Description

Technical Field

[0001] This utility model relates to the field of electric water heater technology, and more specifically, to an electric water heater with a reboiling function. Background Technology

[0002] When using an electric water heater to heat water, this type of water heater mainly relies on an electric heating element to heat the water by converting electrical energy into heat energy. There are many types of electric water heaters on the market, some of which can control the temperature through a temperature sensor. When the corresponding temperature is reached, the heating element stops working, thus achieving temperature control.

[0003] Some electric water heaters, after boiling the water and stopping operation, will continue to control the heating element to heat the water back to a boil when the water temperature gradually decreases to the corresponding temperature, thus keeping the water at a boiling state.

[0004] However, in this type of electric water heater, the heating element and temperature sensor are fixedly installed inside the device, which is either non-removable or inconvenient to disassemble. This affects subsequent replacement or cleaning of the heating element, impacting ease of use and causing inconvenience to users. Therefore, we propose an electric water heater with a reboiling function. Utility Model Content

A support is inserted into the through hole, and an electric heating rod is fixedly installed at the bottom of the support. The electric heating rod is located inside the water tank. A temperature sensor is inserted into the insertion hole. A limit ring is fixedly installed on the top of the temperature sensor, and a fixing ring is fixedly installed on the top of the support. Both the limit ring and the fixing ring are detachably mounted on the top surface of the water tank. A control host is electrically connected to the electric heating rod and the temperature sensor. A conical cylinder is fixedly installed at the bottom of the water tank, and a drain pipe is fixedly installed at the bottom end of the conical cylinder.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Please see Figures 1-4 This utility model provides a technical solution: an electric water heater with reboiling function, including a water tank 1. A through hole 15 and an insertion hole 16 are provided on the top surface of the water tank 1. A support 20 is inserted into the through hole 15, and an electric heating rod 2 is fixedly installed at the bottom of the support 20. The electric heating rod 2 is located inside the water tank 1. A temperature sensor 24 is inserted into the insertion hole 16. A limit ring 241 is fixedly installed on the top of the temperature sensor 24, and a fixing ring 21 is fixedly installed on the top of the support 20. Both the limit ring 241 and the fixing ring 21 are detachable and installed on the top surface of the water tank 1. Specifically, the electric heating rod 2 is spiral-shaped to increase the heat exchange area; both the limit ring 241 and the fixing ring 21 are fixedly installed on the top surface of the water tank 1 by multiple fastening screws, facilitating installation and disassembly. Specifically, the electric heating rod 2 and the temperature sensor 24 are electrically connected to the control host 23. A conical cylinder 12 is fixedly installed at the bottom of the water tank 1.

[0017] In this embodiment, an inlet pipe 10 is fixedly installed on the top of the water tank 1, and an outlet pipe 11 is fixedly installed on the bottom of the water tank 1 to realize water inlet and outlet operations.

[0018] Specifically, the conical cylinder 12 is funnel-shaped, and the plane of the inner wall of the conical cylinder 12 is inclined downward at 30° to 60°, which facilitates impurities to fall down along the inner wall of the conical cylinder 12.

[0019] Furthermore, an insulating seat 22 is fixedly installed on the top of the support 20. The height of the insulating seat 22 is between 5cm and 8cm, and the insulating seat 22 is used for gripping operation.

At this time, the temperature sensor 24 continues to measure the water temperature. When the water temperature drops to the set minimum threshold, the control host 23 continues to control the electric heating rod 2 to heat the water to a re-boiling state. It should be noted that the control host 23, electric heating rod 2, and temperature sensor 24 of this utility model are all general standard parts or parts known to those skilled in the art.

After the water enters and is stored in the water tank 1, the device is connected to an external power source and put into operation. The control host 23 controls the electric heating rod 2 to heat the water, and the temperature sensor 24 detects the water temperature in real time. When the water is heated to boiling, the control host 23 controls the electric heating rod 2 to stop working. At this time, the temperature sensor 24 continues to measure the water temperature. When the water temperature drops to the set minimum threshold, the control host 23 continues to control the electric heating rod 2 to heat the water to the reboiling state. In addition, during cleaning, open the threaded cap 18 and add cleaning solution into the water tank 1. Afterwards, open the drain valve 131 to discharge impurities outwards through the drain pipe 13.
