Description

  The present invention relates to a heating toilet seat device equipped with a toilet lid having a heat insulating function.

  Conventionally, as this type of heated toilet seat device, in order to enhance the heat retaining effect of the toilet seat with a built-in heating means, the toilet lid covering the toilet seat has a hollow double structure, and a heat insulating material is accommodated in the hollow portion to provide a heat insulating effect. It is the structure to obtain. Since the toilet lid becomes thicker due to the double structure of the toilet lid, the detection area of the human body detection sensor and the seating detection sensor that operate in the state where the toilet lid is opened interferes with a part of the toilet lid, so the sensor function is Since there is a concern about being obstructed, the thickness of the central portion of the face lid is made thinner than the surrounding thickness, so that the detection area and the toilet lid do not interfere with each other (see, for example, Patent Document 1). .

  FIG. 7 shows a conventional heating toilet seat device described in Patent Document 1. In FIG. As shown in the figure, a toilet seat 2 and a toilet lid 3 are pivotally supported by a main body 1 of the heating toilet seat device, and the toilet lid 3 has a double structure of a toilet lid main body 4 and a bottom plate 5. In the meantime, the heat insulating material 6 is accommodated. The thickness of the toilet lid 3 is formed such that the thickness T1 of the central portion is thinner than the peripheral thickness T2, and the toilet lid 3 and the detection area S of the sensor do not interfere with each other.

JP 2010-178923 A

  However, in the conventional configuration, when the toilet lid is opened, the toilet lid and the detection area of the sensor do not interfere with each other. However, when the toilet lid is closed, the toilet lid enters the detection area of the sensor. Incorrect detection of human body detection or seating detection will occur.

  In order to eliminate such erroneous detection, a separate toilet lid opening / closing sensor for detecting the opening / closing state of the toilet lid, such as an angle sensor for detecting the opening / closing angle of the toilet lid, is provided. It is essential to stop the functions of the detection sensor and the seating detection sensor or to cancel the received detection signal.

  It is structurally or costly to install a toilet lid opening / closing sensor that is essential for implementing the above configuration. In particular, products with a popular rank, which generally have only a seating detection sensor, have a high cost increase ratio, and there is room for improvement in terms of structure and cost.

  The present invention has been made in view of the above-described conventional problems, and enhances the heat insulating effect of the toilet lid to improve energy saving. In the closed state of the toilet lid, the detection area of the seating detection sensor and the toilet lid An object of the present invention is to provide a low-cost heating toilet seat device that suppresses erroneous detection by eliminating the interference.

In order to solve the above-described conventional problems, the heating toilet seat device of the present invention includes a main body that is placed and fixed on a toilet bowl, an inverted position that is pivotally mounted on the main body and has a substantially horizontal seating surface, and a seating surface that is substantially horizontal. A toilet seat with a built-in toilet seat heater that can rotate between a vertical standing position and that heats the seating surface, a closed position that is pivotally mounted on the main body and covers at least the upper surface of the toilet seat in the inverted position, and the upper surface of the toilet seat A toilet lid that is rotatable between an open position and a seating detection sensor that is disposed on a front surface of the main body and detects a human body seated on the seating surface, wherein the toilet lid is pivotally mounted on the main body. A toilet lid body, and an inner surface member of the toilet lid body that is disposed to face the inner surface of the toilet lid body with a gap at least partially, and in a state where the toilet lid is in a closed position, The toilet lid inner surface member is not arranged in the above.

  Thereby, it becomes possible to suppress heat dissipation of the toilet seat by the heat insulating effect by the double structure of the toilet lid, and energy saving can be improved.

  In addition, even if the seating detection sensor is always kept in the operating state, it is possible to reliably detect the human body seated on the toilet seat in the open state without erroneous detection in the closed state of the toilet lid. Reliability can be improved. Moreover, it is not necessary to install another sensor for detecting the open / closed state of the toilet lid, and an increase in cost can be suppressed.

  As described above, it is possible to provide a heating toilet seat device with high energy saving and reliability at a low cost.

