In describing the electric heat cooker (A) having hot air conveying means according to the present invention, a non-strict approximate direction reference is specified for convenience in reference to FIGS. 1 and 2.

The top, bottom, left and right are divided in the state as shown, and in the detailed description and claims of the invention related to the other drawings, the direction is specified in accordance with this criterion.

First, as shown schematically in Figs. 1, 3 and 4, the electric heat cooker (A) having a hot air conveying means in the present invention is a housing 10, a heat source (H) built in the housing, a heat source The conveying means P for conveying the heated air downward, the accommodating means 20 accommodating the object to be cooked, the support 30 accommodating and supporting the accommodating means, and below the lower vent 27 of the accommodating means 20. It comprises a hot air conveying means 40 arranged to be spaced apart to reflect the hot air to the upper side to cause convection, that is, cavitation.

In the conventional convection oven, a propeller, that is, the convection module is provided at the rear or side of the oven, the electric heat cooker (A) having a hot air conveying means according to the present invention is provided with a convection module at the top and hot air from the top to the bottom. The first feature is that convection is generated during the first transfer.

From this it is possible to improve the structure of a conventional convection oven and achieve miniaturization of the oven, and to enable a small amount of cooking suitable for households of one or two.

In addition, the lower accommodating portion 11 (see FIG. 1) of the housing 10 is built in the lead body D so that the accommodating means 20 can be drawn out, and is opened in one side, that is, the drawer type is opened to the right side, and accommodated. Convenience is increased by allowing the means 20 itself and the cooking object C to be added or separated.

The take-out body (D) having a handle (Da) is preferably a structure that is completely separated from the main body, various locking means for preventing any separation in the cooking process, safety means such as kids lock, or simply handle (Da) It is preferable to have a safety means to be unlocked and separated by operating a button or a lever separately, not by sliding separation by the pulling operation.

The heat source H provided in the upper part of the housing 10 may be a conventional metal (especially stainless metal) heater, but is preferably composed of various alternative heaters such as a lamp heater to secure fast cooking characteristics by shortening the preheating time. In the drawings, halogen heaters are illustrated.

In addition, when the heat source (H) is a lamp type heater, due to miniaturization, in order to prevent the light of the lamp from being concentrated on the upper part of the cooking object (C) at a close position, the light alleviating member (Ha) to the lower part of the lamp type heater is shielded. It is preferable that a member is provided, such a relaxation member (Ha) may be, for example, a mesh member, as shown in the right one-dot chain line circle of FIG. 1.

Next, the convection module, ie, the conveying means P, which transfers heated air to generate heat convection, is composed of a propeller Pa and a motor Pb for rotation thereof.

If necessary, the propeller Pa may be provided at a lower portion of the heat source H or arranged at another position. When the propeller is provided at the lower portion of the heat source, the propeller serves as a transfer means and a light mitigating member.

[Combination of the leading body (D) -supporting body 30-storage means 20] is the exposure or storage in the housing or seating is made by sliding the handle Da,

The support body 30 with respect to the lead body (D) is preferably configured in a form that is easily separated without operating a special means,

In addition, the receiving means 20 with respect to the support 30 is also preferably configured in a form that is easily separated.

The support body 30 incorporated in the lead body D has upper and lower seating portions 31 and 33, and has an open top portion.

The accommodating means 20 accommodated in the paper body 30 has an opening 21 in the upper portion thereof, which enables the input of the cooking object C, and an aeration portion 27 is provided in the lower portion thereof to generate oil when cooking. In addition, the debris falls to the lower part, and the hot air passes through the vent and is returned to the upper part by the hot air conveying means 40 provided at the lower part so that convection is generated.

For ease of cleaning, the vent part 27 is composed of a mesh member, and is disposed in the support flange 23a formed inwardly bent at the lower end of the outer wall of the receiving means 20. When the mesh member constituting the vent part 27 is separated, the lower opening 23 of the accommodation means 20 can be confirmed.

The upper support flange 21a, which is bent outwardly on the top of the outer wall 25, is coupled to the upper seating portion 31 of the support 30, and a spaced portion is formed under the mesh member, which is an air vent 27.

Next, it is preferable that the hot air conveying means 40 is an impeller member 41. The impeller member preferably has a spiral wing to form a vortex in the hot air supplied downward.

Further, the impeller member 41 is free of contamination problems even when the debris, oil, etc. of the cooking object fall on the conveying means 40 provided under the cooking object C receiving means 20. It is preferable that the plate-like support panel 41A and the spiral blade 41B protrude integrally with the base panel.

Furthermore, it is preferable that the hot air conveyance means 40 is pivoted by the rotation means 45 including the motor 45B so that the convection efficiency can be further improved.

To this end, the impeller member 41 arranged on the lower surface mounting portion 33 of the support 30 is connected through the motor 45B and the shaft member 45A of the rotation means 45.

In particular, when the motor 45B is arranged outside the bottom of the support 30, the support 30 has a hollow 35 (see FIG. 4) formed at the center of the bottom surface thereof.

The impeller member 41 has a snow projection 43 at the center lower portion of the support panel 41A, and this snow projection can be connected to the motor 45B on the outside by passing through the hollow 35 of the support.

