In addition, an openable / closable lid 3 is provided at the upper opening of the housing 2, and an inner lid 8 provided with a seal member 9 on the outer periphery of the lower surface is detachably attached to the lower surface of the lid 3. Yes. A steam discharge port 10 is provided on the upper surface of the lid body 7 and communicates with the inside of the heating container 4 through the steam passage 11.

  Reference numeral 20 denotes a steam processing apparatus, a steam recovery lid 21 detachably attached to the steam outlet 10 provided in the lid 3 of the heating cooker 1, a steam processing unit 23, and one end of the steam recovery lid 21. The other end is composed of a communication pipe 22 attached to the steam processing unit 23 at the other end.

Next, the steam processing apparatus 20 will be described in detail with reference to FIGS.
One end of a plurality of communication pipes 22 is connected to the steam recovery lid portion 21, and the other ends of the communication pipes 22 are respectively connected to a condensation pipe 27 of a heat exchanger 25 protruding from a case 24 of a steam processing unit 23 described later. It is connected.

  The steam processing unit 23 is one side of the upper part in a box-like case 24 (the front side is shown in the figure but is closed except for an air intake port of a sirocco fan 28 described later). In addition, a plurality of fins 26 having a width substantially equal to the width of the case 24 provided in the vertical direction and a plurality of holes (not shown) provided in the longitudinal direction of the fins 26 are inserted substantially perpendicularly to the upper end. A fin-and-tube heat exchanger 25 having a plurality of condensing tubes 27 protruding from the case 24 is provided.

  Reference numeral 28 denotes a sirocco fan disposed adjacent to the heat exchanger 25 so as to communicate with the outside through an air intake (not shown) provided in the case 24 and in parallel with the fins 26 of the heat exchanger 25. And it is installed so that a wind may flow in the longitudinal direction. And the wind which passed the heat exchanger 25 is discharged | emitted from the exhaust port 29 provided in case 24 in the other side of the sirocco fan 28. FIG.

  30 is a water drop collecting plate provided below the heat exchanger 25, and 31 is a drawer-type tank provided below the sirocco fan 28, and is housed in the case 24 detachably from the side surface of the case 24. Then, the water droplet collection plate 30 is installed to be inclined toward the tank 31 so that water that has been condensed and dropped by the heat exchanger 25 flows into the tank 31 to form a water channel.

Next, the operation of the present embodiment configured as described above will be described.
First, cooked rice and water are put into the heating container 5 and accommodated in the outer pot 4, and the lid 3 is closed.
At this time, the heating container 5 is sealed by the seal member 9 and the inner lid 8. When the induction heating coil 6 is energized and cooking is started, the heating container 5 generates heat and the food is gradually heated. As heating proceeds, steam is gradually generated from the heating container 5, and when the heating state further proceeds, the cooked product boils and steam is generated violently. The generated steam is pushed out by the pressure in the sealed heating container 5, led to the steam discharge port 10 from the steam passage 11 without leaking, and introduced into the steam recovery lid portion 21.

  The steam introduced into the steam recovery lid 21 is guided to the plurality of condensing pipes 27 of the heat exchanger 25 of the steam processing unit 23 through the plurality of communication pipes 22 connected thereto. Since the fins 26 are cooled by the air blown from the sirocco fan 28, the steam in the condensing tube 27 inserted through the fins 26 contacts the condensing tube 27, exchanges heat, and is condensed to return to water. The heat taken away at that time moves from the condenser tube 27 through the fins 26 and is discharged from the exhaust port 29 to the outside. Since the fins 26 are cooled by the air blown from the sirocco fan 28, the heat exchange operation is continuously performed.

  The water droplets condensed by the heat exchanger 25 and condensed are lowered along the condenser tube 27 and dropped onto the water droplet collecting plate 30, and are guided to the tank 31 and collected by the water channel formed thereby. When water accumulates in the tank 31, the tank 31 is pulled out and discarded.

According to the present embodiment configured as described above, steam generated during cooking from the heating cooker 1 can be condensed by the steam processing device 20 and recovered as water, so that the indoor humidity environment is deteriorated. There is nothing to do.
Moreover, since the steam processing apparatus 20 can be connected to the steam outlet 10 of the heating cooker 1, the steam generated during cooking can be condensed and collected without leaking into the room.
Further, in the heat exchanger 25 of the steam processing unit 23, fin-and-tube heat exchange in which steam generated during cooking is branched from the steam recovery lid portion 21 by a plurality of communication pipes 22 and introduced into a plurality of condensation pipes 27. Since it comprised with the container, compared with the case where heat exchange is carried out with one condensation pipe | tube, a vapor | steam can be condensed efficiently and can be collect | recovered.

