Description

Technical Field

[0001] This invention relates to the field of household appliances, and more specifically, to a ceiling-mounted air conditioner. Background Technology

[0002] Currently, in air conditioners, the evaporator plays a crucial role in the performance of the air conditioning system, directly affecting the user experience. Related technologies, such as... Figure 1 As shown, the system includes an evaporator and a surrounding panel. The evaporator has a straight section structure, and a water pump is installed between the straight section structure and the surrounding panel. However, due to the straight section structure of the evaporator, the space outside the straight section is narrow, which causes great inconvenience to the staff during the installation and maintenance of the water pump. In addition, installing the water pump on the side of the straight section will disrupt the uniformity of airflow in the air outlet duct, resulting in uneven heat distribution of the air blown out of the ceiling unit. This causes the air temperature to vary in different areas of the ceiling unit, reducing the user's comfort. Summary of the Invention

[0003] In view of this, the present invention aims to provide a ceiling-mounted air conditioner. This addresses the problem in existing technologies where the evaporator has a straight section structure, with a water pump installed between the straight section and the surrounding panel. However, the straight section structure results in limited space on the outer side of the straight section, causing significant inconvenience for workers during water pump installation and maintenance. Furthermore, installing the water pump on the straight section side disrupts the uniformity of airflow within the exhaust duct, leading to uneven heat distribution in the air blown from the ceiling-mounted air conditioner and varying air temperatures across different areas, thus reducing user comfort.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] A ceiling-mounted air conditioner includes an evaporator, which includes multiple straight heat exchange channels. Two adjacent straight heat exchange channels are connected by an arc-shaped channel. The two ends of the evaporator include a first end and a second end. The distance from the second end to the outer side of the first end is L5, and the distance from the first end to the outer side of the second end is L6, wherein L5 / L6≤1.

[0006] This design, through the connection of adjacent straight heat exchange channels with arc-shaped channels and the proportional relationship between the dimensions of the first and second ends, ensures that the length of the existing evaporator remains essentially unchanged. That is, while ensuring that the heat exchange capacity of the evaporator remains unchanged, the ends of the evaporator can accommodate water pumps and inlet / outlet pipes, greatly facilitating the installation and maintenance of water pumps for staff. In addition, installing water pumps at the ends of the evaporator will not disrupt the uniformity of airflow in the air outlet duct, resulting in more even heat distribution from the ceiling unit and ensuring that the air temperature blown from different areas of the ceiling unit is the same, thus improving user comfort.

[0007] Further, the distance L5 from the second end to the outer side edge of the first end is 170-190mm, and the distance L6 from the first end to the outer side edge of the second end is 200-230mm.

[0008] The arrangement facilitates the installation of the water pump between the first end and the second end, and facilitates the installation and maintenance of workers.

[0009] Further, the plurality of straight heat exchange channels include a first heat exchange channel, a second heat exchange channel, a third heat exchange channel, and a fourth heat exchange channel connected in sequence, the first heat exchange channel and the second heat exchange channel are connected through a first arc-shaped channel, the second heat exchange channel and the third heat exchange channel are connected through a second arc-shaped channel, and the third heat exchange channel and the fourth heat exchange channel are connected through a third arc-shaped channel.

[0010] The arrangement can increase the space between the first end and the second end.

[0011] Further, the inner radius of the first arc-shaped channel is R1, the inner radius of the second arc-shaped channel is R2, and the inner radius of the third arc-shaped channel is R3, wherein R1=R2≤R3.

[0012] The arrangement can increase the distance between the first end and the second end of the evaporator, so that the water pump can be arranged between the first end and the second end, avoiding the influence of the water pump on the uniformity of the air outlet temperature of the ceiling machine, and improving the comfort of user use

[0013] Further, the first end is arranged at one end of the first heat exchange channel away from the second heat exchange channel, and the second end is arranged at one end of the fourth heat exchange channel away from the third heat exchange channel.

