[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cold / hot air machine capable of switching between cold air and hot air.

[0002]

[Prior Art]

 Conventionally, some cold / hot air blowers have only one outlet, and the heater unit is moved slightly inside.

Further, there has also been devised a device that moves the blower mechanism up and down with respect to the main body to switch between cold and warm air (Japanese Utility Model Publication No. 2-41049).

Further, there were some cases in which cold air and hot air were switched by providing blow-out holes on the front surface and the rear surface, respectively.

[0005]

[Problems to be solved by the device]

 However, in the type that has only one blow-out hole and the heater unit is slightly moved inside, in any case, since the heater unit overlaps with a part of the blower mechanism, the blowing efficiency is deteriorated.

Further, in the type in which the air blowing mechanism is moved with respect to the main body, the heater unit is required to be twice as large as the air blowing mechanism in order to be positioned so as not to block the air blowing. Had the drawback that it would grow.

Further, in the type in which the front and rear surfaces are respectively used as cold / hot air fans, a double display is required, and it is troublesome to change the orientation of the main body back and forth when switching between cold and hot air. Was needed.

The present invention has been made in order to solve the above-mentioned problems, and it is small in size, and it is possible to sufficiently exhibit the wind efficiency of cold air and warm air while maintaining the portability. The purpose is to provide a blower.

[0009]

[Means for Solving the Problems]

 In order to achieve this object, the cool and warm air blower of the present invention, in particular, supports a heater unit on the inside, and has a first blowout hole adjacent to the heater unit and a second blowout hole separated from the heater unit. A blowout unit rotatably supported with respect to the main body is provided, and the main body is provided with blowout holes corresponding to the first and second blowout holes as a result of rotation of the blowout unit. It is characterized by having a shielding wall that substantially shields.

[0010]

[Action]

 According to the cold / hot air blower of the present invention having the above structure, the first blow-out hole is shielded by rotating the blow-out unit so that the first blow-out hole corresponds to the shielding wall. In this case, the cold air can be blown out from the second blowing hole by utilizing the cold air mechanism. Also, by rotating the blow-out unit and making the second blow-out hole correspond to the shielding wall, the second blow-out hole is blocked and the first blow-out hole is opened, so in this case, the heater unit is used. Warm air can be blown from the first blowing hole.

A sirocco fan 7 driven by a fan motor 8 is rotatably installed inside the blowout unit 3. The fan motor 8 is fixedly arranged on the upper surface of the support plate 1B above the upper body 1. Around the sirocco fan 7, there is provided a semi-arcuate shield wall 9 whose base end is integrally erected from the support plate 1B of the upper body 1. The structure is such that the wind generated from the sirocco fan 7 is concentrated and blown only in the half of 180 ° of the circumference of the fan, which is 180 °.

A water tank 12 that is detachably attached and that can store a certain amount of water 11 is provided below the inside of the lower body 2 that has an air intake hole 10 on the upper circumference. Four casters 13 are attached to the lower side of the water tank 12 so that the whole body can be moved by the casters 13. Further, a pump 15 driven by a pump motor 14 fixed to the upper center of the lower body 2 is provided so as to be located at the bottom of the water tank 12, and the water 11 in the water tank 12 is transferred to the inner side of the upper body 1. A pipe 17 for supplying water to a cylindrical water filter 16 concentrically attached to the is connected to the pump 15. In addition, a notched mud 18 is provided in one upper portion of the lower body 2. The display of the water level gauge 19 for displaying the amount of the water 11 in the water tank 12 is displayed by rotating the float 19A floating on the water 11 in the water tank 12 around the uniaxial line by changing the height. It has a structure that can be confirmed through the mud 18. Further, the skirt portion of the lower main body 2 is provided with an operation button 21 which is interlocked with a switch on the electronic board 20 fixed to the back side thereof.

Further, a handle 22 is fitted in two places on the outer periphery of the upper body 1, and a finger can be put in the handle 22 to carry it. Further, summer and winter indicators 23A and 23B are printed on the upper surface of the blowing unit 3a in correspondence with the first blowing hole 5 and the second blowing hole 4, respectively.

Next, the electronic circuit will be described with reference to FIG. 4. First, when the summer / winter changeover switches 24A and 24B are set to the summer side, the air volume changeover switch 25 turns off, weak, and strong. The OFF state, the weak wind, and the strong wind can be selected depending on the set, and the fan motor 8 and the pump motor 14 are driven. When the summer / winter switching switch 24 is set to the winter side, the set switch 26 fixed to the upper end of the upper body 1 of FIG. There is a set switch 27 which is rotated with respect to the main body 1 and comes into contact with the set switch 26 at the same time when it is set on the winter side. When these are turned on, the heater unit 6 operates, and The fan motor 8 also operates. At this time, the pump motor 14 does not operate. Even if the set switch 28 having both terminals of the set switch 26 and the set switch 27 is erroneously operated and the summer / winter changeover switch 24 is set to the winter side, the blowout unit 3 is set to the winter side. Unless you have not done so, there is no concern that the heater unit 6 will operate.

Next, the operation of the present invention will be described with reference to FIGS. 1 to 4. First, when the fan is used as a warm air fan, the summer / winter selector switch 24 is set to the winter side, and further, the blowout unit. Set by rotating 3 so that the winter side is facing you. As a result, the first blow-out hole 5 faces the front and the second blow-out hole 4 is shielded by the shielding wall 9. At this time, at the same time, the set switch 26 and the set switch 27 come into contact with each other, and the set switch 27 is turned on. If the air volume changeover switch 25 is set weakly or strongly in this state, the heat of the heater unit 6 is sufficiently applied. The accumulated hot air comes out from the blowout holes. At this time, the pump motor 14 is not driven, and even if the water 11 is accidentally left in the water tank 12 or left in the water tank 12, the water is not supplied to the water filter 16. The effect of heat of vaporization is not given.

Next, when the fan is used as a cold-air fan, the summer / winter selector switch 24 is set to the summer side, and further, the blow-out unit 3 is set so that the summer side is in front, so that the blow-out is performed. The heater unit 6 connected to the unit 3 is hidden behind the shielding wall 9, and the set switch 28 is also turned off. In this state, when the air volume switching switch 25 is set to weak or strong, the water 11 stored in the water tank 12 is passed through the pipe 17 by the pump 15 driven by the pump motor 14, and the upper water It is sent to the filter 16 and permeates the entire water-supplying water filter 16.

The air sucked into the main body from the air intake hole 10 by the fan motor 8 passes through the gaps between the fibers of the water filter 16 and is absorbed by the heat of vaporization of the water contained in the water filter 16. The air is cooled to 2 to 5 ° C. and is blown out from the second blowing hole 4 in the head of the main body. At this time, since the heater unit 6 is hidden behind the shielding wall 9 as described above, there is no possibility of obstructing the flow of air, and it is possible to efficiently blow out cool air.
