TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to a cabinet type air conditioner. BACKGROUND

[0002] In order to reduce the indoor space occupied by the cabinet type air conditioner and meet the user's requirement for the appearance of indoor soft decoration, some users choose to install the cabinet type air conditioner in a cabinet. Due to the limitation of the form of the air duct of the conventional cabinet type air conditioner, air is usually taken in from the rear side of the cabinet type air conditioner and taken out from the front side or the left and right sides of the cabinet type air conditioner. When the traditional cabinet type air conditioner is installed in the cabinet, the air inlet is blocked, resulting in a significant reduction in the air supply and poor cooling and heating effects. CONTENT OF THE UTILITY MODEL

[0003] The present application aims to at least solve one of the above technical problems in the prior art to some extent. To this end, the present application provides a cabinet type air conditioner which can improve the problem of reduced air supply when the cabinet type air conditioner is installed in a cabinet.

[0004] The cabinet type air conditioner according to the embodiments of the present application comprises a casing, and the casing has a containing cavity therein. The casing can protect the components (such as heat exchangers, heat exchange fans, etc.) in the containing cavity, thereby reducing the damage probability of the components in the containing cavity.

[0005] The cabinet type air conditioner further comprises a heat exchanger arranged in the containing cavity. The heat exchanger is configured to exchange heat between indoor air and refrigerant transmitted in the heat exchanger.

[0006] The cabinet type air conditioner further comprises a heat exchange fan arranged in the containing cavity. The heat exchange fan is configured to suck indoor air into the cabinet type air conditioner and send the indoor air exchanged with the heat exchanger to the indoor space, and the heat exchange fan provides power for the flow of the indoor air.

[0007] The casing comprises a first side plate and a second side plate connected to each other. When the cabinet type air conditioner is installed in the cabinet, the first side plate and the second side plate are hidden.

[0008] The casing further comprises an air inlet panel provided with an air inlet opening, the air inlet opening being communicated between the containing cavity and the external environment for introducing air in the external environment into the containing cavity, and the heat exchanger is located between the air inlet opening and the heat exchange fan. When the cabinet type air conditioner is installed in the cabinet, the air inlet panel is exposed, which facilitates air intake at the air inlet opening and is beneficial to improve the air intake amount.

[0009] The shell further comprises an air outlet panel, and an air outlet is arranged on the air outlet panel, the air outlet being communicated with the accommodating cavity and the external environment to discharge air in the accommodating cavity to the external environment. When the cabinet type air conditioner is installed in the cabinet, the air outlet panel is exposed, air outlet at the air outlet is facilitated, and the air outlet amount is improved.

[0010] One of the air inlet panel and the air outlet panel is connected with the first side plate, and the other is connected with the second side plate.

[0011] According to the cabinet type air conditioner, the air inlet panel and the air outlet panel are arranged adjacent to each other when the cabinet type air conditioner is installed in the cabinet, the air inlet panel and the air outlet panel can be used as exposed panels, the problem that the air supply amount is reduced when the cabinet type air conditioner is installed in the cabinet is solved, and the heat exchange effect on air in the room is improved.

[0012] According to some embodiments of the present application, the angle between the air inlet panel and the air outlet panel is α, and α satisfies: α≥90° and α<180°.

[0013] By setting α≥90°, the distance between the air inlet and the air outlet in the accommodating cavity is far, the contact time of indoor air with the heat exchanger after the indoor air enters the accommodating cavity from the air inlet is long, and then the indoor air is blown out from the air outlet, so that the air outlet temperature at the air outlet can quickly meet the required temperature of the user, and the energy consumption of the cabinet type air conditioner is saved.

[0014] By setting α<180°, the air inlet flow and the air outlet flow are far away from each other in the external environment, the air inlet flow and the air outlet flow are not easy to cross and interfere with each other, air flow short circuit phenomenon is not easy to occur at the air inlet and the air outlet, the heat exchange effect is not affected, and the characteristics of the cross-flow air duct in the accommodating cavity are fully utilized to realize horizontal flow circulation of air flow.

[0015] According to some embodiments of the present application, α satisfies: α≤150°. Thus, the distance between the air inlet flow and the air outlet flow in the external environment is further increased, the air inlet flow and the air outlet flow are more difficult to cross, air flow short circuit phenomenon is more difficult to occur at the air inlet and the air outlet, and the heat exchange effect on air in the room is further improved.

[0016] According to some embodiments of the present application, α satisfies: α≥135°. Thus, the distance between the air inlet and the air outlet in the accommodating cavity is further increased, the contact time of indoor air with the heat exchanger after the indoor air enters the accommodating cavity from the air inlet is further increased, and then the indoor air is blown out from the air outlet, so that the air outlet temperature at the air outlet can more quickly meet the required temperature of the user, and the energy consumption of the cabinet type air conditioner is more saved.

