Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0047] The present invention provides an air conditioning cabinet, which can solve the problem of poor comfort in the cooling mode of conventional air conditioning cabinets. Figures 1 to 18 In the embodiment, the solid arrow indicates a space, a slot or a hole; the dashed arrow indicates the airflow direction.

[0048] See also Figures 1 to 3 The air conditioning cabinet 100 of the present invention comprises a shell 10, a volute assembly and a first guide plate 40a; wherein the shell 10 is provided with a first air outlet 11 and a second air outlet 12, and the first air outlet 11 and the second air outlet 12 both extend in the up-down direction; the volute assembly is installed in the shell 10, and the volute assembly comprises a volute tongue 50 and a volute 60, and the volute 60 and the volute tongue 50 are enclosed to form an air outlet duct connected with the first air outlet 11; and the shell 10 is provided with a vent on the front side of the volute tongue 50, and the vent is connected with the air outlet duct and the second air outlet 12; the first guide plate 40a is movably connected with the front end of the volute tongue 50 to open or close the vent.

[0049] Specifically, the air-conditioning cabinet 100 is a circular cabinet, so the shell 10 of the air-conditioning cabinet 100 is arranged in a circular cylindrical shape. In other embodiments, the air-conditioning cabinet 100 is a square cabinet, and its shell 10 is arranged in a square cylindrical shape. In addition, the shell 10 can also be arranged in an elliptical cylindrical shape, and there is no specific limitation. It can be designed accordingly according to the actual installation position or the size of the occupied space. The shell 10 includes a back plate and a panel, wherein the back plate is provided with an air inlet; the panel is provided with a first air outlet 11 and a second air outlet 12, and the first air outlet 11, the second air outlet 12 and the third air outlet 13 all extend in the up and down direction.

[0050] The first air outlet 11 and the second air outlet 12 can be separated, or the first air outlet 11 and the second air outlet 12 can be connected and connected to form a complete air outlet. The vent can be opened at the front end of the volute tongue 50; or the front end of the volute tongue 50 is spaced from the panel of the housing 10 to separate the vent.

[0051] See also Figure 2 and Figure 3 The air conditioner cabinet 100 also includes a crossflow impeller 20 and a heat exchanger 30 installed in the housing 10. When the crossflow impeller 20 is working, the crossflow impeller 20 rotates to drive the airflow to enter the housing 10 from the air inlet. The airflow exchanges heat with the heat exchanger 30 to form an outlet airflow, which blows from the outlet duct to each outlet to achieve cooling or heating. Figure 2 If the user needs regular air outlet, the first air guide plate 40a can cover the vent, and the air flow is blown out from the first air outlet 11. Figure 3 If the user needs windless air outlet, the first guide plate 40a will open the vent, so that the air flow is blown out through the first air outlet 11 and the second air outlet 12. The air supply surface of the air-conditioning cabinet 100 is increased, the air supply range is wider, and the air outlet is effectively dispersed, so that the air speed is reduced and becomes softer, thereby achieving a windless effect and improving comfort.

[0052] The technical solution of the present invention is to provide a vent connecting the air outlet duct and the second air outlet 12 on the front side of the volute tongue 50, and movably connect the first guide plate 40a with the front end of the volute tongue 50, so that when the user needs windless air outlet, the first guide plate 40a opens the vent, so that the first air outlet 11 and the second air outlet 12 can divert the air, expand the air supply area, achieve a windless effect, and improve comfort; and when the first guide plate 40a closes the vent, conventional air outlet is achieved through the first air outlet 11.

[0053] See also Figure 2 and Figure 3As for the movable connection between the first guide plate 40a and the volute tongue 50, the first guide plate 40a can also be rotatably connected to the volute tongue 50, and the first guide plate 40a can rotate toward the air outlet duct to cover the wind-blocking state of the vent, and rotate in the opposite direction to open the vent. Expanded state.

