Description

Wall-mounted air conditioner

Technical Field

The utility model relates to the field of air conditioners, in particular to a wall-mounted air conditioner.

Background

In the related art, an air inlet of a wall-mounted air conditioner is disposed at a top portion of the wall-mounted air conditioner, and in order to meet a requirement for air inlet at the top portion, the wall-mounted air conditioner must be spaced apart from an indoor ceiling by a large distance, so that an indoor space utilization rate is low, and an indoor space is more narrow. Furthermore, the wall-mounted air conditioner in the related art has a drawback of low heat exchange efficiency.

SUMMERY OF THE UTILITY MODEL

The present invention is based on the discovery and recognition by the inventors of the following facts and problems:

in the related art, as shown in fig. 4, an air inlet of a wall-mounted air conditioner 1 ' is formed at a top portion thereof, and the top portion of the wall-mounted air conditioner 1 ' must be spaced apart from an indoor ceiling wall by a relatively large distance to form an air inlet space, so that the wall-mounted air conditioner 1 ' cannot be closely attached to the indoor ceiling wall. The heat exchanger 10 ' of the wall-mounted air conditioner 1 ' is disposed around the cross flow wind wheel 20 '. Specifically, the first part 11 'of the heat exchanger 10' in the shape of a substantially inverted V is located above the cross flow wind wheel 20 ', and the second part 12' of the heat exchanger 10 'is located in front of the cross flow wind wheel 20'.

A drain pan 30 ' is provided below the rear lower end 111 ' of the first portion 11 '. The drain pan 30 ' is vertically opposite to the rear lower end 111 ' of the first section 11 ', and the drain pan 30 ' is located between the rear lower end 111 ' of the first section 11 ' and the cross-flow fan 20 '. The inventor has recognized that the rear lower end 111 ' of the first portion 11 ' is shielded by the drip tray 30 ', and thus the rear lower end 111 ' of the first portion 11 ' does not substantially exchange heat with air, resulting in waste and reduced heat exchange efficiency.

The second portion 12 'defines an inlet air duct 50' with the front panel 40 'of the wall-mounted air conditioner 1'. However, the inventor has recognized that since most of the space of the wall-mounted air conditioner 1 ' in the front-rear direction is occupied by the heat exchanger 10 ', the cross-flow wind wheel 20 ' and the scroll casing 60 ', the intake duct 50 ' is made narrower, that is, the flow rate of air flowing through the intake duct 50 ' is made smaller, thereby making the heat exchange efficiency of the second section 12 ' low.

The present invention is directed to solving, at least to some extent, one of the technical problems in the related art. Therefore, an embodiment of the present invention provides a wall-mounted air conditioner, which includes a housing and a heat exchanger, where the heat exchanger is disposed in the housing, the housing has an air duct therein, the air duct has a first air inlet, a second air inlet, and an air outlet, the first air inlet is located on a front surface of the housing, and the second air inlet is located on a top surface of the housing.

The wall-mounted air conditioner of the embodiment of the utility model has the advantages that the first air inlet is positioned at the front side of the shell, the second air inlet is positioned at the top surface of the shell, and air (inlet air) in the environment can enter the air channel from the general front side of the shell. For example, air (intake air) in the environment may enter the air duct from the front of the casing, may enter the air duct from the front upper side of the casing, and may enter the air duct from the front lower side of the casing. Further, air in the environment may enter the duct from at least two directions of a front, a front upper direction, and a front lower direction of the cabinet.

That is, the air in the environment may not necessarily enter the duct entirely from directly above the cabinet. Therefore, the distance between the wall-mounted air conditioner and the indoor top wall can be greatly reduced or eliminated, the indoor space utilization rate can be improved, and particularly, the sense of oppression of the indoor space can be effectively reduced or eliminated for an indoor (room) with lower height. Therefore, the wall-mounted air conditioner according to the embodiment of the present invention has a low requirement for an installation space, and can expand the application range of the wall-mounted air conditioner.

In the technical scheme of this application, make first air intake be located the front of casing, can make the air that enters into in the wind channel via first air intake directly flow through the heat exchanger to fully carry out the heat transfer with the heat exchanger. That is, the air intake of the wall-mounted air conditioner is not limited by the narrow space at the top, and air is supplied from the front of the casing, so that the air intake can be effectively increased, the flow of the air flowing through the heat exchanger can be remarkably improved, and the heat exchange efficiency of the heat exchanger can be greatly improved.

