[0034] The present invention provides an air conditioning device 100.

[0035] In the embodiments of the present invention, the air conditioning device 100 can be, for example, a mobile air conditioner or an air conditioning device with a fresh air function. The air conditioning device 100 can introduce external air into the room and perform heat exchange with the heat exchanger 140. Next, please refer to Figures 1 to 4 and take the mobile air conditioner as an example to illustrate the present invention.

[0036] Attached Figure 1 is a perspective view of the three-dimensional structure of the air conditioning device 100 of the present invention. The external connection device is removed in the figure, so the air inlet 115 and the air outlet 117 are exposed. The air conditioning device 100 includes a housing 110, wherein the housing 110 includes an outer shell 111 and a chassis 113. The chassis 113 is connected to the lower end of the outer shell 111, and rollers 119 are installed below the chassis 113, so that the air conditioning device 100 can be moved more conveniently.

[0037] Figure 2 is a perspective view of the internal structure of the air conditioning device 100 after removing the outer shell 111. From Figure 2It can be observed that in the air conditioning device 100 of the present application, a middle partition component 120 is further provided inside the housing 111. The middle partition component 120 divides the space inside the housing 111 into an upper space and a lower space. A supply air volute component 130 is provided in the upper space. The supply air volute component 130 includes components such as an evaporator, a supply air volute, and a supply air impeller. The supply air volute component 130 is used to supply air to the room for temperature adjustment. Although the inlet and outlet structures corresponding to the supply air volute component 130 are not shown in the drawings, it can be understood that the inlet and outlet corresponding to the supply air volute component 130 can be opened on the side wall of the housing 111. Combining the attached Figure 4 , in the lower space, an exhaust air volute component and a compressor 170 are provided. The exhaust air volute component includes an exhaust air impeller 180 (as Figure 3 shown), an exhaust air volute cover 160, a heat exchanger 140 (condenser during refrigeration), a capacitor component, etc. The compressor 170 drives the refrigerant to circulate in the evaporator and the condenser. The exhaust air volute component is used to introduce external air into the room during the temperature adjustment process of the air conditioning device 100 and perform heat exchange with the heat exchanger 140 to cool the refrigerant.

[0038] Figure 3 For Figure 1 is a perspective view of the air conditioning device 100 in the present application from a top-down perspective after removing the housing 111 and the supply air volute component 130. From Figure 3 , the exhaust air impeller 180 can be seen looking inward from the exhaust air outlet 117. The external air flow enters through the air inlet 115 and flows through the heat exchanger 140 under the drive of the exhaust air impeller 180 and is discharged from the exhaust air outlet 117. Combining the attached Figures 1 to 4 , the housing 111 of the present application is provided with an air inlet 115 and an exhaust air outlet 117, and an exhaust air passage 110a communicating the air inlet 115 and the exhaust air outlet 117 is formed inside the housing 110; the heat exchanger 140 is provided inside the housing 110 and is located on the flow path of the exhaust air passage 110a; further, a wind guiding member 150 is also provided inside the housing 110. The wind guiding member 150 is located between the heat exchanger 140 and the air inlet 115, and the wind guiding member 150 guides the air flow flowing in through the air inlet 115 to the heat exchanger 140.

[0039] In the technical solution of the present invention, by providing a wind guiding member 150 in the air conditioning device 100, during the heat exchange process of the heat exchanger 140, the wind guiding member 150 guides the air flow entering from the air inlet 115 to the heat exchanger 140. Thus, the wind guiding member 150 optimizes the air flow organization in the air conditioning device 100, changing the disordered flow state where the air flow entering the air conditioning device 100 in the past needs to flow through heat generating components such as the compressor 170 of the air conditioning device 100. This enables the air flow entering from the air inlet 115 not to be affected by other heat generating elements in the air conditioning device 100 and to flow through the heat exchanger 140 as much as possible for heat exchange before being discharged, thereby improving the heat exchange efficiency of the air conditioning device 100 and significantly enhancing the overall performance.