The shape of the bearing portion insertion hole 425 is formed in a shape corresponding to the left and right bearing portions 414 having different outer shapes, and can be inserted only in a predetermined direction. The bearing portion 414 can be attached to and detached from the bearing portion insertion hole 425 by deforming the support portion 422 using the elasticity of the resin material.

  As shown in FIG. 5, a recessed portion 426 that is recessed upward is formed at the center of the flat portion 421, and the recessed portion 426 is formed from the rear end of the flat portion 421 to the vicinity of the front end.

  As shown in FIG. 3, when the toilet lid main body 410 and the toilet lid inner surface member 420 are assembled, a small gap 401 of 1 mm or less is formed between the toilet lid main body 410 and the toilet lid inner surface member 420 in the recessed portion 426. However, there is a part that abuts partly due to variation in the shape of the member. Further, on both sides of the recessed portion 426, a gap 401 having a large dimension of about 3 cm at the maximum is formed between the toilet lid main body 410 and the toilet lid inner surface member 420.

The buffer member 430 is a member that is molded from a thermoplastic elastomer resin (TPE), which is a soft resin material having elasticity, and is a member that relieves an impact when the toilet lid 400 and the toilet seat 300 come into contact with each other.

The leg portion 431 is configured not to be easily removed by press-fitting into the support portion 422. Further, the contact portion 432 is formed to have a size larger than the leg portion 431. Accordingly, the toilet lid main body 410 and the toilet lid inner surface member 420 are fixed by the contact portion 432 and are not easily detached.

  As shown in FIGS. 6 and 7, the toilet lid 400 is assembled by disposing a toilet lid inner surface member 420 on the inner surface of the toilet lid main body 410 and using the elasticity of the resin material in the bearing portion insertion hole 425 in the bearing portion 414. , The rear portion of the toilet lid inner surface member 420 is engaged with the toilet lid main body 410. Further, by inserting the holding portion 413 into the holding portion insertion hole 424 and press-fitting the buffer member 430 into the holding portion 413 from above, the front portion of the toilet lid inner surface member 420 is moved by the contact portion 432 of the buffer member 430. Engaged with the toilet lid body 410.

  As shown in FIGS. 2 and 3, when the toilet lid main body 410, the toilet lid inner surface member 420, and the buffer member 430 are assembled, the outer periphery of the toilet lid inner surface member 420 and the inner surface of the toilet lid main body 410 are completely in contact with each other. Instead, a slit-shaped opening of 1 mm or less is formed in at least a part. The opening formed on the outer periphery of the toilet lid inner surface member 420 is such that air in the gap 401 can be prevented from leaking to the outside, and the gap 401 formed between the toilet lid main body 410 and the toilet lid inner surface member 420. Is close to sealing.

  Further, the reinforcing rib 423 formed on the toilet lid inner surface member 420 also has an action of suppressing the flow of air inside the gap 401, so that the heat insulating effect of the gap 401 can be improved.

  The toilet lid 400 in the assembled state is inserted into the rotating shaft (not shown) of the main body 200 using the elasticity of the resin forming the toilet lid 400, so that the toilet lid 400 is 200 is rotatably installed.

<3> Operation and Action of Heating Toilet Seat Device In a standby state where the heating toilet seat device is not used, the toilet seat is normally left in a state where the toilet lid is closed as shown in FIGS. In the standby state, the toilet seat 300 is kept warm by a built-in toilet seat heater at a standby temperature of 29 to 31 degrees, which is a temperature that does not feel cold even when the seating surface 310 is seated.

  The toilet lid 400 covering the upper part of the toilet seat 300 has a double structure of the toilet lid main body 410 and the toilet lid inner surface member 420, and the toilet lid 400 disposed above the toilet seat 300 as shown in FIG. On both side portions, a gap 401 is formed between the toilet lid main body 410 and the toilet lid inner surface member 420, and the heat insulating effect is high.

  The seating detection sensor 210 is always maintained in an operating state capable of detecting a human body. As shown in FIG. 2, infrared rays are emitted forward from the main body 200, and a range indicated by hatching in the figure is a detection area W.

