Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a steam exhaust device for a cooking utensil such as a rice cooker, which is used for cooking while the cooking utensil is housed in a cabinet.

2. Description of the Related Art As shown in FIG. 6, in a conventional steam exhaust device for cooking utensils of this type, air sucked from an intake port 3 by an axial fan 2 provided above inside a cabinet 1 is passed through an intake passage 4.
The air then passes through the exhaust passage 6 and is discharged from the exhaust port 6. During this time, the steam generated in the rice cooker 41 and discharged from the steam port 42 is guided from the steam introduction lower to the steam passage 8, where it is exchanged with the air flowing through the exhaust passage 6 by heat dissipation plate 9 made of aluminum. The mixture chamber 10 is heated to a low temperature.
It is mixed with air and exhausted outside the cabinet 1.

At this time, the mixing chamber 10 widens toward the end in the flow direction,
Prevents backflow of steam. As a result, the steam generated from the rice cooker is exhausted outside the cabinet 1 as low-temperature air. Regarding the detection of steam, a thermal reed switch (TRS) 43 is provided at the bottom of the heat sink 9, which detects steam and rotates the axial fan 2 for a certain period of time using a timer (not shown). It had become.

Problems to be Solved by the Invention However, with such a structure, the rice cooker 41
Since the structure is such that the steam generated is drawn into the air flowing through the exhaust passage 6, if a cloth or apron is placed near the exhaust port 6, the air will flow back into the steam passage 8, causing the steam to This has the disadvantage that it is difficult for the steam to enter the lower steam introduction lower and the interior of the cabinet 1 is filled with the steam. Furthermore, when increasing the amount of air blown by the fan 2 in order to lower the temperature of the steam discharged from the exhaust port 6, the exhaust port 6 must also be increased in proportion to the amount of air blown, otherwise steam will not be sucked in from the steam introduction lower. It also had the disadvantage of becoming worse. Furthermore, in this case, there was also a drawback that unless the mixing chamber 1o was also made long, the temperature distribution of the hot air at the exhaust port 6 would not be uniform.

Furthermore, when steam is discharged from the exhaust port 6, the MW water exposed near the exhaust port 6 accumulates near the exhaust hole 6, and this exhaust port 6
It also had the disadvantage that it dripped onto the outside of the cabinet 1.

Furthermore, cooking=l! In cooking utensils such as rice cookers, for example, if you press the rice cook button (high heat) by mistake when the cooking menu S- is in a porridge state, that is, in a state where there is a lot of water compared to the rice, steam will be released. When generated, sol-like slime blows up from the steam port 42, and this slime enters the steam introduction lower, making cleaning difficult.

Furthermore, in the conventional configuration, the volume of the steam passage 8, mixing chamber 10, exhaust passage 6, etc. becomes large, so not only is it a challenge to make it compact, but also the wiring to the thermal reed switch 43 is difficult. , since these passages had to pass through Lt, there was also the drawback that the F9 vertical fee would be high.

Furthermore, in the conventional configuration, the thermal reed switch 4
After detecting steam in step 3, a timer was used to rotate the axial flow fan/2 for a certain period of time to discharge the steam. This is because the thermal reed switch 43 detects steam.
When the axial fan 2 is rotated, the thermal reed switch 43 is cooled by the air suctioned by this rotation, and the axial fan 2 is stopped.In order to prevent this, a timer is set. In this case, an axial fan is rotated for a certain period of time.
This has the disadvantage that the timer is expensive.

In addition, if the cooking utensils are not set in the correct position in the cabinet 1, or if the cooking utensils are used incorrectly, that is, the steam vent 4
2 and the suction lower do not match, the inside of the cabinet 1 is filled with steam coming out of the steam port 42, and the inside of the cabinet 1 becomes wet with steam. Further, Lτ, in the conventional configuration, the steam passage 8 and the mixing chamber 1
0. Parts such as the exhaust passage 5 and the rice cooker 41 are not separated inside the cabinet 1, so the cabinet notebook 1
The steam that filled the inside of the cabinet 1 spread to every corner of the inside of the cabinet 1 and corroded the core of the motor of the axial flow core/2.

