Detailed implementation manners

[0027] The principles and features of the present application will be described below with reference to the accompanying drawings. The examples given are only used to explain the present application and are not intended to limit the scope of the present application.

[0028] As Figures 1 to 11 shown, the ceiling-mounted air conditioner provided in the embodiment of the present application includes: a chassis 100 with an open end, and an installation opening 110 is provided on the peripheral wall of the chassis 100; and a water pump module 200, the water pump module 200 includes a water pump assembly and a first mounting bracket 210, the first mounting bracket 210 is covered on the installation opening 110 from the outside of the chassis 100, and the water pump assembly is located inside the chassis 100 and is fixed to the first mounting bracket 210; wherein, the first mounting bracket 210 is configured to be disassembled and assembled with the peripheral wall of the chassis 100 from the outside of the chassis 100, the water pump assembly is configured to be able to pass through the installation opening 110, and the water pump assembly is further configured to be able to be disassembled and assembled from the opening of the chassis 100 to be separated from and connected to the first mounting bracket 210.

[0029] The ceiling-mounted air conditioner is installed on the indoor suspended ceiling 300: As Figure 2 , Figure 3 , Figures 5 to 7 , Figure 12 shown, if the indoor suspended ceiling 300 is provided with a maintenance opening 310, when the water pump 230 is damaged, the maintenance opening 310 is opened, and the first mounting bracket 210 is removed from the maintenance opening 310. In this process, the first mounting bracket 210 will take out the water pump assembly from the installation opening 110 (as Figure 6 and Figure 7As shown, one end of the first mounting bracket 210 away from the bottom wall of the chassis is inclined toward the radial outside of the chassis, so that the first mounting bracket 210 can take out the water pump assembly from the mounting opening 110), and then remove the water pump 230 of the water pump assembly from the first mounting bracket 210. At this time, the operator can replace the water pump 230; as Figures 8 to 11 、 Figure 13 As shown, if the indoor ceiling 300 is not provided with a maintenance opening 310, when the water pump 230 is damaged, the water pump assembly is disassembled from the first mounting bracket 210 through the opening of the chassis 100 (the first mounting bracket 210 still remains fixed at the mounting 110 opening), and then the water pump assembly is taken out from the opening of the chassis 100. At this time, the operator can replace the water pump 230 of the water pump assembly; this ceiling machine is applicable to both the installation scenarios with and without the maintenance opening 310, and can replace the water pump 230 when the water pump 230 is damaged. Moreover, for the installation scenario with the maintenance opening 310, the maintenance and replacement process of the water pump 230 is simple.

[0030] In some examples, such as Figure 2 and Figure 4 As shown, an installation wall 211 protrudes from the side of the first mounting bracket 210 facing the inside of the chassis 100. The installation wall 211 extends into the chassis 100 from the mounting opening 110. The water pump assembly abuts against the installation wall 211, and the first screw 240 connects the water pump assembly and the installation wall 211 from the opening of the chassis 100 toward the bottom wall of the chassis 100. If the indoor ceiling 300 is not provided with a maintenance opening 310, when the water pump 230 is damaged, the first screw 240 is unscrewed from the opening of the chassis 100, and the water pump assembly can be taken out from the opening of the chassis 100. Among them, the water pump assembly is located on the side of the installation wall 211 facing away from the bottom wall of the chassis 100, which is more conducive to connecting the water pump assembly and the installation wall 211 together with the first screw 240.

[0031] In some embodiments, such as Figure 2 and Figure 4 As shown, the water pump assembly includes a water pump 230 and a second mounting bracket 220. The water pump 230 is fixed on the second mounting bracket 220. The first screw 240 is located between the water pump 230 and the first mounting bracket 210 and connects the second mounting bracket 220 and the installation wall 211 together. That is: the second mounting bracket 220 is provided with a through hole, the installation wall 211 is provided with a threaded hole, and the first screw 240 passes through the through hole from the opening of the chassis 100 toward the bottom wall of the chassis 100 and is screwed into the threaded hole to fix the second mounting bracket 220 on the installation wall 211. Preferably, the water pump 230 is fixed on the second mounting bracket 220 by a second screw 250. By unscrewing the second screw 250, the water pump 230 can be disassembled from the second mounting bracket 220. The first mounting bracket 210 is fixed on the peripheral wall of the chassis 100 by a third screw 260 screwed from the outside of the chassis 100 toward the inside of the chassis.

