The utility model discloses in fact put forward a machine and include the air conditioner of this machine in floor standing air conditioning. The following description takes a floor type air conditioner indoor unit as a specific embodiment.

Referring to fig. 2, the floor type air conditioner indoor unit 10 includes a casing 11, a heat exchanger, a volute assembly and a wind wheel, the heat exchanger and the volute assembly enclose to form a heat exchange air duct, and the wind wheel is disposed in the heat exchange air duct. The shell 11 is provided with a main air outlet 110 communicated with the heat exchange air duct.

Referring to fig. 1 to 4, a fresh air module 12 is further installed in the housing 11, the fresh air module 12 has two auxiliary air outlets 120, and the fresh air module 12 is used for introducing outdoor air into a room through the auxiliary air outlets 120; the two auxiliary outlets 120 are respectively located above and below the main outlet 110, so that when the main outlet 110 is out of wind, the airflow flowing out from the auxiliary outlets 120 is mixed with the airflow flowing out from the main outlet 110.

The wind wheel in the floor type air-conditioning indoor unit 10 may be an axial flow wind wheel, a cross flow wind wheel, a centrifugal wind wheel, or a mixed flow wind wheel, which is not limited herein. The mode of introducing the outdoor air into the room by the fresh air component 12 can be active induced draft or passive induced draft. That is, the fresh air fan 12a may be disposed in the fresh air component 12, or the fresh air fan 12a may not be disposed therein.

For embodiments in which the fresh air blower 12a is provided, when the air conditioner is operating, the fresh air blower 12a draws outdoor air into the room so that it can actively mix with the airflow blown out by the main outlet 110.

For the embodiment without the fresh air fan 12a, when the air conditioner is running, because the flow velocity of the airflow blown out from the main air outlet 110 is large, a negative pressure region is formed in front of the main air outlet 110 (the flow velocity is large, the air pressure is low), and the airflow from the auxiliary air outlet 120 is collected towards the front of the main air outlet 110 under the action of the negative pressure. Especially, when the auxiliary air outlet 120 is close to the main air outlet 110, the negative pressure air supply effect is particularly obvious.

The shapes of the main outlet 110 and the auxiliary outlet 120 are not limited, and the main outlet 110 may be substantially square, may be long-strip-shaped extending in the up-down direction, may be strip-shaped extending in the horizontal direction, or may be circular.

The shape of the auxiliary air outlet 120 may be circular, a strip-shaped arrangement extending along the horizontal direction, or an arc-shaped arrangement.

The shapes of the main outlet 110 and the auxiliary outlet 120 may be combined according to actual requirements.

For example, when the main outlet 110 is disposed in a circular shape, the auxiliary outlet 120 may be disposed in a strip shape extending along a horizontal direction, or disposed in an arc shape (below and/or above the main outlet 110).

When the main outlet 110 is square, the auxiliary outlet 120 may be horizontally extending in a strip shape or arc shape (below and/or above the main outlet 110).

When the main outlet 110 is a long strip extending in the vertical direction, the auxiliary outlet 120 may be a long strip extending in the width direction (horizontal direction) of the main outlet 110.

When the auxiliary outlet 120 is located above the main outlet 110, if the floor type air conditioning indoor unit 10 is in a heating mode (the main outlet 110 supplies hot air), since the air flow blown out from the upper portion of the main outlet 110 is mixed with outdoor fresh air, the temperature of the mixed air flow is relatively low, and thus, the air flow with relatively low temperature presses the hot air flow located in the middle of the main outlet 110, so that the hot air flow can be supplied farther, the indoor is easier to heat, and the indoor temperature can be more uniform.

When the auxiliary outlet 120 is located below the main outlet 110, if the floor type air conditioning indoor unit 10 is in the cooling mode, the temperature of the mixed air flow is higher because the air flow blown out from the lower portion of the main outlet 110 is mixed with fresh outdoor air. Therefore, under the condition that the air flow with higher temperature is supported (the hot air flow is light and easy to rise, and the cold air flow is heavy and easy to fall), the cold air flow from the middle part of the air outlet is not suitable to fall downwards, so that the cold air flow can be used for supplying air farther, the indoor space is easier to refrigerate, and the temperature is more uniform.

Of course, no matter the floor type air conditioning indoor unit 10 is in the heating or cooling mode, the two auxiliary outlets 120 may be opened together, so that one of the auxiliary outlets 120 may support the cold air flow or press the hot air flow, and the other auxiliary outlet 120 may introduce more fresh air.

