Description

Technical Field

[0001] The present invention relates to a toilet device. Background Art

[0002] It is known that the seat of an existing toilet device has a heating function. Specifically, a heating device, a control unit, and a sensor (for example, a pressure sensor) are provided inside the seat. When a user sits on the seat, the sensor senses the presence of the user, and the control unit controls according to the output of the sensor to cause the heating device to start operating. In this way, the user will feel the seat getting warmer, thus having a good user experience.

[0003] However, in an existing toilet device, a power supply unit is arranged inside a support body of the toilet device, and the support body supports the seat so that the seat can rotate relative to the support body. In order to supply power to the heating device provided inside the seat and enable the control unit to send an instruction to the power supply unit, the heating device and the control unit are usually electrically connected to the power supply unit inside the support body through a wire harness via a hinge portion that connects the seat and the support body. In this way, when it is necessary to replace or clean the seat, it is difficult for the user to remove the seat. In addition, due to the presence of the wire harness, it is also difficult to clean the hinge portion.

[0004] On the other hand, in an existing toilet device, another detachable structure has been proposed. Specifically, a metal shaft is installed at the hinge portion to replace the wire harness, and the power supply unit supplies power to the metal shaft, and the power is supplied to the heating device provided inside the seat via the metal shaft, thereby performing heating. Since power is supplied through the metal shaft, the seat is detachable. However, in such a structure, at least a part of the metal shaft is exposed during the power-on process. Therefore, during cleaning, a cleaning agent or water may adhere to the energized portion, which may cause a malfunction. And since at least a part of the metal shaft is exposed during the power-on process, there is also a risk that the user may touch this part and get an electric shock.

[0005] In addition, in existing toilet devices, a power supply means based on a pair of coils has also been proposed. Specifically, a pair of planar coils are arranged, with one of them arranged on a support body and the other arranged on a toilet seat ring, and the two are opposed to each other at a certain interval in a direction perpendicular to the coil plane. A power supply unit arranged in the support body supplies power to the coil of the one, and a current flows through this coil to generate a magnetic field. This magnetic field acts on the coil of the other to generate a current in this coil, and this current is supplied to a heating device to generate heat. That is to say, heating is carried out through electromagnetic induction between the pair of planar coils. However, the area of the planar coil is relatively large, requiring a large installation space. When the available space is narrow, it is difficult to arrange, and it will also limit the arrangement of the heating device. In addition, it is also difficult to stably maintain the distance between the planar coils. Summary of the Invention

[0020] Based on the toilet device described in the third or fourth aspect, in the toilet device of the fifth aspect, the elastic material includes a resin material.

[0021] Based on the toilet device described in the second aspect, the toilet device of the sixth aspect further includes a first coil fixing member.

And, a first chamber is formed within the first main body portion.

[0022] Based on the toilet device described in the second or sixth aspect, the toilet device of the seventh aspect further includes a second coil fixing member. The coil fixing member includes a second main body portion and a second flange portion, and the second flange portion is interposed between the second cylindrical coil and the wall portion of the support body.

[0029] Based on the toilet device according to any one of the first to fourth aspects or the sixth aspect, the toilet device according to the tenth aspect further includes a resin housing that covers at least one of the first cylindrical coil and the second cylindrical coil from the outside.

[0030] Advantages of the Invention

[0031] According to the toilet device described in the first aspect, since the wireless power transmission method is adopted, it is easy for the user to remove the seat from the support body, which is convenient for cleaning and replacement. In addition, since the pair of coils are respectively disposed in the support body and the seat, there is no exposed energized part, and the situation where the user gets an electric shock due to touching the energized part can be avoided. Further, the toilet device described in the first aspect uses a pair of cylindrical coils, and the pair of cylindrical coils are arranged such that one of them surrounds at least a part of the other from the outside. Thus, compared with a planar coil, the size of the cylindrical coil with the same number of turns is significantly reduced in the radial direction, and the limitation on the configuration space (especially the requirement for the size of the space in the radial direction of the coil) is significantly reduced, making it easier to configure the coil. On the other hand, by arranging the pair of cylindrical coils such that one surrounds at least a part of the other from the outside, the power transmission rate can be increased compared with a planar coil.

[0032] According to the toilet device described in the second aspect, since the pair of cylindrical coils are respectively disposed in the rotating shaft of the hinge assembly and the wall portion of the support body, there is no exposed part, and it has high safety. In addition, since one of the pair of cylindrical coils is fixed to the rotating shaft of the hinge assembly, the coil can be conveniently replaced when the seat is removed from the support body.

