The oven range is a free standing type in which the side cover 230 is exposed to the outside, which is installed independently of the kitchen furniture 10, and the side covers 230 at both sides of the oven range are provided with the kitchen furniture ( 10) It can be divided into a built-in type built in between. For example, in the built-in oven range, the installation of the side cover 230 may be omitted. When the side cover 230 is not provided, heat is accumulated in the empty space formed by the side of the cavity 210 and the kitchen furniture 10, and the heat is discharged to the outside by the duct unit of the present invention.

The oven range of the present invention is a hybrid type that can be used as two types of built-in type or free standing type depending on whether or not it is embedded in the kitchen furniture 10 indicated by the virtual line of FIG. 1.

The oven range includes an oven unit 200 which indirectly heats food by convection heat transfer for confectionery, bakery, and barbecue cooking, and a cooktop unit 100 which is provided on the upper side of the oven unit 200 and directly heats a cooking utensil. .

As a heat source which heats the oven part 200, an electric heater, a microwave, a gas flame, etc. are mentioned. The oven unit 200 includes a cavity 210, a door 212, and a side cover 230. In this case, an upper panel 220 covering the upper side of the cavity 210 may be further provided.

The cavity 210, which is a food cooking space, is opened and closed by a door 212, and a rack 216 on which food is placed is installed in the cavity 210. The interior of the cavity 210 is preferably coated with enamel or other enamel to facilitate cleaning. The rack 216 is movably supported in the direction of the door 212 along the guide member 215 formed inside the cavity 210. By taking out the rack 216, food is introduced into the cavity 210, or the cooked food is taken out. Side cover 230 is to form the exterior of the oven range. When the insulation 240 is interposed between the side cover 230 and the cavity 210, heat of the cavity 210 is blocked from being transferred to the surroundings. As a more aggressive overheating prevention measure, it is preferable to provide the duct unit of the present invention to prevent overheating.

The heating element 110 is provided on the upper surface of the cooktop 100 to heat the cooking utensils. Any kind of heat generator 110 may be a gas burner, an electric heater, a far infrared heater, or a microwave.

The cooktop unit 100 is provided with a controller 120 for displaying a user menu and controlling the overall operation of the oven range. The controller 120 may detect the temperature inside the cavity 210 and the degree of ripening of the food, and control the oven unit 200 so that the food does not burn, and display various menus and operation states so that the user can select a desired menu. The controller may perform various control functions such as a remaining heat display function for displaying the remaining heat, a reservation function, a timer function, and a self-clean function for automatically cleaning the inside of the cavity 210. The controller 120 is provided in the form of a PCB on which a microprocessor is mounted.

On the other hand, if heat is concentrated in a specific part of the oven range, the controller 120, which is particularly sensitive to static electricity or heat, may malfunction or be damaged. In particular, since the cavity 210 is elevated to a high temperature when performing a self clean mode that burns dirt or odors inside the cavity 210 at high temperatures, the heat concentration phenomenon is prominent. In addition, when the microwave oven is installed in a built-in type, the oven is installed in an enclosed space of the kitchen furniture 10, resulting in poor cooling efficiency, causing hot spots in the oven range, or the kitchen furniture 10 around the oven. May for example be overheated above 90 ° C.

This overheating phenomenon can be suppressed by wrapping the upper and side surfaces of the cavity 210 with the heat insulator 240. The present invention is not limited thereto, and the present invention includes a duct unit as a means for more actively blocking heat transmitted to the side cover 230 or the controller 120 adjacent to the kitchen furniture 10.

In particular, since the oven range of the present invention is a hybrid type that can also serve as a free standing type and a built-in type, it is preferable that the controller 120 is provided on the upper side of the oven unit 200 and the front of the cooktop unit 100. Therefore, the duct unit has a structure capable of intensively circulating air in this portion so that heat is not concentrated on the upper surface of the upper portion of the oven unit 200, which is the position where the controller 120 is provided. Hereinafter, the front direction is a direction toward the door 212 and the rear direction is defined as a direction toward the rear wall inside the cavity 210.

Meanwhile, when the oven range of the present invention is installed as a free standing type, the air around the oven unit 200 may be circulated by natural convection through an empty space between the side cover 230 and the oven unit 200. However, when the oven range of the present invention is installed in a built-in type, such natural convection does not provide sufficient overheat protection. Therefore, since the controller 120 or the side cover 230 are easily overheated, the cooling fan 250 and the duct unit are provided as in the present invention, thereby forcibly circulating air to prevent overheating.

