Description
本発明は、電動調理器に関する。 The present invention relates to an electric cooker.
従来から、果物や野菜などの食材（以下、食材と言う）からジュースを作るジューサーや各種料理の下ごしらえなどのジュース以外の調理に用いるフードプロセッサーなどの電動調理器が知られている。電動調理器は、食材を収容する容器と、容器の底部に設けられた調理部材と、調理部材を駆動する駆動モータを内蔵した本体とを備えており、食材を収容した容器を本体に装着して、駆動モータで調理部材を回動させることで、容器内で食材を切削、粉砕、攪拌などの各種調理（以下、調理と言う）を行う。この電動調理器において、調理中に食材が空気と混ざり合い酸化して栄養成分が減少する問題があり、近年この問題を解決すべく鋭意研究されている（特許文献１）。 2. Description of the Related Art Conventionally, electric cookers such as a juicer for making juice from ingredients such as fruits and vegetables (hereinafter referred to as ingredients) and a food processor used for cooking other than juice such as preparing various dishes are known. The electric cooker includes a container for storing the food, a cooking member provided at the bottom of the container, and a main body including a drive motor for driving the cooking member, and the container containing the food is mounted on the main body. The cooking member is rotated by the drive motor to perform various kinds of cooking (hereinafter, referred to as cooking) such as cutting, crushing, and stirring the food in the container. In this electric cooker, during cooking, there is a problem that foodstuffs are mixed with air and oxidized to reduce nutrient components. In recent years, intensive studies have been made to solve this problem (Patent Document 1).
例えば、特許文献２（従来例）には、図１４に示すように、吸気手段１１６（切り替え弁１２０と吸引ポンプ１１６aを有するもの）を内部に設けた蓋１１５で、食材（不図示）を収容した容器１６０を覆い、吸引ポンプ１１６aで容器１６０内の空気を吸引して低酸素状態とした後に、切り替え弁１２０を切り替えて、カッター１９０で食材を切削し、食材の酸化による栄養成分の減少を防止する電動調理器１００が開示されている。 For example, in Patent Document 2 (conventional example), as shown in FIG. 14, food (not shown) is accommodated by a lid 115 provided inside with an intake means 116 (having a switching valve 120 and a suction pump 116a). After the container 160 is covered, the air in the container 160 is sucked by the suction pump 116a to make it in a low oxygen state, the switching valve 120 is switched, the food is cut by the cutter 190, and the nutrient component is reduced by the oxidation of the food. An electric cooker 100 is disclosed for preventing.
しかし、特許文献２に開示された電動調理器１００では、吸引ポンプ１１６a内に容器１６０内の空気が直接流入するため、吸引ポンプ１１６aの動作中において、カッター１９０で調理された細かい食材、調理中に生じた水滴、泡、および調理前から容器１６０内に付着した水滴が気化した水蒸気などの食材細片（以下、食材細片と言う）（不図示）が、吸引ポンプ１１６a内へ吸引されて、吸引ポンプ１１６aに不具合を起こす可能性があった。 However, in the electric cooker 100 disclosed in Patent Literature 2, since the air in the container 160 flows directly into the suction pump 116a, the fine ingredients cooked by the cutter 190 during the operation of the suction pump 116a, Food particles (hereinafter, referred to as food particles) (not shown) such as water droplets, bubbles, and water vapor attached to the inside of the container 160 and vaporized water droplets before cooking are sucked into the suction pump 116a. However, there is a possibility that a malfunction may occur in the suction pump 116a.
本発明は、上述した事情に鑑みてなされるものであって、吸引部を動作させる際に食材細片検出部で食材細片を検出しながら、容器内を低酸素状態として食材を調理することで、食材の酸化による栄養成分の減少を防ぐとともに、吸引部内に食材細片が吸引されることを防ぎ、吸引部の耐久性を向上させることができる電動調理器を提供することである。 The present invention has been made in view of the above-described circumstances, and is to cook food with a low oxygen state inside a container while detecting a food strip with a food strip detection unit when operating a suction unit. Accordingly, it is an object of the present invention to provide an electric cooker that can prevent a decrease in nutrient components due to oxidation of a food material, prevent a small piece of food material from being sucked into a suction unit, and improve durability of the suction unit.

