Description
Technical Field
The invention relates to a heat source machine.
Background
As one type of heat source device, there is a wall-through type burner provided so as to penetrate through an outer wall that separates an indoor space from an outdoor space. In the wall-through type burner, a casing is inserted into a through hole provided in an outer wall, and a combustion unit such as a heat exchanger is housed in the casing.
Such a wall-through burner is disclosed in, for example, japanese patent No. 4167611 and japanese patent No. 4703898. In the wall-through type burners described in these documents, the combustion unit is covered from the indoor side by a front cover. The front cover is fixed to the housing with screws.
Disclosure of Invention
Since the front cover is fixed to the housing by screws, the work of attaching and fixing the front cover is complicated.
The present invention has been made in view of the above problems, and an object thereof is to provide a heat source unit in which a front cover can be easily attached.
A heat source device of the present invention includes a heat exchanger, a casing, and a front cover. The casing houses the heat exchanger therein. The front cover is located in front of the heat exchanger and mounted to the housing. The housing includes a 1 st inclined portion having an inclined portion. The front cover has a guided portion. The guided portion is movable along the inclined portion of the 1 st inclined portion to be guided, and has a portion located rearward of the inclined portion in a state where the front cover is attached to the housing.
According to a heat source machine of the present invention, the guided portion is guided along the inclined portion of the 1 st inclined portion. Therefore, when the guided portion pair is positioned at the 1 st inclined portion, the width of the alignment in the front-rear direction is wide. Therefore, the guided portion can be easily positioned on the 1 st inclined portion, and the attachment work of the front cover to the housing is easy.
In addition, in a state where the front cover is attached to the housing, the portion of the guided portion is located rearward of the inclined portion of the 1 st inclined portion. Therefore, when the guided portion moves forward, the inclined portion of the 1 st inclined portion becomes an obstacle, and therefore, the front cover is less likely to drop off forward from the housing.
In the above-described heat source unit, the portion of the guided portion is located above the 1 st inclined portion. The inclined portion of the 1 st inclined portion is an inclined portion that slopes downward from the front to the rear.
Thereby, the guided portion attempts to move rearward along the inclined portion of the 1 st inclined portion by its own weight. Therefore, the work of attaching the front cover to the housing is facilitated.
In the above-described heat source machine, the casing includes the 2 nd inclined portion having the inclined portion that is inclined upward from the front toward the rear.
This allows the 1 st inclined part and the 2 nd inclined part to have symmetrical shapes.
In the above-described heat source unit, the guided portion has the 3 rd inclined portion and the 4 th inclined portion. The 3 rd inclined part has an inclined part descending from the front to the rear and is movable along the 1 st inclined part. The 4 th inclined part has an inclined portion that slopes upward from the front toward the rear and is opposite to the 2 nd inclined part.
This allows the guided portion to have a symmetrical shape. Therefore, when the combination of the 1 st inclined part and the 2 nd inclined part is provided on the left and right sides, the guided parts having the same shape can be used for both the combination on the left side and the combination on the right side. Therefore, the parts can be made common, and the labor and time for processing the parts can be saved.
Further, when the front cover is shaken with respect to the housing in a state in which the front cover is attached to the housing, shaking of the front cover with respect to the housing can be suppressed by bringing the 3 rd inclined portion into contact with the 1 st inclined portion or bringing the 4 th inclined portion into contact with the 2 nd inclined portion.
In the above-described heat source machine, the case has the mounting piece having the 1 st inclined portion and the 2 nd inclined portion. The mounting piece has a flat portion between an end of the 1 st inclined portion and an end of the 2 nd inclined portion.
Thus, the front cover can be detached from the housing by simply lifting the front cover to a position where the guided portion passes over the flat portion. Therefore, the lifting height of the front cover when the front cover is detached from the housing can be reduced, and the operation of detaching the front cover from the housing is easy.
In the above-described heat source machine, the case has the mounting piece having the 1 st inclined portion and the 2 nd inclined portion. An end of the 1 st inclined part and an end of the 2 nd inclined part are connected to each other.
This makes it possible to increase the length of the 1 st inclined part in the front-rear direction as compared with a structure in which the flat part is provided. Therefore, when the guided portion pair is positioned at the 1 st inclined portion, the width of the front-rear direction alignment is made wider. Therefore, the guided portion can be positioned more easily at the 1 st inclined portion, and the attachment work of the front cover to the housing can be facilitated.
