Description

  The present invention relates to a structure for attaching a functional unit, for example for bath cleaning, to a desired wall in a bathroom.

The applicant has previously proposed the structure described in Patent Document 1 as an example of the mounting structure of the functional unit.
In the construction described therein, for example, functional units for bath cleaning are attached to the wall of the bathroom by means of upper and lower brackets. The functional unit for bathtub cleaning has a configuration in which various fluid devices, a detergent charging valve, and the like are incorporated in a case. In this functional unit, it is possible to generate detergent liquid (washing water) by mixing detergent with hot water supplied from a water heater, and to supply the detergent liquid to a washing nozzle installed in a bath. is there. The upper and lower brackets have holes or the like engageable with the projections provided on the functional unit, and the functional unit can be held with its one side in contact with the wall of the bath It is possible. By bringing the functional unit into contact with the wall of the bath, it is possible to increase the stability of the functional unit.

  However, in the prior art, there is still room for improvement as follows.

That is, since the functional unit is attached in contact with the wall of the bathtub, for example, a situation occurs in which the opening and closing operation of the on-off solenoid valve incorporated in the functional unit is repeated multiple times, and the functional unit vibrates , This vibration is directly transmitted to the wall of the bathtub. As a result, a collision noise (vibration noise) is easily generated between the functional unit and the wall of the bathtub. Such collision noise is annoying to the user and it is desirable to prevent it properly.
Also, if the functional unit is mounted in contact with the wall of the bathtub, in winter when the outside air temperature is low, the functional unit is cooled by the outside air through the wall of the bathtub and condensation occurs in the functional unit There is also a fear. Since dew condensation in the functional unit may adversely affect the electric devices incorporated in the functional unit, it is also desirable to appropriately prevent this.

  The present invention has been conceived under the circumstances as described above, and provides a mounting structure of a functional unit in a bathroom capable of appropriately preventing or suppressing a defect such as vibration noise of the functional unit. Is the problem.

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

The mounting structure of a functional unit provided in a bathroom according to the present invention includes a bracket mounted so as to project to the front side from a mounting target wall in the bathroom, a desired device incorporated in the case, and the mounting target wall And a functional unit held by the bracket in a noncontacting manner and separated from each other, wherein the mounting structure of the functional unit in the bathroom , the upper surface and the lower surface of the functional unit face upward And a lower convex portion facing downward, and the lower bracket and the upper bracket formed integrally or separately from the lower bracket are provided as the brackets. The bracket is provided with a lower fixing plate portion fixed to the mounting target wall portion, and a projection from the lower fixing plate portion to the front side of the mounting target wall portion And a receiving plate portion for mounting the functional unit, and the lower projection portion provided on the receiving plate portion so as to separate the lower side of the functional unit from the mounting target wall portion. It has a lower positioning hole which can be positioned, and the upper bracket includes an upper fixing plate fixed to the mounting object wall, and the mounting object wall from the upper fixing plate. A support plate portion projecting to the front side, and a support plate portion provided on the support plate portion and positioned such that the upper side of the functional unit is separated from the attachment target wall portion by the upper convex portion being inserted. An upper positioning hole portion or a downward opening-like positioning recess portion, and is provided on the lower bracket so as to stand upward from the receiving plate portion, and the machine When the unit is placed on the receiving plate portion of the lower bracket from one side thereof, the function is to prevent the lower convex portion from moving beyond the location where the lower positioning hole is formed. The auxiliary hole which can be contacted to the lower positioning hole in the stopper part which can further be contacted to one side of the unit and which has the stopper part, and which can make the lower convex part fit It is characterized in that a unit is provided .

According to such a configuration, since the functional unit is not in contact with the mounting target wall, even if the functional unit vibrates due to the operation of the device incorporated in the functional unit, etc. Vibration is not transmitted directly to the mounting wall. There is no collision noise between the functional unit and the mounting target wall. Therefore, the offensive noise resulting from the vibration of the functional unit can be suitably reduced.
Further, in the prior art, when the wall to which the functional unit is attached is the wall of the bathtub, the functional unit is cooled by the outside air through the bathtub wall in winter when the outside air temperature is low. According to the present invention, the functional unit is not cooled by the outside air through the wall of the bathtub. Therefore, it is possible to preferably eliminate the possibility of condensation occurring in the functional unit.
In addition, according to the present invention, it is also possible to pass the wiring cord and the piping member through the gap between the functional unit and the mounting target wall.

Moreover, according to such a configuration, the functional unit can be held in a state of being separated from the mounting target wall by using the upper bracket and the lower bracket having a simple structure. The upper protrusion of the functional unit is fitted into the upper positioning hole or downward opening positioning recess of the upper bracket, and the lower protrusion is fitted in the lower positioning hole of the lower bracket Therefore, proper positioning and holding of the functional unit is possible.