Referring to the temperature distribution picture shown in Figure 2, the portion of high temperature is shown in red. When the duct unit of the present invention is not provided, hot spots are formed in red on the upper front surface of the oven unit 200. Heat is concentrated on the upper side of the oven unit 200 due to the heat of the cavity 210, and in particular, heat is further concentrated on the entire upper surface of the oven unit 200. This is because the air circulation around the cavity 210 is not smooth at the upper side of the oven unit 200, particularly at the upper front side of the oven unit 200. The temperature of the upper side of the oven unit 200 is higher due to the rise of hot air, and there is an empty space in which the air flows to the rear of the oven unit 200, while the door unit 212 is located in the oven unit 200. This may be due to the formation of less empty space on the front for air flow.

1, 3, and 4, the duct unit includes an intake duct 270, an exhaust duct 260, and a cooling fan 250. Here, it is preferable that the duct unit further includes a front slot 130 and an upper slot 223.

Hot air heated by the cavity 210 is accumulated in the empty space 310 formed between the side surface of the cavity 210 and the side cover 230. In the case where the insulation 240 is interposed on the side of the cavity 210, heat is accumulated in an empty space between the insulation 240 and the side cover 230.

This heat is discharged to the outside by the duct unit. The duct unit sucks heat accumulated in the inner space of the side cover 230 and discharges it to the outside of the oven unit 200 to suppress the occurrence of hot spots on the upper front side of the side cover 230 and to install the oven in a built-in type kitchen. Prevent the temperature rise of the furniture 10.

The intake duct 270 sucks heat accumulated in the side space of the cavity 210 and the internal space formed by the side cover 230, and is located on the upper surface of the exhaust duct 260 and the front surface of the intake duct 270 ( 272 preferably has a sufficient width to wrap top slot 223.

The exhaust duct 260 is located above the cavity 210 as a moving passage of air connecting the cooling fan 250 and the front slot 130. When the top panel 220 is provided on the upper side of the cavity 210 and the heat insulating material 240 is interposed between the upper side and the upper panel 220 of the cavity 210, the exhaust duct 260 is placed on the upper panel 220. Located. The exhaust duct 260 discharges heat inside the side cover 230 introduced through the rear surface 273 of the intake duct 270 to the outside of the oven unit 200 through the front slot 130.

The front slot 130 is an air flow passage formed above the door 212, and communicates with the front surface 262 of the exhaust duct 260 to discharge heat to the outside.

The upper slot 223 serves as a passage through which the heat of the inner space of the side cover 230 is drawn out to the intake duct 270 and is provided at both edges of the upper panel 220 covering the upper side of the cavity 210. Since the flow of air needs to be concentrated in this portion in order to centrally cool the controller 120 and the upper surface of the oven unit 200 where the hot spots are located, the upper slot 223 is locally located at the front of both edges of the upper panel 220. It is preferable to be provided with.

Although not shown, when the upper slot 223 is formed over the entire length of both edges of the upper panel 220, the upper slot 223 positioned in front of the oven unit 200 among the upper slots 223. Design the shape, length and width of the intake duct 270 so as to cover. Therefore, the flow of air is concentrated on the upper surface of the upper side of the side cover 230 to prevent hot spots and overheating of the controller 120.

That is, regardless of whether the top slot 223 is formed over a part of both edges of the top panel 220 or the entirety of both edges of the top panel 220, the total length d of the depth direction of the oven unit 200 may be determined. It is preferable that the intake of the intake duct 270 is made through the upper surface slot 223 disposed on the front side of the oven unit 200 from the half point.

The cooling fan 250 is disposed on the rear surface of the intake duct 270 and rotates to generate air flow force. The cooling fan 250 and the rear surface of the intake duct 270 are connected by the cooling fan hole 253.

Although not shown, the controller 120 senses heat concentration around the oven unit 200 through a temperature sensor provided in the side cover 230, the inside of the cavity 210, the upper side of the cavity 210, and the cooling fan 250. By controlling the rotation speed and the direction of rotation of the hot spot (hot spot) as shown in Figure 2 intensively.

A flow path of air will be described with reference to FIG. 5. By providing the duct unit of the present invention, the inner space of the side cover 230, the upper slot 223, the intake duct 270, the cooling fan 250, the exhaust duct 260 and the front slot 130 in sequence Through the heat (A1) trapped in the inside of the side cover 230 is discharged to the outside.

3 to 5, both side portions of the intake duct 270 facing the upper slot 223 intensively suck the heat A1 inside the side cover 230. The central portion of the intake duct 270 facing the upper side of the exhaust duct 260 covers the upper side of the exhaust duct 260 through which hot heat passes and doubles heat transfer toward the controller 120 together with the exhaust duct 260 itself. To block.

Therefore, the heat of the space closed by the heat insulating material 240, the side cover 230, and the top panel 220 can be actively taken out by the duct unit. Thus, generation of hot spots on the side cover 230 can be suppressed, and the amount of heat transfer of the controller 120 can be reduced.

Although embodiments according to the present invention have been described above, these are merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments of the present invention are possible therefrom.
