Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, specifically providing an air duct assembly, a housing, and refrigeration equipment. Background Technology

[0002] Existing refrigeration equipment on the market, taking refrigerated cabinets as an example, basically uses rear-exhaust cooling. The air outlet is located on the rear panel and blows air forward. The air travels a long distance, so the drinks at the back get cold first, and by the time the air reaches the front, the temperature has already risen. This results in uneven beverage temperatures and a large temperature difference between the front and back of the drinks. Summary of the Invention

[0003] This application aims to solve the aforementioned technical problem, namely, to solve the problem that the air outlet of the existing refrigerator can only blow air forward, resulting in a large temperature difference between the front and back of the refrigerator.

[0004] This application provides an air duct assembly disposed within a refrigeration device. The air duct assembly includes: a mounting plate with an air outlet for supplying air into the refrigeration chamber of the refrigeration device; and an air guide section comprising a first air guide section and a second air guide section, the first air guide section and the second air guide section being disposed side by side at the air outlet, the first air guide section and the second air guide section having different orientations to supply air in different directions.

[0005] In the optional technical solutions of the above-mentioned air duct assembly, the first air guide is not perpendicular to the plane where the mounting plate is located, so that the first air guide tilts and directs the air from the air outlet.

[0006] In the optional technical solutions of the above-mentioned air duct assembly, the second air guide is not perpendicular to the plane where the mounting plate is located, and the inclination direction of the first air guide is opposite to that of the second air guide.

[0007] In the above-mentioned optional technical solutions for the air duct assembly, along the length direction of the air outlet, the proportion of the first air guide portion on the air outlet is greater than the proportion of the second air guide portion on the air outlet.

[0008] In the optional technical solutions of the above-mentioned air duct assembly, the acute angle formed between the first air guide and the mounting plate is smaller than the acute angle formed between the second air guide and the mounting plate.

[0009] In the optional technical solutions of the above-mentioned air duct assembly, an air duct side plate is also included. The air duct side plate is provided with a ventilation opening. The mounting plate is detachably disposed on the air duct side plate, and the air outlet corresponds to the ventilation opening. Multiple ventilation openings are provided, and the multiple ventilation openings are arranged along the height direction of the air duct side plate.

[0010] In the optional technical solutions of the above-mentioned air duct assembly, multiple mounting plates are provided, and the first air guide portion of the mounting plate located at the bottom is also inclined in a direction away from the mounting plate above.

[0011] This application also provides a housing, including: a cooling chamber; and an air duct assembly as described in any of the above technical solutions, disposed on the inner side wall of the cooling chamber, with the first air guide portion facing the opening end of the cooling chamber and the second air guide portion facing the inner rear wall of the cooling chamber.

[0012] In the above-mentioned optional technical solutions for the housing, the air duct assembly is provided in two sets, and the two sets of air duct assemblies are symmetrically arranged on the two inner side walls of the refrigeration chamber.

[0013] This application also provides a refrigeration device, which includes the air duct assembly described in any of the above technical solutions, or includes the housing described in the above technical solutions.

[0014] When the above technical solution is adopted, the air duct assembly is set on the inner wall of the refrigeration chamber. Since the air guiding directions of the first air guide and the second air guide are different, the air duct assembly can guide air in at least two directions, thereby avoiding the problem of uneven temperature in the refrigeration chamber caused by the air duct assembly only being able to blow air in a fixed direction.

[0027] like Figure 1 As shown, this application provides a refrigeration device 1. Figure 1The door of the refrigeration equipment 1 is not shown. The refrigeration equipment 1 includes a housing 10, and a refrigeration chamber 11 is provided inside the housing 10. An air duct assembly 12 is provided on the inner side wall 111 of the refrigeration chamber 11. The air duct assembly 12 can blow air to the opening end 113 of the refrigeration chamber 11 and the inner rear wall 112 of the refrigeration chamber 11, thereby improving the temperature uniformity inside the refrigeration equipment 1.

[0028] It should be noted that refrigeration equipment 1 can be a refrigerator, freezer, freezer, or other equipment that requires refrigeration.

[0029] Continue to refer to Figure 1 This application also provides a housing 10, as described above, in which a refrigeration chamber 11 is provided, and an air duct assembly 12 is provided on the inner sidewall 111 of the refrigeration chamber 11. In order to further improve the temperature uniformity in the refrigeration chamber 11, the air duct assembly 12 can be configured as two sets, and the two sets of air duct assemblies 12 are symmetrically arranged on the two inner sidewalls of the refrigeration chamber 11.

