Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hot air wagon used in bedrooms and the like.

In general, each room in a house has come to have a different characteristic function.

In addition, there is a growing demand for heating equipment that matches each room.

Traditionally, bedrooms have been equipped with numerous devices such as electric hot air fans, electric blankets, heaters such as electric stoves, alarm clocks, and heating equipment, and these have often been used in combination. The outlet plugs of each of the plurality of devices described above were connected to the outlet in the nearest room. As a result, there were many power cords lying on the floor in the dark, which was dangerous.

If you try to use the timer to operate the heater in order to wake up comfortably, you will have to set the timer to a suitable time earlier than the time you woke up to warm up the room, making it difficult to use. It's bad.

The present invention relates to a warm air wagon that can be moved to a bedroom, etc. for individual heating in a familiar place, and is easily moved to a nearby place by installing a plurality of connectors that can be connected to four other devices and a commercial power source. Along with the timer function, clock function and buzzer,
To provide a warm air wagon which has an alarm function such as lighting, can automatically determine the start time of a heater and an alarm time, and is excellent in usability and comfort.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall block diagram showing the entire system of the hot air wagon of the present invention.

When the operating section 1 selects stop/timer operation, the microcomputer inputs the time base (C, P) and has a clock function, and the timer time registered by the user. The alarm level variable unit 22 is started at a time when a predetermined time is subtracted from the power supply), or the hot air fan 6 is started at a time when an arbitrary time is subtracted from the operating unit or thermo circuit described above. A main control section 19 that inputs a signal and determines the content, a hot air fan drive section 2o, a time display section 21 made of a fluorescent display tube or liquid crystal, etc., and a notification level variable section that changes the notification level of the notification section 23. It consists of 22. Note that the notification level variable section 22 sequentially outputs the output of the microcomputer 19 from the time when a predetermined time is subtracted from the timer registered by the user, so the notification level is set according to the signal content. There is.

Is Figure 2 a wagon in the whole warm air wagon? I controller 10
This is an electric circuit diagram in which 1 block is made into one block, and the numbers h and 1 in Fig. 1 indicate the same contents.

Next, the operation will be explained using FIGS. 1 and 2.

When the power supply connector 1' is connected to the commercial frequency power supply 1, the six-page microcomputer 19 operates. An operating section 1 for selecting continuous operation, stoppage, and timer operation of the hot air fan 5 is connected to the input of the microcomputer 19, and the hot air fan drive section 20 is controlled according to the state. In other words,
If the operation unit 17 is in the continuous operation position, the hot air fan drive unit 2o
is operated, the switch 7 is closed and the hot air fan 6 is operated.

At this time, assuming that no other equipment is connected to the connectors 3 and 4, the output of the current detector 2 is zero, the current determination circuit determines that the current is zero, and the current control unit 6 Control it to reach its full potential. When an electric stove or the like is connected to the connector 3, a current flows through the current detector 2, the current judgment circuit 11 judges the current value, and adjusts the current so that it is below the maximum allowable current value of the commercial frequency power supply 1. Control unit 6
is operated to reduce the current of the hot air fan 5. Further, when the current flowing through the connector 3 disappears, the current flowing through the hot air fan 6 is increased.

In other words, since the allowable current of the hot air fan=maximum allowable current of the commercial frequency power source - the current flowing through the connector, if the current flowing through the connector is known, the current of the hot air fan that should be restricted can be determined.

As described above, dangers such as heat generation due to overcurrent can be prevented.

Next, the specific circuit and snow operation of the wagon controller 1o shown in FIG. 3 will be explained. In this figure, the same numbers as in FIG. 1 indicate the same contents.

The current determination circuit 11 inputs the signal of the current detector 2, rectifies it with a rectifier 111, and outputs a voltage V via a voltage comparator 112.
By obtaining i and comparing it with Vrefl and Vref2, the current level can be determined. For example, Vref
1 is set to a current of 4 amperes, and Vref2 is set to a voltage corresponding to a current of 8 amperes. Also,
The maximum allowable current of the commercial frequency power supply shall be 12 amperes. Then, Vi≧Vref1°Vi (If Vref 2, the current i is in the range of 4 amperes to 8 amperes, but the hot air fan current should be set to 4 amperes or less. The output becomes high and the relay 116 is activated.The output of the voltage comparator 114 is low and the relay 116 is not activated. The above is an example of using a relay, but it goes without saying that even more detailed control can be achieved by increasing the resolution of current detection.16
1 is a voltage comparator located within the thermo circuit 16.

FIG. 4 is a diagram illustrating the timer operation performed by the main control section 19. An example in FIG. 4 shows a case where the warm air fan 6 and the notification section 23 are operated by a timer, and the timer time in this case is set to e:oo. The hot air fan 6 is shown to be powered on at time TH, which is a predetermined time (30 minutes in this example) subtracted from the set timer time (6:oo). Notification department 2
3 starts the notification at time TK, which is a predetermined time (6 minutes in this example) subtracted from the set timer time (S:OO), and the notification level increases as time passes. It shows that the notification level is increasing and the notification level reaches the maximum at the time of the timer. Also, the connection device 4 is the same as the hot air fan 6! It is possible to perform the following actions.

As described above, according to the present invention, (I) the timer operation of the warm air fan is easy to use because an appropriate operation start time is determined simply by setting the wake-up time.

In addition, the living space is in a comfortable state at the time of waking up, allowing you to wake up feeling refreshed.

(11) For the timer operation of the notification function, simply set the wake-up time, and the appropriate operation start time will be determined so that the notification sound will be maximum at the wake-up time, and the notification level will increase as time passes, so you can avoid oversleeping, etc. You can wake up feeling refreshed without worrying about it.

(110) The hot air wagon of the present invention can be easily moved to a nearby location, and the power cords of other devices are connected mainly to the hot air wagon, so the power cords can be prevented from being on the floor. safety.

It has excellent usability and comfort.
