Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a humidifier such as an ultrasonic humidifier for humidifying a room.

(B) Conventional Technology A conventional humidifier of this type is, for example, as disclosed in Japanese Utility Model Laid-Open No. 63-14933, a blower that blows air into a water tank having a humidifier such as an ultrasonic transducer. Was built into the main body of the humidifier, and the mist generated in the water tank was combined with the air from the blower and discharged into the room from the air outlet to humidify the room.

(C) Problems to be Solved by the Invention By the way, in this conventional humidifier, the operation part including the indicator lamp, the humidity setting device for setting the desired humidity, and the operation switch is arranged at the lower front part of the humidifier body. It was difficult to operate because it was installed in. Therefore, if you connect the operation unit case that has operation electrical parts such as operation switch and indicator lamp to the upper part of the main body case that contains the blower and the control board, the operation part will be located on the upper part of the humidifier main body, You will be able to operate in a very comfortable position.

In this case, an insertion hole is formed in the contact portion between the main body case and the operation portion case, and the lead wire connecting the operation board housed in the operation portion case and the control board in the main body case is used as the above insertion hole. There is a need. A connector is attached to this lead wire in order to simplify the connection work. Therefore, the above insertion hole must be of a size that allows the connector to be easily inserted. There will be a gap in. Therefore, the gap between the lead wire and the insertion hole must be closed with a seal member so that the wind of the blower does not leak from the insertion hole, which requires a seal member or the time and effort required to close it with the seal member. there were.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to improve the operability of the device and to save the labor for sealing the lead wire insertion portion.

(D) Means for Solving the Problems The present invention has a water tank portion provided with a humidifying device, a main body case having a blower for feeding air into the water tank portion and a control board, and an upper portion of the main body case. With an operation unit case connected to the operation unit, an operation board housed in the operation unit case and to which operation electric parts such as an operation switch and an indicator lamp are attached, and a connector for connecting the operation board and the control board Lead wires of the main body case and the operation portion case are provided with insertion holes each having a size capable of inserting the connector, and the insertion holes are provided with their centers offset from each other.

In the above configuration, when the operation switch (not shown) is turned on, the first and second pilot lamps (22, 24) are turned on and the humidifier starts operating. Here, when the automatic operation mode is selected by the selection switch (33), the automatic operation display lamp (L) is turned on and the humidifier performs the automatic operation according to the humidity. The second pilot lamp (24)
Light illuminates the water tank (15) and at the same time the inner cover (27)
The light passes through the bottom wall (27A) and is irradiated to the outside from the outer peripheral edge portion of the bottom wall (27A). Then, the blower (7) is driven by the start of operation of the humidifier, and the wind from this blower (7) passes through the ventilation passage (11) while cooling the transformer (8) and passes through the upper space of the atomization water tank (5). The air is sent to the air, where it joins the mist generated from the water (X) generated by the driving of the ultrasonic transducer (6), and then is discharged to the outside from the air outlet (19) to humidify the room. In this automatic operation, for example, when the indoor humidity is 39% or less, it is operated with a humidification amount of about 400 cc / h, and when it is in the range of 40% to 59%, it is operated with a humidification amount of about 200 cc / h, When it exceeds 60%, it is controlled so that the operation is stopped. Further, when the selection button (30B) is pushed to switch the selection switch (33) from the above-mentioned automatic operation mode to the high value of the manual operation mode, the humidifier is fixed to the operation of the humidification amount of about 400 cc / h. That is, the operation mode is sequentially switched to automatic operation-manual operation / high-manual operation / medium-manual operation / low-automatic operation by pushing the selection button (30B).

According to this embodiment, the operation board (32) to which the operation electric components such as the operation switch (not shown), the selection switch (33) and the automatic operation display lamp (L) are attached is the operation unit case (25). Since it is housed inside and its operation part case (25) is connected to the upper part of the main body case (1), the operation button (30A) and the selection button (30B) can be placed on the upper part of the device, The operation can be performed in a comfortable posture, and the operability is improved. Further, the connector (37) of the lead wire (36) can be inserted into the upper wall (1A) of the main body case (1) and the bottom wall (27A) of the inner cover (27) of the operation unit case (25) that are in contact with each other. The insertion holes (39) and (41) each having a size are provided, and the insertion holes (39) and (41) are provided such that their centers are offset from each other, and the insertion holes (41) on the main body case (1) side are provided. Since the lead wire (36) is inserted and the notch (42) closed by this lead wire (36) is provided in the peripheral edge, as shown in FIG. 6, the insertion hole (39) and ( 41) can be closed by using the upper wall (1A) of the body case (1) and the bottom wall (27A) of the inner cover (27), and the notch (42) is closed by the inserted lead wire itself. Therefore, a seal member such as putty is unnecessary,
This makes it possible to save the labor of the sealing work of the insertion portion of the lead wire (36). Further, since the insertion holes (39) and (41) are large enough to insert the connector (37), the lead wire insertion operation can be performed quickly and easily.

Further, since the rising cylinder portion (40) is formed at the peripheral edge of the insertion hole (41) on the operation portion case (25) side, the upper wall (1A) of the main body case (1) and the inner cover (27) are formed. Bottom wall (27A)
Even if water soaks in between, the rising tubular portion (40) can prevent water from entering the operation portion case (25).

In addition, in the above-described embodiment, the notch (42) is provided at the peripheral edge of the insertion hole (41) on the main body case (1) side, but this notch is provided on the operation case (25) side. ), Or both edges of the insertion holes (39, 41).

(G) Effect of the Invention Since the present invention is configured as described above, the operation section can be placed on the upper part of the device, and the operability of the device can be improved, and of course the main body case and the operation part. The insertion holes provided in the case can be closed by using the contact portions thereof, and the notch for inserting the lead wire is closed by the lead wire itself, so that a seal member such as putty becomes unnecessary, and the lead wire It is possible to save the labor of sealing the insertion portion. Also, since the insertion hole is of a size that allows the lead wire connector to be inserted, the lead wire insertion operation can be performed quickly and easily.
Workability can be improved.

Also, since the rising cylinder is formed around the insertion hole on the side of the operation unit case, even if water may soak between the main body case and the operation unit case, the rising cylinder does not allow water to enter. It can prevent water from entering the operation unit case.
