Description

TECHNICAL FIELD

[0001] The present application relates to the field of air conditioning technology, and in particular to a vertical air conditioner indoor unit. BACKGROUND

[0002] The existing vertical air conditioner indoor unit usually has an air outlet on the front side of the shell, which is mainly used for blowing air forward. A wind guide device, such as a wind guide plate, a vertical swing leaf, etc., is arranged at the air outlet to guide the air flow horizontally, so that the air flow is blown to the front, left front, right front, etc. of the air conditioner.

[0003] In recent years, a micro-wind air supply technology has appeared. A hole is opened on the shell of the air conditioner. In the micro-wind mode, the original air outlet is closed, and the air flow is forced to blow out through the hole on the shell, realizing the micro-wind effect and making the human body more comfortable. However, in the micro-wind mode, the air flow direction cannot be guided by the wind guide device, and the air can only be blown to the area where the micro-hole originally points, so that the air conditioner loses the function of zone air supply. SUMMARY

[0004] The purpose of the present application is to overcome the above problems or at least partially solve the above problems, and to provide a vertical air conditioner indoor unit that can better balance the micro-wind function and the zone air supply function to meet the different needs of users.

[0005] A further purpose of the present application is to expand the air outlet angle range of the vertical air conditioner indoor unit.

[0006] In particular, the present application provides a vertical air conditioner indoor unit, comprising:

[0007] a shell defining an air duct having an air outlet; and

[0008] two micro-wind plates configured to disperse the air flow penetrating therethrough, and vertically arranged in front of the shell along the transverse direction of the shell, each of the micro-wind plates and the shell forming a side flow passage in communication with the air outlet, and the two micro-wind plates forming an air outlet interval opposite to the air outlet; and

[0009] The vertical air conditioner indoor unit is configured to selectively blow the air flow of the air outlet out through one or more of the air outlet interval and the two micro-wind plates.

[0010] Optionally, the vertical air conditioner indoor unit further comprises:

[0011] a wind baffle rotatably arranged in front of the air outlet about a vertical axis, for guiding the air flow of the air outlet to any one of the side flow passages or blowing the air flow out from the air outlet interval.

[0012] Optionally, the wind baffle is configured to be rotatable to a closed position to block the air outlet interval.

[0013] Optionally, the air outlet directions of the two micro wind baffles are obliquely forward and away from each other.

[0014] Optionally, one side of each micro wind baffle close to the lateral edge of the front side of the shell is a first side, and one side close to the lateral center of the shell is a second side.

[0015] Each micro wind baffle gradually moves away from the front side of the shell in the direction from the first side to the second side.

[0016] Optionally, each micro wind baffle is curved with a convex front side.

[0017] Optionally, the first side abuts against the shell, and the second side has a gap with the front surface of the shell to form the side flow channel.

[0018] Optionally, each micro wind baffle is a grid structure.

[0019] Optionally, the grid densities of the two micro wind baffles are different to make the air permeability of the two different.

[0020] Optionally, the vertical air conditioner indoor unit further comprises:

[0021] A vertical swing vane is rotatably arranged in the air duct to guide the lateral air outlet angle of the air flow.

[0022] The vertical air conditioner indoor unit of the present application particularly adds two micro wind baffles, which are located in front of the shell and form an air outlet interval opposite to the air outlet, that is, the two micro wind baffles are arranged on the left and right sides of the air outlet. In this way, when the vertical air conditioner indoor unit needs to blow air forward, the main part of the air flow of the air outlet blows directly forward, and the air flow blows to the indoor environment through the air outlet interval. When the micro wind is needed, the air flow blows to and penetrates the two micro wind baffles to form the micro wind effect. When the micro wind is needed to be blown to the left area, the air flow blows to the left micro wind baffle, and when the micro wind is needed to be blown to the right area, the air flow blows to the right micro wind baffle. As can be seen from the above, the vertical air conditioner indoor unit of the present application can meet the various air supply needs of users by combining the micro wind function and the zoned air supply function.

[0023] In addition, the vertical air conditioner indoor unit of the present application realizes the micro wind function by adding two micro wind baffles outside the shell, and the structure of the vertical air conditioner indoor unit is changed little, and the internal structure of the shell even does not need to be changed, which is convenient for mass production.

