201244681 六、發明說明： 【發明所屬之技術領域】 本發明的態樣，是有關於可以將被設在馬桶的馬桶座 加溫的加熱式馬桶座裝置。 . 【先前技術】 一般，在大多的加熱式馬桶座裝置中，例如作爲電發 熱體的加熱器等是被設在馬桶座的內部。電流流動於加熱 器的話，藉由在加熱器所發生的焦耳熱的熱傳導使馬桶座 的表面的溫度上昇。例如馬桶座是由樹脂形成的情況，因 爲樹脂的熱電阻較大，所以爲了使馬桶座的表面的溫度上 昇至目標溫度需要花費數十秒至數分的時間。因此，爲了 讓使用者就坐在馬桶座時不會感到寒冷，即使使用者未就 坐在馬桶座時也有需要對於加熱器通電將馬桶座的表面預 熱。因此，對於抑制待機時的消耗電力，達成節能化的點 還具有改善的餘地。 對於此，有一種馬桶座加熱裝置具備：加熱器、及電 磁感應加熱線圈（專利文獻1)。在專利文獻1的馬桶座加 熱裝置中，若檢出進入廁所的話，使電磁感應加熱線圏作 動，將馬桶座瞬間加熱。進一步，就坐在'馬桶座之後是藉 由加熱器持續加熱。但是，瞬間加熱或急速加熱用的加熱 手段、及保溫加熱用的加熱手段，若設成不同系統的話’ 會有導致構造成爲複雜的問題和成本上昇的問題。 [先行技術文獻] -5- 201244681 [專利文獻] [專利文獻1]日本特開2008- 1 8 1 1 4號公報 【發明內容】 [本發明所欲解決的課題] 本發明，是基於這種課題的認識，其目的是提供一種 加熱式馬桶座裝置，可以由更簡易的構造實現急速加熱及 保溫加熱。 [用以解決課題的手段] 本發明可提供一種加熱式馬桶座裝置，具備：設有感 應加熱線圈及共振電容器的共振電路；及藉由前述感應加 熱線圈所發生的磁場被感應加熱的導電體；及設有前述導 電體的馬桶座；及具有第1開閉元件並供控制供給至前述 共振電路的電力用的變頻器；及將從商用電源被供給的電 流整流的整流部；及具有第2開閉元件並將前述整流部的 整流輸出降壓地供給至前述變頻器的降壓部；及控制部， 實行：控制前述變頻器使前述馬桶座的溫度連續上昇的方 式進行感應加熱的急速加熱模式、及藉由控制前述第2開 閉元件的開閉將前述整流輸出降壓地供給至前述變頻器將 前述馬桶座的溫度保持在預定溫度內的方式進行感應加熱 的保溫加熱模式。 [發明的效果] -6- 201244681 可提供一種由更簡易的構造就可以實現急速加熱及保 溫加熱加熱式馬桶座裝置。 依據本發明的一態樣的話，本發明可提供一種加熱式 馬桶座裝置，具備：設有感應加熱線圈及共振電容器的共 振電路；及藉由前述感應加熱線圈所發生的磁場被感應加 熱的導電體；及設有前述導電體的馬桶座；及具有第1開 閉元件並供控制供給至前述共振電路的電力用的變頻器·， 及將從商用電源被供給的電流整流的整流部；及具有第2 開閉元件並將前述整流部的整流輸出降壓地供給至前述變 頻器的降壓部；及控制部，實行：控制前述變頻器使前述 馬桶座的溫度連續上昇的方式進行感應加熱的急速加熱模 式、及藉由控制前述第2開閉元件的開閉將前述整流輸出 降壓地供給至前述變頻器將前述馬桶座的溫度保持在預定 溫度內的方式進行感應加熱的保溫加熱模式。 依據此加熱式馬桶座裝置的話，控制部，是在保溫加 熱模式，進行第2開閉元件的開閉控制，將整流輸出充分 地降壓地供給至變頻器。由此，控制部，不需將第1開閉 元件的導通（ON)時間等的共振動作變更，藉由降壓部將整 流輸出充分地降壓；就可抑制保溫加熱模式中的感應加熱 輸出比急速加熱模式中的感應加熱輸出更低。 因此，控制部，是使保溫加熱模式中的電力消耗量比 急速加熱模式中的電力消耗量更低，就可以將馬桶座的溫 度保持在預定溫度內。由此，沒有必要將急速加熱用的加 熱手段、及將保溫加熱用的加熱手段設成不同系統，由更 201244681 簡易的構造就可以實現急速加熱及保溫加熱。且，保溫加 熱模式的實行中，可以抑制馬桶座的溫度是急劇地上昇， 並抑制溫度不均勻發生。因此，可以抑制給與就坐在馬桶 座的使用者不舒服感。 且因爲整流輸出是藉由降壓部被充分地降壓，所以保 溫加熱模式中的共振電路的輸入電壓，是比急速加熱模式 中的共振電路的輸入電壓更低。因此，控制部各別實行急 速加熱模式及保溫加熱模式時，不需要變更第1開閉元件 的導通（ON)/斷開（OFF)的控制周期。控制部，是可以決定 適合由共振電路所產生的共振動作的動作條件的周期。 因此，即使保溫加熱模式中的共振振幅比急速加熱模 式中的共振振幅更小，共振電壓成爲零伏特的時間點仍會 存在。因此，控制部，是在保溫加熱模式中藉由進行零伏 特開閉動作就可以抑制開閉損失。 進一步，因爲整流輸出是藉由降壓部被充分地降壓， 所以在保溫加熱模式中流動於感應加熱線圈的電流，是比 在急速加熱模式中流動於感應加熱線圈的電流更小。因此 ，從感應加熱線圈所發生的漏出磁場被抑制，可以抑制對 於就坐在馬桶座的使用者的影響。 且依據本發明的一態樣的話，可提供一種加熱式馬桶 座裝置，前述急速加熱模式，是具有：前述控制部是將前 述第2開閉元件控制成連續導通（ON)的狀態，不使前述整

態’將整流輸出降壓地供給至變頻器使馬桶座的溫度連續 地上昇。另一方面’在第2急速加熱模式中，控制部，是 藉由進行第2開閉元件的開閉控制將整流輸出降壓地供給 至變頻器’使馬桶座的溫度連續地上昇。由此，控制部， 是在急速加熱模式的最初實行第1急速加熱模式，其後進 行第2急速加熱模式，或所要求的溫度上昇値較小時藉由 進行第2急速加熱模式，藉由降壓部控制急速加熱模式中 的馬桶座的溫度上昇速度，就可以抑制溫度過度上昇》 且依據本發明的一態樣的話，可提供一種加熱式馬桶 座裝置，前述控制部’是當實行前述保溫加熱模式時，藉 由前述降壓部將前述整流輸出降壓使比實行前述第2急速 加熱模式時電力消耗量更低。 依據此加熱式馬桶座裝置的話，整流輸出，是在保溫 加熱模式的實行時，藉由降壓部被降壓使電力消耗量比第 2急速加熱模式的實行時更充分地降低。由此，可以將保 溫加熱模式中的馬桶座的溫度穩定化，且可以更確實地抑 制漏出磁場。 且依據本發明的一態樣的話，可提供一種加熱式馬桶 座裝置’前述控制部，是當預定條件成立時就停止前述急 -9- 201244681 速加熱模式的實行’前述預定條件不成立時就實行前述保 溫加熱模式。 依據此加熱式馬桶座裝置的話，在加熱式馬桶座功能 成爲導通（ON)的狀態下，急速加熱模式的實行時期，是當 預定條件成立時被限制。且，當預定條件不成立時，控制 部是實行保溫加熱模式。由此，可以更提高安全性。 且依據本發明的一態樣的話，可提供一種加熱式馬桶 座裝置’進一步具備供檢出使用者朝前述馬桶座就坐的就 坐檢出感測器，前述控制部，是當前述就坐檢出感測器未 檢出前述就坐的條件成立時就實行前述急速加熱模式，當 前述就坐檢出感測器未檢出前述就坐的條件不成立時就實 行前述保溫加熱模式。 依據此加熱式馬桶座裝置的話，就坐檢出感測器若檢 出使用者是坐在馬桶座的話，控制部就實行保溫加熱模式 。由此，可以更提高對於就坐在馬桶座的使用者的安全性 〇 且依據本發明的一態樣的話，可提供一種加熱式馬桶 座裝置，進一步具備：可以將前述馬桶座覆蓋的馬桶蓋、 及將前述馬桶蓋的開閉狀態檢出的馬桶蓋開閉檢出感測器 ，前述控制部，是當前述馬桶蓋開閉檢出感測器檢出前述 馬桶蓋的閉狀態的條件成立時就實行前述急速加熱模式， 當前述馬桶蓋開閉檢出感測器檢出前述馬桶蓋的閉狀態的 條件不成立時就實行前述保溫加熱模式。 依據此加熱式馬桶座裝置的話’控制部’當馬桶蓋開 -10- 201244681 閉檢出感測器檢出馬桶蓋爲關閉的狀態時就 模式，當馬桶蓋開閉檢出感測器未檢出馬桶 態時就實行保溫加熱模式。因此，由控制部 急速加熱模式朝保溫加熱模式切換的時間，

裝置的廁所裝置的立體意示圖。 且第2圖，是顯示本實施例的馬桶座的意示圖。 又，第2圖（a)，是將本實施例的馬桶座從上方看的平 -12- 201244681 面意示圖，第2圖（b)，是如第2圖（a)所示的剖面A-A的 剖面意示圖。 如第1圖所示的廁所裝置，是具備：洋式座便器800 、及設在其上的加熱式馬桶座裝置100。加熱式馬桶座裝 置100，是具有：外殼400、及馬桶座200、及馬桶蓋300 。馬桶座200及馬桶蓋300，是對於外殼400可開閉自如 地各別被軸支。馬桶蓋3 00，是在關閉的狀態.可以將馬桶 座200的上方覆蓋。又，馬桶蓋300，不一定需要，不設 置也可以。 在外殻400中，設有：檢出使用者進入廁所的入室檢 出感測器402、及檢出使用者坐在馬桶座200的就坐檢出 感測器404、及檢出馬桶蓋300的開閉狀態的馬桶蓋開閉 檢出感測器406(第3圖參照）》 入室檢出感測器402，可以檢出：將廁所的門打開並 入室隨後的使用者、和欲進入廁所並存在於門前的使用者 。即，入室檢出感測器402，是不是只有進入廁所的使用 者，對於進入廁所之前的使用者，即存在於廁所外側的門 前的使用者也可以檢出。這種入室檢出感測器402，可以 使用：焦電感測器、和都卜勒（Doppler)感測器等的微波感 測器等。使用：利用微波的都卜勒（Doppler)效果的感測器 、和將微波發訊並依據被反射的微波的振幅（強度）檢出被 檢出體的感測器等的情況，在跨越廁所的門時就可檢出使 用者的存在。即，在進入廁所之前就可以檢出使用者。 就坐檢出感測器404，是例如，可以使用紅外線投受 -13- 201244681 光式的測距感測器等。馬桶蓋開閉檢出感測器406，是可 以使用例如霍爾（Hall)IC及磁鐵的組合，或微動開關等》 又，馬桶蓋開閉檢出感測器406，不限定於被內藏在 外殻400，設在馬桶蓋300的鉸鏈部和外殼400的外部也 可以。即，馬桶蓋開閉檢出感測器406，是可以將馬桶蓋 3 00的開閉狀態檢出即可。這對於就坐檢出感測器404及 入室檢出感測器402也同樣，就坐檢出感測器404及入室 檢出感測器402，不限定於被內藏在外殼400。即，就坐 檢出感測器404，是可以將使用者朝馬桶座200的就坐檢 出即可，入室檢出感測器402，是可以將使用者朝廁所的 入室檢出即可。例如，將入室檢出感測器402以別體安裝 在廁所的入口，藉由紅外線通訊將朝廁所的使用者的入室 傳達至外殼400內的控制部的方法也可以。 馬桶座200，是如第2圖（b)所示，具有形成馬桶座 200的外形的框體210。框體210，是由例如樹脂等的具有 絕緣性的材料形成。又，框體210，是由複數構件形成也 可以，由1個構件形成也可以。 在馬桶座200的框體210的內部，設有藉由高頻電流 通電而發生磁場的感應加熱線圈222。在如第2圖所示的 馬桶座200中，感應加熱線圈222，是被附設在馬桶座 200的內部的上面（相面對於就坐面的內面）210a。但是， 感應加熱線圈222的設置形態，不只限定於此，感應加熱 線圈222，是藉由被設在馬桶座200內部的無圖示的支撐 體被支撐也可以。 -14 - 201244681 在馬桶座200中，設有藉由從感應加熱線圈222發生 的磁場被感應加熱的導電體（發熱部）231°更具體而言’導 電體231，是藉著由從感應加熱線圈222發生的磁場被感 應的渦電流而發熱。導電體231’是被附設在馬桶座200 的上面（就坐面）。或是導電體23 1，是設在馬桶座200的 框體210的內部也可以。或是導電體231，是附設在馬桶 座200的內部的上面210a也可以。 導電體23 1，可以使用例如鐵和不鏽鋼等的強磁性體 ，或是鋁等的常磁性體的金屬。爲了使磁場不易放出馬桶 座200的外部，在導電體231使用電阻較大的鐵和不鏽鋼 等的強磁性體更佳。又，導電體231是設於馬桶座200的 上面的情況時，使人體及導電體231不會直接接觸的方式 ，在導電體231的表面施加塗裝和塗抹等更佳。 依據本實施例，加熱式馬桶座裝置1 〇〇，是利用感應 加熱的原理，可以將馬桶座200的就坐面急速加熱，可以 快速地使就坐面成爲適溫。且，本實施例的加熱式馬桶座 裝置100，因爲可以將馬桶座200的就坐面急速地加熱， 所以當使用者未使用馬桶座200時不需要將馬桶座200保 溫。因此，可以1抑制待機時的消耗電力，達成節能化。 另一方面，使用者就坐在馬桶座200之後即就坐在馬 桶座200時，有需要將馬桶座200的就坐面保溫在適溫。 例如’爲了將就坐面保溫設置加熱器作爲電力的電阻體的 話’急速加熱用的加熱手段（感應加熱手段）及保溫加熱用 的加熱手段（加熱器加熱手段）就需要設成不同系統。如此 -15- 201244681 的話，加熱式馬桶座裝置100的構造是成爲複雜，有可能 導致成本上昇。 對於此，本實施例的加熱式馬桶座裝置100，是將急 速加熱及保溫加熱藉由感應加熱實行。即，本實施例的加 熱式馬桶座裝置1 00，可以實行：使馬桶座200的就坐面 的溫度連續地上昇的方式進行感應加熱的急速加熱模式、 及將馬桶座200的就坐面的溫度保持在預定溫度內的方式 進行感應加熱的保溫加熱模式。由此，本實施例的加熱式 馬桶座裝置100，由更簡易的構造就可以實現急速加熱及 保溫加熱。 第3圖，是本實施例的加熱式馬桶座裝置的電路圖。 且第4圖，是本實施例的加熱式馬桶座裝置的其他的 電路圖。 例如，在外殼400內，設有：控制部410、及感應加 熱通電開關421、及電力消耗量檢出部430。控制部410， 是朝感應加熱通電開關42 1送出控制訊號。感應加熱通電 開關42 1，是藉由從控制部4 1 0送來的控制訊號來控制朝 高頻電源電路 500的通電的導通（ON)(導通（ON))/斷開 (OFF)(斷開（OFF))。電力消耗量檢出部430，是測量朝高 頻電源電路5 00的通電電流，藉由與商用電源10的電壓 乘算就可將被設在馬桶座200的導電體23 1的電力消耗量 間接地檢出。在控制部4 1 0及感應加熱通電開關42 1中， 連接有商用電源10。 在馬桶座2 00內，設有生成高頻電流並朝感應加熱線 -16- 201244681 圈222供給該高頻電流的高頻電源電路500。高頻電源電 路5 00，是具有：整流部510、及降壓部520、及平滑部 530、及共振電路540、及變頻器550。 整流部5 1 0，是將從商用電源1 0被供給的電流整流。 降壓部520，是斷路器式的降壓電路，具有：第2開 閉元件521、及二極體5 22、及降壓控制部5 23、及三角波 轉換部5 25、及比較器5 26、及平滑部5 3 0，將整流部510 的整流輸出降壓地供給至變頻器5 5 0。平滑部5 3 0中的平 滑線圈531及平滑電容器533，不只有作爲斷路器式降壓 電路的一部分的功能。平滑電容器533，也具有將流動於 變頻器5 5 0的高頻大電流平滑地供給的功能。平滑線圈 531，是對於高頻成爲高阻抗，也具有防止雜訊朝商用電 源1 〇側傳達的功能。又，線圈及電容器不兼用降壓功能 及平滑功能，而以線圈及電容器的組合各別串聯地連接也 可以。 共振電路540，是具有：感應加熱線圈222、及共振 電容器541。變頻器5 5 0，是具有第1開閉元件551，將供 給至共振電路540的電力控制。在第1開閉元件5 5 1中，使 用例如絕緣柵雙極晶體管（Insulated Gate Bipolar Transistor: IGBT)。 且在馬桶座200內，設有：輸出指示判別部25 1、及 動作/停止指示部25 3、及將馬桶座2 00的溫度檢出的熱敏 電阻（溫度感測器）2 5 5、及振盪控制部25 7。控制部410, 是朝輸出指示判別部25 1將輸出指示及降壓指示的控制訊 -17- 201244681 號發訊。輸出指示判別部2 5 1，是依據從控制部4 1 0被發 訊的控制訊號朝降壓控制部5 23將控制訊號發訊。降壓控 制部5 23，是依據從輸出指示判別部25 1被發訊的控制訊 號來控制第2開閉元件52 1的導通（ON)/斷開（OFF)。第2 開閉元件521，是依據從降壓.控制部523被發訊的控制訊 號來切換是否將整流部510的整流輸出降壓。輸出指示判 別部2 5 1，可以將輸出指示判別的狀態朝控制部4 1 0發訊 〇 動作/停止指示部2 5 3，是依據從輸出指示判別部251 被發訊的控制訊號朝振盪控制部2 5 7將控制訊號發訊。振 盪控制部25 7，是依據從動作/停止指示部25 3被發訊的控 制訊號來控制第1開閉元件551的導通（ON)/斷開（OFF)。 在動作/停止指示部2 5 3中，連接有熱敏電阻25 5 »動作/ 停止指示部2 5 3，是可以依據由熱敏電阻25 5檢出的馬桶 座2 00的溫度的資訊，透過振盪控制部2 5 7來控制第1開 閉元件55 1的導通（ON)/斷開（OFF)。由此，動作/停止指示 部25 3，可以控制馬桶座200的加熱時間和加熱特性，或 是高頻電源電路500的動作/停止。 如前述，控制部4 1 0，是朝輸出指示判別部25 1將加 熱指示輸出，透過動作/停止指示部25 3、及振盪控制部 25 7，控制第1開閉元件551的導通（ON)/斷開（OFF)。控 制部410，是只有進行感應加熱的導通（ON)/斷開（OFF)的 動作指示，進行第1開閉元件551的直接的導通（ON)/斷 開（OFF)的控制，是由振盪控制部25 7。振盪控制部25 7的 -18· 201244681 動作，是成爲如下。 首先，振盪控制部257是將第1開閉元件551控制成 導通（ON)狀態的話，從商用電源1〇被供給的電流，是藉 由整流部510被整流，藉由平滑部530被平滑化，流動於 感應加熱線圈2 2 2。此時，整流部5 1 0的整流輸出，是藉 由降壓部520的第2開閉元件521的開閉控制適宜被降壓 降壓動作，是在如第3圖所示的降壓部520藉由前饋 控制進行也可以，在如第4圖所示的降壓部520a藉由反 饋控制進行也可以。如第3圖所示的降壓部520是藉由前 饋控制將整流部5 1 0的整流輸出降壓情況時，例如使設想 以上的大電流流動的方式使高頻電源電路500動作，即使 平滑電容器533的電壓是異常下降時，也可由降壓部520 的輸入側的電壓進行降壓控制。因此，不會有使降壓部 520的輸出提高並進一步讓大電流流入的動作。因此，可 以更提高安全性。另一方面，如第4圖所示的降壓部520a 是藉由反饋控制將整流部510的整流輸出降壓的情況時， 例如商用電源1〇的電壓即使變動時，也可以抑制輸出的 變動而更穩定化。 電流流動於感應加熱線圈222的話，磁性能量會滞留 在感應加熱線圈2 2 2。接著，振盪控制部2 5 7是將第1開 閉元件551控制成斷開（OFF)狀態的話，電流不會從商用 電源10被供給，另一方面，滞留在感應加熱線圈222的 磁性能量會作爲靜電能量朝共振電容器5 4 1移動。其後， -19- 201244681 能量再度從共振電容器541朝感應加熱線圈222返回’而 共振。 在此共振動作的途中，藉由振盪控制部257控制使第 1開閉元件5 5 1再度成爲導通（ON)狀態的話’磁性能量會 被補充於感應加熱線圈222 ’反覆前述的動作使共振持續 〇 如此，振盪控制部2 5 7是藉由切換控制第1開,閉元件 551的導通（ON)狀態及斷開（OFF)狀態，使在感應加熱線 圈222及共振電容器541發生共振，使高頻電流生成。高 頻電流，是朝感應加熱線圈222被供給》感應加熱線圈 2 22，是藉由被供給的高頻電流使高頻磁場發生。藉由此 高頻磁場在導電體23 1發生渦電流，使導電體23 1發熱。 藉由以上的動作，控制部410，可以實行使馬桶座200的 就坐面的溫度連續地上昇的方式進行感應加熱的急速加熱 模式。例如，入室檢出感測器402若檢出使用者的入室的 話，控制部4 1 0，可以控制朝感應加熱線圈222的通電將 馬桶座200急速地加熱。因此，使用者坐在馬桶座200時 可以成爲不會感到寒冷的適溫。 接著，使用者就坐在馬桶座200之後即就坐在馬桶座 2 00時，是控制部410，是將保溫加熱的指示輸出來控制 第1開閉元件551的導通（ON)/斷開（OFF)，將馬桶座200 的就坐面的溫度保溫在預定溫度內。此時，振盪控制部 257只控制第1開閉元件551的導通（ON)/斷開（OFF)的話 ，在第1開閉元件5 5 1有可能發生過大的開閉損失。進一 -20- 201244681 步’有可能因開閉損失使第1開閉元件5 51被破壞。 接著，對於藉由感應加熱將馬桶座200的就坐面保溫 的情況時發生的課題及本實施例的加熱式馬桶座裝置100 的動作一邊參照圖面一邊說明。 第5圖，是說明比較例的加熱式馬桶座裝置的急速加 熱模式及保溫加熱模式用的時間圖。 且第6圖，是說明本實施例的加熱式馬桶座裝置的急 速加熱模式及保溫加熱模式用的時間圖。 且第7圖，是說明本實施例的加熱式馬桶座裝置的微 少加熱模式用的時間圖。 如第5圖（a)所示，振盪控制部2 5 7是將第1開閉元件 551控制成導通（ON)狀態的話，流動於感應加熱線圈222 的線圈電流IL會增加（時間點11 0 1)。由此，磁性能量會滯 留在感應加熱線圈222。接著，振盪控制部25 7是將第1 開閉元件551控制成斷開（OFF)狀態的話，使滞留在感應 加熱線圈222的磁性能量作爲靜電能量朝共振電容器54 1 移動（時間點tl02)。因此’共振電壓vCE會增加。又，共 振電壓VCE，是施加於第1開閉元件551的兩端的電壓。 接著’線圈電流IL是成爲零並朝相反方向流動開始的 話’共振電壓V c e會開始減少（時間點11 〇 3 )。即，共振電 容器541開始放電。且’共振電壓vCE，雖是以共振電路 5 40的輸入電壓（參照如第5圖（a)所示的虛線）爲基準欲振 動’但是因爲藉由被內藏在例如開閉元件551的續流二極 體5 5 2等被挾持’成爲幾乎零的狀態（時間點u〇4)。且， -21 - 201244681 在以上的動作中因爲在導電體231發生渦電流，使導電體 23 1發熱，所以共振能量會漸漸地衰減。 對於此，線圈電流U再度開始增加時，振盪控制部 25 7，是將第1開閉元件551控制成導通（ON)狀態（時間點 tl 05)。由此，能量再度滯留在感應加熱線圏222。 如此，由感應加熱線圈（L)222、及共振電容器（C)541 、及導電體（R)231所產生的LCR共振動作，使導電體231 發熱。因此，爲了抑制將馬桶座200的就坐面保溫時的感 應加熱輸出，有需要抑制共振動作的能量。共振動作的能 量，是由振動振幅（電流振幅）、及頻率決定。因此，控制 部4 1 0，是藉由將減小振動振幅或降低頻率使周期變慢的 開閉控制對於第1開閉元件5 5 1進行，就可以抑制感應加 熱輸出。 但是考慮例如藉由入室檢出感測器402檢出使用者的 入室來使控制部410控制朝感應加熱線圈222的通電來將 馬桶座200急速加熱的話，急速加熱模式中的感應加熱輸 出，是例如約1〇〇〇瓦以上較佳。另一方面，考慮將就坐 面的溫度保溫於使用者就坐在馬桶座200時不會感到寒冷 的預定溫度內的話，保溫加熱模式中的感應加熱輸出，是 例如約5 0瓦程度。即，在急速加熱模式及保溫加熱模式 之間，有更大的感應加熱輸出的差存在》 且感應加熱的實行時，存在由感應加熱線圏222及共 振電容器541的組合決定的共振頻率。一般，是由共振頻 率的附近的頻率進行第1開閉元件5 5 1的開閉控制。因此 -22- 201244681 ’爲了調整感應加熱輸出由任意的頻率進行第1開閉元件 5 5 1的開閉控制的話，會徧離共振動作。因此，藉由頻率 的調整控制比前述大的感應加熱輸出的差的話，有可能徧 離共振動作。 更具體說明的話，在保溫加熱模式中爲了抑制感應加 熱輸出使頻率比急速加熱模式更低時，必需比第1開閉元 件551的導通（ON)狀態的時間（以下爲了方便說明，稱爲 「導通（ON)時間」）更長。第1開閉元件551的導通（ON) 時間變長的話，線圈電流U會變更大。這會導致振動振幅 變大。因此，無法獲得抑制感應加熱輸出的效果。即，只 有降低頻率的話，無法將感應加熱輸出下降，有需要將感 應加熱線圈222和共振電容器54 1調整成對應較低頻率的 値。 另一方面，在保溫加熱模式中爲了抑制感應加熱輸出 考慮使振動振幅比急速加熱模式更小。如第5圖（b)及第5 圖（〇所示，第1開閉元件55 1的導通（ON)時間比急速加 熱模式更短的話，在保溫加熱模式就可以使振動振幅比急 速加熱模式更小。但是，第1開閉元件551的導通（ON)時 間比急速加熱模式更短的話，如第5圖（c)所示，具有第1 開閉元件5 5 1的開閉損失會成爲問題的情況。 在感應加熱方式的電路中，利用前述的共振動作的理 由之一，是在第1開閉元件551的電壓成爲0V(零伏特）的 時間點由振盪控制部25 7使第1開閉元件551成爲導通 (ON)狀態來抑制開閉損失。第5圖（a)如及第5圖（b)所示 -23- 201244681 的共振動作中的共振振幅，是比如第5圖（c)所示的共振動 作中的共振振幅更大。且，在如第5圖（a)及第5圖（b)所 示的共振動作中，存在第1開閉元件5 5 1的電壓即共振電 壓 VCE成爲零伏特的時間點（時間點tl04〜tl06、tl 14〜 tll6)。因此，在如第5圖（a)及第5圖（b)所示的共振動作 中，共振電壓VCE爲零伏特時藉著由控制部410使第1開 閉元件551成爲導通（ON)狀態（進行所謂的「零伏特開閉 動作」），就可以抑制開閉損失。 另一方面，如第5圖（c)所示的共振動作中的共振振幅 ’是比第5圖（a)如及第5圖（b)所示的共振動作中的共振 振幅更小。且，成爲共振電壓VCE的振動的基準的共振電 路540的輸入電壓，是與如第5圖（a)及第5圖（b)所示的 共振動作中的共振電路5 40的輸入電壓相同。因此，共振 電壓VCE，即使是以共振電路540的輸入電壓爲基準振動 ’也不會成爲零伏特。因此，振盪控制部2 5 7，即使是低 輸出的感應加熱動作中，爲了抑制共振能量的衰減使共振 動作持續，共振電壓VCE不是零伏特時有需要將第1開閉 元件551成爲導通（ON)狀態。即，在如第5圖（c)所示的 共振動作中，控制部4 1 0，是無法進行零伏特開閉動作。 如此的話，開閉損失會增大，第1開閉元件5 5 1有可能破 壞或燒損。 爲了避免開閉元件5 5 1的破壞，也考慮藉由控制部 4 1 〇將感應加熱動作間歇地進行來平均地抑制感應加熱輸 出，將馬桶座200的就坐面的溫度保溫在預定溫度內的方 -24- 201244681 法。但是，使用者的肌膚，會感到感應加熱動作的導通（ON) 及斷開（OFF)的反覆，而有可能感到不舒服感。 對於此，本實施例的控制部410，是對於輸出指示判 別部25 1將實行降壓的指示輸出，其結果，降壓控制部 5 23是進行第2開閉元件521的開閉控制，將整流部510 的整流輸出充分地降壓。即，控制部410，使用降壓部 5 2 0控制急速加熱模式及保溫加熱模式之間更大的感應加 熱輸出的差。 如第3圖所示的高頻電源電路500是被設在馬桶座 200內的情況時，降壓部520，可以藉由整流部510的整 流輸出的電壓即降壓部5 20的輸入電壓來決定第2開閉元 件521的導通（ON)時間的功率比。且，降壓部520，是降 壓部5 20的輸入電壓愈高，愈將第2開閉元件521的導通 (ON)時間的功率比決定成小的功率比。如此，降壓控制部 523，是對應降壓部520的輸入電壓決定功率比，就可以 實行不影響降壓部520的輸出電壓的前饋控制。由此，即 使例如使大電流流動的方式使高頻電源電路500動作時， 也可以由降壓部520的輸入側遮斷。例如，任何的異常動 作使感應加熱輸出增加，藉由朝變頻器550的輸入電壓即 降壓部5 20的輸出電壓下降，使降壓部520決定更大的功 率比，就可以迴避感應加熱輸出進一步增加。因此，可以 更提高安全性。 如前述，急速加熱模式中的感應加熱輸出是例如約 1000瓦程度’另一方面保溫加熱模式中的感應加熱輸出是 -25- 201244681 例如約5 0瓦程度。即，控制部4 1 0，是使保溫加熱模式中 的電力消耗量對於急速加熱模式中的電力消耗量成爲約 1/20〜1/10倍程度的方式控制降壓部520，將整流部510 的整流輸出充分地降壓》由此，可以將保溫加熱模式中的 馬桶座200的溫度穩定化，且可以更確實地抑制漏出磁場 。又，電力消耗量，是藉由電力消耗量檢出部430(第3圖 及第4圖參照）被檢出》 首先，如第6圖（a)所示，控制部410，是實行第1急 速加熱模式的情況時，將第2開閉元件52 1控制成連續導 通（ON)的狀態。由此，在第1急速加熱模式中，整流部 510的整流輸出，是在降壓部520未被降壓地被供給至變 頻器550。即，成爲整流後的商用電源10、及感應加熱線 圈222串接的狀態。控制部410，是可以將馬桶座200的 就坐面的溫度連續上昇地急速加熱。對於第1開閉元件 551、線圈電流IL及共振電壓VCE的動作或狀態，在第5 圖（a)中是與前述的第1開閉元件551、線圈電流IL及共振 電壓VCE的動作或狀態同樣。 如第6圖（b)所示，控制部410，是實行第2急速加熱 模式的情況時，進行第2開閉元件5 2 1的開閉控制。由此 ，在第2急速加熱模式中，整流部510的整流輸出，是在 降壓部520被降壓地被供給至變頻器5 5 0。在第2急速加 熱模式中，控制部410，也可以將馬桶座200的就坐面的 溫度連續上昇地急速加熱。 整流部510的整流輸出因爲是藉由降壓部5 20被降壓 -26- ⑧ 201244681 ’所以線圏電流IL，是比第1急速加熱模式中的線圏電流 U更小。即，第2急速加熱模式中的線圈電流U的振動振 幅，是比第1急速加熱模式中的線圈電流IL的振動振幅更 小。因此，第2急速加熱模式中的共振電壓VCE的共振振 幅，是比第1急速加熱模式中的共振電壓VCE的共振振幅 更小。且，第2急速加熱模式中的共振能量，是比第1急 速加熱模式中的共振能量更小。 控制部4 1 0，不需將共振動作（第1開閉元件的導通 (ON)時間和頻率等）變更，藉由將整流部510的整流輸出 由降壓部5 20降壓，就可以使第2急速加熱模式中的感應 加熱輸出比第1急速加熱模式中的感應加熱輸出更被抑制 。因此，控制部4 1 0，是藉由降壓部520控制急速加熱模 式中的馬桶座200的就坐面的溫度上昇速度，就可以抑制 溫度過度上昇。 整流部510的整流輸出因爲是在降壓部520被降壓， 所以成爲共振電壓VCE的振動的基準的共振電路540的輸 入電壓，是比第1急速加熱模式中的共振電路540的輸入 電壓更低。因此，即使第2急速加熱模式中的共振振幅是 比第1急速加熱模式中的共振振幅更小，共振電壓V c e成 爲零伏特的時間點仍存在（時間點t214〜t216)。因此，控 制部4 1 0，是藉由進行第2急速加熱模式零伏特開閉動作 ，就可以抑制開閉損失。 如第6圖（c)所示，控制部4 1 0，是實行保溫加熱模式 的情況時，與實行第2急速加熱模式的情況同樣地進行第 -27- 201244681 2開閉元件5 2 1的開閉控制的指示。且，控制部4 1 0，是 藉由降壓部5 20使整流部510的整流輸出比第1及第2急 速加熱模式中的整流輸出更充分地降壓。即，整流部5 1 0 的整流輸出，是在降壓部5 20比第1及第2急速加熱模式 中的整流輸出充分地被降壓地被供給至變頻器5 50。控制 部410，是可以將馬桶座200的就坐面的溫度保溫在預定 溫度內。 因爲整流部510的整流輸出是藉由降壓部520充分地 被降壓，所以線圈電流U，是比第1及第2急速加熱模式 中的線圈電流I L更小。即，保溫加熱模式中的線圈電流 II的振動振幅，.是比第1及第2急速加熱模式中的線圈電 流I L的振動振幅更小。因此，保溫加熱模式中的共振電壓 VCE的共振振幅，是比第1及第2急速加熱模式中的共振 電壓VCE的共振振幅更小》且，保溫加熱模式中的共振能 量，是比第1及第2急速加熱模式中的共振能量更小。 控制部4 1 0，是不需將共振動作變更，藉由將整流部 510的整流輸出藉由降壓部520充分地降壓，就可以使保 溫加熱模式中的感應加熱輸出比第1及第2急速加熱模式 中的感應加熱輸出更被抑制。因此，控制部4 1 0，可以將 電力消耗量比.第1及第2急速加熱模式中的電力消耗量更 低，並將馬桶座200的就坐面的溫度保溫在預定溫度內。 且，可以抑制馬桶座200的就坐面的溫度急劇地上昇，抑 制溫度不均勻發生。因此，可以抑制對於就坐在馬桶座 200的使用者給與不舒服感。 -28- 201244681 振盪控制部257，與第1及第2急速加熱模式相比較 ’不需要變更第1開閉元件551的導通（ON)/斷開（OFF)的 控制周期。振盪控制部2 5 7，不會被控制部4 1 0所指示的 感應加熱輸出的大小影響，可以決定適合由共振電路540 所產生的共振動作的動作條件的周期》 因爲整流部510的整流輸出是藉由降壓部520充分地 被降壓，所以成爲共振電壓VCE的振動的基準的共振電路 540的輸入電壓，是比第1及第2急速加熱模式中的共振 電路540的輸入電壓更低。