A pot body containing a heated object, at least a part of a bottom wall and a side wall placed on the upper part of the luminous body,
A hollow light diffuser that is housed in the pot and diffuses light in all directions is provided. During the heating operation, the pot is illuminated as if it were lit up, so it is confirmed that the pot is in the operating state It is easy to do.

At this time, if the hollow light diffuser is formed in a trumpet shape, it is easy to diffuse light traveling straight upward in all directions.

The present heating apparatus can be suitably used for a boiler, a water heater, a percolator, a drip-type coffee maker, and the like.

That is, while the object to be heated is water,
A component extraction material storage container arranged in the upper part of the pot body, and a trumpet-shaped foam collection tube arranged in the lower part of the pot,
A water pump comprising a water pump for communicating and connecting the foam collection tube and the material container for component extraction is provided to function as a percolator, and at least the foam collection tube of the water pump is hollow light diffusing. It is a body.

In this case, the hot water boiled by the heating means is
To raise the pumping pipe from the foaming pipe by the vapor pressure, reach the ingredient extraction container, and soak the coffee, brewing Chinese herbal medicine, healthy tea, etc. stored in the ingredient extraction container to extract the ingredients. While the water is being boiled, the luminous body emits light from at least the bottom of the pot body whose transparent bottom wall is transparent, and this light is diffused in all directions by the foam collection tube, so that the foam is collected. The appearance of boiling and air bubbles inside the tube is clearly shown through the wall surface of the foam collection tube, and the operating state of the heating device can be clearly seen.

Further, the hollow light diffuser may be configured to include not only a foam collecting tube but also a water pumping tube and a container for accommodating components for extracting components.

By the way, as the material of the hollow light diffuser, any material having a light diffusing function may be used, such as a material having a roughened surface or a surface cut, or a colored material. Although it is possible to use a resin made of milky white, it is preferable to use a milky synthetic resin.

That is, in the case of a milky white synthetic resin, the color of the illuminant is dimly and fantastically projected, and large and small bubbles, which rise, shine like a white illusion like a cloud, so that visibility is improved. In addition, an aesthetic effect can be achieved, and the heart of the user can be softened. Furthermore, since it is a synthetic resin, it is rich in heat insulation and can be made lightweight.Therefore, a temperature difference occurs between the inside and outside of the bubble collection tube formed in a trumpet shape, and the foam collection body becomes easy to float,
Relatively low-temperature hot water outside the foam collecting body easily flows into the foam collecting pipe from the lower portion, and the overall heating time can be reduced.

Further, as the luminous body, a halogen lamp also serving as a heating means can be suitably used.

That is, a halogen lamp has good thermal efficiency, and when it is desired to emit light of a color, by providing a colored light-transmitting filter, it is possible to easily produce a desired color.

Then, a green heat retention confirmation lamp 18e '
Is turned on automatically by the control unit 16 after the completion of cooking, or when the user presses the heat keeping button 18e.

When the temperature sensor 13 detects an abnormally high temperature state of the pot 2 or a state where the temperature does not change with time, the start / cancel button 18a is turned off when there is a shortage of water or an abnormality without the pot 2. I am trying to become. In FIG. 1, reference numeral 17 denotes a thermal fuse.

Next, the pot 2 will be described with reference to FIGS.

The pot 2 is provided with a spout 19 at an upper facing position.
And a transparent cylindrical pot made of heat-resistant glass provided with a handle 20, and an outer lid 22 provided with an endoscope dome 21 made of glass at the upper center. On the inner surface of the outer lid 22, a healthy tea pack 23 containing, for example, oolong tea, rooibos tea, gymnema tea, tochu tea, ashita leaf tea, havana tea, and the like, which are examples of the stewed material that floats during the stew.
Is provided from above.

