Abstract

PROBLEM TO BE SOLVED: To provide an effective heater which is possible of use within a cloth or a bed or of carrying and use in the inside and outside of the housing.SOLUTION: This heater emits heat from a small and circular heater body, radiates heat from the periphery of the body by an inner fan and further allows the carry and use with its rechargeable battery system. A fan motor 4 is installed inside the heater 3 such that the motor contacts with the heater tray 1 so as to transmit the generated heat to its outside surface. The fan motor 4 is rotated to generate warm air radially and discharge warm air to the periphery of the heater tray 1 through a discharge slit 2. The heater tray 1 and a rechargeable battery tray are installed separately such that they catch a supply air current inlet path therebetween, and are held by an elastic net 21 which produces a flexible spring property by a cylindrical and centrifugally-curved form, thereby forming a contour structure taking effect of flexible restoring force.

Description

  The present invention relates to a heater that can be used in clothes, bedding, and indoors and outdoors.

  For clothes and portable heaters, fuel-type or rechargeable battery-type furnaces are well known. In addition, there are those in which a heating wire is incorporated into the clothing, and others in which warm air is blown into the clothing from an external device through a tube. As for the heater in the bedding, there are those that blow warm air into the bedding from an external device through a pipe, including those that are also used as a futon dryer.

  Fuel-type or rechargeable battery-type furnaces have a difficulty in narrowing the heat receiving part. There are vests and whole-body jackets that incorporate heating wires in the clothes, etc., but they are worn on clothes and have a lower heat receiving efficiency compared to the hood in the clothes. The rate of heat dissipation increases. A device that blows warm air from an external device through a tube tends to be troublesome to attach the external device or the tube. In addition, since air is easily heated and simultaneously cooled, heat loss in the pipe path increases. Similarly, a device that blows warm air into the bedding from an external device through a pipe causes heat loss in the pipe path, and noise from the blower is also a problem at bedtime.

  In order to solve the above problems, the present invention generates heat from a relatively small and circular heating heater body to be used in clothes and bedding, and radiates warm air from the outer periphery of the body by an internal blower. Suppose that it is a rechargeable battery and can be used in a portable manner.

  In the present invention, convenience and heat receiving efficiency are the same as those of a squirrel furnace, but the heat receiving part is much wider. Since the hot air is discharged directly from the main body without passing through the pipe, there is no heat loss in the pipe path. At bedtime, the body is relatively small and the main body including the blower is used in the bedding. Therefore, the bedding serves as a soundproofing material, and noise is reduced.

It is a side view which shows the use Example of a circular warm air heater.

  In order to carry out the present invention, first, the heating element is arranged in an annular shape. The case for holding the annular heating element is circular and emits heat from the outer surface. A blower is installed inside the annular heating element and the impeller is rotated to generate hot air radially.

  When used in clothes, the switch body is compressed by compressing the main body itself so that it can be stopped or stepped by hand search from the outside of the clothes or in the bedding. Enable switching.

  The rechargeable battery and the circuit board are housed in a case located on the opposite side of the heating element in order to suppress the adverse effects of the heat generated by the heating element or to use the remaining heat during charging on the outer surface. In addition, a suction passage of the blower is provided so as to be sandwiched between the heating element side and the rechargeable battery side to cool the internal heat generation of the rechargeable battery and the circuit board and to assist warm air heating.

  In particular, when used in bedding, a projection cover net can be attached to the main body in order to ensure safety or a hot air working range.

  The embodiment will be described with reference to the drawings. In the embodiments shown in FIGS. 1, 2, 3, 4 and 5, the heating element 3 is arranged in an annular shape, and the heating element 3 itself is a coiled heating wire, a covering. Various things such as a heating wire, a rod, or a tubular heating element are assumed. The heating element 3 is held by a circular heating element dish 1, and generates heat from the outer surface of the heating element dish 1 made of a metal plate or a heat-resistant member. A fan motor 4 is installed inside the heating element 3 so that the motor is in contact with the heating element tray 1 so as to transmit the generated heat to the outer surface. In this embodiment, the fan motor 4 is a centrifugal fan, but the axial fan or the like is not excluded by adjusting the arrangement or the like. The fan motor 4 is rotated to generate hot air radially and discharged to discharge the hot air to the outer periphery of the heating plate 1 through the slit 2.

  The heating element tray 1 and the rechargeable battery tray 11 are separately provided so as to sandwich the air supply inflow path therebetween, and are held by an elastic net 21 that has a cylindrical and curved shape in a centrifugal direction and generates an elastic spring characteristic. By forming an outer structure that exhibits expansion and contraction and temporarily pressing the outside of one of the dishes, it becomes a contracted state as shown in FIGS. 2 to 3, and when the pressing is stopped, the state shown in FIG. Try to go back. At this time, the return switch 16 installed in the rechargeable battery tray 11 is operated to switch the switch. By separately providing the heating element tray 1 and the rechargeable battery tray 11, a shrinkable state with a degree of freedom is created, and the switch can be switched even when pressed slightly from an oblique direction.

  The rechargeable battery 14 and the circuit board 15 are accommodated in the rechargeable battery tray 11 to dissipate the remaining heat during charging to the outer surface. When the circuit board 15 exceeds a predetermined temperature, heat generation is interrupted by a heater circuit incorporating a thermostat. Air supply to the fan motor 4 is performed along the inner disk 5 from the suction slit 12 to cool the internal heat generation of the rechargeable battery 14 and the circuit board 15 and to assist warm air heating.

  The outer surface of the heating element tray 1 and the rechargeable battery tray 11 is covered with a fabric 22, and in the usage example shown in FIG. 6, the main body 31 is held by a hanging strap 32 and used in a garment 41. Further, in the usage example shown in FIG. 7, the main body 31 to which the protruding cover nets 33 and 34 are attached is used in the bedding 51 in order to ensure safety or a hot air working range.

  Heating equipment such as an air conditioner and a stove is used in an open space in a living room, and a user's rate of heat reception with respect to heat generation energy is limited. In the case of local heating such as kotatsu and electric mats, the range of action tends to be limited. From the viewpoint of energy-saving heating, it is considered that minimum heating around the body in clothes and bedding is effective, and a heater that can be used indoors and outdoors is highly convenient.
