Description

  The present invention relates to a range hood that collects oil from oily smoke generated by cooking.

  A range hood installed in a kitchen or the like inhales steam or smoke generated by cooking under the range hood together with the air flow generated by the fan, and the oil smoke or the like together with the inhaled air to the outdoors. It is what is discharged. However, it is not environmentally preferable to discharge the oil contained in the oil smoke to the outside as it is, and the oil is attached to equipment such as fans and ducts that are usually present downstream of the range hood in the air flow path for cleaning, etc. A large amount of labor / cost is required for maintenance of the equipment, and the deterioration of the equipment is promoted.

  Therefore, conventionally, the hood has been devised in many ways for capturing and collecting the oil contained in the oil smoke in a filter or the like. For example, many structures that collect oil captured by a grease filter or oil attached to the inner surface of the hood into an oil reservoir using the inclination of the filter or the like are employed. The oil reservoir is detachably attached to the range hood, and the oil accumulated in the oil reservoir due to the use of the range hood is removed after the oil reservoir is removed. Thereafter, the oil sump is appropriately washed and then attached to the range hood again.

  For example, Patent Document 1 discloses a structure in which a flange portion around an oil sump is simply hooked to an engaging claw provided on the range hood side.

Japanese Utility Model Publication No. 55-137054

  However, with this structure, there is no wearing feeling (operating feeling) at the time of wearing, and it is difficult to know which position is the normal position. In addition, since the hook structure is simply adopted, there is a possibility that it may come off unintentionally when a human hand or the like touches carelessly.

  Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to improve the operability and provide a high-class feeling by giving an accurate wearing feeling when the oil sump is attached or detached. Furthermore, it is to provide a range hood with improved safety by preventing it from being inadvertently removed because it can be in a stable wearing state.

In order to solve the above problems, a blower inside the hood, a filter upstream of the air flow generated from the blower, an oil sump for collecting and storing the oil captured by the filter and the hood, and a slidable oil sump The oil reservoir has a support portion for supporting and a protrusion portion that can be projected and retracted in the front-rear direction of the protrusion, and the oil sump includes a guide portion and an engaging step portion provided to extend from the guide portion, When attaching and detaching to the hood, the protrusion and support part hold the oil sump, the oil sump guide part slides in contact with the protrusion, and the protrusion attaches and detaches the oil sump to or from the range hood. In the process, a range hood characterized by passing through an engaging step is provided.
According to this, it is possible to improve the operability by producing an accurate wearing feeling at the time of attaching and detaching the oil sump, to produce a high-class feeling, and to be in a stable wearing state. Thus, it is possible to provide a range hood with improved safety.

Further, the guide portion may have a first inclined surface so as to retract the protrusion when the oil sump is slid to be attached to the range hood.
According to this, when mounting | wearing, it can guide smoothly with small force.

Further, the guide portion may have a second inclined surface that is parallel to a direction in which the oil sump is slid when the oil sump is attached to the range hood and guides the protruding portion to the first inclined surface. .
According to this, at the time of mounting, even if the position where the guide portion slides while coming into contact with the projection portion is slightly shifted, it can be guided to the normal position.

Furthermore, the protruding portion may be capable of appearing and retracting by being biased in the protruding direction.
According to this, it is possible to easily adjust the mounting feeling by the elastic coefficient of the elastic body that biases the protrusion.

  As described above, according to the present invention, it is possible to improve the operability by providing an accurate wearing feeling when the oil sump is attached / detached, to produce a high-class feeling, and to achieve a stable wearing state. Therefore, it is possible to provide a range hood that is prevented from being inadvertently removed and improved in safety.

Hereinafter, embodiments according to the present invention will be described with reference to the drawings.
<First Example>
FIG. 1 is a front view of a range hood 1 according to the first embodiment of the present invention, and FIG. 2 is a perspective view of the range hood 1 as viewed from the lower right. The range hood 1 is provided above the cooker, and includes a thin flat hood 10 at the lower portion of the range hood 1 for capturing air containing oily smoke or water vapor generated by cooking. The hood 10 is provided with a current plate 30 so as to form a gap with the inner peripheral edge of the hood 10. A blower box 20 including a blower (not shown) that generates an air flow therein is provided at the top of the hood 10. Further, a filter 12 is provided around the connecting portion between the blower box 20 and the hood 10.