[0032] In some embodiments, the mounting wall 211 is provided with a positioning portion, and the second mounting bracket 220 is provided with a mating portion. The positioning portion and the mating portion cooperate with each other to pre-position the second mounting bracket 220 on the mounting wall 211. At this time, the through hole and the screw hole are aligned. This solution can effectively improve the assembly efficiency of the second mounting bracket 220 and the mounting wall 211.

[0033] It can be that the positioning portion is set as a hook, and the positioning and mating portion is set as a mating hole. The hook extends into the mating hole and is hooked on the outer end face of the mating hole; or it can be that the positioning portion is set as a mating hole, and the positioning and mating portion is set as a hook. The hook extends into the mating hole and is hooked on the outer end face of the mating hole, etc. The above can all achieve the purpose of the present application, and its gist does not depart from the design concept of the present utility model, so it will not be elaborated here and should all fall within the protection scope of the present application.

[0034] In some examples, such as Figure 3 and Figure 7 shown, the ceiling air conditioner further includes: a corrugated pipe 400. A drain pipe 120 is provided on the peripheral wall of the chassis 100. The corrugated pipe 400 is located inside the chassis 100. One end of the corrugated pipe 400 is connected to the water outlet of the water pump 230 through a clamp 410, and the other end is connected to the water inlet of the drain pipe 120 through a clamp.

[0035] As Figures 5 to 7 , Figure 12 shown, if the indoor ceiling 300 is provided with a maintenance opening 310, then when the water pump 230 is damaged, the maintenance opening 310 is opened, and the first mounting bracket 210 is removed from the maintenance opening 310. During this process, the first mounting bracket 210 will take out the water pump assembly from the mounting opening 110, and the corrugated pipe 400 will be stretched. Then, the corrugated pipe 400 is disassembled at the water outlet of the water pump 230 and the water pump 230 is disassembled from the second mounting bracket 220. At this time, the operator can replace the water pump 230. After the water pump 230 is replaced and the water pump assembly and the first mounting bracket 210 are installed, the corrugated pipe 400 will shorten automatically under the action of its own elastic force. Therefore, this solution makes the space occupied by the corrugated pipe 400 inside the chassis 100 smaller.

[0036] Furthermore, as Figure 1 and Figure 3 shown, the ceiling air conditioner further includes: an open-ring heat exchanger 500. The heat exchanger 500 is arranged inside the chassis 100. The opening of the heat exchanger 500 faces the first corner of the peripheral wall of the chassis 100. The water pump assembly is located at the first corner. An installation opening 110 is provided on the first side wall at the first corner, and a refrigerant inlet and outlet pipe 130 and a drain pipe 120 are provided on the second side wall at the first corner. In this solution, the water pump assembly, the corrugated pipe 400, the refrigerant inlet and outlet pipe 130 and the drain pipe 120 basically do not affect the air duct of the ceiling air conditioner. As Figures 8 to 11 ,Figure 13 As shown, if the indoor ceiling 300 is not provided with a maintenance opening 310, when the water pump 230 is damaged, the first screw 240 can be unscrewed from the opening of the chassis 100, and the water pump assembly can be taken out from the opening of the chassis 100. This process does not require the disassembly of the heat exchanger 500. Among them, a blower 1000 is provided inside the heat exchanger 500.

