Abstract
提供當自動調節加熱機構之調理容器加熱量時能以簡單之控制而將從調理容器檢測到之溫度之變動幅度抑制在小幅度之加熱調理器。 Provides a heating conditioner that can suppress the temperature fluctuation range detected from the conditioning container to a small range with simple control when automatically adjusting the heating amount of the conditioning container of the heating mechanism.
對調理容器進行加熱之加熱機構可依照複數個階段之加熱量級別之各加熱量級別來調節加熱量。自動改變加熱量之加熱控制機構是基於目標溫度而設定與各加熱量級別對應之溫度範圍,當檢測溫度超過與現在之加熱量級別對應之溫度範圍之上限值時令加熱量級別變小,當檢測溫度低於與現在之加熱量級別對應之溫度範圍之下限值時令加熱量級別變大。 The heating mechanism for heating the conditioning container can adjust the heating capacity according to the heating capacity levels of multiple stages. The heating control mechanism that automatically changes the heating capacity sets the temperature range corresponding to each heating capacity level based on the target temperature. When the detected temperature exceeds the upper limit of the temperature range corresponding to the current heating capacity level, the heating capacity level becomes smaller. When the detected temperature is lower than the lower limit of the temperature range corresponding to the current heating capacity level, the heating capacity level becomes larger.
Description
本發明是涉及具有因應調理容器之溫度而自動地調節加熱機構之調理容器加熱量之機能的加熱調理器。 The present invention relates to a heating conditioner having a function of automatically adjusting the heating amount of a conditioning container of a heating mechanism in response to the temperature of the conditioning container.
關於這類之加熱調理器,舉例來說是具有爐燃燒器來作為加熱機構之瓦斯爐、具有感應加熱(IH)部來作為加熱機構之電磁調理器、或是具有鎳鉻線加熱器來作為加熱機構之電爐等。 Regarding this type of heating conditioner, for example, a gas stove with a furnace burner as a heating mechanism, an electromagnetic conditioner with an induction heating (IH) part as a heating mechanism, or a nickel-chromium wire heater as Electric furnace of heating mechanism, etc.
而且,舉例來說,已知有一種瓦斯爐,具有對藉由爐燃燒器(加熱機構)而加熱之鍋等之調理容器之底部之溫度進行檢測之鍋底溫度感測器(溫度檢測機構),因應鍋底溫度感測器之檢測溫度而將爐燃燒器之火力(加熱量)以弱火與強火這樣之2段式來切換調節,欲藉此將調理容器之加熱溫度維持在預定之溫度範圍(例如,參考專利文獻1)。 Moreover, for example, there is known a gas stove having a pot bottom temperature sensor (temperature detection mechanism) that detects the temperature of the bottom of a conditioning container such as a pot heated by a furnace burner (heating mechanism), In response to the detection temperature of the pot bottom temperature sensor, the fire power (heating capacity) of the furnace burner is switched and adjusted in a two-stage type of low fire and strong fire, so as to maintain the heating temperature of the conditioning container within a predetermined temperature range (for example, , Refer to Patent Document 1).
然而,即便將加熱量以大小2階段式來切換調節,亦難以令內部收納有被加熱物之調理容器之溫度(鍋底溫度感測器之檢測溫度)維持在預定之溫度範圍,有著相對於目標溫度之調理容器之溫度變動幅度大之問題。 However, even if the heating volume is adjusted in a two-stage manner, it is difficult to maintain the temperature of the conditioning container (the detection temperature of the pot bottom temperature sensor) that contains the object to be heated in a predetermined temperature range, which is relative to the target. The problem of large temperature fluctuations in the temperature conditioning container.
於是,在加熱機構,可依照將從最小加熱 量至最大加熱量為止之加熱量範圍分割成複數個階段之各加熱量級別來調節加熱量。然後,可想到的是,在控制加熱機構時,當檢測溫度上昇的情況下,因應檢測溫度與目標溫度之溫度差之減少而令加熱量級別變小複數個階段,當檢測溫度下降的情況下,因應檢測溫度與目標溫度之溫度差之增加而令加熱量級別變大複數個階段。 Therefore, in the heating mechanism, it can be heated from the minimum The heating capacity range up to the maximum heating capacity is divided into multiple heating capacity levels to adjust the heating capacity. Then, it is conceivable that when the detection temperature rises when the heating mechanism is controlled, the heating level is reduced in multiple stages in response to the decrease in the temperature difference between the detection temperature and the target temperature. When the detection temperature drops , In response to the increase in the temperature difference between the detected temperature and the target temperature, the heating level becomes larger in multiple stages.