因此，保溫加熱模式中的共振 振幅即使是比第1及第2急速加熱模式中的共振振幅更小 ，也存在共振電壓VCE成爲零伏特的時間點（時間點t224 〜t226)。因此，控制部410，是藉由在保溫加熱模式中進 行零伏特開閉動作就可以抑制開閉損失。 進一步’如第7圖所示，控制部4 1 〇，是與保溫加熱 模式同樣地將整流部510的整流輸出藉由降壓部52〇充分 地降壓’並且藉由使第1開閉元件551的導通（ON)時間比 第1及第2急速加熱模式以及保溫加熱模式更短，就可以 實行微少加熱模式。由此，在保溫加熱模式可獲得前述的 效果，並且可以達成進一步的節能化。 且因爲整流部510的整流輸出是藉由降壓部520充分 地被降壓，是否成爲共振電壓VCE的振動的基準的共振電 路5 40的輸入電壓，就會比第1及第2急速加熱模式中的 共振電路5 40的輸入電壓更低。因此，第1開閉元件55 i 的導通（ON)時間即使是比第1及第2急速加熱模式以及保 -29- 201244681 溫加熱模式中的導通（ON)時間更短，也存在共振電壓VcE 成爲零伏特的時間點（時間點12 3 4〜12 3 6)。因此，控制部 4 1 0，是藉由在保溫加熱模式中進行零伏特開閉動作就可 以抑制開閉損失。 第8圖’是說明本實施例的加熱式馬桶座裝置的降壓 動作及漏出磁場用的圖表。 從商用電源1 〇被供給的電流是藉由整流部5 1 0被整 流之後（全波整流後）的電源電壓，是如第8圖（a)所示。 如第8圖（b)所示，降壓控制部5 23，是藉由三角波轉 換部5 2 5 (第3圖參照）生成具有與如第8圖（a)所示的電源 電壓相同振幅的三角波。 接著，如第8圖（c)所示，將生成的三角波的電壓及預 定的電壓由比較器5 26比較，決定降壓部520的第2開閉 元件521的導通（ON)時間的功率比。如此的話，如第8圖 (d)所示，降壓部520的輸出電壓即共振電路540的輸入電 壓被限制》 由此，在第6圖（c)中如前述，保溫加熱模式中的線圈 電流II，是比第1及第2急速加熱模式中的槔圏電流IL 更小。即，保溫加熱模式中的線圈電流U的振動振幅，是 比第1及第2急速加熱模式中的線圈電流U的振動振幅更 小。因此，從感應加熱線圏222所發生的漏出磁場被抑制 ，可以抑制對於就坐在馬桶座200的使用者的影響》 又，在將感應加熱動作間歇地進行將平均的輸出下降 的保溫加熱模式的方法中，因爲感應加熱動作的瞬間的線 -30- 201244681 圈電流IL的振動振幅會變大，所以擔心影響就坐在馬桶 座200的使用者。 接著，對於本實施例的加熱式馬桶座裝置100的動作 的具體例，一邊參照圖面一邊說明。 第9圖，是顯示本實施例的加熱式馬桶座裝置的動作 的具體例的時間圖。 首先，在入室檢出感測器402檢出使用者的入室之前 ，馬桶座200的就坐面的溫度，是室溫，未被保溫於使用 者不會感到寒冷的預定溫度內（時間點t3 01以前）。接著， 入室檢出感測器402若檢出使用者的入室的話，控制部 410，是將第2開閉元件521控制成連續導通（ON)的狀態 ，將第1開閉元件55 1的開閉控制的開始指示輸出並實行 急速加熱模式（時間點t301)。由此，馬桶座200的就坐面 ，是呈連續溫度上昇地被急速加熱。 接著，馬桶座200的就坐面的溫度是成爲適溫（目標 溫度和設定溫度等）的話，控制部4 1 0，是進行第2開閉元 件52 1的開閉控制，使整流部5 1 0的整流輸出比急速加熱 模式中的整流輸出更降壓地實行保溫加熱模式（時間點 t3 02)。由此，馬桶座200的就坐面，可被保溫在使用者不 會感到寒冷的適溫即預定溫度內。換言之，將馬桶座200 的就坐面保溫的加熱量、及來自馬桶座20 0的放熱量，是 呈熱平衡的溫度而穩定。 接著，使用者藉由手動將馬桶蓋3 00打開的話，或是 藉由無圖示的遙控器等的操作打開的話，馬桶蓋開閉檢出 -31 - 201244681 感測器406，是檢出馬桶蓋3 00開始打開（時間點t3 03 )， 並檢出馬桶蓋3 00爲關閉的狀態及打開的狀態之間的中間 狀態（時間點t3 03〜t304)。接著，馬桶蓋開閉檢出感測器 4〇6，是檢出馬桶蓋300打開的狀態（時間點t304)。又， 入室檢出感測器402若檢出使用者的入室的話，控制部 41〇，是藉由無圖示的馬桶蓋開閉驅動部等實行將馬桶蓋 3 〇〇自動地打開的控制也可以。 接著，使用者就坐在馬桶座200的話，就坐檢出感測 器404，是檢出使用者已坐在馬桶座200(時間點t3 05)。 且’使用者從馬桶座200離座的話，就坐檢出感測器404 ’是檢出使用者未坐在馬桶座200(時間點t3 06)。 接著，使用者是將馬桶蓋3 00藉由手動關閉的話，或 是藉由無圖示的遙控器等的操作關閉的話，馬桶蓋開閉檢 出感測器406，是檢出馬桶蓋300開始關閉（時間點t307) ，檢出馬桶蓋3 00打開的狀態及關閉的狀態之間的中間的 狀態（時間點t3 07〜t3 08)。接著，馬桶蓋開閉檢出感測器 4 06 ’是檢出馬桶蓋300關閉的狀態（時間點t3 0 8)。又， 入室檢出感測器402若檢出使用者的退室的話，控制部 4 1 〇 ’是藉由無圖示的馬桶蓋開閉驅動部等實行將馬桶蓋 3 00自動地關閉的控制也可以（時間點t3 09之後）。 接著，入室檢出感測器402若檢出使用者的退室的話 ’控制部410，就停止第2開閉元件521的開閉控制，將 第1開閉元件5 5 1的開閉控制的停止指示輸出將保溫加熱 模式停止（時間點t309)。即，控制部410，是將馬桶座 -32- 201244681 200的加熱停止。因此，馬桶座200的就坐面的溫度，是 漸漸地下降（時間點t3 09之後）。 依據本具體例的話，入室檢出感測器402若檢出使用 者的入室的話，控制部4 1 0，就實行急速加熱模式，可以 藉由感應加熱將馬桶座200的就坐面急速地加熱。由此， 使用者未使用馬桶座200時沒有必要將馬桶座200保溫， 就可以抑制待機時的消耗電力，達成節能化。且，馬桶座 200的就坐面的溫度是成爲適溫的話，控制部410就實行 保溫加熱模式，使可以藉由感應加熱將馬桶座200的就坐 面的溫度保溫在預定溫度內。由此，沒有必要將急速加熱 用的加熱手段、及將保溫加熱用的加熱手段設成不同系統 ，由更簡易的構造就可以實現急速加熱及保溫加熱。 第10圖，是顯示本實施例的加熱式馬桶座裝置的動 作的其他的具體例的時間圖。 入室檢出感測器402檢出使用者的入室之前的動作， 是與第9圖的前述的具體例中的時間點t3 0 1以前的動作 同樣（時間點t31 1以前）。 接著，入室檢出感測器402若檢出使用者的入室的話 ，控制部410，是將第2開閉元件521控制成連續導通（ON) 的狀態，將第1開閉元件55 1的開閉控制的開始指示輸出 並實行第1急速加熱模式（時間點t3 1 1)。由此，馬桶座 200的就坐面，是呈連續溫度上昇地被急速加熱。 接著，馬桶座200的就坐面的溫度是上昇至比適溫低 例如3 °C的溫度的話，控制部4 10，是就進行第2開閉元 -33- 201244681 件5 2 1的開閉控制，將整流部5 1 0的整流輸出降壓地實行 第2急速加熱模式（時間點13 1 2)。由此，第2急速加熱模 式中的感應加熱輸出，是比第1急速加熱模式中的感應加 熱輸出更被抑制。因此，如第10圖所示，第2急速加熱 模式中的馬桶座200的就坐面的溫度的上昇率（上昇速度） ’是比第1急速加熱模式中的馬桶座2 0 0的就坐面的溫度 的上昇率更低（時間點t3 12〜t3 13)。 在第2急速加熱模式中，控制部4 1 0，也可以將馬桶 座200的就坐面的溫度連續上昇地急速加熱。又，控制部 410從第1急速加熱模式切換至第2急速加熱模式的時間 點，不限定於馬桶座2 0 0的就坐面的溫度上昇至比適溫更 低3 °C的溫度時。對於成爲加熱模式的切換的時間點的溫 度差（本具體例爲3°C)，是可以適宜變更。 接著，馬桶座200的就坐面的溫度是成爲適溫的話， 控制部4 1 0 ’是改變第2開閉元件5 2 1的開閉控制的條件 ’具體而言減小第2開閉元件521的導通（ON)時間的功率 比’將整流部510的整流輸出比第1及第2急速加熱模式 中的整流輸出更降壓地實行保溫加熱模式（時間點13 1 3 )。 由此，馬桶座200的就坐面，可被保溫在使用者不會感到 寒冷的適溫即預定溫度內。接著，時間點t314〜t32〇的動 作’是與第9圖的前述的具體例中的時間點t3〇3〜t309的 動作同樣。 依據本具體例的話’急速加熱模式，是具有：第1急 速加熱模式、及第2急速加熱模式。在第1急速加熱模式 -34- 201244681 中’控制部4 1 0，是將第2開閉元件5 2 1控制成連續導通 (ON)的狀態，將整流部510的整流輸出降壓地供給至變頻 器550。另一方面，在第2急速加熱模式中，控制部410 ，是進行第2開閉元件52 1的開閉控制，將整流部5 1 0的 整流輸出降壓地供給至變頻器5 5 0。由此，控制部4 1 0， 是藉由降壓部520控制急速加熱模式中的馬桶座200的就 坐面的溫度上昇速度，可以抑制溫度過度上昇。 在以下的具體例中，預定條件成立時急速加熱模式被 實行，預定條件不成立時保溫加熱模式被實行。即，急速 加熱模式的實行時期，當預定條件成立時會被限制。 第1 1圖，是顯示本實施例的加熱式馬桶座裝置的動 作的其他的具體例的時間圖。 在本具體例中，使用者未就坐在馬桶座200時急速加 熱模式被實行，使用者就坐在馬桶座200時保溫加熱模式 被實行。即，在使用者就坐中，急速加熱模式的實行被抑 止。本具體例的動作，是對於：加熱式馬桶座裝置1 00未 具有馬桶蓋3 00的情況、和未設有馬桶蓋開閉檢出感測器 406的情況、和馬桶蓋開閉檢出感測器406故障而將馬桶 蓋3 00打開的狀態辨認成關閉的狀態的情況等有效的動作 之一。 入室檢出感測器402檢出使用者的入室之前的動作，

Description of the Invention: [Technical Field] The present invention relates to a heated toilet seat apparatus that can warm a toilet seat provided in a toilet. . [Prior Art] In many heating toilet seat devices, for example, a heater or the like as an electric heating body is provided inside the toilet seat. When the current flows through the heater, the temperature of the surface of the toilet seat is raised by the heat conduction of the Joule heat generated in the heater. For example, in the case where the toilet seat is formed of a resin, since the thermal resistance of the resin is large, it takes tens of seconds to several minutes in order to raise the temperature of the surface of the toilet seat to the target temperature. Therefore, in order to allow the user to feel cold when sitting in the toilet seat, it is necessary to warm the heater to warm the surface of the toilet seat even when the user is not seated in the toilet seat. Therefore, there is still room for improvement in terms of suppressing power consumption during standby and achieving energy saving. In this case, a toilet seat heating device includes a heater and an electromagnetic induction heating coil (Patent Document 1). In the toilet seat heating device of Patent Document 1, when the toilet is detected, the electromagnetic induction heating wire is activated to instantaneously heat the toilet seat. Further, it is heated by the heater after sitting in the toilet seat. However, if the heating means for instantaneous heating or rapid heating and the heating means for heat preservation and heating are provided in different systems, there is a problem that the structure becomes complicated and the cost increases. [PRIOR ART DOCUMENT] - 5 - 201244681 [Patent Document 1] [Patent Document 1] JP-A-2008-1081 1 4 SUMMARY OF THE INVENTION [Problems to be Solved by the Invention] The present invention is based on the above The purpose of the subject is to provide a heated toilet seat device that can be rapidly heated and insulated by a simpler construction. [Means for Solving the Problem] The present invention can provide a heated toilet seat apparatus comprising: a resonance circuit provided with an induction heating coil and a resonance capacitor; and an electric conductor inductively heated by a magnetic field generated by the induction heating coil And a toilet seat provided with the electric conductor; and a frequency converter having a first opening and closing element for controlling power supplied to the resonance circuit; and a rectifying unit for rectifying a current supplied from the commercial power source; and having a second The switching element supplies the step-down device to the step-down unit of the inverter in a step-down manner, and the control unit performs a rapid heating mode in which the inverter is controlled to continuously increase the temperature of the toilet seat. And an insulation heating mode in which induction heating is performed by controlling the opening and closing of the second opening and closing element to supply the rectification output to the inverter to maintain the temperature of the toilet seat at a predetermined temperature. [Effects of the Invention] -6-201244681 It is possible to provide a rapid heating and temperature-heating heated toilet seat device with a simpler construction. According to an aspect of the present invention, the present invention provides a heated toilet seat apparatus comprising: a resonance circuit provided with an induction heating coil and a resonance capacitor; and a conductively induced heating by a magnetic field generated by the induction heating coil And a toilet seat provided with the electric conductor; and a frequency converter for controlling electric power supplied to the resonance circuit and having a first opening and closing element; and a rectifying unit for rectifying a current supplied from the commercial power source; a second opening/closing element that supplies the rectified output of the rectifying unit to the step-down unit of the inverter in a step-down manner; and the control unit performs a rapid control of the induction heating by controlling the inverter to continuously increase the temperature of the toilet seat The heating mode and the insulation heating mode in which the rectification output is stepped down by controlling the opening and closing of the second opening and closing element to the inverter to maintain the temperature of the toilet seat at a predetermined temperature. According to the above-described heated toilet seat device, the control unit performs the opening and closing control of the second opening and closing element in the heat insulating mode, and supplies the rectified output to the inverter in a sufficiently step-down manner. Therefore, the control unit does not need to change the resonance operation of the ON/OFF time of the first switching element, and the step-down unit sufficiently reduces the rectification output, thereby suppressing the induction heating output ratio in the heat retention heating mode. The induction heating output in the rapid heating mode is lower. Therefore, the control unit can maintain the temperature of the toilet seat at a predetermined temperature by lowering the power consumption amount in the heat retention heating mode than the power consumption amount in the rapid heating mode. Therefore, it is not necessary to set the heating means for rapid heating and the heating means for heat preservation and heating to different systems, and it is possible to realize rapid heating and heat preservation by the simple structure of 201244681. Further, in the practice of the heat retention heating mode, it is possible to suppress the temperature of the toilet seat from rising sharply and suppress the occurrence of temperature unevenness. Therefore, it is possible to suppress the discomfort of the user who is sitting in the toilet seat. Further, since the rectified output is sufficiently stepped down by the step-down portion, the input voltage of the resonant circuit in the warm-up heating mode is lower than the input voltage of the resonant circuit in the rapid heating mode. Therefore, when the control unit performs the rapid heating mode and the heat retention heating mode, it is not necessary to change the control period of the ON/OFF of the first switching element. The control unit is a period that can determine the operating conditions suitable for the resonant operation generated by the resonant circuit. Therefore, even if the resonance amplitude in the heat retention heating mode is smaller than the resonance amplitude in the rapid heating mode, the resonance voltage becomes zero volts at the time point. Therefore, the control unit can suppress the opening and closing loss by performing the zero-volt opening and closing operation in the heat retention heating mode. Further, since the rectified output is sufficiently stepped down by the step-down portion, the current flowing in the induction heating coil in the heat retention heating mode is smaller than the current flowing in the induction heating coil in the rapid heating mode. Therefore, the leakage magnetic field generated from the induction heating coil is suppressed, and the influence on the user sitting on the toilet seat can be suppressed. According to another aspect of the present invention, there is provided a heated toilet seat apparatus, wherein the rapid heating mode has a state in which the control unit controls the second opening and closing element to be continuously turned ON (ON), and does not cause the foregoing a first rapid heating mode in which the rectification output is supplied to the inverter to continuously increase the temperature of the toilet seat, and the control unit is controlled to open and close the second opening and closing element. The second rapid heating mode in which the rectification output is stepped down to the inverter to continuously increase the temperature of the toilet seat. In the first rapid heating mode, the 'control unit' controls the second opening and closing element to be continuously turned on (0N) in the first rapid heating mode, and supplies the rectified output to the inverter in a step-down manner to the toilet seat. The temperature rises continuously. On the other hand, in the second rapid heating mode, the control unit supplies the inverter output to the inverter in a step-down manner by performing the opening and closing control of the second opening and closing element to continuously increase the temperature of the toilet seat. Therefore, the control unit performs the first rapid heating mode at the beginning of the rapid heating mode, and then performs the second rapid heating mode, or when the required temperature rise 値 is small, by performing the second rapid heating mode. The step-down unit controls the temperature rise rate of the toilet seat in the rapid heating mode to suppress excessive temperature rise. According to an aspect of the present invention, a heated toilet seat device can be provided, wherein the control unit is configured to perform the foregoing In the heat retention heating mode, the rectification output is stepped down by the step-down unit to lower the power consumption amount when the second rapid heating mode is executed. According to the above-described heated toilet seat device, the rectification output is lowered in the heat-insulation