The combustion chamber 62 is configured such that the upper opening 691 of the box body 69 having an upper and lower opening is opposed to the bottom surface 31 of the liquid tank 3 and communicates with a combustion gas passage 64 which is a heating gas passage described later. The gas burner 61 is inserted and installed in the box 69, and the combustion chamber 62 is located above the gas burner 61.

  Further, the lower side of the liquid tank 3 is surrounded by the bottom surface 31 of the liquid tank 3 as an upper wall, and extends from the front side to the rear side (right side in FIG. 2) of the liquid tank 3 and passes through the combustion gas. A combustion gas passage 64 for heating the liquid tank 3 is provided. The upper side of the combustion chamber 62 is connected to the combustion gas passage 64, and the combustion gas passage 64 is connected to an exhaust passage 65 provided in the back guard 22 erected on the back side of the housing 2. . In this way, the combustion gas generated in the combustion chamber 62 exchanges heat with the oil 70 in the liquid tank 3 through the liquid tank 3 in the combustion gas passage 64, heats it, passes through the exhaust path 65, and back guard. 22 is discharged to the outside of the fryer 10 through an exhaust port 66 provided at the upper end of the flier 22.

  In addition, a heat shield frame 4 that prevents the case 2 from being directly heated by heat radiated from the combustion chamber 62, the liquid tank 3, and the combustion gas passage 64 to the inside of the case 2 is provided inside the case 2. is set up.

  As shown in FIGS. 4 and 5, the heat shield frame 4 includes a front plate 41, side plates 42 and 42, and a bottom plate 43 in which a recess 419 for inserting the oil drain pipe 13 is formed. As shown in FIG. 1 to FIG. 3, it is configured between the casing 2 and the combustion chamber 62, the liquid tank 3, and the combustion gas passage 64. And the combustion gas passage 64 is enclosed. The upper end of the heat shield frame 4 is brought into contact with the liquid tank, and the upper opening of the heat shield frame 4 is closed with the liquid tank 3. That is, the upper end portions of the front plate 41 and the side plates 42 and 42 are in contact with the outer surface of the liquid tank 3 to provide airtightness above the heat shield frame 4. On the other hand, the front plate 41, the other portions of the side plates 42 and 42, and the bottom plate 43 are installed at a predetermined distance from the combustion chamber 62, the liquid tank 3, and the combustion gas passage 64. Then, this separated space defined by the heat shield frame 4 and the liquid tank 3 is heated by the heated heated air flowing by heat radiation from the combustion chamber 62, the liquid tank 3 and the combustion gas passage 64 to the inside of the housing 2. An air flow path 100 is formed.

  The combustion chamber 62 and the combustion gas passage 64 are completely surrounded by the heat shield frame 4 and the liquid tank 3 except for the rear side of the liquid tank 3. On the other hand, the liquid tank 3 is surrounded to a height substantially equal to a predetermined oil level stored in the liquid tank 3.

  As shown in FIGS. 3 and 4, the heat shield frame 4 is provided on the outer surface of the liquid tank 3 using a front plate 41, side plates 42 and 42, and a bottom plate 43 formed separately from each other. A stat bolt 99 is inserted into a bolt hole 97 provided in the upper part of the side plate 42, the side plate 42 is fixed to the outer surface of the liquid tank 3 with a nut 98, and the front plate 41 and the bottom plate 43 are connected to the front plate 41, Bolts (not shown) are inserted into the bolt holes 97 provided in the side plate 42 and the bottom plate 43, fixed using nuts, fixed to the side plates 42, 42, and assembled to the liquid tank 3. .

  By fixing the heat shield frame 4 to the liquid tank 3 in this way, the case is directly connected to the case from the fixing portion where the heat shield frame 4 and the case 2 are in contact with each other as in the case of fixing to the case 2. 2 can be prevented from conducting heat.