[0017] According to some embodiments of the present application, the cabinet-type air conditioner further comprises a volute tongue, which is arranged in the accommodating cavity, and the volute tongue comprises a first volute tongue segment, which is used for surrounding a volute air duct.

[0018] The volute tongue further comprises a first outwardly expanded segment, which is connected with the first volute tongue segment and is used for surrounding the volute air duct.

[0019] The volute tongue further comprises a second volute tongue segment, which is at least partially surrounded by the first volute tongue segment and is configured as an arc-shaped plate, and the second volute tongue segment is used for surrounding the volute air duct.

[0020] The volute tongue further comprises a second outwardly expanded segment, which is connected with the second volute tongue segment and is used for surrounding the volute air duct.

[0021] The first volute tongue segment and the first outwardly expanded segment, and the second volute tongue segment and the second outwardly expanded segment form the volute air duct therebetween, the first volute tongue segment and the second volute tongue segment are close to the air inlet, the first outwardly expanded segment and the second outwardly expanded segment are close to the air outlet, and the flow area of the first outwardly expanded segment and the second outwardly expanded segment towards the air inlet is smaller than the flow area of the first outwardly expanded segment and the second outwardly expanded segment towards the air outlet. Thus, the air outlet speed at the air outlet is reduced, and the impact of the air blown out at the air outlet on the user is reduced.

[0022] The heat exchange fan is a cross-flow fan and is rotatably arranged between the first volute tongue segment and the second volute tongue segment, in a plane perpendicular to the height direction of the cabinet, the connection point of the first volute tongue segment and the first outwardly expanded segment is Q1, the connection point of the second volute tongue segment and the second outwardly expanded segment is Q2, and the center point of the heat exchange fan is Q3, and the included angle between the line segment Q1Q3 and the line segment Q1Q2 is obtuse.

[0023] Compared with the scheme in which the air inlet panel and the air outlet panel are arranged opposite to each other, in the present application, the air inlet panel and the air outlet panel are arranged adjacent to each other, β is set as an obtuse angle, the air inlet amount of the volute air duct can be ensured to be large, if the air inlet panel is arranged at a position opposite to the air outlet panel, the heat exchange fan needs to be moved towards the air inlet panel, which will necessarily cause the included angle between the line segment Q1Q3 and the line segment Q1Q2 to become an acute angle, therefore, in the present application, the air inlet panel and the air outlet panel are arranged adjacent to each other, the included angle between the line segment Q1Q3 and the line segment Q1Q2 is obtuse, and the air inlet amount of the volute air duct can still be ensured to be large.

[0024] According to some embodiments of the present application, the cabinet-type air conditioner further comprises an air inlet grille, which is mounted on the air inlet panel and arranged at the air inlet opening. The air inlet grille has a plurality of grille holes, which are in communication with the air inlet opening. The air inlet grille can shield a part of the air inlet opening, thereby preventing sundries and small animals from entering the accommodating cavity through the air inlet opening. The grille holes enable the accommodating cavity to be in communication with the external environment at the air inlet opening.

[0025] According to some embodiments of the present application, the air inlet grille comprises grille bars, which are rotatable to adjust the air inlet direction at the air inlet opening, thereby meeting the adjustment requirements of users for different air inlet directions.

[0026] According to some embodiments of the present application, the grille bars comprise first grille bars and second grille bars. The first grille bars extend in a first direction, and the second grille bars extend in a second direction. The first direction is different from the second direction. By rotating the first grille bars and the second grille bars, the air inlet direction can be adjusted in multiple directions.

[0027] According to some embodiments of the present application, the cabinet-type air conditioner further comprises one or more air deflector plates, which are mounted on the air outlet panel and swingably arranged at the air outlet opening to adjust the air outlet direction at the air outlet opening, thereby meeting the adjustment requirements of users for different air outlet directions. For example, the air outlet direction at the air outlet opening can be adjusted to directly blow air to the user. When the cabinet-type air conditioner is in cooling mode, the air outlet direction at the air outlet opening can be adjusted to blow air upward, so that the cold air blown upward can sink from top to bottom, thereby bringing the user a showering air experience. When the cabinet-type air conditioner is in heating mode, the air outlet direction at the air outlet opening can be adjusted to blow air downward, so that the hot air blown downward can rise from bottom to top, thereby passing through the user.

[0028] According to some embodiments of the present application, the air deflector plates extend in the height direction of the cabinet-type air conditioner. In this way, when air is blown outward from both sides of the air deflector plates, a continuous air flow can be formed in the height direction of the cabinet-type air conditioner.

