Description

  The present invention relates to a warm air heating apparatus that includes an operation panel and that starts a heating operation by pressing, for example, an operation switch among switches provided on the operation panel.

  The hot air heater has a burner inside, and burns with the burner using gas or kerosene as fuel. In addition to the burner, a blower fan is built in, and by operating this blower fan, indoor air is sucked into the heating device body from the back of the heating device body, and high-temperature combustion gas generated by combustion in the burner And the sucked room air are mixed to form warm air, which is sent out from the front surface of the heating device body to the room.

  Such a warm air heater mainly includes an operation panel on the upper surface, and a push button type operation switch is provided on the operation panel. When this operation switch is pressed, after the predetermined inspection routine is activated, the blower fan is activated first, and then the burner is ignited and warm air is sent into the room. The operation switch is also used to stop the heating operation.

  When the operation switch is pushed and operated while the hot air heater is operating, the burner is first extinguished. However, since the periphery of the burner is at a high temperature at that time, the blower fan is operated as it is, and when the periphery of the burner is cooled by the sucked room air, the blower fan is stopped.

  The operation panel is also provided with a push button type good morning timer switch. This good morning timer is an on-timer, and the operation of the hot air heater is automatically started at a preset time. Therefore, if this good morning timer switch is pressed while the hot air heater is in operation, the hot air heater will stop operating in the same way as when the operation switch is pressed, and the heating operation is automatically resumed at the set time. To do.

  By the way, if the operation switch is pressed during operation as described above, the operation is stopped. If the operation switch is accidentally pressed twice, the operation is temporarily stopped on the hot air heating device side even if the user does not notice that the operation has been pressed twice. Thereafter, it is assumed that an operation for resuming operation is performed immediately, and the subsequent control is performed.

  In such a case, since the operation opposite to the intention of the operator who finished the heating operation and put it into a resting state is performed, if the interval between the two continuous pressing operations is short, the second pressing is performed. An apparatus that ignores the operation is known (for example, see Patent Document 1).

JP 9-72538 A (paragraph 0005)

  In the above conventional system, it is effective when two consecutive pressing operations are not intended, but the second pressing operation is uniformly ignored even when consecutive pressing operations are intended. Therefore, the usability becomes worse.

  Therefore, in view of the above-described problems, the present invention has an object to provide a warm air heating device that can eliminate an operation unintended by an operator and can make the intended operation effective. .

In order to solve the above problems, a hot air heating apparatus according to the present invention detects a human body existing around a hot air heating apparatus in a hot air heating apparatus having a push button type switch for starting a heating operation on an operation panel. Provided with a human body detection sensor for notifying that the switch is pressed when the distance between the hot air heating device and the human body exceeds a predetermined distance with the switch pressed. The switch is an operation switch, and a notification stop unit that prevents notification by the notification unit when the pressing operation is performed again after a predetermined time has elapsed after the pressing operation to stop the heating operation is performed. It is provided .

  Even if the push operation to the switch is not intended, if there is a person in the vicinity of the hot air heating device, it can be stopped even if the hot air heating device starts operating unintentionally. If a person leaves the hot air heater before starting the operation, it is informed that the operation is in a starting state. If the push operation to the switch is intended, it can be left as it is, and if it is not intended, the operator can perform the stop operation.

The unintended pressing operation is almost twice in a short time. An operation that is intentionally performed can be considered as long as the operation is opened at a certain interval. Therefore, the switch is an operation switch, and notification stop means for not performing notification by the notification means when the push operation is performed again after a predetermined time has elapsed after the push operation for stopping the heating operation is performed. the provided.

  As is apparent from the above description, the present invention does not invalidate the push operation performed on the push button, so that the usability is not impaired. Further, when the pushing operation is not intended, it can be confirmed with the operator, and the subsequent operation can be appropriately performed by the operator.

The figure which shows the structure of one embodiment of this invention Diagram showing details of operation panel Flow chart showing the contents of control

  Referring to FIG. 1, reference numeral 1 denotes a gas hot air heating device (hereinafter referred to as a heating device) according to the present invention. A human body sensor 11 is attached to the front surface of the heating device 1. The human body sensor 11 measures the distance between the heating device 1 and the human body, and may be, for example, an infrared sensor described in JP-A-2003-185263 or another reflective sensor. The human body sensor 11 may continuously measure the distance between the heating device 1 and the human body. However, the human body sensor 11 has a function of detecting whether or not the human body exists within a predetermined distance with the main body 1 as the center. A thing may be used.

