[0002] An air conditioner is a device that can adjust and control parameters such as the temperature, humidity, and flow rate of the ambient air.

[0003] Air conditioners generally include a cold source, a heat source, and a fan. By controlling the operation of the cold source and the heat source, the temperature at the fan input can be made to reach the required temperature, and the airflow reaching the required temperature is transported to the external environment through the fan to achieve the effect of controlling the temperature of the external environment. Usually, the cold source is a heat exchanger.

[0004] In order to ensure the temperature stability and temperature accuracy of the air-conditioned object and facilitate temperature control, an electric heating device is installed at the heat exchanger to supplement the heating capacity of the heat exchanger. The electric heating device is fixed to the sheet metal of the end plates on both sides of the heat exchanger by screws. Since the air conditioner is usually installed against the wall, the back plate of the air conditioner is not easy to disassemble. When the electric heating device needs to be disassembled for maintenance, it is difficult to remove the screws close to the back plate side. The operating space is limited, and frequent disassembly and assembly of screws will not only cause the screw joints to slip easily and the fixing effect of the electric heating device to be poor, but the heat exchanger may also be scratched due to improper operation during the disassembly and assembly process, and even cause refrigerant leakage.

[0032] See Figure 1 and Figure 2 The utility model provides an air conditioner that is easy to maintain, including a support assembly 1, a heat exchanger 2, a fixing frame 3, an electric heating element 4 and a fan 5. The support assembly 1 includes a support frame 11; the heat exchanger 2 is arranged on the support frame 11; the fixing frame 3 is arranged at the cooling end of the heat exchanger 2, and the fixing frame 3 is slidably connected to the heat exchanger 2; the electric heating element 4 is arranged on the fixing frame 3 and is detachably connected to the fixing frame 3; the fan 5 is arranged at one end of the heat exchanger 2 and is connected to the support frame 11, for conveying airflow to the outside.

[0033] In this embodiment, the support frame 11 is a vertical frame structure, the heat exchanger 2 is arranged inside the support frame 11 and is detachably connected to the support frame 11; the length direction of the fixed frame 3 is parallel to the length direction of the heat exchanger 2, and the sliding direction of the fixed frame 3 is perpendicular to the length direction of the fixed frame 3. The electric heating element 4 is an electric heating tube, and multiple electric heating elements 4 are arranged at intervals along the length direction of the fixed frame 3, and the fan 5 is arranged at the top of the support frame 11.

[0034] In this way, the support frame 11 can provide stable support for the heat exchanger 2 and the fan 5. When the electric heating element 4 needs to be replaced and repaired, the fixing frame 3 is moved in a direction away from the heat exchanger 2, so that the electric heating element 4 set on the fixing frame 3 can be located in the external environment, avoiding the need for staff to complete the disassembly of the electric heating element 4 inside the support frame 11, thereby improving the convenience and safety of disassembly and assembly of the electric heating element 4.

[0035] It is understandable that the electric heating element 4 can also be other electric heating devices that can increase the temperature of the air around the heat exchanger 2, and no further examples are given here.

[0036] See Figure 1-Figure 3 In some embodiments, the air conditioner further includes a mounting bracket 6, which is disposed at the cooling end of the heat exchanger 2, and the fixing bracket 3 is slidably connected to the mounting bracket 6. Furthermore, two mounting brackets 6 are provided, one at the end of the heat exchanger 2 facing the fan 5 and the other at the end of the heat exchanger 2 facing away from the fan 5.

[0037] Among them, the length direction of the mounting frame 6 is parallel to the sliding direction of the fixing frame 3, the mounting frame 6 is provided with a slide groove 64, and the two ends of the fixing frame 3 are fixedly connected with sliders 31 that are adapted to the shape of the slide groove 64. The length direction of the slider 31 is parallel to the length direction of the mounting frame 6, and the length of the mounting frame 6 is not less than the width of the slider 31, so that when the fixing frame 3 is located in the support frame 11, the mounting frame 6 can stably support the slider 31 and the fixing frame 3.

[0038] Furthermore, a handle (not shown in the figure) is connected to the side of the fixing frame 3 facing the outside, so as to facilitate quick pulling of the fixing frame 3 when the electric heating element 4 is replaced or repaired.