[0029] According to some embodiments of the present application, the cabinet-type air conditioner further comprises a volute tongue, which has a volute tongue air duct. The air inlet end of the volute tongue air duct faces the air inlet opening, and the air outlet end of the volute tongue air duct faces the air outlet opening. The heat exchange fan is rotatably arranged at the air inlet end of the volute tongue air duct. The included angle between the normal line of the air inlet opening and the normal line of the air inlet end of the volute tongue air duct is not greater than 30°.

[0030] Compared with a conventional air duct, the cabinet air conditioner of the application makes the air inlet more smooth, the airflow enters the accommodating cavity through the air inlet, the normal line of the air inlet is F1, the normal line of the air inlet end port of the volute tongue air duct is F2, the smaller the included angle between F1 and F2, the smaller the airflow flow resistance, and the more smooth the air inlet, the volute tongue structure of the cabinet air conditioner of the application fully utilizes the shape characteristics of the cabinet, and the air inlet is more smooth than that of the conventional air conditioner.

[0031] Additional aspects and advantages of the application will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following description and drawings. BRIEF DESCRIPTION OF DRAWINGS

Detailed Implementation

[0047] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0048] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] To reduce the space occupied by floor-standing air conditioners and meet users' aesthetic requirements for interior decoration, some users choose to install floor-standing air conditioners inside cabinets. Due to the limitations of conventional floor-standing air conditioner ductwork, air typically enters from the rear and exits from the front or sides. When traditional floor-standing air conditioners are installed inside cabinets, the air intake is blocked, resulting in a significant reduction in airflow and poor cooling and heating performance. If both the air intake and exhaust vents are placed directly on the front panel, airflow short-circuiting can easily occur at the intake and exhaust points.

[0050] To solve the above problems, some embodiments of the utility model provide a kind of vertical cabinet type air conditioner 10, can improve the problem that vertical cabinet type air conditioner 10 is installed in vertical cabinet 20, and air supply amount is reduced, and air inlet 41 and outlet 51 at the airflow short circuit problem of even improvement and avoidance.

[0051] The vertical cabinet type air conditioner 10 according to the embodiments of the present application is described in detail below. Figures 1-13 The vertical cabinet type air conditioner 10 according to the embodiments of the present application is described in detail below.

[0052] Referring to Figures 1-11 As shown in the drawings, the vertical cabinet type air conditioner 10 according to the embodiments of the present application includes a cabinet 1, and the cabinet 1 has a receiving cavity 13 therein. The cabinet 1 can protect the components (such as the heat exchanger 2 and the heat exchange fan 3 mentioned below) in the receiving cavity 13, thereby reducing the damage probability of the components in the receiving cavity 13.

[0053] Referring to Figures 3-4 , Figure 7 , Figures 10-11 As shown in the drawings, the vertical cabinet type air conditioner 10 further includes a heat exchanger 2, and the heat exchanger 2 is arranged in the receiving cavity 13. The heat exchanger 2 is configured to exchange heat between indoor air and refrigerant transmitted in the heat exchanger 2.

[0054] In some embodiments, the heat exchanger 2 can include heat exchange fins to expand the contact area between indoor air and the refrigerant transmitted in the heat exchanger 2, thereby improving the heat exchange efficiency between indoor air and the refrigerant.

[0055] Referring to Figures 3-4 , Figure 7 , Figures 10-11 As shown in the drawings, the vertical cabinet type air conditioner 10 further includes a heat exchange fan 3, and the heat exchange fan 3 is arranged in the receiving cavity 13. The heat exchange fan 3 is configured to suck indoor air into the vertical cabinet type air conditioner 10 and send the indoor air exchanged with the heat exchanger 2 to the indoor space, and the heat exchange fan 3 provides power for the flow of indoor air. Specifically, the rotation of the heat exchange fan 3 is driven by a motor, and the vertical cabinet type air conditioner 10 further includes a control device, and the control device is connected to the motor driving the rotation of the heat exchange fan 3 through a data line to transmit communication information.

[0056] Referring to Figure 1 , Figures 3-5 , Figures 7-11 As shown in the drawings, the cabinet 1 includes a first side plate 11 and a second side plate 12, and the first side plate 11 and the second side plate 12 are connected. When the vertical cabinet type air conditioner 10 is installed in the vertical cabinet 20, the first side plate 11 and the second side plate 12 are used as a hidden plate.

[0057] In some embodiments, the included angle between the first side plate 11 and the second side plate 12 is not 0° or 180°, for example, the included angle between the first side plate 11 and the second side plate 12 can be an acute angle, a right angle or an obtuse angle.

