Abstract

The utility model relates to a stewing pot, comprising a main pot with double pot walls and a subsidiary pot with double pot walls. A heat-insulating layer which takes the polyurethane foaming body as the heat-insulating intermediate material is arranged between an inner pot wall and an outer pot wall of the main pot. The utility model is characterized in that the inner surface of the inner pot wall of the main pot is additionally provided with a temperature-resistant heat-insulating layer to effectively prevent the high temperature of the subsidiary pot from directly transferring the heat to act on the heat-insulating intermediate material of the polyurethane foaming body, and the polyurethane foaming body can be prevented from ageing. The temperature-resistant heat-insulating layer is formed from the coating or the molding of the heat-insulating material such as silicon dioxide, asbestos, glass fibre, temperature-resistant resin, temperature-resistant paint, the polymer of silicate paint and ceramic powder, etc.

Description

Stewing pot

The utility model relates to a kind of thermos-cooker.

Because the progress of society, industrial and commercial prosperity, career woman's ratio is grown up every year now, the time that therefore general family is used for cooking is also shorter and shorter, even the busy cooking, often allow in the family child or the elderly do it yourself to do meal, but blunt because of child's ignorant or the elderly, what is heard is arranged when often causing unexpected tragedy such as fire, perhaps electrical appliance boils the worry that the also live wire of cooking a meal cocks off with the automatic control time of timer, be to fry and stew slowly mostly more with fast for fear of the Chinese custom that boils, and stew, the homely especially gimmick of stewed tonic, but also usually stew to such an extent that the excessive gas that extinguishes stove fire of soup juice leaks or dryly burns public harm such as on fire, therefore be to have a kind of city of asking of thermos-cooker to use recently to prevent contingency, and this thermos-cooker has a female pot and son pot, with the sealing in the water boil rear seal-cover is inserted female pot in the short time of food in the son pot, the high temperature that boils with sub-pan boiling by the thermal insulation of female pot from be about to food stewing ripe with insulation, but so except that the fuel saving energy, it does not use other heating tools and the tool security in the smoldering process, the temperature that more can keep food, thus recently thermos-cooker widely family adopt and be popular.

Commercially available thermos-cooker kind brand is a lot of, but its structural principle is roughly divided into two kinds, one is the vacuum heat-insulation formula, another is polyurethane (PU) foaming body heat-insulating type, wherein the vacuum heat-insulation formula is to be evacuated as thermal insulation layer in female pot the double boiler wall, its thermal insulation is good and smoldering efficient is also best, but this structure manufacturing is difficult for, the degree of difficulty height, relative cost is also high, the real non-general family of its price can accept, therefore also to adopt with polyurethane foaming body (POLYURETHANE) be thermal insulation layer to commercially available thermos-cooker, and its moderate cost is also easily popularized the market demand, and this pot of body designs as shown in Figure 1, have female pot 2 and one a son pot 3, and between the double boiler wall of female pot 2, inject the thermal insulation layer 4 that constitutes with polyurethane (PU) foaming body.

Yet, the initial purpose of material behavior of PU foaming body (POLYURETHANE) is cold insulation, because material retentivity is good at low temperatures for it, so be used in refrigerator mostly, freezing or refrigeration sexual function such as refrigerator-freezer, and the material that cold insulation is generally arranged also has the dual-use function of heat insulating ability concurrently, therefore be for the dealer with this PU foaming body as the thermal insulation layer in female pot in the thermos-cooker, the initial stage effect is also good, but material because of the PU foaming body, it at high temperature easily is out of shape embrittlement then for the softening receipts that contract and wears out, though it is placed in female pot double boiler wall and directly is not heated, but when sub-pan boiling boils, its temperature all reaches 100 ℃ of left and right sides high temperature, especially if contain oil in the food, its temperature may be above 120 ℃, this high temperature food is positioned in the PU foaming body smoldering or insulation a few hours, more quicken the aging degree of its embrittlement, it inserted female pot at 2 o'clock, (as shown in Figure 2) high temperature of son pot 3 directly is heated on PU foaming body 4 with the interior pot wall 21 of female pot 2 by son pot wall rapidly, through high-temperature heating repeatedly, it is aging that the softening from inside to outside gradually receipts that contract of PU foaming body 4 thermal insulation layers in female pot 2 are out of shape embrittlement then, thermal insulation reduces gradually, and then influence its smoldering effect, reduce its smoldering effect at last and can only become fireless cooker.

Therefore, failing to change with the PU foaming body in economy and marketability is under the heat-insulation and heat-preservation material, the purpose of this utility model is to provide a kind of thermos-cooker, in female pot, press from both sides between pot wall and PU foaming body and establish with a heatproof thermal insulation layer, to reduce being heated of PU foaming body, more can block the divergence loss of son pot heat, improve the stewing of thermos-cooker and boil efficient and service life.

The purpose of this utility model reaches as follows:

A kind of thermos-cooker, this thermos-cooker has female pot of pair of lamina pot wall and the son pot that is heated, and have the polyurethane foaming body thermal insulation layer between the interior pot wall of female pot and outer pot wall, it is characterized in that: the inner face of pot wall is provided with and is coated with or heatproof thermal insulation layer that the heatproof heat-barrier material of moulding is made in this mother's pot.

The purpose of this utility model can also following mode reach: described thermos-cooker is characterized in that: described heatproof thermal insulation layer is that the polymeric material that silica gel, asbestos or glass fibre, heatproof resin, temperature resisting paint and silicate paint add ceramic powders is made.

Effect of the present utility model is: the utility model pot wall inner face in female pot wall of thermos-cooker constitutes a heatproof thermal insulation layer, act on the PU foam insulation in order to block son pot high temperature heat, the permanent effect of heat insulation that keeps PU foaming body integrality, make stewing boiling all obtain breakthrough raising in efficient, function, timeliness and service life, especially this structure also can be used as the thermos cup use, the heatproof thermal insulation layer of pot wall acts on the PU foaming body with the elevated temperature heat that blocks the son pot in its female pot of mat, keep the permanent insulative properties of PU foaming body, make to reach best heat insulation effect.
