Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery case which is attached to a device such as a gas stove using a battery as an operating power source. 2. Description of the Related Art It is necessary to attach a battery case for accommodating a battery to an apparatus using a battery as an operation power source. For example, a gas stove, which is a device, has a case body that can move forward and backward with respect to the gas stove while holding a battery. The case body holds a plurality of batteries serving as a power source of the device in a state of being arranged in series, and urges the batteries from one end to the other end of the arranged batteries so that the batteries come into contact with each other. A biasing means such as a spring is provided. In addition, the battery may be lifted from the bottom surface of the case body due to the biasing force of the biasing means, resulting in poor connection. Therefore, the case body is covered from above while the case body is stored in the device body, and the battery is A case cover with a ceiling surface that restricts the device from rising from the ceiling is attached to the main body of the device. In the above-mentioned conventional battery case, since the ceiling surface is formed on the case cover, the case main body is stored in the main body of the device and the case main body is covered with the case cover. Although the battery does not rise from the bottom of the case body, the battery rises from the bottom of the case body while pulling out the case body by replacing the battery, pushing the case body again with the battery inserted in the case body, and storing it Then, the raised battery collides with the front end of the ceiling surface of the case cover, and the case body cannot be pushed further. In particular, when the end of the ceiling surface is in a position recessed in the body of the device, even if the case body is pushed in while holding the battery by hand, the hand holding the battery must be released during the pushing,
If the battery rises from the bottom of the case body after releasing the hand, the battery hits the above-mentioned end of the ceiling surface. [0004] In view of the above problems, the present invention is intended to prevent the battery from hitting the front end of the ceiling even when the battery is raised from the bottom of the case main body when the case main body is stored in the main body of the device. It is an object to provide a battery case that does not have any battery. [0005] In order to solve the above-mentioned problems, the present invention is to hold a plurality of batteries, which are power sources of equipment, in a state of being arranged in series, and to provide one end of the batteries which are arranged in a row. A biasing means for biasing the battery from the other end to the other end, and a case body which can be freely inserted and removed in the direction in which the batteries are arranged, and a case body which is attached to the body of the device and which is stored in the body of the device. And a case cover having a ceiling surface that regulates the lifting of the battery from the bottom surface of the case body with respect to the battery. When the case body is stored in a state where it floats from the bottom of the body,
The battery is characterized in that an inclined surface is formed to push down the battery to the bottom side of the case body. Even if the battery rises from the bottom of the case body while the battery case is being pushed in, the floated battery comes into contact with the inclined surface and is pushed down by the inclined surface as the battery case is pushed in. Referring to FIG. 1, reference numeral 1 denotes a gas stove, which is a device using a battery as an operating power source. An opening 12 is formed in a front panel 11 of the gas stove 1, and a case main body 2 of a battery case for housing a battery is stored through the opening 12. The gas stove 1 is provided with a temperature sensor 13 for detecting a pan bottom temperature and a thermocouple 14 for detecting ignition and misfire.
And a control device (not shown) for controlling the open / close state of an electromagnetic safety valve (not shown) based on a detection signal from the controller. The control device and the ignition device (not shown) operate using a battery housed in the case body 2 as a power supply. Referring to FIGS. 2 and 3, the battery case is provided with a case plate 3 attached to the main body of the gas stove 1 in addition to the case main body 2, and is engaged with the case plate 3 from above. And a case cover 4 that covers the main body 2 from above and restricts movement of the case main body 2 in the left-right direction and prevents the battery from floating from the case main body 2. The front end of the case body 2 has the opening 1
A cover plate 21 for closing the cover 2 is integrally attached. A window hole 21a is formed in the upper part of the cover plate 21, and the lever piece 22 is moved from the rear to the front through the window hole 21a.
Is protruding. The lever piece 22 is connected to a lock piece 23. The lock piece 23 is formed so as to be capable of elastically swinging up and down around a position spaced a predetermined distance rearward from the lock piece 23. Therefore, when the case body 2 is further pushed in from the state shown in FIG. 3, the lock pieces 23 ride on the front edge of the case plate 3 and then enter the lock holes 31 formed in the case plate 3. Then, the lock piece 23 engages with the front edge of the lock hole 31 so that the case body 2 cannot be pulled out forward. When the lever piece 22 is pulled up in this state, the lock piece 23 connected to the lever piece 22 is simultaneously pulled up and comes off the lock window 31. Then, the lock piece 23 does not engage with the lock hole 31 and the case body 2 can be pulled out forward as it is. On the bottom surface of the case body 2, there is formed a slope 24 which is inclined inward from left and right inward with respect to the insertion and removal direction of the case body 2. And left and right slope 2
4, a plurality of drain holes 25 penetrating through the bottom surface of the case main body 2 are formed in the water collecting portion 24 a, which is the lowest part of the bottom surface of the case main body 2. The water collecting part 2
4a is inclined downward in the front-rear direction toward the drain hole 25, and the water collected at the center along the left and right slopes 24 is further divided in the front-rear direction and collected in the drain hole 25. On the upper surface of the case plate 3, a longitudinal groove 33 is formed in a longitudinal direction so as to be located below each of the drain holes 25. The concave groove 33 is formed so that the depth increases from the rear end side to the front end side, and the opening 32 is formed in the front end portion.
