Description

  The present invention relates to an air conditioner such as a bathroom heater provided with a mist generating device.

 For example, when a bathroom heater is attached to the side wall of a bathroom, a means for fixing a metal mounting plate to the side wall of the bathroom in advance and supporting the bathroom heater on the mounting plate is often used. As a specific means for supporting the bathroom heater on the mounting plate, an engaging part is formed on the upper part on the back side of the bathroom heater, and this engaging part is formed on the upper part of the mounting plate. A means for hooking the bathroom heater to the mounting plate by engaging with the protrusion is often employed (see, for example, Patent Document 1). However, since this alone makes the installation of the bathroom heater unstable, the lower part of the bathroom heater is also screwed to the mounting plate.

  On the other hand, some bathroom heaters include a mist generating device in the lower part (see, for example, Patent Document 2). As the mist generating device, various configurations are conceivable. However, if the mist ejection direction is fixed, it is not convenient for the user. For this reason, it is desired that the mist generating device be rotated around a predetermined central axis by, for example, a motor and change the mist ejection direction by this rotating action.

  However, when the rotatable mist generating device is attached to the lower part of the bathroom heater, when the bathroom heater is attached to the side wall of the bathroom using an attachment plate, the following will be described. , Cause a defect.

  That is, when the lower part of the bathroom heater is screwed to the lower part of the mounting plate fixed to the side wall of the bathroom, the mist generating device attached to the lower part of the bathroom heater interferes with the screwing work. . As a means for solving this problem, it is conceivable to provide a work space in the front area of the screwing place by separating the lower part of the bathroom heater and the upper part of the mist generating device greatly. Adopting this makes the appearance of the bathroom heater considerably worse. Moreover, the enlargement of the whole apparatus will also be invited.

  The present invention has been conceived under the circumstances as described above, and is a mist that can be accurately attached to a desired wall and can have a good appearance. The problem is to provide an air conditioner equipped with a generator.

  In order to solve the above problems, the present invention takes the following technical means.

  An air conditioner equipped with a mist generating device provided by the present invention has a mist generating device that can be rotated around a predetermined central axis attached to the lower portion, and the upper portion engaged with a mounting plate fixed to a desired wall portion. An air conditioner equipped with a mist generating device that is supported by the mounting plate, and a part of the mounting plate at a position above the mist generating device in a lower part of the air conditioner. A contact portion that contacts the mounting plate is provided with a screw body insertion hole through which a screw body for connecting to the mounting plate can be inserted obliquely upward. The mist generating device can be rotated in a posture in which the upper surface is inclined in a forward and downward direction. When the mist generating device is in the posture, the mist generating device is located above the mist generating device with respect to the screw body insertion hole. Insert the screw body diagonally from below It is characterized in that the space space to enable its tightening work is configured to be formed.

  According to such a configuration, the screw body can be inserted into the screw body insertion hole from the front side of the space and tightened. By this operation, the lower part of the air conditioner is appropriately connected to the mounting plate, and the air conditioner is attached in a stable state. Here, the space space is formed when the upper surface of the mist generating device is rotated to a posture inclined in a front-down manner, and the screw body is inserted from the diagonally lower front to the screw body insertion hole. It is possible. For this reason, according to the present invention, it is possible to make a part of the air conditioner exist in the front area of the screw body insertion hole, for example, by providing a louver for blowing air. It is not necessary to form an open and unsightly space. As a result, the overall appearance is improved, and the problem that the whole is unnecessarily enlarged is appropriately avoided.

  In a preferred embodiment of the present invention, the mist generating device is rotatable about the predetermined central axis by driving a motor, and when the operation of the mist generating device is turned off, the mist generating device has a predetermined angular attitude. And when the mist generating device returns to the predetermined angular posture, the mist generating device is configured to block an area obliquely below the front of the screw body insertion hole. Yes.

  According to such a configuration, when the operation of the mist generator is turned off, the screw body insertion hole can be concealed by the mist generator. When the operation of the mist generating device where mist is not ejected is turned off, the screw body insertion hole can be visually inferior if it is visible from the outside. However, according to the above configuration, such a problem is appropriately avoided. The

  In a preferred embodiment of the present invention, the mist generating device includes a cover case having first and second surfaces that intersect and cross each other, and the first of the first and second surfaces is the first. An opening for mist ejection is formed only on the first surface, and when the operation of the mist generating device is turned off, the first surface faces downward and the second surface faces the front. It is configured.