In the above-described heat source machine, the front cover is fixed to the casing by the screw member.
In the state where the front cover is attached to the housing as described above, the guided portion is located behind the inclined portion of the 1 st inclined portion, and the front cover is less likely to drop off forward from the housing. Therefore, the number of screw members for fixing the front cover to the housing can be reduced as compared with the case where the front cover is attached to the housing only by the screw members. This reduces the number of screws to be attached, and reduces the work of screwing the screws, thereby facilitating the work of attaching the front cover to the housing.
In the above-described heat source machine, the front cover has a cover main body portion and a housing portion attached to the cover main body portion. The receiving portion has a guided portion and forms a gap into which the 1 st inclined portion can be inserted between the receiving portion and the cover main body portion.
This makes it possible to easily obtain a structure in which the 1 st inclined part is inserted into the gap between the guided part and the cover main body part.
In the above-described heat source unit, the accommodating portion has an end portion constituting an inlet of the gap, and is bent so as to be apart from the cover main body portion as going toward the end portion.
This makes it easy to insert the 1 st inclined part into the gap between the housing part and the cover main body part, and the attachment work of the front cover to the housing is made easier.
In the above-described heat source machine, the accommodating portion includes the mounting portion and the guided portion. The mounting portion is mounted to the cover main body portion. The guided portion is connected to the mounting portion and forms a gap with the cover main body portion. The guided portion has a notch extending from an end of the guided portion to the mounting portion.
Since the notch is formed, the guided portion bent from the mounting portion can be formed by bending 1 sheet of the plate material, not by deep drawing. Therefore, the guided portion can be easily processed.
In the above-described heat source machine, the accommodating portion includes the mounting portion and the guided portion. The mounting portion is mounted to the cover main body portion. The guided portion is connected to the mounting portion and forms a gap with the cover main body portion. The guided portion does not have a notch extending from an end of the guided portion to the mounting portion.
Since no notch is formed in this way, the strength of the guided portion can be improved.
Another heat source device of the present invention includes a heat exchanger, a casing, and a front cover. The casing houses the heat exchanger therein. The front cover is located in front of the heat exchanger and mounted to the housing. The housing has a mounting tab. The front cover includes an inclined portion. The inclined portion is guided so as to be movable along the attachment piece, and has an inclined portion located behind the attachment piece in a state where the front cover is attached to the housing.
According to another heat source unit of the present invention, the inclined portion is guided along the mounting piece. Therefore, when the inclined portion is aligned with the mounting piece, the width of the alignment in the front-rear direction is wide. Therefore, the inclined portion is easily positioned on the mounting piece, and the mounting work of the front cover to the housing is easy.
In addition, the inclined portion has an inclined portion located rearward of the attachment piece in a state where the front cover is attached to the housing. Therefore, the mounting piece is an obstacle when the inclined portion of the inclined portion moves forward, and the front cover is not easily detached forward of the housing.
The foregoing and other objects, features, aspects and advantages of the present invention will become apparent from the following detailed description of the present invention, which is to be read in connection with the accompanying drawings.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
In the description and the drawings, the same components or corresponding components are denoted by the same reference numerals, and repetitive description thereof will not be repeated. In the drawings, the structure may be omitted or simplified for convenience of explanation. At least some of the embodiments and modifications may be combined with each other arbitrarily.
< Structure of heat source machine >
First, as an example of the heat source unit according to the embodiment of the present invention, a structure of the wall-through type burner will be described with reference to fig. 1.
However, the heat source unit is not limited to the burner, and may be, for example, a hot water supply device, a heating device, a hot water supply device for hot water bath with hot water heating, or the like. The heat source unit may be a system that burns fuel gas or a system that burns petroleum. The heat source unit may be of a hot water storage type or of an immediate type. The heat source machine is not limited to a push-and-burn (japanese: push し - し -fire-sintered) hot water supply device, but may be an exhaust-suction-and-combustion (japanese: exhaust-suction-and-fire-sintered) hot water supply device.
As shown in fig. 1, the wall-through burner 10 of the present embodiment is inserted into a through hole 30a provided in an outer wall 30, and the outer wall 30 partitions the interior and exterior of a room. The wall-through burner 10 mainly includes a front cover 1, a casing 2, a blower 3, a combustion device 4, a heat exchanger 5, and a pipe 6.