根據此,當調理容器之溫度上昇而檢測溫度接近目標溫度時,隨著檢測溫度與目標溫度之差變小而令加熱量級別變小複數個階段,可將所謂之過衝(overshoot)抑制在最小限度,當調理容器之溫度降低而檢測溫度遠離目標溫度時,隨著檢測溫度與目標溫度之差變大而令加熱量級別變大複數個階段,可將所謂之下衝抑制在最小限度。 According to this, when the temperature of the conditioning container rises and the detected temperature approaches the target temperature, as the difference between the detected temperature and the target temperature becomes smaller, the heating level becomes smaller in multiple stages, so that the so-called overshoot can be suppressed at At a minimum, when the temperature of the conditioning container decreases and the detected temperature is far away from the target temperature, as the difference between the detected temperature and the target temperature increases, the heating level becomes larger in multiple stages, so that the so-called undershoot can be suppressed to a minimum.

發明概要 Summary of the invention
然而,要以上述之方法來抑制所謂之過衝與下衝的情況下,必須判斷調理容器之溫度是在上昇或下降,其控制會複雜。 However, in order to suppress the so-called overshoot and undershoot by the above-mentioned method, it is necessary to determine whether the temperature of the conditioning container is rising or falling, and its control will be complicated.
鑑於上述事情,本發明之目的是提供當自動調節加熱機構之調理容器加熱量時能以簡單之控制而將 從調理容器檢測到之溫度之變動幅度抑制在小幅度之加熱調理器。 In view of the above matters, the purpose of the present invention is to provide a simple control when the heating amount of the conditioning container of the heating mechanism is automatically adjusted. The temperature fluctuation range detected from the conditioning container is suppressed to a small range of heating conditioners.
為了達成所述目的,本發明是在加熱調理器具有:加熱機構,對裝有被調理物之調理容器進行加熱;溫度檢測機構,檢測前述調理容器之溫度;加熱控制機構,增減前述加熱機構之加熱量,以令該溫度檢測機構之檢測溫度成為事先設定之目標溫度;其特徵在於:前述加熱機構可依照將從最小加熱量至最大加熱量為止之加熱量範圍分割成複數個階段之各加熱量級別來調節加熱量;前述加熱控制機構是基於前述目標溫度而設定與各加熱量級別對應之溫度範圍,當前述溫度檢測機構之檢測溫度超過與現在之加熱量級別對應之溫度範圍之上限值時令加熱量級別變小,當前述溫度檢測機構之檢測溫度低於與現在之加熱量級別對應之溫度範圍之下限值時令加熱量級別變大。 In order to achieve the above-mentioned object, the present invention is provided with a heating conditioner: a heating mechanism to heat the conditioning container containing the object to be conditioned; a temperature detection mechanism to detect the temperature of the aforementioned conditioning container; a heating control mechanism to increase or decrease the aforementioned heating mechanism The heating capacity of the temperature detection mechanism is to make the detection temperature of the temperature detection mechanism become the preset target temperature; it is characterized in that the heating mechanism can be divided into a plurality of stages according to the heating capacity range from the minimum heating capacity to the maximum heating capacity. The heating volume level is used to adjust the heating volume; the aforementioned heating control mechanism sets the temperature range corresponding to each heating volume level based on the aforementioned target temperature, when the detection temperature of the aforementioned temperature detection mechanism exceeds the temperature range corresponding to the current heating volume level The limit value reduces the heating level, and when the temperature detected by the aforementioned temperature detection mechanism is lower than the lower limit of the temperature range corresponding to the current heating level, the heating level becomes larger.