Furthermore , according to such a configuration, it is possible to facilitate and ensure the operation of inserting the lower convex portion of the functional unit into the lower positioning hole of the lower bracket. When the functional unit is mounted in a narrow space of a bathroom, it is difficult for the operator to clearly confirm the positions of the lower convex portion and the lower positioning concave portion of the functional unit. On the other hand, according to the configuration described above, the lower convex portion can be easily made into the lower positioning concave by using the stopper portion as a guide for fitting the lower convex portion into the lower positioning concave. It will be possible to insert properly.

Furthermore, according to such a configuration, the configuration can be simplified as compared with the case where the stopper portion is provided separately from the lower bracket. Further, if the stopper portion is provided in a state of being erected upward from the receiving plate portion, one side surface of the functional unit can be easily brought into contact with the stopper portion when the functional unit is mounted on the receiving plate portion of the lower bracket. Thus, the workability of the positioning operation of the functional unit using the stopper portion can be further improved.

Furthermore, according to such a configuration, when the functional unit is placed on the receiving plate portion of the lower bracket, after the lower convex portion of the functional unit is fitted into the auxiliary hole, the lower convex in the auxiliary hole portion By moving the portion, it is possible to finally arrange the lower convex portion in the lower positioning hole. For this reason, the operation of inserting the lower convex portion into the lower positioning hole is further facilitated.

  In the present invention, preferably, the functional unit has a substantially rectangular parallelepiped shape in which the lateral width dimension on the left and right is larger than the width dimension in the front and rear direction, and the front and rear portions of the functional unit It is attached in the direction which becomes almost parallel to the part.

  According to such a configuration, it is possible to prevent the functional unit from protruding in a large and bulky state from the mounting target wall. Moreover, it is preferable also in stabilizing the mounting state of the functional unit.

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

It takes place. Drainage from the relief valve 56 is performed via the pipe 56a.

  As a means for mounting the functional unit U, an upper convex portion 43 and a lower convex portion 44 are provided at positions near one end of the upper surface portion of the case 4 and one end of the bottom surface portion. The upper convex portion 43 and the lower convex portion 44 are resin-molded integrally with the case main body 40. The upper convex portion 43 is upwardly convex, and as shown in FIG. 3A, for example, is U-shaped in a plan view, and includes a front wall portion 43a and side wall portions 43b. The lower side convex part 44 is convex downward, and as shown to FIG. 3B, it is a shape substantially rectangular shape in a bottom view, or a shape close | similar to this.

In FIGS. 1 and 2, the upper bracket 1 and the lower bracket 2 are formed by pressing a metal plate or the like, and are fixed to the wall 3 of the bathroom using a screw body 90 such as a screw. Is attached.
The functional unit U has a substantially rectangular parallelepiped shape in which the lateral width Lb on the left and right is larger than the width La in the front-rear direction, but the upper side bracket 1 and the lower side bracket 2 Can be attached in a direction substantially parallel to the wall 3 of the bathroom. In the mounted state of the functional unit U, a gap 39 of an appropriate width Lc is formed between the functional unit U and the bathroom wall 3 so that the bathroom wall 3 and the functional unit U are not in contact with each other. It has become.

In FIG. 2, the upper bracket 1 is in contact with the wall 3 of the bathroom and fixed by the screw body 90 to the upper fixing plate 10, and a support projecting from the upper fixing plate 10 to the front side of the wall 3 of the bathroom A plate portion 11 and a substantially reverse U-shaped bending portion 12 continuously provided in a tip end region of the support plate portion 11

The upper convex portion 43 (strictly, the front wall 43a of the upper convex portion 43) of the functional unit U can be fitted into the positioning concave portion 13 from the lower side, and when it is fitted, as shown in FIG. As shown in the phantom line a), the bending portion 12 is sandwiched between the side wall portions 43 b of the upper side convex portion 43. As a result, the functional unit U can be positioned in the front-rear direction.