[0058] Referring to Figures 1-11 As shown in FIG. 1, the cabinet 1 further comprises an air inlet panel 4, the air inlet panel 4 is provided with an air inlet 41, the air inlet 41 is communicated between the accommodating cavity 13 and the external environment for introducing the air of the external environment into the accommodating cavity 13, and the heat exchanger 2 is located between the air inlet 41 and the heat exchange fan 3. The heat exchange fan 3 provides power for the flow of indoor air, and drives the indoor air to enter the accommodating cavity 13 from the air inlet 41. After the indoor air enters the accommodating cavity 13 from the air inlet 41, the indoor air exchanges heat with the heat exchanger 2, and the heat exchange fan 3 further drives the indoor air after exchanging heat with the heat exchanger 2 to be sent to the indoor.

[0059] When the floor standing air conditioner 10 cools, the temperature of the indoor air entering the accommodating cavity 13 from the air inlet 41 is higher than the temperature of the heat exchanger 2, and the heat of the indoor air is transferred to the heat exchanger 2, so that the indoor air is cooled, and this part of air can reduce the indoor temperature after entering the indoor; when the floor standing air conditioner 10 heats, the temperature of the indoor air entering the accommodating cavity 13 from the air inlet 41 is lower than the temperature of the heat exchanger 2, and the indoor air absorbs heat from the heat exchanger 2, so that the indoor air is heated, and this part of air can increase the indoor temperature after entering the indoor.

[0060] Referring to Figures 1-11 As shown in FIG. 1, the cabinet 1 further comprises an air outlet panel 5, the air outlet panel 5 is provided with an air outlet 51, the air outlet 51 is communicated between the accommodating cavity 13 and the external environment for discharging the air in the accommodating cavity 13 to the external environment.

[0061] Specifically, when the floor standing air conditioner 10 is an indoor unit, the "external environment" referred to herein is the indoor. The heat exchange fan 3 drives the indoor air in the accommodating cavity 13 after exchanging heat with the heat exchanger 2 to be sent to the indoor through the air outlet 51. The air outlet 51 and the air inlet 41 are different ports, so as to avoid interference between the air inlet and the air outlet.

[0062] Among them, one of the air inlet panel 4 and the air outlet panel 5 is connected with the first side plate 11, and the other is connected with the second side plate 12, the air inlet panel 4 and the air outlet panel 5 are adjacent, and the air inlet panel 4 and the air outlet panel 5 are connected.

[0063] For example, referring to Figure 1 , Figure 3 , Figure 5 , Figures 7-8 , Figures 10-11 As shown in FIG. 1, the air inlet panel 4 is connected with the first side plate 11, and the air outlet panel 5 is connected with the second side plate 12.

[0064] Referring to Figure 4 , Figure 9 As shown in FIG. 1, the air inlet panel 4 is connected with the second side plate 12, and the air outlet panel 5 is connected with the first side plate 11.

[0065] In some embodiments, the first side plate 11, the second side plate 12, the air inlet panel 4 and the air outlet panel 5 are all flat plates, and the first side plate 11, the second side plate 12, the air inlet panel 4 and the air outlet panel 5 form a quadrilateral in a plane perpendicular to the height direction of the cabinet 1. The quadrilateral can be a square, a rectangle, a trapezoid, etc. As shown in Figures 3-4 , Figure 10 , the quadrilateral formed by the first side plate 11, the second side plate 12, the air inlet panel 4 and the air outlet panel 5 is a square; as shown in Figure 7 , Figure 11 , the quadrilateral formed by the first side plate 11, the second side plate 12, the air inlet panel 4 and the air outlet panel 5 is a trapezoid.

[0066] Referring to Figures 8-9 , when the floor standing air conditioner 10 is installed in the cabinet 20, the cabinet 20 includes a first cabinet plate 201, a second cabinet plate 202, a third cabinet plate 203 and a fourth cabinet plate 204. The first cabinet plate 201 and the second cabinet plate 202 are connected, the third cabinet plate 203 and the fourth cabinet plate 204 are connected, and the third cabinet plate 203 and the fourth cabinet plate 204 are located at a corner of a wall. The recessed area is surrounded by the first cabinet plate 201 and the second cabinet plate 202. The first side plate 11 is arranged opposite to the first cabinet plate 201, and the second side plate 12 is arranged opposite to the second cabinet plate 202. The shape characteristics of the cabinet 20 located at the corner of the wall are reasonably utilized to realize that the floor standing air conditioner 10 is completely embedded in the cabinet or the wall, and no separate space is occupied.

[0067] When the floor standing air conditioner 10 is installed in the cabinet 20, the air inlet panel 4 is exposed, which facilitates air inlet at the air inlet port 41 and is beneficial to improve the air inlet amount. The air outlet panel 5 is exposed, which facilitates air outlet at the air outlet port 51 and is beneficial to improve the air outlet amount.

