Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a ceiling-mounted electrical appliance with a maintenance function. Background Art

[0002] Yuba, also known as bathroom heater, is a ceiling appliance that can deliver air to the room to heat or insulate the room, or to renew the indoor air, along with ventilation fans and fresh air blowers. Taking Yuba as an example, existing Yuba also includes maintenance lamps.

[0003] Existing bathroom heaters usually adopt a design that the maintenance lamp is fixedly installed on the body panel. Due to the high temperature and high humidity in the bathroom environment, the maintenance lamp is exposed for a long time, which reduces the reliability and durability of the maintenance lamp and weakens the performance and efficacy of the beauty lamp. Utility Model Content

[0004] In view of this, the utility model provides a ceiling appliance equipped with a bathroom heater, which has poor reliability and is capable of improving and optimizing the reliability and durability of a maintenance lamp, and improving or maintaining the performance and efficacy of the maintenance lamp.

[0005] The utility model provides a ceiling-mounted appliance with a maintenance function, which includes a body and a maintenance lamp. The maintenance lamp is movably arranged on the body and includes a light-emitting portion. The maintenance lamp is configured to be able to switch between a working position and a parking position. The light-emitting portion faces indoors when the maintenance lamp is in the working position, and faces away from indoors when the maintenance lamp is in the parking position.

[0006] Compared with the prior art, the ceiling appliance with maintenance function of the utility model allows the maintenance lamp to move relative to the body, that is, it allows the maintenance lamp to be switched to a docked position when the maintenance and beauty function is not enabled, thereby preventing the light-emitting part from contacting impurities such as high-temperature and high-humidity air mist in the bathroom, reducing the exposure time of the light-emitting part in the bathroom, thereby improving the reliability and durability of the maintenance lamp, reducing the risk of failure of the maintenance lamp, and enabling the maintenance lamp to maintain good radiation maintenance performance and efficacy for a longer period of time.

[0007] In one embodiment, the maintenance lamp further includes a backlight portion disposed opposite to the light-emitting portion, and the backlight portion faces indoors when the maintenance lamp is in the parking position.

[0008] With such arrangement, the backlight blocks the light-emitting part from the internal environment of the bathroom when the maintenance lamp is in the parked position, further weakening the erosion of the light-emitting part by the high temperature and high humidity environment in the bathroom. In addition, as the part where the heat of the maintenance lamp is relatively concentrated, the backlight can undergo convection heat exchange with the indoor air when it is set facing the room, thereby dissipating heat into the room and better maintaining the performance stability of the maintenance lamp.

[0009] In one embodiment, the maintenance lamp includes a lamp board and a light-emitting body arranged on a side of the lamp board, the light-emitting part includes the light-emitting body, and the backlight part includes a side of the lamp board away from the light-emitting body.

[0010] With such arrangement, the composition and structure of the maintenance lamp are simple and easy to obtain.

[0011] In one embodiment, the body includes a bottom plate facing indoors and having a light outlet. When the maintenance lamp is in a working position, the light-emitting portion is located on a side of the maintenance lamp relatively close to the bottom plate and faces indoors through the light outlet.

[0012] With such arrangement, in the extension direction of the base plate, the overall size of the ceiling appliance with maintenance function is smaller, the overall structure is more compact, the light-emitting part of the maintenance lamp is closer and more concentrated to the functional components arranged on the base plate, thereby making it convenient for users to enable the maintenance and beauty function and other auxiliary functions at the same time.

[0013] In one embodiment, the body has a rotation space, which is located on a side of the bottom plate away from the interior of the room and penetrates the bottom plate to form a light outlet, and the maintenance lamp is rotatably disposed in the rotation space.

[0014] With this arrangement, the maintenance lamp can be better protected, and the maintenance lamp is arranged in the rotating space, which also makes it easier to install the fuselage into the ceiling or suspended ceiling space.

[0015] In one embodiment, the maintenance lamp is adapted to the inner wall of the light outlet to close the light outlet when in the working position and the parking position.

[0016] With such an arrangement, the maintenance lamp can block the high-temperature and high-humidity air in the bathroom from entering the body through the light outlet when it is in the working position and the parking position, so that the functional components in the body can be better protected.

