Accompanying drawing explanation
Fig. 1 is the structural representation preventing the water dispenser repeatedly heated of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, it is the structural representation preventing the water dispenser repeatedly heated of the embodiment of the present invention.The water dispenser of the present embodiment comprises housing 1 and the hot-water cylinder 2 be arranged in housing 1, warm water tank 3 and cold water tank 4, warm water tank 3 is arranged on below hot-water cylinder 2, cold water tank 4 is arranged on below warm water tank 3, the top of hot-water cylinder 2 is provided with the first water control valve D1 connecting external water source, the bottom of hot-water cylinder 2 is communicated with warm water tank 3 by the second water control valve D2, the bottom of warm water tank 3 is communicated with cold water tank 4 by the 3rd water control valve D3, housing 1 be provided with respectively with hot-water cylinder 2, hot water effluent's pipeline 11 that warm water tank 3 is communicated with cold water tank 4, water outlet pipe road 12 and cold water outlet pipeline 13.In the present embodiment, the first water control valve D1, the second water control valve D2 and the 3rd water control valve D3 are check valve.
Be provided with in hot-water cylinder 2 for sensed water level the first level sensor 21, for detecting the first temperature sensor 22 and the heater 23 of water temperature, outside hot-water cylinder 2, be provided with PMU 24.When water level rises to the first height, the first water control valve D1 closes, and PMU 24 connects the power supply of heater 23, and heater 23 starts heating; When water temperature is higher than the first temperature, heater 23 stops heating, and PMU 24 cuts off the power supply of heater 23 and is only down to the second height at water level or again rises to the power supply just connecting heater 23 during the first height; When water temperature is lower than the second temperature, the second water control valve D2 opens; When water level is down to the second height, the first water control valve D1 opens, and the second water control valve D2 closes.
Be provided with in warm water tank 3 for the second level sensor 31 of sensed water level and the second temperature sensor 32 for detecting water temperature, when water temperature is lower than the 3rd temperature, the 3rd water control valve D3 opens; When water level is spent lower than third high, the 3rd water control valve D3 closes.
Wherein, when the water dispenser of the present embodiment uses at first, the top of water dispenser connects inverted dress bucket, water in dress bucket injects hot-water cylinder 2 from the first water control valve D1, when water level rises to the first height, first water control valve D1 closes, and PMU 24 connects the power supply of heater 23, and heater 23 starts heating when switching on power simultaneously.。After the water in hot-water cylinder 2 is boiled, water temperature is higher than the first temperature, heater 23 stops heating, and then PMU 24 cuts off the power supply of heater 23, and PMU 24 is only down to the second height at water level or is again risen to the power supply just again connecting heater 23 during the first height.It should be noted that the power supply connection of heater 23 does not represent heater 23 and starts heating, heater 23 needs to be subject to instruction when switching on power and just starts heating.Be down in the second temperature course in water temperature, the water in hot-water cylinder 2 can flow out from hot water effluent's pipeline 11, for drinking.Alternatively, water dispenser is when initial turn-on power supply, and the first water control valve D1 opens, and the second water control valve D2 and the 3rd water control valve D3 all closes.
If the hot water in hot-water cylinder 2 is not drunk for a long time, water temperature can slowly reduce, when water temperature is lower than the second temperature, hot water becomes warm water, and the second water control valve D2 opens, and the warm water in hot-water cylinder 2 enters warm water tank 3, water level decreasing simultaneously in hot-water cylinder 2, when water level is down to the second height, the first water control valve D1 opens, and the second water control valve D2 closes.Hot-water cylinder 2 injects the water of dress bucket again, and when water level rises to the first height, the first water control valve D1 closes, and heater 23 can continue to start heating.
After warm water in hot-water cylinder 2 enters warm water tank 3, warm water just stores in warm water tank 3.Water in warm water tank 3 can flow out from water outlet pipe road 12, for drinking.If the warm water in warm water tank 3 is not drunk for a long time, water temperature can slowly reduce, and when water temperature is lower than the 3rd temperature, warm water becomes cold water.At this moment the 3rd water control valve D3 opens, and the warm water in warm water tank 3 enters cold water tank 4.Water in cold water tank 4 can flow out from cold water outlet pipeline 13, for drinking.At this moment, after the hot water in hot-water cylinder 2 becomes warm water, be injected into again warm water tank 3.Thus water dispenser can provide hot water, warm water and boiled after cold water.If all fill water in hot-water cylinder 2, warm water tank 3 and cold water tank 4, even if when the hot water water temperature in hot-water cylinder 2 is lower than the second temperature, heater 23 also can not heat, because the first level sensor 21 does not detect that water level is down to the second height or again rises to the first height, thus can prevent hot water from repeatedly heating.
By the way, the water dispenser preventing repeatedly heating of the embodiment of the present invention by arranging hot-water cylinder in housing, warm water tank and cold water tank, if temperature reduces after the water heating in hot-water cylinder, warm water can enter warm water tank, if if the water temperature in warm water tank continues to reduce, cold water can enter warm water tank, simultaneously, warm water in hot-water line can continue to add to warm water tank, thus hot water can be provided simultaneously, the cold water of warm water and boiled mistake, heater in hot-water cylinder only heats by the control of level sensor, thus can prevent hot water from repeatedly heating, electric energy can be saved, the drinking water of various temperature is provided, the life be convenient for people to.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
