Description

  The present invention relates to a wall-mounted bathroom air conditioner attached to a side wall of a bathroom and used for heating or drying the bathroom.

  As a wall-mounted bathroom air conditioner, a fan and a heat exchanger are accommodated in a casing attached to a side wall of the bathroom, and the bathroom air sucked into the casing by the fan is heated by the heat exchanger. (For example, refer to Patent Document 1). In such a bathroom air conditioner, a heat exchanger in which warm water is circulated is often used. When such a heat exchanger is used, in order to supply hot water from the outside to this heat exchanger, it is necessary to connect an external pipe for supplying hot water to the heat exchanger. As this pipe connecting means, there is means for connecting one end side of the external tube body and the tube portion of the heat exchanger in the casing by drawing one end side of the external tube body into the casing. According to such means, for example, when the front side of the casing is opened by removing the front cover of the casing or the like, the connection operation between the outer tube body and the tube portion of the heat exchanger and the detachment operation thereof are performed on the front surface of the casing. It becomes possible to carry out easily.

  However, the conventional bathroom air conditioner has to be improved as described below.

  That is, when performing maintenance of the bathroom air conditioner, the connection state between the external tube and the heat exchanger tube may be released, but at that time, the end of the external tube or the heat exchanger tube Water overflows from the club. On the other hand, in the casing of the bathroom air conditioner, there are provided electrical components such as a motor for operating each part such as a fan and an electrical board for controlling the operation thereof. Therefore, conventionally, there is a possibility that the water overflowing when the connection state between the external tube body and the tube portion of the heat exchanger is released will be applied to the above-described electrical component. In addition, in the past, even in the normal time when the external tube body and the tube portion of the heat exchanger are connected, in the unlikely event that a connection failure occurs in that portion, There was a possibility that water might be applied to the electrical component described above. From the viewpoint of reliably preventing failure of electrical components, it is desirable to eliminate the above-described concerns.

As shown in FIG. 1, the bathroom air conditioner A of this embodiment has the structure by which the fan 2 and the heat exchanger 3 were accommodated in the casing 1 attached to the side wall 9 of a bathroom. As shown in FIG. 2, the bathroom air conditioner A is configured such that an electrical board storage box 4 that houses an electrical board 40 is further housed in the casing 1. The electrical board 40 constitutes a control circuit that performs operation control of each part of the bathroom air conditioner A, and corresponds to an example of an electrical component in the present invention. As best shown in FIGS. 3 and 4, the casing 1 is provided with a water receiving guide 5. Hereinafter, the configuration of each unit described above will be described in more detail.

  The casing 1 is made of a synthetic resin, and includes a casing body 10 having a front opening shape and a front cover 11 that closes a front opening portion of the casing body 10. As shown in FIG. 1, as means for attaching the casing 1 to the side wall 9, for example, an attachment plate 8 attached to the side wall 9 using a screw body 80 a is used. The upper part of the rear part of the casing 1 is hooked on the upper part of the mounting plate 8, and the fixing piece 19 on the lower rear side of the casing 1 is connected to the lower part of the mounting plate 8 using a screw body 99a. ing. A plurality of air inlets 17 are provided in the upper portion of the casing 1, and a blower port 18 is provided in the lower front portion of the casing 1.

The heat exchanger 3 is divided into, for example, three blocks 30a to 30c, all of which are provided with a large number of metal fins 31 around a heat transfer tube (not shown) for circulating hot water. It has a configuration. This heat exchanger 3 is assembled to the casing main body 10 so as to surround the upper side and the front side of the fan 2. The heat exchanger 3 is provided with a pair of internal tubes 32 for connecting the heat exchanger 3 to a pair of external tubes 7 described later. These internal tubes 32 may be integrated with or separated from the heat transfer tubes of the heat exchanger 3. These internal tubes 32 are appropriately provided with an electromagnetic on-off valve 33 for turning on / off the supply of hot water to the heat exchanger 3.

  As shown in FIG. 4, a pipe opening 13 for drawing one end side of each external tube 7 into the casing 1 is formed in the back surface portion 12 of the casing 1. Each external tube body 7 is connected to a heat source device (not shown) such as a hot water supply device installed outside the bathroom at the other end, and is passed through a through hole 91 provided in the side wall 9 of the bathroom. Thus, the one end 7 a is drawn into the casing 1 by being drawn into the inside from the outside of the bathroom and further passing through the piping opening 13 from behind the casing 1. Each outer tube body 7 is connected to the inner tube body 32 in the casing 1, and this causes the supply of hot water from the heat source device to the heat exchanger 3 and the temperature to pass through the heat exchanger 3. It is possible to return the heated water to the heat source device and reheat it. The drawing does not show specific means for connecting the outer pipe body 7 and the inner pipe body 32, but various means such as a conventionally known pipe joint are used as this means. be able to.

