Description

  The present invention relates to a fryer for frying ingredients.

  In a fryer for frying ingredients, when frying the ingredients while applying an electric field to the oil stored in the oil storage tank, improving the taste of the cooked ingredients, shortening the cooking time, and reducing the oil temperature It is known that excellent effects such as reduction and prevention of oil deterioration can be obtained.

  In order to apply an electric field to the oil stored in the oil storage tank, an electrode for forming an electric field may be provided in the oil storage tank, and various electrode structures have been proposed. For example, in Patent Document 1, an electric field forming unit having a box-shaped fixed electrode that closes five surfaces except the upper surface and a movable electrode that has an openable and closable lid structure that closes the upper surface is provided in an oil tank of a fryer, In the space closed by the fixed electrode and the movable electrode, the entire surface of the six sides, which are the electrodes, is used for frying the material while applying an electric field to the oil, thereby cooking the material without frying unevenness. A fryer that can do is disclosed.

  However, the fryer described in Patent Document 1 does not assume that the material is taken in and out of the oil storage tank by using a metal net. For example, in the fryer described in Patent Document 1, when the movable electrode provided in the oil storage tank comes into contact with the metal net, a high voltage is applied to the metal net, and the metal net is made. There was a risk that the user of the fryer handling the item might get an electric shock. Then, it is necessary to take out and put in the ingredients to be fry cooked in the oil storage tank by using a wooden chopstick or the like, which is inconvenient when performing fry cooking of a large amount of ingredients.

  Further, in Patent Document 2, an electrode inside the oil storage tank disposed inside the oil storage tank is brought into contact with an electrode plate disposed inside the frying basket to induce an electric field on the electrode plate to store the oil storage tank. Disclosed is a fryer capable of cooking while an electric field is applied to the oil inside. The fryer described in Patent Document 2 is easier to introduce than the fryer described in Patent Document 1, but if frying residue accumulates on the electrode in the oil storage tank disposed in the oil storage tank, the electrode There is a problem that the plate cannot be brought into contact with the electrode in the oil storage tank, so that the electric field cannot be applied to the oil in the oil storage tank.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the description of the embodiments and the drawings, and may be implemented in various modes without departing from the scope of the invention.

<Structure example 1>

  1A and 1B are schematic views showing an example of a fryer of the present invention, wherein FIG. 1A is a perspective view and FIG. 1B is a side view inside an oil storage tank. The fryer of the present invention comprises an oil storage tank section (0101) and a basket (0102). The basic structure is similar to that of a normal fryer for frying ingredients without applying an electric field to the oil stored in the oil storage tank. By immersing the basket in the basket, the ingredients put inside the basket are fried and cooked. Here, the difference from the ordinary fryer is that the car itself is used as an electrode for forming an electric field by energizing the car with an alternating current when the car is immersed in oil.

(Oil storage section)
FIG. 2 is a schematic view showing an example of the oil storage tank portion of the fryer of the present invention, (a) is a perspective view and (b) is a side view. The oil storage tank portion is configured to include an oil storage tank (0111) of which at least a part of the inner surface is made of a metal material plate, and is provided with an oil storage tank side fixing portion and an energization portion.

(Oil tank)
The oil storage tank (0111) is a space for storing oil for frying the ingredients, and at least a part of the inner surface (0112) is made of a metal material plate. Here, the “inner side surface” refers to the inner side surface and bottom surface of the oil storage tank. When alternating current is applied to the car, an electric field is formed between the metal material plate on the inner surface of the oil storage tank and the side surface of the car, and the electric field is applied to the oil stored in the oil storage tank. It should be noted that it is not necessary that the entire inner surface of the oil storage tank be made of a metal material plate, as in “at least a part of the inner surface”. Further, the inner surface may be formed of the metal material plate itself, but for example, the surface of the metal material plate may be covered with an insulating resin (for example, Teflon (registered trademark)). When the surface of the metal material plate is covered with an insulating resin, the cage and the metal material plate can be insulated.

  It is necessary to heat the oil stored in the oil storage tank to a high temperature when cooking the ingredients, and the oil storage tank section has a heating unit (not shown) for heating the oil stored in the oil storage tank to a high temperature. ing. The oil can be heated to a high temperature by using, for example, an electric heating type or gas type heater.