[0054] Specifically, the first guide plate 40a is rotatably connected to the front end of the volute tongue 50. When the first guide plate 40a slides to the wind blocking state, the first guide plate 40a guides the outlet airflow to the first air outlet 11. When the first guide plate 40a rotates in the reverse direction to the unfolded state, the first guide plate 40a is located behind the second air outlet 12, and the first guide plate 40a guides part of the outlet airflow to the second air outlet 12.

[0055] See also Figure 4 and Figure 5 As for the rotation of the first air guide plate 40a, it can be rotated alone or in conjunction with other rotating structures inside the housing 10. In view of the fact that a plurality of air guide plates 30 are rotatably mounted at the first air outlet 11; in order to reduce the number of rotating structures and reduce the occupied space, and increase the cost, preferably, the first air guide plate 40a is connected to the air guide plate 30 through a first linkage structure, and the first linkage structure drives the air guide plate 30 to deflect toward the second air outlet 12 when the first air guide plate 40a is unfolded.

[0056] See also Figure 4 When the user needs to have windless air outlet, the first guide plate 40a can be rotated to the unfolded state, the vent is opened, and part of the airflow in the air outlet duct flows to the second air outlet 12; in this process, the first linkage structure drives the guide plate 30 to deflect toward the second air outlet 12, so that the guide plate 30 deflects the outlet airflow toward the second air outlet 12, thereby effectively diverting the airflow to the first air outlet 11 and the second air outlet 12.

[0057] See also Figure 5 When the user needs a conventional air outlet, the first guide plate 40a can be rotated to the wind-blocking state, and the vent is closed. During this process, the first linkage structure drives the guide plate 30 to deflect away from the second air outlet 12, so that the guide plate 30 deflects the outlet air flow toward the other side of the first air outlet 11, so that the current air flow is blown forward from the first air outlet 11.

[0058] See also Figures 6 to 8 As for the movable connection between the first guide plate 40a and the volute tongue 50, the first guide plate 40a and the volute tongue 50 can be slidably connected, and the first guide plate 40a has a wind-blocking state that slides to cover the vent, and a receiving state that slides to open the vent.

[0059] Specifically, the first guide plate 40a and the volute tongue 50 can cooperate with each other through the groove rail structure. When the first guide plate 40a slides to the wind blocking state, the first guide plate 40a guides the outlet airflow to the first air outlet 11. When the first guide plate 40a slides to the storage state, the vent is opened to connect the outlet air duct and the second air outlet 12, so that the outlet airflow in the outlet air duct can partially flow to the second air outlet 12 and be blown out from the second air outlet 12.

[0060] Here, in order to prevent the first guide plate 40a from interfering with the internal structure of the shell 10 when it is in the accommodated state, an accommodating cavity or an accommodating groove for accommodating the first guide plate 40a may be provided on or behind the volute tongue 50.

[0061] See also Figure 8 and Fig. 9 There is no specific limitation on the shape and structure of the first guide plate 40a. The first guide plate 40a can be arranged in a flat plate shape; or the first guide plate 40a can be arranged in an arc shape. In order to facilitate the first guide plate 40a to guide the wind, the latter design is preferably adopted. Fig. 9 For example, the first guide plate 40a may be concavely disposed facing away from the volute 60 and in a concave arc shape, so that the first guide plate 40a guides the airflow forward and reduces the noise generated by the airflow impacting the first guide plate 40a. For another example, the first guide plate 40a may be convexly disposed facing the volute 60 and in a convex arc shape, so that when the outlet airflow contacts the first guide plate 40a, it flows along the convex arc surface of the first guide plate 40a, and the first guide plate 40a guides the airflow toward the side, increasing the air supply angle, thereby obtaining a wider air supply range.

