Description

  The present invention relates to a structure for attaching an accessory device to an air conditioner that is applied to attach a desired accessory device such as a mist generator to a bathroom heater or other air conditioner.

  When installing a mist generating apparatus in a bathroom, this mist generating apparatus is often attached to the lower part of a bathroom heater (for example, refer to Patent Document 1). By adopting such means, the bathroom heater and the mist generator can be integrated, and the overall appearance and the like can be improved. In addition, it is possible to obtain an action of causing the mist generated by the mist generator to advance to a desired area in the bathroom using the air blown from the bathroom heater.

  However, in the prior art, there are points to be improved as described below.

  That is, the mist generating device may cause a failure or the like for an individual reason from the bathroom heater. For this reason, it is desired that the mist generating device be easily removed from the bathroom heater and repaired or inspected separately from the bathroom heater. On the other hand, when the mist generating device is attached to the bathroom heater, it is not sufficient to simply remove the mist generating device from the bathroom heater, and it is also desired to increase the mounting reliability. For example, if an appropriate bracket is connected to the mist generating device and this bracket is screwed to the bathroom heater, the removal work and the like can be facilitated. In the unlikely event that the stop portion is loosened, there is a high possibility that the attached state of the mist generating device is released. Therefore, since only such attachment means gives anxiety to the user, it is also desired to eliminate such a situation. On the other hand, the actual situation is that no means for sufficiently satisfying the above-described demand has been provided. Therefore, there was room for improvement in this regard. In addition, this point is the same not only when attaching a mist generating apparatus to a bathroom heater but when attaching other attachments different from a mist generating apparatus to air conditioners other than a bathroom heater.

  The present invention has been conceived under the circumstances as described above, and it is easy to attach / detach the accessory device to / from the air conditioner, and the reliability of the attachment in a state where the accessory device is attached to the air conditioner. It is an object of the present invention to provide a structure for attaching an accessory device to an air conditioner that can enhance the performance.

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

  An attachment structure of an accessory device to an air conditioner provided by the present invention includes an air conditioner and an accessory device attached to a lower portion of the air conditioner via one or more brackets. An attachment structure for an attachment device, wherein the bracket includes a pair of horizontal plate portions, and a pair of hanging portions depending downwardly from the horizontal plate portions and connected to the attachment device. The air conditioner is provided with a pair of concave grooves having a depth in a substantially horizontal direction and having at least one side opened at an interval in the horizontal direction, and the bracket includes the pair of horizontal plate portions. The air conditioner is hooked by being inserted into the pair of concave grooves.

  According to such a configuration, the attachment device is attached to the lower portion of the air conditioner via the bracket, and the bracket is connected to the air conditioner by providing the pair of horizontal plate portions of the bracket to the air conditioner. This can be done by inserting into a pair of concave grooves. Further, if the horizontal plate portion of the bracket is removed from the concave groove of the air conditioner, the accessory device can be removed from the air conditioner. For this reason, it is easy to attach / detach the accessory device to / from the air conditioner, and it is convenient to separate the accessory device from the air conditioner for individual maintenance / inspection. On the other hand, when the accessory device is attached to the air conditioner, the pair of horizontal plate portions of the bracket are inserted into the pair of substantially horizontal concave grooves, and the bracket is stably latched to the air conditioner. Therefore, unlike the case where the bracket is simply screwed to the air conditioner, for example, it is possible to prevent the connection state from being easily released by loosening of the screws. Therefore, the effect of improving the reliability with respect to the attachment of the accessory device can also be obtained.

  In a preferred embodiment of the present invention, the air conditioner is provided with a screwing portion for screwing a pair of horizontal plate portions of the bracket to the air conditioner. The arrangement is such that the area directly below the screwing portion is avoided, and the screwing operation and the releasing operation of the screwing portion can be performed from below the air conditioner.

  According to such a configuration, by screwing the pair of horizontal plate portions of the bracket to the air conditioner, the mounting reliability of the bracket can be further improved, as well as the screwing operation and the release operation thereof. Since it can be performed from below the air conditioner, workability at the site where the air conditioner is installed is also improved.

  In a preferred embodiment of the present invention, the pair of concave grooves has a form in which a front portion is closed and a rear portion is opened, and the pair of horizontal plate portions are formed in the pair of concave grooves. On the other hand, when the air conditioner is inserted into a desired wall portion, the pair of horizontal plate portions escapes behind the pair of concave grooves when the air conditioner is attached to a desired wall portion. The bracket is configured to be blocked by contacting the wall portion.

  According to such a configuration, it is possible to prevent the horizontal plate portion of the bracket from escaping from the groove of the air conditioner by using the wall portion to which the air conditioner is attached, and the bracket is inadvertently removed from the air conditioner. It is possible to prevent it from coming off more thoroughly.

