In the related art, in order to meet the use demands of users, the functions of the vertical air conditioner are increasingly and variously applied, and besides the basic refrigerating and heating functions of the air conditioner, the vertical air conditioner also has some additional special functions, such as purification, fresh air, mosquito removal, deodorization, sterilization, humidification, voice and the like, and correspondingly, the load power consumption of a control main board of the indoor unit of the air conditioner is continuously increased, so that the control main board of the air conditioner is easier to generate heat in the use process of the air conditioner, and the use safety of the control main board is correspondingly reduced.

In order to overcome the problems, the embodiment provides a vertical air conditioner indoor unit and an air conditioner, wherein an electric control box group comprising a control main board is arranged below an indoor unit body, an air guide channel and a heat dissipation fan are arranged, indoor air is sucked into the air guide channel through a second air inlet, and air entering the air guide channel is discharged through a second air outlet, so that heat dissipated by the electric control box group is taken away by the air in the air guide channel, the electric control box group is cooled, and the temperature of the electric control box group can be maintained in a proper range, so that the use safety of the air conditioner is ensured.

The structure and functions of the air conditioner indoor unit and the air conditioner provided in this embodiment are illustrated below with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of a vertical indoor air conditioner according to an embodiment of the present application, where arrows in fig. 1 indicate gas flow directions. Referring to fig. 1, the indoor unit of the vertical air conditioner provided in this embodiment, like the existing indoor unit of the vertical air conditioner, includes a casing 100, an indoor unit body 600 and an electric control box set 200, wherein the indoor unit body 600 and the electric control box set 200 are installed in the casing 100, and an air outlet 101 for air outlet of the indoor unit body 600 is provided on the casing 100, wherein the indoor unit body 600 mainly includes a through-flow fan and an air outlet for discharging hot air or cold air to the outside through the air outlet and the air outlet 101, and other components on the indoor air conditioner, such as a heat exchanger, a filter screen, a compressor, etc., can be set according to conventional manners in the art, and will not be repeated here.

The biggest difference between this example and the existing vertical air conditioner indoor unit is that the electric control box body set 200 is installed below the indoor unit body 600, and the shell 100 is provided with the air inlet two 102 and the air outlet two 103, the air outlet two 103 and the air outlet one 101 are located at the same side of the shell 100, and the air outlet two 103 is located below the air outlet one 101, and an air guide channel for communicating the air inlet two 102 and the air outlet two 103 is formed between the electric control box body set 200 and the shell 100, which can be understood that the outer surface of the electric control box body set 200 is directly contacted with the air in the air guide channel, and a heat dissipation fan 300 for driving the air to flow from the air inlet two 102 to the air outlet two 103 is arranged in the air guide channel, so that the air flows to take away the heat emitted by the electric control box body set 200.

The heat dissipation fan 300 may directly use an existing fan, so long as the air can be sucked into the air guiding channel from the air inlet two 102 and sent out of the air guiding channel from the air outlet two 103. Illustratively, the heat dissipation blower 300 may include a fan, a motor, and a volute, the fan being mounted within the volute, the motor driving the fan to rotate, thereby driving air through the volute. Of course, when the cooling fan 300 is installed, part or all of the cooling fan may be located in the air guiding channel, so long as the cooling fan can suck indoor air into and send indoor air out of the air guiding channel.

In the use process of the air conditioner, only the heat dissipation fan 300 is required to be started, the heat dissipation fan 300 can suck the air in the air guide channel from the air inlet II 102, the air in the air guide channel can suck the heat emitted by the electric control box body group 200, and then the air leaves the air guide channel from the air outlet II 103 to enter the room under the driving of the heat dissipation fan 300.

Firstly, the heat dissipation fan 300 sucks the air around the indoor unit body 600 into the air guide channel from the air inlet II 102, the air entering the air guide channel can suck the heat emitted by the electric control box body group 200, the temperature of the electric control box body group 200 is reduced, the overhigh temperature of the electric control box body group 200 is avoided, and the use safety of the air conditioner is improved.