[0033] The toilet device according to the third aspect can prevent the first cylindrical coil from being damaged when the user sits on it. Specifically, when the user sits on the seat portion of the seat ring, the load generated by the user's weight acts on the hinge assembly. Since the first cylindrical coil is fixed to the rotating shaft of the hinge assembly, the first cylindrical coil may be deformed under the action of the above load, and there is a possibility of further damage. By providing a first load absorbing member between the outside of the first cylindrical coil, that is, between the rotating shaft and the wall portion of the support, the energy generated by the load can be absorbed, thereby preventing the first cylindrical coil from being damaged.

[0034] The toilet device according to the fourth aspect can prevent the second cylindrical coil from being damaged under the action of an external load.

[0035] For the toilet device according to the fifth aspect, since the resin material has better elasticity, it can better absorb external loads.

[0036] For the toilet device according to the sixth aspect, considering that the first cylindrical coil may be connected to the power receiving unit through a cable, when the user sits on the seat, the cable may be damaged under the action of the load. Therefore, by forming a first chamber in the first main body portion, at least a part of the cable can be arranged in the first chamber, so that these cables can be prevented from being damaged.

[0037] For the toilet device according to the seventh aspect, considering that the second cylindrical coil may be connected to the power supply unit through a cable, there is a possibility that the cable may be damaged under the action of the load. Therefore, by forming a second chamber in the second main body portion, at least a part of the cable can be arranged in the second chamber, so that these cables can be prevented from being damaged.

[0038] The toilet device according to the eighth aspect can achieve a rotatable connection between the seat ring and the support with a simple structure.

[0039] The toilet device according to the ninth aspect can make the toilet device have a heating function.

[0040] The toilet device according to the tenth aspect can prevent the cleaning agent or water from adhering to the coil and can prevent the user from directly contacting the coil. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In the present invention, the term "toilet" refers to the entire cleaning device for flushing the toilet, for example, including a seat body with a dirt receiving groove, a toilet seat cover (which can be an electronic seat cover, that is, a smart seat cover, but can also be a traditional seat cover), various pipelines, wires, connectors, fittings, etc. for the toilet. It can be understood that the toilets finally made from the toilet body of the present invention also cover various types, for example, smart toilets, siphon toilets, and various types of traditional toilets are all within the scope of the present invention. It should be noted that, for the sake of simplicity of description, the constituent elements in the toilet device that are not related to the innovative points of the present invention are omitted, for example, the toilet bowl and the water tank are omitted.

[0050] Figure 1 This is a perspective exploded view of the constituent elements of the toilet device S according to an embodiment of the present invention, Figure 2 This is a top view of the constituent elements of the toilet device S according to an embodiment of the present invention, Figure 3AIt is a side view of a toilet seat in a raised state and a support body supporting the toilet seat in a toilet device according to an embodiment of the present invention. Figure 3B It is a side view of a toilet seat in a lowered state and a support body supporting the toilet seat in a toilet device according to an embodiment of the present invention. Figure 4 is Figure 3B A cross-sectional view taken along line B-B of the portion enclosed by the circle A shown in. As Figures 1 - 4 shown, the toilet device S of the present embodiment includes a toilet seat 1, a support body 2, a power supply unit 3, a first cylindrical coil 4 and a second cylindrical coil 5 constituting a pair of working coils, a power receiving unit 6, a heating device 7, a first coil fixing member 8, a second coil fixing member 9, a first load absorbing member 10, a second load absorbing member 11, a connection assembly 12, a drive motor 13, and a rotating member 14.