In the pot 2, a large-diameter bubble collection tube 25 in the shape of a downward trumpet disposed at the lower part of the pot and a component extraction material storage container disposed at the upper part of the pot are provided in the health tea pack 23. The boiled dish 26 for boiling tea, the foaming tube 25 and the boiled dish 26 are connected to each other, and the water boiled by the halogen lamp 10 in the lower part of the pot 2 is supplied to the boiled dish 26 to provide the healthy tea pack 23. A water pump C comprising a water pipe 27 for immersing the water is provided. The water pump C is lightweight, has good heat insulation properties, has a heat-resistant temperature of 149 to 171 ° C., and further has an inorganic material. It is integrally formed of polysulfone resin having good chemical resistance to acid, alkali, and salt solutions.

Each of the members 25 to 27 of the water pump C has a translucent milky white color, and serves as a hollow light diffuser a for diffusing light from the transparent pot 2 and the halogen lamp 10 that has passed through water in all directions. As shown in FIG. 2, the light-up mechanism B functions as a main part of the present invention together with the halogen lamp 10. In this embodiment, the entire pump C is configured to function as the hollow light diffuser a. However, the hollow light diffuser a can function sufficiently only with the bubble collection tube 25 alone.

At the lower edge of the foam collection tube 25, there are formed four notches 25a through which water enters and exits between the lower part of the pot and the inside of the foam collection tube 25 at every 90 °.

Further, since the foaming tube 25 is formed of a polysulfone resin having good heat insulating properties as described above, the water in the lower part of the pot is heated by the high temperature water in the boiling foaming tube 25 and the boiled dish. The heat can be shut off from the low-temperature decoction solution (boiled liquid) that has dropped from the side 26, and since it is lightweight, it is easy to float up, and external hot water that is relatively low in temperature compared to the inside of the same bubble collection tube 25 Easy to introduce inside
The overall boiling time can be reduced, and the heating efficiency is good.

The pumping pipe 27 raises and supplies the boiling water to the boiled dish 26 from a drain port 27a formed at the upper end of the pumping pipe 27 while causing the convection of the boiling water to rise in the pipe. It is a pipe body adjusted to a thickness that allows the pumping pipe 27 to have an inner diameter of 5 to 20 m.
m, preferably 10 to 15 mm. In this embodiment, it is set to 10 mm.

The reason for setting such a range is that the pumping pipe 2
When the inner diameter of 7 is less than 5 mm, the water pipe 27 becomes too thin, and the speed of rising the boiling water to the boiled dish 26 increases,
Part of the boiling water rising in the pumping pipe 27 is supplied to the boiled dish 26 without convection in the pipe returning to the foam collection pipe 25,
As a result, the decoction of the healthy tea pack 23 cannot be sufficiently performed.
7 is too thick, and boiling water containing bubbles heated at the lower part of the pot is supplied to the inlet 2 of the pumping pipe 27 by the foam collection pipe 25.
Even if it is collected to 7b, the rising power of the boiling water containing air bubbles cannot lift the pumping tube 27 and the healthy tea pack 23 cannot be boiled.

The boiled dish 26 is a dish member having a gentle trumpet shape at the lower part, and the bottom surface of the central part thereof is connected to the drain port 27 a formed at the upper end of the pumping pipe 27 so as to be flush with each other. ing.

At the bottom of the boiled dish 26, a lower filter 28 serving as a placing member for the health tea pack 23 and serving as a strainer for unboiled food such as healthy tea.
Is installed. That is, the healthy tea pack 23
It is stored in the space between the upper and lower filters 24 and 28.

A plurality of overflow portions 29 for returning boiled water to the lower portion of the pot 2 at predetermined angles are formed on the upper peripheral surface of the boiled dish 26. Flange 26 mounted on upper peripheral edge of 2
a is formed.

Here, a method of using the boiler A of the present embodiment will be described.

First, the foam collecting tube 25, the water pumping tube 27 and the boiled dish 26 are placed on the heating plate 7 from the pot mounting opening 3 a of the heating table 1.
Is placed on the pot 2 containing. Next, the outer lid 22 is opened, and the health tea pack 23 is boiled and the lower filter 28 of the dish 26 is removed.
Place on top. When the outer lid 22 is closed, the health tea pack 23
Are arranged in the space between the upper and lower filters 24 and 28.