Is formed. Therefore, even if a liquid such as water enters the case body 2, the case body 2 passes through the drain hole 25.
And is not accumulated in the case main body 2. The liquid discharged from the drain hole 25 is collected in the concave groove 33 and drained from the opening 32. By the way, the position of the water collecting portion 24a is determined by the electrodes 26a and 26b, the extraction electrode 26c,
It is set at a position lower than the position of any lower edge of the connection portion 26d, and no electric leakage occurs between the electrodes 26a and 26b via water etc. even before water etc. is discharged from the drain hole 25. . A pair of electrodes 26a and 26b facing each other are attached to the case body 2. Further, a metal spring 27 as an urging means is attached to the rear electrode 26b, and the two batteries are connected in series to the case body 2
When the battery is stored in the electrode 2, as shown in FIG.
6a. An extraction electrode 26c was attached at a predetermined interval beside the rear electrode 26b. And
The electrode 26a and the extraction electrode 26c were electrically connected via the connection part 26d. Note that the electrode 26a, the extraction electrode 26c, and the connection portion 26d are integrally formed. Referring to FIG. 5, a pair of front and rear engagement hooks 41 project from the bottom left side of case cover 4, and the engagement hooks 41 are positioned above window holes 34 formed in case plate 3. Inserted from. Then, the case cover 4 is in a state where it can rotate clockwise as viewed from the front centering on the engagement portion between the engagement hook 41 and the window hole 34. On the other hand, a pair of front and rear projections 42 is provided on the right bottom of the case cover 4. Similarly, a pair of front and rear claws 43 is formed on the outer side surface of the right bottom side so as to be elastically deformable outward. On the other hand, the case plate 3 has a window hole 35 into which the projection 42 is inserted and a notch 36 into which the claw 43 is inserted. Therefore, the case cover 4 is
When the rotation is made about the engagement portion between the hole and the window hole 34, the projection 42 is first inserted into the window hole 35, and then the claw 43 enters the notch 36, and the claw 43 is a locking portion. Case plate 3
Engages the lower surface of. Then, the case cover 4 is firmly engaged with the case plate 3 and does not come off. However, when the right side wall of the case cover 4 is pushed outward, the claw 43 moves outward because the claw 43 is integrally formed on the right side wall, and the engagement of the claw 43 with the case plate 3 is released. There is a risk. For example, when the case main body 2 is pushed to the right while the case main body 2 is inserted approximately half into the case cover 4, the case main body 2 is pushed rightward to the right wall of the case cover 4 via the case main body 2. Force acts. However, in the present embodiment, since the projection 42 is inserted into the window hole 35, the projection 42 is engaged with the window hole 35 even when a force is applied to push the right side wall toward the right side. The right side wall does not move outward. Therefore, the claw 43 is artificially
The claw 43 does not come off the case plate 3 unless the work is taken off the case plate 3. However, the claw 43 is shown in FIG.
Also, as shown in FIG. 5, the base of the claw 43 is formed by applying a force acting outward from the lower side of the case plate 3 to the tip of the claw 43 since the case cover 4 is formed in a leg shape from the side surface. And the claw 43 can be removed from the case plate 3. [0013] Flanges 28 are formed on both sides of the case body 2. A guide portion 44 is formed on the inner peripheral surface of the case cover 4 so as to face the flange portion 28 from the left and right sides and from above with a small gap. Therefore, when the case body 2 is taken in and out, the case body 2 slides on the case plate 3 in a state where the movement in the left-right direction and the up-down direction is restricted by the guide portion 44. Since the battery in the case body 2 is biased by the spring 27, if the biasing force of the spring 27 acts obliquely on the battery, there is a possibility that the battery will float upwardly, which allows only movement. Therefore, the inner peripheral surface of the case cover 4 is formed in a cylindrical shape in conformity with the shape of the battery, and the portion located above the battery is a ceiling surface 48. Even if the battery is going to float, the ceiling surface 48 Is trying to suppress the lifting of the battery. On the other hand, it is necessary to connect the electric wire 5 for supplying power to a control device (not shown) to the electrode 26b and the extraction electrode 26c. In order to connect the electric wire 5, it is necessary to provide a longitudinal slit-shaped opening in the direction of movement of the case body. However, when the opening is formed on the center line of the case cover 4, when the battery rises from the case main body, the most effective part of the ceiling surface that prevents the battery from lifting up is removed because of the slit-shaped opening. Will be. Therefore, in the present embodiment, the slit opening 45 is opened at a position shifted rightward from the center line of the case cover 4. The slit opening 4 is shifted to the right side as described above.