  In a preferred embodiment of the present invention, an engagement portion for hooking the air conditioner on an attachment plate fixed to the wall is formed on the upper portion of the air conditioner. A connecting means for connecting the lower part of the air conditioner to the mounting plate is provided in the lower part of the air conditioner. When the lower part of the air conditioner is connected to the mounting plate, the pair of The horizontal plate portion is prevented from escaping to the rear of the pair of concave grooves when the accessory device or the bracket is in contact with the wall portion, and when the connection is released, the air conditioner is mounted. While being hooked on a plate, the lower part of the air conditioner can be separated from the wall portion to ensure a space for allowing the pair of horizontal plate portions to escape from the pair of concave grooves. ing.

  According to such a configuration, with the air conditioner being hooked on the mounting plate, the work of removing each horizontal plate portion of the bracket from the concave groove of the air conditioner, and the horizontal plate portion escaped from the concave groove are recessed. The operation of reinserting into the groove can be performed, and the attachment / detachment operation of the accessory device is further facilitated.

  In a preferred embodiment of the present invention, the air conditioner is a bathroom heater, and the auxiliary device is a mist generating device that ejects the supplied liquid as mist. Of course, the air conditioner and the accessory device referred to in the present invention are not limited thereto.

  In a preferred embodiment of the present invention, a pipe connector for receiving the mist liquid of the mist generator is attached to the bracket.

  According to such a configuration, in addition to maintaining the position of the pipe connector for receiving the mist liquid at a fixed position, the position is the boundary portion of the attachment point between the bathroom heater and the mist generating device or the position thereof. Since it becomes a vicinity part, the attachment or detachment operation | work of piping with respect to this part is also facilitated.

  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.

  FIGS. 1-14 has shown an example of the attachment structure of the attachment apparatus to the air conditioner based on this invention, 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 side wall 90 of the bathroom, and a heat exchanger 51 and an intake / exhaust fan 52 are accommodated in the case 50. It has the structure which was made. The upper wall portion 50c of the case 50 is an intake grille having a plurality of intake ports 50d. When the fan 52 is driven, bathroom air flows into the case 50 from the intake ports 50d and is heated by the heat exchanger 51, and thereafter The air is blown toward the bathroom from the air outlet 53a of the louver 53 provided in the lower front portion of the case 50. 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 side wall 90 of the bathroom using the attachment plate 8. More specifically, as shown in FIG. 3, 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, and using a screw body 94. It is fixed to the side wall 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 bracket piece 50b that is in contact with the receiving plate 81 of the mounting plate 8 is formed in the lower portion of the back surface of the case 50. These portions include holes 81a and 50b ′ and a screw body 95 (see FIG. 2).

  As shown well in FIGS. 4 and 5, the mist generator MG is a unit formed by assembling the mist ejection mechanism B and two motors M to the cover case 1. A pair of brackets 2A and 2B are also attached to the cover case 1.

  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. 4 and 5) is open, and the mist ejection mechanism B and the motor M are accommodated in the cover case 1 from the opening.

  The brackets 2A and 2B are metal fittings made of stainless steel, for example. Each of these brackets 2A, 2B has 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 toward the front of the cover case 1. I have. The mist ejecting mechanism B connects the rotary joint 33, the open / close valve Va, and the open / close valve Va and the rotary joint 33, which are connected to the connector 30 via the pipe 32, to the plurality of mist nozzles 31. A plurality of piping parts 34 are provided. The mist ejection mechanism B is fixed to the cover case 1 by the bracket portions 35 provided in the plurality of piping portions 34 being screwed to a plurality of locations of the cover case 1 using the screw bodies 91. It is installed. Although not shown in the drawings, preferably, the rotatable joint 33 and the opening / closing valve Va are also screwed to the cover case 1. The connection tool 30 is fixed to the horizontal plate portion 20 of 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 an appropriate interval in the longitudinal direction of the cover case 1. As shown in FIG. 6, the plurality of nozzle openings 11 provided in the front portion 10 a of the cover case 1. The mist can be ejected from the front toward the front. For example, two types of mist nozzles 31 are used. More specifically, the mist nozzle 31a near the both ends in the width direction of the cover case 1 has a larger mist ejection amount than the mist nozzle 31b near the center in the width direction. The particle diameter of the mist ejected is smaller in the mist nozzle 31b than in the mist nozzle 31a.

  The mist ejection mechanism B has a piping structure as schematically shown in FIG. 7, and when the open / close valve Va is open, the hot water supplied to the receiving port 30a is distributed to all the mist nozzles 31a and 31b. It is guided and gushes. On the other hand, when the open / close valve Va is in the closed state, water supply to the mist nozzle 31a is blocked and mist is ejected only from the mist nozzle 31b.