  As well shown in FIG. 2, the heat shield frame 4 is sealed with a liquid tank 3 at the top, and has an opening 49 that opens the entire rear end, here the rear end (right side in FIG. 2). The formed opening 49 is inserted into and communicated with the back guard 22 connected to the exhaust port 66. The bottom plate 43 is provided with an opening 431 for inserting and installing a box 69 constituting the combustion chamber 62 and forming an air intake 432 for taking air into the heated air flow path 100.

  The material of the heat shielding frame 4, that is, the front plate 41, the side plates 42 and 42, and the bottom plate 43 is preferably stainless steel, but other materials can be used without being limited to stainless steel. Further, the heat shield frame 4 may be integrally formed instead of forming the front plate 41, the side plates 42 and 42 and the bottom plate 43 as separate bodies.

  Further, it is preferable to install a heat insulating material 89 between the side plate 42 and the outer surface of the liquid tank 3 at a fixed portion of the side plate 42 to the liquid tank 3, that is, a contact portion. A heat insulating material is not specifically limited, A well-known heat insulating material can be used, for example, a glass fiber heat insulating material etc. can be used. By adopting such a configuration, it is possible to prevent the side plate 42 and the liquid tank 3 from coming into direct contact and to make it difficult to transfer the heat of the liquid tank 3 to the side plate 42. Further, it can act as a packing that fills a gap formed between the side plate 42 and the liquid tank 3 that has been distorted and deformed by heat, and heated air from the upper part of the heated air channel 100. Can be prevented from radiating heat to the housing 2.

  In addition, the front plate 41, the side plates 42 and 42, and the bottom plate 43 do not have to be provided with a heat insulating material, but by installing, the heat radiation from the heat shield frame 4 to the housing 2 is further suppressed. This is preferable. In particular, it is preferable to provide a heat insulating material 88 on the front plate 41 to protect the operation panel 11.

  The upper side 421 extending in front and rear of the fryer 10 of the side plate 42 may be horizontal as shown in FIG. 8, but as shown in FIGS. 2 and 7, the front side of the fryer 10 (in FIGS. 2 and 7). It is formed with an inclination so that the back side (right side in FIGS. 2 and 7) is higher than the left side. With such a configuration, the heated air can easily flow into the opening 49 on the rear end side of the heat shield frame 4 in the heated air flow path 100, and the exhaust of the heated air is promoted, whereby the heat shield frame body. This is because heat transfer to 4 can be suppressed and heating of the housing 2 can be further suppressed.

  In order to form the upper end side 421 of the side plate 42 so that the back side is higher than the front side of the flyer 10, as shown in FIG. 2, the side plate 42 has a rectangular shape, a bottom plate 43, and a heat shield frame. 4 may be installed diagonally so that the back side of the fryer 10 is raised. Further, as shown in FIG. 7, the side plate 42 is formed in a trapezoid whose side on the back side is longer than the front side of the fryer 10, and the bottom plate 43 is configured to install the heat shield frame 4 horizontally. You can also

  Next, the operation and action of the fryer 10 will be described mainly with reference to FIG. When the gas burner 61 is burned below the combustion chamber 62 in a state where the oil 70 is stored in the liquid tank 3, the air flowing in from the lower opening 692 of the box body 69 is shown in the combustion chamber 62 as indicated by an arrow A 0. The liquid tank 3 is heated while being passed through the combustion gas passage 64 (arrow A1). The heated liquid tank 3 heats the oil 70 in the liquid tank 3. The combustion gas passing through the combustion gas passage 64 is deprived of heat, passes through the exhaust passage 65 (arrow A2), and is discharged from the exhaust port 66 to the outside of the fryer 10 (arrow A3). On the other hand, heat is radiated from the liquid tank 3, the combustion chamber 62, and the combustion gas passage 64 to the casing 2 side opposite to the liquid tank 3, that is, into the heated air flow path 100, and as indicated by an arrow B 0, the air intake 432. The air that has flowed into the heated air flow path 100 from above is heated to become heated air, flows in the heated air flow path 100 toward the back guard 22 (arrow B1), and flows into the air holes 220 below the back guard 22 ( Together with the arrow D1), it enters the back guard 22 through the opening 49 on the rear end side of the heat shield frame 4, flows upward between the exhaust path 65 and the frame 222 of the back guard 22 (arrow B2), The gas is discharged from the exhaust port 66 at the upper end of the guard 22 (arrow B3).

