Description

  The present invention relates to a structure of a housing for outdoor installation such as a water storage tank for a water heater or an outdoor unit of an air conditioner, and particularly relates to a housing for outdoor installation that can reduce dirt due to rain.

  The mainstream of storage tanks for water heaters and outdoor units for air conditioners installed in residential premises is a structure in which the housing is covered with a steel plate. These casings generally have a top plate structure in which a side plate surrounding the periphery is wrapped with a top plate from above. By adopting such a top plate structure, the rain that falls on the top plate flows to the surrounding side plates and is guided to the grounding surface through the side plates, so that the intrusion of rain water into the housing can be reduced.

  However, in this conventional structure, since the rainwater flows through the side plate, there is a problem that the side plate is contaminated by raindrops. In particular, a water storage tank equipped with a heat exchanger for a hot water heater using a refrigeration cycle, which has become a hot topic in recent years, has a height of 2 m or more. There are aesthetic challenges. Moreover, since these devices are often installed in a narrow site, they are in an environment that is difficult to clean. In the prior art, these large devices are generally given a color or the like in which stains are not noticeable. However, stains due to raindrops are streaked and are easily noticeable.

  In addition, in conventional examples such as outdoor units, in order to reduce dirt due to rain on the display label provided on the side of the housing, a proposal is made to form a protrusion on the top of the display label so that it does not flow on the display label. Has been made.

JP 2008-166337 A

  In the above conventional example, it is possible to reduce the dirt caused by rainwater on the display label provided on the side surface, but this structure is effective for preventing a part of the dirt, but it is impossible to prevent the whole casing from being stained. . In addition, a roof like a storeroom is a solution, but in order to return rainwater from this roof to the ground, a new structure such as a rain gutter and a roof that leads rain water to this gutter is prepared. It has to be complicated.

  Therefore, an object of the present invention is to provide a housing for outdoor installation that can reduce dirt due to raindrops using an existing structure of a housing structure.

  In the present invention, in order to achieve the above-mentioned object, in an outdoor installation housing formed to include a plurality of side plates and a top plate, rainwater is drained between the pair of side plates on the grounding surface of the outdoor installation housing. A drainage passage is formed, and a concave passage is formed on the top plate for guiding rain water falling on the top plate to the upper end of the drainage passage.

  According to the present invention, by forming a drainage passage between a pair of side plates by a simple simple past, it is possible to keep the accuracy of butting low and simplify the processing process and the assembly process. By providing a concave passage that guides rainwater to the ground, the strength of the top plate can be strengthened, and rainwater that falls on the top plate can be discharged to the ground surface via the drainage passage. Dirt can be reduced.

  Hereinafter, the outdoor installation housing according to the present invention will be described in detail with reference to FIGS. In the following description, a water storage tank with a heat exchanger of a hot water heater using a refrigeration cycle will be described as an example, but the present invention is not limited to this. 1 and 2 are the first embodiment, FIGS. 3 and 4 are the second embodiment, FIG. 5 is the third embodiment, FIG. 6 is the fourth embodiment, FIG. 7 is the fifth embodiment, FIG. Reference numeral 8 denotes the sixth embodiment. In addition, the same site | part, direction, etc. are shown with the same code | symbol, and the overlapping description is abbreviate | omitted.

  With reference to FIG. 1 and FIG. 2, the water storage tank for water heaters with the heat exchanger which concerns on the housing for outdoor installation of 1st Example is demonstrated concretely. Here, FIG. 1 is a schematic configuration diagram of a water heater storage tank according to the first embodiment. 2A and 2B are part development views of the water heater tank according to the first embodiment, wherein FIG. 2A is a part development view of the casing, and FIG. 2B is a cross-sectional view of the casing.

  1 and 2, a hot water storage tank generally indicated by reference numeral 1 includes a heat exchanger and a water supply tank, is connected to a water pipe, and includes a heat exchanger and a compressor (not shown). Heat is exchanged with the refrigerant, and the tap water taken from the water pipe is heated and supplied directly to domestic water supply facilities, or the tap water taken from the water pipe is heated and stored in the water storage tank. The stored hot water is then supplied to domestic waterworks.