The housing 2 is disposed to penetrate through the through hole 30a of the outer wall 30. The front end 2F of the housing 2 protrudes from the outer wall 30 toward the inside. The rear end 2R of the housing 2 protrudes from the outer wall 30 to the outside.
The blower 3, the combustion device 4, and the heat exchanger 5 are all housed inside the casing 2. The blower 3, the combustion device 4, and the heat exchanger 5 are arranged in this order from the indoor side to the outdoor side.
The blower 3 is for introducing air from the outside of the casing 2 and supplying the air to the combustion device 4. A combustion device 4 is connected to the outdoor side of the blower 3.
The combustion apparatus 4 is configured to generate combustion gas as heating gas by combusting a mixed gas of fuel gas and air. A heat exchanger 5 is connected to the outdoor side of the combustion device 4.
The heat exchanger 5 is used to exchange heat between the combustion gas generated by the combustion device 4 and water inside the heat exchanger 5. The heat exchanger 5 has, for example, 1 heat exchanger and 2 heat exchangers. The 1 st-order heat exchanger is a sensible heat recovery type heat exchanger for recovering sensible heat of the combustion gas generated in the combustion apparatus 4. The 2-time heat exchanger is a latent heat recovery type heat exchanger for recovering latent heat of the combustion gas generated in the combustion device 4.
In order to discharge the combustion gas having exchanged heat with the heat exchanger 5 to the outside of the casing 2, a plurality of exhaust holes (not shown) are provided in a portion of the casing 2 protruding from the outer wall 30 to the outside.
The pipe 6 is connected to the heat exchanger 5. The pipe 6 is a water supply pipe or a hot water discharge pipe.

The pipe cover portion TC covers the front and left and right sides of the pipe 6 extending downward from the internal space 2ba of the housing 2 to the outside as shown in fig. 1.
< Structure of mounting piece and receiving part >
Next, the structure of the mounting piece 2e and the housing portion 1b of the wall-through burner 10 of the present embodiment will be described with reference to fig. 3 and 4.
As shown in fig. 3, when the front cover 1 is attached to the housing 2, first, the front cover 1 is moved rearward so as to approach the front end 2F of the housing 2 from the front of the housing 2. This movement positions the accommodating portion 1b directly above the mounting piece 2 e. Thereafter, the front cover 1 is moved downward with respect to the housing 2. By this movement, the accommodating portion 1b is inserted into the gap between the mounting piece 2e and the side plate 1 as.
As shown in fig. 4, the mounting piece 2e has, for example, a trapezoidal shape in a side view as viewed from the left-right direction. The mounting piece 2e of the housing 2 has a 1 st inclined portion 2ea, a 2 nd inclined portion 2eb, and a flat portion 2 ec. The 1 st inclined portion 2ea has an inclined portion that slopes downward from the front to the rear.
The 2 nd inclined portion 2eb is located forward of the 1 st inclined portion 2 ea. The 2 nd inclined portion 2eb has an inclined portion that slopes upward from the front toward the rear. The 1 st inclined portion 2ea and the 2 nd inclined portion 2eb are inclined so that a distance LA in the front-rear direction between the 1 st inclined portion 2ea and the 2 nd inclined portion 2eb becomes larger as going from the upper side to the lower side.
The flat portion 2ec connects the upper end of the 1 st inclined portion 2ea with the upper end of the 2 nd inclined portion 2 eb. The front and rear ends of the flat portion 2ec have the same height, and the front and rear ends of the flat portion 2ec are flat therebetween. The mounting piece 2e is connected to the support portion 2da at the lower end of the 1 st inclined portion 2ea and the lower end of the 2 nd inclined portion 2 eb.
The mounting piece 2e has a shape axisymmetrical with respect to the imaginary line C in side view. The virtual line C is a line that is orthogonal to the flat portion 2ec and passes through the center of the flat portion 2 ec. The inclination angle of the 1 st inclined part 2ea with respect to the flat part 2ec and the inclination angle of the 2 nd inclined part 2eb with respect to the flat part 2ec are the same as each other. The inclination angle θ 1 of the 1 st inclined portion 2ea and the inclination angle θ 2 of the 2 nd inclined portion 2eb are both 45 degrees or more. This can suppress frictional resistance when the guided portion 1bb is guided by the 1 st inclined portion 2 ea.