  As shown in FIGS. 8 (a) and 8 (b), the mist nozzle 31 is connected to a piping part 34, and hot water that has progressed from the piping part 34 to the inside can be ejected as a mist from the nozzle port 310 at the tip. It is. The principle of converting the hot water flowing into the mist nozzle 31 into a mist is the same as that of a conventional mist nozzle. For example, a high-speed swirling flow of hot water is generated in the mist nozzle 31 and this is led to a channel having a small inner diameter. This is a method of ejecting from the opening while restricting. The mist nozzle 31 is provided so as to be rotatable about the central axis C <b> 2 of the standing portion 34 a with respect to the standing portion 34 a of the pipe portion 34. This makes it possible to change the direction of the nozzle port 310 in the left-right direction (the longitudinal direction of the cover case 1).

  As means for stabilizing the orientation of the nozzle port 310, the cover case 1 is provided with the engaged portion 12 having a plurality of recesses integrally or separately, and the mist nozzle 31 has a protrusion 35a. An engagement member 35 is attached. When the mist nozzle 31 is rotated, the convex portion 35a of the engaging member 35 is engaged with any of the concave portions of the engaged portion 12, so that the mist nozzle 31 can be positioned so as not to rotate inadvertently. is there. As shown in FIG. 6, the nozzle opening 11 has a long hole shape extending in the longitudinal direction of the cover case 1, and the mist is placed in front of the cover case 1 regardless of whether the direction of the mist nozzle 31 is changed to the left or right. Appropriate ejection is possible. In order to change the direction of the mist nozzle 31, an operator or user or the like from the front side of the cover case 1 presses and rotates the tip of the mist nozzle 31 with a finger or an appropriate member. Good.

  As shown in FIGS. 4 and 5, 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 by 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. With 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 formed at the tip thereof, a notch 73b as a narrow portion adjacent to the flange 73a, and a non-notch 73c adjacent thereto. In contrast, the upper portion 22a and the lower portion 22b of the hole 22 are different in shape and size. For example, the upper portion 22a has a circular shape, whereas the lower portion 22b has a narrower rectangular shape. is there. As an operation procedure for connecting the drive shaft 70 to the bracket 2A, first, as indicated by an arrow N1 in FIG. 4A, the flange 73a of the cap 73 attached to the drive shaft 70 is inserted into the upper portion 22a of the hole portion 22. Let Next, as shown by the arrow N2, the cap 73 is lowered to allow the cutout portion 73b to enter the lower portion 22b. When such an operation is performed, 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. Is done. 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. Although a detailed description is omitted, 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 generating device MG is attached to the bathroom heater A with a structure as shown in FIGS. More specifically, as shown in FIG. 12, a support portion 54 having a concave groove 54 a is provided below the pair of side wall portions 50 c of the case 50. The concave groove 54 has a depth in a substantially horizontal direction, and has a form in which a rear portion (front side in FIG. 12) and an inner portion are opened, and a front portion and an outer portion are closed. The support portion 54 is also provided with a screw hole 54b. This portion corresponds to an example of the screwing portion referred to in the present invention (note that in FIGS. 11 and 12, the support portion 54 is shown to be located rearward from FIG. 11 and FIG. 12 to make it easier to see the left support portion 54).

  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 FIGS. 10 and 11, the brackets 2A and 2B are hooked on the support portion 54, and the mist generator MG is attached to the lower part of the bathroom heater A via the brackets 2A and 2B. ing. In this attached state, the rear portion of the cover case 1 of the mist generating device MG is disposed relatively close to the bathroom side wall 90 (the significance of this will be described later). The horizontal plate part 20 of the brackets 2 </ b> A and 2 </ b> B is fixed to the support part 54 using a screw body 96. The horizontal plate 20 protrudes outward in the width direction from the cover case 1 of the mist generator MG. As a result, as shown in FIG. 11, the cover case 1 of the mist generator MG is arranged so as to avoid the region directly below the support portion 54, and the screw body 96 is tightened in the region directly below the support portion 54. A space S for performing the above is secured. An appropriate pipe 59 is connected to the receiving port 30a of the mist generator MG behind the case 50 so that hot water can be supplied.

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

  First, in the attached state of the mist generating device MG, the brackets 2A and 2B are hooked to the support portion 54 of the bathroom heater A by the horizontal plate portion 20 being inserted into the substantially horizontal concave groove 54a. ing. For this reason, unlike this embodiment, compared with the case where bracket 2A, 2B is attached to bathroom heater A using only a suitable screw body, for example, attachment of bracket 2A, 2B is ensured. In other words, even if the screw body 96 is loosened and the screw body 96 is dropped, the brackets 2A and 2B are maintained in the state of being hooked on the case 50, so that the mist generator MG falls. Properly prevented. In addition, when the screw body 96 is dropped, if the brackets 2A and 2B are largely displaced rearward, the brackets 2A and 2B may be detached from the support portion 54. However, in the present embodiment, when the brackets 2 </ b> A and 2 </ b> B are largely displaced rearward, the rear portion of the cover case 1 comes into contact with the wall portion 90. Due to this abutting action, the brackets 2A and 2B are not greatly displaced rearward, and the horizontal plate portion 20 is also preferably prevented from coming off from the concave groove 54a. For this reason, an effect of thoroughly preventing the mist generator MG from dropping off can be obtained, and a great sense of security can be given to the user.