[0062] See also Fig. 9 In addition, since the volute 60 includes a shell section 61 located outside the air outlet, and the shell section 61 is located on one side of the first air outlet 11, the shell section 61 can be arranged in an arc shape to expand the air supply range of the first air outlet 11. For example, the shell section 61 can be arranged concavely with its back to the volute tongue 50, and in a concave arc shape, so that the first air outlet 11 can be expanded, the air supply range can be effectively increased, and the noise generated by the airflow impacting the shell section 61 can be reduced. For another example, the shell section 61 can also be arranged convexly facing the volute tongue 50, and in a convex arc shape, so that when the outlet airflow contacts the shell section 61, it flows along the convex arc surface of the shell section 61, and the shell section 61 guides the airflow toward the side, and the air supply angle is increased, thereby obtaining a wider air supply range.

[0063] See also Figures 10 to 12In the second embodiment of the present invention, on the basis of the above-mentioned first embodiment, the housing 10 is further provided with a third air outlet 13 extending in the up-down direction, and the third air outlet 13 is located on the side of the first air outlet 11 that is farther away from the second air outlet 12. When the user needs a large-scale air supply, the user can choose to open any two or three of the first air outlet 11, the second air outlet 12 and the third air outlet 13 to achieve multi-faceted air supply, with a more dispersed air volume and a lower wind speed, thereby achieving a large-scale windless air supply. When the user needs conventional air supply, the user can choose to open any one of the first air outlet 11, the second air outlet 12 and the third air outlet 13 to achieve conventional air supply.

[0064] See also Figures 10 to 12 Here, in order to facilitate the user to switch the air supply between the first air outlet 11, the second air outlet 12 and the third air outlet 13, in the present embodiment, the front end of the volute 60 is provided with an air outlet connecting the third air outlet 13 and the air outlet duct; and the air-conditioning cabinet 100 also includes a second guide plate 40b rotatably connected to the outer edge of the air outlet, and the second guide plate 40b has a first unfolded state in which the air outlet is opened by rotating toward the inner side of the air outlet duct, and a wind-blocking state in which the air outlet is covered by rotating in the opposite direction.

[0065] When the second guide plate 40b is in the wind-blocking state, the second guide plate 40b covers the air outlet, the second guide plate 40b is spliced ​​with the volute 60 as a whole, and the second guide plate 40b guides the outlet airflow in the outlet air duct to other outlets. When the second guide plate 40b is in the first unfolded state, the second guide plate 40b opens the air outlet, the second guide plate 40b is located in the outlet air duct, and the second guide plate 40b guides the outlet airflow in the outlet air duct to the air outlet, and blows it out through the third outlet 13.

[0066] See also Fig.12 Here, it is also considered that when the user switches between the conventional air outlet mode and the multi-faceted windless mode, the second guide plate 40b and the first guide plate 40a need to be controlled to rotate one by one. If a rotating structure is provided for each guide plate, it will inevitably take up a large space and increase the cost. Therefore, it is preferred that the second guide plate 40b is connected to the first guide plate 40a through a second linkage structure. When the first guide plate 40a opens the vent, the linkage structure drives the second guide plate 40b to open the vent. The linkage structure is relatively common in the current market and is not listed in detail here.

[0067] See also Fig.13In addition, since the third air outlet 13 is adjacent to the front end of the volute 60, and the front end of the volute 60 is near a low pressure area, and the outside of the housing 10 is a high pressure area, the third air outlet 13 can be switched to a return air outlet 14 by reasonably designing the rotation direction of the second air guide plate 40b, that is, the external air can enter the air outlet duct from the third air outlet 13. For example, based on the above embodiment, the second air guide plate 40b also has a second unfolded state in which the second air guide plate 40b rotates toward the third air outlet 13 to open the air outlet, and in the second unfolded state, the external air enters the air outlet duct from the third air outlet 13.

[0068] See also Fig.13 Obviously, when the second guide plate 40b is in the second expanded state, the second guide plate 40b opens the air outlet, and the second guide plate 40b is located in the air duct between the air outlet and the second air outlet 12; at this time, the air flow blown out from the air outlet duct has a faster wind speed, and is quickly blown out to the end of the air outlet duct under the action of inertia, thereby forming a low-pressure area at the front end of the volute 60, and the air outside the shell 10 enters the air outlet duct from the third air outlet 13. This part of air is mixed with the air flow in the air outlet duct, and the mixed air flow is blown out from other air outlets. On the one hand, the air outlet temperature is slightly increased, the wind speed is reduced, and the air outlet is softer and more comfortable, achieving a windless effect; on the other hand, the air outlet volume can be increased.

