Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to an air conditioner cabinet and an air conditioner. Background Art

[0002] Cabinet air conditioners equipped with axial flow fans differ from those equipped with cross-flow fans. In cabinet air conditioners, the indoor heat exchanger is typically located behind the air inlet, rather than surrounding the impeller of the cross-flow fan as in cross-flow cabinet air conditioners. Therefore, when the cabinet air conditioner is in cooling mode, the lower-temperature air, which has undergone heat exchange with the indoor heat exchanger, passes through the roughly cylindrical duct where the axial flow fan is located. Because this air is cooler, the continued flow of cooler air will also cause the temperature of the duct walls to drop. The air outside the duct is hotter, and if the humidity is high, condensation is more likely to form when it encounters the cooler duct walls. Furthermore, the axial flow fan drives the air to flow from back to front, which also causes the space outside the duct to be continuously replenished with new air. The water vapor in the new air will also continuously condense on the outer walls of the duct. Utility Model Content

[0003] The first aspect of the present invention aims to provide an air-conditioning cabinet to solve the technical problem that condensation is easily generated inside the existing air-conditioning cabinet.

[0004] The air-conditioning cabinet provided in the first aspect of the present invention includes an air duct assembly, the air duct assembly has an air duct wall, an axial flow fan is provided in the air duct wall, and an anti-condensation structure is provided on the outer wall of the air duct wall; the anti-condensation structure includes an anti-condensation body, the anti-condensation body protrudes from the outer wall of the air duct wall and has a first cavity.

[0005] The beneficial effects brought by the utility model axial flow air conditioner cabinet are:

[0006] By providing a sealed first cavity around the periphery of the duct wall of the duct assembly, when the air conditioner cabinet is in operation, the gas flow generated by the rotation of the axial flow fan in the duct wall will not drive the flow of air in the first cavity. When cooler gas circulates inside the duct wall, the temperature of the duct wall decreases. When the air in the first cavity transfers heat to the duct wall, the air in the first cavity will not flow directly with the airflow behind the first cavity. The front space and front surface of the first cavity are relatively high, and it is not easy for air to form condensation on these surfaces. Moreover, the rotation of the axial flow fan will not replenish new air into the first cavity, and the air in the first cavity is relatively still and presents a gradient of gradually increasing temperature. The air that may produce condensation is not all the air in the first cavity, so the total amount of air available for producing condensation is small, which helps to slow down or even eliminate the generation of condensation. In an optional technical solution, the first cavity includes an annular cavity surrounded by the outer peripheral wall of the duct wall.

[0007] In an optional technical solution, the first cavity includes a cavity rear wall plate, which is connected to the rear end of the air duct wall; the air-conditioning cabinet has an air inlet cavity, which is located between the cavity rear wall plate and the rear panel of the air-conditioning cabinet, and the cavity rear wall plate separates the air inlet cavity and the first cavity.

[0008] A separate cavity rear wall plate is provided to form the rear side wall, so that the rear side wall and the air duct wall can be separately processed and formed and then assembled together, thereby reducing the height of the parts forming the rear side wall, and making the cavity rear wall plate flatter, reducing manufacturing difficulty and improving processing efficiency.

[0009] In an optional technical solution, the cavity rear wall plate is connected to the rear end of the air duct wall through a chamfered portion.

[0010] By setting a chamfered portion to connect the air duct wall and the cavity rear wall plate, the airflow direction changes gently in the process of entering the air duct wall from the rear surface of the cavity rear wall plate, thereby reducing wind resistance and improving operating efficiency.

[0011] In an optional technical solution, the upper edge, lower edge, left edge and right edge of the cavity rear wall plate are all provided with flange portions, the flange portion of the upper edge is bent forward and abuts the lower surface of the cavity top wall of the first cavity, the flange portion of the lower edge is bent forward and abuts the upper surface of the cavity bottom wall of the first cavity, the flange portion of the left edge is bent forward and abuts the right surface of the cavity left wall of the first cavity, and the flange portion of the right edge is bent forward and abuts the left surface of the cavity right wall of the first cavity.

[0012] By arranging a flange portion on the edge of the cavity rear wall plate, the folded portion can be used to fit with the inner surfaces of the cavity top wall, cavity bottom wall, cavity left wall and cavity right wall of the first cavity, which not only increases the fitting area and improves the sealing of the first cavity, but also the flange portion can be used to be parallel to the top wall, bottom wall and left and right side walls of the first cavity to fix the cavity rear wall plate to the first cavity, thereby improving the stability of the cavity rear wall plate.

