Description

The present disclosure relates to a room heating device and a toilet device.

BACKGROUND ART Toilet devices equipped with a room heating device have been known. For example, in Patent Document 1 below, a first cover member and a second cover member are assembled. A warm air fan is provided between the first cover member and the second cover member. A filter is arranged to cover an air intake port formed on a side surface of the first cover member. Air is introduced into the hot air fan from the air intake through the filter. Warm air heated by the hot air fan is blown out from the outlet. As a result, the inside of the toilet is heated.

Next, the mounting structure of the filter 4 will be explained.
As shown in FIG. 6, a filter insertion portion s1 is formed between the case base surface 213 of the first case member 21 and the filter cover 5. As shown in FIG. The filter 4 can be inserted into the filter insertion portion s1 in the −Y direction.

The filter base plate portion 411 of the filter 4 is disposed in contact with the case base surface 213 of the first case member 21 . The filter inclined plate portion 412 of the filter 4 is disposed in contact with the case inclined surface 214 of the first case member 21 .

The first cover plate portion 511 of the filter cover 5 is disposed in contact with the filter base plate portion 411 of the filter 4 . The second cover plate portion 512 of the filter cover 5 is arranged apart from the filter inclined plate portion 412 of the filter 4 on the −X side.

The first cover plate portion 511 of the filter cover 5 is provided with a first pressing portion 516 that protrudes toward the +X side. The first pressing portion 516 is inclined so as to gradually move toward the −X side (separate from the filter 4) as it goes toward the −Y side.

The second cover plate portion 512 of the filter cover 5 is provided with a second pressing portion (pressing portion) 517 that protrudes toward the +X side. The second pressing portion 517 contacts the −Y side end of the protrusion 414 of the filter 4 and presses the protrusion 414 toward the first bottom wall portion 211 side (+X side) of the first case member 21. There is.

The end 41d of the filter 4 is positioned by the -Y side end 214d of the case inclined surface 214 of the first case member 21 and the -Y side end 5d of the filter cover 5. The filter 4 is positioned by the -Y side end 5d of the filter cover 5 and the second pressing part 517.

In the filter insertion part s1, the clearance (gap) formed between the end 214d of the case inclined surface 214 of the housing 2 and the end 5d of the filter cover 5 is defined as the clearance (gap) at the location corresponding to the tip of the holding part. clearance) c1. In the filter insertion part s1, the clearance formed between the inclination switching part 218 of the housing 2 and the second cover plate part 512 of the filter cover 5 is defined as a clearance (a clearance at a location corresponding to the middle part of the holding part) c2. do. The clearance c1 is smaller than the clearance c2.

As shown in FIG. 3, the end 41c of the filter 4 is arranged flush with the +Y side end 2d of the housing 2.

In the room heating device 10 described above, when attaching the filter 4, the filter cover 5 is first attached to the first case member 21 with screws or the like. Holding the grip part 415 of the filter 4, insert the filter 4 through the gap between the insertion part 216 of the first case member 21 and the first bottom wall part 211. Insert the filter 4 into the filter insertion part s1 of the housing 2 in the -Y direction (insertion direction). The filter 4 is guided by the case slope 214 of the housing 2, and the filter 4 is inclined along the slope direction of the case slope 214. The filter 4 is gradually inclined toward the −X side as it goes toward the end portion 41d. When the protruding portion 414 of the filter 4 comes into contact with the first pressing portion 516 of the filter cover 5, it is elastically deformed so as to bend toward the +X side. When the tip of the projection 414 reaches the second pressing portion 517, the projection 414 is pressed by the second pressing portion 517, producing a click feeling.

According to the toilet device 100 configured in this way, an air intake port 215 is formed in the case inclined surface 214 of the housing 2 . The filter inclined plate portion 412 of the filter 4 is disposed in contact with the case inclined surface 214. Therefore, the gap between the air intake port 215 and the filter 4 is suppressed, and dust can be suppressed from being sucked into the hot air fan 6.

A clearance c1 formed between the end 214d of the case slope 214 of the housing 2 and the end 5d of the filter cover 5 is the clearance c1 between the slope switching part 218 of the housing 2 and the second cover plate part 512 of the filter cover 5. It is smaller than the clearance c2 formed between them. Therefore, separation of the end portion 41d side of the filter 4 from the case inclined surface 214 of the housing 2 is further suppressed.

The second pressing portion 517 of the filter cover 5 comes into contact with the -Y side end of the protrusion 414 of the filter 4, and pushes the protrusion 414 toward the first bottom wall 211 side (+X side) of the first case member 21. is being pressed. Therefore, separation of the vicinity of the protrusion 414 of the filter 4 from the surface 211b of the housing 2 is further suppressed.

An end 41d of the filter inclined plate portion 412 of the filter 4 is positioned by an end 214d of the case inclined surface 214 of the housing 2 and an end 5d of the filter cover 5. Therefore, even if the end 41d side of the filter 4 warps toward the filter cover 5 side (-X side), the filter 4 is held down by the filter cover 5, and separation of the filter 4 from the case slope 214 is suppressed. .

The end 41c of the filter 4 is arranged flush with the end 2d of the housing 2. Therefore, during cleaning or maintenance, when the functional part 12 is raised and the filter 4 is replaced, the filter 4 and the functional part 12 do not interfere when the functional part 12 is lowered and returned to its original position. .

The various shapes and combinations of the constituent members shown in the embodiments described above are merely examples, and can be variously changed based on design requirements and the like without departing from the spirit of the present disclosure.

For example, in the embodiment described above, the filter cover 5 is provided. The present invention is not limited to this, and as long as the filter 4 is disposed along the case inclined surface 214 of the housing 2, the filter cover 5 may not be provided.

In the above embodiment, the case inclined surface 214 is formed on the first case member 21. However, the present invention is not limited to this, and the filter 4 may be formed with an inclined surface that is inclined so as to gradually move away from the inside of the housing 2 toward the distal end side in the insertion direction.

In the above embodiment, the clearance c1 formed between the end 214d of the case slope 214 of the housing 2 and the end 5d of the filter cover 5 is the same as the clearance c1 formed between the end 214d of the case slope 214 of the housing 2 and the end 5d of the filter cover 5. It is smaller than the clearance c2 formed between the cover plate part 512 and the cover plate part 512. The invention is not limited to this, and the clearance c1 may be larger than the clearance c2, or the clearance c1 and the clearance c2 may be substantially the same.

In the embodiments described above, the inclined surface is provided on the housing 2. The present invention is not limited to this, and the filter cover 5 may be provided with an inclined surface. The surface of the filter cover 5 facing the filter 4 side (+X side surface) may be inclined so as to gradually move toward the +X side as it moves toward the -Y side. When inserting the filter 4, the filter 4 is guided by the +X side surface of the filter cover 5.