heating mode, and the pressure-reduction portion is stepped down so that the power consumption amount is more sufficiently lowered than the execution of the second rapid heating mode. Thereby, the temperature of the toilet seat in the heat retention heating mode can be stabilized, and the leakage magnetic field can be more reliably suppressed. According to an aspect of the present invention, a heating type toilet seat apparatus "the control unit is provided, and when the predetermined condition is satisfied, the execution of the emergency -9-201244681 speed heating mode is stopped, and the predetermined condition is not established. The aforementioned heat preservation mode. According to the heated toilet seat device, in the state where the heated toilet seat function is turned ON, the execution period of the rapid heating mode is restricted when the predetermined condition is satisfied. Further, when the predetermined condition is not satisfied, the control unit performs the heat retention heating mode. Thereby, the safety can be further improved. According to an aspect of the present invention, a heated toilet seat apparatus is further provided, further comprising a sitting detection sensor for detecting that the user sits on the toilet seat, and the control unit is configured to detect the sitting position. The rapid heating mode is executed when the detector does not detect that the sitting condition is satisfied, and the insulation heating mode is executed when the condition that the sitting detection sensor does not detect the sitting is not satisfied. According to the heated toilet seat device, if the sensor is detected and the user is sitting in the toilet seat, the control unit performs the heat insulation heating mode. Thereby, the safety of the user sitting on the toilet seat can be further improved, and according to an aspect of the present invention, a heated toilet seat device can be further provided, further comprising: a toilet cover that can cover the toilet seat, And a toilet lid opening and closing detecting sensor that detects the opening and closing state of the toilet lid, wherein the control unit performs the aforementioned when the condition that the toilet lid opening and closing detecting sensor detects the closed state of the toilet lid is satisfied In the rapid heating mode, the aforementioned heat retention heating mode is executed when the condition that the toilet lid opening and closing detection sensor detects that the toilet lid is closed is not established. According to the heated toilet seat device, the 'control unit' is in the mode when the toilet cover is opened -10- 201244681. When the sensor detects that the toilet cover is closed, the sensor is not detected when the toilet cover is opened and closed. Insulation heating mode is implemented in the toilet state. Therefore, the period from the time when the control unit rapid heating mode is switched to the heat retention heating mode, and the period from the start of the opening to the open state can be improved for the safety of the user sitting in the toilet seat, and according to an aspect of the present invention, Provided is a device, further comprising: a toilet cover that can detect the opening and closing state of the toilet lid, and the control unit is configured to open and close the toilet lid to detect an open state of the toilet lid When the toilet lid opening and closing detection sensor does not detect the condition of the state is not established, the heat insulation heating mode is executed. According to the heating toilet seat device, the control unit detects that the sensor is not detected. When the toilet lid is in the open state, the heat mode is applied when the toilet lid is opened and closed to detect that the sensor detects the toilet state. Therefore, the control unit can continue to approach the temperature of the toilet seat until the toilet seat is fully opened. As a result, it is possible to feel cold when sitting in the toilet seat. According to still another aspect of the present invention, a device can be provided, wherein the step-down portion is a power ratio corresponding to a turn-on (ON) time of the rectifying output 2 switching element, and the power ratio is determined to be smaller. Perform a rapid heating cover that is closed. The heating mode is from the toilet cover. Therefore, sex. The toilet lid of the heated toilet lid, the closed detector sensor is not detected, and the open lid of the rapid heating mode toilet lid is not detected. When the toilet lid is opened, the quick capping is opened to start to open until the heating mode is fast. The grounding device suppresses the user's heated toilet to determine the higher the rectified output. -11 - 201244681 According to the heated toilet seat device, the control unit determines the conduction (〇N) time of the second opening and closing element in accordance with the rectification output. The power ratio can be implemented with feedforward control that does not affect the output voltage of the rectifier. Therefore, security can be improved. According to an aspect of the present invention, a heating toilet seat device can be further provided with a temperature sensor for detecting the temperature of the toilet seat, and the control unit, when the temperature of the temperature sensor is detected. When the predetermined value is higher than the predetermined value, the second opening and closing element is controlled to be in an OFF state. According to the heated toilet seat apparatus, the control unit controls the second opening and closing element to be in an OFF state when the temperature detected by the temperature sensor is higher than a predetermined value. Therefore, the second opening and closing element has a function as a safety device. In other words, the control unit can control the second opening and closing element to be in an OFF state and block the energization of the induction heating coil. Therefore, security can be further improved. [Embodiment] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The entrance detection sensor 402 can detect: the user opening the door of the toilet into the room, and the user who wants to enter the toilet and exists in front of the door User. That is, the entrance detecting sensor 402 is only a user who enters the toilet, and can be detected by a user who has entered the toilet, that is, a user who exists in front of the door outside the toilet. Such an entrance detecting sensor 402 can be used, for example, a focal inductance detector, a microwave sensor such as a Doppler sensor, or the like. Use: a sensor using a Doppler effect of microwaves, and a sensor that detects a detected body based on the amplitude (intensity) of the reflected microwave and the microwave, and crosses the toilet The presence of the user can be detected at the door. That is, the user can be detected before entering the toilet. The sensor 404 is detected, for example, an infrared ray-sensing sensor, etc., can be used. The toilet lid opening and closing detecting sensor 406 can use, for example, a combination of a Hall IC and a magnet, or a micro switch, etc. Further, the toilet lid opening and closing detecting sensor 406 is not limited to being housed in the outer casing. 400 may be provided on the hinge portion of the toilet lid 300 and the outside of the outer casing 400. In other words, the toilet lid opening and closing detection sensor 406 can detect the opening and closing state of the toilet lid 300. Similarly, the sitting detection sensor 404 and the entrance detecting sensor 402 are similarly positioned, and the detecting sensor 404 and the entrance detecting sensor 402 are not limited to being housed in the casing 400. That is, the sensor 404 is detected and the user can be detected by sitting on the toilet seat 200. The entrance detecting sensor 402 can detect the user entering the toilet. For example, a method in which the entrance detecting sensor 402 is attached to the entrance of the toilet and the toilet entering the room to the control unit in the casing 400 by infrared communication may be used. The toilet seat 200 has a casing 210 that forms the outer shape of the toilet seat 200 as shown in Fig. 2(b). The casing 210 is formed of an insulating material such as a resin. Further, the casing 210 may be formed of a plurality of members, and may be formed of one member. Inside the casing 210 of the toilet seat 200, an induction heating coil 222 that generates a magnetic field by energization of a high-frequency current is provided. In the toilet seat 200 shown in Fig. 2, the induction heating coil 222 is attached to the upper surface of the toilet seat 200 (opposite to the inner surface of the seating surface) 210a. However, the form of the induction heating coil 222 is not limited thereto, and the induction heating coil 222 may be supported by a support (not shown) provided inside the toilet seat 200. -14 - 201244681 In the toilet seat 200, a conductor (heat generating portion) 231 which is inductively heated by a magnetic field generated from the induction heating coil 222 is provided, more specifically, the electric conductor 231 is heated by induction. The magnetic field generated by the coil 222 is heated by the induced eddy current. The electric conductor 231' is attached to the upper surface (the seating surface) of the toilet seat 200. Alternatively, the electric conductor 23 1 may be provided inside the casing 210 of the toilet seat 200. Alternatively, the conductor 231 may be an upper surface 210a attached to the inside of the toilet seat 200. As the conductor 23 1, a ferromagnetic body such as iron or stainless steel or a metal of a normal magnetic body such as aluminum can be used. In order to make it difficult for the magnetic field to be released outside the toilet seat 200, it is preferable to use a ferromagnetic body such as iron and stainless steel having a large electric resistance in the electric conductor 231. Further, when the conductor 231 is provided on the upper surface of the toilet seat 200, it is preferable to apply coating and smearing to the surface of the conductor 231 so that the human body and the conductor 231 are not in direct contact with each other. According to the present embodiment, the heated toilet seat apparatus 1 is based on the principle of induction heating, and the seating surface of the toilet seat 200 can be rapidly heated, so that the sitting surface can be quickly warmed. Further, in the heated toilet seat apparatus 100 of the present embodiment, since the seating surface of the toilet seat 200 can be rapidly heated, it is not necessary to keep the toilet seat 200 warm when the user does not use the toilet seat 200. Therefore, it is possible to suppress the power consumption during standby and to achieve energy saving. On the other hand, when the user sits on the tub base 200 after sitting on the toilet seat 200, it is necessary to keep the sitting surface of the toilet seat 200 at a suitable temperature. For example, the heating means (induction heating means) for rapid heating and the heating means (heater heating means) for heat preservation heating are required to be provided in a different system in order to provide a heater as a resistor for electric power. In the case of -15-201244681, the structure of the heated toilet seat apparatus 100 is complicated, which may cause an increase in cost. In this regard, the heated toilet seat apparatus 100 of the present embodiment performs rapid heating and heat preservation heating by induction heating. That is, the heated toilet seat apparatus 100 of the present embodiment can perform a rapid heating mode in which induction heating is performed so that the temperature of the seating surface of the toilet seat 200 continuously rises, and the temperature of the seating surface of the toilet seat 200 is maintained. An insulation heating mode in which induction heating is performed in a predetermined temperature. Thus, the heated toilet seat apparatus 100 of the present embodiment can realize rapid heating and heat preservation heating by a simpler structure. Fig. 3 is a circuit diagram of the heated toilet seat apparatus of the present embodiment. Further, Fig. 4 is another circuit diagram of the heated toilet seat apparatus of the present embodiment. For example, the casing 400 is provided with a control unit 410, an induction heating power-on switch 421, and a power consumption amount detecting unit 430. The control unit 410 sends a control signal to the induction heating power switch 42 1 . The induction heating power switch 42 1 controls ON (ON) / OFF (OFF) of energization to the high-frequency power supply circuit 500 by a control signal sent from the control unit 410. ON (OFF)). The power consumption amount detecting unit 430 measures the current flowing to the high-frequency power source circuit 500, and by multiplying the voltage of the commercial power source 10, the power consumption of the conductor 23 1 provided in the toilet seat 200 can be indirectly Check out. The commercial power source 10 is connected to the control unit 401 and the induction heating power switch 42 1 . In the toilet seat 200, a high-frequency power supply circuit 500 that generates a high-frequency current and supplies the high-frequency current to the induction heating line -16 - 201244681 circle 222 is provided. The high-frequency power supply circuit 5 00 includes a rectifying unit 510, a step-down unit 520, a smoothing unit 530, a resonance circuit 540, and a frequency converter 550. The rectifying unit 510 is rectifying the current supplied from