Description

[0002] An air conditioner is a kind of household appliance. The indoor unit of the air conditioner sucks the indoor air from its air inlet through a negative pressure device, exchanges heat through a heat exchange device, and then discharges it into the indoor environment from the air outlet to achieve the purpose of adjusting the temperature of the indoor environment. The heat exchanger of the built-in air conditioner indoor unit in the related art includes two parts opposite in the front-rear direction. Since the front part of the heat exchanger is closer to the air inlet of the indoor unit than the rear part, most of the air flow entering the indoor unit from the air inlet can only pass through the front part of the heat exchanger, and only a small part of the air flow or even no air flow passes through the rear part of the heat exchanger, resulting in less or no heat exchange in the rear part of the heat exchanger away from the indoor unit, and causing the problem of low overall heat exchange efficiency of the heat exchanger. Summary of the Utility Model

[0013] The housing further includes a first air inlet grille and a second air inlet grille. Both the first air inlet grille and the second air inlet grille are arranged at the air inlet. Both the first air inlet grille and the second air inlet grille are plural. The first air inlet grilles are all closer to the top wall surface of the installation cavity than the second air inlet grilles.

[0037] The air conditioner indoor unit 100 of the embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0038] As Figures 1 - 5 shown, the air conditioner indoor unit 100 of the embodiment of the present utility model includes a housing 1 and a heat exchanger 2.

[0039] The housing 1 defines an installation cavity 10, and the housing 1 has a front panel 11. The heat exchanger 2 is disposed in the installation cavity 10, and the heat exchanger 2 includes a first part 21 and a second part 22. The first part 21 is laterally farther from the front panel 11 than the second part 22.

[0040] The front panel 11 has a first air inlet gap 1101 and a second air inlet gap 1102. The first air inlet gap 1101 is closer to the top wall surface 103 of the installation cavity 10 than the second air inlet gap 1102. The installation cavity 10 includes a first air inlet area 101 and a second air inlet area 102 that are opposite in the vertical direction, and the first air inlet area 101 is closer to the top wall surface 103 of the installation cavity 10 than the second air inlet area 102.

[0041] At least part of the first part 21 is located in the first air inlet area 101, at least part of the second part 22 is located in the second air inlet area 102. The first air inlet gap 1101 corresponds to the first air inlet area 101, the second air inlet gap 1102 corresponds to the second air inlet area 102, and the size of the first air inlet gap 1101 is larger than the size of the first air inlet gap 1101.

[0042] In other words, a part of the outside air enters the first air inlet area 101 through the first air inlet gap 1101. After passing through the first air inlet area 101, this part of the air passes through the first part 21 of the heat exchanger 2, thereby exchanging heat with the first part 21 of the heat exchanger 2. Another part of the outside air enters the second air inlet area 102 through the second air inlet gap 1102. After passing through the second air inlet area 102, this other part of the air passes through the second part 22 of the heat exchanger 2, thereby exchanging heat with the second part 22 of the heat exchanger 2.

[0043] Compared with the related art, in the air conditioner indoor unit 100 according to the embodiment of the present invention, the size of the first air inlet gap 1101 corresponding to the first air inlet area 101 is larger than the size of the second air inlet gap 1102 corresponding to the second air inlet area 102, so that the air flow velocity passing through the second air inlet gap 1102 is smaller, and the air flow velocity passing through the first air inlet gap 1101 is larger. Thereby increasing the air intake of the first air inlet area 101, enabling more air to pass through the first part 21 and exchange heat with the first part 21, and thus improving the overall heat exchange efficiency of the heat exchanger 2.

[0044] To make the present application easier to understand, hereinafter, taking the vertical direction being consistent with the up-and-down direction and the horizontal direction being consistent with the front-and-back direction as examples, the air conditioner indoor unit 100 according to the embodiment of the present invention will be further described.

[0045] As Figures 1 - 5 shown, the air conditioner indoor unit 100 according to the embodiment of the present invention includes a housing 1, a heat exchanger 2, and a blower fan 3.

[0046] The housing 1 defines an installation cavity 10. The installation cavity 10 includes a first air inlet area 101 and a second air inlet area 102 that are opposite in the up-and-down direction. The first air inlet area 101 is located above the second air inlet area 102. The housing 1 includes a front panel 11. The front panel 11 has a first air inlet gap 1101 and a second air inlet gap 1102. The first air inlet gap 1101 corresponds to the first air inlet area 101, and the second air inlet gap 1102 corresponds to the second air inlet area 102. Both the heat exchanger 2 and the blower fan 3 are provided in the installation cavity 10. The blower fan 3 is used to promote the formation of an air flow that enters the installation cavity 10 from the first air inlet gap 1101 and the second air inlet gap 1102 and passes through the heat exchanger 2. The heat exchanger 2 is used to exchange heat with this air flow, and the heat-exchanged air flow is discharged into the indoor area.