  The air captured by the hood 10 rides on the air flow generated from the lower side to the upper side generated by the blower, and is sucked from the gap between the hood 10 and the current plate 30. It passes through the space between the hood inner surface 11, is guided to a flue formed around the filter 12, and passes through the filter 12 that removes oily smoke and the like. Then, it discharges | emits outdoors etc. by the exhaust duct which is not shown in figure connected to the exhaust port 21 provided in the air blower box 20. FIG. The hood is not limited to a thin and flat shape, and may be a hood having a large capture space and a thickness in the vertical direction.

  Oil smoke generated by cooking rides on the air flow generated by the blower and is captured by the hood 10 and adheres to the flue such as the inner surface 11 of the hood and the filter 12. The oil smoke adhering to them may fall down on the upper surface of the current plate 30 when used for a long time. The oil that falls on the upper surface of the rectifying plate 30 is collected backward using a slight inclination of the rectifying plate 30 in the back direction, and is collected in an oil sump 40 mounted on the lower surface of the rectifying plate 30. .

  FIG. 3 is a view for explaining a case where the oil sump is attached to the current plate. A plurality of oil drain holes 36 are provided in the vicinity of the back surface side of the rectifying plate 30, and the oil component that hangs down on the upper surface of the rectifying plate 30 is collected in the oil reservoir 40 through the oil drain holes 36. The current plate 30 includes a support portion 31 that supports the oil sump 40 so as to be slidable. On the other hand, the oil reservoir 40 includes a guide portion (not shown) that is slidably supported by the support portion 31. The oil reservoir 40 is attached to the rectifying plate 30 by hooking the guide portion on the support portion 31 and sliding it on the lower surface of the rectifying plate 30 in the direction along the lower surface (the direction indicated by the arrow D in the figure). The Details will be described later.

  FIG. 4 is a front view of the oil sump 40 in this embodiment, and FIG. 5 is a perspective view. The oil sump 40 is provided with guide portions 41 at positions corresponding to the support portions 31 of the current plate 30, that is, in the present embodiment, at both the left and right ends of the oil sump 40 and in the vicinity of the back side. The guide portion 41 includes an inclined surface formed by inclining downward in the rear side direction and in the bottom surface direction, and an inclined surface formed by inclining downward in the center side of the oil reservoir 40 and in the bottom surface direction. Prepare. Details will be described later.

  The oil sump 40 includes an engaging step 42 on the front side of the guide portion 41. The engagement step portion 42 is formed from a slope that falls in the bottom direction. A small surface parallel to the bottom surface is formed on the front side further than the engagement step portion 42, and a slope that rises in a direction opposite to the bottom surface is formed on the front side further than the small surface. Therefore, the front side from the engagement step portion 42 forms a recess in the longitudinal sectional view in the sliding direction. The oil component pool 43 is provided corresponding to the oil drain hole 36 of the flow regulating plate 30, and receives and collects and stores the oil component depending from the oil drain hole 36.

  FIG. 6 is an exploded view for explaining the support portion 31 and the protrusion 32 included in the current plate 30 of the range hood 1. The protrusion 32 is housed in the protrusion holder 34 together with the elastic body 33, and is pressed from above by the protrusion holder cap 35. Therefore, the protrusion 32 is provided downward by the elastic body 33, that is, at the lower end of the protrusion holder 34. It is urged toward the support portion 31. The protrusion 32 is not in contact with the support 31, and there is a gap between the protrusion 31 and the support 31 so that the guide 41 of the oil sump 40 is interposed as will be described later. Therefore, the protruding portion 32 is urged in the direction in which the protruding portion 32 protrudes, and can protrude and retract in that direction by being urged. According to this, it is possible to easily adjust the mounting feeling by the elastic coefficient of the elastic body that biases the protrusion.

  The protruding portion holder 34 and the protruding portion holder cap 35 are connected to the protruding portion holder 34 from the lower side of the rectifying plate 30 via the protruding portion holder through-hole 37 of the rectifying plate 30, and the protruding portion holder cap 35 is connected to the rectifying plate 30. Mounted from above. If it does so, the support part 31 will appear on the lower side of the rectifying plate 30, and a protrusion 32 will also appear on the lower side of the rectifying plate 30 with a gap to the extent that the guide part 41 enters. In the present embodiment, the protrusion 32 is provided on the current plate 30, but is not limited to this, and may be provided on the inner surface of the hood in the case of a range hood that does not have a current plate.

