The invention provides an air conditioner indoor unit and an air conditioner comprising the same. Regarding the indoor unit of the air conditioner, the following description is given with reference to specific embodiments of the indoor unit of the suspended ceiling type.

Referring to fig. 1 and 3, the indoor unit 10 has a housing 11, a wind wheel 12, a heat exchanger 13, a water pan 14, and a scroll housing assembly 15. The housing 11 includes a front panel 11a, a rear panel 11b, a left side panel (not shown), a right side panel (not shown), and a top panel 11c, and the front panel 11a is provided with an air outlet 110. The water receiving tray 14 is located in the housing 11, and the water receiving tray 14 covers the lower port of the housing 11 (the water receiving tray 14 is connected with four walls of the housing 11), and the water receiving tray 14 is located below the heat exchanger 13 and is used for receiving condensed water formed on the surface of the heat exchanger 13. The volute assembly 15 is formed with an air outlet duct that communicates with the air outlet 110. The first air deflector 16 is installed at the air outlet 110, so that the air outlet angle can be adjusted. The panel is also provided with a second air deflector 17, the second air deflector 17 can rotate to further adjust the air outlet angle, and on the other hand, when the air conditioner stops running, the second air deflector 17 can cover the air outlet 110 to prevent dust or other sundries from entering.

The heat exchanger 13 may be a two-fold heat exchanger, a three-fold heat exchanger, or a flat plate heat exchanger. The heat exchanger 13 may be V-shaped (two-fold heat exchanger 13) or substantially U-shaped (three-fold heat exchanger).

Referring to fig. 3 and 4, the water tray 14 has a tray bottom 14a, the tray bottom 14a is provided with a blocking portion 14b (protruding from the upper surface of the tray bottom 14 a), and the blocking portion 14b is laterally provided with an air passing gap 144. The air passing gap 144 may be provided on the front side and/or the rear side of the blocking portion 14b, or may be provided on the left end side and/or the right end side of the blocking portion 14 b. The following will describe the case where the air passing gap 144 is provided at the front side and/or the rear side of the blocking portion 14 b. The bottom of the blocking portion 14b is provided with a through hole 145 penetrating the tray bottom 14a and communicating with the air passing gap 144.

The water receiving tray 14 includes, in addition to the tray bottom 14a, coamings (not shown) attached to both sides of the tray bottom 14a, and end plates (not shown) provided at both ends of the tray bottom 14 a. The end plates, the coamings and the tray bottom 14a together form the basic structure of the water tray 14. The number of the air passing gaps 144 formed in the lateral direction of the blocking portion 14b may be plural, or may be plural, and for the embodiment of the air passing gaps 144, the air passing gaps 144 are arranged at intervals in the length direction of the blocking portion 14 b.

The blocking portions 14b may be arranged at intervals in the longitudinal direction (left-right direction in the drawing) of the tray bottom 14 a. Of course, in order to fit the installation of the heat exchanger 13 and also to reduce the manufacturing cost, the blocking portion 14b is preferably provided to extend continuously (without interval) in the longitudinal direction of the tray bottom 14a, and both ends thereof are directly connected to both end plates. The barrier 14b allows on the one hand the external air flow to pass through and on the other hand also supports the heat exchanger 13.

According to the technical scheme of the invention, the blocking part 14b is convexly arranged on the tray bottom 14a of the water tray 14, the air passing gap 144 is laterally formed in the blocking part 14b, and the through hole 145 penetrating the tray bottom 14a and communicated with the air passing gap 144 is formed in the bottom of the blocking part 14b, so that the water tray 14 can not only receive condensed water formed on the surface of the heat exchanger 13, but also allow outside air to pass through, thereby reducing the wind resistance of the outside air entering the air conditioner indoor unit 10, improving the air output and energy efficiency, further improving the air supply distance of the air conditioner indoor unit 10, and improving the foot warming effect.

The above embodiment does not limit the structure of the heat exchanger 13. In view of the fact that the two-fold and three-fold heat exchangers are disadvantageous for the overall height of the air conditioning indoor unit 10 to be thinned, in the present embodiment, the heat exchanger 13 extends from the front panel 11a toward the rear panel. That is, the heat exchanger 13 is arranged in a flat plate shape, for the heat exchanger 13, referring to fig. 2, an included angle α e [0, 30 ° ] with respect to a horizontal plane, α=0 °, 5 °, 10 °, 15 °, 25 °, 30 ° is all possible. For example, the heat exchanger 13 is disposed obliquely rearward with an angle of inclination α.

Of course, if α=0°, the thinning of the air conditioning indoor unit 10 is most favorable. In addition, in order to make the contact area of the heat exchanger 13 with air larger, α may be appropriately adjusted to be large, for example, α=5°,7 ° or 10 °.

In the above embodiment, the extending direction of the blocking portion 14b is not limited, that is, the blocking portion 14b may be disposed at will on the tray bottom 14a, for example, may be parallel or intersecting.