[0017] In one embodiment, the maintenance lamp is matched with the inner wall of the rotation space when in the working position and the parking position to close at least a portion of the rotation space.

[0018] With such an arrangement, the maintenance lamp can block the high-temperature and high-humidity air in the bathroom from entering the rotating space when it is in the working position and the parking position, so that the functional components in the body are better protected.

[0019] In one embodiment, a driving unit is also included, and the driving unit includes a commutator connected to the maintenance lamp, and the commutator is used to drive the maintenance lamp to rotate around a commutation axis to switch the position of the maintenance lamp, and the commutation axis is not parallel to the load-bearing direction of the fuselage.

[0020] In one embodiment, the reversing axis is perpendicular to the load-bearing direction of the fuselage.

[0021] In one embodiment, the maintenance lamp includes a first edge and a second edge disposed opposite to each other, and the reversing axis is formed between the first edge and the second edge.

[0022] With this arrangement, it is easier for the maintenance lamp to maintain a stable center of gravity when it rotates relative to the body, and the overall stability of the ceiling appliance with maintenance function is also higher.

[0023] In one embodiment, a driving unit is further included, and the driving unit includes a shifter connected to the maintenance lamp, and the shifter is used to drive the maintenance lamp to move up and down so that the maintenance lamp is closer to and farther away from the room.

[0024] With such an arrangement, the distance between the light-emitting part of the maintenance lamp and the human body can be adjusted, thereby changing the size of the light spot of the maintenance light irradiating the human body, and further changing the degree to which the human body absorbs the energy of the maintenance light.

[0025] In one embodiment, it also includes a driving unit, which also includes a commutator connected to the maintenance lamp, the commutator is used to drive the maintenance lamp to rotate around the commutation axis to switch the position of the maintenance lamp, the shifter includes an output member movably arranged on the fuselage, and a driver connected to the output member, the commutator is installed on the output member, and the driver is used to drive the output member to move along a lifting trajectory that is not perpendicular to the load-bearing direction of the fuselage.

[0026] With such arrangement, the maintenance lamp can change its position and posture, realizing multi-dimensional adjustment of the maintenance lamp, so that the maintenance lamp in different posture states can form good coordinated cooperation with the fuselage, and the position change and posture change of the maintenance lamp will not conflict. The shifter is dedicated to the position change of the maintenance lamp, and the commutator is dedicated to the posture change of the maintenance lamp. The posture change efficiency of the maintenance lamp is higher, and the action control logic of the posture change is simpler. The maintenance lamp adjusts the distance between the light-emitting part and the human body by moving.

[0027] In one of the embodiments, when the maintenance lamp is in the working position, the driver drives the maintenance lamp to a position where the light-emitting portion is flush with a side of the body close to the room.

[0028] With this arrangement, the side of the fuselage close to the room is flatter, the size of the light spot formed by the maintenance light emitted by the light-emitting part irradiating the human body is maximized, and at the same time the light-emitting part will not interfere with the user under the fuselage.

[0029] In one embodiment, the maintenance lamp includes a first edge and a second edge symmetrically arranged about a reversing axis, the fuselage includes a first longitudinal wall and a second longitudinal wall spaced apart, the maintenance lamp is movably and rotatably arranged between the first longitudinal wall and the second longitudinal wall, the first edge and the second edge respectively adapt to the first longitudinal wall and the second longitudinal wall when the maintenance lamp is in a working position, and respectively adapt to the second longitudinal wall and the first longitudinal wall when the maintenance lamp is in a docking position.

[0030] With such arrangement, the maintenance lamp will not interfere with the first longitudinal wall and the second longitudinal wall during the position switching process, and can also achieve the closure of the internal space of the fuselage in the working position and the parking position respectively to prevent the high temperature and high humidity air in the bathroom from invading the interior of the fuselage along the first longitudinal wall and the second longitudinal wall.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0038] Traditional heaters are used to deliver warm air to the room to heat or insulate the room. Most heaters are installed in bathrooms to heat or insulate the bathroom. Based on traditional heaters, some improved heaters also include maintenance lamps, which are also called beauty lamps. They are devices that can generate maintenance light and sterilize and maintain the skin through the energy of the maintenance light, thereby achieving maintenance and beauty effects.