With this configuration, when the sealing oscillating valve 52 is pushed up by a food strip (not shown) or the like, the electric cooking device 1 of the present embodiment smoothly closes the sealing oscillating valve 52 at the sealing position (FIG. 3B).

When the valve 52 is located at the separated position, a space is formed between the sealing oscillating valve 52 and the bottom surface of the sealing valve accommodating portion 55a to secure an air passage from the container 2 to the suction portion 45. Thus, the air in the container 2 can be reliably sucked by the suction unit 45.
また、本実施例の電動調理器１は、封止揺動弁５２を単に支持突起５５eで支持し、かつ封止揺動弁５２の底面をリブ構造にすることで、容器２内に多量の食材細片が発生した際に、食材細片が封止揺動弁５２の底面を押し上げて、図３Ｂに示す封止位置へ移動させることができる。具体的には、本実施例の電動調理器１は、容器２内に多量の食材細片、特に泡が発生して、蓋体５の近くまで上昇した際に、この泡が封止揺動弁５２を押し上げて、図３Ｂに示すように突出ノズル部５１aを封止し、食材細片が突出ノズル部５１a内に流入することを防ぐことができる。 Further, the electric cooker 1 of this embodiment simply supports the sealing oscillating valve 52 with the support protrusion 55e, and the bottom surface of the sealing oscillating valve 52 has a rib structure, so that a large amount of When a food strip is generated, the food strip can push up the bottom surface of the sealing oscillating valve 52 and move it to the sealing position shown in FIG. 3B. Specifically, the electric cooking device 1 of the present embodiment is configured such that when a large amount of food particles, particularly bubbles, are generated in the container 2 and rise to the vicinity of the lid 5, the bubbles are sealed and rocked. By pushing up the valve 52, the protruding nozzle portion 51a is sealed as shown in FIG. 3B, so that the food strip can be prevented from flowing into the protruding nozzle portion 51a.

The pressure detection unit 11 detects the pressure in the container 2 via the ventilation tube 46 at predetermined intervals, and transmits the detected pressure (hereinafter, referred to as detected pressure) to the control unit 13.
操作入力部１２は、使用者からの各種操作入力を受け付け、入力情報を制御部１３へ送信する。操作入力部１２は、図２に示すように、例えば水平基部４１の前側に設けられている。 The operation input unit 12 receives various operation inputs from the user and transmits input information to the control unit 13. The operation input unit 12 is provided, for example, on the front side of the horizontal base 41 as shown in FIG.
記憶部は、例えば、ＨＤＤ（Ｈａｒｄ Ｄｉｓｋ Ｄｒｉｖｅ）、ＭｅｍｏｒｙまたはＲＡＭ（Ｒａｎｄｏｍ Ａｃｃｅｓｓ Ｍｅｍｏｒｙ）などであり、電動調理器１の各種調理モード（例えば、真空調理動作モード（容器２内を所定の圧力にして食材を調理部材３で調理するモード）や真空保存動作モード（容器２内を所定の圧力にして食材および食材細片を保存するモード）など）を記憶している。記憶部内には、操作入力部１２からの入力情報に対応付けて、各種調理モードにおける、調理部材３が動作する設定時間（以下、設定時間と言う）、調理部材３を回動させる設定回動速度（以下、設定回動速度と言う）、および調理部材３の動作中における容器２内の設定圧力（以下、設定圧力と言う）などが記憶されている。 The storage unit is, for example, a hard disk drive (HDD), a memory, a random access memory (RAM), or the like, and stores various cooking modes of the electric cooker 1 (for example, a vacuum cooking operation mode (by setting the inside of the container 2 to a predetermined pressure). The mode stores a mode in which the food is cooked by the cooking member 3) and a vacuum storage operation mode (a mode in which the food and the food pieces are stored by applying a predetermined pressure to the inside of the container 2). In the storage unit, a set time for operating the cooking member 3 in various cooking modes (hereinafter, referred to as a set time) and a setting rotation for rotating the cooking member 3 are associated with input information from the operation input unit 12. A speed (hereinafter, referred to as a set rotation speed), a set pressure in the container 2 during operation of the cooking member 3 (hereinafter, referred to as a set pressure), and the like are stored.
