Abstract

The utility model relates to a temperature-regulating device for mattresses or sofas, comprising an air supplying chamber, an air heating furnace, a mattress or a sofa cushion and an air inlet pipe. Capable of supplying for hot air flow for warming up as well as cold air flow for cooling down, the utility model has the advantages of fast heating, low energy consumption, simple structure, low cost, high safety, reliability, etc., and is appropriate to serve the thermoregulation function for the mattress or the sofa.

Description

Adjustable temp. device for mattress or sofa

The utility model relates to the register that a kind of home-use register, particularly mattress or sofa are used.

Existing electric blanket only is suitable for warming oneself on the bed in winter and uses, and its shortcoming is that heating is slow, and child wets the bed and causing the electric leakage electric shock easily, and heating wire fractures easily, and service life is short, domestic air conditioning equipment manufacturing cost costliness, and power consumption is difficult for popularization and application greatly.

The purpose of this utility model is to overcome the shortcoming of above-mentioned technology, provides a kind of heating fast, and power consumption is few, low, safe in utilization, reliable mattress of cost or sofa use register more.

The utility model is achieved in that the utility model comprises that plenum chamber, air-heating furnace, mattress or sofa cushion and air inlet pipe thereof constitute.By housing, the secured core that is contained in the housing inner bottom part and coil, the movable core that in housing, can move, travel switch, have unidirectional air inlet to chew to constitute plenum chamber with the unidirectional receipts of chewing of the giving vent to anger formula air bag that changes.Receive repeatedly the formula air bag and make with rubber or plastics, its bottom fuses with movable core, the top of top and housing is fixed together.By having air inlet and gas outlet and the furnace shell that seals and electric furnace heating wire and supply socket to constitute air-heating furnace all around.The inside and outside wall of furnace shell is coated with thermal insulating coating.Constitute mattress or sofa cushion by the solid pipe joint on framework of framework, envelope, wire side, air inlet pipe and dress thereof.Framework is made with timber or metal material, air inlet pipe is made, is had above the tube wall many apertures with metal tube or plastic tube and is fixed on the framework with pipe joint, wire side is weaved into plastic tape or wire, and is tightened on the framework, envelope adopt cloth be layered on wire side above.By travel switch control coil switching electricity, the magnetic attraction movable core during energising, repeatedly the formula air bag is air-breathing thereby stretch to receive, and magnetic force disappears during outage, and the receipts that the are stretched formula air bag that changes shrinks and calms the anger.Reciprocal like this, plenum chamber is constantly sent into air after the interior heating of air-heating furnace, sends into the thermal current heating for mattress or sofa cushion by air inlet pipe.When the air-heating furnace no power, plenum chamber is sent constantly into air and is sent into the cool breeze heat radiation for mattress or sofa cushion through air inlet pipe.

The air-flow heating but the utility model had both heated winter, but send the cool breeze heat radiation again summer, heating is fast, and power consumption is few, and is simple in structure, cheap, safe in utilization, reliable.The temperature adjustment of suitable family expenses mattress or sofa is used.

The utility model further describes below with reference to the embodiment in the accompanying drawing:

Fig. 1 is a structure chart.By secured core 1, coil 2, stroke piece 3, movable core 4, travel switch 5, receive that repeatedly formula air bag 6, housing 7, unidirectional air inlet chew 8, unidirectional giving vent to anger chewed 9, air inlet 10, supply socket 11, electric furnace heating wire 12, furnace shell 13, gas outlet 14, flexible pipe 15, envelope 16, wire side 17, air inlet pipe 18, framework 19, pipe joint 20, spring 21, stopped up 22 and constitute.By secured core 1, coil 2, stroke piece 3, movable core 4, travel switch 5, receive that repeatedly formula air bag 6, housing 7, unidirectional air inlet chew 8, unidirectional giving vent to anger chews 9 and spring 21, stop up 22 and form plenum chamber.Secured core 1 adopts E type silicon steel sheet, and coil 2 usefulness lines directly are the enamel covered wire of 0.05-0.5mm, number of turn 1800-2500 circle.Secured core 1 and coil 2 are fixed on the bottom of housing 7, electromagnetic attraction 1-5Kg.Stroke piece 3 is contained on the housing 7 and removable accent stroke distances.Travel switch 5 dresses are solid on movable core 4, and in company with action, movable core 4 usefulness silicon steel sheets are made.Receive repeatedly formula air bag 6 usefulness rubber or plastics and make, its bottom cements in movable core 4, and the oral area of top and housing 7 is fixed together.Receiving repeatedly the top of formula air bag 6 has 1-3 unidirectional air inlet to chew 8 and unidirectional giving vent to anger to chew 9.Unidirectional air inlet chew 8 and unidirectional giving vent to anger chew 9 elastic force and make and stop up 22 and block the mouth mouth by spring 21.When receiving that repeatedly formula air bag 6 is stretched by magnetic force, make unidirectional air inlet chew 8 plug stifled 22 by vacuum pressure reduction and unclamp air inlet, at this moment unidirectional giving vent to anger chewed 9 and is plugged oppositely air inlet.When receiving repeatedly formula air bag 6 when coil 2 outage losss of excitation and shrinking, unidirectional giving vent to anger chewed 9 obstruction 22 and unclamped exhaust, and unidirectional air inlet this moment chews 8, and be plugged can not exhaust.Housing 7 usefulness steel or engineering plastics are made, and spring 21 usefulness spring steel wire coiled compression springs stop up 22 and adopt steel ball.Constitute air-heating furnace by air inlet 10, supply socket 11, electric furnace heating wire 12, furnace shell 13, gas outlet 14.Furnace shell 13 has air inlet 10 and gas outlet 14, and seals all around, and air inlet 10 is chewed 9 and is connected with unidirectional giving vent to anger.Electric furnace heating wire 12 is coiled in the furnace shell 13, and the two ends of electric Shanghai silk 12 is connected in the supply socket 11, and supply socket 11 dresses are solid on furnace shell 13.Electric furnace heating wire 12 adopts the nichrome wire of φ 0.35-φ 0.5mm, power 100-500W.Furnace shell 13 adopts metal or bakelite material to make, and inside and outside wall is coated with the thermal insulating coating.Commercially available 220V, the socket of 5-10A are selected in supply socket 11 for use.Constitute mattress or sofa cushion by envelope 16, wire side 17, air inlet pipe 18, framework 19, pipe joint 20.Air inlet pipe 18 usefulness metal tubes or plastic tube are made, and many air inlet apertures are arranged above, are fixed on the framework 19 with pipe joint 20.Wire side 17 is weaved into and is tightened on framework 19 with plastic tape or wire on air inlet pipe 18.Framework 19 usefulness timber or metal material are made.Envelope 16 usefulness clothes be layered on wire side 17 above.With plastic flexible pipe 15 gas outlet 14 and pipe joint 20 are coupled together.