An object of the present invention is to provide a steam exhaust device for cooking utensils that solves these problems.

Means for Solving the Problems In order to solve the above problems, the present invention provides a cabinet for storing cooking utensils that generate steam, and a fan case disposed in the cabinet above the cooking utensils. , a partition member installed in the cabinet to partition between the fan case and the cooking utensil,
A turbo fan driven by a motor is installed in the fan case, and the suction port of the fan case faces the partition member so as to face the steam exhaust portion of the cooking utensil, and the air outlet of the fan case It communicates with an exhaust port located outside the cabinet. In this case, the outlet of the fan case is inclined upwardly toward the outside of the cabinet in order to prevent water from dripping from the exhaust port into the steam container 1 within the outlet.

In addition, depending on the cooking utensil (1), there are cases where slop-like material outside the slit may blow out from the steam vent, so it is difficult for this to enter the turbo fan, and the steam generation from the cooking utensil is prevented. In order to provide a thermostat mounting part on the top surface inside the suction port, the present invention is configured so that the center of the impeller of the turbo fan and the center of the suction port of the fan case are closely aligned. There is.

Furthermore, in the present invention, thermostuff) is adjusted to When the turbo fan is rotated by detecting gas generation from the appliance and controlling the motor that drives the turbo fan, the thermostat is not cooled, and the steam is in contact with the thermostat while the turbo fan's impeller is turned. A dotted air guide guide with a cutout is provided near the thermostat in a part of the suction port of the fan case so that the air is drawn in and flows between both sides of the thermostat. ing.

In addition, if you use the cooking utensils in a position that is significantly shifted from their normal position, or if you take out the cooking utensils while steam is being generated, there is a problem that the steam will spread to every corner inside the cabinet and corrode the motor. , in the present invention,
A partition 9 member is installed inside the cabinet to partition between the fan case and the cooking utensils, and this partition member is provided with a ventilation hole that allows air sucked in from the intake port located outside the cabinet to pass through. The air that passes through this ventilation hole flows as if licking the top lid surface of the cooking unit 4 and enters the suction port of the fan case, but in this case,
The air cools the top lid surface and reduces the cooking performance of the cooking utensil. Therefore, in order to prevent the top lid surface of the cooking utensil from being cooled, in the present invention, air flow is provided at the bottom of the ventilation hole provided in the partition member. An air guide is provided so that the air is converted from the vertical direction to the lateral direction and guided to the inlet of the fan case.

In addition, if the 4A cooking utensil is used in a position that is slightly deviated from its normal position, that is, if the steam port of the cooking tool is deviated from the position of the suction port of the fan case, the leaked steam will be sucked into the suction port of the fan case. In the present invention, a substantially cylindrical cover surrounding the suction port is protruded downward from a partition member installed in the cabinet to partition the fan case and the cooking utensils. It is set up like this.

Function: With the above configuration, the air generated from the steam vents of cooking utensils stored in the cabinet is removed by operating the thermostat located near the suction port of the fan case with a turbo fan installed inside. , the motor works and makes the turbo fan 'J11@'. The turbo fan sucks in weather and air, which is agitated by the turbo fan's impeller and discharged to the outside through an exhaust port located at the tip of the fan case and outside the cabinet.

As a result, steam generated from the cooking utensils is exhausted to the outside of the cabinet as low-temperature air with a uniform heat distribution. In this case, put a dish towel on the exhaust port? Even if there is an apron, etc., the pressure will be higher due to the adoption of a turbo fan, so in this case, the exhaust and latches will only fall slightly.
It can prevent steam from entering the cabinet. Furthermore, in order to lower the temperature of the exhaust gas from the exhaust port, it is only necessary to increase the capacity of the turbo fan to increase the exhaust air volume, and there is no need to reduce the pressure at the exhaust port.

