The invention provides a floor type air conditioner indoor unit and an air conditioner comprising the floor type air conditioner indoor unit. The following description describes a floor-type air conditioner indoor unit as a specific embodiment.
Referring to fig. 1, a floor type air conditioner indoor unit 10 includes a housing 11, a heat exchanger, a volute assembly and a wind wheel, wherein the heat exchanger and the volute assembly enclose to form a heat exchange air duct, and the wind wheel is arranged 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. 2, a fresh air component 12 is further installed in the housing 11, the fresh air component 12 has an auxiliary air outlet 120, the fresh air component 12 is configured to introduce outdoor air into a room, and the auxiliary air outlet 120 is located at an outer peripheral side of the main air outlet 110, so that when the main air outlet 110 is air-out, air flow flowing out from the auxiliary air outlet 120 is mixed with air flow flowing out from the main air outlet 110.
The wind wheel in the floor type air conditioner indoor unit 10 may be an axial flow wind wheel, a cross flow wind wheel or a centrifugal wind wheel, which is not limited herein. The outdoor air may be introduced into the room by the fresh air component 12 either actively or passively.
Specifically, a fresh air fan may be disposed in the fresh air component 12, or there may be no fresh air fan.
For the embodiment provided with the fresh air fan 12a (active induced draft), the fresh air fan 12a draws outdoor air into the room when the air conditioner is in operation, so that it can be actively mixed with the air flow blown out by the main air outlet 110.
For the embodiment without a fresh air fan (passive induced air), when the air conditioner is in operation, because the airflow velocity blown out by the main air outlet 110 is larger, a negative pressure area is formed in front of the main air outlet 110, the airflow around the auxiliary air outlet 120 is collected in front of the main air outlet 110, and of course, the auxiliary air outlet 120 also conveys the airflow towards the front of the main air outlet 110 under the influence of the negative pressure. Especially, when the distance between the auxiliary air outlet 120 and the main air outlet 110 is relatively short, the negative pressure air supply effect is better.
Referring to fig. 1, 10-13, there are various situations of the position relationship between the auxiliary air outlet 120 and the main air outlet 110, for example, it is enough that the auxiliary air outlet 120 is located at the upper side of the main air outlet 110, the auxiliary air outlet 120 is located at the lower side of the main air outlet 110, and the auxiliary air outlet 120 is located at the left side or the right side of the main air outlet 110.
The shapes of the main air outlet 110 and the auxiliary air outlet 120 are not limited, and the main air outlet 110 may be substantially square, may be elongated extending vertically, may be bar-shaped extending horizontally, or may be circular.
The auxiliary air outlet 120 may be circular, elongated extending up and down, elongated extending horizontally, arc-shaped, or annular.
The shapes of the main air outlet 110 and the auxiliary air outlet 120 may be combined according to actual requirements.
For example, when the main air outlet 110 is circular, the auxiliary air outlet 120 may be a strip extending vertically, a strip extending horizontally, a ring (surrounding the main air outlet 110), or an arc (below, left, right, or above the main air outlet 110).
When the main air outlet 110 is square, the auxiliary air outlet 120 may be elongated, annular (around the main air outlet 110), arc-shaped (below, left, right or above the main air outlet 110), or U-shaped (below or above the main air outlet 110).
When the main air outlet 110 is disposed in a strip shape extending in an up-down direction, the auxiliary air outlet 120 may be disposed in a strip shape extending in an up-down direction, and disposed in a ring shape (surrounding the main air outlet 110).
According to the technical scheme, the fresh air component 12 is additionally arranged in the floor type air conditioner indoor unit 10, and the fresh air component 12 is used for introducing the external fresh air into the room and mixing the fresh air with the air flow blown out by the main air outlet 110, so that the blown air is fresher on one hand, and the problem of supercooling or overheating of the air flow blown out by the main air outlet 110 is avoided on the other hand.