Further, the fins 26 of the heat exchanger 25 of the steam processing unit 23 are cooled by the air sucked from the outside by the sirocco fan 28, and the wind flows in parallel with the fins 26, so that the pressure loss as an air path is small. Thus, the fins 6 can be cooled more efficiently and the steam can be recovered.
Further, since the condensing pipe 27 of the heat exchanger 25 is arranged so as to be substantially vertical when in use, the water condensed in the plurality of condensing pipes 27 falls as it is and is inclined toward the tank 31. Further, since the water droplet collection plate 30 guides the water to the tank 31, it is not necessary to form a water channel to the tank 31 individually for each condensing pipe 27, and the structure of the steam processing unit 23 can be simplified and made compact.

Further, since the tank 31 in which the water condensed by the heat exchanger 25 accumulates is detachable in a drawer type, the collected water can be easily discarded, and the tank 31 can be easily washed. 31 can always be kept hygienic.
Further, the exhaust gas that has passed through the fins 26 of the heat exchanger 25 is relatively hot because it takes heat away from the wind after heat exchange, that is, steam. Therefore, the user does not blow out from the side of the tank 31 to be taken in and out, so that the user does not feel uncomfortable.

[Embodiment 5]
11-13 is a diagram which shows the relationship between the rice cooking process of the heating cooker which concerns on Embodiment 5 of this invention, and the rotation speed of a sirocco fan, FIG. 11 is the rice cooking process of the rice cooker which concerns on Embodiment 2. FIG. 12, when the sirocco fan 28 is driven only in the boiling process, FIG. 12 is the same as when the sirocco fan 28 is driven in the boiling process and the steaming process, and FIG. 13 is also the input power to the heating source (induction heating coil 6) during cooking. The case where the sirocco fan 28 is driven according to the size of the sirocco fan 28 is shown. In each case, the horizontal axis represents the rice cooking process or input power, and the vertical axis represents the rotation speed of the sirocco fan 28.

  In FIG. 11, the preheating process of the horizontal rice cooking process is a process of sufficiently supplying water to the rice put in the heating container 5, and is generally controlled by the heating control unit 7 so that the inside of the heating container 5 becomes 50 to 60 ° C. Is done. The next boiling step is a step of cooking rice, and the heating vessel 5 is heated and controlled so that the rice and water are boiled, and is heated intermittently until there is almost no moisture inside (dry up). After that, the steaming process is entered and cooking is completed. This series of rice cooking processes is controlled by the heating control unit 7 based on the detection result of a temperature detecting means (not shown) for detecting the temperature of the heating container 5.

  Here, when the rotation speed of the sirocco fan 28 is controlled by the heating control unit 7, the sirocco fan 28 is not rotated because there is no need for vapor condensation in the preheating process and the steaming process in which almost no steam is generated from the heating container 5. The sirocco fan 28 is rotated only in a boiling process in which the contents boil vigorously to release the steam, and the steam is condensed and recovered stably and efficiently.

  In the case of FIG. 12, in the preheating process in which no steam is generated, the rotation of the sirocco fan 28 is set to a low rotation or stopped state, and in the boiling process in which steam is generated most intensely, the sirocco fan 28 is driven at a high rotational speed. The fins 26 of the exchanger 25 are cooled to recover the steam, and in the steaming process, the steam is recovered with the rotation speed of the sirocco fan 28 being medium. The reason why the sirocco fan 28 is rotated at a medium rotational speed in the steaming process is that the steam generated in the boiling process does not converge rapidly, and some steam may be generated in the steaming process.

In the case of FIG. 11 and FIG. 12 described above, the case where the rotation speed of the sirocco fan 28 is controlled in accordance with each step of rice cooking has been described. In the case of FIG. 13, the input power of the heating source (induction heating coil 6) The rotation of the sirocco fan 28 is controlled in accordance with the size of. In the case of the induction heating coil 6, the magnitude of the input power P to the heating source is about several tens W to 500W in the preheating process, 500W to 1000W or more in the boiling process, and several tens W to 500W in the steaming process. .
Since the food in the heating container 5 boils violently and generates a lot of steam when the input power P is large, a predetermined input power P ₁ (for example, 500 W) is set as a threshold value, and this input power P in high-speed rotation of the sirocco fan 28 is greater than _1, if P ₁ is less than controls to drive at low speed.