In this application, at least a part of air intake is located the front of casing, need not to set up the heat exchanger of the shape of roughly falling V in the below of air intake, just also need not to set up the water collector that the width is greater than or equal to the width of the heat exchanger of roughly falling V at the lower tip department of the heat exchanger of roughly falling V just so as to avoid causing because of the water collector shelters from that some of heat exchanger does not basically carry out the heat transfer with the air. At least one part of the air inlet is positioned on the front face of the machine shell, so that the water pan can not prevent airflow from flowing to the heat exchanger, for example, the water pan can not flow to the flow path of the heat exchanger through the airflow, and thus the heat exchange efficiency of the heat exchanger can be greatly improved. Optionally, the water-tray is disposed below the heat exchanger.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

A wall-mounted type air conditioner 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in fig. 1 to 3, a wall-mounted air conditioner 1 according to an embodiment of the present invention includes a cabinet 10 and a heat exchanger 20, the heat exchanger 20 being provided in the cabinet 10. The casing 10 has an air duct 30 therein, and the air duct 30 has a first air inlet 311, a second air inlet (not shown), and an air outlet 312. The first air inlet 311 is located on the front surface 11 of the casing 10, and the second air inlet is located on the top surface 12 of the casing 10. The first air inlet 311 and the second air inlet are used for air inlet of the wall-mounted air conditioner 1.

Here, the front face 11 of the casing 10 is a surface of the casing 10 that can be seen by a horizontal rearward line of sight, that is, the surface of the casing 10 that can be seen by a horizontal rearward line of sight is the front face 11 of the casing 10. For example, when the eyes of the observer and the casing 10 are located at substantially the same level and the observer is located in front of the casing 10, the surface of the casing 10 that the observer can see is the front face 11 of the casing 10. The top surface 12 of the enclosure 10 is the surface at the top of the enclosure 10 that is generally not visible to an observer positioned in front of the enclosure 10.

The front-back direction is indicated by an arrow a in fig. 1, and the up-down direction is indicated by an arrow B in fig. 1. For example, the wall-mounted air conditioner 1 may be installed on a wall surface 2. The direction away from the wall surface 2 along the horizontal direction is forward, and the direction away from the wall surface 2 along the horizontal direction is backward.

In some alternative embodiments, the portion of the first intake vent 311 located on the front surface is inclined obliquely upward toward the wall surface 2 (which may be understood as a mounting surface) with respect to the vertical surface. In this way, when the user stands on the indoor floor, the user cannot see the inside of the cabinet 10 (the wall-mounted air conditioner 1) through the first air inlet 311, and the internal structure of the cabinet 10 (the wall-mounted air conditioner 1) is not exposed to the user, which can improve the visual comfort of the user.

Moreover, in a scene of top air inlet, the top space is often limited and narrow, so that the air inlet amount is limited due to the narrow top space. In the technical scheme of this application, make first air intake be located the front of casing, can make the air that enters into in the wind channel via first air intake directly flow through the heat exchanger to exchange heat with the heat exchanger fully. That is, the air intake of the wall-mounted air conditioner is not limited by the narrow space at the top, and air is supplied from the front of the casing, so that the air intake can be effectively increased, the flow of the air flowing through the heat exchanger can be remarkably improved, and the heat exchange efficiency of the heat exchanger can be greatly improved.

In the present application, at least a portion of the air inlet 311 is located on the front surface of the casing 10, and there is no need to provide a heat exchanger in a substantially inverted V shape below the air inlet 311, that is, there is no need to provide a water pan having a width greater than or equal to that of the heat exchanger in a substantially inverted V shape at a lower end of the heat exchanger in a substantially inverted V shape, so as to avoid that a portion of the heat exchanger does not exchange heat with air substantially due to shielding of the water pan. At least a part of the air inlet 311 is located on the front surface of the casing 10, so that the water pan 15 may not prevent the air flow from flowing to the heat exchanger, for example, the water pan 15 may not pass through the flow path of the air flow to the heat exchanger 20, which may greatly improve the heat exchange efficiency of the heat exchanger 20. Optionally, a water-tray 15 is provided below the heat exchanger 20.

Alternatively, the first air inlet 311 and the second air inlet may be a single air inlet. In other words, the wall-mounted air conditioner 1 according to the embodiment of the present invention has an air inlet, a portion of which (the first air inlet 311) is located on the front surface 11 of the casing 10, and another portion of which (the second air inlet) is located on the top surface 12 of the casing 10.

It should be noted that only the first air inlet 311 located on the front surface 11 of the cabinet 10 is shown in the wall-mounted air conditioner 1 shown in fig. 1 to 3.