  The water receiving guide 5 is integrally formed with the casing 1, and a plate-like portion 50 that protrudes from the lower edge portion of the piping opening 13 toward the front of the casing 1 in the back surface portion 12 of the casing 1, The plate-like portion 50 has a pair of upright walls 51a and 51b that rise upward from both side edges in the width direction (see FIG. 3). A connection point J between the outer tubular body 7 and the inner tubular body 32 is located on the plate-like portion 50. As a result, in the unlikely event that water leaks at the connection point J, the plate-like portion 50 receives this water and guides it to the piping opening 13 and discharges it from the piping opening 13 to the back of the casing 1. It is possible to make it. As shown in FIG. 4, the upper surface of the plate-like portion 50 is inclined by an appropriate angle α so as to be lower toward the rear portion of the casing 1, and water can be smoothly guided to the piping opening 13. It is. The pair of upright walls 51 a and 51 b serve to prevent water on the plate-like portion 50 from flowing down from both side edges of the plate-like portion 50 in the width direction.

  The electrical board storage box 4 is disposed on one side in the width direction of the heat exchanger 3 and below the water receiving guide 5. As shown in FIG. 4, the convex portion 41 provided on the upper portion of the electrical board storage box 4 is brought into contact with the front surface portion of the water receiving guide 5 and screwed into the screw hole 52 formed in the front surface portion. It is fixed to the water receiving guide 5 using a screw body 99b. On the other hand, the engaging portion 42 provided at the lower portion of the electrical board storage box 4 enters the hole portion 14 formed in the back surface portion 12 of the casing 1 and engages with the peripheral edge portion of the hole portion 14. . With this structure, the electrical board storage box 4 is attached to the casing 1.

  Next, the operation of the bathroom air conditioner A will be described.

  First, even if water leakage occurs in the connecting portion J due to reasons such as the piping work of the outer tube body 7 and the inner tube body 32 being not properly performed, the water is received by the water receiving guide 5 After being received by the plate-like portion 50, it is guided to the piping opening 13 and discharged from this portion to the back of the casing 1. Moreover, for the purpose of performing maintenance of the bathroom air conditioner A, the connection between the external pipe body 7 and the internal pipe body 32 may be released. In such a case, when water overflows from those parts. In addition, this water is also received by the water receiving guide 5 and discharged from the piping opening 13 to the back of the casing 1. After that, this water flows downward along the side wall 9 of the bathroom. However, in the case of the bathroom, there is no problem even if such drainage is performed.

  As described above, if water is discharged behind the casing 1 using the water receiving guide 5, it is possible to prevent water from flowing down onto the electrical board storage box 4. Although the electrical board storage box 4 protects the electrical board 40 so that the electrical board 40 does not easily get wet with water, the electrical board storage box 4 has a vent hole for heat dissipation and the like to ensure the protection of the electrical board 40. From the viewpoint of achieving this, it is desired to avoid as much as possible that water flows down on the electrical board storage box 4. According to this bathroom air conditioner A, it will be possible to accurately meet such a demand.

  In particular, in the present embodiment, as described with reference to FIG. 4, the upper surface of the plate-like portion 50 of the water receiving guide 5 is inclined downwardly, so that it faces the pipe opening 13. Water flows smoothly. In addition, since the pair of upright walls 51a and 51b serves to prevent water from flowing down from both side edges of the plate-like portion 50, it is possible to more reliably prevent water from flowing down on the electrical board storage box 4. It becomes.

  Moreover, in this bathroom air conditioner A, since the opening part 13 for piping for letting the external tube 7 pass is utilized as an opening part for discharging water to the exterior of the casing 1, it drains into the casing 1. There is no need to provide a separate opening. Therefore, the structure of the casing 1 is appropriately prevented from becoming complicated. Since the water receiving guide 5 is integrally formed with the casing 1, the water receiving guide 5 can be easily manufactured, and an increase in manufacturing cost can be suitably suppressed.

  As shown in FIG. 4, the mounting structure of the electrical board storage box 4 is such that the engaging portion 42 enters and engages with the hole 14 of the casing 1 and the convex portion 41 utilizes the screw body 99b. Since the structure is screwed to the receiving guide 5, it is easy to attach and remove the electrical board storage box 4 to the casing 1. In addition, since the water receiving guide 5 is used as the mounting bracket, the structure is rational, and it is more preferable to avoid complication of the structure of the casing 1.

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

  The water receiving guide referred to in the present invention is configured to have a function of receiving and discharging the water from the connection portion between the outer tube and the inner tube after the water is received. The specific shape is not specified. For example, it can also be formed in the shape of a bowl having a circular arc shape with an open top. Further, the water receiving guide can be formed separately from the casing.
