Abstract

The utility model relates to a novel electric heating vessel, which comprises a vessel body, wherein the outer side surface of the vessel body is wound with electric heating wires in parallel, product slots are arranged between the electric heating wires, the two ends of the electric heating wires are respectively connected with metal sheets, the metal sheets are electrically connected with a power supply, the outer portions of the electric heating wires and the product slots are provided with outer covers, the inner sides of the outer covers are provided with heat insulation films, magnesia powder is filled in the product slots, and magnesia powder is filled between the outer walls of the electric heating wires and the vessel body and the electric heating wires and the outer covers. The novel electric heating vessel directly arranges the electric heating wires on the vessel body to heat the vessel, thereby reducing the loss of heat energy conduction of medium metal pipes, also increasing the contact area with the vessel, and increases the use rate of heat energy. The novel electric heating vessel avoids the trouble of scorching because of local heating and the risk of food safety, which is increased through directly heating in liquid. The applied range of the novel electric heating vessel is wider, and the cost is greatly reduced.

Description

A kind of novel electrical heating vessel

(1) technical field

The utility model belongs to the electric-heating technology field, especially relates to a kind of electric-heating container.

(2) background technology

In the prior art as soy bean milk making machine, hot-water bottle, coffee pot, electric cooker, electric pressure cookers etc. carry out mode of heating to container generally two kinds, a kind of mode is the bottom heating, be that calandria is arranged on container bottom, by the bottom heating means container is heated, thereby the liquid in the container is heated, it as the patent No. 200720054995.5 Chinese utility model patent thermal-insulation electric heating kettle, it comprises the kettle body, be installed on the independent power supply base of kettle body bottom, bottom in the kettle body is provided with heat-generating disc, one side is provided with heater in the bottom surface of this heat-generating disc, and opposite side is provided with thermostat in the bottom surface of heat-generating disc.Because of being provided with heater in the bottom surface of heat-generating disc, this heater if with the kettle body when independently the power supply base coupling is switched on, just can continue distribute heat.This localized heating method, the inhomogeneous situation that occurs burning of being easy to because heated object is heated.Another kind of mode is that heating tube directly is set in container, be among heating tube is arranged on liquid liquid directly to be heated, as the patent No. is that 91205645.2 long-life electric kettle (device) is the electrically heated hot water apparatus of a kind of resistance-type, inner bottom part at heated water container has sealed attachment mechanism by putting a bottom, and be fixedly connected with water container, its upper vertical stand in the bottom and with the bottom be the board-like electric heating element of resistance electric heating of complete integral body, whole electric heating element all is immersed in the water of water container except that the bottom surface.Heating tube is set directly in the liquid can to destroy liquid former nutritious, a large amount of incrustation scales that can form after long-term the use have increased the risk of edible safety.

And the electrothermal tube that existing electric heating is adopted is that a heating wire is penetrated in the metal tube, pours into the magnesium powder again in metal tube, finalizes the design by external force again.It as the Chinese utility model patent patent No. a kind of liquid electric heater of 200820235488.6, comprise metal outer pipe, its middle part is provided with resistance wire, is filled with insulating heat-conduction material between described resistance wire and the described metal outer pipe, wherein, be with the high-temperature insulation cover on described metal outer pipe surface.Be the double protection electric heater that 200820160215.X relates to a kind of single-ended outlet also just like the Chinese utility model patent patent No..This double protection electric heater includes the metal shell of a tubulose, be mounted with resistance wire in the shell, the sealing of shell one end, two exits of resistance wire are all drawn from the blank area of the shell other end, described resistance wire periphery also is with the inner sleeve of layer of metal, be filled with the heat conductive insulating medium between the inwall of inner sleeve and the resistance wire as inner insulating layer, also be filled with the heat conductive insulating medium between the outer wall of inner sleeve and the outer casing inner wall as external insulation layer.Shortcoming such as electrothermal tube cost height, the heat energy utilization rate of Sheng Chaning be low like this.

(3) summary of the invention

In order to overcome deficiency of the prior art, the utility model provides a kind of heat energy utilization rate higher, energy-conservation and increase the electric-heating container of edible safety.

The technical scheme in the invention for solving the technical problem is:

A kind of novel electrical heating vessel, comprise vessel, the parallel heating wire that is wound with on the described vessel lateral surface, be provided with the goods groove between the described heating wire, the two ends of heating wire are connected with sheet metal respectively, the sheet metal electric connection of power supply, and heating wire and goods groove are provided with outer cover outward, be filled with magnesia powder in the described goods groove, between heating wire and the vessel outer wall, all be filled with magnesia powder between heating wire and the outer cover.

Adopt canoe to make heating wire be wrapped in the vessel outside, increased the contact area of heating wire and container, solved the puzzlement that existing container causes burning etc. because of localized heating, also avoided electrothermal tube directly is placed in the liquid destruction to food, reduce the heat energy loss of the conduction of intervening metal pipe, significantly improved the heat energy utilization rate.When twining, can change canoe arbitrarily according to the container of Any shape, use more flexibly, greatly reduce cost.The magnesia powder conduct is distributed in around the heating wire for the heat conductive insulating layer.

As improvement, the outer cover inboard is provided with thermal isolation film.In outer cover built-in thermal isolation film, reduced the temperature of heater surfaces, be unlikely to outer cover because of the too high life-span that influences product of temperature, improved the security of products energy greatly.

As preferably, heating wire coiling or with the coiling of waveform mode threadably.Heating wire coiling is in different ways as required heated it at vessel.

Heating wire is connected by rivet with sheet metal.With the riveted joint mode heating wire and sheet metal are linked together, connect reliable.

The beneficial effects of the utility model are: the utility model directly heats heating wire to container on vessel, has reduced the heat energy loss of the conduction of intervening metal pipe, has also increased and the container contact area, has improved the heat energy utilization rate.And puzzlement of burning and the foodsafety risk that directly heating increases in liquid have been avoided because of localized heating.And the utility model range of application is more extensive, greatly reduces cost.
