As shown in fig. 1, each coil 41 is shaped as a fold line, and the gathered ends and the spread ends of the plurality of coils 41 are not in the same plane. It should be noted that, although the inlet ends of the plurality of coils 41 in the preferred embodiment are finally gathered to the same point, the inlet ends of the plurality of coils 41 may obviously be disposed in a dispersed manner, as long as the outlet ends of the plurality of coils 41 are disposed in a dispersed manner with respect to the inlet ends thereof, that is, as long as the overall shape of the heat exchanger 4 approximates a trumpet shape. Meanwhile, the present invention does not limit the specific shape and number of the fins 42, as long as the fins 42 can be connected to the coil 41 so as to facilitate heat dissipation of the coil 41. In addition, it should be noted that the specific shape of the coil 41 is not limited in the present invention, that is, a technician can set the bending angle of the coil 41 according to the actual requirement, and the shapes of different coils 41 can be the same or different, so long as each coil 41 is in a zigzag shape.

Referring next to fig. 1, as a preferred embodiment, each coil 41 includes a plurality of horizontal sections 411 and vertical sections 412 connected to each other, so that each coil 41 presents a stepped shape, and when the heat exchanger 4 is installed in place, the horizontal sections 411 are disposed horizontally, and the vertical sections 412 are disposed vertically, with the arrow direction in the figure being the flow direction of the refrigerant. It should be noted that this arrangement is obviously not limiting, and the skilled person can set the specific shape of each coil 41 and the overall shape of all coils 41 after being installed in place according to the actual use requirement. In addition, it can be understood that, since the fins 42 are disposed perpendicular to the length direction of the coil 41, the coil 41 is configured to be composed of a plurality of horizontal sections 411 and vertical sections 412, so that air can be in contact with the coil 41 or the fins 42 in front, and the heat exchange effect of the heat exchanger 4 is effectively ensured. Preferably, the fins 42 comprise a plurality of annular fins of different radial dimensions, each of which is provided with the same number of through holes as the coils 41, and which can be directly sleeved onto all the coils 41 through these through holes so that each annular fin is in contact with all the coils 41; at the same time, the dimensions of the annular fins and the position of the through holes determine the space position of each coil 41 after installation, and each annular fin is perpendicular to the length direction of the coil when the heat exchanger 4 is assembled in place. It will be appreciated by those skilled in the art that the present invention is not limited in any way to the specific shape and mounting of the fins 42, and that the skilled person can set it up according to the actual use requirements.

Further, in the preferred embodiment, the inlet ends of the coils 41 are further provided with a liquid separating member 43, a spherical cavity is formed in the liquid separating member 43, and the liquid separating member 43 is provided with a liquid inlet hole and a plurality of liquid outlet holes, and the liquid inlet holes and the liquid outlet holes are communicated with the spherical cavity; the number of the liquid outlet holes is equal to that of the coils 41, the liquid distribution member 43 is communicated with the main pipeline of the cabinet air conditioner through the liquid inlet holes, so that the refrigerant in the main pipeline can flow into the liquid distribution member 43 through the liquid inlet holes, and each liquid outlet hole of the liquid distribution member 43 is respectively connected with the inlet end of one coil 41, so that the refrigerant in the main pipeline can uniformly flow into each coil 41 after being distributed by the liquid distribution member 43. It should be noted that, the specific structure of the liquid separating member 43 is not limited in the present invention, as long as the liquid separating member 43 can perform a flow separating function; meanwhile, the invention can also be used for directly connecting each coil 41 with different refrigerant pipelines without arranging the liquid separating component 43.

In addition, it can be understood that the liquid separating member 43 of the present invention effectively ensures that the liquid separating member 43 can uniformly separate by providing the spherical cavity, and because the spherical cavity is centrosymmetric, the stress conditions of each point in the spherical cavity are also symmetrically distributed, thereby facilitating the liquid separating member 43 to uniformly separate liquid. After the refrigerant enters the spherical cavity through the liquid inlet holes of the liquid separating member 43, the refrigerant is not influenced by concentrated stress in the spherical cavity because the spherical cavity is smooth, so that the pressure at each liquid outlet hole of the liquid separating member 43 is uniform, namely the stress conditions at each liquid outlet hole are similar, so that the refrigerant in the spherical cavity can uniformly flow into each coil 41 through a plurality of liquid outlet holes of the liquid separating member 43, and the liquid separating member 43 can be effectively ensured to uniformly split so as to effectively ensure the heat exchange efficiency of the cabinet air conditioner.

