Description

A kind of overheat protective structure of electric hot water tap

Technical field

This utility model belongs to technical field of taps, particularly to a kind of electric hot water tap Overheat protective structure.

Background technology

Along with the raising of people's living standard, the use of tap water is popularized among the people already.But from The water outlet carrying out faucet is all cold water, wants to use hot water to be necessary for being equipped with electric heat water tank, electricity Water heater and electric heating faucet etc., wherein the use of electric hot water tap is the most convenient.Existing Some electric hot water tap technology are not mature enough, and cost is high, relates to complexity, and power consumption is big, and The most dry being heated to is damaged.In electric hot water tap, Thermal protection unit it is generally fitted with for this Part, thermal protective element and be generally arranged at the top that adds heat pipe, and when normally using, heat Protection element does not has cooling measure, causes the operating temperature point of the overtemperature protection that they design to compare Height, and use disposable fusing body heat to protect, use and maintenance is relatively costly.

Summary of the invention

The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that A kind of simple in construction, possesses the overheat protective structure of electric hot water tap of cooling effect.

The purpose of this utility model can be realized by following technical proposal: a kind of electric hot water The overheat protective structure of tap, it is characterised in that include

Water tank；

Adding heat pipe, helical disk is threaded onto in water tank；

Heating column, is located in water tank and is positioned on the spiral adding heat pipe bottom；

Hand-reset temperature detect switch (TDS), is installed on water tank, and hand-reset temperature detect switch (TDS) has Temperature-sensitive face and temperature-sensitive face are close to heating column lower surface；

Water inlet pipe, is inserted in water tank and the outlet of water inlet pipe is just to heating column.

In the overheat protective structure of above-mentioned electric hot water tap, open in hand-reset temperature control Shut and be provided with SR.

Compared with prior art, heating column is arranged on and adds heat pipe bottom by this utility model Spiral on, be close in the temperature-sensitive face of the lower surface of heating column with hand-reset temperature control, enter Water pipe enters the position of water tank and is arranged near heating column, and the outlet of water inlet pipe is just To heating column so that rush facing to heating column all the time from the cold water of water inlet pipe ejection, thus drop The temperature of low heating column, makes heating column temperature maintain the lowest temperature, thus avoids leading Plume temperature is excessive causes hand-reset temperature detect switch (TDS) to start the situation making dump, with Time also make the operating temperature of hand-reset temperature detect switch (TDS) arrange ratio relatively low；When improper During work (faucet stops water outlet, but machine is also in heating), owing to water does not flows, Heating column adds the temperature of heat pipes heat sympathetically, and temperature can rise rapidly, in the short time just The operating temperature point that hand-reset temperature detect switch (TDS) is arranged, hand-reset temperature detect switch (TDS) are reached Action, power supply is cut off, thus avoids the dangerous feelings such as water tank overheating deforming even catches fire The generation of condition.

Accompanying drawing explanation

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

In figure, 1, water tank；2, heat pipe is added；3, heating column；4, hand-reset temperature control Switch；5, water inlet pipe；6, SR.

Detailed description of the invention

The following is specific embodiment of the utility model and combine accompanying drawing, to this utility model Technical scheme be further described, but this utility model is not limited to these embodiments.

As it is shown in figure 1, the overheat protective structure of this electric hot water tap includes water tank 1, adds Heat pipe 2, heating column 3, hand-reset temperature detect switch (TDS) 4 and water inlet pipe 5, wherein add heat pipe 2 helical disks are threaded onto in water tank 1；In heating column 3 is located at water tank 1 and be positioned at and add heat pipe 2 On the spiral of bottom；Hand-reset temperature detect switch (TDS) 4 is installed on water tank 1, manually multiple Position temperature detect switch (TDS) 4 has temperature-sensitive face and temperature-sensitive face and is close to heating column 3 lower surface；Water inlet In pipe 5 is inserted in water tank 1 and the outlet of water inlet pipe 5 is just to heating column 3.

When needs faucet release hot water, add heat pipe 2 and produce heat and in water tank 1 Water heat, simultaneously because heating column 3 is positioned on the spiral adding heat pipe 2 bottom, Add heat produced by heat pipe 2 also can be transferred on heating column 3, and by water inlet pipe 5 The water entered in water tank 1 is cold water, and the outlet of water inlet pipe 5 is just to heating column 3, Therefore the cold water from water inlet pipe 5 ejection rushes facing to heating column 3 all the time, thus reduces heat conduction The temperature of post 3, makes heating column 3 temperature maintain the lowest temperature, thus avoids heat conduction Post 3 temperature is excessive causes hand-reset temperature detect switch (TDS) 4 to start the situation making dump, The ratio simultaneously also making the operating temperature of hand-reset temperature detect switch (TDS) 4 arrange is relatively low.

When non-normal working (faucet stops water outlet, but machine is also in heating), by Not flowing in water, heating column 3 adds the temperature of heat pipe 2 heating sympathetically, and temperature can be rapidly Rise, in the short time, just reached the operating temperature point that hand-reset temperature detect switch (TDS) 4 is arranged, Hand-reset temperature detect switch (TDS) 4 action, power supply is cut off, thus it is overheated to avoid water tank 1 Deform the generation of dangerous situations such as even catching fire.

Further, hand-reset temperature detect switch (TDS) 4 is provided with SR 6.When non- After normal work, only need to press this SR 6 can make hand-reset temperature detect switch (TDS) 4 reuse, and without replacing protection accessory of disassembling a machine, thus greatly reduce product Maintenance rate.

Specific embodiment described herein is only for example to this utility model spirit Explanation.This utility model person of ordinary skill in the field can be to described concrete Embodiment is made various amendment or supplements or use similar mode to substitute, but not Spirit of the present utility model can be deviateed or surmount model defined in appended claims Enclose.