Referring to fig. 3, 5 and 7, in order to make the air intake more uniform, the air volume greater, and the die sinking of the water tray 14 easier, the cost is lower, in this embodiment, the housing 11 has a first side plate and a second side plate opposite to each other, and the blocking portion 14b extends from the first side plate toward the second side plate.

Here, the first side plate and the second side plate may refer to the front panel 11a and the rear panel 11b, or may refer to the left side plate and the right side plate, respectively. The barriers 14b are arranged substantially parallel to each other (allowing for a certain small angle, e.g. 1 deg. to 10 deg.), although it is optimal that the barriers 14b are parallel to each other.

On the basis of the above embodiment, if the first side plate and the second side plate refer to the front panel 11a and the rear panel 11b, the through hole 145 at the bottom of the blocking portion 14b extends in the front-rear direction, so that a serious air return phenomenon occurs when the indoor unit 10 operates.

In view of this, referring to fig. 1,3, 4, 5,6, 7, 8 and 9, in the present embodiment, the first side plate connects the front panel 11a and the rear panel 11b, and the second side plate connects the front panel 11a and the rear panel 11b. That is, the through hole 145 at the bottom of the blocking portion 14b extends in the left-right direction. Thus, when the indoor unit 10 of the air conditioner is operated, the wind wheel 12 sucks in the outside air from the through hole 145, and the air located on the front panel 11a or the air current just blown out from the air outlet 110 is difficult to suck into the through hole 145 due to the blocking effect of the blocking portion 14 b.

The following will specifically describe the specific structure of the preferred embodiment of the barrier portion 14 b.

In an embodiment, referring to fig. 4, 6 and 8, the blocking portion 14b includes two water blocking plates 141 and 142 extending along the direction of the first side plate toward the second side plate, and a cover plate 143 extending along the direction of the first side plate toward the second side plate, the cover plate 143 is located above the two water blocking plates 141 and 142, and the air passing gap 144 is formed between the water blocking plates 141 and 142 and at least one side of the cover plate 143; the through holes 145 are provided on the tray bottom 14a corresponding to the two water stop plates 141, 412.

There are various ways of mounting the heat exchanger 13 within the housing 11, for example, the heat exchanger 13 may be connected to a side wall or a top wall of the housing 11.

To facilitate the installation of the heat exchanger 13 and also to facilitate the cleaning of the heat exchanger 13, in a preferred embodiment, referring to fig. 1 and 3, the upper surface of the cover 143 abuts the heat exchanger 13. That is, the entire heat exchanger 13 may be carried on the drip tray 14. When the air conditioner indoor unit 10 is assembled, the wind wheel 12 and the volute assembly 15 can be firstly installed in the shell 11, then the heat exchanger 13 is installed on the water receiving disc 14, and finally the water receiving disc 14 and the heat exchanger 13 are installed in the shell 11 together. If the inside of the shell 11 is dirty due to long-time uncleanness, when the air duct is dirty, the inner structure needs to be cleaned, the water pan 14 can be conveniently detached, then the water pan 14 and the heat exchanger 13 are cleaned, and the volute component 15 or the wind wheel 12 can be cleaned, so that the cleaning is very convenient and quick.

Further, in order to make the installation of the heat exchanger 13 on the water tray 14 more secure, the heat exchanger 13 and the end tray may be provided as a detachable connection.

The cover plate 143 may support the heat exchanger 13, or may not support the heat exchanger 13, and it should be noted that another main function of the cover plate 143 is to have a diversion effect on the water flow dropped on the water tray 14, so as to avoid water leakage.

In order to make the water blocking effect of the cover plate 143 better, in the embodiment, referring to fig. 4, the projection width of the cover plate 143 on the horizontal plane is d1, and the projection distance of the upper ends of two adjacent water blocking plates 141 of the same blocking portion 14b on the horizontal plane is d2, where d2 is less than or equal to d1. In this way, when the condensed water falls down onto the cover plate 143, the condensed water can flow from both sides of the cover plate 143 to both sides of the blocking portion 14b, so that the condensed water can be prevented from leaking out of the through hole 145.

On one hand, the shielding area of the cover plate 143 on the heat exchanger 13 is considered to be larger, so that the heat exchange efficiency of the heat exchanger 13 can be reduced; on the other hand, when the condensed water falls down to the upper surface of the cover plate 143, the condensed water may flow to the lower surface of the cover plate 143, so that the condensed water drops from the through holes 145, and a water leakage phenomenon occurs, thus seriously affecting the user experience.

In view of the above two problems, in the present embodiment, referring to fig. 9, 10a to 10d, and 11a to 11d, at least a portion of the upper end of the cover 143 is tapered from bottom to top. In this way, the direct coverage area of the cover plate 143 to the heat exchanger 13 is reduced, and the effective area of the heat exchanger 13 in contact with air is increased after the air enters the heat exchanger 13. Meanwhile, when the condensed water drops to the cover plate 143, due to such tapered arrangement of the upper end of the cover plate 143, the condensed water rapidly flows down along the upper surface of the cover plate 143, and it is difficult to form water drops on the lower surface of the cover plate 143.

