Description

An electric fan and a heater}

The present invention is a design for a heater combined electric fan that a heater is installed on the front of the fan, more specifically, a heater combined electric fan that is used as a fan at the time of detachment as a heater to be detachably installed so that the heater is installed detachably It is about.

Fans are owned by more than one household, and as life gets better, the function of air conditioners is gradually being taken away from air conditioners, but the demand is not decreasing due to the high energy consumption. It is not losing its place as an essential household appliance thanks to the research results that the cooling efficiency can be improved at low cost.

However, the fan has a disadvantage in that its utilization is inferior in the four seasons, such as our country because it is a product for the season, so now a lot of research is being done to increase its utilization, that is, not only summer One of them is a heater-use electric fan, which is intended to be operated by blowing hot wind even in winter.

Such a combined use of a fan is used to heat even in winter while using a conventional fan as it is used not only to improve its utilization, but also heat efficiency by heating convection rather than by radiation or reflected heat is particularly effective during heating. It functions as a convection type heater that sends the heated heat to the wind of the fan to improve thermal efficiency, and also to improve the temperature of the room quickly by allowing the hot air to be quickly convexed. It also helps to save energy.

The heater-use electric fan is a patent application No. 90-1220, the electric-heater combined-use fan, which is equipped with a ceramic heating element and Mr heater on the wing of the fan to blow the hot air by spraying the flame inside the wing. Since the heater is installed inside each wing, the equipment cost is high and the weight of the whole wing is increased, so the motor for rotating the blade must also be large, which is just an economically infeasible invention, and another is a utility model registration application. There is a fan with a stand and a hot fan of No. 94-20422, which allow the head of the fan to be detached from the stand to install a cooling fan device, a lighting device, and a warm air device instead of the head of the fan. It is to be able to install the device having each function in one stand. Each device detachable from the upper part of the stand is an individual device having all of its own functions. Therefore, the device does not correspond to the combined use, and there is another hot air outlet of Utility Model Registration No. 81-5310. It is a classic and inefficient structure, which is made of a blower and a heater for blowing air in the main chain body, and its structure is fixed, and various designs are impossible. There is a hot-air fan of the application 90-9740, which is, as shown in Figure 4, the horizontal rotating fan (3) is installed in the upper body (2), and also induces blowing in each window drilled on the side wall Guide vane is installed, and the storage compartment is recessed downward from the middle of the cover covering the upper body 2 from above. In the circumferential wall, a plurality of through holes 51 are drilled, and on the lower body 1, a motor 22, ON, OFF, and a shift switch plate 11 are provided. The electric heater 4 is built in the storage chamber. (4) and the motor 22 are electrically connected to the selector switch 14 and the tire 13, and the heater 4 is electrically connected to the thermostat thermistor, and the motor 22 at the time of selecting the hot air fan is It is configured to operate only when the heater 4 is heated up to a prescribed temperature '. A heater installed at the center is heated in the upper part, and a horizontal rotating fan installed at the periphery sends hot air according to the guide vane. When it is used as a heater, it can function to some extent, but as the fan has an obstacle called a heater in the center and the fan is horizontally rotated, the blowing capacity of the fan is inevitably deteriorated. As a design having a certain degree of similarity, there is an electric stove of Utility Model Registration Application No. 90-610, and a design of a combined electric fan, which is equipped with a heater at the head of the fan and reversely rotating the fan, as shown in FIG. 5. In order to blow the heat of the heater in the case of, the general head (plastic housing) of the fan is not suitable for the built-in heater, so a separate configuration is required, and the conventional fan is not blown with eggs. It is made by designing a suitable wing (pen) has the disadvantage that the efficiency of the backwind is very low.

The present invention has been made to solve the above problems, by adopting a conventional fan as it is, and provides a structure that allows the heater to be attached and detached to promote economics without affecting the blowing ability as a fan at all, the heater is Since it is located at the front end, it maximizes the effect of convection even when used as a heater, thereby exhibiting sufficient heating capacity, and by providing a structure that can additionally provide reflected heat, it has come to complete a design to minimize heat waste. Detailed description is as follows.
