6 to 10, the steam generating means 43 includes a boiler main body 43a that is open at the top and has a steam generation chamber 103 inside, and a flat plate formed of a steel plate that closes the upper opening of the boiler main body 43a. The boiler lid part 43b has a shape. The boiler main body part 43a is formed by aluminum die-casting and is shaped like a horizontally long container. The steam generation chamber 103 formed into a container shape is formed at the front of the boiler room equipped with the spout 44 (boiler room front upper part 43d, boiler room front lower part 43e, boiler room inclined part 43f) and at the rear of the boiler room front. the boiler room rear surface 43h, the boiler bottom surface 43g formed at the front surface of the boiler room and the bottom of the boiler room rear surface, and the left side surface of the boiler room located on the left side of the steam generating means 43 when viewed from the spout 44 side (FIG. 10). 43j, and a boiler room right side 43k located on the right side.

The front surface of the boiler room includes an upper portion 43d of the front surface of the boiler room provided with the spout 44, a lower portion 43e of the front surface of the boiler room connected to the bottom surface 43g of the boiler room, and a lower portion 43e of the front surface of the boiler room that expands outward toward the upper portion 43d of the front surface of the boiler room. A boiler room inclined portion 43f is formed to be inclined as shown in FIG.

A water supply port 104 for supplying water from the water tank 42 into the steam generation chamber 103 is provided above the right side surface 43k of the boiler room, and the water supply port 104 is provided above the spout 44. It is located. A thermostat 106 is provided below the water supply port 104 to prevent abnormal heating of the boiler main body 43a due to dry firing or the like. The thermostat 106 is fixed to the right side surface 43k of the boiler room with a screw 201. A pipe 40 shown in FIG. 5 is connected to the water supply port 104.

A boiler heating means 89 for heating the water supplied to the steam generation chamber 103 is provided below the boiler chamber bottom surface 43g. The boiler heating means 89 uses, for example, a sheathed heater and has a U-shape. The boiler heating means 89 includes a heat generating part 89a and a non-heat generating part 89b, which are embedded and integrally formed below the boiler main body part 43a. The heat-generating portion 89a is located in a straight U-shaped portion and is located below the bottom surface 43g of the boiler room, and the non-heat-generating portion 89b is located in a curved portion bent into a U-shape. The curved portion of the boiler heating means 89 is located at a protrusion 43p formed to protrude downward from the boiler main body 43a. The ends of the boiler heating means 89 protrude from the right side of the boiler room 43k and the right side of the protrusion 43p, respectively, and are connected to a power source. The direction in which the boiler heating means 89 is connected to the power source matches the direction in which the water supply port 104 is connected to the pipe 40.

By configuring the boiler heating means 89 of the first embodiment as described above, the heat generated in the heat generating part 89a is efficiently transmitted to each heating wall, heating the water in the steam generation chamber 103, and heating the water in the steam generation chamber 103. By using the U-shaped curved portion that makes a small contribution to heating as the non-heat generating portion 89b, leakage of heat from the U-shaped curved portion can be suppressed and energy saving can be improved.

A temperature detection means b88 for detecting the temperature of the steam generation means 43 is provided on the left side surface 43j of the boiler room, and is fixed with a screw 202.

A sealing member 43s is disposed between the boiler main body 43a and the boiler lid 43b to prevent the steam generated in the steam generation chamber 103 from leaking. The boiler lid portion 43b is fixed to the boiler main body portion 43a with a screw 203 via a seal member 43s. The seal member 43s can be eliminated by increasing the number of screws 203.

The boiler lid portion 43b is formed with a lid recess 43m that is recessed downward from the flat surface, and a lid protrusion 43n that projects upward from the lid recess 43m. Although the four lid protrusions 43n of the first embodiment are circular, the number of lid protrusions 43n is not limited to four, and for example, one continuous rectangular shape may be formed.

The water injected from the water supply port 104 is heated on the bottom surface 43g of the boiler room forming the steam generation chamber 103 and vaporized into steam, and is then passed through the water vapor generation means 43 through the spout 44 provided at the upper part 43d of the front surface of the boiler room. Water vapor is discharged to the outside.

Embodiment 1 has the above configuration, and next, the steam generating operation of the steam generating means 43 will be explained.

Note that high-frequency heating cooking using the magnetron 33, grill cooking using the grill heating means 12, hot air oven heating cooking using the hot air unit 11, and steam cooking using steam generated by heating water are well known. Explanations regarding the dishes will be omitted.

First, water is poured into the water tank 42 before heating. Next, when power is applied to the boiler heating means 89, heating of the steam generating means 43 is started. The control means (not shown) controls the boiler heating means 89 and the pump means 87 based on the temperature of the steam generation means 43 detected by the temperature detection means b88.

When the temperature of the steam generating means 43 detected by the temperature detecting means b88 reaches a predetermined temperature or higher (temperature at which water can be heated to steam, here 130° C.), the pump means 87 is driven, and the pipe 45 from the water tank 42 is driven. , 40, water is supplied from the water supply port 104 of the boiler main body 43a to the steam generation chamber 103.

The water supplied to the steam generation chamber 103 is vaporized (vaporized) by obtaining heat of vaporization from the bottom surface 43g of the boiler chamber heated by the boiler heating means 89. The vaporized water vapor becomes lighter in volume than the surrounding air and floats upward. As shown by the arrow in FIG. 9, part of the surfaced water vapor is ejected from the spout 44 and flows into the heating chamber that houses the heated part (steam path 310), and the rest flows upward into the steam generation chamber 103. (Steam path 311) reaches the boiler lid portion 43b.

