1 to 4, the present invention proposes an air conditioner cabinet 100, including:

Housing 10, the housing 10 includes a detachably connected front shell 11, a rear shell 13 and a base 12, through the detachable connection of the front shell 11 and the rear shell 13, and then installed on the base 12, so that the air conditioner cabinet 100 The installation and disassembly are more convenient. The casing 10 is generally arranged as a square cylinder.

An air duct is formed in the casing 10 , that is, an air duct is formed between the front shell 11 and the rear shell 13 , and a fan 30 and a heat exchanger 50 are installed in the air duct.

The air duct is mainly formed inside the casing 10, and the external air enters the air duct through the air inlet 10a of the air duct, and the external air enters before the heat exchanger 50 in the air duct through the air inlet 10a. A dust filter (not shown) is used for filtering. The dust filter is located in the housing 10 and covers the air inlet 10a of the air duct 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 duct is driven by the blower fan 30 and passes through the heat exchanger 50 for heat exchange. The heat exchanger 50 is a plate heat exchanger 50, and the heat exchange area can be increased through the plate heat exchanger 50. At the same time, the plate heat exchanger 50 is convenient for processing and maintenance.

The air inlet 10a of the air duct is set on the plate heat exchanger 50 to increase the heat exchange area, so as to ensure that all 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 casing 10 , specifically, in this embodiment, it is fixed and installed by providing a fastening device such as a bolt connection piece on the rear casing 13 . 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 lateral direction. The air outlet structures 90 are all in communication with the air ducts, and a wind tunnel 10b is provided between the air outlets 91a of two adjacent air outlet structures 90 , and the wind tunnel 10b runs through the casing 10 along the front and rear directions.

Please refer to Figure 2 and Figure 4 further, the air outlet structure 90 includes an air outlet frame 91 connected to the air duct, the air outlet frame 91 is provided with a pillow block 915, the housing 10 is fixed with a driving motor 95, the pillow block 915 and the driving motor 95 The output shaft is connected by transmission to drive the air outlet frame 91 to rotate relative to the casing 10 . Specifically, a pillow block 915 is fixed on the upper surface of each air outlet frame 91 , and the axis of each pillow block 915 is arranged in a vertical direction. Correspondingly, three driving motors 95 are fixed inside the housing 10, and there is a one-to-one correspondence between the three driving motors 95 and the three-axis table 915, and transmission cooperation can be carried out so that the rotation of the output shaft of the driving motor 95 drives the rotation of the pillow table 915. , and then use the rotation of the pillow block 915 to drive the air outlet frame 91 to rotate.

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 .

Furthermore, in the technical solution of the present invention, a pillow block 915 is fixed to the air outlet frame 91 of each air outlet structure 90, and a drive motor 95 is fixed to the housing 10, so that the drive motor 95 and the pillow block 915 can be connected one by one. Correspondingly carry out transmission cooperation, so that each pillow block 915 rotates to drive each air outlet structure 90 to rotate relative to the housing 10, thereby realizing the multi-angle rotation and air outlet function of each air outlet structure 90, further expanding The air outlet area of the air conditioner cabinet 100 is increased, so that the temperature of the indoor air can reach the preset temperature value more effectively and quickly, and the comfort of the user is increased.

Please refer to Fig. 4 again, the air outlet frame 91 includes a circular top cover plate 917 and a side wall extending downward along the outer edge of the top cover plate 917, the side wall is provided with an air outlet 91a, and the pillow block 915 is arranged on the top cover plate The middle of the 917. Specifically, the air outlet frame 91 is roughly cylindrical, and the pillow block 915 is fixed at the middle position of the top cover plate 917 of the air outlet frame 91, so that the axis of the pillow block 915 coincides with the axis of the air outlet frame 91, so that Effectively reduce the friction and collision between the air outlet frame 91 and surrounding components, make the rotation of the air outlet frame 91 more stable, and also make the structure of the air conditioner cabinet 100 more stable, thereby effectively improving the air outlet comfort of the air conditioner cabinet 100, Improve user experience.

Please refer to FIG. 6 , a driving shaft hole 9151 is formed on the end surface of the pillow block 915 , and the output shaft of the driving motor 95 is inserted into the driving shaft hole 9151 . Specifically, the pillow block 915 is approximately cylindrical, and its lower end is fixed to the top cover plate 917 of the air outlet frame 91 , and its upper end surface is formed with a driving shaft hole 9151 . The shape and size of the drive shaft hole 9151 matches the shape and size of the output shaft of the drive motor 95. It can be understood that in order to make the output shaft of the drive motor 95 drive the pillow block 915 to rotate, and then drive the air outlet frame 91 to rotate, the drive shaft The hole 9151 can be a square hole, a rectangular hole, a waist-shaped hole, or some other reasonable and effective shapes. Like this, the transmission cooperation between the output shaft of the drive motor 95 and the drive shaft hole 9151 can be made more efficient, thereby reducing the need for the motor and air conditioner. The energy consumption of the cabinet machine 100 improves the energy efficiency level of the air conditioner cabinet machine 100 .