[0047] The air conditioner indoor unit 100 of this embodiment is an embedded air conditioner indoor unit 100, configured to be embedded and installed in an installation groove 201 that accommodates the indoor unit body. Among them, the installation groove 201 can be formed on the cabinet 200; or, on the wall of the indoor area, that is, the air conditioner indoor unit 100 is embedded in the cabinet or the wall of the room.

[0048] The embedded air conditioner indoor unit 100 is embedded in a cabinet or an indoor wall, which can hide the air conditioner indoor unit 100 in appearance, making the home layout more beautiful and thus improving the user experience. For example Figure 5 As shown, the air conditioner indoor unit 100 of this embodiment is embedded in the cabinet 200.

[0049] In some embodiments, such as Figure 5 As shown, both the first air inlet gap 1101 and the second air inlet gap 1102 correspond to the open opening 202, so that the first air inlet gap 1101 and the second air inlet gap 1102 avoid the wall surface of the installation groove 201, enabling the air conditioner indoor unit 100 to intake air smoothly.

[0050] In some embodiments, such as Figure 1 and Figure 2 As shown, the opening direction of the first air inlet gap 1101 is consistent with the front-back direction. In other words, when the air flow passes through the first air inlet gap 1101, the first air inlet gap 1101 has a guiding effect on the air flow, and the air flow is guided by the first air inlet gap 1101 to flow in the front-to-back direction, so that it is easier to flow to the rear end of the first air inlet area 101, ensuring that more air can exchange heat with the first part 21 of the heat exchanger 2. Therefore, the overall heat exchange efficiency of the heat exchanger 2 is further improved.

[0051] In other embodiments, the opening direction of the first air inlet gap 1101 opens upward in the direction extending toward the inside of the installation cavity 10, that is to say, the opening direction of the first air inlet gap 1101 is rearward and upward. In other words, when the air flow passes through the first air inlet gap 1101, the air flow is guided by the first air inlet gap 1101 to flow in the rearward and upward direction, avoiding flowing downward in advance and exchanging heat with the second part 22 of the heat exchanger 2 when the air flow passes through the second part 22 of the heat exchanger 2, ensuring that more air can exchange heat with the first part 21 of the heat exchanger 2. Therefore, the overall heat exchange efficiency of the heat exchanger 2 is further improved.

[0052] In some embodiments, such as Figures 1 - 2 As shown, there are multiple first air inlet gaps 1101, and the multiple first air inlet gaps 1101 are spaced apart in the up-down direction, and the multiple first air inlet gaps 1101 all correspond to the first air inlet area 101. There are multiple second air inlet gaps 1102, and the multiple second air inlet gaps 1102 are spaced apart in the up-down direction, and the multiple second air inlet gaps 1102 all correspond to the second air inlet area 102.

[0053] The front panel 11 has multiple first air inlet gaps 1101 and multiple second air inlet gaps 1102, which not only ensure a large air intake volume of the air conditioner indoor unit 100, but also make the air intake of the air conditioner indoor unit 100 more uniform in the up-down direction.

[0054] Specifically, the front panel 11 has an air inlet, and the air inlet communicates with the installation cavity 10. The housing 1 further includes a first air inlet grille 12 and a second air inlet grille 13, and both the first air inlet grille 12 and the second air inlet grille 13 are provided at the air inlet. Both the first air inlet grille 12 and the second air inlet grille 13 are plural, and the first air inlet grille 12 is adjacent to the top wall surface 103 of the installation cavity 10 relative to the second air inlet grille 13.

[0055] The plural first air inlet grilles 12 are spaced apart in the vertical direction, and a first air inlet gap 1101 is formed between adjacent first air inlet grilles 12. The plural second air inlet grilles 13 are spaced apart in the vertical direction, and a second air inlet gap 1102 is formed between adjacent second air inlet grilles 13. Among them, the spacing distance between adjacent first air inlet grilles 12 in the vertical direction is greater than the spacing distance between adjacent second air inlet grilles 13 in the vertical direction.

[0056] In other words, by using the plural first air inlet grilles 12 to form the first air inlet gaps 1101 spaced apart in the vertical direction at the air inlet, and using the plural second air inlet grilles 13 to form the second air inlet gaps 1102 spaced apart in the vertical direction at the air inlet, not only can a plurality of first air inlet gaps 1101 and second air inlet gaps 1102 be formed at the air inlet, but also the structure is simple and easy to manufacture.