(Fixed part on oil reservoir side)
The oil storage tank side fixing portion is provided for arranging the car in the oil storage tank so that the car is immersed in the inner surface without energization. "To immerse the car in the oil storage tank without energizing the inner surface of the car" means that the metal net forming the car and the metal material plate forming the inner surface of the oil storage tank are not energized. , Shows that the car is placed by immersing it in the oil stored in the oil storage tank. If the metal material plate and the cage are energized, the metal material plate and the cage become equipotential, and an electric field cannot be formed between the metal material plate and the cage. The structure of the oil storage tank side fixing portion is not particularly limited, but, for example, when the car side fixing portion described later is configured by a hook, a hooking device (0113) for hooking the hook as the oil storage tank side fixing portion. May be provided adjacent to the oil storage tank.

(Energization part)
The current-carrying part is a current-carrying electrode arranged on the upper part of the oil storage tank on the side facing the working side surface of the oil storage tank, and is an inner surface for supplying alternating current to the metal net when a basket is placed in the oil storage tank. And an energized electrode insulated. An alternating current is supplied to the energizing electrode (0116) from the power supply (0114) through the cable (0115). The fryer of the present invention can use the car itself as an electrode for forming an electric field by applying an alternating current to the car through the current-carrying electrode. Note that the frequency of the alternating current is not particularly limited, and for example, a configuration in which an alternating current having a frequency of 50 kHz to 60 KHz is supplied to the current-carrying electrode may be used. Also, regarding the magnitude of the voltage supplied from the power source, a voltage of several V to several tens of V (for example, 3 to 10 V) may be supplied to the car.

  The work side surface (0117) indicates the side surface of the oil storage tank on the side where the user of the fryer carries out work such as taking in and out of the car into and from the oil storage tank. That is, the “side surface of the oil storage tank that faces the work side surface” refers to the inner surface of the oil storage tank that faces the work side surface. Here, the “upper part of the oil storage tank facing the work side surface” refers to the upper part of the inner side surface of the oil storage tank facing the work side surface, for example, the side facing the work side surface of the oil storage tank. It shows a portion above the center of the inner side surface in the height direction. Therefore, the current-carrying electrode may be provided on the inner surface of the oil storage tank or on the upper portion of the oil storage tank. When the current-carrying electrode is provided on the inner surface of the oil storage tank, the current-carrying electrode may or may not be immersed in the oil stored in the oil storage tank.

  If the configuration is such that the energizing electrode is provided on the bottom surface of the oil storage tank as described in Patent Document 2, frying dregs that accumulate in the oil storage tank may accumulate on the energizing electrode, which may interfere with the energization of alternating current to the car. . Therefore, by disposing the current-carrying electrode on the side surface of the oil storage tank or on the upper part of the oil storage tank, frying dregs do not accumulate on the current-carrying electrode. Therefore, it is possible to prevent the situation in which the dregs interfere with the energization of the alternating current to the car.

  Further, when the energizing electrode is provided on the side surface of the work, the user of the fryer may come into contact with the energizing electrode and receive an electric shock. Therefore, by providing the energizing electrode on the side facing the work side surface, it is possible to minimize the situation in which the user of the fryer is electrocuted.

  The current-carrying electrode needs to be insulated from the inner surface. If the current-carrying electrode and the inner side surface are electrically connected, the inner surface of the cage is equipotential if an alternating current is supplied through the current-carrying electrode. Then, an electric field cannot be formed between the cage and the inner surface. In the example shown in FIG. 2, an insulating portion (0118) is provided between the inner surface of the oil storage tank and the current-carrying electrode.

  It is preferable that the output of the power supply of the current-carrying portion is adjusted so that the magnitude of the electric field formed between the inner surface of the car and the inner surface is always within a certain range. For example, if the output of the power supply is always kept constant, the magnitude of the electric field formed inside the car will change according to the amount of material charged into the car, the composition, the moisture content, etc. It becomes necessary to adjust the processing time and the processing temperature of the material for each cooking. Therefore, by adopting a configuration in which the output of the power source is adjusted so that the magnitude of the electric field formed between the basket and the inner side surface is constant, it is possible to stabilize the amount of the material regardless of the composition, composition, and water content. You can cook.

(Basket)
3A and 3B are views showing an example of the basket of the fryer of the present invention, wherein FIG. 3A is a perspective view and FIG. 3B is a side view. In the fryer of the present invention, the car (0102) is made of a metal net (0121) and is composed of a car-side fixing part and a power receiving part. It should be noted that even though the side surface forming the car is composed of a metal net, for example, the surface of the metal net may be covered with an insulating resin.

