Description

Thermo-sensitive soft magnet automatic temp. controlling multi-purpose pot

The utility model relates to a kind of cooking pot.

The pot kind a lot, as frying pan, steamer, saucepan, pressure cooker etc., be widely used in occasions such as family and restaurant, and have the multipurpose characteristics the pot be particluarly suitable for using in the family.

Existing pressure cooker is by aluminium or stainless steel stretched moulding, on pot cover, is furnished with pressure limiting valve, utilize self gravitation, act on the relief hole, when pot inner pressure reaches certain limit, steam bears down on one and opens the outside exhaust of pressure limiting valve, when relief hole is blocked row when holding one's breath by foreign matters such as the grain of rices, to play the effect of safety anti-explosive at the acolite sheet that disposes on the pot cover: promptly when kettle temperature and pressure reach certain value, the acolite sheet is melted to be washed open, this pressure limiting, protective device is widely used in the production field of pressure cooker at present, have certain reliability, accepted by people over a long time.But the safety relief error of acolite sheet more greatly, greatly about about 20-40%, also waste rare metal simultaneously.

The purpose of this utility model is; Design and a kind ofly have the irony that to steam, fry, boil characteristics and use pot more, simultaneously the temperature-sensitive soft magnetic materials is utilized on the thermostat on the pot cover, change by temperature-sensitive soft magnetism induced magnetism, drive activity steel disc, open and close pressure control and lose heart, make it to play pressure limiting security personnel effect, make pot inner pressure, temperature controlling error about 1.5%, like this, cover the application target that pot cover can reach pressure cooker.

The purpose of this utility model realizes by following technical measures; The temperature-sensitive soft magnetism is temperature automatically controlled many with pot, comprise pot cover, pot body and be arranged on temperature-sensitive soft magnetism thermostat on the pot cover and manual drain valve and tensioner are formed at the magnetic cushion rubber at pot cover edge, temperature-sensitive soft magnetism thermostat is the cylindrical of sealing, the upper top of shell body has the arcuation open-work, its inner chamber is equipped with disk shape tuning fork from top to bottom respectively, ring-type ferrite permanent-magnet ring and the spring that is inserted between the temperature-sensitive soft magnetism ring of same horizontal circle and two with it.Outer rim is the movable steel disc that circle lacks shape and is close to permanent-magnetic clamp, and the bottom side of soft magnetism ring and spring is enclosed in top with above-mentioned parts, equally oppositely is contained in the permanent-magnetic clamp of another movable steel disc bottom with top, soft magnetism ring and spring, and its bottom side is attached on the shell of pot cover.

Advantage of the present utility model and good effect are:

1, utilizes the temperature-sensitive soft magnetism automatic temperature control device that is arranged on the pot cover to control kettle temperature accurately, improve boiling point (can reach 110 ℃) in the pot, save the energy.

2, pot cover is taken away to be used as cooking; The manual drain air valve of opening on the pot cover can be used as steaming, saucepan; When reaching 110 ℃, kettle temperature pronounces by tuning fork.Temperature in the report pot.

3, the pot body adopts 08F low carbon steel plate drawing and forming, easily processing, and price is low, and shell enamel coating or heat resistance paint make it attractive in appearance.

Below in conjunction with accompanying drawing specific embodiments of the present utility model is done detailed explanation:

As shown in Figure 1: pot body 2 of the present utility model adopts 08F steel plate drawing and forming, inner surface of pot body polishing or zinc-plated, outer surface is coated with heat resistance paint or enamel, burn-on at the pot body one place inner nut of outer-hexagonal, seal in phenolic aldehyde raw material cover screwing as pot handle by a stay bolt, dispose manual drain air valve 4 on pot cover 1, screw phenoplasts body on it, valve is just closed tight; Unscrew, valve just opens, by the compressing tablet gap gas in the pot is discharged.Also disposed the phenoplasts handle 13 that has inner bolt hole on the pot cover.At pot cover recessed along the place with fan-shaped magnetic cushion rubber 5 tensioners of special use, put.

The temperature-sensitive soft magnetism thermostat 3 that key technology of the present utility model is to dispose on the pot cover is shown in Fig. 2,3,4,5,6,7, it covers a pair of ferrite permanent-magnet ring 9, the temperature-sensitive soft magnetism ring 10 in it by a shell body 6 that has a pore and places spring 11 between two, and by movable steel disc 12 they are separated respectively, at the shell internal upper part of shell body 6 and a sheet tuning fork 8 is housed, when vapours reaches a level pressure, impact tuning fork and can send the sound equipment reminds people.After whole temperature-sensitive soft magnetism thermostat 3 has assembled, be tightened on the pot cover 1 with screw.

Shown in Fig. 8,9, the temperature-sensitive soft magnetism ring 10 in the temperature-sensitive soft magnetism thermostat 3 is made according to some ferritic saturation induction density and the temperature variant feature of initial permeability.

As shown in Figure 2, when kettle temperature was lower than the curie point (110 ℃) of temperature-sensitive soft magnetism ring 10 materials, movable steel disc 12 was attracted by temperature-sensitive soft magnetism ring 10, constitutes closed magnetic circuit, pore is sealed.

As shown in Figure 3, when kettle temperature reaches the curie point (110 ℃) of temperature-sensitive soft magnetism ring 10 materials, saturation induction density reduces to zero, promptly lose magnetism, this moment, spring 11 boosted movable steel disc 12 with ferrite permanent-magnet ring 9, by the round scarce air-flow conducting that makes in the edge of movable steel disc 12, at this moment superheated steam impact tuning fork 8 sends sound equipment, temperature in the report pot, simultaneously, gas is discharged outside the pot by the arcuation open-work on the shell body 67, after discharging superheated vapor, temperature is reduced to below the curie point, the saturation induction density of temperature-sensitive soft magnetism ring 10 is recovered, and promptly recovers magnetic, and attraction activity steel disc 12 seals pore once more, go round and begin again, make pot inner pressure remain on 0.4kg/cm ₂, temperature remains on about 110 ℃.

Another embodiment of the present utility model as shown in figure 10;

Set bolt 14 is at the inner chamber of pot cover, nut sleeve 15 is in pot cover 5 outsides, by hole prefabricated on the pot cover, bolt 14 is passed and is tightened on the nut sleeve 15, nut sleeve 15 inner chambers are respectively charged into temperature-sensitive soft magnetism ring 16 from bottom to up, permanent magnet ring 17 and movable steel disc 18, another group temperature-sensitive soft magnetism ring 16 is housed in contrast, permanent magnet ring 17 and movable steel disc 18, it is close with its envelope to be screwed in nut sleeve 15 tops by hold-down bolt 19.When kettle temperature was lower than the curie point (110 ℃) of temperature-sensitive soft magnetic materials, movable steel disc 18 was closed state by magnetic attraction, and when being higher than 110 ℃, magnetic force disappears and is opening.

The characteristics of present embodiment are: 1, can directly be screwed on the pot cover, needn't fix with Screw.2, saved the spring that is configured in the centre.