[0039] In this way, sliders 31 are provided at both ends of the fixing frame 3, so that the sliders 31 can slide in the slide groove 64, which facilitates the stable movement of the fixing frame 3 along the sliding direction, and the two mounting frames 6 can form a stable support for the fixing frame 3, preventing the fixing frame 3 from deflecting or falling off on the mounting frames 6, thereby improving the safety of disassembly and assembly of the electric heating element 4.

[0040] See Figure 2 and Figure 4 In some embodiments, a fixing plate 32 is fixedly connected to the side of the fixing frame 3 facing away from the handle, the length direction of the fixing plate 32 is parallel to the length direction of the fixing frame 3, and the fixing plate 32 is detachably connected to the support frame 11 by bolts.

[0041] In this way, when the fixing frame 3 is located inside the support frame 11, the fixing plate 32 is connected to the support frame 11 by bolts, which can limit the position of the fixing frame 3 and prevent the slider 31 from moving in the slide groove 64. When the electric heating element 4 needs to be disassembled and replaced, the bolts on the fixing plate 32 are unscrewed to enable the slider 31 to move in the slide groove 64, and the fixing frame 3 drives the electric heating element 4 to move to the outside.

[0042] See Figure 5 and Figure 6 In some embodiments, the mounting bracket 6 includes a connecting portion 61 and a guiding portion 62 . The connecting portion 61 is detachably connected to the heat exchanger 2 . The guiding portion 62 cooperates with the connected portion 61 to form a slide groove 64 , so that the fixing bracket 3 moves in the slide groove 64 .

[0043] In this embodiment, the connecting portion 61 is detachably connected to the heat exchanger 2 by bolts, and the guiding portion 62 is a Z-shaped plate formed by bending sheet metal. The connecting portion 61 and the guiding portion 62 are detachably connected by bolts.

[0044] In this way, the slider 31 is set in the slide groove 64, and the guide part 62 can guide the slider 31 to slide along the length direction of the slide groove 64 to prevent the slider 31 from falling off the slide groove 64; the connecting part 61 is detachably connected to the heat exchanger 2, which is convenient for disassembly and assembly of the mounting bracket 6, and when the specifications of the fixing bracket 3 change, the distance between the two mounting brackets 6 can be adjusted to improve the flexibility of the mounting bracket 6, thereby facilitating the disassembly and assembly of the fixing bracket 3 and the electric heating element 4.

[0045] It can be understood that the connection method between the mounting bracket 6 and the heat exchanger 2 can be adjusted according to actual needs and is not limited to a detachable connection, but can also be a fixed connection. In this embodiment, the mounting bracket 6 and the heat exchanger 2 are detachably connected in order to improve the flexibility of the mounting bracket 6 and facilitate disassembly and assembly.

[0046] See Figure 3 In some embodiments, the mounting frame 6 is connected to a limiting member (not shown in the figure), and the limiting member can selectively abut against the fixing frame 3 to limit the sliding distance of the fixing frame 3.

[0047] In this embodiment, the limiting member is a limiting block. A limiting block is provided in each slide groove 64. The limiting block is provided at one end of the slide groove 64. When the slider 31 drives the fixing frame 3 to move in the direction close to the heat exchanger 2, the slider 31 abuts against the limiting block, which can limit the slider 31 from continuing to move. At this time, the fixing frame 3 and the electric heating element 4 are both located in the support frame 11.

[0048] In this way, the limit block can prevent the fixing frame 3 from excessive movement and collision with the support frame 11 or the heat exchanger 2, making it difficult for the slider 31 to fall out of the slide groove 64, and making it easier for staff to judge whether the fixing frame 3 is installed in place, thereby improving the convenience and safety of disassembly and assembly.

[0049] It is understandable that the limiting member can also be a spring, a buckle or other structure that can limit the movement of the slider 31 in the slide groove 64, which will not be elaborated here.

[0050] See Figure 6 In some embodiments, two heat exchangers 2 are provided, and the two heat exchangers 2 are arranged at an angle. The electric heating elements 4 are provided in a one-to-one correspondence with the heat exchangers 2, and the two electric heating elements 4 are provided on the side of the two heat exchangers 2 that is close to each other (i.e., the cooling end of the two heat exchangers 2). Furthermore, the end of the two heat exchangers 2 with a smaller distance between them is arranged away from the fan 5, and the end of the two heat exchangers 2 with a larger distance between them is arranged toward the fan 5.

