Description

Technical Field

[0001] The present application relates to but is not limited to the field of air conditioning technology, and specifically refers to an embedded air conditioner indoor unit and an air conditioner. Background Art

[0002] The current embedded X-space (including kitchen, bathroom, cloakroom, entrance, etc.) air conditioner indoor units on the market usually adopt the structural layout of fuselage + panel. Among them, the indoor heat exchanger and water tray are located completely on the upper part of the panel, resulting in an increase in the height of the fuselage. The floor height of the X-space is slightly lower than that of the horizontal and living room. Taking the kitchen as an example, 13.5% of the kitchen ceiling heights are lower than 2.3m, which is lower than the human comfort height of 2.4m. The height of the X-space air conditioner indoor unit determines the height of the ceiling. Therefore, after the installation of the embedded X-space air conditioner indoor unit on the current market, some ceilings give people a sense of depression, affecting the user experience.

[0051] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0052] Figure 1-Figure 2 1 is a structural diagram of an air conditioner indoor unit 100 of the prior art. Figure 3-Figure 10 Schematic diagram of the structure of an embedded air conditioner indoor unit 200 according to some exemplary embodiments of the present application.

[0053] like Figure 1-Figure 2As shown, the air conditioner indoor unit 100 of the prior art includes a body 1 and a panel 2. The airflow enters the inner cavity of the air conditioner indoor unit 100 from the return air port 23, passes through the indoor heat exchanger 17 for heat exchange, and flows out from the air outlet 22. The indoor heat exchanger 17 can be set as a finned heat exchanger. After the indoor heat exchanger 17 exchanges heat with the airflow, water droplets will condense on the surface of the indoor heat exchanger 17, and the water droplets will fall into the water receiving tray 12. In the air conditioner indoor unit 100 of the prior art, the water receiving tray 12 is arranged above the panel 2, the indoor heat exchanger 17 is arranged above the water receiving tray 12, and the electric control box 13 is located inside the panel 2. In the air conditioner indoor unit 100 of the prior art, the water receiving tray 12 and the indoor heat exchanger 17 are both arranged above the panel 2, so that the height of the body 1 is relatively high; the electric control box 13 is arranged inside the panel 2. In order to meet the requirements of the electric control layout, the thickness of the panel 2 must be increased, resulting in a large height of the whole machine and a problem of limited installation.

[0054] like Figure 2 As shown, in the prior art air conditioner indoor unit 100, a first driving mechanism 51 is arranged on one side of the air guide plate 52 at the air outlet 22. The first driving mechanism 51 may be a motor. The air guide plate 52 does not cover the position corresponding to the motor. The air guide plate 52 is arranged on one side to leave space for the motor. Figure 1 As shown, in the prior art air conditioner indoor unit 100, the air duct wall shape design of the air outlet duct 3 is limited by the shape of the casing, and is set in the form of a combination of a straight air duct wall and an arc-shaped air duct wall. In the prior art air conditioner indoor unit 100, a plurality of parallel air supply grilles are set at the return air outlet 23, so that the return air outlet 23 cannot be completely closed and covered.

[0055] like Figure 3-Figure 6 As shown, the embodiment of the present application provides an embedded air conditioner indoor unit 200, including a body 1 and a panel 2. The body 1 includes a casing 11 and a water receiving tray 12, the upper part of which is fixed in the casing 11; the panel 2 is fixed to the lower side of the body 1, and the panel 2 is provided with an installation cavity 21 with an opening facing upward, and the bottom of the water receiving tray 12 protrudes from the lower end surface 112 of the casing 11 and extends into the installation cavity 21.

[0056] Specifically, the embedded air conditioner indoor unit 200 provided in the embodiment of the present application can realize the function that the air return enters the chamber of the embedded air conditioner indoor unit 200 for heat exchange, and the air after heat exchange is discharged from the air outlet 22 to the indoor of the building. Figure 6As shown, in the embedded air conditioner indoor unit 200 of the embodiment of the present application, the upper part of the water receiving tray 12 is fixed in the housing 11, and the bottom of the water receiving tray 12 protrudes from the lower end surface 112 of the housing 11 and extends into the installation cavity 21, so that the water receiving tray 12 is accommodated in the cavity formed by the body 1 and the panel 2, and a part of the structure of the water receiving tray 12 extends into the installation cavity 21 of the panel 2. The height design of the body 1 does not need to consider the height that must completely accommodate the water receiving tray 12. In the air conditioner indoor unit 100 of the prior art, the water receiving tray 12 is entirely located above the panel 2, that is, the water receiving tray 12 is entirely accommodated inside the body 1. The height of the body 1 of the embedded air conditioner indoor unit 200 of the embodiment of the present application can be designed to be lower than the height of the body 1 of the air conditioner indoor unit 100 of the prior art, so the overall height of the embedded air conditioner indoor unit 200 of the embodiment of the present application can be designed to be lower. Taking the 3200W power air conditioner indoor unit currently on the market as an example, the body height of the air conditioner indoor unit 100 in the prior art is 340 mm, while the body height of the embedded air conditioner indoor unit 200 provided in the embodiment of the present application is only 280 mm.