  As described above, in the case of FIG. 11, since the sirocco fan 28 is rotated only in the boiling process, the steam can be efficiently recovered in the boiling process in which a large amount of steam is generated. Further, since the sirocco fan 28 is not driven in processes other than the process of generating steam, wasteful power is not consumed, so that the energy saving effect can be enhanced. Furthermore, since the sirocco fan 28 rotates only in the boiling process, the noise generated from the sirocco fan 28 is only in the boiling process, so that a reduction in noise can be realized.

  Further, in the case of FIG. 12, since the rotation speed of the sirocco fan 28 is controlled in each step of cooking rice, the sirocco fan 28 is set at a medium rotation speed even in a process where a little steam is generated such as a steaming process. Since it is rotated, the steam can be recovered efficiently, and the steam is not released into the room. Furthermore, since the sirocco fan 28 is rotated in accordance with the amount of steam generated, the sirocco fan 28 is not rotated unnecessarily, thereby improving energy saving.

  In the case of FIG. 13, since the rotation speed of the sirocco fan 28 is controlled according to the magnitude of the input power of the heating source (induction heating coil 6), the input is made according to various amounts such as the amount of rice cooking and the rice cooking menu. Even if the electric power changes, the steam recovery performance does not deteriorate.

[Embodiment 6]
FIG. 14: is a block diagram of the heating cooker provided with the steam processing apparatus which concerns on Embodiment 6 of this invention. The same parts as those in the first and second embodiments are denoted by the same reference numerals, and description thereof is omitted.
Although Embodiment 5 demonstrated the case where the rotation of the sirocco fan 28 was controlled according to the rice cooking process of the heating cooker 1 or the magnitude | size of input electric power, as shown in FIG. A temperature detecting means 40 for detecting the temperature of the fin 26 is provided in the heat exchanger 25 of the steam processing unit 23, and the rotation of the sirocco fan 28 is controlled based on the detected temperature of the temperature detecting means 40.

Next, the operation of the present embodiment will be described. FIG. 15 is a diagram showing the temperature t of the fins 26 of the heat exchanger 25 on the horizontal axis and the rotational speed of the sirocco fan 28 on the vertical axis.
Rice cooking gradually proceeds in the heating container 5, steam is generated according to the rice cooking situation, and is sent to the heat exchanger 25 through the communication pipe 22. At this time, since the heat exchanger 25 performs a heat exchange action, the temperature of the fins 26 gradually increases. During this time, the temperature of the fin 26 detected by the temperature detection means 40 is sent to the heating control unit 7 and the sirocco fan 28 is driven at a low speed until the detected temperature reaches t ₁ , for example, 60 ° C.

When the rice is further cooked, the cooked product boils vigorously and a large amount of steam is generated, so that the temperature of the fins 26 further increases. Since the temperature of the steam sent to the heat exchanger 25 has reached approximately 100 ° C., the temperature of the fins 26 also rises accordingly.
When the temperature of the fin 26 detected by the temperature detection means 40 exceeds t ₁ (here, 60 ° C.), the sirocco fan 28 is controlled by the heating control unit 7 so as to rotate at a high rotational speed.

According to the present embodiment, the temperature of the fins 26 of the heat exchanger 25 is detected, and the rotation of the sirocco fan 28 is controlled according to the detected temperature, so that the amount of steam sent to the heat exchanger 25 is reduced. Accordingly, the rotational speed of the sirocco fan 28 can be controlled. For this reason, the sirocco fan 28 does not rotate unnecessarily and energy saving can be improved.
Further, when the amount of generated steam is small, noise is low because the sirocco fan 28 rotates at low speed, and when the amount of steam increases, the steam can be efficiently recovered.

[Embodiment 7]
FIG. 16 is an explanatory view of a heating cooker provided with a steam treatment apparatus according to Embodiment 7 of the present invention. In addition, the same code | symbol is attached | subjected to the same part as Embodiment 1, 2, and description is abbreviate | omitted.

When the steam processing unit 23 is not required or when the steam processing unit 23 is to be cleaned, it may be separated from the heating cooker 1 as shown in FIG.

According to the present embodiment, since there is one communication tube 22 disposed on the lower surface of the lid 3 of the heating cooker 1, the structure of the communication tube 22 and the lid 3 that accommodates the communication tube 22 is simplified. Therefore, the heating cooker 1 can be reduced in size.
