[0026] Compared with the prior art, the main advantages of this utility model are:
[0027] (1) Significantly improves the overall appearance and aesthetics; the rear, left or right side walls of the casing usually no longer need to have air inlets, so they can be designed to be simpler, flatter and more integrated, eliminating the problem of air inlets ruining the overall aesthetics in traditional designs, and meeting the aesthetic needs of modern homes for concealed and simple product appearance; it realizes the "concealment" of the air inlet of the cabinet air conditioner, and solves the problem of the air inlet being exposed in the existing cabinet air conditioner, which affects the overall aesthetics;
[0028] (2) Optimize airflow path and heat exchange efficiency; the chassis is located at a low position and is usually close to the ground; cold air has a higher density and is more likely to settle and accumulate in the lower part of the room; the chassis air intake design makes it easier to draw in low-temperature air from the lower part of the room; the drawn-in low-temperature air enters the main air duct through the internal lower air intake duct. This bottom-up airflow path is more in line with the natural convection characteristics of cold and hot air, which helps to improve heat exchange efficiency and cooling / heating speed.
[0029] (3) The air inlet cavity is located at the bottom of the casing. Air needs to pass through the internal lower air inlet duct to reach the air duct where the fan is located. This structure has a certain shielding and attenuation effect on the noise generated by the air inlet (such as vortex sound and fan suction sound), which helps to reduce the overall noise level of the machine that users can perceive.

[0045] In existing cabinet air conditioners, the air inlet is located on the rear, left, or right side wall of the casing. The air inlet is directly exposed on the visible part of the outer surface of the casing, which damages the integrity and simplicity of the casing's appearance and affects the overall aesthetic effect of the air conditioner cabinet.
[0046] This utility model creatively provides a cabinet-type air conditioner, including a casing and a chassis. The casing wall forms an air outlet, and the interior of the casing forms a main air duct with a main air duct inlet and a main air duct outlet. The chassis is located at the bottom of the casing, and an air inlet cavity is formed between the chassis and the casing. The air inlet cavity and the main air duct inlet are connected through a lower air inlet duct, and the main air duct outlet and the air outlet are connected.
[0047] Indoor air can flow sequentially through the air inlet cavity and the lower air inlet duct, enter the main air duct through the main air duct inlet, and then be discharged through the main air duct outlet;
[0048] An air intake cavity is formed between the chassis and the casing, which realizes the "concealment" of the air intake of the cabinet air conditioner, maximizes the integrity and aesthetics of the casing, and solves the problem of the air intake being exposed in existing cabinet air conditioners, which affects the overall appearance.
[0049] Example 1
[0050] like Figures 1 to 3 As shown, this embodiment provides a cabinet-type air conditioner, including an indoor unit, which includes:
[0051] The casing 1 has an air outlet formed on its wall; the interior of the casing 1 is provided with a main air duct 13, which has a main air duct inlet and a main air duct outlet.
[0052] The chassis 21 is located at the bottom of the housing 1; an air inlet cavity 215 is formed between the chassis 21 and the housing 1, or the chassis 21 forms an air inlet cavity 215.
[0053] Inside the casing 1, a lower air inlet duct 16 is formed between the air inlet cavity 215 and the main air duct inlet. The lower air inlet duct 16 connects the air inlet cavity 215 and the main air duct inlet. The main air duct outlet and the air outlet are connected. Both the air inlet cavity 215 and the air outlet are connected to the room.
[0054] Indoor air enters the lower air inlet duct 16 through the air inlet cavity 215, and then enters the main air duct 13 through the main air duct inlet. The air in the main air duct 13 is discharged into the room through the main air duct outlet and the air outlet. The air inlet cavity 215 is located between the chassis 21 and the casing 1, which is well concealed and makes the overall appearance of the cabinet air conditioner better. It is not easy for dust to accumulate, which reduces the maintenance difficulty of the cabinet air conditioner.
