Description

Improved small power electric energy water heater

The utility model relates to an improved low-power electric energy water heater.

Generally, the power of electric heaters of water storage type electric showers or electric water heaters needs to be at least 6000W to meet (meet) the needs of users - the heating time is short, and hot water of at least 40°C can be achieved without waiting for a long time temperature for shower use. Because household electricity in many areas of our country is only applicable to electric energy water heaters below 3000W, for high-power electric energy water heaters of 6000W or above, it can only be daunting, and there is no blessing to install and enjoy; However, when installing and using such a low-power storage-type electric shower or electric water heater, the heating time is very long, and it takes at least tens of minutes to reach The hot water temperature above at least 40 ℃ is used for showering and taking a bath, but it takes at least half an hour to take a bath every time, so people feel very time-consuming and inconvenient.

Aiming at the shortcomings of the prior art, the purpose of this utility model is to provide an improved low-power electric energy water heater to solve the problem of long heating time of the low-power electric energy water heater.

In order to achieve the above object, the utility model is achieved through the following technical solutions: an improved low-power electric energy water heater, which mainly consists of a small-power electric energy heater, a water storage tank, a water point electric switch device, a cold water inlet pipe, It consists of a water pump and a hot water outlet pipe; the water storage tank is a closed box made of nylon plastic material, an opening is provided at the bottom to install a water pump, and a buzzer device is installed on the upper side. A hot water inlet pipe is installed on one side of the box to connect with the low-power electric heater, and at the same time, an overflow pipe is installed on the other side of the upper side of the box; Between the water pipes, install a shunt pipe joint, a circulating hot water pipe, a water inlet solenoid valve and a three-way joint; install an electronic water level control switch at the water level above about 1 liter in the water storage tank and attach a An electronic control device that controls the opening of the water pump and water inlet valve.

The improved low-power electric energy water heater of the utility model overcomes the shortcomings of the prior art, makes the water temperature rise faster and saves heating time, and achieves the above-mentioned creation purpose.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Figure 1 is a schematic front view of the utility model.

As shown in Figure 1, the small power electric water heater improved by the utility model mainly consists of a small power electric heater 5, a water storage tank 15, a water point electric switch device 2, a cold water inlet pipe 1, a water pump 7 and a The hot water outlet pipe 14 is composed of; the water storage tank 15 is generally a sealed box made of nylon plastic material, an opening is arranged at the bottom to install the water pump 7, a buzzer device 8 is installed on the upper side, and the water tank 15 is set at the full water level. Can send warning sound when telling shower person can use; In the casing; at the same time, install an overflow pipe 9 on the other side of the upper side of the casing again, which can naturally overflow the overfilled water; The water level control switch 6 is also equipped with an electronic control device (not shown), so that when hot water enters the water level control switch 6 and reaches the position of the water level control switch 6, the water pump 7 and the water inlet valve 3 can be opened automatically, so that the water storage tank 15 Part of the hot water that has been heated in the interior is sent out and mixed with the cold water sent into the cold water inlet pipe 1 to become warm water, then it is sent to the low-power electric heater 5 for heating and then flows back into the casing of the water storage tank 15. The low-power electric heater 5 is a general low-power electric heater below 3000W. The hydraulic pressure of water is to open this low-power electric energy heater 5, makes it energized and does water heating action. On the pipeline of the hot water outlet pipe 14, an on-off valve 13 is installed to control whether the hot water is output for showering or not. In addition, between the cold water inlet pipe 1, the pump 7 and the hot water outlet pipe 14, the utility model is equipped with a shunt pipe joint 17, a circulating hot water pipe 11, a water inlet solenoid valve 3 and a tee Joint 16, and between this three-way joint 16 and small-power electric energy heater 5, install a warm water inlet pipe 4 to connect it in addition.

When the utility model takes a shower and takes a bath, it is the same as the operation and use of a traditional water storage type electric energy water heater. First, the opening and closing valve (not shown) on the cold water inlet pipe 1 must be opened, so that the cold water passes through the water point electric switch device 2 and then enters the existing water heater. Heated by the low-power electric energy heater 5 opened by the water point electric switch device 2, it enters the casing of the water storage tank 15 and stores it. The opening and closing valve 13 on the hot water outlet pipe 14 can be opened to make a shower and take a bath. The utility model does not "directly" heat and store cold water in the water storage tank 15, and then perform showering and bathing actions when 90% of the water level is full, but stores the water directly heated by the low-power electric heater 5 at the beginning of opening. In the water storage tank 15; when the water level reaches the position of the electronic water level switch 6, the water pump 7 and the water inlet valve 3 can be automatically opened, so that the heated part of the hot water in the water storage tank 15 can be pumped out by the water pump 7 , through the small shunt pipe 172 on the shunt pipe joint 17 of the shunt pipe 171, 172 (the size ratio is about 2.5 to 1 or 2 to 1), flows through the circulating hot water pipe 11, the water inlet solenoid valve 3 and the three-way joint 16, Then enter the warm water inlet pipe 4 and mix with the cold water newly entered by the cold water inlet pipe 1, after making the cold water become warm water, it flows into the low-power electric heater 5 for heating, and then enters the casing of the water storage tank 15 for storage; , except that the water heated at the beginning of the opening is cold water, the water that enters the low-power electric heater 5 and accepts heating is warm water; You can enjoy hot enough hot water for showering and bathing without waiting for a long time. When the hot water in the casing of the water storage tank 15 of the present utility model has reached about 90% of the full water level and is doing showering and bathing actions, although the opening and closing valve 13 on its hot water outlet pipe 14 has been opened, so that the flow of water from the shunt pipe The hot water in the storage tank 15 flows out from the large shunt pipe 171 on the joint 17, but a small part of the hot water still flows out through the small shunt pipe 172 on the shunt pipe joint 17 at the same time, and then flows into the warm water inlet pipe in the same manner as described above. In 4, it is mixed with the cold water newly entered by the cold water inlet pipe 1, which can also make the incoming cold water become warm water, circulate and reheat and then flow into the water storage tank 15, so it can shower and take a bath while supplementing hot water, and then do shower and take a bath People don't need to wait, they can continue to use it and get hotter and hotter. Compared with traditional low-power electric water heaters, it is really a world of difference.
