It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In order to solve the problems that the existing commercial household desk-top fan heater is large in size and inconvenient to use and store, an embedded fan heater with a brand-new design is shown in figures 1 to 4. The fan heater 1 is arranged below a cabinet 2 for use. When a user has a heating or drying demand, a heat source formed by the embedded fan heater 1 is arranged below a room, and the heat gradually rises upwards due to low hot air density, so that heat brought by the hot air can be uniformly distributed in the room. The user who feels the shank is cold easily also can have more comfortable warm braw experience. In particular, the fan heater 1 comprises a housing 10. The housing 10 is integrally enclosed by a face plate 11, an upper cover 24 and a bottom cover 14. The panel 11 is embedded with the baffle 3 under the cabinet 2 and fixed by bolts at both sides of the panel 11. The panel 11 is provided with an air supply port 15 that opens into the room and supplies air into the room. A heater 13 and a cross flow fan 12 are provided in the casing 10. The cross flow fan 12, the heater 13, and the panel 11 are arranged in this order in the air blowing direction. The air heated by the heater 13 flows into the room from the air supply outlet 15 on the panel 11 under the action of the cross flow fan 12, so as to achieve the heating or drying function. The whole fan heater 1 is combined with the baffle 3 below the cabinet 2, the appearance is simple, indoor decoration is not easy to damage, and meanwhile, indoor space can be saved.
In order to achieve high heating efficiency and blowing efficiency, the heater 13 is also specifically designed in this embodiment. The heater 13 includes a heater main body. The heater body includes multiple layers of mica electrical heating plates 22 arranged in parallel and equidistant along the height of the heater body. As shown in fig. 3, in the present embodiment, the heater body includes four layers of mica electric heating sheets 22 arranged in parallel and along equal distance, wherein the electric heating wires 23 are wound on the two middle layers of mica electric heating sheets 22. In general, the heater body extends along the extending direction of the baffle 3, and the height of the heater body formed by the layers of mica electric heating sheets 22 is consistent with that of the air supply opening 15, so that a larger heat exchange area is provided as much as possible, and the air in the shell 10 is fully contacted with the heater body.
An air guide part 21 is arranged between the heater 13 and the panel 11, and the cross section area of the air guide part 21 along the air supply direction is increased in sequence. The internal air duct of the built-in type warm air blower 1 will be described with reference to fig. 3 and 4. Three groups of air return ports are arranged on the panel 11 around the air supply port 15, and comprise an air return port 17 arranged above the air supply port 15 and air return ports 16 arranged at two sides of the air supply port 15. Return air openings 16, which are open on both sides of the supply opening 15, are also located on both sides of the housing 10 to guide the return air around the entire housing 10, which is more air-friendly. The top wall and the side wall of the upper cover 24 of the casing 10 are both provided with air inlet grilles 25, and similarly, the bottom cover 14 of the casing 10 is also provided with air inlet grilles 26 to fully ensure enough air flowability. As shown in the figure, the air flowing in from the air return inlet enters the casing 10 under the action of the cross flow fan 12 in the air return direction represented by the black arrow a and the air supply direction represented by the white arrow B, and is fully contacted with the electric heating element in the heater 13 for heating, and then is sent out from the air supply outlet 15 on the panel 11 embedded with the baffle 3, so that the warm air effect of rapid heating and full flow is achieved.
The cross-flow fan 12 and the heater 13 in the embedded warm air blower 1 can work independently or simultaneously, thereby providing three functions of cold air drying, warm air drying and heat supply for users. Specifically, the panel 11 is provided with a first switch 19, a second switch 20, and a third switch 18. The first switch 19 is used for driving the cross flow fan 12 to start and stop; the second switch 20 is used for driving the heater 13 to start and stop, and the third switch 18 is used for driving the cross-flow fan 12 and the heater 13 to start and stop simultaneously. In addition to connecting the contacts of the switch in the power circuit of the cross flow fan 12 and the heater 13 to control the cross flow fan 12 and the heater 13, the switch signal can be output through the output port of the single chip to start and stop the cross flow fan 12 and the heater 13, or to start and stop the heater 13 and the cross flow fan 12 at the same time.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
