Technical Field

[0001] The utility model relates to the technical field of hot water pumps, in particular to a circulating hot water pump with a heat preservation function. Background Art

[0002] A circulating hot water pump is a mechanical device specially designed for hot water circulation system, usually called a hot water circulation pump. Its main function is to provide stable pressure and flow rate for the circulating heat carrier in the hot water circulation system, ensuring that the hot water can circulate continuously, safely and efficiently.

[0003] In the process of circulating hot water, the existing circulating hot water pumps often adopt insulation treatment such as wrapping insulation cotton on the pipes or using insulation sleeves. These insulation measures can reduce heat loss to a certain extent and improve the use effect of hot water. However, even if these insulation measures are taken, some heat of the hot water will inevitably be lost, resulting in poor insulation effect. Therefore, we propose a new type of circulating hot water pump with insulation function. Utility Model Content

[0011] Furthermore, a water outlet pipe is fixedly connected between the ends of the fourth connecting pipe and the second connecting pipe, a temperature sensor is arranged outside the water outlet pipe, and the temperature sensor is electrically connected to the controller.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, the water temperature can be monitored in real time by the temperature sensor, and the data can be sent to the controller.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a circulating hot water pump with a heat preservation function, including a pump 1, an input end of the pump 1 is fixedly connected to a water inlet pipe 11, an output end of the pump 1 is fixedly connected to a first connecting pipe 12, an outer surface of the first connecting pipe 12 is provided with a shell 2, a right surface of the shell 2 is provided with a second connecting hole 22, a left surface of the shell 2 is provided with a third connecting hole 23, a third connecting pipe 4 is fixedly installed inside the third connecting hole 23, an outer surface of the third connecting pipe 4 is provided with an inner shell 7, the interior of the inner shell 7 is in a cavity state, a heating wire 71 is provided inside the inner shell 7, a fourth connecting hole 72 is provided on the rear surface of the inner shell 7, the third connecting pipe 4 is fixedly installed inside the fourth connecting hole 72, a first connecting hole 21 is provided on the rear surface of the shell 2, and the first connecting pipe 12 is fixedly installed inside the first connecting hole 21.

[0023] The effect achieved by the entire embodiment 1 is that by connecting the water inlet pipe 11 to an external boiler or other heating equipment, by connecting the water outlet pipe 6 to an external heating device, by starting the pump 1, hot water is pumped to the first connecting pipe 12 through the water inlet pipe 11, and enters the interior of the housing 2 through the first connecting pipe 12, and the rotating shaft 25 is driven to rotate by the starting motor 24, thereby driving the adjusting plate 26 to rotate synchronously and change the angle of the adjusting plate 26, that is, to control the flow direction and flow rate of the hot water. When the hot water enters the water outlet pipe 6 through the second connecting pipe 3, the temperature sensor 61 can monitor the water temperature in real time and send the data to the controller 8. When the water temperature is low, by controlling the angle of the adjustment plate 26, the water flows through the third connecting pipe 4 into the inner cavity of the inner shell 7. Then, the water flow is heated by the heating wire 71 to increase the water temperature. The heated hot water enters the water outlet pipe 6 through the fourth connecting pipe 5 and reaches the heated equipment. In order to prevent excessive heat loss, an outer shell 74 is provided, and the gap between the outer shell 74 and the inner shell 7 is in a vacuum state, thereby reducing the medium for heat transfer to the outside and playing a role of heat preservation.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, a motor 24 is fixedly installed on the top of the shell 2, and a rotating shaft 25 is fixedly installed on the output end of the motor 24. The outer surface of the rotating shaft 25 passes through the top of the shell 2 and extends to the inside. An adjusting plate 26 is fixedly installed on the bottom end of the rotating shaft 25. A second connecting pipe 3 is fixedly installed inside the second connecting hole 22. A controller 8 is arranged at a position near the edge of the top of the shell 2, and the controller 8 is electrically connected to the motor 24. A fifth connecting hole 73 is opened on the front surface of the inner shell 7, and a fourth connecting pipe 5 is fixedly installed inside the fifth connecting hole 73. An outer shell 74 is sleeved on the outside of the inner shell 7. A water outlet pipe 6 is fixedly connected between the end of the fourth connecting pipe 5 and the second connecting pipe 3. A temperature sensor 61 is arranged on the outside of the water outlet pipe 6, and the temperature sensor 61 is electrically connected to the controller 8.

[0025] The effect achieved by the entire embodiment 2 is that the controller 8 can automatically control the angle of the adjustment plate 26, so that the water flow can flow from the second connecting pipe 3 and the third connecting pipe 4 at the same time. When the water flow converges at the water outlet pipe 6, the heated water is mixed with the hot water in the initial state, thereby automatically adjusting the water temperature.

[0026] Working principle: When in use, by connecting the water inlet pipe 11 to an external boiler or other heating equipment, by connecting the water outlet pipe 6 to an external heating equipment, by starting the pump 1, hot water is pumped into the first connecting pipe 12 through the water inlet pipe 11, and enters the interior of the shell 2 through the first connecting pipe 12, and the rotating shaft 25 is driven to rotate by the starting motor 24, thereby driving the adjustment plate 26 to rotate synchronously to change the angle of the adjustment plate 26, that is, to control the flow direction and flow of hot water. When the hot water enters the water outlet pipe 6 through the second connecting pipe 3, the water temperature can be monitored in real time through the temperature sensor 61, and the data can be sent to the controller 8. When the water temperature is low, the water can be circulated by controlling the angle of the adjustment plate 26. The water enters the inner cavity of the inner shell 7 through the third connecting pipe 4, and then the water flow is heated by the heating wire 71, so as to increase the water temperature. The heated hot water enters the water outlet pipe 6 through the fourth connecting pipe 5 and reaches the heated equipment. In order to prevent excessive heat loss, an outer shell 74 is provided, and the gap between the outer shell 74 and the inner shell 7 is in a vacuum state, so as to reduce the medium for heat transfer to the outside, thereby playing a role of heat preservation. At the same time, the angle of the adjustment plate 26 can be automatically controlled by the controller 8, so that the water flow can flow from the second connecting pipe 3 and the third connecting pipe 4 at the same time. When the water flow converges in the water outlet pipe 6, the heated water is mixed with the hot water in the initial state, so as to automatically adjust the water temperature.
