Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an oven safety lock device for a multi-

The present invention relates to a safety device for a multi-functional food maker including a rotary blade such as a food processor or a multi-cooker, and more particularly, to a multi-purpose food maker for safer and more convenient locking and unlocking of an oven covering a sharp rotary blade To an oven safety lock device.

Generally, a multipurpose food maker, which is referred to as a food processor or a multi-cooker, is used to encompass both porridge cooker, baby food maker, and blender. Conventional general food manufacturing machines incorporate one or more contents for food production in a main body, put water and various condiments therein, and heat them to cook foods.

Various examples of conventional multipurpose food preparation machines are described below.

According to Japanese Patent Registration No. 3651685 (registered on Mar. 4, 2005, with reference to FIG. 1A), crushing means for crushing various kinds of grains and various vegetables such as rice, which is a raw material of porridge, Is provided integrally with the dish so that the dish can be cooked conveniently in a shorter time.

In the constitution of such a domestic porridge cooker, a predetermined amount of water and porridge raw materials are injected and the upper side is formed into a columnar shape with an open top, and a container handle 306 for movement is installed on one side, A container part 300 in which the device 308 is installed; A hook support bracket 118 is formed at a position corresponding to the hook device 308 at both outer ends of the hook support bracket 118, A motor 125 having a crushing blade 127 is installed at an end of the rotary shaft 126 so as to be inserted into the inside of the crushing blade 127. A heater 122 for heating water is installed outside the crushing blade 127, And a driving unit 100 having a control unit 113 for controlling the motor and the heater.

1A is configured such that the driving unit 100 having the heater 122 and the crushing blade 127 is inserted and mounted from the upper part of the container unit 300. The container unit 300, The cookware is directly fed into the cooking cavity and cooked using the heater 122 and the crushing blade 127. The hook device 308 of the container portion 300 and the hook- Thereby locking the oven main body.

However, since the operation of the hook device is constituted by the hinge operation structure, when the oven main body is to be unlocked, it is necessary to accurately press the end portion of the hook device, not the hinge portion, So that convenience is deteriorated. Accordingly, there is an urgent need to develop an oven unlocking structure that can be smoothly operated up and down by pushing the entire button to improve user convenience and operability.

According to Japanese Patent Registration No. 4009651 (registered on Jul. 7, 2007, see Fig. 1B), the function of finely grinding food ingredients, the function of boiling or grinding crushed food ingredients, and the filtration function, There is provided a liquid food cooker in which a series of operations for separating food waste is carried out by an extraction container and a pressure vessel of a two-layer structure.

Such a liquid food cooker is capable of easily cooking soybean oil or various soups in the home by using the principle of siphoning using pressure and decompression generated by heating the pressure vessel, The pressure vessel 4 and the extraction vessel 5 are detachably attached to the main body (stand 1) together with the vessel 4 and the extraction vessel 5 mounted on the pressure vessel 4. [

The liquid food cooker of Fig. 1B having such a structure can be installed detachably to the main body (stand 1) by rotating the handle of the extraction container 5 mounted on the pressure vessel 4 corresponding to the oven main body and the lid cover In this case, the rotation of the lid or the container may be difficult due to the packing frictional force during the rotation process.

The object of the present invention is to provide an oven lock safety device for a multi-purpose food manufacturing machine which is developed to solve the above-described problems and which can substantially more securely and smoothly lock and unlock the oven in which food is manufactured .

The oven lock safety device developed in accordance with the above-described problems is for preventing the oven from being disengaged arbitrarily during operation of a multi-functional food manufacturing machine including a rotary knife. The oven lock safety device includes a handle A housing having a top portion corresponding to the handle surface and having a planar structure and extending downward along an oblique surface of the oven from the top portion and being tightly coupled to a side surface of the oven; A push button that a part of the push button is pulled out of the housing through the slit so as to enable an upward pushing operation through a slit formed in a top flat portion of the housing; And a hook member which rotates forward and backward so as to be engaged with or disengaged from the oven mounting portion of the food maker in conjunction with the pushing operation of the push button, wherein the hook member has a flat structure such that one side thereof is in close contact with the upper surface of the push button And the other side of which is bent or bent at least once from the plane so as to extend downward along the inner wall surface of the housing, and a connection hole connected to the push button is formed at the upper end of the hook member, And a hook is formed at the lower end of the hook for hooking or releasing the oven mounting portion in the food maker by the shaft rotation.

According to the present invention, a spring is mounted between the top surface of the push button and the bottom surface of the handle, and one or more guide protrusions for guiding the pressing operation of the push button are formed on the upper flat surface of the housing, And a guide hole in which the projection is inserted is formed.

According to the present invention, the hook member is provided with one or more hinge projections on both the left and right sides, and the hinge protrusion formed at one end of the hook member among the hinge protrusions is hinged to the link portion formed at the upper end of the push button, The hinge protrusion formed at the other end of the member is hinged to the hinge groove of the housing, and the arm portion has a gentle curved structure in a direction opposite to the bending direction of the plane, and rotates about the hinge protrusion.

From the above-described configuration, the present invention can more smoothly and safely perform the locking and unlocking of the oven covering the blade portion in the food maker including the rotary blade.