  In FIG. 2, the lower bracket 2 is in contact with the wall 3 of the bathroom and fixed by the screw body 90, and from the lower fixing plate 20 to the front side of the wall 3 of the bathroom It has a receiving plate portion 21 for protruding and carrying the functional unit U, and a stopper portion 22 standing upward from one side edge of the receiving plate portion 21. The lower positioning portion for fitting the lower convex portion 44 of the functional unit U at a position away from the lower fixed plate portion 20 to the front side in the receiving plate portion 21 for positioning the lower convex portion 44 A hole 23 is provided. The stopper portion 22 abuts on the functional unit U when the functional unit U is placed on the receiving plate portion 21 from one side thereof, so that the lower convex portion 44 forms the location where the lower positioning hole portion 23 is formed. It is a part to prevent moving beyond. For example, the stopper portion 22 has a plate shape similar to that of the receiving plate portion 21, and an auxiliary hole portion 24 communicating with the lower positioning hole portion 23 is provided on the lower side of the stopper portion 22. There is. The size and shape of the auxiliary hole 24 are the same as those of the lower positioning hole 23. The stopper portion 22 can also be used as a receiving plate portion for supporting the functional unit U when the lower bracket 2 is used after being horizontally reversed as described later with reference to FIG.

  Next, the operation of the mounting structure C1 described above will be described.

The functional unit U can be attached easily by the following operation.
That is, in a state in which the upper bracket 1 and the lower bracket 2 are attached to the wall 3 of the bathroom, first, as shown in FIG. Next, the lower side of the functional unit U is moved to abut against the stopper portion 22 while the upper convex portion 43 is inserted into the positioning concave portion 13. Lowering the functional unit U in this contact state allows the lower convex portion 44 to be fitted into the lower positioning hole portion 23 and places the bottom of the functional unit U on the receiving plate portion 21. Can. As described above, when attaching the functional unit U to the upper bracket 1 and the lower bracket 2, connecting members such as bolts and nuts and tools are not necessary, and the attaching operation of the functional unit U can be performed easily and quickly. It is possible. Therefore, it is also suitable when the installation point of the functional unit U is, for example, a narrow space between the bathtub and the bathtub apron. The operation of removing the functional unit U from the upper bracket 1 and the lower bracket 2 is also easy.
When performing the mounting operation described above, the position of the lower positioning portion 24 of the lower convex portion 44 and the lower positioning hole portion 23 of the receiving plate portion 21 is difficult for the operator to understand, but the lower convex portion 44 is The mounting workability of the functional unit U is better because the insertion into the lower positioning hole 23 is facilitated.

  When the functional unit U is to be brought into contact with the stopper portion 22, the lower convex portion 44 may be fitted into the auxiliary hole portion 24. However, in such a case, the functional unit U is moved from the position of the auxiliary hole 24 to the position of the lower positioning hole 23 without escaping the lower convex portion 44 from the auxiliary hole 24. You can move it. Therefore, the operation of inserting the lower convex portion 44 into the lower positioning hole portion 23 is further facilitated.

In the attached state of the functional unit U shown in FIG. 1, the weight of the functional unit U is received by the receiving plate portion 21 of the lower bracket 2. In addition, the horizontal positioning of the functional unit U can be properly achieved by the fitting action of the lower convex portion 44 and the lower positioning hole 23 of the functional unit U. Furthermore, since the upper convex portion 43 of the functional unit U is fitted into the positioning recess 13 of the upper bracket 1, the tilting of the functional unit U can be prevented, and the horizontal positioning of the upper side of the functional unit U can be achieved. . Therefore, it is possible to support the functional unit U in a stable state.

  As described with reference to FIG. 1 (a), a gap 39 is formed between the functional unit U and the wall 3 of the bathroom, and both are in a non-contact state. Therefore, for example, as a result of the pouring solenoid valve (open / close valve) 54 of the functional unit U repeating opening and closing operations, even if the functional unit U vibrates, the vibration is not directly transmitted to the wall 3 of the bathroom . The collision noise between the functional unit U and the wall 3 of the bathroom due to the vibration of the functional unit U does not occur. For this reason, it is possible to prevent as much as possible generation of offensive noise when the functional unit U vibrates. In addition, in winter when the outside air temperature is low, cooling of the functional unit U by the outside air via the wall 3 of the bathroom is also avoided. Therefore, the possibility that dew condensation occurs in the functional unit U can be eliminated.

6 to 12 (except for FIGS. 8 to 11) show another embodiment of the present invention. In these figures, elements which are the same as or similar to those of the above-described embodiment are denoted by the same reference numerals as those of the above-described embodiment, and redundant description will be omitted.

  In the mounting structure C2 shown in FIG. 6, the orientation (the orientation of the wall 3 of the bathroom) of the attachment of the functional unit U to the wall 3 of the bathroom is opposite to that of the embodiment shown in FIGS. ing. The upper bracket 1A in the present embodiment is laterally symmetrical to the upper bracket 1 of the above embodiment. On the other hand, the lower bracket 2 has the same configuration as the lower bracket 2 of the embodiment, and the whole is horizontally reversed and rotated by 90 ° as compared with the lower bracket 2 of the embodiment. Is attached to the wall 3 of the bathroom. For this reason, in the embodiment shown in FIGS. 1 and 2 and the present embodiment, the receiving plate portion 21 and the stopper portion 22 of the lower bracket 2 are replaced with each other, and the receiving plate portion 21 of the embodiment is It becomes the stopper portion 22 in the embodiment, and the stopper portion 22 of the embodiment is used as the receiving plate portion 21.

