Description

Intelligent constant temperature water saving device for water heater

technical field

The purpose of the utility model is to provide an intelligent constant temperature water-saving device for water heaters for household water heaters, especially relates to intelligent water-saving sensors, and belongs to the field of green economy and environmental protection. the

Background technique

A hot issue of global concern today is the development of the green economy. The United Nations Environment Program recommends that a large amount of funds be invested in new green industries for the development of a green economy. It can also change the major environmental problems facing our planet, such as water shortages and air pollution. . The United Nations Environment Program advocates requiring countries to invest at least one-third of their investment in a green economy. In China, not only environmental protection, but also the development of green economy is more important. the

China's water heater market is showing a high-speed growth trend, but it is difficult to use a single product to meet the comprehensive needs of consumers in safety, convenience, comfort and energy saving. Xu Dongsheng, secretary-general of China Household Electrical Appliances Association, believes that energy conservation and emission reduction is the development direction advocated by the state at present, and products with less energy consumption will be a direction of future development. the

At present, there are various types of water heaters on the market. Some use the law of water temperature stratification that hot water rises and cold water sinks to realize stratified heating of water and set the outlet pipe to extend to the top of the inner tank to discharge the hot water from the upper layer first. wait. Although hot water can be excluded, there are certain disadvantages. One, the temperature of the water is not uniform enough, which makes it uncomfortable to use, and also causes a slight cold for the weak, causing unnecessary troubles. Second, a certain amount of water will remain in the outlet pipe after each use, and the hot water will cool down soon. A water heater without an intelligent water-saving device will not automatically recover this part of cold water, and it is generally not used directly when the nozzle is turned on next time. But the cold water that stays in the water outlet pipe must be released earlier, and it will be used formally when the water temperature is suitable, causing a large amount of waste of water resources during this period. the

Utility model content

The main purpose of the utility model is to solve the above-mentioned shortcomings in the prior art, and further provide an intelligent constant temperature water-saving device for water heaters. the

In order to solve the above technical problems, the technical solution of the utility model for the intelligent constant temperature water-saving device for water heaters is: comprising a control panel, a shell, an insulation layer, an inner tank, a hot water pipe, a cold water pipe, a constant temperature warm water outlet pipe and The spray head is provided with a mixed water circulating pump between the shell and the inner tank, and the water inlet pipe and the outlet pipe of the mixed water circulating pump are connected with the inner tank, and the inner tank is provided with a liquid level sensor, a temperature sensor and a Low-power heating rod; a solenoid valve is respectively provided on the hot water pipe and the cold water pipe, and on the pipe section between the outer shell and the inner tank; the constant temperature warm water outlet pipe is provided with a The booster pump also includes a return pipe, one end of the return pipe is connected to the constant temperature warm water outlet pipe, the other end of the return pipe is connected to the inner tank, and the constant temperature warm water outlet pipe and the return pipe A three-way solenoid valve is provided at the interchange. the

The utility model is used for an intelligent constant temperature water-saving device for a water heater, wherein the temperature sensor is located at the lower part of the inner tank. The mixed water circulating pump is arranged on the outer wall of the inner tank. The water inlet pipe and the water outlet pipe of the mixed water circulating pump lead in from the bottom of the inner tank. The height of the water inlet pipe of the mixed water circulating pump leading into the inner tank is 1/2 of the height of the inner tank, and the distance between the water inlet pipe and the outlet pipe of the mixed water circulating pump is 1/2 of the length of the inner tank. The booster pump adopts a pressure-adjustable booster pump. the

Compared with the prior art, the beneficial effects of the utility model are:

(1) When the water level reaches the set temperature, the three-way solenoid valve located at one end of the constant temperature water outlet pipe is opened, and warm water flows out of the nozzle. When not in use, the water in the inner tank can be kept warm through the insulation layer, and when the temperature is lower than the set temperature, the low-power heating rod starts to heat up, so that the water in the inner tank is always kept at the set temperature. Thus, the utility model can ensure uniform water temperature and comfortable use. the

(2) Since the mixed water circulating pump is provided between the housing and the inner tank in the utility model, and the mixed water circulating pump is always in working condition during the water injection process, the water flowing out of the outlet pipe always maintains the set temperature. Therefore, when in use, warm water that meets the temperature requirements can be discharged at any time through the nozzle, avoiding the defect in the prior art that a large amount of water resources are wasted due to the need to drain the cold water stored in the outlet pipe first. the

The intelligent water-saving device for the water heater of the utility model meets the requirements of the future development direction, and is environmentally friendly and practical. the
