[0040] The invention provides a cabinet machine.

[0041] In one embodiment of the present invention, Figure 7 and Fig. 9 As shown, the cabinet includes a casing 100, in which a main air duct 110 and an auxiliary air duct 120 are provided, as well as a main air port 111 corresponding to the main air duct 110 and an auxiliary air port 121 corresponding to the auxiliary air duct 120. The air guide direction of the auxiliary air duct 120 is inclined downward, and the main air port 111 and the auxiliary air port 121 discharge air independently to form a first flow path flowing through the main air duct 110 and discharging air from the main air port 111, and a second flow path flowing through the auxiliary air duct 120 and discharging air from the auxiliary air port 121. In heating mode, the first flow path and the second flow path are both connected; in non-heating mode, the first flow path is connected and the second flow path is cut off.

[0042] In the technical solution of the present invention, in the heating mode, the first flow path and the second flow path are both connected, so that the cabinet air is discharged through the first flow path and the second flow path at the same time. Since the second flow path passes through the auxiliary air duct 120 that guides the air downward, the airflow flowing out of the auxiliary air outlet 121 is inclined downward, so that the airflow flowing out of the cabinet can flow toward the ground. Subsequently, under the tendency of its own upward action, the hot air can be fully diffused in the height direction of the indoor environment, so that the hot air is fully diffused in various areas of the indoor environment. In addition, under the action of the wall effect, the hot air flowing to the ground can flow along the ground, so that the hot air can be more efficiently diffused in the indoor environment. As a result, the temperature of the indoor environment can more efficiently reach the temperature set by the user, which can improve the temperature regulation effect and comfort of the air conditioner, thereby improving the heating comfort of the cabinet.

[0043] It can be understood that the air conditioner has a heating mode, a cooling mode, a dehumidification mode, and an air supply mode, and the non-heating mode is a mode other than the heating mode. In the non-heating mode, the second flow path of the cabinet is cut off, so that the cabinet only discharges air through the first flow path. The air outlet direction of the first flow path can be adaptively adjusted according to different modes to ensure the working performance of the cabinet in the non-heating mode.

[0044] Furthermore, in this embodiment, if Figure 7 and Fig. 9 As shown, the secondary air outlet 121 is located below the main air outlet 111. In this way, the secondary air outlet 121 is located in the lower area of ​​the cabinet and can be closer to the ground, thereby shortening the path of the airflow from the secondary air outlet 121 to the ground, and enabling the airflow to have a certain velocity component in the downward direction after reaching the ground, which is beneficial for the airflow to diffuse along the ground, so as to promote the uniform distribution of hot air in the room.

[0045] Furthermore, in this embodiment, if Figure 7 and Fig. 9 As shown, the main air duct 110 and the auxiliary air duct 120 are correspondingly distributed in the up-down direction. At least in the heating mode, the main air duct 110 and the auxiliary air duct 120 are connected. The cabinet also includes a heat exchanger 500, and the heat exchanger 500 is arranged in the main air duct 110. In the heating mode, the airflow entering the cabinet can be divided into two parts after heat exchange with the heat exchanger 500, one part flows toward the main air port 111 as the first flow path, and the other part flows toward the auxiliary air duct 120, and finally flows out from the auxiliary air port 121 as the second flow path. In this embodiment, it is only necessary to set the heat exchanger 500 in the main air duct 110 so that the auxiliary air duct 120 can also receive the airflow exchanged with the heat exchanger 500. Even if the auxiliary air duct 120 is disconnected from the main air duct 110 in the non-heating mode, it will not cause heat waste of the heat exchanger 500. Of course, in other embodiments, the main air duct 110 and the auxiliary air duct 120 may not be connected to each other, and the heat exchanger 500 may be separately provided in the main air duct 110 and the auxiliary air duct 120 .