[0039] The utility model provides a ceiling appliance 100 with a maintenance function, comprising a body 10, a maintenance lamp 20 and a driving unit. The ceiling appliance 100 with a maintenance function of the utility model has both a maintenance and beauty function and an indoor air regulation function, and can be installed and used in a bathroom or in other indoor places. When the ceiling appliance 100 with a maintenance function is a heater installed in a bathroom, the body 10 can be arranged in the ceiling space formed between the bathroom ceiling and the ceiling board.

[0040] The ceiling appliance 100 with maintenance function can be a heater equipped with maintenance lamp 20, or a ventilation fan or fresh air blower equipped with maintenance lamp 20. The following takes a heater equipped with maintenance lamp 20 as an example to introduce the ceiling appliance 100 with maintenance function of the present invention.

[0041] Specifically, the maintenance lamp 20 includes a light-emitting portion 201 for emitting maintenance light to radiate energy to human skin, and the maintenance lamp 20 can be movably arranged on the fuselage 10. The driving unit is connected to the maintenance lamp 20, and is used to drive the maintenance lamp 20 to switch between at least a working position and a parking position. When the driving unit drives the maintenance lamp 20 to move relative to the fuselage 10 so that the light-emitting portion 201 faces the room, the maintenance lamp 20 is in the working position. When the driving unit drives the maintenance lamp 20 to move relative to the fuselage 10 so that the light-emitting portion 201 faces away from the room, the maintenance lamp 20 is in the parking position.

[0042] Optionally, when the maintenance lamp 20 is in the working position, the light-emitting portion 201 emits maintenance light to the room and the human body, and when the maintenance lamp 20 is in the parking position, the light-emitting portion 201 stops emitting maintenance light.

[0043] In one embodiment, the maintenance lamp 20 is rotatably disposed on the fuselage 10, and the driving unit drives the maintenance lamp 20 to rotate relative to the fuselage 10 around a preset reversing axis to change the posture of the maintenance lamp 20, thereby changing the direction of the light-emitting part 201, thereby switching the maintenance lamp 20 between the working position and the docking position.

[0044] Furthermore, in one embodiment, the body 10 includes a base plate 12 for being set toward the indoor room and having a light outlet 122. When the driving unit drives the maintenance lamp 20 to a working position, the light-emitting portion 201 is visible to indoor users through the light outlet 122. At this time, the light-emitting portion 201 is facing the indoor room through the light outlet 122.

[0045] Furthermore, in one embodiment, the maintenance lamp 20 also includes a backlight portion 202 disposed opposite to the light-emitting portion 201. When the maintenance lamp 20 is in the docked position, the backlight portion 202 of the maintenance lamp 20 faces the interior of the room.

[0046] Specifically, when the driving unit drives the maintenance lamp 20 to the parking position, the backlight 202 is visible to indoor users through the light outlet 122 , and at this time, the backlight 202 is directed toward the indoor through the light outlet 122 .

[0047] See also Figure 1-2 In some embodiments, the maintenance lamp 20 includes a lamp board 21 and a light-emitting body 22 for generating maintenance light. The number of the light-emitting bodies 22 can be one or more. The multiple light-emitting bodies 22 can be randomly dispersed on one side of the lamp board 21, or can be arranged in a queue or array on one side of the lamp board 21. The light-emitting portion 201 includes the light-emitting body 22 and the side of the lamp board 21 on which the light-emitting body 22 is provided, and the backlight portion 202 includes the other side of the lamp board 21 away from the light-emitting body 22.

[0048] See also Figure 1-2 In some embodiments, the body 10 includes a bottom plate 12 and a hollow chassis 11. When the ceiling appliance 100 with a maintenance function is installed in a bathroom, the chassis 11 is arranged in a ceiling space formed between the bathroom ceiling and the ceiling board. The side of the chassis 11 relatively close to the room is exposed through a ceiling through hole opened in the ceiling board, and the bottom plate 12 is installed on the side of the chassis 11 relatively close to the room.

