Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heated toilet seat device for heating the surface of a toilet seat.

[Prior art]

In recent years, a heated toilet seat device has become widespread in which the user can comfortably sit on the toilet seat and defecate by warming the surface of the toilet seat in advance even in low temperatures such as winter. A toilet seat 2 which is connected to a body case 5z as shown in FIG. 13 by a rotatable hinge 19 and has a hollow structure.
Inside the z, the voltage (A
C100V) is applied to store the toilet seat heating means 12, which heats up, and the main body case 5z is provided with a control section 5z for controlling the amount of heat generated by the toilet seat heating means 12. The main body case 5z and the toilet seat 2z are provided by an electric cord 13. The heating toilet seat device 1z, which cannot be removed by connection, is the mainstream, but in order to improve the cleaning property, in JP-A-5-237047, the inside of the hinge that rotatably connects the main body case and the toilet seat has a hollow structure, There has been proposed a warm air heated heating toilet seat device that warms the toilet seat by blowing and circulating warm air from the rear part of the toilet seat to the inside from the body case via the inside of the hinge.

[0003]

However, when warm air is blown from the rear part of the toilet seat to warm it, the air velocity of the warm air blown out from the hinge part suddenly increases because the cavity at the rear part of the toilet seat is wide. The surface temperature behind the toilet seat, which is near the opening, is intensively heated and reaches a high temperature.When the user sits down, the surface temperature from the center of the toilet seat to the buttocks and thighs rises almost from the tip side. I can't let you do it.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a heating toilet seat device that efficiently blows warm air into the toilet seat to warm the surface of the toilet seat.

[0005]

In order to solve the above-mentioned problems, the invention according to claim 1 is arranged in a blower fan for blowing air and in a blower duct for heating the air to generate warm air. A warm air heater, a main body case for housing the blower fan and the warm air heater, a blower port arranged on the front side surface of the main body case and communicating with the blower duct, and an internal portion arranged in front of the main body case. A hollow toilet seat, and a hollow blow-out duct that is inserted from the rear side surface of the toilet seat, allows warm air from the blower port to flow in from one end, and has the other end protruding in non-contact with the inner surface of the toilet seat. The heating toilet seat device is characterized by comprising: When an opening is provided on the rear side of the toilet seat and hot air is blown from there, the cavity behind the toilet seat has a large spread and the wind speed of the warm air drops sharply. Is heated intensively and reaches a high temperature state, and when the user sits down, the surface temperature of the tip side from the center of the toilet seat where the buttocks and thighs contact can hardly be raised. Therefore,
By inserting and arranging a hollow blowing duct that protrudes in a non-contact manner with the inner surface of the toilet seat from the rear side of the toilet seat, and blowing the warm air blown from the air outlet into the inside of the toilet seat through the blowing duct, It is possible to prevent the wind velocity of the warm air blown inside the toilet seat from rapidly decreasing. In particular, since the blow-out duct projects without contact with the inner surface of the toilet seat, it is possible to prevent the heat of the warm air flowing into the blow-out duct from the blower opening from being taken away by the rear portion of the toilet seat. As a result, uneven heat distribution behind the toilet seat can be suppressed and the tip side can be warmed from the center of the toilet seat. Therefore, when the user sits on the toilet seat, a sufficient feeling of heating can be obtained, and since burns due to high temperature can be prevented, safety is improved.

