BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1. FIG. 1 is a perspective view of an oil warm air heater equipped with casters showing an embodiment of the first invention, FIG. 2 is an enlarged view of the caster portion thereof, (a) shows the casters locked, (b) ) Indicates that the casters are unlocked. FIG. 3 is an enlarged sectional view of the burner portion of the oil warm air heater, and FIG. 4 is a simplified block diagram showing only the lock mechanism of the casters.

In the figure, reference numerals 2, 3 and 27 are the same as or equivalent to those of the conventional example, and therefore the description thereof is omitted. Reference numeral 29 is a main body of the oil warm air heater, and 45 is an electromagnetic driving body, which constitutes a locking means for locking the caster 27 by bringing the stopper 46 into contact with the wheels of the caster 27 when turned on. There is. Reference numeral 47 is a flame detector as a driving detecting means installed on the side of the burner head 35,
An electric current is passed through the flame generated from the burner head 35, and the combustion state is detected to detect whether or not it is in operation. Reference numeral 48 is a switch that is turned on / off in association with the detection result of the flame detector 47.

Next, the operation will be described. First, when the operation is stopped, as a matter of course, since no flame is formed from the burner head 35, the flame detector 47 detects that no flame is formed, and the switch 48 is turned off. Therefore, the electromagnetic drive body 45 is not energized, and the caster 27 is kept in the non-locked state. Therefore, in this state, the main body 29 can be freely moved.

Next, during operation, the kerosene vaporized by the burner 34 burns, and a flame is generated from the burner head 35, so that flame formation is detected by the flame detector 47, and the switch 48 is changed from the off state to the on state. Can be switched.
Therefore, the electromagnetic drive body 45 is energized, the stopper 40 contacts the wheels of the caster 27, and the caster 27
Is locked. Therefore, in this state, the main body 29 becomes immovable and is stationary on the spot. Although the oil warm air heater using kerosene as a fuel has been described in the first embodiment, a gas warm air heater using a gas as a fuel may be used, and the same effect as that of the above embodiment can be obtained.

Embodiment 2. FIG. 5 is an external perspective view of an electric stove including casters showing an embodiment of the second invention, and FIG. 6 is a simplified circuit diagram of the electric stove. Note that the external appearance and the locking means of the casters 27 are exactly the same as those of the first embodiment of the first aspect of the invention, and therefore FIG.

In the figure, 27, 45 and 46 are the first
The description is omitted because it is the same as or equivalent to that of the first embodiment of the present invention. Reference numeral 49 is a main body of the electric stove, 50 is a heater for heating which generates heat by energization, 51 is a rear reflector provided in the rear of the heater 50, and a concave reflector for reflecting the heat emitted from the heater 50 in the forward direction, and 52 is A heat sensitive device as an operation detecting means provided above the heater 50, which is made of bimetal and detects whether heat is generated by energizing the heater 50 to detect whether or not the operation is being performed. 53 is a power switch.

Next, the operation will be described. First, when the power switch 53 is turned off and the operation is stopped, the heater 50 naturally does not generate heat, so that the heat sensitive device 52 detects the non-heat generation state, and the switch 48 is maintained in the off state. Therefore, the electromagnetic drive body 45 is not energized, and the caster 27 is kept in the non-locked state. Therefore, the electric stove main body 49 can be freely moved.

Next, during the operation in which the power switch 53 is turned on, the heater 50 generates heat, so that the heat sensitive device 52 detects the heat generation state, and the switch 48 is turned on. Therefore, the electromagnetic drive body 45 is energized, the stopper 46 contacts the wheels of the caster 27,
The casters 27 are locked. Therefore, in this state, the electric stove main body 49 becomes immovable and stands still there.

In the second embodiment, the heat detector 52 is provided as the operation detecting means. However, in many electric stoves, heat is generated from the heater 50 at the same time when the power switch 53 is turned on. On / off of may be used for the operation detecting means.

[0015]

As described above, according to the first aspect of the present invention, when the operation detecting means detects that the vehicle is in operation based on the presence or absence of heat generation in the heat generating portion, the locking means locks the casters to prevent movement of the main body. As a result, it is possible to prevent actions such as moving the main body during driving, while the locking means is automatically released when the operation is stopped and the main body can be moved easily, further improving safety. The effect that can be obtained is obtained.

Further, according to the second aspect of the invention, when the operation detecting means detects that the heating heater is energized, the caster is locked by the locking means and the main body cannot be moved. Therefore, it is possible to prevent the act of moving the main body during driving, and at the same time, when the driving is stopped, the locking means is automatically released and the main body can be moved easily, so that the safety can be further improved. The effect is obtained.
