Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a jet air duct air conditioner. Background Art

[0002] Air conditioning refers to equipment that uses artificial means to adjust and control the temperature, humidity, cleanliness, flow rate and other parameters of the ambient air in a building or structure.

[0003] Air conditioners can be roughly divided into two categories, one is split type, including indoor and outdoor units, and the other is integrated type, such as mobile air conditioners. The temperature control principle of air conditioners is basically to use the refrigerant to evaporate or condense under the action of the compressor, thereby causing the evaporation or condensation of the air to achieve the purpose of changing the temperature and humidity.

[0004] Whether it is a split type or an integrated air conditioner, the structure of the air guide plate at the air outlet is similar. Specifically, several plates are distributed parallel to each other and are rotatably connected to each plate by setting a connecting rod. In this way, by driving the connecting rod to move back and forth, the plates can be driven to swing back and forth synchronously as a whole, thereby realizing the control of the air outlet direction.

[0005] However, the existing wind guide plate structure has the following deficiencies in actual use: the plates of the existing wind guide plate structure rotate synchronously, so there is only a single wind direction that changes with the rotation of the plates, that is, only the direction in which the plates face is blown out, and no cold wind is blown out in the direction in which the plates do not face, resulting in poor indoor cooling effect. This deficiency is more obvious when the indoor temperature is higher. Therefore, in order to solve the above-mentioned deficiencies, the jet duct air conditioner of the present application is proposed. Utility Model Content

DETAILED DESCRIPTION

[0035] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show preferred embodiments of the present invention.

[0036] like Figures 1 to 4As shown, a jet duct air conditioner 10 includes a housing 100 and an air outlet assembly 200, the air outlet assembly 200 includes a plurality of air outlet members 210 distributed at intervals, the air outlet member 210 includes a wind housing 211, an air outlet ball 212, a connecting rod 213, a first driving member 214 and a second driving member 215, the wind housing 211 is arranged on the inner wall of the housing 100, a transfer air cavity 2111 is provided in the wind housing 211, a reversing hole 2112 connected to the transfer air cavity 2111 is provided on one side wall of the wind housing 211, the first driving member 214 is arranged on the wind housing 211, one end of the connecting rod 213 is connected to the transfer air cavity 2111, and the first driving member 214 is connected to the first driving member 214. The output shaft of the first driving member 214 is connected, and the other end of the connecting rod 213 is rotatably connected to the air outlet ball 212, and the air outlet ball 212 is located in the transfer air cavity 2111, and the outer wall of the air outlet ball 212 abuts against the inner wall of the reversing hole 2112, and the air outlet ball 212 is provided with an air inlet 2121 and an air outlet 2122 that are interconnected, and the air inlet 2121 is located in the transfer air cavity 2111, and the air outlet 2122 extends from the reversing hole 2112, and the second driving member 215 is arranged on the air outlet ball 212, and the output shaft of the second driving member 215 is connected to the connecting rod 213.

[0037] It should be noted that the air outlet assembly 200 includes a plurality of air outlet members 210 spaced apart on the housing 100. Each air outlet member 210 is used to eject cold air. Since each air outlet member 210 is an independent structure, its ejection direction is independent of each other. Therefore, compared with the existing air conditioner that uses an air guide plate to guide air, the jet duct air conditioner 10 of the present application can eject cold air in multiple directions at the same time, thereby improving the efficiency of indoor cooling. Specifically, the wind shell 211 is installed on the inner wall of the housing 100. A transfer air cavity 2111 is provided in the wind shell 211, and a reversing hole 2112 is also provided on one side wall. The reversing hole 2112 extends from the inner side of the housing 100 to the outside. Furthermore, the first drive member 214 is installed on the side surface of the wind shell 211 away from the reversing hole 2112. One end of the connecting rod 213 is fixedly connected to the output shaft of the first driving member 214, and the other end of the connecting rod 213 is rotatably connected to the air outlet ball 212. The outer wall of the air outlet ball 212 is in contact with the inner wall of the reversing hole 2112. In this way, when the first driving member 214 drives the connecting rod 213 to rotate, the air outlet ball 212 can be driven to rotate relative to the axis of the reversing hole 2112. Further, the air outlet ball 212 is provided with an air inlet 2121 and an air outlet 2122 that are interconnected, wherein the air inlet 2121 is located in the transfer air cavity 2111, and the air outlet 2122 extends from the reversing hole 2112. The second driving member 215 is fixedly mounted on the air outlet ball 212, and the output shaft of the second driving member 215 is connected to the connecting rod 213. In this way, when the second driving member 215 drives the connecting rod 213 to rotate, the air outlet ball 212 can also be driven to rotate relative to the connecting rod 213. The plane formed by the air outlet ball 212 rotating relative to the connecting rod 213 is coplanar with the axis of the connecting rod 213. In this way, the air outlet ball 212 is driven to rotate by the second driving member 215, so that the air outlet 2122 of the air outlet ball 212 can be deflected in the reversing hole 2112, and the air outlet ball 212 is driven to rotate relative to the axis of the connecting rod 213 by the first driving member 214 through the connecting rod 213, so that the air outlet 2122 of the air outlet ball 212 can be adjusted to any direction in the reversing hole 2112. In this way, compared with the air guide plate structure in the existing air conditioner, the air outlet direction of each air outlet member 210 of the present application can be set to any direction as needed, so the user can set it to different air outlet directions as needed, so that the indoor temperature can be reduced more quickly and the cooling efficiency can be improved.

[0038] like Figure 5 and Figure 6 As shown, in one embodiment, the connecting rod 213 includes a rod body 2131 and a cross pin 2132, the cross pin 2132 is rotatably set on the air outlet ball 212, the output shaft of the second driving member 215 is connected to the cross pin 2132, one end of the rod body 2131 is set on the cross pin 2132, and the end of the rod body 2131 away from the cross pin 2132 is connected to the first driving member 214.