Then, any one of the first to third setting buttons 18b, 18c, 18d shown in FIG. 4 is pressed in accordance with the brewing time of the healthy tea in the healthy tea pack 23 (normal healthy tea brewing). In this case, the first setting button 18b for 5 minutes is used). As a result, one of the first to third setting confirmation lamps 18b ', 18c', and 18d 'is turned on (the first setting confirmation lamp 18b' is usually used).

Next, the start / cancel button 1 of the heating table 1
When 8a is pressed, a short alarm sounds and the red LE
The ON / OFF confirmation lamp 18a 'of the D lamp is turned on, and the control unit 16 supplies electricity to the halogen lamp 10 to start heating water accumulated in the lower portion of the pot 2, and the light emission of the halogen lamp 10 causes The milky members 25 to 27 forming the above-mentioned hollow light diffuser diffuse the light in all directions, so that a fantastic luminescent color appears as a whole (FIG. 2).

As shown in FIG. 3, when the water in the pot 2 starts to boil, the boiling water containing air bubbles is collected at the upper center by a downwardly trumpet-shaped bubble collecting tube 25 and rises up the pumping tube 27. Is supplied to the boiled dish 26.

Since the inner diameter of the water pipe 27 is 10 mm, which is larger than the inner diameter of the water pipe of the percolator for boiling coffee or the like, the rising power of the boiling water collected by the foaming pipe 25 makes the water pipe of the percolator thin. As shown in the figure, the boiling water cannot rise to the dish 26, and in the pumping tube 27, a part of the boiling water returns to the foaming tube 25, causing convection in the tube. Plate 26
Go up to In the boiled dish 26, the temperature is lowered to the simmering temperature by the outside air, or if the temperature is too low, the temperature is raised again by the rise of boiling water from the water pumping pipe 27. As a result, the simmering temperature is always maintained. ,
The boiling water rising to the boiled dish 26 little by little is stored, and the healthy tea pack 23 in the boiled dish 26 is sufficiently immersed,
It is boiled slowly for a predetermined time.

At this time, the overflowing decoction water falls from the overflow section 29 into the lower part of the pot,
Some of the decoction water is multiplied by the convection of the boiling water in the pipe of the water pumping pipe 27 and goes down the water pumping pipe 27 to convert the inside of the lower part of the pot into brewed water.

As described above, the water in the pot 2 during the decoction is lit up from below by the halogen lamp 10 housed in the lower part of the heating table 1 as shown in FIG. Through the transparent pot 2, boiling water containing a large number of air bubbles collected by the translucent milky white foam collecting tube 25 is boiled out of the water pumping tube 27 and the dish 2.
6 can be surely visually recognized while enjoying the state in which the healthy tea pack 23 is boiled out. In particular, the large and small bubbles ascending shine as white illusions like clouds, and their movement and size can be clearly confirmed, and the user's mind can be relaxed (FIG. 3). Further, since the water pump C is translucent milky white, if the halogen lamp 10 is white light, it is easy to recognize the color of the boiled decoction water.

At the completion of the infusion, after the ON / OFF confirmation lamp 18a 'blinks and the alarm continues to beep for 10 seconds with a short sound, the confirmation lamp 18a' is turned off together with the first setting confirmation lamp 18b '.

After completion of the decoction, the green heat retention confirmation lamp 18e 'is automatically turned on by the control unit 16, and the temperature is lowered to a predetermined temperature.

At an appropriate time, the user can press the heat retention button 18e to bring the temperature into the heat retention state. Also,
When the temperature sensor 13 detects an abnormally high temperature state of the pot 2 or a state where there is no change in temperature over time, the start / cancel button 18 is pressed when there is a shortage of water or an abnormality without the pot.
a is set to OFF.

Thereafter, the outer lid 22 is opened to take out the stored foam collection tube 25, the water pumping tube 27, and the boiled dish 26, the handle 20 is tilted, the pot 2 is tilted, and the decoction solution is poured from the spout 19 into a cup. Pour and drink it.

