Description
Technical field
The electric pressure cooking saucepan that the utility model relates to a kind of heat insulating member and has this kind heat insulating member.
Background technology
Existing electric pressure cooking saucepan comprises parts such as shell, middle ring, outer pot, and the directly contact successively of outer pot, middle ring, shell.This outer pot is the higher material of pyroconductivity, for example metal material.Should can contact (face contact) with the outer ring surface of outer pot by its inner ring surface by middle ring, also can contact (a line/contact) with the outer ring surface of outer pot by the rib limit on the anchor ring that sets within it.
The weak point of this electric pressure cooking saucepan is: owing to outer pot, middle ring contact successively with shell, if middle ring and outer pot all adopt the higher material of pyroconductivity, then when using this electric pressure cooking saucepan, the heat of high temperature outer pot will conduct to outer pot via middle ring, causes the temperature of outer pot to raise and the scald user.Therefore the security of this pot is relatively poor.
The utility model content
First technical problem that the utility model need solve provides a kind of heat insulating member, make when the middle ring of electric pressure cooking saucepan and shell all adopt the high material of pyroconductivity, the heat that can prevent outer pot through in ring conduct to shell, improve the security of electric pressure cooking saucepan.
Second technical problem that the utility model need solve provides a kind of electric pressure cooking saucepan with above-mentioned heat insulating member, make when the middle ring of this electric pressure cooking saucepan and shell all adopt the high material of pyroconductivity, the heat that can prevent outer pot through in ring conduct to shell, improve the security of electric pressure cooking saucepan.
For solving first technical problem, first technical scheme that the utility model adopts is as follows:
A kind of heat insulating member, it is characterized in that: it comprises multi-section circular arc shape parts, or comprise a circular ring part, the bottom of this arc-shaped part and this circular ring part is used for being located at ring, top is used to support the flange of outer pot, and the bottom is provided with the chimb of downward extension, between the inner ring surface that encircles during this chimb is arranged on and the outer ring surface of outer pot.
Improvement as first technical scheme: the inner ring surface on the inner ring surface of this chimb and heat insulating member top is positioned at same curved surface, makes the inner ring surface of this chimb contact with the outer wall of outer pot.
Improvement as first technical scheme: the inner ring surface of this chimb is provided with the inner ring surface on heat insulating member top is concentric, and the radius of the inner ring surface of chimb is greater than the radius of the inner ring surface on heat insulating member top.
Improvement as first technical scheme: also be provided with some breach on the inner ring surface of this chimb.Because may have bossing on the outer ring surface face of outer pot, for example screw is first-class, so this chimb also need be in response to the default breach of bossing of the outer ring surface of outer pot.
Improvement as first technical scheme: described circular ring part is made up of outer shroud and interior ring, should be provided with outward extending flange by the interior upper limb that encircles, this flange cooperates with the lower surface of the flange of outer pot, the flange of ring below in this outer shroud is set in, and outer shroud size vertically at the axial dimension of flange bottom, makes the lower surface of this outer shroud and the outer ring surface that should interiorly encircle end portion form the step surface that is supported on the middle ring less than ring in this.
Improvement as first technical scheme: the inner ring surface of ring is provided with some breach in described.
For solving second technical problem, second technical scheme that the utility model adopts is as follows:
A kind of have a heat insulating member electric pressure cooking saucepan, comprise shell, outer pot and be arranged on shell and outer pot between connect the middle ring of shell and outer pot; It is characterized in that: this electric pressure cooking saucepan also comprise be arranged in the ring and outer pot between as above-mentioned heat insulating member.
Improvement as second technical scheme: ring is made of metal in described.
Compared with prior art, the beneficial effect of first technical scheme is: when being embedded with this heat insulating member between the middle ring of electric pressure cooking saucepan and the outer pot, the flange of middle ring upper surface and outer pot upper limb is by contacting with upper surface with the lower surface of heat insulating member respectively and in axial direction separating; The inner ring surface of middle ring and the outer ring surface of outer pot are radially separated by the chimb that is arranged on the heat insulating member bottom.Therefore this heat insulating member can play heat-blocking action between middle ring and outer pot, thereby has avoided the outer pot heat directly to conduct to outer pot via middle ring, has improved the security that just has the electric pressure cooking saucepan of this heat insulating member.
Compared with prior art, the beneficial effect of second technical scheme is: owing to be provided with above-mentioned heat insulating member between the middle ring of electric pressure cooking saucepan and outer pot, make the heat of high temperature outer pot conduct to outer pot via middle ring, thereby improved the security of this electric pressure cooking saucepan.

The specific embodiment
First embodiment
Present embodiment is that first technical scheme is described further.
As shown in Figure 1 and Figure 2, present embodiment is the parts 1 of an annular that is made of plastics, and its lower surface 11 is provided with the chimb 2 of downward extension.The outer shroud side 21 of this chimb 2 forms a step surface with the part of this lower surface 11.The inner ring surface 22 of this chimb 2 is positioned at same curved surface with the inner ring surface 12 of this circular ring part 1.Also be provided with some breach 23 that Open Side Down on this chimb 2.
As shown in Figure 3, Figure 4, when user mode, present embodiment is embedded between the middle ring 31 and outer pot 32 of electric pressure cooking saucepan 3.The step surface of this circular ring part 1 bottom props up on the upper surface 311 that is located at middle ring 31; The upper surface 13 of this circular ring part 1 is used for contacting with the flange 321 of outer pot 32; The inner ring surface 12 of this circular ring part 1 contacts with the outer surface 322 of outer pot 32 with the inner ring surface 22 of chimb 2.
Therefore in the axial direction, the distance between the flange 321 of electric pressure cooking saucepan 3 outer pots 32 upper limbs and the upper surface 311 of middle ring 31 is the upper surface 13 of present embodiment and the distance between the lower surface 11; In the radial direction, the distance between the outer surface 322 of the outer pot 32 of electric pressure cooking saucepan 3 and the outer ring surface 312 of middle ring 31 is more than or equal to chimb 2 thickness radially, thereby middle ring 31 is spaced apart with outer pot 32, plays the effect that heat is transmitted that intercepts.
Second embodiment
As Fig. 5, shown in Figure 6, the difference of the present embodiment and first embodiment is: the circular ring part 1 ' of present embodiment is made up of interior ring 15 and outer shroud 16.The upper limb of ring 15 is provided with outward extending flange 151 in being somebody's turn to do, and this flange 151 cooperates (figure slightly) with the lower surface of the flange 321 of outer pot 32.This outer shroud 16 is set in the below of the flange 151 of ring 15 in this, and its height vertically is less than ring 15 height below its flange 151 in this, make this outer shroud 16 lower surface 161 and should in the outer ring surface 152 of ring 15 end portions form one and be used for present embodiment is propped up the step surface that is located on encircling.
