Abstract
The invention discloses a dry heating preventing water dispenser heating cylinder which comprises a heating cylinder body, a water inlet pipe, a water outlet pipe, a blow-off pipe, an electric heater, a hot water temperature controller, a dry heating preventing temperature controller, a water level switch and a microswitch. The water inlet pipe and the water outlet pipe are arranged at the top of the heating cylinder body, the blow-off pipe is arranged at the bottom of the heating cylinder body, the electric heater, the hot water temperature controller, the dry heating preventing temperature controller and the microswitch are all arranged on the heating cylinder body, and the electric heater, the hot water temperature controller and the dry heating preventing temperature controller are all electrically connected with the microswitch. The water level switch is arranged at the bottom of the heating cylinder body and connected above the microswitch, and an inner ejector rod of the water level switch can vertically move relative to the microswitch along with changes of the water level of the heating cylinder to disconnect or connect an electric contact of the microswitch. In this way, a water level control mode is adopted to prevent dry heating, and the potential safety hazard that when dry heating happens, the dry heating preventing temperature controller of an outer heating type heating cylinder cannot fast power off a power source, and consequently, a heating cylinder heat preservation layer smokes and is on fire is eliminated thoroughly.
Description
Technical field
The present invention relates to field of water fountain, particularly relate to the hot cylinder of a kind of dry-combustion-proof drinking water machine.
Background technology
Along with people more and more pay attention to the water quality of drinking water, water dispenser enters huge numbers of families.Hot cylinder be in water dispenser most important one relate to safe and energy-conservation safe parts, play a part key at the energy-conservation and secure context of guarantee water dispenser.But regrettably, the hot cylinder of energy-saving external heating water drinking machine of all band sponge heat-insulating layers used on the market at present, its anti-dry burning safety device and insulation material all cannot accomplish this point.
After entering 2014, the U.S. has carried out enforceable new energy consumption standard to water dispenser product.In order to tackle new energy consumption standard, the method thickening hot cylinder sponge heat-insulating layer generally can only be taked to solve energy consumption problem.After sponge heat-insulating layer thickeies, the safety problem of water dispenser just more highlights.Once cause water dispenser hot cylinder heater energising when hot cylinder is not intake because of user's carelessness or water dispenser water route fault, the sponge heat-insulating layer of hot cylinder just can have been smoldered and even burnt before anti-dry burning safety device action.If electrified regulation under the state that hot cylinder does not enter full water, also can cause hot cylinder dry combustion method or produce a large amount of high-temperature steams, if now put hot water, the serious consequence that high-temperature steam is hurted sb.'s feelings will occur.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the hot cylinder of a kind of dry-combustion-proof drinking water machine, adopt water lev el control mode pre-anti-dry, the anti-dry heating temperature controller thoroughly solving external heating type heat cylinder can not cause hot cylinder heat-insulation layer to smolder potential safety hazard on fire by fast shut-off power supply when there is dry combustion method.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of dry-combustion-proof drinking water machine hot cylinder, comprise: hot cylinder body, water inlet pipe, outlet pipe, blow-off pipe, electric heater, hot water temperature controller, anti-dry heating temperature controller, water level switch and microswitch, described water inlet pipe and outlet pipe are arranged on the top of described hot cylinder body, described blow-off pipe is arranged on the bottom of described hot cylinder body, described electric heater, hot water temperature controller, anti-dry heating temperature controller and microswitch are installed on described hot cylinder body, and described electric heater, hot water temperature detect switch (TDS), anti-dry heating temperature controller is all electrically connected with described microswitch, described water level switch is arranged on the bottom of described hot cylinder body and is connected to the top of described microswitch, the interior push rod of described water level switch can move up and down relative to described microswitch, to disconnect or to connect the electric contact of described microswitch.
In a preferred embodiment of the present invention, described electric heater is the one of internal heat type electric heater or external-heat electric heater.
The invention has the beneficial effects as follows: the present invention is provided with the water level switch be connected with microswitch, this water level switch can move up and down according to the intrinsic water level height of hot cylinder; When in hot cylinder body during full water state, water level switch moves down, and promotes microswitch action, and microswitch is connected, electric heater electrified regulation; When hot cylinder body is in low water level state, water level switch moves up, microswitch disconnects, electric heater power-off stops heating, namely by the pre-anti-dry of water lev el control mode, thus the anti-dry heating temperature controller thoroughly solving external heating type heat cylinder can not cause hot cylinder heat-insulation layer to smolder potential safety hazard on fire by fast shut-off power supply when there is dry combustion method.
