Abstract

The utility model relates to a circular jet spread cold and hot air blower for adjusting indoor temperature. A semi-conductor electric pile in a box body is used for refrigeration or heat supply, and an assistant heat supply device has the performances of constant temperature and overheating protection; cold and hot air are circularly and outward sparged by a wind collecting cover of a minitype oscillating fan circular mode from an air outlet fence of a panel; a switch control system with an intermittent type is used for adjusting circular speed and temperature.

Description

Circular jet spread cold & hot air blower

The utility model is an indoor temperature regulating device.

Existing temperature-adjusting device has the traditional mechanical refrigeration air-conditioner and the air-cooler of compressor system, also has in recent years popular cold-warm fan both at home and abroad, and description is various.Cold-warm fan particularly, structural principle basic identical (see " electric fan user's manual ", light industry publishing house, publish in December, 1985).

Prior art also has cold-hot dual purpose fan No. the 46th, utility model patent communique 1986 second volume (see the 29th page).

The utility model provides a kind of indoor use, has the safe and reliable circulation spray cloth formula Cooling and heating blower of refrigeration, heating performance.

The utility model has a semiconductor pile and auxiliary heat supplying device, has the small-sized oscillating fan of wind gathering cover and the barge board of certain altitude.Control by power-supply system and discontinuous switching system.

Operation principle of the present utility model and structure accompanying drawings are as follows:

Fig. 1: circulation spray cloth schematic diagram.

Fig. 2: structural representation.

Fig. 3: electric control theory figure.

With reference to accompanying drawing: in the enclosed housing (5) that insulating plastic pipe is made, small-sized oscillating fan (4) is housed, wind gathering cover (3) is for having only the semi-closed structure of a center air outlet.The outlet grid width of panel (1) and wind gathering cover (3) air outlet diameter are basic identical.Semiconductor pile (8) has the Peltier effect characteristic, is used for freezing or heat supply.PTC semiconductor element (7) has constant temperature and superheat protecting function, as the auxiliary heat supplying device, is contained in same direction face with semiconductor pile (8).By changing the polarity of pile power supply, just can freeze or heat supply.And the refrigeration of whole system and heating load can be made up and regulate easily.There is the barge board (6) of certain altitude requirement to form jointly between a cold and hot air with pile (8), auxiliary heat supplying device (7), air is entered in the casing (5) by the adjustable solar term discharge orifice (10) of base plate, air-flow is sucked by the guard at oscillating fan (4) rear portion, semiclosed cover by the front portion, make it produce certain polymerization and pressure, outwards spray cloth through the air outlet of wind gathering cover (3) from the outlet grid of panel (1), thereby strengthened the esthesis of cold and hot air.The motor of discontinuous switching system control fan (4), thereby can obtain continuously or discontinuously by the cold wind or the hot blast of 90 ° of directions circulation spray cloth.Space mounting radiator and pile power-supply system (9) that the substrate of semiconductor pile (8) and auxiliary heat supplying device (7) and back shroud (12) are formed, have hole, air channel (11) at the base plate rear portion, back shroud (12) has large-area air outlet, guarantees distributing of internal heat.The box component material is engineering plastics.

In Fig. 3, PTC element (7) switches on or off by switch (16); Fan electromotor (4) is subjected to controllable silicon (14) control, dials to continuous position 1. the time when switch (15), and controllable silicon (14) obtains triggering signal by resistance (17), and motor moves continuously.When switch (15) is dialled to discontinuity position 2. the time, the astable circuit that triode (26), (30) etc. are formed, make them take turns conducting and ending, triode (33) also constantly provides triggering signal to controllable silicon (14), thereby makes fan electromotor obtain discontinuous operation control.Numerical value levelling by to element (24), (25), (27), (29) can make triode obtain different conducting and deadline.When switch (15) is dialled to discontinuity position 3. the time, because detector unit (38) and element (39), (48), (49) are formed bridge for measuring temperature jointly, and make temperature signal pass through the amplifier that element (40) to (47), (50), (51) form to go later on to trigger the reverse-blocking tetrode thyristor system, make the small-sized oscillating fan can be according to variation of temperature and automatic discontinuous carrying out.The power-supply system (9) of semiconductor pile (8) is formed in transformer (35) and rectifier and element (36), (37).Switch (37) is used for controlling the running status of pile (8), dials to the position 1. the time when it, and pile (8) moves as refrigerator; Dial to the position 2. the time when it, pile (8) moves as heater.Thereby the conversion of the refrigeration of realization or heat supply.

The utility model when environment temperature is about 35 ℃, was switched on several minutes when refrigeration, in certain air line distance, can obtain to be lower than the cold air of 5 °-8 ℃ of environment temperatures.When heat supply, switched on several minutes, can in certain air line distance, obtain to be higher than the hot blast of 30 °～40 ℃ of environment temperatures (about 5 ℃).Machine volume is 412 * 300 * 230mm, and is simple in structure, and noiselessness is easy to use, and the life-span is long.
