Description

  The present invention relates to a heater that can be installed and used at any place in a room and can also be used as a means for preventing condensation on a glass window.

  Conventionally, various types of heaters for draft countermeasures near windows in winter have been proposed. For example, there is a “dew condensation prevention heater” described in Patent Document 1. This "anti-condensation heater" has a plurality of strip-like heating elements arranged in parallel via a gap, and both ends are fixed to a portable frame with the longitudinal direction set in a horizontal direction. One of the opening edges along the longitudinal direction of the body gap is an air inlet and the other is a hot air outlet.

  On the other hand, although it is not an appliance for indoor heating, there is a “warm air dryer” described in Patent Document 2 as a related to the present invention. This "warm air dryer" is a dryer main body equipped with a motor-driven blower and a heating source, and a tare capable of dispersing and discharging hot air via a bellows tube. The warm air fed from the dryer main body via the bellows tube is dispersed and discharged through a tare, thereby being used as a means for drying a futon or clothing.

Japanese Patent Application Laid-Open No. 2003-106677 Japanese Utility Model Publication No. 54-48465

  In the “dew condensation prevention heater” described in Patent Document 1, the belt plate-shaped heating element is heated to about 60 ° C. during operation, so care must be taken not to directly touch people, pet animals or curtain fabrics. Therefore, it is not easy to use, and a control member for preventing an excessive temperature rise is also required for the apparatus main body. Therefore, the number of parts increases, manufacturing becomes complicated, and cost increases.

  On the other hand, in the case of the “warm air dryer” described in Patent Document 2, there is no problem even if a futon or clothing touches the tare directly, but it is practical to use it as a heating measure in the room or as a draft countermeasure near the glass window. It is impossible.

  The problem to be solved by the present invention is to provide a heater that can prevent drafting in the vicinity of a glass window in winter and has an indoor heating function.

  The heater of the present invention is a tubular body formed of hot air generating means and a breathable material connected to the hot air generating means for introducing and releasing hot air supplied from the hot air generating means. And an expansion / contraction part provided on at least a part of the cylindrical body.

  With such a configuration, it is possible to introduce the warm air supplied from the warm air generating means into the cylindrical body and release the warm air through the air-permeable material constituting the cylindrical body. If the cylindrical body connected to the wind generating means is arranged in the vicinity of the glass window and the hot air generating means is operated, the warm air released from the cylindrical body prevents the draft from occurring near the glass window in winter. be able to. Moreover, since warm air can be discharged from almost the entire surface of the cylindrical body, an indoor heating function is also exhibited.

  Here, at least one of an airflow deflecting means for changing the traveling direction of the hot air or a pressure increasing means for blowing out the hot air in an increased state can be provided in the cylindrical body.

  When the airflow deflecting means is provided, it is possible to avoid the uneven distribution and drift of the hot air in the cylindrical body by changing the traveling direction of the hot air according to the use state, and almost the surface of the cylindrical body Since warm air can be discharged uniformly from the entire surface, the heating function can be enhanced.

  On the other hand, when the pressure increasing means is provided, the pressure of the warm air applied to the inner peripheral surface of the cylindrical body is made uniform, and the warm air that has become a uniform air flow is discharged from the entire surface of the cylindrical body into the room. Since it comes to be supplied, heating efficiency further improves. As the pressure increasing means, for example, technical means such as increasing the output of the hot air generating means can be adopted.

  Here, as the airflow deflecting means, airflow diffusing means for guiding the warm air supplied from the warm air generating means to the inner peripheral surface of the cylindrical body may be provided. With such a configuration, the warm air supplied from the warm air generating means is a warm temperature with little heat loss from the surface of the cylindrical body in a state where it spreads over the entire peripheral surface portion of the cylindrical body by the induction action of the air flow diffusing means. Since it is discharged into the room as wind, the draft prevention effect and the room heating effect are improved.

  Further, as the air flow diffusing means, a flow path for blowing the warm air in a twisting direction with respect to the axial center of the cylindrical body can be provided in the cylindrical body. With such a configuration, the hot air supplied from the hot air generating means to the cylindrical body forms a hot air swirl flow that stably flows along the inner peripheral surface of the cylindrical body. Then, warm air with little heat loss is discharged into the room from the entire surface of the cylindrical body, and the draft prevention effect and the heating effect are further improved. If the hot air swirl flow is unstable, the hot air discharged from the surface of the cylindrical body may become non-uniform and the heating efficiency may be reduced, and it may not be possible to prevent window condensation or draft.

  On the other hand, if the cylindrical body is configured to be able to stand in the vertical direction, warm air can be discharged over the entire 360 ° range centering on the cylindrical body, so that the heating effect of the entire room is greatly increased. To improve.

  Moreover, if an electroluminescent body is provided in the cylindrical body, the function as a lighting fixture is also exhibited, so that convenience is improved.

  Furthermore, if the tubular body is configured to be stored in the hot air generating means, the storage space when not in use can be reduced.

  According to the present invention, it is possible to prevent a draft from occurring near a glass window in winter and to provide a heater having an indoor heating function.

  Based on FIGS. 1-6, 1st embodiment of this invention is described. As shown in FIG. 1, the heater 10 of the present embodiment is connected to the hot air generating means 11 and the hot air generating means 11 for introducing and releasing the hot air supplied from the hot air generating means 11. The cylindrical body 12 and the expansion / contraction part 12b provided in the part except the base end part 12c of the cylindrical body 12 are provided. The stretchable portion 12b of the cylindrical body 12 is formed of a sheet-like breathable material 12a, and a grip 12e that can be gripped by hand when the stretchable portion 12b is stretched is provided at the distal end portion 12d.