The housing portion 1b of the front cover 1 has a mounting portion 1ba and a guided portion 1 bb. The mounting portion 1ba and the guided portion 1bb are formed of 1 plate, constituting an integrated object. The mounting portion 1ba is a flat plate-like portion and is a portion mounted to the cover main body portion 1a of the front cover 1.
The guided portion 1bb is connected to the mounting portion 1 ba. A gap is formed between the guided portion 1bb and the cover main body portion 1 a. Specifically, the guided portion 1bb is bent with respect to the mounting portion 1ba so as to form a gap with the side plate 1as of the cover main body portion 1 a.
The guided portion 1bb is a portion that is guided while moving along the 1 st inclined portion 2ea of the attachment piece 2e when the front cover 1 is attached to the housing 2. The guided portion 1bb has a 3 rd inclined portion 1bc and a 4 th inclined portion 1 bd.
The 3 rd inclined portion 1bc has an inclined portion that descends from the front toward the rear. The 3 rd inclined part 1bc is a part moving along the 1 st inclined part 2 ea. The 4 th inclined portion 1bd has an inclined portion that slopes upward from the front to the rear. The 4 th inclined portion 1bd is a portion opposed to the 2 nd inclined portion 2 eb.
The 3 rd inclined part 1bc and the 4 th inclined part 1bd are inclined so that a distance LB in the front-rear direction between the 3 rd inclined part 1bc and the 4 th inclined part 1bd becomes larger as going from the upper side to the lower side.
The guided portion 1bb has a shape axisymmetric with respect to the imaginary line C in side view. The inclination angle of the 3 rd inclined portion 1bc with respect to the front-rear direction and the inclination angle of the 4 th inclined portion 1bd with respect to the front-rear direction are the same as each other.
The guided portion 1bb has a notch 1 be. The notch 1be extends from the tip (lower end) of the guided portion 1bb to the mounting portion 1 ba. The guided portion 1bb is divided into two parts by the notch 1 be. The rear portion of the two divided portions of the guided portion 1bb has a 3 rd inclined portion 1 bc. The front portion of the two divided portions of the guided portion 1bb has a 4 th inclined portion 1 bd. The rear portion and the front portion of the two divided portions of the guided portion 1bb have shapes axisymmetric to each other with respect to the imaginary line C.
As shown in fig. 5 and 6, in a state where the front cover 1 is attached to the housing 2, the attachment piece 2e is inserted into a gap between the guided portion 1bb and the side plate 1 as. That is, in a state where the front cover 1 is attached to the housing 2, the 1 st inclined portion 2ea and the 2 nd inclined portion 2eb are each inserted into the gap between the accommodating portion 1b and the cover main body portion 1 a.
As shown in fig. 5, in a state where the front cover 1 is attached to the housing 2, a part of the guided portion 1bb is positioned behind the 1 st inclined portion 2 ea. Specifically, in a state where the front cover 1 is attached to the housing 2, the 3 rd inclined portion 1bc of the guided portion 1bb is located behind the 1 st inclined portion 2 ea. In this state, the 4 th inclined portion 1bd of the guided portion 1bb is positioned in front of the 2 nd inclined portion 2 eb.
In a state where the front cover 1 is attached to the housing 2, a part of the guided portion 1bb is positioned above the 1 st inclined portion 2 ea. Specifically, in a state where the front cover 1 is attached to the housing 2, the 3 rd inclined portion 1bc of the guided portion 1bb is positioned above the 1 st inclined portion 2 ea. In this state, the 4 th inclined part 1bd of the guided part 1bb is positioned above the 2 nd inclined part 2 eb.
As shown in fig. 6, the guided portion 1bb of the accommodating portion 1b has an end portion 1bt (lower end portion). The end portion 1bt constitutes an entrance of a gap between the accommodating portion 1b and the cover main body portion 1 a. Here, the entrance of the gap refers to an entrance for inserting the attachment piece 2e into the gap between the housing portion 1b and the cover main body portion 1 a. The guided portion 1bb of the accommodating portion 1b is bent so as to be away from the side plate 1as of the cover main body portion 1a from above toward the end portion 1bt (toward the entrance of the gap) which is the lower end portion. Thus, the distance LC in the left-right direction between the guided portion 1bb of the accommodating portion 1b and the side plate 1as of the cover main body portion 1a increases from above toward the end portion 1bt as the lower end portion.
Mounting method for mounting front cover on housing
Next, a method of attaching the front cover 1 to the housing 2 in the present embodiment will be described with reference to fig. 7 (a) to 7 (C).