[0014] Further, the length of the first heat exchange channel is L1, the length of the second heat exchange channel is L2, the length of the third heat exchange channel is L3, and the length of the fourth heat exchange channel is L4, wherein L1<L4<L3<L2.

[0015] The arrangement can improve the space between the ends of the evaporator, facilitate the installation of the water pump at the ends of the evaporator, and also facilitate the maintenance of the water pump, and the installation of the water pump to the ends of the evaporator will not affect the air outlet efficiency.

[0016] Further, the inner radius R1 of the first arc-shaped channel, the inner radius R2 of the second arc-shaped channel, and the inner radius R3 of the third arc-shaped channel are 90-100mm.

[0017] The arrangement facilitates the improvement of the space between the ends of the evaporator, facilitates the installation of the water pump at the ends of the evaporator, and also facilitates the maintenance of the water pump, and the installation of the water pump to the ends of the evaporator will not affect the air outlet efficiency.

[0018] Further, the first end portion and the second end portion are connected by an evaporator connecting plate.

[0019] This arrangement avoids the wind from the end of the evaporator, reducing the working efficiency of the ceiling machine.

[0020] Further, it also includes an electric heating device, a wire pressing device, and a bottom plate, wherein the bottom plate is provided with a bottom plate foam, the electric heating device and the wire pressing device are arranged on the bottom plate through the bottom plate foam, and the electric heating device and the wire pressing device are arranged on the inside of the evaporator in a circumferential staggered manner.

[0021] This arrangement can effectively avoid the overlap between the wire pressing device and the electric heating device, so as to avoid mutual interference and affect the disassembly efficiency of the ceiling machine. In addition, the auxiliary action of the bottom plate foam can also improve the safety of the operation of the internal devices of the ceiling machine, and is also beneficial to the isolation between the devices, effectively avoiding the mutual interference between the components in the ceiling machine, improving the independence of the devices, saving the space of the internal cavity of the ceiling machine, and enhancing the heat exchange efficiency.

[0022] Further, it also includes a water pump assembly arranged on the bottom plate and close to the first end portion. This arrangement can effectively avoid the influence of the water pump assembly on the uniformity of the air outlet duct outside the evaporator, and also facilitates the installation and maintenance of the water pump assembly.

In addition, the installation of the water pump at the end of the evaporator will not damage the uniformity of the airflow in the air outlet duct, and the heat quantity of the air blown from the ceiling machine is more uniform, so that the temperature of the air blown from different areas of the ceiling machine is the same, improving the comfort of the user.

[0044] Example 1

[0047] The present application can ensure that the length of the existing evaporator is basically unchanged, that is, the heat exchange capacity of the evaporator is unchanged, so that the end portion of the evaporator can accommodate the water pump and the pipeline of the inlet and outlet pipes, which brings great convenience to the workers during the installation and maintenance of the water pump. In addition, the installation of the water pump at the end portion of the evaporator will not destroy the uniformity of the airflow in the air outlet duct, the heat quantity of the air blown from the ceiling machine is more uniform, the temperature of the air blown from different areas of the ceiling machine is the same, and the comfort of the user is reduced.

[0048] Specifically, the water pump assembly is arranged on the bottom plate and close to the first end portion 1011.

[0053] Specifically, the inner radius of the first arc-shaped channel A is R1, the inner radius of the second arc-shaped channel B is R2, and the inner radius of the third arc-shaped channel C is R3, wherein R1 = R2 ≤ R3. Preferably, R1 = R2 = R3 = 90-100 mm, and more preferably, R1 = R2 = R3 = 94 mm. This arrangement can increase the space at the end of the evaporator, facilitating the placement of the water pump in the space, and facilitating the installation and maintenance of the water pump.