[0055] Specifically, the cabinet air conditioner also includes an indoor heat exchanger 4, which is located inside the casing 1 and on the air inlet side of the main air duct inlet (preferably, the indoor heat exchanger 4 is located in the flow path between the upper air outlet and the upper air supply duct); the air in the lower air inlet duct 16 flows through the indoor heat exchanger 4 and exchanges heat with the indoor heat exchanger 4, and then enters the main air duct 13 through the main air duct inlet.
[0056] The specific location and structure of the air inlet 215 are described below. The air inlet 215 is formed inside the chassis 21. The air inlet 215 opens at the side wall of the chassis 21 to form a side air inlet 213. The air inlet 215 opens at the top wall of the chassis 21 to form a top air inlet 214. The top air inlet 214 and the main air duct inlet are connected through the lower air inlet 16.
[0057] Indoor air enters the air intake chamber 215 through the side air inlet 213, and then enters the lower air intake duct 16 through the top air inlet 214.
[0058] Preferably, air inlet chambers 215 are formed inside the chassis 21 and near the front side wall 211 and the rear side wall 212 of the chassis 21. That is, a part of the indoor air flows sequentially through the air inlet chamber 215 near the front side wall 211 of the chassis 21 and the lower air inlet duct 16 into the main air duct 13, and another part of the indoor air flows sequentially through the air inlet chamber 215 near the rear side wall 212 of the chassis 21 and the lower air inlet duct 16 into the main air duct 13.
[0059] like Figure 4a and Figure 4b As shown below, the structure required to adjust the opening size of the top air inlet 214 is described. The top air inlet 214 is provided with a movable wind-blocking structure 22. The wind-blocking structure 22 can be controlled to open or close the top air inlet 214, or adjust the opening size of the top air inlet 214 when the top air inlet 214 is in the open state.
[0060] When the cabinet air conditioner stops running, the top air inlet 214 is closed by the wind deflector 22 to prevent indoor dust from entering the lower air inlet 16 with the air.
[0061] The opening size of the top air inlet 214 is positively correlated with the air intake volume. The opening size of the top air inlet 214 can be controlled by the wind baffle structure 22, thereby precisely controlling the air intake volume of the cabinet air conditioner, meeting different air outlet requirements, and improving the operating efficiency of the cabinet air conditioner.
[0062] Furthermore, the windproof structure 22 is a baffle, which is installed at the top air inlet 214 in a way that can be flipped up and down; the baffle and the baffle motor (i.e. the windproof motor 23) are driven and connected; when the baffle motor is running, the baffle flips up and down, thereby opening or closing, or adjusting the opening size of the top air inlet 214 when it is in the open state.
[0063] Specifically, the baffle motor is fixed to the top wall of the chassis 21 by screws, the baffle extends in the left and right direction of the housing 1, one end of the baffle in the left and right direction of the housing 1 is rotatably mounted on the chassis 21 or the housing wall of the housing 1 by a rotating shaft, and the other end is driven and connected to the output shaft of the baffle motor by another rotating shaft.
[0064] The following describes the structure required for filtering the air intake. A grille 24 is provided at the top air intake 214. The grille 24 includes an integrally formed grille body and a grille filter. The grille body can support the grille filter, which can effectively filter impurities in the indoor air and prevent impurities from entering the lower air intake duct 16 with the indoor air, thus avoiding the problems of grille filter deformation and easy detachment. It is easy to disassemble and assemble, and convenient to clean the grille filter.
[0065] Specifically, the top of the grille 24 is flush with the top wall of the chassis 21, which solves the problem of exposed air inlets and easy dust accumulation in existing cabinet air conditioners; the grille 24 is fixed to the chassis 21 or the shell wall of the housing 1 by clips or screws, which facilitates disassembly and assembly.
[0066] The following describes the specific structure of the main air duct 13, which includes an upper air outlet 151 and a lower air outlet 171 arranged opposite each other.