當加熱機構開始對裝有被調理物之調理容器加熱,則加熱控制機構自動調節加熱機構之加熱量以令溫度檢測機構之檢測溫度成為目標溫度。在加熱機構開始加熱之初期階段,由於溫度檢測機構之檢測溫度比目標溫度還低,故加熱控制機構是對加熱機構進行令加熱量級別變大之控制。此期間,加熱控制機構因應檢測溫度之變化而算出檢測溫度與目標溫度之差。 When the heating mechanism starts to heat the conditioning container containing the conditioned object, the heating control mechanism automatically adjusts the heating amount of the heating mechanism so that the detected temperature of the temperature detection mechanism becomes the target temperature. In the initial stage when the heating mechanism starts to heat, since the detected temperature of the temperature detection mechanism is lower than the target temperature, the heating control mechanism controls the heating mechanism to increase the heating level. During this period, the heating control mechanism calculates the difference between the detected temperature and the target temperature in response to changes in the detected temperature.
然後,因為調理容器之溫度上昇令檢測溫 度接近目標溫度,檢測溫度與目標溫度之差會變小。伴隨於此,加熱控制機構是進行如下控制:依照各個預定之溫度差,因應檢測溫度與目標溫度之溫度差減少而令加熱量級別變小。 Then, because the temperature of the conditioning container rises, the detection temperature When the temperature is close to the target temperature, the difference between the detected temperature and the target temperature will become smaller. Along with this, the heating control mechanism performs the following control: according to each predetermined temperature difference, the heating amount level becomes smaller in response to the decrease in the temperature difference between the detected temperature and the target temperature.
另外,檢測溫度超過目標溫度之後,當檢測溫度從上昇轉為下降而檢測溫度低於目標溫度,則加熱控制機構是自動調節加熱量以抑制檢測溫度之過度降低。此期間,加熱控制機構因應檢測溫度之變化而算出檢測溫度與目標溫度之差。然後,因為調理容器之溫度降低令檢測溫度遠離目標溫度,檢測溫度與目標溫度之差會變大,故加熱控制機構是進行令加熱量級別變大之控制。 In addition, after the detected temperature exceeds the target temperature, when the detected temperature changes from rising to falling and the detected temperature is lower than the target temperature, the heating control mechanism automatically adjusts the amount of heating to prevent an excessive decrease in the detected temperature. During this period, the heating control mechanism calculates the difference between the detected temperature and the target temperature in response to changes in the detected temperature. Then, because the temperature of the conditioning container decreases and the detected temperature is far away from the target temperature, the difference between the detected temperature and the target temperature will become larger, so the heating control mechanism performs control to increase the heating level.
在本發明,藉由加熱控制機構,基於目標溫度而設定與各加熱量級別對應之溫度範圍。只要檢測溫度是位於與現在之加熱量級別對應之溫度範圍內,則加熱控制機構是維持現在之加熱量級別。 In the present invention, the heating control mechanism sets the temperature range corresponding to each heating level based on the target temperature. As long as the detected temperature is within the temperature range corresponding to the current heating level, the heating control mechanism maintains the current heating level.
另一方面,當檢測溫度超過與現在之加熱量級別對應之溫度範圍的情況下,令加熱量級別變小而抑制溫度上昇,當檢測溫度低於與現在之加熱量級別對應之溫度範圍的情況下,令加熱量級別變小而抑制溫度降低。 On the other hand, when the detected temperature exceeds the temperature range corresponding to the current heating level, the heating level is reduced to suppress the temperature rise. When the detected temperature is lower than the temperature range corresponding to the current heating level , The heating level is made smaller and the temperature drop is suppressed.
藉由如此地使用與各加熱量級別對應之溫度範圍而判斷加熱量級別之改變,不需要判斷檢測溫度是正在上昇或下降,控制變得簡單。 By using the temperature range corresponding to each heating level to determine the change of the heating level in this way, there is no need to determine whether the detected temperature is rising or falling, and the control becomes simple.
話說,若互相鄰接之加熱量級別間之境界之溫度相同,則可能因為溫度之輕微之變動之影響而在互 相鄰接之加熱量級別間細微地進行切換,亦即可能發生所謂之擺動現象。 In other words, if the temperature of the realm between adjacent heating levels is the same, it may be affected by the slight change in temperature. The adjacent heating levels are switched slightly, that is, the so-called swing phenomenon may occur.