According to a second aspect of the present invention, the end face portion in the longitudinal direction of the opening and the depth direction of the opening with respect to the center point of the opening provided for excretion in the substantially central portion of the toilet seat is used. When the tangent line is the boundary line 1, the tip end portion of the blowing duct located inside the toilet seat is substantially the same as the boundary line 1 or is arranged closer to the tip end side of the toilet seat than the boundary line 1. The heating toilet seat device according to claim 1. Here, the longitudinal direction of the opening is the direction parallel to the direction of the thigh when the user sits on the toilet seat, and the depth direction of the opening is the back of the user when the user sits on the toilet seat. And the direction of the tip of the toilet seat means the direction in which the front of the user sits on the toilet seat. By arranging the tip end portion of the blowing duct located inside the toilet seat to be substantially the same as the boundary line 1 or arranged on the tip end side of the toilet seat from the boundary line 1, the amount of warm air toward the tip end direction of the toilet seat increases, As a result, the surface of the toilet seat on the tip side can be efficiently raised from the center of the toilet seat where the buttocks and thighs come into contact when the user sits down. Also, when warming the toilet seat by heat transfer from the warm air, the amount of heat taken away at the place where the warm air first contacts the toilet seat surface is large, so the angle of the warm air blown out from the outlet is parallel to the bottom of the toilet seat. It is desirable to arrange ducts.

The invention according to claim 3 is characterized in that the blow-out duct has a notched upper end portion.
The heating toilet seat device according to claim 1. When the tip portion of the blowing duct located inside the toilet seat is approximately the same as the boundary line 1 or is arranged closer to the tip end side of the toilet seat than the boundary line 1, by notching the tip upper surface portion of the blowing duct, the opening end surface is formed. The surface of the toilet seat in the back direction can also be warmed to warm the entire surface of the toilet seat on which the user sits.

According to a fourth aspect of the present invention, a heating toilet seat device according to any one of the first to third aspects is characterized in that a shielding plate extending from a side surface of the blowing duct toward the opening is provided inside the toilet seat. Is. When warm air is blown from the blowing duct and circulates inside the toilet seat, by providing a shielding plate inside the toilet seat from the side of the blowing duct to the inside of the toilet seat, the blowing direction of the warm air blown from the blowing duct is once inside the toilet seat. Since it is not hindered by the circulating hot air, it is possible to warm a predetermined place.

According to a fifth aspect of the present invention, the opening shape of the tip end portion of the blowing duct located inside the toilet seat is a flat rectangular shape. It is a heated toilet seat device. The following points must be taken into consideration when determining the opening shape of the tip of the blowing duct. The O-shaped toilet seat that is normally used is used from the back of the toilet seat (pointing to the end of the toilet seat that is behind the user when the user sits on the toilet seat) to the tip of the toilet seat (when the user sits on the toilet seat). Since the air passage becomes narrower toward the front of the person (pointing to the end of the toilet seat), efficiently warm the surface from the center of the toilet seat where the buttocks and thighs come into contact when the user sits down. Then, it is necessary to reduce the opening area so as not to reduce the wind speed as much as possible. If the opening area is too large, even if the amount of warm air blown from the blower opening is small, the tip of the toilet seat cannot be efficiently warmed.
Also, when trying to warm the toilet seat by increasing the speed of the warm air blown from the blowing duct, the flow of warm air is biased toward the outer peripheral surface of the toilet seat due to centrifugal force because the tip of the toilet seat is U-shaped, and as a result, , The inner surface of the toilet seat does not warm up to the proper temperature. Considering the above points, it is preferable that the opening shape of the tip end portion of the blowing duct is a flat rectangular shape capable of blowing warm air over a wide range and increasing the wind speed. Therefore, by making the width of the tip of the blowing duct as wide as possible and making the height as low as possible, even if the amount of warm air blown from the air outlet is small or you want to warm the toilet seat in a short time, The surface can be warmed and uneven temperature can be reduced.