[0067] The casing 1 comprises a front casing wall 11, a rear casing wall 12, a left casing wall, a right casing wall 17, and a top casing wall 15. The front casing wall 11 and the rear casing wall 12 are arranged opposite each other front to back, and the left casing wall and the right casing wall 17 are arranged opposite each other left to right. The front casing wall 11, the left casing wall, the rear casing wall 12, and the right casing wall 17 are connected sequentially and form a circumference. The top casing wall 15 is located at the top of the casing 1 and is connected to both the left casing wall and the right casing wall 17. The top casing wall 15 has an upper outlet. Air vent 151, a lower air outlet 171 is formed at the lower end of the left shell wall and / or the lower end of the right shell wall 17; both the upper air outlet 151 and the lower air outlet 171 are provided with air outlet grilles; air inlet chambers 215 are formed between the lower edge of the front shell wall 11 and the front side wall 211 of the chassis 21 and between the lower edge of the rear shell wall 12 and the rear side wall 212 of the chassis 21; specifically, the front shell wall 11 and the rear shell wall 12 are mounted on the chassis 21 by screws or pins;
[0068] The main air duct 13 includes an upper air supply duct 131, a blade cavity 133, and a lower air supply duct 132 arranged sequentially from top to bottom. The blade cavity 133 has a blade cavity inlet 1331, a blade cavity upper outlet 1332, and a blade cavity lower outlet 1333, all of which are connected to the blade cavity 133. The blade cavity upper outlet 1332 and the upper air outlet 151 are connected through the upper air supply duct 131, and the blade cavity lower outlet 1333 and the lower air outlet 171 are connected through the lower air supply duct 132. That is, the upper air outlet 151, the upper air supply duct 131, the upper outlet 1332, and the blade cavity 133 are connected sequentially, and the blade cavity 133, the blade cavity lower outlet 1333, the lower air supply duct 132, and the lower air outlet 171 are connected sequentially.
[0069] A lower air inlet duct 16 is formed between the housing 1, the fan blade cavity 133, and the lower air supply duct 132;
[0070] The fan blade cavity 133 is equipped with a rotatable fan blade 14, which is connected to a fan blade motor. When the fan blade motor drives the fan blade 14 to rotate, indoor air enters the lower air inlet duct 16 through the air inlet cavity 215. The air in the lower air inlet duct 16 flows through the indoor heat exchanger 4 and exchanges heat with it before entering the fan blade cavity 133 through the fan blade cavity inlet 1331. A portion of the air in the fan blade cavity 133 flows sequentially through the upper outlet 1332, the upper air supply duct 131, and the upper air outlet 151, and is discharged into the room. Another portion of the air in the fan blade cavity 133 flows sequentially through the lower outlet 1333, the lower air supply duct 132, and the lower air outlet 171, and is discharged into the room. In this way, air can be discharged from both the upper and lower parts of the room.
[0071] Among them, the inlet of the fan blade cavity 1331 is the main air duct inlet, and the air outlet of the upper air duct 131 and the air outlet of the lower air duct 132 both form the main air duct outlet.
[0072] Preferably, the fan blade 14 is a centrifugal fan blade; the axis of the fan blade cavity 133 extends in the horizontal direction, and one or both ends of the fan blade cavity 133 form a fan blade cavity inlet 1331; the upper end of the fan blade cavity 133 forms a fan blade cavity upper outlet 1332, and the lower end of the fan blade cavity 133 forms a fan blade cavity lower outlet 1333.
[0073] The following describes the control method for the opening size of the top air inlet 214. The cabinet air conditioner also includes a baffle motor 23 and a controller. The baffle motor 23 and the baffle structure 22 are connected by a drive, and the controller and the baffle motor 23 are connected by communication.
[0074] The controller is configured to control the operation of the baffle motor 23 according to the target air intake volume of the cabinet air conditioner, so that the opening size of the top air inlet 214 is adapted to the target air intake volume.
[0075] Furthermore, the cabinet air conditioner has multiple air intake modes, and different air intake modes have different air intake volumes;
[0076] The wind deflector structure 22 has multiple gears, and each gear corresponds to a different air intake mode. When the wind deflector structure 22 is in different gears, the opening size of the top air intake 214 is different.
[0077] The controller is configured to control the operation of the baffle motor 23 according to the air intake mode of the cabinet air conditioner, so that the baffle structure 22 is adapted to the air intake mode.
