Description

Technical Field

[0002] Power water heating equipment is a kind of equipment that inputs water into the inside of the pump body, collides and rubs against the high-speed rotating rotor inside the pump body, and then heats the water. In order to improve the heat generation efficiency of the pump body to water, the speed of the rotor inside the pump body is generally controlled by an external frequency converter. However, when the frequency converter controls the speed of the rotor inside the pump body, the pump body will generate a certain low-frequency noise, which is not conducive to the overall quietness control of the equipment. Therefore, we proposed a noise reduction structure of power water heating equipment to solve the above problems. Utility Model Content

[0026] The heat dissipation sleeve 3 has a hollow structure inside, and an upper water pipe connection end 301 and an outlet water pipe connection end 302 are fixedly installed on the outer wall of the heat dissipation sleeve 3, and the upper water pipe connection end 301 and the outlet water pipe connection end 302 both penetrate to the outside of the shell 4; a plurality of ventilation channels 303 are also provided in the longitudinal direction inside the heat dissipation sleeve 3, and the inside of the ventilation channels 303 is not connected with the inside of the heat dissipation sleeve 3, and ventilation avoidance holes are provided inside the cover plate 5 and at the bottom of the shell 4 at the positions of the plurality of ventilation channels 303. Hole 501; a water inlet 101 and a water outlet 102 are provided on the power hot water pump body 1, and a circular hole 1 402 and a circular hole 2 403 are provided on the heat dissipation sleeve 3 and the outer shell 4 at the positions corresponding to the water inlet 101 and the water outlet 102, and the circular hole 1 402 and the circular hole 2 403 located on the heat dissipation sleeve 3 are not connected to the inside of the heat dissipation sleeve 3; the water inlet 101 and the water outlet 102 are fixedly installed with a water pipe joint 103 through the corresponding circular hole 1 402 and the circular hole 2 403.

[0027] The noise reduction process of the noise reduction structure of this kind of power hydrothermal equipment is as follows:

[0028] When the power hot water pump body 1 is powered on and operated, and is affected by the inverter control, the power hot water pump body 1 will generate a certain amount of low-frequency noise. At this time, the noise inside the shell 4 is absorbed by the noise reduction inner sleeve 2, reducing the risk of noise propagation outwards. In addition, since the shell 4 and the cover plate 5 are fixedly installed to form a relatively sealed environment, the risk of low-frequency noise of the power hot water pump body 1 overflowing outwards is reduced.

[0029] The heat dissipation principle of the noise reduction structure of this kind of power hydrothermal equipment is:

[0030] Since the power hot water pump body 1 is installed inside the housing 4, a certain amount of heat will be generated during long-term operation. At this time, the heat will be transferred to the heat dissipation sleeve 3 to heat the heat dissipation sleeve 3. At this time, the water pipe used for heat dissipation is connected through the upper water pipe connection end 301. After the water enters the heat dissipation sleeve 3, it is discharged through the outlet water pipe connection end 302, taking away the heat transferred to the heat dissipation sleeve 3, thereby achieving the effect of cooling the power hot water pump body 1;

[0031] At the same time, in order to assist the heat dissipation of the heat dissipation sleeve 3, the driving motor 7 inside the base 6 is started and the heat dissipation fan 8 rotates, forming a blowing effect at the bottom of the shell 4, and the blown wind first enters the ventilation channel 303 of the heat dissipation sleeve 3 through the ventilation avoidance hole 501 at the bottom of the shell 4, and then is discharged through the ventilation avoidance hole 501 inside the cover plate 5, so that the wind can flow inside the ventilation channel 303 of the heat dissipation sleeve 3, thereby improving the heat dissipation efficiency of the heat dissipation sleeve 3 and reducing the risk of high-temperature damage to the pump body 1 of the power hot water pump.

[0032] Embodiment 2:

[0033] In view of the above embodiment 1, for further description, refer to Figure 3 and Figure 4 The noise reduction inner sleeve 2 is a tubular structure made of sound-absorbing sponge material, and a plurality of sound-absorbing flanges 201 are evenly spaced on the inner wall of the noise reduction inner sleeve 2 .

[0034] By providing a plurality of sound-absorbing flanges 201, the contact area of ​​the noise-reducing inner sleeve 2 can be increased, which is beneficial to absorbing the noise generated by the power hot water pump body 1; through the installed water pipe joint 103, the water to be heated can enter the power hot water pump body 1 through the water inlet 101, and then be discharged through the water outlet 102;

[0035] By designing that the interior of the ventilation channel 303 is not connected to the interior of the heat dissipation sleeve 3, and the circular hole 1 402 and the circular hole 2 403 located on the heat dissipation sleeve 3 are not connected to the interior of the heat dissipation sleeve 3, it is possible to prevent water inside the heat dissipation sleeve 3 from flowing out through the ventilation channel 303 and flowing out through the circular hole 1 402 and the circular hole 2 403 located on the heat dissipation sleeve 3, thereby avoiding affecting the heat dissipation and the overall sealing.

[0036] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