the commercial power source 10. The step-down unit 520 is a circuit breaker type step-down circuit, and includes a second opening and closing element 521, a diode 52, a step-down control unit 523, a triangular wave conversion unit 525, and a comparator 526. And the smoothing unit 530 returns the rectified output of the rectifying unit 510 to the inverter 550 in a step-down manner. The smoothing coil 531 and the smoothing capacitor 533 in the smoothing portion 530 are not only functions as a part of the circuit breaker type step-down circuit. The smoothing capacitor 533 also has a function of smoothly supplying a high-frequency large current flowing through the inverter 550. The smoothing coil 531 has a function of preventing high-frequency from being high-frequency and preventing noise from being transmitted to the side of the commercial power source 1. Further, the coil and the capacitor do not have a step-down function and a smoothing function, and a combination of a coil and a capacitor may be connected in series. The resonance circuit 540 has an induction heating coil 222 and a resonance capacitor 541. The inverter 550 has the first opening and closing element 551 and controls the electric power supplied to the resonance circuit 540. In the first opening and closing element 515, for example, an insulated gate bipolar transistor (IGBT) is used. Further, in the toilet seat 200, an output instruction determining unit 25 1 and an operation/stop instructing unit 25 3 and a thermistor (temperature sensor) for detecting the temperature of the toilet seat 200 are provided. And an oscillation control unit 257. The control unit 410 transmits a control message to the output instruction determining unit 25 1 to output an instruction and a step-down instruction. The output instruction determining unit 251 sends a control signal to the step-down control unit 523 in accordance with a control signal transmitted from the control unit 410. The step-down control unit 523 controls the ON/OFF of the second switching element 52 1 in accordance with the control signal transmitted from the output instruction determining unit 25 1 . The second opening and closing element 521 is based on the buck. The control unit 523 switches whether or not the rectified output of the rectifying unit 510 is stepped down by the control signal that is signaled. The output instruction determination unit 251 can issue a state in which the output instruction is determined to the control unit 4 1 0. The operation/stop instruction unit 253 is controlled by the control signal from the output instruction determination unit 251 toward the oscillation control. Department 2 5 7 will send control signals. The oscillation control unit 25 7 controls the ON/OFF of the first switching element 551 in accordance with the control signal transmitted from the operation/stop instruction unit 253. In the operation/stop instruction unit 253, a thermistor 25 5 »action/stop instruction unit 253 is connected, and the information can be transmitted based on the temperature of the toilet seat 200 detected by the thermistor 25 5 . The oscillation control unit 257 controls the ON/OFF of the first switching element 55 1 . Thereby, the operation/stop instruction unit 25 3 can control the heating time and heating characteristics of the toilet seat 200 or the operation/stop of the high-frequency power source circuit 500. As described above, the control unit 401 outputs the heating instruction to the output instruction determining unit 25 1 , and the transmission operation/stop instruction unit 25 3 and the oscillation control unit 25 7 control the ON/OFF of the first opening/closing element 551. Disconnected (OFF). The control unit 410 is an operation instruction for ON/OFF of the induction heating only, and performs direct ON/OFF control of the first switching element 551, and is controlled by oscillation. Department 25 7. The operation of -18·201244681 of the oscillation control unit 25 7 is as follows. First, when the oscillation control unit 257 controls the first switching element 551 to be in an ON state, the current supplied from the commercial power source 1 is rectified by the rectifying unit 510 and smoothed by the smoothing unit 530. Flows through the induction heating coil 2 2 2 . At this time, the rectification output of the rectifying unit 510 is appropriately stepped down and down by the opening and closing control of the second opening and closing element 521 of the step-down unit 520, and is borrowed from the step-down unit 520 as shown in FIG. The feedforward control may be performed, and the step-down unit 520a as shown in Fig. 4 may be performed by feedback control. When the step-down control unit 520 is configured to reduce the rectification output of the rectifying unit 5 10 by the feedforward control, the high-frequency power supply circuit 500 is operated even if the above-described large current is assumed to flow, for example. When the voltage of the smoothing capacitor 533 is abnormally dropped, the voltage on the input side of the step-down unit 520 can be step-down controlled. Therefore, there is no operation for increasing the output of the step-down unit 520 and further allowing a large current to flow. Therefore, safety can be improved. On the other hand, when the step-down unit 520a shown in FIG. 4 is configured to reduce the rectified output of the rectifying unit 510 by feedback control, for example, even if the voltage of the commercial power source 1 变动 changes, the output fluctuation can be suppressed. It is more stable. When current flows through the induction heating coil 222, the magnetic energy is retained in the induction heating coil 2 2 2 . When the oscillation control unit 257 controls the first opening and closing element 551 to be in the OFF state, the current is not supplied from the commercial power source 10, and the magnetic energy remaining in the induction heating coil 222 is used as the magnetic energy. The electrostatic energy moves toward the resonance capacitor 5 4 1 . Thereafter, -19-201244681 energy is again returned from the resonance capacitor 541 toward the induction heating coil 222 and resonates. In the middle of the resonance operation, when the oscillation control unit 257 controls the first opening/closing element 515 to be turned ON again, the magnetic energy is added to the induction heating coil 222' to repeat the above operation to continue the resonance. In this manner, the oscillation control unit 257 switches the ON state and the OFF state of the closing element 551 by switching, and causes the induction heating coil 222 and the resonance capacitor 541 to resonate to make the high frequency. Current generation. The high-frequency current is supplied to the induction heating coil 222. The induction heating coil 22 generates a high-frequency magnetic field by the supplied high-frequency current. The eddy current is generated in the conductor 23 1 by the high-frequency magnetic field, and the conductor 23 1 generates heat. By the above operation, the control unit 410 can perform a rapid heating mode in which induction heating is performed so that the temperature of the seating surface of the toilet seat 200 continuously rises. For example, if the entrance detecting sensor 402 detects the entrance of the user, the control unit 410 can control the energization of the induction heating coil 222 to rapidly heat the toilet seat 200. Therefore, when the user sits on the toilet seat 200, it can become a warm temperature that does not feel cold. Next, when the user sits on the toilet seat 200 after sitting on the toilet seat 200, the control unit 410 outputs an instruction to keep warm and heat, and controls the ON/OFF of the first opening and closing element 551. The temperature of the seating surface of the toilet seat 200 is maintained at a predetermined temperature. At this time, when the oscillation control unit 257 controls only the ON/OFF of the first opening and closing element 551, an excessive opening/closing loss may occur in the first opening and closing element 515. Further, the first opening/closing element 51 is broken due to the opening and closing loss. Next, the problem that occurs when the seating surface of the toilet seat 200 is kept warm by induction heating and the operation of the heated toilet seat apparatus 100 of the present embodiment will be described with reference to the drawings. Fig. 5 is a timing chart for explaining the rapid heating mode and the heat retention heating mode of the heated toilet seat apparatus of the comparative example. Fig. 6 is a timing chart for explaining the rapid heating mode and the heat retention heating mode of the heated toilet seat apparatus of the embodiment. Further, Fig. 7 is a timing chart for explaining a minute heating mode of the heated toilet seat apparatus of the embodiment. As shown in Fig. 5(a), when the oscillation control unit 257 controls the first opening and closing element 551 to be in an ON state, the coil current IL flowing through the induction heating coil 222 increases (time point 11 0 1). ). Thereby, the magnetic energy is retained in the induction heating coil 222. Then, when the first opening/closing element 551 is controlled to be in an OFF state, the oscillation control unit 257 moves the magnetic energy remaining in the induction heating coil 222 as electrostatic energy toward the resonance capacitor 54 1 (time point t02). Therefore, the resonance voltage vCE will increase. Further, the resonance voltage VCE is a voltage applied to both ends of the first opening and closing element 551. Then, when the coil current IL becomes zero and flows in the opposite direction, the resonance voltage V c e starts to decrease (time point 11 〇 3 ). That is, the resonant capacitor 541 starts to discharge. Further, the 'resonance voltage vCE' is to be vibrated based on the input voltage of the resonance circuit 540 (refer to the broken line shown in FIG. 5(a)), but because it is built in, for example, the freewheeling of the opening and closing element 551. The diode 5 5 2 and the like are held 'become almost zero (time point u 〇 4). Further, -21 - 201244681 In the above operation, since the eddy current is generated in the conductor 231, the conductor 23 1 is heated, and the resonance energy is gradually attenuated. When the coil current U starts to increase again, the oscillation control unit 257 controls the first opening and closing element 551 to be in an ON state (time point tl 05). Thereby, the energy is again retained in the induction heating coil 222. In this manner, the LCR generated by the induction heating coil (L) 222, the resonance capacitor (C) 541, and the conductor (R) 231 resonate to cause the conductor 231 to generate heat. Therefore, in order to suppress the induction heating output when the toilet seat 200 is kept warm, there is a need to suppress the energy of the resonance operation. The energy of the resonance operation is determined by the vibration amplitude (current amplitude) and the frequency. Therefore, the control unit 410 performs the opening and closing control for reducing the period by reducing the vibration amplitude or decreasing the frequency to the first opening and closing element 515, thereby suppressing the induction heating output. However, considering that, for example, when the entrance detecting sensor 402 detects the entrance of the user and the control unit 410 controls the energization of the induction heating coil 222 to rapidly heat the toilet seat 200, the induction heating output in the rapid heating mode is For example, it is preferably about 1 watt or more. On the other hand, it is considered that the temperature of the sitting surface is kept at a predetermined temperature in which the user does not feel cold when sitting on the toilet seat 200, and the induction heating output in the heat retention heating mode is, for example, about 50 watts. That is, there is a larger difference between the induction heating output between the rapid heating mode and the heat retention heating mode, and the resonance frequency determined by the combination of the induction heating coil 222 and the resonance capacitor 541 is present during the induction heating. Generally, the opening and closing control of the first opening and closing element 55 1 is performed by the frequency in the vicinity of the resonance frequency. Therefore, in order to adjust the induction heating output, the opening and closing control of the first opening and closing element 5 5 1 is performed at an arbitrary frequency, and the resonance operation is repeated. Therefore, if the difference between the above-mentioned large induction heating outputs is controlled by the frequency adjustment, it is possible to pass the resonance operation. More specifically, in the heat retention heating mode, in order to suppress the induction heating output and lower the frequency than the rapid heating mode, it is necessary to turn on the ON state of the first opening and closing element 551 (hereinafter referred to as "conduction" for convenience of explanation. (ON) Time") is longer. When the ON time of the first opening and closing element 551 becomes long, the coil current U changes greatly. This causes the vibration amplitude to increase. Therefore, the effect of suppressing the induction heating output cannot be obtained. That is, if the frequency is lowered only, the induction heating output cannot be lowered, and it is necessary to adjust the induction heating coil 222 and the resonance capacitor 54 1 to a lower frequency. On the other hand, in order to suppress the