Problems solved by technology

However, due to the large volume of gas water heaters or gas wall-hung boilers, there may be a large temperature difference between the installation position of the antifreeze heating resistor and the installation position of the thermostat. When the thermostat is closed, the entire antifreeze heating resistor is in a heating state, right? For places that need to be heated, the work of the antifreeze heating resistance has caused a large waste of energy

Embodiment 1

[0033] Such as figure 1 As shown, a water heater antifreeze heating device is introduced in this embodiment. The antifreeze heating device is arranged in the water heater 4, and can heat the inside of the water heater 4 when the internal temperature of the water heater drops to a certain value, so as to prevent freezing in winter, especially in the north. In winter, the water in the water heater freezes and cracks, causing the water heater to be unusable.

[0034] In this embodiment, the water heater antifreeze heating device includes a power supply module and a plurality of heating bodies. A plurality of heating bodies 2 are connected in parallel to each other and then electrically connected to the power supply module 1 . Since the heating bodies 2 are connected in parallel, each heating body 2 can work independently without affecting each other. A temperature controller 3 is connected in series on the branch road where each heating body 2 is located, and each temperature co...

Embodiment 2

[0044] Such as figure 1 As shown, in this embodiment, when any one of the thermostats 3 detects that the temperature of the area corresponding to the heating body 2 is abnormal, the thermostat 3 can control the water heater 4 to issue an alarm, prompting the user that the temperature of the corresponding area is abnormal. By enabling the thermostat to control the water heater to issue an alarm after detecting that the temperature in the area where the corresponding heating body is located is abnormal, the user can be promptly prompted that the corresponding area is abnormal, and the thermostat can control the water heater to stop issuing the alarm after the temperature in the area is normal. The user can know the working status of the heating body in time, and find out the abnormality of the heating body in time. At the same time, it can accurately confirm the location of the abnormal heating body, which is convenient for the maintenance personnel to repair it.

Embodiment 3

[0050] Such as figure 1 As shown, a water heater 4 is introduced in this embodiment, and the water heater 4 is equipped with a water heater antifreeze heating device as described in any one of the first and second embodiments above. The water heater antifreeze heating device includes a power supply module and a plurality of heating bodies. A plurality of heating bodies 2 are connected in parallel to each other and then electrically connected to the power supply module 1 . Since the heating bodies 2 are connected in parallel, each heating body 2 can work independently without affecting each other. A temperature controller 3 is connected in series on the branch road where each heating body 2 is located, and each temperature controller 3 can detect the temperature of the area where the corresponding heating body 2 is located, so as to control the connection or disconnection of the corresponding branch circuit, so that the corresponding heating body 2 starts or stop working.

Abstract

The invention discloses an anti-freezing heating device of a water heater. The device comprises a power supply module, and multiple heating bodies electrically connected with the power supply module after connection in parallel; branch ways of all the heating bodies are serially connected with temperature controllers; and the temperature controllers detect the temperatures of areas of the corresponding heating bodies to control communication or disconnection of the corresponding branch ways so as to start or stop the work of the corresponding heating bodies. The invention further discloses thewater heater; and the anti-freezing heating device of the water heater is mounted in the water heater. Each heating body is serially connected with one single temperature controller; the temperaturecontrollers can control working states of the corresponding heating bodies according to the temperatures of the areas of the corresponding heating bodies; and the anti-freezing heating device can heatthe internal of the water heater only in heating needed areas, achieves precise heating, and reduces the energy waste.

Description

technical field [0001] The invention belongs to the technical field of water heaters, and in particular relates to a water heater antifreeze heating device, and also relates to a water heater equipped with the antifreeze heating device. Background technique [0002] At present, most of the gas water heaters or gas wall-hung boilers use antifreeze heating devices to prevent the products from being damaged by freezing due to low temperature. The antifreeze heating devices are mainly based on cement antifreeze heating resistance, supplemented by a single thermostat to control the heating body. When the thermostat in the whole machine detects that antifreeze heating is required, the thermostat will control the antifreeze heating resistance to energize and heat. However, due to the large volume of gas water heaters or gas wall-hung boilers, there may be a large temperature difference between the installation position of the antifreeze heating resistor and the installation positio...