  The water heater storage tank 1 includes a heat exchanger and a water tank (not shown) in a frame (not shown), and a plurality of side plates 100 and a top plate 200 are attached to the frame to constitute a housing 10 for outdoor installation. In the outdoor installation housing 10 according to this embodiment, the side plate 100 includes left and right side plate panels 101 and 102, front and rear front panels 103, and a back panel 104. The side plate panels 101 and 102 are formed so as to wrap around in the front-rear direction, and have a front-back symmetrical structure in which the front panel 103 and the back panel 104 are attached between the side plate panels 101 and 102 that wrap around the front and back surfaces. In this embodiment, an operation panel unit 20 that is not provided on the rear panel 104 is provided above the front panel 103. The operation panel unit 20 employs a structure in which a front portion thereof is covered with an opening / closing lid 21, and the operation switch (not shown) can be exposed and operated by releasing the opening / closing lid 21. Moreover, the top plate 200 employs a top plate structure in which a peripheral end portion covers the upper end portion of the side plate 100 by pressing or bending the steel plate.

  The major feature of the water heater storage tank 1 according to this embodiment is that it is an outdoor installation chassis 10 that can reduce dirt due to rain using an existing structure of a chassis structure.

  That is, the water heater storage tank 1 as in this embodiment has a large box-shaped appearance with a height of about 2 m, and is therefore installed in the corner of a detached house or on the veranda of an apartment house. The case that is done is common. Further, since this device is operated by a controller (not shown) installed indoors and does not require much maintenance, once installed, the device is not touched by the user.

  On the other hand, since the water heater storage tank 1 is a large casing, it has a wide side plate 100 around it, and rainwater hits the side plate 100, so that there is a problem that dirt due to these rainwaters adheres. In particular, dirt due to raindrops flowing through this large side plate 100 is conspicuous. Moreover, since the water heater storage tank 1 is a tall housing, the exterior of the outdoor installation housing 10 on which dirt due to raindrops is attached is easily visible from the outside of the house, and there is a problem that the appearance of the house is deteriorated. is there.

  Therefore, as one solution, it is conceivable to attach a roof or gutter to the water heater storage tank 1. However, there are various environments in which the large water heater storage tank 1 is installed, and there is a big problem in attaching roofs and gutters corresponding to the various installation environments.

  Therefore, the inventors pay attention to the fact that the wall surface around the housing of the water heater storage tank 1 is covered with a plurality of side plates 100 for maintenance, and the abutting portions of the two side plates 100 are formed as concave grooves 160. Thus, the groove 160 is used as a passage for guiding rainwater flowing from the top plate 200 to the ground contact surface.

  In this embodiment, as shown in FIG. 2 (b), a concave stepped portion 161 is formed, with the end portions of the side panel panels 101 and 102 that wrap around the front facing one step inward, and a pair of both sides on both sides is formed. The front panel 103 having a smaller width than that between the pair of stepped portions 161 is attached to the stepped portion 161. Four concave grooves 160 can be provided in the front-rear direction.

  In the conventional case structure, when the front panel is attached to the front surfaces of the pair of side plates, the design is generally improved by attaching the members without gaps. However, in this embodiment, the gap between the members is intentionally increased, so that it can be used as a water channel and can be manufactured / assembled without being aware of the fitting accuracy between the members. In this embodiment, the rear panel 104 has the same mounting structure as the front panel 103.

  Further, in this embodiment, a concave passage 201 that guides rainwater to a concave groove 160 formed in the side plate 100 is formed in the top plate. In this embodiment, the concave water channel 203 formed inside the end portion 202 around the top surface of the top plate 200 and the concave water channel 203 communicating with the concave groove portion 160 so as to leave a predetermined edge. The concave passage 201 is formed including the opening passage 204 formed at the position of the concave portion 201.

  In the conventional case structure, in order to maintain the strength of the case, the case provided with a wide steel plate has a structure in which the inner frame is reinforced or the steel plate is provided with an uneven pattern. However, in the case of a top plate, if a concave pattern is applied, rainwater collects, so it is common to apply a convex pattern. In particular, in a case where the top plate has a wide area, dust adhering to the top plate flows to the surrounding side surface by rainwater, thereby causing a streaky raindrop pattern.