[0030] To further explain the working principle of the air duct assembly 12 in the cooling chamber 11, the air duct assembly 12 will be described in detail below.

[0031] Combination Figures 1 to 2 This application provides an air duct assembly 12, which includes a mounting plate 121 and an air guide section 122. The mounting plate 121 is provided with an air outlet 1211, which can deliver air into the cooling chamber 11 of the refrigeration equipment 1. The air guide section 122 includes a first air guide section 1221 and a second air guide section 1222, which are arranged side by side at the air outlet 1211. The first air guide section 1221 and the second air guide section 1222 face different directions so that the first air guide section 1221 and the second air guide section 1222 deliver air in different directions.

[0032] An air guide 122 is provided at the air outlet 1211, which can direct airflow to the part requiring cooling. For example... Figure 1 As shown, when the air duct assembly 12 is installed on the inner wall 111 of the cooling chamber 11, since the air guiding directions of the first air guide 1221 and the second air guide 1222 are different, the air duct assembly 12 can guide air in at least two directions, thereby avoiding the problem of uneven temperature in the cooling chamber 11 caused by the air duct assembly 12 only being able to blow air in a fixed direction.

[0033] In one embodiment, reference Figures 1 to 3The first air guide 1221 is not perpendicular to the plane of the mounting plate 121, so that the first air guide 1221 obliquely directs the air from the air outlet 1211. The opening end 113 of the refrigeration chamber 11 is provided with a door. Frequent opening of the door will cause the temperature at the opening end 113 of the refrigeration chamber 11 to rise, resulting in uneven temperature distribution in the front and back of the refrigeration chamber 11. Items near the opening end 113 of the refrigeration chamber 11 are more difficult to refrigerate, thus making the temperature of items near the opening end 113 of the refrigeration chamber 11 higher than the temperature of items near the inner rear wall 112 of the refrigeration chamber 11. When the air duct assembly 12 is installed inside the cooling chamber 11, the first air guide 1221 is tilted toward the opening end 113 of the cooling chamber 11. At this time, when the air in the air duct assembly 12 flows out from the air outlet 1211, the first air guide 1221 directs the air to the opening end 113 of the cooling chamber 11, thereby quickly cooling the opening end 113 of the cooling chamber 11. When a new item is placed near the opening end of the cooling chamber 11, it can also be quickly cooled, thus meeting the user's needs.

[0034] In one embodiment, reference continues... Figure 3 The second air guide 1222 is not perpendicular to the plane of the mounting plate 121, and the inclination directions of the first air guide 1221 and the second air guide 1222 are opposite. To avoid the air guides 122 all directing the air to the opening end 113 of the cooling chamber 11, thus causing uneven temperature distribution in the cooling chamber 11, a second air guide 1222 is also provided at the air outlet 1211. The inclination direction of the second air guide 1222 is opposite to that of the first air guide 1221. At this time, the first air guide 1221 discharges air towards the opening end 113 of the cooling chamber 11, and the second air guide 1222 discharges air towards the inner rear wall 112 of the cooling chamber 11, thereby ensuring a uniform temperature distribution in the cooling chamber 11 and ensuring that the items in front of and behind the cooling chamber 11 are at approximately the same temperature.

[0035] In one embodiment, reference continues... Figure 3Along the length of the air outlet 1211, the proportion of the first air guide 1221 on the air outlet 1211 is greater than that of the second air guide 1222 on the air outlet 1211. Since the opening end 113 near the refrigeration chamber 11 is more likely to come into contact with hot air when the door of the refrigeration chamber 11 is opened, resulting in a higher temperature at the opening end 113 than at the rear of the refrigeration chamber 11, this can be achieved by setting the airflow directed towards the opening end 113 of the refrigeration chamber 11 to be greater than the airflow directed towards the rear of the refrigeration chamber 11. Therefore, the area of ​​the air outlet 121 guided by the first air guide 1221 is set to be greater than the area of ​​the air outlet 1211 guided by the second air guide 1222 to achieve the above effect. Since the first air guide 1221 and the second air guide 1222 are arranged side by side at the air outlet 1211, it is only necessary to set the distribution length d1 of the first air guide 1221 along the air outlet 1211 to be greater than the distribution length d2 of the second air guide 1222 along the air outlet 1211. The length d of the air outlet 1211 is d = d1 + d2. At this time, the air volume guided by the first air guide 1221 to the opening end 113 of the cooling chamber 11 can be greater than the air volume guided by the second air guide 1222 to the rear side of the cooling chamber 11, thereby further improving the uniformity of the front and rear temperature distribution in the cooling chamber 11.