In the steam generation chamber 103 of Example 1, the closer it is to the boiler heating means 89, the higher the temperature is, and the further away from the boiler heating means 89, the lower the temperature is. That is, the temperature of the boiler room bottom surface 43g is high, and the temperature of the boiler lid portion 43b is low.

The steam flowing through the steam path 311 drifts near the back surface (lower surface) of the boiler lid 43b, and as time passes, the temperature decreases and liquefies, and returns to the bottom surface 43g of the boiler room again, gaining heat of vaporization and becoming vaporized. do. Water droplets adhere to the back surface (lower surface) of the boiler lid portion 43b due to liquefaction of water vapor. In the first embodiment, a lid convex portion 43n is formed on the boiler lid portion 43b. The lid convex portion 43n has a shape recessed from the back surface (lower surface) of the boiler lid portion 43b when viewed from the steam generation chamber 103 side. In the first embodiment, the structure is such that water droplets accumulate on the back surface of the lid protrusion 43n, and the water droplets that can no longer be held on the back surface of the lid protrusion 43n return to the bottom surface 43g of the boiler chamber. Furthermore, in the first embodiment, the boiler room inclined portion 43f is formed at the lower part of the spout 44, so that water droplets are encouraged to return to the boiler room bottom surface 43g.

When water is heated, the gas dissolved in the water is released, creating bubbles. The water supplied to the steam generation chamber is heated by the boiler heating means, thereby generating a plurality of bubbles within the steam generation chamber. The generated plurality of bubbles repeats bursting and joining of adjacent bubbles, and rises up the wall surface of the steam generation chamber like a string of beads, reaches the spout, and flows into the heating chamber where cooking is performed. Since this could cause overflow, the amount of water supplied to the steam generation chamber was limited. For this reason, there was a problem in that the amount of steam generated for use in cooking was reduced. A configuration for solving this problem will be explained using FIG. 11.

FIG. 11 is a sectional view of the steam generating means 43 according to the first embodiment of the present invention. FIG. 12 is a sectional view of a steam generating means according to a comparative example.

The boiler room front upper part 43d is arranged such that the distance between the boiler room front upper part 43d and the boiler room rear face 43h is longer than the distance between the boiler room front lower part 43e and the boiler room rear face 43h. A boiler room inclined portion 43f is provided below the spout 44 and between the boiler room front upper part 43d and the boiler room front lower part 43e. That is, in the boiler room inclined part 43f, the distance connecting the boiler room inclined part 43f and the boiler room rear surface 43h gradually becomes larger than the distance connecting the boiler room front lower part 43e and the boiler room rear surface 43h. .

In FIG. 11, in the steam generation chamber 103, water in the steam generation chamber 103 is boiled by heating by the boiler heating means 89, and bubbles 300 are generated. Some of the bubbles 301 are vaporized.

The bubbles 300 generated between the lower front surface 43e of the boiler room and the rear surface 43h of the boiler room repeatedly burst and combine to move up the steam generation chamber 103, but when they reach the sloped part 43f of the boiler room, the space is expanded. The combination of adjacent bubbles 300 is suppressed, and the upward movement of bubbles 300 in the steam generation chamber 103 is suppressed. As a result, the air bubbles 300 do not reach the ejection port 44, so that overflowing from the ejection port 44 into the heating chamber 28 can be suppressed.

FIG. 12 is a comparative example. In the comparative example, an ejection passage 44a that is linearly connected to the ejection port 44 is formed in the steam generation chamber 103, and this ejection passage 44a is connected to the front lower part 43e of the boiler room.

In the case shown in FIG. 12, the bubbles 300 generated between the lower front surface 43e of the boiler room and the rear surface 43h of the boiler room repeat bursting and combining, ascend the steam generation chamber 103, and reach the ejection passage 44a. The bubbles 300 that have reached the ejection passage 44a flow from the ejection port 44 to the heating chamber where cooking is performed. In this way, in the structure shown in FIG. 12, there is no place where the space is expanded, so there is a possibility that the air will spill into the heating chamber 28.

On the other hand, according to the structure of Example 1 (FIG. 11), it is possible to suppress the air bubbles 300 from reaching the ejection port 44, and it is possible to suppress the air bubbles 300 from flowing into the heating chamber 28.

According to the first embodiment, the boiler room inclined portion 43f that expands the space of the steam generation chamber 103 is provided below the spout 44, thereby suppressing overflow from the spout 44 into the heating chamber 28. Accordingly, it is possible to provide a cooking device with improved steam cooking performance.

Next, a second embodiment of the present invention will be described using FIG. 13. FIG. 12 is a sectional view of the steam generating means 43 according to the second embodiment of the present invention. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed explanation thereof will be omitted.

In the second embodiment, instead of the boiler room inclined part 43f described in the first embodiment, a boiler room step part 43i is provided. The boiler room stepped portion 43i is formed between the boiler room front upper part 43d and the boiler room front lower part 43e, and is located below the spout 44.

The boiler room front upper part 43d is arranged such that the distance between the boiler room front upper part 43d and the boiler room rear face 43h is longer than the distance between the boiler room front lower part 43e and the boiler room rear face 43h. A boiler room stepped portion 43i is provided below the spout 44 and between the boiler room front upper part 43d and the boiler room front lower part 43e.

The bubbles 300 generated between the lower front surface 43e of the boiler room and the rear surface 43h of the boiler room repeatedly burst and combine to ascend the steam generation chamber 103, but when they reach the stepped portion 43i of the boiler room, the space is expanded. The combination of adjacent bubbles 300 is suppressed, and the bubbles 300 can be suppressed from rising in the steam generation chamber 103.

According to the second embodiment, it is possible to suppress the air bubbles 300 from reaching the spout 44, to suppress the air bubbles from blowing into the heating chamber, and to provide a cooking device that improves the performance of steam cooking. be able to.
