Abstract

The utility model relates to an electric heating water heater with a safety device, comprising a magnetic anti-dry burning device, a temperature control safety device, etc. The electric heating water heater with a safety device is characterized in that the magnetic anti-dry burning device is arranged in a water storage tank, and the magnetic anti-dry burning device is composed of a magnetic float, a reed pipe, and an executive element. The temperature control safety device is composed of a lever type valve, a bracket, and a temperature control spring. The middle part of a lever is arranged on the support point of the bracket through a hinge. The bracket is arranged along the inner wall of an inner liner, the upper end of the bracket is fixed on a water tap, and the lower end of the bracket is connected with the temperature control spring. The electric heating water heater with a safety device can be automatically powered off under the state of no water. When water temperature is lowered, a water discharge valve is automatically closed, thereby, electricity use safety is ensured; meanwhile, the safety of drinking water is also ensured.

Description

The electric water boiler of band safety device

The utility model relates to electric water boiler, particularly a kind of electric water boiler with safety device.

Common electric water boiler all is to adopt float-ball type valve control water inlet, when the user connects when using boiling water from boiled water tank, ball float in the storage tank is just followed the decline of water level and Open valve, cold water is continued to flow into water tank, and flow directly in the boiled water tank, the cold water boiling water is mixed by water inlet pipe.Because this class boiler is not with water temperature control device, therefore the inaccessible effective scalding of boiling water of being emitted does not meet hygienic requirements, hinders the healthy of people.In addition, common electric water boiler is not with the anti-dry system, will cause dry combustion method when people do not note adding water, causes component wear, and serious also can causing caught fire etc. not enough.

The purpose of this utility model is to overcome above-mentioned deficiency and a kind of band anti-dry and temperature control safety device is provided, and can guarantee anhydrous automatic outage, the descend electric water boiler of self-closing valve of water temperature.

Technical solution of the present utility model is: a cover magnetic dry burning resistance switch is set in the storage tank of this boiler, and this switch is made of jointly magnetic float, tongue tube and execution relay.One cover temperature control erecting device is set simultaneously, by lever valve, temperature control spring be configured on inner bag.The middle part of lever is arranged on by hinge on the supporting-point of support, and support is along inner bag inwall upper and lower settings, and its upper end is fixed on the tap, and the lower end connects the temperature control spring, and the other end of this spring is connected with the lower end of valve.Thereby when the water temperature in the inner bag burnt more than 95 °, the contraction distortion of temperature control spring drove lever simultaneously and opens draining valve automatically.

The utility model has the advantages that: have simple in structurely, reasonable in design, safe in utilization, under no aqueous condition, heat-generating pipe does not heat, and adds water with the musical sound prompting, guarantees Electrical Safety.Simultaneously, this boiler also is provided with advanced memorial alloy body spring and controls safety valve, thereby guarantees just can open water discharging valve when water temperature reaches more than 95 °, guarantees the drinking water safety health of outflow, meets national standard.

Below in conjunction with accompanying drawing the utility model is illustrated.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an electrical schematic diagram of the present utility model.

Shown in Figure 2 as Fig. 1: this boiler comprises that storage tank 1, blast pipe 2, magnetic float 3, inspection water power device box 4, valve 5, tap 6, support 7, temperature control spring 8, switch 9, heat-generating pipe 10, water inlet pipe 11, temperature detector 12, inner bag 13, tongue tube 14, relay 15 constitute jointly.Said magnetic float 3 is arranged in the storage tank 1, tongue tube 14 is fixed in the upper end that standpipe leaves the water surface, when cistern water level is lower than the boundary water level of setting, magnetic float is floated downward and is made the tongue tube can not adhesive, the inspection water circuit makes the relay saltus step by signal, disconnect the heat-generating pipe power supply, send the musical sound prompting simultaneously and add water, reach the purpose of anti-dry.

For guaranteeing the safe drinking water health, the utility model has adopted memory alloy spring to control safety valve, be arranged in the inner bag 13 by support 7, the other end of this spring 8 connects the lower end of lever valve 5, and the middle part of valve 5 is arranged on the strong point of support 7 by hinge.Above-mentioned support 7 is along the setting of inner bag inwall, and the upper end is fixed in tap 6 upper and lower ends and is connected spring 8.When the water temperature of inner bag burnt more than 95 °, the 8 beginning contraction distortions of temperature control spring drove lever simultaneously and open valve, and just have boiling water to flow out if tap is opened this moment.Because the utility model is to adopt sealing water-head gravity flow to discharge water, promptly emit how many boiling water, just advance how many unboiled water, therefore when water temperature in the inner bag is reduced to below 85 °, temperature control spring 8 can open automatically because of the decline of water temperature, drives lever simultaneously with valve closing, the also anhydrous outflow of tap even if fetch boiling water this moment, have only when water temperature reaches standard valve and just can be performed fighting again, thereby guarantee the safe drinking water health.

Claims

1, a kind of electric water boiler with safety device, comprise storage tank (1) magnetic anti-dry burning device, inspection water power apparatus (4), the temperature control safety device, heating element heater (10), inner bag formations such as (13), it is characterized in that: said magnetic anti-dry burning device is arranged in the storage tank (1), it is by magnetic float (3), tongue tube (4) and execution relay (15) are common to be constituted, said temperature control safety device is by lever valve (5), temperature control spring (8), support (7) constitutes, the middle part of lever is arranged on the supporting-point of support (7) by hinge, support (7) is along inner bag inwall upper and lower settings, its upper end is fixed on the tap (6), the lower end connects temperature control spring (8), and the other end of spring (8) connects valve (5).

2, electric water boiler according to claim 1, it is characterized in that: said temperature control spring (8) is a memorial alloy body spring, be arranged on the place of close heating element heater, when the inner bag water temperature rose to more than 95 °, this temperature control spring contraction distortion drove lever simultaneously and opens valve (5) automatically.