  In this way, the heat shield frame 4 blocks the liquid tank 3, the combustion chamber 62, the combustion gas passage 64 and the housing 2 to prevent heat from being directly transmitted to the housing 2. The heat radiated from the tank 3, the combustion chamber 62 and the combustion gas passage 64 is discharged to the outside of the housing 2 to lower the temperature in the housing 2, thereby suppressing the housing 2 from being heated.

  In addition to the first embodiment described above, the liquid heat cooking apparatus 1 of the present invention can be configured to be appropriately modified as follows, and these embodiments are appropriately combined. It is also possible to have a configuration.

  When the liquid tank 3 is surrounded by the heat shield frame 4, it is preferable to completely cover the upper end of the liquid tank 3 by the heat shield frame 4, but only a part, for example, but not limited to this, It is good also as covering to the substantially same height as the predetermined | prescribed oil surface stored in the liquid tank 3, or substantially the same height. This is because the combustion chamber 62 and the combustion gas passage 64 are hotter than the liquid tank 3, and the temperature of the portion where the oil 70 is stored is higher than the temperature of the portion where the oil 70 is not stored. This is because, in order to prevent the heating of 2, the enclosure of only the combustion chamber 62 and the combustion gas passage 64 or the enclosure of a part of the liquid tank 3 is also effective.

  For the same reason, only the combustion chamber 62 and the combustion gas passage 64 may be covered, and the front and side surfaces of the liquid tank 3 may not be covered at all. Further, since the heated air in the heated air flow path 100 is lighter than the air in the other space in the housing 2 and tends to rise, the heat shield frame 4 is not provided with a bottom plate, and the front plate 41 is not provided. The side plates 42 and 42 are formed in a U-shaped frame shape in plan view with the upper, rear and lower sides opened, and the side surface of the liquid tank 3 and the combustion gas passage 64 with the rear and lower sides opened. And the structure which enclosed the combustion chamber 62 is also employable.

  Moreover, as shown in FIG.2 and FIG.7, the upper end edge | side 421 extended in the front and back of the fryer 10 of the side plate 42 is formed so as to be inclined so that the back side is higher than the front side of the fryer 10. However, it may be horizontal as shown in FIG. By making it horizontal, the heat shield frame 4 can be enclosed to the upper end of the liquid tank 3.

  Further, the opening 49 on the rear end side of the heat shield frame 4 is open at the entire rear end of the heat shield frame 4, but only a part of the rear end of the heat shield frame 4 may be opened. In this case, the rear side of the liquid tank 3 is also surrounded by the heat shield frame 4. Further, a pipe or the like as a heated air exhaust passage is connected to and communicated with the rear end portion of the heat shield frame 4, that is, the opening portion where the rear end or a part of the rear end side of the side plate 42 is opened. The pipe may be directly connected to the exhaust port 66, or the pipe may be inserted into the back guard 22 and connected to the exhaust port 66. In the latter case, the heated air exhaust passage is constituted by the pipe and the back guard 22.

  Further, the back guard in the above-described embodiment is further erected from the upper surface of the housing. However, if the back guard is located on the back side of the housing 2 and has an exhaust port, the back guard is installed from the upper surface of the housing. Furthermore, it is not necessary to stand up in the upper part, and it may be the same height as the upper surface of the housing. Furthermore, the liquid cooking device may not include a back guard. In this case, a pipe or the like as a heated air exhaust passage is connected to and communicated with an opening in which a part of the rear end side of the heat shield frame 4 or the side plate 42 is opened. The structure which connects to the exhaust port provided in the back side of the housing | casing 2 or the back side of a side surface is employable.

  Further, the opening 49 of the heat shield frame 4 can be connected to the exhaust passage 65, and the exhaust passage 65 can also serve as the heated air exhaust passage.

