Description

[Detailed description of the invention] [Purpose of the invention] (Industrial field of application) The present invention relates to a heating element for a humidifier, and in particular to the outer periphery of a heating pipe connected to a water tank in a humidifier by a joint. The present invention relates to a heating element of a humidifier formed by winding a heating wire around a heating element.

(Prior Art) Conventionally, the heating elements of this type of humidifier include a space type and a bobbin type, and recently the bobbin type, which has good thermal efficiency, has become mainstream.

However, in the case of the heating element of conventional bobbin-type humidifiers, when winding the heating wire around the outer periphery of the heating pipe, one end of the heating wire is held and then wrapped around the heating pipe using a winding machine. Conventionally, in order to hold one end of the heating wire, a wire holding machine for temporarily fixing the heating wire was attached to the heating pipe, and when the work of winding the heating wire was completed, the wire holding machine was removed. It had not been removed.

(Problems to be Solved by the Invention) However, the method for winding the heating wire as described above requires a wire holding machine, has extremely poor working efficiency, and has the disadvantage that it cannot be manufactured at a low cost.

The present invention is an attempt to solve the above-mentioned drawbacks, and aims to provide a humidifier for heating elements that eliminates the need for a wire holding machine for temporary fixing, has good work efficiency, and can be manufactured at low cost. be.

(Structure of the invention) The invention involves wrapping an insulating paper of a predetermined width around a heating pipe attached to the heating element mounting part of a humidifier, and fixing the insulating paper at a predetermined interval around the outer circumference of the insulating paper. Wrap a pair of terminal metal wires, and connect both ends of the heating wire wrapped around the outer periphery of the insulating paper to the pair of terminal metal wires, wrap the heating wire with protective paper, and use a presser wire. It is fixed.

(Function) The heating element of the humidifier of the present invention consists of a pair of insulating papers fixed at a predetermined interval around the outer periphery of the insulating paper wrapped around a heating pipe attached and fixed to the heating element mounting part of the humidifier. When winding the heating wire around the outer periphery of the insulating paper around the terminal metal wire, the work of winding the heating wire can be done efficiently and easily by temporarily fixing one end of the heating wire in advance. Furthermore, by wrapping the heating wire with protective paper and fixing it with a presser wire, heat radiation from the heating wire is prevented and contact of the lead wire with the heating wire is prevented.

(Example) An example of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 is a heating element mounting plate, which forms a heating element mounting portion attached to the humidifier main body 2, and 3 is a water tank installed on the humidifier main body 2.

A pipe supporting lower cut-out piece 4 having a square hole cut out is formed at the upper part of the heating element mounting plate 1, and a substantially U-shaped cut-out is formed at the lower part of the heat generating element mounting plate 1. A lower cut-and-raised piece 5 for supporting the pipe is formed.

A heat generating pipe 6 made of copper is supported by the upper cut-and-raised piece 4 for pipe support and the lower cut-and-raised piece 5 for pipe support, and the lower end of the heat-generating pipe 6 is attached to the lower part of the heating element mounting plate 1. It is fixed by a pipe fitting 8 which is tightened by a set screw 7.

The upper end of the heat generating pipe 6 is connected to a steam pipe 10 via a connecting pipe 9, and the lower end of the heat generating pipe 6 is connected to a water tank 2 via a substantially V-shaped elbow pipe 11.

Further, the outer periphery of the heat generating pipe 6 is wrapped with an insulating paper 12 having a predetermined width. The insulating paper 12
Terminal metal wires 13, 13, which are wire rods such as annealed copper wire and copper wire, are wound around the upper and lower ends of the wire, respectively, and both ends of each terminal metal wire 13 are twisted together to form a twisted portion 13a. An insulating paper 12 is fixed to the heat generating pipe 6 by. These terminal metal wires 13,1
The twisted portions 13a, 13a of No. 3 are provided at the same position. A heating wire 14 is wound between the terminal metal wires 13, 13 on the insulating paper 12.

To wind the heating wire 14, first, one end of the heating wire 14 is wound and held around the twisted portion 13a of the terminal metal wire 13 located above the insulating paper 12. After temporarily fixing the heating wire 14 in this way, use a winding machine etc. to tie the heating wire 14 to the insulating paper 12.
Wrap it evenly between the terminal metal wires 13 and 13 on the top, and wrap the other end of the heating wire 14 around the twisted part 13a of the terminal metal wire 13 located below the insulating paper 12. The winding of the heating wire 14 around the heating pipe 6 is then completed.

Further, a protective paper 15 is wrapped around the outer periphery of the heat generating wire 14 wound around the heat generating pipe 6 so as to have a wrap width approximately equal to the distance between the terminal metal wires 13, 13. The wrapped protective paper 15 is fixed to the heating wire 14 by wrapping a presser wire 16 around the center thereof. The protective paper 15 serves to prevent heat dissipation from the heat generating wire 14, to prevent a lead wire described later from coming into contact with the heat generating wire 14, and to prevent pitch deviation of the heat generating wire 14 due to external force. In addition, the holding wire 16 is inserted between the pitches of the heating wire 14 to more firmly fix the protective paper 15 to the heating wire 14,
This prevents the protective paper 15 from shifting. In the figure, 17,
17 is a crimp terminal 18, which is attached to the twisted portions 13a, 13a of the terminal metal wires 13, 13, respectively.
The lead wires are connected by 18.

The heating element of the humidifier with such a configuration includes the lead wires 17,
By energizing 17, the lead wires 17, 17
The heating wire 14 whose both ends are connected via a pair of terminal metal wires 13 and 13 generates heat, and the water in the heating pipe 6 connected to the water tank 3 is heated by the heating wire 14. The steam is heated and boiled, and the steam is supplied to the outside from the steam port of the steam pipe 10 connected to the heat generating pipe 6.

[Effect of idea]

According to the present invention, the heating element of the humidifier consists of a pair of insulating papers fixed at a predetermined interval around the outer periphery of the insulating paper wrapped around the heating pipe which is attached and fixed to the heating element mounting plate of the humidifier. Since the metal wire for the terminal is provided, the insulating paper can be temporarily secured at one end of the heating wire, which is necessary when wrapping the heating wire around the outer periphery of the insulating paper, without using a wire holder to attach it to the heating pipe prepared in advance. This can be easily done by using a metal wire for the terminal to be fixed as the terminal, improving work efficiency and manufacturing at low cost.

In addition, the heating wire is wrapped in protective paper and fixed with a presser wire, so the protective paper prevents heat radiation from the heating wire, prevents the lead wire from contacting the heating wire, and prevents the heating wire from shifting due to external force. can.