[0013] In an optional technical solution, the cavity rear wall plate is connected to the rear end of the air duct wall through a sub-port structure.

[0014] By setting a sub-port to connect the cavity rear wall plate and the rear end of the air duct wall, a lap structure can be formed, and a labyrinth seal is formed at the connection part between the cavity rear wall plate and the air duct wall to prevent air leakage from the rear end of the air duct wall.

[0015] In an optional technical solution, the air-conditioning cabinet includes a plurality of air duct components, and the cavity rear wall plate has a central recessed portion, and the central recessed portion is located between adjacent air duct components.

[0016] By setting a central recessed portion in the area between adjacent duct components, the cavity rear wall panel can be set to a structure with a concave and convex shape, thereby strengthening the overall structure of the cavity rear wall panel. In this way, when the distance between the duct components increases, the overall stiffness of the cavity rear wall panel in the area between the duct components can still be guaranteed, thereby reducing the noise during the operation of the air-conditioning cabinet.

[0017] In an optional technical solution, the cavity rear wall plate also includes an annular circumferential wall portion and an annular rear wall portion, the annular circumferential wall portion surrounds the outer side of the air duct wall, and the annular rear wall portion connects the rear end of the annular circumferential wall portion and the rear end of the air duct wall.

[0018] By arranging the annular peripheral wall portion and the annular rear wall portion around the air duct wall, the rigidity of the cavity rear wall plate around the air inlet of the air duct assembly can be increased to ensure that it can fit tightly with the rear end of the air duct wall.

[0019] In an optional technical solution, the first cavity is an annular cavity surrounded by the outer peripheral wall of the air duct wall.

[0020] By setting the first cavity to include an annular cavity surrounding the outer wall of the air duct wall, the outer wall of the air duct wall can be separated from the hotter air outside by the first cavity in all 360° directions, so that condensation will not be formed directly on the outer wall of the air duct wall due to the temperature difference between the inside and outside of the air duct wall.

[0021] In an optional technical solution, the first cavity is an arc-shaped cavity surrounded by the outer peripheral wall of the air duct wall.

[0022] The first cavity is set as an arc-shaped cavity surrounded by the outer peripheral wall of the air duct wall. The first cavity of the arc-shaped cavity can be used to achieve separation within at least a partial circumferential angle range of the outer peripheral wall of the air duct wall, thereby preventing condensation on the front side wall of the first cavity.

[0023] The second aspect of the present invention aims to provide an air conditioner to solve the technical problem that condensation is easily generated inside the air conditioner cabinet.

[0024] The air conditioner provided in the second aspect of the present invention comprises an air conditioner outdoor unit and any one of the above-mentioned air conditioner cabinet units, wherein the air conditioner outdoor unit is connected to the air conditioner via a refrigerant connecting pipe.

[0025] By arranging the above-mentioned air-conditioning cabinet in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned air-conditioning cabinet, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] Unless otherwise specified, the definitions of directions in this application are as follows: the front refers to the side of the air-conditioning cabinet facing the main indoor space, and the back refers to the side of the air-conditioning cabinet facing the wall it is close to. The bottom refers to the side of the air-conditioning cabinet facing the ground. The top refers to the side of the air-conditioning cabinet facing the roof. The left and right can be defined based on the above-mentioned front, back and bottom, that is, when the observer faces the wall to which the air-conditioning cabinet is installed, the observer's left hand direction is the left side, and the observer's right hand direction is the right side. In addition, the inside and the outside are defined based on the components in the shape of a cavity, box or cylinder. The side of the cavity, box or cylinder facing its internal space is the inside, and the outside is the side of the cavity, box or cylinder facing its external space.

[0039] Example 1:

[0040] Figure 1 This is a schematic cross-sectional view of the air conditioning cabinet provided in Example 1 of the present utility model; Figure 2 This is a schematic cross-sectional view of the air conditioning cabinet provided in the first embodiment of the present invention as viewed from another direction; Figure 1-Figure 2 As shown, the air-conditioning cabinet provided in the first embodiment of the present invention includes an air duct assembly 100, the air duct assembly 100 has an air duct wall 110, an axial flow fan 120 is provided in the air duct wall 110, and an anti-condensation structure is provided on the outer wall of the air duct wall 110; the anti-condensation structure includes an anti-condensation body, the anti-condensation body protrudes from the outer wall of the air duct wall 110, and has a first cavity 400.

