Abstract

PURPOSE: To keep a user from feeling a sort of cool air when the stored amount of heat of a heat storage material is limited by preventing erroneous operation with easier setting of an ON timer and an OFF timer to reduce energy loss when the heat storage material is left alone being energized. CONSTITUTION: ON timer setting possible time is made longer than the time required for the storing of heat and moreover, OFF timer setting possible time shorter than the ON timer set time to allow a heat storage material to store heat sufficiently, which facilitates the timer setting operation to eliminate erroneous operation. When the operation of energizing a heater 3 for heat storage is left alone, a control section 4 stops the heater 3 for heat storage after a specified time passes thereby preventing energy loss. When the heat storage material radiates heat to lower the temperature of warm air, the control section 4 stops a blowing section 3a for heat radiation thereby keeping a user from feeling a sort of cool air.

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

As shown in the figure, a warm air heater 2 for generating warm air and a warm air blower 2a are provided in the main body case 1, and a heat storage heater 3 is provided in a heat storage material 23 as a heat storage device.
A heat-dissipating blower unit 3a for blowing air to the heat storage material 23 is provided.
Warm air heater 2, warm air blower 2a, heat storage heater 3,
The heat-dissipating blower unit 3 a is controlled by the control device 4. The control device 4 has an operating section 5 for performing an input operation, a microcomputer 10 for receiving an input signal from the operating section 5 and providing an output signal to the switch means 6-9, a display section 11 for displaying an operating state, and a power supply circuit 12. Consists of. The switch means 6 to 9 control the energization of the warm air heater 2, the heat storage heater 3, the warm air blowing portion 2a, and the heat radiation blowing portion 3a, respectively. The power supply circuit 12 supplies power to the switch means 6 to 8, the microcomputer 10 and the display unit 11. The operation unit 5 includes an operation switch 13 and a heat storage switch 1
4, an off timer setting switch 15, an on timer setting switch 16, and an on timer time variable switch 17 are provided. The display unit 11 includes a blower operation display unit 18, a heat storage operation display unit 19, an ON timer time display unit 20, an OFF timer time display unit 21, and a heat storage state display unit 22.

In the above structure, when a signal is input from the operation switch 13 to the microcomputer 10, the microcomputer 10 energizes the warm air heater 2 and the warm air blowing section 2a to turn on the blowing operation display section 18. , Normal warm air operation.

Next, when setting the timer, when setting the on-timer first, the on-timer setting switch 1
When 6 is pressed, the microcomputer 10 first displays the incoming timer time of 8 hours on the incoming timer time display section 20. When the user wants to change the timer time, the input timer time variable switch 17 can select a time from 3 hours to 24 hours, and the input timer time can be set according to the user's preference.

The reason why the turn-on timer is set to 3 hours or more is that the time required for the heat storage of the heat storage material 23 is about 3 hours, and the heat storage capacity of the heat storage material 23 is sufficiently exhibited. For example, when it is desired to set the ON timer and heat storage at the same time, the heat storage switch 14 may be input after setting the ON timer. When the heat storage is desired to be used after 8 hours, the heat storage heater 3 is stopped for 5 hours out of 8 hours. However, the switch means 7 is energized to the heat storage heater 3 for the remaining 3 hours, and after 8 hours, the operation can be started in a state where the heat is sufficiently stored.

Next, when setting the off timer, when the off timer setting switch 15 is pressed, the off timer time display section 21 is displayed from the microcomputer 10. In the case of the present embodiment, the off timer time of 1 hour is displayed. Is set. For example, when the heat storage switch 14 is pressed by setting the ON timer setting time to 6 hours and the OFF timer setting time to 1 hour, the first 1 hour is the OFF timer operation, and the warm air heater 2 and the warm air blowing unit are operated. 2a is energized to generate warm air, but after 1 hour, it will be the on timer operation.
For the time, the heat storage heater 3 is in a stopped state, and the heat storage heater 3 is energized to sufficiently store heat in the heat storage material 23 for the next 3 hours, and hot air is generated 6 hours after the start of setting.

Thus, according to the first embodiment of the present invention,
The turn-on timer can be set longer than the time required for heat storage in the heat storage unit to fully demonstrate the heat storage capacity of the heat storage material, and the turn-off timer settable time can be set shorter than the shortest time that the turn-on timer can set. Since it can be clearly distinguished, operability is improved, and it is possible to prevent an unsafe use state due to an erroneous operation.

Although the off timer time is fixed to 1 hour in this embodiment, it may be changed to 1 hour or 2 hours if it is shorter than the set time of the on timer.