  FIG. 7 is an enlarged perspective view of the vicinity of the guide portion 41 of the oil sump 40 in the first embodiment according to the present invention. The oil sump 40 has a guide portion 41 at both left and right ends, and an engagement step portion 42 provided to extend from the guide portion 41 to the front side. More specifically, the guide portion 41 has a small engagement piece that forms a surface parallel to the sliding direction D of the oil reservoir 40 with the rectifying plate 30 at a position corresponding to the support portion 31 of the rectifying plate 30 and on the back surface. At the end of the side. This engaging piece becomes a portion that is hooked and supported by the support portion 31 of the rectifying plate 30 when the oil reservoir 40 is slid and mounted on the rectifying plate 30.

  A relatively gentle first inclined surface 411 extending toward the rectifying plate 30 (upward) is extended on the front side of the engagement piece. Further, on the front side of the first inclined surface 411, a surface parallel to the engaging piece, that is, parallel to the sliding direction D with the rectifying plate 30 is further extended. Furthermore, on the front side, an engagement step portion 42 formed as an inclined surface falling in the bottom direction is provided. Further, a stopper portion having a shape in which the engagement piece is bent downward is provided on the front side (the direction opposite to the slide direction D) from the engagement step portion 42.

  The guide portion 41 further includes a second inclined surface 412 that is parallel to the direction in which the oil reservoir 40 is slid when the oil reservoir 40 is attached to the range hood 1 and that guides the protruding portion 32 to the first inclined surface 411. Have. More specifically, the guide portion 41 includes a second inclined surface 412 that is an inclined surface from the left and right end portions of the oil reservoir 40 toward the center and is inclined downward in the bottom surface direction. According to this, when the user tries to attach the oil reservoir 40 to the rectifying plate 30, even if the guide portion 41 is slightly displaced in the left-right direction when viewed from the front, that is, sliding while abutting against a projection portion described later. Even if the position to be shifted slightly deviates, it can be guided to the normal position.

  Here, the sliding of the guide part 41 and the protrusion part 32 is demonstrated using FIG. FIG. 8A shows a longitudinal sectional view in the sliding direction D of the guide portion 41 ′ that does not include the first inclined surface 411. That is, the guide portion 41 ′ includes a surface parallel to the sliding direction D with the current plate 30 as a guide portion. When the user tries to install the oil sump 40, the tip of the guide portion 41 ′ collides with the lower portion of the projection portion 32. However, the projection portion 32 can be raised and lowered in the protruding direction, so that it is lifted upward by the guide portion 41 ′. . Since the protrusion 32 is urged downward by the spring, the protrusion 32 abuts on the upper surface of the guide portion 41 ′ after being lifted upward. In this state, the oil sump 40 moves in the sliding direction D in order to be completely attached. Therefore, when the oil sump 40 is attached to and detached from the range hood 1, the guide portion 41 of the oil sump 40 contacts the protrusion 32. Slide while touching.

  When the oil reservoir 40 is further moved in the sliding direction D in order to completely attach the oil reservoir 40, the protrusion 32 reaches the engagement step portion 42 while sliding. When the protruding portion 32 reaches the engaging step portion 42, the protruding portion 32 is biased downward, and thus suddenly protrudes downward along the engaging step portion 42 having a steeply inclined surface. Since the engagement step portion 42 suddenly protrudes, it is possible to give a feeling of wearing when the oil sump 40 is attached, thereby improving the operability and producing a high-class feeling.

  The protrusion 32 suddenly protrudes, passes through the engagement step 42, and reaches a recess positioned below the engagement step 42. The protrusion 32 may or may not contact the recess. In any case, it is possible to give a feeling of wearing when the oil reservoir 40 is attached. However, it is preferable that the protrusion 32 abuts on the recess. This is because the oil reservoir 40 can be reliably held by the protrusion 32 and the support 31.

  Further, when the oil reservoir 40 is removed from the current plate 30, the oil reservoir 40 is moved in the direction opposite to the direction D to be slid for mounting. Then, in order for the protrusion 32 to be lifted up along the steeply inclined engaging step 42, the user needs to move with a relatively large force only at the beginning. This prevents the oil reservoir 40 from being inadvertently removed, and improves safety.