[0049] Optional, see Figure 1-2 , Figure 3-4 When the chassis 11 is arranged in the ceiling space, the bottom plate 12 is a horizontally arranged flat plate, the light-emitting portion 201 is horizontally arranged parallel to the ground when the maintenance lamp 20 is in a working position, and the backlight portion 202 is horizontally arranged parallel to the ground when the maintenance lamp 20 is in a docking position.

[0050] Further, see Figure 1-2 , Figure 3-4 A rotation space 111 is provided in the chassis 11. The rotation space 111 is located on a side of the bottom plate 12 relatively away from the room and passes through the bottom plate 12 to connect to the light outlet 122. The maintenance lamp 20 is rotatably provided in the rotation space 111 and switches its position in the rotation space 111.

[0051] Specifically, the fuselage 10 includes a first longitudinal wall 1121 and a second longitudinal wall 1122 that are spaced apart and disposed opposite to each other. Figure 1-2 The rotation space 111 is located between the first longitudinal wall 1121 and the second longitudinal wall 1122. The first longitudinal wall 1121 and the second longitudinal wall 1122 form the inner wall surface of the rotation space 111. When the maintenance lamp 20 is in the working position and in the docking position, the two oppositely disposed edges of the maintenance lamp 20 are respectively adapted to the first longitudinal wall 1121 and the second longitudinal wall 1122.

[0052] With such arrangement, the size of the rotating space 111 is appropriate, which can satisfy the rotation of the maintenance lamp 20 relative to the body 10 to complete the posture switching, and will not cause waste of the internal space of the chassis 11.

[0053] Optionally, in some embodiments, a side of the bottom plate 12 away from the chassis 11 forms a bottom side 121 of the fuselage 10. When the chassis 11 is arranged in place in the ceiling space, the bottom side 121 faces the room and the ground. No matter how the maintenance lamp 20 is rotated relative to the fuselage 10, the maintenance lamp 20 does not protrude from the bottom side 121. With this arrangement, the maintenance lamp 20 will not affect the user located under the fuselage 10.

[0054] Optionally, when the maintenance lamp 20 is in the working position and the docked position, the periphery of the maintenance lamp 20 corresponds to the inner wall surface of the rotation space 111, so that the maintenance lamp 20 in the working position and the docked position can close at least part of the rotation space 111, that is, close the part of the rotation space 111 located relatively far away from the room where the maintenance lamp 20 is located, so as to prevent indoor moisture, dust, and high-temperature gas from entering the fuselage 10.

[0055] Furthermore, the inner wall of the rotating space 111 extends toward the bottom plate 12 and the interior of the room to form an inner wall surface of the light outlet 122. When the maintenance lamp 20 is in a working position or in a docked position, the periphery of the maintenance lamp 20 corresponds to the inner wall surface of the light outlet 122 to close the light outlet 122, thereby blocking indoor moisture, dust, high-temperature gas, etc. from entering the rotating space 111, thereby preventing adverse effects on the internal components of the fuselage 10.

[0056] Optionally, the inner wall surface of the rotating space 111 extends in a direction perpendicular to the base plate 12 and can be either a plane or a curved surface. When the chassis 11 is arranged in the ceiling space, the figure of the inner wall surface of the rotating space 111 projected onto the horizontal plane can be a closed curve or a closed broken line formed by multiple straight lines.

[0057] It can be understood that in some embodiments, the maintenance lamp 20 includes a light-emitting body 22 and a lamp board 21 that supports the light-emitting body 22 , and the edge and periphery of the maintenance lamp 20 are the edge and periphery of the lamp board 21 .

[0058] In some embodiments, the driving unit includes a commutator 40 disposed on the fuselage 10 and connected to the maintenance lamp 20, and the commutator 40 is used to drive the maintenance lamp 20 to rotate around a commutation axis relative to the fuselage 10 to switch positions. Figure 1-2 In the illustrated embodiment, when the chassis 11 is arranged in the ceiling space, the reversing axis extends in the horizontal direction and is perpendicular to the load-bearing direction of the fuselage 10. The load-bearing direction of the fuselage 10 is in the vertical direction after the fuselage 10 is installed in place, and the horizontal distance from the reversing axis to the first longitudinal wall 1121 is equal to the horizontal distance from the reversing axis to the second longitudinal wall 1122.

