Description of the Invention: [Rhyme ^ Ming Hu Jin is old ^ 彻 5 ^ 冷页 起 ^] Technical Field The present invention relates to a toilet seat device for the toilet seat seating temperature control. C. Previous winter; 1 BACKGROUND ART Conventionally, such a toilet seat device has various functions for adjusting the temperature at which a human body directly contacts a temperature to an appropriate temperature so as not to cause discomfort to the human body. In addition, the temperature control method of the toilet seat seating portion allows the user to sit on the toilet seat without feeling uncomfortable even when the temperature is low in winter (refer to, for example, Patent Document 1). The toilet seat device described has a toilet seat temperature detecting mechanism that is disposed on the inner surface of the toilet seat and that can detect the temperature of the toilet seat, a room temperature detecting sensor that detects room temperature, a heating element that is disposed on the inner surface of the toilet seat, and heat control. The control unit for the energization of the body. In the above configuration, the control unit controls the energization of the toilet seat heating element based on the signal from the toilet seat temperature detecting means and the room temperature detecting sensor. Since the toilet seat temperature detecting mechanism is located in the hollow of the inner surface of the toilet seat, it is not easy to be cold because it is not in contact with the outside air. When the room temperature in the toilet is low, the temperature difference with respect to the actual sitting surface is relatively poor. & The room temperature detection sensor measures the room temperature' to correct the output of the toilet seat heater so that the toilet wire surface reaches the optimum temperature. Thereby, the user can seat in the barrel seat more comfortably. 3 201019877 Moreover, the configuration for controlling the amount of energization of the heating element of the toilet seat according to the room temperature is not disclosed in Patent Document 2, and the target value of the toilet seat temperature is set in multiple stages according to the seating state 4 of the toilet seat by the user. The constitution is disclosed in Patent Document 3. CITATION LIST Patent Literature Patent Literature 1: Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. - 29374 〇 参 C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C Dedicated, there will be a problem that the composition becomes complicated and the cost increases. Further, according to the toilet seat device of Patent Document 2, regardless of the condition of the user entering the room of the temple, it is necessary to keep the temperature of the toilet seat constant, and the power of the wire φ is wasted, and the expectation of energy saving in recent years cannot be achieved. In the toilet seat device of Patent Document 3, it is expected that a certain degree of energy saving can be achieved in order to set the target value of the toilet seat temperature in multiple stages depending on the user's visual use. However, even in the standby state of the longest state (for example, the user does not enter the toilet room, etc.), the environmental conditions of the temple are not taken into consideration to control the temperature of the toilet seat. Therefore, in actuality, it is possible to heat the toilet seat to a temperature higher than a value set to the standby state temperature according to environmental conditions, thereby generating wasted power consumption. 4 201019877 Therefore, an object of the present invention is to provide a warm toilet seat apparatus which can further reduce the power consumption when adjusting the temperature of the toilet seat without affecting the comfort of the toilet user. Further, another object of the present invention is to provide a simple and compact output of the toilet seat heater, thereby providing a high-precision and comfortable heating toilet seat apparatus at a low price. Means for Solving the Problem The toilet seat device of the present invention includes: a toilet seat having a seat portion, a heat generating body for heating the toilet seat; and a control unit for controlling electric power to the heat generating body The toilet seat temperature detecting mechanism is for checking the temperature of the toilet seat; the second temperature detecting mechanism is for detecting the temperature in the toilet room; and the seated intention detecting mechanism is for detecting the seated intention information person' The seating intention information indicates the user's intention to sit on the toilet seat; and the control unit controls the energization of the heating element in a standby state in which the seating intention detecting mechanism does not detect the seating intention information. The temperature of the toilet seat detected by the toilet seat temperature detection reaches the 骇 standby temperature set to the rotation temperature of the preceding material state, and when the seated detection mechanism detects the seated intention information, the control pair The heat generating body is configured to cause the toilet seat detected by the horse temperature detecting means to rise from the standby temperature at a predetermined speed to be higher than the standby temperature, and ❹ temperature presumed by the difficulty of Ma seated seated temperature range of _ 'and' based on the second temperature detected by the detecting means of the toilet to the change of the energized heat generation of the aforementioned standby state. Therefore, the toilet seat of the present invention can at least distinguish between the standby state and the state of the 201019877 seat and is controlled to reach a standby temperature which is different from each other in each state and a temperature within a seating temperature range suitable for seating, and thus It can reduce the power consumption caused by the heating element. Further, in the standby state of the longest-term state, the energization of the heating element can be changed depending on the temperature in the toilet room, so that power consumption can be further reduced, and further energy saving can be achieved. Further, the control unit may be configured to reduce the electric power applied to the heat generating body when the indoor temperature of the hall is relatively high in the standby state. Therefore, when the indoor temperature of the hall is relatively high and the amount of heat released from the toilet seat is relatively small, the standby temperature can be maintained even when the temperature of the heat generating body is reduced when the temperature in the toilet room is low, so that the power consumption can be reduced. Further, the aforementioned predetermined speed may be 0.5 to 5 [grams per second]. The heating rate of the toilet seat is determined by a toilet composition such as the heating capacity of the heater and the heat capacity of the toilet portion heated by the heater. In addition, according to the temperature rise temperature, the user's intention information for the seat detected by the seated intention detecting means is raised from the standby temperature to the time when the seat is actually seated (according to the experiment obtained by the inventor, etc., It takes about 6 seconds from entering the toilet to seating. It can be heated to a temperature sufficient for seating (according to the experiments of the inventors, etc., the temperature that does not feel cold when seated is 29. 〇. Also, As long as there is such a heating capacity, the standby temperature can be set lower, so in the summer when the ambient temperature is high, energy saving can be achieved without standby power supply. The human detecting mechanism that detects the user entering the toilet room is used. The possibility that the user can sit on the toilet seat is high, and the period of 201019877 is ensured to be in the actual seating period. χ, by taking a seat It is ensured that the long-term, even from the lower standby temperature, can be raised to the range of the seating temperature range. Therefore, the standby temperature can be set lower, so the standby state can be further reduced. The consumption of electricity.