  According to such a configuration, when the operation of the mist generating apparatus is turned off, the first surface of the cover case faces downward, making it difficult to see the mist ejection port, and the second surface where the mist ejection port is not formed. Therefore, the appearance of the mist generating device can be made clean and good-looking.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  1-11 has shown an example of the bathroom heater provided with the mist generator to which this invention was applied, and the structure relevant to this. As clearly shown in FIG. 1, in the present embodiment, a mist generating device MG is connected to the lower part of the bathroom heater A via brackets 2A and 2B.

  As shown in FIG. 2, the bathroom heater A is a wall-hanging type that is used by being attached to the wall 90 of the bathroom, and a heat exchanger 51 and an intake / exhaust fan 52 are provided in the case 50. It has a housed configuration. The upper wall portion 50c of the case 50 is an intake grille having a plurality of intake ports 50d. After the fan 52 is driven, the bathroom air flows into the case 50 from the intake ports 50d and is heated by the heat exchanger 51. The air is sent from the air outlet 53a of the louver 53 provided in the lower front portion of the case 50 toward the bathroom. The heat exchanger 51 is divided into, for example, a plurality of blocks 51a to 51c surrounding the fan 52. These are both configured using finned tubes, and hot water is supplied into the tubes. Can be heated by air.

  The case 50 is attached to the bathroom wall 90 using the attachment plate 8. Specifically, as shown in FIG. 5, the mounting plate 8 is a metal plate having a pair of engaging protrusions 80 at the upper portion and a receiving plate portion 81 at the lower portion. It is fixed to the part 90. An engagement portion 50a having a lower opening-shaped recess 50a ′ that can be engaged with the engagement protrusion 80 of the attachment plate 8 is formed on the back surface of the case 50, and the case 50 is attached to the attachment plate by these engagements. 8 is hooked. A pair of abutting portions 50 b that abut against the receiving plate portion 81 of the mounting plate 8 are formed in the lower portion of the back surface portion of the case 50. The contact portion 50b and the receiving plate portion 81 are connected to each other by using screw body insertion holes 50b 'and 81a and a screw body 95 (see FIG. 2) inserted therethrough. However, the receiving plate portion 81 and the contact portion 50b are both inclined, and the screw body 95 is inserted into the receiving plate portion 81 from the contact portion 50b side obliquely upward. Details of the tightening operation of the screw body 95 will be described later. As shown in FIG. 2, the contact portion 50 b is located behind the attachment location of the louver 53.

  As shown well in FIGS. 6 and 7, the mist generator MG is a unit obtained by assembling the cover case 1 with the mist ejection mechanism B and the two motors M. The cover case 1 is made of, for example, a synthetic resin such as ABS resin and has a form extending in a certain direction. The back surface of the cover case 1 (the front side in FIGS. 6 and 7) is open, and the mist ejection mechanism B and the motor M are accommodated in the cover case 1 from the opening. Brackets 2A and 2B are connected to cover case 1, and these brackets 2A and 2B are metal fittings made of stainless steel, for example. These include a horizontal plate portion 20 that is set substantially horizontally, and a hanging portion 21 that extends downward from the horizontal plate portion 20.

  The mist ejection mechanism B has a function of guiding hot water (warm water or non-heated water) supplied to the receiving port 30a of the connector 30 to the plurality of mist nozzles 31 and ejecting mist. The mist ejection mechanism B includes a rotatable joint 33 and an opening / closing valve Va connected to a connector 30 via a pipe portion 32, and a plurality of mist nozzles 31 connected to the opening / closing valve Va and the rotatable joint 33. The piping part 34 is comprised. The plurality of pipe portions 34 are provided with a plurality of bracket portions 35 into which the screw bodies 91 are inserted, and these portions are screwed to fix the mist ejection mechanism B to the cover case 1. It has been. However, the connection tool 30 is fixed to the bracket 2 </ b> A using a screw body 92. Since the rotatable joint 33 is connected to the piping part 32 connected to the connecting tool 30, the parts other than the connecting tool 30 and the piping part 32 in the mist ejection mechanism B are connected to the rotatable joint 33. It is possible to rotate together with the cover case 1 around the central axis C1 serving as the rotation center.

