Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a horticultural heater that burns kerosene to heat a house or greenhouse.

[0002]

[Prior Art]

 Conventionally, this kind of horticultural heater has been equipped with various safety devices such as an anti-earthquake fire extinguishing system, an overheat prevention system, and a power outage safety system.When any safety system operates during operation, From this, the operation is stopped and the cause of operation is displayed on the display.

[0003]

[Problems to be solved by the device]

 By the way, horticultural heaters are often used unattended, so it is rare to know immediately that the safety device has been activated. Therefore, especially when the safety device is activated in winter or at night, a situation in which the temperature falls below the control limit temperature easily occurs, which may have a great adverse effect on plants and the like. The present invention has been made in view of the above problems, and its purpose is to restart the vehicle as much as possible even when the safety device is activated, and to output a display indicating that the vehicle is being restarted. It is to provide a convenient and easy-to-use horticultural heater.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the horticultural heater of the present invention controls the combustion of the burner so as to keep the room temperature within a set control temperature range, and operates the equipment when an abnormality occurs. With various safety devices that are forcibly stopped and display means that displays the cause of operation on the display when one of the safety devices is activated, it is possible to restart operation based on the cause of operation. Determination means for determining whether or not the safety device is reset, detection means for detecting reset of the safety device, instruction means for instructing restarting based on the determination result of the determination means and the detection result of the detection means, and operation during restarting A display continuation means for continuing the display of the cause is provided.

[0005]

[Action]

 With such a configuration, even if the operation is stopped due to the operation of the safety device, in many cases, the operation is automatically restarted after that, so it is possible to effectively avoid an abnormal state in which the temperature falls below the control limit temperature. Furthermore, since the cause of operation is displayed during re-operation, it is possible to prevent recurrence of troubles after this by performing maintenance and inspection with reference to this.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a burner for burning the vaporized gas of kerosene supplied from the vaporizer 2, and 3 is a pump for pumping kerosene to the vaporizer 2. 4 is a safety device group, which is composed of a safety device such as a flame sensor 5 that monitors the combustion state from the flame current flowing in the flame, a seismic sensor 6 that detects vibration, and an overheat prevention thermostat 7, and the signals from these devices. Is input to the microcomputer 8. There are various other safety devices in fact. The microcomputer 8 displays combustion control means 9 for controlling the combustion of the burner 1 so as to keep the room temperature within the control temperature range set by the user, and when any safety device is activated, the cause of the operation is displayed on the display device 10. In addition to the display means 11 for determining, a determination means 12 for determining whether or not the re-operation is possible based on the operation cause, a detection means 13 for detecting reset of the safety device, a determination result of the determination means 12 and a detection result of the detection means 13 Based on the above, various means such as an instruction means 14 for instructing the combustion control means 9 to perform re-operation, a display continuation means 15 for continuing the display of the cause of operation during re-operation, etc. are configured. Reference numeral 16 is a solenoid that opens and closes the nozzle of the vaporizer 2.

The operation of the above configuration will be described with reference to FIGS. When the operation is started, the combustion control means 9 energizes the pump 3, the solenoid 16, etc., so that the kerosene is pressure-fed to the vaporizer 2 and becomes vaporized gas, which is jetted to the burner 1 and burned. The burner 1 freely changes the heat power according to the control output of the combustion control means 9 or repeatedly extinguishes and ignites to maintain the room temperature within the control temperature range as shown in the section A, and the display means 11 controls the control temperature. The room temperature is displayed on the display 10.

By the way, for example, when the seismic sensor 6 is turned on during combustion, such as in the section B, the combustion control means 9 detects this. Therefore, the driving is stopped urgently, and the display means 11 causes the display device 10 to output the identification code corresponding to the seismic sensor 6. After the operation is stopped in this way, the room temperature will gradually drop. However, the determination means 12 determines that the operation of the seismic sensor 6 is temporary, so that it can be restarted sufficiently, and the detection means 13 also promptly detects that the seismic sensor 6 has returned to the set state. .. Therefore, the instructing means 14 operates based on such a result, the combustion control means 11 is started, and the burner 1 is burned again. Therefore, it is possible to effectively avoid the problem that the room temperature becomes equal to or lower than the limit temperature that adversely affects the plants. It will be possible.

During the re-operation, the display 10 continues to output the previous display, that is, the identification code corresponding to the seismic sensor 6 by the action of the display continuation unit 15. If you do this, you can easily and surely know that a previous emergency stop occurred. Therefore, in addition to the operation to return the display unit 10 to the normal display, you can also focus on the cause of the operation and perform maintenance / inspection and operation of the device. The performance of the device is ensured by performing the confirmation.

The above-described embodiment is for the case where the seismic sensor 6 is activated, but the overheat prevention thermostat 7 is activated, the flame sensor 5 detects an extinguishment on the way, or a power failure safety device (not described) is activated. Even in such a case, the operation will be restarted unless a danger is expected, so the same explanation will be given. Note that, for example, once the overheat prevention thermostat 7 is activated, there is a high possibility that it will be activated again after the restart. Then, in the case where such an operation occurs frequently, it is desirable that the operation is actually prohibited depending on the number of operations. Further, although the display means 11 has been described as an example in which the temperature and the code are selectively output to the display device 10, a plurality of display devices 10 may be provided and each of them may be individually displayed. Such modifications can be appropriately made without departing from the spirit of the present invention.

[0011]

[Effect of the device]

 As described above, according to the present invention, even if the equipment is stopped due to the operation of the safety device, the operation is automatically restarted if it is judged that the equipment can be restarted sufficiently. It is possible to effectively prevent the temperature from falling below the critical temperature that affects it, and the cause of the safety device continues to be displayed during re-operation.Please refer to this to perform maintenance / inspection and operation check It has many practical effects, such as ensuring the performance of.
