Description

  The present invention relates to a warm water unit in which warm water related equipment is incorporated into an outer case and unitized.

  The present applicant has previously proposed the one described in Patent Document 1 as an example of the hot water unit. In the hot water unit described in the same document, a hot water related device is accommodated in an outer case, and a control unit having an electrical board is fixed in the outer case on the front side of the hot water related device. It is attached. Therefore, when the front surface side of the exterior case is opened, the control unit can be easily operated and inspected. Further, the hot water unit is configured such that when the control unit is removed, the control unit can be hooked in a reversed direction at a position retracted from the front surface portion of the outer case. For this reason, when performing maintenance of hot water related equipment, it is possible to prevent the control unit from getting in the way and improve workability. If the control unit is turned upside down, the operator can be prevented from accidentally touching the front portion of the control unit, and the control unit can be protected.

  However, in the prior art, in order to retract the control unit from the front area of the hot water-related device, it is necessary to lift the control unit and take it out of the outer case after releasing the fixed state of the control unit. Therefore, this work is somewhat troublesome, and it is desired that this point be further improved. However, in this case, it is also desired to avoid as much as possible the increase in the manufacturing cost of the hot water unit.

JP 2009-192167 A

  The present invention has been conceived under the circumstances as described above, and provides a hot water unit that is easy to handle a control unit and can appropriately avoid an increase in manufacturing cost. That is the issue.

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

The hot water unit provided by the present invention includes an outer case that accommodates a hot water-related device having a hot water generating function or a hot water storage function, and an outer case that is disposed on the front side of the hot water-related device in the outer case. A hot water unit that is supported by the member and that controls the hot water-related device, the shaft provided on the support member and the control unit, and fitted to the shaft By having a hole to be joined, the control unit can be rotatably supported around the shaft, and the control unit closes a region on the near side of the hot water-related equipment, A rotation support portion that enables switching between an open state in which a region on the near side is opened, and when the control unit is in the closed state, the control unit is configured to have the shaft portion and the hole portion. And regulating means for regulating that positional deviation in the fitting direction of, and wherein the control unit, together comprises a first bracket having a first horizontal plate portion, said support member, said The first horizontal plate portion has a second metal fitting having a second horizontal plate portion on which the first horizontal plate portion is placed on the upper surface, and the shaft portion is screwed to one of the first and second horizontal plate portions. It is constituted by screwing a body, and the restricting means has a protrusion formed by cutting and raising one of the first and second metal fittings. Yes.

  According to such a configuration, when performing maintenance or the like of the hot water related equipment located on the back side of the control unit, the control unit is brought into a state where the front side region of the hot water related equipment is closed from the closed state. In this case, the control unit may be rotated while being supported by the rotation support portion. Unlike the prior art, it is not necessary to lift the control unit and take it out of the outer case after releasing the fixed state of the control unit. Therefore, handling of the control unit is facilitated, and workability such as maintenance is further improved as compared with the conventional case. Further, as an important effect, the rotation support portion that rotatably supports the control unit has a structure in which the shaft portion and the hole portion are fitted, and the structure can be very simple. On the other hand, if the shaft and hole are simply fitted together, there is a risk that the control unit will rattle during transportation of hot water-related equipment. Is done. This restricting means may be any means that restricts the position of the control unit from being displaced in the fitting direction between the shaft portion and the hole when the control unit is in the closed state. Can do. For this reason, according to the present invention, it is possible to appropriately avoid an increase in the manufacturing cost of the hot water unit.

Furthermore , according to such a configuration, the effects intended by the present invention can be obtained by a simple structure in which the first and second metal fittings and the screw body are combined, and the manufacturing cost can be reduced. More preferred above.

  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.

It is a principal part disassembled perspective view which shows the other example of this invention.

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

  1 to 5 show an example of a hot water unit to which the present invention is applied. As shown well in FIGS. 1 and 2, the hot water unit U of the present embodiment includes an outer case 1, a front cover panel 18, hot water-related equipment 2 and a control unit 3 housed in the outer case 1, and A pair of upper and lower rotation support portions C that support the control unit 3 are provided.

The outer case 1 is a substantially rectangular parallelepiped with an opening 10 formed in the front surface, and is formed using, for example, a thin metal plate. In the normal case, the outer case 1 has a front cover panel 18 attached to the front surface thereof using screwing means or the like, and the opening 10 is closed.

  Although the details of the hot water-related device 2 are omitted in the drawings, for example, a hot water storage tank, an instantaneous water heater, and devices used attached thereto are used. However, it is not limited to these as described later. This hot water-related device 2 is accommodated in a position near the inner part of the outer case 1. The control unit 3 has a configuration in which an electrical board 30 equipped with a control circuit for executing operation control of the hot water related equipment 2 is attached to a flat case-shaped holder 31. The control unit 3 is arranged on the front side of the hot water related device 2 in the outer case 1.

  As shown in FIGS. 3-5, each rotation support part C is comprised combining 1st metal fittings 4A and 4B. 4 A of 1st metal fittings are attached to the one side part of the holder 31 of the control unit 3 using the screw body 91, and have the 1st horizontal board part 40a of planar view substantially rectangular shape. A screw body 5 is screwed onto the first horizontal plate portion 40a, and a part of the screw body 5 projects below the first horizontal plate portion 40a. This protruding portion is the shaft portion 50 and serves as the rotation center of the control unit 3.