Secondly, the air entering the air guide channel also can disturb the air around the electric control box body group 200, so that the air flow around the electric control box body group is accelerated, and the volatilization of the heat of the electric control box body group 200 is further accelerated.

Furthermore, the air leaving from the second air outlet 103 is mixed with the air blown out from the first air outlet 101 by the indoor unit body 600, so that the user experience can be effectively improved, namely:

in winter, the air blown out from the second air outlet 103 absorbs the heat emitted by the electric cabinet group 200, and compared with the indoor air, the temperature rises, and when the air leaves from the second air outlet 103, the air can be mixed with the hot air blown out from the first air outlet 101, so that the hot air of the air conditioner is faster when heating in winter, the second air outlet 103 fills the blank that no hot air exists below the indoor unit body 600, the upper and lower temperature difference of the air outlet side of the air conditioner is effectively reduced, and the user experience is improved;

in summer, the air blown out from the second air outlet 103 absorbs the heat emitted by the electric cabinet set 200, and compared with the indoor air, the temperature of the air rises, and when the air leaves from the second air outlet 103, the air can be mixed with the cold air blown out from the first air outlet 101 to become cool air, so that the air blown out from the air conditioner indoor unit is cool and not cool, the problems of low air outlet temperature and uncomfortable feeling of a user of the air conditioner indoor unit in summer are solved, and the user experience is effectively improved.

In addition, the heat dissipation fan 300 absorbs external air from the second air inlet 102 and discharges air from the second air outlet 103, so that indoor air at the lower part of the air conditioner indoor unit can be disturbed in an auxiliary manner, and the indoor air flow is accelerated by the auxiliary indoor unit body 600, so that indoor temperature change can be quicker and more uniform during refrigeration or heating, the desired comfort temperature of a human body can be reached more quickly, and the comfort level of the air conditioner indoor unit in use can be improved.

Based on the above embodiment, the air inlet of the heat dissipation fan 300 and the electric control box set 200 are arranged oppositely in the vertical direction, that is, the air inlet of the heat dissipation fan 300 is opposite to the electric control box set 200. Such setting mode, when cooling fan 300 starts, can produce stronger suction in electric cabinet group 200 department, be favorable to sucking away impurity such as dust on the electric cabinet group 200, avoid it to gather on electric cabinet group 200 to can protect electric cabinet group 200, promote the result of use of air conditioner.

Based on the above embodiment, the second air inlet 102 is disposed below the second air outlet 103, so that hot air is easy to rise and cold air is easy to sink, and the temperature of the air entering the second air inlet 102 is relatively low, so as to improve the heat dissipation effect. In addition, the second air inlet 102 can be provided at other positions of the housing 100 for assisting the air inlet, for example, the second air inlet 102 is provided at the opposite side, so as to expand the air inlet direction and the air quantity, and facilitate improving the heat dissipation effect of the electric cabinet set 200.

On the basis of the above embodiment, the heat dissipation fan 300 is located between the indoor unit body 600 and the electric cabinet set 200, the second air inlet 102 is located outside the electric cabinet set 200, and the second air outlet 103 is located above the electric cabinet set 200. That is, the second air outlet 103 is adjacent to the first air outlet 101, so that the air exhausted from the second air outlet 103 can be better mixed with the cold air or the hot air blown out from the first air outlet 101, thereby relieving the temperature difference between the air blown out from the first air outlet 101 and the indoor air.