  An air filter 14, an electric fan 15, and a heater 16 are disposed in this order from the air suction port 11 a side in the warm air generating means 11, and an air flow diffusion means is provided in the base end portion 12 c of the cylindrical body 12. A deflecting member 13 for changing the traveling direction is provided. A plurality of pedestals 17 for holding the expansion / contraction part 12b in a horizontal state on the floor surface F are attached to the lower surface side of the expansion / contraction part 12b of the cylindrical body 12.

  As shown in FIG. 1A, when the heater 10 is placed on the floor F in the room and the electric fan 15 and the heater 16 are operated, the warm air passes through the air filter 14 from the air suction port 11a. The air sucked into the generating means 15 is heated by the heater 16 to be warmed into the cylindrical body 12. The warm air introduced into the cylindrical body 12 passes through the deflecting member 13 at the base end portion 12 c, thereby changing the air flow traveling direction and flowing toward the distal end portion 12 d of the cylindrical body 12. As it continues, it passes through the breathable material 12a constituting the cylindrical body 12 and is released into the room as warm air.

  Therefore, as shown in FIG. 4, the tubular body 12 connected to the hot air generating means 11 is placed on the floor surface F near the glass window W in a stretched state, and the hot air generating means 11 can be operated. For example, the warm air released from the cylindrical body 12 blocks the intrusion of cool air from the outside in the vicinity of the glass window W in winter, and can prevent the generation of drafts. Moreover, since warm air can be discharged | emitted from the substantially whole surface of the expansion-contraction part 12b of the cylindrical body 12, in addition to the draft prevention function mentioned above, an indoor heating function is exhibited.

  As shown in FIGS. 1 and 2, a drift member 13, which is an air flow diffusing means, is disposed in the proximal end portion 12 c of the cylindrical body 12. As shown in FIG. 3, the drift member 13 includes two rectangular plate members 13a orthogonal to each other along a center line parallel to the respective long edge portions 13b, and centering on the intersection line 13c. The intersecting portion of the short edge portions 13d is rotated by 90 degrees in opposite directions, and the two plate members 13a are deformed so as to be twisted. Thereby, the two plate | board materials 13a which comprise the drift member 13 each form the helical surface centering on the intersection line 13c.

  If the drift member 13 having the shape shown in FIG. 3 is disposed in the base end portion 12c in a state in which the intersecting line 13c coincides with the axial center 12g (see FIG. 2) of the cylindrical body 12, as shown in FIG. In addition, the warm air sent from the warm air generating means 11 toward the cylindrical body 12 flows along the plate member 13a constituting the drift member 13 so that the direction of air flow is changed spirally, and the expansion / contraction part 12b. In order to flow in, the warm air swirl | vortex flow R is formed in the expansion-contraction part 12b. Thereby, since the warm air introduced into the cylindrical body 12 flows evenly in the expansion / contraction part 12b and uneven distribution and drift of the warm air in the expansion / contraction part 12b can be eliminated, the expansion / contraction part of the cylindrical body 12 12b The warm air is uniformly discharged from almost the entire surface, and the heating function can be enhanced.

  As shown in FIG. 4, the heater 10 can be used by extending the stretchable portion 12 b of the cylindrical body 12 linearly, but the usage is not limited, for example, as shown in FIG. 5, It is also possible to use the flexible stretchable part 12b in a state of being bent in a “<” shape or an “L” shape. In addition, as shown in FIG. 6, if the expansion / contraction part 12 b is bent in a “U shape” so as to surround the resident M, the area around the resident M can be intensively heated. Therefore, significant energy saving can be realized as compared with the case where the entire room is heated. Thus, since the expansion-contraction part 12b can be extended to the length suitable for the condition of the place to use, or can be changed, it is excellent in convenience.

  Furthermore, in the heater 10, as shown in FIG.1 (b), the expansion-contraction part 12b of the cylindrical body 12 can be shrunk along the axial direction, and, thereby, the size of an axial direction Can be reduced. For this reason, it is convenient without being bulky when the heater 10 is not used, or when the heater 10 is carried or stored. In addition, if the space which can accommodate the cylindrical body 12 which contracted the expansion-contraction part 12b is provided in a part of warm air generation means 11, by storing the said cylindrical body 12 in the warm air generation means 11, a season The storage space for the off heater 10 can be greatly reduced.

  As shown in FIG. 7, the heater 20 is used in a state where the spacer 21 s on the air suction port 21 a side of the hot air generating means 21 is brought into contact with the floor surface F and the cylindrical body 22 is erected in the vertical direction. be able to. At this time, the air suction port 21a is located away from the floor surface F by a distance corresponding to the height of the spacer 21s, so that there is no hindrance to air suction.

  As shown in FIG. 7, after setting the heater 20 in an upright state on the floor surface F, the grip 12e of the tip 12d of the stretchable part 22b is grasped by hand and moved up and down along the axis 12g. The length of 22b and the attitude | position holding member 23 can be changed. Since the posture holding member 23 is provided in the expansion / contraction part 22b, even if the hand is released from the grip 12e after adjusting the length of the expansion / contraction part 22b, it does not shrink or curve by its own weight. Standing posture is maintained. When the heater 20 is operated in this state, the warm air can be discharged over the entire 360 ° range centering on the cylindrical body 22, so that the heating effect of the entire room is greatly improved.