[0059] The commutator 40 may be a rotary motor, or other driver 31 or transmission device that can rotate or drive the maintenance lamp 20. When the commutator 40 is a rotary motor, the output shaft of the rotary motor is fixedly connected to the maintenance lamp 20. When the commutator 40 is a transmission gear 311 connected to other driving sources, the maintenance lamp 20 may further include a driven gear 311 meshed with the transmission gear 311, and the driven gear 311 is fixedly connected to the lamp board 21.

[0060] In other embodiments, the extension direction of the reversing axis does not necessarily have to be parallel to the horizontal direction, and the reversing axis does not necessarily have to be parallel to the base plate 12, as long as the reversing axis is not parallel to the load-bearing direction of the fuselage 10, that is, the reversing axis is not parallel to the vertical direction when the chassis 11 is arranged in the ceiling space.

[0061] See also Figure 1-2 The maintenance lamp 20 includes a first edge 211 and a second edge 212 formed on the lamp board 21 and arranged back to back. The first edge 211 and the second edge 212 are respectively adapted to the first longitudinal wall 1121 and the second longitudinal wall 1122 when the maintenance lamp 20 is in the working position. The first edge 211 and the second edge 212 are respectively adapted to the second longitudinal wall 1122 and the first longitudinal wall 1121 when the maintenance lamp 20 is in the docking position. The reversing axis is located between the first edge 211 and the second edge 212.

[0062] In other embodiments, the number of maintenance lamps 20 may be multiple, for example, Figure 1-2 On the basis of the illustrated embodiment, a plurality of maintenance lamps 20 are rotatably disposed on the body 10 around a plurality of reversing axes, respectively. The reversing axes are disposed parallel to each other and are arranged in sequence along the extension direction of the bottom plate 12 .

[0063] In some embodiments, the driving unit further includes a shifter 30 connected to the maintenance lamp 20, and the shifter 30 is used to drive the maintenance lamp 20 to perform lifting movement relative to the body 10 so that the maintenance lamp 20 is closer to and farther away from the room. When the chassis 11 is arranged in place in the ceiling space, the maintenance lamp 20 changes the distance between itself and the ground through lifting movement. The shifter 30 drives the maintenance lamp 20 to descend to approach the ground, so as to bring the light-emitting portion 201 closer to the user.

[0064] Specifically, in some embodiments, the maintenance lamp 20 is arranged in the rotation space 111 between the first longitudinal wall 1121 and the second longitudinal wall 1122. The maintenance lamp 20 can not only be driven by the commutator 40 to rotate in the rotation space 111 to complete the posture switching, but can also be driven by the shifter 30 in the rotation space 111 to move up and down to change the height. The maintenance lamp 20 can rotate and move up and down in the rotation space 111 at the same time, or can rotate and move up and down separately.

[0065] When the maintenance lamp 20 rotates until the light-emitting portion 201 faces the room and is visible to the room through the light outlet 122, the commutator 40 can then stop outputting power, and the maintenance lamp 20 stops rotating. Then the shifter 30 starts and drives the maintenance lamp 20 to keep the light-emitting portion 201 facing the room and move closer to the room and the ground, so that the distance between the light-emitting portion 201 and the light outlet 122 and the bottom plate 12 is gradually reduced. In this way, the distance between the light-emitting portion 201 and the human body can be shortened, and the beam shape and irradiation range of the maintenance light emitted from the light outlet 122 to the room can be changed.

[0066] Optionally, in some embodiments, the shifter 30 includes an output member 32 movably disposed on the fuselage 10, and also includes a driver 31 connected to the output member 32. The driver 31 can be installed on the fuselage 10, and the commutator 40 is installed on the output member 32. The driver 31 is responsible for providing power to make the maintenance lamp 20 move up and down, and by driving the output member 32 to move up and down relative to the fuselage 10, the commutator 40 and the maintenance lamp 20 are driven to move up and down together.