[0046] Furthermore, in this embodiment, if Figure 7 and Fig. 9 As shown, the main air outlet 111 has an upper air outlet 111a and a lower air outlet 111b distributed from top to bottom. In the heating mode, the upper air outlet 111a is open and the lower air outlet 111b is closed; in the non-heating mode, the upper air outlet 111a and the lower air outlet 111b are both open. In this way, in the heating mode, the airflow of the main air duct 110 flows out through the upper air outlet 111a. In addition, since the lower air outlet 111b is closed, it hinders the airflow of the main air duct 110, forcing the airflow of the main air duct 110 to flow downward to the auxiliary air duct 120, and finally flows out through the auxiliary air outlet 121. Thus, the air volume of the auxiliary air outlet 121 can be guaranteed, so as to ensure that the auxiliary air outlet 121 has enough hot air to flow toward the ground. It should be noted that a grille can be set between the upper air outlet 111a and the lower air outlet 111b as a distinction, or they can be connected to form different parts of a long strip air outlet distributed in the up and down directions.

[0047] In one embodiment, please refer to Figures 4 to 7 , the upper air vent 111a and the lower air vent 111b are provided with independent vertical guide plates 210, and the upper air vent 111a and the lower air vent 111b can be opened or closed independently by the corresponding vertical guide plates 210. Specifically, Figure 5 As shown, in the heating mode, the upper vertical guide plate 210 is opened, and the lower vertical guide plate 210 is closed, so that the upper air vent 111a is opened, the lower air vent 111b is closed, and the main air duct 110 directly discharges air only through the upper air vent 111a; Figure 4As shown, in the non-heating mode, the two vertical guide plates 210 are opened, so that the main air outlet 111 is opened as a whole, and the main air duct 110 can directly discharge air through the main air outlet 111 as a whole. Figure 3 As shown, in the shutdown state, the two vertical guide plates 210 are closed to close the main air outlet. On this basis, as shown in FIG. Figure 6 As shown, in order to protect the vertical guide plate 210, a damper 300 may be additionally provided on the outside, and the main air outlet 111 may be covered by double closure of the damper 300 and the vertical guide plate 210. In addition, a damper 300 is provided at the auxiliary air outlet 121, and the auxiliary air outlet 121 may be switched on and off by opening and closing the damper 300.

[0048] In one embodiment, if Figure 1 and Figure 2 As shown, the cabinet further includes a damper 300. In the heating mode, the lower air outlet 111b is covered by the damper 300, and the upper air outlet 111a is exposed. It can be understood that the damper 300 is movably connected to the housing 100. By driving the damper 300 to move, the lower air outlet 111b can be opened and closed. When the damper 300 moves to a position relative to the lower air outlet 111b to cover the lower air outlet 111b, the lower air outlet 111b is closed. When the damper 300 moves away from the lower air outlet 111b, the lower air outlet 111b is exposed, and the lower air outlet 111b can be opened.

[0049] In one embodiment, if Figure 2 As shown, the main air outlet 111 is provided with a vertical guide plate 210, and the vertical guide plate 210 can open or close the main air outlet 111. The damper 300 is provided and is vertically movably connected to the housing 100. In the heating mode, the damper 300 covers the lower air outlet 111b; in the non-heating mode, the damper 300 covers the auxiliary air outlet 121. In this embodiment, the vertical guide plate 210 extends from the top side of the main air outlet 111 to the bottom side, and can open and close the main air outlet 111 as a whole, and the damper 300 can move up and down along the housing 100, and choose to cover one between the auxiliary air outlet 121 and the lower air outlet 111b. Specifically, when the cabinet is turned off, the damper 300 is located at the auxiliary air outlet 121, and the vertical guide plate 210 is in a closed state to achieve the closure of the main air outlet 111 and the auxiliary air outlet 121; when the cabinet is started in a non-heating state, such as Figure 2 As shown in (a), the damper 300 is maintained in a state of closing the auxiliary air outlet 121, and the vertical guide plate 210 is opened, so that the main air outlet 111 is opened; when the cabinet is started in the heating state, as shown in Figure 2As shown in (b), the damper 300 moves upward to the lower air port 111b, so that the auxiliary air port 121 is opened, and at the same time the vertical guide plate 210 is opened, so that the upper air port 111a is opened, so that air is discharged through the upper air port 111a of the main air port 111 and the auxiliary air port 121 at the same time. In this way, the structure of the cabinet can be simplified, and the control logic is simple, which is conducive to improving the manufacturability of the cabinet.

