Description
Technical field
The invention belongs to the kitchen range technical field, relate to the thermostat of a kind of gas-cooker, particularly gas-cooker.
Background technology
Attractive and durable and the cleaning of gas-cooker, so it is widely used as a kind of kitchen range.In order in gastronomical process, to control the size of firepower in real time, make to be always moderate moisture in the cooking process that the place is provided with electronic temperature control unit at burner.
Through long-term exploration and research, people have designed various electronic temperature control units, and wherein having a kind of is to be connected to electronic temperature measurement device on the handle by being embedded in electronic probe in pot body, can regulate and grasp the temperature of pot body intuitively.When firepower is excessive, pot is removed from burner, and the air valve of pulling the air inlet pipe place reduces air inflow; When firepower is too small, pulls the air valve at air inlet pipe place and air inflow is transferred big.As can be seen, this attemperating unit can not be regulated the firepower size automatically, and because the pot body is heavier, and labour intensity is bigger in cooking process, very inconvenience seems in actual the use.
For this reason, people have designed and a kind ofly can regulate the attemperating unit of firepower size automatically.For example, a kind of " the automatic safety gas kitchen ranges " that China Patent No. 03209624.0 provides, it is to be equiped with a temperature detect switch (TDS) and a magnetic valve that links to each other with temperature detect switch (TDS) at the center of burner, magnetic valve is contained in that to link to each other with burner be on the air inlet pipe.When temperature was too high, temperature detect switch (TDS) disconnected and to make closed electromagnetic valve, thereby makes combustion gas enter the burner place by air inlet pipe.The temperature control switch can change the opening degree of magnetic valve when temperature is high slightly, that is to say to make a spot of combustion gas enter the gas-cooker place by air inlet pipe, thereby makes firepower reduce.
Usually, the circular bottom pot that has of culinary art usefulness also has pan, and the bottom of a pan and the distance between the burner of circular bottom pot are shorter, and the bottom of a pan of pan and the distance between the burner are long slightly.When using different pots, the temperature detect switch (TDS) in the above-mentioned gas kitchen ranges just might can't be close to the bottom of a pan, the feasible temperature that can't normally monitor the bottom of a pan, and finally making does not have suitable firepower in the cooking process.
Simultaneously, when temperature detect switch (TDS) stretches out burner when longer, the fire at burner place can directly heat temperature detect switch (TDS).Like this, the temperature that just makes temperature detect switch (TDS) survey is inaccurate, normally uses and influence gas-cooker.
Summary of the invention
The objective of the invention is at existing in prior technology the problems referred to above, a kind of thermostat of simple in structure, gas-cooker that stability in use is high is provided.
Purpose of the present invention can realize by following technical proposal: a kind of thermostat of gas-cooker, be arranged on the burner place of gas-cooker, the air inlet pipe of joining with burner is provided with igniter and air valve, this attemperating unit comprises magnetic valve and control circuit that is located on the air inlet pipe, magnetic valve links to each other with control circuit, it is characterized in that, be provided with the temperature-sensing probe that links to each other with control circuit in the described burner, the outside of temperature-sensing probe is with heat shield, described temperature-sensing probe and heat shield can move up and down with respect to burner, and are provided with the elastic body that temperature-sensing probe and heat shield are moved up on burner.
In cooking process, by the temperature in this attemperating unit monitoring the bottom of a pan, thereby the firepower size of regulating burner accordingly makes to be always moderate firepower in the cooking process.
Particularly, temperature-sensing probe and heat shield move above burner and temperature-sensing probe is close to the bottom of a pan under the effect of elastic body, and the temperature at place, the bottom of a pan just can be detected by temperature-sensing probe.Because temperature-sensing probe links to each other with control circuit, control circuit just can be controlled valve opening solenoid degree of leaving.
