Specifically, the specific form of the air conditioner may be various forms such as a split wall type, a split vertical type, a ceiling type, and the like. The embodiment of the utility model provides a do not carry out any restriction to the concrete form of air conditioner. Fig. 1 to 3 illustrate only an embodiment of a floor type air conditioner.

Fig. 1 is a schematic structural view of an air conditioner according to an embodiment of the present invention; fig. 2 is a schematic view of a partial structure of the inside of an air conditioner according to an embodiment of the present invention.

As shown in fig. 1 to 3, an air conditioner according to an embodiment of the present invention may generally include a housing 10, an induced air passage 31, an exhaust air passage 32, an induced air blower 91, an exhaust air blower 92, a motor 61, a first air door 41, and a second air door 42.

In which the case 10 defines a structural body of an air conditioner, which defines an accommodation space to accommodate main components of the air conditioner, such as a heat exchanger 21, a blower 22, a controller, and the like. Fig. 1 illustrates an indoor unit of a split-type floor air conditioner.

The air inducing channel 31 and the air exhausting channel 32 are separately arranged in the shell 10, and the separate means that the two are not directly communicated. The air inducing channel 31 and the air exhausting channel 32 are used to introduce the fresh outdoor air flow into the casing 10 and exhaust the indoor air to the outside, respectively. Of course, the induced air duct 31 and the exhaust air duct 32 are solid housings, and air flow passages are formed in the hollow inside thereof.

The first damper 41 and the second damper 42 are used to open and close the induced air passage 31 and the discharge air passage 32, respectively. It can be understood that when the induced air passage 31 is opened by the first damper 41, the induced air process can be performed normally. If the induced air passage 31 is closed by the first damper 41, the induced air process cannot be performed, and fresh indoor air cannot enter the casing 10. The same applies to the exhaust duct 32, and will not be described in detail.

The induced draft fan 91 is disposed in the induced draft passage 31. The function of the induced draft fan 91 is to promote the fresh air flow in the induced draft channel 31 to flow towards the indoor direction. The exhaust fan 92 is disposed in the exhaust duct 32. The exhaust fan 92 functions to cause the indoor air in the exhaust duct 32 to flow in the outdoor direction.

The motor 61 is mounted to the housing 10 so as to be detachably mounted to the housing 10. The motor 61 may be a fixed frequency motor or a variable frequency motor. The motor 61 includes two rotating shafts 611 and 612, which are respectively connected to the induced air fan 91 and the exhaust air fan 92 to drive the induced air fan 91 and the exhaust air fan 92 to synchronously operate. That is, if the induced air passage 31 and the exhaust air passage 32 are both opened, the induced air process and the exhaust air process are synchronized.

The embodiment of the utility model provides an in, the air conditioner has set up induced air passageway 31 and air exhaust passageway 32, and is provided with induced air fan 91 and air exhaust fan 92 in it respectively, when utilizing induced air passageway 31 to introduce indoor new trend, utilizes air exhaust passageway 32 to discharge the room air to outdoor to realize the balance of indoor external pressure, accelerated the speed that indoor air current updates. In addition, the induced air fan 91 and the exhaust air fan 92 are driven by the same motor 61, so that the structure is simpler, and the control logic is also simplified.

The inventor finds, compares in prior art and only opens a new trend fan air supply, utilizes the scheme that door crack, window seam were aired exhaust, the embodiment of the utility model provides a make induced air fan 91 and air exhaust fan 92 open simultaneously and can greatly accelerate the air current renewal speed, also shortened the air current renewal time, also made the operating duration of induced air fan 91 and air exhaust fan 92 shorter. Thus, although operating both fans at the same time increases power, the overall fan power consumption is still reduced because the operating time is shortened.

Furthermore, the air conditioner of the embodiment of the present invention is provided with the first damper 41 and the second damper 42 to respectively open and close the induced air passage 31 and the exhaust air passage 32. Thus, although the induced air fan 91 and the exhaust air fan 92 are always operated simultaneously, only the exhaust course can be operated by closing the induced air passage 31. At this time, the exhaust fan 92 is operated but the exhaust duct 32 does not exhaust the air to the outside. Similarly, the air conditioner can only operate the induced draft process by only closing the exhaust channel 32, and at this time, the induced draft fan 91 operates but the induced draft channel 31 does not induce the air indoors. Thus, in some cases, the user does need to only draw or exhaust air, and air conditioning can be achieved.

In some embodiments of the present invention, as shown in fig. 2 and 3, the motor 61 may be disposed outside the induced air passage 31 and the exhaust air passage 32 and between them. Two rotation shafts of the motor 61 extend from both sides (e.g., front and rear sides) of the motor 61 and respectively extend into the induced air duct 31 and the exhaust air duct 32 to respectively connect the induced air fan 91 and the exhaust air fan 92.