[0041] By providing a sealed first cavity 400 around the outer periphery of the duct wall 110 of the air duct assembly 100, when the air conditioner cabinet is in operation, the air flow generated by the rotation of the axial flow fan 120 within the duct wall 110 does not drive the air flow within the first cavity 400. When cooler air circulates within the duct wall 110, the temperature of the duct wall 110 decreases. When the air within the first cavity 400 transfers heat to the duct wall 110, the air within the first cavity 400 does not flow directly with the airflow behind the first cavity 400. The front space and front surface of the first cavity 400 are relatively high, making it less likely for air to form condensation on these surfaces. Furthermore, the rotation of the axial flow fan 120 does not replenish new air into the first cavity 400. The air within the first cavity 400 is relatively static and exhibits a gradually increasing temperature gradient. Therefore, the air that may condense is not all of the air within the first cavity 400. Therefore, the total amount of air available for condensation is relatively small, helping to slow down or even eliminate the formation of condensation.

[0042] In this embodiment, the axial flow fan 120 includes a rotor motor and an axial flow fan fixedly connected to the power output end of the rotor motor, and the rotor motor and the axial flow fan are both in the air duct wall 110. Since the rotor motor and the axial flow fan are not the focus of the improvement of this application, they are not described here.

[0043] like Figure 1-Figure 2 As shown, optionally, the first cavity 400 includes an annular cavity surrounded by the outer peripheral wall of the air duct wall 110 .

[0044] By setting the first cavity 400 to include an annular cavity surrounding the outer wall of the air duct wall 110, the outer wall of the air duct wall 110 can be separated from the hotter air outside through the first cavity 400 in all 360° directions, so that condensation will not be directly formed on the outer wall of the air duct wall 110 due to the temperature difference between the inside and outside of the air duct wall 110.

[0045] The annular cavity in this embodiment is not limited to a circular cavity. In this embodiment, as long as the cavity can surround the circumference of the air duct wall 110, it can be an annular cavity. Specifically, the inner sidewall of the annular cavity in this embodiment can be cylindrical, like the air duct wall 110, while the outer sidewall of the annular cavity can be rectangular.

[0046] In this embodiment, two air duct assemblies 100 are arranged vertically in one air conditioning cabinet. Naturally, two air inlets are provided on the cavity rear wall plate 200 corresponding to the rear ends of the two air duct walls 110. The annular cavities surrounded by the outer sides of the two air duct walls 110 can be connected.

[0047] like Figure 1-Figure 2 As shown, optionally, the first cavity 400 includes a cavity rear wall panel 200, which is connected to the rear end of the air duct wall 110; the air-conditioning cabinet has an air inlet cavity 500, which is located between the cavity rear wall panel 200 and the rear panel 300 of the air-conditioning cabinet, and the cavity rear wall panel 200 separates the air inlet cavity 500 and the first cavity 400.

[0048] Setting the cavity rear wall panel 200 to be connected to the rear end of the air duct wall 110 allows the cavity rear wall panel 200 and the air duct wall 110 to be separately processed and formed and then assembled together, thereby reducing the height of the parts forming the cavity rear wall panel 200, and making the cavity rear wall panel 200 flatter, reducing the manufacturing difficulty.

[0049] In this embodiment, after the air enters the air intake cavity 500 from the air intake port 310 of the rear panel 300, it undergoes heat exchange with the indoor heat exchanger to form cold air or hot air, and is driven by the axial flow fan 120 of the air duct assembly 100 and blown out of the air outlet through the air duct assembly 100 to cool or heat the indoor space.

[0050] like Figure 1-Figure 2 As shown, optionally, the cavity rear wall plate 200 is connected to the rear end of the air duct wall 110 through a chamfered portion 210 .

[0051] By setting a chamfered portion 210 to connect the air duct wall 110 and the cavity rear wall plate 200, the airflow direction can change gently in the process of entering the air duct wall 110 from the rear surface of the cavity rear wall plate 200, thereby reducing wind resistance and improving operating efficiency.

[0052] Specifically, in this embodiment, the chamfered portion 210 can be a circular arc or elliptical arc with a central angle of 90° or a circular arc or elliptical arc with a central angle of more than 70°, and the chamfered portion 210 is provided at each circumferential position at the rear end of the air duct wall 110.

