  The main problem to be solved by the present invention is that, in this type of fryer, when it is necessary to extract water and oil from the storage tank constituting the flyer, only oil is easily extracted from the storage tank before the water is extracted. The point is that it can be extracted properly.

  In order to achieve the above object, according to the present invention, the fryer has a bottom discharge part closed at the bottom of the tank so as to be openable by a valve, and has an upper discharge part at the top of the tank. A storage tank having a water storage space on the side and an oil storage space above the storage tank, and an oil heating means stored in the oil storage space, and the water storage space below the oil storage space Water supply means. The storage tank further includes an intermediate discharge portion that is closed by a valve between the bottom discharge portion and the upper discharge portion, and the lower portion of the intermediate discharge portion is used as the water storage space, and the lower discharge portion is disposed below the upper discharge portion. However, one of the best modes of the present invention is to make the oil storage space on the intermediate discharge portion.

  When it becomes necessary to extract water and oil from the storage tank by washing or the like, supply of water into the storage tank is started by the water supply means. By supplying this water, the upper surface level of the water layer in the storage tank rises, and when the upper surface level of the oil layer in the storage tank reaches the upper discharge part, oil is gradually discharged from the upper discharge part to the outside of the tank. The extraction of oil from the storage tank is completed when the upper surface level of the water layer in the storage tank reaches the upper discharge part. The water remaining in the storage tank is extracted from the storage tank by opening the bottom discharge part.

  According to this invention, when it becomes necessary to extract water and oil from the storage tank constituting the fryer, it is possible to easily and appropriately extract only the oil from the storage tank prior to the extraction of water.

FIG. 1 is a side view of a fryer according to an embodiment of the present invention. FIG. 2 is a cross-sectional configuration diagram showing the flyer, and shows a state in which a water layer is formed in the water storage space in the storage tank. FIG. 3 is a cross-sectional configuration diagram showing the fryer, and shows a state in which an oil layer is formed in the oil storage space in the storage tank. FIG. 4 is a cross-sectional configuration diagram showing the fryer, and shows a state in which oil in the oil layer in the storage tank is being extracted. FIG. 5 is a cross-sectional configuration diagram showing a fryer, and shows a state in which water in the water layer in the storage tank is drawn out.

  Hereinafter, a typical embodiment of the present invention will be described with reference to FIGS. The flyer according to this embodiment stores oil O (cooking oil) on the water W stored on the bottom side of a single storage tank T to form an oil layer, and heats the oil O of this oil layer. This is what fried food can be cooked. Fried dregs and the like produced in the oil layer by such cooking settle below the boundary surface S between the oil layer and the water layer made of the water W, and the oil O in the oil layer is kept in a state where such fried dregs and the like are not mixed. It is like that.

  In the illustrated example, the storage tank T has a side surface 1 and a bottom surface 2, and the top surface is open. The storage tank T is formed in a narrow body portion 5 whose cross-sectional area is smaller than that of the thick body portion 4 on the open portion 3 side where the upper surface level O ′ of the oil layer is located. It has become so. Between the thick body part 4 and the thin body part 5, an intermediate body part 6 for gradually reducing the cross-sectional area of the storage tank T as it goes downward is formed. A net 7 is provided slightly above the level where the thick body 4 and the intermediate body 6 are connected, and the fried food is cooked on the net 7.

Moreover, this storage tank T which comprises the principal part of a fryer is
(1) It has a bottom discharge part 8 which is closed at the bottom of the tank so as to be openable by a valve 8a,
(2) It has the upper discharge part 9 in the tank upper part,
(3) Between the upper discharge portion 9 and the bottom discharge portion 8, there is an intermediate discharge portion 10 that is openably closed by a valve 10 a,
(4) The space below the intermediate discharge portion 10 is a storage space WS for water W, and the portion below the upper discharge portion 9 and above the intermediate discharge portion 10 is a storage space OS for oil O.

  In the example shown in the drawing, the bottom discharge portion 8 includes a lower end of an elbow 8c having an upper end communicating with a through hole 8b formed in one of the side surfaces 1 of the storage tank T outside the storage tank T, and a discharge nozzle 8d. A valve 8a is provided between the two. More specifically, the elbow 8 c is provided in the narrow body portion 5 in the storage tank T so that the lower edge of the upper end of the pipe opening is positioned at the same level as the bottom surface 2 of the storage tank T. Reference numeral 8e in the drawing is a lever for opening and closing the valve. In FIGS. 1 to 4, the lever is in the valve closing position.