More specifically, in consideration of the characteristics of the impeller member 41 to be separated and coupled with the support body 30 detachable from time to time with the lead body (D),

The shaft member 45A connected to the motor 45B under the support body 30 may be provided with a reduction gear for improving torque, and a reduction gear integrated commercial motor module may be used, if necessary. As shown in the dashed-dotted circle, it has a horizontal straight male member 45a,

The accumulating protrusion 43 of the impeller member 41 exposed through the hollow 35 of the support 30 has a female member 43A coupled to the male member 45a.

In particular, in order to allow the male and female members 43A and 45a to be naturally coupled in the process of operating the motor 45B without precisely and carefully coupling the male and female members 43A and 45a.

Both side protrusions forming the straight arm member 43A corresponding to the male member respectively have a coupling guide portion 43a having an inclined shape so as to be gradually lowered based on the highest separation preventing portion 43b at the center. (The difference between the 'height' and 'engagement guide' relative 'height' can be described as 'high', 'low' when the impeller is turned upside down, the above description is based on the state in which the impeller is turned upside down Will be explained).

When the separated work feller member 41 is coupled to the support body 30, the snow-crusting protrusion 43 is coupled to the hollow 35 of the support body and exposed to the lower portion, and the lead body D to which the support body 30 is coupled is exposed. Coupled to the housing 10, the receiving portion 11,

When the electrothermal cooker A is operated (or separately operated when the motor 45B (the hot wind reflecting means 40) is operated), the shaft member 45A is rotated in accordance with the rotation of the motor, and the straight male member 45a is rotated. Momentary projection 43 of the impeller member coincides with the arm member 43A at the moment (early), and naturally slides while meeting the round type engagement guide portion 43a outside the central escape prevention portion 43b. 45a can be combined with each other,

Once combined, the relatively high separation prevention portion 43b and the inner wall of the separation prevention portion form a '()' shape to prevent random separation due to the arm member 43A having a wide middle and a narrow shape below.

In addition, the shape of the male member 45a together with the characteristics of the round-type coupling guide portion 43a and the separation prevention portion 43b also has a narrow upper end portion, so that the male and female members can be easily coupled at one time.

Next, as can be seen in Figure 2 showing a modification,

In the electric heat cooker (A) having hot air conveying means, the upper portion of the accommodating means (20) is further provided with a guide means (50) for guiding a part of the hot air to the outer bottom of the outer wall (25) of the accommodating means (20).

The main hot air convection (W) is not only directly supplied into the receiving means 20, but also forms an outward hot air convection (W1) upward through the lower opening 23 through the receiving means outer wall 25 to further increase the convection efficiency. It is possible to obtain the effect of improving thermal efficiency, cooking time, and maturity characteristics.

In FIG. 2, the guide means 50 is composed of a ring member 50r corresponding to the main body and a fixing member, in particular a fixing piece 55, which fixes the ring member inside the housing.

As for the cross section of the ring member 50r, the inclination part 51 and the vertical part 53 are formed continuously,

As shown in a perspective view in the lower one-dot chain line circle of Figure 2, the deformable storage means (20m), the upper support flange is formed by separating the support leg (21m), between the support leg is formed with a hot air passage (21p) ,

In the vertical portion 53 of the ring member 50r, the deformation-receiving means 20m is arranged at an upper end of the outer wall 25 or is arranged outside.

(I.e., the outer diameter of the storage means 20m and the outer diameter of the vertical portion 53 of the ring member 50r are the same or the outer diameter of the vertical portion 53 is greater).

Part of the hot air is separated from the main hot air convection (W) without disturbing convection naturally by the round type upper inclined portion (51) of the ring member (50r) to form an outward hot air convection (W1)

After passing through the upper passage portion 21p of the storage means 20m and passing through the gap between the outer wall 25 of the storage means and the inner wall of the support 20,

Upflow is formed through the lower opening 23 of the receiving means, that is, the mesh member type vent 27.

This improves cooking efficiency.

In addition, as shown in another modified example with a coupling sectional view in the right one-dot chain line in Fig. 3, if necessary, the support also forms a modified support 30m,

Impeller members 41 are finely spaced and arranged outside the seating portion 33m below the support 30m.

(Basic support 30 seating portion 33 and the impeller member 41 likewise forms a finely spaced tolerance),

In the case of the basic type of FIG. 1, foreign substances such as oil are introduced into the gap between the support 30 and the impeller member 41 arranged inside, and as a result, there is a risk of contaminating the rotation means 45 and the like.

The deformable support 30m and the impeller member 41 may further enhance the electric cooker failure prevention characteristics such as cleanliness and rotation means.

If necessary, the impeller member 41 may further introduce appropriate friction reducing means such as bearings to prevent frictional resistance and noise caused by rotation.

In the above description of the present invention with reference to the accompanying drawings, a heat cooker having a hot air conveying means having a specific shape and structure has been described mainly with the present invention various modifications, changes and substitutions by those skilled in the art, such modifications , Changes and substitutions should be construed as falling within the protection scope of the present invention.
