Abstract
The utility model discloses a boiling type liquid electric heater, which includes a casing, a multi-channel water inlet connector and a liquid and gas separation device. A glass electric heating tube is arranged in the casing and includes a glass tube and an electric heating film coating the outside of the glass tube; the glass tube extends upwards to form a first extended glass section communicated with the liquid and gas separation device, and extends downwards to form a second extended glass section communicated with the multi-channel water inlet connector; and a leakage protection device is arranged on the multi-channel water inlet connector. The utility model has the advantage of eliminating a multi-channel water outlet connector on the present heater, a leakage protection device on the multi-channel water outlet connector, and a silicone tube for connection, thereby simplifying the whole structure of the heater, lowering the production cost, and avoiding water leakage caused by deformation of the silicone tube in conditions of accelerated aging and no-water heating after being heated for a long term. Compared with the silicone tube, the glass tube has low possibility of causing scale deposit, thereby ensuring the water quality of drinking water.

Background technology
The boiling type liquid electric heater is installed in the existing water dispenser; China Patent No. is that 200820136143.5 utility model discloses a kind of boiling type liquid electric heating assembly; its structure comprises housing; be provided with a plurality of vitreous electricity heat pipes in the housing; the lower end of housing is provided with multichannel water inlet connector; be connected between the water inlet of the delivery port of multichannel water inlet connector by first silicone tube and vitreous electricity heat pipe; multichannel water inlet connector is provided with into water earth leakage protective device; the upper end of housing is provided with multichannel and goes out water connector; the delivery port of vitreous electricity heat pipe is connected by the water inlet that second silicone tube and multichannel go out water connector; the delivery port that multichannel goes out water connector is connected with the water inlet of liquid-gas separation device, and multichannel goes out water connector and is provided with the water outlet earth leakage protective device.There are the following problems for the electric heater of this structure: 1, the vitreous electricity heat pipe is in feedwater heating process, its temperature can reach the 180-200 degree, owing to be the boiling type heating, water after the heating upwards flows, second silicone tube that is positioned at glass heats pipe upper end can be because be heated and accelerated ageing for a long time, aging back second silicone tube and vitreous electricity heat pipe junction can produce the slit, and the water in the vitreous electricity heat pipe will leak out from the slit, and the Electric radiant Heating Film outer with glass tube contacts the generation that causes leaky.2, under vitreous electricity heat pipe dry-fire condition, the temperature of glass tube can sharply raise, and results in its directly second silicone tube distortion of contact, and infiltration can cause leaky.3, experiment shows in water temperature and reaches 60 degree when above, the easy scaling of silicone tube, therefore be positioned at vitreous electricity heat pipe delivery port one end second silicone tube accumulate more incrustation scale, influence the water quality of drinking water.
Summary of the invention
Technical problem to be solved in the utility model provides better, the simpler boiling type liquid electric heater of structure of a kind of security.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of boiling type liquid electric heater; comprise housing; multichannel water inlet connector and liquid-gas separation device; be provided with the vitreous electricity heat pipe in the described housing; described vitreous electricity heat pipe comprises glass tube and is wrapped in the outer Electric radiant Heating Film of glass tube; glass tube extends upward and forms the first prolongation glass segments; described glass tube extends to form second downwards and prolongs glass segments; described first prolongs glass segments is communicated with described liquid-gas separation device; described second prolongs glass segments is communicated with described multichannel water inlet connector by silicone tube, and described multichannel water inlet connector is provided with earth leakage protective device.
Described second prolongs glass segments is communicated with described multichannel water inlet connector by silicone tube.The water temperature of water inlet end is lower, can be at silicone tube place scaliness.
Described liquid-gas separation device is provided with a plurality of water inlet pipes, and first prolongs the glass segments upper end is communicated with water inlet pipe, and described first prolongation glass segments and water inlet pipe are outside equipped with adapter sleeve.Adapter sleeve plays first effect that prolongs glass segments and water inlet pipe that connects.
The protective sleeve of heatproof is equipped with in the contact position of vitreous electricity heat pipe and housing.Protective sleeve prevents that housing from directly contacting with glass tube, avoids the breakage of glass tube.
Earth leakage protective device comprises metal connecting piece and ground strip; described metal connecting piece is installed on the multichannel water inlet connector; described metal connecting piece stretches in the intake tunnel of described multichannel water inlet connector; described ground strip is fixed on the described housing, and described metal connecting piece is connected with described ground strip by lead.When the silicone tube between the multichannel water inlet connector and the second prolongation glass segments wears out because of long-term use, the leaky of leaking and causing, metal connecting piece can be transferred to the electronics in the water in the ground strip, guarantees user's safety.
Housing is provided with overtemperature protection system, and the input of described overtemperature protection system is connected with power supply, and the output of described overtemperature protection system is electrically connected with Electric radiant Heating Film.After the vitreous electricity heat pipe was overheated, overtemperature protection system can be stopped power supply dump.
Liquid-gas separation device comprises cavity, blast pipe and outlet pipe, described water inlet pipe is arranged on the downside of cavity, described water inlet pipe place is provided with the aqueduct of the water backflow that prevents in the cavity, described aqueduct lower end has been wholely set back-up ring, described aqueduct passes described water inlet pipe and extend in the cavity, described back-up ring leans against the lower end of water inlet pipe, and described blast pipe is communicated with described cavity, and described outlet pipe is arranged on the downside of cavity.The water that heated in the cavity can not reenter in the glass heats pipe by aqueduct, avoids heating once more the energy dissipation that causes and to the influence of water quality.Liquid-gas separation device produces hot gas and discharges by blast pipe, and the water after the heating is discharged by outlet pipe.
Compared with prior art; advantage of the present utility model is that the first prolongation glass segments directly is connected with liquid-gas separation device; saved that multichannel on the existing heater goes out water connector, multichannel goes out earth leakage protective device and the silicone tube that is connected usefulness on the water connector; make the overall structure of heater simpler, reduced production cost.Because having saved existing heater goes out the silicone tube that water connector is connected with multichannel, avoid silicone tube because of leaking that accelerated ageing or the dry combustion method distortion of being heated for a long time causes.Glass tube is not easy to cause the incrustation scale phenomenon with respect to silicone tube, has guaranteed drinking water quality.