以下，一面參考圖式一面說明本發明之實施形態。而， 本發明並未受限於本實施形態。 (實施形態1) <ι>馬桶座裝置之外觀 第1圖為本發明實施形態1之馬桶座裝置的立體圖，第2 圖為概略構成圖，第3圖為同實施例之馬桶座的局部平面 圖，第4圖為馬桶座殼體上部之要部剖面圖。 如第1圖所示’馬桶20上面安裝有本體21，且馬桶座22 及馬桶蓋23可自由旋動地設置於該本體21。 本體21之扶手部設有紅外線感測部24，以接收來自操 作遙控器（未圖示）及人體檢測部（就座意向檢測機構)25之 紅外線訊號。人體檢測部25由例如熱電感測器與紅外線發 光部構成，當檢測出廁所空間有人體存在時，會傳送紅外 線訊號(就座意向檢測訊號）。該紅外線訊號可視為一表示使 用者具有就座於馬桶座22之意向而進入廁所室的訊號，因 此’可以高準確率檢測使用者對馬桶座22之就座意向。 又’本體21之上面設有顯示LED280。該顯示LED280 為通知馬桶座22之昇溫狀態的通知機構，在馬桶座開始昇 溫後立刻開始閃爍，而在雖就座於馬桶座22但仍未昇溫至 不冷之溫度以上時會連續亮燈，通知使用者馬桶座22之昇 溫狀態。 如第2、3圖所示’馬桶座22係利用將合成樹脂製的上 下2個構件在各自之内周緣及外周緣融化接合而形成殼體 9 201019877 26 ’且構造成其内部具有可阻止水等滲入之密閉空洞部27。 上述空洞部27之内部設有輻射反射板28及輻射型發熱 體之燈式加熱器29 ’該輻射反射板28係與馬桶座22之就座 部相對向’且將鋁板進行鏡面加工者。輻射反射板28之端 部具有整個外周朝向上方之彎折部，可利用該彎折部使來 自燈式加熱器29之熱輻射偏向，因此可提高遠離燈式加熱 器29之外周緣部及内周緣部之輻射密度，謀求對殼體26上 部之輻射分布的均勻化。該燈式加熱器29附近，設有與燈 式加熱器29電性串聯之恆溫器3〇及溫度保險絲31，可針對 萬一之不安全事態來防止溫度過度昇高。 上述燈式加熱器29係於玻璃管32内部貫通由鎢構成之 燈絲33而封入鹵氣體34來構成，隨著燈絲33之發熱重複一 形成鹵化鎢之齒循環反應，藉此防止燈絲33之消耗。藉該 作用可將熱容量非常小之燈絲33作為熱源，使輻射能急遽 上昇。該燈式加熱器29以具有橡膠墊圈35(彈性材料)之燈式 加熱器固定器36固定於輕射反射板28，且輻射反射板28以 橡膠腳(rubber leg)37固定於殼體26。馬桶座22之腳橡膠(leg rubber)39内設有微開關40所構成之就座檢測機構38 ,利用 對馬桶座22施加重量使開關開啟’藉此檢測使用者之就座。 如第4圖所示’殼體26係於使用透明聚丙烯樹脂材料而 利用射出成型構成之殼體本體41上面，形成大量含有碳黑 之輻射熱吸收層42 ’再於其上形成表面化妝層43，該表面 化妝層43為光阻隔層’可遮蔽由燈式加熱器29放射之所有 可視光，且考慮到表面硬度、埘藥品性、光澤度等。殼體 201019877 本體41係以平均厚度2.5mm形成透明聚丙烯樹脂材料，藉 此將熱輻射透過率設定於70%以上，且利用其剛性作為馬 桶座之構造矩體。又，形成之輻射熱吸收層42之厚度為 0.1mm，表面化妝層43之厚度為〇.2mm，這兩層可完全吸收 穿透设體本體41之賴射熱，且熱容量非常小，因此在瞬間 昇溫時，可完全遮蔽放射可視光。 殼體26内面所設之凹部嵌入有熱阻器44，該熱阻器44 與輻射熱吸收層42接觸，而與輻射熱吸收層42大致溫度相 同’因此可直接檢測輻射熱吸收層42之溫度。又，馬桶座 22之後部設有朝左右方向延伸之旋動軸45，馬桶座22可用 该旋動作45為基點在起立狀態與水平使用狀態間上下搖 動。該旋動軸45形成有電極46，與本體21之轴承部（未圖示） 一同構成馬桶座位置檢測機構47，可檢測馬桶座處於起立 狀態或處於就座使用之大致水平使用位置。本體21設有具 室溫檢測感測器48及計時部49之控制部50，室溫檢測感測 器48係作為用以檢測室溫之感測器，計時部49係計算因對 馬桶座22之燈式加熱器29通電而開始昇溫之時間點起的經 過時間。且，來自人體檢測部25、就座檢測機構38、熱阻 器44、馬桶座位置檢測機構47及室溫檢測感測器48之訊號 會分別傳達至控制部50 ’並根據這些訊號控制對燈式加熱 器29之通電，使保暖面之馬桶座22之上面溫度達到預定溫 度。 又’如第2圖所示’廁所室内設有室内暖氣部52，該室 内暖氣部52具有室内暖氣加熱器53與室内暖氣風扇54，可 11 201019877 進行廁所室内之加溫。 藉上述構成，使用者進入廁所時，人體檢測部25可檢 測使用者已進入廁所，並將該訊號透過紅外線感測部24傳 送至控制部50。此時，利用馬桶座位置檢測機構47之訊號 確認馬桶座22位於大致水平使用位置時，控制部50會開始 對燈式加熱器29通電。開始通電後，由燈絲33經玻璃管32 及輻射反射板28朝殼體本體41照射光，使燈光瞬間放射為 輻射能。又，輻射能在殼體本體41之内部雖然會一部份被 吸收或反射，但大半會穿透而有助於輻射熱吸收層42及表 _ 面化妝層43之昇溫。由於可如上將馬桶座22之就座部之採 暖面幾乎瞬間加溫，因此不需經常對加熱器通電，非常省 電。 ％ 又，本實施形態中，加熱馬桶座22之就座部的發熱體 、 係使用燈式加熱器29，但發熱體並不限於燈式加熱器29， 例如將使用琺瑯線之線狀加熱器黏著於馬桶座22之就座部 内面的構成亦可。斑瑯線之对熱性佳，可在十分短的時間 内將馬桶座22昇溫’且可確保電絕緣性及安全性。 <2>馬桶座裝置之通電程序 燈式加熱器29之驅動控制，係將驅動燈式加熱器29之 電力大致分為3種來改變而進行。 舉例言之，以第1溫度梯度使馬桶座22昇溫時，控制部 50以約1200W之電力來驅動燈式加熱器29(1200W驅動）。 若燈式加熱器29之電阻值為8.33Ω，對燈式加熱器29 施加交流100V時’會產生（100Vxl00V)+8.33Q=1200W之電 12 201019877 力。換言之，藉由於交流電源之全週期對燈式加熱器29流 通電流，產生1200W之電力。 又，以較第1溫度梯度略緩之第2溫度梯度使馬桶座22 昇溫時，控制部50以約500W之電力來驅動燈式加熱器 29(600W驅動）。 接著，要將馬桶座22之溫度保持一定時，控制部5〇以 約50W之電力來驅動燈式加熱器29(低電力驅動）。而，所謂 低電力驅動係指以遠低於1200W驅動及600W驅動之電力 (例如0W〜50W之電力）來驅動燈式加熱器29。 1200W驅動、600W驅動及低電力驅動之切換，係利用 控制部50之通電率切換電路控制由控制部50對燈式加熱器 29之通電而進行。 控制部50由未圖示之電源電路供給交流電流。故，控 制部50將根據通電率切換電路所給予之通電控制訊號的交 流電流，流動至燈式加熱器29。 第5圖顯示燈式加熱器29之驅動例及馬桶座22之表面 溫度變化。第5圖中，顯示馬桶座22之表面溫度與時間之關 係圖表、及驅動燈式加熱器29時之通電率與時間之關係圖 表。這兩個圖表之橫轴為共通之時間轴。 本實施形態中，設想使用者預先將加溫功能開啟，並 將馬桶設定溫度設定的較高（38°C)。 冬季等室溫較待機溫度之18°C低時，控制部50會調整 溫度來使馬桶座22之溫度到達18°C。如此，控制部50在人 體檢測部25檢測使用者進入為止之待機期間di間，進行燈 13 201019877 式加熱器29之低電力驅動，使馬桶座22之表面溫度到達18 C且固定。在該待機期間D1之低電力驅動下，會根據腐所 室内溫度來改變對燈式加熱器29之通電，藉此謀求降低消 耗電力，而這部分將於後述。 控制部50在時刻tl以人體檢測部25檢測出使用者進入 時’在衝擊電流降低期間D2間，進行600W驅動。而，該600W 驅動係為了充分降低衝擊電流而進行。燈式加熱器29在投 入電力前之燈絲33冷卻時會產生大衝擊電流。即使在此產 生之過電流為暫時性’對加熱器或電路也會造成負擔，對 壽命造成不良影響，雖可將對過電流有耐性之電子零件用 於電路設定，但會造成成本提高。本實施形態中，首先， 投入一半電力量來抑制衝擊電流，以控制影響產生。此時， 馬桶座22之表面溫度會以略緩之第2溫度梯度上昇。 而，在此雖將人體檢測部25檢測出使用者進入之時間 點作為時刻tl，但並未受限於此。舉例言之，可預先設置 一檢測出入廁所室時所開關之門打開與關閉的機構，並將 藉此檢測出門打開之時間點設定為時刻tl。如此檢測門打 開時，與使用人體檢測部25時相同，可檢測使用者似乎要 就座於馬桶座22之意向，因此藉將該時間點設為時刻u， 了將馬桶座22事先昇溫至適當溫度。此外，事先檢測使用 者就座意向之機構，亦可採用檢測馬桶蓋23之開啟動作（朝 上方開的動作）的機構、或檢測使馬桶座22朝下方搖動之動 作的機構等。 之後，控制部50在衝擊電流降低期間D2經過後之時刻 201019877 t2，開始燈式加熱器29之1200W驅動，在第1昇溫期間D3繼 續燈式加熱器29之1200W驅動。此時，馬桶座22之表面溫 度係以前述第1溫度梯度上昇。 在此，馬桶座22之表面溫度會急遽上昇。燈式加熱器 29之1200W驅動係進行到馬桶座22之表面溫度達預定溫度 (以下亦稱「使用初期目標溫度」，例如30。〇為止。當然， 該預定溫度（使用初期目標溫度）亦可為設定為加溫溫度之 溫度’但該溫度即使非充分達到加溫溫度而較低之溫度， 只要是使用者就座時不會感到冷而不舒服的最低界限溫度 (冷感界限溫度）以上即可。經發明者等所實施之被實驗者實 驗得知，該界限溫度約為29°C。換言之，使用初期目標溫 度只要是較待機溫度高，推測使用者就座於馬桶座22之就 座溫度範圍内（例如約29〜38°C)之溫度即可，其下限值可採 用上述冷感界限溫度（約29。〇。 如此，在第1昇溫期間D3中，馬桶座22之表面溫度可利

[Embodiment] 201019877 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiment. (Embodiment 1) <1> Appearance of Toilet Seat Device FIG. 1 is a perspective view of a toilet seat device according to Embodiment 1 of the present invention, FIG. 2 is a schematic configuration view, and FIG. 3 is a view showing a part of the toilet seat of the same embodiment. The plan view, Fig. 4 is a cross-sectional view of the main part of the upper part of the toilet seat housing. As shown in Fig. 1, the main body 21 is attached to the upper surface of the toilet 20, and the toilet seat 22 and the toilet cover 23 are rotatably provided to the main body 21. The armrest portion of the main body 21 is provided with an infrared ray sensing portion 24 for receiving an infrared ray signal from an operation remote controller (not shown) and a human body detecting portion (seat intention detecting mechanism) 25. The human body detecting unit 25 is composed of, for example, a thermal sensor and an infrared light emitting unit. When it is detected that there is a human body in the toilet space, an infrared signal (a seated intention detecting signal) is transmitted. The infrared signal can be regarded as a signal indicating that the user has entered the toilet room with the intention of sitting on the toilet seat 22, so that the user's intention to seat the toilet seat 22 can be detected with high accuracy. Further, a display LED 280 is provided on the upper surface of the body 21. The display LED 280 is a notification mechanism for notifying the temperature rise state of the toilet seat 22, and starts to blink immediately after the toilet seat starts to heat up, and continuously lights up when it is seated on the toilet seat 22 but has not heated up to a temperature that is not cold. The user is notified of the temperature rise of the toilet seat 22. As shown in Figs. 2 and 3, the toilet seat 22 is formed by melting and joining two upper and lower members made of synthetic resin on the inner periphery and the outer periphery of each of the outer casings to form a casing 9 201019877 26 'and configured to have water inside thereof. The sealed cavity portion 27 is infiltrated. The inside of the cavity portion 27 is provided with a radiation reflecting plate 28 and a lamp type heater 29' of a radiant heat generating body. The radiation reflecting plate 28 is opposed to the seating portion of the toilet seat 22 and mirror-processes the aluminum plate. The end portion of the radiation reflecting plate 28 has a bent portion whose entire outer circumference faces upward, and the bent portion can deflect the heat radiation from the lamp heater 29, thereby improving the distance from the outer periphery and the inside of the lamp heater 29. The radiation density at the peripheral portion seeks to uniformize the radiation distribution on the upper portion of the casing 26. In the vicinity of the lamp heater 29, a thermostat 3A and a temperature fuse 31 electrically connected in series with the lamp heater 29 are provided to prevent an excessive temperature rise in case of an unsafe situation. The lamp heater 29 is formed by penetrating a filament 33 made of tungsten inside a glass tube 32 and enclosing a halogen gas 34. The heat generation of the filament 33 repeats a ring reaction of forming a tungsten halide, thereby preventing the consumption of the filament 33. . By this action, the filament 33 having a very small heat capacity can be used as a heat source, so that the radiant energy rises sharply. The lamp heater 29 is fixed to the light-reflecting plate 28 by a lamp heater holder 36 having a rubber gasket 35 (elastic material), and the radiation reflecting plate 28 is fixed to the casing 26 by a rubber leg 37. A seat detecting mechanism 38 composed of a microswitch 40 is provided in the leg rubber 39 of the toilet seat 22, and the switch is opened by applying weight to the toilet seat 22 to thereby detect the seat of the user. As shown in Fig. 4, the casing 26 is formed on the upper surface of the casing body 41 which is formed by injection molding using a transparent polypropylene resin material, and a large