  Further, the upper discharge portion 9 is formed on one of the side surfaces 1 at a location above the connection location with the intermediate barrel portion 6 in the thick barrel portion 4 of the storage tank T and below the opening portion 3. And a discharge pipe 9b in which one end of the pipe communicates with the through hole 9a outside the storage tank T.

  Moreover, the intermediate | middle discharge | emission part 10 is a valve | bulb between the lower end of the elbow 10c which made the upper end connected to the through-hole 10b formed in one of the side surfaces 1 of this storage tank T on the outer side of the storage tank T, and the discharge nozzle 10d. 10a is provided. More specifically, the elbow 10 c has an upper end communicating with the storage tank T on the upper side of the narrow body 5. Reference numeral 10e in the drawings denotes a lever for opening and closing the valve. In each drawing, the lever is in a valve closing position.

  In addition, the flyer includes water W supply means 12 for the water W storage space WS below the oil O storage space OS in the storage tank T. In the illustrated example, the supply means 12 for the water W is constituted by a water supply pipe 12 a having one end communicating with the storage tank T on the tank bottom side of the storage tank T. Reference numeral 12b in the drawing is a valve provided in the middle of the water supply pipe 12a, and water W is supplied from the water supply pipe 12a into the storage tank T by opening the valve 12b.

  After supplying the water W into the storage tank T from the supply means 12 to a level exceeding the intermediate discharge portion 10 in a state where both the bottom discharge portion 8 and the intermediate discharge portion 10 are closed, the intermediate discharge portion 10 is opened. Thus, the water W can be stored in the storage tank T so that the upper surface level W ′ of the water layer is positioned directly below the intermediate discharge portion 10. (FIG. 2) Next, the intermediate discharge unit 10 is closed, and the oil O is supplied into the storage tank T to a level above the level at which the mesh 7 is provided and does not reach the upper discharge unit 9. Thereby, the said oil layer is formed on a water layer and fried food cooking is enabled in this oil layer. (Figure 3)

  The fryer includes a heating means 11 for the oil O stored in the storage space OS for the oil O, and a supply means 12 for the water W into the storage tank T. In the illustrated example, the heating means 11 for the oil O is an electric heater in which a tubular heater portion 11b is arranged in the thick barrel portion 4 on the intermediate barrel portion 6 of the storage tank T and below the net 7. It is comprised by the apparatus 11a. Reference numeral 11c in the figure denotes a control unit of this heater device. In addition, as the heating means 11, a known heater device such as a gas heater may be used.

  When it becomes necessary to extract water W and oil O from the storage tank T by washing or the like, the supply of water W into the storage tank T is started by the water W supply means 12. By supplying this water W, the upper surface level W ′ of the water layer in the storage tank T rises, and when the upper surface level O ′ of the oil layer in the storage tank T reaches the upper discharge part 9, the upper discharge part 9 moves out of the tank. Oil O is gradually discharged. (FIG. 4) When the upper surface level W ′ of the water layer in the storage tank T reaches the upper discharge part 9, the extraction of the oil O from the storage tank T is completed, the valve 12b is closed and the supply means 12 is closed. The supply of water W is stopped. Reference symbol P in the figure is a container that receives oil O fed from a discharge pipe 9 b that constitutes the upper discharge portion 9. The water W left in the storage tank T is extracted from the storage tank T by opening the bottom discharge part 8. (FIG. 5) Since the oil O stored in the storage tank T sinks fried residue and the like, the upper layer side is relatively clean, and the degree of contamination increases as it approaches the lower layer. In the fryer according to this embodiment, the oil O stored in the storage tank T can be extracted from the upper layer side by supplying the water W from the water W supply means 12, so that the upper layer side The comparatively clean oil O in (1) can be extracted and reused without being mixed with the remaining oil O. In the case of performing the extraction immediately after the heating by the heating means 11 is stopped, after the relatively high temperature upper oil O is extracted, the supply of the water W from the supply means 12 is once stopped and the tank is still It is possible to easily remove fried residue from the lower temperature lower oil O inside by manual work using a net or the like, and the lower layer oil O is also immediately after the use of the fryer is stopped. It can also be made into a reusable state and extracted from the storage tank T.