時間計測部は、例えば計測タイマーなどであり、吸引部４５の動作が開始した後に時間を計測し、制御部１３へ計測時間を送信する。この時間計測部は、吸引部４５の動作時間および駆動部４４の駆動時間を計測する。 The time measurement unit is, for example, a measurement timer, and measures the time after the operation of the suction unit 45 starts, and transmits the measurement time to the control unit 13. The time measuring unit measures the operating time of the suction unit 45 and the driving time of the driving unit 44.
制御部１３は、図２に示すように、例えばＣＰＵ（Ｃｅｎｔｒａｌ Ｐｒｏｃｅｓｓｉｎｇ Ｕｎｉｔ）などであり、駆動部４４、吸引部４５、圧力検出部１１、操作入力部１２、時間計測部および記憶部に電気的に接続されている。この制御部１３は、設定時間、設定圧力、設定回動速度、計測時間および検出圧力等に応じて、駆動部４４および吸引部４５の動作を制御する。具体的には、制御部１３は、操作入力部１２からの入力情報を取得すると、この入力情報に対応する調理モードに関する情報（設定時間、設定回動速度、設定圧力など）を記憶部から取得して、この取得した情報（設定時間、設定回動速度、設定圧力など）に基づいて、駆動部４４および吸引部４５を動作させる。また、制御部１３は、後述の環境圧力判定と後述の平均圧力差判定を組み合わせて、異常状態を判定して、吸引部４５の動作を停止させる。 The control unit 13 is, for example, a CPU (Central Processing Unit), as shown in FIG. 2, and is electrically connected to the drive unit 44, the suction unit 45, the pressure detection unit 11, the operation input unit 12, the time measurement unit, and the storage unit. It is connected to the. The control unit 13 controls the operations of the driving unit 44 and the suction unit 45 according to the set time, the set pressure, the set rotation speed, the measurement time, the detected pressure, and the like. Specifically, when acquiring the input information from the operation input unit 12, the control unit 13 acquires information (set time, set rotation speed, set pressure, etc.) regarding the cooking mode corresponding to the input information from the storage unit. Then, the drive unit 44 and the suction unit 45 are operated based on the acquired information (set time, set rotation speed, set pressure, and the like). Further, the control unit 13 determines an abnormal state by combining an environmental pressure determination described below and an average pressure difference determination described below, and stops the operation of the suction unit 45.
なお、異常状態とは、吸引部４５が吸引動作中において、容器２内に発生した食材細片、特に泡で、封止揺動弁５２が押し上げられて、図３Ａの離間位置から図３Ｂの封止位置へ封止揺動弁５２が移動した状態や、食材細片による突出ノズル部５１aへ向かう流れが生じた状態のことである。 In addition, the abnormal state is a state in which the sealing oscillating valve 52 is pushed up by the food flakes, particularly bubbles, generated in the container 2 during the suction operation of the suction unit 45, and from the separated position in FIG. This refers to a state in which the sealing swing valve 52 has moved to the sealing position, or a state in which a flow toward the protruding nozzle portion 51a due to small food particles has occurred.
このように、本実施例の電動調理器１は、調理モードに応じて、容器２内の設定圧力、調理部材３の設定回動速度および設定時間を変化させることで、容器２内に収容された食材に対して各種調理モードに適した調理を行うことができる。 As described above, the electric cooker 1 of the present embodiment is accommodated in the container 2 by changing the set pressure in the container 2, the set rotation speed and the set time of the cooking member 3 according to the cooking mode. It is possible to perform cooking suitable for various cooking modes on the prepared food.
次に、本実施例の電動調理器１における制御部１３の異常状態の判定方法（環境圧力判定および平均圧力差判定）について説明する。初期条件として、食材を収容した容器２を本体４に装着し、駆動側伝達部４４ｂと容器側伝達部３２が噛み合い、駆動部４４の駆動力を調理部材３へ伝達できる状態とする。また、本体４の開口端部には蓋体５が嵌合されており、係合爪４３ｂが突出ノズル部５１aに係合されており、回動接続部４３と蓋体５が一体的に固定されているものとする。 Next, a method of determining an abnormal state of the control unit 13 in the electric cooker 1 of the present embodiment (environmental pressure determination and average pressure difference determination) will be described. As an initial condition, the container 2 containing the food is mounted on the main body 4 so that the drive-side transmission unit 44b and the container-side transmission unit 32 are engaged with each other, so that the driving force of the drive unit 44 can be transmitted to the cooking member 3. The lid 5 is fitted to the opening end of the main body 4, the engaging claw 43 b is engaged with the protruding nozzle 51 a, and the rotary connection portion 43 and the lid 5 are integrally fixed. It is assumed that
図９は、図１の電動調理器１における異常状態の判定方法を示す制御フローチャートである。 FIG. 9 is a control flowchart illustrating a method of determining an abnormal state in the electric cooker 1 of FIG.
