Abstract

The utility model relates to a temperature adjustable and automatic temperature control electric heating water kettle, and is a daily life appliance, comprising a water kettle, an electric heating pipe, an electric socket, a protective cover, a ground strip and a temperature control switch. The utility model is characterized in that the temperature control switch is provided with a temperature regulating turn knob. The utility model optionally selects the required heating temperature and automatically controls the temperature in the definite temperature range. The utility model can boil boiling water, and can warm the beverages with no high-temperature boiling requirements, such as yellow wine, fruit juices, milk, etc. The utility model enhances the convenience, scientific sanitation and safety of the electric heating water kettle in use. The utility model has the advantages of simple structure, and convenient manufacture, use and maintenance.

Description

Temperature adjustable and automatic temperature control electric heating water kettle

The utility model belongs to a kind of life appliance, is the improvement to existing electric kettle.

The technical scheme of the relevant electric kettle that commercially available electric kettle and Chinese patent application propose, in fact all be a kind of kettle of the usefulness that boils water, its temperature control and warning device are and boil water this purpose and be provided with, and increased the complexity of structure: what have is double-decker, and what have then will be at the inner installing of kettle thermostat.Yet the demand in the people life is diversified, moreover for example yellow rice wine, fruit juice, milk are also unsuitable or unnecessary high temperature is hotted plate for some feed, and obvious, existing electric kettle just is difficult to satisfy this instructions for use.

But the utility model purpose provides a kind of temperature adjustment temperature self-controlled electric kettle, and this kettle can be selected temperature required arbitrarily in certain temperature range and carry out temperature automatically controlled.

The utility model comprises kettle, electrothermal tube, electrical socket, guard shield, ground strip and temperature detect switch (TDS), it is characterized in that temperature detect switch (TDS) is equipped with thermoregulation knob.Kettle is made with copper or aluminum.

But can temperature control temperature adjustment again, the utility model has from warm feed to the multiple use that boils water, and this has not only improved convenience, science health and security on electric kettle uses, and has in fact also played the effect of saves energy.

Now structure of the present utility model is described with following embodiment.

Fig. 1 is the schematic diagram of the utility model assembling.

Fig. 2 is temperature adjustment, temperature regulating device schematic diagram.

As shown in Figure 1, but temperature adjustment temperature self-controlled electric kettle comprises kettle 7, electrothermal tube 1, electrical socket 3, guard shield 6, ground strip and temperature detect switch (TDS).Kettle is made with copper or aluminium, and warning device also is housed on the pot lid of kettle.Electrothermal tube 1 is loaded on bottom in the kettle, and its mounting screw passes the outer bottom that kettle body and function nut is fixed in kettle through sealing gasket 2.The two ends of electrothermal tube are connected in series with the contact of indicator lamp 5 backs in parallel and temperature detect switch (TDS).As shown in Figure 2, temperature detect switch (TDS) is made up of conducting strip 8, bimetal leaf 9, stationary contact 17, movable contact 16 and reed 15 thereof, thermoregulation knob 4, porcelain packing ring 10, porcelain rod 13,14, flat board 11 and screw, nut, conducting strip 8 is close to kettle kettle body and function nut and is fixed on the mounting screw of electrothermal tube 1, and and bimetal leaf 9 keep excellent contact, the free end of bimetal leaf is by the end in contact of porcelain rod 14 with reed 15.Thermoregulation knob 4 usefulness screw threads are installed on dull and stereotyped 11, rotate the preset value of thermoregulation knob 4 by the advance and retreat change reed 15 of porcelain rod 13, just can select required heating-up temperature arbitrarily in 40 ℃～100 ℃ temperature range, at this moment, and dynamic and static contact butt.So, after the electrothermal tube of kettle is connected with the mains, indicator lamp 5 is bright, when the temperature of liquid in the kettle reaches selected heating-up temperature, the free end of bimetal leaf 9 is heated to upwarp by porcelain rod 14 pushing tows and makes reed 15 bounce-backs, so movable contact 16 tripping from the stationary contact 17, the electrothermal tube outage, indicator lamp 5 extinguishes.After electrothermal tube quits work, when liquid cools in the kettle below selected temperature, when bimetal leaf 9 also was returned to certain position gradually with cooling, reed promptly started resilience, made dynamic and static contact butt again, electrothermal tube begins again to heat.So repeatedly, thereby reach temperature automatically controlled purpose,, also unlikelyly dryout water liquid very soon or lead to fire as for the moment unattended.If in order to boil water, when water was boiled, circuit was cut off in the temperature detect switch (TDS) action, and warning device also sends acoustic signal immediately simultaneously.12 is spacer pin.