[0053] like Figure 1-Figure 2 As shown, optionally, the upper edge, lower edge, left edge and right edge of the cavity rear wall plate 200 are provided with a flange portion 220, the flange portion 220 of the upper edge is bent forward and abuts the lower surface of the cavity top wall 401 of the first cavity 400, the flange portion 220 of the lower edge is bent forward and abuts the upper surface of the cavity bottom wall 402 of the first cavity 400, the flange portion 220 of the left edge is bent forward and abuts the right surface of the cavity left wall 403 of the first cavity 400, and the flange portion 220 of the right edge is bent forward and abuts the left surface of the cavity right wall of the first cavity 400.

[0054] By providing a flange portion 220 on the edge of the cavity rear wall plate 200, the folded portion can be used to fit with the inner surfaces of the cavity top wall 401, the cavity bottom wall 402, the cavity left wall 403, and the cavity right wall (not shown in the figure) of the first cavity 400. This not only increases the fitting area and improves the sealing of the first cavity 400, but also the flange portion 220 can be used to be parallel to the inner surfaces of the cavity top wall 401, the cavity bottom wall 402, the cavity left wall 403, and the cavity right wall of the first cavity 400 to fix the cavity rear wall plate 200 to the first cavity 400, thereby improving the stability of the cavity rear wall plate 200.

[0055] Specifically, in this embodiment, the circumferential sidewalls of the first cavity 400 include the inner surfaces of the cavity top wall 401, cavity bottom wall 402, cavity left wall 403, and cavity right wall (not shown) of the first cavity 400. The upper edge, lower edge, and left and right edges of the cavity rear wall plate 200 are all provided with forward-bent flange portions 220, which respectively mate with the lower surface of the cavity top wall 401, the upper surface of the cavity bottom wall 402, and the inner surfaces of the cavity left wall 403 and cavity right wall. Through holes can be provided in these sidewalls to securely install the cavity rear wall plate 200 using male threaded connectors such as screws or bolts.

[0056] Figure 3 A schematic cross-sectional view of an air conditioning cabinet provided in another implementation of the first embodiment of the present utility model; Figure 4This is a schematic cross-sectional view of an air conditioning cabinet unit viewed from another direction, provided in another implementation of the first embodiment of the present utility model; Figure 3-Figure 4 As shown, optionally, the air conditioning cabinet includes a plurality of air duct assemblies 100 , and the cavity rear wall plate 200 has a central recessed portion 230 , and the central recessed portion 230 is located between adjacent air duct assemblies 100 .

[0057] By setting a central recessed portion 230 in the area between adjacent duct assemblies 100, the cavity rear wall plate 200 can be set to a structure having a concave and convex shape, so that when the distance between the duct assemblies 100 increases, the overall stiffness of the cavity rear wall plate 200 in the area between the duct assemblies 100 can still be ensured, thereby reducing the noise during the operation of the air-conditioning cabinet.

[0058] Specifically, in this embodiment, the height of the middle recess 230 , that is, the size of the middle recess 230 in the up and down directions, gradually increases from the middle in the left and right directions to the left and right ends, so as to facilitate matching with the shape of the air duct wall 110 .

[0059] The sidewall of the middle recessed portion 230 of this embodiment may be recessed forward in a direction close to the horizontal direction, that is, the angle between its extension direction and the front-back direction may be the draft taper required for injection molding.

[0060] like Figure 3-Figure 4 As shown, optionally, the middle recessed portion 230 is provided with a first reinforcing rib 231 .

[0061] By providing the first reinforcing rib 231 in the central recessed portion 230 , the rigidity and strength of the front wall of the central recessed portion 230 can be increased, and the vibration of the front wall of the central recessed portion 230 can be reduced when the air conditioner cabinet is running, thereby reducing noise.

[0062] In this embodiment, the first reinforcing ribs 231 may be reinforcing ribs that cross each other horizontally and vertically and are disposed on the rear surface of the middle recessed portion 230 .

[0063] like Figure 3-Figure 4 As shown, optionally, the cavity rear wall plate 200 also includes an annular circumferential wall portion 241 and an annular rear wall portion 242, the annular circumferential wall portion 241 surrounds the outer side of the air duct wall 110, and the annular rear wall portion 242 connects the rear end of the annular circumferential wall portion 241 and the rear end of the air duct wall 110.

[0064] By surrounding the annular peripheral wall portion 241 and the annular rear wall portion 242 on the air duct wall 110 , the rigidity of the cavity rear wall plate 200 around the air inlet of the air duct assembly 100 can be increased to ensure that it can fit tightly with the rear end of the air duct wall 110 .

