[Industrial applications]

 The present invention relates to improvement of a liquid warmer using a microwave oven.

[0002]

[Technical background of the device]

 When heating liquids such as water, sake, soups and miso soup using a microwave oven in a general household, put the liquids in an open container and set them in the microwave oven. However, it is usually taken out after being subjected to high-frequency induction heating for a prescribed time and then taken out and used. In this way, containing the number of liquids to be heated or heated in an open container is not efficient because the latent heat of vaporization of liquids due to high-frequency dielectric heating is large and requires a lot of time. There are challenges. This means that power is wasted a lot, and the total amount of power wasted during the year is vague, which is extremely uneconomical.

An object of the present invention is to provide a liquid warmer in which the amount of latent heat of vaporization of liquid due to high frequency dielectric heating is extremely small and power consumption is not wasted.

[0004]

[Means for Solving the Problems]

 The structure of the present invention which solves the problems of the prior art is such that a lid made of the same material as this is detachably attached to a cylindrical container body made of a heat-resistant synthetic resin material with an airtight structure, and the lid is attached to the lid body. A pressure adjusting means having a float valve structure for deviating the heated air in the container body and an openable / closable liquid pouring means are provided, and the liquid pouring means is constituted by a pouring outlet provided with a three-way switching valve, The pressure adjusting means, which communicates with and shuts off the container body via a three-way switching valve, is provided in the upper part of the liquid pouring means, and the pressure adjusting means and the liquid pouring means that can be opened and closed are separately provided. In this configuration, both means are provided at symmetrical positions where the lid body is separated from each other.

[0005]

[Operation] The amount of air in the container body in which the liquid is sealed is small, and the heating air is automatically discharged by the high-frequency dielectric heating due to the rise of the internal pressure through the three-way switching valve to the outside by the action of the pressure adjusting means. The latent heat of vaporization is minimized, the heating efficiency is good and there is no waste of power. For liquids such as water and sake, it is possible to inject water arbitrarily from the spout without opening the lid, and the warmer itself can be used as a heat retaining container. The pressure adjusting means and the liquid pouring means are provided at mutually separated symmetrical positions of the lid, and a handle member is attached to the side of the container body on the side of the pressure adjusting means so that the contents of the pressure adjusting means can be controlled when pouring the liquid. It can reasonably prevent the liquid from leaking to the outside.

【Example】

 Next, details of the embodiments of the present invention will be described with reference to the drawings. 1 is a front view of a warmer of the present invention, FIG. 2 is a vertical side view of the warmer, FIG. 3 is a vertical cross-sectional view of a liquid pouring means showing a pourable state of liquid, and FIG. 4 is a pressure adjusting means. FIG. 5 is a vertical cross-sectional view showing the closing of the liquid pouring means, and FIG. 5 is a partially cutaway side view of another embodiment.

Referring to FIGS. 1 to 4, the first embodiment of the present invention will be described in detail. Reference numeral 1 denotes a cylindrical container body made of a heat-resistant synthetic resin material such as polypropylene (PP) or polycarbonate. A lid 2 made of the same material as that of the container body 1 is hermetically attached to the opening of the container body 1 in a hermetically and detachably attachable manner. A three-way switching valve 3 provided with a T-shaped flow passage 3a is rotatably supported on one side of the upper portion of the lid 2, and a T-shaped flow passage 3a of the three-way switching valve 3 and a vertical flow passage 4 are provided. A liquid spouting body 6 provided with a spout 5 communicating with the inside of the container body 1 is attached airtightly. Furthermore, a small-diameter pressure adjusting action having the same axis as that of the vertical flow path 4 and a passage 7 for escaping heated air are formed in the upper portion of the liquid pouring body 6, and the upper opening edge of this passage hole 7 is formed. A low pressure regulating valve 10 having a float valve structure having a conical valve body 8 capable of opening and closing and having a weight 9 for pressure regulation attached to the upper end is mounted so as to be vertically movable. In the figure, 11 is an opening for discharging heated air to the outside, 12 is a handle member provided on the container body 1 on the side opposite to the liquid pouring body 6 provided on the lid body 2, and 13 is a packing. The weight of the weight 9, that is, the weight of the low pressure adjusting valve 10 and the diameter of the through hole 7 are set so that the pressure in the container body 1 at the time of high frequency dielectric heating is, for example, 0.1 kg / cm ^3. To do.

As is apparent from FIG. 2, the three-way switching valve 3 is rotatably enclosed in the liquid pouring body 6 and is rotated by the shaft portion 3 b protruding from the liquid pouring body 6 to the outside. The knob 14 is attached. By the rotation of the rotary knob 14, as shown in FIG. 1, the T-shaped flow path 3a connects the vertical flow path 4 and the through hole 7, and the high-frequency heating state in which the spout 5 is closed, and FIG. As shown in FIG. 4, the T-shaped flow path 3a connects the vertical flow path 4 and the spout 5 to each other and closes the through hole 7, and as shown in FIG. 4, the T-shaped flow path 3a is perpendicular to the T-shaped flow path 3a. The three postures of the closed posture in which the flow passage 4 is not communicated are obtained. Further, it is desirable to provide a mark (not shown) for switching and holding the three-way switching valve 3 in the three postures on the outer surface of the liquid pouring body 6. It is needless to say that the three-way switching valve 3, the liquid spouting body 6, the low pressure adjusting valve 10, the handle member 12, the rotary knob 14 and the like are made of the same material as the container body 1. Further, if necessary, a vent hole 16 that can be opened and closed by a rotating closing plate 15 is provided on one side of the lid body 2, and the vent hole 16 is opened when pouring out the liquid to inject the liquid. It is desirable to make the output smoothly.

Next, the details of the second embodiment will be described with reference to FIG. 5. A low pressure adjusting valve 10 having a float valve structure is attached to one side of the lid body 2 and the low pressure adjusting valve 10 and the low pressure adjusting valve 10 are separated from each other. The liquid pouring body 6 having the switching valve 17 is provided at the symmetrical position, and the handle member 12 is integrally formed on the side surface of the container body 1 on the side of the low pressure control valve 10. The same components as those of the first embodiment will be designated by the same reference numerals and detailed description thereof will be omitted.

(A) The amount of air in the container main body in which the liquid is sealed is small, and the heating air is automatically released by the action of the pressure adjusting means through the three-way switching valve due to the increase of the internal pressure due to the high frequency dielectric heating, and The latent heat of vaporization of liquid is kept to a minimum, heating efficiency is good, and there is no waste of electricity. (B) In the case of liquids such as water and sake, water can be poured arbitrarily from the spout without opening the lid, and the warmer itself can be used as a heat retaining container. (C) A pressure adjusting means and a liquid pouring means are provided at mutually separated symmetrical positions of the lid, and a handle member is attached to a side portion of the container main body on the pressure adjusting means side to adjust the pressure at the time of pouring the liquid. It is possible to reasonably prevent the content liquid from leaking outside from the means.