amount of radiant heat absorbing layer 42 containing carbon black is formed, and a surface cosmetic layer 43 is formed thereon. The surface makeup layer 43 is a light-blocking layer' that shields all visible light emitted by the lamp heater 29, and takes into consideration surface hardness, chemical properties, gloss, and the like. Housing 201019877 The main body 41 is formed of a transparent polypropylene resin material with an average thickness of 2.5 mm, whereby the heat radiation transmittance is set to 70% or more, and the rigidity thereof is used as a structural moment of the barrel base. Further, the thickness of the radiant heat absorbing layer 42 formed is 0.1 mm, and the thickness of the surface cosmetic layer 43 is 〇.2 mm. The two layers can completely absorb the heat of penetration through the body 41, and the heat capacity is very small, so that in an instant When the temperature is raised, the visible light can be completely shielded. The recess provided in the inner surface of the casing 26 is embedded with a thermal resistor 44 which is in contact with the radiant heat absorbing layer 42 and has substantially the same temperature as the radiant heat absorbing layer 42. Therefore, the temperature of the radiant heat absorbing layer 42 can be directly detected. Further, the rear portion of the toilet seat 22 is provided with a swivel shaft 45 extending in the left-right direction, and the toilet seat 22 can be rocked up and down between the standing state and the horizontal use state by using the swivel action 45 as a base point. The rotary shaft 45 is formed with an electrode 46, and together with a bearing portion (not shown) of the body 21, constitutes a toilet seat position detecting mechanism 47, and can detect that the toilet seat is in a standing position or a substantially horizontal use position for seating use. The main body 21 is provided with a control unit 50 having a room temperature detecting sensor 48 and a timing unit 49. The room temperature detecting sensor 48 is used as a sensor for detecting room temperature, and the timing unit 49 is for calculating the toilet seat 22 The elapsed time from the point in time when the lamp heater 29 is energized to start heating up. The signals from the human body detecting unit 25, the seating detecting mechanism 38, the thermal resistor 44, the toilet seat position detecting mechanism 47, and the room temperature detecting sensor 48 are respectively transmitted to the control unit 50' and the lights are controlled according to the signals. The heater 29 is energized to bring the temperature above the toilet seat 22 of the warm surface to a predetermined temperature. Further, as shown in Fig. 2, the indoor heating unit 52 is provided in the toilet room, and the indoor heating unit 52 has an indoor heating heater 53 and an indoor heating fan 54, which can be heated in the toilet room. According to the above configuration, when the user enters the toilet, the human body detecting unit 25 can detect that the user has entered the toilet and transmit the signal to the control unit 50 through the infrared sensing unit 24. At this time, when the toilet seat position detecting means 47 confirms that the toilet seat 22 is at the substantially horizontal use position, the control unit 50 starts energizing the lamp heater 29. After the energization is started, the filament 33 is irradiated with light toward the casing body 41 via the glass tube 32 and the radiation reflecting plate 28, so that the light is instantaneously radiated as radiant energy. Further, although the radiant energy is partially absorbed or reflected inside the casing body 41, most of the radiant energy penetrates to contribute to the temperature rise of the radiant heat absorbing layer 42 and the surface cosmetic layer 43. Since the heating surface of the seat portion of the toilet seat 22 can be heated almost instantaneously as described above, it is not necessary to constantly energize the heater, which is very energy-saving. In the present embodiment, the heating element for heating the seat portion of the toilet seat 22 is a lamp heater 29. However, the heating element is not limited to the lamp heater 29, and for example, a linear heater using a twist line is used. The inner surface of the seat portion of the toilet seat 22 may be adhered to. The spotting line has good heat resistance, and the toilet seat 22 can be heated in a very short period of time to ensure electrical insulation and safety. <2> Power-on procedure of the toilet seat device The drive control of the lamp heater 29 is performed by dividing the electric power for driving the lamp heater 29 into three types. For example, when the toilet seat 22 is heated by the first temperature gradient, the control unit 50 drives the lamp heater 29 (1200 W drive) with an electric power of about 1200 W. If the resistance value of the lamp heater 29 is 8.33 Ω, when an alternating current of 100 V is applied to the lamp heater 29, a power of (100 V x 100 V) + 8.33 Q = 1,200 W is generated. In other words, by flowing current to the lamp heater 29 due to the entire period of the AC power source, 1200 W of electric power is generated. Further, when the toilet seat 22 is heated up by the second temperature gradient which is slightly slower than the first temperature gradient, the control unit 50 drives the lamp heater 29 (600 W drive) with an electric power of about 500 W. Next, when the temperature of the toilet seat 22 is kept constant, the control unit 5 drives the lamp heater 29 (low-power drive) with an electric power of about 50 W. However, the so-called low-power drive means that the lamp heater 29 is driven with power (e.g., 0 W to 50 W) that is driven by much less than 1200 W and driven by 600 W. The switching between the 1200 W drive, the 600 W drive, and the low-power drive is performed by the control unit 50 controlling the energization of the lamp heater 29 by the energization rate switching circuit of the control unit 50. The control unit 50 supplies an alternating current from a power supply circuit (not shown). Therefore, the control unit 50 flows the electric current to the lamp heater 29 in accordance with the AC current supplied from the energization control circuit. Fig. 5 shows a driving example of the lamp heater 29 and a surface temperature change of the toilet seat 22. Fig. 5 is a graph showing the relationship between the surface temperature of the toilet seat 22 and the time, and the relationship between the energization rate and the time when the lamp heater 29 is driven. The horizontal axes of the two charts are common timelines. In the present embodiment, it is assumed that the user turns on the warming function in advance and sets the toilet set temperature to a high level (38 ° C). When the room temperature such as winter is lower than 18 °C of the standby temperature, the control unit 50 adjusts the temperature to bring the temperature of the toilet seat 22 to 18 °C. In this manner, the control unit 50 performs low-power driving of the lamp 13 201019877 heater 29 when the human body detecting unit 25 detects the standby period di until the user enters, and the surface temperature of the toilet seat 22 reaches 18 C and is fixed. In the low-power driving of the standby period D1, the energization of the lamp heater 29 is changed in accordance with the temperature in the septic chamber, thereby reducing the power consumption, which will be described later. The control unit 50 performs 600 W drive between the inrush current reduction period D2 when the human body detecting unit 25 detects that the user has entered at time t1. However, the 600W drive is performed to reduce the inrush current sufficiently. The lamp heater 29 generates a large inrush current when the filament 33 before cooling is cooled. Even if the overcurrent generated here is temporary, it imposes a burden on the heater or the circuit, which adversely affects the life. Although electronic components that are resistant to overcurrent can be used for circuit setting, the cost is increased. In the present embodiment, first, a half amount of electric power is input to suppress an inrush current to control the influence. At this time, the surface temperature of the toilet seat 22 rises with a