[0057] The embedded air conditioner indoor unit 200 of the present application can be used in X space (including special scenes such as kitchen, bathroom, cloakroom, entrance hall, etc.), and the indoor floor height of X space is slightly lower than the indoor floor height of bedroom and living room. Fig.11 The bar graph shows the distribution of ceiling heights in kitchens of fine residential buildings. Fig.11 It can be seen that 13.5% of the kitchen ceiling heights of fine residential buildings are lower than 2.3m, while the comfortable height for human activities is greater than or equal to 2.4m. The overall height of the air conditioner indoor unit in the X space determines the height of the ceiling. If the air conditioner indoor unit 100 of the prior art is installed in the X space, the ceiling height will be low, causing a sense of oppression.

[0058] The embedded air conditioner indoor unit 200 of the embodiment of the present application makes full use of the space through the layout design between the body 1, the water tray 12 and the panel 2, reduces the overall height of the body 1, and can improve the height of the ceiling after installation, thereby improving the oppressive feeling caused by the floor height problem in the X-space scene.

[0059] In some exemplary embodiments, Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the body 1 further includes an electric control box 13 , the upper portion of which is fixed in the housing 11 , and the lower portion of which protrudes from the lower end surface 112 of the housing 11 and extends into the installation cavity 21 .

[0060] Specifically, in the embedded air conditioner indoor unit 200 of the embodiment of the present application, the upper part of the electric control box 13 is fixed in the housing 11, and the lower part of the electric control box 13 protrudes from the lower end surface 112 of the housing 11 and extends into the installation cavity 21 of the panel 2, so that a part of the electric control box 13 is located in the housing 11, and another part of the electric control box 13 is located in the installation cavity 21 of the panel 2, so the height of the panel 2 of the present application is set to accommodate a part of the height of the electric control box 13. In the air conditioner indoor unit 100 of the prior art, the height of the electric control box 13 is set to be entirely located inside the panel 2. In order to meet the requirements of the electric control layout, the thickness of the panel 2 must be increased, and the height of the panel 2 of the embedded air conditioner indoor unit 200 of the present application can be lower than the height of the panel 2 of the air conditioner indoor unit 100 of the prior art, so the overall height of the embedded air conditioner indoor unit 200 of the present application can be designed to be lower, thereby increasing the height of the indoor ceiling, reducing the sense of oppression of the indoor personnel, and improving the comfort of the indoor personnel.

[0061] In some exemplary embodiments, Figure 6 , Figure 7 and Figure 8 As shown, the bottom of the water receiving tray 12 is provided with an upwardly recessed mounting groove 121 , and the upper part of the electric control box 13 is accommodated in the mounting groove 121 .

[0062] Specifically, an upwardly recessed mounting groove 121 is provided at the bottom of the water receiving tray 12, and the upper part of the electric control box 13 is accommodated in the mounting groove 121, which is conducive to making full use of the space on one side of the water receiving tray 12 to accommodate the electric control box 13, thereby helping to reduce the length and height of the body 1, and reduce the ceiling height occupied by the installation of the embedded air conditioner indoor unit 200.

[0063] In some exemplary embodiments, Figure 6 , Figure 7 and Figure 8 As shown, a protrusion 122 protruding downward is provided at the bottom of the water receiving tray 12 . The protrusion 122 protrudes from the lower end surface 112 of the housing 11 and extends into the installation cavity 21 . The installation groove 121 is located on one side of the protrusion 122 .

[0064] Specifically, the downwardly protruding portion 122 provided at the bottom of the water receiving tray 12 forms a concave cavity for holding water dripping from the indoor heat exchanger 17. The protruding portion 122 protrudes from the lower end surface 112 of the casing 11 and extends into the mounting cavity 21 of the panel 2, which is conducive to reducing the height of the fuselage 1. The mounting groove 121 is arranged on one side of the protruding portion 122, so that the protruding portion 122 of the water receiving tray 12 and the electric control box 13 are arranged alternately, which is conducive to fully utilizing the space on one side of the water receiving tray 12 to accommodate the electric control box 13, thereby helping to reduce the length and height of the fuselage 1.