With continued reference to fig. 1 and 2, as a preferred embodiment, the heat exchanger 4 of the present invention further includes a circular outlet line 44, with all of the outlet ends of the coils 41 being connected to the outlet line 44. Specifically, the output pipeline 44 is provided with through holes the same as the coils 41 in number, and each coil 41 is correspondingly connected with one through hole, so that the refrigerant in all coils 41 can flow out through the output pipeline 44, and the heat loss of the refrigerant in the transmission process is further reduced. It should be noted that, the specific shape of the output pipe 44 is not limited in the present invention, and the output pipe 44 may be circular, square, or other shapes; meanwhile, the heat exchanger 4 may not even be provided with the output pipeline 44, i.e. all coils 41 are directly connected to the main pipeline of the cabinet air conditioner. Further, the through holes on the output pipeline 44 are uniformly arranged along the circumferential direction, that is, the outlet ends of the plurality of coils 41 of the heat exchanger 4 are uniformly connected to the output pipeline 44 along the circumferential direction, so that the same distance between two adjacent coils 41 can be kept, and the same heat exchanging space of each coil 41 can be effectively ensured. In addition, it will be appreciated by those skilled in the art that this connection is not limiting, and that the skilled person may set the specific connection between each coil 41 and the output line 44 according to the actual requirements.

According to the invention, the heat exchanger 4 in the preferred embodiment is arranged in the machine body 1 of the indoor unit of the cabinet air conditioner, so that the cabinet air conditioner can exchange heat more uniformly during operation, the heat exchange effect is better, and the problem of poor heat exchange effect of the conventional heat exchanger is effectively avoided. Meanwhile, the humidifying device 2 is arranged at the first air outlet 123, so that the water vapor discharged by the humidifying device 2 can be uniformly mixed with the air subjected to heat exchange by the air supply effect of the first air outlet 123 and sent to all corners of a room. Although the cabinet air-conditioning indoor unit 1 according to the preferred embodiment is provided with the sterilization and purification module 7, the cabinet air-conditioning indoor unit according to the present invention is not limited thereto, and the cabinet air-conditioning indoor unit according to the present invention may not include the sterilization and purification module 7, that is, may be provided with the air inlet 111 directly below the water pan 5.

Preferably, the air supply fan 3 adopts a digital turbine motor (or digital motor), and the motor has the characteristics of high rotating speed, capability of generating strong suction force and the like, and the highest rotating speed is close to 11 ten thousand revolutions per minute and is 4-5 times of the rotating speed of the motor of the common fan. According to the invention, the machine body 1 is rotatably connected with the base 6, so that the air conditioner can freely rotate during installation, an optimal installation angle is conveniently found, the installation difficulty is reduced, and the applicability of the air conditioner is improved. Meanwhile, a gap is formed between the machine body 1 and the base 6, and the air inlet 111 is arranged at the bottom of the machine body 1, so that the area of the air inlet 111 is larger, the air inlet quantity is larger, and the large-scale circulation of indoor air and the improvement of heat exchange effect and heat exchange efficiency are facilitated. Meanwhile, a guide inclined plane is further arranged on the base 6 so that air inlet can be guided initially, and therefore smoothness of the air inlet is improved effectively.

