Detailed ways

In order to make those skilled in the art better understand the technical solution of the utility model, the utility model will be further introduced in detail below in conjunction with the accompanying drawings.

The indoor unit provided by the embodiment of the present invention, the air conditioner including the indoor unit, and even the fresh air system or other air conditioning system including the indoor unit are all systems that achieve temperature regulation through the reverse Carnot cycle, that is, the temperature regulating device A temperature regulating device including components such as a compressor, a condenser, an evaporator, and a valve system. One of the condenser and the evaporator is located in the indoor unit, and the other is located in the outdoor unit. Under different working conditions, such as cooling or heating, the condenser and evaporator work in different ways. In this embodiment, the condenser or evaporator installed in the outdoor unit is called a heat exchanger. When the indoor cooling needs, it is used to dissipate heat to the outside, and when the indoor heating needs, it is used to absorb heat from the outdoor side.

As shown in Figure 1-2, the outdoor unit of an air conditioner provided by the utility model includes a shell 1, a heat exchanger arranged in the shell 1, and an indoor exhaust duct 2. The heat exchange At least part of the device is located in the exhaust range of the indoor exhaust duct.

Specifically, the air inlet of the indoor exhaust duct 2 is located on the indoor side, which is used to discharge the return air from the indoor side to the outside, and part or all of the heat exchanger of the outdoor unit is located within the exhaust range of the indoor exhaust duct 2 , in terms of structure, it may be that part of the heat exchanger is located inside the indoor exhaust duct 2, that is, at least part of the heat exchanger is embedded in the indoor exhaust channel, so that the indoor return air blows directly through the heat exchanger; it may also be The heat exchanger and the exhaust outlet 2.1 of the indoor exhaust duct 2 are arranged oppositely, and the return air blown out by the exhaust outlet 2.1 is directly blown to the heat exchanger.

For the outdoor unit provided in this embodiment, when cooling is required indoors, the heat exchanger of the outdoor unit is used to dissipate heat to the outside, and the heat exchanger dissipates high temperature to the outdoor air through the fan. Generally, the indoor temperature is lower than the outdoor temperature, and the lower temperature indoor return air is used to replace the higher temperature outdoor air to accept the high temperature of the heat exchanger, which makes the heat exchange efficiency of the heat exchanger higher and also utilizes the The energy of the indoor return air; when heating is required indoors, the temperature of the heat exchanger of the outdoor unit is lower, which is used to absorb the heat of the outdoor air, and the heat exchanger distributes the low temperature to the outdoor air. The temperature of the heat exchanger is higher than the outdoor temperature, and the indoor return air with a higher temperature is used to replace the outdoor air with a lower temperature to relieve the low temperature of the heat exchanger, so that the heat exchange efficiency of the heat exchanger is higher, and the indoor return air is also used. Energy is more important at this time. In relatively low temperature winter, when the temperature of the heat exchanger is below zero, frost will form on the heat exchanger, making it lose its heat exchange capacity. At this time, in order to defrost, the air conditioner It will enter the defrosting mode, and the defrosting mode will interrupt the heating of the room and switch to cooling, which makes the user's experience significantly lower. The probability of reducing the temperature of the heat exchanger to below zero also reduces the probability of frosting and defrosting, which improves the user experience.

In this embodiment, further, the cover plate 3 is also provided with an exhaust flow control mechanism 4, the exhaust flow control mechanism 4 is a mechanism that can control the return air flow, such as a valve or a similar flow control mechanism, which It is used to control the exhaust volume. On the one hand, it is used to control the residence time of the return air in the above-mentioned accommodating cavity, and on the other hand, it is used to prevent dust and other sundries from entering the accommodating cavity. Preferably, the flow regulating mechanism is a motor 4.1 and a louver 4.2 driven by the motor 4.1, the motor 4.1 drives the louver 4.2 to rotate, and the louver 4.2 rotates to open or close the accommodating cavity. More preferably, the exhaust port 2.1 of the indoor exhaust duct 2 is located in the middle area of the cover plate 3, and there are two flow regulating mechanisms, and the two flow regulating mechanisms are separately placed in the housing 1 The opposite sides on the upper side, so that the direction of the return air is more balanced.
