Problems solved by technology

Although it can reduce the waiting time for warm-up, it takes a certain amount of time from the start of the water pump to the completion of heating, and consumes some gas energy and electric energy. At the same time, the long heating time will consume more gas energy and electric energy.

Embodiment 1

[0035] In this example, if figure 1 As shown, an energy-saving gas water heater with a preheating function includes: a casing 110, and inside the casing 110, a heat exchanger 112, a smart cabin combustion chamber 113, a DC brushless fan 114 and a gas proportional Valve 117; hot water inlet 119, gas inlet 122 and cold water inlet 120 are provided at the bottom of the housing 110; a switching power supply 111 for controlling the switch of the water heater is also provided inside the housing 110; an intelligent control device is also provided inside the housing 110 device 115, circulating water pump 118, ambient temperature sensor 121, and return water temperature sensor 116; the bottom of the housing 110 is provided with a return water inlet 123; the intelligent controller 115 is connected to the circulating water pump 118, ambient temperature sensor 121, Return water temperature sensor 116, switching power supply 111, smart cabin combustion chamber 113, gas proportional valve 1...

Embodiment 2

[0039] In this example, if figure 2 As shown, a heating system of an energy-saving gas water heater with a preheating function, the system includes: an energy-saving gas water heater 1, a gas source 3 connected to the gas inlet 122 of the energy-saving gas water heater 1, and a gas source 3 connected to the cold water inlet 120 of the energy-saving gas water heater 1 The cold water pipe 5 and the hot water pipe 4 connected with the hot water outlet of the energy-saving gas water heater.

[0040] As an optimized solution, a one-way valve 2 is arranged on the return water pipe, so that the water in the return water pipe 6 can only flow from the water pipe to the energy-saving gas water heater 1 .

[0041] With the above technical solution, the return pipe 6 and the hot water pipe 4 are connected through the energy-saving gas water heater 1 to form a circuit.

Embodiment 3

[0043] In this example, if image 3 Shown: a heating method for a heating system of an energy-saving gas water heater with a heating function, said method comprising:

[0044]Step 1: Determine the starting temperature of the circulating water pump 118 of the energy-saving gas water heater 1 according to the ambient temperature;

[0045] Step 2: The circulating water pump 118 of the energy-saving gas water heater 1 pumps water back through the return pipe 6, and detects the temperature of the return water;

[0046] Step 3: When the return water temperature is lower than the starting temperature of the circulating water pump 118, start the circulating water pump 118;

[0047] Step 4: The energy-saving gas water heater 1 starts to heat up the water to the preset temperature;

[0048] Step 5: The circulating water pump 118 of the energy-saving gas water heater 1 pumps water back through the return pipe 6, and detects the temperature of the return water;

[0049] Step 6: When th...

Abstract

The invention discloses an energy-saving gas water heater with the preheating function and a heating system and method. The water heater comprises a shell; a heat exchanger, an intelligent cabin combustion chamber, a direct-current brushless fan and a gas proportional valve are sequentially arranged in the shell from top to bottom; a hot water inlet, a gas inlet and a cold water inlet are formed in the bottom of the shell; a switching power supply for controlling the on-off states of the water heater is further arranged in the shell; an intelligent controller, a circulating water pump, an environment temperature sensor and a return water temperature sensor are further arranged in the shell; a return water inlet is further formed in the bottom of the shell; and the intelligent controller isin signal connection with the circulating water pump, the environment temperature sensor, the return water temperature sensor, the switching power supply, the gas proportional valve and the direct-current brushless fan. The energy-saving gas water heater and the heating system and method have the advantages of being short in heating time and energy-saving.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an energy-saving gas water heater with a preheating function, a heating system and a method. Background technique [0002] Since household gas water heaters are generally installed on living balconies, while bathing water is in the bathroom, there is a long pipeline from the bathroom to the kitchen, generally between 10 and 30 meters. Therefore, when the user takes a bath, the cold water stored in the pipeline must first be released to have hot water flow out, and a lot of cold water must be released to provide hot water. Not to mention waiting for a long time, a lot of water is wasted. Especially when the weather turns cold and cold, the hot water will not come out for a long time. Therefore, it has become a ubiquitous problem in the gas water heater industry to solve the problem of putting cold water for a period of time before using hot water. [0003] In recent years,...