[0050] In one embodiment, if Figure 1 As shown, there are three dampers 300, and all of them are laterally movably connected to the housing 100, and the three dampers 300 are respectively arranged corresponding to the auxiliary air outlet 121 and the upper air outlet 111a and the lower air outlet 111b of the main air outlet 111. In this way, the three dampers 300 can independently open and close the auxiliary air outlet 121, the upper air outlet 111a and the lower air outlet 111b. Specifically, when the cabinet is turned off, the three dampers 300 all block the corresponding air outlets so that the three air outlets are all closed; when the cabinet is started in non-heating mode, the upper and middle dampers 300 are opened to open the upper air outlet 111a and the lower air outlet 111b correspondingly, so that the main air outlet 111 is opened as a whole, and the lower damper 300 remains in a closed state, so that the auxiliary air outlet 121 is closed; when the cabinet is started in heating mode, the upper and lower dampers 300 are opened to open the upper air outlet 111a and the auxiliary air outlet 121 correspondingly, and the middle damper 300 remains in a closed state, so that the lower air outlet 111b is closed.

[0051] In one embodiment, if Fig. 9 As shown, the main air duct 110 is provided with a swing blade 220 near the main air outlet. In the heating mode, the swing blade 220 has a downward wind guide angle, and the inclination angle is preferably 30 to 60 degrees. In this way, the air outlet of the cabinet can be directed downward as a whole, which can promote the flow of air to the ground, so that the hot air can be more efficiently diffused in the indoor environment, thereby further improving the heating comfort of the cabinet. In the non-heating mode, Figure 7 As shown, the wind guide angle of the horizontal swing leaf 220 can be driven toward the front of the main air outlet 111, and at the same time, the vertical wind guide member can be driven to swing back and forth to increase the horizontal air supply range of the cabinet. In particular, in the cooling mode, the horizontal swing leaf 220 can be driven to swing upward, so that the horizontal swing leaf 220 has an upward wind guide angle, so that the cold air first flows toward the upper area of ​​the room, so that the airflow forms a ceiling airflow, avoids the cold air blowing directly on people, and improves the comfort of air supply. Subsequently, under the trend of its own sedimentation, the cold air can be fully diffused in the height direction of the indoor environment, so that the cold air is fully diffused in various areas of the indoor environment, which is conducive to slowing down the sedimentation of the cold air and can avoid the cold air from sinking in the lower area of ​​the room.

[0052] In one embodiment, if Figure 6 , Figure 7 , Fig. 9 and Fig.11 As shown, the cabinet includes an air duct component 130 disposed in the housing 100, the air duct component 130 is formed with an air passage cavity 131, the main air duct 110 includes the air passage cavity 131, the air passage cavity 131 is arranged close to the main air port 111, the auxiliary air duct 120 is arranged in the air duct component 130 and is located at the lower side of the air passage cavity 131, and the auxiliary air duct 120 is connected with the air passage cavity 131 at least in the heating mode. In this way, the auxiliary air duct 120, the air passage cavity 131, and the structure of the auxiliary air duct 120 connecting the main air duct 110 can all be formed on the air duct component 130, and the air duct component 130 can be formed separately from the surface frame, panel and other structures of the housing 100, which is conducive to reducing the complexity of the relevant molds of the housing 100, thereby facilitating the production and processing of the cabinet. In addition, when the lower air outlet 111b is blocked, there is a gap between the air duct component 130 and the corresponding blocking structure (including the vertical guide plate 210 and the damper 300) for the air flow to flow downward, so as to force the air flow to flow toward the auxiliary air duct 120. Without loss of generality, the air duct component 130 is provided with a plurality of air passage cavities 131 from top to bottom, wherein the auxiliary air duct 120 can be connected to the lowermost air passage cavity 131 in the heating mode. In this way, when the air duct component 130 is injection molded, it is not easy to deform at the air passage cavity 131, which can reduce the difficulty of production and processing of the air duct component 130, and can also ensure the structural stability of the air duct component 130.

[0053] In one embodiment, if Figure 7 and Fig. 9 As shown, the auxiliary air duct 120 is fixedly provided with an air guide plate 122 that is tilted downward in the air outlet direction. In this way, in the heating mode, the hot air flowing through the auxiliary air duct 120 can be discharged from the auxiliary air outlet 121 in a tilted downward direction through the guidance of the air guide plate 122, so that the hot air can flow toward the ground to promote the diffusion of the hot air in the room. Of course, in other embodiments, the auxiliary air duct 120 can also be a structure that is tilted downward as a whole.