The hollow light diffuser a composed of the foam collection tube 25, the water pumping tube 27, and the boiled dish 26 can be detachably attached to the outer lid 22, and can be taken out at the same time as the outer lid 22 is opened. it can.

As described above, the boiler A of the present embodiment is characterized in that boiling water containing a large number of bubbles collected by the translucent milky white foam collection tube 25 from the outside through the transparent pot 2 is
The state of being pumped out from the pumping pipe 27 to the boiled dish 26 and boiled out of the to-be-boiled material can be clearly projected by the light from the halogen lamp 10, the visibility is improved, and from a position away from the boiler A. But you can see how it works.

Further, the inside diameter of the pumping pipe 27 is set to a size that allows the water boiled by the halogen lamp 10 in the lower part of the pot 2 to be supplied to the boiling dish 26 and stored therein, so that the boiling water is gradually discharged from the pumping pipe 27 to the surface area. Is pumped up and stored in a large boiled dish 26, and the rising boiling water is cooled down to the simmering temperature by the outside air, whereby the health tea pack 23 in the boiled dish 26 which has been sufficiently immersed is automatically and carefully taken for a predetermined time. And can be boiled out.

The boiled liquid is collected in the lower part of the pot, and the boiled-cooked healthy tea pack 23 remains in the boiled dish 26 above it. After boiled, the healthy tea pack 23 and the boiled liquid are naturally separated and boiled. Excessive boiling due to residual heat of the liquid can be avoided.

Since the lower filter 28 is provided inside the stewed dish 26, the stewed material is the health tea pack 23.
In addition, for example, even rose leaves and powdered materials do not flow out of the drainage port 27a of the water pump pipe 27 into the pot 2, so that they can be boiled without being packed in a pack.

Further, since an upper filter 24 is provided on the inner surface of the outer lid 22 so as to press down the healthy tea pack 23 floating during boiling out from above, for example, the healthy tea pack 23 is packed by a bag-like filter. Even if the leaves and granules are not leaked, they do not flow out of the overflow section 29 into the pot 2 and the health tea pack 2
In the case of 3, the state is held by the upper and lower filters 24 and 28, and the pressure of the water jetted from the pumping pipe 27 of the boiling water directly acts to enhance the boiling effect.

Further, since the drain port 27a formed at the upper end of the pumping pipe 27 is connected to the bottom surface of the cooking dish 26, relatively high-temperature pumping water can be supplied into the cooking dish 26 and relatively high. Since the length of the pumping pipe 27 becomes shorter,
The boiling of the healthy tea pack 23 can be started in a short time.

Next, since an overflow section 29 for returning boiled water to the lower part of the pot 2 is provided above the boiled dish 26, the boiled liquid of the healthy tea pack 23 in the boiled dish 26 is
In accordance with the rising amount of the boiling water from the water pipe 27 to the boiled dish 26, the water can be dropped from the overflow section 26 to the lower part of the pot 2 by an appropriate amount and returned.
In 6, the healthy tea pack 23 can be boiled well with moderate heat.

By the way, in this embodiment, the luminous body is
Although the halogen lamp 10 which also serves as a heating means is employed,
As shown in FIG. 5, when an auxiliary lamp D is separately provided, and the heating is completed and the halogen lamp 10 is turned off, the auxiliary lamp D may emit light in a different color from that during heating or blink. it can. With such a configuration, even when the cooking is completed, it is possible to recognize that the heating plate 7 and the pot 2 are still in a high temperature state, and there is no risk of accidental burns.

In place of the halogen lamp 10 described above, other heating means that does not emit light may be used. In this case, a light-emitting body similar to the auxiliary lamp D is separately provided, and even in this case, a plurality of light-emitting elements having different emission colors are provided during and after the heating,
Alternatively, even with a single light emitting body, it is preferable that the state of heating and the end of heating can be visually recognized by changing between lighting and blinking.

Although the present invention has been described with reference to the boiler A, the present invention can also be applied to a water heater, a percolator, a drip coffee machine, and the like.
