Description

A New Storage Type Electric Water Heater

technical field

The utility model relates to a sanitary device, in particular to a novel water storage type electric water heater.

Background technique

At present, the function of ordinary water storage electric water heaters on the market is mainly aimed at the needs of users for bathing. If only a small amount of hot water is needed (such as washing the face and feet, etc.), the remaining hot water will be wasted, and the storage Water-type electric water heaters store water at a temperature of 60°C-80°C for a long time, which is prone to bacteria, which is not conducive to the health of users. At present, there are also many people who have produced various storage-type electric water heaters, which are generally modified on the heating device, and the selection of insulation materials has also improved. However, due to various reasons, it has not been widely produced and used.

The currently published patents mainly include:

1. The parent-child electric water heater invented by Gong Wei of Chongqing Zhide Thermal Industry Co., Ltd., patent number 01200494;

2. Haier Group Corporation; Sun Jingyan of Wuhan Haier Water Heater Co., Ltd.; Wang Renhua; Cai Xiangzhou; Sun Qiang; Zhao Xuesen invented the water storage electric water heater, patent number 200720306069;

3. The electric water heater invented by Huang Wensheng in Shibei District, Qingdao City, Shandong Province, patent number 200420096914;

4. The pre-heating constant temperature electric water heater invented by Feng Jun of Guangzhou Autlang Enterprise Co., Ltd., patent number 200420095156;

5. A new type of electric water heater invented by Ouyang Huaan in Maanshan, Shatin, Hong Kong Special Administrative Region, patent number 200320119550;

6. Wang Dawu from Nantou Town, Zhongshan City, Guangdong Province; Zheng Zhonghua invented the electric water heater, patent number 200320116956.

Contents of the invention

The utility model aims at the problem that the traditional water storage type electric water heater heats water, the waiting time is very long and the waste of remaining hot water is caused, and a new type of water storage type electric water heater is proposed. The shortcomings of electric water heaters can achieve better energy-saving effects.

The technical solution of the utility model is: a new type of water storage electric water heater, including two split water tanks, the large water tank is on the bottom, and the small water tank is on the top. The pipeline has only one water outlet pipe and one water inlet pipe. The two water tanks are respectively equipped with a heating tube and a temperature controller. The heating tube of the small water tank is directly connected to the power supply, and the heating tube of the large water tank is connected in parallel to the power supply through a parallel control switch.

The entire pipeline includes a hot and cold water mixing valve and a water pipe. The tap water enters the large water tank from the water inlet level, and is pressed out through the outlet pipe above the connected small water tank. The hot water from the outlet pipe is mixed with a part of the cold tap water entering the water inlet level. Through the hot and cold water mixing valve, it finally comes out from the water outlet level.

The beneficial effect of the utility model is that: the utility model is a novel water storage type electric water heater, which has the benefits of time saving, energy saving and environmental protection compared with the traditional water storage type electric water heater. Moreover, because the heat preservation time is saved, the possibility of bacterial growth is reduced, and it is more healthy and hygienic.

Description of drawings

Fig. 1 is a structural schematic diagram of a new storage type electric water heater of the present invention.

Detailed ways

As shown in the structural diagram in Figure 1, the new water storage electric water heater adopts a split water tank to store water, so that the electric water heater can be heated as required. are communicated through pipelines. A one-way valve 7 is arranged in the middle of the pipeline (to make water flow only from bottom to top). Two water tanks are equipped with a heating pipe 4,3 and a temperature controller 6,5 respectively. This scheme pipeline is simple, only has a water outlet pipe 12 and a water inlet pipe 13, and only the parallel control switch 11 is to be controlled, and this circuit is turned on if the whole water tank is heated, and this circuit is disconnected only if a small amount of hot water is needed. 9 is a hot and cold water mixing valve, 14 is a user water outlet, and 10 is a power plug. Tap water enters the large water tank 2 from the water inlet level 13, and is pressed out through the outlet pipe 12 above the connected small water tank. The hot water from the outlet pipe is mixed with a part of the cold tap water coming in at the water inlet level 13, and finally flows through the hot and cold water mixing valve 9. Water level 14 comes out.

The small water tank 1 and the large water tank 2 respectively store small-capacity and large-capacity water bodies, and the user selects the opening or closing of the parallel control switch 11 according to different situations. The temperature controllers 5 and 6 are respectively connected with the heating tubes 3 and 4 in the inner container. When the temperature reaches the set value of the user, the heating circuit is automatically disconnected, and when the temperature is lower than the set value, the heating circuit is automatically turned on. The circuit continues to heat up. The one-way valve 7 can ensure that the water in the two inner tanks does not carry out convective heat exchange under the situation of separately heating small-capacity water.

The selection of on or off of the parallel control switch can effectively achieve the purpose of using a large amount of hot water or using a small amount of hot water respectively. The temperature controller works normally, and can automatically cut off the heating circuit when the temperature reaches the predetermined set value to achieve heat preservation.
