Description

Electric hot water tap

Technical field

The utility model relates to a kind of water tap, particularly a kind of electric hot water tap.

Background technique

The existing electric hot water tap that is contained on the water pipe, no matter whether inner bag is arranged, and inner bag which kind of material is made of, and in use all can run into a problem, at cold area, water in the dress water chamber can build-up ice, and the dress water chamber will be out of shape, and explodes under the serious situation, be out of shape under the slight situation, if things go on like this, product damages easily, and product safety performance and working life reduce greatly.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art part to provide a kind of and improve working life, and be used in may be freezing environment, improve product safety performance electric hot water tap.

The utility model is to constitute like this, it directly is contained on the water pipe, handle with sleeve can be realized hot water, Guan Shui, cold water, drain function, shell is made up of plastic part, the individual inner bag that independently makes up is arranged, heating tube, water switch, temp controller and thermal circuit beraker all are assemblied in the combination inner bag, combination inner bag water outlet is connected with outlet pipe, heating tube and water switch, temp controller and thermal circuit beraker are cascaded, it is characterized in that: cabinet body is a nylon products, loam cake is a copper spare, be respectively arranged with the cold water inlet channel on nylon inner bag and the structure that ceramic valve core cooperates, hot and cold water water outlet water channel, water is discharged water channel in energising pressure conduit and the courage, makes the handle valve have hot water, Guan Shui, cold water, drain function.

The utility model is owing to structurally increased and independently made up inner bag, and the combination cabinet body is a nylon spare, guaranteed water channel unimpeded and with the ceramic valve core fitting tight, cold water enters nylon inner bag handle cold water inlet channel from inlet channel.When handle is adjusted to the cold water shelves, the cold water that enters the hot water tap is by ceramic valve core cold water inlet channel and hot and cold water water outlet water channel, and cold water is through inner bag, and flows out from inner bag water outlet and hot water tap's outlet pipe; When handle is adjusted to the hot water shelves, then the energising pressure conduit by ceramic valve core imports the inner liner pressure hole with intake pressure, by water pressure pressure switch is connected, heating tube begins the energising heating, simultaneously the hot and cold water water outlet water channel of the ceramic valve core cold water that will enter the hot water tap imports inner bag, and the flow through heating tube of energising of cold water changes into hot water and flows out the hot water tap; When handle is adjusted to Guan Shuidang, then close the turnover water channel by ceramic valve core, simultaneously the water in the inner liner pressure hole is derived the energising pressure conduit to inner bag, thereby reach the venting water pressure, pressure switch is disconnected, heating pipe stops heating, thereby cuts the supply of water and electricity; When handle is adjusted to the draining shelves, water is discharged water channel water is guided to drain opening from inner bag in the ceramic valve core courage, thus with the water of inner bag the inside outside drain opening is discharged to electric hot water tap; Since there is not water storage in the inner bag, even therefore also can not be freezing at cold area, thus the working life of having guaranteed product.

In addition,, enough area of contact have been arranged, can arrange temp controller and thermal circuit beraker,, guaranteed the safety in utilization of product for electric hot water tap is provided with the protection of twice temperature control dry combustion prevention with hot water because the copper lid has been used on the top of combination inner bag.

Advantage of the present utility model is:

Because after finishing using, therefore electric hot water tap of the present utility model can avoid freezing phenomenon to take place inner water storage emptying owing to increased drain opening and realized drain function fully, has improved security of products energy and working life.In addition, also can regulate the height of water temperature according to the size of water flow.Temp controller and thermal circuit beraker can effectively guarantee the electrical safety of electric hot water tap.Power line can be dismantled, and can further realize aesthetic property.This product specification is reasonable, and is easy to use, and its market prospects are considerable.

Embodiment

Below in conjunction with drawings and Examples the utility model is specifically described.

With reference to accompanying drawing 1,2, electric hot water tap of the present utility model is directly to be contained on the water pipe by the interface 10 of will intaking, and its frame 16 is working of plasticss, and inner bag is fully independently.Cabinet body 17 is nylon spares, and the water channel control section is equipped with seal ring 14, ceramic valve core 15, handle 13, water pipe partly link to each other with cabinet body 17 inlet channels by bottom 11, when handle 13 places the cold water position, the cold water inner bag of flowing through, and flow out electric hot water taps from the outlet pipe 19 on inner bag top; When handle 13 places the hot water position, sensitive switch 8 is connected circuit, and heating tube 2 begins heating, and after cold water was flowed through the inner bag heating simultaneously, hot water flowed out electric hot water taps from the outlet pipe 19 on inner bag top; Put when handle 13 places the pass water level, cold water is closed on the intake pipe, does not have water to flow out, and the hydraulic pressure that will act on the sensitive switch 8 releases simultaneously, sensitive switch 8 resilience disconnecting circuits, and heating tube 2 quits work, and cuts the supply of water and electricity; When handle 13 places drainage position, originally the water on the cabinet body 17 is discharged from cabinet body 17, discharges from drain opening 12; Thereby guaranteeing does not have water in the cabinet body 17, can spalling under freezing situation, improved the safety coefficient of product, and prolonged working life.

Use for convenience, the control mechanism of described sensitive switch 8 is made up of diaphragm 3, push rod 4, spring 6, and the sensitivity of diaphragm 3 has realized that current one pass through, and push rod 4 drives spring 6 and moves downward, and withstands sensitive switch 8 and connects circuit.It can improve the convenience of use.

Water temperature is too high in order to prevent to use, and is serially connected with temp controller 1 in the circuit, in case water temperature reaches uniform temperature, temp controller 1 cuts off circuit rapidly, and protection the user of service do not scalded.

In order to prevent dry combustion method, be serially connected with thermal circuit beraker 18 in the circuit, in case when water switch short circuit and temp controller lost efficacy, thermal circuit beraker 18 can cut off circuit rapidly.

Aesthetic property in order to realize using, the power line 7 that is contained on the electric hot water tap can remove, and treats power line 7 to be entered from the water pipe below after electric hot water tap installs to install to again on the tenminal block 9 again.

In order to help reflecting the energising situation, be serially connected with tutorial light 5 on the circuit, tutorial light 5 is installed on the housing 16.

In use, when handle 13 rotates to the cold water shelves, cold water enters cabinet body 17 from intake pipe, and flows out from outlet pipe 19; When handle 13 rotates to the hot water shelves, cold water enters cabinet body 17 from intake pipe, and Jin Shui water flow pressure makes diaphragm 3 drive push rods 4 and spring 6 moves downward simultaneously, withstand sensitive switch 8, circuit is connected, and tutorial light 5 is bright, heating tube 2 begins heating, and hot water flows out from outlet pipe 19; When handle 13 rotated to Guan Shuidang, spring 6 rebounded diaphragm 3 and push rod 4, sensitive switch 8 disconnecting circuits; When handle 13 rotated to the draining shelves, the water that is stored in the cabinet body 17 flowed out from drain opening 12.