[0068] The conventional floor standing air conditioner is air-in at the rear side and air-out at the front side, and cannot realize the embedded effect. The floor standing air conditioner 10 of the present application reasonably utilizes the shape characteristics of the cabinet 20 located at the corner of the wall, embeds the air conditioner body in the cabinet 20, and combines the various arrangements of the air inlet panel 4 and the air outlet panel 5 to form an embedded air conditioner with invisible appearance.

[0069] In some embodiments of the present application, as shown in Figures 8-9 , the first side plate 11 and the first cabinet plate 201 have a gap L1, and L1>0. Thus, the first side plate 11 and the first cabinet plate 201 can be prevented from interfering when the floor standing air conditioner 10 is installed in the cabinet 20.

[0070] In some embodiments of the present application, as shown in Figures 8-9 , the second side plate 12 and the second cabinet plate 202 have a gap L2, and L2>0. Thus, the second side plate 12 and the second cabinet plate 202 can be prevented from interfering when the floor standing air conditioner 10 is installed in the cabinet 20.

[0071] When the cabinet air conditioner 10 is installed in the cabinet 20, the first side plate 11 and the second side plate 12 are used as the hidden plates, and the air inlet panel 4 and the air outlet panel 5 are arranged adjacent to each other, so that the air inlet panel 4 and the air outlet panel 5 can be used as the exposed panels, the problem that the air supply amount is reduced when the cabinet air conditioner 10 is installed in the cabinet 20 can be solved, and the heat exchange effect on the air in the room is improved.

[0072] In some embodiments of the present application, as shown in Figures 3-4 , Figure 7 , the angle between the air inlet panel 4 and the air outlet panel 5 is α, and α satisfies: α≥90°, α<180°. In other words, the included angle between the air inlet panel 4 and the air outlet panel 5 is a right angle or an obtuse angle.

[0073] When α<90°, the distance between the air inlet 41 and the air outlet 51 in the accommodating cavity 13 is relatively short, the indoor air entering the accommodating cavity 13 from the air inlet 41 has a relatively short contact time with the heat exchanger 2, and then is blown out from the air outlet 51, which causes the air outlet temperature at the air outlet 51 to be difficult to meet the required temperature of the user, and causes the energy consumption of the cabinet air conditioner 10 to increase.

[0074] By setting α≥90°, the distance between the air inlet 41 and the air outlet 51 in the accommodating cavity 13 is relatively far, the indoor air entering the accommodating cavity 13 from the air inlet 41 has a relatively long contact time with the heat exchanger 2, and then is blown out from the air outlet 51, so that the air outlet temperature at the air outlet 51 can quickly meet the required temperature of the user, which is beneficial to save the energy consumption of the cabinet air conditioner 10.

[0075] For example, α can be 90°, 100°, 110°, 120°, 125°, etc.

[0076] In the example of Figures 3-4 , α is 90°, and the air inlet panel 4 is perpendicular to the air outlet panel 5.

[0077] When α≥180°, the air inlet flow of the air inlet 41 and the air outlet flow of the air outlet 51 are easy to cross in the external environment, which causes the air flow short circuit phenomenon to easily occur at the air inlet 41 and the air outlet 51.

[0078] By setting α<180°, the air inlet flow of the air inlet 41 and the air outlet flow of the air outlet 51 are far away from each other in the external environment, and are not easy to cross, so as not to interfere with each other, the air flow short circuit phenomenon is not easy to occur at the air inlet 41 and the air outlet 51, the heat exchange effect is not affected, the characteristics of the cross-flow air duct in the accommodating cavity 13 can be fully utilized, and the horizontal direction flow circulation of the air flow is realized.

[0079] For example, α can be 155°, 160°, 165°, 170°, etc.

[0080] It should be noted that the air inlet panel 4 can be flat or curved, and the air outlet panel 5 can be flat or curved.

[0081] When both the air inlet panel 4 and the air outlet panel 5 are flat, refer to Figures 3-4 , Figure 7 As shown, the angle between the air inlet panel 4 and the air outlet panel 5 is the included angle between the two planes.

[0082] When one of the air inlet panel 4 and the air outlet panel 5 is a flat surface and the other is a curved surface, the angle between the air inlet panel 4 and the air outlet panel 5 is: within the same horizontal plane, the angle between the tangent of the curved surface and the flat surface at the junction of the curved surface and the flat surface. For example... Figure 12 As shown, the air inlet panel 4 is a flat surface and the air outlet panel 5 is an arc surface. In the same horizontal plane, at the connection between the air outlet panel 5 and the air inlet panel 4, the angle between the tangent L1 of the air outlet panel 5 and the air inlet panel 4 is α.