[0024] Further, in the indoor unit of the vertical air conditioner, each air baffle gradually moves away from the front side of the shell in a direction from a first edge close to the lateral edge of the front side of the shell to a second edge, and the first edge is attached to the shell, and the second edge has a space with the front surface of the shell, so that the air baffle and the shell are fixed, and the connection between the air baffle and the shell is smooth, and the appearance of the shell is not affected by the air baffle.

[0025] Further, in the indoor unit of the vertical air conditioner, the air out directions of the two air baffles are towards the front and away from each other, so as to expand the air out angle range of the indoor unit of the vertical air conditioner, and when the two air baffles out air at the same time, the two air flows on the left and right sides are expanded horizontally at a larger angle.

[0026] The above and other objects, advantages and features of the present application will become more apparent from the following detailed description of some embodiments thereof, when taken in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS

[0036] The embodiment of the present application provides a vertical air conditioner indoor unit. The vertical air conditioner indoor unit is a kind of indoor unit type of household air conditioner or commercial air conditioner. Air conditioner is used to adjust indoor air, including adjusting the temperature, humidity, air quality of air, humidifying, dehumidifying indoor air, introducing fresh air and the like. Air conditioner can be composed of evaporator, condenser, compressor, throttling device and other necessary elements to form a vapor compression refrigeration cycle system, and output cold air / warm air by fan, to realize refrigeration and heating of indoor environment.

[0037] Figure 1 It is a schematic front view of the vertical air conditioner indoor unit according to an embodiment of the present application; Figure 2 It is a schematic cross-sectional view of the vertical air conditioner indoor unit according to an embodiment of the present application; Figure 3 It is Figure 2 The schematic diagram of the vertical air conditioner indoor unit shown in the drawing is when the air baffle guides the air flow to the left; Figure 4 It is Figure 2A schematic view of the vertical air conditioner indoor unit when the baffle directs the air flow to the right; Figure 5 is Figure 2 A schematic view of the vertical air conditioner indoor unit when the baffle is in the closed state.

[0038] As Figures 1 to 5 As shown, the vertical air conditioner indoor unit of the embodiment of the present application can generally include a shell 10 and two micro baffles 31, 32.

[0039] The shell 10 defines an air duct 18 therein, which has an air outlet 12 for blowing air flow inside the shell 10. When the air conditioner is in the cooling mode, the air flow of the air outlet 12 is cold air; when the air conditioner is in the heating mode, the air flow of the air outlet 12 is hot air. Of course, if the air conditioner has additional adjustment functions such as purification, fresh air, etc., the air flow of the air outlet 12 can also include adjustment air flow such as purification air flow, fresh air flow, etc.

[0040] Specifically, as Figure 2 shown, the shell 10 defines an accommodation space for accommodating the main components of the vertical air conditioner indoor unit, including a fan 70, an indoor heat exchanger 60, a controller, etc. The rear part of the shell 10 can be provided with an air inlet 11. The indoor heat exchanger 60, the throttling device, and the compressor, the outdoor heat exchanger, and other refrigeration elements provided in the air conditioner outdoor unit are connected by pipelines to form a vapor compression refrigeration cycle system. In the cooling mode, the indoor heat exchanger 60 is an evaporator. In the heating mode, the indoor heat exchanger 60 is a condenser. Under the action of the fan 70, indoor air enters the inside of the shell 10 through the air inlet 11, completes forced convection heat exchange with the indoor heat exchanger 60, forms a heat exchange air flow, and flows out from the air outlet 12 under the guidance of the air duct 18. The shell 10 as a whole can be a vertical column, and its cross section can be square, rectangular, cylindrical, oval, or other shapes.

[0041] The two micro baffles 31, 32 are configured to disperse the air flow penetrating therethrough, so that the air flow is no longer strong and blows on the human body, which does not make the human body have too strong wind feeling, making the human body more comfortable.

[0042] The two micro baffles 31, 32 are vertically erected in front of the shell 10 along the transverse direction of the shell 10. The transverse direction of the shell 10 has been indicated in the figure, and when a human body faces the front side of the shell 10, the left-right direction of the human body is equivalent to the transverse direction of the shell 10. The two micro baffles 31, 32 form an air outlet interval 300 opposite to the air outlet 12 therebetween. That is, the two micro baffles 31, 32 do not contact and have a certain distance therebetween, forming an air outlet interval 300, i.e. Figure 2B1-B2. This allows the airflow from the outlet 12 to flow forward through the outlet gap 300 and into the indoor environment. Furthermore, each micro-air vane 31, 32 forms a side flow channel 310, 320 communicating with the outlet 12 between itself and the housing 10. During the forward flow of the airflow from the outlet 12, if it turns left or right before reaching the outlet gap 300, it can enter a side flow channel 310, 320, then penetrate the micro-air vanes 31, 32, be dispersed by the micro-air vanes 31, 32, and finally reach the indoor environment.