  FIG. 8B shows a longitudinal sectional view in the sliding direction D of the guide portion 41 having the first inclined surface 411. When the user tries to mount the oil reservoir 40, the tip of the guide portion 41 does not collide with the protruding portion 32. Accordingly, the protrusion 32 first comes into contact with the first inclined surface 411 having a gentle inclination and can be raised and lowered in the protruding direction, so that it is gradually lifted upward by the first inclined surface 411. That is, when the oil reservoir 40 is slid to be attached to the range hood 1, the first inclined surface 411 gradually retracts the protrusion 32. According to this, when mounting | wearing, it can guide smoothly with small force. Since the oil sump 40 moves in the direction of the slide direction D to be completely attached, the guide portion 41 slides while coming into contact with the protruding portion 32 when the oil sump 40 is attached to and detached from the range hood 1.

  When the oil reservoir 40 is further moved in the sliding direction D in order to completely attach the oil reservoir 40, the protrusion 32 reaches the engagement step portion 42 while sliding. When the protruding portion 32 reaches the engaging step portion 42, the protruding portion 32 is biased downward, and thus suddenly protrudes downward along the engaging step portion 42 having a steeply inclined surface. Since the engagement step portion 42 suddenly protrudes, it is possible to give a feeling of wearing when the oil sump 40 is attached, thereby improving the operability and producing a high-class feeling.

  Further, when the oil reservoir 40 is removed from the current plate 30, the oil reservoir 40 is moved in the direction opposite to the direction D to be slid for mounting. Then, in order for the protrusion 32 to lift up along the steeply inclined engaging step 42, the user needs to move with a relatively large force only at the beginning. And the safety of the first inclined surface 411 is gradually reduced because the pressing force from the protrusion 32 is gradually weakened at the portion in contact with the first inclined surface 411.

  FIGS. 9A and 9B are explanatory views of a cross section when the oil reservoir 40 in the range hood 1 of the present embodiment is attached to the current plate 30. FIG. 9A is before the oil reservoir slides, and FIG. When sliding while abutting the portion 41, (C) is just before the projection 32 passes through the engagement step 42, and (D) is an oil sump when the projection 32 passes through the engagement step 42. 40 shows the time when 40 is attached to the current plate 30.

  (A) is a figure when the user presses the oil sump 40 against the lower surface of the rectifying plate 30 and tries to slide it in the sliding direction D in order to mount it. The protrusion 32 is pushed downward by the elastic body 33, but has a gap that allows the tip of the guide portion to be inserted from the support portion 31. The tip of the guide portion 41 of the oil reservoir 40 is in a position where it can be inserted into the gap if it moves in the sliding direction D.

  (B) shows the time when the oil reservoir 40 is moved in the sliding direction D for mounting, and the protrusion 32 is in contact with the first inclined surface 411 and is sliding. The first inclined surface 411 gradually retracts the protrusion 32. According to this, when mounting | wearing, it can guide smoothly with a small initial force.

  (C) shows a state before the protrusion 32 passes through the first inclined surface 411 and reaches the engagement step 42. Since the protrusion 32 does not retreat, the drag force when sliding the oil reservoir 40 is constant.

  (D) shows a state after the protrusion 32 has passed through the engagement step 42, that is, a state where the oil reservoir 40 is attached to the rectifying plate 30. When the protrusion 32 passes through the engagement step 42, the protrusion 32 suddenly protrudes downward due to the steep slope of the engagement step 42. By doing so, it is possible to give a feeling of mounting such as a clicking sound or feel when the oil sump 40 is mounted, improving operability and producing a high-class feeling. At this time, the stopper portion collides with the support portion 31, so that the slide of the oil sump 40 can be stopped at the correct position.

  When the oil reservoir 40 is removed from the current plate 30, the same state transition occurs in the reverse order (D) → (C) → (B) → (A). Then, in order for the protrusion 32 to lift up along the steeply inclined engaging step 42, the user needs to move with a relatively large force only at the beginning. And the safety of the first inclined surface 411 is gradually reduced because the pressing force from the protrusion 32 is gradually weakened at the portion in contact with the first inclined surface 411.

