CN2391138Y - Atmospheric thermal-storing electric heating hot water device - Google Patents

Abstract

The utility model discloses an atmospheric thermal-storing electric heating hot water device, particularly a household electric heating hot water device. The utility model is composed of a box body, an electric heating pipe, an electromagnetic valve, a water level controller, a temperature controller, a flow power-off switch and an electric control system. A water inlet hole, a water outlet hole and gas guide hole are arranged on the box body. The outside of the box body is provided with an insulating layer and a cover casing. In use, after the electric heating pipe heats a water to reach a predetermined temperature, the temperature controller switches off an electric source of the electric heating pipe by the electric control system and the box body insulates the water from an outside for a long time. When the water is outputted, the flow power-off switch switches off the electric source of the electric heating pipe by the electric control system to ensure safety. The utility model is suitable for heating the water at night to be used in daytime, which relieves the conflict of shortage electricity used by an electric network at night.

Description

A kind of constant pressure storing heating formula electrical heating water heater

The utility model relates to a kind of electrical heating of constant pressure storing heating formula water heater, particularly family expenses electrical heating water heater.

Development along with electric utility, the contradiction of electrical network electricity consumption at night deficiency is comparatively outstanding, how a kind of contradiction that can alleviate electrical network electricity consumption at night deficiency is provided, and the electrical heating water heater that can bring convenience to people life again is for, electricity consumption department questions of common interest.The conventional electric heating water heater, generally have two types: a class is the form that the limit heating edge is confessed hot water, for guaranteeing to confess the temperature of water, all adopts powerful electric heating tube, but often be subjected to the restriction of family's power supply capacity, so it is comparatively outstanding with the contradiction of electric load to confess heat; Another kind of form for the heating of volume water storage after the container inner storing water is heated to uniform temperature, is confessed hot water again, there is cold water constantly to add in the container therebetween, the electrical heating water heater of this class form, the power of electric heating tube can be relatively littler, but fluctuating temperature is bigger.Above-mentioned electrical heating water heater all belongs to and promptly heats the i.e. form of usefulness, though can bring convenience to people's life, generally all uses when peak of power consumption, so can not alleviate the contradiction of electrical network electricity consumption at night deficiency.In addition, also exist and to satisfy people's moment big flow and take the demand of hot water.

The purpose of this utility model provides a kind of constant pressure storing heating formula electrical heating water heater, and it both can alleviate the contradiction of electrical network electricity consumption at night deficiency, can satisfy people's moment big flow again and take the demand of hot water, and confess the water temperature ripple disable, and electric heating tube power is little.

For achieving the above object, the utility model comprises casing, electric heating tube, electric control system, electric heating tube is positioned at casing, the one end is fixed on the outer face of casing, on casing, have the inlet opening, apopore, apopore connects effluent switch by pipe, it is characterized in that: also comprise magnetic valve, water level controller and temperature controller, the input of magnetic valve connects the water source, the inlet opening of output termination casing, water level controller one end places in the casing, the other end is fixed on the outer face of casing, and the probe skewer of temperature controller is gone in the casing, and heat-insulation layer and outer cover are housed outside casing, have gas port at the casing top, electric control system connects magnetic valve respectively, water level controller and temperature controller.

The flow cut-off switch also is housed between above-mentioned apopore and the effluent switch, and the flow cut-off switch connects electric control system.When water was exported, the flow cut-off switch promptly sent the signal of cutting off the electricity supply, and electric control system is cut off the power supply of electric heating tube immediately.

The utility model is owing to adopt said structure, make the interior water of casing after electric heater for heating, can do long-time insulation, realized the purpose of night storage heating heat supply on daytime, both can alleviate the contradiction of electrical network electricity consumption at night deficiency, can satisfy people's moment big flow again and take hot water, and it is little to confess fluctuating temperature, electric heating tube power also can reduce.In addition, the water level in the casing can be selected according to user's request; Once water supply, cut off the electricity supply immediately in the use, safer reliable.