The technical scheme of the utility model through add new trend subassembly 12 in floor type air conditioner indoor set 10, introduce indoor with outside fresh air through new trend subassembly 12 to mix with the air current that main air outlet 110 blew off, thereby make the air that blows off fresher on the one hand, on the other hand has still avoided the air current supercooling or the overheated problem that main air outlet 110 blew off.

In the above embodiment, please refer to fig. 1, fig. 5a and fig. 5b, it is preferable that the main outlet 110 extends along the vertical direction, and for the positions of the main outlet 110 and the auxiliary outlet 120, if the main outlet 110 and the auxiliary outlet 120 are far deviated from the horizontal direction (the width direction of the main outlet 110), the airflow flowing out from the auxiliary outlet 120 is difficult to be collected in front of the main outlet 110, which is not favorable for mixing the air. In view of this, in the present embodiment, the vertical projection of the main outlet 110 in the vertical direction at least partially overlaps with the vertical projection of the auxiliary outlet 120 in the vertical direction. For example, the auxiliary outlet 120 is located right above the main outlet 110 (in the main outlet 110 and the auxiliary outlet 120, the vertical projection of one is completely overlapped by the projection of the other), or a half of the vertical projection of the auxiliary outlet 120 is overlapped by the vertical projection of the main outlet 110.

For the passive air supply mode of the fresh air component 12, the distance between the auxiliary air outlet 120 and the main air outlet 110 cannot be too far, otherwise, the air outlet of the auxiliary air outlet 120 is not greatly affected by the negative pressure formed in front of the main air outlet 110.

In view of this, referring to fig. 1, the auxiliary outlet 120 is disposed adjacent to the main outlet 110, so that when the main outlet 110 is exhausted, the airflow flowing out of the auxiliary outlet 120 flows to the front side of the main outlet 110 under the negative pressure formed at the front side of the main outlet 110.

Referring to fig. 5a and 5b, for the proximity degree between the main outlet 110 and the auxiliary outlet 120, the smaller the distance between the main outlet 110 and the auxiliary outlet 120 is, the larger the influence of the airflow blown out by the main outlet 110 on the auxiliary outlet 120 is, and in order to make the airflow blown out by the auxiliary outlet 120 larger, the distance between the auxiliary outlet 120 and the main outlet 110 is d, and d is less than or equal to 50 cm. For example, d is 0.1cm (about the thickness of one separator), 0.5cm, 1cm, 3cm, 8cm, 10cm, 12cm, 15cm, 18cm, 20cm, 25cm, 30cm, 35cm, 40cm, 45cm, 50cm, or the like.

For the embodiment of actively blowing air at the auxiliary air outlet 120, the fresh air fan 12a may be a cross-flow fan, an axial-flow fan or a centrifugal fan, outdoor air flow is sucked by the fresh air fan 12a and then discharged, and the discharged air flow is collected toward the front of the main air outlet 110 under the negative pressure.

First draft tube 12e₁And a second induced draft duct 12e₂The advantage of separately with outdoor intercommunication lies in that two new trend fans 12a do not have the problem of robbing the wind to when introducing new trend, the new trend is sufficient, and two auxiliary air outlets 120 air-out are even.

(2) second draft tube 12e₂And a first induced draft pipe 12e₁Connected (see fig. 10). The design isIn consideration of the convenience of the running pipe, here, the first draft pipe 12e₁And the second induced draft tube 12e₂Can be collected and then communicated with the outside. For example, the first draft tube 12e₁And penetrating through the wall to the outside. Although this embodiment may affect the supply of fresh air to the room, it is relatively convenient to install the two ducts, for example, only one through-wall hole is needed, and the hole diameter of the through-wall hole is not necessarily too large. In order to avoid the interference between the induced draft tube and the room in space, the induced draft tube is not too high in general. Therefore, here, the first draft tube 12e is used₁The wall penetration is preferred. Second draft tube 12e₂Can extend downwards along the outer wall or the inner wall of the floor type air conditioner indoor unit 10 (see fig. 12), and then is connected with a first air guiding pipe 12e₁And (4) communicating. In order to make the second induced draft tube 12e₂The installation is firmer, the second induced draft tube 12e₂May be formed integrally with the housing, or the inner wall of the housing may be provided with a duct groove (integrally formed with the outer wall), and the second air guiding duct 12e₂Is arranged in the pipe trough; or a second induced draft tube 12e₂Extends downwardly along the outer wall of the housing, thus facilitating a second induced draft duct 12e₂Replacement and cleaning; also can be a second induced draft tube 12e₂Is integrally formed with the housing.