[0054] In addition, in the prior art, for air conditioners equipped with electric heating, in order to ensure the safe operation of the electric heating, a sensor for collecting the temperature of the electric heating is usually installed on the electric heating, and a controller is used to control the operation of the electric heating according to the collected temperature, so as to prevent accidents from occurring to the electric heating and causing fire hazards; however, the existing form of the sensor equipped on the electric heating is complex, the safety is low, and the electric heating is placed at the straight section of the evaporator, as shown in Figure 1 , occupying a large amount of space.

[0055] In order to solve the problems of the existing technology, such as the complicated layout inside the ceiling machine, especially the large space occupied by the setting position of the electric heating device and the line pressing device in the ceiling machine, and the low disassembly and assembly efficiency, another embodiment of the present application provides a ceiling machine further comprising an electric heating device 300 and a line pressing device 400, the electric heating device 300 and the line pressing device 400 are arranged in the gap between the fan and the evaporator, the bottom plate 600 is provided with a bottom plate foam 601, the bottom plate foam 601 is provided with a plurality of first avoiding notches 6011 and second avoiding notches 6012, and the electric heating device 300 and the line pressing device 400 are arranged on the bottom plate 600 through the first avoiding notches 6011 and the second avoiding notches 6012 of the corresponding bottom plate foam 601 and located inside the surrounding plate, preferably, the electric heating device 300 and the line pressing device 400 are arranged in the gap between the evaporator and the fan along the circumference. Through the layout inside the ceiling machine, the setting position of the electric heating device 300 and the line pressing device 400 can be optimized, the component layout inside the ceiling machine can be improved, the space occupancy rate of the electric heating device 300 and the line pressing device 400 inside the ceiling machine can be saved, the heat exchange efficiency inside the ceiling machine can be increased, the disassembly and assembly efficiency of the ceiling machine can be improved, the maintenance cost of the ceiling machine can be reduced, the setting of the bottom plate foam 600 can improve the stability and safety of the installation of the electric heating device 300 and the line pressing device, effectively protect other devices, improve the heat preservation and insulation effect, and thus improve the heat exchange efficiency of the evaporator.

[0056] Specifically, the electric heating device 300 and the line pressing device 400 are each arranged at least one, and the number of the first avoiding notches and the second avoiding notches corresponds to the number of the corresponding electric heating device and line pressing device. The electric heating device 300 is arranged at the position corresponding to the arc-shaped channel of the evaporator, the electric heating device 300 is arranged inside the arc-shaped channel, and the projection shape of the electric heating device 300 is square or arc-shaped; the projection shape of the electric heating device 400 is square, such as Figures 2-3As shown, the electric heating device 300 is arranged on the inner side of the arc-shaped channel, and the long side of the electric heating device 300 is arranged at an acute angle a with the flat heat exchange channel of the evaporator 100, and the value of a is in the range of (0°, 90°), and preferably a = 45°. The projection shape of the electric heating device 300 is arc-shaped, the electric heating device 300 is arranged in the shape of the arc-shaped channel, and there is a certain gap between the electric heating device 300 and the arc-shaped channel. The arrangement of the electric heating device 300 is beneficial to save the space inside the ceiling machine and increase the heat exchange efficiency of the evaporator 100. In addition, the electric heating device 300 comprises an electric heater 301 and a support column 302. The electric heater 301 is connected with the support column 302 through screws. The support column 302 is arranged on the bottom plate through the first avoiding gap 6011 of the bottom plate foam 601. The opening shape of the first avoiding gap is consistent with the bottom shape of the electric heating device 300, which is convenient for the end of the support column of the electric heating device to pass through the surrounding plate. The electric heater 301 comprises an electric heating sheet and a heating bracket. The heating bracket is arranged at least two. The electric heating sheet is arranged on the inner side of the two heating brackets. The two heating brackets are connected with the support column through screws respectively. The wire pressing device 400 is arranged on the inner side of the flat heat exchange channel. The arrangement position of the wire pressing device 400 corresponds to the arrangement position of any one of the second heat exchange channel 102, the third heat exchange channel 103 and the fourth heat exchange channel 104, or the arrangement position of the wire pressing device 6 corresponds to the arrangement position of any multiple of the second heat exchange channel 102, the third heat exchange channel 103 and the fourth heat exchange channel 104 respectively. The wire pressing device 400 is a wire pressing buckle, which is used for the function of summarizing and combing the connecting wires of the internal components of the ceiling machine. The wire pressing device 400 is arranged on the bottom plate through the second avoiding gap. The opening shape of the second avoiding gap is consistent with the bottom shape of the wire pressing device, which is convenient for the end of the wire pressing device to pass through the surrounding plate.