  Therefore, in this embodiment, by forming a concave water channel 203 having a V-shaped cross section around the top surface of the top plate 200, rainwater that has fallen on the top plate 200 is formed to collect in this concave water channel 203. Rainwater collected in the concave water channel 203 is formed so as to be guided to the concave groove portion 160 through the opening passage 204.

  As described above, according to this embodiment, the rain water that has fallen on the top plate 200 is guided to the surrounding concave water channel 203 together with the dust adhering to the top plate 200. Then, the rainwater containing dust guided to the concave water channel 203 flows along the concave groove portion 160 via the opening passage 204 and is discharged to the ground surface. On the other hand, although rainwater hits the side plate 100 as well, since this side plate 100 is originally a vertical surface to which dust does not easily adhere, raindrop patterns due to rainwater that has fallen on the side plate 100 hardly occur.

  Therefore, according to this embodiment, the concave groove portion 160 is formed between the pair of side plates by the conventional simple bonding, so that the accuracy of the butting can be kept low and the machining process and the assembly process can be simplified. By providing the plate 200 with the concave passage 201 for guiding rainwater to the concave groove portion 160, the rainwater falling on the top plate 200 is guided to the concave groove portion 160 and discharged to the ground surface while strengthening the strength of the top plate 200. Therefore, the dirt due to rain on the side plates around the top plate 200 can be reduced.

  With reference to FIG. 3 and FIG. 4, a water heater storage tank according to a second embodiment will be described. Here, FIG. 3 is an external view of a water heater storage tank according to the second embodiment, wherein (a) is a plan view, (b) is a front view, (c) is a right side view, (d).

  In FIG. 3, the water heater storage tank 2 according to this embodiment has a height of 2235 mm, a depth of 660 mm, and a width of 540 mm. Also in this embodiment, a concave passage 201 is provided around the upper surface of the top plate 200 to collect rainwater that has fallen on the top plate 200 together with dust in the concave passage 201, and the collected rainwater is provided in the side plate 100. A structure for discharging to the ground contact surface via 160 is provided. The difference from the first embodiment is the specific structure of the top plate 200 and the side plate 100. Hereinafter, the points different from the first embodiment will be mainly described.

  First, the side plate 100 is composed of a front panel 111 composed of three panels arranged with a large roundness on both sides, a side panel 112 formed with a large roundness from the side to the back, and both side plates 112. And a back panel 113 disposed therebetween. In this embodiment, due to the difference in the panel structure, a total of two concave grooves 160 are formed on both sides of the rear panel 113 on the back side. The structure of the groove 160 is the same as that of the first embodiment.

  On the other hand, as shown in FIG. 4, the top plate 200 includes a frame housing 210 whose center is largely opened, and a top panel 212 that closes the large opening 211 of the frame housing 210. The frame assembly 210 is provided with a peripheral frame 213 formed so that the periphery thereof is continuous with the side plate 100, and a concave water channel 214 is formed around the inside thereof. The concave water channel 214 is formed so as to surround the central opening 211. Further, the peripheral frame 213 is formed with a notch 215 that is continuous with the concave groove 160. The notch 215 is formed continuously with the bottom 216 of the concave water channel 214.

  The top panel 212 is a press-molded processing member whose periphery is bent inward, and an edge body 217 bent inward is inserted and attached from above so as to fit into the concave water channel 214. Yes.

  According to this embodiment, the top plate 200 has a combination of a plurality of members, that is, a structure in which the top panel 212 and the peripheral frame 213 are combined. Therefore, the structure of each member can be simplified and downsized. it can.

  With reference to FIG. 5, the water heater storage tank 3 according to the third embodiment will be described in detail. Here, FIG. 5 is a schematic configuration diagram of a water heater tank according to the third embodiment.

  The water heater storage tank 3 of this embodiment has a structure of the side plate 100 similar to that of the second embodiment, and is provided with concave grooves 160 on both sides of the back panel 113. The characteristic point of the third embodiment is that the steel plate constituting the top plate 200 is provided with a concavo-convex shape for guiding rainwater to the concave groove portion 160.