[0043] The vertical air conditioner indoor unit of this invention is configured to selectively blow the airflow from the air outlet 12 outward through one or more of the air outlet interval 300 and the two micro-wind vanes 31 and 32 to form multiple air outlet modes. The controller of the vertical air conditioner indoor unit can automatically adjust the air outlet mode according to the detection parameters or adjust the air outlet mode after receiving the user's operation command. The specific air outlet mode may include, but is not limited to, the following situations.

[0044] (1) As Figure 2 As shown, the airflow is simultaneously blown out through the air outlet interval 300 and the two micro-air panels 31 and 32, so that the airflow is smoothest and the air volume is the largest, delivering air to the entire area of ​​the front left, middle and right sides of the housing 10.

[0045] (2) Figure 3 As shown, the airflow is mainly blown out through the micro-air panel 31 on the left (a small portion of the airflow is also allowed to be blown out through the air outlet interval 300), and the air is delivered to the left front area of ​​the housing 10.

[0046] (3) Figure 4 As shown, the airflow is mainly blown out through the micro-air panel 32 on the right side (a small portion of the airflow is also allowed to be blown out through the air outlet interval 300), and the air is delivered to the right side area in front of the housing 10.

[0047] (4) Figure 5 As shown, the airflow is blown out through two micro-air panels 31 and 32, with no airflow at an air outlet interval of 300, achieving a micro-wind effect with maximum airflow, and air is supplied to the left and right sides in front of the housing 10, while no air is supplied to the middle area.

[0048] (5) In embodiments not shown in the figure, the airflow can also be blown out simultaneously through the left micro air plate 31 and the air outlet interval 300, or the airflow can be blown out simultaneously through the right micro air plate 32 and the air outlet interval 300. This will not be elaborated here.

[0049] The indoor unit of the vertical air conditioner of the embodiments of the present application can meet the micro wind function and the partitioned air supply function, and meet various air supply requirements of users. In addition, the micro wind function is realized by adding two micro wind plates 31 and 32 outside the shell 10, and the structure of the indoor unit of the vertical air conditioner is changed little, especially the internal structure of the shell 10 does not need to be changed, which is convenient for mass production.

[0050] In some embodiments, the indoor unit of the vertical air conditioner further comprises a baffle 20. The baffle 20 is rotatably arranged in front of the air outlet 12 about a vertical axis, and is used to guide the air flow of the air outlet 12 to any one of the side flow channels 310 and 320 or to guide the air flow to blow out from the air outlet interval 300. For example Figure 2 As shown, when the plate body of the baffle 20 extends in the front-rear direction, the air outlet interval 300 can be opened, and the air flow is guided forward. As shown Figure 3 As shown, when the inner side of the baffle 20 faces the left rear, the air flow is guided to the left side, flows to the left side flow channel 310, and then penetrates the left micro wind plate 31. As shown Figure 4 As shown, when the inner side of the baffle 20 faces the right rear, the air flow is guided to the right side, flows to the right side flow channel 320, and then penetrates the right micro wind plate 32. As shown Figure 5 As shown, when the inner side of the baffle 20 faces the rear, after the air flow reaches the inner side of the baffle 20, the air flow is turned to flow to the left and right sides, respectively enters the left and right side flow channels 310 and 320, and then penetrates the left and right micro wind plates 31 and 32.

[0051] In some embodiments, the baffle 20 is configured to be rotatable to a closed position for blocking the air outlet interval 300, as shown Figure 5 In this way, after the air flow reaches the inner side of the baffle 20, all the air flow is turned to flow to the left and right sides, respectively enters the left and right side flow channels 310 and 320, and then penetrates the left and right micro wind plates 31 and 32, so that all the air flow is micro wind flow, and the air volume is larger. In the shutdown state, the baffle 20 can be in the closed position, so that the appearance of the indoor unit of the vertical air conditioner in the shutdown state is more beautiful.

