Abstract
The invention relates to an electric water heater with three electric heating tubes, which is a totally-closed electric storage water heater comprising a known shell, an insulating layer, a pressure-bearing liner, a temperature switch and two electric heating tubes. The first electric heating tube is a bottom electric heating tube arranged on the bottom of the water heater; the second electric heating tube is a top electric heating tube arranged adjacent to the top water outlet; the top electric heating tube heats water at the top water outlet partially so as to meet the requirement for users to use hot water in a large amount; the third electric heating tube is a middle electric heating tube arranged in the middle part; and the temperature switch is arranged adjacent to the hot water outlet above the top electric heating tube. The invention is suitable for manufacturing a new generation of electric water heaters.
Description
Technical field
The present invention relates to a kind of household electrical appliance, especially totally-enclosed water-storage electric heater.
Background technology
At present, the totally-enclosed water-storage electric heater of known family expenses mainly is made of shell, heat-insulation layer, pressure-bearing inner bag, electric heating tube, and its operation principle is to heat the water that is stored in the pressure-bearing inner bag by electric heater.
But, near the general only installing electric heating tube water heater bottom of prior art scheme, this just causes that the user uses when having a bath in fact mainly is the hot water that just is stored in before having a bath in the water heater liner, after the beginning of having a bath, because the convection current of hot and cold water, in fact the bottom electrical heating tube will heat the water in the whole inner bag, so the temperature rise of unit power is slow, washes finally often water heater outlet having become warm water.If electric heating tube is arranged in the top, the convection current of hot and cold water only limits to top area, and the temperature rise of unit power is just than comparatively fast, so electric heating tube is arranged in the top feedwater heating after the beginning that is fit to have a bath.
In order to overcome near the only installing electric heating tube water heater bottom of prior art scheme, cause the user after beginning to have a bath, the slow deficiency of temperature rise of bottom electrical heating tube unit power, the invention provides the electric heater that a kind of pair of electric heating tube is arranged in top and bottom, it has the advantage of top electric heater and bottom electrical heater concurrently, improves hot water output and energy-saving effect in addition.
The technical solution adopted for the present invention to solve the technical problems is: the present invention utilizes the essential structure of a totally-enclosed water-storage electric heater, comprises known shell, heat-insulation layer, pressure-bearing inner bag, temperature switch, two electric heating tubes.First electric heating tube is the bottom electrical heating tube that is arranged in the water heater bottom, second electric heating tube is near the top electric heating tube being arranged in the top delivery port, utilize near the hot water of top electric heating tube local heat top delivery port, to satisfy the requirement that the user uses hot water in a large number.Temperature switch is arranged near the hot water outlet above the top electric heating tube, and the 3rd electric heating tube is the middle part electric heating tube that is arranged in the middle part.
The operation principle of water heater is: divide three sections heating.Without hot water or hot water consumption hour, mainly use the bottom electric heater for heating, form the convection current of the hot and cold water of whole inner bag, obtain the hot water of a whole courage.During the hot water large usage quantity, mainly with the top electric heating tube heating, the convection current of hot and cold water only limits to top area, and the temperature of water raises very fast, helps improving hot water output.
As for selecting top electric heating tube on earth still is the bottom electrical heating tube, and still three pipes are opened together, can the people realize for the manual operation gauge tap.
The invention has the beneficial effects as follows: at first be energy-conservation.Because adopt the method for dividing two sections heating, the temperature of water heater can be turned down a bit at ordinary times, also helps energy-conservation.In case the hot water consumption heightens, the top water heater working heats up rapidly, has guaranteed instructions for use.And the prior art scheme often needs to transfer the temperature of water heater very highly in order to satisfy a large amount of needs that use hot water, is unfavorable for energy-conservation.The secondth, help the water heater miniaturization.Especially two-tube when opening together, the firing rate of water is very fast, helps the water heater miniaturization.And the prior art scheme generally is to satisfy big traffic demand to improve the water heater liner volume.The 3rd is along with the water heater miniaturization, has saved material, and along with the reducing of outer cover of water heater area, area of dissipation reduces thereupon, more helps energy-conservation.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the front section view of the specific embodiment.
1. totally-enclosed water-storage electric heater shells among the figure, 2. cold water pipe, 3. hot-water line, 4. bottom electrical heater, 5. middle part electric heater, 6. top electric heater.
The specific embodiment
Utilize the essential structure of a totally-enclosed water-storage electric heater of known family expenses, comprise that cold water pipe (2), hot-water line (3), shell (1), heat-insulation layer, volume are 40 liters pressure-bearing inner bag, form a water heater, inner bag pressure-bearing 0.8 MPa.Water heater liner is cylindrical, horizontal layout.
The supply voltage of bottom electrical heating tube (4) is 220 volts, 1250 watts of power.A temperature open pipe is installed in the water heater bottom, controls the bottom electrical heating tube specially.
Second electric heating tube is near the top electric heating tube (6) being arranged in the top delivery port, and this electric heating tube is to exchange 220 volts of power supplies, and 1250 watts, the band temperature switch is installed near the delivery port of top.This temperature switch is controlled top electric heating tube specially.
The 3rd electric heating tube is the middle part electric heating tube (5) that is arranged in the middle part, and voltage is 220 volts, 1250 watts of power.
Aspect control, each electric heating tube all has temperature switch control separately, does not disturb mutually, and is effectively simple.
Claims (1)
1. electric heater, it is characterized in that: utilize the essential structure of a totally-enclosed water-storage electric heater, comprise known shell, heat-insulation layer, pressure-bearing inner bag, temperature switch, two electric heating tubes, first electric heating tube is the bottom electrical heating tube that is arranged in the water heater bottom, second electric heating tube is near the top electric heating tube being arranged in the top delivery port, temperature switch is arranged near the hot water outlet above the top electric heating tube, and the 3rd electric heating tube is the middle part electric heating tube that is arranged in the middle part.
