Embodiment Construction

[0048] The water temperature control method of the water heater provided by the present invention includes firstly setting a use temperature, then detecting a water inlet temperature and a water flow rate, then comparing the temperature difference between the water inlet temperature and the use temperature, and using the temperature difference as a reference to calculate The total calorific value required by the water flow to reach the use temperature, according to the calculated total calorific value, a gas supply for heating is provided per unit time, so that the incoming water is stably heated to the use temperature, and then When the outlet water temperature reaches the use temperature, the gas supply is immediately adjusted to a quantitative output to maintain a stable outlet water temperature.

[0049] The water temperature control device matched with the water temperature control method of the water heater includes a temperature setting device, a heater, a gas proportion...

Abstract

The invention relates to a water temperature control method and a water temperature control device for a water heater. The water temperature control device comprises a temperature setting device, a gas proportional valve, a heater, a temperature detector, a water volume detector and an operation controller. The water temperature control method comprises the following steps that: the temperature setting device sets use temperature before the water heater is used; the temperature detector and the water volume detector immediately detect water inlet temperature and water flow when the water heater begins to run; the operation controller compares the difference between the water inlet temperature and the use temperature, calculates a gross thermal value required by the water flow from the water inlet temperature to the use temperature, and controls the gas proportional valve according to the gross thermal value to adjust gas quantity supplied to the heater, make inlet water stably raised to the use temperature and discharged, and maintain the water outlet temperature for stabilizing the water heater.

Description

technical field [0001] The present invention is related to the water temperature control method and device of the water heater, and more specifically refers to a water heater water temperature control method and device thereof capable of maintaining a stable outlet water temperature. Background technique [0002] see figure 1 , is a well-known water heater water temperature control device for controlling the outlet water temperature of a water heater 500. The water heater 500 includes a water delivery pipe 510, a gas pipe 520 and a water temperature control device 530. The water delivery pipe 510 has a water inlet 511 and a water outlet 512 , the water temperature control device 530 includes a gas flow controller 531 , a heater 532 , a temperature detector 533 and an arithmetic controller 534 . [0003] The heater 532 is heated by the gas transported by the gas pipe 520 to the water in the water pipe 510, and the gas flow controller 531 is arranged on the gas conveying path...
