Description

  The present invention relates to an electric oven, in particular, an electric oven for foods, and relates to an electric oven that realizes a three-dimensional structure that does not take a place even though it has a large capacity by utilizing the structure of a rotating chain.

  Most of the electric ovens for shochu currently on the market mainly consist of "opening / closing doors with a peep window", "infrared heating tube", "rotary table", "heat reflector" and "temperature control panel of the main unit". Has been.

  These shochu facilities have a structure that supports the sweet potato using a horizontal or vertical circular turntable, and the length, width and height of the oven are affected by the circular turntable. Therefore, the space for installing these shochu facilities is considerably widened.

  In addition, the viewing window has a fixed structure in which double glass and an open / close door are integrated, and the steam generated when baking the shochu adheres to the inner glass of the viewing window, and the outer glass is also heated due to the high temperature. It will be cloudy. Since the two-layer glass is fixed on the open / close door, the viewing window cannot wipe the steam adhering to the inner glass. Therefore, the field of view of the viewing window is not clear, and the state of the shochu inside the main body cannot be clearly seen. Moreover, when the door is pulled forward and opened, and the shochu is taken out, there is a risk that the arm may touch the metal or glass on the inner wall of the door heated to a high temperature and cause burns.

  Furthermore, if the shochu is baked reasonably, it must be quickly removed from the body. Otherwise, the grilled salmon will be burnt. And the fired potatoes taken out must be sold while hot. If it cools, it will become tasteless and the product value will be lost. Once the chilled rice cake has been cooled, it will not return to its original taste even if it is reheated.

  In the process of baking shochu, it is always necessary to observe with the human eye how the shochu is burnt. The wrinkles are not uniform, the degree of baking is not uniform, and if the baking time is too long, it will burn. Even if you want to check the condition of the burn, you have to open the sliding door of the oven in order to prevent the view window from becoming cloudy, and this will cause a decrease in the internal temperature of the oven. In addition, in order to observe the shochu in the back of the oven, the swivel is moved to the front of the viewing window by moving the turntable, and then the door is opened and the condition of the grill is checked. It is considered that the thermal efficiency is lowered, and as a result, the cost is increased.

  The present invention has been made in view of the above-mentioned conventional problems, and has the following objects.

  1. An electric oven that requires less installation space than the conventional one can be provided.

  2. An electric oven capable of easily cleaning the viewing window can be provided.

  3. It is possible to provide an electric oven that can avoid the risk of burns due to skin contact with a high-temperature sliding door.

  4). An electric oven that can keep the baked food (baked rice cake) warm.

  5. An electric oven that allows easy observation of the state of food baked inside the oven can be provided.

  6). It is possible to provide an electric oven capable of preventing a large amount of internal heat from diffusing outside when food is taken out of the oven.

  In order to achieve the above object, the rotary electric oven with a hanging chain according to the present invention has the following means.

  That is, the rotary electric oven with a hanging chain according to the first aspect of the present invention includes an oven body having at least one food entrance and at least one baking condition observation window, and an upper portion and a lower portion in the oven body. A pair of sprocket shafts provided opposite to each other, two sets of sprockets provided on each of the sprocket shafts, and a pair of chains wound respectively between the sprockets facing each other in the vertical direction. , Between these chains, at least two suspension rods constructed to be rotatable around an axis parallel to the sprocket shaft, electric heating means provided in the vicinity of the rotation path of the suspension rods, and the pair A drive motor connected to at least one of the sprocket shafts of the sprocket shaft and observation of the burn condition A glass door composed of an inner glass plate fixed inside and an outer glass plate provided on the outer side of the inner glass plate so as to be openable and closable with a gap between the outer glass plate and the food doorway And a door that can be folded with the inner surface facing inward when the food doorway is opened.

  Because of this specific matter, the hanging basket that contains the food rotates up and down, so the floor area of the oven body is smaller than the conventional one, so there is no need for a large installation area and the space is limited. It can also be installed at a designated location.

