Description

Wall-mounted air conditioner

Technical Field

The invention 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.

Disclosure of Invention

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 3 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 3. The heat exchanger 10' of the wall-mounted air conditioner 1' is disposed around the cross flow wind wheel 20 '. Specifically, a first part 11 'of the heat exchanger 10' in a general inverted V shape is located above the cross-flow wind wheel 20', and a 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 water receiving tray 30' is opposite to the rear lower end 111' of the first part 11' in the vertical direction, and the water receiving tray 30' is positioned between the rear lower end 111' of the first part 11' and the cross-flow wind wheel 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 duct 50' with a 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 60', the intake duct 50' is relatively narrow, i.e., the flow rate of air flowing through the intake duct 50' is relatively small, thereby resulting in relatively low heat exchange efficiency of the second portion 12 '.

Furthermore, the inventors have found that: in the related art, the wall-mounted air conditioner throttling part is generally installed at a side portion (e.g., a left side portion and/or a right side portion) in a length direction of the body, or the throttling part is separately externally installed outside the body and installed in a separate sealing box. The latter is mainly that some models put the throttling part in an independent silencing sealing box to achieve the silencing effect in order to meet the requirements of the noise level of the bedroom. The above two mounting methods have the following disadvantages: 1) The throttle component is arranged on the side part of the machine body in the length direction, so that the space of the machine body in the length direction is sacrificed, the length of the machine body is controlled to meet the miniaturization requirement, the safety clearance of a pipeline is further compressed, and the difficulty in manufacturing and assembling the pipeline is increased; 2) The throttling component is fixedly arranged in the independent silencing sealing box, so that the refrigerant noise can be reduced, but the throttling component is independent of the independent sealing box outside the machine body, so that the aesthetic feeling is influenced, and meanwhile, the independent sealing box has the hidden danger of generating condensed water.

The present invention is directed to solving, at least in part, one of the technical problems in the related art. To this end, embodiments of the present invention provide a wall-mounted air conditioner.

The wall-mounted air conditioner comprises a machine shell, a throttling component and a heat exchanger, wherein an air duct is arranged in the machine shell, the air duct is provided with an air inlet and an air outlet and comprises an air inlet section and an air outlet section which are connected, at least one part of the air inlet is positioned on the front surface of the machine shell, the air inlet section extends forwards from the air outlet section horizontally or obliquely so as to form an installation space behind the air inlet section, and the throttling component is arranged in the installation space.

At least one part of the air inlet of the wall-mounted air conditioner is positioned on the front surface of the shell, so that air (inlet air) in the environment can enter the air duct from the general front 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, ambient air may not have to enter the duct 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 for an indoor (room) with low height, the sense of oppression of the indoor space can be effectively reduced or eliminated.

Therefore, the wall-mounted air conditioner provided by the embodiment of the invention has very low requirements on the installation space, the installation space only needs to be capable of accommodating the lower wall-mounted air conditioner, an air inlet space does not need to be reserved above the wall-mounted air conditioner, and the application range of the wall-mounted air conditioner can be expanded.

In some alternative embodiments, the portion of the air inlet located on the front side is inclined obliquely upward toward the wall surface (which may be understood as a mounting surface) with respect to the vertical surface. Thus, when a user stands on the indoor ground, the user cannot see the inside of the casing (wall-mounted air conditioner) through the air inlet, and the internal structure of the casing (wall-mounted air conditioner) is not exposed to the user, so that the visual comfort of the user can be improved.

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 at least partly of air intake be located the front of casing, can make the air that enters into in the wind channel via the air intake directly flow through the heat exchanger to carry out the heat transfer fully 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.

Therefore, the wall-mounted air conditioner provided by the embodiment of the invention has the advantages of convenience in installation, improvement on indoor space utilization rate, wide application range and high heat exchange efficiency.