  The plurality of mist nozzles 31 are arranged at appropriate intervals in the longitudinal direction of the cover case 1, and as shown in FIG. 1, the front surface 10a of the cover case 1 (corresponding to an example of the first surface in the present invention). The mist can be ejected from the plurality of mist ejection openings 11 provided in the forward direction. The mist ejection mechanism B has a piping structure as schematically shown in FIG. 8, and hot water supplied to the receiving port 30 a is guided to all of the mist nozzles 31 when the on-off valve Va is open. Is ejected. On the other hand, when the open / close valve Va is in the closed state, water supply to the mist nozzle 31 (31a) is blocked and mist is ejected only from the mist nozzle 31 (31b). Thus, the mist ejection amount can be changed. As the mist nozzles 31a and 31b, nozzles having different mist ejection amounts and ejected mist particle sizes can be used.

  As shown in FIGS. 6 and 7, the two motors M are accommodated in both ends in the longitudinal direction of the cover case 1 and are fixed to the cover case 1 using screw bodies 93. The center coincides with the central axis C1. The two motors M are configured such that the drive shaft 70 is connected to the brackets 2A and 2B. By this connection, the two motors M are supported by the brackets 2A and 2B, and the cover case 1 and the mist ejection mechanism B are also indirectly supported by the brackets 2A and 2B. As described later, the above-described connection is configured such that relative rotation between the brackets 2A and 2B and the drive shaft 70 is prevented. Thus, when the motor M is driven, the main body 71 of the motor M rotates with the cover case 1.

  As specific connecting means between the drive shaft 70 of the motor M and the bracket 2A, for example, means as shown in FIGS. 9A and 9B are used. That is, a coupling cap 73 is attached to the drive shaft 70 so as not to be relatively rotatable, and the cap 73 is inserted into the hole 22 of the hanging portion 21 of the bracket 2A, whereby the drive shaft 70 and the bracket 2A are inserted. Connection with is planned. However, the cap 73 has a flange 73a, a notch 73b as a narrow part, and a non-notch 73c. On the other hand, the hole 22 has a circular upper part 22a and a lower part 22b having a rectangular shape. When connecting the drive shaft 70 to the bracket 2 </ b> A, first, the flange 73 a of the cap 73 attached to the drive shaft 70 is inserted into the upper portion 22 a of the hole 22 as indicated by an arrow N <b> 1 in FIG. Next, as shown by the arrow N2, the cap 73 is lowered to allow the cutout portion 73b to enter the lower portion 22b. Then, the cap 73 and the drive shaft 70 are connected to the bracket 2A so as not to rotate relative to the bracket 2A, and the motor M is supported by the bracket 2A by the fitting action of the notch 73b and the lower portion 22b. Since the flange 73a and the non-cutout portion 73c of the cap 73 sandwich the hanging portion 21 in the thickness direction, the displacement of the cap 73 in the thickness direction of the hanging portion 21 is also appropriately restricted. The connection structure of the drive shaft 70 of the motor M to the other bracket 2B is the same as described above.

  The mist generator MG is supported by hooking brackets 2A and 2B to the lower part of the case 50 of the bathroom heater A. More specifically, as shown in FIG. 11, support portions 54 that form a pair of concave grooves 54 a are provided at the lower portions of both ends in the width direction of the case 50. The pair of concave grooves 54 are open at the rear (front side in FIG. 11) and the inner side. Each horizontal plate part 20 of bracket 2A, 2B is inserted from the opening part of the rear part with respect to each groove 54a. As a result, as shown in FIG. The brackets 2 </ b> A and 2 </ b> B are fixed to the support portion 54 using the screw body 96, and the attachment thereof is ensured. By such setting of the brackets 2 </ b> A and 2 </ b> B, the mist generator MG is accurately attached below the case 50. A piping 59 for hot water supply is connected to the receiving port 30a.

  Next, the operation of the bathroom heater A provided with the mist generator MG will be described.

  First, in order to attach the bathroom heater A to the bathroom wall 90, the bathroom heater A is engaged by engaging the engaging portion 50 a of the case 50 with the engaging protrusion 80 of the attachment plate 8 as shown in FIG. 3. The machine A is hooked on the mounting plate 8. Next, the contact portion 50 b is brought into contact with the receiving plate portion 81 of the mounting plate 8 and screwed. At the time of this screwing, the mist generating device MG is appropriately rotated around the central axis C1 so that the upper surface 10b of the cover case 1 (corresponding to an example of the second surface in the present invention) is in a posture that is lowered downward. As a result, a space S is formed above the mist generator MG. The space S is a space that extends obliquely downward from the front portion 50b and has an open front portion. Therefore, the screw body 95 is inserted into the screw body insertion holes 50b ′ and 81a by causing the screw body 95 and the driver tool supporting the screw body 95 to enter obliquely upward from the front (left side in FIG. 3) of the space S. It can be inserted and the tightening work can be performed appropriately. By this tightening, the lower part of the bathroom heater A is also stabilized, and an accurate attachment is achieved.