According to a sixth aspect of the present invention, the shape of the opening of the blower opening is substantially the same as the shape of the opening of the rear end of the blowing duct located outside the toilet seat, and the center point of the opening of the blower opening is the same. The heating toilet seat device according to any one of claims 1 to 5, wherein a height and a lateral position of a center point of the opening of the blowing duct are substantially the same. Let S1 be the opening cross-sectional area of the blower opening and S2 be the opening cross-sectional area of the rear end portion of the blowing duct located outside the toilet seat.
If the shapes are too different, the warm air blown from the blower opening leaks to the outside of the blowout duct or entrains unheated air, so that the toilet seat cannot be heated efficiently. Therefore, if the opening shape of the blowing duct is rectangular, it is preferable that the shape of the blower opening is also rectangular and is substantially the same as the width and height of the blowing duct. In addition, even if the opening shape is almost the same, if the height of the air outlet arranged in the main body case and the height and lateral position of the blowing duct arranged behind the toilet seat are different, the flow of warm air is obstructed as in the above, and the efficiency is improved. We cannot often send warm air to the inside of the toilet seat. Therefore, it is preferable that the center point of the opening of the blower port and the center point of the opening of the blowing duct are arranged so that their heights and lateral positions are substantially the same. With such a configuration, even if the air outlet and the air outlet are not blown using a connecting member such as a hose, warm air can be efficiently blown inside the toilet seat to warm the toilet seat even when the main body case and the toilet seat are not in contact with each other. it can. Only by removing the hinge that rotates the toilet seat back and forth, no other member for connecting the main body case and the toilet seat is required, so that the toilet seat can be removed from the main body case and cleaned in a short time.

According to a seventh aspect of the present invention, a plurality of the air outlet ducts are arranged at a rear portion corresponding to an extension line of the toilet seat in the longitudinal direction, and a plurality of the air outlets are also provided. The heated toilet seat device according to any one of claims 1 to 6, wherein hot air is blown into the interior alternately. Here, the longitudinal direction of the toilet seat refers to the direction parallel to the direction of the thigh when the user sits on the toilet seat. When the longitudinal direction of the toilet seat is divided into left and right with the center point of the opening as the reference, for example, when the blowing duct is placed only in the rear part corresponding to the extension line on the right side of the toilet seat and hot air is blown from there, the toilet seat tip It is not possible to sufficiently warm the left side of the toilet seat because the heat of the warm air is gradually taken from the place where it collides with the wall surface and becomes a turbulent flow, and where it contacts the inner surface of the toilet seat. Therefore, by inserting and arranging blowout ducts at both rear parts corresponding to the extension lines on the right side and the left side of the toilet seat, hot air is blown alternately from both blowing ducts toward the tip direction of the toilet seat. Hot air is taken into the toilet seat from the outlet duct located on the rear of the right side, and heat is taken by the toilet seat from the outlet duct located on the left of the left side of the toilet seat, and the low temperature warm air is discharged to the outside of the toilet seat. Hot air is taken in from the rear-side air outlet duct, and low-temperature warm air is discharged to the outside of the toilet seat from the rear-side air outlet duct on the right side of the toilet seat.By repeating this alternately, mainly when the user sits down. The tip side can be efficiently and evenly warmed from the center of the toilet seat where the buttocks and thighs come into contact.

The invention according to claim 8 is the heating toilet seat device according to claim 7, characterized in that an exhaust port is provided in a substantially rear central portion of the toilet seat. By providing the exhaust port at the rear center of the toilet seat, the warm air blown from the blowing duct and passed through the tip of the toilet seat can be circulated to the rear portion of the toilet seat (the back side of the toilet seat from the boundary line 1). Therefore, it is not possible to raise the surface temperature of the rear part of the toilet seat to the same temperature as the tip part, but to the extent that the user does not feel cold when sitting down, for example, the temperature from the center part of the toilet seat to the tip part. Is about 38 ° C., the rear part of the toilet seat, which is almost never in contact with the skin of the user, can be heated up to about 20 ° C. on average. As described above, even if the entire toilet seat is not evenly heated, a sufficient heating feeling can be obtained and the power consumption can be reduced by mainly heating the portion on which the user sits. If approximately the same amount of warm air is blown out from both outlet ducts at the same time, even if you try to blow the warm air toward the toilet seat tip side with the tip of the outlet toward the toilet seat tip direction, the warm air will not be blown to the toilet seat tip. The flow of warm air changes toward the exhaust port provided in the substantially central portion. When warming the surface of the toilet seat, first, it is desirable to alternately blow hot air from the blowing duct to warm the tip portion from the center of the toilet seat, and then to blow warm air of approximately the same amount from the blowing duct to warm the rear portion of the toilet seat.