With continued reference to fig. 1, 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 long, otherwise, the negative pressure formed in front of the main air outlet 110 has little influence on the air outlet of the auxiliary air outlet 120.
In view of this, in the present embodiment, the auxiliary air outlet 120 is disposed adjacent to the main air outlet 110, so that when the main air outlet 110 is air-out, the air flow flowing out from the auxiliary air outlet 120 flows to the front side of the main air outlet 110 under the negative pressure formed at the front side of the main air outlet 110.
For the approach degree of the main air outlet 110 and the auxiliary air outlet 120, the smaller the distance between the main air outlet 110 and the auxiliary air outlet 120 is, the larger the influence of the air flow blown out by the main air outlet 110 on the auxiliary air outlet 120 is, and in order to make the air flow blown out by the auxiliary air outlet 120 larger, the distance between the auxiliary air outlet 120 and the main air outlet 110 is d, and d is less than or equal to 5cm. For example, d=0.1 cm (about the thickness of one separator), 0.5cm, 1cm, 2cm, 2.5cm, 3cm, 3.5cm, 4cm, 4.5cm, etc. are all possible.
In another preferred embodiment, referring to fig. 1, 7 and 10 to 13, the main air outlet 110 and the auxiliary air outlet 120 extend in the vertical direction, and the auxiliary air outlet 120 is located on at least one side of the main air outlet 110 in the width direction.
Here, the main air outlet 110 and the auxiliary air outlet 120 are configured as described above, so that the effective negative pressure influence area of the main air outlet 110 on the auxiliary air outlet 120 can be increased, thereby increasing the air supply amount of the auxiliary air outlet 120. In addition, the disposition of the auxiliary air outlet 120 on at least one side in the width direction of the main air outlet 110 may be understood as: the auxiliary air outlets 120 may be one or two.
For the embodiment in which the number of the auxiliary outlets 120 is two, the two auxiliary outlets 120 are respectively disposed on two opposite sides of the width direction of the main outlet 110. The two auxiliary air outlets 120 are respectively located at two opposite sides of the main air outlet 110, and are disposed oppositely.
With respect to the main air outlet 110, referring to fig. 10, two auxiliary air outlets 120 may be located on opposite sides of the upper portion of the main air outlet 110 and disposed opposite to each other.
Referring to fig. 12, the auxiliary air outlet 120 may be disposed corresponding to the middle of the main air outlet 110, and the auxiliary air outlet 120 may be disposed on two opposite sides of the lower portion of the main air outlet 110.
Referring to fig. 7, the auxiliary air outlets 120 may also be located at two opposite sides of the lower portion of the main air outlet 110, and the two air outlets are disposed opposite to each other.
For the embodiment where the auxiliary air outlet 120 is close to the upper portion of the main air outlet 110, when the floor type indoor unit 10 is in the heating mode (the main air outlet 110 supplies hot air), the air flow blown out from the upper portion of the main air outlet 110 is mixed with outdoor fresh air, and the temperature of the mixed air flow is low, so that the air flow with relatively low temperature presses the hot air flow located below the air flow, so that the hot air flow is blown farther, the indoor heating is easier, and the temperature is more uniform.
For the embodiment where the auxiliary air outlet 120 is close to the lower portion of the main air outlet 110, when the floor type indoor unit 10 is in the cooling mode, the air flow blown out from the lower portion of the main air outlet 110 is mixed with outdoor fresh air, so the temperature of the mixed air flow is higher. Thus, when the main air outlet 110 supplies cold air, the lower part of the air flow blown out by the main air outlet 110 has a higher temperature, so that the cold air flow is not suitable to drop downwards under the condition that the air flow with a higher temperature is supported (the hot air flow is light and easy to rise, the cold air flow is heavy and easy to fall), and the cold air flow can supply more air, so that the indoor refrigeration is easier and the temperature is more uniform. In the cooling mode, in order to make the air flow temperature of the lower portion of the main air outlet 110 higher, so that the cool air is not easy to fall down rapidly, in a preferred embodiment, the length of the auxiliary air outlet 120 is greater than the vertical distance between the upper edge of the auxiliary air outlet 120 and the lower edge of the main air outlet 110. Thus, the air flow blown out from the auxiliary air outlet 120 and the air flow at the lower part of the main air outlet 110 have better mixing effect, and are more beneficial to cold air supply.