  The toilet lid inner surface member 420 of the toilet lid 400 has a configuration in which the detection area W and the toilet lid inner surface member 420 do not interfere with each other because the concave portion 426 is formed at the center, and the toilet lid 400 is erroneously detected as a human body. In the state where the toilet lid 400 is closed, the seating detection sensor 210 is not detected.

  In the state where seating is not detected, the control unit is configured to cancel the operation signal of the operation switch 230 such as a cleaning unit used at the time of sitting. For example, even if the operation switch 230 of the cleaning unit is operated, It has a configuration in which an erroneous operation such as ejection is not performed.

When the user opens the toilet lid 400 and sits on the toilet seat 300, the infrared rays emitted from the seating detection sensor 210 are reflected by the human body, and the seated detection sensor 210 receives the reflected light to detect the seated human body. It will be in the state of seating detection.

  When seating is detected, the control unit controls energization of the toilet seat heater, and performs a temperature-raising drive so that the temperature of the seating surface 310 is seated higher than the standby temperature and becomes a comfortable temperature of 29 to 37 degrees. . The heat insulation temperature can be changed stepwise by an operation switch 230 provided on the sleeve portion 220.

  Further, the standby temperature is also changed in conjunction with the change of the heat retention temperature. For example, when the temperature is set to 29 degrees, the standby temperature is set to 29 degrees, when the temperature is 33 degrees, the standby temperature is 30 degrees, and when the temperature is 37 degrees, the standby temperature is 31 degrees. Is set.

  In the seating detection state, the control unit drives each function such as the cleaning means of the heating toilet seat device based on the operation signal of the operation switch 230. Further, when the user stands up while the function is being driven and the seating detection sensor 210 finishes the seating detection, the control unit immediately stops the function being driven to ensure safety.

  After the seating detection sensor 210 finishes the seating detection and after a predetermined time has elapsed (3 minutes in the present embodiment), the control unit changes the energization pattern of the toilet seat heater and changes the temperature of the toilet seat 300 from the warming temperature to the standby temperature. Control to become.

  As described above, the heating toilet seat device 100 according to the present embodiment has a heat insulating effect due to the double structure in which the toilet lid 400 is provided with the gap 401 between the toilet lid main body 410 and the toilet lid inner surface member 420. In addition, since heat radiation from the toilet seat 300 can be suppressed with the toilet lid 400 closed, a high energy saving effect can be obtained.

  In addition, a recess 426 is provided at the center of the toilet lid inner surface member 420 so that interference between the toilet lid inner surface member 420 and the detection area W of the seating detection sensor 210 is eliminated while the toilet lid 400 is closed. Accordingly, it is possible to suppress erroneous detection of the seating detection sensor 210 without providing another sensor for detecting the open / closed state of the toilet lid 400, and it is possible to implement a highly reliable heating toilet seat device at low cost.

  Moreover, since the planar strength of the toilet lid inner surface member 420 can be increased by providing the recessed portion 426 in the toilet lid inner surface member 420, the thickness of the toilet lid inner surface member 420 can be reduced. The weight reduction of the inner surface member 420 can be realized.

  In addition, since the toilet lid body 410, the toilet lid inner surface member 420, and the buffer member 430 are all attached and detached using the elasticity of the resin material, assembly, maintenance, and recycling of the toilet lid 400 do not use tools. Can be easily implemented. Further, since the toilet lid main body can be shared with other products that do not use the toilet lid inner surface member, the member can be standardized.

  In addition, since an opening is provided at least in part between the outer periphery of the toilet lid inner surface member and the inner surface of the toilet lid body, even when the toilet lid 400 is assembled and washed with water, Since the accumulated water can be easily drained, it is easy to maintain and cleanliness can be easily maintained.

  In the present embodiment, the gap 401 formed by the toilet lid main body 410 and the toilet lid inner surface member 420 is configured to be used in a hollow state. However, the present invention is not limited to this, and at least a part of the gap 401 is used. It is good also as a structure which has arrange | positioned the heat insulating material.

  As described above, since the heating toilet seat device according to the present invention can improve the energy saving effect at low cost, it can be applied to other household appliances and the like having a heat retaining function.