於是,在本發明,前述各加熱量級別之前述溫度範圍宜在互相鄰接之加熱量級別間有一部分重疊。根據此,在互相鄰接之加熱量級別間之境界設有溫度範圍,從鄰接之其中一方之加熱量級別朝另一方之加熱量級別改變之溫度、以及從另一方之加熱量級別朝其中一方之加熱量級別改變之溫度會是不同之溫度。所以,舉例來說,由於剛變大之加熱量級別需要降低經過重疊部分之溫度才會改變成小的加熱量級別,故可防止擺動現象。 Therefore, in the present invention, it is preferable that the aforementioned temperature ranges of the aforementioned heating capacity levels partially overlap between the adjacent heating capacity levels. According to this, there is a temperature range between the adjacent heating levels, and the temperature changes from the heating level of one of the adjacent heating levels to the heating level of the other side, and the heating level from the other side to one of the heating levels. The temperature at which the heating level changes will be different. Therefore, for example, since the heating level that has just become larger needs to lower the temperature of the overlapping part before it can be changed to a small heating level, the swing phenomenon can be prevented.
另外,本發明之加熱調理器具有:操作旋鈕,可藉由使用者之操作而設定加熱量級別;複數個位置表示部,與該操作旋鈕之操作量對應而顯示各加熱量級別;發光元件,設在各位置表示部而可令複數種顏色之光選擇性地發光;發光元件控制機構,令顯示由使用者操作所設定之加熱量級別之位置表示部之發光元件發光,當前述加熱控制機構改變加熱量級別時,令顯示使用者設定之加熱量級別之位置表示部之發光元件維持發光之狀態,令顯示前述加熱控制機構改變之加熱量級別之位置表示部之發光元件,以與顯示使用者設定之加熱量級別之位置表示部之發光元件不同之顏色而發光。 In addition, the heating conditioner of the present invention has: an operating knob, which can be operated by the user to set the heating level; a plurality of position display parts, corresponding to the operating volume of the operating knob to display each heating level; light-emitting elements, It is set in each position display part to selectively emit light of multiple colors; the light-emitting element control mechanism makes the light-emitting element of the position display part that displays the heating level set by the user operation to emit light, when the heating control mechanism When the heating level is changed, the light-emitting element of the position indicator that displays the heating level set by the user is kept luminous, and the light-emitting element of the position indicator that displays the heating level changed by the heating control mechanism is used with the display. The light-emitting element of the position indicating part of the heating level set by the user emits light in different colors.
如上述,本發明之加熱調理器是藉由加熱控制機構而進行令調理容器之溫度成為目標溫度之加熱量自動調節。另一方面,本發明之加熱調理器亦可藉由使用 者進行之操作旋鈕之操作而設定加熱量級別。因此,當調理容器之加熱開始時,會發生使用者利用操作旋鈕而設定之加熱量級別被加熱控制機構改變之情形。於是,因為以與使用者手動設定之內容不同之加熱量而進行調理容器之加熱,故使用者會感覺到不對勁。 As mentioned above, the heating conditioner of the present invention uses the heating control mechanism to automatically adjust the heating amount to make the temperature of the conditioning container become the target temperature. On the other hand, the heating conditioner of the present invention can also be used by The operator performs the operation of the operating knob to set the heating level. Therefore, when the heating of the conditioning container starts, the heating level set by the user using the operating knob is changed by the heating control mechanism. Therefore, because the conditioning container is heated with a heating amount different from the content manually set by the user, the user feels something wrong.
對此,藉由前述發光元件控制機構,首先,令顯示使用者設定之加熱量級別之位置表示部之發光元件維持發光之狀態。之後,當加熱控制機構改變加熱量級別時,發光元件控制機構令顯示此時改變之加熱量級別之位置表示部之發光元件是以與顯示使用者設定之加熱量級別之位置表示部之發光元件不同之顏色來發光。藉此,使用者可視覺性地確認手動設定之加熱量級別與自動改變之加熱量級別,可減輕使用者感覺到之不對勁。 In this regard, by the aforementioned light-emitting element control mechanism, firstly, the light-emitting element of the position indicating portion displaying the heating level set by the user is maintained in a light-emitting state. After that, when the heating control mechanism changes the heating level, the light-emitting element control mechanism causes the light-emitting element of the position indicating section to display the heating level changed at this time with the light-emitting element of the position indicating section that displays the heating level set by the user Different colors to shine. In this way, the user can visually confirm the manually set heating level and the automatically changed heating level, which can alleviate the user's feeling of wrongness.

