Abstract

PURPOSE:To minimize the heat transfer to the outside from the heating plate side by fixing the heating plate having a heater to a shielding tube on its outer periphery by claw coupling in partial contact. CONSTITUTION:In a warmer provided with a heating plate 5 holding the warming heater 4 of a hot-water feeder and a shielding tube 3 covering the outer periphery of the heating plate 5 to prevent the heat radiation to the outside, a claw section 6 having an inclined face 8 is formed on the upper end section of the shielding tube 3, and the heating plate 5 is fixed by the claw section 6. The heat of the heater 4 is prevented from heating an outer wall 2 by the shielding tube 3 around the heating plate 5, the heating plate 5 is fixed by the claw section 6, thus the contact area between the heating plate 5 and the shielding tube 3 is reduced, heat is hardly transferred, and the temperature of the shielding tube 3 can be suppressed low.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heater mounting device for fixing a heat-retaining heater of a hot water water heater that produces and retains hot water for dissolving powdered milk.

Conventional technology> Conventionally, this type of heat-retaining heater has been fixed by wrapping it in a band around the outer circumference of a ring-shaped heating plate, and then supporting the heating plate with an arm or the like so that it floats in the air and fixing it to the base. taking it. In addition, since the heater reaches high temperatures, the material surrounding the heater must be made of a material that can withstand high temperatures, and the external dimensions must be increased in order to keep a sufficient distance from the heater so that the surrounding area does not become hot, or the outer dimensions must be increased to support the heater. The arms are also thin to make it difficult to conduct heat, and the strength is weakened by making them d long.

Problems to be Solved by the Invention In other words, conventional heater mounting devices have had drawbacks such as the distance around the heater becoming large and the strength of the heater mounting portion becoming weak.

In view of the above-mentioned circumstances, it is an object of the present invention to provide a heater mounting device that solves the above-mentioned problems by using a nail engagement structure to fix the heat plate supporting the heater and the heat shield cylinder.

Means for Solving the Problems> The present invention provides a heat insulator that includes a hot plate that holds a heater and a heat shield tube that covers the outer periphery of the hot plate and prevents heat radiation to the outside. A claw portion with an inclined surface is formed, and the hot plate is fixed with the claw portion.

Due to the structure described above, the heat shield cylinder around the hot plate prevents the heat of the heater from heating the outer wall, and the claws provided at the top end fix the hot plate, so the heat shield tube prevents the heat from heating the outer wall. The contact area between the plate and the heat shield tube also becomes smaller, making it difficult for heat to transfer. Therefore, the temperature of the heat shield can be kept low, and by attaching this heat shield to the base, there is no need to use expensive heat-resistant materials for the base, and the distance from the heat shield to the outer wall can be reduced. Therefore, the overall external size can be reduced.

Embodiments> Hereinafter, embodiments of the present invention will be described based on the drawings.

The drawing shows a hot water water heater equipped with a heater for heating a supplementary milk bottle and a heater for producing hot water for dissolving powdered milk. 1- is an exterior case with a predetermined shape, inside which a cylindrical base part 2 is formed; A metal heat shielding cylinder 3 is installed inside the base part 2.

A ring-shaped hot plate 5 with a heater 4 provided on the outer wall of the cylinder is attached to the inside of the heat shield cylinder 3. In this case, a claw portion 6 with a slope 8 is formed at the upper end of the heat shield cylinder 3, and a flange portion 5 of the heat plate 5 is formed.
A notch 9 into which the claw 6 of the heat shielding cylinder 3 is inserted is provided, and the claw 6 is fitted into the cutout 9 to position the hot plate 5, and at the same time, the claw 6 is bent inward and its inclined surface 8 is inserted. hot plate 5
Pinch and secure (see Figure 3).

Next, to explain this operation, first, the milk supplement bottle 7 is placed in the cylindrical hot plate 5 on which the heater 4 is arranged, and the heater 4 is energized, and the heat passes through the hot plate 5 and keeps the milk supplement bottle 7 warm. At this time, heat is radiated to the outer periphery at the same time, heating the outer periphery, but since the heat shield tube 3 is made of metal and insulates the heat, there is no direct heat effect on the base part 2 located on the outer periphery, and the outer periphery is heated. The temperature of the base part 2 does not become too high, so that it is possible to use a conventional resin material.

Furthermore, since the heat shield cylinder 3 and the heat plate 5 are engaged with each other by claws, the contact portion is only a small portion, and there is little heat transfer from the heat plate 5 to the heat shield cylinder 3, making it difficult for the heat shield cylinder 3 to become high temperature. Therefore, the heat shield cylinder can be securely fixed to the base portion 2, and the heater 4 can be securely fixed.

<Effects of the Invention> As described above, the heater mounting device of the present invention has a structure in which the heat plate with the heater is fixed to the heat shield cylinder on the outer periphery by claw engagement that makes partial contact with the heat plate side. The heat transfer to the outside can be further minimized, the base part disposed around the outer periphery of the heat shield cylinder can be made of ordinary resin material and can be made inexpensive, it is easy to assemble, the entire device is compact, and This has the advantage that the heater (hot plate) can be fixed without using separate parts such as screws.
