Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a thermal insulation basket used to store bread, fried foods, etc. and keep them warm. This device stores and holds a heat-insulating pan, and has a humidifying water reservoir provided at the bottom of a container-shaped main body that communicates with the space above the heat-insulating pan.

(Prior art) As this type of thermal basket, for example, Jikaisho's
There is one shown in Publication No. 56-94619. In this thermal insulation basket, the steam generated in the humidifying water storage section is caused to flow out from the annular passage formed by the spacer protrusion between the container-shaped main body and the thermal insulation pan, and the steam is stored in the thermal insulation pan by the steam. It humidifies the insulating material.

(Problem to be solved by the invention) However, in the above-mentioned conventional heating basket, the steam from the humidifying water storage section flows almost unrestrictedly onto the heating pan from the annular passage between the container-shaped body and the heating pan. In addition, even if there is uneven generation or presence of steam in the humidifying water storage section, it will flow directly onto the heat-insulating pan.

Therefore, bread products are locally humidified,
Excess steam may condense on the lid, causing water droplets to drip onto the bread or thermal pan, causing the bread to absorb excessive moisture or water locally.
Appropriate heat retention cannot be expected.

Therefore, the present invention solves the above problems and also
To provide a heat-retaining basket capable of appropriately keeping bread items warm even in the case where appropriate humidity must be maintained uniformly.

(Means for Solving the Problems) In order to achieve the above object, this invention stores and holds a heat-insulating pan in a container-shaped body having a bottom portion provided with a heater, and a heat-insulating pan is placed in the bottom of the container-shaped body. The heat-insulating basket is provided with a humidifying water storage part communicating with the upper space, and is characterized in that a small steam passage leading from the humidifying water storing part to the space above the heat-insulating pan is arranged around the heat-insulating pan.

(Function) The water in the humidifying water storage section is heated by the heater and vaporized. This steam tries to diffuse from the container mold body to the space above the heating pan, but it is restricted by the small steam passages arranged around the heating pan, and is collected inside the container mold body and is uniformized from each steam passage. It is evenly distributed into the space above the insulation pan and flows out appropriately. As a result, the atmosphere above the heat-insulating pan is evenly and moderately humidified from above, which acts on the objects to be kept warm that are placed in the heat-insulating pan.

(Embodiment) To explain the first embodiment shown in FIGS. 1 to 4, a container-shaped main body 1 is formed hollow from a metal plate. A surface heater 3 is attached to the back surface of the inner bottom 2 of the main body 1, and is heated within a temperature control range by a thermostat 4. The upper opening 5 of the main body 1 is closed with a lid 6 made of synthetic resin or the like, and the bread, fried foods, etc. stored in the main body 1 are kept warm in a closed space by heating with the heater 3. Handles 7 on both ends of main body 1
However, handbag handles 8 that can be raised and lowered freely are attached to both sides.

An annular step 9 is formed on the inner periphery of the opening 5 of the main body 1, and by receiving the outer periphery flange 11 of the insulation pan 10 on this step 9, the insulation pan 1
0, the bottom part 10a of the thermal pan 10 is lifted from the bottom part 2 of the main body, and the bottom-to-bottom heat influence suppressing part 1
2 is formed. Handle pieces 13 are provided on both sides of the flange 11 and extend outward, and these handle pieces 13 face the outer periphery of the opening 5 from the rim opening 14 that is formed flush with the step 9 of the main body opening 5. , thermal bread 1
0 to and from the main body 1 and facilitates its attachment and detachment.

The heat-retaining pan 10 is shaped like a container, and even when storing bread and fried food to keep them warm, it can well receive the scraps that fall from the bread and fried food and prevent them from spilling into the main body 1. It can also store soup and keep it warm. The bottom part 10a is floated from the bottom part 2 of the main body where the temperature decreases due to the installation of the heater 3, and direct heat influence from this inner bottom part 2 is suppressed. , heat transfer through detours such as the insulation pan 11, and heat radiation from the inner wall of the main body 1 to the entire outer surface of the insulation pan 10, the temperature is almost uniformly raised to an appropriate temperature without local heating etc. To uniformly and appropriately keep the heat of an object to be kept warm through an air layer around it without causing the contact part to become excessively dry, solidified or discolored by contact with the object to be kept warm.