slightly gentle second temperature gradient. Here, although the human body detecting unit 25 detects the time point at which the user enters as the time t1, it is not limited thereto. For example, a mechanism for detecting the opening and closing of the door when the toilet is opened can be set in advance, and the time point at which the door is opened can be detected as the time t1. When the detection door is opened in this manner, as in the case of using the human body detecting portion 25, the intention of the user to appear to be seated on the toilet seat 22 can be detected. Therefore, by setting the time point to the time u, the toilet seat 22 is warmed up to the appropriate temperature. temperature. Further, a mechanism for detecting the intention of the user to sit in advance may be employed, or a mechanism for detecting the opening operation of the toilet lid 23 (an operation to open upward) or a mechanism for detecting the movement of the toilet seat 22 downward may be employed. Thereafter, the control unit 50 starts the 1200 W driving of the lamp heater 29 at the time 201019877 t2 after the inrush current reduction period D2 elapses, and continues the 1200 W driving of the lamp heater 29 in the first heating period D3. At this time, the surface temperature of the toilet seat 22 rises by the first temperature gradient. Here, the surface temperature of the toilet seat 22 rises sharply. The 1200W driving of the lamp heater 29 is performed until the surface temperature of the toilet seat 22 reaches a predetermined temperature (hereinafter also referred to as "the initial target temperature for use", for example, 30 〇. Of course, the predetermined temperature (using the initial target temperature) may also be The temperature is set to the temperature of the heating temperature, but the temperature is lower than the temperature at which the heating temperature is not sufficiently reached, as long as it is the lowest limit temperature (cold temperature limit temperature) that does not feel cold and uncomfortable when the user is seated. According to experiments conducted by the inventors, the limit temperature is about 29° C. In other words, if the initial target temperature is higher than the standby temperature, it is estimated that the user is seated on the toilet seat 22 . The temperature in the temperature range (for example, about 29 to 38 ° C) may be used, and the lower limit value may be the above-mentioned cold sensing limit temperature (about 29. 〇. Thus, in the first heating period D3, the surface of the toilet seat 22 The temperature can be quickly raised to a predetermined temperature by the 1200 W drive, whereby the user can sit on the toilet seat 22 without feeling that the toilet seat 22 is cold. Here, the standby temperature (for example, l8 ° C) is based on the The temperature rise of the toilet seat 22 at the end of the temperature rise period 1) 3 (the initial target temperature is used) and the temperature rise capability of the lamp heater 29. In other words, during the period between the inrush current reduction period D2 and the first temperature increase period D3, The temperature of the lamp heater can be considered as the minimum temperature at which the target temperature can be reached, and the standby temperature can be set. '(4) The surface temperature of the seat 22, and the D1 is set to be lower as much as possible during the period of the 2010 201019877 machine, thereby reducing the power consumption for maintaining the standby temperature. In the present embodiment, the lamp heater 29 is The heating capacity can be increased by the temperature of the surface of the toilet seat 22 at a speed of 〇5 to 5 gram sec/sec. Alternatively, during the detection of the intention of the user to the actual seating on the toilet seat 22. It is preferable to increase the temperature by about 3 to 25 ° C. Furthermore, it has been found by experiments by the inventors that, for example, in the case of a personal residence in Japan, the door from the toilet room is opened to the undressing seat. 22 is about 6 seconds on average. Therefore, it is better to have a specification that the standby temperature can reach the initial target temperature within about 6 seconds. At this time, the temperature rise temperature is at least 17 gram gram/second or more, and 2 gram/ear/ It is particularly preferable that the heater is not limited to the lamp heater 29, and may be attached to the sheet heater, the tube heater or the surface heater which does not use radiant heat. The inner surface of the seating surface or the other heating seating portion is configured, for example, by embedding a heater in a toilet seat member. Further, as described above, when the surface temperature of the toilet seat 22 is suddenly increased, the temperature change may cause an overshoot. (〇versh〇〇t) However, in the present embodiment, the 1200W drive of the lamp heater 29 is switched to 600W after the surface temperature of the toilet seat 22 reaches a predetermined temperature. Therefore, even if the surface temperature of the toilet seat 22 changes, the surface temperature does not exceed the set temperature of the toilet seat. As a result, the user can be prevented from feeling hot when sitting. Then, the control unit 50 starts the 600W driving of the lamp heater 29 at the time t3 after the first temperature rising period D3 elapses, and continues the 600W driving of the lamp heater 29 between the second temperature rising periods D4. At this time, the surface temperature of the toilet seat 22 is raised by the above-mentioned second temperature gradient of 16 201019877. The 600W drive of the lamp heater 29 is carried out until the surface temperature of the toilet seat 22 reaches the set temperature of the toilet seat (38. 〇). The second temperature gradient is slower than the second temperature gradient. Thereby, a large overshoot can be prevented from occurring in the surface temperature change of the toilet seat 22. The control unit 50 starts the low-power driving of the lamp heater 29 at the time t4 after the second temperature rising period D4 elapses, and continues the low-power driving of the lamp heater 29 between the second sustain period D5. Thereby, the surface temperature of the toilet seat 22 is maintained constant at the set temperature of the toilet seat. When the seat detecting mechanism 40 detects that the user is seated on the toilet seat 22 at time t5, the control unit 50 lowers the energization rate of the low-power drive, and continues the low-electric drive of the lamp heater 29 so that the toilet seat 22 The surface temperature maintains the toilet seat set temperature between the first seating periods D6. In the present embodiment, the second seating period D6 is set to be about 1 minute. Further, the control unit 50 lowers the energization rate of the low-power drive at the time t6 after the first seating period D6 elapses, and continues the low-power driving of the lamp heater 29 so that the surface temperature of the toilet seat 22 is second. During the seating period D7, the temperature is lowered slightly below the toilet seat setting temperature (for example, 36. 