[0057] In some other embodiments, a plate body (not shown in the figure) is provided at the air inlet. The plate body is provided with a first air-permeable opening and a second air-permeable opening. Both the first air-permeable opening and the second air-permeable opening are plural, and the first air-permeable opening is located above the second air-permeable opening. The aperture of the first air-permeable opening is larger than that of the second air-permeable opening. That is to say, the first air-permeable opening forms the first air inlet gap 1101, and the second air-permeable opening forms the second air inlet gap 1102.

[0058] In some embodiments, as Figures 1 - 4 shown, the second part 22 includes a first section 221 and a second section 222 connected in sequence in the vertical direction. The first section 221 is farther from the top wall surface 103 of the installation cavity 10 relative to the second section 222, and the extending direction of the first section 221 is consistent with the vertical direction.

[0059] The second section 222 is inclined. The end of the second section 222 adjacent to the first part 21 is closer to the top wall surface 103 of the installation cavity 10 than the other end. That is to say, the rear end of the second section 222 is located above its front end. The rear end of the second section 222 is connected to the first part 21, and the front end of the second section 222 is connected to the first section 221. The first part 21 and the second part 22 of the heat exchanger 2 surround the upper part of the air supply fan 3. That is to say, the heat exchanger 2 is adapted to the air supply fan 3, so that the air flow formed by the air supply fan 3 passes through the first part 21 and the second part 22 more evenly, thereby improving the overall heat exchange efficiency of the heat exchanger 2.

[0060] The size of the second air inlet gap 1102 corresponding to the first section 221 in the vertical direction is smaller than the size of the second air inlet gap 1102 corresponding to the second section 222 in the vertical direction. Further reducing the size of the second air inlet gap 1102 corresponding to the first section 221 further reduces the flow velocity of the air flow passing through the second air inlet gap 1102 corresponding to the first section 221, thereby preventing noise generated by the excessively high flow velocity of this part of the air flow when passing through the heat exchanger 2, and thus improving the user experience.

[0061] Specifically, the front panel 11 includes two groups of second air inlet gaps 1102. The two groups of second air inlet gaps 1102 are spaced apart in the vertical direction. Each group of second air inlet gaps 1102 includes a plurality of second air inlet gaps 1102. The plurality of second air inlet gaps 1102 in the upper group of second air inlet gaps 1102 correspond to the first section 221, and the plurality of second air inlet gaps 1102 in the lower group of second air inlet gaps 1102 correspond to the second section 222.

[0062] In some embodiments, as Figures 1 - 4 shown, the extending direction of the first air inlet grille 12 is consistent with the front-rear direction. In other words, when the air flow passes through the first air inlet gap 1101 between adjacent first air inlet grilles 12, the first air inlet grille 12 has a guiding effect on the air flow, and the air flow is guided by the first air inlet grille 12 to flow in the direction from front to back, so that it is easier to flow to the rear end of the first air inlet area 101, ensuring that more air can exchange heat with the first part 21 of the heat exchanger 2, and thus further improving the overall heat exchange efficiency of the heat exchanger 2.

[0063] In some embodiments, as Figures 1 - 4 shown, the second air inlet grille 13 is inclined, and the end of the second air inlet grille 13 adjacent to the second part 22 is farther from the top wall surface 103 of the installation cavity 10 than the other end. In other words, when the air flow passes through the second air inlet gap 1102 between adjacent second air inlet grilles 13, the second air inlet grille 13 has a guiding effect on the air flow, and the air flow is guided by the second air inlet grille 13 to flow in the direction of the back and down, so that the air flow passing through the second air inlet gap 1102 can flow more smoothly to the second part 22 of the heat exchanger 2, and thus the heat exchange efficiency of the first part 21 of the heat exchanger 2 is improved.

[0064] The air conditioner according to an embodiment of the present utility model includes the air conditioner indoor unit 100 of any one of the above embodiments. The air conditioner indoor unit 100 of the air conditioner according to an embodiment of the present utility model has a first air inlet gap 1101 corresponding to the first air inlet area 101 that is larger than a second air inlet gap 1102 corresponding to the second air inlet area 102, so that the air flow velocity through the second air inlet gap 1102 is smaller, and the air flow velocity through the first air inlet gap 1101 is larger. As a result, the air intake volume of the first air inlet area 101 increases, enabling more air to pass through the first part 21 and exchange heat with the first part 21, thus improving the overall heat exchange efficiency of the heat exchanger 2.

[0065] At this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present utility model have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present utility model can still be directly determined or derived based on the content disclosed in the present utility model without departing from the spirit and scope of the present utility model. Therefore, the scope of the present utility model should be understood and recognized as covering all these other variations or modifications.
