Description

Technical Field

[0001] The present invention relates to the technical field of hot water systems, and specifically to an energy-saving hot water device. Background Art

[0002] The boiling water system is a facility that provides continuous and safe boiling water for public places (such as schools, hospitals, office buildings, etc.). Its core function is to heat tap water to boiling (100 °C) to meet drinking or disinfection needs.

[0003] The system is generally divided into two categories: storage type (using a heat preservation water tank to store boiling water) and instant heating type (heating instantaneously as needed). The former is suitable for centralized water supply, and the latter is energy-saving and avoids repeated heating. The boiling water system is widely used in scenarios that require high-temperature water, ensuring water use safety through standardized design and reducing the inconvenience and energy consumption of traditional boiling water methods.

[0004] In the prior art, in an instant hot water system, water is generally heated to boiling and then flows out from the water outlet. If the user does not want boiling water, unnecessary energy consumption will occur and it will affect the use; if water at a specific temperature is required, more components are needed for temperature control, the temperature control components are complex, and the energy consumption is high.

[0005] In view of this, the present invention provides an energy-saving hot water device to solve the problems raised in the above background art. Summary of the Invention

[0006] Through a hot water circulation heating device, the present invention can accurately control the temperature of the water outlet, has a simple structure, and no energy waste will occur during this period. Based on this, the present invention is completed.

[0007] The present invention provides an energy-saving hot water device, including a water purification and filtration device 1 and an instant heating device 2 connected to the water purification and filtration device 1 through a pipeline. The water purification and filtration device 1 and the instant heating device 2 are connected through a first pipeline 7. An inlet 6 is provided on the water purification and filtration device 1 to access tap water, and filtration is carried out inside the water purification and filtration device 1. The filtered water enters the instant heating device 2 through an electric valve 9 for heating. One end of the instant heating device 2 is provided with a water outlet 5, and a water temperature sensing controller and circulation device 4 is provided on the pipeline after the water outlet 5 to detect whether the water temperature flowing out of the instant heating device 2 reaches the set value. A second pipeline 8 is provided on the water temperature sensing controller and circulation device 4, and the second pipeline 8 is connected to the first pipeline 7.

[0008] Further, when the temperature of the water flowing out of the instant heating device 2 reaches the temperature set in the water temperature sensing controller and circulation device 4, it flows out from the water outlet 5 via the water temperature sensing controller and circulation device 4; when the temperature of the water flowing out of the instant heating device 2 does not reach the temperature set in the water temperature sensing controller and circulation device 4, the electric valve 9 closes, and the water flows through the water temperature sensing controller and circulation device 4 and the second pipeline 8 into the instant heating device 2 for reheating. During this process, the water temperature sensing controller and circulation device 4 provides power to the water; this process is repeated until the temperature of the water flowing out of the instant heating device 2 reaches the temperature set in the water temperature sensing controller and circulation device 4 and then flows out from the water outlet 5. During this period, the water temperature sensing controller and circulation device 4 controls the flow direction of the water; a one-way valve 3 is provided on the water temperature sensing controller and circulation device 4 and the second pipeline to prevent the water filtered by the water purification filtration device 1 from flowing to the water temperature sensing controller and circulation device 4, and at the same time prevent the heated water from flowing into the water purification filtration device 1, resulting in energy waste.

[0009] Further, the water purification filtration device 1, the instant heating device 2, and the water temperature sensing controller and circulation device 4 are connected to an external power supply to achieve power supply.

[0010] Compared with the prior art, the technical advantages of an energy-saving hot water device provided by the present invention are as follows:

[0011] An energy-saving hot water device provided by the present invention heats water through the instant heating device 2, and the heated water is detected and its flow direction is controlled by the water temperature sensing controller and circulation device 4. It can accurately control the temperature of the outlet water, can constantly output hot water at the required temperature, and avoids energy loss; by providing a one-way valve 3 on the pipeline connecting the water temperature sensing controller and circulation device 4, the water purification filtration device 1, and the pipeline between the water purification filtration device 1, it prevents the hot water from flowing into the water purification filtration device 1, resulting in energy waste.
