Summary of the Utility Model

[0003] In view of the above problems, the present utility model is proposed to provide an air conditioner that can overcome or at least partially solve the above problems, and can solve the problem that part of the windward surface of the inner heat exchanger is blocked by the electric control box, resulting in the blockage of the air inlet of the heat exchange air duct, thereby affecting the heat exchange effect of the air conditioner.

[0041] Figure 1 is a schematic structural diagram of an air conditioner according to an embodiment of the present utility model, as Figure 1 shown, and with reference to Figures 2 to 5 , the embodiment of the present utility model provides an air conditioner. The air conditioner includes a housing 100, a heat exchanger 200, and an electric control box 300. An air inlet 110 is provided on the front side wall of the housing 100. The heat exchanger 200 is disposed inside the housing 100.

[0042] The electric control box 300 is disposed inside the housing 100 and is located above the air inlet 110. The lower side wall of the electric control box 300 is spaced apart from the heat exchanger 200 to form an air inlet duct 130 between the lower side wall of the electric control box 300 and the heat exchanger 200.

[0043] In this embodiment, air enters the interior of the housing 100 through the air inlet 110 provided on the front side wall of the housing 100. The lower side wall of the electric control box 300 is spaced from the heat exchanger 200, so that part of the air flows through the air inlet duct 130, avoiding the influence of the electric control box 300 on the air inlet duct 130 for air to enter the interior of the housing 100.

[0044] Moreover, the lower side wall of the electric control box 300 forms the side wall of the air inlet duct 130, so that there is no need to separately provide the side wall of the air inlet duct 130 during the production and manufacturing process of the air conditioner, reducing the number of components inside the housing 100, saving the usage cost of materials, and also reducing the difficulty of production and manufacturing of the air conditioner and the production and manufacturing cost of the air conditioner. Due to the reduction of components inside the housing 100, the arrangement of components inside the housing 100 is more compact, and thus the overall volume of the housing 100 is reduced.

[0045] In some embodiments of the present utility model, the housing 100 extends horizontally, as Figure 1 and Figure 2 shown, the air inlet 110 extends along the length direction of the housing 100.

[0046] In some embodiments of the present utility model, as Figure 4 shown, the electric control box 300 extends along the length direction of the housing 100, and the electric control box 300 is located above the front of the heat exchanger 200.

[0047] In some other embodiments of the present utility model, the electric control box 300 is located above the rear of the heat exchanger 200.

[0048] In some embodiments of the present utility model, as Figure 3 shown, the lower side wall of the electric control box 300 includes a first air guiding surface 310 and a second air guiding surface 320.

[0049] A first air duct section that tapers from front to back is formed between the first air guiding surface 310 and the heat exchanger 200.

[0050] The second air guiding surface 320 is fixedly connected to the rear end of the first air guiding surface 310. The front end of the first air guiding surface 310 is connected to the upper end of the air inlet 110. A second air duct section with a constant diameter from front to back is formed between the second air guiding surface 320 and the heat exchanger 200.

[0051] In this embodiment, both the first air duct section and the second air duct section are located inside the air inlet duct 130. The first air guiding surface 310 plays a guiding role in guiding the air after it enters the air inlet duct 130 to ensure the smooth flow of the air into the interior of the air inlet duct 130. The end of the first air duct section close to the air inlet 110 is larger, reducing the interference with the air entering the air inlet 110 and increasing the flow rate of the air entering from the air inlet 110.

[0052] The second air duct section has a constant diameter from front to back, which not only avoids interference between the positions of the electric control box 300 and the heat exchanger 200, but also reduces the distance between the electric control box 300 and the heat exchanger 200 while ensuring the air flow rate. Furthermore, it reduces the occupied volume of the electric control box 300 within the housing 100, achieving the purpose of reducing the overall volume of the air conditioner and increasing the available usage scenarios of the air conditioner.

[0053] In some other embodiments of the present invention, a second air duct section that tapers from front to back is formed between the second air guiding surface 320 and the heat exchanger 200.

[0054] In some other embodiments of the present invention, a second air duct section that expands from front to back is formed between the second air guiding surface 320 and the heat exchanger 200.

[0055] In some embodiments of the present invention, as Figure 3 and Figure 4 shown, the first air guiding surface 310 extends backward along the horizontal direction from the upper edge of the air inlet 110.

[0056] In this embodiment, the first air guiding surface 310 is fixedly connected to the front end of the second air guiding surface 320. The first air guiding surface 310 guides the air to come into full contact with the heat exchanger 200 when entering from the air inlet 110.

[0057] In order to ensure that the computer board 340 of the air conditioner can be installed on the first air guiding surface 310 within the electric control box 300, the distance between the first air guiding surface 310 and the top plate of the housing 100 at least meets the size required for installing the computer board 340. Moreover, since the first air guiding surface 310 is fixedly connected to the front edge of the air inlet 110, setting the first air guiding surface 310 along the air inlet direction, i.e., the horizontal direction, can make the area of the air inlet 110 larger compared with setting it to incline forward and downward. This improves the air inlet efficiency of the air conditioner.

