When the usage of the hot water is finished, water cannot be injected to the water storage groove by the water outlet pipe of the water storage cavity, the water in the water storage groove is completely guided into the water discharge groove to be discharged by an inversed U-shaped pipe, thus, the water storage groove is in empty state, and enough space is provided for accommodating the water flowing from the water outlet pipe during heating the water in the water storage cavity.
Description
Affiliated technical field
The utility model relates to a kind of water heater with open-type cistern, the water heater of the open-type cistern outwards not dripping while especially having heating.
Background technology
At present, widely used storage-type electric water heater, is comprised of water tank, heating or heat exchange element, waterpipe and water valve.It uses heating or heat exchange element the water in water tank to be carried out to the heating of long period, the storage-type electric water heater re-using after the temperature that makes it to reach certain.The water storage cavity that the water tank of this water heater is surrounded by housing, upper hose, outlet pipe form.The water tank of storage-type electric water heater is wrapped in heat-insulation layer conventionally, is therefore also referred to as " inner bag ".
The water tank of storage-type electric water heater is divided into two kinds of closed and open types.Enclosed water tank adopts the water valve of installing on outlet pipe to control, and when closing outlet pipe water valve, water storage cavity seals, so sealing type cistern need to bear the pressure of supply water of water system, that is to say that it is a pressure vessel.The water tank of open type adopts the water valve of installing on water inlet pipe to control, the water in water storage cavity directly and atmosphere communicate, water tank does not bear the hydraulic pressure of water system.Just because of this, the water heater difficulty of processing with sealing type cistern is large, expensive, and fault during use is more; And the water heater structure with open-type cistern is simple, handling ease, cheap, use procedure is safe and reliable.But the water heater with open-type cistern has a shortcoming, be exactly when the water of heating in water storage cavity, due to water be heated after volumetric expansion, part water can or flow out from outlet pipe drippage.
Summary of the invention
In order to overcome the shortcoming of outwards dripping when the existing water heater with open-type cistern heats, the utility model provides a kind of water heater with novel open-type cistern, this water heater has kept the existing water heater with open-type cistern, and does not have water from water heater drippage or flow out can guarantee the water heating in feed-tank time.
The utility model solves the technical scheme that its technical problem adopts: the effluent pipe mouth of water heater open-type cistern arrange outward a uncovered hopper accept water storage cavity in the water that overflows of expanded by heating.Be arranged side by side a bottom with the uncovered rhone of drainpipe (top that so-called " uncovered " refers to groove directly and atmosphere connection) with hopper, and make the bottom of rhone lower than the bottom of hopper.Partition wall with an inverted ∪ shape pipe through hopper and rhone is communicated with two grooves, the volume that should guarantee hopper ∪ shape pipe wall-through hole bottom can hold all water that outlet pipe overflows when the water in water storage cavity heats, and the mouth of pipe that should guarantee ∪ shape pipe in hopper approaches the bottom of groove, should guarantee that the mouth of pipe of ∪ shape pipe in rhone is lower than the mouth of pipe in hopper simultaneously.During hot water in using water heater, open water injection valve and to water storage cavity, inject cold water with water injection pipe, hot water in water storage cavity enters hopper by outlet pipe overflow, the effect of being now inverted ∪ shape pipe is, when the liquid level in hopper exceeds the peak of being inverted ∪ shape pipe, make to be inverted ∪ shape pipe siphonage occurs, the water in hopper is imported to rhone and through drainpipe, discharge.When the process of hot water finishes in using water tank, close the water injection valve of water heater, the outlet pipe of water storage cavity is no longer toward water filling in hopper, and the effect of being now inverted ∪ shape pipe is that the water in hopper is all led to sky.For fear of because the internal diameter of ∪ shape pipe is too large, while making inverted ∪ shape pipe that siphonage occur, the speed of flowing water is too fast, cause water in hopper to be led going on that sky makes that siphonage can not be continuous, the internal diameter of ∪ pipe should be controlled between 3～10mm, be conventionally chosen as 5～6mm.When large in order to ensure water consumption, the water in hopper can be imported rhone smoothly, and the part that hopper and rhone partition wall should be managed to position through walls higher than ∪ shape is got through, and makes it to form a crest of weir being inverted on ∪ shape pipe extreme higher position.The temperature of discharging water for adjusting drainpipe, can arrange one with the cold water pipe of cold valves at rhone place, to inject cold water to reduce the temperature of discharging water in the hot water of rhone.In order to reduce thermal losses, can be incubated water storage cavity.When only water storage cavity being incubated, hopper and rhone can be arranged on outside heat-insulation layer.When water heater integral body is incubated, can will on hopper and rhone, adds one with the upper cover of blast pipe, and exhaust pipe mouth is stretched out outside heat-insulation layer.
The operation principle of the water heater of the open-type cistern outwards not dripping while having heating is: when the water in storing water in water tank chamber heats, the water expanded by heating in water storage cavity, makes part water overflow to hopper and store from outlet pipe.When opening the water supply valve of water tank and use the hot water in water tank, the water of water system flows into water storage cavity from water inlet pipe, cause hot water flow into hopper and rapidly the volume below hopper two groove partition wall crests of weir filled with from the outlet pipe of water storage cavity, also make the highest point of inverted ∪ shape pipe be full of water.Because hopper and rhone are all uncovered, when being full of water, the highest point of inverted ∪ shape pipe just in inverted ∪ shape pipe, there is siphonage, the water in hopper is imported to rhone.When the water from outlet pipe inflow hopper is discharged into the water of rhone more than inverted ∪ shape pipe from hopper, the partition wall crest of weir that the water in a part of hopper is crossed two grooves flows into rhone.Water in rhone is derived by drainpipe, for people to use.If the temperature of drainpipe outflow water is too high, can open the cold valves at rhone place, make the cold water in cold water pipe flow directly into the water mixing that in rhone and groove, temperature is high, to reduce the temperature of discharging water.When using the process of hot water to finish, close (the rhone place cold valves of unlatching also should be closed) after the water intaking valve of water inlet pipe, the outlet pipe place of water tank will there will be no water to flow into hopper, the process that water in hopper flows into rhone through overflow crest of weir so will stop, but because hopper and rhone are all uncovered, and the siphonage of being inverted in the middle of two grooves in ∪ shape pipe has occurred, so in hopper, whole water all imports rhone discharge by the ∪ shape pipe being squeezed.Now hopper is just again in anhydrous state, while having again enough spaces to hold the water in heating water storage cavity from the water of outlet pipe overflow.
The beneficial effects of the utility model are, can overcome the water heater shortcoming that water heater outwards drips when the water in water tank heats with open-type cistern, and simple in structure, and handling ease is cheap, use reliable.