In addition, the condensed water at the outlet of the two-sided case will not drip from the exhaust outlet located outside the cabinet, and even if slime other than steam is spewed out, The impeller itself does not get dirty and is easy to clean because the fan case and the upper middle of the suction port do not match. The thermostat installed near the suction port detects the generation of steam and rotates the impeller, causing air to flow. A cylindrical air guide with a cutout is provided, so the thermostat can be cooled down and turned on and off.
No need to repeat FF.

Furthermore iA 3M a? Even if the amount of water that is stored in the D-key vignette is incomplete, the thermostat will only be able to detect the steam generation, and if the cooking utensils are generating steam,
Even when the cooking utensils are pulled out from inside the cabinet, a partition member is installed inside the cabinet to separate the fan case from the 2g cooking utensils, which prevents steam from spreading throughout the interior of the cabinet. This also prevents corrosion of motors, etc.

In addition, the air that is sucked in from the intake port located on the outside of the cabinet and passes through the ventilation hole provided in the partition member is converted from a vertical direction to a horizontal direction by an air guide provided at the bottom of the ventilation hole. Since the air is guided to the suction port of the fan case, the air does not locally cool the top lid surface of the cooking utensil.
! There will be no impact on performance.Example: An example of the present invention will be described below with reference to the attached drawings. In FIGS. 1 to 4, 11 is a cabinet that houses a rice cooker 13 that generates steam, and 12 is a countertop installed on the upper surface of the cabinet 11. 14

This air outlet 19 (exhaust outlet 20 located outside the cabinet 11)
It is inserted removably, and a V'i net or the like is permanently exposed at the exhaust port 20. 211t7y A suction port provided below the inlet 17, 22 is a thermostat whose sensitizing part protrudes inside the suction/inlet 21. 23 is a partition member installed in the cabinet 11, located above the I, +, rice cooker 13, and partitioning between the case 17 containing the turbo type 77716 and the rice cooker 5Z13. The partition member 23 includes the fan case 1.
The suction port 21 of the rice cooker 7 faces the steam port 14 of the rice cooker 13 so as to rotate oppositely to the steam port 14 of the rice cooker 13. 24 is a ventilation hole provided in the partition member 23. Reference numeral 26 denotes a panel provided on the upper front surface of the cabinet and throat 11, and the air outlet 19 of the fan case 17 is provided in this panel 25. 26 is an air intake port provided in the panel 26, and a mesh or the like is fixed to this air intake port 26.

If air is sucked in from the air inlet 26 provided in the panel 2 (τ) and passed through the ventilation hole 24, the air is transferred to the fan case 1.
7 to the suction port 21.

Next, the operation of the rice cooker steam discharging device configured as above will be explained.

First, rice and water are put into the rice cooker 13 and rice cooking is started. When the rice cooking process begins, a large amount of steam begins to spew out from the steam port 14 of the rice cooker 13. This steam will operate the thermostand 22 of the suction port 21. As a result, the motor 18 is driven and the impeller 1 of the turbo fan 16 is driven.
6 rotates, and air is sucked in from the suction port 21 of the fan case 17. In this case, as shown in FIG. 4, most of the air is sucked into the impeller 16 along the outer periphery of the wind guide 27 in a manner that traps the steam, and the steam is drawn into the impeller 16 along the outer periphery of the wind guide 27. Turn around the notch 27 and reach impeller '15. Due to this action 1c, cooling of the thermostat 22 is preventedb, so the thermostat 22 is turned on and off.
There will be no need to shake things up. In this case, the air is supplied from the suction port 26 of the fan case 17 through the ventilation hole 24 provided in the partition member 23, and is directed downward by the air guide 29 with a cross-sectional shape fixed to the lower part of the ventilation hole 24. The flow of air into the air will be converted laterally and will be sucked in through the suction port 21. Such an action can also prevent the cover 13a of the rice cooker 13 from being cooled by this air. Further, when the rice cooker 13 is pulled out from the cabinet 11 while steam is being generated, the steam from the steam port 14 hits the lower surface of the partition member 23, but does not directly spread to the motor 18, so corrosion of the motor 18 can be suppressed. .

