Abstract
The utility model discloses an electric heater, which belongs to the heating equipment, and mainly solves the problems of low speed and high energy consumption when the rice steaming cart is used for steaming rice. The electric heater comprises a shell and a cover which is arranged on the shell; the shell is provided with a water inlet hole; the cover is provided with a plurality of steam holes; the shell is provided with a grounding head and an electrode which is arranged through an insulation sleeve; the grounding head is connected with a cathode; an electrode is arranged in the shell; and the mounting end of the electrode is provided with a wiring head which is connected with a power anode. Because of a plurality of electrodes are adopted in the shell of the electric heater, the water in the shell can be rapidly heated to boil, thereby generating more steam and increasing the heating rate. Moreover, the utility model can greatly save the energy and prevent the dry burning.
Description
Technical field
The utility model relates to electric heating equipment, is a kind of electric heater, especially a kind of electric heater that is positioned in the tanks such as rice steaming car or food heating car.
Background technology
At present, the heating cars such as food that use in hotel, restaurant or the general dining room etc. all are to adopt following principle: adding the hot water with uniform temperature in the tank in its car carries out steam heat radiation or heat transfer, thereupon with on this tank or the container of splendid attire food wherein keep certain temperature.There is following drawback in such heating principle: 1, the hot water of the uniform temperature that adds in the tank, owing to be subjected to the influence of indoor or ambient temperature, cooling is very fast, is unfavorable for for a long time the food of institute's splendid attire is kept certain temperature, and this food cools off easily; 2, the hot water in the tank is owing to be subjected to the restriction of its temperature, and the steam that is distributed is less, and its heat time heating time is long, speed is slower.And for the rice steaming car that is exclusively used in steamed rice, if directly to the heating of the water in the tank, because water is more in the tank, the energy of consumption is big.
Summary of the invention
The utility model be solve existing food heating car firing rate slow, can not maintain in the certain temperature range for a long time and problem such as slow, the big energy-consuming of speed during rice steaming car steamed rice.Provide correspondingly that a kind of to distribute steam more, it is fast and can maintain in the certain temperature range to make it the food firing rate of institute's splendid attire when placing food heating car etc., and the electric heater low, anti-dry that consumes energy when placing rice steaming car to carry out steamed rice.
This electric heater is realized by following scheme: it has shell and is positioned on lid on the shell, has the inlet opening on shell, covers to have many steam vents; Described shell is provided with the ground connection head and is equipped with electrode by insulation sleeve; This ground connection head and negative pole join; This electrode places in the shell, and its mounting end has connector lug, is used for joining with positive source.
Above-mentioned electrode is more than two.
Above-mentioned shell is provided with the installation screw rod.
Electric heater of the present utility model is owing to adopt the polylith electrode to be arranged in the housing, can to enter in the housing the water Fast Heating or to boiling, thereby the steam that distributes is more, its firing rate is fast, and can save the energy widely, prevents dry combustion method.
Description of drawings
Fig. 1 is the schematic diagram of electric heater, has removed partly lid shown in the figure;
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, this electric heater has shell 1 and is positioned on lid 2 on the shell 1.This shell 1 is a container, and its shape can design as required, and shell shown in the figure 1 is a rectangular tank; On shell 1, has inlet opening 11; Shown in the figure, this inlet opening 11 is located on the bottom of shell 1, also can be located on the sidewall all around of shell 1, can be two or more; In use, the water of being convenient in heating cars such as food or the rice steaming car tank enters in the shell 1 by this inlet opening 11.Have many steam vents 21 on the above-mentioned lid 2, this steam vent 21 can be evenly distributed on and cover on 2.Lid 2 coincide with shell 1, in order to guarantee its globality, can lead to screw etc. between this lid 2 and the shell 1 and be installed together.Above-mentioned shell 1 is provided with ground connection 3 and is equipped with electrode 5 by insulation sleeve 4; This ground connection 4 is joined with negative pole; This electrode 5 places in the shell 1, is three, and is fixedly mounted in the shell 1 by felt pad 6, guarantees that it installs steadily, firmly, causes danger in case contact with shell 1; The mounting end of this electrode 5 has connector lug 51, is used for joining with positive source.
Above-mentioned shell 1 is provided with installs screw rod 7, can be fixedly mounted on by this screw rod 7 and supporting nut thereof on the sidewall of tank such as food car, easy to use.Screw rod shown in the figure is arranged at ground connection head or connector lug place.
Above-mentioned felt pad 6 and insulation sleeve 4 can be used rubber, pottery or plastic production.
Above-mentioned electrode 4 is tabular, is made by stainless steel material.
The utility model in use, by screw rod etc. it is installed on the tank sidewall of heating cars such as food and places tank, water in the tank will enter in the shell and water level is higher than electrode in the heater by the inlet opening, connect power supply, electrode (positive pole) is by forming the loop between water conduction and the ground connection head (negative pole), promptly to entering the water heating in the heater, because electrode heat production speed is fast, very fast intensification of water around it or extremely boiling, give out a large amount of steam, steam is overflowed by the steam vent that covers, thereby the container on it is incubated, heats.When the shell middle water level is lower than electrode in the heater, disconnect power supply, can prevent dry combustion method.