〇. In the present embodiment, the second seating period D7 is set to about 2 minutes. After the second seating period D7 is passed by the control unit 50 At time t7, the conduction rate of the low-power drive is further lowered, and the low-power drive of the lamp heater 29 is continued, so that the surface temperature of the toilet seat 22 is maintained at a temperature slightly lower than the set temperature of the toilet seat during the second maintenance period D8. In the following description, the surface temperature of the toilet seat 22 (i.e., the temperature slightly lower than the fixed temperature of the toilet seat 17 201019877) during the second maintenance period D8 is referred to as the maintenance temperature. Thus, in the present embodiment, After sitting on the toilet seat 22, the control unit 50 gradually lowers the surface temperature of the toilet seat 22. Thereby, the user can be prevented from freezing and freezing at a low temperature. At the time 18, the seat detecting mechanism 4 〇 detects that the user has been used by the toilet. Block 2 2 when leaving' The control unit 50 stops the driving of the lamp heater 29 during the stop period 〇 9. Thereby, the surface temperature of the toilet seat 22 is lowered. The control unit 50 reaches the surface temperature of the toilet seat 22 at 18 (at time t9, again). The low-power drive of the lamp heater 29 is started, and the low-power drive of the lamp heater 29 during the standby period D1 is maintained so that the surface temperature of the toilet seat 22 is maintained at 18 ° C. The low-power drive of D10 is also the same as that in the standby period D1, and the power supply to the lamp heater 29- is changed according to the temperature in the toilet room, thereby reducing the power consumption. This portion will be described later. When the temperature gradient is gradually slowed down, The overshoot caused by the surface temperature of the toilet seat 22 can be sufficiently reduced. In this embodiment, after the user sits on the toilet seat 22, the electric power for driving the lamp heater 29 is adjusted to lower the surface temperature of the toilet seat 22. The light source heater 29 can also be stopped when the user sits on the toilet seat 22. At this time, the user can be prevented from being frostbited by the low temperature. As described above, in the present embodiment, the description is based on Time T8 detects that the user has left the toilet seat 22 to stop the driving of the lamp heater 29, but the driving of the lamp heater 29 can also be stopped for a certain period of time from the time t8 when the user has detected that the user has left the toilet seat 22. For example, after [minutes], at this time, when the user leaves the toilet seat 22 and then rests on the toilet 18 when the toilet is seated, the surface temperature of the toilet seat 22 does not decrease. Comfortably seated on the toilet seat 22. The energization state of the toilet seat 22 and the energization control signal of the energization rate switching circuit are described together when driving at 1200 W, driving at 600 W, and driving at low power. The ratio of the time during which the alternating current flows to the toilet seat 2 2 (correctly, the lamp heater 29) with respect to one cycle of the alternating current. Therefore, the electric current rate to the lamp heater 29 is high, indicating that the electric power for energizing the lamp heater 29 is large, and the lower electric current rate indicates that the electric power for energizing the lamp heater 29 is small. Fig. 6(a) is a waveform diagram showing the current flowing to the toilet seat 22 (correctly, the lamp heater 29) when the 1200W is driven, and Fig. 6(b) is the control unit given to the control unit by the energization rate switching circuit when the 1200W is driven. Waveform of the 50 power control signal. As shown in Figure 6(b), the power-on control signal for the 1200W drive is often a logic "1". When the energization control signal is logic "丨", the control unit 50 causes the alternating current supplied from the power supply circuit to flow to the toilet seat 22 (the thick line portion of Fig. 6(a)). Thereby, the alternating current flows to the toilet seat 22 during the entire period. As a result, the toilet seat 22 is driven by an electric power of about 1200 watts. Fig. 7(a) is a waveform of a current flowing through the toilet seat 22 during driving of 600 W. Fig. 7(b) is a waveform diagram of an energization control signal given to the control unit 50 by the energization rate switching circuit at the time of driving 600 W. As shown in Fig. 7(b), the energization control signal at the time of driving at 600 W is constituted by a pulse wave of the same period as the alternating current supplied to the control unit 50. Pulse wave 19 201019877 The ratio of the work width (ratio of the pulse width of the logic Γι to the pulse period) is set to 50%. control. When the energization control signal is logic "i", the alternating current supplied from the power supply circuit flows to the toilet seat 22 (the thick line of the seventh (4) drawing, whereby the alternating current flows to the toilet seat 22 during a half cycle. As a result, the toilet seat 22 is driven by an electric power of about 600 W. Fig. 8(a) is a waveform diagram of current flowing to the toilet seat 22 during low-power driving, and Fig. 8(b) is switched by electric current rate when driving with low electric power The circuit gives a waveform diagram of the energization control signal of the control unit 50. As shown in Fig. 8(b), the energization control signal at the time of low-power driving is constituted by a pulse wave of the same period as the alternating current supplied to the control unit 50. The operation ratio of the wave is set to be less than 50% (for example, about several % p ' of the control unit 50 when the energization control signal is logic "1", the alternating current supplied from the power source and the path flows to the toilet seat 22. As a result, the scorpio 22 is driven by, for example, about 50 W. In addition to the above, when the temperature of the toilet seat 22 is lowered, or when the heating function of the toilet seat mounting device 110 is turned off, the energization rate switching circuit is not given to the control unit 50. Signal (will be energized) The control unit 50 does not drive the toilet seat 22. Here, in general, when the current supplied to the electronic device has a harmonic component, noise is generated. In the present embodiment, When the 1200W drive or the 600W drive of the toilet seat 22 is performed as described above, since the current supplied to the toilet seat 22 changes sinusoidally, even if the current is large, the generation of noise can be sufficiently reduced. 20 201019877 Further, the toilet seat 22 is In the low-power drive, although the current supplied to the toilet seat 22 has a high-modulation component, the current is relatively small compared to the drive and the 600W drive, so that the noise can be sufficiently reduced.
如上所述，本實施形態中，係以1200W、600W及約50W 之電力來驅動馬桶座22 ’但以其它大小之電流來驅動馬桶 座22亦可。 舉例言之’在半週期之期間將交流電流流動於馬桶座 22時’以2週期或3週期等預定週期之間隔來設定流動交流 電流之時序。藉此，利用與1200W、600W及約50W不同大 小之電力’可充分防止雜訊之產生並驅動馬桶座22。 而’本實施形態中，控制部50在通電控制訊號為邏輯 「1」時’對馬桶座22供給電流，而當通電控制訊號為邏輯 「〇」時，則停止對馬桶座22供給電流’但亦可在通電控制 訊號為邏輯「1」時’停止對馬桶座22供給電流，而當通電 控制訊號為邏輯「〇」時，則對馬桶座22供給電流。 而’燈式加熱器29之開啟或關閉係以時間控制，因此 若時間之測量偏差，馬桶座22之溫度會超過預定值或無法 達預定值。故，控制部50會以2個測量源來測量馬桶座22之 開啟時間，以使時間測量不產生偏差。其中一個測量源係 利用規定控制部50之程式實效速度的振盪元件來測量燈式 加熱器29之開啟時間，另一個測量源則以交流電流之週期 作為基準來測量燈式加熱器29之開啟時間。當這些測量值 的至少其中之一超過規定時間時，便進入下一個通電模式。 特別是，可正確測量對馬桶座通電1200W之時間，藉 21 201019877 此確實地防止過昇溫。藉此，可進而提高㈣之安全性。 在此，已記載設置複數測量源來提高測量精度之方法，但 測量燈式加熱器29全通電之時間，強制阻斷或限制對加熱 器之通電的方法，亦可獲得相同效果。 <3>顯示LED之動作 本體21之上面設有作為通報機構之顯示LED28〇(第i 圖）顯示LED280在對燈式加熱器29通電時開始閃爍，並於 馬桶座22之溫度上昇而達到前述冷感界限溫度(29〇c )時恆 亮。 參 顯示LED280在檢出溫度（熱阻器44測量溫度)較冷感界 限溫度低時，進行第1通知形態之閃爍，在檢測溫度較高 時，進行第2通知形態之恆亮，因此使用者觀看顯示LED28〇 便可判別是否會感到馬桶座22之就座面冷，而可就座於馬 桶座22。 又，利用以人體檢測部25檢測廁所有無人體之功能， 當使用者離開廁所而經過一定時間後(例如丨分鐘），停止燈 式加熱器29之通電，顯示LED280不會呈閃爍或點亮狀態而 熄滅。再者，即使未經過一定時間，當馬桶蓋關閉時也會 熄滅。 顯示LED280之通知由第1通知形態變為第2通知形態 之時期，係如前述在馬桶座22之就座面溫度已達界限溫度 29°C 時。 第9圖顯示馬桶座22之表面溫度與熱阻器44之測量溫 度值之關係。如第9圖所示，馬桶座22之就座面溫度與熱阻 22 201019877 益44之測量溫度值會因測量面不同而產生差異。瞬間昇溫 之馬桶座’熱阻||44之溫度喊較慢，歸正確地檢測馬 桶座22之就座面溫度。故，以熱阻器44之測量溫度值使第2 通知形態之顯示LED280點亮時’必須預先測量馬桶座22之 溫度上昇值與熱阻器44之測量溫度值之關聯，以預測溫度 回應之誤差。 舉例言之’相對於馬桶座22之就座面昇溫，熱阻器44 之昇溫降低10%時，在馬桶座22之就座面溫度由18。〇上昇 11度至29C的期間，熱阻器44之昇溫為9.9度。故，只要在 檢測出熱阻器44為27.9°C時，將顯示LED280由閃爍切換至 恆亮即可。 又’亦可預先測量通電開始前之熱阻器44之檢測溫度 與此時馬桶座22就座面到達冷感界限溫度所需之到達時間 之關聯’決定通電開始時之溫度到通知變更之時間。舉例 言之，預先知悉通電前之溫度t0為18°C，此時就座面昇溫 至29°C所需之時間tl為5.5秒，若t0為20°C則tl為4.5秒之關 聯’而只在初期溫度（即t0)變更通知。上述構成對熱阻器44 之檢測延遲較大時很有效。 惟，熱阻器44之測量溫度值與馬桶座22之就座面溫度 的關聯、或通電開始時之溫度與到達時間的關聯，很難預 先加上電壓、室溫等設置環境或燈式加熱器29之電阻值等 的差異等造成的個體差異。此時，由於會無法於適當之時 期通知使用者，因此必須根據使用環境或個體差進行修正。 <4>室溫檢測感測器之修正 23 201019877 說明根據廁所室内溫度來修正顯示LED280之通知時 期’以消除熱阻器44之測量溫度值與馬桶座22之就座面溫 度之誤差的情況。在此，根據設置於本體21之室溫檢測感 測器48所檢測出之室溫，使用一以放熱量（放熱量係依預先 記憶於控制部5 0之記憶部的各個室溫所設定）為基準之修 正值來修正顯示LED280之通知時期。第1〇圖顯示室溫變動 時’熱阻器44之測量溫度值與馬桶座22之就座部表面溫度 及通知時期之關係。 舉例言之，當室溫（第10圖中以RT表示）為15°C而將馬 ® 桶座22保溫於18°C時，若誤差為ι〇%(相對於馬桶座22之就 座部表面溫度之昇溫速度，熱阻器44檢測之昇溫速度為「一 ⑺％」），相對於馬桶座22之就座部表面溫度為冷感界限溫 ： 度之29.0C(由待機溫度18°C上昇ll°c所到達之溫度），在熱 ' 阻器44檢測之溫度為27.9〇C (將由i丨它減去丨〇%之9 9χ：加算 於待機溫度18t：之值）時將通知由閃爍變更為恆亮。這在室 溫5°C時馬桶座22之放熱較大而誤差較小。例如誤差為8% 時，應修正之誤差為〇.88deg，只要在28 12t變更通知即可。 © 以上已就本實施形態中通知時期為冷感界限溫度之情 況進行說明，但亦可為設定溫冑或依據該言史定溫度之溫度。 