[0065] In this embodiment, the annular rear wall portion 242 connects the chamfered portion 210 and the rear end of the annular circumferential wall portion 241. The lower front end of the upper annular circumferential wall portion 241 is connected to the central recessed portion 230, while the upper front end of the lower annular circumferential wall portion 241 is connected to the central recessed portion 230. In this embodiment, the opposing areas of the two annular circumferential wall portions 241 surrounding the outer sides of the two air duct assemblies 100 are also connected to the first reinforcing rib 231.

[0066] like Figure 3-Figure 4 As shown, optionally, a second reinforcing rib 243 is provided on the front side of the annular rear wall portion 242 .

[0067] The provision of the second reinforcing ribs 243 increases the rigidity of the area where the annular rear wall portion 242 connects to the rear end of the duct wall 110, thereby preventing deformation at the location where the cavity rear wall plate 200 connects to the rear end of the duct wall 110 and preventing air leakage at the rear end of the duct wall 110. Furthermore, the second reinforcing ribs 243 are provided on the front side of the annular rear wall portion 242. Airflow entering the duct assembly 100 is blocked by the annular rear wall portion 242 and does not enter the space enclosed by the duct wall 110, the annular rear wall portion 242, and the annular peripheral wall portion 241, nor does it pass through the second reinforcing ribs 243, thereby reducing operating noise of the air conditioner cabinet.

[0068] The second reinforcing ribs 243 are perpendicular to the front surface of the annular rear wall portion 242 and can connect the front surface of the annular rear wall portion 242 and the outer peripheral surface of the chamfered portion 210. The second reinforcing ribs 243 are arranged along the radial direction of the air duct wall 110 and can be distributed along the circumference. Specifically, the second reinforcing ribs 243 can be crescent-shaped.

[0069] like Figure 3-Figure 4 As shown, optionally, the cavity rear wall plate 200 is connected to the rear end of the air duct wall 110 through a sub-port structure.

[0070] By setting a sub-opening to connect the cavity rear wall plate 200 and the rear end of the air duct wall 110, an overlapping structure can be formed, and a labyrinth seal is formed at the connection part between the cavity rear wall plate 200 and the air duct wall 110 to prevent air leakage at the rear end of the air duct wall 110.

[0071] Specifically, in this embodiment, in the sub-mouth structure, the first end face annular ridge 211 of the cavity rear wall plate 200 protrudes forward from the chamfered portion 210, and the first end face annular ridge 211 arranged on the cavity rear wall plate 200 is located radially inner than the second end face annular ridge 111 arranged on the rear end face of the air duct wall 110. Therefore, when the airflow flows along the chamfered portion 210 and turns, it can first pass through the inner circumferential surface of the first end face annular ridge 211, and then flow to the inner circumferential surface of the air duct wall 110, thereby preventing the airflow from leaking from between the first end face annular ridge 211 and the second end face annular ridge 111.

[0072] Furthermore, in this embodiment, a first guide portion 212 is provided on the front end surface of the first end surface annular ridge 211, and a second guide portion 112 is provided on the rear end surface of the second end surface annular ridge 111. The first guide portion 212 has an outer conical surface that is larger at the front and smaller at the rear, while the second guide portion 112 has an inner conical surface that is smaller at the front and larger at the rear. The two guide portions cooperate with each other to guide the assembly process of the cavity rear wall panel 200 and the air duct wall 110 when the relative positions of the two are not very precise, thereby improving installation efficiency.

[0073] In an implementation not shown in the figures, the first cavity 400 is an arc-shaped cavity surrounded by the outer peripheral wall of the air duct wall 110 .

[0074] The first cavity 400 is set as an arc-shaped cavity surrounded by the outer wall of the air duct wall 110. The first cavity 400 of the arc-shaped cavity can be used to achieve separation within at least a partial circumferential angle range of the outer wall 110 of the air duct wall, thereby preventing condensation from occurring on the front side wall of the first cavity 400.

[0075] Specifically, for each air duct wall 110, two first cavities 400 can be set, and the two first cavities 400 are respectively located above and below the air duct wall 110, so that each arc-shaped cavity can cover a circumferential angle of more than 170° of the air duct wall 110, and can basically meet the thermal insulation needs of the air duct wall 110.

[0077] The second embodiment further provides an air conditioner, comprising an air conditioner outdoor unit and any one of the above-mentioned air conditioner cabinet units, wherein the air conditioner outdoor unit is connected to the air conditioner via a refrigerant connecting pipe.

[0078] By arranging the above-mentioned air-conditioning cabinet in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned air-conditioning cabinet, which will not be described in detail here.