induction heating output in the heat retention heating mode, it is considered that the vibration amplitude is smaller than the rapid heating mode. As shown in Fig. 5(b) and Fig. 5(〇), when the ON time of the first opening and closing element 55 1 is shorter than the rapid heating mode, the vibration amplitude can be made more in the heat retention mode than in the rapid heating mode. However, when the ON time of the first opening and closing element 551 is shorter than the rapid heating mode, as shown in FIG. 5(c), the opening and closing loss of the first opening and closing element 515 may become a problem. In the induction heating system, one of the reasons for the above-described resonance operation is that the first switching element 551 is turned on by the oscillation control unit 25 7 when the voltage of the first switching element 551 becomes 0 V (zero volt). In the (ON) state, the opening and closing loss is suppressed. The resonance amplitude in the resonance operation of -23-201244681 shown in Fig. 5(a) and Fig. 5(b) is a resonance operation as shown in Fig. 5(c). In the resonance operation shown in Figs. 5(a) and 5(b), the voltage of the first opening and closing element 515 is the time when the resonance voltage VCE becomes zero volts. Point (time point tl04~tl06, tl 14~tll6). Therefore, as in Figure 5(a) and In the resonance operation shown in FIG. 5(b), when the resonance voltage VCE is zero volt, the first opening/closing element 551 is turned on (the so-called "zero volt opening and closing operation") by the control unit 410. On the other hand, the resonance amplitude 'in the resonance operation shown in Fig. 5(c) is a resonance in the resonance operation as shown in Fig. 5 (a) and Fig. 5 (b). The input voltage of the resonance circuit 540 which is the reference for the vibration of the resonance voltage VCE is the resonance circuit 540 in the resonance operation as shown in Figs. 5(a) and 5(b). Since the input voltage is the same, the resonance voltage VCE does not become zero volt even if it is based on the input voltage of the resonance circuit 540. Therefore, the oscillation control unit 257 performs the low-induction induction heating operation, The resonance of the resonance energy is suppressed to continue the resonance operation, and when the resonance voltage VCE is not zero volts, it is necessary to turn the first opening and closing element 551 into an ON state. That is, in the resonance operation shown in FIG. 5(c), the control is performed. Department 4 1 0, is unable to carry out zero volts In this case, the opening and closing loss increases, and the first opening and closing element 515 may be broken or burned. In order to avoid the destruction of the opening and closing element 515, it is also considered that the induction heating operation is intermittent by the control unit 4 1 〇 The method of uniformly suppressing the induction heating output and keeping the temperature of the sitting surface of the toilet seat 200 at a predetermined temperature is in the range of -24,446,446. However, the user's skin feels the conduction (ON) of the induction heating operation and The control unit 410 of the present embodiment outputs an instruction to perform the step-down of the output instruction determination unit 25 1 as a result of the reverse (OFF). 5 23 is an opening and closing control of the second opening and closing element 521, and the rectified output of the rectifying unit 510 is sufficiently stepped down. That is, the control unit 410 controls the difference between the inductive heating output between the rapid heating mode and the heat retention heating mode using the step-down unit 520. When the high-frequency power supply circuit 500 shown in FIG. 3 is provided in the toilet seat 200, the step-down unit 520 can be input from the voltage of the rectification unit 510, that is, the voltage of the rectification unit 510. The power ratio of the ON time of the second opening and closing element 521 is determined. Further, in the step-down unit 520, the higher the input voltage of the step-down unit 520, the more the power ratio of the ON-ON time of the second switching element 521 is determined to be smaller. In this manner, the step-down control unit 523 determines the power ratio corresponding to the input voltage of the step-down unit 520, and can perform feedforward control that does not affect the output voltage of the step-down unit 520. Thereby, even when the high-frequency power supply circuit 500 is operated such that a large current flows, the input side of the step-down unit 520 can be blocked. For example, any abnormal operation increases the induction heating output, and the output voltage of the step-down unit 520, which is the input voltage of the inverter 550, is lowered, and the step-down unit 520 determines a larger power ratio, thereby avoiding the induction heating output. Further increase. Therefore, security can be improved. As described above, the induction heating output in the rapid heating mode is, for example, about 1000 watts. On the other hand, the induction heating output in the heat retention heating mode is -25 - 201244681, for example, about 50 watts. In other words, the control unit 401 controls the step-down unit 520 so that the power consumption amount in the heat-insulation heating mode is about 1/20 to 1/10 times the power consumption amount in the rapid heating mode, and the rectifying unit 510 is controlled. The rectified output is sufficiently depressed. Thus, the temperature of the toilet seat 200 in the heat retention heating mode can be stabilized, and the leakage magnetic field can be more reliably suppressed. In addition, the power consumption amount is detected by the power consumption amount detecting unit 430 (refer to FIG. 3 and FIG. 4). First, as shown in FIG. 6(a), the control unit 410 executes the first. In the case of the rapid heating mode, the second opening and closing element 52 1 is controlled to be continuously turned ON. Thus, in the first rapid heating mode, the rectified output of the rectifying unit 510 is supplied to the inverter 550 without being stepped down by the step-down unit 520. In other words, the rectified commercial power source 10 and the induction heating coil 222 are connected in series. The control unit 410 can rapidly heat the temperature of the seating surface of the toilet seat 200 continuously. The operation or state of the first opening and closing element 551, the coil current IL, and the resonance voltage VCE is the same as the operation or state of the first opening and closing element 551, the coil current IL, and the resonance voltage VCE in the fifth diagram (a). As shown in Fig. 6(b), when the second rapid heating mode is executed, the control unit 410 performs opening and closing control of the second opening and closing element 51. Thus, in the second rapid heating mode, the rectified output of the rectifying unit 510 is supplied to the inverter 550 in a step-down manner by the step-down unit 520. In the second rapid heating mode, the control unit 410 may rapidly heat the temperature of the seating surface of the toilet seat 200 continuously. Since the rectified output of the rectifying unit 510 is stepped down by the step-down unit 520 -26- 8 201244681 ', the line 圏 current IL is smaller than the line 圏 current U in the first rapid heating mode. In other words, the vibration amplitude of the coil current U in the second rapid heating mode is smaller than the vibration amplitude of the coil current IL in the first rapid heating mode. Therefore, the resonance amplitude of the resonance voltage VCE in the second rapid heating mode is smaller than the resonance amplitude of the resonance voltage VCE in the first rapid heating mode. Further, the resonance energy in the second rapid heating mode is smaller than the resonance energy in the first rapid heating mode. The control unit 401 does not need to change the resonance operation (the ON time and frequency of the first switching element), and the voltage of the rectifying unit 510 is stepped down by the step-down unit 520, so that the 2 The induction heating output in the rapid heating mode is suppressed more than the induction heating output in the first rapid heating mode. Therefore, the control unit 410 performs the temperature increase rate of the seating surface of the toilet seat 200 in the rapid heating mode by the pressure reducing unit 520, thereby suppressing an excessive rise in temperature. Since the rectified output of the rectifying unit 510 is stepped down in the step-down unit 520, the input voltage of the resonant circuit 540 which is the reference for the vibration of the resonant voltage VCE is higher than the input voltage of the resonant circuit 540 in the first rapid heating mode. low. Therefore, even if the resonance amplitude in the second rapid heating mode is smaller than the resonance amplitude in the first rapid heating mode, the resonance voltage V c e becomes zero volts (time point t214 to t216). Therefore, the control unit 401 can suppress the opening and closing loss by performing the second rapid heating mode zero volt opening and closing operation. As shown in Fig. 6(c), when the control unit 401 is in the heat-insulated heating mode, the opening and closing of the opening and closing device 5 2 1 of the -27-201244681 2 is performed in the same manner as in the case where the second rapid heating mode is executed. Control instructions. Further, the control unit 410 uses the step-down unit 520 to lower the rectified output of the rectifying unit 510 more than the rectified output in the first and second rapid heating modes. In other words, the rectified output of the rectifying unit 5 10 is supplied to the inverter 505 in a step-down manner in which the rectification output of the step-down unit 520 is sufficiently stepped down than that of the first and second rapid heating modes. The control unit 410 can keep the temperature of the seating surface of the toilet seat 200 at a predetermined temperature. Since the rectified output of the rectifying unit 510 is sufficiently stepped down by the step-down unit 520, the coil current U is smaller than the coil current I L in the first and second rapid heating modes. That is, the vibration amplitude of the coil current II in the heat preservation heating mode. This is smaller than the vibration amplitude of the coil current I L in the first and second rapid heating modes. Therefore, the resonance amplitude of the resonance voltage VCE in the heat retention heating mode is smaller than the resonance amplitude of the resonance voltage VCE in the first and second rapid heating modes, and the resonance energy in the heat retention heating mode is higher than that of the first and The resonance energy in the second rapid heating mode is smaller. The control unit 401 can change the rectification output of the rectifying unit 510 sufficiently by the step-down unit 520 without changing the resonance operation, so that the induction heating output in the heat retention heating mode can be made higher than that of the first and the third 2 The induction heating output in the rapid heating mode is more suppressed. Therefore, the control unit 4 10 0 can calculate the power consumption ratio. The electric power consumption in the first and second rapid heating modes is lower, and the temperature of the seating surface of the toilet seat 200 is kept at a predetermined temperature. Further, it is possible to suppress the temperature of the seating surface of the toilet seat 200 from rising sharply and suppress the occurrence of temperature unevenness. Therefore, it is possible to suppress the feeling of discomfort to the user sitting on the toilet seat 200. -28-201244681 The oscillation control unit 257 compares with the first and second rapid heating modes. ‘The control cycle in which the first opening and closing element 551 is turned ON/OFF is not required. The oscillation control unit 257 can determine the period of the operating condition suitable for the resonance operation by the resonance circuit 540 without being affected by the magnitude of the induction heating output indicated by the control unit 4 10 0. Since the step-down unit 520 is sufficiently stepped down, the input voltage of the resonance circuit 540 which is the reference for the vibration of the resonance voltage VCE is lower than the input voltage of the resonance circuit 540 in the first and second rapid heating modes. . Therefore, even if the resonance amplitude in the heat retention heating mode is smaller than the resonance amplitude in the first and second rapid heating modes, there is a time point (time point t224 to t226) at which the resonance voltage VCE becomes zero volts. Therefore, the control unit 410 can suppress the opening and closing loss by performing the zero-volt opening and closing operation in the heat retention heating mode. Further, as shown in Fig. 7, the control unit 4 1 〇 sufficiently reduces the rectified output of the rectifying unit 510 by the step-down unit 52 同样 in the same manner as the heat retention heating mode, and by first opening and closing the element 551 The ON time is shorter than the first and second rapid heating modes and the heat retention heating mode, and the minute heating mode can be implemented. Thereby, the aforementioned effects can be obtained in the heat retention heating mode, and further energy saving can be achieved. Further, since the rectified output of the rectifying unit 510 is sufficiently stepped down by the step-down unit 520, the input voltage of the resonant circuit 540 