Water saving water heater temperature control device

The present invention is to provide a water heater temperature control device, in particular, a hot water tap that immediately turns on hot water, so that the user can immediately use hot water, and there is no need to set a water-saving water heater temperature control device of the return water pipeline.

With the advancement of the times, water heaters have become an indispensable device for the current home life. The energy classification of water heaters can be divided into three types: gas water heaters, electric water heaters and solar water heaters. Among them, gas water heaters are most commonly used.

Conventional gas water heaters usually include a fan, a burner and a heat exchanger, and the burner can be used to heat the heat exchanger so that cold water can enter the heat exchanger for heat exchange and then drain the hot water.

However, when the water heater wants to use hot water, it takes a period of heating time to turn on the faucet before it starts to generate hot water, which not only wastes water resources, but also causes inconvenience to users. Especially in recent years, affected by environmental changes, the distribution of the rainy season is becoming more and more uneven, which leads to uneven water storage in the reservoir. Therefore, water shortage often occurs in the non-rainy season. If a large amount of water is wasted, the environment will also be expanded. Destruction, and wasting water, will also increase water bills, so saving water has become the mainstream in recent years.

The applicant has proposed a "water-saving circulation heating device" (certificate number: M433 543), which is mainly to set up a water return pipe in the water heater, which can heat the cold water in the pipeline through the pumping device to make the pipeline The cold water turns into hot water, and the faucet is turned on. That is, there is hot water, no longer cold water, to reduce the waste of water resources, and also allow users to immediately have hot water to use. However, the above-mentioned "water-saving circulation heating equipment" must be provided with a return water pipe to achieve the effect of water saving and immediate hot water use.

In summary, the creator feels that the above-mentioned deficiencies can be improved. He has devoted himself to research and cooperates with the application of academics, and finally proposes a design that is reasonable in design and effective in improving the above-mentioned deficiencies.

The technical problem to be solved by this creation is to provide a water-saving water heater temperature control device, and the water outlet device immediately has hot water, so that the user can immediately use hot water to reduce the waste of water resources without setting up a water return pipe. road.

In order to solve the above technical problem, the present invention provides a water-saving water heater temperature control device, comprising: a water heater unit connected with a cold water pipe and a hot water pipe; a pressurized pump connected to the water heater unit; a water outlet device, Connected to the hot water pipe; a remote controller, which is a remote controller having a preheating button, the remote controller is provided with a preheating heating time when the water heater is first installed; and a temperature detecting unit disposed at the The water detecting device is electrically connected to the water heater unit.

This creation has at least the following advantages: This creation can set the preheating heating time on the remote controller when the water heater is first installed. The preheating heating time is the time when the hot water can be heated. When the water heater is started, the pressure is pressed. The preheating button on the remote control causes the pressurized pump to pressurize the cold water, allowing the cold water to enter the water heater unit for preheating combustion. When the user turns on the hot water outlet device, the hot water is already heated, and the water is hot water. Allow users to have hot water immediately, which can reduce the waste of water resources, have the effect of environmental protection and energy saving, and do not need to set back water pipeline.

Furthermore, the present invention is provided with a temperature detecting unit that can use water as a medium or be electrically connected to the water heater unit in a wireless manner. When the hot water of the water outlet device disposed at the end reaches a certain temperature, the temperature detecting unit can pass water as a medium or The signal is sent wirelessly to the water heater unit, and the pressure pump is controlled to stop running, so that the temperature is no longer raised. In addition, the temperature detecting unit transmits the signal to the water heater unit through water as a medium or wirelessly, without wiring, so that the installation of the temperature detecting unit is simpler and easier.