A specific embodiment of the annular air-out structure will be described with reference to fig. 3, 4 and 5, wherein fig. 4 is a cross-sectional view of a first air-out mode of the annular air-out structure according to the present invention; fig. 5 is a cross-sectional view of a second air-out mode of the annular air-out structure of the present invention. As shown in fig. 3-5, the annular air outlet structure 12 includes an inner annular surface 121 and an outer annular surface 122, the outer annular surface 122 is sleeved on the outer side of the inner annular surface 121, and forms an air outlet cavity with the inner annular surface 121, a first air outlet 123 is formed between the front end of the outer annular surface 122 and the front end of the inner annular surface 121, a second air outlet 124 is formed on the side surface of the outer annular surface 122, and the rear end of the outer annular surface 122 is in closed connection with the rear end of the inner annular surface 121. The first air outlet 123 is provided with a first blocking piece mechanism 125, and the first blocking piece mechanism 125 can selectively open or close the first air outlet 123. Similarly, a second flap mechanism 126 is disposed at the second air outlet 124, and the second flap mechanism 126 can selectively open or close the second air outlet 124. Meanwhile, the bottom end of the outer ring surface 122 is further provided with a vent hole, and after the annular air outlet structure 12 is fixedly connected to the columnar shell 11, the air outlet cavity is communicated with the columnar shell 11 through the vent hole. In addition, the humidifying device 2 includes a water tank 21 and an atomizer 22, such as an ultrasonic atomizer or an air compression atomizer, disposed in the water tank 21, wherein the water tank 21 is fixedly connected to the bottom of the inner annular surface 121, and the atomizer 22 is capable of atomizing the liquid in the water tank 21 into water mist.

It will be understood by those skilled in the art that, although the specific structures of the first flap mechanism 125 and the second flap mechanism 126 are not specifically shown in the drawings of the present embodiment, the implementation forms of the first flap mechanism 125 and the second flap mechanism 126 are obviously various, as long as the arrangement manner can effectively realize the opening and closing control of the first air outlet 123 and the second air outlet 124. For example, the first baffle mechanism 125 and/or the second baffle mechanism 126 may be implemented in the form of a linear motor controlled annular retainer ring, and the linear motor drives the annular retainer ring to move back and forth in the air outlet cavity to implement opening and closing control of the first air outlet 123 and/or the second air outlet 124; or the linear motor can be replaced by a combination of a rotary motor, a gear rack, a chain and the like. For another example, the first baffle mechanism 125 and/or the second baffle mechanism 126 may also implement opening and closing control of the first air outlet 123 and/or the second air outlet 124 by electromagnetic adsorption, that is, the retainer ring is made of a metal material, an electromagnetic coil is disposed in the air outlet cavity, an elastic member is disposed between the retainer ring and the inner ring surface 121 or the outer ring surface 122, and when the power is on, the electromagnetic coil generates magnetic force to attract the retainer ring, and the elastic member stores elastic potential energy, so as to open the first air outlet 123 and/or the second air outlet 124; when the electromagnetic coil is powered off, the retainer ring returns to the initial position under the action of the elastic member, so that the first air outlet 123 and/or the second air outlet 124 are/is closed. For another example, one of the first shutter mechanism 125 and the second shutter mechanism 126 may be omitted, and the selective opening of either the first air outlet 123 or the second air outlet 124 may be achieved by controlling the movement of the one shutter mechanism.

Further, the inner annular surface 121 and/or the outer annular surface 122 are/is further provided with an air guiding structure, which is configured to gradually reduce the air outlet width at the air outlet. The two arc plates are adopted as shown in fig. 3 or 4, and the two arc plates are arranged to gradually narrow the outlet width of the first air outlet 123 and the second air outlet 124, so that a venturi effect can be generated to accelerate the flow speed when the air flow passes through the air outlet, and the spraying effect is realized. And when the air is sprayed, negative pressure is generated near the annular air outlet, and the negative pressure can attract air near the annular air outlet to flow together, so that the circulation of indoor air is realized, and the air supply quantity of the indoor unit of the cabinet air conditioner is effectively improved. Of course, the air guiding structure may be any other arrangement manner, so long as the arrangement manner can enable the air outlet width of the first air outlet 123 and/or the second air outlet 124 to be gradually narrowed. It can be understood that the annular air outlet structure 12 is arranged at the top of the columnar shell 11, the first air outlet 123 and the second air outlet 124 are arranged on the annular air outlet structure 12, and a baffle mechanism is respectively arranged at the first air outlet 123 and the second air outlet 124, so that the cabinet air conditioner indoor unit has a brand new air outlet structure and two air outlet modes, namely, a spraying mode and a diffusion mode, and a user can flexibly select the air outlet mode based on needs.