  The phrase "made of a metal net" means that the side surface of the car is made of a metal net. It should be noted that the term "side surface forming the car" means not only the side surface of the car but also the bottom surface. By constructing a metal net on the side of the car, by passing an alternating current to the car, the metal net of the car is used as an electrode for forming an electric field, and the side of the car and the inner surface of the oil storage tank are used. An electric field can be formed between and. Further, by setting the electric potential of the inner side surface of the oil storage tank to be higher than the electric potential of the car, an electric field can be formed inside the car.

  The “metal net” is not particularly limited, and for example, the metal net may be made of punching metal (see FIG. 3) or wire (see FIG. 3-2). Further, the car may be configured by connecting a plurality of metal nets using welding or the like, but if configured to be manufactured by extrusion molding of a single metal plate, due to poor contact at the welding location This is preferable because it is possible to prevent a situation in which alternating current is not uniformly supplied to the entire metal net.

  The size and shape of the car can be appropriately designed according to the oil storage tank. That is, the fryer of the present invention can be introduced regardless of the size of the oil storage tank. Further, the size, shape, arrangement, etc. of the metal mesh (or through hole) are not particularly limited.

(Cage side fixed part)
The car-side fixing portion is provided to cooperate with the oil storage tank-side fixing portion to arrange the car in the oil storage tank without energizing the inner surface of the car. "Coupled with the oil storage tank side fixed portion" indicates that, for example, the oil storage tank side fixed portion and the car side fixed portion are engaged with each other. Although the configuration of the car-side fixing portion is not particularly limited, in the example shown in FIG. 3, the car-side fixing portion is configured by a hook (0122), and the hook is hooked on the hooking device of the oil storage tank-side fixing portion. As a result, the car is arranged in the oil storage tank. The hook may be connected to a metal net forming a car by welding, for example. "To arrange the car in the oil storage tank without energizing the inner side surface" means to arrange the metal net forming the car and the metal material plate forming the inner side surface of the oil storage tank without energizing. Shows.

(Power receiving unit)
The power receiving unit is provided to receive power from the current-carrying electrode and to supply current to the metallic net that constitutes the car. That is, the power receiving unit is in conduction with the metal net, and by bringing the power receiving unit into contact with the current-carrying electrode, alternating current is conducted from the current-carrying electrode to the metal net through the power receiving unit. In the example shown in FIG. 3, the power receiving pad (0123) that is in conduction with the metal net is provided at the contact portion with the current-carrying electrode. However, for example, in the case where the power receiving pad is not provided, the power receiving portion is It indicates the contact portion with the current-carrying electrode.

(handle)
It is preferable that the car is provided with a handle (0124) that is insulated from the metal net forming the car. By providing the handle, the user of the fryer can easily take the car in and out of the oil storage tank. Here, since the alternating current power is supplied to the metal net when the material is cooked, the metal net and the handle must be insulated. Further, when the car is immersed in high temperature oil, the metal net forming the car becomes extremely hot, so that the handle is preferably made of a material having a low thermal conductivity. In the example shown in FIG. 3, the car is provided with a handle by welding a part of the handle to a metal net.

(Outline of electric field)
FIG. 4 shows an outline of an electric field formed during cooking of the fryer of the present invention. Shown in this figure is an example in which the car shown in FIG. 3 is used. (A) In the case where the electric potential of the car due to the alternating current applied to the car is represented by V1sinωt (t is time) and the electric potential of the metal material plate of the oil storage tank is represented by V2, the case of V1> V2 is represented by ( b) shows the case where V1 <V2. For the sake of explanation, the other configurations except the oil storage tank and the car are not shown, and the outline of the electric field formed when the car is immersed in the oil storage tank is shown. In addition, the examples shown below are assumptions at the present time, and the outline of the electric field formed is still under study.

  In the case of (a), when an alternating current is applied to the car, an electromotive field (0401) is formed mainly between the car (0102) and the inner surface (0112) of the oil storage tank (0111). An electric field is applied to the oil stored in. The oil is convective in the oil tank, and the material inside the car is fried by the oil to which the electric field is applied. On the other hand, in the case of (b), even if an alternating current is applied to the car, the electric potential of the car is larger than the electric potential of the metal material plate of the oil storage tank. An electric field is formed inside.

  Although an example of the configuration of the fryer of the present invention has been described above, the fryer of the present invention is not limited to the above configuration. Below, another structural example of the fryer of the present invention will be shown.