＜環境圧力判定＞
制御部１３は、吸引部４５の動作開始前において圧力検出部１１で検出圧力を検出して、開始圧力Ｐstartとし、境界圧力値Ｐlimitを０に設定する（ＳＴＥＰ１、２、３）。制御部１３は、吸引部４５を動作させると、所定時間（a（ｓ））の間に受信した複数の検出圧力の平均値を算出して、圧力平均値Ｐｍ（０）を算出する（ＳＴＥＰ４ＹＥＳ、ＳＴＥＰ５）。同様に、制御部１３は、次の所定時間（a（ｓ））の間に受信した複数の検出圧力の平均値を算出して、次の圧力平均値Ｐｍ（１）を算出する（ＳＴＥＰ６）。
<Environmental pressure judgment>
The control unit 13 detects the detected pressure by the pressure detection unit 11 before starting the operation of the suction unit 45, sets the detected pressure as the start pressure Pstart, and sets the boundary pressure value Plimit to 0 (STEPs 1, 2, and 3). When operating the suction unit 45, the control unit 13 calculates the average value of the plurality of detected pressures received during the predetermined time (a (s)), and calculates the average pressure value Pm (0) (STEP 4 YES). , STEP5). Similarly, the control unit 13 calculates the average value of the plurality of detected pressures received during the next predetermined time (a (s)), and calculates the next pressure average value Pm (1) (STEP 6). .
制御部１３は、圧力平均値Ｐｍ（０）から次の圧力平均値Ｐｍ（１）を減算して、平均圧力差Ｐｄ（0’）を算出する（ＳＴＥＰ７）。平均圧力差Ｐｄ（0’）を算出すると、制御部１３は、相対圧力（標準大気圧Ｐ０（１０１．３ｋＰａ）を開始圧力Ｐstartで除算したもの）を平均圧力差Ｐｄ（0’）に乗算して、相対平均圧力差Ｐｄ（０）を算出する（ＳＴＥＰ８）。制御部１３は、この相対平均圧力差Ｐｄ（０）が１ｋＰaより大きいか否かを判定する（ＳＴＥＰ９）。 The control unit 13 calculates the average pressure difference Pd (0 ') by subtracting the next average pressure value Pm (1) from the average pressure value Pm (0) (STEP 7). After calculating the average pressure difference Pd (0 ′), the control unit 13 multiplies the average pressure difference Pd (0 ′) by the relative pressure (the standard atmospheric pressure P0 (101.3 kPa) divided by the start pressure Pstart). Then, the relative average pressure difference Pd (0) is calculated (STEP 8). The control unit 13 determines whether or not the relative average pressure difference Pd (0) is larger than 1 kPa (STEP 9).
制御部１３が、相対平均圧力差Ｐｄ（０）が１ｋＰa以下と判定した場合には、再度、所定時間に受信した複数の検出圧力の圧力平均値を算出し（ＳＴＥＰ９Ｎｏ、ＳＴＥＰ５）、ＳＴＥＰ６、７、８および９の処理を繰り返す。また、制御部１３が、相対平均圧力差Ｐｄ（０）が、１ｋＰaよりも大きいと判定した場合には、次の平均圧力差判定へ進む（ＳＴＥＰ９ＹＥＳ）。 When the control unit 13 determines that the relative average pressure difference Pd (0) is equal to or less than 1 kPa, it calculates again the average pressure values of the plurality of detected pressures received during the predetermined time (STEP 9 No, STEP 5), and STEPs 6 and 7. , 8 and 9 are repeated. When the controller 13 determines that the relative average pressure difference Pd (0) is larger than 1 kPa, the process proceeds to the next average pressure difference determination (STEP 9 YES).
