  Here, when the operation unit is a push button switch, the push button switch protrudes forward from the operation panel. When the operation panel is flush with the front surface of the heating device, the push button switch projects forward from the front surface of the heating device. For this reason, there is a risk of being caught by the push button switch and erroneously operated.

  Therefore, the present invention has been made in view of the above-described background, and has as its object to provide a heating device that does not easily cause an erroneous operation of a push button switch.

  In order to solve the above-mentioned problem, a heating device according to the present invention includes a front wall, a concave surface disposed below the front wall, and a concave surface recessed rearward from a front surface of the front wall, and a display unit disposed in the concave surface. And a push button switch disposed in the concave surface, wherein the concave surface is an inclined surface that is gradually inclined backward from a lower part toward an upper part, and the display unit and the push button switch are the inclined surface. It is characterized by being arranged on the top and inclined.

According to the invention, the amount of protrusion of the push button switch from the front surface of the front wall is reduced by the amount of depression of the concave surface. For this reason, it is difficult for the push button switch to be caught, and the possibility of erroneous operation is reduced.
In addition, the display unit disposed in the inclined plane faces obliquely upward, not forward (in the horizontal direction). For this reason, even if it is arrange | positioned at the lower part of a front surface, a display part becomes easy to see.
Similarly, since the push button switch is directed obliquely upward, the pressing direction of the push button switch is obliquely downward. Therefore, the operator can easily press the push button switch from above, and the operability is improved.

  In the above invention, the pressed surface of the push button switch is gradually inclined rearward from a lower portion to an upper portion, and an angle formed by the pressed surface and the front surface is defined by the inclined surface and the front surface. It is preferably larger than the angle.

  According to the above configuration, since the pressed surface faces upward from the inclined surface, the operator can easily press the push button switch from above, and the operability is further improved.

  Further, in the invention, it is preferable that identification information for identifying the push button switch is indicated on a pressed surface of the push button switch.

  According to the configuration, since the identification information is indicated on the pressed surface that is inclined more than the concave surface (inclined surface), the operator can recognize the identification information more than when the identification information is indicated on the inclined surface. Easy and erroneous operation can be avoided.

  Advantageous Effects of Invention According to the present invention, it is possible to provide a heating device that does not easily cause erroneous operation of a push button switch.

It is the perspective view which showed the heating apparatus which concerns on embodiment of this invention. It is the perspective view which expanded the operation panel and its vicinity. It is sectional drawing which cut the operation panel in the up-down direction and the front-back direction.

In other words, the display unit 20 and the basic operation unit 30 arranged on the panel surface 7A are inclined and face obliquely upward on the front side. The angle θ1 formed by the panel surface 7A and the perpendicular L1 is preferably in the range of about 2 ° to 8 °, and is 3 ° in the present embodiment. According to this, the viewing angle of the display unit 20 shifts upward, and the operator can recognize the display content of the display unit 20 without lowering the eye height. As a result, the operator does not need to bend down and lower his / her line of sight, thereby reducing labor.
Note that if the angle θ1 is increased to about 10 °, it is difficult for the operator to recognize the display content when viewing the display unit 20 from a distant low position. Therefore, the angle θ1 should be limited to about 8 ° at the maximum. Is preferred.
Similarly, since the basic operation units 30 face obliquely upward, the moving direction of the basic operation units 30 is obliquely downward. Therefore, the operator can easily press the basic operation unit 30 from above, and the operability is improved.

The operation surface (pressed surface) 36a of the basic operation unit 30 is gradually inclined rearward from the lower part to the upper part.
The angle θ2 formed by the operation surface 36a and the perpendicular L1 is larger than the angle θ1 formed by the panel surface 7A and the perpendicular L1, and the angle θ2 is preferably about 10 ° to 20 °, and is 16 ° in the present embodiment. .
As a result, the operation surface 36a faces further upward than the panel surface 7A, so that the operator can easily press the basic operation unit 30 from above without changing the ease of recognition of the display unit 20. Is more improved.
Further, since the identification information on the operation surface 36a faces further upward than when it is printed on the panel surface 7A, the operator can easily recognize the identification information, and an erroneous operation can be avoided.

The embodiment has been described above, but the present invention is not limited to the example described in the embodiment.
For example, in the embodiment, only the basic operation unit 30 is formed on the panel surface 7A, but the applied operation unit 50 may be further formed on the panel surface 7A.
Although the identification information is shown on the operation surface 36a, it may be shown on the panel surface 7A.
