Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an operating button for an oil hot air heater that burns fuel and uses the combustion heat for heating.

Conventional technology In recent years, as people have become more aware of the ease of use and safety of household heaters that utilize combustion heat, an increasing number of home heaters have been used to burn fuel, mix it with indoor air using a blower, and use it as warm air for heating. and its own improvements have been made.

An example of a conventional oil hot air heater will be described below with reference to the drawings.

In FIGS. 2 and 3, 1 is the main body case of the oil hot air heater, which has an operating section (described later) for setting operating conditions on the upper part and a hot air outlet 2 in the middle lower part. . The operation section is composed of an operation base 3 on which operation details are displayed on its surface, an operation base reinforcement 4 on its back surface for increasing its strength, and various operation buttons. The above operation buttons include timer button 5 for setting the timer operation of the oil hot air heater.
, two setting buttons 6 and 7 that normally increase or decrease the set temperature and the timer set time when the timer is running, a 3-hour extension button 8 that returns the function that stops combustion every 3 hours, and a 3-hour extension button 8 that turns on and off the operation. There is an operation button 9 to turn off the power. The three-hour extension button 8 and the operation button 9 are arranged adjacent to each other and separated from other buttons. Further, a lock type switch 9a is used as the operation button 9, and a non-lock type thin switch (not shown) is used as the other operation buttons.

In the above configuration, turning on and off the operation button 9 turns on and off the combustion of this oil hot air heater, and operation of other operation buttons sends a signal to the control section, and under the set operating conditions. This oil hot air heater uses combustion. Furthermore, for safety reasons, this oil hot air heater automatically stops operating every 3 hours, and can be extended by pressing button 8 to extend the operation for 3 hours. . In addition, the operation button 9 protrudes (solid line) as shown in FIG. In other words, it is approximately the same as position D of the 3-hour extension button 8, or is slightly more protruding than that.

Problems to be Solved by the Invention However, the conventional configuration described above has the following problems. That is, the operation button 9 and the 3-hour extension button 8 control ON/OFF of combustion of the oil hot air heater, and have functionally different characteristics from other operation buttons. The operation button 9 is a lock type operation switch 9a, and the operation button 9 is a lock type operation switch 9a.
The time extension button 8 is a non-locking type, and the run button 9 is always protruded and easier to press. Therefore, there is not much of a problem when turning on and off the operation of the oil hot air heater, but if the operation is extended for 3 hours, it is easy to press the operation button 9 by mistake, and the operation will be turned off and the extinguisher will be turned off at that time. This causes problems such as odor and indoor air pollution.

This invention solves the above conventional problems,
To provide an oil hot air heater that prevents erroneous operations such as stoppage and extension of operation from occurring.

Means for Solving the Problems In order to solve the above problems, the operation button of the oil hot air heater of the present invention is protruded from the extension button when the operation is turned off, and is recessed from the extension button when the operation is turned on.

Effects The present invention has the above-mentioned configuration, and when starting or continuing operation, it is only necessary to press the button on the side that is more protruding, and with a simple configuration, it is possible to reduce erroneous operations by the user and improve the usability. I can do it.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Parts that are the same as those of the conventional example will be denoted by the same reference numerals, detailed explanations will be omitted, and the explanation will focus on the different parts.

In FIGS. 1 and 2, the operation button 10 is
In the off state (operation stopped), it protrudes as shown by the solid line in Fig. 1, but in the on state (operation), as shown by the two-dot chain line A, the position of the 3-hour extension button 8 on the top surface is higher than the broken line B. , and is recessed deeper than the surface 3a of the operation base 3.

Therefore, it is necessary to turn on the combustion of the oil hot air heater.
The operation button 10 and the 3-hour extension button 8, which have functionally different characteristics from other operation buttons that control OFF, are used to turn on and extend combustion, i.e.
The button for the function to be turned on is always prominent and easy to press. Additionally, the button that turns combustion off is set further back than other parts. In other words, the protruding button is used to turn combustion on, and the recessed button is used to turn combustion off. It is possible to reduce the amount of fire extinguishing caused by unnecessary fire extinguishing, and prevent extinguishing odors and indoor air pollution caused by unnecessary extinguishing. Note that 10a in the figure indicates an operation switch.

Effects of the invention As described above, according to the invention, the protrusion and recess of the operation button and extension button are matched to the ON/OFF function, so it is possible to reduce erroneous operations and improve the usability with a simple configuration. , the effect is great.