Referring to fig. 12, in the embodiment in which the auxiliary air outlet 120 is disposed corresponding to the middle portion of the main air outlet 110, mainly, the air speed of the air supplied from the middle portion of the main air outlet 110 is the greatest, and the negative pressure formed directly in front of the air outlet is the strongest, so that the mixing of the outdoor fresh air and the air flow blown out from the main air outlet 110 is facilitated.
Referring to fig. 11, in order to further fully mix the air flow blown out from the main air outlet 110 with the air flow blown out from the auxiliary air outlet 120, in this embodiment, the length of the auxiliary air outlet 120 in the up-down direction is L 1, and the length of the main air outlet 110 in the up-down direction is L 2,0.5≤L1/L2 less than or equal to 1.2. That is, the auxiliary air outlet 120 is relatively long in the up-down direction. Thus, when the main air outlet 110 is used for blowing air, more than half of the air flow blown out by the main air outlet 110 can affect the air flow blown out by the auxiliary air outlet 120, so that the air flow blown out by the whole main air outlet 110 and the outdoor fresh air are better in mixing effect, moderate in temperature and more comfortable in user experience.
In the above embodiment, referring to fig. 13, in order to increase the air supply amount of the auxiliary air outlet 120, two main air outlets 110 may be provided (i.e., the floor type indoor unit 10 may be a dual-through-flow indoor unit, two through-flow wind wheels extending vertically are provided in the dual-through-flow indoor unit, two main air outlets 110 corresponding to the two through-flow wind wheels are provided on the housing), the auxiliary air outlet 120 is provided between the two main air outlets 110, and the two main air outlets 110 supply air simultaneously, so that a strong negative pressure is formed in front of the auxiliary air outlet 120, and more air flows from the outside to the inside under the negative pressure and is mixed with the air flow blown out by the main air outlets 110.
Referring to fig. 4, 5 and 6, considering that the air supply amount is low when the auxiliary air outlet 120 adopts the passive mode for supplying air, in this embodiment, the fresh air assembly 12 includes a fresh air fan 12a and an air guiding assembly 12b, the fresh air fan 12a is communicated with the air guiding assembly 12b, the auxiliary air outlet 120 is disposed in the air guiding assembly 12b, and the air inlet of the fresh air fan 12a is communicated with the outside.
Here, the fresh air fan 12a may be a cross flow fan, an axial flow fan or a centrifugal fan, and the outdoor air flow is sucked into the air guide assembly 12b through the fresh air fan 12a and then discharged from the air guide assembly 12b, and the discharged air flow is collected toward the front of the main air outlet 110 under the negative pressure.
Here, the air guiding assembly 12b is substantially in a U-shaped structure, the air guiding assembly 12b includes a switching portion 122 and two air outlet portions 121 (two arms of the U-shaped structure) connected to the switching portion 122, the switching portion 122 is disposed below the main air outlet 110, the two air outlet portions 121 are disposed on opposite sides of the main air outlet 110, the two air outlet portions 121 are respectively communicated with the switching portion 122, the switching portion 122 is communicated with the fresh air fan 12a, and the auxiliary air outlet 120 is correspondingly disposed on the two air outlet portions 121.
Since the auxiliary air outlet 120 is formed on the front side of the air outlet portion 121, a through hole is formed in the bottom of the air outlet portion 121 and is communicated with the adapter portion 122, fresh air pumped outdoors by the fresh air fan 12a flows into the air outlet portion 121 from bottom to top, when the air flow in the air outlet portion 121 is more, under the action of air pressure, the air flow flows out from the auxiliary air outlet 120, and in addition, under the action of negative pressure on the front side of the main air outlet 110, the fresh air is rapidly mixed with the air flow of the main air outlet 110.