  Next, when the mist generator MG is maintained and inspected separately from the bathroom heater A, it can be handled as follows. That is, if the screw body 95 which connects the lower part of the bathroom heater A and the receiving plate part 80 of the mounting plate 8 is loosened and the connection of these parts is released, the lower part of the bathroom heater A is shown in FIG. Can be separated from the side wall 90 of the bathroom. For example, as shown in FIG. 14, the screw body 95 is loosened by rotating the mist generating device MG to secure a space where the driver can be inserted from above the mist generating device MG. It can be done in the state. As shown in FIG. 13, when the lower part of the bathroom heater A is moved away from the side wall 90, the mist generating device MG can be largely retracted toward the side wall 90. For this reason, it becomes possible to remove the horizontal plate part 20 of bracket 2A, 2B from the ditch | groove 54a, and to remove the mist generator MG from the bathroom heater A. When performing such an operation, the bathroom heater A can be hooked on the engaging projection 80 of the mounting plate 8, so the burden on the operator is small. Moreover, although it is necessary to loosen the screw body 96 which has fixed bracket 2A, 2B to the support part 54a beforehand, this operation | work is the space space S below the bathroom heater A (refer FIG. 11). Since it can be performed by using, it is still easy.

  After that, when the mist generator MG is attached to the bathroom heater A again, the bathroom heater A is inclined as shown in FIG. 13 and the horizontal plate portions 20 of the brackets 2A and 2B are made with respect to the groove 54a. The screw body 95, 96 may be tightened by inserting from the opening of the rear part. These operations can be easily performed as in the case where the mist generator MG is removed. In addition, when the mist generator MG is attached / detached, it is also necessary to attach / detach the hot / cold water supply pipe to / from the connector 30. On the other hand, the connector 30 is attached to the bracket 2A and is maintained at a fixed position, and the position thereof is a boundary portion of the attachment portion between the bathroom heater A and the mist generator MG or a portion in the vicinity thereof. Since it is close to the widthwise ends of the bathroom heater A and the mist generator MG, the hot water supply pipe can be easily attached to and detached from this portion. Thus, in the present embodiment, the mist generator MG can be easily attached and detached, which is preferable for performing maintenance and inspection separately from the bathroom heater A.

The mist generating device MG has a configuration in which the mist ejecting mechanism B and the motor M are mounted on the cover case 1, and since these are unitized, the handling becomes easier.
When the two motors M are driven, the cover case 1 rotates about the central axis C1 shown in FIG. 4. As a result, the mist nozzle 31 also rotates with the cover case 1, and from the mist nozzle 31. The mist ejection direction can be changed up and down. It is also possible to control to swing the cover case 1 by rotating the motor M forward and backward at a constant angle. In addition, as described with reference to FIGS. 6 and 8, the direction of the mist nozzle 31 can be changed in the horizontal direction. For this reason, it becomes possible to eject mist more appropriately to the place which a user requests. Further, as described with reference to FIG. 7, 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 mist ejection direction is changed up and down, since there is no relative movement between the mist nozzle 31 and the cover case 1, the nozzle opening 11 does not need to be formed in a long hole extending up and down. In the present embodiment, the nozzle opening 11 is formed in a horizontally long shape. However, the size of the nozzle opening 11 is reduced to the extent that the nozzle opening 11 does not need to be formed long in the vertical direction. The size can be made relatively small, the appearance is good, and the possibility that external water may enter the nozzle opening 11 can be prevented. Further, if two motors M are used as means for rotating the cover case 1, small motors with relatively small outputs can be used as the motors M. Therefore, it is no longer necessary to form a large portion of the cover case 1 in which the motor M is accommodated, and the cover case 1 has a narrow shape over its entire length, has a good appearance and occupies a large mounting space. Can not be.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each part of the attachment structure of the attachment device to the air conditioner according to the present invention can be varied in design in various ways.

  As already described, the air conditioner is not limited to a bathroom heater, and the attached device is not limited to a mist generating device. As the air conditioner, for example, a general indoor air conditioner can be used. In addition, the air conditioner is not limited to a wall-mounted type, but may be a ceiling-mounted type. As the accessory device, various devices can be applied regardless of whether or not the device is related to air conditioning.