which is the reference for the vibration of the resonant voltage VCE is higher than the first and second rapid heating modes. The input voltage of the resonant circuit 5 40 is lower. Therefore, even if the ON time of the first opening/closing element 55 i is shorter than the ON time in the first and second rapid heating modes and the -29-201244681 heating mode, the resonance voltage VcE becomes The time point of zero volts (time point 12 3 4~12 3 6). Therefore, the control unit 410 can suppress the opening and closing loss by performing the zero-volt opening and closing operation in the heat retention heating mode. Fig. 8 is a graph for explaining a step-down operation and a leakage magnetic field of the heated toilet seat apparatus of the embodiment. The current supplied from the commercial power source 1 is the power supply voltage after the rectification unit 5 10 is rectified (after full-wave rectification), as shown in Fig. 8(a). As shown in Fig. 8(b), the step-down control unit 523 generates the same amplitude as the power supply voltage as shown in Fig. 8(a) by the triangular wave converting unit 5 25 (refer to FIG. 3). Triangle wave. Then, as shown in Fig. 8(c), the voltage of the generated triangular wave and the predetermined voltage are compared with each other by the comparator 526, and the power ratio of the ON time of the second switching element 521 of the step-down unit 520 is determined. In this case, as shown in Fig. 8(d), the output voltage of the step-down unit 520, that is, the input voltage of the resonance circuit 540 is limited. Thus, the coil in the heat retention heating mode is as described above in Fig. 6(c). The current II is smaller than the 槔圏 current IL in the first and second rapid heating modes. That is, the vibration amplitude of the coil current U in the heat retention heating mode is smaller than the vibration amplitude of the coil current U in the first and second rapid heating modes. Therefore, the leakage magnetic field generated from the induction heating coil 222 is suppressed, and the influence on the user sitting on the toilet seat 200 can be suppressed. Further, the induction heating operation is intermittently performed in the heat retention heating mode in which the average output is decreased. In the method, since the vibration amplitude of the line current -30-201244681 coil current IL at the moment of the induction heating operation becomes large, the user who sits on the toilet seat 200 is worried about the influence. Next, a specific example of the operation of the heated toilet seat apparatus 100 of the present embodiment will be described with reference to the drawings. Fig. 9 is a timing chart showing a specific example of the operation of the heated toilet seat apparatus of the present embodiment. First, before the entrance detecting sensor 402 detects the entrance of the user, the temperature of the sitting surface of the toilet seat 200 is room temperature, and is not kept in a predetermined temperature that the user does not feel cold (time point t3 01) before). When the entrance detecting sensor 402 detects the entrance of the user, the control unit 410 controls the second opening/closing element 521 to be continuously turned ON, and controls the opening and closing of the first opening and closing element 55 1 . The instruction output is started and the rapid heating mode is executed (time point t301). Thereby, the seating surface of the toilet seat 200 is rapidly heated with a continuous temperature rise. When the temperature of the seating surface of the toilet seat 200 is at a suitable temperature (target temperature, set temperature, etc.), the control unit 410 performs the opening and closing control of the second opening and closing element 52 1 to rectify the rectifying unit 5 10 . The output is subjected to the heat retention heating mode (time point t3 02) more than the rectified output in the rapid heating mode. Thereby, the seating surface of the toilet seat 200 can be kept warm at a suitable temperature, i.e., a predetermined temperature, in which the user does not feel cold. In other words, the amount of heating for warming the seating surface of the toilet seat 200 and the amount of heat released from the toilet seat 20 0 are stable at a temperature of thermal equilibrium. Then, when the user manually opens the toilet lid 300, or is opened by an operation such as a remote controller (not shown), the toilet lid is opened and closed to detect -31 - 201244681 sensor 406, which is a toilet lid detected. 3 00 is started to open (time point t3 03), and an intermediate state between the closed state and the open state of the toilet cover 300 is detected (time point t3 03 to t304). Next, the toilet lid opening and closing detection sensor 4〇6 is a state in which the toilet lid 300 is detected to be opened (time point t304). In addition, when the entrance detecting sensor 402 detects the entrance of the user, the control unit 41 may perform control for automatically opening the toilet lid 3 by a toilet lid opening/closing driving unit or the like (not shown). . Next, when the user sits on the toilet seat 200, the sensor 404 is detected, and it is detected that the user has sat in the toilet seat 200 (time point t3 05). And, when the user is seated from the toilet seat 200, the sitting detector 404' detects that the user is not sitting in the toilet seat 200 (time point t3 06). Then, when the user closes the toilet lid 300 by manual operation or is closed by a remote control or the like, the toilet lid opens and closes the sensor 406, and the toilet lid 300 is detected to be closed. (Time point t307), the state between the open state of the toilet lid 300 and the closed state is detected (time point t3 07 to t3 08). Next, the toilet lid opening and closing detection sensor 4 06 ' is a state in which the toilet lid 300 is closed (time point t3 0 8). In addition, when the room detection sensor 402 detects the user's exit room, the control unit 4 1 〇 'is controlled by automatically opening the lid 3 00 by means of a toilet lid opening/closing drive unit (not shown). (after time t3 09). When the room detection sensor 402 detects the user's exit room, the control unit 410 stops the opening and closing control of the second opening and closing element 521, and outputs the stop instruction output of the opening and closing control of the first opening and closing element 5 51. The heating mode is stopped (time point t309). That is, the control unit 410 stops the heating of the toilet seat -32 - 201244681 200. Therefore, the temperature of the sitting surface of the toilet seat 200 gradually decreases (after time t3 09). According to this specific example, when the entrance detecting sensor 402 detects the entrance of the user, the control unit 410 performs the rapid heating mode, and the seating surface of the toilet seat 200 can be rapidly heated by induction heating. Therefore, when the toilet seat 200 is not used by the user, it is not necessary to heat the toilet seat 200, and power consumption during standby can be suppressed, and energy saving can be achieved. Further, when the temperature of the seating surface of the toilet seat 200 is at a suitable temperature, the control unit 410 executes the heat insulating mode so that the temperature of the seat surface of the toilet seat 200 can be kept at a predetermined temperature by induction heating. Therefore, it is not necessary to set the heating means for rapid heating and the heating means for heat preservation and heating to different systems, and it is possible to realize rapid heating and heat preservation by a simpler structure. Fig. 10 is a timing chart showing another specific example of the operation of the heated toilet seat apparatus of the embodiment. The operation before the entrance detecting sensor 402 detects the user's entry into the room is the same as the operation before the time point t3 0 1 in the above-described specific example of Fig. 9 (before the time point t31 1). When the entrance detecting sensor 402 detects the entrance of the user, the control unit 410 controls the second opening/closing element 521 to be continuously turned ON, and controls the opening and closing of the first opening and closing element 55 1 . The instruction output is started and the first rapid heating mode is executed (time point t3 1 1). Thereby, the seating surface of the toilet seat 200 is rapidly heated with a continuous temperature rise. When the temperature of the seating surface of the toilet seat 200 is raised to a temperature lower than the appropriate temperature by, for example, 3 ° C, the control unit 4 10 performs the opening and closing control of the second opening and closing element -33 - 201244681 piece 5 2 1 The rectification output of the rectifying unit 5 10 0 is stepped down to execute the second rapid heating mode (time point 13 1 2). Thereby, the induction heating output in the second rapid heating mode is suppressed more than the induction heating output in the first rapid heating mode. Therefore, as shown in Fig. 10, the rate of rise (rise speed) of the temperature of the seating surface of the toilet seat 200 in the second rapid heating mode is higher than the seating surface of the toilet seat 2000 in the first rapid heating mode. The rate of temperature rise is lower (time point t3 12~t3 13). In the second rapid heating mode, the control unit 410 may rapidly heat the temperature of the seating surface of the toilet seat 200 continuously. Further, the timing at which the control unit 410 switches from the first rapid heating mode to the second rapid heating mode is not limited to the case where the temperature of the seating surface of the toilet seat 200 is increased to a temperature lower by 3 °C than the appropriate temperature. The temperature difference (3 ° C in this specific example) at the time of switching of the heating mode can be appropriately changed. When the temperature of the seating surface of the toilet seat 200 is at a suitable temperature, the control unit 4 10 0 ' is a condition for changing the opening and closing control of the second opening and closing element 5 2 1 'specifically, the conduction of the second opening and closing element 521 is reduced ( The ON-time power ratio performs the heat retention heating mode (time point 13 1 3 ) by lowering the rectified output of the rectifying unit 510 more than the rectified output in the first and second rapid heating modes. Thereby, the seating surface of the toilet seat 200 can be kept warm at a suitable temperature, i.e., a predetermined temperature, in which the user does not feel cold. Next, the operation ' at the time point t314 to t32〇 is the same as the operation at the time point t3〇3 to t309 in the above-described specific example of Fig. 9. According to this specific example, the "rapid heating mode" includes a first rapid heating mode and a second rapid heating mode. In the first rapid heating mode -34-201244681, the control unit 4 1 0 controls the second opening/closing element 5 2 1 to be continuously turned ON, and supplies the rectified output of the rectifying unit 510 to the inverter in a step-down manner. 550. On the other hand, in the second rapid heating mode, the control unit 410 performs opening/closing control of the second opening/closing element 52 1 and supplies the rectified output of the rectifying unit 5 10 to the inverter 550 in a step-down manner. Thereby, the control unit 410 is controlled by the pressure reducing unit 520 to control the temperature increase rate of the seat surface of the toilet seat 200 in the rapid heating mode, thereby suppressing excessive temperature rise. In the following specific example, the rapid heating mode is executed when the predetermined condition is satisfied, and the heat retention heating mode is executed when the predetermined condition is not satisfied. That is, the execution period of the rapid heating mode is restricted when the predetermined condition is established. Fig. 1 is a timing chart showing another specific example of the operation of the heated toilet seat apparatus of the present embodiment. In the present embodiment, the user does not perform the rapid heating mode when sitting on the toilet seat 200, and the user keeps the heating mode in the toilet seat 200. That is, the execution of the rapid heating mode is suppressed while the user is sitting. The operation of this specific example is a case where the heated toilet seat device 100 does not have the toilet lid 300, a case where the toilet lid opening/closing detecting sensor 406 is not provided, and a toilet lid opening and closing detecting sensor. One of the effective actions such as the case where the 406 is faulty and the state in which the toilet lid 300 is opened is recognized as the closed state. The operation before the entrance detecting sensor 402 detects the user's entry into the room is the same as the operation before the time point t3 0 1 in the above-described specific example of Fig. 9 (before the time point t321). Next, when the entrance detecting sensor 402 detects the entrance of the user, the control unit 41 0 controls the second opening and closing element -35 - 201244681 521 to be continuously turned on (〇. In the state of N), the start instruction of the opening and closing control of the first opening and closing element 55 1 is output and the rapid heating mode is executed (time point t321). Thereby, the seating surface of the toilet seat 200 is rapidly heated with a continuous temperature rise. Next, before the temperature of the sitting surface of the toilet seat 200 