Instant heating type heating device

Abstract

The invention discloses an instant heating type heating device. The instant heating type heating device is connected to a water supply device. The water supply device is provided with a water supply unit and a main heating unit. The instant heating type heating device includes a body provided with a water holding chamber, a main control unit, a water inlet switch, a heating unit provided with a first heater and a second heater, a temperature control unit, a water outlet control valve, and a power supply unit; the heating unit is arranged in the water holding chamber of the body; when the temperature of water in the water holding chamber reaches a reference temperature value, the water outlet control valve is opened, and water runs; and until the water inlet temperature reaches a constant temperature valve, the main control unit controls the first heater and the second heater to heat water alternatively.

Description

technical field [0001] The invention relates to a heating device, in particular to a miniaturized instant heating device capable of pre-heating the water in the pipeline of the water supply device. Background technique [0002] At present, the bathroom and cleaning equipment used to achieve cleaning and washing functions usually have the function of supplying hot water and cold water. When users need to use hot water, they only need to open the hot water valve of the faucet to obtain hot water with sufficient temperature. water to use. [0003] General bathroom and cleaning equipment usually supply hot water through the heating effect of water heaters or gas stoves. However, since the water heater (gas stove) and the faucet are connected by a water pipe with a certain length, when using When the person wants to use hot water, although the water heater is turned on immediately to heat the cold water, because the water liquid remaining in the water delivery pipe is still cold...

Problems solved by technology

[0003] General bathroom and cleaning equipment usually supply hot water through the heating effect of water heaters or gas stoves. However, since the water heater (gas stove) and the faucet are connected by a water pipe with a certain length, when using When the person wants to use hot water, although the water heater is turned on immediately to heat the cold water, because the water liquid remaining in the water delivery pipe is still cold water, and it still takes a certain time for the water heater to heat up the cold water, so, In the habit of ordinary people, they usually let the cold water in the water pipe be drained through the faucet first, and after continuing to heat for a period of time, hot water with sufficient temperature can reach the faucet. Only then can the user start to use the hot water. This is obviously quite time-consuming and inconvenient

[0004] Moreover, in addition to the aforementioned water habits, if the weather is cold, the water heater will take longer to heat up, and more cold water will flow off. If the user does not have the habit of storing cold water, it will It will waste a lot of water, causing unnecessary waste of water resources, which is a pity

[0005] In addition, although there are many instantaneous electric water heaters on the market that claim to be able to provide hot water immediately, the principle is to quickly heat the running water through electronic heating elements to make the water temperature reach a temperature suitable for human body bathing, but in fact, this electric water heater The water heater still needs several seconds after the water comes out before the human body will feel that there is enough water temperature, which is also a waste of water. Moreover, its heating elements usually have to use higher power, which invisibly increases energy consumption. Moreover, it also lacks safety protection. mechanism and function, so there is still a need to improve