  The second metal fitting 4B corresponds to an example of a support member in the present invention, and is attached to the column 11 in the exterior case 1. This support | pillar 11 is located in the edge part of the front-surface opening part 10 of the exterior case 1, and stood up and down, and the rigidity is high. The 2nd metal fitting 4B has the 2nd horizontal board part 40b connected to the backplate part 41 welded to the support | pillar 11, and the projection part 42 for stoppers. The second horizontal plate portion 40b is a portion for receiving the first metal fitting 4A, and the first horizontal plate portion 40a is placed on the second horizontal plate portion 40b. The second horizontal plate portion 40b is provided with a hole portion 43 into which the shaft portion 50 is fitted. With these fitting actions, the control unit 3 can rotate in the substantially horizontal direction around them. Thereby, the control unit 3 can be switched between a closed state in which the near side region of the hot water related device 2 is closed and an open state in which the region is opened. Here, the “closed state” means a state in which the control unit 3 faces substantially in the front direction of the outer case 1 and closes the near side region of the hot water related equipment 2 as shown by the solid line in FIGS. 1 and 2. It is. The near side region need not be fully closed. On the other hand, the “open state” means that the control unit 3 rotates to the front side of the outer case 1 as shown by the phantom lines in FIG. 1 and FIG. It is in the state. This “open state” does not need to be a so-called fully open state. In short, it suffices that the area on the near side of the hot water-related device 2 is more open than the “closed state” described above.

  The projecting portion 42 is a portion for preventing the control unit 3 from floating upward, and corresponds to an example of a regulating means in the present invention. In the present embodiment, when the control unit 3 is in the closed state, the other side edge side of the control unit 3 can be fixed to the column 11a using the screw body 90 (see FIG. 1). . However, even if only one side of the control unit 3 is fixed in this way, there is a possibility that the control unit 3 will rattle on the side where the rotation support portion C opposite to that is provided. The protrusion 42 is for eliminating such a concern.

  The protrusion 42 forms a gap c1 with the upper surface of the second horizontal plate portion 40b. The gap c1 is a part for allowing the first horizontal plate portion 40a to enter. The state where the first horizontal plate portion 40a enters the gap c1 is only when the control unit 3 is closed. It is set to occur. The protrusion 42 is integrally provided on the second metal fitting 4B by cutting and raising the second metal fitting 4B. Of course, these can also be provided separately.

  Next, the operation of the hot water unit U will be described.

  First, in order to attach the control unit 3 in the exterior case 1 from the state shown in FIG. 4, the shaft portion 50 is fitted into the hole 43 as shown in FIG. 3, and the first horizontal plate portion 40a is inserted. May be placed on the second horizontal plate portion 40b. Thereby, the control unit 3 is appropriately supported by the second metal fitting 4B. Since the protruding portion 42 is offset by an appropriate distance from the fitting position between the shaft portion 50 and the hole portion 43, the protruding portion 42 can be prevented from hindering the assembly of the control unit 3.

  The control unit 3 can rotate around the shaft portion 50 and can be switched between a closed state in which the near side region of the hot water-related device 2 is closed and an open state in which the control unit 3 is opened as described above. When performing maintenance of the hot water-related equipment 2, it is necessary to open the front side region of the hot water-related equipment 2, but this operation can be easily performed by rotating the control unit 3. There is no need to remove the control unit 3 from the support 11 and take it out of the outer case 1. On the other hand, in the normal time, the control unit 3 is closed. At this time, the first horizontal plate portion 40a enters the gap c1 between the protrusion 42 and the second horizontal plate portion 40b. (See FIG. 5). Thus, the control unit 3 is prevented from floating upward, and for example, the control unit 3 can be prevented from rattling when the hot water unit U is transported or at other times. Of course, the shaft portion 50 is also appropriately prevented from coming off from the hole portion 43.

  On the other hand, the rotation support portion C is configured using the first metal fittings 4A and 4B having a simple configuration, and the number of parts is small, and the overall configuration is simple. Also, expensive parts are not used. For this reason, the manufacturing cost of the rotation support part C can be reduced.

  6 and 7 show another embodiment of the present invention. In these drawings, elements that are the same as or similar to those in the above embodiment are given the same reference numerals as in the above embodiment.

  In the embodiment shown in FIG. 6, the screw body 5 is attached to the second horizontal plate portion 40 b to form the shaft portion 50, and the hole portion 43 fitted to the shaft portion 50 has the first horizontal portion. It is provided on the plate portion 40a. As will be understood from the present embodiment, in the present invention, it does not matter which side of the control unit side and the support member side each of the shaft portion and the hole portion to be fitted to each other is provided.

  In the embodiment shown in FIG. 7, the protrusion 42 is provided on the first metal fitting 4A, and when the control unit 3 is closed, the protrusion 42 and the first horizontal plate 40a The second horizontal plate portion 40b is configured to enter the gap c1. Even with such a configuration, it is possible to prevent the control unit 3 from being lifted. As can be understood from the present embodiment, the restricting means in the present invention may be provided on either the control unit side or the support member side.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each part of the hot water unit according to the present invention can be varied in design in various ways.

  The rotation support portion and the regulating means in the present invention are preferably configured using a screw body and a set of metal fittings as in the above-described embodiment, but are not limited thereto. For example, the shaft portion or the hole that fits into the shaft portion may be directly provided in the control unit without using a metal fitting. As described above, the restricting means may be provided separately from the metal fittings constituting the rotation support portion.

  The hot water-related device referred to in the present invention means a device having a hot water generating function or a hot water storage function, but its specific type and number are not limited. In addition to the hot water storage tank and the instantaneous water heater, for example, a heat pump and a cogeneration system device also correspond to the hot water related device. Therefore, the hot water unit according to the present invention can be configured as, for example, a hot water storage tank unit, a water heater unit, a heat pump unit, a cogeneration system, and the like. The control unit referred to in the present invention is a unit having a function of controlling hot water related equipment, and its specific configuration is not limited.
