Specifically, in this embodiment, the cabinet air conditioner includes a housing 100, an air intake assembly, a heat exchange assembly 610, an air supply assembly 620, and an air guide assembly, where the air intake assembly, the heat exchange assembly 610, the air supply assembly 620, and the air guide assembly are all fixedly connected with the housing 100. The specific connection and positional relationship between the above-described components are described below. The casing 100 is arranged in a column shape along the up-down direction, the left side, the right side and/or the rear side of the casing 100 are provided with air inlets 130, and the air inlets 130 can extend along the height direction of the casing 100; an air outlet 110 is formed at the front side of the housing 100, the air outlet 110 extends along the height direction of the housing 100, and an air duct is formed between the air inlet 130 and the air outlet 110. The air inlet assembly may include an air inlet grille, a filter screen, etc., and is disposed on the housing 100 at a position corresponding to the air inlet 130 along the length direction of the air inlet 130. The heat exchange assembly 610 may include a heat exchanger 611, a heat exchanger 611 support, electric auxiliary heat, and the like, where the heat exchange assembly 610 is disposed in the air duct corresponding to the air outlet 110 along the height direction of the housing 100. The air supply assembly 620 may include a cross flow fan 621, a fan motor for driving the cross flow fan 621, etc., wherein the cross flow fan 621 is disposed in the air duct along the height direction of the housing 100. The air supply assembly 620 includes an air guide plate assembly 150, a shutter assembly, and a door assembly, etc., wherein the air guide plate assembly 150, the shutter assembly, and the door assembly are all disposed on the housing 100 at positions corresponding to the air outlet 110 along the length direction of the air outlet 110, so as to guide the air outlet direction of the cabinet air conditioner. The air deflection assemblies 150 are positioned between the louver assemblies and the door body assemblies, although the positions of the louver assemblies and the air deflection assemblies 150 may be adjusted according to actual needs in some implementations.
The door body assembly may include an upper door body assembly 310 and a lower door body assembly 320, and the upper door body assembly 310 and the lower door body assembly 320 are disposed at the air outlet 110 along the length direction of the air outlet 110; the upper door body assembly 310 and the lower door body assembly 320 are respectively and independently driven by different motors to independently control air supply; the upper door assembly 310 and the lower door assembly 320 may be located in the same working plane (the working plane is not an absolute plane, but only is used for illustrating the spatial positions of two groups of doors), or may be located in different working planes according to actual needs. At this time, the air outlet 110 is divided into an upper air outlet 111 and a lower air outlet 112, and the air supply is controlled by an upper door assembly 310 and a lower door assembly 320, respectively. By arranging the door body assembly as the upper door body assembly 310 and the lower door body assembly 320, the air supply condition of the upper and lower portions of the air outlet 110 can be adjusted according to actual needs. When the door body is a door body without air feeling, the upper door body assembly 310 and the lower door body assembly 320 can respectively realize air supply without air feeling of the upper air outlet 111 and the lower air outlet 112. Taking the door body as a non-wind-sensation door body as an example, when the lower door body assembly 320 is closed under a certain working condition, the non-wind-sensation air supply of the lower air outlet 112 and the traditional air supply of the upper air outlet 111 are realized. In this process, the wind wheel has a comparable air supply speed to the upper and lower air outlets 112, and the air outlet 112 is blocked, so that the air pressure at the lower part of the air duct gradually increases, and when the air pressure at the lower part of the air duct is greater than the air pressure at the upper part of the air duct, a part of the air flow at the lower part of the air duct flows to the upper part of the air duct, so that the air pressure at the upper part of the air duct increases, thereby increasing the air outlet speed of the upper air outlet 111 and increasing the air supply distance. Similarly, when the upper door assembly 310 is closed under a certain working condition, the air without the wind sense of the upper air outlet 111 and the conventional air of the lower air outlet 112 are realized. In this process, the wind wheel has a considerable air supply speed to the upper and lower air outlets, and the air outlet 111 is blocked, so that the air pressure at the upper part of the air duct gradually increases, and when the air pressure at the upper part of the air duct is greater than the air pressure at the lower part of the air duct, a part of the air flow at the upper part of the air duct flows to the lower part of the air duct, so that the air pressure at the lower part of the air duct increases, thereby increasing the air outlet speed of the lower air outlet 112 and increasing the air supply distance. Of course, when both the upper door assembly 310 and the lower door assembly 320 are closed to supply the air without the sense of wind, the wind pressure in the entire duct increases.
By arranging the upper door body assembly 310 and the lower door body assembly 320 independently of each other, the air supply of the upper part and the lower part of the air outlet are mutually independent, so that the air supply amounts of the upper part and the lower part of the cabinet air conditioner can be different, and a user can control the air supply amounts of the upper part and the lower part of the air conditioner according to the requirement, so as to meet the requirement of the user on the air supply amount; in addition, when the air volumes of the upper and lower parts of the cabinet air conditioner are different, it is indicated that the area of the upper door assembly 310 covering the upper air outlet is different from the area of the lower door assembly 320 covering the lower air outlet, that is, the effective areas of the upper air outlet and the lower air outlet are different; specifically, when the effective area of the upper air outlet is smaller than that of the lower air outlet, the wind speed of the upper air outlet is larger than that of the lower air outlet; when the effective area of the upper air outlet is larger than that of the lower air outlet, the wind speed of the upper air outlet is smaller than that of the lower air outlet, and the wind speeds and the air supply distances of the upper air outlet and the lower air outlet can be effectively adjusted by adjusting the upper door body assembly 310 and the lower door body assembly 320. Meanwhile, the upper door body 311 and the lower door body 321 are respectively provided with ventilation holes, so that the upper air outlet can realize no upper wind sense, and the lower air outlet can realize no lower wind sense. When the upper air outlet has no wind sense, the air speed and the air quantity of the lower air outlet are increased, and when the lower air outlet has no wind sense, the air speed and the air quantity of the upper air outlet are increased, so that the user is more comfortable under the condition of meeting the refrigeration requirement of the user and saving energy.
