Description

Water heater with independent antifreeze heating function

technical field

The utility model relates to a water heater, in particular to a water heater with an independent antifreeze heating function for bathing.

Background technique

Water heater is a common bathing equipment. It uses various energy sources to heat cold water at a lower temperature to hot water at a suitable temperature for people to use. Common water heaters include gas water heaters, electric water heaters, etc. In practical applications, due to electric The water heater has the advantages of convenient connection, no consumption of gas to generate carbon dioxide, and easy installation, so it has been widely used in practical applications. In some relatively cold areas, due to the low temperature, the water in the water pipe will freeze due to the low temperature, which will cause the water pipe to be blocked, and even cause the frozen water to expand and cause damage to the water heater equipment. In order to prevent this When the situation occurs, many electric water heaters are equipped with antifreeze modules. These antifreeze modules are usually added with a temperature control heating module. The temperature control heating module includes a temperature detection controller and a heating control switch. The temperature detection controller is located on the electric heater. Inside, the heating control switch is connected to the heating device of the electric heater, and the temperature detection controller is connected to the heating control switch. When the temperature is lower than the preset temperature, the temperature detection controller controls the heating control switch to open, and the heating device starts Work and heat the water in the water heater, increase the water temperature in the water heater to prevent cold water from condensing, the antifreeze module of these common water heaters with antifreeze function is connected with the central function control module of the water heater behind the main switch of the water heater, therefore, When people turn off the power supply of the water heater for saving electricity, the water heater will no longer have the antifreeze function. If the antifreeze is to be continued, the total power supply of the water heater must be turned on all the time, which will not only affect the service life of the central function control module of the water heater, but also Power consumption is not conducive to environmental protection.

Utility model content

The technical purpose of the utility model is to solve the above-mentioned problems and provide a water heater with an independent antifreeze unit so as to provide an independent antifreeze function.

In order to achieve the above-mentioned purpose, the water heater with independent antifreeze heating function of the present invention includes a water heater body, a power input terminal, a central function control module, a water heater switch, a heating module and an antifreeze module. The water heater body includes a water heater inner tank for storing water, The water heater liner is set in the water heater body, and the heating module is set in the water heater liner. The power input end has two input electrodes, and the two input electrodes of the power input end are connected with the central function control module, the water heater switch, the heating module and the antifreeze module. The heating module of the water heater with an independent antifreeze heating unit is connected to the central function control module and connected in series with the water heater switch, and then the antifreeze module is connected in parallel to the two input electrodes of the power supply input end.

The above-mentioned antifreeze module includes a temperature detection controller and a heating control switch. The temperature detection controller includes a temperature control module and a temperature probe. The temperature probe is arranged in the inner tank of the water heater and connected to the temperature control module. The switch is connected, and the heating control switch is connected in series with the heating module and connected with the two input electrodes of the power supply input end.

Beneficial effects: the utility model has an independent antifreeze heating function water heater. Since the antifreeze module is directly connected to the external power supply at the front end of the main switch of the water heater, even if the water heater is turned off and used for the central function control module of the main control , it can also make the antifreeze module continue to work independently, so as to effectively prevent the temperature in the water heater from condensing due to too low temperature, and ensure that the water heater will not be damaged due to condensation. It can not only effectively prevent the water in the water heater from being frozen and condensed. Other control modules of the water heater, especially the central function control module, can be turned off during use, which not only saves energy and is more environmentally friendly, but also prolongs the service life of other control modules, especially the central function control module.

For the convenience of description and the detailed content and technology related to the utility model, it is described below with reference to the accompanying drawings.
