Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a water heater that has a heating device in the upper part of the main body and heats a liquid container such as coffee that is placed on a mounting table on the top of the main body. In particular, it relates to the mounting structure for power switches and the like. (B) Prior art When heating a liquid container by placing it on a mounting table as in a general water heater of this type, even if the container is handled carefully, the liquid inside may sometimes spill. This has been transmitted from the outer surface of the main body to the switch mounting plate and corroded the switch, causing a reduction in the electrical insulation of the switch. Many switch mounting structures have been devised to deal with this problem, but the structures are complicated and
In many cases, the operability of the switch deteriorated, and even the installation workability deteriorated. (c) Purpose of the invention The present invention is a switch mounting structure that prevents the electrical insulation properties of the switch from deteriorating due to liquids, simplifies the mounting structure and work, and allows the switch to be operated smoothly. The purpose is to ensure the insulation performance of the switch. (d) Structure of the device The present invention is a water heater that has a heating device in the upper part of the main body and heats a liquid container such as coffee placed on a mounting table on the top surface of the main body. A support plate disposed at a position retracted rearward from the flange, a mounting plate for fixing a main body such as a power switch to the support plate, which is inserted through the support plate and protrudes inside the main body, and the support plate a front plate that faces the front end flange with a gap therebetween and is disposed flush with the front end flange and has an opening through which the operating section of the switch protrudes forward; This is a water heater switch mounting structure in which a horizontal flange is formed that closes the upper surface of the gap, and the end of the flange is bent upward at a position rearward from the support plate to form a guide flange. (E) Embodiment Figure 1 is a front view of a coffee boiler which is an embodiment of the water heater of the present invention, and Figure 2 is a side view of the coffee boiler, also partially cut away and with a liquid container placed thereon. A spray head 3 attached to the end of a hot water extraction pipe 2 of a water heater (not shown) installed inside the main body 1 is installed in the front space of the main body 1 formed in a letter shape.
A damper 4 is hung so that it can be pulled out freely and receives the hot water sprayed from the tank. Further, a mounting table 7 on which a decanter 6 is placed as a liquid container for receiving the coffee beverage dripping from the lower extraction port 4A of the damper 4 is installed on the upper surface plate 5 at the lower part of the main body 1, and the mounting table 7 is disposed opposite to the lower part of the mounting table 7. A heater 8 is disposed inside the main body 1. Various switches 9 , 10 such as a power switch are mounted on the front of the main body 1 according to the mounting structure of the present invention.
The details of the installation structure of the power switch 9 are shown in FIGS. 3 and 4 as representative examples below.
This will be explained based on the drawings and FIG. Reference numeral 5 denotes the lower upper surface plate of the main body which can be attached and detached using the four screws 12 shown in FIG. A flange 5B is formed. The top plate 5 has rearward horizontal flanges 13A and 13B at a position recessed rearward from the front end flange 5A, upper and lower horizontal flanges 13A and 13B, forward-facing L-shaped flanges 13C on the left and right, and an insertion hole 13D in the center. Support plate 1
3 is arranged, the switch body 9A is made to protrude rearward by passing through the insertion opening 13D of the support plate 13 , and the switch mounting plate 14 fixed to the front surface of the switch body 9A is attached to the support plate by upper and lower screws 15. 13
to be screwed together. Further, a front plate 16 is disposed facing the support plate 13 with a distance L therebetween and flush with the front end flange 5A of the upper plate 5 . The front plate 16 forms an opening 16C through which the operation part 9B of the switch 9 that operates as a seesaw protrudes forward, and the upper part is bent rearward to form an opening 16C with a gap L.
It has a horizontal flange 16A that closes the support plate 13 , and a guide flange 16B whose end is bent upward at a position rearward from the support plate 13. Then, the horizontal flange 13A of the support plate 13 and the horizontal flange 16A of the front plate 16 .
are fixed with screws 17, and the front end flange 18A of the lower side plate 18 of the main body is sandwiched between the L-shaped flange 13C of the support plate 13 and the side of the front plate 16 , and the three are fastened together with the screws 19. do. The lower upper surface plate 5 of the main body is attached last after the attachment of the support plate 13 , switch 9, and front plate 16 is completed, and the attachment of the power switch 9 is completed. Furthermore, the other switches 10 and 11 are also installed in the same way as the power switch 9 . With the switch mounting structure as described above, the front plate 16 , which is spaced apart from the support plate 13 to which the switch body 9A is attached, prevents coffee beverages from attacking the switch body 9A from the front, and prevents the horizontal flange 16A and guide flange of the front plate 16 from attacking the switch body 9A from the front. 16B reliably prevents coffee drinks that have entered through the gap between the top plate 5 and the front plate 16 from damaging the switch body 9A. Further, since the switch operating portion 9B is located at a front position protruding from the front plate 16 , the switch operation can be easily performed. (f) Effects of the invention This invention reliably prevents contact between the switch and liquid through the positional relationship between the support plate to which the switch body is attached and the front plate, and the action of the horizontal flange and guide flange that bend the front plate. This provides advantages in that the insulation performance of the switch can be ensured, the switch is easy to operate, and the mounting structure and assembly work are simple. Furthermore, the present invention can be widely implemented in various types of water heaters not equipped with a coffee brewing mechanism without departing from the spirit of the present invention.