In order to improve the stability of door installation, the cabinet air conditioner comprises an upper driving assembly, a lower driving assembly 500 and a door bracket;
the upper driving component is arranged on the shell corresponding to the top of the air outlet, the door body support is arranged on the shell corresponding to the middle of the air outlet, and the lower driving component 500 is arranged on the shell corresponding to the bottom of the air outlet;
one end of the upper door body 311 is connected with the upper driving assembly, and the other end is arranged on the door body bracket; one end of the lower door 321 is connected to the lower driving assembly 500, and the other end is mounted on the door bracket.
Specifically, in this embodiment, the door body bracket is disposed in the middle of the air outlet, and is used to define the degree of freedom of the bottom of the upper door body 311 and the top of the upper door body 311. As for the effect of the door body bracket on the upper door body 311 and the lower door body 321, it may be set according to actual requirements. For the upper door 311, the door bracket may be used to support the upper door 311 and provide a moving track for the upper door 311, and of course, in some embodiments, only the upper door 311 may be provided with a moving track, where the upper door is suspended from the upper driving assembly. Similarly, the corresponding lower door 321 may be suspended on a door bracket, or may be supported by the lower driving assembly 500, where the door bracket provides a sliding track for the lower door 321. The track can be formed on the door body bracket or the door body, and can be arranged according to more practical requirements. In this embodiment, the door body bracket is exemplified as being formed on the door body bracket.
The form of the track is numerous and will be illustrated by way of example.
An upper chute and a lower chute are arranged on two opposite sides of the door body bracket, the lower part of the upper door body 311 is inserted into the upper chute, and the top of the lower door body 321 is inserted into the upper chute. In this embodiment, the lower portion of the upper door body 311 may be understood as the bottom of the upper door body 311, and may be understood as an installation portion provided at the lower portion of the upper door body 311. When the bottom of the upper door body 311 is directly inserted into the middle and upper sliding grooves, the installation is very simple. At this time, the door body bracket positioned in the middle of the air outlet is exposed to the outside. When the slider is provided at the back of the upper door body 311 and inserted into the upper chute, the gap between the bottom of the upper door body 311 and the top of the lower door body 321 can be set to be very small. Of course, the implementation of the above-described scheme requires that a slider is provided on the rear surface of the upper portion of the lower door 321, and the slider is inserted into the middle lower chute. So that there is no component separation between the top of the lower door 321 and the top of the upper door 311.
The cabinet air conditioner further comprises a connecting piece 700, and the connecting piece 700 is connected with the door body 300 without wind sense and the roller assembly 400; the rolling groove 120 is disposed on the housing 100 corresponding to the roller 420 of the roller assembly 400, and the roller 420 is disposed in the rolling groove 120. The driving assembly 500 includes: a driving motor fixedly connected with the housing 100; the driving gear 510 is fixedly connected with a rotating shaft of the driving motor; the driven rack 520 is meshed with the driving gear 510, and is detachably connected with the airless door 300.
In this embodiment, the driving motor is mounted on the housing 100 and detachably connected to the housing 100. There are many ways in which the driven rack 520 may be detachably connected to the airless door 300, such as by a snap-fit connection, a screw connection, a snap-fit connection, etc. When the driving motor works, the driving motor drives the gear 510 to rotate, the driving gear 510 drives the driven rack 520 to rotate, and the driven rack 520 drives the airless door 300 to move. In this driving process, since the entire weight of the non-wind-sensing door 300 is carried by the roller assembly 400, when the rack drives the non-wind-sensing door 300, the rack is only subjected to small resistance (only to overcome the static friction of the roller) of the non-wind-sensing door 300, that is, the load of the driving gear 510 and the driven rack 520 is small. Thereby being beneficial to prolonging the service lives of the driving gear 510 and the driven rack 520, improving the stability of the driving assembly 500 and improving the stability of the motion of the non-wind-sensing door body 300.
In order to improve the convenience of the connection between the airless door 300 and the driving assembly 500, a support column 521 is disposed on the side of the driven rack 520 facing away from the teeth; the cabinet air conditioner further comprises a connecting piece 700, and the connecting piece 700 is connected with the door body 300 without wind sense and the roller assembly 400; the connecting piece 700 is provided with a hanging lug 710 corresponding to the supporting column 521, the hanging lug 710 is provided with a slot 711, and the supporting column 521 is spliced with the hanging lug 710. In this embodiment, the support column 521 and the driven rack 520 are integrally formed, so that noise generated by friction between the support column 521 and the driven rack 520 is avoided when the door 300 without wind sensation is driven, and stability is improved.
