The inner side of the shell air inlet 115 is provided with a connecting bracket 116, and the heat exchanger 160 is arranged between the shell air inlet 115 and the upper air duct assembly 120 and is connected with the connecting bracket 116; the electric auxiliary heating device 170 is disposed between the heat exchanger 160 and the axis of the rotation shaft of the lower fan 132.

Specifically, the case 110 includes a base 113, a cover 111, and a front panel 112 and a rear panel 114 connected to each other; the front panel 112 and the rear panel 114 are connected to form a cylindrical structure, the base 113 is disposed at the lower end of the cylindrical structure, and the cover 111 is disposed at the upper end of the cylindrical structure.

Referring to fig. 1 and 2, the upper duct assembly 120 includes a mounting housing 122 and two upper fans 121, wherein the two upper fans 121 are disposed in the mounting housing 122, and one of the fans is located above the other fan. The two upper fans 121 are centrifugal fans, and air inlets on the side surfaces of the two upper fans are vertically arranged and are opposite to the shell air inlet 115 on the rear panel 114 at intervals; so that the wind coming from the housing wind inlet 115 can directly enter the upper fan 121.

Referring to fig. 1, an air outlet assembly 140 is further disposed on the upper portion of the upper duct assembly 120, the air outlet assembly 140 includes an air outlet channel 142, and the upper duct assembly 120 is communicated with an upper air outlet 1121 of the housing 110 through the air outlet assembly 140. The wind coming out of the upper duct assembly 120 is blown into the room through the wind outlet channel 142 and the upper wind outlet 1121.

Referring to fig. 1 and 3, the heat exchanger 160 is vertically disposed between the housing inlet 115 and the upper duct assembly 120, and is mounted adjacent to the housing inlet 115. The air from the housing inlet 115 is heat exchanged by the heat exchanger 160 and then directly enters the upper duct assembly 120. Since the heat exchanger 160 can be purchased directly, a detailed description of the specific structure of the heat exchanger 160 is omitted to avoid redundancy.

The lower duct assembly 130 is disposed at a lower portion of the case 110 and below the heat exchanger 160; which includes a lower fan 132.

An air guide channel 150 is further disposed at the air outlet of the lower fan 132, and the lower fan 132 is communicated with the lower air outlet 1122 of the housing 110 through the air guide channel 150. Along the air outlet direction, the air guide channel 150 is arranged obliquely downwards; so that the wind direction of the wind coming out of the lower fan 132 changes from horizontal to downward inclined after passing through the wind guide passage 150. The above design allows the air coming out of the lower outlet 1122 to be directly blown onto the ground, thereby facilitating carpet heating.

Referring to fig. 4, since the rotation axis of the impeller of the lower fan 132 is vertically arranged, a vertical axis can be defined along the rotation axis.

With continuing reference to fig. 1 and with reference to fig. 13 and 14, in order to facilitate installation of the electric auxiliary heating device 170 and to prevent the condensed water on the heat exchanger 160 from falling into the lower duct assembly 130; the cabinet air conditioner in this embodiment is further provided with a water pan 180. The drip tray 180 is disposed under the heat exchanger 160 and connected to the lower fan 132.

Specifically, the drip tray 180 includes an annular body 182 and a bar-shaped mounting bar 184. The lower part of the annular body 182 is connected with the air inlet of the lower fan 132, the middle part of the annular body is provided with a vent 1822 with the diameter approximately equal to that of the air inlet of the lower fan 132, and the vent 1822 is communicated with the air inlet of the lower fan 132. The annular body 182 is provided with a water receiving groove 1821 at the upper part, and the water receiving groove 1821 extends along the annular body 182. The heat exchanger 160 is substantially U-shaped in cross section, and condensate water formed on the heat exchanger 160 and the air passage surface opposite to the heat exchanger 160 can directly fall into the lower water receiving tank 1821. A flow guide pipe 190 is disposed at a lower portion of the water receiving tank 1821, and the condensed water flows to the outside of the housing 110 through the flow guide pipe 190.

The mounting bar 184 spans the vent holes 1822 in the annular body 182 with both ends connected to the annular body 182. The middle of the mounting rod 184 is provided with a horizontal fixing plate 1841, the fixing plate 1841 is provided with a threaded hole, and the bottom of the electric auxiliary heating device 170 is fixedly connected with the fixing plate 1841 through a screw. The mounting rod 184 is provided with a strip-shaped diversion trench 1842, and the diversion trench 1842 extends along the length direction of the mounting rod 184 and is communicated with a water receiving trench 1821 on the annular body 182. The condensed water formed from the electric auxiliary heating device 170 can directly flow into the guide slots 1842 of the mounting bar 184 and flow into the water receiving slots 1821 through the guide slots 1842.

The water pan 180 with the structure enables the electric auxiliary heating device 170 to be vertically suspended above the lower fan 132, so that the electric auxiliary heating device 170 has small influence on the air inlet of the lower air duct assembly 130; and the drain pan 180 can guide the condensed water to the outside of the case 110, preventing the condensed water from being blown into the room by the lower fan 132.

The use method and the beneficial effects of the cabinet air conditioner provided by the embodiment are as follows:

when the cabinet air conditioner is heating (fig. 15), hot air is blown out from the upper air outlet 1121 and the lower air outlet 1122; the hot air coming out of the lower air outlet 1122 can fall to the ground in time, so that carpet heating is realized. And, since the hot wind itself is light, it can be automatically raised. Therefore, the air from the upper outlet 1121 and the lower outlet 1122 can quickly heat the upper space and the lower space in the room; and the temperature of the upper and lower indoor spaces is relatively uniform. During cooling (fig. 16), the lower fan 132 does not operate, and air can be simultaneously fed from the housing air inlet 115 and the lower air outlet 1122, so that the air inlet amount of the upper fan 121 is increased. Cold air is blown out from the upper air outlet 1121 of the housing 110, and can automatically sink due to the fact that the cold air is heavy; in the sinking process, the user experiences bath type refrigeration, and rapid and uniform refrigeration of the upper space and the lower space can be realized.