[0057] Preferably, three electric heating devices 300 and three wire pressing devices 400 are arranged. The electric heating devices 300 are arranged on the inner side of the positions of the three arc-shaped channels respectively.

The bottom plate foam further comprises a fourth avoiding gap. The opening shape of the fourth avoiding gap is consistent with the bottom shape of the fixing bracket, which is convenient for the end of the fixing bracket to be installed close to the surrounding plate.

[0058] The special arrangement of the electric heating device is different from the prior art, in which the electric heating device is arranged inside the straight section 9 of the evaporator. The electric heating device not only occupies a large space inside the ceiling machine, but also easily limits the arrangement position of the wire pressing buckle, thereby causing poor stability of the layout of the components inside the ceiling machine, and failing to effectively realize the stability and reliability of the ceiling machine operation. In the present application, the electric heating device is detachably arranged with the support column 302, which can improve the installation efficiency of the electric heating device 300 during installation, and can reduce the opening size of the first avoiding gap on the bottom plate foam 601, thereby enhancing the strength of the bottom plate foam 601, avoiding the problem of low structure strength of the bottom plate foam due to too many avoiding gaps, and effectively enhancing the protection of the components inside the evaporator of the bottom plate foam 600, improving the stability and safety of the components inside the ceiling machine.

[0059] Embodiment 2

[0060] Based on embodiment 1, as shown in Figures 4-12 The water pump assembly is arranged on the support 1. The water pump assembly, the bottom plate and the support are arranged on the ceiling machine to accommodate and protect the components of the ceiling machine, avoid collision between other objects and the components of the ceiling machine, and improve the reliability of the ceiling machine during transportation, installation and use. The ceiling machine generates condensate water in the refrigeration mode, and the water pump assembly is used to timely discharge the condensate water to ensure the safety of the ceiling machine and avoid affecting the normal operation of the ceiling machine. The support 1 is used to support and install the water pump assembly.

[0061] Specifically, the surrounding plate 700 has a first gap 701, and the bracket 1 is detachably arranged at the first gap 701 and blocks the first gap 701, preventing the first gap 701 from affecting the air inlet and outlet of the ceiling machine, and also facilitating the integrity and aesthetics of the water pump assembly, the chassis and the bracket. Since the water pump assembly is arranged on the bracket 1, and the bracket 1 is detachable, the water pump assembly can be exposed to the outside view by only detaching the bracket 1, and is not blocked by other components of the ceiling machine, so that the maintenance personnel can more intuitively observe the condition of the water pump assembly. At the same time, the surrounding plate 700 is arranged with the first gap 701, and the water pump assembly is installed at the first gap 701, so that there is no need to arrange an access hole on the water pump assembly, the chassis and the bracket. The maintenance personnel does not need to put hands or maintenance tools into the narrow access hole, so that the maintenance personnel obtains a larger operation space. The maintenance personnel only needs to detach the bracket 1 to realize the detachment of the water pump assembly, so that the maintenance personnel can disassemble and maintain the water pump assembly outside the ceiling machine, reducing the maintenance difficulty and cost. In the prior art, the surrounding plate 700 is a whole without the first gap 701, and the present application is equivalent to using part of the surrounding plate 700 at the first gap 701 as the bracket 1, so that the water pump assembly, the chassis and the bracket can be reasonably utilized, and no other structure needs to be introduced.

