DETAILED DESCRIPTION

It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

In one embodiment of the present invention, an air conditioning unit is provided that blows cool air without being cold and has constant temperature dehumidification. By combining an air conditioner with an air conditioning fan, the air conditioning fan and the air conditioner blow air at the same time. The upper part of the indoor unit of the air conditioning unit adopts an evaporator, which is connected to a compressor. Refrigerant flows inside the evaporator, and blows cold air through heat exchange to quickly reduce the indoor temperature; the lower part can be turned on as an air conditioning fan alone or at the same time as the air conditioner to cool the air; at the same time, the air conditioning unit adds an electric heater between the evaporator and the lower layer of high-density fibers and the fan blades to achieve constant temperature dehumidification.

The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

The upper part of the indoor unit of the air-conditioning unit of the present invention is an air-conditioning unit, and a first electric heater 3 is added; the lower part includes a second electric heater 6, a motor, a second crossflow fan blade 4, a water pump 8, a water collection tray 7, and a high-density fiber 5 as a filter layer. FIG1 is a structural schematic diagram of the air-conditioning unit with cool but not cold air and constant temperature dehumidification according to an embodiment of the present invention. As shown in FIG1, the air-conditioning unit of the present invention is an upper and lower structure, including an upper air-conditioning fan and a lower air-conditioning fan. A water collection tray 7 is arranged below the lower air-conditioning fan. The air-conditioning unit shown divides the crossflow fan blade of the cylindrical cabinet into two small crossflow fan blades, namely the upper first crossflow fan blade 1, and the lower second crossflow fan blade 4. The two parts can be controlled to start and stop respectively.

Figure 2 is a top view of the upper air conditioner of the air-conditioning unit that blows cool air without being cold and has constant temperature dehumidification according to an embodiment of the present invention. As shown in Figure 2, an evaporator 2 is arranged on the periphery of the first cross-flow fan blade 1 on the upper part of the air conditioner, and a first electric heater 3 is arranged between the first cross-flow fan blade 1 and the evaporator 2. Refrigerant flows in the evaporator 2, and there is no evaporator at the lower part of the cylindrical cabinet of the air-conditioning unit.

Please refer to Figure 1 again. The lower part of the cylindrical cabinet of the air-conditioning unit includes a second cross-flow fan blade 4, a second electric heater 6, a high-density fiber 5, a water accumulation tray 7, a water pump 8, an overflow hole 9 and a motor (not shown). Figure 3 is a top view of the lower air-conditioning fan of the air-conditioning unit with cool but not cold air and constant temperature dehumidification according to an embodiment of the present invention. As shown in Figure 3, the outer periphery of the second cross-flow fan blade 4 is provided with a high-density fiber 5, and a second electric heater 6 is provided between the second cross-flow fan blade 4 and the high-density fiber 5.

A water collection tray is provided below the second crossflow blade 4 and the high-density fiber 5. The water collection tray 7 can collect condensed water to prevent the condensed water from dripping everywhere and causing inconvenience to the user. A water pump 8 is connected to the water collection tray 7 and to the nozzle 10 above the high-density fiber 5. The water pump 8 sprays the water in the water collection tray onto the high-density fiber 5.

When the upper air conditioner is turned on, the condensed water generated by the evaporator 2 can fall on the high-density fiber 5. At this time, if the fan is turned on, it can further cool and humidify. Therefore, the shape of the high-density fiber 5 is set to be able to receive the condensed water generated by the evaporator 2. This structure not only effectively solves the problem of condensed water discharge, but also can use condensed water to cool and humidify through the air conditioning fan, which is more environmentally friendly and energy-saving. Preferably, the high-density fiber 5 is consistent with the shape of the high-density fiber, and both are curved structures.

Further optionally, the water tray 7 is detachably connected, which is convenient for manual addition when the water volume in the water tray is small. In order to facilitate the adjustment of the water volume in the water tray, an overflow hole 9 is provided at a certain height of the water tray 7, and when the water volume in the water tray 7 exceeds a certain scale, it can be automatically discharged.

Preferably, cold water and ice crystals can be added to the water collection tray 7, and the cold water in the water collection tray 7 is continuously sprayed onto the high-density fiber 5 through the water pump 8, and the lower part of the indoor unit is used as an air-conditioning fan, which can reduce power consumption, save energy, achieve air-conditioning cooling and humidification, and improve comfort.

In the lower part of the indoor unit of the air conditioning unit, due to the addition of high-density fibers 5 and the second cross-flow fan blades 4, it can be used as a fan when there is no cold water spraying, with low power consumption, and the air passing through the high-density fibers can filter pollutants in the air and purify the indoor environment.

When the air conditioner is dehumidifying, it is often accompanied by cooling. The air conditioning unit of the present invention can turn on the internal electric heating while the air conditioner is cooling and dehumidifying. The upper and lower electric heating can be turned on simultaneously or independently. In addition, by using an infinitely variable speed fan motor, the fan speed can be changed at any time to increase the heating amount and achieve constant temperature dehumidification.

When using the air conditioner, the user can choose a variety of working modes. In the first working mode, the upper air conditioner and the lower air conditioner fan are turned on at the same time, the motor of the first cross flow fan blade 1 is turned on, the compressor of the evaporator 2 is turned on, and the upper air conditioner blows cold air. At this time, the lower air conditioner fan can turn on the second cross flow fan blade 4 and the water pump to achieve cooling and humidification, or the lower air conditioner fan only turns on the second cross flow fan blade 4 to deliver air. Both methods can achieve that the air conditioner cold air does not blow directly on people, thereby increasing comfort.

Specifically, when the upper air conditioner and the lower air conditioning fan are started at the same time, the evaporator 2 and the air conditioning fan are in an upper and lower structure, and the low-temperature condensed water on the evaporator 2 can directly drip onto the high-density fiber, which is used by the air conditioning fan to humidify the air and lower the room temperature. At this time, the water pump 8 can be temporarily turned off, and only the second crossflow fan blade 4 is turned on to save electricity. This cooling method saves more energy and also solves the problem of condensed water discharge.

In the second working mode, the air-conditioning unit is used as an air conditioner. Only the first cross-flow fan blade 1 of the upper air conditioner and the evaporator 2 arranged on the periphery can be turned on, and the first electric heater 2 and the water pump 8 are turned off. It can be used alone as an ordinary air conditioner for cooling, cooling and dehumidification.

In the third working mode, the air-conditioning unit is used as an air-conditioning fan, the compressor connected to the upper air-conditioning is turned off, the water pump 8 and the motor of the second cross-flow fan blade 4 are turned on, and ice water or ice crystals are added to the water collection tray 7 to reduce the indoor temperature and increase the indoor humidity with low power and low energy consumption.

In the fourth working mode, the air conditioning unit is used as a fan, the compressor connected to the upper air conditioner is turned off, and only the motor of the second crossflow fan blade 4 is turned on. Due to the presence of high-density fibers 5, the air can be purified, and the air output is cleaner and more comfortable than that of an ordinary fan.

In the fifth working mode, the air conditioning unit performs constant temperature dehumidification. You can choose to turn on the upper electric heater and the lower electric heater simultaneously or independently, and adjust the air volume according to the stepless speed regulation of the motor to adjust the cooling and heating to achieve constant temperature dehumidification.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
