Abstract
An electric heating appliance with phase-change heat accumulation is composed of casing, electric heater, temp. controller, time controller, sealed container in casing, and phase-changing material in said sealed container. The electric heater is surrounded by phase-changing material. It uses the electric energy in low valley period of electric power network to generate and accumulate heat. At high-peak period of electric power network, it releases the accumulated heat to maintain room temp. Its advantages are simple structure and high reliability.
Description
The present invention relates to electric heating device, particularly the heat accumulating type electric heating device.
In recent years, environmental pollution is serious day by day.In the winter time, the dust and the discharge of harmful gases that cause in coal heating of the main pollution source in northern China city.New pollution-free or oligosaprobic heating heating mode is badly in need of releasing in society.And the employing electric heating more and more is subjected to people's favor as electric heating oil lamp, electrothermal quartz tube warmer, electric heating devitrified glass radiation warmer etc.But, in China and even world wide, all there is the excessive problem of peak-valley difference of power supply network, seriously hindered the reasonable use of electric power, also hindered effective development of electric heating device simultaneously.Because using the time of this type of electric heating device heating mostly is when the overall grid load reaches peak value, the electrical heating time must with the heating time synchronized, thereby can aggravate the excessive problem of power network load peak-valley difference more.And the space heater of employing accumulation of heat form at home and abroad is not reported in the document.
In order to solve environmental pollution and the excessive problem of power supply network peak-valley difference, remedy deficiency of the prior art.Goal of the invention of the present invention provides a kind of electric heating appliance with phase-change heat accumulation.It can utilize the electricity of electrical network low ebb phase to make warmer heating, accumulation of heat, uses big rate of heat release that the heat of savings is emitted to keep indoor temperature when the electrical network peak period needs heat supply.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes as follows: a kind of electric heating appliance with phase-change heat accumulation, it comprises housing, electric heater unit, phase-change material, temperature controller, time controller.Its design feature is, described shell wall side is provided with shutter and exhaust door, shutter and exhaust door are opened by set damper control control, housing is built-in with support, be equipped with airtight container on the support, phase-change material is housed in the airtight container, electric heater unit is housed in the phase-change material and is fixed in the airtight container, the outer surface of airtight container is equipped with radiated rib and temperature controller, hull outside set-up time controller.
The present invention used in the electrical network low ebb time period for strictness control, and according to technique scheme, described time controller adopts and solidified the timing controller of time control program.
In order to make air carry out interior circulation, according to technique scheme, air inlet on the described shell wall side and exhaust door are located at same surface, are provided with radiant panel over against air inlet and air draft place.
Because it is heat storage medium that the present invention adopts with the phase-change material, makes the phase-change material accumulation of heat earlier by electric heater unit, and then the heat of holding is emitted.So just can utilize the electricity of power supply network low ebb phase at night to make warmer heating, accumulation of heat, to heat release heating during the power supply network peak period on daytime.Thereby the peak-valley difference of not only adjustable economize on electricity net load, and after adopting the electricity price peak valley phase to divide valency meter system, can save operating cost.Compare with prior art, the present invention is environmentally safe not only, and can fundamentally solve the problem of power supply network peak-valley difference.Have characteristics reasonable in design, simple in structure, easy to use, dependable performance, the bright prospects of exploiting market are arranged.
The invention will be further described below in conjunction with accompanying drawing and concrete embodiment.
Fig. 1 is the structural representation of an embodiment of the present invention;
Fig. 2 is the structural representation of the another kind of embodiment of the present invention.
Referring to Fig. 1, embodiment 1 space heater of the present invention comprises housing 1, the phase-change material 3, temperature controller 10, the time controller 11 that constitute by the electric heater unit 4 of ceramic electric heating bar construction, by acieral.Be provided with shutter 6 and exhaust door 9 on the same surface of housing 1 wall, shutter 6 and exhaust door 9 are opened by set damper control 12 controls, are provided with radiant panel 7 over against shutter 6 and exhaust door 9 places.Housing 1 is built-in with support 8, is equipped with airtight container 5 on the support 8, and phase-change material 3 is housed in the airtight container 5, electric heater unit 4 is housed in the phase-change material 3 and is fixed in the airtight container 5.The outer surface of airtight container 5 is equipped with radiated rib 2 and temperature controller 10.Housing 1 outside has installed and fixed time control procedure time controller 11.Use when of the present invention, could regularly start the night that time controller 11 was solidificated in the electrical network low ebb phase, can economize like this with timesharing and remember the valency ammeter.After electric heater unit 4 was connected power supply, phase-change material 3 began to heat up and melts.When phase-change material 3 melted fully, temperature controller 10 made electric heater unit 4 stop heating.At this moment heat is mainly stored in the latent heat mode by phase-change material 3.Indoor need heating in, open exhaust door 9 and shutter 6 makes warmer begin external heat release by damper control 12.Liquid phase-change material 3 solidifies gradually, emits heat of solidification simultaneously.Because the approximate constant temperature process of phase transition process, latent heat of phase change is bigger, so even also can be similar to the isothermal heat release long period under cold situation.In exothermic process, shutter 6 and exhaust door 9 circulate hot-air in housing 1 and between the radiant panel 7, pass through radiant panel 7 again to indoor heat radiation.
Referring to Fig. 2, another embodiment of embodiment 2 space heater of the present invention.Omit narration with the foregoing description 1 same section.Different is with the foregoing description 1, removes radiant panel 7, and the position of shutter 6 can be located at other place of housing 1.In exothermic process, open exhaust door 9 and shutter 6 directly to indoor heat radiation by damper control 12.
According to the technical scheme of the various embodiments described above, if electric heater unit 4 is to be made of electrothermal tube or resistance wire or other form thermo electric material; Phase-change material be by other can latent heat, the material of heat transfer constitutes; In embodiment 2, ventilating fan is installed at exhaust door 9 places, by ventilating fan from exhaust door 9 to indoor heat transfer.Technical scheme such as a class all belongs to protection scope of the present invention.
