Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning cleaning, in particular to a central air-conditioning cleaning sewage suction device. Background Technique

[0002] The central air conditioner refers to a large air-conditioning system, which consists of a host and terminals. The host is divided into a water-cooled unit and an air-cooled unit. The terminal equipment mainly consists of an air-conditioning unit and a fan coil unit. There is also a refrigerant Freon VRV air-conditioning unit for the central air conditioner, which is different from ordinary household air conditioners and can be used in large-scale buildings.

[0003] At present, after the inner unit of the household central air conditioner is used for a long time, it is necessary to clean the fan blades of the inner unit to increase the air discharge volume of the inner unit. After the fan blades are rinsed, the sewage will flow inside the fan blade housing directly below. Therefore, a sewage suction device is needed to remove the sewage. However, when the existing sewage suction devices are in use, most of them directly insert a hose into the inside of the fan blade housing for sewage suction. However, the material of the hose is relatively soft, and the water suction port is prone to bending and not reaching the lowest point after entering the inside of the fan blade housing, and the external staff cannot see the specific position of the hose clearly, resulting in sewage remaining inside the fan blade housing easily during sewage suction, with poor cleaning effect, and more sewage will affect the normal rotation of the fan blades;

[0004] At the same time, after the existing devices are used, most of them do not have a structure for storing and accommodating the hose. The hose is placed together with other tools, which will not only cause the hose to be damaged, but also easily cause the hose to be knotted and excessively bent, reducing the service life of the hose. Content of the Utility Model

The water inlet of the small self-priming pump is communicated with a connecting pipe. One end of the connecting pipe is communicated with an installation pipe designed as a J shape, and the other end of the installation pipe is communicated with a sewage suction pipe;

[0008] A bearing fixed to one side of the surface of the installation pipe. A connecting plate is fixedly connected to the surface of the bearing. A positioning mechanism is installed on the surface of the connecting plate. A storage box is fixedly connected to the top of the installation shell. One side of the storage box is hinged with a box cover. A lock is installed on one side of the box cover. A protective pad is fixedly connected to the bottom of the inner cavity of the storage box.

[0009] Preferably, the positioning mechanism includes a positioning rod sliding on the connecting plate and a connecting disk fixed to one end thereof, and further includes a tension spring fixed to one side of the connecting disk and a positioning block fixed to one end of the positioning rod.

[0010] Preferably, the positioning block is made of rubber material, and the position of the positioning block corresponds to that of the sewage suction pipe.

[0011] Preferably, the connecting pipe is designed as a flexible pipe, and the surface of the connecting pipe is movably connected to the surface of the reel.

Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4As shown in the figure, a central air-conditioning cleaning and sewage suction device includes an installation shell 1. A small self-priming pump 2 is bolted inside the installation shell 1. The water outlet of the small self-priming pump 2 is communicated with a sewage discharge pipe 3. One end of the sewage discharge pipe 3 penetrates to the outside of the installation shell 1. Under the action of the installation shell 1, the small self-priming pump 2 can be protected to avoid being easily damaged by contacting foreign objects. With the cooperation of the sewage discharge pipe 3, sewage can be discharged from the inside of the installation shell 1. A reel 4 is installed on one side of the installation shell 1. The water inlet of the small self-priming pump 2 is communicated with a connecting pipe 5. The connecting pipe 5 is designed as a flexible pipe. The surface of the connecting pipe 5 is movably connected with the surface of the reel 4. Under the action of the reel 4, the connecting pipe 5 can be stored, so that the connecting pipes 5 will not be entangled with each other when the device is not in use. One end of the connecting pipe 5 is communicated with an installation pipe 6. The installation pipe 6 is designed in a J shape. The other end of the installation pipe 6 is communicated with a sewage suction pipe 7. The installation pipe 6 and the sewage suction pipe 7 are used in cooperation. Under this action, the sewage suction pipe 7 can extend into the inside of the central air-conditioning fan blade housing with the cooperation of the installation pipe 6. With the cooperation of the small self-priming pump 2, the sewage inside the fan blade housing can pass through the inside of the sewage suction pipe 7 and the installation pipe 6 and then be discharged from one end of the sewage discharge pipe 3, so as to suck out the sewage inside the fan blade housing, which is convenient for the staff to maintain the central air-conditioning indoor unit. The sewage suction pipe 7 is designed in a T-shaped structure, and both sides of the sewage suction pipe 7 have water inlets. Under this action, after the sewage suction pipe 7 enters the inside of the fan blade housing, it can suck the sewage on both sides at the same time, which not only improves the sewage suction efficiency, but also is convenient for sucking the sewage inside the fan blade housing. One side of the surface of the installation pipe 6 is fixedly connected with a bearing 8. The surface of the bearing 8 is fixedly connected with a connecting plate 10. A positioning mechanism 9 is installed on the surface of the connecting plate 10. Under the action of the positioning mechanism 9, the bottom of the fan blade housing can be squeezed, so that the sewage suction pipe 7 can contact the bottom of the inner cavity of the fan blade housing, so that the sewage inside the fan blade housing can be discharged more thoroughly. With the cooperation of the bearing 8 and the connecting plate 10, it can avoid the positioning mechanism 9 from causing obstruction when the sewage suction pipe 7 is put into the fan blade housing, making it more convenient to put the sewage suction pipe 7 into the fan blade housing. The top of the installation shell 1 is fixedly connected with a storage box 11. One side of the storage box 11 is hinged with a box cover 12. With the cooperation of the storage box 11 and the box cover 12, when the device is not in use, the installation pipe 6 and the parts on its surface can be stored to avoid the installation pipe 6 and the sewage suction pipe 7 from being bent after being squeezed. A lock 14 is installed on one side of the box cover 12. The lock 14 and the storage box 11 are used in cooperation. Under this action, the box cover 12 can be limited so that it will not move easily. The bottom of the inner cavity of the storage box 11 is fixedly connected with a protective pad 13. The protective pad 13 is made of flexible material, and the surface of the protective pad 13 is fixedly connected with the inner wall of the storage box 11. Under this action, the positioning mechanism 9 and the connecting plate 10 can be embedded into the protective pad 13 after being squeezed by the box cover 12, so that the installation pipe 6 and the parts on its surface will not move easily, effectively improving the protection effect on the parts.