[0058] In some embodiments of the present invention, as Figure 3 shown, the heat exchanger 200 includes a first heat exchange section 210, and the first heat exchange section 210 is in a plate shape. The first heat exchange section 210 is inclined backward and upward, so that there is an included angle between the first heat exchange section 210 and the air inlet 110.

[0059] In this embodiment, there is an included angle between the first heat exchange section 210 and the air inlet 110, and the first heat exchange section 210 is inclined, so that the contact area between the air entering the housing 100 and the first heat exchange section 210 is larger, improving the heat exchange efficiency of the air conditioner.

[0060] In some embodiments of the present invention, as Figure 3 shown, the included angle α between the first heat exchange section 210 and the air inlet 110 is 15° to 75°.

[0061] In some embodiments of the present utility model, as Figure 3 shown, the included angle β between the second air guiding surface 320 and the first heat exchange section 210 is 0° to 15°.

[0062] In this embodiment, when the opening of the included angle β between the second air guiding surface 320 and the first heat exchange section 210 faces forward, the second air duct section is of a tapered type.

[0063] When the opening of the included angle β between the second air guiding surface 320 and the first heat exchange section 210 faces backward, the second air duct section is of a divergent type.

[0064] When the included angle β between the second air guiding surface 320 and the first heat exchange section 210 is 0°, that is, when the second air guiding surface 320 is parallel to the first heat exchange section 210, the second air duct section is of an equal-diameter type.

[0065] In some embodiments of the present utility model, as Figure 3 shown, the heat exchanger 200 further includes a second heat exchange section 220, and the second heat exchange section 220 is fixedly connected to the rear end of the first heat exchange section 210.

[0066] The lower side wall of the electric control box 300 further includes a third air guiding surface 330, and the third air guiding surface 330 is fixedly connected to the rear end of the second air guiding surface 320.

[0067] The third air guiding surface 330 is spaced above the connection between the first heat exchange section 210 and the second heat exchange section 220.

[0068] In this embodiment, a second heat exchange section 220 is added at the rear side of the first heat exchange section 210 to improve the heat exchange efficiency of the air conditioner. The third air guiding surface 330 is spaced from the second heat exchange section 220 so that air can also fully contact the upper side of the heat exchanger 200 to further improve the heat exchange efficiency of the air conditioner.

[0069] In some embodiments of the present utility model, as Figure 3 shown, the front end of the second heat exchange section 220 is fixedly connected to the rear end of the first heat exchange section 210.

[0070] The second heat exchange section 220 is inclined backward and downward, and there is an included angle with the first heat exchange section 210.

[0071] In this embodiment, the front end of the second heat exchange section 220 is connected to the rear end of the first heat exchange section 210, and there is an included angle between the first heat exchange section 210 and the second heat exchange section 220, so that the blower of the air conditioner can be installed below the first heat exchange section 210 and the second heat exchange section 220. The setting of the included angle between the first heat exchange section 210 and the second heat exchange section 220 provides space for the installation of the blower, making the structure inside the housing 100 more compact, improving the space utilization rate inside the housing 100, and reducing the overall volume of the housing 100.

[0072] In some embodiments of the present utility model, as Figure 3 shown, the rear end of the first heat exchange section 210 is located above the air inlet 110.

[0073] In this embodiment, a part of the first heat exchange section 210 is located above the air inlet 110 to increase the heat exchange surface of the heat exchanger 200. The lower side wall of the electric control box 300 guides the air flow to contact the part of the first heat exchange section 210 located above the air inlet 110, so that the heat exchange efficiency of the air conditioner is improved, and thus the user experience is improved.

[0074] In some embodiments of the present utility model, as Figure 3 shown, the rear end of the first heat exchange section 210 and the front end of the second heat exchange section 220 are both located above the air inlet 110.

[0075] The rear end of the second heat exchange section 220 is in contact connection with the rear side wall of the housing 100.

[0076] In this embodiment, part of the first heat exchange section 210 and the second heat exchange section 220 are located above the air inlet 110 to increase the heat exchange surface of the heat exchanger 200. The lower side wall of the electric control box 300 guides the air flow to contact the part of the first heat exchange section 210 and the second heat exchange section 220 located above the air inlet 110, so that the heat exchange efficiency of the air conditioner is improved, and thus the user experience is improved. Moreover, the lower side wall of the electric control box 300 is spaced from the heat exchanger 200, which not only avoids interference between the installation positions of the electric control box 300 and the heat exchanger 200, but also reduces the interval distance between the electric control box 300 and the heat exchanger 200 while ensuring the air flow rate, thereby reducing the occupied volume of the electric control box 300 inside the housing 100, achieving the purpose of reducing the overall volume of the air conditioner and increasing the available usage scenarios of the air conditioner.

[0077] After the air enters the air inlet duct 130, part of the air passes through the top of the heat exchanger 200 and is guided to the rear side of the housing 100. The air flow at the rear side of the housing 100 is blocked by the rear side wall of the housing 100, flows downward along the rear side wall of the housing 100, and exchanges heat with the second heat exchange section 220, so that the air entering the housing 100 from the air outlet 120 can fully contact the heat exchanger 200, further improving the heat exchange efficiency of the air conditioner.