[0051] In this embodiment, the two heat exchangers 2 are arranged in a V shape, and the fan 5 is arranged between the two heat exchangers 2 .

[0052] In this way, the two electric heating elements 4 are arranged on the side where the two heat exchangers 2 are close to each other, which not only makes full use of the space between the two heat exchangers 2 to make the structure more compact, but also facilitates the temperature adjustment of the air around the heat exchanger 2; since the two heat exchangers 2 are arranged at an angle, the two electric heating elements 4 are also arranged at an angle. When the electric heating elements 4 are repaired and replaced, interference is not easy to occur between the two electric heating elements 4. Only the electric heating element 4 on one side can be moved to the outside according to actual needs, thereby improving the flexibility and convenience of disassembly and assembly of the electric heating element 4.

[0053] It is understandable that the angles of the two heat exchangers 2 can be flexibly adjusted according to actual needs. The electric heating element 4 can be installed on both heat exchangers 2, or only on one heat exchanger 2. No further examples are given here.

[0054] See Figure 1 and Figure 2 In some embodiments, the mounting frame 6 is connected to a baffle 63 , and the baffle 63 cooperates with the heat exchanger 2 to form a temperature adjustment chamber 7 .

[0055] In this embodiment, two baffles 63 are provided, and the two baffles 63 are respectively located on both sides of the heat exchanger 2 and are detachably connected to the heat exchanger 2. The two sides of the baffle 63 are respectively connected to the side walls on the same side of the two heat exchangers 2, so that the two baffles 63 and the two heat exchangers 2 cooperate to form a temperature control chamber 7. The air inlet of the fan 5 is connected to the temperature control chamber 7, so that the airflow in the temperature control chamber 7 can be transported to the outside through the fan 5.

[0056] In this way, after the heat exchanger 2 and the electric heating element 4 jointly adjust the temperature of the air in the temperature control chamber 7, the baffle 63 can prevent the temperature-controlled air from leaking to the outside through both sides of the heat exchanger 2, thereby avoiding that the temperature difference between the air flow output by the fan 5 and the required temperature is too high, thereby improving the temperature control effect; when it is necessary to disassemble and replace the electric heating element 4, the baffle 63 can be removed to move the fixing frame 3, thereby improving the convenience of disassembly and assembly.

[0057] See Figure 4 In some embodiments, the electric heating element 4 is connected to a mounting end 41 , and the mounting end 41 is detachably connected to the fixing frame 3 .

[0058] Each electric heating element 4 is connected to two mounting ends 41 , which are respectively arranged at two ends of the electric heating element 4 , and the mounting ends 41 are detachably connected to the fixing frame 3 via bolts.

[0059] In this way, the electric heating element 4 is detachably connected to the fixing frame 3 through the mounting end 41, which makes it convenient to adjust the number and installation position of the electric heating elements 4 according to actual needs. When one or several of the electric heating elements 4 need to be replaced or repaired, the fixing frame 3 is moved to the outside, and after replacing the electric heating element 4 to be repaired or replaced, the fixing frame 3 is moved into the support frame 11, so that the electric heating element 4 can be quickly repaired and replaced, thereby improving the disassembly and assembly efficiency.

[0060] See Figure 1 In some embodiments, the support assembly 1 further includes a first support plate 12 and a second support plate 13 , both of which are connected to the support frame 11 , the fan 5 is arranged on the first support plate 12 , and the heat exchanger 2 is arranged on the second support plate 13 .

[0061] Among them, the first support plate 12 and the second support plate 13 are both horizontally arranged plate-like structures, the fan 5 is detachably connected to the first support plate 12, and an air inlet hole (not shown in the figure) is opened at the position corresponding to the air inlet of the fan 5 on the first support plate 12, and the ends of the two heat exchangers 2 facing away from the fan 5 are detachably connected to the second support plate 13.

[0062] In this way, the first support plate 12 and the second support plate 13 can provide stable support for the fan 5, the heat exchanger 2 and the electric heating element 4, improve the safety of the disassembly and assembly of the electric heating element 4, and avoid bumps, deviations, falling off, etc. when the fixing frame 3 drives the electric heating element 4 to move.

[0063] It is understandable that the connection method between the fan 5 and the first support plate 12, and the connection method between the heat exchanger 2 and the second support plate 13 are not limited to detachable connections, but can also be fixed connections. The specific connection method can be adjusted according to actual needs and will not be listed in detail here.

[0064] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
