DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIG.

The heater humidifier according to the embodiment of the present invention includes an outer case 1 and a humidifying tank 2 (water tank) having an open upper part in the outer case 1. 2a is provided with a canopy 3 whose one end is pivotally supported by the outer case 1 and can be freely opened and closed.

The outer case 1 is formed in a cylindrical shape from a resin material, and houses a humidifying tank 2 via a heat insulating space 4 inside. The outer case 1 is fixed to a pedestal 5 having a circular planar shape made of a resin material.

The humidification tank 2 is formed in a cylindrical container from a stainless steel material, and has a wide-opening 2a at the upper end.

This humidifying tank 2 also has a water storage function,
There is no separate water supply tank, and water is supplied directly into the humidification tank 2 and stored as it is. Therefore, the entire water stored in the humidification tank 2 is heated. As described above, in the heater type humidifier of the present embodiment, since it is not necessary to provide a water supply tank and water is directly stored in the humidification tank 2, the number of parts is small, the configuration is simplified, and the apparatus is simplified. Compactness can be achieved.

A heater 9 is wound around the lower part of the humidifying tank 2 so that when electricity is supplied, the entire water in the humidifying tank 2 is heated to generate steam. Heater 9
Has a variable output, and its electric circuit will be described later, but can be changed to 400 W and 160 W outputs.

A first thermostat 51 and a second thermostat 53 are provided below the humidifying tank 2 and above the heater 9 at the same height from the bottom surface.

When the temperature in the humidifying tank 2 reaches a first set temperature lower than the boiling temperature, the first thermostat 51 turns off.
An automatic reset type in which the heater output is reduced in an F (off) state is used.

The second thermostat 53 stops the energization of the heater when the temperature in the humidification tank 2 reaches a second set temperature higher than the boiling temperature, and the energization once stopped is manually reset. Is used.

The first thermostat 51 and the second thermostat 53 are attached to recesses 54a and 54b, which are formed at the same height on the outer wall of the lower part of the humidifying tank 2, and are mounted on two thermostats having different operating temperatures. 5
1, 53 can be easily mounted and can be mounted at an accurate position.

The electric configuration of such a variable heater having two thermostats is shown by an electric circuit as shown in FIG. That is, in the electric circuit shown in FIG.
Alternatively, a 240 W heater 9 a and a 160 W heater 9 b are arranged in parallel with an AC power supply 50 of 60 Hz, and the 240 W heater 9 a has a first thermostat 51.
Is provided. The first thermostat 51 is configured to turn off (off) when detecting a first set temperature of 95 ° C., which is lower than the boiling temperature, and to permit current when detecting 70 ° C. or less. As a result, 2
Electric power is supplied to the 40W heater 9a and the 160W heater 9b, and when the temperature reaches the boiling temperature, the electric power can be supplied only to the 160W heater 9b.

A second thermostat 53 is disposed between the power supply 50 and the first thermostat 51. When the second thermostat 53 is turned off (turned off), 240 W is applied.
The configuration is such that neither the heater 9a nor the 160W heater 9b is energized. Therefore, when the water in the water tank runs out and a so-called empty cooking state is established, the energization is stopped. It should be noted that the second thermostat 53 is of a manual return type that does not return to the initial energized state (on state) unless it is returned by resetting a reset switch (not shown) by manual operation after being once turned off. , Malfunction is prevented.

A water supply lamp 55 and a humidification lamp 57 are connected in parallel with a heater circuit including the second thermostat 53, a 240W heater 9a and a 160W heater 9b.

The water supply lamp 55 is lit to indicate that water supply is necessary when the amount of water is less than a predetermined amount.
The humidification lamp 57 is turned on when the humidifier is operating.

In FIG. 2, reference numeral 59 denotes a thermal fuse.

The canopy 3 includes an upper cover 3a and a lower cover 3b, and the lower cover 3b is provided with an inner cover 13. Numerous holes 13a for taking in steam generated in the humidification tank 2 are formed in the inner lid 13, and packing is provided on the periphery.

A steam passage 15 is formed at the center of the lower cover 3b, and the steam taken in from the hole 13a of the inner lid 13 is supplied to the steam outlet 1 formed in the upper cover 3a.
5a. A safety valve 7 is provided in the steam passage 15 to prevent hot water from flowing out of the steam outlet 15a when the vehicle falls.

The safety valve 7 comprises a valve cylinder 17 formed in a concave shape at the center of the lower cover 3b, and a stainless steel ball 18 housed in the valve cylinder 17. A slit 17a for a steam passage is formed in the peripheral wall of the valve cylinder 17 and communicates with a steam outlet 15a formed in the upper center of the lower cover 3b.

The upper cover 3a of the canopy 3 is provided with a vapor diffusion section 19 at the above-mentioned vapor outlet 15a. The steam diffusion section 19 has a steam outlet path formed in the center thereof, and applies a derived steam to diffuse the steam, and a steam diffusion plate 23 for emitting the diffused steam radially. And a number of radial ribs 21 for guiding.

Next, the operation of the heater type humidifier according to this embodiment will be described.

Before use, first, the canopy 3 is opened, water is poured directly into the humidification tank 2 through the wide-opening 2a, and water is poured to a predetermined position, and then the canopy 3 is closed. As described above, since water is poured directly into the humidification tank through the wide-opening 2a, the supply of water is easy. In addition, since a water supply tank or the like is not required, the configuration is easy, and the inside of the humidifying tank 2 can be washed and easily cleaned.

In use, the heater 9 is connected to the power supply 50.
To supply power. At this time, the first thermostat 51 and the second thermostat 53 are in the ON state because they are in the detection state at a predetermined temperature or lower, respectively. When the power supply starts, both the 240 W and 160 W heaters 9 a and 9 b are turned on. Humidification with a total of 400 W of power when energized
The water in the tank 2 is heated. Therefore, at the time of rising, the time required to reach the boiling temperature is short, and humidification can be started quickly. At this time, the water supply lamp 55 is turned off, and the humidification lamp 57 is turned on.

When the temperature of the water in the humidifying tank 2 becomes equal to or higher than the first set temperature of 95 ° C., the first thermostat 51 is turned off, and the energization of the 240 W heater 9a is stopped. Therefore, after the water in the humidification tank 2 boils, only the 160W heater 9b is energized, and only the minimum necessary electric power is energized, thereby saving power. At this time, the water supply lamp 55 is turned off,
The humidification lamp 57 lights up.

On the other hand, when the water is exhausted and the temperature in the humidifying tank 2 becomes equal to or higher than the second set temperature of 106 ° C., the second thermostat 53 is turned off, and the 240w heaters 9a and 9
Power supply to the 60W heater is stopped. Therefore, the humidification tank 2
The water inside is not heated.

At this time, current flows through the water supply lamp 55 due to the action of the resistors 41a and 41b, but the humidification lamp 5
Since the current flowing through 7 is extremely small, the water supply lamp 55 is turned on, but the humidification lamp 57 is turned off.

When the water supply lamp 55 is turned on, the user
When water is supplied into the humidification tank 2 , the first thermostat 51 is supplied.
Automatically returns to a state where the 240 W heater is energized. On the other hand, since the second thermostat 53 does not automatically return, the user returns to the reset switch to return to the above-described initial state (rising state).

The present invention is not limited to the above-described embodiment, but can be variously modified without departing from the gist of the present invention.