In addition, the air inlet section of the wall-mounted air conditioner provided by the embodiment of the invention extends forwards from the air outlet section horizontally or obliquely, the installation space is formed behind the air inlet section, and the throttling component is installed in the installation space, so that the problem that pipelines such as the throttling component, a distributor and the like are accumulated on the side part of the machine body in the length direction is solved, the installation of the throttling component does not occupy the space of the machine body in the length direction, the length of the machine body is shortened, the space utilization efficiency and the integration level of the wall-mounted air conditioner are improved, the structure of the wall-mounted air conditioner is more compact and reasonable, and the density of the pipelines and the difficulty of assembly and manufacture are reduced. In addition, the installation position of the throttling component is back, which is beneficial to isolating noise and improving user experience compared with the prior art that the throttling component is installed on the side part of the machine body.

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 invention and are not to be construed as limiting the invention.

A wall-mounted type air conditioner 1 according to an embodiment of the present invention will be described with reference to fig. 1 to 3. As shown in fig. 1, the wall-mounted air conditioner 1 includes a cabinet 10, a heat exchanger 20, an air duct 30, and a throttling part 90. The air duct 30 is disposed in the casing 10, the heat exchanger 20 is disposed in the air duct 30, and the air duct 30 includes an air inlet section 313 and an air outlet section 314 connected to each other. The air duct 30 further has an air inlet 311 and an air outlet 312, wherein the air inlet 311 is located at the air inlet section 313, and the air outlet 312 is located at the air outlet section 314.

At least a portion of the intake vent 311 is located on the front 11 of the chassis 10. The front face 11 of the casing 10 is a surface of the casing 10 that can be viewed from a horizontal rearward line of sight, that is, the surface of the casing 10 that can be viewed from 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 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.

The air inlet section 313 extends forwards from the air outlet section 314 horizontally or obliquely forwards so as to form an installation space 50 behind the air inlet section 313, in other words, the air inlet section 313 extends forwards from the connection part of the air inlet section 313 and the air outlet section 314 horizontally or obliquely forwards, the installation space 50 for installing air conditioning components is formed behind the air inlet section 313, and the throttling component 90 is arranged in the installation space 50.

At least one part of the air inlet of the wall-mounted air conditioner is positioned on the front surface of the shell, so that air (inlet air) in the environment can enter the air duct from the general front 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 air duct from at least two directions of the front of the cabinet, the front upper side, and the front lower side.

That is, ambient air may not necessarily enter the duct 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.

In some alternative embodiments, the portion of the air inlet 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 (wall-mounted air conditioner 1) through the air inlet 311, and the internal structure of the cabinet 10 (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. According to the technical scheme, at least one part of the air inlet is located on the front face of the shell, so that air entering the air channel through the air inlet can directly flow through the heat exchanger, and heat exchange can be fully carried out between the air inlet and the heat exchanger. That is to say, the air intake of the wall-mounted air conditioner is not limited by the narrow space at the top, the air is fed from the front of the casing, the air intake can be effectively increased, the flow of the air flowing through the heat exchanger can be obviously 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 side of the machine shell, so that the water-containing tray can not prevent the airflow from flowing to the heat exchanger, for example, the water-containing tray can not flow to the flow path of the heat exchanger through the airflow, and the heat exchange efficiency of the heat exchanger can be greatly improved. Optionally, the water-tray is disposed below the heat exchanger.

In addition, the air inlet section of the wall-mounted air conditioner provided by the embodiment of the invention extends forwards from the air outlet section in a horizontal or inclined manner, the installation space is formed behind the air inlet section, and the throttling component is installed in the installation space, so that the problem that pipelines such as the throttling component and the distributor are accumulated on the side part of the machine body in the length direction is solved, the installation of the throttling component does not occupy the space of the machine body in the length direction, the length of the machine body is shortened, the space utilization efficiency and the integration level of the wall-mounted air conditioner are improved, the structure of the wall-mounted air conditioner is more compact and reasonable, and the density of the pipelines and the difficulty in assembly and manufacture are also reduced. In addition, the installation position of the throttling component is back, which is beneficial to isolating noise and improving user experience compared with the prior art that the throttling component is installed on the side part of the machine body.

The following describes in detail a specific embodiment provided by the present invention with reference to fig. 1 and 2. In the present embodiment, the wall-mounted air conditioner 1 may be installed on a wall surface 2 in a room.

