Embodiment 1

[0036] like figure 1 , figure 2 Shown is a cruising sterilization method for hot water equipment, which uses a circulating water pump to realize the water circulation of the water pipeline of the hot water equipment, uses an ultraviolet sterilizer to sterilize the water flow in the water pipeline, and uses a main controller to control the circulation The water pump and the ultraviolet sterilizer work; during sterilization, at least one of the following sterilization methods is included: 1) at the set time point, the circulating water pump and the ultraviolet sterilizer are controlled to run simultaneously for a first duration; 2) In the set time period, control the circulating water pump and the ultraviolet sterilizer to run simultaneously for a second duration every time interval; 3) Manually control the circulation of the circulating water pump and the ultraviolet sterilizer through the sterilization key Start and stop at the same time.

[0037] The manipulator connected ...

Embodiment 2

[0045] like image 3As shown, a hot water equipment includes: a water heater 1, a preheating circulation pipeline 2 connected to the water heater 1, and a circulating water pump 3 connected to the preheating circulation pipeline 2; The preheating circulation pipeline 2 is also provided with an ultraviolet sterilizer 4, and the circulating water pump 3 and the ultraviolet sterilizer 4 work simultaneously to sterilize under the control of the controller. The sterilizing method is as described in the first embodiment.

[0046] Wherein, the water heater 1 is a gas water heater, and the circulating water pump 3 , the ultraviolet sterilizer 4 and the controller 5 form an independent module 6 , and the module 6 is connected to the circulating pipeline 2 . By setting up an independent module, it can be used in combination with any hot water equipment that requires sterilization without changing the configuration of the original hot water equipment. It is easy to install and maintain, ...

Embodiment 3

[0048] like Figure 4 As shown, a hot water device, the structure of which is basically the same as that of Embodiment 2, the difference is that the circulating water pump 3 is arranged inside the gas water heater 1, and the ultraviolet sterilizer 4 is arranged outside the gas water heater 1, The controller is the main controller 7 of the gas water heater.

[0049] like Figure 5 As shown, as an alternative implementation of this embodiment, the circulating water pump 3 and the ultraviolet sterilizing device 4 are both arranged in the gas water heater 1, which is more beautiful.

Abstract

The invention discloses a circulation sterilization method for a hot water device. The method is characterized in that a circulating water pump is utilized to realize water circulation of a water pipeof the hot water device, an ultraviolet sterilizer is utilized to sterilize a water flow in the water pipe, and a controller is utilized to control the circulating water pump and the ultraviolet sterilizer to work; and when sterilization is performed, the sterilization method comprises at least one of the following sterilization manners: 1) controlling the circulating water pump and the ultraviolet sterilizer to simultaneously operate for a first period of time at a set time point; 2) controlling the circulating water pump and the ultraviolet sterilizer to operate simultaneously for a secondperiod of time every interval time during a set period of time; and 3) manually controlling the circulating water pump and the ultraviolet sterilizer to start and stop simultaneously by a manual sterilization button. According to the method provided by the invention, bacteria growing in a circulation pipeline can be effectively killed, so that a sanitary water flow in the circulation pipeline is ensured, and safety of use of water is improved. The invention also provides the hot water device.

Description

technical field [0001] The invention relates to the technical field of fluid heaters, in particular to a cruising sterilization method for hot water equipment and the hot water equipment. Background technique [0002] Hot water equipment with a hot water circulation device usually uses a water pump as the circulating power to heat the water in the pipeline in advance, so that hot water flows out immediately when the user turns on the tap. This kind of hot water equipment generally has the functions of single preheating and reservation. Come to the following questions: [0003] 1) Because the living temperature of bacteria such as E. coli and Salmonella is close to the temperature of the human body, it is easy to breed E. coli and Salmonella in the pipeline after the preheating is completed or during the scheduled time period. However, most users have no water demand from 23:00 in the evening to 6:00 in the morning, which provides time for bacteria to breed, affects the wat...