[0054] Further, in this embodiment, the air guide plates 122 are distributed in multiple intervals along the vertical direction, and each of the air guide plates 122 is spaced apart from the wall of the auxiliary air duct 120 at one end away from the auxiliary air outlet 121. In this way, a downwardly inclined air guide channel can be formed between each two adjacent air guide plates 122. Without loss of generality, the wall of the bottom side of the auxiliary air duct 120 is set to a structure inclined in the same direction, and the lowest air guide plate 122 is spaced apart from the wall, and a downwardly inclined air guide channel is also constructed. In this way, multiple air guide channels are constructed to enhance the guiding effect on hot air. In addition, the end of the air guide portion away from the air outlet is spaced apart from the wall of the auxiliary air duct 120 to form a channel for the hot air to descend, so that the hot air can descend to the lowest air guide channel to ensure the uniformity of the air outlet of the auxiliary air outlet 121, so that the hot air flowing out of the air outlet can be as close to the ground as possible. Of course, in other embodiments, it is also possible that a through hole is provided on the air guide plate 122 for air flow to pass through.

[0055] In one embodiment, if Figures 7 to 10 As shown, there is a connecting passage 140 between the secondary air duct 120 and the air passage cavity 131, and the connecting passage 140 is provided with a movable baffle 400. In the non-heating mode, the baffle 400 is located at the connecting passage 140, which can block the airflow of the main air duct 110 from entering the secondary air duct 120. In the heating mode, the baffle 400 leaves the connecting passage 140, so that the connecting passage 140 is opened as a whole.

[0056] Specifically, if Figure 8 and Fig.10 As shown, the baffle 400 is rotatably connected to the side of the connecting port 140 away from the secondary air port 121. In the non-heating mode, the baffle 400 overlaps the uppermost air guide plate 122; in the heating mode, the baffle 400 overlaps the wall of the secondary air duct 120. It can be understood that the width of the baffle 400 is roughly equal to the distance between the side of the air guide plate 122 away from the secondary air port 121 and the wall of the secondary air duct 120, so that the baffle 400 can rotate without interference. In this way, in the non-heating mode, the secondary air duct 120 above the uppermost air guide plate 122 is still connected to the main air duct 110, but the space of this part is limited, and the air volume flowing here is very small and can be almost ignored, and the external secondary air port 121 is also closed, so it will not affect the working performance of the cabinet in the non-heating mode.

[0057] In this embodiment, the main part of the auxiliary air duct 120 and the main air duct 110 can be switched between on and off by driving the baffle 400. When the cabinet is turned off or in non-heating mode, the baffle 400 covers the connecting port 140, so that the main part of the auxiliary air duct 120 is disconnected from the main air duct 110 to prevent the air flow from flowing to the main part of the auxiliary air duct 120, thereby ensuring the air volume of the main air port 111; in the heating mode, the baffle 400 is opened, so that the auxiliary air duct 120 is connected to the main air duct 110 as a whole, so that the air flow of the main air duct 110 can flow downward to the auxiliary air duct 120. Furthermore, the baffle 400 can stably block the airflow toward the main part of the auxiliary air duct 120 at the connecting port 140 in the heating mode. When the power is turned off or in the non-heating mode, the baffle 400 overlaps the wall of the auxiliary air duct 120 and occupies a small space, which will not affect the flow of the airflow. Moreover, the baffle 400 is set downward and will not be disturbed by the airflow.

[0058] Of course, in other embodiments, a baffle connected to the casing 100 and movable horizontally may be provided, and when the cabinet is turned off or in non-heating mode, the baffle covers the entire connecting opening 140, and in heating mode, the baffle moves toward the side where the heat exchanger 500 is located to expose the connecting opening 140; or, a baffle is provided on each side of the connecting opening 140, and in non-heating mode, both baffles are overlapped with the top air guide plate 122, and in heating mode, one baffle is overlapped with the wall of the auxiliary air duct 120, and the other baffle is overlapped with the wall of the air cavity.

[0059] The present invention also proposes an air conditioner, which includes a cabinet. The specific structure of the cabinet refers to the above-mentioned embodiment. Since this air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