As shown in fig. 7 (a), when the front cover 1 is attached to the housing 2, first, the front cover 1 is moved rearward as indicated by an arrow AR1 from the front of the housing 2 to the front end of the housing 2.
As shown in fig. 7 (B), the accommodating portion 1B is positioned directly above the mounting piece 2e by the above-described rearward movement of the front cover 1. Thereafter, the front cover 1 is moved downward in the figure indicated by an arrow AR2 with respect to the housing 2.
The 3 rd inclined portion 1bc of the housing portion 1b is brought into contact with the 1 st inclined portion 2ea of the mounting piece 2e by the above-described downward movement of the front cover 1. Thereafter, the 3 rd inclined part 1bc is moved backward along the 1 st inclined part 2ea, thereby guiding the front cover 1 with respect to the housing 2 rearward as indicated by an arrow AR1 and downward as indicated by an arrow AR 2.
As shown in fig. 7 (C), the front cover 1 is attached to the housing 2 by the above-described rearward and downward movement of the front cover 1. In this state, as shown in fig. 5, the attachment piece 2e is inserted into the gap between the accommodating portion 1b and the side plate 1as of the cover main body portion 1 a.
Thereafter, as shown in fig. 1 and 2, the screw 12 is inserted through the through hole 1ah of the front cover 1 and then screwed into the screw hole 2bh of the housing 2. Thereby fixing the front cover 1 to the housing 2.
< modification example >
Next, a modified example of the heat source unit of the present embodiment will be described.
In the above embodiment, the case where the mounting piece 2e has a trapezoidal shape in side view was described, but the mounting piece 2e may have a triangular shape in side view as shown by the solid line and the broken line in fig. 8. In this case, the upper end of the 1 st inclined portion 2ea and the upper end of the 2 nd inclined portion 2eb are connected to each other.
In addition, although the case where guided portion 1bb has notch 1be as shown in fig. 3 has been described above, guided portion 1bb may not have notch 1be extending from the lower end of guided portion 1bb to attachment portion 1ba as shown in fig. 9. In this case, the portion of the guided portion 1bb having the 3 rd inclined portion 1bc and the portion having the 4 th inclined portion 1bd are not divided but integrally configured.
In the above description, the structure in which the mounting piece 2e of the housing 2 has the 1 st inclined part 2ea and the 2 nd inclined part 2eb and the guided part 1bb has the 3 rd inclined part 1bc and the 4 th inclined part 1bd has been described, but the present invention is not limited to this structure. The present invention may be configured such that the housing 2 has the 1 st inclined portion 2ea, the front cover 1 has the guided portion 1bb, and the guided portion 1bb is movable and guided along an inclined portion of the 1 st inclined portion 2ea and is located rearward of the inclined portion in a state where the front cover 1 is attached to the housing 2. Examples of this configuration will be described below as a 1 st modification and a 2 nd modification.
As in modification 1 shown in fig. 10 (a), the housing 2 may have only the 1 st inclined part 2ea and no 2 nd inclined part. In addition, the housing portion 1b (guided portion 1bb) may not have both the 3 rd inclined portion and the 4 th inclined portion.
As shown in fig. 10B and 10C, in the configuration of the modification 1, the accommodating portion 1B (guided portion 1bb) is guided so as to move along the inclined portion of the 1 st inclined portion 2ea of the housing 2, and is located rearward of the inclined portion in the state where the front cover 1 is attached to the housing 2.
As in the 2 nd modification shown in fig. 11 (a), the housing 2 may have only the 1 st inclined part 2ea and no 2 nd inclined part. In addition, the accommodating portion 1b (guided portion 1bb) may have only the 3 rd inclined portion 1bc and no 4 th inclined portion.
As shown in fig. 11B and 11C, in the configuration of the 2 nd modification example, the 3 rd inclined portion 1bc of the accommodating portion 1B (guided portion 1bb) is guided by moving along the inclined portion of the 1 st inclined portion 2ea of the housing 2 and is located rearward of the inclined portion in the state where the front cover 1 is attached to the housing 2.
In addition, although the configuration in which the mounting piece 2e of the case 2 has the inclined portion has been described in both the 1 st modification and the 2 nd modification in the above embodiment, the mounting piece 2e may not have the inclined portion and the accommodating portion 1b (guided portion 1bb) of the front cover 1 may have the inclined portion 1bc as in the 3 rd modification shown in fig. 12 a.
