Detailed Description

The electric fryer 1 shown in the figure comprises: a container 2 capable of receiving a cooking bath, and a base 4 arranged below the lower portion 2a of the container 2. The deep fryer 1 comprises electric heating means 3 associated with the receptacle 2.

The container 2 is made of metal. The container 2 may in particular be made of aluminium. The container 2 may include an inner coating and/or an outer coating, if desired. The inner coating and/or the outer coating may be partial.

The base 4 can be made of plastic, in particular plastic that does not continuously withstand the temperatures reached by the lower portion 2a of the container 2 when the deep fryer 1 is in use. Thus, the base 4 may be made of PP (polypropylene).

The container 2 is assembled with a base 4 to form a chamber 5 housing at least a part of the electric heating device 3. In the embodiment shown in the figures, the chamber 5 houses the electric heating means 3. As can be seen in fig. 3, the lower part of the base 4 has an aperture 8. Preferably, the holes 8 are lateral and are arranged in recesses of the lower part of the base 4, so as to avoid direct access to the electrical and heating portions of the electrical heating device 3 housed inside the chamber 5. The electric heating device 3 is fixed under the lower portion 2a of the container 2. Thus, the electric heating means 3 extend below the lower portion 2a of the container 2. More specifically, in the embodiment shown in the figures, the electric heating means 3 are made in the form of a shielded heating element. The chamber 5 also houses the electrical connections of the electrical heating means 3. The chamber 5 may also house temperature control devices and thermal safety devices. The temperature control device is, for example, a thermostat. The thermal safety device is, for example, a thermal fuse or a resettable thermal limiter. As a variant, the electric heating means 3 may extend in particular partially inside the container 2, or may also be arranged in the chamber 5 without having to be fixed below the lower portion 2a of the container 2.

A plurality of uprights 6 emerge from the lower portion 2a of the container 2. The upright 6 is assembled with the bottom of the container 2, for example by welding. The retaining element 7 engages with the upright 6 to retain the base 4. Each retaining element 7 is mounted on one of the uprights 6. The chamber 5 is traversed by a pillar 6.

More specifically, in the embodiment shown in the figures, each upright 6 is formed by a rod 6 a. Each rod 6a has a threaded portion 6 b. Each retaining element 7 forms a nut 7a screwed onto one of the threaded portions 6b, as can be seen in fig. 4.

The deep fryer 1 comprises an upper thermal insulation means 10 interposed between the base 4 and the lower portion 2a of the container 2. The upper thermal insulation means 10 is made of a thermal insulating material which continuously withstands the temperature reached by the lower portion 2a of the container 2 when the deep fryer 1 is in use.

In the embodiment shown in the figures, the upper thermal insulation means 10 extends annularly between the base 4 and the container 2. The upper thermal insulation means 10 comprise a ring 11 interposed between the base 4 and the container 2. The ring 11 is preferably centered on the base 4, with a portion of the ring 11 surrounding a portion of the base 4. The ring 11 may be clamped to the base 4 if desired. For this purpose, the ring 11 has lateral hooks 13, these lateral hooks 13 being arranged to engage in retaining receptacles 41 arranged in the base plate 4.

The ring 11 is made of plastic which is continuously resistant to the temperatures reached by the lower portion 2a of the receptacle 2 when the deep fryer 1 is in use. The ring 11 can be made in particular of PPS (polyphenylene sulfide), or of PA (polyamide), or of PBT (polybutylene terephthalate), or of PET (polyethylene terephthalate), or of a thermosetting plastic, if desired of bakelite or silicone.

More specifically, in the embodiment shown in the figures, the upper thermal insulation means 10 comprise an annular gasket 12. An annular gasket 12 is carried by the ring 11. An annular gasket 12 is mounted around the lower portion 2a of the container 2. The annular gasket 12 is therefore centred with respect to the container 2. The annular gasket 12 is compressed by the container 2 assembled with the base 4.

The deep fryer 1 comprises a lower thermal insulation means 20 interposed between the base 4 and each upright 6. Each lower thermal insulation means 20 is made of a thermal insulating material which continuously withstands the temperature reached by the upright 6 when the deep fryer 1 is in use, said lower thermal insulation means 20 being mounted on the upright 6.

In the embodiment shown in fig. 1 to 4, the lower thermal insulation means 20 is formed by the retaining element 7. Thus, the lower insulation 20 is tubular. The lower insulation means 20 is made of PPS, or supported PA, or supported PBT, or PET, for example. The lower thermal insulation means 20 has a flange 20b, which flange 20b is supported on the outer wall of the bottom of the base 4. As can be seen in fig. 3 and 4, the lower thermal insulation means 20 is mounted in a recess 9 arranged in the outer wall of the bottom of the base 4.

The variant of embodiment illustrated in fig. 5 differs from the one illustrated in fig. 1 to 4 in that the lower thermal insulation means 20 ' interposed between the base 4 and each upright 6 are retained by retaining elements 7 ', the retaining elements 7 ' engaging with the uprights 6 to retain the base 4. The lower insulation 20' is made of PPS, or supported PA, or supported PBT, or PET, for example. The lower insulation 20' is tubular. Each lower thermal insulation means 20' is mounted around one of the uprights 6. Each retaining element 7 'forms a nut 7' a, the nut 7 'a being screwed onto one of the threaded portions 6b of the upright 6 and bearing on one of the lower thermal insulation means 20'. Preferably, the lower thermal insulation means 20' is made in a single piece. As can be seen in fig. 5, each lower thermal insulation means 20' is mounted in a recess 9 arranged in the outer wall of the bottom of the base 4. Each lower thermal insulation means 20 ' has a flange 20 ' b, which flange 20 ' b bears on the outer wall of the bottom of the base 4. Preferably, each lower thermal insulation means 20 ' comprises a portion 20 ' a surrounding the respective retaining element 7 '.

The deep fryer 1 shown in the figures operates and is used in the following manner.

When the cooking bath contained in the container 2 is heated by the electric heating means 3 to prepare fried food, the temperature of the lower portion 2a of the container 2 reaches at least 150 ℃. The upper and lower thermal insulation means 10, 20 allow to limit the propagation of heat from the lower portion 2a of the container 2 towards the base 4. Thus, the temperature reached by the base 4 can be limited, which allows reducing the risk of burns to the user and the risk of damage to the support on which the base 4 rests. Thus, the base 4 can be made of plastic at low cost, while ensuring a firm assembly between the base 4 and the container 2.

As a variant, the chamber 5 can be traversed by at least one upright 6 coming out from the lower portion 2a of the container 2. If the chamber 5 is traversed by a single upright 6, the retaining element 7; 7' engage with the upright 6 to hold the base 4, and the lower thermal insulation means 20; 20' are interposed between the base 4 and the upright 6. If the chamber 5 is traversed by a plurality of uprights 6, the retaining element 7; 7' engage with each upright 6 to retain the base 4. Preferably, each upright 6 is associated with a retaining element 7; 7' are associated. However, the same retaining element 7; 7' may engage with a plurality of uprights 6. Preferably, each upright 6 is connected to a lower thermal insulation means 20; 20' are associated. However, the same lower thermal insulation means 20; 20' may be interposed between the base 4 and the plurality of uprights 6.

As a variant, the upper thermal insulation means 10 need not comprise an annular gasket 12. The container 2 can rest, in particular, directly on the ring 11, if desired.

The invention is in no way limited to the described embodiments and variants thereof, but comprises many modifications within the scope of the claims.