  In addition, the glass door provided on the baking window is fixed only to the inner glass plate, and the outer glass plate can be opened and closed. The glass plate can be opened and wiped off, and the inner glass plate keeps the burnt window closed, so that the heat inside the oven body does not leak outside when wiping the outer glass plate. There is no possibility that the temperature in the oven body is lowered. Here, although the fogging of the inner glass plate cannot be wiped off, the field of view obtained when only the inner glass plate is clouded is far more than the field of view obtained when both the inner glass plate and the outer glass plate are clouded. Since it is good, it is possible to sufficiently observe the degree of baking of food only by wiping off the fogging of the outer glass plate.

  In addition, it is preferable that the scoring window is provided at the upper part of the oven body from the viewpoint of easy observation.

  As described above, there may be at least two hanging rods for storing food, and three or more hanging rods may be provided. Further, the hanging rod is preferably made of stainless steel from the viewpoint of heat resistance and hygiene.

  Moreover, it is preferable from the surface of operativity to arrange | position a temperature control panel in the upper part of an oven main body.

  Since the door can be folded with the inner surface facing inward when opened, the inner surface that is heated by heat during cooking is not exposed to the outside when the door is opened. For this reason, even if an arm or a hand touches the door when food is taken in or out, the touched portion becomes the outer surface of the door which is not heated, so there is no risk of burns.

  In addition, because the door is foldable, the food doorway can be made smaller while preventing burn accidents, so that the amount of heat dissipated from the food doorway can be kept small even if the door is opened when food is taken in or out. There is no risk of lowering the temperature in the oven body. That is, when the door is made of a single plate rather than a foldable type as seen in the conventional shochu equipment, a burn accident will not occur because the hand or arm touches the inner surface of the door when it is opened. To do this, it is necessary to enlarge the food doorway so that the distance between the open door and the hand or arm is maintained. Then, when the door is opened, the food doorway is greatly opened, so that the heat in the oven body is easily dissipated to the outside when the food is taken in and out, and the temperature in the oven body rapidly decreases. Absent. This point can be solved by the present invention.

  Moreover, this door may be opened and closed in the vertical direction or may be opened and closed in the horizontal direction.

  For example, an infrared heating tube can be used as the electric heating means. Moreover, as an arrangement | positioning location, the center part and lower part of an oven main body are preferable.

  A rotary electric oven with a hanging chain according to the invention of claim 2 includes an oven main body having at least one food inlet / outlet, a pair of sprocket shafts provided facing the upper and lower portions in the oven main body, and these A pair of sprockets provided in pairs on each sprocket shaft, a pair of chains wound between the sprockets facing each other in the vertical direction, and a shaft parallel to the sprocket shaft between these chains.

A CCD camera system for imaging, openably provided on the food doorway, was that and a door foldable by inward the inner surface when is opened a food product doorway.

  Because of this specific matter, the hanging basket that contains the food rotates up and down, so the floor area of the oven body is smaller than the conventional one, so there is no need for a large installation area and the space is limited. It can also be installed at a designated location.

  In addition, since the degree of baking of the food stored in the hanging basket is captured by the CCD camera system, it should be observed without being disturbed by water vapor generated from the food during cooking and without causing a temperature drop in the oven body. Can do.

  As described above, there may be at least two hanging rods for storing food, and three or more hanging rods may be provided. Further, the hanging rod is preferably made of stainless steel from the viewpoint of heat resistance and hygiene.

  Moreover, it is preferable from the surface of operativity to arrange | position a temperature control panel in the upper part of an oven main body.

  Since the door can be folded with the inner surface facing inward when opened, the inner surface that is heated by heat during cooking is not exposed to the outside when the door is opened. For this reason, even if an arm or a hand touches the door when food is taken in or out, the touched portion becomes the outer surface of the door which is not heated, so there is no risk of burns.

  In addition, because the door is foldable, the food doorway can be made smaller while preventing burn accidents, so that the amount of heat dissipated from the food doorway can be kept small even if the door is opened when food is taken in or out. There is no risk of lowering the temperature in the oven body. That is, when the door is made of a single plate rather than a foldable type as seen in the conventional shochu equipment, a burn accident will not occur because the hand or arm touches the inner surface of the door when it is opened. To do this, it is necessary to enlarge the food doorway so that the distance between the open door and the hand or arm is maintained. Then, when the door is opened, the food doorway is greatly opened, so that the heat in the oven body is easily dissipated to the outside when the food is taken in and out, and the temperature in the oven body rapidly decreases. Absent. This point can be solved by the present invention.