[0083] When both the air inlet panel 4 and the air outlet panel 5 are curved surfaces, the angle between them is: the angle between the tangents of the two curved surfaces at their junction on the same horizontal plane. For example... Figure 13 As shown, both the air inlet panel 4 and the air outlet panel 5 are arc surfaces. In the same horizontal plane, at the connection between the air outlet panel 5 and the air inlet panel 4, the angle between the tangent line L2 of the air outlet panel 5 and the tangent line L3 of the air inlet panel 4 is α.

[0084] Reference Figures 8-9 As shown, to reduce the indoor space occupied by the floor-standing air conditioner 10, the floor-standing air conditioner 10 is installed in a floor-standing cabinet 20. The floor-standing cabinet 20 and the floor-standing air conditioner 10 together form a floor-standing air conditioning assembly 100. The floor-standing cabinet 20 includes a cabinet door 205 and also has a recessed area. The floor-standing air conditioner 10 is placed in the recessed area. One of the air inlet panel 4 and the air outlet panel 5 is flush with the cabinet door 205, while the other air inlet panel 4 and the air outlet panel 5 are away from the floor-standing cabinet 20. Both the air inlet panel 4 and the air outlet panel 5 are exposed panels, which prevents the floor-standing cabinet 20 from blocking the airflow at the air inlet 41 and the air outlet 51. The floor-standing air conditioner 10 has a large air volume and good cooling and heating effects.

[0085] For example, in Figure 8 In the example, the air inlet panel 4 is flush with the cabinet door 205, and the air outlet panel 5 is away from the cabinet 20.

[0086] For example, in Figure 9 In the example, the air outlet panel 5 is flush with the cabinet door 205, and the air inlet panel 4 is away from the cabinet 20.

[0087] The panel flush with the cabinet door 205 can be selected to have the same or similar appearance as the cabinet door 205, so that the cabinet air conditioner 10 has a similar appearance to the cabinet 20, forming a hidden embedded air conditioner.

[0088] Without affecting the performance of the air conditioner, the cabinet air conditioner 10 is embedded beside the cabinet 20 to form a cabinet air conditioner assembly 100, and the cross-flow air duct in the accommodation cavity 13 is used to achieve the embedded hidden effect of the air inlet and air outlet at a certain angle, without occupying independent space, and the demand of the user for appearance can be met to the greatest extent.

[0089] According to the cabinet air conditioner 10 installed in the cabinet 20, the air inlet panel 4 and the air outlet panel 5 are used as exposed panels, which can improve the problem that the air supply amount decreases when the cabinet air conditioner 10 is installed in the cabinet 20. By setting the included angle between the air inlet panel 4 and the air outlet panel 5 to be a right angle or an obtuse angle, the airflow short circuit problem at the air inlet 41 and the air outlet 51 can be improved or even avoided, and the heat exchange effect on the air in the room is improved.

[0090] In some embodiments of the present application, α satisfies: α≤150°. Thus, the distance between the air inlet 41 and the air outlet 51 in the external environment is further increased, and the air inlet 41 and the air outlet 51 are more difficult to cross, and the airflow short circuit phenomenon at the air inlet 41 and the air outlet 51 is further improved, and the heat exchange effect on the air in the room is further improved.

[0091] In some embodiments of the present application, α satisfies: α≥135°. Thus, the distance between the air inlet 41 and the air outlet 51 in the accommodation cavity 13 is further increased, and the contact time of the indoor air entering the accommodation cavity 13 from the air inlet 41 with the heat exchanger 2 is further increased, and then the air outlet 51 blows out, so that the air outlet temperature at the air outlet 51 can meet the required temperature of the user faster, and it is more beneficial to save the energy consumption of the cabinet air conditioner 10.

[0092] For example, α can be 135°, 140°, 145°, 150°, etc.

[0093] It should be noted that the first side plate 11 can be a plane or a circular arc surface, and the second side plate 12 can be a plane or a circular arc surface.

[0094] When one of the first side plate 11 and the second side plate 12 is a plane and the other is a circular arc surface, the angle between the first side plate 11 and the second side plate 12 is: in the same horizontal plane, the connection between the circular arc surface and the plane, and the included angle between the tangent line of the circular arc surface and the plane. Figure 12 The included angle between the air inlet panel 4 and the air outlet panel 5 is shown.

[0095] When the first side plate 11 and the second side plate 12 are both arc surfaces, the angle between the first side plate 11 and the second side plate 12 is the included angle between the tangent lines of the two arc surfaces at the connection of the two arc surfaces in the same horizontal plane. Figure 13 The angle between the air inlet panel 4 and the air outlet panel 5 is shown.

