Description
Technical field:
The utility model relates to a kind of daily life electrical appliance, specifically is meant a kind of anti-dry electrothermal water boiling bucket.
Background technology:
Traditional electrothermal water boiling bucket can be temperature automatically controlled, lays in a large amount of boiling water, is widely used in meeting room, family, dormitory, dining room, hospital or the like, can satisfy the demand that people use boiling water.
But traditional boiled water pail discharging valve all is installed on the position from the high 10cm in bottom.During each the use, the bottom has a lot of boiling water to put to come out.It is in order to prevent that the heating element dry combustion method from damaging that its main cause of design of water is stayed in this bottom; but in fact still can not avoid dry combustion method; because the time has been grown under automatic temperature control device control, water can constantly be heated repeatedly and be evaporated, and still burns the disconnected protective device of heating element or thermosol at last.The anti-dry design of water is stayed in this bottom, all has a lot of boiling water to put to come out after each the use, has wasted electric energy.And the bottom stays water, forms incrusted deposit, influence health, and cleaning in each bucket all will be pulled out the attaching plug pouring, and is not only pretty troublesome, and high-power plug often stirs and just cause looseningly, causes the easy heating burnout of loose contact.
Summary of the invention:
Technical problem to be solved in the utility model is: when solving above-mentioned traditional electric heating boiling water bucket and using the bottom leave boiling water, waste electric energy, sediment incrustation, influence health, clean inconvenience, the reliable problem of anti-dry, and provide can conveniently drain Yu Shui after a kind of the use, avoid drinking water accumulate rotten, favourable people healthy, need not pull out attaching plug when cleaning, increase the service life and the outage of energy lack of water, anti-dry, safe and reliable anti-dry electrothermal water boiling bucket.
The technical solution adopted in the utility model is: this anti-dry electrothermal water boiling bucket, comprise staving, use water valve, heating element, level control switch for water and temperature adjustment gauge tap, feature of the present utility model is: in the bucket inwall bottom of staving or bucket open an aperture end and connecting pipe is installed adorns the level control switch for water water route with a bucket outer wall and be connected, or utilize water level displaying tube lower tube installation branched pipe to adorn the level control switch for water water route to be connected with a barrel outer wall; After connecting with temperature adjustment gauge tap circuit, level control switch for water directly or indirectly controls heating element.
In the technique scheme, after connecting with temperature adjustment gauge tap circuit, described level control switch for water directly or indirectly controls heating element, its physical circuit is: level control switch for water, temperature adjustment gauge tap, heating element three circuit series connection back are connected with power supply, perhaps level control switch for water, temperature adjustment gauge tap circuit series connection back connect control relay, relay contact is connected heating element and power supply thereof again, and perhaps level control switch for water and temperature adjustment gauge tap are controlled heat-generating pipe and relay respectively.
In the technique scheme, the bottom angled of staving or be tapering in the lowest part perforate of the bucket wall of staving, is installed and use water valve, in the bucket end lowest part perforate of staving, the cleaning draining valve is installed.
In the technique scheme, the bottom of staving also is equipped with in the electric power loop or power control loop that heat witch is connected on heating element.
The utility model in bucket inwall bottom or bucket open an aperture 3 end and communicate with level control switch for water 2 water routes that barrel outer wall is adorned, above-mentioned level control switch for water 2 is connected with temperature adjustment gauge tap 5, heat witch 8, circuit, directly or indirectly control heating element 4, when the inner bucket water position is higher than level control switch for water 2 setting values, level control switch for water 2 closures, the temperature regulating switch in the series circuit just can normally be controlled the work of heating element.When water level in the boiled water pail is lower than the setting value of level control switch for water 2; level control switch for water 2 disconnects; series circuit between level control switch for water 2 and the temperature adjustment gauge tap 5 just disconnects; therefore formed reliable lack of water outage anti-dry holding circuit; owing to adopt water level control anti-dry protective device; just can be installed on a barrel wall lowest part with water valve, make the bottom be detained boiling water less as best one can, thus more energy-conservation than traditional boiled water pail.Because bottom angled or be tapering is installed draining valves in lowest part perforate 7, so just can thoroughly drain waste water when cleaning, not pull out attaching plug again, remove a barrel pouring, cleaning has conveniently prolonged attaching plug service life.

The specific embodiment:
This anti-dry electrothermal water boiling bucket, comprise staving 1, use water hole 6, heating element 4, level control switch for water 2 and temperature adjustment gauge tap 5, feature of the present utility model is: in the bucket inwall bottom of staving or bucket open an aperture 3 end and connecting pipes are installed are connected with bucket level control switch for water that outer wall is adorned 2 water routes, or utilize water level displaying tube lower tube installation branched pipe to be connected with barrel level control switch for water that outer wall is adorned 2 water routes; After connecting with temperature adjustment gauge tap 5 circuit, level control switch for water 2 directly or indirectly controls heating element 4.
In the technique scheme, control heating element after described level control switch for water is connected with temperature adjustment gauge tap circuit, its physical circuit is: level control switch for water 2, temperature adjustment gauge tap 5, heating element 4, heat witch circuit series connection back are connected with power supply, perhaps level control switch for water 2, temperature adjustment gauge tap 5, heat witch circuit series connection back connect control relay 9, and relay contact is connected heating element 4 and power supply thereof again.The bottom angled of staving or be tapering in the lowest part perforate of the bucket wall of staving, is installed and use water valve, in the bucket end lowest part perforate of staving, the cleaning draining valve is installed.The bottom of staving also is equipped with in the electric power loop or power control loop that heat witch is connected on heating element.
Operation principle:
Referring to Fig. 1～3, connection power supply, temperature adjustment gauge tap 5 is forwarded to the boiling water gear, the temperature adjustment gauge tap closing of contact, as if lack of water this moment, level control switch for water 2 contacts disconnect, and relay 9, heating element 4 all can not be worked.In bucket, add water, when water level surpasses the water level settings line, level control switch for water 2 closings of contact, conducting heat witch and temperature adjustment gauge tap 5 and relay 9 electric currents, relay 9 often open the group contact closure, heating element 4 begins to heat.When inner bucket water seethed with excitement, temperature adjustment gauge tap 5 contacts disconnected, and stopped heating.Open and use water valve, boiling water is through flowing out up to using up with water hole 6, when water level is lower than the water level settings line, level control switch for water 2 contacts disconnect, and cut off the series circuit in the temperature adjustment gauge tap 5, at this moment, no matter temperature adjustment gauge tap 5 is closed, still disconnect, relay 9 and heating element 4 all can't be worked, and have avoided the dry combustion method damage effectively.When needing to clean, in the water washing bucket, then, open draining valve, waste water is 7 outflows through the hole.