[0062] Specifically, the projection area of the bottom plate on the ceiling is a polygon, the first gap 701 is formed at the corner of the bottom plate, and the first gap 701 is located in the accommodating space formed by the first end 1011 and the second end 1041, and the first gap 701 is close to the first end 1011. By increasing the accommodating space of the first end and the second end, the water pump assembly is arranged in the space, and the first gap is arranged close to the first end. Not only can the water pump assembly be avoided from protruding too much on the ceiling machine, thereby reducing the occupied space of the ceiling machine, but also can improve the overall and aesthetic appearance of the ceiling machine. When the water pump is installed and maintained, it brings great convenience to the workers, and will not damage the uniformity of the airflow in the air outlet air duct. The heat of the air blown from the ceiling machine is more uniform, the temperature of the air blown from different areas of the ceiling machine is the same, and the comfort of the user is improved. The water pump assembly includes at least one of the water pump 2 and the float switch 3. In this application, the water pump assembly includes the water pump 2 and the float switch 3, which facilitates the maintenance of the water pump 2 and the float switch 3 by disassembling the bracket 1. The float switch 3 is used to monitor the water level, and when the water level exceeds a certain height, it is discharged in time by the water pump 2. The bracket 1 includes a first support table 11, a second support table 12 and a baffle 13, the baffle 13 blocks the first gap 701, and the first support table 11 and the second support table 12 are arranged on the inner side of the first gap 701. That is, the first support table 11 and the second support table 12 are located in the space surrounded by the baffle 13 and the bottom plate, preventing the first support table 11 and the second support table 12 from being directly exposed to the outside of the bottom plate, and avoiding the first support table 11 and the second support table 12 from being collided by external objects. The water pump 2 is arranged on the first support table 11, and the float switch 3 is arranged on the second support table 12. The water pump 2 is installed by using the first support table 11, and the float switch 3 is installed by using the second support table 12, which can make the layout of the water pump assembly more clear and reasonable, avoid interference between the water pump 2 and the float switch 3, and facilitate maintenance personnel to better distinguish and observe each component of the water pump assembly. The first support table 11 can bear the gravity of the water pump 2, and the second support table 12 can bear the gravity of the float switch 3, which optimizes the stress point distribution of the water pump 2 and the float switch 3 during assembly, and is beneficial to improve the stress distribution during related assembly. Since the first support table 11 and the second support table 12 are located in the space surrounded by the baffle 13 and the bottom plate, the water pump assembly can be protected by the bracket 1 and the bottom plate to prevent collision between other components and the water pump assembly.

[0063] Specifically, the baffle 13 is provided with a drain pipe water nozzle 15. The water pump 2 includes a water inlet, a drain outlet and a drain pipe 4, one end of the drain pipe 4 is communicated with the drain outlet, and the other end is communicated with the drain pipe water nozzle 15. When the water pump 2 works, the condensed water extracted by the water pump 2 enters from the water inlet, and is drained to the outside of the bottom plate through the drain pipe 4 and the drain pipe water nozzle 15 and discharged.

[0064] Specifically, the baffle 13 is provided with a wire passing hole 14, and the wire harness of the ceiling machine passes through the wire passing hole 14 and extends out of the outside of the baffle 13. The disordered wire harness can be regularized, the arrangement of the wire harness is facilitated, the wire harnesses are prevented from being entangled with each other, and the wire harness extending out of the outside of the baffle 13 facilitates plugging and unplugging of the wire harness outside the bottom plate, and reduces the operation difficulty. The wire passing hole 14 and the drain pipe connector 15 are arranged on the upper side and the lower side of the baffle 13 respectively, so as to prevent the distance between the two from being too close to affect the strength of the support 1. Arranging the drain pipe connector 15 and the wire passing hole 14 on the support 1 can make full use of the space of the support 1, without changing the water pump assembly, the bottom plate and the support.

[0065] Specifically, the support 1 further comprises a reinforcing rib 16 for improving the overall strength of the support 1.
