The utility model content

The purpose of this utility model provides a kind of new electrically heating coffee pot, and the traditional hot electric coffee maker has remarkable energy saving effect relatively.

For reaching above purpose, solution of the present utility model is:

A kind of new electrically heating coffee pot comprises heater block, heating water tank, and this heater block is a semiconductor refrigeration chip, and the face that heats of this semiconductor refrigeration chip directly contacts with the wall of heating water tank.

Further, also comprise the thermal-arrest plate, be distributed with some thermal-arrest fins on this thermal-arrest plate, the chill surface of this semiconductor refrigeration chip is close to this thermal-arrest plate.

Also comprise blower fan, its be arranged on the thermal-arrest fin below.

Also comprise cup for infusing and steeping, thermos cup, the outlet pipe of heating water tank links to each other with the water inlet of this cup for infusing and steeping, and the delivery port of this cup for infusing and steeping links to each other with the water inlet of this thermos cup.

Also comprise the resistance heated dish, its position is near this thermos cup.

Also comprise the vertoro and the power governor that link to each other with semiconductor refrigeration chip.

Concrete, the utility model can be by base, blower fan, semiconductor refrigeration chip, the thermal-arrest plate, the thermal-arrest fin, water tank, cup for infusing and steeping, thermos cup, the resistance heated dish, vertoro, power governor is formed, the hot side of semiconductor refrigeration chip up, huyashi-chuuka (cold chinese-style noodles) down, hot side water direct and in the water tank contacts, huyashi-chuuka (cold chinese-style noodles) is close to the thermal-arrest plate, be distributed with many thermal-arrest fins on the thermal-arrest plate, blower fan be contained in the thermal-arrest fin below, can enter cup for infusing and steeping by adjutage in the water tank, the coffee that soaks in cup for infusing and steeping can flow in the thermos cup, the resistance heated dish places body, the position is near the thermos cup place, vertoro and power governor are arranged in the body, and water enters by water inlet in the water tank, and the residue water is discharged by discharge outlet 6.

Owing to adopted above technical scheme, the utlity model has following beneficial effect:

Adopt semiconductor refrigeration chip to heat, semiconductor refrigeration chip connects direct current, its hot-face temperature raises fast and heat can be reached rapidly in the water of water tank, its huyashi-chuuka (cold chinese-style noodles) is close to the thermal-arrest plate, under the effect of thermal-arrest fin and blower fan, can absorb airborne heat, and be used for heat food, therefore its Energy Efficiency Ratio can reach about 1.5, promptly consumes the thermal effect that adds that 1 part of electric energy can obtain 1.5 times.Therefore relative traditional hot electric coffee maker, it can save energy about 33%.The utility model simple structure, volume is little, in light weight, easy to use, energy-saving effect is remarkable, will have boundless market prospects.