  The above-described range hood 1 includes a blower inside the hood 10, a filter 12 on the upstream side of the air flow generated from the blower, an oil reservoir 40 that collects and stores the oil captured by the filter 12 and the hood 10, and an oil reservoir. The oil reservoir 40 is provided with a guide portion 41 and an engagement provided extending from the guide portion 41. When the oil reservoir 40 is attached to and detached from the range hood 1, the protruding portion 32 and the support portion 31 hold the oil reservoir 40, and the guide portion 41 of the oil reservoir 40 is in contact with the protruding portion 32. The protruding portion 32 slides and passes through the engaging step portion 42 in the process of attaching and detaching the oil reservoir 40 to or from the range hood 1. According to this, by giving an accurate wearing feeling when the oil sump 40 is attached / detached, the operability is improved and a high-class feeling is produced, and furthermore, a stable wearing state can be achieved, so that it is inadvertently detached. Thus, it is possible to provide a range hood with improved safety.

<Second Example>
In the description of the present embodiment, only points different from the first embodiment are described in order to avoid repeated description.
FIG. 10 is a diagram for explaining a case where the oil sump is attached to the current plate. A plurality of oil drain holes 36A are provided in the vicinity of the back surface side of the rectifying plate 30A, and the oil that hangs down on the upper surface of the rectifying plate 30A is collected in the oil reservoir 40A through the oil drain holes 36A. The rectifying plate 30A includes a support portion 31A that slidably supports the oil sump 40A. On the other hand, the oil reservoir 40A includes a supported portion (not shown) that is slidably supported by the support portion 31A. The oil sump 40A is attached to the rectifying plate 30A by hooking the supported portion to the supporting portion 31A and sliding the rectifying plate 30A on the lower surface of the rectifying plate 30A in the direction along the lower surface (the direction indicated by the arrow D in the figure). Is done.

  FIG. 11 shows a perspective view of an oil sump 40A in the present embodiment. The oil sump 40A is provided with a supported portion 44A at a position corresponding to the support portion 31A of the rectifying plate 30A, that is, at an intermediate position between the left and right ends and the center portion of the oil sump 40A and in the vicinity of the back side. . The supported portion 44A is parallel to the lower surface of the rectifying plate 30A, has a sufficient width (length in a direction perpendicular to the sliding direction D) to be caught by the supporting portion 31A, and the protruding portion 32A passes through the engaging step portion 42A. A sufficient length (length in the sliding direction D). Further, a stopper portion having a shape in which the engagement piece is bent downward is provided on the front side (the direction opposite to the slide direction D) of the engagement step portion 42A.

  The oil sump 40A includes a guide portion 41A in the central portion of the oil sump 40A as viewed from the front and in the vicinity of the back side. The guide portion 41A includes an inclined surface formed to be inclined downward in the rear side direction and in the bottom side direction. The oil sump 40A includes an engaging step 42A on the front side of the guide portion 41A. The engaging step 42A is formed from a slope that falls in the bottom direction. A small surface parallel to the bottom surface is formed on the front side of the engaging step 42A. The oil pool 43A is provided corresponding to the oil drain hole 36A of the rectifying plate 30A, receives and collects and stores the oil drooping from the oil drain hole 36A.

  FIG. 12 is an explanatory view of a section near the protrusion when the oil sump in the range hood of the present embodiment is attached to the current plate, and (A) is when the protrusion starts to contact the guide section ( (B) shows the time immediately before the protruding portion passes through the engaging stepped portion, and (C) shows the time when the protruding portion passes through the engaging stepped portion and the oil reservoir is attached to the current plate. Similar to the first embodiment, the protrusion 32A is urged downward by an elastic body (not shown) from the back side.

  (A) is a figure when the user presses the oil reservoir 40A against the lower surface of the rectifying plate 30A and starts to slide in the sliding direction D in order to attach it. The protrusion 32A protrudes from the lower surface of the rectifying plate 30A by a length substantially the same as the distance between the rear-side end portion of the first inclined portion 411A and the lower surface of the rectifying plate 30A. Therefore, as the first inclined portion 411A is slid in the sliding direction D, the first inclined portion 411A comes into contact with the side surface of the protruding portion 32A without collision. In addition, the range hood of a present Example does not have a 2nd inclined surface.