[0065] In some exemplary embodiments, Figure 6 , Figure 7 and Figure 8 As shown, a partition 14 is provided in the casing 11 , and the two sides of the partition 14 are a return air chamber 15 and an air outlet chamber 16 , respectively. The water receiving tray 12 and the electric control box 13 are both fixed to the air outlet chamber 16 , and the mounting groove 121 is located on the side of the protrusion 122 close to the partition 14 .

[0066] Specifically, Figure 6 The double-line arrow in the figure shows the airflow direction of the embedded air conditioner indoor unit 200 of the present application when it is working. The airflow flows from the return air port 23 into the return air chamber 15, then flows into the outlet air chamber 16, and finally flows out from the outlet air port 22. The airflow exchanges heat with the indoor heat exchanger 17 in the outlet air chamber 16 of the embedded air conditioner indoor unit 200. The partition 14 is used to separate the return air chamber 15 and the outlet air chamber 16 to form two chambers with different functions. The mounting groove 121 is arranged to be located on one side of the protrusion 122 of the water receiving tray 12 close to the partition 14 ( Figure 6 The right side of the figure shows that the internal components of the embedded air conditioner indoor unit 200 are arranged compactly, which is beneficial to reducing the overall size of the embedded air conditioner indoor unit 200.

[0067] In some exemplary embodiments, Figure 7 As shown, the lower end surface of the partition 14 is higher than the lower end surface 112 of the casing 11, the upper end surface of the first cavity wall 211 of the installation cavity 21 extends into the casing 11, and cooperates with the partition 14 to separate the return air cavity 15 and the outlet air cavity 16, and the electrical control box 13 is located between the protrusion 122 and the first cavity wall 211.

[0068] Specifically, the partition plate 14 and the first cavity wall 211 can be abutted and matched to separate the return air cavity 15 and the outlet air cavity 16, two cavities with different functions. The electric control box 13 is arranged between the protrusion 122 and the first cavity wall 211. The protrusion 122 and the first cavity wall 211 both have a limiting effect on the electric control box 13. The protrusion 122 and the first cavity wall 211 can also protect the electric control box 211 from water droplets, dust particles and impurities in the external airflow.

[0069] In some exemplary embodiments, Figure 7 As shown, a first support portion 141 extending toward the air outlet cavity 16 is provided at the lower end of the partition 14 , and one end of the water receiving tray 12 is supported on the first support portion 141 .

[0070] A second supporting portion 2111 extending toward the air outlet cavity 16 is disposed at an upper end of the first cavity wall 211 of the installation cavity 21 , and the first supporting portion 141 is supported on the second supporting portion 2111 .

[0071] Specifically, Figure 7As shown, one end of the water tray 12 is supported on the first support portion 141, so that the first support portion 141 limits and fixes the water tray 12. The first support portion 141 is supported on the second support portion 2111, so that the partition 14 and the first cavity wall 211 cooperate to divide the cavity of the embedded air conditioner indoor unit 200 into two cavities with different functions, the return air cavity 15 and the outlet air cavity 16. In addition, the first cavity wall 211 can support the first support portion 141 and the water tray 12. The above structure is simple in design and easy to process and install.

[0072] In some exemplary embodiments, Figure 6 , Figure 7 and Figure 8 As shown, the fuselage 1 also includes an indoor heat exchanger 17, the upper part of the indoor heat exchanger 17 is fixed in the casing 11, the lower part of the indoor heat exchanger 17 protrudes from the lower end surface 112 of the casing 11 and extends into the installation cavity 21, and the indoor heat exchanger 17 is located above the water receiving tray 12.

[0073] Specifically, the indoor heat exchanger 17 is arranged above the water receiving pan 12 so that water droplets condensed on the outer surface of the indoor heat exchanger 17 generated by heat exchange between the indoor heat exchanger 17 and the outside airflow can drip into the water receiving pan 12, thereby preventing the embedded air conditioner indoor unit 200 from dripping into the room. The indoor heat exchanger 17 can be designed as a finned heat exchanger or other types of heat exchangers.