  An operation panel 2 for controlling the operation of the heating device 1 is provided on the upper surface of the heating device 1. Referring to FIG. 2, the operation panel 2 is provided with a plurality of push button type operation switches. An operation switch 21 is provided at the right end. When the operation switch 21 is pushed and operated when the heating device 1 is stopped, a control unit (not shown) first performs a start-up routine, first operates the blower fan, and then ignites the gas burner. As a result, warm air is sent out from the blower opening provided in the lower front portion of the heating device 1.

  Next, when the operation switch 21 is pushed again in the heating operation state, the gas burner is extinguished, and then the air fan is stopped after the vicinity of the gas burner is sufficiently cooled.

  The operation panel 2 is provided with a switch (on timer switch) 22 for operating a good morning timer as another switch. The on-timer switch 22 is for automatically starting a heating operation when a preset time is reached when the heating device 1 is pushed in a pause state. When the heating device 1 is operated and the on-timer switch 22 is pushed and operated, the burner is extinguished as in the case where the operation switch 21 is pushed and the state shifts to a resting state. Start heating operation. By the way, when the on-timer switch 22 is pushed again when the on-timer switch 22 is pushed and the timer is set, the timer is released and the normal sleep state is entered.

  Both the operation switch 21 and the on-timer switch 22 are switches provided to change from the rest state to the heating operation state.

  With reference to FIG. 3, the control when the operation switch 21 or the on-timer switch 22 is pushed will be described. The flow shown in FIG. 3 is started when the operation switch 21 or the on-timer switch 22 is pushed (S1). When either one of the switches is pressed, first, the distance between the heating device 1 and the human body is confirmed. If this distance is within 1 m, for example, even if the pushing operation itself is contrary to the operator's will, the operator can respond, so the state is maintained as it is (S2). When the human body is separated from the heating device 1 by 1 m or more, it is determined whether or not the ignition waiting state is established (S3). This ignition waiting state is a state in which the gas burner is not yet ignited, but the burner is ignited when the processing routine at that time ends. Specifically, when the operation switch 12 is pressed while the heating device 1 is in a resting state, it means a state in which an initial start routine is performed or a state in which a subsequent blower fan is operated.

  Further, when the operation switch 21 is pressed in the heating operation state and then the operation switch 21 is pressed again immediately thereafter, the state after the state where the gas burner is extinguished and the blower fan is operated for cooling is referred to. Therefore, it means that the gas burner is ignited and heating operation is started after several tens of seconds at the latest. In this state, when the human body is separated from the heating device 1 by 1 m or more, it is notified by voice that it is in the ignition waiting state (S4). If the gas burner has already been ignited and the heating operation is started, or if the operation switch 21 is pushed in the heating operation state and the fire is extinguished or has entered the hibernation state, no notification is made because the ignition is not waiting. .

  When the on-timer switch 22 is pushed, ignition is performed when the set time is reached. In this case, it is determined that the timer is set without determining that the ignition is waiting (S5). Therefore, when the on-timer switch 22 is pressed to move the human body away from the heating device 1 by 1 m or more, it is notified by voice that the timer is set (S6).

  Thus, the operation performed by the operator is notified when the human body is separated from the heating device 1 by 1 m or more, and the operator himself / herself is confirmed.

  In addition, there is a case where a pet such as a cat jumps on the heating device 1 and the operation switch 21 is pushed in a state where no human body exists within 1 m. In this case, since there is no human body, the operation is not performed by the operator. It may be determined that all pressing operations are ignored.

  In addition, when the time until the set time is shorter than, for example, 1 hour when the on-timer switch 22 is pressed, there is a low possibility that the on-timer switch 22 is pressed. Separately, a function for notifying that the timer has been set when the on-timer switch 22 is pressed may be added.

In the flow shown in FIG. 3, when the operation switch 21 is pressed, the flow shown in FIG. 3 is started. However, a predetermined time has elapsed after the operation switch 21 is pressed during the heating operation and enters a resting state. after when the operation switch 21 is depressed, there is a high possibility that pushing the operation switch 21 is intended, in which case not such to start the flow of FIG.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
