Description

[Technical field]

[0001] The present invention relates to a fryer having a storage tank having an oil layer and a water layer. [Background technology]

[0002] Conventionally, fryers equipped with a storage tank having an oil layer and a water layer are disclosed in Patent Documents 1 and 2. Both Patent Documents 1 and 2 aim to prevent deterioration of the oil by dropping fried food residue generated in the oil layer into the water layer, thereby extending the life of the oil.

[0003] In Patent Documents 1 and 2, the prevention of oil deterioration by dropping fried debris into the water layer is specifically carried out as follows.

[0004] That is, in Patent Document 1, a nozzle on the side of the water tank of the storage tank sprays a water flow slightly downward to guide the fried scraps into a scraps collection section. Also, in Patent Document 2, the fried scraps are dropped into the water tank of the storage tank, and the water in the water tank flows into the filtration water tank through a circulation pipe together with foreign matter from a water intake port at the bottom of the tank by the suction force of a pump, where it is filtered by a filter in the filtration water tank and returned to the storage tank through the circulation pipe.

[0005] [Patent Document 1] JP 2010-172677 A [Patent Document 2] JP 2010-183971 A Summary of the Invention [Problem to be solved by the invention]

[0006] In Patent Documents 1 and 2, since high-temperature oil is stored in the storage tank, a heat-resistant metal such as stainless steel is used as the material for the entire fryer, particularly the material for forming the storage tank, in order to impart heat resistance to the storage tank.

[0007] Because the oil vat is formed from opaque metal, the fryers described in Patent Documents 1 and 2 have the problem that when checking the condition of the fried food, it is not possible to check the oil vat from the side, but can only be checked from above the oil vat, making it difficult to accurately grasp the condition of the fried food.

[0008] Furthermore, as described above, the fryers disclosed in Patent Documents 1 and 2 have a relatively complicated configuration, which causes a problem in that cleaning and maintenance of the fryers are cumbersome.

[0009] The present invention has been made in consideration of the above-mentioned circumstances, and has an object to provide a fryer that has a simpler configuration than conventional devices, prevents deterioration of oil for deep-frying, and makes it easier and more accurate to grasp the condition of the fried foods than conventional devices. [Means for solving the problem]

[0010] (1) The present invention comprises a storage tank formed of a light-transmitting material, having a storage section capable of storing water, and having a water layer formed by the water stored in the storage section; and a tubular member that is arranged at a desired position in the storage tank, formed in a cylindrical shape from a light-transmitting material, has an inner wall and an outer wall connected to the inner wall at a predetermined distance and arranged outside the inner wall, and is capable of storing oil for deep-frying in an internal space formed by the inner wall, wherein at least the inner wall of the tubular member is formed of a light-transmitting material having heat resistance, and a heating means is arranged at a predetermined position of the oil layer formed by the oil stored in the internal space.

[0011] According to the present invention having the above feature (1), at least the inner wall of the cylindrical member is made of a heat-resistant light-transmitting material, and the heating means is disposed at a predetermined position in the oil layer formed in the internal space, so that when checking the state of the fried food put into the heated oil layer, it is possible to easily visually check not only from above but also from the side. Also, it is possible to easily visually check the state of the oil.

[0012] Furthermore, according to the present invention, since it is sufficient to have a configuration including a storage tank and a cylindrical member that is placed at a desired position of the storage tank, it is possible to make the fryer have a simpler configuration than conventional ones.

[0013] (2) In the present invention, the cylindrical member is characterized in that at least the inner wall is made of a light-transmitting material having heat resistance to temperatures of 50 degrees Celsius or more and 250 degrees Celsius or less.

[0014] According to the present invention having the above characteristic (2), at least the inner wall of the tubular member is formed from a light-transmitting material having a heat resistance of 50 degrees Celsius or more and 250 degrees Celsius or less, so that the temperature of the oil layer can be heated to an optimum temperature for frying foods.

[0015] (3) In the present invention, the cylindrical member is characterized in that a predetermined gap between the inner wall and the outer wall is formed as an air layer.

[0016] According to the present invention having the above characteristic (3), a predetermined gap between the inner wall and the outer wall of the tubular member is configured as an air layer, and therefore, heat from the oil layer is less likely to be transferred to the water layer due to insulation by the air layer.

[0017] (4) In the present invention, the cylindrical member is characterized in that the upper ends of the inner wall and the outer wall are each formed as an open end.

[0018] According to the present invention having the above feature (4), the upper ends of the inner wall and the outer wall of the tubular member are formed as open ends, and therefore an opening is formed at the upper end of the tubular member, and the heat of the oil layer can be released from the opening. As a result, the heat of the oil layer is less likely to be transmitted to the water layer.

[0019] (5) The present invention is characterized in that the heating means is disposed at a middle portion in the depth direction of the oil layer.