[0036] It should be noted that the ratio of the distribution length d1 of the first air guide 1221 along the air outlet 1211 to the distribution length d2 of the second air guide 1222 along the air outlet 1211 can be set to be no less than 6.5:3.5, thereby ensuring that there is enough air blowing towards the opening end 113 of the refrigeration chamber 11.

[0037] In one embodiment, reference continues... Figure 3The acute angle α1 formed between the first air guide 1221 and the mounting plate 121 is smaller than the acute angle α2 formed between the second air guide 1222 and the mounting plate 121. At this time, compared to vertically positioning the air guide 122 at the air outlet 1211, the angle at which the first air guide 1221 is inclined towards the opening end 113 of the cooling chamber 11 is greater than the angle at which the second air guide 1222 is inclined towards the inner rear wall 112 of the cooling chamber 11. This results in the acute angle α1 formed between the first air guide 1221 and the mounting plate 121 being smaller than the acute angle α2 formed between the second air guide 1222 and the mounting plate 121. Since the opening end 113 of the cooling chamber 11 is easily affected by external temperature when the door is opened, most of the air in the first air guide 1221 can be directly guided towards the opening end 113 of the cooling chamber 11. Since the temperature at the rear of the cooling chamber 11 is less affected by the external temperature, the tilt angle of the second air guide 1222 can be set to be less than the tilt angle of the first air guide 1221. Therefore, the air from the second air guide 1222 can be directed to the rear of the cooling chamber 11 and to the side perpendicular to the air outlet 1211. This can further improve the uniformity of the temperature distribution in the cooling chamber 11.

[0038] In one embodiment, reference Figure 4 and Figure 5 The air duct assembly 12 also includes an air duct side plate 123, which is provided with ventilation openings 1231. A mounting plate 121 is detachably mounted on the air duct side plate 123, and an air outlet 1211 corresponds to the ventilation openings 1231. Multiple ventilation openings 1231 are provided, arranged along the height direction of the air duct side plate 123. Airflow within the cooling chamber 11 exits through the ventilation openings 1231 of the air duct side plate 123, which correspond to the air outlets 1211, thereby guiding airflow through the air guide section 122 at the air outlet 1211. Multiple vents 1231 are arranged along the height direction of the duct side plate 123. Multiple mounting plates 121 can also be arranged and correspondingly positioned at the vents 1231, so that the vents 1231 correspond to the air outlets 1211. In this arrangement, the multiple mounting plates 121 along the height direction of the duct side plate 123 guide the airflow, ensuring uniform temperature distribution in the cooling chamber 11 along the height direction. The mounting plates 121 are detachably mounted on the duct side plate 123, allowing adjustment of the number of mounting plates 121 according to the airflow requirements in the direction of the opening end 113 of the cooling chamber 11, thus enabling more flexible temperature control of the cooling chamber 11. Furthermore, when the mounting plates 121 or the duct side plate 123 are damaged, only the damaged components need to be replaced, thus saving maintenance costs.

[0039] It should be noted that this application uses the example of two ventilation openings 1231 on the duct side panel 123 corresponding to one mounting plate 121 for illustration (e.g., Figure 5 As shown in the figure, of course, the above is not limiting. It can also be set that one vent 1231 corresponds to one mounting plate 121, or multiple vents 1231 correspond to one mounting plate 121. The above can be set according to the needs of those skilled in the art, and all of the above are within the protection scope of this application.

[0040] In one embodiment, combined with Figure 1 , Figure 4 and Figure 5 Multiple mounting plates 121 are provided, and the first air guide section 1221 of the lowest mounting plate 121 is inclined away from the upper mounting plate 121. Combined with Figure 1 and Figure 4 There are two types of first air guides 1221, including a first type of first air guide 1221a and a second type of first air guide 1221b. The first type of first air guide 1221a is located on the upper mounting plate 121 of the air duct side plate 123 and can discharge air towards the opening end 113 of the cooling chamber 11. The second type of first air guide 1221b is located on the lowermost mounting plate 121 and can discharge air towards the opening end 113 of the cooling chamber 11 and the lower side of the cooling chamber 11, that is, towards the lower front side 114 of the cooling chamber 11, thereby ensuring that the items located on the lower front side 114 of the cooling chamber 11 can be effectively cooled.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