The embodiments in which the upper end of the cover plate 143 is tapered are various, for example, the upper end of the cover plate 143 is arc-shaped, trapezoidal, inverted V-shaped, etc.

After the condensed water gathers in the water receiving disc 14, the temperature of the disc bottom 14a of the water receiving disc 14 is very low due to the low temperature, so that the disc bottom 14a of the water receiving disc 14 is easy to generate condensation, and the user experience is seriously affected after the condensation drops.

In a preferred embodiment, the housing 11 further includes a bottom plate (not shown), and the water pan 14 is mounted on an upper surface of the bottom plate, and an air inlet hole communicating with the through hole 145 is formed in the bottom plate. The bottom 14a of the water tray 14 has a certain thickness, and the thickness of the bottom plate can greatly slow down the formation of condensation. The arrangement of the base plate has a certain supporting and protective effect on the drip tray 14. Here, the base plate may be a metal plate based on the overall structural strength of the air conditioning indoor unit 10; the bottom plate may be a plastic plate based on avoiding condensation formation, and of course, the bottom plate may also be a heat insulating material plate directly.

On the basis of the above embodiment, in order to further enhance the effect of isolating the tray bottom 14a from the outside air, a heat insulating layer is provided between the water tray 14 and the bottom plate in this embodiment. For example, a foam layer, and for example, a rubber layer. Here, after the rubber layer is provided, the rubber layer is tightly abutted against the tray bottom 14a of the water tray 14, and air can be prevented from entering between the rubber layer and the tray bottom 14a, so that the anti-condensation effect is better.

In the above embodiment, the cover plate 143 may or may not support the water tray 14. If all of the cover plates 143 are abutted against the heat exchanger 13, the heat exchanging area of the heat exchanger 13 will be reduced. If all of the cover plates 143 are not abutted against the heat exchanger 13, the stability of the installation of the heat exchanger 13 will be affected.

In view of this, referring to fig. 9, 10a to 10d and 11a to 11d, in the present embodiment, the cover plate 143 includes two types of cover plates 143, i.e. a first type cover plate 143a and a second type cover plate 143b, the first type cover plate 143a and the second type cover plate 143b143 are alternately arranged, and the second type cover plate 143b143 is connected to the bottom plate or tray 14a through a support column 146. Thus, the partial cover plate 143 is abutted with the heat exchanger 13, the partial cover plate 143 is spaced from the heat exchanger 13 (the second type cover plate 143b143 is abutted with the heat exchanger 13, and the first type cover plate 143a is spaced from the heat exchanger 13), so that on one hand, the installation stability of the heat exchanger 13 is ensured, and on the other hand, the heat exchange area of the heat exchanger 13 is not excessively affected.

On the basis of the above embodiment, referring to fig. 9, 10a to 10d and 11a to 11d, in order to further reduce the area of the cover plate 143 covering the heat exchanger 13, in this embodiment, the upper end of the second type cover plate 143b is tapered from bottom to top.

Here, the tapered arrangement of the second type of cover plate 143b reduces the direct shielding area of the cover plate 143 to the heat exchanger 13, and increases the effective area of the heat exchanger 13 in contact with air after the air enters the heat exchanger 13. Meanwhile, when the condensed water falls down to the cover plate 143, the condensed water rapidly flows down along the upper surface of the cover plate 143, and it is difficult to form water drops on the lower surface of the cover plate 143.

There are various embodiments in which the upper end of the second type cover plate 143b is tapered, for example, the upper end of the second type cover plate 143 is arc-shaped (as shown in fig. 11 d), trapezoid-shaped (as shown in fig. 11 c), inverted V-shaped (as shown in fig. 11 b), etc.

Referring to fig. 5 to 8, in another preferred embodiment of the blocking portion 14b, two water-stop plates 141 of the blocking portion 14b extend obliquely upward, and the oblique directions of the two water-stop plates 141, 142 are opposite, wherein an upper end of one water-stop plate 141 is higher than the other water-stop plate 142, and the cover 143 is connected to the water-stop plate 141 with a higher upper end.

Such inclined extension of the water stop plate 141 can prevent the condensed water from dripping to the upper surface of the tray bottom 14a to cause the phenomenon of splash of water droplets.

Referring to fig. 8, in the above embodiment, when condensed water is collected between two adjacent blocking portions 14b, since the water-stop plate 142 of one blocking portion 14b is lower than the water-stop plate 141 of the other blocking portion 14b, once the amount of condensed water is large, the condensed water overflows from the water-stop plate 142 with the lower upper end.

In view of this, in the present embodiment, in order to increase the water receiving amount of the water receiving tray 14, the upper surface of the water blocking plate 141 having a higher upper end position is provided with water blocking ribs 146 extending in the direction of the first side plate toward the second side plate. After the water retaining ribs 146 are arranged, part of condensed water can be gathered in the water tank formed between the water retaining ribs 146 and the water stop plate 141, so that the water receiving amount of the water receiving disc is greatly increased.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
