Problems solved by technology

[0002] In the existing gas-fired instant water heaters, the temperature of the outlet water is easily changed by the fluctuation of the water pressure, especially when the user switches the machine on and off during bathing (flush after using the shower gel), there will inevitably be a section of cold water when the machine is restarted, and this section of cold water often Due to different installations by users, it is impossible to judge the timing of arrival, resulting in sudden cold water during the bathing process of users, which seriously affects the comfort of bathing
[0003] For the hot and cold problem of the outlet water temperature of the gas instant water heater, the following two methods are mainly used to solve the problem in the prior art: one is to increase the circulation pipeline, and at the same time, it needs to be equipped with a water pump, which is complex in structure, inconvenient to install, and very expensive. Unacceptable to ordinary users
One is to add a water tank to the outlet of the water heater. Since the cold water in the water tank needs to be drained in advance, not only the heating speed is slow, but also it will cause waste of water resources.

Embodiment 1

[0030] Such as figure 1 , figure 2 As shown, a gas water heater constant temperature device 1 is installed on the water outlet 21 of the gas water heater 2, including: a diverter valve 11 connected to the water outlet 21 of the gas water heater 2, and two water outlet branches connected to the diverter valve 11 respectively. The water storage tank 12 , the cut-off valve 13 , and the controller 14 used to control the openings of the two branches of the diverter valve 11 ;

[0031] During actual operation, part of the hot water flowing out from the gas water heater flows into the water storage tank 12 , and part of it is directly discharged from the hot water outlet 3 through the shut-off valve 13 . When starting to use the water heater, distribute 10% of the total amount of hot water to the branch of the water storage tank, and at the same time, the shut-off valve 4 is in an open state, so that the hot water can quickly reach the hot water outlet 6, and the hot water can be u...

Embodiment 2

[0038] Such as image 3 As shown, the gas water heater thermostat provided in this embodiment is basically the same as that in Embodiment 1, the difference is that a temperature sensor 16 connected to a controller 14 is provided on the water outlet of the water storage tank 12 .

[0039] During actual work, when the temperature detected by the temperature sensor 16 exceeds the set temperature by 1, the shut-off valve 13 is closed, and the opening of the branch of the water storage tank of the diverter valve 11 is adjusted to the maximum, and all the hot water will pass through the branch of the water storage tank to reach the hot water. Water outlet 3; When the temperature detected by the temperature sensor 16 is lower than the set temperature two, the shut-off valve 13 is opened, so as to avoid the water outlet temperature of the hot water outlet 3 being too low, and also avoiding the heating time being too long when the water heater is used next time.

Abstract

The invention discloses a thermostat of a gas water heater. The thermostat of the gas water heater is arranged on a water outlet of the gas water heater and comprises a flow distributing valve, a water storage tank, a stop valve and a controller, wherein the flow distributing valve is connected with the water outlet of the gas water heater; the water storage tank and the stop valve are respectively connected with two water draining branches of the flow distributing valve; the controller is used for controlling the opening degree of the two branches of the flow distributing valve; and the water storage tank and the water outlet of the stop valve form a hot water outlet jointly. Compared with the prior art, the thermostat of the gas water heater has the advantages that the starting and heating speed is increased, and the circumstance that water is cold or hot irregularly due to water stopping temperature rise and water pressure fluctuation in a hot water using process is avoided. The invention also provides a constant-temperature water drainage control method of the gas water heater.

Description

technical field [0001] The invention relates to the technical field of fluid heaters, in particular to a gas water heater constant temperature device and a constant temperature outlet water control method. Background technique [0002] In the existing gas-fired instant water heaters, the temperature of the outlet water is easily changed by the fluctuation of the water pressure, especially when the user switches the machine on and off during bathing (flush after using the shower gel), there will inevitably be a section of cold water when the machine is restarted, and this section of cold water often Due to different installations by users, it is impossible to judge the timing of arrival, resulting in sudden cold water in the bathing process of users, which seriously affects the comfort of bathing. [0003] For the hot and cold problem of the outlet water temperature of the gas instant water heater, the following two methods are mainly used to solve the problem in the prior ar...