  If the above-described means is adopted so that the contact portion 50b and the receiving plate portion 81 can be screwed, the front area of the front portion for the screwing operation is large in the front area of the contact portion 50b. It is not necessary to form a space. Therefore, the appearance of the bathroom heater A can be improved. A louver 53 or the like can be provided in front of the contact portion 50b. In addition, the mist generating device MG can be made considerably closer to the lower part of the bathroom heater A, and the size of the entire vertical direction can be suppressed from increasing.

  When the bathroom heater A is attached to the wall 90 and used, there are cases where it is desired to remove the bathroom heater A from the wall 90 for maintenance or other reasons. Even in this case, as shown in FIG. 3, the mist generating device MG is set in a predetermined posture and the space space S is formed, so that the screwing release operation of the contact portion 50b can be accurately performed. It is. When attaching and detaching the screw body 95, the operator may drop the screw body 95 below the contact portion 50b. In this case, when the screw body 95 falls into the cover case 1 of the mist generating device MG, the removal is troublesome. As a means for preventing this, a guide 59 (indicated by a phantom line in FIG. 3) for preventing the screw body 95 from falling into the cover case 1 or a cover member (not shown) in place thereof is put in place. It can also be set as the provided structure.

  The operation of the mist generating device MG is controlled by control means (not shown). When the operation of the mist generating device MG is turned on, hot water is supplied to the receiving port 30a, and a plurality of mist nozzles are operated. Mist is ejected from 31. In this case, when the two motors M are driven, the cover case 1 rotates around the central axis C1, and the mist nozzle 31 rotates accordingly. For this reason, it becomes possible to change the mist ejection direction from the mist nozzle 31 up and down to properly eject the mist to a location desired by the user. It is also possible to control to swing the cover case 1 by rotating the motor M forward and backward at a constant angle. Further, as described with reference to FIG. 8, the mist ejection amount desired by the user is switched by switching between a state in which mist is ejected from all of the mist nozzles 31 a and 31 b and a state in which mist is ejected from only the mist nozzle 31 b. It can also be obtained.

  When the operation is turned off, the mist generator MG is controlled so as to be in the posture shown in FIG. When the mist generating device MG is in such a posture, a region obliquely below the front of the contact portion 50b is closed by the cover case 1. Thereby, it is possible to prevent the tightening portion of the screw body 95 from being seen from the front side of the bathroom heater A. When the operation of the mist generating device MG is turned off, since no mist is ejected, it is possible to observe each part of the device well. However, in this embodiment, in such a case, the tightening portion of the screw body 95 is Since it cannot be seen, deterioration of appearance can be prevented. Further, the posture of the mist generator MG shown in FIG. 4 is a posture in which the front surface 10a of the cover case 1 faces downward and the surface 10b (a surface corresponding to the upper surface of FIG. 3) faces the front. If the cover case 1 is set in such a posture, the plurality of mist ejection openings 11 are difficult to see, and the clean surface 10b on which the mist ejection openings 11 are not formed faces the front, The appearance of the mist generator MG can be improved.

  The mist generating device MG is attached to the lower part of the bathroom heater A via the brackets 2A and 2B, and can be removed from the bathroom heater A by removing the brackets 2A and 2B from the recessed grooves 54a of the support portion 54. Is possible. Therefore, when the mist generating device MG fails, it is possible to remove only the mist generating device MG and repair it separately from the bathroom heater A. Since the mist generating device MG has a configuration in which the mist ejection mechanism B and the motor M are mounted on the cover case 1 and these are unitized, the mist generating device MG is handled when being attached to and detached from the lower part of the bathroom heater A. Excellent in properties.

  The air conditioner referred to in the present invention is not limited to a bathroom heater, but can also be applied to those installed and used in places other than the bathroom. The mist generating device may be any device that has a function of ejecting mist and can rotate around a predetermined central axis. The rotation of the mist generating device may be performed by, for example, an operator, a user, or the like manually pushing the mist generator without being driven by a motor. Further, the mist generator may not be provided in a state separated from the case of the air conditioner. For example, the whole or part of the mist generating device may be surrounded by the case of the air conditioner, and the mist generating device may be integrated in the case of the air conditioner or a configuration close thereto.