becomes warm, the sitting detection sensor 404 detects that the user sits in the toilet seat 200, and the control unit 410 performs the second opening and closing element 5 2 1 The opening and closing control performs the heat retention heating mode (time point t3 22) by lowering the rectified output of the rectifying unit 510 more than the rectified output in the rapid heating mode. Further, the control unit 410 performs the heat retention heating mode to make the temperature of the seating surface of the toilet seat 200 suitable (time point t3 2 3). Next, the operation at the time point t3 24 to t3 2 5 is performed in addition to the operation of the toilet lid opening and closing detection sensor 406, and is the operation at the time point t3 06 to t3 09 in the specific example of the ninth diagram. same. According to this specific example, even if the temperature of the sitting surface of the toilet seat 200 becomes warm, the sitting detection sensor 404 detects that the user sits in the toilet seat 200, and the control unit 4 10 stops the rapid heating. Insulation heating mode is implemented in the mode. That is, when the user sits on the toilet seat 200, the control unit 410 suppresses the execution of the rapid heating mode. Thereby, the safety for the user sitting on the toilet seat 200 can be further enhanced. Fig. 12 is a flow chart showing another specific example of the operation of the heated toilet seat apparatus of the embodiment. The operation of this specific example is an example of -36-201244681 which combines the operation of the above-described specific example of Fig. 10 and the operation of the above-described specific example of the second embodiment. The operation of this specific example is one of the effective operations such as the case where the user wants to sit in the toilet seat 2 during the execution of the rapid heating mode. First, the 'control unit 4 1 〇 ' determines whether the temperature of the toilet seat 2 〇 is lower than the upper limit (step S 1 0 1). The temperature of the toilet seat 2 is detected by, for example, a thermistor 2 5 5 (refer to Fig. 3). When the temperature of the toilet seat 2 is lower than the upper limit (step S 1 〇1 : γ ES ), the control unit 401 determines whether the user enters based on the detection signal of the entrance detecting sensor 402. Toilet (step S103). On the other hand, when the temperature of the toilet seat 20 is not lower than the upper limit (step S101: NO (high temperature state)), the control unit 410 controls the second opening and closing element to be in an off state (step). S123), the stop instruction of the opening and closing operation of the first opening and closing element 515 is output to stop the induction heating (step S1 2 5). When the user enters the toilet (step S103: YES), the control unit 410 determines whether or not the temperature of the toilet seat 200 is appropriate (step si 〇 5). On the other hand, when the user does not enter the toilet (step S1〇3: NO), the control unit 410' performs the aforementioned operation in steps S123 and S125, and when the temperature of the toilet seat 200 is lower than the appropriate temperature. (Step S105: lower than the appropriate temperature), the control unit 401 determines whether the user is sitting in the toilet seat 200 based on the detection signal of the sitting detection sensor 404 (step S107). When the user does not sit in the toilet seat 200 (step S107: NO), the control unit 4 10 determines the difference between the temperature and the appropriate temperature of the toilet seat 200 (step S1 09). When the temperature of the toilet seat 200 is lower than the temperature of the appropriate temperature minus 3 ° C (step S1 09: toilet seat) <At a temperature of -3 °C, the control unit 4 1 〇 is a state in which the -37-201244681 second opening/closing element 521 is controlled to be continuously turned ON (step S13). Then, the control unit 401 sets a time limit for setting the first rapid heating mode (step S1 17), and activates the start instruction of the opening and closing operation of the first opening and closing element 551 to activate the induction heating (first rapid heating mode) (step S121). On the other hand, the temperature of the toilet seat 200 is lower than the moderate temperature, that is, when the temperature exceeds the temperature above the temperature of 3 ° C (step S 1 09 : suitable temperature > toilet seat 2 is suitable for temperature - 3 ° C ), the control unit 401 performs the opening and closing control of the second opening and closing element 5 2 1 , and the rectified output of the rectifying unit 5 10 is stepped down (step S15 15). Next, the control unit 410 sets the heating time of the second rapid heating mode in accordance with the temperature and the heating mode of the toilet seat 200 (step S1 19), and outputs the start instruction of the opening and closing operation of the first opening and closing element 515. The induction heating (second rapid heating mode) is actuated (step S121). When the temperature of the toilet seat 200 is moderate (step S105: suitable temperature), or when the user sits in the toilet seat 200 (step S107: YES), the control unit 401 performs the second opening and closing element 52. The opening and closing control of 1 causes the rectified output of the rectifying unit 510 to be stepped down more than the rectified output in the first and second rapid heating modes (step S111). Then, the control unit 410 activates the induction start (opening/closing heating mode) of the opening and closing operation of the first opening and closing element 551 (step S121). When the temperature of the toilet seat 200 is equal to or higher than the appropriate temperature (step s 1 0 5 : moderate temperature or higher (tip height)), the control unit 410 performs the above-described operations in steps S123 and S125. According to the specific example, the control unit 410 can control the temperature of the seating surface of the toilet seat 200 in the rapid heating mode by the 201244681 liter speed in the rapid heating mode to suppress excessive temperature rise, and can further improve the toilet seat. The safety of the user of 200. Fig. 13 is a timing chart showing another specific example of the heated toilet seat of the embodiment. Fig. 14 is a flow chart showing the operation of the heated toilet of this specific example. In this embodiment, the rapid heating mode is opened and closed by the lid when only the toilet lid opening and closing detects that the sensor toilet lid 300 is closed. When the toilet lid 300 is not detected, the toilet lid 300 is closed. The heat preservation heating mode is implemented. That is, the rapid heating mode is not performed except for the state of the toilet lid 300. This specific example is one of the effective actions when the toilet lid 300 is hit or the like in the execution of the rapid heating mode. The entrance detecting sensor 402 detects the user's entry before the room is the same as the time point t301 in the above-described specific example of Fig. 9 (before the time point t3 3 1). When the entrance detecting device detects that the user has entered the room, the control unit 412 controls the second 521 to be continuously turned on (ON), and outputs the start instruction of the first opening/closing element opening and closing control to execute the rapid operation. Heating mode is poor t33 1). Thereby, the seating surface of the toilet seat 200 is rapidly heated at a continuous temperature. Then, 'the temperature of the seating surface of the toilet seat 200 is appropriately opened and closed. The sensor 4 0 6 is opened when the toilet cover 300 is detected. The control unit 41 0 is opened to open the second opening and closing element 52 1 . The detection of the sitting device 406 is performed, the state in which the horse is closed is the closed operation, and the operation in the open state, the previous operation 4〇2 detects the closing of the component 55 1 (the time point rises) Before the temperature, the closing control of the toilet lid, -39-201244681, performs the heat retention heating mode (time point t3 32) by lowering the rectified output of the rectifying unit 510 more than the rectification output in the rapid heating mode (time point t3 32). By performing the heat retention heating mode, even after the toilet lid opening and closing detection sensor 406 detects that the toilet lid 300 is in the open state (time point t3 3 3), the temperature of the seating surface of the toilet seat 200 becomes moderate (time) Point 3 4). The operation of 'time point t335 to t339' is the same as the operation of time point 1300 to t3 0 9 in the above-described specific example of Fig. 9. Referring to Fig. 14 Flowchart, further explaining the specific example First, the operations of steps S201 to S207 are the same as the operations of steps S101 to S107 in the above-described specific example of Fig. 12. When the user does not sit in the toilet seat 200 (step S207: NO), control is performed. The portion 401 determines whether the toilet lid 300 is in the closed state based on the detection signal of the toilet lid opening and closing detection sensor 4〇6 (step S209). When the toilet lid 300 is in the closed state ( Step S209: YES (determination), the control unit 410 controls the second opening/closing element 521 to be continuously turned ON (step S21 3). Next, the control unit 410 is based on the temperature and heating of the toilet seat 200. In the mode, the heating time in the rapid heating mode is set (step S215), and the start instruction of the opening and closing operation of the first opening and closing element 551 is output to the induction heating (rapid heating mode) (step S221). That is, the control unit 4 1 0 is The rapid heating mode is performed only when the toilet lid 300 is in the closed state. On the other hand, the temperature of the toilet seat 200 is moderate (step S205: suitable temperature) 'or the case where the user sits in the toilet seat 200 ( Step-40- 201244681 S207 : YES), or when the toilet lid 300 is not closed (step S209: NO), the control unit 410 performs opening and closing control of the second opening and closing element 521 to make the rectification output ratio of the rectifying unit 5 10 The rectification output in the rapid heating mode is further stepped down (step S211). Next, the control unit 410 outputs the start instruction of the opening and closing operation of the first opening/closing element 551 to the induction heating (heat retention heating mode) (step S221). When the temperature of the toilet seat 200 is equal to or higher than the appropriate temperature (step S205: equal temperature or higher (slightly higher)), the control unit 410 performs the same steps S1 to S125 and S125 in the printing example of Fig. 2 Actions. According to this specific example, when the opening/closing detecting sensor 406 detects that the toilet lid is opened and the toilet lid is opened, the control unit 4 1 0 stops the rapid heating mode and performs the heat insulating mode. Therefore, the time during which the control unit 412 switches the heating mode from the rapid heating mode to the warm-up heating mode is a period in which the toilet lid 300 is secured from the start to the open state. Therefore, the safety of the user sitting on the toilet seat 200 can be improved. Fig. 15 is a timing chart showing another specific example of the operation of the heated toilet seat apparatus of the present embodiment. Fig. 16 is a flow chart showing the operation of the heated toilet seat apparatus of the specific example. In this specific example, only when the toilet lid opening and closing detecting sensor 406 does not detect that the toilet lid 300 is in the open state, the rapid heating mode is executed, and the toilet lid opening and closing detecting sensor 406 detects the toilet lid 300 as The insulated heating mode is implemented when the state is turned on. That is, in the execution of the rapid heating mode, -41 - 201244681, the toilet lid 300 is opened, and the rapid heating mode is executed until the toilet lid 300 is fully opened. The operation before the entrance detecting sensor 402 detects the user's entry into the room is the same as the operation before the time point t301 in the above-described specific example of Fig. 9 (before the time point t341). When the entrance detecting sensor 402 detects the entrance of the user, the control unit 410 controls the second opening and closing element 521 to be continuously turned ON, and starts the opening and closing control of the first opening and closing element 551. The output is instructed and the rapid heating mode is executed (time point t341). Thereby, the seating surface of the toilet seat 200 is rapidly heated with a continuous temperature rise. Next, before the temperature of the sitting surface of the toilet seat 200 becomes warm, the toilet lid opening and closing detecting sensor 406 continues to allow the rapid heating mode to continue even if the toilet lid 300 is detected to start to open (time point) 13 4 2). When the toilet lid opening/closing detecting sensor 406 detects that the toilet lid 3 is in the open state, the control unit 4 1 0 ' performs the opening and closing control of the second opening and closing element 5 2 1 and the rectifying unit 5 1 0 The rectified output is subjected to the insulation heating mode (time point 13 4 3) more depressurized than the rectified output in the rapid heating mode. The control unit 410 sets the temperature of the seating surface of the toilet seat 200 to a suitable temperature by performing the heat retention heating mode (time point t3 34). Next, the operation at time points t345 to t349 is the same as the operation at time points t3 〇 5 to t309 in the above-described specific example of Fig. 9. The operation of this specific example will be described with reference to the flowchart shown in Fig. 16. First, the operations of steps S301 to S307 are the same as the operations of steps S101 to S107 in the specific example of the above-mentioned 42-201244681 of Fig. 12. When the user is not sitting in the toilet seat 200 (step S3〇7: NO), the control unit 41 0 determines whether the toilet lid 300 is open based on the detection signal of the toilet lid opening and closing detection sensor 4〇6. In the state (step S3〇9). When the toilet lid 300 is not in the open state (step S309: NO), the control unit 4 1 状态 controls the second opening/closing element 51 1 to be continuously turned on (〇N) (step S313). Next, the control unit 410 sets the heating time in the rapid heating mode in accordance with the temperature of the toilet seat 200 and the heating mode (step S3 15). 