[0037] Furthermore, as Figure 1 、 Figure 2 、 Figures 8 to 10 shown, the ceiling-mounted air conditioner further includes: a water receiving tray 600, which is arranged at the opening of the chassis 100; and an electric control box 700, which is arranged on one side of the bottom wall of the water receiving tray 600 facing away from the chassis 100 and is electrically connected to the water pump 230. Among them, a wind guide ring 800 and a panel 900 are further installed on one side of the bottom wall of the water receiving tray 600 facing away from the chassis 100. As Figures 8 to 11 、 Figure 13 shown, if the indoor ceiling 300 is not provided with a maintenance opening 310, when the water pump 230 is damaged, first remove the panel 900, the electric control box 700, the wind guide ring 800 and the water receiving tray 600 in sequence, and then unscrew the first screw 240 from the opening of the chassis 100, and the water pump assembly can be taken out from the opening of the chassis 100. This process does not require the disassembly of the heat exchanger 500. Among them, the electric control box 700 includes an electric control box body 710 and an electric control box cover 720. The electric control box body 710 is installed on the water receiving tray 600, and the electric control box cover 720 is covered on the electric control box body 710.

[0038] Furthermore, as Figure 4 and Figure 5 shown, the water pump assembly is provided with a first connection line 231, the first connection line 231 has a first docking terminal, the electric control box 700 has a second connection line 730, the second connection line 730 has a second docking terminal, the second connection line 730 bypasses the water receiving tray 600 to make the second docking terminal extend to the installation opening 110, and the first docking terminal and the second docking terminal can be disassembled and assembled from the installation opening 110.

[0039] As Figures 5 to 7 、 Figure 12As shown, if the indoor ceiling 300 is provided with an inspection opening 310, when the water pump 230 is damaged, open the inspection opening 310, remove the first mounting bracket 210 from the inspection opening 310. During this process, the first mounting bracket 210 will take out the water pump assembly from the mounting opening 110, and the bellows 400 will be stretched. Then, disconnect the first docking terminal and the second docking terminal at the mounting opening 110, and then remove the bellows 400 at the water outlet of the water pump 230 and remove the water pump 230 from the second mounting bracket 220. At this time, the operator can replace the water pump 230. After the water pump 230 is replaced, the first docking terminal and the second docking terminal are inserted together. After the water pump module 200 is installed on the chassis, the bellows 400 will shorten by itself under the action of its own elastic force, so that the space occupied by the bellows 400 inside the chassis 100 is smaller.

[0040] As Figures 8 to 11 , Figure 13 shown, if the indoor ceiling 300 is not provided with an inspection opening 310, when the water pump 230 is damaged, first remove the panel 900, the electric control box cover 720, the plug-in terminal inserted in the electric control box body 710 (the second connection line 730 is connected to the circuit board inside the electric control box body 710 through a plug-in terminal), the electric control box body 710, the air guide ring 800 and the water receiving tray 600 in sequence, and then unscrew the first screw 240 from the opening of the chassis 100, then the water pump assembly can be taken out from the opening of the chassis 100, and then remove the bellows 400 at the water outlet of the water pump 230 and remove the water pump 230 from the second mounting bracket 220.

[0041] Furthermore, as Figure 4 and Figure 5 shown, the first mounting bracket 210 is provided with a first wire clamping structure 212, and the first connection line 231 is arranged in the first wire clamping structure 212 to realize the wiring of the first connection line 231; the water receiving tray 600 is provided with a second wire clamping structure 610, and the second connection line 730 is arranged in the second wire clamping structure 610 to realize the wiring of the second connection line 730.

[0042] Among them, as Figure 4 and Figure 5 shown, both the first wire clamping structure 212 and the second wire clamping structure 610 are set as wire clamping grooves. This solution has a simple structure and convenient wire clamping operation.

[0043] The air conditioner (not shown in the figure) provided by the embodiment of the present application includes the ceiling machine described in any of the above embodiments.

[0044] This air conditioner has all the advantages of the ceiling machine provided by any of the above embodiments, and will not be elaborated here.