[0067] Specifically, the trajectory of the output member 32 moving relative to the fuselage 10 is not perpendicular to the load-bearing direction of the fuselage 10. When the chassis 11 is arranged in place in the ceiling space, the load-bearing direction of the fuselage 10 is the vertical direction. When the chassis 11 is arranged in place in the ceiling space, the base plate 12 can be a horizontally arranged flat plate structure, and the trajectory of the output member 32 moving up and down relative to the fuselage 10 is not parallel to the base plate 12.

[0068] See also Figure 3-4In some embodiments, the driver 31 includes a driving motor and a gear 311 connected to the output shaft of the driving motor, the output member 32 includes a rack 321 meshing with the gear 311, a sliding connection is formed between the rack 321 and the fuselage 10, the sliding trajectory of the rack 321 relative to the fuselage 10 is the trajectory of the output member 32 moving up and down relative to the fuselage 10, the output member 32 also includes a mounting member fixedly connected to the rack 321, and the commutator 40 is installed on the mounting member.

[0069] Optional, Figure 3-4 In the illustrated embodiment, the rotating space 111 is a spatial region having a rectangular shape, and the first longitudinal wall 1121 and the second longitudinal wall 1122 are arranged parallel to each other. When the chassis 11 is arranged in place in the ceiling space, the first longitudinal wall 1121 and the second longitudinal wall 1122 are both perpendicular to the horizontal plane, and the sliding trajectory of the rack 321 relative to the fuselage 10 is a vertical straight line trajectory. Driven by the meshing of the gear 311, the rack 321 always maintains a vertically extended posture.

[0070] Optionally, when the maintenance lamp 20 is in a working position with the light-emitting part 201 facing the room, the commutator 40 can suspend outputting power, the maintenance lamp 20 maintains its position and the direction of the light-emitting part 201 unchanged, and the shifter 30 can drive the maintenance lamp 20 to the lower limit position so that the light-emitting part 201 is flush with the bottom side 121 when the maintenance lamp 20 is in the lower limit position.

[0071] Optionally, after the maintenance lamp 20 is in a working position with the light-emitting portion 201 facing the indoor room, the shifter 30 outputs a lifting driving power. During the lifting process, the first edge 211 and the second edge 212 formed on the lamp board 21 of the maintenance lamp 20 on opposite sides maintain sliding adaptation with the first longitudinal wall 1121 and the second longitudinal wall 1122 respectively, thereby improving the posture stability of the maintenance lamp 20 during lifting and lowering. The orientation of the light-emitting portion 201 will not change during the lifting and lowering of the maintenance lamp 20, and the area directly below the light outlet 122 can always be illuminated.

[0072] The maintenance lamp 20 is driven to move up and down in the rotating space 111 by the shifter 30, and the beam shape and irradiation range of the maintenance light emitted from the light outlet 122 and directed into the room can change with the height position of the maintenance lamp 20. Among the maintenance light emitted by the light emitting part 201, a part of it is directly emitted from the light outlet 122 to the room, and the other part is blocked by the edge of the light outlet 122 and irradiated to the inner wall surface of the rotating space 111, so the beam shape and irradiation range of the maintenance light are restricted by the edge of the light outlet 122 and the inner wall surface of the rotating space 111.

[0073] Specifically, when the distance from the light-emitting portion 201 to the light outlet 122 and the bottom side 121 decreases, the proportion of the maintenance light blocked by the edge of the light outlet 122 and irradiated to the inner wall of the rotating space 111 decreases, while the proportion of the maintenance light directly emitted from the light outlet 122 to the indoor room increases. That is to say, when the maintenance lamp 20 is in a working position with the light-emitting portion 201 facing the indoor room, as the maintenance lamp 20 gradually approaches the light outlet 122, the bottom side 121 and the indoor room, the constraint and blocking of the maintenance light by the edge of the light outlet 122 and the inner wall of the rotating space 111 is weakened, and the shape of the light beam gradually changes from a columnar shape to a cone shape, thereby expanding the irradiation range of the maintenance light beam.

[0074] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection required by the present invention.
