Abstract

The utility model provides a thermoelectric energy-saving domestic pot, which comprises a pot body and a heating plate arranged below the pot body and supported by a bracket, and is characterized in that thermoelectricity chip is arranged below the heating plate, and the chip is a semiconductor chip connected with a direct current; the hot end of the chip is jointed with the heating plate, and the lower end of the chip is provided with an energy collector capable of collecting the heat energy around; moreover, a small axial flow fan is arranged below the energy collector. By combining the electric heating technology and the thermoelectricity technology, the utility model improves the heating method of the prior art; apart from the heat energy generated by the electric heating effect under effect of the current, the heat can be produced from that the energy collector transforms the heat energy around into the heat energy of the heating plate. Hereby, the utility model makes the heat factor between 1.2 and 1.5, and saves electricity energy by 20 percent to 30 percent, thereby improving the heating efficiency. With simple structure and easy implementation, the utility model is an energy-saving product with high efficiency and possesses extensive application prospect.

Description

Thermoelectric domestic energy-conserving pot

Technical field:

The utility model relates to cooker for kitchen use, is specifically related to a kind of electric food warmer that comes transferring heat energy by electrothermal method.

Background technology:

Employed all kinds of electric food warmers generally all are to adopt heating as heating element heater at present, by electric current element heating are reached and boil the purpose of burning food or dish, as electric cooker, chafing dish etc.Though the heating of this series products is fast, easy to use, because its heating efficiency is less than 1.0, power consumption is higher, is a kind of not energy-conservation product.

The utility model content:

Technical problem to be solved in the utility model provides a kind of thermoelectric heatpump type domestic energy-conserving pot of energy-efficient, safe ready.

Technical problem of the present utility model is to realize by following technical scheme, it comprises pot body and places under this pot body and by the heating plate of bracket supports, it is characterized in that having thermoelectric chip at heating plate, this chip is a semiconductor chip that joins with direct current, its hot junction and heating plate are fitted, the energy collector that can collect surrounding environment heat energy is established in the lower end, and a small-sized axial flow fan is arranged under this energy collector.

The utility model combines by making electroheat technology and pyroelectric technology, mode of heating in the prior art is improved, its heat is except that the heat energy that produces because of electrocaloric effect under the function of current, also can the heat energy of surrounding environment be converted to heating plate heat energy by thermoelectric chip by energy collector, the pyrogenicity coefficient is reached between 1.2～1.5, can save 20%～30% electric energy, improve heating efficiency.The utility model is simple in structure, realizes easily, and be a kind of efficient energy-saving product, have broad application prospects.

The 4-energy collector; The 5-blower fan; The 6-support.

The specific embodiment:

The utility model is the improvement of being carried out on existing electric food warmer basis, it comprises pot body 1 and heating plate 2, heating plate 2 places under pot body 1, by support 6 supportings, it is characterized in that one thermoelectric chip 3 being set for 2 times at heating plate, this chip is made by semi-conducting material, it is by little chip component units parallel with one another more than two or two, the chip integral body of connecting mutually by each unit again and forming, join with direct current, under the direct current effect, its upper and lower end face forms cold junction and hot junction, by the characteristic of the thermoelectric energy conversion that semi-conducting material had, the heat that cold junction absorbs can be delivered to the hot junction heat release, produce the heat pump effect, the temperature range at two ends is between 100 ℃-120 ℃.Its concrete structural design of the utility model is that thermoelectric chip 3 hot junctions are fitted in heating plate 2 bottom surfaces, can be directly with thermal energy transfer to heating plate 2, one energy collector 4 is set below its cold junction, it is one can absorb the device of surrounding environment heat energy, and this part heat energy can be reached the cold junction of thermoelectric chip 3, to the heating plate 2 of fitting with its hot junction, the heat energy that produces with electrocaloric effect becomes heating plate 2 heating heat energy together jointly in this thermal energy transfer under the heat pump effect.Like this, the heat energy that is used to heat just is made up of two parts, the first produces the heat energy that the heating plate 3 of heat is produced by the input electric energy, i.e. the heat energy that is transformed by electrocaloric effect, and it two is to be transferred on the hot junction under the heat pump effect and then to be delivered to heat energy on the heating plate 2 by thermoelectric chip 3.For absorbing surrounding environment heat energy better, the utility model also has a small-sized axial flow fan 5 at energy collector 4, can faster, more direct amount of heat be passed to energy collector 4, to improve energy-saving effect.
