1 to 3, the present invention proposes an air conditioner cabinet 100, including:

Housing 10, the housing 10 includes a casing (not marked) and a volute 19 accommodated in the casing, the casing specifically includes a front casing 11, a rear casing 13 and a base 12 that are detachably connected, through the front casing 11 and the rear casing 13 is detachably connected, and then installed on the base 12, so that the installation and disassembly of the air-conditioning cabinet 100 are relatively convenient. The shape surrounded by the shell is generally square cylinder.

An air duct is formed in the casing 10, specifically, the main part of the air duct is formed in the volute 19, a fan 30 is installed in the volute 19 (ie, in the air duct), and an air duct is formed between the rear shell 13 and the volute In the air inlet part, a heat exchanger 50 is installed between the rear shell 13 and the volute 19 .

In this embodiment, the rear shell 13 is provided with an air inlet 10a communicating with the air duct, and external air enters into the air duct through the air inlet 10a. The air conditioner cabinet is also provided with a dust-proof filter (not shown) for filtering. The filter is located in the casing 10 and covers the air inlet 10a to ensure the cleanliness of the air entering the air duct. At the same time, a dust sensor (not shown) is also set to detect the dust degree of the dust filter to prevent the dust in the dust filter from passing through and blocking the air duct.

The air entering the air-conditioning cabinet is driven by the fan 30, passes through the heat exchanger 50 for heat exchange, and blows out to the outside through the air duct to the air outlet structure 90. The heat exchanger 50 is a plate heat The heat exchanger 50 can increase the heat exchange area, and at the same time, the plate heat exchanger 50 is convenient for processing and maintenance.

The air inlet 10a is set on the plate heat exchanger 50 to increase the heat exchange area, so as to ensure that the air entering the air duct passes through the heat exchanger 50 for heat exchange. The heat exchanger 50 is installed and fixed in the shell, and in this embodiment, it is specifically fixed and installed by providing a fastening device on the rear shell 13 such as a bolt connection piece. A water receiving tray 51 is installed at the lower end of the heat exchanger 50 for receiving condensed water, and the water receiving tray 51 is arranged in a rectangular shape.

The air-conditioning cabinet 100 is provided with an air outlet device (not marked), and the air outlet device is fixed on the housing 10. The air outlet device includes three air outlet structures 90 arranged at intervals in the horizontal direction, and two adjacent A wind tunnel 10b is provided between the air outlets 91a of the wind outlet structure 90, and the wind tunnel 10b penetrates the casing along the front and rear directions.

The present application is also provided with an air guiding cylinder 17, which is supported between the casing 10 and the air outlet device, specifically, one end of the air guiding cylinder 17 is connected to the volute 19, and the other end is connected to the casing , the air guide tube 17 communicates with the three air outlet structures 90 and the air duct.

The technical solution of the present invention adopts three air outlet structures 90 and provides double air tunnels 10b. When the air conditioner cabinet 100 is running, external air enters the air duct and flows out from the air outlets 91a of the three air outlet structures 90. The air velocity at the front end of the wind tunnel 10b adjacent to the air outlet 91a is relatively fast and the pressure is low. There is a pressure difference between the rear end of the wind tunnel 10b and the front end of the wind tunnel 10b, and the air at the rear end of the wind tunnel 10b moves from back to front, and Converge with the air flowing out of the three air outlets 91a, thereby greatly increasing the air output of the air conditioner cabinet 100. The air outlets 91a of the three air outlet structures 90 are individually closed and opened independently, so as to realize the effects of regional air supply and temperature control. When the three air outlet structures 90 work at the same time, the three air outlets 91a and the two air tunnels 10b form five air flow channels, and a turbulence effect is formed between the five air flow channels, which can achieve the effect of rapid temperature control and a wider control area.

In addition, when the air conditioner cabinet 100 is in cooling operation, hot air with a relatively high indoor temperature is blown out from the wind tunnel 10b, and the hot air mixes with the cold air to increase the temperature of the air at the front side of the housing 10, thereby increasing the air outlet efficiency of the air conditioner cabinet 100. softness, thereby improving the use comfort of the air conditioner cabinet 100. When the air conditioner cabinet 100 is in heating operation, the three air outlets 91a blow hot air with a higher temperature forward, and the cold air with a lower indoor temperature is blown out from the wind tunnel 10b. The temperature of the air improves the softness of the air outlet of the air conditioner cabinet 100 , thereby improving the use comfort of the air conditioner cabinet 100 .

In addition, the air-conditioning cabinet 100 is provided with an air guide tube 17 on the flow path of the air blown from the air channel to the air outlet structure 90, and the air guide tube 17 regulates the wind flowing from the air channel to the air outlet structure 90. In the existing air-conditioning cabinet, the air in the air-conditioning cabinet directly enters the air outlet structure through the air duct and blows out to the outside. The air-conditioning cabinet 100 of the present invention can overcome the wind blowing from the air duct to the air outlet structure 90 due to the irregular shape of the air duct. The occurrence of turbulent flow causes the problem of unstable wind speed output by the air outlet structure 90 , thus improving the air outlet effect of the air conditioner cabinet 100 .