The wall-mounted air conditioner 1 according to an embodiment of the present invention includes a cabinet 10 and a heat exchanger 20. The cabinet 10 may be installed on a wall surface 2 in a room.

In some alternative embodiments, when the cabinet 10 is installed on the wall surface 2, the distance between the top surface 12 of the cabinet 10 and the indoor top wall 3 is less than or equal to 20 cm. In other words, the minimum distance between the cabinet 10 and the indoor ceiling wall 3 in the vertical direction is 20 cm or less. This can further improve the indoor space utilization. Optionally, the distance between the top surface 12 of the casing 10 and the indoor top wall 3 is 15 cm or less. Alternatively, the distance between the top surface 12 of the casing 10 and the indoor ceiling wall 3 is 10 cm or less. Alternatively, the distance between the top surface 12 of the casing 10 and the indoor top wall 3 is less than or equal to 8 cm. Alternatively, the distance between the top surface 12 of the casing 10 and the indoor ceiling wall 3 is 5 cm or less.

As shown in fig. 1-3, in an alternative embodiment of the present invention, the upper edge of the front side 11 of the cabinet 10 meets the back side 13 of the cabinet 10 through the top side 12 of the cabinet 10. The lower edge of the front 11 of the casing 10 is directly connected to the back 13 of the casing 10, or the lower edge of the front 11 of the casing 10 is connected to the back 13 of the casing 10 through the bottom 14 of the casing 10, so that the appearance of the casing 10 and the wall-mounted air conditioner 1 is more neat and beautiful.

The top surface 12 may be horizontal, i.e., the top surface 12 may extend horizontally rearward from the front surface 11, the top surface 12 not being visible by a horizontal rearward line of sight. Further, the top surface 12 may be a slope inclined downward rearward. That is, the top surface 12 may be a sloped surface, and the top surface 12 may extend rearwardly and downwardly from the front surface 11, the top surface 12 not being visible from a horizontal rearward line of sight.

The heat exchanger 20 is provided in the cabinet 10. The casing 10 has an air duct 30 therein, and the air duct 30 has a first air inlet 311, a second air inlet, and an air outlet 312. Optionally, the outlet vent 312 is positioned lower than each of the first inlet vent 311 and the second inlet vent. This makes it possible to make the structure of the wall-mounted air conditioner 1 more reasonable.

The heat exchanger 20 is provided in the air duct 30, and the heat exchanger 20 is opposed to each of the first air intake opening 311 and the second air intake opening. The air can flow more directly through the heat exchanger 20, and the heat exchange efficiency of the heat exchanger 20 and the wall-mounted air conditioner 1 can be further improved. In some alternative embodiments, the heat exchanger 20 includes one, the heat exchanger 20 and the first air intake 311 and the second air intake. In other alternative embodiments, the heat exchanger 20 may also include two, i.e., the first air intake opening 311 may be opposite to its corresponding one of the heat exchangers 20, and the second air intake opening may be opposite to its corresponding other heat exchanger 20. In the present embodiment, the heat exchanger 20 includes one.

As shown in fig. 1 and 2, the wall-mounted air conditioner 1 further includes a wind wheel 40 disposed inside the air duct 30, and the heat exchanger 20 is disposed between each of the first and

second air inlets

311 and 40 and the wind wheel. The wind wheel 40 is disposed in the wind tunnel 30 to increase the flow rate and velocity of the air flowing through the heat exchanger 20, so as to further improve the heat exchange efficiency of the heat exchanger 20 and the wall-mounted air conditioner 1.

Optionally, as shown in fig. 1 and fig. 2, the air duct 30 includes an air inlet duct 321 and an air outlet duct 322, and the wind wheel 40 is disposed at a junction of the air inlet duct 321 and the air outlet duct 322, so that the structure of the wall-mounted air conditioner 1 is more reasonable. For example, a portion of the wind wheel 40 may be disposed in the air inlet duct 321, and the remaining portion of the wind wheel 40 may be disposed in the air outlet duct 322.

As shown in fig. 1 and 2, in a vertical plane orthogonal to the length direction (the C direction shown in fig. 3) of the air duct 30, a first included angle θ 1 between a center line L1 of the air outlet duct 322 and a center line L2 of the air inlet duct 321 is greater than or equal to 10 degrees and less than or equal to 85 degrees, which can avoid a large change in the flow direction of the air in the air duct 30, so as to reduce the flow resistance of the air, and can also make the air flow smoothly in the air duct 30, so as to further improve the cooling and heating effects of the wall-mounted air conditioner 1.