As shown in fig. 12B and 12C, in the configuration of the modification 3, the inclined portion 1bc of the accommodating portion 1B (guided portion 1bb) is guided by moving along the attachment piece 2e of the housing 2 and is positioned behind the attachment piece 2e in a state where the front cover 1 is attached to the housing 2.
In the above-described embodiment and 1 st to 3 rd modifications, the case where the front cover 1 is attached to the housing 2 by moving it rearward toward the housing 2 and then downward has been described, but the present invention is not limited to this. In the present invention, the structure of the accommodating portion 1b (guided portion 1bb) and the attachment piece 2e in the above-described embodiment and the 1 st to 3 rd modifications may be reversed upside down, and then the front cover 1 may be moved rearward toward the housing 2 and then moved upward to be attached to the housing 2.
< Effect of the present embodiment >
Next, the effects of the present embodiment will be described.
According to the present embodiment, as shown in fig. 7 (a) to 7 (C), the guided portion 1bb is guided along the inclined portion of the 1 st inclined portion 2 ea. Therefore, when the guided portion 1bb is aligned with the 1 st inclined portion 2ea, the width of the alignment in the front-rear direction is wide. That is, as shown in fig. 13, a portion of the guided portion 1bb which is in contact with the 1 st inclined portion 2ea (for example, the 3 rd inclined portion 1bc) may be located within a range of the length L1 in the front-rear direction of the 1 st inclined portion 2 ea. Therefore, the guided portion 1bb is easily positioned on the 1 st inclined portion 2ea, and the operation of attaching the front cover 1 to the housing 2 is easy.
As shown in fig. 5 and 7 (C), in a state where the front cover 1 is attached to the housing 2, the guided portion 1bb is located behind the inclined portion of the 1 st inclined portion 2 ea. For example, the 3 rd inclined part 1bc of the guided part 1bb is located rearward of the inclined part of the 1 st inclined part 2 ea. Thus, when the guided portion 1bb moves forward, the inclined portion of the 1 st inclined portion 2ea becomes an obstacle, and the front cover 1 is less likely to fall off forward from the housing 2.
In the present embodiment, as shown in fig. 5 and fig. 7 (C), when the front cover 1 is attached to the housing 2, the guided portion 1bb is positioned above the 1 st inclined portion 2 ea. The inclined portion of the 1 st inclined portion 2ea is an inclined portion that slopes downward from the front to the rear. Thereby, the guided portion 1bb tries to move rearward along the inclined portion of the 1 st inclined portion 2ea by its own weight. The work of attaching the front cover 1 to the housing 2 is easier.
In the present embodiment, as shown in fig. 4, the housing 2 includes a 2 nd inclined portion 2eb having an inclined portion that inclines upward from the front toward the rear in the 2 nd inclined portion 2 eb. This makes it possible to make the 1 st inclined part 2ea and the 2 nd inclined part 2eb symmetrical, which makes the design easier.
In the present embodiment, as shown in fig. 7 (a) to 7 (C), the guided portion 1bb includes the 3 rd inclined portion 1bc and the 4 th inclined portion 1 bd. The 3 rd inclined portion 1bc has an inclined portion that descends from the front toward the rear and moves along the 1 st inclined portion 2 ea. The 4 th inclined portion 1bd has an inclined portion that slopes upward from the front toward the rear and is opposed to the 2 nd inclined portion 2 eb. This allows the guided portion 1bb to have a symmetrical shape. Therefore, when the mounting pieces 2e including the combination of the 1 st inclined portion 2ea and the 2 nd inclined portion 2eb are provided on the left and right sides as shown in fig. 2, the guided portions 1bb having the same shape can be used for both the left mounting piece 2e and the right mounting piece 2 e. Therefore, the parts can be used in common, and the labor and time for processing the parts can be saved.
Further, as shown in fig. 7 (C), when the front cover 1 is attached to the housing 2 and the front cover 1 is shaken in the direction of the arrow AR3 with respect to the housing 2, the shaking of the front cover 1 can be suppressed by bringing the 3 rd inclined portion 1bc into contact with the 1 st inclined portion 2ea or bringing the 4 th inclined portion 1bd into contact with the 2 nd inclined portion 2 eb.
