Detailed implementation manners

[0047] To make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope protected by the present utility model.

[0048] As Figure 5 and Figure 6 shown, the present utility model provides an air outlet and return air assembly, including an air outlet 1, an air return opening, a baffle 4, and an air return grille 5; wherein:

[0049] The air outlet 1 is arranged at the top of the refrigeration device; it should be noted here that the refrigeration device can be an air-cooled cabinet air conditioner, and of course it can also be other forms of refrigeration devices, as long as it is a refrigeration device with air outlet and return air requirements.

[0050] The number of return air outlets is at least two, which are respectively arranged on different sides of the refrigeration device; by arranging the return air outlets on different sides respectively, the return air can be carried out from different sides according to actual needs.

[0051] For the convenience of adjustment and interchange, all the return air outlets have the same specifications.

[0052] The return air grille 5 is detachably arranged on one of the return air outlets for return air filtration.

[0053] The baffle 4 is detachably arranged on the remaining return air outlets to close the return air outlets; specifically, when the return air grille 5 is installed on one of the return air outlets, that is, when the return air is carried out from this return air outlet, the other return air outlets need to be closed, then the baffle 4 is installed on the other return air outlets except the one where the return air is needed.

[0054] By adjusting the installation of the return air grille 5 on different return air outlets, the interchange adjustment of the return air direction can be carried out.

[0055] Since the return air outlets have the same specifications, the size of the return air grille 5 is the same as that of the baffle 4, that is, L3 = L4; when rear return air is needed, the baffle 4 can be removed from the rear return air outlet 3 and swapped with the front return air grille 5 in front to meet the interchange of the baffle 4 and the return air grille 5, which is convenient for switching on the engineering site.

[0056] The air outlet and return air assembly provided by the utility model can carry out the interchange adjustment of the return air direction. When the refrigeration device is placed indoors, the front return air can be directly carried out. When the refrigeration device is placed outdoors, through the interchange of the front return air, the rear return air or the left and right return air, the left and right or rear return air is introduced into the room through the pipeline, which is convenient for the disassembly and maintenance at the front panel.

[0057] The following takes the setting of two return air outlets as an example for specific description. The two return air outlets are respectively the front return air outlet 2 and the rear return air outlet 3. Among them, the front return air outlet 2 is arranged in the middle of the front side of the refrigeration device; the rear return air outlet 3 is arranged at the bottom of the rear side of the refrigeration device.

[0058] Of course, return air outlets can also be arranged on the left and right sides of the refrigeration device, which will not be elaborated here too much.

[0059] In order to facilitate the adjustment of the air outlet direction, in this embodiment, a guide air duct 6 capable of turning the air outlet direction is arranged on the air outlet 1, as Figure 8 shown. The guide air duct 6 can be introduced into the room to send the processed cold air to different areas of the room, making the indoor temperature field more uniform and the comfort better. Figure 8The middle air duct 6 can turn the air flow from the air outlet 1 by 90 degrees, then direct it to the rear side of the refrigeration equipment, and then send it to different areas of the room.

[0060] Of course, the air duct 6 can also adopt other angles, such as 45 degrees, 60 degrees, etc. The air duct 6 can also be directed to other directions such as the front side, left side, right side, etc., and is not limited to Figure 8 the backward direction in

[0061] The air supply and return air assembly of the present utility model can directly blow air out from the top, or can be installed with air ducts 6 in different air outlet directions to meet the blowing requirements in different directions of front, back, left, and right.

[0062] As another alternative embodiment of the present utility model, a jet air outlet or an air outlet with a sweeping function (not shown in the drawings) can also be provided on the air outlet 1.

[0063] By setting a jet air outlet or an air outlet with a sweeping function, real-time adjustment of the air outlet direction can be achieved.