In summer, the air outlet temperature of the air conditioner is adjusted to 16 ℃, if the temperature around the indoor air conditioner is 27 ℃, after the heat dissipation fan 300 is started, the heat dissipation fan 300 guides the air around the air conditioner to enter the air guide channel through the air inlet two 102 so as to absorb the heat emitted by the electric cabinet group 200, the absorbed air leaves the air guide channel through the air outlet two 103 under the driving of the heat dissipation fan 300, and the temperature of the air discharged by the air outlet two 103 is higher than that of the air outlet one 101 because the air outlet two 103 is adjacent to the air outlet one 101, at the moment, the air of the air outlet two 103 rises, and the air of the air outlet one 101 sinks, so that the air outlet temperature perceived by a human body at the air outlet can be raised to about 21 ℃ after the cold air blown by the indoor air conditioner and the hot air discharged by the air outlet two 103 are fused, thereby the problem that the human body is uncomfortable due to the cold local part of the human body can be obtained, and the user experience can be effectively improved while the air conditioner is assisted in refrigerating. Of course, it should be noted that not all air conditioners are illustrated herein, and the outlet air temperature is 21 ℃, and the specific parameters of the air conditioner and the cooling fan 300 are also relevant.

Meanwhile, an air deflector can be installed at the second air outlet 103 to guide the blowing direction, so that the fusion degree of the air exhausted by the second air outlet 103 and the air exhausted by the indoor unit body 600 can be controlled, and the final air outlet sensing air outlet temperature can be adjusted.

On the basis of the above embodiment, the heat dissipation fan 300 is fixed on a supporting frame 500, and of course, the connection mode between the heat dissipation fan 300 and the supporting frame 500 may be a bolt connection mode or other connection modes, as long as the heat dissipation fan 300 is firmly fixed on the supporting frame 500, and the supporting frame 500 is fixed on the bracket 700, where the bracket 700 may be additionally arranged on the housing 100, or may be a structure of the air conditioning indoor unit itself, such as a base of the air conditioning indoor unit, an air conditioning upright post support or an air conditioning body supporting frame 500 frame, and of course, how to fix may be selected according to the actual structure of the air conditioning indoor unit, so long as the heat dissipation fan 300 can be stably supported in the use process.

In addition, the supporting frame 500 divides the air guide channel into an air channel I402 and an air channel II 401 which are arranged in an up-down relationship, the air inlet II 102 is communicated with the air channel II 401, and the air outlet II 103 is communicated with the air channel I402; an air inlet III 502 is formed in the bottom of the supporting frame 500, the air inlet III 502 is communicated with the air channel I402 and the air channel II 401, and the heat dissipation fan 300 drives air in the air channel II 401 to pass through the air inlet III 502, enter the air channel I402 and leave the air channel I402 through the air outlet II 103. Therefore, no additional components are required to be installed in the casing 100, so that the air entering the air guide channel from the air inlet II 102 can be completely conveyed away from the air guide channel through the heat dissipation fan 300, and the circulation effect of the air guide channel and the external air is improved.

In addition, the third air inlet 502 is arranged opposite to the electric control box body set 200 in the vertical direction, so that impurities such as dust on the electric control box body set 200 can be better sucked away, and the electric control box body set 200 is protected.

Meanwhile, the air outlet III 104 connected with the air duct I402 can be arranged on the shell 100, and the air outlet III 104 is positioned on one side of the air duct I402 far away from the air outlet II 103, so that the requirement that a part of the electric cabinet body group 200 needs large air quantity for heat dissipation is met. In addition, when the air conditioner is used, the second air outlet 103 blows towards the front of the air conditioner, the third air outlet 104 blows towards the rear of the air conditioner, the front can be mixed with air of the air outlet to disturb air in front of the air conditioner, and the air discharged by the third air outlet 104 can disturb air in rear of the air conditioner, so that the air flow speed around the air conditioner is further improved. Of course, a cover plate can be further configured for the third air outlet 104, and the third air outlet 104 can be opened or closed by opening or closing the cover plate, so that the cover plate is opened when needed, the air quantity is increased, the heat dissipation is accelerated, and the cover plate can be closed when the large air quantity is not needed for heat dissipation, so that the third air outlet 104 is not provided with air any more, and the mixing effect of the air exhausted from the second air outlet 103 and the air exhausted from the first air outlet 101 is not influenced.