[0069] See also Fig.13 In this embodiment, in order to enhance the windless air outlet effect of the air conditioner cabinet 100, a first micro-perforated plate may be installed at the first air outlet 11; a second micro-perforated plate may be installed at the second air outlet 12; and a third micro-perforated plate may be installed at the third air outlet 13. The first micro-perforated plate, the second micro-perforated plate and the third micro-perforated plate are provided with a plurality of ventilation holes. When the air flow is blown out from the plurality of ventilation holes, the air flow is dispersed and becomes soft, thereby achieving a better windless air outlet effect.

[0070] It can be seen from the above embodiments that the third air outlet 13 is not necessary, and it is obvious that only one return air outlet 14 may be provided to introduce external air into the air outlet duct through the return air outlet 14 .

[0071] See also Fig.14In the third embodiment of the present invention, on the basis of the above-mentioned first embodiment, the housing 10 is further provided with a return air port 14, and the return air port 14 is adjacent to the front end of the volute 60 and is connected to the air outlet duct. When the user needs windless air supply, the user can choose to open the return air port 14, and the external air enters the air outlet duct from the third air outlet 13 to mix with the outlet air flow, and the mixed air flow is blown out from other air outlets. On the one hand, the outlet air temperature is slightly increased, the wind speed is reduced, and the outlet air is softer and more comfortable, achieving a windless effect; on the other hand, the outlet air volume can be increased. When the user needs conventional air supply, the user can choose to close the return air port 14.

[0072] See also Fig.14 and Fig.15 Here, in order to facilitate the user to switch between the normal air outlet mode and the windless mode, the front end of the volute 60 is provided with an air outlet connecting the return air port 14 and the air outlet duct; a third guide plate 40c is movably installed at the air outlet, and the third guide plate 40c is used to open or close the air outlet.

[0073] See also Fig.14 and Fig.15 As for the activity mode of the third guide plate 40c, the third guide plate 40c can be rotatably connected to the air outlet, and the third guide plate 40c has an unfolded state in which it rotates toward the return air outlet 14 to open the air outlet, and a wind-blocking state in which it rotates in the opposite direction to cover the air outlet.

[0074] Specifically, the third guide plate 40c can be rotatably connected to the inner edge or outer edge of the air outlet, as long as the third guide plate 40c can be rotated and opened toward the air outlet, so that when the third guide plate 40c is in the unfolded state, external air can flow from the return air outlet 14 to the inner air outlet.

[0075] See also Fig.14 and Fig.16 Here, it is also considered that when the user switches between the conventional air outlet mode and the multi-faceted windless mode, the third guide plate 40c and the first guide plate 40a need to be controlled to rotate one by one. If a rotating structure is provided for each guide plate, it will inevitably take up a large space and increase the cost. Therefore, it is preferred that the third guide plate 40c is connected to the first guide plate 40a through a third linkage structure. When the first guide plate 40a opens the vent, the linkage structure drives the third guide plate 40c to open the vent. The linkage structure is relatively common in the current market and is not listed in detail here.

[0076] See also Fig.17 and Fig.18As for the activity mode of the third guide plate 40c, the third guide plate 40c can be slidably installed on the volute 60, and the third guide plate 40c has a wind-blocking state of sliding to block the air outlet, and a receiving state of sliding to open the air outlet.

[0077] Specifically, the third guide plate 40c and the volute 60 can cooperate through the groove track structure, so that the third guide plate 40c can slide back and forth to switch between the wind blocking state and the storage state. In particular, when the third guide plate 40c is in the storage state, the third guide plate 40c is not likely to interfere with other structures inside the housing 10, and is not likely to block the return air flow.

[0078] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