[0051] The toilet seat 1 includes a seat portion 1A and a pair of hinge support portions 1B. Among them, the seat portion 1A is the part where the user of the toilet sits, and the pair of hinge support portions 1B are the parts connected to the support body 2 in such a way that the toilet seat 1 can rotate. For the convenience of description, the hinge support portion on the left side among the pair of hinge support portions 1B is called the left hinge support portion 1B1, and the hinge support portion on the right side is called the right hinge support portion 1B2. An electric power receiving unit 6 and a heating device 7 are arranged inside the seat portion 1A of the toilet seat 1. The heating device 7 is a component that heats the seating surface of the seat portion 1A. For example, it is an induction heating type device, including a sheet-shaped heating element provided on the back surface of the seating surface, an induction coil provided below the heating element, and a heat insulating layer filled between the heating element and the induction coil. Under the action of the induction coil, an eddy current is generated in the heating element to make the heating element 17 emit heat, so that the seating surface is quickly heated up. However, the heating device 7 is not limited to the induction heating type, and it can also be a planar electric heater. The electric power receiving unit 6 receives the power supply from the power supply unit 3 under the action of the electromagnetic induction described later between the first cylindrical coil 4 and the second cylindrical coil 5, and supplies the received power to the heating device 7, a seat-side controller (not shown), and a pressure sensor (not shown). The seat-side controller controls the actions of each component on the seat side (for example, the pressure sensor, the electric power receiving unit 6, etc.). The pressure sensor is a sensor that senses whether a user is sitting. When the pressure sensor senses the presence of a user, it sends a heating signal to the electric power receiving unit 6 so that the electric power receiving unit 6 supplies power to the heating device 7. However, the type of the sensor is not limited to the pressure sensor, and other types of sensors can be used as long as they can sense the presence of a user. The pair of hinge support portions 1B including the left hinge support portion 1B1 and the right hinge support portion 1B2 are the parts protruding from the seat portion 1A toward the support body 2 side. Through holes are respectively formed in the left hinge support portion 1B1 and the right hinge support portion 1B2 for the first flange portion 8B of the first coil fixing member 8 and the connecting component 12 to pass through.

[0052] The first coil fixing member 8 includes a first main body 8A and a first flange 8B. By arranging the first main body 8A inside the left hinge support 1B1 and inserting the first flange 8B into the through hole of the left hinge support 1B1 and the through hole formed in the left side wall of the support body 2, the left hinge support 1B1 of the toilet seat 1 is connected to the left side wall of the support body 2. In addition, in the present embodiment, the first flange 8B is cylindrical and can act as a rotating shaft. The first main body 8A is a block-shaped part, and preferably a first chamber is formed inside it. Specifically, considering that the first cylindrical coil 4 may be connected to the power receiving unit 6 through a cable, the cable may be damaged under the action of the load when the user sits down. For this reason, by forming the first chamber in the first main body 8A, at least a part of the cable can be arranged in the first chamber, so that the cables can be prevented from being damaged. However, it should be noted that the first main body 8A is not a necessary part and can also be omitted. In this case, the first coil fixing member 8 is substantially the first flange portion 8B that functions as a rotating shaft. Figure 4 As shown, a coil fixing through hole is formed penetratingly in the first body portion 8A and the second flange portion 8B, and the first cylindrical coil 4 is inserted and fixed in the coil fixing through hole.

[0053] Furthermore, a first load absorbing member 10 is disposed radially outside the first flange portion 8B. The first load absorbing member 10 is a member for absorbing the load generated when the user sits down, and is formed of an elastic material such as a resin material. Specifically, when the user sits down on the seat portion 1A of the toilet seat 1, the connection portion between the pair of hinge support portions 1B of the toilet seat 1 and the support body 2 is deformed under the load generated by the user's weight, which may cause damage to the first flange portion 8B and the first cylindrical coil 4 fixed to the first flange portion 8B. In order to avoid this, as shown in FIG. Figure 4 As shown in the figure, the first load absorbing member 10 having an annular shape and elasticity is arranged along the entire circumference of the radially outer side of the first flange portion 8B. When a load is generated in the connection portion due to the user sitting down, the first load absorbing member 10 is elastically deformed to absorb the energy generated by the load. More specifically, the first load absorbing member 10 is interposed between the first flange portion 8B functioning as a rotation axis and the left side wall portion of the support body 2 in the circumferential direction.

[0054] Also, in the present embodiment, the first load absorbing member 10 is disposed radially inside the second load absorbing member 11. In other words, the second load absorbing member 11 for also absorbing an external load is disposed radially outside the first load absorbing member 10. Specifically, the second load absorbing member 11 is circumferentially interposed between the left side wall portion of the support body 2 and the second cylindrical coil 5, and is also formed of an elastic material such as a resin material. In the present embodiment, the second cylindrical coil 5 is disposed in the through hole of the left side wall portion of the support body 2, and most of the second load absorbing member 11 is also located in the through hole and between the through hole wall portion and the second cylindrical coil 5 as shown in Figure 4 and the remaining small portion protrudes leftward from the through hole and is located radially outside the first load absorbing member 10 and is in close contact with the first load absorbing member 10. Above, the arrangement of the second load absorbing member 11 is formed on the premise that the first load absorbing member 10 is formed outside the through hole of the left side wall portion of the support body 2, but is not limited thereto. For example, the first load absorbing member 10 may partially extend into the through hole of the left side wall portion of the support body 2. In such a case, the second load absorbing member 11 may be entirely disposed in the through hole as long as it is located radially outside the first load absorbing member 10 and is in close contact with the first load absorbing member 10. In this way, the first flange portion 8B of the first main body portion 8, the first load absorbing member 10, and the second load absorbing member 11 together constitute a hinge assembly, in which the first flange portion 8B functions as a rotating shaft, and the first load absorbing member 10 and the second load absorbing member 11 also function as bearings.