[0074] The lower part of the indoor heat exchanger 17 is arranged to protrude from the lower end surface 112 of the casing 11 and extend into the mounting cavity 21 of the panel 2, so that a part of the indoor heat exchanger 17 is located in the body 1, and another part of the indoor heat exchanger 17 is located in the mounting cavity 21 of the panel 2. In the prior art air conditioner indoor unit 100, the entire height of the water receiving pan 12 is arranged in the body 1 above the panel 2, so the height of the body 1 is relatively high, while the height of the body 1 of the embedded air conditioner indoor unit 200 of the embodiment of the present application can be designed to be lower, thereby reducing the overall height of the embedded air conditioner indoor unit 200 of the embodiment of the present application, which is conducive to improving the height of the ceiling.

[0075] In some exemplary embodiments, Figure 6 , Figure 7 and Figure 8 As shown, a water receiving chamber 123 is formed in the water receiving tray 12 , part of the water receiving chamber 123 is formed in the protrusion 122 , and the lower part of the indoor heat exchanger 17 extends into the part of the water receiving chamber 123 formed in the protrusion 122 .

[0076] Specifically, the lower portion of the indoor heat exchanger 17 of the embodiment of the present application extends into the portion of the water receiving tray 12 formed in the protrusion 122, and the electric control box 13 is accommodated in the installation groove 121 on one side of the protrusion 122 of the water receiving tray 12. In this way, the indoor heat exchanger 17 and the electric control box 13 are staggered, which is beneficial to reducing the overall height of the embedded air conditioner indoor unit 200 and the ceiling height occupied by the embedded air conditioner indoor unit 200 when it is installed.

[0077] In some exemplary embodiments, Figure 6 , Figure 7 and Figure 8 As shown, the indoor heat exchanger 17 is arranged to be inclined relative to the horizontal direction, and the indoor heat exchanger 17 has a windward surface 171 , and the windward surface 171 is perpendicular to the direction of the airflow blowing toward the windward surface 171 .

[0078] Specifically, the windward surface 171 of the indoor heat exchanger 17 is arranged to be perpendicular to the direction of the airflow blowing toward the windward surface 171 , so as to improve the heat exchange efficiency of the indoor heat exchanger 17 .

[0079] In some exemplary embodiments, Figure 6 As shown, an air outlet duct 3 is formed in the casing 11 , and along the flow direction of air, the air outlet duct 3 is located downstream of the indoor heat exchanger 17 .

[0080] The air outlet duct 3 includes a curved duct wall 31 , and the panel 2 is provided with an air outlet 22 . One end of the curved duct wall 31 extends to the upper end of the indoor heat exchanger 17 , and the other end extends to the air outlet 22 provided on the panel 2 . The air outlet duct 3 is connected to the air outlet 22 .

[0081] Specifically, the air outlet duct 3 includes a curved air duct wall 31, which is beneficial to reducing the flow resistance of the airflow in the air outlet duct 3. In this way, the curved air duct wall 31 of the present application does not have wind field resistance structures such as sharp angles and right angles. The structural design of the air outlet duct 3 of the present application is beneficial to wind field distribution and rapid return air outlet.

[0082] The air conditioner indoor unit 100 of the prior art, such as Figure 1 As shown, the outer shape design of the air duct wall of the air outlet duct 3 is limited by the outer shape of the casing and is arranged in the form of a combination of a straight air duct wall and an arc-shaped air duct wall. The airflow has wind field resistance in the straight section of the air duct wall of the air outlet duct 3, resulting in a slow air outlet speed.

[0083] Fig.12 The embedded air conditioner indoor unit 200 (i.e. Fig.12 In this application, Figure 6 ) and an indoor unit of an air conditioner having a combination of a straight duct wall and a curved duct wall (ie Fig.12 Similar products in Figure 8 The experimental results of the air volume comparison are shown in Figure 2. Fig.12 It can be seen that under the same conditions, through simulation analysis, the air volume at the air outlet 22 of the embedded air conditioner indoor unit 200 with the curved air duct wall 31 is increased. For example, by optimizing the air duct structure, the air volume can be increased by 5.3%.

[0084] In some exemplary embodiments, Figure 3 and Figure 6 As shown, the casing 11 includes a first casing wall 111, which is adjacent to the curved air duct wall 31 and arranged opposite to the curved air duct wall 31. The first casing wall 111 is provided with a convex structure 1111 protruding outward, and a gap 4 for accommodating the insulation layer is formed between the first casing wall 111 and the curved air duct wall 31.

[0085] Specifically, the first shell wall 111 is provided with a convex structure 1111 protruding outwards to leave space for the curved surface of the curved air duct wall 31. The first shell wall 111 is provided with a convex structure 1111 protruding outwards, which is conducive to increasing the width of the gap 4 of the insulation layer, thereby improving the insulation effect of the embedded air conditioner indoor unit 200 and avoiding condensation on the outer surface of the shell 11.
