Abstract

The utility model relates to a coal stove wind door device with a timing device of alarm clock, which belongs to cookers with timing spectrum. A lever 1 which is controlled by a timer and can move up and down is arranged in a casing, and one end of the lever extends out of the casing. The timer can be controlled by an alarm clock to start at a fixed time. The coal stove wind door is additionally provided with a small wind door 2. The timer is fixed in the upper right direction of the coal stove. The lever is connected with a small wind door by a string 3. Therefore, the coal stove can be controlled to open the wind door at a fixed time. When fire is needed, the fire can be made to be excess. When users do not use fire on time, the wind door can be closed automatically. The timer is provided with a power socket and other electric appliances can also be controlled to switch on or switch off on time.

Description

Multipurpose time device for controlling wind gap and oven wind gap device

The utility model is made up of alarm clock timer and coal stove throttle setting, belongs to the cooking utensils of band timer.

Stepped on " the coal stove timing automatic fires device and comes out " literary composition in " Economic Information " newspaper transfer of technology one hurdle on April 19th, 1985.Introduced a kind of timing automatic in the literary composition and fired device, " be installed on the various family expenses stone coal kitchen ranges, can open vent automatically by preset time, when guaranteeing with fire, water is opened fire prosperous with it." because be the report of transfer of technology, do not introduce details.But roughly fire door can be subjected to the control of timing device and open automatically as can be known, but can not shut automatically.If the user can not go home for some reason on time, the coal of coal stove possibility clean burn light, even danger appears, the utility model designs for addressing the above problem.

Fixed-time control part of the present utility model is a timer by alarm clock control, and profile as shown in Figure 1.The 1st, can control the lever of air door by cord; The 2nd, the timer turn-knob; The 3rd, the timer operating rod; The 4th, alarm indicator; The 5th, end the turn-knob that makes a noise; The 6th, the plank table top; The 7th, wood screw; The 8th, the fixedly iron plate of under-chassis or plastic plate; The 9th, the under-chassis of being convenient to fix.Fixedly the flat board 8 of under-chassis should be flexible slightly, so that alarm clock is fixing easily, or takes out locking, correction time.

Fig. 2 represents, the lever in the timer, cam structure.On the rotation axis 1 of timer, install a cam 3 additional, can control lever 2 when cam 3 rotates is the upper and lower swing in center with rotating shaft 7.The escapement of timer or escape wheel 4 are by lever 9 controls that spring leaf 8 is housed, and spring pressure is on escapement or escape wheel.Lever 9 can be that rotate at the center with rotating shaft 10, and the other end is connected on the locking reed 11 of alarm clock to the device 12 that makes a noise.Other establishes can be the operating rod 5 that rotate at the center with axle 6, when its handle is stirred forward, can dial the reed 8 that is pressed on the lever 9 on 4, and it can freely be rotated.Even timer had twisted turn-knob (having gone up clockwork spring) and also has only and go to the locking device indication time when hour hands and could rotate when operating rod was dialled backward.

The contact part of timer should be set up a breach inclined-plane on the cam of control contact, when making timer turn-knob inhour turn round to the limit, normally open contact is off-state, and when timer started, normally open contact was closed gradually, and to regularly at the end, contact disconnects again.Two to three outlets can be established in front or side at casing, make it can control multiple electrical equipment.

Fig. 3 represents can be with the timer-operated door structure of above-mentioned alarm clock.The 2nd, the air intake tube, the 4th, can be subjected to timer-operated little air door.The 5th, the aperture on the air door can be with the control cord with above being hooked on for a short time.The 6th, little air inlet generally is advisable with 6～8 square centimeters, decides on the size of coal stove.The 3rd, the spring on the little air door.The 7th, demountable air door lid.The 1st, the pore of banking up a fire.The processing of little air door and little air inlet should be compared precision, coincide better when it is shut.Little air door roughly becomes 30 degree angles with the position of air inlet with level, so that control.If the former air inlet of coal stove is round, setting up said apparatus also, good seal gets final product.Also said apparatus can be installed in the next door of any fire door.

Fig. 4 represents to be installed in the mechanism on the common square fire door.The 1st, the door of banking up a fire, the 2nd, the air inlet when banking up a fire, the 3rd, fire door, the 4th, little air door, the 5th, little air inlet, the 6th, be connected in the lever on the little air door, the 7th, the little hook of connection cord 8, the 9th, spring, the 10th, little shutter support, the 11st, the axle of little shutter.

Fig. 5 represents to be used to control the situation of coal stove.The alarm clock timer is fixed on the coal stove upper right side, has the little air door of the lever of timer and coal stove the cord of little hook to couple together with a two.The position of timer should make the angle cord becomes 60 to spend with ground about.Also have the screw that can regulate length on the cord, adjusting screw is just closed little air door tight.Timer turn-knob counter-clockwise direction is turned round to the end, operating rod is pushed the timer controlled location, reserve when making a noise, promptly open the door the time, like this to the schedule time, the little air door of coal stove will be opened gradually.The advantage of door of blowing in gradually is when the coal stove temperature is low, and the reason intake is too big and do not make furnace temperature decline, causes stopping working.Little because of little air door incoming air area, so this moment, coal stove just burnt prosperously gradually, and it is little to consume coal.Person to be used takes cord during with fire, opens the stove door, and coal fire is very prosperous at once, can use, and wants 20 minutes ability to burn prosperous shortcoming to overcome in the past coal fire.If after timer started half an hour, the user failed to use fire for some reason on time, little air door can be closed again about 10 minutes gradually, opens little air door then again a little, closes gradually again.Like this, during this period of time use fire, it is prosperous that coal stove still can very fast burning, goes out not return as the user, neither can consume a lot of coals, can accidents happened yet, to fill up coal equally before banking up a fire, because of said apparatus is arranged.Can be enclosed in optimum condition to fire door, to save coal.

If the timer turn-knob is turned round and can be reached the extreme higher position to air door, then can control blow-on when long, regularly close stove.

The utility model, available existing 60 minutes timers and the repacking of common alarm clock.Structure as described in Figure 2, timer are stretched out the outer lever maximum pull of casing and can reached about 200 grams.Make out the required pulling force of little air door about 100 grams with suitable spring.As special production, the clockwork spring of timer suitably can be strengthened elastic force, make the lever pulling force bigger, then reliability is higher.The shape need of little air door and air inlet closes and coincide behind the door better, and it is thicker that material is wanted, and makes it not yielding.The available common spring wound alarm clock movement of alarm clock part, as use the transistor alarm clock movement, then need set up a locking reed as common alarm clock.