[0055] The first cylindrical coil 4 and the second cylindrical coil 5 constitute a pair of electromagnetic induction type coil pairs. As described above, the first cylindrical coil 4 is fixed to the first coil fixing member 8 by partially inserting into the coil fixing through hole formed in the first coil fixing member 8. On the other hand, the second cylindrical coil 5 is disposed in the through hole formed in the left side wall portion of the support body 2 as described above. In the present embodiment, both the first cylindrical coil 4 and the second cylindrical coil 5 are formed in a cylindrical shape, however, the diameter of the second cylindrical coil 5 is larger than the diameter of the first cylindrical coil 4. Thus, as shown in Figure 4As shown, the second cylindrical coil 5 surrounds at least a part of the first cylindrical coil 4 from the outside. However, it should be noted that the mutual arrangement relationship between the first cylindrical coil 4 and the second cylindrical coil 5 is not limited to this. It is also possible that the diameter of the first cylindrical coil 4 is larger than that of the second cylindrical coil 5, so that the first cylindrical coil 4 surrounds at least a part of the second cylindrical coil 5 from the outside. The first cylindrical coil 4 is electrically connected to the power receiving unit 6 by wired or wireless means to transfer the power generated and flowing in the first cylindrical coil 4 to the power receiving unit 6. Specifically, when the first cylindrical coil 4 is electrically connected to the power receiving unit 6 by wire through a cable, the current generated and flowing in the first cylindrical coil 4 is transferred to the power receiving unit 6 via the cable. On the other hand, when the first cylindrical coil 4 is electrically connected to the power receiving unit 6 wirelessly, a corresponding induction coil is arranged in the power receiving unit 6, and electromagnetic induction is generated between the first cylindrical coil and the induction coil, so that the required current is generated in the induction coil. The second cylindrical coil 5 is also electrically connected to the power supply unit 3 arranged in the support 2 by wired or wireless means. The specific situation is similar to that of the first cylindrical coil 4, so the repeated description is omitted here.

[0056] Next, taking the case where the first cylindrical coil 4 is electrically connected to the power receiving unit 6 in a wired manner and the second cylindrical coil 5 is electrically connected to the power supply unit 3 in a wired manner as an example, the operating principle of power transmission based on the first cylindrical coil 4 and the second cylindrical coil 5 will be described. The current from the power supply unit 3 is input to the second cylindrical coil 5 through a cable. The current flows in the second cylindrical coil 5 to generate a magnetic field. This magnetic field acts on the first cylindrical coil 4 located radially inside the second cylindrical coil 5, causing a current to be generated in the first cylindrical coil 4. This current is output to the power receiving unit 6 via the cable. As described above, in the prior art, a pair of planar coils are usually used, with the two facing each other at an interval in a direction perpendicular to the coil plane, and wireless power transmission is performed through electromagnetic induction between the two. However, the area of the planar coil is relatively large, requiring a large configuration space. When the available space is narrow, it is difficult to configure, which also limits the configuration of the heating device. In addition, it is also difficult to stably maintain the distance between the planar coils. Therefore, in the present embodiment, a pair of cylindrical coils are used, and one of them surrounds at least a part of the other from the outside. In this way, for the same coil, compared with the planar coil, the radial dimension of the cylindrical coil is significantly reduced, and the restriction on the configuration space is significantly reduced. Moreover, different from the configuration in which the planar coils face each other at an interval in a direction perpendicular to the coil plane, in the present embodiment, the pair of cylindrical coils at least partially overlap in this direction, and one surrounds at least a part of the other from the outside. In this way, the power transmission rate can be increased, and the effective utilization rate of power supply can be improved.

[0057] The second coil fixing member 9 is a member for fixing the second cylindrical coil 5, and includes a second main body portion 9A and a second flange portion 9B. The second flange portion 9B is inserted and disposed in the through hole of the left side wall portion of the support body 2. More specifically, the second flange portion 9B is clamped between the second load absorbing member 11 and the wall portion of the through hole in the through hole, so that the second cylindrical coil 5 is fixed by the second flange portion 9B with the second load absorbing member 11 interposed therebetween. The second main body portion 9A is a block portion, and preferably has a second chamber formed therein. Specifically, considering that the second cylindrical coil 5 may be connected to the power supply unit 3 through a cable, and the cable may be damaged under the action of load. Therefore, by forming the second chamber in the second main body portion 9A, at least a part of the cable can be disposed in the second chamber, so that these cables can be prevented from being damaged. However, it should be noted that the second main body portion 9A is not an essential part and may be omitted.

