Abstract

The utility model relates to a refrigerating and air-exchange electric fan, which combines an electric fan, an air-exchange fan, and an air conditioner into integration, and can be supplied for the use of cold air blowing and the indoor and the outdoor air exchange. The utility model is composed of an axial current and direct current blower fan, a thermoelectric refrigerator, a side ventilation channel, a vertical ventilation channel, a central ventilation channel, and an air-exchange valve piece; a power supply is used for controlling a switch; air currents can flow along each ventilation channel forwards or backwards to make the refrigerated air current exhausted from the ventilation opening of the side ventilation channel or an upper ventilation opening. The purpose of cool enjoying can be reached. When the valve piece is opened, the air exchange can be carried out forwards and backwards, the indoor air can be kept fresh. The utility model has the advantages of simple structure, and low total cost.

Description

Refrigerating scavenger electric fan

The utility model belongs to a kind of ventilation electric fan.

In the modern life, people are in order to create a comfortable and nice and cool environment during the broiling summer, once design many different performances, different capacity and in specie electric fan, air conditioner not, bring in various degree enjoyment to the mankind; In addition, in order to make indoor frequent maintenance fresh air, people have also invented ventilation fan and have improved indoor environment, the contribution of these facilities is many generally acknowledges, each tool eternal lasting of its excellent characteristics, but their common shortcomings are function singlenesses, gross investment price height is installed complexity, and it is big to occupy the interior space.

The purpose of this utility model task provides all characteristics of a kind of current collection fan, air conditioner and ventilation fan in the equipment of one, to solve above-mentioned gross investment price height, install complicated and to occupy problems such as the interior space is big.

Above-mentioned task is finished according to following measure: it comprises the axial flow dc fan, TEC, airflow control mechanism and power controling machine structure, this TEC is outside with its hot junction, cold junction is inwards around the periphery that is installed in the axial flow dc fan, constitute a ring-type refrigerator, its airflow control mechanism is by the side ventilation flue, perpendicular ventilation flue, central ventilation road and last, following ventilated port and valve sheet are formed, this side ventilation flue is a ring-type, place the top of refrigerator, its outer side surface has several ventilated ports, the inboard end, be connected with the drum type barge board, and make the perpendicular ventilation flue of the adjacent formation of interior heat exchanger of drum type barge board and refrigerator; The internal diameter of cylinder barge board is the central ventilation road; The upper base of central passage is last ventilated port, goes to the bottom to be following ventilated port, all intercommunications between each ventilation flue; Be the control air flow direction, on the ventilated port valve sheet be installed down; Control box and double-pole power switch that the power controling machine structure of control TEC and the work of axial flow dc fan is made up of transformer and rectifier constitute, and are connected on the circuit of axial flow dc fan and TEC.

Above-mentioned TEC is made up of circular thermopile and the inside and outside heat exchanger of ring-type, and this thermopile mainly is made of array P-type semiconductor and N-type semiconductor, and inside and outside heat exchanger is installed in the inside and outside both sides of thermopile, and all is the dentation heat exchange surface.

On the last ventilated port of this refrigeration ventilation electric fan mat is installed.

Below in conjunction with description of drawings detailed structure of the present utility model:

Accompanying drawing is the cross-sectional view of refrigeration ventilation electric fan, wherein 1 is the axial flow dc fan, place central authorities, 2 is TEC, with its hot junction outwards, cold junction is inwards around axial flow dc fan periphery, the thermopile of this TEC is made of array P-type semiconductor 3 and N-type semiconductor 4, and internal-external heat exchange device 5,6 is installed in the inside and outside both sides of thermopile, all is dentation heat and hands over hot side; Ring-type side ventilation flue 7 is put the TEC top, its outer side surface has several ventilated ports 8, the inboard end, be connected with drum type barge board 9, drum type barge board 9 and the perpendicular ventilation flue 10 of the adjacent formation of interior heat exchanger of refrigerator, the internal diameter of barge board 9 constitutes central ventilation road 11, and the upper base in central ventilation road is last ventilated port 12, go to the bottom to be following ventilation road junction 13, but all intercommunications of above-mentioned each ventilation flue; Be the control airflow direction, valve sheet 14 is equipped with at the following ventilated port place in central ventilation road, is protection axial flow dc fan, and guard 15 is equipped with at the last ventilated port place in central ventilation road; Control box 16 and double-pole power switch 17 that the power controling machine structure is made up of the rectifier of transformer constitute, its may command air-flow and electric current to just, contrary both direction flows.

This refrigeration ventilation electric fan can be installed on house door or the window, also can be installed on the wall in the normal movable place of people, its working principle is: during the work of axial flow dc fan energising forward, valve sheet 14 on the following ventilated port can be closed also and can be opened, when valve sheet is closed, air-flow can enter from the ventilated port 8 of side ventilation flue, flow downward along perpendicular ventilation flue 10, at this moment, because of TEC is being worked, heat exchanger can make the heat absorption in the air-flow gas flow temperature reduce in it, air-flow after the cooling 11 upwards flows along the central ventilation road again, from last ventilated port 12 fan-outs, forms one cold airflow; When the reverse work of axial flow dc fan, airflow direction is reverse flow also, and the cold airflow after the cooling can be from 8 dischargings of the ventilated port on the side ventilation flue; When this refrigeration ventilation electric fan was installed on door and window, it is outdoor that outer heat-exchanger 6 is placed, and the side ventilation flue is put indoor, except that above-mentioned two kinds just, the inverted draft work, but Open valve sheet 14 also, make indoor and outdoor air just, contrary two to exchange.

The utility model can one the many usefulness of fan, the ventilating fan of both can having done to take a breath uses, the electric fan that can do to blow on or air conditioner use again, it is simple in structure, and is easy to operate, cost price is low, the occupied space of indoor installation is few, the form structure exquisiteness can be beautified dwelling house.