According to a ninth aspect of the present invention, there is provided a heating toilet seat device according to the seventh or eighth aspect, in which an opening / closing plate that allows ventilation only in the inner direction of the toilet seat is arranged in the ventilation passage of the blowing duct. Is. When hot air is blown into the toilet seat alternately from multiple outlet ducts located behind the toilet seat, and when it is sent to the outside from the exhaust port provided in the approximate center of the toilet seat rear, the air volume from one outlet duct is set to zero. If this happens, hot air will leak from there and the flow of warm air toward the exhaust port will be blocked, and power consumption will increase to warm the rear part of the toilet seat to an appropriate temperature. Therefore, by placing an opening / closing plate that allows ventilation only in the inner direction of the toilet seat in the ventilation duct of the blowing duct, warm air is blown only from the blowing duct on one side and warm air is not blown from the blowing duct on the other side. However, it is possible to prevent the warm air blown from the blowing duct on one side from leaking to the outside from the blowing duct on the other side, and it is possible to reliably blow the warm air to the exhaust port provided at the rear of the toilet seat.

According to a tenth aspect of the present invention, the heating air according to any one of the seventh to ninth aspects is characterized in that a plurality of hot air blown into the toilet seat is blown from the plurality of the blowout ducts. It is a toilet seat device. If approximately the same amount of warm air is blown out from both outlet ducts at the same time, even if you try to blow the warm air toward the toilet seat tip side with the tip of the outlet toward the toilet seat tip direction, the warm air will not be blown to the toilet seat tip. The flow of warm air changes toward the exhaust port provided in the substantially central portion. Therefore, when the user sits down and blows warm air of substantially the same volume from both blowing ducts, the warm air can be blown toward the exposed portion of the human body from the exhaust port provided at the substantially central portion. By providing an exhaust port on the surface of the toilet seat that the user does not block when sitting, warm air can be sent to the buttocks, waist, and back where the skin is exposed, and the exhaust port is located above the toilet bowl surface. By providing it on the back side of the toilet seat located at, the buttocks and local areas can be heated.

The invention according to claim 11 is the heating toilet seat device according to any one of claims 1 to 6, characterized in that an exhaust port is provided at the tip of the toilet seat. By providing the exhaust port at the tip of the toilet seat, the warm air blown from the tip of the air outlet duct toward the tip of the toilet seat can be blown from the back of the user's knees to the feet. By providing an exhaust port at the tip of the toilet seat, which corresponds to the extension of the tip of the blow-out duct, it is possible to blow warm air in a straight line, suppressing the temperature of the warm air from lowering and heating the human body with less power consumption. You can

