Description

  The present invention relates to a fan heater in which a heating mechanism and a fan are provided in a warm air path so that warm air can be blown.

  Conventionally, this type of fan heater is known to burn a fuel such as gas or petroleum, or to have a structure in which air heated by a heating mechanism heated by an electric heater is supplied into the room as hot air by a fan. It has been.

  That is, since the above-mentioned fan heater is used for the purpose of heating the room, the air heated by these heating mechanisms is normally discharged into the room as it is. (See Patent Document 1)

Japanese Patent Laid-Open No. 11-257753

  However, the warm air discharged from the fan heater is normally used only for heating the room where the occupants live, and other uses are not considered.

  By the way, when the temperature difference between the heated room and the outdoor space becomes large in a residence, there is a concern about the influence of heat shock on the resident. The heat shock means that when a person suddenly moves from a warm place to a cold place, the temperature difference causes a physiological stress such as a change in blood pressure or an increase in heart rate.

  On the other hand, there are hot water bottles, anchors, and the like as conventional heating devices that can be carried by a person. These are designed to be portable by storing hot water, charcoal fire, etc. in a container at the time of use.

  Thus, in order to avoid heat shock, it is conceivable to take measures such as heating in other rooms or carrying a heating appliance such as a hot water bottle or an anchor. However, it is not economical to keep the entire other space where the occupant's occupancy time is short, respectively. Moreover, in order for a resident to move a heating appliance, it is not practical, such as a cord for fuel supply or driving power supply to the heating appliance. There was a problem that complicated work such as preparing hot water or charcoal fire just before use was necessary.

  Therefore, an object of the present invention is to provide other functions such as a function of taking a heat shock countermeasure without performing a complicated operation using the above-described conventional fan heater.

  The characteristic structure of the fan heater of the present invention is that a heating mechanism and a fan are provided in the hot air passage so that the hot air can be blown, and heat is transferred from the hot air flowing downstream of the heating mechanism in the hot air passage. The heating part which receives is in the point provided.

  In other words, while maintaining a function as a conventional fan heater by providing a heating mechanism and a fan in the warm air path, a heating unit is provided in the warm air path, and from the warm air circulated downstream of the heating mechanism, Since it is configured to be able to receive heat transfer, the heated object can be heated only by storing the heated object that needs to be heated in the heating unit. Therefore, it was possible not only to warm the room but also to have a function of heating the object to be heated in the fan heater.

In the above-described configuration, it is preferable that a heat storage device is detachably provided in the heating unit. Since the heat storage device as the object to be heated is configured to be detachable from the heating unit, the heated heat storage device can be used as a portable heating device immediately after being detached from the heating unit. .
In general, anchors are used as portable heaters. However, adjustment of heat sources during use and handling after use are troublesome, and it is not very realistic to prepare them in a state where they can always be used. However, according to the above-described configuration, it is practical because the heat storage device can be switched between the use state of the heat storage device and the preparation state for using the heat storage device by simply attaching and detaching the heat storage device to and from the heating unit.

  Further, in the above-described configuration, the hot air path is formed by the fan so as to guide the warm air downward through the heating mechanism, and the heating unit is provided above the heating mechanism. Is preferred.

  The air heated by the normal heating mechanism tends to move upward because of its low density, and the upper side of the heating mechanism is easily heated. Therefore, by disposing the heating unit above the heating mechanism, heat from the heating mechanism can be efficiently received by the heating unit. In addition, since the warm air path is formed so that the hot air is guided downward by the fan via the upper part of the heating mechanism, the warm air is discharged from the lower part of the fan heater, and the heating efficiency by the fan heater is increased. Can be increased.

  In addition to the above-described configuration, a heating control unit is provided that allows switching between a first state that allows heat transfer from the combustion exhaust gas to the heating unit and a second state that blocks heat transfer. Preferably there is.

  It is desirable that the heat storage device accommodated in the heat storage device is always heated to a standby state in which it can be used. For example, depending on the long-term use of the fan heater, the heat storage device is overheated. There is a fear. In addition, in the usage state of the heat storage device and the like, since there is no heat storage device in the heating unit, it may be uneconomical from the aspect of heat utilization efficiency to continue transferring heat to the heating unit. . Therefore, when the heat storage device needs to be heated by the heating control unit, the heat storage device can be heated as a first state in which heat transfer from the combustion exhaust gas to the heating unit is allowed. In other cases, if the operation is switched to the second state in which the heat transfer is cut off, the heat storage device can be efficiently and comfortably maintained.

  Moreover, in addition to the above-mentioned structure, it is preferable that the heat storage device is provided with a temperature display unit. If comprised in this way, the user of the said thermal storage device will know from the said temperature display part whether the thermal storage device is fully heated and is in a usable state, or it is not yet in a usable state with insufficient heating. be able to. Therefore, the heat storage device user can use the heat storage device more comfortably.

  Moreover, in the above-mentioned structure, it is preferable that the heat storage device is a metal hollow container that contains a heat storage material and is portable. If comprised in this way, since the said container is a metal, the heat transmitted to the said thermal storage apparatus will be transmitted to the whole hollow container quickly, and will be in the state which can be efficiently transmitted to the said thermal storage material. In addition, the heat storage material that has received heat from the hollow container can store a large amount of heat based on the size of its heat capacity, and can maintain a comfortable temperature for a long time when using the heat storage device. become.
