Description

[Detailed Description of the Invention] [Technical Field] The present invention concerns the positional relationship between the air inlet to a hot air heater unit built into a cabinet such as a toilet wall cabinet and the outlet from the hot air heater unit. be.

[Background Art] It has been known to have a hot air heater unit installed in a cabinet such as a toilet wall storage. As shown in FIG. 7, this cabinet with a warm air heater unit was provided with a blowout port 4 at the bottom of the cabinet 1 so as to blow hot air from under the feet. In the case of the one shown in Fig. 7, the intake port 3 is located considerably above the blowout port 4, and hot air warmed by the hot air heater unit 2 is sent to the bottom blowout port 4 through a duct 15 and blown into the room. Since the duct 15 is long, there is heat loss, resulting in poor thermal efficiency. For this reason, it is conceivable to place the outlet 4 and the intake port 3 close to each other in the lower part of the cabinet 1 as shown in FIG. 8, but in the case of the conventional example shown in FIG.
Since the air intake port 3 and the air intake port 3 are close to each other, there is a problem in that a portion of the hot air blown from the air outlet 4 is short-circuited and flows to the air intake port 3 as shown by the arrow in FIG.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to eliminate the need for long ducts, eliminate heat loss, and ensure that the warm air blown from the outlet is inhaled. To provide a structure of a cabinet with a hot air heater unit that is free from the risk of short circuit to the mouth.

[Disclosure of the invention] The structure of the cabinet with a hot air heater unit of the present invention is such that a hot air heater unit 2 is disposed at the bottom of a cabinet 1, and an intake port 3 for the hot air heater unit 2 is provided on the outer surface of the cabinet 1. The air outlet 4 from the warm air heater unit 2 is placed close to the air outlet 4, the air outlet 4 is positioned above the air intake port 3, and the air outlet 4 is projected further into the room than the air intake port 3. By employing such a configuration, the above-mentioned object of the present invention has been achieved. That is, in the present invention, by bringing the intake port 3 and the outlet 4 closer together, there is no need to use a long duct, and the outlet 4 protrudes further toward the indoor side than the intake port 3. The hot air blown out from the outlet 4 is no longer short-circuited to the intake port 3.

The present invention will be explained in detail below with reference to Examples. In the embodiment shown in the drawings, the cabinet 1 is an embodiment of a toilet wall storage body. This toilet wall storage unit has a part of the front and back part or the front part embedded in the wall and becomes a part of the wall. You can. The cabinet 1 is provided with a storage section 13, and a door 14 is provided at the front opening of the storage section 13. A hot air heater unit 2 is installed in the lower part of the cabinet 1. Further, a grill 12 is provided on the outer surface of the cabinet 1.
An inlet 3 into the hot air heater unit 2 and an outlet 4 from the hot air heater unit 2 are arranged close to each other. Here, the outlet port 4 is higher than the intake port 3.
is located above, and the outlet 4 is made to protrude further into the room than the intake port 3. Here, the cabinet 1 is formed of polyester decorative plywood, and a warm air heater unit 2 is connected to the underside of the bottom plate 5 of the cabinet 1 via a cushioning material 6 made of chloroprene rubber foam or other foam.
The warm air heater unit 2 is mounted on the lower support member 7. The hot air heater unit 2 is provided with a heater 8 and a fan 9. In the embodiments shown in FIGS. 3 and 4, the buffer material 6 covers the outer periphery of the hot air heater unit 2 except for the air inlet 10 and outlet 11. Further, in the case of a chloroprene rubber foam as the cushioning material 6, a foam having a foaming ratio of, for example, twice is used, and the thickness is about 10 mm. In order to save the amount of the cushioning material 6 used, the hot air heater unit 2 may be partially supported by the cushioning material 6 without covering substantially the entire surface of the hot air heater unit 2. The air sucked in from the intake port 3 enters from the entrance 10, is heated by the heater 8, becomes warm air, and is blown into the room from the outlet 4 via the outlet 11. In this case, since the outlet 4 protrudes further toward the indoor side than the intake port 3, the hot air blown out from the outlet 4 will not be short-circuited to the intake port 3 side. By the way, as shown in FIG. 3, the entrance 10 of the hot air heater unit 2 is opened downward, and this entrance 1
By locating the fan 9 above the fan 9, even if insects or dirt enters the fan 9, they will fall below the fan 9, and the insects or dirt will not accumulate near the fan 9 and adversely affect the motor. FIG. 6 shows another example of the present invention, in which the intake port 3 is inclined so that it is lower toward the indoor side, and the outlet port 4 is inclined so that it is higher toward the indoor side. This prevents the hot air from the outlet 4 from short-circuiting to the intake port 3. Also spout 4
Protruding toward the indoor side means that the distance L from the heater 8 to the grill 12 can be increased as shown in FIG. 5, and as a result, the temperature of the grill 12 can be prevented from rising. Furthermore, since the intake port 3 portion at the bottom of the grille 12 is set back, this portion serves as a recess for the cabinet 1.

[Effects of the invention] As described above, the invention disposes the hot air heater unit at the bottom of the cabinet, and brings the intake port to the hot air heater unit and the outlet from the hot air heater unit close to the outer surface of the cabinet. Place the
The outlet is located above the intake port,
Since the outlet protrudes further into the room than the intake port, there is no need to use a long duct and heat loss can be prevented. The hot air blown out from the outlet no longer short-circuits to the intake port.
