Abstract
The utility model relates to the water-heater field which aims to provide a self-heating freezing-resistant electric water heater. The anti-freezing structure comprises a temperature controller and an electric heating device connected in a controllable manner, the electric heating device is disposed on a water-passing member on the water heater. The concept of the structure is that the electric heater can be started to heat the water-passing member when the temperature drops to such a degree that the accumulated water can be frozen.
Description
Technical field
The utility model relates to field of water heaters, a kind of water heater that can prevent that the water heater internal duct from freezing of saying so more specifically.
Technical background
Water heater generally keeps a part of ponding in portion's overcurrent member within it after use, the antifreezing measures that existing domestic gas instantaneous water heater is taked are to be provided with jettison gear, require the user manually to discharge water and reach antifreeze purpose, but the user can often forget in the reality, like this in particularly bursting by freezing in winter in the north in winter because water heater the inside ponding is icing, cause the out of use thing of water heater to take place often, so user's an urgent demand improve to this kind situation.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of water heater of heating and anti-freezing automatically is provided.
The utility model is achieved through the following technical solutions its purpose.
The utility model provides a kind of electrical heating antifreezing water heater, and its anti-freezing structure mainly comprises temperature controller and electric heater, and temperature controller connects with electric heater control, and electric heater is located at crossing on the water member of water heater.The inventive concept that this structure is is to drop under the situation that the ponding that is enough to make in the water heater freezes in temperature, starts electrical heating the water member of crossing in the water heater is heated, and prevents that it from freezing.Whether electric heater starts by temperature controller is controlled, when dispatching from the factory, water heater sets a critical-temperature to temperature controller, when the temperature that records when temperature controller is lower than this temperature, just starts electric heater and heat, critical-temperature is generally selected between 0～5 ℃.The control that stops to heat can be determined by time or two parameters of temperature.The mode of time is to set the lasting heating of electric heater one end to stop heating after the time, and this time period was generally 5～20 minutes, was enough to the ponding temperature increase to being higher than 2～10 ℃ of critical-temperatures.The temperature controlling mode is to set second critical-temperature in temperature controller, and second critical-temperature generally is higher than 2～10 ℃ of critical-temperatures, and when the temperature that records when temperature controller was higher than second critical-temperature, electric heater just stopped heating.
In order to be under the situation that is about to freeze at water heater, heat the ponding in it rapidly, prevent that water heater is freezing.The utility model generally is located at electric heater comparatively concentrated the crossing on the water member, as the heat exchanger or the water guide pipeline of water heater of ponding.And can further be provided with a plurality of electric heaters and be located at respectively on heat exchanger and the water guide pipeline, or an electric heater that power is bigger is set in main ponding position.Setting can promote the temperature of ponding fast like this, prevents that it from freezing.
Because the space in the water heater is limited, for simplified structure, save the space, the utility model generally adopts flat ceramic heater as electric heater.Ceramic heater can be adjacent to and be heated member, and contact area is big, heats effective.
In order to save electricity consumption, the convective principles that the utility model makes full use of the hydro-thermal conduction heats the ponding in the water heater, and soon electric heater is nested with the pipe bent position at heat exchanger tube, helps the convection current conduction of heat like this.
In order accurately to detect the temperature of water heater, it is minimum or near the minimum position of temperature generally temperature controller to be located in the water heater temperature.On the heat exchanger of being located at water heater or water guide pipeline, heat exchanger, water inlet pipe and outlet pipe are the water member excessively of water heater, also are the positions of easy ponding, when heat exchanger is located at above-mentioned position, can detect the temperature of ponding in the water heater accurately, prevent that it from freezing.Also can be located on the smoke exhaust pipe or petticoat pipe of water heater stating temperature controller.Because smoke exhaust pipe directly is in communication with the outside, so the temperature of above-mentioned member is the minimum position of temperature in the water heater basically, temperature controller is located at this position can accurately prevents ponding to freeze.
The utility model also provides a kind of control electrical heating antifreezing water heater more flexibly, its anti-freezing structure mainly comprises temperature controller, electric heater and controller, controller connects with temperature controller and electric heater control respectively, and electric heater is located at crossing on the water member of water heater.Whether this structure is to control electric heater by controller according to the signal of temperature controller to enable.The control mode of controller can also further provide more diversified control mode except the control mode that first kind of structure can be provided.Can also set described critical-temperature according to concrete operating position by controller such as the user, or select whether enable antifreeze function or the like, use humanized.
The utility model has following substantive distinguishing features and progress with respect to prior art.
1. good freezing protection effect, the duration is of a specified duration;
2. carry out antifreezely automatically, need not manual intervention, easy to use;
3. simple in structure, on original water heater basis, carry out simple modifications, need not production line is carried out a large amount of modifications, save production cost;
4. control flexibly can be according to concrete environment setting, and is humanized.