When temperature-sensing probe detects the temperature at the bottom of a pan place when too high, it is less that control circuit just can make the opening degree of magnetic valve, and correspondingly feasible to enter the gas quantity at burner place by air inlet pipe less, so just makes that the firepower of burner is less; On the contrary, when temperature-sensing probe detects the temperature at the bottom of a pan place when low, control circuit just can make the opening degree of magnetic valve for bigger, and correspondingly feasible to enter the gas quantity at burner place by air inlet pipe more, so just makes that the firepower of burner is bigger.As can be seen, the temperature in the bottom of a pan is moderate in cooking process, thereby can cook out delicious food.
In addition, under the effect of heat shield, the flame at burner place can not make temperature-sensing probe can survey cooking bottom temperature accurately directly with the temperature-sensing probe heating.
In the thermostat of above-mentioned gas-cooker, heat shield is slightly stretched out in the end of described temperature-sensing probe.Such structure makes to have only the end of temperature-sensing probe to contact with the bottom of a pan, makes it can survey the temperature in the bottom of a pan more accurately.
In the thermostat of above-mentioned gas-cooker, described temperature-sensing probe is positioned at the center of burner.
In the thermostat of above-mentioned gas-cooker, described elastic body is the spring that is enclosed within the temperature-sensing probe bottom, the two ends of spring act on respectively on heat shield and the burner, above-mentioned heat shield and temperature-sensing probe can relatively move, and be provided with back-moving spring between heat shield and temperature-sensing probe top, the two ends of back-moving spring act on respectively on temperature-sensing probe and the heat shield.
Under the elastic force effect of spring, heat shield can move up, owing to also be provided with back-moving spring between heat shield and temperature-sensing probe, so heat shield and temperature-sensing probe can together move up.Simultaneously, under the effect of back-moving spring, when the pot body was placed on the burner, the bottom of pot body at first contact with the end of temperature-sensing probe, and the gravity of pot body self after overcoming the elastic force of back-moving spring presses down temperature-sensing probe; Then, the pot body contact with heat shield again and overcome the elastic force of spring after heat shield and temperature-sensing probe are together pressed down.That is to say, adopt such structure can guarantee that temperature-sensing probe can stable and accurate detection cooking bottom temperature, can not be subjected to the flame influence at burner place again.
As second kind of scheme, in the thermostat of above-mentioned gas-cooker, described elastic body is the spring that is enclosed within the temperature-sensing probe bottom, and the two ends of spring act on respectively on temperature-sensing probe and the burner, and above-mentioned heat shield is connected mutually with temperature-sensing probe.As can be seen, under the effect of spring, temperature-sensing probe can move up, because heat shield is tightly to be enclosed within on the temperature-sensing probe, heat shield also can be along with temperature-sensing probe together moves up.
In the thermostat of above-mentioned gas-cooker, described control circuit is made up of central processing unit, temperature control button and temperature indicator, and temperature control button and temperature indicator all join with central processing unit.Described temperature control button adjustable settings temperature, described temperature indicator are used for the actual temperature that display setting temperature and temperature-sensing probe are surveyed, and can control the opening degree of above-mentioned magnetic valve after described central processing unit comparison design temperature and the actual temperature.
The temperature that temperature-sensing probe is surveyed transfers to the central processing unit place by lead, and the opening degree of above-mentioned magnetic valve is changed.That is to say that when cooking bottom temperature was too high, it is less that central processing unit can make the opening degree of magnetic valve change into; Cooking bottom temperature is crossed when hanging down, and it is bigger that central processing unit can make the opening degree of magnetic valve change into.So just correspondingly changed the gas quantity that enters the burner place by air inlet pipe.
Compared with prior art, the thermostat of this gas-cooker can make temperature-sensing probe can be close to the bottom of a pan, and is with heat shield in the outside of temperature-sensing probe.So just make temperature-sensing probe can survey the actual temperature in the bottom of a pan accurately, obviously, its stability in use cooking bottom temperature higher, that survey is more accurate.
Certainly, because it can survey the actual temperature of pot body accurately, therefore, reached energy-saving and cost-reducing effect accordingly.
Simultaneously, it just is with heat shield in the outside of temperature-sensing probe and the temperature-sensing probe place is provided with spring, and therefore, its structure is also fairly simple, and is easily manufactured, cost is lower.
