Description

Hinge structure for cooking appliance and cooking appliance

Technical Field

The present utility model relates to a hinge structure for a cooking appliance and a cooking appliance having the same.

Background

Sandwich cooking appliances are commercially available in which contents of toasts, cheeses, eggs, vegetables and the like and sauces are put in order to easily cook sandwiches.

When the upper and lower shells of such a sandwich machine are combined with each other, the contents or sauce is easily pushed to the outside and the whole cannot be uniformly adhered.

In the utility model No. 20-0482291 (design name: sandwick Maker) a structure is disclosed that prevents the leakage of the contents or sauce by forming stepped jaws around the inner circumference and sealing the four edges under pressure.

However, if the distance between the pair of bread is greater than the height of the step formed on the inner circumference, the contents or sauce will be pushed out mainly in the direction of forming the handle, contaminating the sandwich machine itself.

Further, in the coupling process between the upper and lower cases, if the contents or sauce is buried or inserted into the hinge structure formed at the end of the case, cleaning is not easy, resulting in insanitation and inconvenience to the user.

Detailed Description

Hereinafter, exemplary embodiments of the present utility model will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present utility model. This utility model may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, parts irrelevant to the description are omitted for the sake of clarity of explanation of the present utility model.

Throughout the specification, when an element is "connected" with another element, the term has substantially the same meaning as "coupled," fixed, "etc., and a certain component is referred to as" mounted, "in this case, the term has substantially the same meaning as" arranged "and" aligned.

In addition, when a component "comprises" a component, it is meant that other components may be further included, rather than excluded, unless stated otherwise. Also, when a component is referred to as being "between" a component and a component, it includes not only "all components" of the component, but also the distance, space, or area of the component from the component.

The "hinge structure" proposed in the present utility model is a cooking appliance for a sandwich machine or the like, having a hinge shaft for opening and closing the cooking appliance.

Hereinafter, the present utility model will be described in detail with reference to the accompanying drawings.

Fig. 1 is a view showing an opened state of a cooking appliance having a hinge structure according to an embodiment of the present utility model, and fig. 2 is a view showing a coupled state of a cooking appliance having a hinge structure according to an embodiment of the present utility model.

According to one embodiment of the present utility model, the cooking appliance 10 includes a pair of housings and a hinge structure 20 connected to one side to open and close the housings.

The pair of housings and the hinge structure 20 may be formed in a vertically symmetrical structure.

As shown in fig. 1, a pair of housings refers to a lower housing 12a that contacts the ground and an upper housing 12b that is close to the ground.

However, the cooking appliance 10 may be turned by the user during cooking, so the top and bottom of the cooking appliance 10 may be reversed. That is, the upper housing 12b may be in contact with the ground, and the lower housing 12a may be positioned close to the ground, as opposed to that shown in fig. 1.

A pair of bakeware 11a, 11b heated by receiving power may be connected to the insides of the lower and

upper cases

12a and 12b, respectively.

A concave space to which an electric heater (not shown) and grill plates 11a, 11b are mounted may be provided inside the lower housing 12a and the upper housing 12b, and a step is formed around the concave space so that outflow of the cooking object may be minimized.

In the case of products that allow detachment between the bakeware and the housing, safety accidents may occur due to gaps or incomplete connection, and there is also a problem in that the connection structure becomes loose due to long-term use.

Unlike the products allowing the disassembly and assembly between the bakeware and the housing as described above, the pair of bakeware 11a, 11b can be completely fixedly and non-removably coupled to the lower housing 12a and the upper housing 12b.

In addition, the

inner circumferences

outer edges

112a, 112b to the bottom surfaces 113a, 113 b.

For example, the

outer edges

112a, 112b and the bottom surfaces 113a, 113b may be integrally formed as a rectangle, and each corner of the rectangle may be curved.

Since the

inner circumferences

111a, 111b of the bakeware 11a, 11b are formed as slow curved surfaces, a user can put more contents or sauce in during cooking and restrict the leakage of the contents or sauce to the outside.

In addition, during cooking, the contents or sauce may collect in the center of the bakeware and the peripheral portion of the bread is primarily compressed to increase the texture of the sandwiches when the cooking appliance 10 is in the adhesive state.

In addition, the bakeware 11a, 11b may be coated with a fluorine resin, and the coating may prevent a phenomenon in which a cooking object adheres to the bakeware 11a, 11b during cooking.

The hinge structure 20 includes a lower support 21a and an upper support 21b, and the lower support 21a and the upper support 21b are connected by a hinge shaft 22.