In order to achieve a better air conditioning effect, the shape of the air guiding cylinder 17 in this embodiment is generally in the shape of a truncated cone, and an air guiding chamber communicating with the air duct is formed inside the air guiding cylinder 17, and the diameter of the air guiding chamber is within the The air flow direction from the air duct to the air outlet structure 90 gradually decreases. The air guide tube 17 of this embodiment can be produced by integral injection molding, so that the inner cavity of the air guide tube 17 has a smooth wall surface, and the wind resistance generated in this way is small. During the process of the wind blowing to the air outlet structure 90 in the part of the air duct located in the volute 19, through the adjustment function of the air guide tube 17, the vortex of the wind blown by the fan 30 due to the irregular shape of the air duct can be eliminated, and the wind guide The cylinder 17 gathers and speeds up the wind blown from the air duct to the air outlet structure 90, so that the wind speed of the air blown out by the air outlet structure 90 is stable, and the speed is also increased, so that the air outlet effect of the air conditioner cabinet is further improved.

Referring to FIG. 1 , in this embodiment, the wind tunnel 10b is arranged in strips extending in the vertical direction. In the process of forming the wind tunnel 10b, the more the curved surface is, the easier it is to form stress concentration on the curved surface, and microcracks will be generated inside. Because the wind tunnel 10b needs to pass the wind continuously, the microcracks will be exposed after a long period of use. Afterwards, it will become unstable and expand, causing the casing 10 to be damaged. Therefore, the wind tunnel 10b is elongated, and it only produces curved surfaces at the bends connected up and down, so as to enhance the service life of the casing 10 . The elongated shape extending up and down also facilitates the processing and molding of the casing 10 . At the same time, through the elongated wind tunnel 10b, a relatively high pressure difference can be formed at the front and rear ends of the wind tunnel 10b, and the wind force can be sent out from the wind tunnel 10b in a relatively concentrated manner.

Of course, in another embodiment, the wind tunnel 10b is arranged in a circle extending along the up and down direction. Through the wind tunnel 10b arranged in a circular shape, wind resistance can be reduced and air passing performance can be improved.

Further, the upper cavity wall of the wind tunnel 10b is set in a smooth curved surface.

When the air passes through the wind tunnel 10b, the wind resistance mainly comes from the bending of the cavity wall of the wind tunnel 10b, and the wind resistance of the wind tunnel 10b can be reduced by setting the upper cavity wall as a smooth curved surface. Certainly, the lower cavity wall of the wind tunnel 10b may also be set as a smooth curved surface to reduce wind resistance.

Here, both the rear inlet and the front outlet of the wind tunnel 10b are arranged in a flared shape. Both front and rear are arranged in a flared shape, and when the air passes through the flared wind tunnel 10b, when the air flows through the wind tunnel 10b, the passing performance is improved and the air volume is increased.

In addition, the wind tunnel 10b is also provided with an opening and closing device for the wind tunnel 10b. Specifically, a longitudinal cover plate (not shown) may be used to drive the longitudinal cover plate to rotate in the wind tunnel 10b through a motor to block or open the wind tunnel 10b. The longitudinal cover plate is also set here for consideration To control the air volume, when the air volume is too large, one of the wind tunnels 10b may be considered to be sealed and closed.

Referring to Figure 2 and Figure 3, the upper end of the air guide tube 17 is formed with three air outlet openings 171 that communicate with the air duct, and each of the air outlet structures 90 communicates with one of the air outlet openings 171 . That is to say, the wind blown out of the air duct in this embodiment is regulated by the air guide tube 17, and is divided into three paths and enters into three air outlet structures 90 respectively. In this way, the mutual interference effect of adjacent air outlet structures 90 is smaller during the working process, and each outlet The wind speed of the wind output by the wind structure 90 is more stable. Specifically, each of the air outlet structures 90 includes an air outlet frame 91, and the air outlet frame 91 has an air outlet 91a communicating with the air duct. In this embodiment, the air outlet frame 91 is also connected to a rotating mechanism (not shown in the figure). ), the rotating mechanism drives the air outlet frame 91 to rotate relative to the casing 10 .

The rotating mechanism of this embodiment can be a structure in which the motor, the driving gear and the driven gear or rack cooperate, wherein the driving gear is connected to the output shaft of the motor, the driving gear meshes with the driven gear or the rack, and the driven gear or the rack The air outlet frame 91 is fixedly connected.