[0023] The positioning mechanism 9 includes a positioning rod 91. One side of the positioning rod 91 penetrates to the other end of the connecting plate 10 and is slidably connected to the inner wall at the penetration point. One end of the positioning rod 91 is fixedly connected with a connecting disc 93. One side of the connecting disc 93 is fixedly connected with a tension spring 92. The other end of the tension spring 92 is fixedly connected to the surface of the connecting plate 10. One end of the positioning rod 91 is fixedly connected with a positioning block 94. In this way, when the sewage suction pipe 7 is inserted into the interior of the fan blade housing, the tension spring 92 will make the positioning rod 91 contact the surface of the fan blade housing. Then, under the action of the tension spring 92, the connecting plate 10 will drive the mounting pipe 6 and the sewage suction pipe 7 to move through the bearing 8, so that the sewage suction pipe 7 can be attached to the bottom of the inner cavity of the fan blade housing, thereby facilitating the complete suction of the sewage inside the fan blade housing. The positioning block 94 is made of rubber, and the position of the positioning block 94 corresponds to that of the sewage suction pipe 7. The material can increase the friction between the positioning block 94 and the fan blade housing, so that the sewage suction pipe 7 can be more stable during sewage suction. And under the action of the position, the staff can accurately obtain the position of the sewage suction pipe 7, so as to facilitate the adjustment of the position of the sewage suction pipe 7.

[0024] It should be noted that the technical features such as the small self-priming pump 2 and the reel 4 proposed in this technical solution should be regarded as the prior art, and the specific structure of the reel 4 is the same as the storage structure of the tape measure. The specific structure, working principle, and possible control methods and spatial layout methods involved in these technical features can be selected conventionally in this field, and this technical solution will not be further elaborated specifically.

[0025] Working principle: First, take out the mounting pipe 6 and the parts on its surface, then rotate the connecting plate 10 by 180 degrees, then insert the sewage suction pipe 7 into the interior of the fan blade housing, then rotate the connecting plate 10 to drive the parts on its surface back to the original position. Then the staff pulls the connecting disc 93 to drive the positioning block 94 to move through the positioning rod 91, moves the positioning block 94 to the lower part of the surface of the fan blade housing, and then releases the connecting disc 93. Under the action of the tension spring 92, the positioning block 94 can be attached to the fan blade housing, so that the mounting pipe 6 drives the sewage suction pipe 7 to move, so that the water inlet of the sewage suction pipe 7 can contact the bottom of the inner cavity of the fan blade housing. Then the staff turns on the small self-priming pump 2. Under the action of the small self-priming pump 2, the sewage inside the fan blade housing is sucked out and discharged from the sewage discharge pipe 3. After the sewage suction is completed in sequence, the staff rotates the connecting plate 10 by 180 degrees, then takes out the sewage suction pipe 7 from the interior of the fan blade housing and puts it back into the storage box 11 again. And under the action of the reel 4, the connecting pipe 5 can be wound up to avoid the situation of knotting and mutual entanglement of the connecting pipe 5.