  Preferably, as shown in FIG. 7, for the lower fixing plate portion 20 of the lower bracket 2, the hole portions 20 a and 20 b for screw body insertion are 45 ° from the corner portion 25 of the lower fixing plate portion 20. It is configured to be located on the angle line L. According to such a configuration, screwing of the lower bracket 2 in the relationship between the screwing holes 10a and 10b of the upper bracket 1 (or 1A) in the case of the embodiment and the case of the present embodiment The relative positions of the hole portions 20a and 20b for the second embodiment become constant in the case of the above embodiment and in the case of the present embodiment, and alignment work with the upper bracket (or 1A) and the lower bracket 2 Can be facilitated.

  As described above, the lower bracket 2 can be used as it is even when the direction of attachment of the functional unit U to the bathroom wall 3 (the direction of the bathroom wall 3) is changed. Therefore, it is preferable to reduce the types of brackets to be prepared and to reduce the cost of parts.

  In the mounting structure C3 shown in FIG. 8, the upper positioning hole portion 15 is provided at a position apart from the upper fixing plate portion 10 in the support plate portion 11 of the upper bracket 1B, and the upper positioning hole portion 15 is provided. The upper convex part 43 of the functional unit U can be inserted from below. As for the lower bracket 2B, the stopper portion 22 in the previous embodiment is omitted, and the lower positioning hole portion 23 in the form of a through hole is provided in the receiving plate portion 22 and the lower portion of the functional unit U The side convex part 44 can be inserted. Even with such a configuration, it is possible to appropriately attach the functional unit U in a state of being separated from the wall 3 of the bathroom using the upper bracket 1B and the lower bracket 2B.

  In the embodiment shown in FIG. 9, the universal bush 8 is attached to the inner peripheral edge of the upper positioning hole 15 of the upper bracket 1B shown in FIG. The free bush 8 has a configuration similar to that described in, for example, Japanese Utility Model Application Publication No. 61-79421, and is a resin molded product excellent in bending and deformability. Since the upper bracket 1B is made of metal, when the upper projection 43 is in direct contact with the inner peripheral edge of the upper positioning hole 15, the upper projection 43 wears due to the vibration of the functional unit U, etc. May easily occur. On the other hand, according to the present embodiment, it is possible to appropriately prevent such a risk. Of course, the universal bush 8 can be attached to the inner peripheral edge of the lower positioning hole 23 of the lower bracket 2B shown in FIG.

  When attaching the universal bush 8 to the upper bracket 1B (or lower bracket 2B), it is preferable to replace the upper positioning hole 15 with a rectangular shape and to form an oblong shape. When the upper positioning hole 15 is rectangular, as shown in FIG. 11A, when the start end 8a of the free bush 8 is in the long side 15a of the upper positioning hole 15, As shown in FIG. 6B, a large difference occurs in the attachment state of the free bush 8 when the start end 8a is in the short side 15b of the upper positioning hole 15 (reference numeral 8b indicates the end). . In the case of FIG. 6A, the number of bent portions R of the flexible bush 8 is four in total, whereas in the case of FIG. 6B, the bent portions R of the flexible bush 8 is a total of 3 places. It is because On the other hand, as shown in FIG. 10, in the case where the upper positioning hole 15 is oval, it is practically difficult to position the starting end 8a of the flexible bush 8 on the rounded side edges 15c. For this reason, it is necessary to arrange the starting end 8a of the flexible bush 8 at the position of the linear long side portion 15a, and it is possible to preferably achieve stabilization and optimization of the attachment mode of the flexible bush 8 .

  In the attachment structure C4 shown in FIG. 12, the front part 46a and the back part 46b of the functional unit U are set to be in a direction substantially orthogonal to the wall 3 of the bathroom, and the upper bracket 1C and the lower side The bracket 2C is configured to be capable of such attachment. Also in the present embodiment, by forming the gap 39 of the appropriate width Lc between the functional unit U and the bathroom wall portion 3, it is possible to obtain a noise reduction effect etc. when the functional unit U vibrates. It is. As understood from the present embodiment, the mounting direction of the functional unit U is not limited.

  The present invention is not limited to the contents of the embodiments described above. The specific configuration of each part of the mounting structure of the functional unit in the bathroom according to the present invention can be varied in design variously within the intended scope of the present invention.

The upper bracket and the lower bracket may not be formed separately from each other, and may be formed in an integrally connected state.
