Description

  The present invention relates to a wall-mounted heater in which a heater and a blower mechanism are housed in a case fixed to a wall.

  There is known a wall-mounted heater in which a heater and a blower mechanism are housed in a case fixed to a wall. As a conventional technique related to such a wall-mounted heater, there is a technique disclosed in Patent Document 1.

  Please refer to FIG. FIG. 7 is a diagram showing FIG. 16 of Patent Document 1 again. The reference numerals were reassigned as appropriate. As shown in Patent Document 1, a wall-mounted heater 110 includes a case 112 in which a heater 112 and a blower mechanism 113 that can blow air to the heater 112 are housed. The case 120 is fixed to the wall.

  When the air blowing mechanism 113 is operated, air is taken into the case 120 from the openings 124 a and 124 a formed on both side surfaces of the case 120. The taken-in air passes through the vicinity of the heater 112 and is warmed, and is sent out from the front of the case 120.

  According to the wall-mounted heater 110 that takes in air from the openings 124a and 124a on the side surfaces of the case 120, the case 120 can be fixed in the vicinity of the ceiling surface of the room. For example, in the case of a wall-mounted heater that takes in air from the top surface, it is necessary to keep a predetermined distance from the ceiling surface in order to ensure a desired flow rate. For this reason, the freedom degree of the arrangement | positioning place of a wall-mounted heater is reduced. According to the wall-mounted heater 110, since the openings 124a and 124a are formed on both side surfaces, air can be taken from one opening 124a even in the vicinity of the side wall. For this reason, the freedom degree of arrangement | positioning is high.

  Furthermore, even when the heater 112 is abnormally heated, air is taken in from the side surface, so that it is less susceptible to heat than when the opening is on the upper surface. Furthermore, the wall-mounted heater 110 is often arranged overhead, but since the opening 124a is located on the side surface, the opening 124a can be easily cleaned by the cleaner.

  By the way, generally, in order to suppress dust and dust from entering the inside of the case 120, a filter is put on the openings 124a and 124a. Such a filter is cleaned or replaced every predetermined period. It is preferable if such maintenance work can be easily performed.

For example, the filter part 32 is integrally provided in the frame 31 by insert molding.

  Please refer to FIG. An upper end portion of the frame body 31 is an inclined portion 31 a that extends obliquely toward the side surface portion 24. Further, the frame body 31 is formed with an extending portion 31b extending from the lower end of the inclined portion 31a to the lower side of the rail 25. A substantially L-shaped slider 33 that is locked to the rail 25 and is slidable on the rail 25 is integrally formed at the tip of the inclined portion 31a.

  By having the inclined portion 31a, the frame body 31 has an increased strength and is inclined toward the side surface portion 24. Therefore, the slider 33 can be reduced in size.

  The slider 33 includes a slider horizontal portion 33a extending substantially horizontally from the upper end of the inclined portion 31a toward the side surface portion, and a slider vertical wall portion 33b extending downward from the tip of the slider horizontal portion 33a. The lower end of the slider vertical wall portion 33 b is in contact with the upper surface of the rail horizontal wall portion 25 a of the rail 25. Thereby, the filter 30 is supported by the side surface portion 24.

  Please refer to FIG. The slider 33 is formed at both front and rear ends of the upper end portion of the frame body 31. In the vicinity of the portion of the inclined portion 31a where the rail 25 is formed, filter hole portions 33c and 33c, which are substantially rectangular holes, are formed, respectively.

  Please refer to FIG. At the lower end of the frame 31, a convex portion 34 that is fitted into the positioning concave portion 21 a of the back surface portion 21 is integrally formed. The convex portion 34 has a cylindrical shape, and the tip is formed in a tapered shape.

The claw portion 35 is inserted and locked in a locking hole 21 b provided in the back surface portion 21. In particular, as shown in FIG. 2, the locking hole 21b is formed below the opening 24a. That is, the claw portion 35 that is locked in the locking hole 21b is positioned below the opening 24a.

  Please refer to FIG. 5 and FIG. An abutting portion 31 d that can abut on the surface of the back surface portion 21 is formed at the end of the frame body 31 on the back surface portion 21 side. The claw portion 35 protrudes from the base end of the contact portion 31d toward the wall W (see FIG. 2) toward the wall W (see FIG. 2), and the claw portion main body 35a projects toward the edge of the locking hole 21b. Projecting portion 35b. The claw body 35a is formed in a thin shape toward the wall W. The edge of the locking hole 21b is sandwiched between the contact part 31b and the protrusion part 35b.

  Please refer to FIG. An example of a method for attaching the filter 30 to the side surface 24 will be described. First, the slider 33 is locked to the rail 25. Next, the filter 30 is moved toward the back surface portion 21 while sliding on the rail 25.