[0039] It should be noted that the cross pin 2132 is installed in the air outlet ball 212 through a bearing, so that the cross pin 2132 can rotate relative to the air outlet ball 212. One end of the rod body 2131 is fixedly installed with the cross pin 2132, for example, the rod body 2131 and the cross pin 2132 are formed into an integrated structure by welding.

[0040] In one embodiment, the axis of the cross pin 2132 coincides with the center of the air outlet ball 212. In this way, one end of the rod body 2131 can rotate relative to the center of the air outlet ball 212, and when the second driving member 215 drives the air outlet ball 212 to rotate relative to the connecting rod 213, the outer wall of the air outlet ball 212 is always tightly fitted with the inner wall of the reversing hole 2112.

[0041] In one embodiment, in order to improve the air tightness between the outer wall of the air outlet ball 212 and the inner wall of the reversing hole 2112, a sealing ring is provided on the inner wall of the reversing hole 2112, and the sealing ring is fitted with the outer wall of the air outlet ball 212. In this way, the sealing ring is used to eliminate the gap between the air outlet ball 212 and the reversing hole 2112.

[0042] like Figure 7 As shown, in one embodiment, an air-avoiding groove 2123 is further provided on the air outlet ball 212 . The air-avoiding groove 2123 and the air inlet 2121 are independent of each other, and the second driving member 215 is disposed on the inner side wall of the air-avoiding groove 2123 .

[0043] It should be noted that the air outlet ball 212 is located in the transfer air cavity 2111. The first driving member 214 and the second driving member 215 cooperate with each other to change the direction of the air outlet 2122, so that the cold air in the transfer air cavity 2111 passes through the air inlet 2121 and is ejected from the air outlet 2122. In order to prevent the second driving member 215 from directly contacting the cold air, an air avoidance groove 2123 independent of the air inlet 2121 is opened on the air outlet ball 212, and then the second driving member 215 is installed on the inner wall of the air avoidance groove 2123.

[0044] Furthermore, in one embodiment, a cover is provided on the top of the air-avoiding groove 2123, and the cover is used to shield the second driving member 215. In this way, the cover and the inner wall of the air-avoiding groove 2123 form a closed space to prevent the second driving member 215 from directly contacting the cold air in the transfer air cavity 2111.

[0045] like Figure 6As shown, in one embodiment, the second driving member 215 includes a flipping motor 2151, a driving gear 2152 and a driven gear 2153, the flipping motor 2151 is arranged on the inner wall of the air avoidance groove 2123, the driving gear 2152 is arranged on the output shaft of the flipping motor 2151, the driven gear 2153 is arranged on the cross pin 2132, and the driven gear 2153 is meshed with the driving gear 2152.

[0046] In this way, when the driving gear 2152 is driven by the flip motor 2151 to rotate, the driving gear 2152 drives the driven gear 2153 to rotate, and the connecting rod 213 is rotated relative to the air outlet ball 212.

[0047] like Figure 2 As shown, in one embodiment, at least one air inlet pipe 216 is disposed on the air housing 211, and each air inlet pipe 216 is connected to the transfer air cavity 2111. Thus, after the cold air in the housing 100 enters the transfer air cavity 2111 through the air inlet pipe 216, it is adjusted in direction by the air outlet ball 212 and then ejected from the air outlet 2122.

[0048] like Figure 2 As shown, in one embodiment, the air housing 211 is further provided with a plurality of fixing ears 217, each of which is located on the outer side wall of the air housing 211. Thus, the air outlet member 210 is conveniently fixedly installed in the housing 100 through the fixing ears 217.

[0049] like Figure 8 As shown, in one embodiment, an evaporator 300 is disposed in the casing 100, and the evaporator 300 is used to separate the casing 100 into an air inlet area 110 and an air outlet area 120, each air outlet member 210 is located in the air outlet area 120, and an air intake grille 400 is disposed on the side wall of the casing 100 located in the air inlet area 110.

[0050] It should be noted that the outside air enters the air inlet area 110 through the air inlet grille 400, and then enters the air outlet area 120 after being cooled by the evaporator 300. Then, the air is ejected from different directions through the air outlet parts 210.

[0051] like Figure 8 As shown, in one embodiment, a fan 510 and a plurality of wind wheels 520 are further disposed in the casing 100. The fan 510 is disposed on the inner wall of the air inlet area 110. Each wind wheel 520 is rotatably disposed on the inner wall of the air inlet area 110. Each wind wheel 520 is connected to the output shaft of the fan 510, and each wind wheel 520 faces the evaporator 300.

[0052] In this way, the fan 510 drives the impeller 520 to rotate, driving the air entering from the air inlet grille 400 to pass through the evaporator 300 for cooling, and finally ejected from different directions through the air outlets 210. In this way, compared with the existing air conditioners, the cold air of the jet duct air conditioner 10 of the present application can be ejected from different directions, thereby improving the indoor cooling efficiency.

[0053] like Figure 1 , Fig. 9 and Fig.10 As shown, there are three different embodiments of the jet duct air conditioner 10 of the present application, wherein Figure 1 It is a six-hole jet duct air conditioner. Fig. 9 It is a six-hole jet cabinet air conditioner. Fig.10 It should be noted that the embodiments of the present application are for the purpose of facilitating a better understanding of the technical solution of the present application, and are not limited to the number of specific perforations (air outlets 210), so it can also be a two-hole jet duct air conditioner, or a two-hole jet cabinet air conditioner.

[0054] The above-described embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the utility model patent. The installation / fixing / setting mentioned in the utility model, unless otherwise specifically defined, can be understood to include but not be limited to locking and fixing with screws / screws and welding. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