In an embodiment of the present invention, the air outlet frame 91 is arranged in the housing, specifically, an air outlet 15 is formed on the upper part of the housing (ie, the front housing 11 and the rear housing 13), and the air outlet 15 is provided with three air outlet units 151 arranged at intervals, and the gap between adjacent air outlet units 151 forms the wind tunnel 10b;

Each of the air outlet units 151 is formed with an accommodating cavity (not marked), and the cavity wall of each accommodating cavity is provided with a relief opening 151a, and the air outlet frame 91 is located in the accommodating cavity, and The air outlet 91a of the air outlet structure 90 communicates with the relief opening 151a in the air outlet state. That is, three air outlet units 151 are formed on the upper end of the casing, and each air outlet structure 90 is correspondingly accommodated in an accommodating chamber of an air outlet unit 151 , and the air outlet frame 91 rotates in the accommodating chamber. When the wind needs to be blown out, the rotating mechanism is driven to rotate, and the air outlet frame 91 is driven so that the air outlet 91a faces the relief opening 151a, and the external air enters through the air inlet 10a of the air duct, and is driven by the fan 30 to the air outlet in the air duct. The heat exchanger 50 exchanges heat, and then blows out through the air outlet 91a and the relief port 151a. When it needs to be closed, the air outlet frame 91 is driven to rotate by the rotating mechanism, so that the air outlet 91a and the relief port 151a are in a non-conductive state, and the air outlet structure 90 can be closed.

In this embodiment, the relief opening 151 a is provided at the front case 11 , and the air inlet 10 a communicating with the air duct is provided at the rear case 13 .

When the air-conditioning cabinet 100 is installed, in order to make the air flow path in the air-conditioning cabinet more reasonable, the air inlet 10a is arranged on the rear shell 13 of the air-conditioning cabinet 100, and the relief port 151a is arranged on the upper part of the front shell 11, so Setting also makes the shell of the air conditioner cabinet 100 more beautiful. The air inlet 10a corresponds to the plate heat exchanger 50, and is generally arranged in a rectangular shape. An air inlet grill is arranged at the air inlet 10a, and the air inlet grill generally consists of horizontally arranged air guide strips and vertically arranged reinforcing ribs. The air inlet 10a arranged in this way can adjust the direction of the air inlet, and the setting of the reinforcing rib can also strengthen the structural strength of the air inlet grille.

Referring to FIG. 1 , in this embodiment, the air outlet 15 is arranged in a wedge shape. Because the wind tunnel 10b is arranged on the air outlet part 15, the air outlet part 15 is arranged in a wedge shape, so that the length of the wind tunnel 10b from the lower end to the upper end is gradually reduced. Therefore, when the air in the air conditioner cabinet 100 is circulating, it can be sucked in from the side of the wind tunnel 10b, increasing the air intake.

In this embodiment, the air outlet frame 91 is arranged in a cylindrical shape, the side wall of the air outlet frame 91 has a shutdown surface and an air outlet surface, the air outlet 91a is arranged on the air outlet surface, and the lower end of the air outlet frame 91 A through-hole 91b communicating with the air duct is provided.

The side wall of the cylindrical air outlet frame 91 forms the air outlet surface and the shut-off surface, and the rotating mechanism drives the cylindrical air outlet frame 91 so that the air outlet 91a faces the relief opening 151a to complete the air outlet structure 90 The opening of the air outlet structure 90 can be completed by driving the shutdown surface to block the relief opening 151a.

Of course, the air outlet frame can also be set in a bracket type (not shown), such as setting a plurality of horizontal mounting columns and vertical mounting columns, one of which forms a rotation axis, and a plurality of horizontal mounting columns are radially fixed on the The two ends of the vertical installation column and the ends of the plurality of horizontal installation columns away from the vertical installation column are connected with circular arc connectors. Then use several vertical installation columns as connectors to connect the upper and lower ends to form a bracket-type air outlet frame. As a result, the gap between the horizontal mounting columns at the lower end forms a through hole. Then, a windshield is set between the vertical installation columns, and the windshield is set adjacent to the air outlet, and the air outlet is formed by two adjacent vertical installation columns. When the air outlet structure is in the closed state, the rotating mechanism drives the air outlet frame to rotate so that the windshield blocks the relief opening. When the indoor air conditioning process does not require one of the three air outlet structures to discharge air, the rotating mechanism drives the corresponding air outlet frame to rotate, so that the windshield can face the relief opening during the rotation of the air outlet frame. The closing operation of the air outlet structure is realized, so that the overall structure of the air outlet structure 90 is simplified, and the cost of the air conditioner cabinet is reduced.

In this way, the air outlet frame 91 can be arranged outside the housing 10 and fixed on the upper end of the housing 10 .

The air outlet frame 91 of this embodiment is in the shape of a cylinder as a whole, so that the process of the rotating mechanism driving the air outlet structure 90 is smoother, and the inside of the air outlet frame 91 has a cylindrical inner cavity, and the fan 30 drives air through the air duct of the housing 10 After entering the inner cavity of the air outlet frame 91 , it turns in the cylindrical inner cavity and blows out through the air outlet 91 a on the side wall, so that the air outlet efficiency of the air outlet structure 90 can be improved.

The air outlet 91a is also provided with longitudinal guide vanes 913 , and the longitudinal guide vanes 913 and the transverse air guide plates 911 form an air outlet grille. Through the arrangement of the longitudinal guide vanes 913, the range of sweeping wind in the left and right directions of the air outlet structure 90 can be increased. In this embodiment, through the cooperation of the horizontal air guide plate 911 and the longitudinal guide vanes 913, the air outlet structure 90 has a variety of air outlets.