以下,若具體說明,則在本實施形態之瓦斯爐1,火力級別選擇部19是使用9階段(最小火力級別「1」~最大火力級別「9」)中之火力級別「1」「α」「β」
「γ」「9」而進行溫控。附帶一提,火力級別「α」「β」「γ」是適當設定之火力級別,火力級別之大小關係是「α」<「β」<「γ」。
In the following, if it is specifically explained, in the
另外,在本實施形態,火力控制部16之溫度範圍設定部18是以從目標溫度-5℃間隔來設定各火力級別之使用判斷時之閾值。亦即,舉例來說,當目標溫度是260℃時,如圖2所示,溫度範圍設定部18將與火力級別「9」對應之用於控制之溫度範圍(以下,稱作控制溫度範圍)設定在低於235℃,將與火力級別「γ」對應之控制溫度範圍設定在235℃~240℃,將與火力級別「β」對應之控制溫度範圍設定在240℃~245℃,將與火力級別「α」對應之控制溫度範圍設定在245℃~250℃,將與火力級別「1」對應之控制溫度範圍設定在250℃以上。
In addition, in the present embodiment, the temperature
再者,如圖2所示,本實施形態不只是依照各加熱量級別而設定對應之控制溫度範圍,還在使用之火力級別「1」「α」「β」「γ」「9」之鄰接之火力級別間設置溫度範圍重疊之部分,藉此,可防止因為細微之溫度變化之影響而細微地切換鄰接之火力級別,亦即可防止所謂之擺動現象。 Furthermore, as shown in Figure 2, the present embodiment not only sets the corresponding control temperature range according to each heating level, but also uses adjacent heat levels "1", "α", "β", "γ", and "9". Setting the overlap of the temperature range between the firepower levels can prevent the neighboring firepower levels from being slightly switched due to the influence of subtle temperature changes, which can also prevent the so-called swing phenomenon.
在此,說明溫控下之火力級別之選擇。首先,如圖3所示,使用者對操作旋鈕10進行操作而在爐燃燒器2點火,火力控制部16在步驟1檢測到此時之點火則往步驟2前進,溫度範圍設定部18基於目標溫度而設定閾值。此時,假設點火時之點火火力是火力級別「β」。另
外,在本實施形態是以260℃作為目標溫度,以從該目標溫度-5℃間隔而設定閾值。
Here, the choice of firepower level under temperature control is explained. First, as shown in FIG. 3, the user operates the
進一步前進至步驟3,溫度範圍設定部18是如前述般地設定與各火力級別「1」「α」「β」「γ」「9」分別對應之控制溫度範圍(參考圖2),在步驟4是藉由火力級別選擇部19而進行與鍋底溫度感測器7之檢測溫度對應之火力級別之選擇(改變)(此處理是後述)。然後,步驟5是令步驟4之處理反覆進行,直到檢測到熄火為止。
Going further to step 3, the temperature
針對步驟4之處理(火力級別之選擇處理)進行說明,如圖4所示,在步驟6,火力控制部16由鍋底溫度感測器7進行溫度檢測,步驟7以後,藉由火力級別選擇部19之運作而進行火力級別之選擇(改變)與該火力級別之爐燃燒器2之控制。
The processing of step 4 (selection processing of the firepower level) is described. As shown in FIG. 4, in step 6, the
說明概要,在步驟7~步驟10是判斷現在之火力級別,在步驟11~步驟18是對檢測溫度Tr、與各火力級別對應之控制溫度範圍進行比較,因應需要而改變火力級別,進行與步驟19~步驟26之各條件對應之處理。
Explain the outline.