In order to better mix the fresh air with the outdoor air, in this embodiment, referring to fig. 14, the main air outlet 110 extends vertically, a plurality of auxiliary air outlets 120 are respectively disposed on two sides of the main air outlet 110 in the width direction, and a plurality of auxiliary air outlets 120 disposed on the same side of the main air outlet 110 are disposed at intervals in the vertical direction.
Thus, when the main air outlet 110 is blowing, the air flows from the plurality of auxiliary air outlets 120 can be mixed with the air flows from the main air outlet 110, and when the hot air is blown, the air flows from the final air conditioner are alternated from top to bottom, for example, the temperature of the air flows from the main air outlet 110 is 25 ℃, the temperature of the air flows from the auxiliary air outlet 120 is 10 ℃, the temperature of the mixed air flows is 20 ℃, and then the temperature of the air flows in front of the main air outlet 110 of the air conditioner is about 25 ℃, 20 ℃, 25 ℃, 20 ℃ and more comfortable for the user from top to bottom.
Because the fresh air is blown out by the air outlet part, if the fresh air enters from the lower end of the air outlet part, the air outlet effect of the auxiliary air outlet 120 close to the lower part of the air outlet part 121 is better, and the air outlet 120 far away from the lower end of the air outlet part 121 may have smaller air supply quantity, or even basically does not supply air. In view of this, in this embodiment, the fresh air assembly 12 includes two air outlet portions 121 disposed on opposite sides of the heat exchange air duct, each air outlet portion 121 is provided with a plurality of auxiliary air outlets 120 arranged along an up-down direction at intervals, each air outlet portion 121 is internally formed with a plurality of mutually isolated sub air ducts (not shown), one end of each sub air duct is communicated with the outside, and the other end of each sub air duct is correspondingly communicated with each auxiliary air outlet 120. That is, the air outlet portion 121 is internally provided with a plurality of mutually isolated sub-air ducts, which may be separately communicated with the outside (may be that air flow is led into each sub-air duct from the outside through a fan), or may be jointly communicated with the outside through an air guiding portion, thereby avoiding the problem of air robbing.
In the above embodiments, the fresh air component 12 is in communication with the outside, and in this embodiment, referring to fig. 2, 7, 8 and 9, the fresh air component 12 may also be in communication with the inside. Specifically, the fresh air component 12 further includes an air guiding portion 12c, the fresh air fan 12a is located between the air guiding portion 12c and the air guiding component 12b, the air guiding portion 12c is communicated with the fresh air fan 12a, a fresh air inlet (not labeled in the drawing) and an indoor air inlet (not labeled in the drawing) are disposed on the air guiding portion 12c, the fresh air inlet is communicated with the outside, the indoor air inlet is communicated with the inside, an air door 12f is disposed on the air guiding portion 12c, and the air door 12f can selectively close the fresh air inlet and the indoor air inlet.
For users, the fresh air is mainly introduced to make the indoor air fresher, but if the quality of the external air is bad, or the temperature of the external air is too high, the users may not need the fresh air all the time, and when appropriate, the indoor air can be introduced into the fresh air component 12, so that the indoor air can flow out from the auxiliary air outlet 120 and be mixed with the air flow flowing out from the main air outlet 110, and the air flow temperature is also prevented from being too low, so that the user is stimulated. In this embodiment, the indoor air inlet and the air door 12f are additionally arranged on the fresh air component 12, and the fresh air component 12 can selectively introduce external air or indoor air through switching of the air door 12 f. Of course, considering that the air quality in the city is low, in a preferred embodiment, a filter assembly 12d is further disposed in the air guiding portion 12c, and the filter assembly 12d may be a Hape mesh, a wet film, a formaldehyde removing mesh, or the like.