Even with the lid 6 attached, the object to be kept warm gradually loses moisture while being kept warm, which may be inconvenient when keeping bread or the like that must be kept at an appropriate humidity.
Therefore, it is recommended to perform humidification to prevent dryness.

This humidification can be performed by using the steam that is evaporated by heating the heater 3 when humidifying water is stored in the inner bottom 2 of the main body 1 as a humidifying water reservoir 15. This steam is generated under the insulation pan 10,
Although steam tends to emanate from the inner bottom of the main body 1 into the space above the heat-insulating pan 10, it is evenly dispersed and appropriately flows out from the ventilation holes (steam passages) 16 provided in the peripheral wall of the heat-insulating pan 10 into the space above the heat-insulating pan 10. As a result, the atmosphere above the thermal insulation pan 10 is evenly and moderately humidified from above, so the thermal insulation pan 10 has the problem of stickiness of the heated object, which occurs when steam is discharged from a conventional grating board or a wide space. Bread can be kept warm at the optimum humidity. In addition, as shown by the imaginary line in FIG. 4, the lid 6 may be attached to the mouth portion 5 of the main body 1 away from the heat-insulating pan 10.

The second embodiment shown in FIG. 5 shows a case where a ventilation hole 16 is formed in the flange 11 of the heat insulation pan 10,
The steam from below the heating pan 10 escapes upward, is directed downward by the lid 6, spreads into the upper air of the entire object to be kept warm on the insulation pan 10, and reaches the entire object to be kept warm, as described above. , it is difficult for the local parts of the object to be kept warm to become sticky.

As in the third embodiment shown in FIG. 6, a ventilation gap (steam passage) 17 is formed between the unevenness formed on the upper surface of the stepped portion 9 and the insulation pan flange 11 that is received thereon.
Even if it is formed, humidification with the same characteristics as in each of the above embodiments can be performed. This ventilation gap 17 also allows condensation to occur on the inner surface of the lid 6 due to various conditions such as the outside temperature and the material of the lid 6. I am trying to have it sent back to .

In addition, the inner bottom part 2 of the main body 1 is made of stainless steel, and the insulation pan 10 is made of aluminum.
Damage to the main body 1 side due to contact between the two is prevented, but
The more the insulation pan 10 is made of a material with lower thermal conductivity, such as stainless steel or ceramic, the more advantageous it is in terms of suppressing the influence of heat from the bottom 2 inside the main body. In this case, it is also effective to make the inner bottom part 2 of the main body made of aluminum or the like having good thermal conductivity to improve heat transmission around the heat retention area and improve thermal efficiency and uniform heat retention.

(Effects) According to the present invention, a heat-insulating pan is housed and held in a container-shaped body having a bottom provided with a heater, and a humidifying water reservoir is provided at the bottom of the container-shaped body and communicating with the space above the warming pan. In the basket, a small steam passage leading from the humidifying water storage part to the space above the heating pan is arranged around the heating pan, so that the steam vaporized from the humidifying water storage part is transferred to the small steam passage arranged around the heating pan. The steam is restricted by the passages and is uniformized inside the container-shaped body, but is evenly distributed from each passage to the space above the heating pan and flows out appropriately. As a result, the atmosphere above the heating pan is evenly distributed from above. The object to be kept warm can be properly kept warm in an optimal humidified state while preventing excessive moisture absorption and water absorption in local areas such as the placing part of the object to be kept warm in the heat insulation pan.

Therefore, it is possible to provide a heat-retaining basket that can properly keep breads, which must be kept uniformly at an appropriate level of humidity, warm.
