Description

Technical Field

[0001] The utility model relates to the technical field of heating devices, and more specifically to an electric heater. Background Art

[0002] Existing electric heaters, such as the publication number CN114576687A, named an electric heating automatic circulating water heater, and the publication number CN2564919Y, named a water-filled self-circulating electric heater, are all manually filled with water through an open water tank. In order to facilitate the filling of water into the radiator, the water tank is generally installed higher than the radiator, which makes it more laborious to manually fill water. Moreover, after the electric heater is used for a period of time, the water in the water tank evaporates and the water level drops. In order to replenish water to the radiator in time, it is necessary to manually observe the water level of the water tank regularly. When the water level is insufficient, it is also necessary to manually replenish water, which is not only laborious, but also often causes insufficient heating of the radiator because people forget to replenish water. In addition, because there is no clothes drying rack on the existing radiator, people often put washed socks, jackets, pants and other clothes on the top surface of the radiator to facilitate the use of the radiator to achieve the purpose of rapid drying, but due to the limited area of ​​the top surface of the radiator, the number of clothes placed is limited.

[0003] Therefore, how to provide an electric heater that can automatically fill and replenish water to the radiator and has its own clothes drying rack to increase the number of clothes drying on the radiator is an urgent problem that needs to be solved by technical personnel in this field. Utility Model Content

[0004] In view of this, the utility model provides an electric heater which can automatically supply water to the radiator and replenish water and has its own clothes drying rack, thereby increasing the number of clothes drying on the radiator.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An electric heater, comprising:

[0007] A bottom plate, wherein a plurality of moving wheels are mounted on the bottom end of the bottom plate;

[0008] A radiator, wherein the radiator is fixed to the top of the bottom plate, and two sides of the radiator are respectively connected with a water inlet pipe and a water outlet pipe, wherein the water inlet pipe is located above the water outlet pipe, an exhaust valve is installed on the radiator, and a drain valve is installed at the end of the water outlet pipe;

[0009] A heating box, the top and bottom ends of which are respectively connected to and communicate with the water inlet pipe and the water outlet pipe, and a heating element is provided inside the heating box;

[0010] A water supply pipe, one end of which is connected to the water outlet pipe, and the other end of which is provided with a water supply bucket, and an upper water level sensor and a lower water level sensor are installed on the inner wall of the water supply bucket;

[0011] A water replenishing tank, the water replenishing tank is fixed on the top of the bottom plate;

[0012] A water pump, wherein the water pump is fixed on the top of the bottom plate, the water inlet of the water pump is connected to the water outlet of the water supply tank, the water outlet of the water pump is connected to a water pipe, and the end of the water pipe is located above the water supply bucket;

[0013] A controller is fixed on the top of the base plate and is electrically connected to the heating element, the upper water level sensor, the lower water level sensor, and the water pump.

[0014] Through the above technical scheme, it can be known that compared with the prior art, the utility model discloses an electric heater. When in use, the exhaust valve is opened, and the water pump is controlled by the controller to add water to the water supply bucket. The water enters the radiator and the heating box through the water supply pipe. When the water overflows from the exhaust valve, the exhaust valve is closed, and the water level in the water supply bucket is made to the position of the upper water level sensor. At this time, the controller controls the water pump to stop working, and then the controller controls the heating element to energize. The heating element heats the water inside the heating box. Due to the small density of hot water, it rises along the water inlet pipe and enters the upper part of the radiator. As the water temperature on the upper part of the radiator increases, the pressure gradually increases, and the cold water at the bottom of the radiator is pressed into the heating box through the water outlet pipe for heating. In this way, the water in the radiator is circulated and heated, and the temperature becomes higher and higher. As the temperature of the radiator becomes higher and higher, the temperature in the entire room is eventually increased, thereby achieving the purpose of heating. After the radiator has been used for a period of time, the water level in the water supply bucket drops to the position of the lower water level sensor. At this time, the controller controls the water pump to pump water from the water supply tank to the water supply bucket until the water level reaches the upper water level sensor and the water pump stops working. Therefore, the electric heater can automatically fill and replenish water to the radiator without manual filling and replenishing, saving time and effort, ensuring that there is enough circulating water inside the radiator to make the radiator work normally; and the electric heater can be moved at will according to the heating position.