[0096] In some embodiments of the present application, with reference to Figures 10-11 As shown, the floor-standing air conditioner 10 further comprises a volute tongue 8, which is arranged in the accommodating cavity 13. The volute tongue 8 comprises a first volute tongue segment 81, which is configured as an arc plate. The first volute tongue segment 81 is used to surround the volute tongue air duct 80.

[0097] The volute tongue 8 further comprises a first outer expansion segment 83, which is connected with the first volute tongue segment 81. The first outer expansion segment 83 is used to surround the volute tongue air duct 80.

[0098] The volute tongue 8 further comprises a second volute tongue segment 82, which is configured as an arc plate. The second volute tongue segment 82 at least partially surrounds the first volute tongue segment 81. The second volute tongue segment 82 is used to surround the volute tongue air duct 80. The first volute tongue segment 81 is located on the side of the second volute tongue segment 82 close to the air inlet panel 4 and the air outlet panel 5.

[0099] The volute tongue 8 further comprises a second outer expansion segment 84, which is connected with the second volute tongue segment 82. The second outer expansion segment 84 is used to surround the volute tongue air duct 80.

[0100] The volute tongue air duct 80 is formed between the first volute tongue segment 81 and the first outer expansion segment 83, and between the second volute tongue segment 82 and the second outer expansion segment 84. The first volute tongue segment 81 and the second volute tongue segment 82 are close to the air inlet 41, and the first outer expansion segment 83 and the second outer expansion segment 84 are close to the air outlet 51. The flow area of the end of the first outer expansion segment 83 and the second outer expansion segment 84 facing the air inlet 41 is smaller than the flow area of the end of the first outer expansion segment 83 and the second outer expansion segment 84 facing the air outlet 51. This is beneficial to reduce the air outlet speed at the air outlet 51 and reduce the impact of the air blown out at the air outlet 51 on the user.

[0101] For example, in the direction from the air inlet 41 to the air outlet 51, the flow area of the air duct formed between the first outer expansion segment 83 and the second outer expansion segment 84 gradually increases, so that the air speed through the air duct between the first outer expansion segment 83 and the second outer expansion segment 84 gradually decreases in the direction from the air inlet 41 to the air outlet 51.

[0102] The volute tongue air duct 80 comprises a first air duct section and a second air duct section, the first air duct section is formed between the first volute tongue section 81 and the second volute tongue section 82, the second air duct section is formed between the first outer expansion section 83 and the second outer expansion section 84, the first air duct section is located at one end of the second air duct section facing the air inlet 41, and the heat exchange fan 3 is rotatably arranged in the first air duct section.

[0103] The heat exchange fan 3 is a cross-flow fan, and the heat exchange fan 3 is rotatably arranged between the first volute tongue section 81 and the second volute tongue section 82. In a plane perpendicular to the height direction of the cabinet 1, the connection point of the first volute tongue section 81 and the first outer expansion section 83 is Q1, the connection point of the second volute tongue section 82 and the second outer expansion section 84 is Q2, and the center point of the heat exchange fan 3 is Q3. The included angle between the line segment Q1Q3 and the line segment Q1Q2 is obtuse.

[0104] Referring to Figures 10-11 , the included angle between the line segment Q1Q3 and the line segment Q1Q2 is β, and 90°<β<180°. Compared with the scheme that the air inlet panel and the air outlet panel are arranged opposite to each other, in the present application, the air inlet panel 4 and the air outlet panel 5 are arranged adjacent to each other, the angle β is set to be obtuse, which can ensure that the air inlet amount of the volute tongue air duct 80 is large. If the air inlet panel is arranged at a position opposite to the air outlet panel, the heat exchange fan needs to move towards the air inlet panel 4, which may result in that the included angle between the line segment Q1Q3 and the line segment Q1Q2 becomes acute. Therefore, in the present application, the air inlet panel 4 and the air outlet panel 5 are arranged adjacent to each other, the included angle between the line segment Q1Q3 and the line segment Q1Q2 is obtuse, and the air inlet amount of the volute tongue air duct 80 can still be large.

[0105] For example, β can be 100°, 110°, 120°, 125°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, etc.

[0106] For example, in one example, β is 105°, which can ensure that the air inlet amount of the volute tongue air duct 80 is large.