一般溫度控制可活用例如正確掌握到達設定溫度之到 達溫度的機構。換言之，亦可使用通電變更時期而非通知 時期之變更。通電控制係根據馬桶座表面溫度由㈣·變 更為600W或約50W之相位控制，但亦可用於該變更時期之 修正。由於利用修正可正確掌握馬桶座表面溫度已到_ 24 201019877 °c，因此可增加舒適性。 如前所述，馬桶座表面溫度之昇溫速度快，作為檢測 機構之熱阻器44會產生反應延遲，因此即使馬桶座表面溫 度到達設定溫度，檢測機構也會檢測出較設定溫度低之溫 度。該誤差與通知時期同樣，也會因設置環境之電麼或室 溫及馬桶座加熱器之電阻值差異而不同。故，進行與通知 時期同樣之修正’可正確地掌握到達溫度，而提供更舒適 •之馬桶座。 特別是就設定溫度而言，當反應延遲較預想之延遲大 時，馬桶座表面溫度會到達較設定溫度高的溫度。故，此 時可㈣環境溫度(朗冑内溫度)來進行修正，藉此提高舒 適性與安全性。 -· 特別是當室温低時，利用馬桶座22之放熱變大而馬桶 座表面溫度與熱阻器44之測量溫度之誤差變小，在室溫較 低時，亦可降低熱阻器44相對於設定溫度之目標溫度或人 • 肖未進人廁所之待機時的保溫溫度(本實施例中為18。〇。此 時可期待降低消耗電力。 _另一方面，由第10圖可知，當室溫高時，即使是從相 同的待機時保溫溫度，由於到設定溫度為止之昇溫速度較 快，因此馬桶座22會較快變暖。利用這點，可降低人尚未 進入廁所室之待機時保溫溫度(本實施例中為机）。此時亦 可期待降低消耗電力。 室溫檢測感測器之待機溫度控制 接著，說明根據廁所室内溫度，在待機期間（第5圖之 25 201019877 期間D1、D10等）中燈式加熱器29之低電力驅動時，改變對 燈式加熱器29之通電以降低消耗電力之控制部5〇所進行之 控制。 如以上所說明，根據廁所室内溫度之高低，馬桶座22 之放熱量會不同。舉例言之，當廁所室内溫度相對較高時， 來自馬桶座22就座面之放熱量會相對較少。故，假設使董十 燈式加熱器29通電之電力與廁所室内溫度較低時相同，會 因放熱量會較少而達到較高之溫度，而可能會超過設定之 待機溫度(例如18°C)。這會造成多餘電力之消耗而不理想。 故，本實施形態之馬桶座裝置係於利用室溫檢測感測 器48檢測廁所室内溫度，當廁所室内溫度相對較高時，進 行控制來降低對燈式加熱器29之通電率（即通電之電力），而 在廁所室内溫度相對較低時，則進行控制來使通電率增加。 第14圖係顯示如此根據廁所室内溫度來改變通電率之 態樣例的圖表，在此通電率係以用第6〜8圖說明之工作比來 表示。如第14圖所示，設定成橫轴所示之溫度相對越高， 工作比越小，即通電率越小。故，無論廁所室内溫度之變 化，皆可將馬桶座22就座面溫度維持於預定待機溫度。 故，例如廁所室内溫度較高時，在已超過預定待機溫 度之狀態下會待機，而可控制因昇溫至必要溫度以上之溫 度所產生之多餘消耗電力。又，相反地，當廁所室内溫度 較低時’可避免保溫在預定待機溫度以下，而當使用者入 室時無法以希望之時間昇溫至使用初期目標溫度之情況。 而，檢測用以對控制部50傳送之廁所室内溫度的時間 201019877 點，可设疋為當人體檢測部25已檢測到人體時。又，亦可 於人體檢測部25或操作遙控器（未圖示）預先設置計時機 構，每當經過一定時間即檢測廁所室内溫度，並根據如此 所獲得之最新室溫資訊來控制之後的待機溫度。 <6>室溫檢測感測器之共用 惟，本實施形態之控制部50於例如第5圖所示之第1昇 溫期間D3中，執行第1步驟，接著執行第2步驟，第丨步驟係 根據通電開始時之熱阻器44及室溫檢測感測器48之訊號， 由兩者之溫度差或分別之溫度進行運算，選擇預先設定及 記憶之通電限制時間之最佳值，並於計時部49所計數之經 過時間到達通電限制時間時，降低通電量或使通電量為〇, 而第2步驟則根據熱阻器44之訊號來控制通電量，使馬桶座 22之就座部到達適溫。 本實施形態之廁所室設置有進行廁所室内加溫之室内 暖氣部52，該室内暖氣部52藉著控制部50如上述般檢測來 自第1步驟所利用之室溫檢測感測器48之訊號，進行室内暖 氣加熱器53與室内暖氣風扇54之輸出控制。如此一來，藉 著以同一溫度感測器進行馬桶座控制溫度與室内暖氣溫度 控制，便不需設置馬桶座控制專用之溫度感測器，可實現 構造單純、低價、精度高且舒適之馬桶座溫度控制。同樣 地，用於待機期間中控制燈式加熱器29之通電率的廁所室 内溫度檢測機構也可與用於室内暖氣溫度控制之溫度感測 器共用，而可達到上述效果。 (實施形態2) 27 201019877 第11圖係本發明實施形態2之具溫水洗淨功能的馬桶 座裝置構成圖。與實施形態1不同之處在於，設置有對洗淨 後之局部吹出暖風之乾燥功能部55。 控制部50利用來自室溫檢測感測器56之訊號進行乾燥 加熱器57與乾燥風扇58之輸出控制。且，利用同一溫度感

用紅外線發光部將來自室溫檢測感測器59之訊號傳送至本 體21之控制部50。人體檢測部25根據來自室溫檢測感測器 59之訊號，進行人體檢測感測器之靈敏度及輸出之修正。 且，利用同一室溫檢測感測器59進行馬桶座之溫度控 制（包含待機期間中之通電率控制）與人體檢測部25之人體 檢測感測器之修正，便不需設置馬桶座控制專用之溫度感 測器，可與實施形態1、2同樣地，實現構造單純、低價、 精度高且舒適之馬桶座溫度控制。 (實施形態4) 第13圖係本發明實施形態4之具溫水洗淨功能的馬桶 座裝置構成圖。與實施形態1〜3不同之處在於，在一將供水 28 201019877 源所供給之洗淨水加熱並將洗淨水喷出至人體之溫水洗淨 功能部60，具有一檢測供水源之水溫的入水溫度檢測機構 61，控制部50根據馬桶座22之熱阻器44與入水溫度檢測機 構61之訊號，進行馬桶座之溫度控制。即，由入水溫度推 測室溫。 且，藉由以同一溫度感測器（入水溫度檢測機構61)來進 行馬桶座之溫度控制（包含待機期間中之通電率控制）與洗 淨水之溫度控制，便不需設置馬桶座控制專用之溫度感測 器，可與實施形態1〜3同樣地，實現構造單純、低價、精度 高且舒適之馬桶座溫度控制。 <7>其它構成 上述實施形態2〜4已就共用室溫檢測感測器之情形進 行說明，但由於搭載之功能會因馬桶座裝置而異，因此只 要視情況共有室溫感測器即可。若是搭載了 2個以上功能之 馬桶座裝置，亦可共有2個以上室溫檢測感測器。 又，當然亦可設置用於馬桶座22溫度控制而專門檢測 廁所室内溫度之室溫感測器。此時，可適當選擇設置處， 藉此進行更正確之廁所室内溫度檢測。舉例言之，上述設 置處可為與人體檢測部25或本體21分開而另外準備之操作 遙控器。又，只要可進行較正確之檢測，亦可於上述室内 暖氣部52設置專門檢測廁所室内溫度之室溫檢測感測器。 或於照明器具設置上述室溫檢測感測器。 又，亦可設置複數專門檢測廁所室内溫度之室溫檢測 感測器。此時，複數室溫檢測感測器中，至少一個可與具 29 201019877 有其它目的之溫度感測器共用。 又，本實施形態1〜4中，馬桶座係將合成樹脂製的上下 2個構件分別在其内周緣與外周緣融化接合而形成殼體者， 但為了提高加熱器之昇溫能力並確保昇溫溫度，宜盡量降 低欲加溫之馬桶座構件的熱容量。故，亦可設置鋁合金等 金屬構成之就座部。利用前述構成，可構成昇溫特性與均 勻性更加的加溫馬桶座。 產業上利用之可能性 本發明適用於一種可在無損於廁所使用者之舒適性的 情況下’進一步降低調整馬桶座溫度時的消耗電力來實現 節能化之馬桶座裝置。 【囷式簡單說明】 第1圖係本發明實施形態1之馬桶座裝置的外觀立體 圖。

power of 1200 W, 600 W and about 50 W, but the toilet seat 22 may be driven by a current of another magnitude. For example, when an alternating current flows to the toilet seat 22 during a half cycle, the timing of the flow alternating current is set at intervals of a predetermined period of two cycles or three cycles. Thereby, the power of "different from 1200 W, 600 W and about 50 W" can be used to sufficiently prevent the generation of noise and drive the toilet seat 22. In the present embodiment, the control unit 50 supplies current to the toilet seat 22 when the energization control signal is logic "1", and stops supplying current to the toilet seat 22 when the energization control signal is logic "〇". It is also possible to stop supplying current to the toilet seat 22 when the power-on control signal is logic "1", and to supply current to the toilet seat 22 when the power-on control signal is logic "〇". On the other hand, the opening or closing of the lamp heater 29 is controlled by time, so that if the measurement of time is deviated, the temperature of the toilet seat 22 may exceed a predetermined value or may not reach a predetermined value. Therefore, the control unit 50 measures the opening time of the toilet seat 22 with two measuring sources so that the time measurement does not cause a deviation. One of the measurement sources measures the turn-on time of the lamp heater 29 by using an oscillating element that specifies the effective speed of the program of the control unit 50, and the other measurement source measures the turn-on time of the lamp heater 29 with the period of the alternating current as a reference. . When at least one of these measured values exceeds the specified time, the next energization mode is entered. In particular, it is possible to correctly measure the time when the toilet seat is energized for 1200 W, and by 21 201019877, this is surely prevented from overheating. Thereby, the safety of (4) can be further improved. Here, a method of setting a plurality of measurement sources to improve the measurement accuracy has been described. However, the same effect can be obtained by measuring the time during which the lamp heater 29 is fully energized and forcibly blocking or limiting the energization of the heater. <3> The display LED 28 as the notification means is provided on the upper surface of the operation body 21 of the display LED. The display LED 280 starts to blink when the lamp heater 29 is energized, and rises at the temperature of the toilet seat 22 to reach The above-mentioned cold feeling limit temperature (29〇c) is always bright. When the detection temperature (the temperature measured by the thermistor 44) is lower than the cold sensing limit temperature, the LED 280 performs the flickering of the first notification form, and when the detection temperature is high, the second notification mode is constantly lit, so the user By viewing the display LED 28, it can be determined whether or not the seating surface of the toilet seat 22 is cold, and can be seated on the toilet seat 22. Further, the human body detecting unit 25 detects the presence or absence of the function of the human body in the toilet, and when the user leaves the toilet and waits for a certain period of time (for example, 丨 minute), the energization of the lamp heater 29 is stopped, and the display LED 280 does not blink or light. And extinguished. Furthermore, even if the toilet cover is closed, it will be extinguished even after a certain period of time has elapsed. The notification of the display LED 280 is changed from the first notification mode to the second notification mode, as described above when the seating surface temperature of the toilet seat 22 has reached the limit temperature of 29 °C. Fig. 9 shows the relationship between the surface temperature of the toilet seat 22 and the measured temperature value of the thermistor 44. As shown in Fig. 9, the seating surface temperature and thermal resistance of the toilet seat 22 will vary depending on the measuring surface. The instantaneous temperature rise of the toilet seat 'thermal resistance||44 temperature is slower, and the seat surface temperature of the barrel base 22 is correctly detected. Therefore, when the display LED 280 of the second notification mode is illuminated by the measured temperature value of the thermistor 44, the relationship between the temperature rise value of the toilet seat 22 and the measured temperature value of the thermistor 44 must be measured in advance to predict the temperature response. error. For example, when the seating surface of the toilet seat 22 is warmed up and the temperature rise of the thermistor 44 is reduced by 10%, the seating surface temperature of the toilet seat 22 is 18. During the period from 11 degrees to 29C, the temperature rise of the thermistor 44 is 9.9 degrees. Therefore, as long as the heat resistor 44 is detected to be 27.9 ° C, the display LED 280 is switched from blinking to constant light. In addition, the relationship between the detected temperature of the thermal resistor 44 before the start of