[0015] Furthermore, it also includes a battery fixed on the top of the bottom plate, and the battery is electrically connected to the heating element, the upper water level sensor, the lower water level sensor, the water pump, and the controller.

[0016] The beneficial effect of adopting the above technical solution is that the battery supplies power to the heating element, the upper water level sensor, the lower water level sensor, the water pump, and the controller, so that the electric heater can work normally even when there is a power outage.

[0017] Furthermore: it also includes a power generation device, which is electrically connected to the battery.

[0018] The beneficial effect of adopting the above technical solution is: the power generation device is used to charge the storage battery, so that the electric heater can work even without electricity. In addition, the storage battery can also supply power to external electrical equipment.

[0019] Furthermore, the power generation device is a solar panel power generation device or a wind power generation device arranged on the roof, or a generator or a magnetic energy power generation device fixed on the top of the base plate.

[0020] Furthermore, an auxiliary lighting lamp is installed on the water supply pipe or the water supply bucket or the water delivery pipe, and the auxiliary lighting lamp is electrically connected to the battery and the controller.

[0021] The beneficial effect of adopting the above technical solution is that when there is a power outage, the battery can supply power to the auxiliary lighting lamp, thereby providing lighting during the power outage, which is very practical.

[0022] Furthermore, the heating element is an electric heating rod or an electromagnetic induction heating device.

[0023] Furthermore, it also includes an upper clothes hanging horizontal tube and a lower clothes hanging horizontal tube, one end of the upper clothes hanging horizontal tube is fixedly connected to the top of the front side of the radiator, and the other end is connected to and communicated with the water inlet pipe, one end of the lower clothes hanging horizontal tube is fixedly connected to the bottom of the front side of the radiator, and the other end is connected to and communicated with the water inlet pipe, and the upper clothes hanging horizontal tube and the lower clothes hanging horizontal tube are connected and communicated via a connecting pipe.

[0024] The beneficial effect of adopting the above technical solution is: the hot water in the water inlet pipe can enter the upper clothes hanging horizontal tube, and flow into the lower clothes hanging horizontal tube through the connecting pipe, and finally flow into the heating box through the water inlet pipe for heating circulation. Therefore, hot water is passed through the upper clothes hanging horizontal tube and the lower clothes hanging horizontal tube, so socks, tops, pants and other clothes can be directly hung on the upper clothes hanging horizontal tube and the lower clothes hanging horizontal tube for quick drying, and the upper clothes hanging horizontal tube and the lower clothes hanging horizontal tube can hang more clothes, avoiding the existing problem that clothes can only be stacked on the top of the radiator for drying, which causes the clothes to not be dried quickly and are easy to wrinkle.

[0025] Furthermore, it also includes a middle clothes hanging horizontal tube arranged between the upper clothes hanging horizontal tube and the lower clothes hanging horizontal tube, both ends of the middle clothes hanging horizontal tube are fixedly connected to the front side of the radiator, and the middle clothes hanging horizontal tube is connected and communicated with the connecting pipe.

[0026] The beneficial effect of adopting the above technical solution is that the amount of clothes hung out to dry can be further increased, thereby improving the practicality of clothes drying with electric heaters.

[0027] Furthermore, a support pad is fixed to a position of the water outlet pipe near its end, and the bottom end of the support pad is fixedly connected to the top end of the base plate.

[0028] The beneficial effect of adopting the above technical solution is that the support pad can support the end of the suspended water outlet pipe to prevent the end of the water outlet pipe from tilting and deforming. BRIEF DESCRIPTION OF THE DRAWINGS