Next, a second embodiment of the present invention will be described with reference to FIG.
-It demonstrates, referring FIG. The same components as those in the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

As shown in the figure, the temperature detecting means 24 is arranged near the heat storage material 23, and the temperature detecting means 24 and the notifying means 25 are connected to the microcomputer 10.

In the above structure, when a signal is input from the operation switch 13 to the microcomputer 10, the microcomputer 10 energizes the warm air heater 2 and the warm air blowing section 2a, and the blowing operation display section 18 is turned on. Normal warm air operation is used. Next, when a signal is input to the microcomputer 10 from the heat storage switch 14, the microcomputer 10 stops energizing the warm air heater 2 and the warm air blowing unit 4, energizes the heat storage heater 3, and the air blowing operation display unit 18 Is turned off and the heat storage operation display unit 19 is turned on to start the heat storage operation. In addition, the heat storage state display unit 22 includes a temperature detecting unit 24.
Lighting is controlled by a signal from. That is, when the temperature detected by the temperature detecting means 24 reaches the first reference temperature T1, the microcomputer 10 determines that the heat storage amount is full, and the heat storage heater 3 is de-energized. Next, when the temperature detected by the temperature detecting means 24 reaches the second reference temperature T2, the heat storage heater 3 is energized again. If there is an input from the heat storage switch 14, the heat storage heater 3 is de-energized, the heat storage operation display unit 19 is turned off to stop the heat storage operation, the heat radiating blower unit 3a is energized, and the blast operation display unit 18 is lit. Then, the heat storage stored in the heat storage material 23 is released all at once. However, when there is no input of the heat storage switch, that is, when the transition to the air blowing operation is forgotten, the microcomputer 10 informs the buzzer when the warming operation is interrupted and S1 time elapses from the start time as shown by the solid line in FIG. While the means 25 is driven, the heat storage heater 3 is forcibly deenergized.

Thus, according to the second embodiment of the present invention,
When the heat storage operation is left for a long time, the heat storage operation can be forcibly stopped, so that energy waste due to the heat retention operation of the heat storage heater can be prevented.

Next, a third embodiment of the present invention will be described with reference to FIG.
-It demonstrates, referring FIG. The same components as those in the first and second embodiments are designated by the same reference numerals and detailed description thereof will be omitted.

As shown in the figure, the warm air temperature detecting means 26 is installed at the outlet of the air flow path provided with the heat storage material 23 and the heat radiating air blowing portion 3a, and the microcomputer 10 inputs to the warm air temperature detecting means 26. Receiving a signal, radiating fan 3a for heat dissipation
The switch means 9 is controlled.

In the above structure, when the heat storage switch 14 is operated after the heat is stored, the heat radiating blower section 3a is energized, the heat stored in the heat storage material 23 is gradually radiated, and the warm air temperature is gradually lowered. At this time, the warm air temperature detecting means 26 detects the heat storage material 2
The temperature of the warm air released from 3 is detected. The microcomputer 10 reads the signal from the warm air temperature detecting means 26, and for example, if the warm air temperature is 50 ° C. or higher, the heat radiation fan unit 3
A is continuously operated, and when the temperature of the hot air becomes lower than 50 ° C., the operation is stopped so that a feeling of cold air is not given.

Thus, according to the third embodiment of the present invention,
When the temperature of the heat storage material 23 becomes low, the heat-dissipating blower unit 3a is stopped, so that it is possible to prevent the user from feeling a cold wind.

In this embodiment, the temperature of the hot air from the heat storage material 23 is detected by the hot air temperature detection means 26 provided at the discharge port of the air passage, but the temperature detection means 24 for detecting the temperature of the heat storage material 23 is used. By also controlling the heat-dissipating blower unit 3a, the same function and effect can be exhibited without increasing the number of temperature detecting means.

[0035]

As is apparent from the above embodiments, according to the present invention, the set time of the ON timer is set to be longer than the time required for heat storage, and the set time of the OFF timer is set shorter than the shortest set time of the ON timer. As a result, it is possible to provide a heat storage type electric hot air blower which has a sufficient heat storage time, has an effect of easily setting a timer and reducing erroneous operations.

Further, even if the heat storage operation is set but the heat release operation is forgotten, the heat storage heater can be stopped after a predetermined time to provide a heat storage type electric air blower having an effect of preventing energy waste. .

Further, by detecting the temperature of the heat storage material or the temperature of the hot air from the heat storage material and stopping the operation of the heat radiating blower when the heat storage amount decreases, the effect of not giving the user a feeling of cool air is provided. A certain heat storage type electric air blower can be provided.