energization and the arrival time required for the seating surface of the toilet seat 22 to reach the cold limit temperature can be measured in advance, and the temperature at the start of the energization is determined to the time of the notification change. . For example, it is known in advance that the temperature t0 before energization is 18 ° C, and the time t1 required for the seat surface to rise to 29 ° C is 5.5 seconds, and if t0 is 20 ° C, t1 is 4.5 seconds. The notification is only changed at the initial temperature (ie t0). The above configuration is effective when the detection delay of the thermistor 44 is large. However, the correlation between the measured temperature value of the thermistor 44 and the seating surface temperature of the toilet seat 22, or the temperature at the start of energization and the arrival time, it is difficult to add a setting environment such as a voltage or a room temperature or a lamp heating in advance. The individual difference caused by the difference in resistance value or the like of the device 29. At this time, since it is impossible to notify the user at an appropriate time, it is necessary to correct it according to the use environment or individual difference. <4> Correction of room temperature detecting sensor 23 201019877 Description Correcting the notification period of display LED 280 according to the temperature of the toilet room to eliminate the error of the measured temperature value of the thermistor 44 and the seating surface temperature of the toilet seat 22. . Here, according to the room temperature detected by the room temperature detecting sensor 48 provided in the main body 21, a heat release amount is used (the heat release amount is set in accordance with each room temperature of the memory unit previously stored in the control unit 50) The notification period for displaying the LED 280 is corrected for the correction value of the reference. Fig. 1 is a graph showing the relationship between the measured temperature value of the thermistor 44 and the surface temperature of the seat portion of the toilet seat 22 and the notification period when the room temperature fluctuates. For example, when the room temperature (indicated by RT in Fig. 10) is 15 ° C and the horse® barrel 22 is kept at 18 ° C, the error is ι 〇 % (relative to the seating portion of the toilet seat 22) The temperature rise rate of the surface temperature, the temperature rise rate detected by the thermistor 44 is "one (7)%"), and the surface temperature of the seat portion of the toilet seat 22 is the cold temperature limit temperature: 29.0 C (by the standby temperature of 18 ° C) The temperature reached by ll°c rises, and the temperature detected by the thermal resistor 44 is 27.9 〇C (which will be subtracted from 丨〇% by 9 χ: added to the standby temperature of 18t:) The flashing changes to constant light. When the room temperature is 5 ° C, the heat release of the toilet seat 22 is large and the error is small. For example, if the error is 8%, the error to be corrected is 〇.88deg, as long as the notification is changed at 28 12t. © The above description has been made on the case where the notification period is the cold sensing limit temperature, but it may be set to the temperature or the temperature according to the history. The general temperature control can utilize, for example, a mechanism that correctly grasps the temperature at which the set temperature is reached. In other words, it is also possible to use a change in the power-on change period instead of the notification period. The energization control is controlled by the phase of the toilet seat surface from (4) to 600 W or about 50 W, but can also be used for correction of the change period. Since the correction can be used to correctly grasp the surface temperature of the toilet seat has reached _ 24 201019877 °c, so the comfort can be increased. As described above, the temperature rise of the toilet seat surface temperature is fast, and the thermal resistor 44 as the detecting mechanism generates a reaction delay. Therefore, even if the toilet seat surface temperature reaches the set temperature, the detecting mechanism detects a temperature lower than the set temperature. This error is the same as the notification period, and will vary depending on the setting of the environment or the room temperature and the difference in the resistance of the toilet seat heater. Therefore, the same correction as in the notification period is carried out, and the toilet seat can be provided with a more comfortable arrival temperature. In particular, in terms of set temperature, when the reaction delay is greater than the expected delay, the toilet seat surface temperature will reach a temperature higher than the set temperature. Therefore, at this time, (4) the ambient temperature (the temperature inside the reading) can be corrected to improve the comfort and safety. - Especially when the room temperature is low, the heat dissipation by the toilet seat 22 becomes large, and the error between the surface temperature of the toilet seat and the measured temperature of the thermistor 44 becomes small, and when the room temperature is low, the relative resistance of the thermistor 44 can also be lowered. The target temperature at the set temperature or the holding temperature at the standby of the person who has not entered the toilet (18 in this embodiment. 此时. At this time, it is expected to reduce the power consumption. _ On the other hand, it can be seen from Fig. 10, when When the room temperature is high, even if the temperature is raised from the same standby temperature, the temperature rises to the set temperature is faster, so the toilet seat 22 is warmed faster. By using this, the standby time when the person has not entered the toilet room can be reduced. The holding temperature (in this embodiment, the machine). At this time, it is also expected to reduce the power consumption. The standby temperature control of the room temperature detecting sensor Next, according to the temperature of the toilet room, during the standby period (Fig. 5, 25, 2010, during the period of 2010, 7) When D4 or the like is driven by the low electric power of the lamp heater 29, the control of the power supply to the lamp heater 29 is performed to reduce the power consumption of the control unit 5〇. As explained above, according to the toilet room temperature The heat release of the toilet seat 22 may be different. For example, when the temperature in the toilet room is relatively high, the heat release from the seating surface of the toilet seat 22 will be relatively small. Therefore, it is assumed that the Dongshi lamp heater 29 is energized. The power is the same as when the room temperature in the toilet is low. It will reach a higher temperature due to less heat release, and may exceed the set standby temperature (for example, 18 ° C). This will cause unnecessary power consumption. Therefore, the toilet seat apparatus of the present embodiment detects the temperature in the toilet room by the room temperature detecting sensor 48, and when the temperature in the toilet room is relatively high, controls to reduce the energization rate of the lamp heater 29 (i.e., energization). When the temperature in the toilet room is relatively low, control is performed to increase the power supply rate. Fig. 14 is a diagram showing a state in which the power supply rate is changed according to the temperature in the toilet room, and the power supply rate is used here. The working ratios shown in Figures 6 to 8 are shown. As shown in Fig. 14, the temperature indicated by the horizontal axis is relatively higher, and the smaller the working ratio, that is, the smaller the conduction rate. The change in temperature can maintain the seating surface temperature of the toilet seat 22 at a predetermined standby temperature. Therefore, for example, when the temperature in the toilet room is high, the standby temperature is exceeded, and the temperature rises to the necessary temperature. The excess power consumption generated by the above temperature. Conversely, when the temperature in the toilet room is low, the insulation can be avoided below the predetermined standby temperature, and when the