5, the extraction electrode 26c was attached so as to be located on the right side of the electrode 26b. However, the slit opening 45 may be provided so as to be shifted to the left side.
6c is attached so as to be located on the left side of the electrode 26b. A push claw 46 which is elastically deformable in the front-rear direction is formed on the inner wall of the case cover 4. When the case body 2 is pushed into the gas stove 1 and retracted, the lock pieces 23 enter and engage with the lock holes 31 as described above, but the case body 2 rattles as it is. Therefore, the rear end face of the case body 2 is urged toward the front by the push claws 46 so that the lock pieces 23 are pressed against the front edge of the lock holes 31 to prevent rattling. As described above, the cover plate 21 is provided with the window hole 21a through which the lever piece 22 is inserted. It is conceivable that water or the like may splash on the front surface of the gas stove 1. At this time, if water or the like enters the inside of the battery case through the window hole 21a, it may cause a short circuit or the like, which is not desirable. In view of this, a fixing plate 47 covering the entire width in the left-right direction is provided in the upper part of the mouth of the case cover 4 in a hanging manner, and a protection plate 29 covering the entire width in the left-right direction is also provided on the case body 2. When the case body 2 is pushed into the storage position, the fixing plate 4
The protection plate 29 is formed so as to lightly contact the front surface of the nozzle 7 or to face it with a small gap. With this configuration, even if water or the like enters through the window hole 21a, the protection plate 29 prevents the water or the like from entering any further. Further, even if water or the like tries to pass over the protection plate 29, the permeation of water or the like is prevented by the fixing plate 47. The ceiling surface 48 of the case cover 4 is close to the battery and prevents the battery from floating as described above. However, when the case body 2 is pulled out and the case body 2 is returned to the gas stove 1 with the new battery set in the case body 2 and the batteries are already slightly lifted up, the battery is attached to the front end of the ceiling surface 48. The battery case 2 may not be pushed further. Therefore, as shown in FIG. 3, a tapered inclined surface 48a is formed at the front end of the ceiling surface 48. Thus, even if the battery is slightly lifted and the case body 2 is to be returned into the gas stove 1, the battery is not caught by any part of the case cover 4 and is pushed down by the inclined surface 48 a while being pressed down by the inclined surface 48 a. It is possible to proceed to the back of the cover 4. Incidentally, a rib 45a is provided upright on one side edge of the slit opening 45. In the above embodiment, since the ribs 45a are formed to increase the mechanical strength of the case cover 4, the height of the ribs 45a may be several mm. On the other hand, if the connector 51 for connecting the electric wire 5 to the electrode 26a and the extraction electrode 26c projects above the rib 45a, the connector 51
Moves while projecting above the rib 45a,
There is a possibility that the connector 51 may catch other wires and harnesses. Therefore, as shown in FIG. 6, it is desirable that the height of the rib 45a be about 20 mm so that the connector 51 is hidden by the rib 45a. In addition, even if the case main body 2 is put in and out while the electric wire 5 connected to the connector 51 protrudes from the rib 45a, the electric wire 5 is easily bent, so that there is no problem that the electric wire 5 is hooked on another electric wire or harness. By the way, when the case main body 2 is constructed so that it can be completely removed from the gas stove 1 when the case main body 2 is pulled out forward, the electric wire 5 is pulled and the electric wire 5 is disconnected or the contact at the connector 51 is made. Failure may occur. Therefore, a retaining piece 4a is formed on the case cover 4 as shown in FIG.
The case body 2 is brought into contact with the retaining piece 4a.
Can not be pulled out from the front side. In the above-described embodiment, the hook 43 is engaged with the lower surface of the case plate 3. However, an opening through which the hook 43 enters the bent piece around the case plate 3 is provided. You may make it engage. In the above embodiment, the projection 42 is provided so as to project downward, and the projection 42 is inserted into the window hole 35 formed in the case plate 3.
Is inserted to restrict the movement of the claw 43.
The movement of the claw 43 is limited by providing a protrusion that protrudes upward on the case plate and attaching the horizontally projecting protrusion to the protrusion from the inside in the left-right direction with the case cover 4 attached to the case plate 3. Can also. In the above embodiment, the present invention has been described by taking a gas stove as an example. However, the present invention can be applied to all appliances using a battery as a power source, such as other cookers and heaters. As is clear from the above description, according to the present invention, since the inclined surface is formed at the end of the ceiling surface of the case cover, the battery in the case main body is stored when the case main body is stored. Even when the battery rises, the battery does not hit the ceiling surface, and the case body can be stored smoothly.