The lower support 21a is fixedly connected to one side of the lower housing 12a, and the upper support 21b is fixedly connected to one side of the upper housing 12b.

As shown in fig. 1, the lower support 21a may be fixedly connected at two points at one side of the lower case 12a, but the shape is not particularly limited. The upper support 21b may also be fixedly connected in the same shape as the upper housing 12b.

The connection method may be, for example, using a bolt and a nut, and one end of each support member is engaged and inserted into a previously formed insertion hole in each housing.

The upper support 21b is pivotally connected to the lower support 21a in the up-down direction by a hinge shaft 22, and the upper housing 12b and the lower housing 12a are opened and closed when the upper support 21b pivots in the vertical direction with respect to the lower support 21a about the hinge shaft 22. That is, the lower case 12a and the upper case 12b may be rotated together according to the rotation operation of the lower support 21a and the upper support 21b connected to each other.

In particular, when the cooking appliance 10 contacts the ground in an adhesive state, the lower and

upper supports

21a and 21b respectively include

inclined surfaces

214a and 214b extending obliquely in the up-down direction from the connection portion connected by the hinge shaft 22 and

other end portions

213a and 213b formed from the end portions of the

inclined surfaces

214a and 214 b. In addition, in the above case, when the cooking appliance 10 is opened, the lower support 21a and the upper support 21b are contacted by the

inclined surfaces

214a, 214b, limiting the maximum rotation angle of the upper housing 12b, and on the other hand, when the cooking appliance 10 is vertically placed with respect to the ground in a coupled state, the other ends 213a, 213b are contacted with the ground to support the cooking appliance 10.

In addition, the hinge shaft 22 of the hinge structure 20 connects the lower support 21a and the upper support 21b at a position spaced apart from a fixed coupling portion between the lower support 21a and the lower housing 12a by a predetermined distance d in an outer direction.

In this case, the predetermined distance d may be determined based on at least one of the weight and the size of the lower housing 12a and the weight and the size of the upper housing 12b.

For example, the heavier the housing the shorter the predetermined distance d, the larger the housing the shorter the predetermined distance d.

In this way, the hinge shaft 22 is mounted on the hinge structure 20 to be separated from the lower housing 12a and the upper housing 12b by a predetermined distance d, so that the phenomenon that the contents or sauce is discharged to the outside of the bakeware 11a, 11b is minimized when the two housings are coupled together. In addition, when the two housings are coupled to each other, it is helpful to uniformly compress the whole cooking object, and the possibility that the contents or sauce is buried or inserted into the hinge shaft 22 can be reduced.

Further, at least one of the lower and

upper supports

21a and 21b may support the cooking appliance 10 in an opened or coupled state of the lower and

upper housings

12a and 12b.

The lower support 21a may support a protrusion 114 (refer to fig. 3) formed at the outside of the lower case 12a and the cooking appliance 10 when the cooking appliance 10 is in an opened or coupled state.

When the cooking appliance 10 is in the coupled state and the stand is erected on the ground, the lower support 21a and the upper support 21b can simultaneously support the cooking appliance 10, and as shown in fig. 3, a user stands the cooking appliance 10 to store. At this time, the power cord 16 may be wound around the lower support 21a and the upper support 21b.

Meanwhile, a lower handle 13a is integrally formed at the other side of the lower housing 12a, and an upper handle 13b is integrally formed at the other side of the upper housing 12b. When the two housings are coupled to each other, the lower handle 13a and the upper handle 13b are in contact with each other, and thus can be used as one handle.

A locking protrusion 131a is formed on an upper surface of the lower handle 13a, and a locking ring 131b is formed on an upper surface of the upper handle 13b so as to be rotatable in a vertical direction.

When the cooking appliance 10 is in the coupled state, the locking ring 131b is coupled to the locking protrusion 131a as being rotated downward, so that the cooking appliance 10 is prevented from being opened.

The locking protrusion 131a and the locking ring 131b are not particularly limited to those shown in fig. 1, and may be modified by other known coupling means.

As shown in fig. 1,

wire holes

14a, 14b may be formed on one side of the lower and

upper cases

12a, 12b, and wires may be connected to each of the electric heaters disposed in the lower and

upper cases

12a, 12b, and inserted into the

wire holes

14a, 14 b.

In addition, as shown in fig. 1, a power hole 15 may be formed in parallel with the wire hole 14b at one side of the upper case 12b, and a power wire 16 may be inserted into the power hole 15, and the corresponding power wire 16 may supply power to the electric heater to heat the bakeware 11a, 11b.