[0058] As Figure 4As shown, a drive motor 13 and a rotating member 14 are also disposed inside the support body 2. The drive motor 13 is powered by the power supply unit 6 or other power supply parts and operates. It is connected to the rotating member 14 to drive the rotating member 14 to rotate. One end of the rotating member 14 is connected to the drive motor 13, and the other end cooperates with the connection assembly 12 in the following locked state. The connection assembly 12 includes a locking member 12A and a mating member 12B. Among them, the locking member 12A is inserted and disposed in the through hole of the right hinge support portion 1B2, and a part of the mating member 12B is disposed in the through hole, and the other part is disposed in the through hole of the right side wall portion of the support body 2. The locking member 12A can move forward and backward in the through hole of the right hinge support portion 1B2 by rotation or pressing, so as to be in the locked state and the unlocked state respectively. The mating member 12B is configured to cooperate with or disengage from the rotating member 14 according to whether the locking member 12A applies a force to it. Specifically, when the locking member 12A moves forward toward the support body 2 in the through hole and presses the mating member 12B, the mating member 12B also moves forward toward the support body 2 and cooperates (for example, engages) with the rotating member 14, thereby constituting the locked state. In this locked state, when the rotating member 14 rotates under the drive of the drive motor 13, since the mating member 12B is engaged with the rotating member 14, the mating member 12B also rotates together. As a result, the toilet seat 1 is lifted upward or lowered downward. On the other hand, when the locking member 12A retreats in the through hole in the direction opposite to the support body 2 side, the pressing force acting on the mating member 12B is eliminated. Thus, the cooperation between the mating member 12B and the rotating member 14 is released, and the mating member 12B is separated from the rotating member 14, thereby constituting the unlocked state. In the unlocked state, the right hinge support portion 1B2 and the support body 2 become separable, so that the toilet seat 1 can be removed from the support body 2.

[0059] Figure 5 Fig. shows a perspective view of the process of removing the toilet seat from the support body when the locking member 12B is a rotary member. Figure 5 In A of, since the locking member 12B is in the locked state and the mating member 12B is engaged with the rotating member 14, the toilet seat 1 cannot be separated from the support body 2. In Figure 5 In B of, the locking member 12B is rotated so that the locking member 12B retreats in the direction opposite to the support body 2 side. Thus, it changes from the locked state to the unlocked state, and the mating member 12B is separated from the rotating member 14. Then, in Figure 5 In C of, the right hinge support portion 1B2 of the toilet seat 1 is separated from the support body 2. Then, in Figure 5In D, the left hinge support portion 1B1 is also separated from the support body 2 by pulling out the first flange portion 8B of the first coil fixing member 8 from the through hole in the left side wall portion of the support body 2. Thus, the separation of the toilet seat 1 from the support body 2 is completed.

[0060] In the toilet device S according to the present embodiment, by using a pair of cylindrical coils, one of them is arranged in the toilet seat and the other is arranged in the support body, and one of them surrounds at least a part of the other from the outside, it is possible to prevent the energized part from being exposed outside, thereby preventing the user from touching the energized part and getting an electric shock. In addition, compared with using a pair of planar coils opposed to each other at intervals in a direction perpendicular to the coil plane, using a pair of cylindrical coils can greatly reduce the requirement for the arrangement space and improve the power transmission efficiency. In this way, it is possible to provide a toilet device S that is easy to arrange and disassemble, has high safety, and has higher power transmission efficiency.

[0061] In addition, although not shown in the figure, in order to prevent the cleaning agent or water from adhering to the coil and prevent the user from directly contacting the coil, preferably, the toilet device S further includes a resin housing that covers at least one of the first cylindrical coil 3 and the second cylindrical coil 5 from the outside.

[0062] The foregoing description has set forth numerous features and advantages, including various alternative embodiments, as well as details of the structure and function of the apparatus and methods. The intention herein is illustrative and not exhaustive or restrictive.

[0063] It will be apparent to those skilled in the art that various modifications can be made within the full scope indicated by the broad general meaning of the terms expressed by the appended claims, particularly in terms of structure, materials, elements, components, shape, size, and arrangement of components, including combinations within the scope of the principles described herein. To the extent that these various modifications do not depart from the spirit and scope of the appended claims, it is intended that they also be subsumed therein.