The present embodiment arranges the motor 61 outside the air inducing channel 31 and the air discharging channel 32 so that it does not occupy the space of the air inducing channel 31 and the air discharging channel 32, and also avoids the resistance to the flow of the air current.

In some embodiments of the present invention, as shown in fig. 1 and 2, the housing 10 defines isolated heat exchange chambers 11 and non-heat exchange chambers 12.

For example, for the embodiment shown in fig. 2, in which the air conditioner is a vertical air conditioner, the non-heat exchange chamber 12 may be located below the heat exchange chamber 11, so as to make the air outlet 112 of the heat exchange chamber 11 higher, so as to prolong the air supply distance of the heat exchange airflow. Further, the air discharge duct 32 is located below the air introducing duct 31 so that the air introducing duct 31 is closer to the heat exchange chamber 11.

The heat exchange chamber 11 is used for blowing out a heat exchange air flow. When the air conditioner is in a refrigeration mode, the heat exchange airflow is cold air airflow. When the air conditioner is in a heating mode, the heat exchange airflow is hot air airflow. The housing 10 is provided with an air outlet 112 for blowing out heat exchange air flow. Specifically, the heat exchange air flow can be directly prepared from the heat exchange chamber 11, and the heat exchanger 21 and the fan 22 of the air conditioner can be arranged in the heat exchange chamber 11 as shown in the indoor unit of the vertical air conditioner in fig. 2. The heat exchanger 21 is connected to a heat exchanger, a compressor, a throttle device, and other components of the outdoor unit through pipes to form a vapor compression refrigeration cycle system, and a refrigerant flows through the inside thereof to perform cooling/heating. In some alternative embodiments, it is also possible to provide no heat exchanger 21, only the fan 22, or no fan in the heat exchange chamber 11, so that the heat exchange chamber 11 introduces the heat exchange air flow from another space and then blows out the heat exchange air flow.

The non-heat exchange chamber 12 has a return air opening 121 communicating with the indoor environment. The induced air channel 31 and the exhaust channel 32 are arranged in the non-heat exchange chamber 12, the outlet 312 of the induced air channel 31 is communicated with the heat exchange chamber 11, and the inlet 321 of the exhaust channel 32 is communicated with the non-heat exchange chamber 12. Therefore, the fresh air flow introduced by the induced air channel 31 is discharged into the heat exchange cavity 11 to be mixed with the heat exchange air flow, and the temperature of the fresh air flow is closer to that of the heat exchange air flow. The phenomenon that fresh air with too low temperature in winter or fresh air with too high temperature in summer enters the indoor environment to have adverse effect on the indoor environment temperature and cause discomfort to a human body is avoided.

In some embodiments of the present invention, as shown in fig. 2, a heat exchanger 21 and a fan 22 are disposed in the heat exchange chamber 11, and an outlet 312 of the induced air passage 31 is communicated to an upstream side of the heat exchanger 21. Therefore, the fresh air flow exchanges heat with the heat exchanger 21 firstly and then enters the indoor environment, and fresh air with too low temperature in winter or fresh air with too high temperature in summer is prevented from entering the indoor environment. The air inducing passage 31 may be located rearward of the air discharging passage 32 so that the outlet 312 of the air inducing passage 31 is located further rearward so as to communicate to the upstream side of the heat exchanger 21 (typically, the rear side of the heat exchanger 21).

In some embodiments of the present invention, as shown in fig. 2, the casing 10 further has a fresh air inlet 311 connected to the inlet end of the induced air channel 31, and the fresh air inlet 311 is connected to the fresh air inlet pipe 81 connected to the outdoor environment. The casing 10 is further provided with a fresh air outlet 322 connected to the outlet end of the air exhaust channel 32, and the fresh air outlet 322 is used for being connected to a fresh air exhaust pipe 82 connected to the outdoor environment. In the embodiment, the fresh air inlet pipe 81 and the fresh air exhaust pipe 82 are detachably mounted on the independent part of the housing 10, so that the design, manufacture and transportation of the air conditioner can be more convenient.

Further, as shown in fig. 2, the first damper 41 may be provided at the fresh air inlet 311, and the second damper 42 may be provided at the fresh air outlet 322.

Further, the first damper 41 may be configured to rotatably open and close the induced air passage 31, and the second damper 42 may be configured to rotatably open and close the discharge air passage 32. Specifically, as shown in fig. 2, the first damper 41 may be made in a plate shape with its axis extending vertically, which is driven by a stepping motor 51. The second damper 42 may be made in the form of a plate whose axis extends vertically, and which is driven by a stepping motor 52.

In some embodiments, the induced air fan 91 is a centrifugal fan or an axial flow fan, and the exhaust air fan 92 is a centrifugal fan or an axial flow fan.

Preferably, as shown in fig. 2, for example, both the induced air fan 91 and the exhaust air fan 92 may be centrifugal fans.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