As shown in fig. 1 and 2, the wall-mounted air conditioner 1 includes a cabinet 10, a heat exchanger 20, an air duct 30 provided in the cabinet 10, a wind wheel 40 provided in the air duct 30, and a throttle member 90. The cabinet 10 includes a front plate 111, and an intake opening 311 is provided in the front plate 111.

Further, as shown in fig. 1 and 2, in the present embodiment, the front plate 111 is an arc plate protruding forward, and the front plate 111 includes an upper plate portion 1111 and a lower plate portion 1112. The upper plate portion 1111 is an upper portion of the front plate 111, the lower plate portion 1112 is a lower portion of the front plate 111, and the upper plate portion 1111 is located above the lower plate portion 1112. The air inlet 311 is provided in the upper plate 1111.

In some alternative embodiments, when the casing 10 is installed on the wall surface 2, the distance between the top surface of the casing 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.

Alternatively, the distance between the top surface of the cabinet 10 and the indoor ceiling wall 3 is 15 cm or less. Alternatively, the distance between the top surface of the casing 10 and the indoor ceiling wall 3 is 10 cm or less. Alternatively, the distance between the top surface of the casing 10 and the indoor ceiling wall 3 is not more than 8 cm. Alternatively, the distance between the top surface of the cabinet 10 and the indoor ceiling wall 3 is 5 cm or less. Alternatively, the top surface of the cabinet 10 is in contact with the indoor ceiling wall 3, i.e., the distance between the top surface of the cabinet 10 and the indoor ceiling wall 3 is equal to 0 cm. This can further improve the indoor space utilization.

The wind duct 30 includes an air inlet section 313 and an air outlet section 314 connected with each other, the air inlet section 313 defines an air inlet channel 3136, and the air outlet section 314 defines an air outlet channel 3143. The air inlet 311 of the air duct 30 is located at one end of the air inlet channel 3136, and the air outlet 312 of the air duct 30 is located at one end of the air outlet channel 3143. The heat exchanger 20 is disposed in the air intake passage 3136 and at the air inlet 311, and the heat exchanger 20 is opposite to the air inlet 311 so as to exchange heat with air entering the air intake passage 3136 from the air inlet 311.

A portion of the wind wheel 40 is located in the wind inlet passage 3136, and another portion of the wind wheel 40 is located in the wind outlet passage 3143. The wind wheel 40 is used for generating wind exhaust force, so that air enters the air inlet channel 3136 from the air inlet 311, then enters the air outlet channel 3143 through the wind wheel 40, and finally is exhausted from the air outlet. The wind wheel 40 is arranged in the air duct 30, so that the flow rate and the flow velocity of the air flowing through the heat exchanger 20 can be improved, and the heat exchange efficiency of the heat exchanger 20 and the wall-mounted air conditioner 1 can be further improved.

As shown in fig. 1 and 2, the air inlet section 313 extends obliquely forward and upward from the air outlet section 314, in other words, the air inlet section 313 extends obliquely forward and upward from the connection with the air outlet section 314. An installation space 50 is formed behind the air intake section 313. It will be appreciated that the mounting space 50 is located in front of the wall surface 2. The throttling member 90 is installed in the installation space 50. The throttling part 90 includes a throttling valve 91 and a pipe 92, and the pipe 92 is connected to the throttling valve 91 in the installation space 50 and extends in a length direction of the wall-mounted air conditioner 1. The length direction of the wall-mounted air conditioner 1 may be identical to the length direction of the air duct 30. The length direction of the air duct 30 is indicated by an arrow C in fig. 3.

It should be noted that, in other alternative embodiments, the air inlet section 313 may also extend forward horizontally from the connection of the air outlet section 314, or the air inlet section 313 may also extend forward and downward from the connection of the air outlet section 314. Preferably, as shown in the present embodiment, the air inlet section 313 extends obliquely forward and upward from the connection with the air outlet section 314, so that the structure of the wall-mounted air conditioner 1 is more reasonable.

