This is a hot air heating device equipped with a control device.

Effect: With the above configuration, the suction port sucks in air that has been heated to some extent by solar energy, which speeds up the start-up of heating and saves energy.

In Fig. 1, 1 is the main body case of the hot air heating device, 2 is the air outlet provided in the front upper part of the main body case 1, 3 is the suction port provided in the rear part of the main body case 1, and 4 is the inlet provided in the main body case 1. 5 is a blower installed in the main body case 1; 6 is a room such as a sunroom or greenhouse heated by solar energy; 7 is a heat source device provided;
8 is a warm air heating and air conditioning room; 8 is a wall that partitions the sunroom, greenhouse, etc. room 6 and temperature heating and air conditioning room 7;
is a communication portion provided in the wall 8 facing the suction port 3.

In FIG. 2, a room 6 such as a sunroom or a greenhouse is communicated with a temperature heating and air conditioning room 7 through a duct 10, and the opening at the end of the duct 10 facing the warm air heating and air conditioning room 7 is shown. This shows an embodiment in which a hot air heating device is provided with a suction port 3.

FIG. 3 shows a block diagram of a control system for keeping the blowing temperature constant, and the duct configuration is the same as in FIG. 2. In this FIG. 3, 11 is the first
12 is a comparator that compares the signal from the first temperature detector 11 with a reference signal for keeping the blowout temperature constant; 13 is the comparator 12;
This is a control device that issues control signals to the blower 5 and heat source device 4 to maintain the blowing temperature at a constant level.

FIG. 4 shows the relationship between the hot air heating and air conditioning time and the temperature of the hot air heating and air conditioning room, where A shows the conventional example and B shows the structure according to the present invention.

FIG. 5 shows the relationship between the hot air heating and air conditioning time and the energy required for air conditioning and heating, where C shows the conventional example and D shows the structure according to the present invention.

As is clear from FIGS. 4 and 5 above, the configuration of the present invention is superior to the conventional configuration in terms of the start-up temperature and energy of the warm air heating and air conditioned room.

Figure 6 shows the switching component of the suction port.
14 is a first lid for opening and closing the suction port 15 provided at the lower front of the main body case 1 constituting the hot air heating device;
16 is a second lid for opening and closing the suction port 3 facing the end opening of the duct 10; this second lid 16 is connected to the first lid 14 via a connecting rod 17; When the second lid 14 closes, the second lid 16 closes.
opens, and when the first lid 14 opens, the second lid 16 opens.
is configured to close. 18 is a driving part that automatically switches between the first lid 14 and the second lid 16; this driving part 18 has a plunger 19;
6, and when the plunger 19 is driven, the first lid 14 and the second lid 16 are driven in conjunction with each other. Reference numeral 20 denotes a switching designation unit for switching between manual and automatic switching, and is configured as shown in FIG. 2
Reference numeral 1 designates a micro switch, and this micro switch 21 is configured so that its contact closes when the switching designating section 20 is set manually. At this time, the plunger 19 is driven to open the second lid 16 and close the first lid 14. Therefore, after that, whether the inlet is communicated with the room 6 heated by solar energy or with the warm air heating and air conditioning room 7 is determined by operating the switching section 22 provided on the first lid 14. . 23 is a second temperature detection section that detects the temperature of a portion connected to the chamber 6.

Figure 8 shows a block diagram of the control circuit that connects the suction ports and automatically switches them.

7 is a flip-flop for preventing chattering.

Now, when switching to manual mode by operating the switching designation section 20, the contact of the micro switch 21 closes,
Current flows through the OR circuit 26 to the plunger coil 28, and the plunger 19 operates to open the second lid 16 and close the first lid 14. Further, when automatic switching is performed by operating the switching specifying section 20, the contact of the micro switch 21 is opened, so in this case, the plunger 19 is automatically controlled by the signal from the comparator 24.

That is, an inlet that communicates with a hot air heating and air conditioning room in which a hot air heating device is installed is provided separately from an inlet that communicates with a room heated by solar energy,
Moreover, since a switching part is provided between this inlet and the inlet that communicates with the room heated by solar energy, for example, if the room heated by solar energy does not have enough thermal space, hot air heating can be used. By opening the suction port communicating with the air conditioned room, the heating load on the hot air heating device can be reduced. In addition, the above 2
By automatically switching the switching parts of the two suction ports, it is possible to connect the suction ports to a room heated by solar energy and a room with a smaller load among the hot air heating and air conditioning room, and as a result, This is extremely useful in terms of energy conservation.

Effects of the Invention As described above, the present invention provides the following various effects.

(1) The inlet installed in the main body case of the hot air heating device is connected to a room heated by solar energy (e.g. sunroom, greenhouse, etc.), so the excess heat in that room can be absorbed. The hot air can be effectively introduced into the heating and air conditioning room, and as a result, the temperature of the hot air heating and air conditioning room can be increased quickly with less energy.

(2) Since the configuration combines the configuration that keeps the blowout temperature constant and the configuration that connects the suction port to a room with a thermal margin, when continuously air-conditioning and heating a hot-air heating and air-conditioned room, It is quite effective in terms of energy.