<Structure example 2>

(Potential holding part)
As another configuration example of the present invention, the oil storage tank portion may have a potential holding portion that holds the metal material plate of the oil storage tank at a predetermined potential. "Holding the metal material plate at a predetermined potential" means, for example, grounding the metal material plate and holding the potential of the metal material plate at zero. The fryer of the present invention forms an electric field inside the car by forming an electric field between the car and the oil storage tank, but when the electric potential of the oil storage tank fluctuates, it forms inside the car. It is not possible to stabilize the magnitude of the applied electric field. Therefore, the electric field formed inside the car can be stabilized by grounding the metal material plate. The potential of the metal material plate may be switched.

<Structure example 3>

(Control unit)
As another configuration example of the present invention, the oil storage tank section may have a control section for controlling the energization section so that the energization is performed only when the oil storage tank side fixing section and the car side fixing section are engaged. . "When the oil storage tank side fixed portion and the car side fixed portion are engaged" means that the food is cooked by immersing the car in the oil storage tank. By configuring the fryer of the present invention to have a control unit, AC power is supplied to the car via the energizing electrode of the energizing unit only when the car is immersed in the oil storage tank to cook foodstuffs. Can be For example, if a configuration is such that alternating current power is constantly supplied to the current-carrying electrodes of the current-carrying unit, there is a risk of electric shock if the user of the fryer accidentally contacts the current-carrying electrodes. Therefore, by adopting a configuration in which the AC power is supplied to the current-carrying electrodes only when the material is cooked, the risk of electric shock can be reduced.

  FIG. 5 is a schematic view showing an example of an oil storage tank side fixing part having a control part in the fryer of the present invention, (a) is a perspective view, (b) is a side view, and (c) is a sectional view. There is. The oil storage tank side fixed portion shown in FIG. 5 is configured such that the rod is movable up and down with respect to the support column by using the metal rod (0502) supported by the pair of support columns (0501) as a current-carrying electrode. There is. For example, assuming that the car side fixing part is configured by a hook, if the hook is hooked on the rod when the car is placed in the oil storage tank, the spring (0505) supporting the rod inside the support column extends and the rod lowers. As a result, the rod comes into contact with the electrode (0503), and the rod is fixed. Alternating current is supplied to the electrodes through a cable (0504) connected to a power source, and when the rod contacts the electrode, alternating current is also supplied to the rod. Further, since the rod and the hook are also brought into contact with each other, an alternating current is applied to the metal net constituting the car through the hook. When the car is taken out of the oil storage tank, the rod is returned to the upper part of the support by the force of the spring, the rod and the electrode are separated from each other, and no alternating current is supplied to the rod. The electrode provided on the oil tank side fixed portion shown in FIG. 5 is provided at a position where the user of the fryer normally does not come into contact with it, so that the user of the fryer can be prevented from receiving an electric shock. In the example shown in this figure, the oil tank side fixed part and the current carrying part, and the car side fixed part and the power receiving part are the same, as will be described in the fourth structural example.

<Structure example 4>

  FIG. 6 is a schematic view showing another example of the fryer of the present invention, in which (a) is a perspective view and (b) is a side view. In the fryer shown in FIG. 6, the fixed part on the oil storage tank side is the same as the conducting part, and the fixed part on the car side is the same as the power receiving part. That is, the hooking device provided as the oil tank side fixed part in FIG. 2 is configured to be used also as the current-carrying part by energizing alternating current from the power supply through the cable. In this case, at least a portion of the hooking device that comes into contact with the cage-side fixing portion and the power receiving portion is made of a conductive substance as a current-carrying electrode, and the current-carrying electrode and the inner surface of the oil storage tank are insulated. Further, the hook provided on the car as the car-side fixing portion is also used as the power receiving portion, and the metal net is energized through the hook. In this case, the hook and the metal net need to be electrically connected, and the hook is preferably made of a conductive substance. By making the oil tank side fixed part and the current carrying part or / and the car side fixed part and the power receiving part the same, the number of parts constituting the fryer can be reduced. An insulating support (0601) is provided on the inner surface of the oil storage tank in order to prevent contact between the metal net forming the basket and the inner surface of the oil storage tank. It may be provided not only on the inner side surface of the oil storage tank but also in a car, for example. Further, the support may not be provided as long as the metal net and the inner side surface do not come into contact with each other.