[0107] In some embodiments of the present application, referring to Figures 1-7 , Figures 10-11 , the upright cabinet type air conditioner 10 further comprises an air inlet grille 6, the air inlet grille 6 is mounted on the air inlet panel 4, the air inlet grille 6 is arranged at the air inlet 41, the air inlet grille 6 has a plurality of grille holes, and the grille holes are in communication with the air inlet 41. The air inlet grille 6 can protect the air inlet 41 and shield a part of the air inlet 41, thereby preventing sundries, small animals, etc. from entering the containing cavity 13 through the air inlet 41. The arrangement of the grille holes enables the containing cavity 13 and the external environment to be in communication at the air inlet 41.

[0108] In some embodiments of the present application, the shape of the grid holes is arbitrary, for example, the grid holes can be strip holes, round holes, triangular holes, etc.

[0109] In some embodiments of the present application, the air inlet grille 6 comprises grille bars, which can be rotated to adjust the air inlet direction at the air inlet 41, so as to meet the user's adjustment demand for different air inlet directions.

[0110] In some embodiments of the present application, the grille bars comprise first grille bars and second grille bars, the first grille bars extend along a first direction, and the second grille bars extend along a second direction, the first direction being different from the second direction. By rotating the first grille bars and the second grille bars, multi-directional adjustment of the air inlet direction can be achieved.

[0111] For example, the first direction is the height direction of the cabinet air conditioner 10, and the second direction is the width direction of the cabinet air conditioner 10. Of course, the first direction and the second direction can also be other directions, for example, the first direction and the height direction of the cabinet air conditioner 10 have an acute angle, and the second direction and the width direction of the cabinet air conditioner 10 have an acute angle.

[0112] In some embodiments of the present application, as shown in Figures 1-7 , Figures 10-11 , the cabinet air conditioner 10 further comprises an air guide plate 7, which is installed on the air outlet panel 5 and is swingably arranged at the air outlet 51 to adjust the air outlet direction at the air outlet 51, so as to meet the user's adjustment demand for different air outlet directions. For example, the air outlet direction at the air outlet 51 can be adjusted to directly blow on the user; when the cabinet air conditioner 10 is cooling, the air outlet direction at the air outlet 51 can be adjusted to blow upward, so that the cold air blown upward can sink from top to bottom due to its heaviness, bringing the user a showering wind experience; when the cabinet air conditioner 10 is heating, the air outlet direction at the air outlet 51 can be adjusted to blow downward, so that the hot air blown downward can rise from bottom to top due to its lightness, passing through the user.

[0113] In some embodiments of the present application, the number of air guide plates 7 is one. In this way, the number of air guide plates 7 is small, the structure is simple, and it is beneficial to save costs.

[0114] In some embodiments of the present application, the number of air guide plates 7 is multiple. The mounting shafts of the multiple air guide plates 7 can be arranged in parallel, and the multiple air guide plates 7 can swing synchronously or asynchronously. The swinging of each air guide plate 7 can be manually operated or operated by a motor. As shown in Figures 1-7 , Figures 10-11 , the number of air guide plates 7 is five. In some embodiments not shown in the figure, the number of air guide plates 7 can also be two, three, six, etc.

[0115] In some embodiments of the present application, referring to FIG. 1, the air deflector 7 extends along the height direction of the cabinet air conditioner 10. In this way, when air is blown out from both sides of the air deflector 7, a continuous air flow can be formed in the height direction of the cabinet air conditioner 10. Figures 1-2 、 Figures 5-6 In some embodiments of the present application, referring to FIG. 1, the air deflector 7 extends along the height direction of the cabinet air conditioner 10. In this way, when air is blown out from both sides of the air deflector 7, a continuous air flow can be formed in the height direction of the cabinet air conditioner 10.

[0116] In some embodiments of the present application, referring to FIG. 1, the air deflector 7 extends along the height direction of the cabinet air conditioner 10. In this way, when air is blown out from both sides of the air deflector 7, a continuous air flow can be formed in the height direction of the cabinet air conditioner 10. Figures 10-11

[0117] Specifically, the normal line of the air inlet 41 is F1, the normal line of the air inlet end of the volute tongue air duct 80 is F2, and the included angle between F1 and F2 is not greater than 30°.

[0118] Compared with conventional air ducts, the cabinet air conditioner 10 of the present application makes the air inlet more smooth. The air flow enters the containing cavity 13 through the air inlet 41. The normal line of the air inlet end of the volute tongue air duct 80 is F2. The smaller the included angle between F1 and F2, the smaller the air flow resistance, and the more smooth the air inlet. The volute tongue 8 structure of the cabinet air conditioner 10 of the present application fully utilizes the shape characteristics of the cabinet 20, and the air inlet is more smooth than conventional air conditioners.

[0119] That is, the air inlet panel 4 is a flat panel, and the included angle between the port plane P2 of the air inlet end of the volute tongue air duct 80 and the plane P1 on which the air inlet panel 4 is located is not greater than 30°.