A main body case 5a for accommodating the warm air heater 8a and the control section 11a, blower ports 7a and 7b arranged on the front side of the main body case 5a and communicating with the blower duct 10a, and the main body case 5a.
And a toilet seat 2a having a hollow interior. Then, the air duct 10a is arranged so that the air outlets 7a, 7b arranged on the front side surface of the main body case 5a communicate with each other.
Is connected, and the blower fan 6a and the warm air heater 8a are arranged in the ventilation passage, and the blower port 7 is provided depending on the rotation direction of the blower fan.
a or a warm air heater 8a from the blower port 7b to a predetermined temperature
The hot air heated by the blowout duct 9 arranged on the side surface of the rear portion corresponding to the extension of the toilet seat 2a in the longitudinal direction.
The air is blown into the inside of the toilet seat 2a via a and 9b. The tip ends of the blowing ducts 9a and 9b located inside the toilet seat 2a have the longitudinal direction of the opening 3a with respect to the center point of the opening 3a provided for excretion in the substantially central part of the toilet seat 2a, and the opening 3a of the opening 3a. When the tangent of the end face portion in the depth direction is the boundary line 1, the boundary line 1 is disposed so as to project toward the distal end side of the toilet seat 2 a. The blowing ducts 9a and 9b are not in contact with the toilet seat 2a except that the rear ends thereof are fixed to the toilet seat 2a, and the surroundings of the blowing ducts 9a and 9b located inside the toilet seat 2a and the toilet seat 2a. Since an air layer is formed between them, therefore, the air outlet duct 9a, 9b is different from the air outlet duct 9a and 9b in contact with the toilet seat.
The heat of the warm air flowing through the a and 9b becomes difficult to be transferred to the toilet seat, and when the tip of the toilet seat 2a is tried to be warmed up to a predetermined temperature, the toilet seat 2a
It is possible to prevent the rear side from getting hot. In this way, if the length from the rear end of the toilet seat 2a to the tip of the blowing ducts 9a and 9b is L1 and the length from the rear end of the toilet seat 2a to the boundary line 1 is L2, the blowing ducts should be L1 ≧ L2. By arranging it, it is possible to suppress a decrease in wind speed due to a pressure loss at the outlet of the blowout duct, and a large amount of warm air is directed toward the tip of the toilet seat 2a. As a result, when the user sits down, the buttocks and thighs are The surface of the toilet seat 2a on the distal end side can be efficiently lifted from the center of the toilet seat 2a with which it comes into contact.

When the width dimensions of the tip end portions of the blowing ducts 9a and 9b located inside the toilet seat 2a are W1 and the height dimension is H1, W1 is made as wide as possible and the height dimension H1.
Is made as low as possible and has a flat rectangular shape, so that the distance from the inner surface of the toilet seat 2a can be reduced and the wind speed can be widened even if the amount of warm air blown from the air outlet is small or if you want to warm the toilet seat in a short time. Since the hot air can be blown into the inside of the toilet seat by raising the temperature, the amount of heat transferred to the surface of the toilet seat 2a corresponding to the upper end of the outlet ducts 9a, 9b can be suppressed, so that the toilet seat surface can be efficiently warmed, Temperature unevenness can be reduced.

Further, the tip portions of the blowing ducts 9a and 9b located outside the toilet seat are also rectangular in shape with the width dimension W1 and the height dimension H1 in the same manner as above, and the body case 5a is correspondingly formed.
The opening shape of the air outlets 7a, 7b arranged on the front side surface is also a rectangular shape having a width dimension W2 and a height dimension H2, and the lengths thereof are W1 = W2, H1 = H2, respectively, and the blowout ducts 9a, 9
b and the positional relationship between the air outlets 7a and 7b facing it,
They are arranged on the rear side surface of the toilet seat 2a and the front side surface of the main body case 5a so that the heights and lateral positions of the respective center points are substantially the same. Therefore, the air outlets 7a and 7b and the air outlet duct 9a,
The flow of warm air is not obstructed even if air is not blown into each of the 9b using a connecting member such as a hose, and the warm air can be efficiently blown into the inside of the toilet seat to warm the toilet seat. Only by removing the hinge that rotates the toilet seat back and forth, no other member for connecting the main body case and the toilet seat is required, so that the toilet seat can be removed from the main body case and cleaned in a short time. In the present embodiment, the opening shape of the blowing duct is a flat rectangular shape, but other shapes such as a flat elliptical shape and a flat kamaboko shape matching the shape of the toilet seat ventilation passage are conceivable.