[0078] In some embodiments of the present invention, as Figure 3 shown, the heat exchanger 200 further includes a third heat exchange section 230. The third heat exchange section 230 is in a plate shape and is arranged parallel to the air inlet 110. The upper end of the third heat exchange section 230 is fixedly connected to the lower end of the first heat exchange section 210.

[0079] In this embodiment, the third heat exchange section 230 is arranged close to the air inlet 110 and is parallel to the air inlet 110, so that part of the air directly exchanges heat through the third heat exchange section 230 when entering from the air inlet 110, and the other part of the air flows backward and upward through the gap between the electric control box 300 and the third heat exchange section 230, so that the air can flow through the first heat exchange section 210, the second heat exchange section 220 and the third heat exchange section 230, thereby increasing the heat exchange area and improving the heat exchange effect of the air conditioner.

[0080] In some alternative embodiments of the present invention, as Figure 5 shown, the heat exchanger 200 includes a first heat exchange section 210. The first heat exchange section 210 is in an arc shape protruding forward, and the rear end of the first heat exchange section 210 is located above the air inlet 110.

[0081] The second air guiding surface 320 is in an arc shape and is coaxial with the first heat exchange section 210.

[0082] In this embodiment, the second air guiding surface 320 is coaxially arranged with the first heat exchange section 210, so that the air inlet duct 130 between the second air guiding surface 320 and the first heat exchange section 210 is of equal height to ensure the passage of air in the air inlet duct 130. The coaxially arranged second air guiding surface 320 and the first heat exchange section 210 not only avoid the interference caused by the setting of the electric control box 300 and the heat exchanger 200, but also because the second air guiding surface 320 and the first heat exchange section 210 can be arranged as close to each other as possible, reducing the occupied volume of the electric control box 300 in the housing 100, and further reducing the overall volume of the air conditioner, increasing the available scenarios of the air conditioner.

[0083] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, an air outlet 120 is provided on the front side wall of the housing 100. The air inlet 110 and the air outlet 120 are spaced apart and staggered.

[0084] In this embodiment, air enters the air inlet duct 130 from the air inlet 110, and flows out from the air outlet 120 after passing through the heat exchanger 200. Since the air inlet 110 and the air outlet 120 are staggered, the air entering the air inlet duct 130 will be affected by the air outlet 120 staggered with the air inlet 110 and flow towards the air outlet 120, resulting in a smaller air volume on the side of the air inlet 110 away from the air outlet 120. The electric control box 300 is arranged outside the air inlet duct 130, that is, on the side of the air inlet 110 away from the air outlet 120, so as to avoid the electric control box 300 interfering with the air inlet and outlet of the air conditioner as much as possible, and further avoid the setting of the electric control box 300 having a greater impact on the air inlet and outlet air volumes of the air conditioner, thereby improving the heat exchange efficiency of the air conditioner.

[0085] In some embodiments of the present utility model, an air outlet 120 is provided on the front side wall of the housing 100. The air outlet 120 is located above the air inlet 110.

[0086] In some other embodiments of the present utility model, as Figure 2 shown, an air outlet 120 is provided on the front side wall of the housing 100. The air outlet 120 is located below the air inlet 110.

[0087] In this embodiment, the air conditioner is usually installed near the ceiling, that is, the lower side of the air conditioner is closer to the user. The air outlet 120 is arranged below the air inlet 110, and the heat exchange air is guided by the air deflector of the air outlet 120 and blown towards the lower side of the air inlet 110, avoiding the heat exchange air being blown out from the air outlet 120 and then entering from the air inlet 110, thereby improving the heat exchange efficiency.

[0088] In some embodiments of the present utility model, the air conditioner is a wall-mounted air conditioner.

[0089] In some embodiments of the present utility model, the air conditioner is a cabinet-embedded air conditioner.

[0090] In this embodiment, the cabinet-embedded air conditioner is usually installed inside the cabinet. The electric control box 300 is installed above the heat exchanger 200, which can avoid the electric control box 300 occupying the space on both lateral sides of the housing 100, making the width of the air conditioner narrower and facilitating the installation inside the cabinet. Both the air inlet 110 and the air outlet 120 are provided on the front side wall of the housing 100, without being restricted by the cabinet, and it is more convenient for the installation and use of the cabinet-embedded air conditioner.

[0091] In some embodiments of the present utility model, when the user needs the air conditioner to refrigerate, the heat exchanger 200 is an evaporator.

[0092] In this embodiment, normal temperature air enters the air inlet duct 130 from the air inlet 110, and after passing through the evaporator, the temperature becomes lower and then flows out from the air outlet 120 to provide cold air for users. Since the density of cold air is higher than that of normal temperature air and hot air, the air outlet 120 is arranged below the air inlet 110, which avoids the cold air flowing out from the air outlet 120 and then entering from the air inlet 110, thereby improving the heat exchange efficiency.

[0093] At this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and determined to cover all these other variations or modifications.