[0064] The air-cooled cabinet is a DC motor with adjustable static pressure and rotational speed. It can adopt a high-speed and high-static-pressure mode to connect the air duct for long-distance air supply, sending cold air to different positions in the room. It can also adopt a low-speed and low-static-pressure mode to cooperate with air outlet accessories for direct air blowing. The air outlet accessories can be in various forms, such as jet air outlets, directional air outlets with louvers, or other directional air outlets, etc.

[0065] It should be noted that the return air outlet located on the front side of the refrigeration equipment is in the middle position, that is, the front return air outlet 2 is in the middle position on the front side of the refrigeration equipment; the return air outlet located on the rear side of the refrigeration equipment is in the bottom position, that is, the rear return air outlet 3 is in the bottom position on the rear side of the refrigeration equipment. The front return air outlet 2 and the rear return air outlet 3 are arranged in a staggered manner, and the rear return air outlet 3 is lower than the front return air outlet 2.

[0066] When there are more than two return air outlets, the return air outlets located on the left and right sides of the refrigeration equipment are in the bottom position.

[0067] That is, the left and right return air outlets are at the same height as the rear return air outlet 3, only on different sides.

[0068] The air supply and return air assembly of the present utility model can be applied to large air-cooled cabinet air conditioners (such as 20 horsepower). A 20-horsepower air conditioner has a large volume and takes up a large space indoors; when there is no space to install it indoors and it needs to be installed in the outdoor aisle, the front return air can be switched to the rear return air mode through the air supply and return air assembly. When the air-cooled cabinet is running, only one of the front return air and the rear return air can exist. The rear return air and the front return air of the air-cooled cabinet can be interchanged, and even extended to 4 optional return air directions of front, back, left, and right to meet different return air direction requirements.

[0069] As Figure 3 、 Figure 4 and Figure 5 shown, an air conditioner provided by the present utility model is an air-cooled cabinet air conditioner, which includes a cabinet body 10, a power-on / off operation component 20, and an air supply / return component, wherein:

[0070] The power-on / off operation component 20 is arranged on the front side of the cabinet body 10 and is electrically connected to an electrical box 30 located inside the cabinet body 10;

[0071] The air supply / return component is arranged on the cabinet body 10.

[0072] Specifically, when the number of return air openings is two, the front return air opening 2 is arranged in the middle of the front side of the cabinet body 10, below the power-on / off operation component 20; the rear return air opening 3 is arranged at the bottom of the rear side of the cabinet body 10, below the front return air opening 2. The air outlet 1 is located at the top of the cabinet body 10.

[0073] As an optional implementation manner of the present utility model, it further includes a fan system 40, an evaporator 80, a water receiving tray 50, and a filter screen assembly 60; wherein:

[0074] The fan system 40 is arranged inside the cabinet body 10 and is located below the air outlet 1, and is used to blow the air flow into the air outlet 1 through the inside of the cabinet body 10 and then blow it out through the air outlet 1;

[0075] The evaporator 80 is located below the fan system 40;

[0076] The filter screen assembly 60 is arranged close to the evaporator 80. Specifically, the filter screen assembly 60 is arranged in parallel with the evaporator 80 and is located below the evaporator 80;

[0077] The water receiving tray 50 is arranged below the filter screen assembly 60; considering that the water receiving tray 50 needs to receive the condensed water of the evaporator 80, the water receiving tray 50 needs to be arranged close to the evaporator 80, and the rear return air opening 3 is located at the bottom, so it will be located below the water receiving tray 50. In order to enable the air flow to pass through smoothly, there needs to be a gap between the water receiving tray 50 and the inner cavity of the cabinet body 10 for the air flow to pass through. Therefore, the length of the water receiving tray 50 must be less than the width of the cabinet body 10. In order to ensure the full reception of the condensed water, in this embodiment, the evaporator 80 is inclined; the filter screen 60 is parallel to the evaporator 80, so the filter screen 60 is also inclined, as Figure 4 shown.

[0078] Since the evaporator 80 is inclined, the condensed water on it will flow along the evaporator to the lower end, thus achieving the full reception of the condensed water.