<Structure example 5>

  FIG. 7 is a schematic view showing another example of the configuration of the car of the fryer of the present invention, (a) is a perspective view, (b) is a side view when immersed in an oil storage tank. There is. The car shown in FIG. 7 is made of an insulating material (0701) above the region where cooking oil is to be immersed in the oil storage tank of the car. The "scheduled cooking oil immersion area" is the area of the side of the car that is planned to be immersed in the cooking oil when the car is immersed in the oil storage tank, and the "upper side of the cooking oil immersion planned area" is That is, the area that will not come into contact with cooking oil. Since the depth of the cooking oil stored in the oil storage tank changes depending on the amount of the material to be put inside the car, the cooking oil immersion planned area also changes. Therefore, "above the cooking oil immersion planned region" is not necessarily strict, and for example, when the car is immersed in the oil storage tank, a part of the insulating material may be immersed in the cooking oil.

  The reason why the upper side of the cooking oil immersion planned area is made of an insulating material is to prevent the electric shock of the user of the fryer. While the metal net that composes the basket is supplied with AC power when cooking the ingredients, there is a risk that the fryer user may accidentally come into contact with it and receive an electric shock if the portion is not immersed in cooking oil. Occurs. Therefore, by configuring the portion not soaked in the cooking oil with the insulating material, the electric shock of the user of the fryer can be prevented.

  It should be noted that "the upper side of the cooking oil immersion planned area is made of an insulating material" means, for example, of the metal nets forming the side surface of the car, the area above the cooking oil immersion planned area is not a metal net. Although it may be made of an insulating material, the surface of the metal net in such a region may be covered with an insulating resin (for example, Teflon (registered trademark)).

  Further, as described in the configuration example 2, when the metal material plate of the oil storage tank is held at a predetermined potential which is not 0, the inside surface of the oil storage tank is also made of an insulating material above the cooking oil immersion planned region. Preferably.

<Structure example 6>

  FIG. 8 is a schematic view showing another example of the basket of the fryer of the present invention, (a) is a perspective view, and (b) is a side view as seen from the handle side. The car shown in FIG. 8 has a rectangular parallelepiped shape like the car described above, but when the whole car is divided line-symmetrically, a pair of metal nets (0801, 0802) sandwich the insulating plate (0803). It is made up of shapes. In the example shown in FIG. 8, the insulating plates are provided at three positions, that is, the side surface to which the handle is attached, the side surface opposite to the side surface, and the bottom surface. The configuration is not particularly limited. Note that the connection between the metal net and the insulating plate may be performed via a screw (0806), for example, as shown in (c) as a cross-sectional view of the connecting portion between the metal net and the insulating plate. . Further, a handle (0804) and a hook (0805) are attached to the car shown in FIG. 8 in the same manner as the car described above.

  When the car shown in FIG. 8 is used, since the pair of metal nets are insulated by the insulating plate, it is possible to apply alternating current to only one of the pair of metal nets and ground the other. . For example, in the case of using the oil storage tank section described in the configuration example 1, two energizing electrodes for energizing alternating current are provided to each of a pair of metal nets as energizing sections, and only one side is energized by alternating current, By configuring the other one to be grounded, it is possible to supply alternating current to one of the metal nets and ground the other one. Further, in the case of the fryer in which the oil tank side fixed part and the current carrying part and the car side fixed part and the power receiving part are the same as described in the configuration example 4, two hooking devices equipped with current carrying electrodes are provided, and one of the hooking devices is provided. By providing a structure in which alternating current is supplied only to the current-carrying electrodes and the other one is grounded, it is possible to supply alternating current to one of the metal nets and ground the other.

  FIG. 9 shows an outline of an electric field formed during cooking of a fryer using the car of this configuration example, and (a) shows the potential of the car due to the alternating current supplied to the car as V1sinωt (t is time). In the case where the potential of the metal material plate of the oil storage tank is represented by V2, V1> V2 is shown, and (b) shows V1 <V2. For the sake of explanation, the other configurations except the oil storage tank and the car are not shown, and the outline of the electric field formed when the car is immersed in the oil storage tank is shown. In addition, the examples shown below are assumptions at the present time, and the outline of the electric field formed is still under study.

  In the case of (a), an electromotive field (0901) is formed between a pair of metal nets that mainly form a car, and the electric field is applied to the oil inside the car. Further, an electrodynamic field is also formed between the metal net to which alternating current is applied and the inner surface of the oil storage tank. On the other hand, in the case of (b), an electrokinetic field is formed between the metal net, which is mainly energized by alternating current, and the inner surface of the oil storage tank.