By alternately blowing hot air from the blowing ducts 9a and 9b into the inside of the toilet seat 2a at the timing shown in FIG. 3, when the user sits down, the buttocks of the buttocks and thighs mainly come into contact with each other. It is possible to efficiently and evenly heat the tip side from the center. In the present embodiment, a blower fan that rotates in both the forward and reverse directions is arranged in the blower duct to blow warm air from a plurality of blower ports.However, the blower fan that rotates in the forward direction and the blower fan that rotates in the reverse direction are blown. It may be placed in the duct to rotate each blower fan according to the blowing direction, or if you want to blow hot hot air from the blower opening, you can insert multiple blower fans that rotate in both forward and reverse directions. A warm air heater may be arranged in the air duct to heat each warm air heater in accordance with the air blowing direction. In this way, by arranging a plurality of blowing ducts on the rear side of the toilet seat and taking in hot air from the blowing duct on one side, the cooled hot air is discharged from the blowing duct on the other side, and the main body case is opened. By adopting the structure in which the hot air is circulated through, the heat exchange efficiency can be improved without the need to provide a dedicated exhaust port on the toilet seat.

When an attempt was made to warm the toilet seat by raising the temperature of the warm air blown from the blowing duct, the blowing duct and the constituent material of the toilet seat portion in contact with the blowing duct were required to have heat resistance, and the equipment etc. were damaged. Since there is a risk that the hot air is blown to the user at the time and there is a risk of being burned, it is preferable to blow warm air of about 50 to 70 ° C. over a wide range with a well-balanced wind speed in consideration of safety. Further, by making the material forming the blowing duct the same as the material forming the toilet seat, it is possible to integrally mold and simplify assembly, so that productivity is improved.

Considering the user's seating distribution, the air volume of the warm air blown from the air outlet is changed from position to position by changing the height direction of the opening shape of the blowing duct from the inner peripheral surface side of the toilet seat to the outer peripheral surface side. By changing the height, for example, by lowering the height from the inner peripheral surface side of the toilet seat to the outer peripheral surface side of the toilet seat, the inner peripheral surface side of the toilet seat can be further warmed. As another means of changing the amount of air blown from the tip of the blowing duct for each place,
A method of vertically arranging a plurality of wind direction indicators on the inner surface of the tip of the blowing duct located inside the toilet seat and gradually increasing or decreasing the interval between the wind direction indicators from the inner peripheral surface of the toilet seat to the outer peripheral surface of the toilet seat is given. To be

Not blown inside. Therefore, the left and right surfaces of the toilet seat 2b can be evenly heated by extending the blowing time in accordance with the power input to the warm air heater 8b and the rising characteristics. Then, when the blowing of warm air to the toilet seat 2b is stopped, the blower fan 6b is stopped after the voltage application to the warm air heater 8b is cut off, and the warm air heater 8b is destroyed or deteriorated, or the blower duct 10b is melted. It is desirable to prevent ignition.

Since the opening / closing plates 15a and 15b which allow ventilation only in the inner direction of the toilet seat 2b are arranged at the tips of the outlet ducts 9c and 9d located inside the toilet seat 2b, hot air is blown only from the outlet duct 9c. Even when the hot air is not blown from the blowing duct 9d, it is possible to prevent the warm air blown from the blowing duct 9c from leaking to the outside from the blowing duct 9d, and to the exhaust port 14a provided behind the toilet seat 2b. The warm air can be reliably sent.
In addition, the opening / closing plates 15c and 15d are provided at the tips of the air outlets 7c and 7d.
This is sanitary because it is possible to prevent urine from entering the inside of the main body case 5b through the air outlets 7c and 7d when a man sits on the toilet seat 2b and urinates.

Further, when the user sits on the toilet seat 2b and blows warm air of substantially the same volume from both blowing ducts 9c and 9d as shown in FIG. 8 (period t4), it is provided at the substantially central portion. Warm air can be blown from the exhaust port 14a toward the exposed part of the human body. By providing the exhaust port on the surface side of the toilet seat that the user does not block when sitting, warm air can be blown toward the waist or back where the skin is exposed to the outside air,
By providing the exhaust port on the back side of the toilet seat located above the bowl surface of the toilet bowl, the buttocks can be warmed.