[0020] According to the present invention having the above characteristic (5), the heating means is disposed in the middle of the oil layer in the depth direction, so that the oil below the heating means is maintained at a temperature close to room temperature, and the heat of the oil layer is less likely to be transmitted to the water layer.

[0021] (6) In the present invention, the tubular member is formed in a cylindrical shape.

[0022] According to the present invention having the feature described above in (6), since the tubular member is formed into a cylindrical shape, it becomes possible to visually check the state of the fried food not only from above but also from the side more easily, and it becomes possible to visually check the state of the oil more easily. Effect of the Invention

[0023] According to the present invention, it is possible to provide a fryer that has a simpler configuration than conventional ones, prevents deterioration of oil for frying, and makes it easier and more accurate to grasp the condition of the fried food than conventional ones.

[0024] In addition, the present invention has the effect of providing a fryer that has a simpler configuration than conventional ones and that allows for easy cleaning and maintenance of the fryer. [Brief description of the drawings]

[Diagram 3] 3 is a cross-sectional view taken along the arrows AA in FIG. 2. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a schematic diagram showing a fryer according to one embodiment of the present invention, Fig. 2 is an enlarged plan view of the vicinity of a cylindrical member when the fryer shown in Fig. 1 is viewed from above, and Fig. 3 is a cross-sectional view taken along the arrows AA in Fig. 2. The arrows shown in the figures indicate the up-down direction (this is an example).

[0027] A fryer 1 according to this embodiment shown in Fig. 1 is a device for frying food, and includes a storage tank 2, a cylindrical member 3, and a heating means 4. Each component of the fryer 1 will be described below.

[0028] First, the storage tank 2 will be described. 1 is made of a light-transmitting material and has a rectangular cylindrical shape with a bottom when viewed from above, and has a storage section 6 capable of storing water 5. The "light-transmitting material" is a material having light transmittance that allows the inside of the storage section 6 to be visually confirmed from the outside. The storage section 2 has a water layer 7 formed by the water 5 stored in the storage section 6.

[0029] As shown in FIG. 1, the tank 2 may have fish 20, such as goldfish, and water plants 21 placed in the storage section 6.

[0030] Next, the cylindrical member 3 will be described. 1 to 3 is made of a light-transmitting material and has an overall cylindrical shape, and has an inner wall 8 and an outer wall 9 disposed outside the inner wall 8. The cylindrical member 3 is disposed on the upper layer side of the water layer 7.

[0031] Although detailed description will be omitted in this embodiment, the cylindrical member 3 is supported by one or more support arms 12 (see FIG. 1) connected to the side wall 11 of the storage tank 2 (this is considered as one example).

[0032] The inner wall 8 shown in Fig. 2 is made of a light-transmitting material and has a cylindrical shape. The outer wall 9 shown in Fig. 2 is made of a light-transmitting material and has a cylindrical shape, and is connected to the inner wall 8 with a predetermined gap therebetween and disposed outside the inner wall 8.

[0033] In this embodiment, the inner wall 8 is made of a light-transmitting material having heat resistance. More specifically, the inner wall 8 is made of a light-transmitting material having heat resistance to an optimum temperature for frying the fried food 18 (i.e., 50 degrees Celsius or more and 250 degrees Celsius or less).

[0034] The inner wall 8 has an internal space 13 formed therein, and is configured so that oil 14 for frying can be stored in the internal space 13. An oil layer 15 (see Figs. 1 and 3) is formed by the stored oil 14 in the internal space 13. A heating means 4 is disposed at a predetermined position in the oil layer 15.

[0035] 3, in this embodiment, the upper ends of the inner wall 8 and the outer wall 9 of the cylindrical member 3 are formed as open ends. Therefore, the cylindrical member 3 has a configuration in which an opening 16 is formed at the upper end.

[0036] 3, in the present embodiment, the lower ends of the inner wall 8 and the outer wall 9 of the cylindrical member 3 are connected to a bottom wall 10. A predetermined gap between the inner wall 8 and the outer wall 9 is formed as an air layer 17. The above-mentioned "predetermined gap" is a gap that allows heat generated when the oil layer 15 is heated to easily escape from the opening 16 and makes it difficult for the heat to be transmitted to the water layer 7.

[0037] Next, the heating means 4 will be described. The heating means 4 is capable of heating the oil 14 to an optimum temperature (e.g., 50 degrees Celsius or more and 250 degrees Celsius or less) for frying food 18 (see FIG. 1), and in this embodiment, an electric heater is used. The heating means 4 is disposed in the middle of the oil layer 15 in the depth direction (i.e., the vertical direction).