Further, a portion of the wind outlet section 314 adjacent to the wind outlet 312 extends downward and forward from the rest of the wind outlet section 314, in other words, the wind outlet 314 includes a portion adjacent to the wind outlet 312 and a portion of the wind outlet section 314 adjacent to the wind outlet 312 extends downward and forward from a connection point of the wind outlet section 314 and the rest of the portion. The outlet 312 is provided at the lower portion of the cabinet 10.

Further, the air duct wall of the air intake section 313 includes a first air intake plate 3131 and a second air intake plate 3132, and the first air intake plate 3131 and the second air intake plate 3132 define an air intake passage 3136. The air channel wall of the air outlet section 314 includes a first air outlet plate 3141 and a second air outlet plate 3142, and the first air outlet plate 3141 and the second air outlet plate 3142 define an air outlet channel 3143. For example, the first wind-out plate 3141 has a worm tongue structure, and the second wind-out plate 3142 has a worm gear structure. The installation space 50 is located behind the first air inlet plate 3131. It is understood that the installation space 50 is located in front of the indoor wall 2.

As shown in fig. 1 and 2, the heat exchanger 20 is fitted at the air inlet of the air inlet section 313, and the upper end of the heat exchanger 20 is fitted with the first air inlet plate 3131 and provided with a first sealing structure (not shown) between the first air inlet plate 3131, and the lower end of the heat exchanger 20 is fitted with the second air inlet plate 3132 and provided with a second sealing structure (not shown) between the second air inlet plate 3132. The first and second sealing structures are used for sealing, so that air which is not exchanged heat by the heat exchanger 20 is prevented from entering the air inlet passage 3136 from a gap between the heat exchanger 20 and the first air inlet plate 3131 or between the heat exchanger 20 and the second air inlet plate 3132, and the refrigeration effect of the air conditioner is not affected. Optionally, the first and second sealing structures are sealing foams.

Since the heat exchanger 20 may generate condensed water during the heat exchange process, the condensed water is prevented from flowing into the wind outlet channel 3143 and flowing out from the wind outlet 312. As shown in fig. 1 and 2, the second air inlet plate 3132 includes a recess 3133, and the recess 3133 forms a water receiving groove 3134 for receiving condensed water of the heat exchanger 20. The water receiving groove 3134 is located on one side of the recess 3133 close to the air inlet passage 3136. The depressed portion 3133 is formed by depressing a portion of the second air inlet plate 3132 in a direction away from the return air duct.

In the embodiment shown in fig. 1 and 2, the water receiving groove 3134 is opened upward and has a certain depth in the up-down direction, the water receiving groove 3134 is located behind the lower end of the heat exchanger 20, i.e., behind the second sealing structure, and the water receiving groove 3134 is also located below the heat exchanger 20 so as to effectively receive the condensed water of the heat exchanger 20. Since the recess 3133 forms the water receiving groove 3134, the recess 3133 may also be referred to as a water receiving tray.

Further, a portion of the first air inlet plate 3131 is recessed outward to form an avoiding groove 3135, the avoiding groove 3135 is located behind the upper end of the heat exchanger 20, i.e., behind the first sealing structure, and the avoiding groove 3135 is used for avoiding condensed water formed by the heat exchanger 20, so as to prevent the condensed water from flowing into the air outlet section 314 along the first air inlet plate 3131. Optionally, a portion of the first air inlet plate 3131 adjacent to the air outlet section 314 is recessed outward to form an escape groove 3135.

In some alternative embodiments, the water tank 60 with an upward opening is disposed on the back of the first air inlet plate 3131 and/or the first air outlet plate 3141, and the installation space 50 is located above the water tank 60, that is, the throttling member 90 is located above the water tank. Wherein the water tank 60 is obliquely disposed and communicated with the water receiving tank 3134. The water tank 60 is used to receive condensed water formed on the back surface of the first air inlet plate 3131 and/or the first air outlet plate 3141, and also to receive condensed water of the throttling member 90 installed in the installation space 50. The water in the water tank 60 is collected in the water receiving tank 3134 and then discharged together. The water tank 60 is disposed obliquely, that is, the water tank 60 is disposed obliquely in the longitudinal direction thereof.
