Abstract

The invention relates to an energy-saving magnetic temperature-sensing pot lid. In the energy-saving magnetic temperature-sensing pot lid, most of the peripheral part is closed by aluminium alloy or stainless steel to form a cavity with proper thickness; insulation fiber with high heat insulation property or other hot poor conductors with low density are filled in the cavity; and part of air in the cavity can be pumped, so that loss of heat in a pot can be reduced. A plurality of small permanent magnets are symmetrically fixed at positions near the pot in the cavity, have moderate magnetic induction strength, and can increase pressure between the lid and the pot through attractive forces to the iron pot, so that sealing effect of the lid is enhanced, leakage of hot gas in the pot can be reduced, and a pot shovel can be fixed on the pot lid according to the magnetism. A small part in the center of the lid is made of organic glass, so conditions in the pot can be observed conveniently in the heating process and heat dissipation caused by opening the lid for multiple times is avoided. A double-metal-sheet small thermometer which can sense the temperature of the pot is arranged in a handle, so that the temperature of the pot can be sensed conveniently and fire can be controlled timely during heating. A layer of heat-resistant heat-insulating non-toxic film besides the organic glass can be coated on the inner surface or the outer surface of the lid, so that heat in the pot can be prevented from being dissipated in a radiation mode. Dissipation of heat in the pot is greatly reduced by various methods, so energy-saving and heat-preserving effects are prominent, the structure is novel and cost is low. The conditions in the pot can be observed conveniently and fire can be regulated and controlled timely during heat. The energy-saving magnetic temperature-sensing pot lid is applicable to kitchenware and can serve as a lid of an industrial heat receiver.

Description

A kind of energy-conservation magnetic temperature-sensitive pot cover

Technical field

The present invention relates to a kind of heating lid tool articles for use, particularly a kind of energy-conservation magnetic temperature-sensitive pot cover.

Background technology

Common pot cover is made of aluminium alloy or stainless steel solid, because metal is the good conductor of heat, causes a large amount of dissipation of pot interior heat, has wasted the energy and has also prolonged heat time heating time.The material that remains in pot very easily turns cold owing to the easy heat radiation of pot cover, and heating is not only wasted but also bother again.When in the pot during liquid boiling, the gas of generation is also easily froth jack-up and displacement, causes between pot cover bad sealing real, radiating and cooling.People take off lid during situation always in observing pot, heat is repeatedly lost.Slice separates with pot, and slice does not have suitable placement location.

Summary of the invention

This energy-conservation magnetic temperature-sensitive pot cover can overcome above deficiency, and its profile is similar to common pot cover.Peripheral most areas of lid seal into cavity by aluminium alloy or stainless steel, wherein fill the non-conductor of the little heat of the insulation fibre of an amount of excellent heat insulating performance or other density, and the air in the cavity can be extracted a part out, reduce a heat loss in the pot.Position symmetry near pot in cavity is fixed several little permanent magnets, their magnetic induction intensity is moderate, they to the attraction of iron pan can increase lid with pot between pressure, strengthened the sealing effectiveness of lid, hot gas minimizing in the pot is leaked, and its magnetic also can play the effect that slice is fixed on pot cover.The central sub-fraction of lid is made by the good lucite of light transmission, and the stronger anti-ability of falling is arranged, and is convenient in the heating process to observe the situation in the pot, avoids repeatedly taking off lid and dispels the heat, and also is convenient to fixed handle on the lucite.The bimetal leaf compact temperature meter of the built-in energy perception kettle temperature of handle is convenient to the fiery degree that the control in time of perception kettle temperature adds man-hour.The inner surface of lid or outer surface are coated with except the lucite part and post the in a large number heat-resisting heat insulation non-toxic film of reflected infrared raies of one deck, and heat scatters and disappears by the mode of radiation in the minimizing pot.

Advantage of the present invention is: by reducing in a large number pot interior heat with multiple means by conduction, and radiation, three kinds of modes of convection current and dissipating, energy-saving heat preserving and save time remarkably productively, structure is novel, and cost is lower.Fiery degree when being convenient to pot interior situation of observing and regulation and control heating in time.Be not only applicable to the cooker in kitchen, can be used as the lid tool of industrial thermoreceptor yet.Accompanying drawing 1 is a profile of the present invention.1 is the non-conductor of cavity and heat-insulating fiber or heat among the figure, and 2 is the heat insulation thin layer of reflected infrared ray, and 3 is lucite, and 4 is the handle of built-in temperature meter, and 5 is little permanent magnet.

Claims

1. this pot cover has energy-conservation magnetic and kettle temperature perceptional function, it is characterized in that: the cavity of the suitable thickness that its peripheral most of area is sealed by aluminium alloy or stainless steel, wherein fill the non-conductor of the little heat of the insulation fibre of excellent heat insulating performance or other density, air wherein is drawn out of a part.

2. it is characterized in that such as the invention in the right 1: the position symmetry near pot in cavity is fixed the moderate permanent magnet of several little magnetic induction intensity.

3. it is characterized in that such as the invention in the right 1: the central sub-fraction of lid is made by lucite.

4. it is characterized in that as the invention in the right 1: the little thermometer of the built-in energy perception kettle temperature of handle.

5. it is characterized in that as the invention in the right 1: the inner surface of lid or outer surface are coated with except that the lucite part and post one deck heat-resisting heat insulation non-toxic film of reflected infrared raies in a large number.

6. it is characterized in that as the invention in the right 1: it is only applicable to the cooker in kitchen, also can be used as the lid tool of multiple thermoreceptor.