[0040] The main function of the wind guiding member 150 in this application is to guide the air flow entering from the air inlet 115 to the heat exchanger 140 for sufficient heat exchange and then discharge it. Moreover, a relatively important function of the wind guiding member 150 is to guide the air flow at the air inlet side near the heat exchanger 140, preventing the air flow from flowing through the gap between the heat exchanger 140 and the housing 111 and directly entering the exhaust air blower 180 without heat exchange with the heat exchanger 140 and being discharged. Therefore, the wind guiding member 150 can have various structural forms. For example, the wind guiding member 150 can be a horn-shaped or tubular structure enclosing a circle to make the air flow pass through the heat exchanger 140 as much as possible. For this purpose, the periphery of the end of the wind guiding member 150 facing the heat exchanger 140 is arranged around the edge of the heat exchanger 140. Here, the periphery of the end of the wind guiding member 150 facing the heat exchanger 140 being arranged around the edge of the heat exchanger 140 can be that the periphery of the wind guiding member 150 is located outside the outer edge of the heat exchanger 140 for surrounding, or the periphery of the wind guiding member 150 falls on the edge of the heat exchanger 140 for surrounding. The purpose is to confine the air flow in the heat exchange area of the heat exchanger 140, prevent the air flow from flowing through the gap between the heat exchanger 140 and the housing 111, and thereby improve the heat exchange efficiency.

[0041] Furthermore, since there are many heat generating components such as the compressor 170 (see Figure 5 ), capacitors, circuit boards, etc. inside the mobile air conditioning device, if the air flow entering from the air inlet 115 flows through the above devices, absorbs the heat of the above devices and then conducts heat exchange, it will affect the heat exchange efficiency. In this regard, in order to further improve the heat exchange efficiency, based on the above structural characteristics of the wind guiding member 150 of the air conditioning device 100 in this application, the wind guiding member 150 can also form a wind guiding cavity 110b with the housing 110 (see Figure 3), the air guiding cavity 110b is formed as the front section of the exhaust air passage 110a, and the air guiding cavity 110b communicates with the air inlet 115 and the air inlet side of the heat exchanger 140. The setting of the air guiding cavity 110b isolates the air flow entering the air inlet 115 from other heat generating components. On the one hand, it avoids the obstruction of the heat generating components to the air flow, which can improve the air flow velocity. On the other hand, it can make the entering air flow not easily carry the heat of the heat generating components, thereby comprehensively improving the heat exchange efficiency.

[0042] Specifically, in order to cooperate with the housing 110 to form the air guiding cavity 110b, the air guiding member 150 includes a first air guiding portion 151 covering the air inlet side of the heat exchanger 140. The heat exchanger 140 is placed on the chassis 113, the upper side of the heat exchanger 140 abuts against the middle partition plate assembly 120, and the lower side of the heat exchanger 140 abuts against the chassis 113. Among them, the upper side and the lower side of the first air guiding portion 151 are respectively connected to the middle partition plate assembly 120 and the chassis 113, and the two sides of the first air guiding portion 151 located between the middle partition plate assembly 120 and the chassis 113 respectively abut against the corresponding side plates of the heat exchanger 140. That is, the first air guiding portion 151 is integrally in the shape of a cover structure, which bulges outwards away from the heat exchanger 140 and has an air flow buffering cavity. Sealing side plates 1512 with a certain width are provided on both sides of the first air guiding portion 151 located between the middle partition plate assembly 120 and the chassis 113. After being assembled, after the upper side and the lower side of the first air guiding portion 151 are respectively connected to the middle partition plate assembly 120 and the chassis 113, the sealing side plates 1512 on the first air guiding portion 151 will fit onto the two side plates of the heat exchanger 140, so that the heat exchange air flow will be difficult to flow through the gap between the heat exchanger 140 and the outer shell 111 and enter the exhaust air impeller 180 to be discharged, thus improving the heat exchange effect. Among them, after the first air guiding portion 151 of the air guiding member 150 bulges outwards, it needs to avoid or cooperate with other structures of the air conditioning device 100. Therefore, the first air guiding portion 151 will be integrally constructed into an irregular housing 110 structure. Therefore, the air guiding member 150 as a whole can be made by die casting or injection molding, and the material can be plastic or alloy material (such as aluminum alloy), or the air guiding member 150 can be made by stamping and welding processes using sheet metal parts.

[0043] In order to prevent air leakage, the present application can also be provided with leak-proof members (not shown) between the periphery of the first air guiding portion 151 and the middle partition plate assembly 120, the heat exchanger 140 and the chassis 113. The material of the leak-proof member can be plastic, silica gel or sponge. After the air guiding member 150 is assembled, the leak-proof member can be clamped between the periphery of the first air guiding portion 151 and the middle partition plate assembly 120, the heat exchanger 140 and the chassis 113.

