Description of the Related Art Conventionally, a blower has a function of generating warm air and drying a humid object, for example, a hair dryer for drying hair, a futon or a dryer for drying humid articles and the like. Are known. In these dryers, a motor is provided in an air passage in the housing so that air flows from the other intake port toward the opened discharge port through the inside of the cylindrical housing that is opened at one end as a discharge port. A rotating fan was provided.

[0003] For example, in the case of a hair dryer, usually, a fan driven by a motor in a cylindrical housing and a heater for turning air blown by the rotation of the fan into warm air are provided. Was blown toward the hair from the air outlet to dry the wet hair.

[0004]

However, conventional hair dryers and dryers for drying articles are designed to blow warm air toward the object to be dried, and are particularly suitable for women and young people with long hair. If it takes a long time to dry the wet hair, the outlet is brought close to the object to blow hot air. However, if the outlet is too close, hot air will be directly blown on the object to be dried.In particular, the air flowing around the outlet will be stored over a long period of use, and the object to be dried will be heated to a high temperature. It was dangerous. In addition, when the hair is partially bundled and set in a long shape, the set is likely to be disturbed if hot air or blows out the bundled hair.

[0005] The present invention solves the above-mentioned problems, and can be used safely by blowing air without obstructing the flow of air even when one opening is brought close or closed to an object. It is intended to provide a blower.

[0006]

A blower according to the present invention has the following configuration to solve the above-mentioned problems. That is, a blower in which a blower generating unit and a main circulation unit through which the air supplied from the blower generator is circulated are disposed, and the main circulation unit is formed in a tubular shape with both ends opened. A connection for supplying air near an inlet side or an outlet side of the main circulation unit between the air circulation unit and the main circulation unit; A passage is provided.

[0007] The blower blows the air to the vicinity of the inlet or outlet of the main circulation section by the blower generating means. Regarding the flow of air in the main circulation portion, since the air supplied to the inlet side or the outlet side flows from the vicinity of the inlet side to the outlet side irrespective of both open ends, the article is brought closer to the inlet side of the main circulation portion. It is not affected by the air flow even if it blocks or blocks. That is, for example, in a case where the blower is a hair dryer, after the hair is inserted into the main circulation section, even if the opening on the entrance side is brought extremely close to or closed by the head, the air blown to the hair is The flow will be smooth without disturbance.

[0008] Further, a heat source means is disposed in the main circulation section, and the air circulated in the main circulation section is heated to generate hot air so that the drying object can be inserted into the main circulation section. If, for example, the object to be dried can be dried, for example,
It can be used as a hair dryer or a dryer in a dryer.

[0009] If the outlet of the main flow portion is reduced in diameter, the pressure of the air blown out from the outlet of the main flow portion can be increased.

If an abnormality occurs in a supply port or a heat source portion in the main circulation part, if the main circulation part is configured to be dividable along the axial direction, maintenance can be easily performed by dividing and opening the inside. Can be performed.

Further, the connection passage is formed so as to branch into two branches toward an inlet side and an outlet side of the main flow portion, and at a branch point of the connection passage, air supplied from the air blowing means is provided. If the switching valve is arranged so that the air is supplied in either one of the inlet side and the outlet side, by sending air to either one of the connection passages, the air flow in the main circulation part is reduced. The direction can be changed. As a result, air can be blown to the object in the main distribution section,
