Detailed Description

It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application.

An embodiment of the present application provides an air conditioner, please refer to fig. 1, which includes a body 11, an air intake channel 12, and a flow distribution mechanism. Referring to fig. 1, the body 11 is formed with an air duct and an indoor air outlet 11a, that is, air flow in the air duct enters the room through the indoor air outlet 11 a. Referring to fig. 1 to 4, the air intake channel 12 has an air outlet 12c, a fresh air inlet 12a and a return air inlet 12b, and the air duct communicates the air outlet 12c and the indoor air supply outlet 11 a; at least a part of the flow distribution mechanism is movably disposed in the air intake channel 12 to selectively shield the fresh air inlet 12a and the return air inlet 12 b.

The air conditioner includes a first operation mode, a second operation mode, and a third operation mode. In the first operation mode, please refer to fig. 4, the flow distribution mechanism closes the air return opening 12b and opens the fresh air opening 12a, so that fresh air enters the air intake channel 12 through the fresh air opening 12 a; in the second operation mode, referring to fig. 3, the flow distribution mechanism closes the fresh air inlet 12a and opens the return air inlet 12b, so that the indoor return air enters the air inlet channel 12 through the return air inlet 12 b; in the third operating mode, referring to fig. 2, the flow distribution mechanism adjusts the air intake of the fresh air inlet 12a and the air return inlet 12b, and the air intake channel 12 proportionally feeds air from the fresh air inlet 12a and the air return inlet 12 b.

The air conditioner of this application embodiment, through the motion of flow distribution device's at least partly in inlet air duct 12 for the air conditioner has multiple mode, can satisfy different use scenes, can not only solve the problem of the indoor air vexation, peculiar smell, also can reduce heat exchange power, reaches both to satisfy the comfort level and energy-conserving purpose.

Specifically, when indoor pollutant concentration is great or the air is comparatively vexed, the air conditioner can be in first mode of operation, and under this mode, the air that gets into indoorly from indoor supply-air outlet 11a all comes from outdoor new trend, can not carry out indoor air circulation, consequently, can be fast, a large amount of suction outdoor new trend, can improve indoor air quality in short time rapidly. When the kitchen has no oil smoke or has less oil smoke and the air quality is still enough, the air conditioner can be in the second working mode, and in the second working mode, all the air entering the room from the indoor air supply outlet 11a comes from indoor return air, namely indoor air internal circulation, and the proper temperature can be maintained only by a small amount of heat exchange power, so that the energy consumption is low. When a proper amount of fresh air needs to be sucked, the air conditioner is in a third working mode, in the third working mode, air enters from the fresh air inlet 12a and the return air inlet 12b in proportion, the supplemented fresh air can solve the problems of stuffiness and peculiar smell of indoor air, and because one part of the air volume entering the air inlet channel 12 is the indoor return air, the temperature of the fresh air can be increased after the indoor return air and the fresh air are mixed, therefore, the mixed air flow can be cooled to the room temperature only by lower heat exchange power, and the purposes of comfort and energy conservation are achieved.

It can be understood that, when the air conditioner is installed indoors, the fresh air duct 141 may be externally connected to the fresh air opening 12a, and outdoor fresh air may be introduced into the fresh air opening 12a through the fresh air duct 141. If the return air inlet 12b does not directly face the indoor space, a return air duct 142 may be externally connected to the return air inlet 12b, and the indoor air is introduced into the return air inlet 12b from a suitable position in the room through the return air duct 12. If the indoor air outlet 11a is not directly connected to the indoor space, the air outlet 11a may be externally connected to the air pipe 143, and the air may be supplied to a suitable position in the room through the air pipe 143.

For example, in the third operation mode, the ratio τ 1 of the fresh air volume entering from the fresh air port 12a to the total air volume of the air intake duct 12 can be continuously changed between more than 0 and less than 1. Specifically, the fresh air volume entering from the fresh air inlet 12a is Qa, the return air volume entering from the return air inlet 12b is Qb, the total air volume of the air intake duct 12 is Q, Q is Qa + Qb, and τ 1 is Qa/(Qa + Qb). It should be noted that, when the ratio τ 1 is 0, the fresh air amount Qa is 0 at this time, that is, the fresh air inlet 12a is closed, and the total air amount of the air inlet channel 12 comes from the return air inlet 12b, that is, Q is Qb, and at this time, the air conditioner is in the second operation mode. When the ratio τ 1 is 1, the return air amount Qb is 0, i.e., the return air inlet 12b is closed, and the whole air amount of the air inlet channel 12 comes from the fresh air inlet 12a, i.e., Q ═ Qa, and the air conditioner is in the first operation mode.

For example, in the third operation mode, the ratio τ 2 of the amount of return air entering from the return air inlet 12b to the total amount of air of the air intake passage 12 can be continuously changed between more than 0 and less than 1. It should be noted that τ 1+ τ 2 is 1, that is, when τ 1 is 0, τ 2 is 1; when τ 1 is 1, τ 2 is 0.

The air conditioner can steplessly adjust the fresh air volume, and a user can steplessly adjust the fresh air volume according to actual use requirements, so that the user experience is improved.

In one embodiment, referring to FIGS. 2 to 4, the sum of the flow area S2 of the return air inlet 12b and the flow area S1 of the fresh air inlet 12a is not greater than the flow area S of the air inlet channel 12, i.e., S ≧ S1+ S2, so as to prevent the air inlet channel 12 from forming a throttling effect and reduce the wind energy loss.

The air intake channel 12 may be disposed outside the machine body 11, or may be integrated in the machine body 11, which is not limited herein. For example, referring to fig. 1, the air inlet channel 12 is disposed outside the machine body 11, the machine body 11 is provided with an interface, and an air outlet end of the air inlet channel 12 is connected to the interface, in this embodiment, the air inlet channel 12 does not occupy a space inside the machine body 11, so as to avoid an additional increase in the external dimension of the machine body 11, and make the structure of the machine body 11 more compact.

In this embodiment, the valve plate 13 can adjust the flow rate and guide the air flow, specifically, the air flow from the fresh air inlet 12a turns 90 ° under the blocking of the valve plate 13 and then flows toward the air outlet 12c, but does not flow directly to the return air inlet 12b, so as to avoid the formation of vortex and backflow at the return air inlet 12 b. Similarly, the air flow from the return air inlet 12b turns by about 90 ° under the blockage of the valve plate 13 and flows toward the air outlet 12c, but does not directly flow to the fresh air inlet 12a, so as to avoid the formation of vortex and backflow at the fresh air inlet 12 a.

In one embodiment, the driver can drive the valve plate 13 to remain in any position over a range of rotational travel. Therefore, the proportion of the fresh air volume in the total air volume can be adjusted steplessly. In another embodiment, the driving member is capable of driving the valve plate 13 to rotate to switch between a plurality of preset positions. That is to say, the valve plate 13 can only stay at a few determined preset positions, in this embodiment, the proportional adjustment of the fresh air volume presents a certain gear feeling, and the proportion of the fresh air volume is different in different gears.