'The start instruction of the opening and closing operation of the first opening and closing element 55 is outputted by induction heating ( The rapid heating mode is activated (step S321). That is, the control unit 410' executes the rapid heating mode if the toilet lid 300 is not in the fully open state. On the other hand, the temperature of the toilet seat 200 is moderate (step S3 05: suitable temperature), or the user sits in the toilet seat 200 (step S3 07: YES), or the toilet cover 300 is In the case of the open state (step S3 09: YES), the control unit 410 performs opening and closing control of the second opening and closing element 5 2 1 , and compares the rectification output of the rectifying unit 5 1 比 to the rapid heating mode. The rectified output is further stepped down (step S311). Next, the control unit 4 1 作 activates the induction start (opening/closing heating mode) of the opening and closing operation of the first opening and closing element (step S 3 2 1). When the temperature of the toilet seat 200 is equal to or higher than the appropriate temperature (step S3 05: moderate temperature or higher (slightly higher)), the control unit 410 performs the steps S 1 2 3, S in the specific example described above with reference to FIG. 1 2 5 The same action. According to this specific example, even if the horse lid -300 is opened until the toilet lid 300 is fully opened in the execution of the rapid heating mode, the control unit 410 performs the rapid heating mode. Therefore, between the opening of the toilet lid 300 and the fully open state, the control unit 410 is in the continuous rapid heating mode so that the temperature of the toilet seat 200 can be approached to a suitable temperature. Thereby, it is possible to more reliably suppress the user from feeling cold when sitting on the toilet seat 200. Fig. 17 is a timing chart showing another specific example of the operation of the heated toilet seat apparatus of the embodiment. In the present embodiment, when the temperature of the toilet seat 200, that is, the temperature at which the thermistor 25 5 is detected is higher than the predetermined 値 or becomes a predetermined 値, the control unit 410 controls the second opening and closing element to be turned off (OFF). In the state, the stop instruction of the opening and closing operation of the first opening and closing element 515 is output to stop the induction heating. The operation of this specific example is one of effective operations such as a case where the induction heating output is suddenly excessively large and a case where an unexpected operation occurs. The operation before the entrance detecting sensor 402 detects the user's entry into the room is the same as the operation before the time point t3 01 in the above-described specific example of Fig. 9 (before the time point t351). When the room entrance detecting sensor 402 detects the entrance of the user, the control unit 410 controls the second opening and closing element 521 to be continuously turned ON, and controls the opening and closing of the first opening and closing element 55 1 . Start the indication output and execute the rapid heating mode (time point t35 1). Thereby, the seating surface of the toilet seat 200 is rapidly heated with a continuous temperature rise. When the temperature of the toilet seat 200, that is, the temperature at which the thermistor 2W is detected, becomes the upper limit temperature (predetermined 値), the control unit 4 1 0 ' controls the second opening and closing element 521 to be in an OFF state. 1 The opening/closing element 55 1 - 44 - 201244681 The stop instruction output of the opening and closing operation stops the induction heating (time point t3 52). As a result, the temperature of the seating surface of the toilet seat 200 gradually decreases. Next, the toilet lid opening and closing detection sensor 460 is to detect that the toilet lid 300 starts to open (time point t3 5 3), and detects that the toilet lid 300 is in a closed state and an intermediate state between the opened state. (Time point t3 53~t3 54). When the temperature of the seating surface of the toilet seat 200 is at a suitable temperature, the control unit 4 1 〇 controls the opening and closing of the second opening and closing element 52 1 , and the rectifying output of the rectifying unit 5 1 0 is more than the rectifying output in the rapid heating mode. The heat preservation heating mode is implemented in a step-down manner (time point t3 5 5). Thereby, the seating surface of the toilet seat 200 can be kept warm at a suitable temperature, that is, a predetermined temperature at which the user does not feel cold. The operation at the time point t3 5 6 to t3 60 is the same as the operation at the time point 13 0 5 to 13 0 9 in the above-described specific example of Fig. 9. According to this specific example, the second opening and closing element has a function as a safety device. In other words, the control unit 410 is configured to control the second open/close element to be in an OFF state, thereby blocking the high frequency power supply circuit 500. Therefore, the security can be further improved. For example, even if the oscillation control unit 257 cannot stop the opening and closing operation of the first opening and closing element due to some circuit failure, the induction heating operation can be stopped to prevent the temperature of the toilet seat 200 from rising. Fig. 18 is a timing chart showing another specific example of the operation of the heated toilet seat apparatus of the embodiment. Fig. 19 is a flow chart showing the operation of the heated toilet seat apparatus of the specific example. The operation of this specific example is an example of an operation in which the operations of the above-described specific example of Fig. 10 and the specific examples of the above-described specific example of Fig. 3 are combined. In the present embodiment, in a state in which the toilet lid 300 is in a closed state and a state in which the state is open, that is, in the middle of the opening, the control unit 4 1 实行 performs a relatively weak rapid heating mode (second rapid speed) Heating mode). The operation of this specific example is one of the operations that are effective when the toilet lid 300 is opened during the execution of the rapid heating mode. The operation before the entrance detecting sensor 402 detects the user's entry into the room is the same as the operation before the time point t301 in the above-described specific example of Fig. 9 (before the time point t3 6 1). When the detection sensor 403 detects the entrance of the user, the control unit 406 switches the second opening/closing element 52 1 to be continuously turned ON, and controls the opening and closing of the first opening and closing element 5 5 1 . The start of the instruction is output and the first rapid heating mode is executed (time point t361). As a result, the seating surface of the toilet seat 200 is rapidly heated with a continuous temperature rise. Next, before the temperature of the seating surface of the toilet seat 200 becomes warm, the opening and closing detection sensor 406 detects the toilet lid 3 00. When the toilet lid is opened, the control unit 410 performs opening and closing control of the second opening and closing element 521, and performs a second rapid heating mode (time point 13 6 2 ) by stepping down the rectification output of the rectifying unit 510. Thus, the "induction heating output" in the "second rapid heating mode" is suppressed more than the induction heating output in the first rapid heating mode. Therefore, as shown in Fig. 18, the rate of increase in the temperature of the seating surface of the toilet seat 200 in the second rapid heating mode is higher than the rate of increase in the temperature of the seating surface of the toilet seat 200 in the first rapid heating mode. Low (time point t362~t363). -46 - 201244681 Next, when the toilet lid opening/closing detecting sensor 406 detects that the toilet lid 300 is fully open, the control unit 410 changes the opening and closing control of the second opening and closing element 5 21, and specifically reduces In the power ratio of the ON/OFF time of the second opening and closing element 52 1 , the rectification output of the rectifying unit 5 10 is further reduced in pressure compared to the rectification output in the first and second rapid heating modes (time point t3) 63). Thereby, the seating surface of the toilet seat 200 can be kept warm at a suitable temperature, i.e., a predetermined temperature, in which the user does not feel cold. And the control unit 410 is implemented by the heat retention heating mode, and when the sitting detection sensor 404 detects that the user is sitting on the toilet seat 200 (time point t364), the temperature of the seating surface of the toilet seat 200 can become warm. (Time point t3 65). Next, the operation at the time point t3 66 to t3 69 is the same as the operation at the time point t3 06 to t3 09 in the above-described specific example of Fig. 9. The operation of this specific example will be further described with reference to the flowchart shown in Fig. 19. First, the operations of steps S401 to S407 are the same as the operations of steps S101 to S107 in the above-described specific example of Fig. 12. When the user is not sitting in the toilet seat 200 (step S407: NO), the control unit 410 determines whether the toilet lid 300 is open according to the detection signal of the toilet lid opening and closing detection sensor 406 (step S409). When the toilet lid 300 is not in the open state (step S40 9 : NO), the control unit 4 1 0 'is judged whether the toilet lid 300 is in the closed state according to the detection signal of the toilet lid opening and closing detection sensor 406 (step S410). When the toilet lid 300 is in the closed state (step S410: YES), the control unit 4 1 0 controls the second opening and closing element 5 2 1 to be continuously turned on -47 - 201244681 (ON). Status (step su3). Next, the control unit 410 sets the start time of the opening and closing operation of the first opening and closing element 515 to the induction heating (the first rapid heating mode) by setting the limit time of the first rapid heating mode (step S4 17). Step S421). On the other hand, when the toilet lid 300 is not in the closed state (step S410: NO), the control unit 410 performs the opening/closing control of the second opening and closing element 521 to lower the rectification output of the rectifying unit 510 (step S415). Next, the control unit 410 sets the heating time of the second rapid heating mode in accordance with the temperature and the heating mode of the toilet seat 200 (step S4 and 9), and outputs the start instruction of the opening and closing operation of the first opening and closing element 515 to the induction heating. (Second rapid heating mode) is actuated (step S 4 2 1). On the other hand, the temperature of the toilet seat 200 is moderate (step S405: suitable temperature), or the user sits in the toilet seat 200 (step S407: YES), or the toilet lid 300 is open. In the case of the state (step S4 09: YES), the control unit 410 performs opening and closing control of the second opening and closing element 5 2 1 , and compares the rectification output of the rectifying unit 5 1 0 to the first and second rapids. The rectified output in the heating mode is further stepped down (step S4 11). Then, the control unit 401 outputs the start instruction of the opening and closing operation of the first opening/closing element 515 to the induction heating (heating heating mode) (step S 1 2 1). When the temperature of the toilet seat 200 is equal to or higher than the appropriate temperature (step S405: at a moderate temperature or higher (slightly higher)), the control unit 410 performs the same operations as steps S123 and S125 in the above-described specific example of Fig. 12. According to this specific example, when the toilet lid 300 is opened during the execution of the rapid heating mode, the control unit 4 1 0 performs induction heating until the toilet lid 300 is completely opened by 48-201244681. The second rapid heating mode in which the output is suppressed more than the i-th rapid heating mode. Thereby, safety can be ensured, and it is possible to more reliably suppress the user from feeling cold when sitting on the toilet seat 200. The above has described embodiments of the invention.