Optionally, the first included angle θ 1 is greater than or equal to 20 degrees and less than or equal to 80 degrees. Alternatively, the first included angle θ 1 is 40 degrees or more and 75 degrees or less. Alternatively, the first included angle θ 1 is 60 degrees or more and 75 degrees or less. Alternatively, the first included angle θ 1 is 70 degrees or more and 75 degrees or less. Therefore, the air can flow more smoothly in the air duct 30, and the cooling and heating effects of the wall-mounted air conditioner 1 can be further improved.

Alternatively, the first included angle θ 1 may be, for example, but not limited to, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 71 degrees, 72 degrees, 73 degrees, 74 degrees, 75 degrees, 76 degrees, 77 degrees, 78 degrees, 79 degrees, 80 degrees, or 85 degrees.

As shown in fig. 1 and 2, the first side 3221 of the projection of the air outlet duct 322 intersects with the first side 3211 of the projection of the air inlet duct 321 at a first boundary point F, and the rotation axis of the wind wheel 40 intersects with the vertical plane at a base point O. Wherein a second angle θ 2 between a first line L3 between the base point O and the first boundary point F and a horizontal line L5 forward from the base point O is 60 degrees or more and 150 degrees or less. That is, a first horizontal line including a front horizontal section located forward of the base point O passes through the base point O, and a second included angle θ 2 of the front horizontal section and the first connection line L3 is 60 degrees or more and 150 degrees or less.

Therefore, at least one part of the air inlet (the opening of the air outlet duct 322 adjacent to the air inlet duct 321) of the air outlet duct 322 is opened forward and upward, so that the air flowing through the air inlet 311 and the air inlet duct 321 can enter the air outlet duct 322 more smoothly, and the cooling and heating effects of the wall-mounted air conditioner 1 are improved. In other words, at least a portion of the air outlet of the air inlet duct 321 (the opening of the air inlet duct 321 adjacent to the air outlet duct 322) is opened backwards and downwards, so that the air in the air inlet duct 321 can enter the air outlet duct 322 more smoothly, and the cooling and heating effects of the wall-mounted air conditioner 1 are improved.

Optionally, the second included angle θ 2 is greater than or equal to 70 degrees and less than or equal to 130 degrees. Alternatively, the second included angle θ 2 is equal to or greater than 80 degrees and equal to or less than 120 degrees.

As shown in fig. 1 and 2, the axis of rotation of wind rotor 40 may be perpendicular to the vertical plane; or the vertical plane is perpendicular to the horizontal plane and the axis of rotation of wind rotor 40 is parallel to the horizontal plane. The first boundary point F and the end point of the first side 3221 far away from the air outlet 312 may be the same point.

As shown in fig. 1 and 2, in a vertical plane orthogonal to the length direction of the air duct 30, a minimum distance H1 between a first side 3221 of the projection of the air outlet duct 322 and the outer contour 41 of the projection of the wind wheel 40 is greater than or equal to 4 mm and less than or equal to 8 mm. The space occupied by the duct 30 can be reduced and the space occupied by the wall-mounted air conditioner 1 can be reduced while ensuring the flow rate of air flowing through the outlet duct 322 (the air output volume of the outlet duct 322).

Optionally, a minimum distance H1 between the first side 3221 of the projection of the air outlet duct 322 and the outer contour 41 of the projection of the wind wheel 40 is greater than or equal to 5 mm and less than or equal to 7 mm.

Or, the minimum distance H1 between the first side 3221 of the projection of the air outlet duct 322 and the outer contour 41 of the projection of the wind wheel 40 is greater than or equal to 5.6 mm and less than or equal to 5.9 mm. The space occupied by the duct 30 can be reduced and the space occupied by the wall-mounted air conditioner 1 can be reduced while ensuring the flow rate of air flowing through the outlet duct 322 (the air output volume of the outlet duct 322).

Alternatively, the minimum distance H1 between the projected first side 3221 of the outlet air duct 322 and the projected outer contour 41 of the wind wheel 40 may be, for example, but not limited to, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 5.6 mm, 5.7 mm, 5.75 mm, 5.8 mm, 5.9 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, or 8 mm.

The vertical upward direction is shown by arrow D in fig. 1. The air leaving the air outlet duct 322 can flow downwards and forwards, that is, the wall-mounted air conditioner 1 can discharge cold air (hot air) downwards and forwards, and the cooling and heating effects of the wall-mounted air conditioner 1 can be further improved.

Also, the air outlet duct 322 may have an installation space in front and/or rear thereof so that components originally installed at a side (e.g., a left side and/or a right side) in a longitudinal direction of the air duct 30 are installed in the installation space.