  That is, in the concave passage 201 provided in the top plate 200 of the first and second embodiments, the structure in which the concave water passage 203 and the concave water passage 214 are provided around the upper surface has been described. However, the present invention is limited to this structure. However, the same effect can be obtained if the structure guides rainwater falling on the top plate 200 to the concave groove 160. In the third embodiment, the top panel 220 that is the main body of the top panel 200 has an uneven shape that gradually inclines toward the concave groove 160.

  In this embodiment, since the two concave groove portions 160 are provided on the left and right, the top panel 220 is divided into two left and right between the two concave groove portions 160, and the dividing line portion 221 and its The edge portions 222 on both sides and the front edge portion 223 are set as the most apex portion 224, and the structure is inclined from the most apex portion 224 toward the two valley portions 225 provided with the concave groove portions 160. In this embodiment, the above structure is realized by applying a simple press work to the steel sheet.

  According to this structure, the concave passage 201 that guides rainwater to the concave groove portion 160 can be formed while maintaining the strength by performing a simple press process on the upper surface portion of the top plate 200. In addition, the uneven | corrugated shape of the Example of FIG. 5 is an example, Comprising: It is not limited to this. That is, if this uneven shape is a shape that is inclined from the most apex portion 224 around the top plate 200 toward the valley portion 225 in the vicinity of the concave groove portion 160, the same effect can be obtained.

  Next, the water heater storage tank 4 according to the fourth embodiment will be described in detail with reference to FIG. Here, FIG. 6 is a schematic configuration diagram of a water heater tank according to the fourth embodiment, where (a) is a development view of parts, (b) is a longitudinal sectional view in the vicinity of the top plate, and (c) is a diagram. (B) It is a longitudinal cross-sectional view of the top plate vicinity which shows the other application example of a figure.

  The water heater storage tank 4 of this embodiment also has a structure of the side plate 100 similar to that of the second embodiment, but is not a structure in which concave grooves 160 are positively provided on both sides of the back panel 113. The difference is that a decorative panel 120 having a size covering the back panel 113 is provided with a gap 121 between the back panel 113 and the back panel 113.

  That is, in this embodiment, the top plate 200 is composed of a peripheral frame body 230 formed by standing around the side plate 100 so as to be continuous with the side plate 100, and a top panel panel 231 forming the inside of the peripheral frame body 230. The The upper end portion of the peripheral frame body 230 is formed to be the most apex portion 224 except for the vicinity of the back panel 113. The top panel 231 is formed on an inclined surface that inclines toward the back panel 113 such that the back panel 113 side becomes a valley 225. A notch 232 is formed in the vicinity of the upper portion of the back panel 113 of the peripheral frame 230 so that rainwater flows from the valley 225 to the back panel 113.

  In this embodiment, as shown in FIG. 5B, rainwater that pours onto the top plate 200 is guided to the valley portion 225 along the inclined surface of the top plate panel 231 together with dust adhering to the top plate 200. Since the notch 232 is formed in the valley 225, the rainwater guided to the valley 225 is transmitted to the back panel 113 and discharged to the ground plane. Here, since a gap 121 is formed between the back panel 113 and the decorative panel 120, the decorative panel 120 can prevent rainwater from being transmitted to the other side plates 112. As a result, dirt due to raindrops adheres to the back panel 113, but since this dirt is concealed by the decorative panel 120, it is reduced to impair the design. Moreover, if the decorative panel 120 is structured to be detachable, the cleanability of the back panel 113 to which dirt due to raindrops has adhered can be improved.

  Further, in the embodiment shown in FIG. 5B, the structure for attaching to the decorative panel 120 with the gap 121 has been described. However, as shown in FIG. . In this case, the drainage channel 122 is formed between the back panel 113 and the decorative panel 120 by providing the back panel 113 so as to be recessed one step further. Thereby, the same effect as the gap 121 can be obtained without projecting the decorative panel 120 outward.

  Thus, in this embodiment, rainwater falling on the top plate 200 is applied to one peripheral side surface (rear panel 11) covered with the decorative panel 120 by the peripheral frame body 230, the inclined top plate panel 231 and the notch 232. Can be guided and discharged.