In addition, two

indication lamps

115, 116 are formed on the outer surface of the lower case 12a, one of which serves as an indication lamp 115 indicating on/off of the power supply and the other of which can serve as an indication lamp 115 indicating whether or not it is heated to a temperature suitable for cooking. The power supply may perform power on/off by a button (not shown) formed on one side of the housing.

Hereinafter, the detailed structure of the hinge structure 20 for the cooking appliance 10 will be described in more detail.

Fig. 2 is a view illustrating a side surface of a hinge structure when a cooking appliance according to some embodiments of the present utility model is in an open state and in a coupled state.

The hinge structure 20 includes a lower support 21a fixedly connected to one side of the lower housing 12a and an upper support 21b fixedly connected to one side of the upper housing 12b.

The upper support 21b is coupled to the lower support 21a in the up-down direction by a hinge shaft 22, and the upper housing 12b and the lower housing 12a are opened and closed when the upper support 21b rotates in the vertical direction with respect to the lower support 21a about the hinge shaft 22.

At this time, the hinge shaft 22 connects the lower support 21a and the upper support 21b at a position spaced apart from a fixed connection position between the lower support 21a and the lower housing 12a by a predetermined distance d in an outward direction.

Specifically, the lower support 21a is included to have one end 211a fixedly connected to one side of the lower housing 12a, a middle end 212a connected by the upper support 21b and the hinge shaft 22, and the other end 213a extending in a downward direction from the connection portion through the hinge shaft 22.

As shown on the right side of fig. 2, when the cooking appliance 10 is in the coupled state, the upper support 21b has one end 211b fixedly connected to one side of the upper housing 12b, a middle end 212b connected to the lower support 21a through the hinge shaft 22, and the other end 213a extending from the connection portion opposite to the extending direction of the other end 213a of the lower support 21a through the hinge shaft 22.

That is, the other ends 213a, 213b are formed by bending downward and upward from the end portions of the

inclined surfaces

214a, 214b, respectively.

As shown in fig. 2, when the cooking appliance 10 is in a coupled state and the lower and

upper cases

12a and 12b are perpendicular to the ground, the other end 213a of the lower support 21a and the other end 213b of the upper support 21b can simultaneously support the cooking appliance 10.

As shown on the right side of fig. 2, the length f between the tip of the other end 213a of the lower support 21a and the tip of the other end 213b of the upper support 21b is longer than the length e between the lower face of the one end 211a of the lower support 21a and the upper face of the one end 211b of the upper support 21b.

Such a structure and shape provides a space in which the power cord 16 is wound between the other ends 213a, 213b of the two supports and the two

housings

12a, 12b when the cooking appliance 10 is erected and stored as shown in fig. 3.

In addition, the middle portion 212a of the lower support 21a may have an inclined surface 214a inclined toward the other end 213a of the lower support 21a at a connection portion through the hinge shaft 22.

At this time, as shown in the left side of fig. 2, when the cooking appliance 10 is opened, the inclined surface 214a contacts with a portion of the upper support 21b or the inclined surface 214b, so that the maximum rotation angle of the upper support 21b can be limited.

Preferably, the maximum rotation angle is 95 to 100 degrees. If it is less than 95 degrees, the upper case 12b and the upper support 21b of the cooking appliance 10 in the opened state may be rotated downward, resulting in a safety accident, and if it is more than 100 degrees, the cooking appliance 10 falls down rearward due to the own weight of the upper case 12b and the upper support 21b.

With the hinge structure and the cooking appliance having the hinge structure described so far, a user can cook various foods, and the problem that contents are pushed out or sauce flows out during the process of changing from the opened state to the bonded state can be minimized.

In describing an exemplary cooking method, a user prefers to cook eggs and vegetables in an open state. Thereafter, the user covers the face cover on one side of the cooking contents and adheres the cooking appliance. The user then rotates the cooking appliance in the coupled state by 180 degrees. The user then opens the cooking appliance and covers the other side of the cooked contents with a face.

In this way, cooking can be performed using the baking tray not only in the coupled state but also in the opened state, and thus a separate frying pan is not required.

The foregoing description of the utility model has been provided for illustrative purposes only, and those skilled in the art to which the utility model pertains can easily be transformed into other specific forms without changing the technical spirit or essential features of the utility model. The above embodiments are therefore to be understood as illustrative in all respects and not restrictive. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as distributed may also be implemented in combination.

The scope of the utility model is indicated by the following claims rather than by the detailed description, and all changes or modifications that come within the meaning and range of equivalency of the claims are intended to be embraced therein.