[0052] In some embodiments, as shown Figure 2 The indoor unit of the vertical air conditioner further comprises a vertical swing vane 50, which is rotatably arranged in the air duct 18 about a vertical axis to guide the lateral air outlet angle of the air flow. When the baffle 20 is in different positions, the vertical swing vane 50 can be used for air swing to adjust the flow distribution of the air outlet 12 in the left-right direction, so as to realize more rich adjustment functions. For example Figure 2 and Figure 5As shown, when both the left and right micro-ventilation panels 31 and 32 can discharge air, if the vertical oscillating blade 50 is directed to the left, the air discharge volume of the left micro-ventilation panel 31 will be greater, and if the vertical oscillating blade 50 is directed to the right, the air discharge volume of the right micro-ventilation panel 32 will be greater.

[0053] In some embodiments, such as Figure 2 As shown, the air outlet directions of the two micro-air panels 31 and 32 can be directed diagonally forward and far apart from each other, so that the left micro-air panel 31 can send air to the left front and the right micro-air panel 32 can send air to the right front, thus expanding the air outlet angle range of the vertical air conditioner indoor unit, so that when the two micro-air panels 31 and 32 send air out at the same time, the two airflows on the left and right sides can diffuse laterally at a larger angle.

[0054] In some embodiments, such as Figure 2 As shown, the side of each micro-air vane 31, 32 closest to the front lateral edge of the housing 10 is designated as the first side, and the side closest to the lateral center of the housing 10 is designated as the second side. In the figure, the first side of the left micro-air vane 31, 32 is designated as A1, and the second side as B1. The first side of the right micro-air vane 31, 32 is designated as A2, and the second side as B2. Each micro-air vane 31, 32 gradually moves away from the front of the housing 10 in the direction from the first side to the second side. In other words, the second side of each micro-air vane 31, 32 is further forward than the first side. This tilts both micro-air vanes 31, 32, facilitating the left micro-air vane 31 to deliver air to the left front and the right micro-air vane 32 to the right front, thus expanding the air outlet angle range of the vertical air conditioner indoor unit. This allows the two airflows on the left and right sides to diffuse laterally at a greater angle when both micro-air vanes 31, 32 are discharging air simultaneously.

[0055] Furthermore, each micro-air plate 31, 32 can be curved with its convex side facing forward to further enhance the divergence of the air delivery direction.

[0056] Furthermore, the first side of each micro-air panel 31, 32 can be placed against the housing 10, and the second side can be spaced from the front surface of the housing 10 to form side flow channels 310, 320. This not only achieves the installation and fixation of the micro-air panels 31, 32 to the housing 10, but also makes the connection and transition between the micro-air panels 31, 32 and the housing 10 smoother and more natural, avoiding the appearance of the housing 10 being abrupt due to the addition of the micro-air panels 31, 32.

[0057] In some embodiments, such as Figure 2As shown, each of the micro-ducts 31, 32 can be in a grid structure. Specifically, the grid can be a pure vertical grid, i.e., comprising a plurality of vertical grid bars arranged horizontally. Or the grid can be a pure horizontal grid, i.e., comprising a plurality of horizontal grid bars arranged vertically. Or, the grid can be a mesh grid, i.e., comprising a plurality of vertical grid bars and a plurality of horizontal grid bars arranged in a cross manner, forming a plurality of mesh holes arranged in a matrix manner. Of course, the grid bars can also be in other shapes and other arrangements.

[0058] Further, the grid of the two micro-ducts 31, 32 can be of different densities, so that the two have different air permeability. It can be understood that the higher the grid density, the smaller the hole, and the worse the air permeability. Conversely, the lower the grid density, the larger the hole, and the better the air permeability. In this way, the air volume of the left and right sides of the vertical air conditioner indoor unit is different, realizing the effect of different air supply on the left and right sides.

[0059] In other embodiments, the micro-ducts 31, 32 can be plate bodies provided with a plurality of micro-holes. The micro-holes are through holes penetrating the plate body to allow air flow to pass through. They can be round holes, square holes, oval holes or other shaped holes, which are not limited here. Or, the micro-ducts can also comprise a frame and a wind-permeable piece mounted on the frame, which can be a wind-permeable net made of non-metallic material, which can both permeate wind and clean and filter air flow.

[0060] In the description of the embodiments, the description of the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0061] So far, those skilled in the art should realize that although the present application has been shown and described in detail in the above embodiments, many other variants or modifications in accordance with the principles of the present application can be directly determined or deduced from the disclosure of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and recognized as covering all these other variants or modifications.