  (B) shows the time when the oil reservoir 40A is moved in the sliding direction D to be mounted, and the protrusion 32A is in contact with and slides on the first inclined surface 411A. Since the protrusion 32A is provided so as to be able to protrude and retract in the protrusion direction, the first inclined surface 411A gradually retracts the protrusion 32A. According to this, when mounting | wearing, it can guide smoothly with a small initial force.

  (C) shows a state after the protruding portion 32A has passed through the engaging stepped portion 42A, that is, a state where the oil sump 40A is attached to the rectifying plate 30A. Since the protrusion 32A is biased downward in the protrusion direction, the protrusion 32A suddenly protrudes downward due to the steep slope of the engagement step 42A when passing through the engagement step 42A. By doing so, it is possible to provide a feeling of mounting such as a clicking sound or feel when the oil sump 40A is mounted, and it is possible to improve the operability and produce a high-class feeling.

  Further, when the oil sump 40A is removed from the current plate 30A, the same state transition occurs in the reverse order of (C) → (B) → (A). Then, in order for the protrusion 32A to lift up along the steeply inclined engaging step 42A, the user needs to move it with a relatively large force only at the beginning. And the safety of the first inclined surface 411A is gradually reduced because the pressing force from the protrusion 32A is gradually weakened at the portion in contact with the first inclined surface 411A.

  FIGS. 13A and 13B are explanatory views of a cross section in the vicinity of the support portion when the oil sump in the range hood of the present embodiment is attached to the current plate. FIG. 13A is before the sump slide, and FIG. (C) shows the time when the protruding portion passes through the engaging stepped portion and the oil sump is attached to the current plate.

  (A) is a figure when the user is trying to slide the oil reservoir 40A against the lower surface of the current plate 30A and slide it in the sliding direction D in order to mount it. A gap slightly larger than the thickness of the supported portion 44A is provided between the support portion 31A and the lower surface of the rectifying plate 30A. The supported part 44A enters the gap when it is slid in the sliding direction D while being in contact with the lower surface of the current plate 30A.

  (B) shows a time when the oil reservoir 40A is moved in the sliding direction D for mounting, and the supported portion 44A enters the gap between the support portion 31A and the lower surface of the rectifying plate 30A. Since the supported portion 44A is parallel to the lower surface of the rectifying plate 30A, when supported, the supported portion 44A can be smoothly guided with a small force. In addition, the state of (B) is a state corresponding to (A) of FIG. 12 in terms of the relationship between the protrusion 32A and the first inclined surface 411A.

  (C) shows a state after the protruding portion 32A has passed through the engaging stepped portion 42A, that is, a state where the oil sump 40A is attached to the rectifying plate 30A. The supported portion 44A is reliably supported by the support portion 31A at the deepest position. That is, when the stopper portion collides with the support portion 31A, the slide of the oil sump 40 is stopped and supported at the correct position.

  The above-described range hood 1A includes a blower inside the hood 10A, a filter 12A on the upstream side of the air flow generated from the blower, an oil sump 40A that collects and stores oil captured by the filter 12A and the hood 10A, and an oil sump. A support portion 31A that slidably supports 40A, and a protrusion portion 32A that can protrude and retract in the front-rear direction of the protrusion, and the oil sump 40A is an engagement provided by extending from the guide portion 41A and the guide portion 41A When the oil reservoir 40A is attached to and detached from the range hood 1A, the protruding portion 32A and the support portion 31A hold the oil reservoir 40A, and the guide portion 41A of the oil reservoir 40A is in contact with the protruding portion 32A. The protrusion 32A slides and engages the engaging step 42A in the process of attaching and detaching the oil sump 40A to or from the range hood 1A. It is characterized in that over to. According to this, it is possible to improve the operability by providing an accurate wearing feeling when the oil sump 40A is attached / detached, to produce a high-class feeling, and to be in a stable wearing state. Thus, it is possible to provide a range hood with improved safety.

In addition, this invention is not limited to the illustrated Example, The implementation by the structure of the range which does not deviate from the content described in each item of a claim is possible.
In the first embodiment and the second embodiment, an example is shown in which the protrusion is urged downward by the elastic body, but the protrusion that slides while abutting the guide is attached downward, that is, in the direction of the guide. For example, a method in which the protrusion is integrally formed as a part of the leaf spring and is biased by the restoring force of the leaf spring, or the protrusion is molded with an elastic resin, etc. It may be energized by a restoring force due to its own elastic deformation.