[0038] Next, how to use the flyer 1 will be described. As shown in Fig. 1, fryer 1 is placed on a flat surface 19. Water 5 is stored in storage section 6 of storage tank 2 to form a water layer 7. Oil 14 is stored in an amount sufficient to efficiently fry food 18 in an internal space 13 of inner wall 8 of cylindrical member 3 to form an oil layer 15. The water layer 7 is disposed below internal space 13.

[0039] In the above state, the oil 14 in the oil layer 15 is heated by the heating means 4 to an optimum temperature for frying the deep-fried food 18 (for example, 50 degrees Celsius or more and 250 degrees Celsius or less).

[0040] By heating the oil 14 in the oil layer 15, the temperature of the oil 14 arranged above the heating means 4 reaches an optimum temperature for frying the food 18, and then the food is fried by putting ingredients for frying into the oil layer 15.

[0041] According to this embodiment, at least the inner wall 8 of the cylindrical member 3 is made of a heat-resistant light-transmitting material, and the heating means 4 is disposed at a predetermined position in the oil layer 15 formed in the internal space 13, so that when checking the state of the fried food 18 placed in the heated oil layer 15, it is possible to easily visually check not only from above but also from the side. Also, it becomes possible to easily visually check the state of the oil 14.

[0042] Furthermore, according to this embodiment, since the tubular member 3 is formed in a cylindrical shape, it becomes easier to visually check the state of the fried food 18 not only from above but also from the side, and it becomes easier to visually check the state of the oil 14.

[0043] Furthermore, according to this embodiment, the fryer 1 only needs to be configured with the storage tank 2 and the cylindrical member 3 disposed at a desired position in the storage tank 2, so that the fryer 1 can have a simpler configuration than the conventional one. As a result, according to this embodiment, deep-fried food 18 that is generated during frying falls from the oil layer 15 into the water layer 7 in the storage tank 2. This makes it possible to efficiently prevent deterioration of the oil 14 in the oil layer 15.

[0044] Furthermore, according to this embodiment, at least the inner wall 8 of the cylindrical member 3 is made of a light-transmitting material having heat resistance of 50 degrees Celsius or more and 250 degrees Celsius or less, so it is possible to heat the oil layer 15 to an optimum temperature for frying the fried food 18. Since the inner wall 8 has heat resistance, the inner wall 8 is unlikely to be damaged even if the temperature of the oil 14 in the oil layer 15 rises.

[0045] Furthermore, according to this embodiment, the predetermined gap between the inner wall and the outer wall of the cylindrical member is configured as an air layer, so that heat transfer from the inner wall 8 in contact with the oil layer 15 to the water layer 7 is unlikely to occur. Therefore, the temperature of the water 5 in the water layer 7 is unlikely to increase, and even if fish 20 are placed in the water layer 7, the fish 20 are unlikely to be affected.

[0046] Furthermore, according to this embodiment, since the heating means 4 is disposed at the intermediate portion in the depth direction of the oil layer, the temperature of the oil 14 disposed below the heating means 4 is maintained at a temperature close to room temperature, so that the heat of the heated oil 14 is less likely to be transmitted to the water layer 7. Therefore, also from this point of view, the temperature of the water 5 in the water layer 7 is less likely to rise.

[0047] Furthermore, according to this embodiment, the upper ends of the inner wall 8 and the outer wall 9 of the tubular member 3 are formed as open ends, and therefore an opening 16 is formed at the upper end of the tubular member 3, and heat from the oil layer 15 can be released from the opening 16. As a result, the heat from the oil layer 15 is less likely to be transmitted to the water layer 7.

[0048] Next, the effects obtained by this embodiment will be described. According to the present embodiment, it is possible to prevent deterioration of the deep-frying oil 14 with a simpler configuration than the conventional one, while making it possible to grasp the state of the deep-frying food 18 more easily and accurately than the conventional one.

[0049] In addition, according to this embodiment, since the configuration is simpler than the conventional one, cleaning and maintenance of the fryer 1 can be easily performed.

[0050] The configurations described in the above embodiments can be modified as appropriate within the scope of the present invention, and are not limited to the configurations of the above embodiments.

[0051] In the above embodiment, the storage tank 2 is formed in a rectangular cylindrical shape with a bottom when viewed from above, but is not limited thereto, and for example, a configuration in which it is formed in a cylindrical shape with a bottom may be adopted.

[0052] In addition, in the above embodiment, the tubular member 3 is formed in an overall cylindrical shape, but this is not limited to this, and it is also possible to adopt a configuration in which the tubular member 3 is formed in an overall angular tubular shape that is polygonal when viewed in a plane (triangle, square, etc.).

[0053] In addition, in the above embodiment, the inner wall 8 of the tubular member 3 is formed from a heat-resistant light-transmitting material, but this is not limited to the above, and for example, a configuration in which the entire tubular member 3 is formed from a heat-resistant light-transmitting material may be adopted.