[0078] Specifically, the methods for controlling the air intake volume of the top air inlet 214 through the windbreak structure 22 include:
[0079] The first step is for users to directly turn on or schedule a specific time to turn on the cabinet air conditioner;
[0080] The second step is for the user to select the air intake mode. There are multiple air intake modes, including high air volume air intake mode, medium air volume air intake mode and low air volume air intake mode.
[0081] The third step is to determine the air intake mode selected by the user and control the operation of the wind deflector motor 23 according to the air intake mode selected by the user, so that the deflector structure 22 is matched with the air intake mode selected by the user.
[0082] If the user selects the high-volume air intake mode, the controller controls the baffle motor to rotate the baffle to angle A. In this embodiment, angle A is 90°, which is perpendicular to the ground, so that the top air intake 214 is fully open. The indoor unit takes in air completely from the top air intake 214 to meet the user's high-volume air intake needs.
[0083] If the user selects the medium air intake mode, the controller controls the baffle motor to rotate the baffle to angle B. In this embodiment, angle B is 60°, which is 60° with the ground, so that the top air intake 214 is in a partially open state; the indoor unit takes in air from the top air intake 214 to meet the user's medium air intake needs.
[0084] If the user selects the low airflow mode, the controller controls the baffle motor to rotate the baffle to angle C. In this embodiment, angle C is 45°, which is 45° to the ground. Alternatively, the top air inlet 214 on one side of the chassis 21 is completely closed while the top air inlet 214 on the other side of the chassis 21 is partially open. The indoor unit draws air from the top air inlet 214 to meet the user's low airflow needs.
[0085] Fourth step, the user can directly turn off or schedule to turn off the air conditioner at a specific time. At this time, the fan motor stops running, the controller controls the baffle motor to run, and the baffle rotates to be parallel to the ground; at this time, the baffle completely covers the top air inlet 214, so that the top air inlet 214 is in a completely closed state.
[0086] In addition, the cabinet air conditioner also includes a fresh air module 3, which is located at the lower end of the interior of the casing 1. The fresh air module 3 is used to deliver outdoor fresh air to the room.
[0087] An air inlet cavity 215 is formed between the lower end of the chassis 21 and the casing 1, which is well concealed and maximizes the integrity, aesthetics and appearance consistency of the cabinet air conditioner. The indoor unit can be wall-mounted, which solves the problem that the air inlet of the existing cabinet air conditioner is set on the casing 1 and the indoor unit needs to maintain a distance from the wall. It avoids the problems of air volume loss, curtain absorption or noise radiation caused by the indoor unit being set against the wall when the casing 1 has an air inlet, and reduces the restrictions on the installation environment.
[0088] Example 2
[0089] Unlike Embodiment 1, the side wall of the chassis 21 is recessed towards the inside of the chassis 21 to form an air intake cavity 215;
[0090] A side air inlet 213 is formed between the side wall of the chassis 21 forming the air inlet cavity 215 and the lower edge of the housing 1. A top air inlet 214 is formed between the top wall of the chassis 21 at the location corresponding to the air inlet cavity 215 and the lower edge of the housing 1.
[0091] Preferably, the front sidewall 211 and the rear sidewall 212 of the chassis 21 are recessed inward to form an air inlet cavity 215; that is, a part of the indoor air flows sequentially through the air inlet cavity 215 of the front sidewall 211 of the chassis 21 and the lower air inlet duct 16 into the main air duct 13, and another part of the indoor air flows sequentially through the air inlet cavity 215 of the rear sidewall 212 of the chassis 21 and the lower air inlet duct 16 into the main air duct 13.
[0092] Example 3
[0093] Based on Embodiment 1, this embodiment proposes that the shell wall of the housing 1 is also formed with an upper air inlet, and an upper air inlet duct is formed inside the housing 1 between the upper air inlet and the air duct inlet; a portion of the indoor air can flow sequentially through the upper air inlet, the upper air inlet duct and the air duct inlet into the air duct.
[0094] The upper air inlet serves as the main air inlet, while the lower air inlet serves as the auxiliary air inlet, thereby increasing the air volume.