[0044] In order to achieve the stable assembly of the air guiding member 150 and a good air leakage prevention effect in the present application, please refer toFigures 4 to 7 On the chassis 113, a mounting platform 1131 is convexly provided. The heat exchanger 140 is disposed above the mounting platform 1131. The middle partition plate assembly 120 is convexly provided with a connecting portion 121 downward (see Figure 7 ). The upper side of the first air guiding portion 151 is connected to the connecting portion 121, and the lower side of the first air guiding portion 151 is connected to the mounting platform 1131. The heat exchanger 140 of the present application is integrally clamped between the mounting platform 1131 and the connecting portion 121. By connecting the upper side of the first air guiding portion 151 to the connecting portion 121 and the lower side of the first air guiding portion 151 to the mounting platform 1131, the alignment is more convenient and the connection is more stable.

[0045] To install the air guiding member 150, specifically, the connecting portion 121 and the mounting platform 1131 of the present application are both provided with mounting holes 1132, and the upper side and the lower side of the first air guiding portion 151 are both provided with connecting holes 1511. The first air guiding portion 151 is fixedly connected to the mounting platform 1131 and the connecting portion 121 respectively through the cooperation of the connecting member with the mounting holes 1132 and the connecting holes 1511. The connecting member can be a screw or a bolt structure. By using a screw or a bolt to detachably lock the air guiding member 150 to the middle partition plate and the chassis 113, the structure can be stable and the installation is also relatively convenient.

[0046] As can be seen from the above content, a compressor 170 is further provided on the chassis 113 in the lower layer space of the present application, and the first air guiding portion 151 in the air guiding member 150 is also located in the lower layer space. After the air guiding member 150 is installed, the first air guiding portion 151 will be located between the compressor 170 and the heat exchanger 140. That is, the first air guiding portion 151 isolates the compressor 170 and the heat exchanger 140, and the first air guiding member 150 further protrudes and bulges toward the side away from the heat exchanger 140 to form a special-shaped concave structure to adapt to the contour of the compressor 170. In this way, during the operation of the air conditioning device 100, the first air guiding portion 151 can also buffer the compressor 170 when the compressor 170 shakes during operation, so as to prevent it from colliding with the heat exchanger 140, and reduce the use of the support and protection device in the traditional mobile air conditioner.

[0047] Please refer to FIGS. 6 to Figure 8, during the operation of the air conditioning device 100 of the present application, the external air flow flows into the air guiding cavity 110b from the air inlet 115, enters the heat exchanger 140 from the air inlet side of the heat exchanger 140 for heat exchange, and then is discharged through the air outlet 117 via the air exhaust cavity 110c formed by the cooperation of the air exhaust volute cover 160 and the middle partition component 120. In order to improve the convenience of installing the air duct of the air conditioner and achieve the compactness of the overall structure, the present application is provided with the air inlet 115 and the air outlet 117 at the top of the outer shell 111. The air inlet 115 and the air outlet 117 provided at the top can make it easier to disassemble and assemble the branch pipe. Further, in order to realize the flow path of the external air flow from top to bottom to the heat exchanger 140, the air guiding member 150 further includes a second air guiding portion 153. The second air guiding portion 153 extends upward from the upper side of the first air guiding portion 151 to the air inlet 115. Correspondingly, the above-mentioned air exhaust volute cover 160 also extends upward from bottom to top to the air outlet 117, and the air exhaust cavity 110c is extended upward to the air outlet 117.

[0048] For the convenience of installing the second air guiding portion 153 and maintaining the airtightness of the air path, please refer to Figures 6 to 8 , the second air guiding portion 153 of the present application includes a sealing frame 1531 and an air guiding cylinder 1533. A abutting portion 122 extends upward from the middle of the middle partition component 120. The sealing frame 1531 is connected to the abutting portion 122 of the middle partition component 120 and clamps and fixes the air guiding cylinder 1533. The two ends of the air guiding cylinder 1533 are respectively communicated with the air inlet 115 and the inner cavity of the first air guiding portion 151. The air guiding cylinder 1533 and the sealing frame 1531 of the present application can be in a detachable manner or an integral manner. A bent stepped shape is formed at the connection between the sealing frame 1531 and the first air guiding portion 151. The abutting portion 122 also has a frame structure and forms an installation groove structure. During the assembly process, the sealing frame 1531 is buckled with the abutting portion 122, and the air guiding cylinder 1533 can be partially directly embedded into the installation groove in the abutting portion 122. The lower end of the air guiding cylinder 1533 is communicated with the inner cavity of the first air guiding portion 151 through the connection between the sealing frame 1531 and the first air guiding portion 151. The setting of the air guiding cylinder 1533 can ensure airtightness and enhance the structural strength of the entire air guiding member 150.

[0049] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