Please refer to FIG. 5 , the housing 10 is fixed with a positioning plate 93 , and the positioning plate 93 is provided with a positioning hole 931 , and the pillow block 915 passes through the positioning hole 931 and is connected to the output shaft of the driving motor 95 in transmission. Specifically, the positioning plate 93 is fixed on the upper part of the rear shell 13 , is arranged horizontally, and is located inside the casing 10 . The pillow block 915 of the air outlet frame 91 is accommodated in the positioning hole 931 of the positioning plate 93 . Therefore, it can be understood that when the drive motor 95 drives the air outlet frame 91 to rotate, the pillow block 915 can rotate in the positioning hole 931, and at this time, the side wall of the positioning hole 931 can support the side wall of the pillow block 915, The function of auxiliary is to keep the pillow block 915 in a vertical state during the rotation process, that is, the upper part of the air outlet frame 91 is always in a vertical state during the rotation process, so as to avoid the upper part of the air outlet frame 91 from rotating. During the process, the drive motor 95 is damaged due to deviation, thereby effectively ensuring the rotation and air outlet function of the air outlet frame 91.

Preferably, the driving motor 95 is fixed on the positioning plate 93. It can be understood that such an arrangement, on the one hand, can make the distance between the driving motor 95 and the pillow block 915 closer, thereby reducing the resistance arm at the free end of the output shaft of the driving motor 95. , to reduce the load on the drive motor 95, thereby reducing the energy consumption of the drive motor 95 and the air-conditioning cabinet 100; It is more compact and stable, thus providing further structural guarantee for the rotation of the air outlet frame 91 . In addition, such a setting also simplifies the internal structure of the air conditioner cabinet 100 , reducing the possibility of failure and the difficulty of maintenance.

It should be noted that, in some embodiments, what drives the air outlet frame 91 to rotate may also be some other rotating mechanism, for example: a motor, a driving gear and a driven gear or a gear rack, wherein the driving gear and the motor The output shaft is connected, the driving gear meshes with the driven gear or the rack, and the driven gear or the rack is fixedly connected to the air outlet structure 90.

Please refer to FIG. 1 again. 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.

In an embodiment of the present invention, the air outlet frame 91 is arranged in the housing 10. Specifically, an air outlet 15 is formed on the upper part of the housing 10, and the air outlet 15 is provided with three outlets arranged at intervals. Wind units 151, 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 structure 90 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 housing 10 , 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 wind needs to be blown out, the air outlet frame 91 is driven to make the air outlet 91a face the relief opening 151a through the rotating mechanism, and the external air enters through the air inlet 10a of the air duct, and the fan 30 is driven into 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 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. It can be understood that using the shutdown surface to block the relief opening 151a can effectively improve the airtightness of the casing 10 when the corresponding air outlet structure 90 is in the closed state, thereby effectively improving the air outlet capacity of other air outlet structures 90 in the open state. , to increase user comfort, and at the same time, the reduction of air leakage can also effectively improve the temperature regulation efficiency of the air conditioner cabinet 100 and reduce the energy consumption of the air conditioner cabinet 100 . In addition, such a setting can also prevent the air outlet structure 90 from being eroded by dust and moisture due to long-term exposure to the air when it is closed, ensure the integrity of the internal structure, and improve the quality of the air outlet when it is normally opened.

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 opening. 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 is simple, and the cost of the air conditioner cabinet is reduced.

Of course, in another embodiment of the present invention, the air outlet frame 91 of the air outlet structure 90 is arranged in a cylindrical shape, the lower end is provided with a through opening 91b, the side wall is provided with an air outlet 91a, and the air outlet 91a is provided with a horizontal air guide Plate 911, the horizontal wind deflector 911 is provided with multiple pieces horizontally, and the same side of the multiple horizontal wind deflectors 911 is rotatably connected with a connecting rod, and the connecting rod can be driven by a motor to pull the horizontal wind deflector 911 to swing up and down to realize Sweep the wind up and down of the air outlet 91a. The horizontal wind deflector 911 can not only guide the wind direction, but also block the air outlet 91a by closing the horizontal wind deflector 911 . 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. Mode, adapt to various needs of indoor air conditioning.

In this embodiment, the relief opening 151 a is disposed on the front side wall of the housing 10 , and the air inlet 10 a of the air duct is disposed on the rear side wall of the housing 10 .

When the air-conditioning cabinet 100 is installed, in order to make the setting of the air duct more reasonable, the air inlet 10a is arranged behind the housing 10 of the air-conditioning cabinet 100, and the relief port 151a communicates with the air outlet 91a of the air outlet frame 91, so , the relief port 151a is provided at the front of the casing 10 . Such setting also makes the casing 10 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.

When an air duct is formed in the housing 10 of the air conditioner cabinet 100, the air duct is formed by an air inlet cavity, and the fan 30 is also provided with one, and the three air outlet structures 90 are all communicated with the same air inlet cavity. For example, external air enters from the air inlet 10a of the air duct, is driven by the fan 30, passes through the heat exchanger 50, enters the air inlet cavity, enters the air outlet structure 90 through the through hole 91b at the lower end of the air outlet structure 90, and passes through the air outlet structure 90. The air outlet 91a of the air outlet structure 90 blows out. In the case of one air inlet cavity, the overall structure of the air conditioner cabinet 100 is simple and compact, and the cost is low.