  Moreover, in the above embodiment, although the direct heating type cooking apparatus was demonstrated, as shown in FIG.9 and FIG.10, it is a pot with which water is stored in the intermediate heating type cooking apparatus 1, for example, the liquid tank 3. As shown in FIG. The noodle machine 30 can also be configured in the same manner as the above-mentioned direct heating type cooking device, but the combustion gas passage 71 is provided in the liquid tank 3, so that the bottom of the liquid tank 3 is so hot. Must not. Therefore, in the case of the intermediate heating type cooking device 1, the heat shield frame 4 is configured by the front plate 401 and the side plates 402, 402 without providing the bottom plate, and the upper, rear and lower sides are opened. It is configured as a U-shaped frame body in plan view, and covers the front and side surfaces of the liquid tank 3 and the combustion chamber 62. Of course, a configuration in which a bottom plate is provided may be employed.

  As an embodiment of the present invention, the cooking device 1 provided with the heat shield frame 4 composed of the front plate 41, the side plates 42, 42 and the bottom plate 43 is shown in FIGS. The temperature of each part of the housing | casing 2 of the fryer 10 of 1st embodiment was measured. A glass fiber heat insulating material was installed between the front plate 41 and the side plate 42 and the liquid tank 3. As the fryer 10, a directly heated tabletop gas fryer DH-TGFL-40 manufactured by Taniko Co., Ltd. is used. As shown in FIG. 2, the heat shield frame 4 has a side plate 42 as a rectangle, a bottom plate 43, and The heat shield frame 4 was installed obliquely so that the back side of the fryer 10 was raised. The inclination angle between the horizontal plane and the upper end side 421 of the side plate 42 was 5 °.

  And 6 liters of salad oil was put into the liquid tank 3, the set temperature of the fryer 10 was set to 180 ° C., the gas burner was burned for 2 hours, and the average temperature and maximum temperature of each part shown in FIG. 11 were measured.

  As a comparative example, the heat shield frame was removed from the gas fryer used in the example, and the average temperature and the maximum temperature of each part shown in FIG. 11 for 2 hours were measured under the same conditions as in the example.

  The example and the comparative example are the same measurement points, and the measurement points are indicated by black dots in FIG. 11 and given a three-digit identification number. The results are shown in Table 1. Moreover, the difference of the average temperature of each part was computed, and the symbol of-(minus) was attached | subjected to the location where the temperature of an Example is higher.

  In the embodiment, the place where the average temperature is higher is several places of the back guard 22 and one place (416) on the back guard 22 side of the upper surface of the case 2. It can be seen that the temperature is lower in the example in the part.

  As a result, the heat cooking apparatus 1 of the present invention is not heated directly by the heat release from the combustion chamber 62, the liquid tank 3, and the combustion gas passage 64 to the housing 22, but is heated by the heat release. It is clear that the gas passes through the space 100, is sent to the back guard 22, and is discharged from the exhaust port 66. That is, it is clear that the heated air is discharged while heating the back guard 22 without heating the housing 2.

  The back guard 22 is installed on the back side of the cooking device 1, and a normal ventilation fan is provided above the exhaust port 66, so that the heated air from the exhaust port 66 and the heat radiation from the back guard 22 Since the air around the heated back guard is quickly discharged to the outside of the cooking chamber, heating the back guard 22 prevents the temperature of the outside air of the heating cooking apparatus 1 from becoming high due to heat radiation from the housing 2. In addition, there is no adverse effect on the improvement of the working environment using the cooking device 1.

  Further, since the back guard 22 is installed on the back side of the cooking device 1, it is away from the cook and there is no risk of burns because the cook does not come in contact with the work. It has been clarified that the casing 2 that is easy for a person to contact, the front surface and the front upper surface of the cooking device 1 are prevented from being directly heated by the heat shield frame and the temperature is lowered.

  The cooking device of the present invention has a liquid tank regardless of whether it is a direct heating type or an intermediate heating type, and various heating cooking apparatuses that heat water or oil in the liquid tank, for example, fryer or water for heating oil. Can be suitably used in a liquid heating cooking apparatus such as a rice bowl noodle device.