  Please refer to FIG. Even after the protrusion 35b (see FIG. 6) contacts the edge of the locking hole 21b, the filter 30 is pushed toward the back surface 21. Then, the projection 35b is pushed by the edge of the locking hole 21b, and the claw 35 is bent. When the filter 30 is further pushed in this state, the projection 35b gets over the edge of the locking hole 21b, and the bending of the claw 35 is restored. At this time, the convex portion 34 (see FIG. 5) is fitted into the positioning concave portion 21a, and the lower end of the filter 30 is prevented from rising.

  Since the filter portion 32 overlaps the entire opening 24a, dust and dust can be prevented from entering while air is taken into the case 20. By using for a predetermined period, a lot of dust and dirt adhere to the filter part 32. In order to efficiently take air into the case 20, it is necessary to remove the filter 30 and replace it with a new filter 30 or clean the filter portion 32.

  When removing the filter 30, the claw part 35 bends by pulling the filter 30 toward the indoor side. Since the thickness of the nail | claw part main body 35a and the projection part 35b is thinner than the width | variety of the locking hole 21b, the filter 30 can be extracted.

  The present invention described above has the following effects.

  Please refer to FIG. 2 and FIG. The side surface 24 has a rail 25 that supports the filter 30 so as to be slidable and extends substantially horizontally above the opening 24 a, and the filter 30 has a slider 33 that can slide on the rail 25. That is, the filter 30 is supported so as to be slidable in the substantially horizontal direction along the side surface portion 24. The filter 30 can be attached to the case 20 so as to slide toward the wall W. Even when the wall-mounted heater 10 is attached in the vicinity of the ceiling or the side wall, the required work space can be reduced, so that the filter 30 can be easily attached to and detached from the case 20. The wall-mounted heater 10 having excellent maintainability can be provided.

  In particular, the wall-mounted heater 10 is often placed overhead. Even in the case of being arranged at such a high place, the filter 30 can be detached and attached by sliding in the horizontal direction, so that the attachment / detachment work of the filter 30 can be easily performed.

  In addition, when removing the filter by sliding it upward, the wall-mounted heater needs to be separated from the ceiling by the amount necessary for the removal work. On the other hand, when removing the filter by sliding it down, it is necessary to separate the wall-mounted heater from the furniture or the like placed under the wall-mounted heater by the amount necessary for the removal work. That is, when sliding up and down, a great restriction is imposed on the degree of freedom of arrangement of the wall-mounted heater. In this regard, by adopting a configuration in which the filter 30 is slid horizontally along the side surface portion 24 of the case 20, a high degree of freedom in arranging the wall-mounted heater 10 can be ensured.

  Reference is also made to FIG. The rail 25 is provided above the opening 24a. Thereby, it is possible to prevent dust and dirt from entering the inside of the case 20 from the gap between the case 20 and the filter 30.

  Please refer to FIG. 2 and FIG. The filter 30 is provided with a convex portion 34 which is formed in a convex shape and fitted into the positioning concave portion 21a. Thereby, the filter 30 can be reliably put on the opening 24a. Dust and dust can be prevented from entering the case 20.

  The filter 30 has a claw portion 35 that protrudes toward the wall W below the opening 24 a, and the claw portion 35 is locked in a locking hole 21 b formed in the back surface portion 21. When the filter 30 is slid, the filter 30 is slid to a position where the claw portion 35 is locked in the locking hole 21b. The filter 30 can be attached to the case 20 easily and accurately.

  In addition, the filter 30 can be prevented from being lifted by being locked in the locking hole 21b. Since the nail | claw part 35 is located below the opening part 24a, it can cover the filter 30 on the opening part 24a reliably with the slider arrange | positioned above the opening part 24a. Dust and dust can be prevented from entering the case 20.

  Further, the convex portion 34 is provided at the lowermost portion of the filter 30. In many cases, the wall-mounted heater 10 is fixed overhead. The operability can be improved by providing a portion requiring fine adjustment for positioning at a location closer to the operator. The same effect can be obtained when a positioning recess is formed at the lowermost part of the filter 30.

  Further, the outer edge of the frame 31 of the filter 30 has the same shape as the outer edge of the side surface portion 24. In many cases, the wall-mounted heater 10 is fixed overhead. Since the frame 31 is large, by having the lower end of the frame 31, the operator can perform the attachment work of the filter 30 at a closer position, and the attachment / detachment work becomes easy.

  Although the wall-mounted heater according to the present invention has been described by taking the wall-mounted heater used in the dressing room as an example, the place where the wall-mounted heater is used is not limited to the dressing room.

  The present invention is not limited to the examples as long as the functions and effects of the present invention are exhibited.

  The wall-mounted heater of the present invention is suitable for warming a dressing room.