In the present embodiment, as shown in fig. 8, the housing 2 has a mounting piece 2e, and the mounting piece 2e has a 1 st inclined portion 2ea and a 2 nd inclined portion 2 eb. The mounting piece 2e has a flat portion 2ec between the end of the 1 st inclined portion 2ea and the end of the 2 nd inclined portion 2 eb. Thus, front cover 1 can be detached from housing 2 by simply lifting front cover 1 to a position where guided portion 1bb crosses height H1 of flat portion 2 ec. Therefore, the height of the front cover 1 raised when the front cover 1 is removed from the housing 2 can be reduced, and the operation of removing the front cover 1 from the housing 2 is easy.
In the present embodiment, as shown in fig. 8, the end of the 1 st inclined portion 2ea and the end of the 2 nd inclined portion 2eb may be connected to each other. Thus, the length L2 in the front-rear direction of the 1 st inclined part 2ea can be made larger than the length L1 in the front-rear direction in the case where the flat part 2ec is provided. Therefore, when the guided portion 1bb is aligned with the 1 st inclined portion 2ea, the width of the alignment in the front-rear direction is wider. Therefore, the guided portion 1bb can be positioned more easily on the 1 st inclined portion 2ea, and the operation of attaching the front cover 1 to the housing 2 can be facilitated.
In the present embodiment, as shown in fig. 5 and fig. 7 (C), in a state where the front cover 1 is attached to the housing 2, the guided portion 1bb is positioned behind the inclined portion of the 1 st inclined portion 2ea, and the front cover 1 is less likely to fall off forward from the housing 2. Therefore, the number of screws 12 (fig. 1 and 2) for fixing the front cover 1 to the housing 2 can be reduced as compared with the number of screws 12 in the case where the front cover 1 is attached to the housing 2 only with the screws 12. This reduces the number of screws 12 to be attached, and thus reduces the work of screwing the screws 12, and facilitates the attachment of the front cover 1 to the housing 2.
In addition, in the present embodiment, as shown in fig. 6, the front cover 1 has a cover main body portion 1a and a housing portion 1b attached to the cover main body portion 1 a. The accommodating portion 1b has a guided portion 1bb and forms a gap between itself and the cover main body portion 1a into which the 1 st inclined portion 2ea can be inserted. This makes it possible to easily obtain a structure in which the 1 st inclined part 2ea (fig. 5) is inserted into the gap between the guided part 1bb and the cover main body part 1 a.
In the present embodiment, as shown in fig. 6, the accommodating portion 1b has an end portion 1bt constituting an entrance of the gap and is bent so as to be separated from the cover main body portion 1a toward the end portion 1 bt. This makes it easy to insert the 1 st inclined part 2ea into the gap between the housing part 1b and the cover main body part 1a, and facilitates the attachment work of the front cover 1 to the housing 2.
In the present embodiment, as shown in fig. 4, the guided portion 1bb has a notch 1be extending from the end portion 1bt of the guided portion 1bb to the mounting portion 1 ba. Since the notch 1be is formed, the guided portion 1bb bent from the mounting portion 1ba can be formed by bending 1 sheet of material, not by deep drawing. Therefore, the guided portion 1bb can be easily processed.
In the present embodiment, as shown in fig. 9, the guided portion 1bb does not have a notch extending from the end portion 1bt of the guided portion 1bb to the mounting portion 1 ba. Since no notch is formed in this way, the strength of the guided portion 1bb can be increased.
In addition, in modification 3 shown in fig. 12, the front cover 1 includes an inclined portion 1 bc. The inclined portion 1bc is movably guided along the attachment piece 2e, and has an inclined portion located behind the attachment piece 2e in a state where the front cover 1 is attached to the housing 2. In this manner, in modification 3, the inclined portion 1bc is guided along the mounting piece 2 e. Therefore, when the inclined portion 1bc is positioned on the mounting piece 2e, the width of the positioning in the front-rear direction is wide. Therefore, the inclined portion 1bc is easily positioned on the mounting piece 2e, and the mounting work of the front cover 1 to the housing 2 is easy.
In addition, in a state where the front cover 1 is attached to the housing 2, the inclined portion 1bc has an inclined portion located behind the attachment piece 2 e. Accordingly, the attachment piece 2e becomes an obstacle when the inclined portion of the inclined portion 1bc moves forward, and thus the front cover 1 is less likely to fall forward of the housing 2.
The embodiments of the present invention have been described, but the embodiments disclosed herein are to be considered in all respects as illustrative and not restrictive.