user enters the room, the temperature cannot be raised to the initial target temperature. In the case of detecting the temperature of the toilet room to be transmitted to the control unit 50, the time of 201019877 may be set to be when the human body detecting unit 25 has detected the human body. Also, the human body detecting unit 25 or the remote controller may be operated ( Not shown in the figure) The timing mechanism is set in advance, and the temperature in the toilet room is detected every time a certain period of time is elapsed, and the subsequent standby temperature is controlled based on the latest room temperature information thus obtained. <6> The room temperature detecting sensor is shared by the control unit 50 of the present embodiment. For example, in the first temperature rising period D3 shown in Fig. 5, the first step is executed, and then the second step and the second step are executed. According to the signal of the thermistor 44 and the room temperature detecting sensor 48 at the start of energization, the temperature difference or the temperature of the two are calculated, and the optimal value of the preset and stored energization limiting time is selected, and When the elapsed time counted by the timer unit 49 reaches the energization limit time, the amount of energization is reduced or the amount of energization is reduced, and in the second step, the amount of energization is controlled according to the signal of the thermistor 44, so that the seating portion of the toilet seat 22 is reached. Suitable temperature. In the toilet room of the present embodiment, an indoor heating unit 52 for heating the toilet room is provided. The indoor heating unit 52 detects the signal from the room temperature detecting sensor 48 used in the first step by the control unit 50 as described above. The output control of the indoor heating heater 53 and the indoor heating fan 54 is performed. In this way, by using the same temperature sensor for the toilet seat control temperature and the indoor heating temperature control, it is not necessary to provide a temperature sensor for the toilet seat control, which can realize simple structure, low price, high precision and comfort. Toilet seat temperature control. Similarly, the toilet room temperature detecting mechanism for controlling the energization rate of the lamp heater 29 during the standby period can be shared with the temperature sensor for the indoor heating temperature control, and the above effects can be attained. (Embodiment 2) 27 201019877 Fig. 11 is a view showing the configuration of a toilet seat device having a warm water washing function according to Embodiment 2 of the present invention. The difference from the first embodiment is that a drying function portion 55 that blows warm air to the portion after washing is provided. The control unit 50 controls the output of the drying heater 57 and the drying fan 58 by the signal from the room temperature detecting sensor 56. Moreover, the same temperature sensor is used to control the temperature of the toilet seat (including the conduction rate control during the standby period) and the temperature control of the drying, so that the temperature sensor for the toilet seat control is not required to be the same as in the first embodiment. Ground, realizes simple, low-cost, high-precision and comfortable toilet seat temperature control. (Third Embodiment) Fig. 12 is a view showing the configuration of a toilet seat apparatus having a warm water washing function according to a third embodiment of the present invention. The difference from the first and second embodiments is that the room temperature detecting sensor 59 is provided inside the human body detecting unit 25. The human body detecting unit 25 transmits the signal from the room temperature detecting sensor 59 to the control unit 50 of the body 21 by the infrared light emitting unit. The human body detecting unit 25 performs correction of the sensitivity and output of the human body detecting sensor based on the signal from the room temperature detecting sensor 59. Moreover, the same room temperature detecting sensor 59 performs temperature control of the toilet seat (including the power-on rate control in the standby period) and the correction of the human body detecting sensor of the human body detecting portion 25, so that it is not necessary to provide a toilet seat control. In the same manner as in the first and second embodiments, the temperature sensor can realize the toilet seat temperature control with simple structure, low cost, high precision, and comfort. (Fourth Embodiment) Fig. 13 is a view showing the configuration of a toilet seat apparatus having a warm water washing function according to a fourth embodiment of the present invention. The difference from the first to third embodiments is that the water supplied from the water supply 28 201019877 is heated and the washing water is sprayed to the warm water washing function unit 60 of the human body, and has a water for detecting the water supply source. The warm water inlet temperature detecting means 61, the control unit 50 performs temperature control of the toilet seat based on the signals of the thermal resistor 44 of the toilet seat 22 and the water inlet temperature detecting means 61. That is, the room temperature is estimated from the inlet water temperature. Moreover, by controlling the temperature of the toilet seat (including the conduction rate control during the standby period) and the temperature control of the washing water by the same temperature sensor (inlet water temperature detecting mechanism 61), it is not necessary to provide toilet seat control. In the same manner as in the first to third embodiments, the temperature sensor can realize the temperature control of the toilet seat which is simple in structure, low in cost, high in precision, and comfortable. <7> Other configurations of the above-described second to fourth embodiments have been described with respect to the case where the room temperature detecting sensor is shared. However, since the function to be mounted differs depending on the toilet seat device, the room temperature sensor is shared as appropriate. can. If you have a toilet seat unit with more than two functions, you can have more than two room temperature detection sensors. Further, it is of course possible to provide a room temperature sensor for detecting the temperature of the toilet room 22 for temperature control of the toilet seat 22. At this time, the setting place can be appropriately selected, thereby performing a more accurate detection of the indoor temperature of the toilet. For example, the above setting may be an operation remote controller separately prepared separately from the human body detecting portion 25 or the body 21. Further, as long as a relatively accurate detection is possible, a room temperature detecting sensor that specifically detects the temperature in the toilet room may be provided in the indoor heating unit 52. Or set the above room temperature detecting sensor to the lighting fixture. In addition, a plurality of room temperature detecting sensors for detecting the indoor temperature of the toilet may be provided. At this time, at least one of the plurality of room temperature detecting sensors may be shared with a temperature sensor having other purposes. Further, in the first to fourth embodiments, the toilet seat is formed by melting and joining the upper and lower members of the synthetic resin to the inner periphery and the outer periphery, respectively, but the temperature rise capability of the heater is raised to ensure the temperature rise temperature. It is advisable to reduce the heat capacity of the toilet seat member to be warmed as much as possible. Therefore, it is also possible to provide a seating portion made of a metal such as an aluminum alloy. According to the above configuration, it is possible to constitute a warm toilet seat having a higher temperature rising characteristic and uniformity. Industrial Applicability The present invention is applicable to a toilet seat device which can further reduce the power consumption when adjusting the temperature of the toilet seat without degrading the comfort of the toilet user.