Next, by raising the tip of the air outlet 19 of the fan case 17 toward the outside of the cabinet 11, i.e., tilting it upward, dew condensation can occur at the tip of the air outlet 19! Water does not drip or flow out from the exhaust port 20, and can be stored in a separate container.

In addition, the sticky substance other than the steam coming out of the steam port 14,
Since the center of the impeller 16 of the turbo fan 16 and the center of the suction port 21 of the fan case 17 are shifted from each other, the blown out sticky material is not aligned with the center of the suction port 21 of the fan case 17.
It only licks the inner upper surface and the air guiding guide 27, but does not enter the impeller 1S. Furthermore, as described above, by shifting the center of the impeller 1S and the upper middle of the suction port 21, the ceiling of the suction port 21 is inclined, and a thermostat is installed at this portion directly above the steam port 14. 22jz can be installed. As a result, eloquence 01
4. The air that spouts out from the air is controlled by a thermostat 2 installed on the ceiling of the suction port 210 located directly above the steam port 14.
2, the temperature of the heat sensitive part of the thermostat 22 rises, and the generation of steam is detected.

Furthermore, if the rice cooker 13 is not properly stored in the cabinet 11 and the position of the steam port 14 is slightly off from the suction port 21, the steam will hit the partition member 23 and the partition member 23. ') Diffusion of vapor toward the exit side of the cabinet 11 can be prevented by the surface extending downward from the lower surface. During this time, the steam enters the suction port 21 and activates the thermostat 22, so that the diffusion of steam into the interior of the cabinet 11 can be suppressed as much as possible.

In the above embodiments, a rice cooker has been described as a cooking utensil, but the present invention is not limited to this, and the present invention can also be applied to other cooking utensils, for example, a cooking device 4 that generates steam such as an automatic bread maker. Needless to say, it can be used quickly.

Effects of the Invention As is clear from the description of the above embodiments, according to Misfire 11JI, the steam generated from the steam port of the cooking utensils stored in the cabinet is discharged from the suction port of the fan case in which the turbo fan is installed inside. Part of the steam enters the fan case and is stirred by the impeller, condenses, and the rest passes through the fan case's outlet and is discharged from the exhaust port to the outside of the cabinet. , the air is uniformly cooled and has a low temperature. In addition, during use, due to the adoption of the exhaust port ((turbo type) 1) located outside the cabinet when a dish towel or apron is placed over the cabinet, the wind pressure is high, so in this case, the amount of exhaust air will drop slightly. Therefore, steam will not leak out from the suction port 21 of the fan case and fill the cabinet.Furthermore, if you want to increase the exhaust air volume, increase the rotation speed of the impeller or increase the size of the impeller of the turbo fan. It is possible.

Further, condensed water near the outlet of the fan case is discharged from the outlet toward the impeller side, but this can be received separately in a tank (not shown) or the like (14 configurations).

Furthermore, even if liquid other than steam is spewed out, the center of the turbo fan's impeller and the center of the suction port of the case are not aligned, so the impeller itself will not get dirty and cleaning will be easy. It's easy.

In addition, the steam generated from cooking utensils can be reliably detected using a thermostand, and the impeller of the turbo fan can be rotated until the steam generation stops without using a timer or the like, and the steam can be sucked in. , it can be served at low cost. Also, at this time, the air passing through the ventilation hole provided in the partition member from the intake port located on the outside of the cabinet is changed from vertical to horizontal by the air guide provided at the bottom of the ventilation hole. Since the air is converted and guided to the intake port of the fan case, the air
There is no need to locally cool the top lid surface of the cooking utensil, and as a result, there is no reduction in the cooking performance of the cooking utensil.

Not only can the thermostat detect steam generation even if the cooking utensils are not fully stored in the cabinet, but also when the cooking utensils are pulled out from inside the cabinet while the cooking utensils are generating steam. A partition member is installed inside the cabinet to separate the fan case and cooking utensils, which prevents steam from spreading throughout the interior of the cabinet, thereby preventing corrosion of the motor and cabinet. It is something that can be done.