舉例來說,當現在之火力級別是「γ」時,在步驟8朝步驟12前進,在步驟12判斷出鍋底溫度感測器7之檢測溫度Tr(在步驟6獲得之溫度)是240℃以上的情況下,在步驟20將火力級別改變成「β」。在步驟13判斷出檢測溫度Tr低於230℃的情況下,在步驟21將火力級別改變成「9」。雖然在此結束火力級別之選擇,但因為往圖3之步驟5前進,故在檢測到熄火為止,會反覆移往圖4之
步驟6。如此,火力控制部16可在沒有判定鍋底溫度感測器7之檢測溫度Tr是上昇或下降的情形下,選擇最佳之火力級別。
For example, when the current firepower level is "γ", proceed to step 12 in
而且,根據以上之控制,藉由火力控制部16,隨著檢測溫度Tr變高(接近目標溫度)而令火力級別變小,可較早減緩鍋9(調理容器)之溫度上昇,隨著檢測溫度Tr變低(遠離目標溫度)而令火力級別變大,可較早減緩鍋9(調理容器)之溫度下降,因此,可降低相較於目標溫度之鍋9(調理容器)之溫度變動幅度。
Moreover, according to the above control, the heating
話說,根據本實施形態之控制器3,當檢測溫度位於目標溫度之附近時,火力級別會自動地切換,但爐燃燒器2以與使用者手動設定之火力級別不同之火力級別進行燃燒控制可能會造成使用者感到困惑、誤以為是故障。
In other words, according to the
於是,本實施形態是如圖5所示,在操作旋鈕10之周圍設有由發光元件而成之複數個位置表示部10a、10b、10c、10d、10e,可藉由各位置表示部10a、10b、10c、10d、10e之發光形態而表示火力級別。附帶一提,該發光元件是採用可就2種顏色光而選擇性地發光之發光元件。
Therefore, in this embodiment, as shown in FIG. 5, a plurality of
各位置表示部10a、10b、10c、10d、10e是依照操作旋鈕10之預定之旋轉角度(操作量)而設,如圖1所示,藉由控制器3之位置表示控制部17來進行控制。
The
位置表示控制部17是使用5個位置表示部
10a、10b、10c、10d、10e來表示火力級別「1」~火力級別「9」之9階段。各位置表示部10a、10b、10c、10d、10e之發光形態是如圖6所示,當顯示火力級別「1」、「3」、「5」、「7」、「9」的情況下是亮燈狀態,當顯示火力級別「2」、「4」、「6」、「8」的情況下是閃爍狀態。
The position
而且,位置表示控制部17令顯示使用者手動設定之火力級別(亦包含事先設定之點火時之火力級別)之位置表示部之發光元件維持以藍色發光之狀態,令顯示由火力控制部16自動改變之火力級別之位置表示部之發光元件以紅色發光。
Furthermore, the position
根據此,可明確地分辨使用者手動設定之火力級別、由火力控制部16自動改變之火力級別,可防止使用者感到困惑、誤以為是故障。
According to this, the firepower level manually set by the user and the firepower level automatically changed by the
附帶一提,雖然在本實施形態顯示之例子是藉由溫度範圍設定部18而以能與目標溫度直接比較之實際溫度來設定與各火力級別對應之控制溫度範圍,但除此之外,與各火力級別對應之溫度範圍亦可以是使用與目標溫度之差之值來比較。亦即,具體而言,當火力控制部16之溫度範圍設定部18是以從目標溫度-5℃之間隔來設定各火力級別之使用判斷時之閾值的情況下,亦可以將與火力級別「9」對應之溫度差範圍設定在比目標溫度之-30℃大,將與火力級別「γ」對應之溫度差範圍設定在目標溫度之-20℃~-25℃,將與火力級別「β」對應之溫度差範
圍設定在目標溫度之-15℃~-20℃,將與火力級別「α」對應之溫度差範圍設定在目標溫度之-10℃~-15℃,將與火力級別「1」對應之溫度差範圍設定在目標溫度之-5℃以下。
Incidentally, although the example shown in this embodiment uses the temperature
另外,雖然本實施形態是針對瓦斯爐1進行說明,但本發明並非限定於瓦斯爐1,舉例來說,亦可以採用電磁調理器、電爐。當是電磁調理器、電爐的情況下,藉由換成如上述般之對爐燃燒器2之火力之控制而控制對感應加熱部、鎳鉻線加熱器之供給電力,可獲得與本實施形態相同之效果。
