effectively protect the gas distribution body 12, combined with Figure 2 , Figure 4 and Figure 5 As shown, a clamping box 14 can be provided to clamp the gas distribution body 12. The clamping box 14 may include a bottom shell 140 and a cover 142 covering the bottom shell 140. It can be understood that the gas distribution body 12 can be clamped in the clamping box 14, and the clamping box 14 can limit the gas distribution body 12, thereby making the structure of the gas distribution body 12 more stable. The clamping box 14 may be provided with a cold air inlet 146 for cold air to enter. That is to say, the cold air inlet 146 can connect with the cold air channel 220. For example, if the refrigerated air duct 220a is connected, specifically, the cold air inlet 146 can be set on the circumferential wall of the clamping box 14. After the gas distribution device 10 is assembled in the refrigeration chamber 22, the cold air inlet 146 can be connected to the air outlet 220c of the cold air duct 220 to allow cold air to enter the air duct 120. The bottom wall of the bottom shell 140 can be provided with a cold air outlet 144 that is connected to the second air duct 120b for cold air discharge. In this way, cold air can be discharged downwards at an angle from the second air duct 120b. It should be noted that the cover 142 can be in the shape of a dome. The cover 142 can be placed on the bottom shell 140. A notch can be provided on the wall of the cover 142 so that after the cover 142 is placed on the bottom shell 140, it can be joined with the bottom shell 140 to form the cold air inlet 146.

[0054] like Figure 7 As shown, multiple cold air outlets 144 can be provided on the bottom wall of the bottom shell 140. The multiple cold air outlets 144 are distributed along the width direction of the refrigeration chamber 22, and the multiple cold air outlets 144 are respectively connected to the corresponding second air duct 120b.

[0055] Combination Figure 4 and Figure 5 As shown, a latching mechanism can be provided between the bottom shell 140 and the cover 142. The latching mechanism may include a latching arm 166 with a latching slot and a latch 164 capable of engaging with the latching slot. The latching arm 166 may be located on the bottom shell 140, and the latch 164 may be located on the cover 142; alternatively, the latching arm 166 may be located on the cover 142, and the latch 164 may be located on the bottom shell 140. By providing a latching mechanism, assembly between the bottom shell 140 and the cover 142 can be facilitated.

[0056] In addition, a sealing ring 19 can be set around the cold air inlet 146. The sealing ring 19 can fit tightly against the wall of the cooling chamber 22. Specifically, the sealing ring 19 can fit tightly against the wall of the cooling chamber 22 facing the door 24. In this way, cold air is less likely to leak at the cold air inlet 146, ensuring the amount of cold air in the cooling chamber 22 and allowing the cooling chamber 22 to cool down quickly.

[0057] The present invention also provides a refrigeration device. The refrigeration device 20 has been described in detail above and will not be repeated here. It is understood that the refrigeration device 20 may be configured with a refrigeration chamber 22, which has a cold air duct 220 for cold air passage. The refrigeration device 20 also includes a gas distribution device 10 installed within the refrigeration chamber 22. The gas distribution device 10 is the gas distribution device 10 for refrigeration devices provided by the present invention, wherein the air duct 120 is connected to the cold air duct 220. By installing this gas distribution device 10 in the refrigeration chamber 22 of the refrigeration device 20, such as a refrigerator compartment 22a, the refrigeration device 20 can provide a suitable temperature for the stored food, improving the food preservation effect.

[0058] A gas distribution device 10 is inserted into a cooling chamber 22. The wall of the cooling chamber 22 is provided with a guide groove 222 for the gas distribution device 10 to slide. Thus, when the gas distribution device 10 is inserted into the cooling chamber 22, the side of the gas distribution device 10 can slide along the guide groove 222. This not only stably guides the gas distribution device 10 but also effectively supports it, defining the gas distribution device 10 in the height direction of the cooling chamber 22. The guide groove 222 has been described above and will not be repeated here.

[0059] Refrigeration equipment 20 may include a door 24 for closing the refrigeration chamber 22 and a bottle frame 26 disposed on the door 24 and located inside the refrigeration chamber 22, to facilitate the circulation of cold air within the refrigeration chamber 22, such as Figure 14As shown, a passage 260 for cold air to pass through can be opened on the bottom wall of the bottle frame 26. The passage 260 can be elongated and can extend along the length of the bottle frame 26. It should be noted that the length of the bottle frame 26 can be consistent with the width of the refrigeration chamber 22.

[0060] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the inventive concept, various simple modifications can be made to the technical solutions of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