[0079] The fan system 40 adopts a suction - type structural design. The fan system 40 directly sends the air processed by the evaporator 80 to the air outlet 1 at the top of the unit, facilitating multi - directional air supply (such as front, rear, left, and right) through the air duct at the top of the unit. (For example, Figure 8 is the rear air supply mode).

[0080] As a further improvement of the present utility model, as Figure 9 shown, an inclined guide rail 70 is provided on the side plate 90 of the evaporator 80. It should be noted here that the inclination here does not refer to the inclination of the extension direction of the guide rail 70, but rather means that the whole guide rail 70 has an inclination at a certain angle with the horizontal plane. The filter screen assembly 60 is movably arranged in the guide rail 70 in a pull - out manner. Specifically, as Figure 9 shown, the guide rail 70 is made of C - shaped channel steel.

[0081] The present utility model places the filter screen assembly 60 close to the evaporator 80, installs the filter screen assembly 60 through the guide rail 70 designed on the side plate 90 of the evaporator 80, and uses the guide rail 70 to pull out and push in the filter screen assembly 60, which is convenient for users to clean and replace the filter screen.

[0082] As a further improvement of the present utility model, the lower end of the filter screen assembly 60 is flush with the bottom of the front - side air return opening, and the upper end of the filter screen assembly 60 is flush with the top of the front - side air return opening. That is to say, the upper end of the filter screen assembly 60 is flush with the top of the front air return opening 2, and the lower end of the filter screen assembly 60 is flush with the bottom of the front air return opening 2.

[0083] The present utility model directly installs the filter screen assembly 60 in parallel with the evaporator 80, installs the filter screen assembly 60 by using the filter screen guide rail 70 structure at both plates of the evaporator 80, and uses the guide rail 70 for up - and - down push - pull installation. This is convenient for users to clean the filter screen and can also effectively avoid the collision noise problem between the grille panel and the filter screen caused by the vibration of the grille panel when the filter screen is installed on the front air return grille 5.

[0084] As a further improvement of the present utility model, as Figure 3 and Figure 4 shown, the length L2 of the water receiving tray 50 is less than the width L1 of the cabinet 10, and the rear end of the water receiving tray 50 is connected to the rear side of the cabinet 10. There is an air - passing interval between the front end of the water receiving tray 50 and the front side of the cabinet, and this interval is equal to L2 - L1. It is recommended that this interval be greater than 10 mm, and values such as 100 mm and 200 mm can be taken.

[0085] As a further improvement of the present utility model, as Figure 4 shown, the rear end of the water receiving tray 50 is fitted and arranged at the lower - end position of the filter screen assembly 60.

[0086] It should be noted here that the water receiving tray 50 should be at a certain distance from the bottom of the unit, that is, L4>0, so as to realize the rear return air from the lower part of the water receiving tray 50, and then the rear return air flows into the evaporator 80 through the gap between the water receiving tray 50 and the front for heat exchange.

[0087] Usage method: As Figure 5 shown, when the air conditioner adopts front return air, the air conditioner can be directly placed in the room, and the return air outlet does not need to be connected to the air duct. The air outlet 1 can blow directly or can be equipped with air outlets with different air outlet directions (such as jet air outlets, etc.) on the top of the unit to realize that the unit can meet the blowing requirements in different directions such as front, back, left, and right (such as Figure 8 is the rear return air scheme)

[0088] When the air conditioner adopts rear return air, the air-cooled cabinet air conditioner can be placed in the aisle outside the room and connected to the indoor through the return air duct and the guide air duct, such as Figure 7 and Figure 8 shown, which can save the air conditioner installation area in the room. In this way, the on-off control part of the air conditioner is on the front of the air conditioner, and the unit can be controlled or disassembled and repaired in the aisle outside the room. The wired controller connected to the unit control can also be installed on the indoor side, and the user can set the air conditioner through the wired controller in the room, such as Figure 8 shown.

[0089] Here, it should be noted first that "inward" is the direction towards the center of the accommodating space, and "outward" is the direction away from the center of the accommodating space.