＜平均圧力差判定＞
制御部１３は、相対平均圧力差Ｐｄ（０）が１ｋＰａよりも大きいと判定すると、再度所定時間（a（s））の間に受信した複数の検出圧力の平均値を算出して、圧力平均値（Ｐｍ（ｎ））とする（ＳＴＥＰ９ＹＥＳ、ＳＴＥＰ１０）。制御部１３は、同様に、次の所定時間（a（s））の間に受信した複数の検出圧力の平均値を算出し、次の圧力平均値（Ｐｍ（ｎ＋１））とする（ＳＴＥＰ１１）。
<Average pressure difference judgment>
When determining that the relative average pressure difference Pd (0) is larger than 1 kPa, the control unit 13 calculates again the average value of the plurality of detected pressures received during the predetermined time (a (s)), and The value (Pm (n)) is set (STEP 9 YES, STEP 10). The control unit 13 similarly calculates the average value of the plurality of detected pressures received during the next predetermined time (a (s)) and sets the average value as the next pressure average value (Pm (n + 1)) (STEP 11). .
制御部１３は、圧力平均値（Ｐｍ（ｎ））から次の圧力平均値（Ｐｍ（ｎ＋１））を減算して、平均圧力差Ｐｄ（ｎ）を算出する（ＳＴＥＰ１２）。制御部１３は、環境圧力判定で算出した最初の相対平均圧力差Ｐｄ（０）に対して閾値（例えば、閾値＝４）と圧力平均値（Ｐｍ（n））を乗算するとともに、標準大気圧Ｐ0で除算して、境界圧力値Ｐlimitを算出する（ＳＴＥＰ１３）。制御部１３は、この算出した境界圧力値Ｐlimitが平均圧力差Ｐｄ（ｎ）より小さいか否かを判定する（ＳＴＥＰ１４）。 The control unit 13 calculates the average pressure difference Pd (n) by subtracting the next average pressure value (Pm (n + 1)) from the average pressure value (Pm (n)) (STEP 12). The control unit 13 multiplies the initial relative average pressure difference Pd (0) calculated in the environmental pressure determination by a threshold value (for example, threshold value = 4) and a pressure average value (Pm (n)), The boundary pressure value Plimit is calculated by dividing by P0 (STEP 13). The control unit 13 determines whether or not the calculated boundary pressure value Plimit is smaller than the average pressure difference Pd (n) (STEP 14).
制御部１３が、境界圧力値Ｐlimitが平均圧力差Ｐｄ（ｎ）より大きいと判定すると、再度、制御部１３は、所定時間（a（ｓ））の間において受信した複数の検出圧力の平均値を算出して、圧力平均値に設定して（ＳＴＥＰ１４ＮＯ、ＳＴＥＰ１０）、ＳＴＥＰ１１、１２、１３および１４の処理を繰り返す。制御部１３が、境界圧力値Ｐlimitが平均圧力差Ｐｄ（ｎ）以下と判定すると、制御部１３は吸引部４５の吸引動作を停止させて、異常状態の判定を終了する（ＳＴＥＰ１４ＹＥＳ、ＳＴＥＰ１５、１６）。 When the control unit 13 determines that the boundary pressure value Plimit is larger than the average pressure difference Pd (n), the control unit 13 again determines the average value of the plurality of detected pressures received during the predetermined time (a (s)). Is calculated and set as the pressure average value (STEP 14 NO, STEP 10), and the processing of STEPs 11, 12, 13, and 14 is repeated. When the control unit 13 determines that the boundary pressure value Plimit is equal to or smaller than the average pressure difference Pd (n), the control unit 13 stops the suction operation of the suction unit 45 and ends the determination of the abnormal state (STEP 14 YES, STEPs 15 and 16). ).
本実施例の電動調理器１は、圧力検出部１１からの検出圧力のみを用いて異常状態を判定するため、単に電気抵抗を電気信号に変換する圧力センサを圧力検出部１１とした場合においても、確実に異常状態を検出することができる。 Since the electric cooking device 1 of the present embodiment determines an abnormal state using only the detected pressure from the pressure detection unit 11, even if the pressure sensor that simply converts the electric resistance into an electric signal is used as the pressure detection unit 11, Thus, an abnormal state can be reliably detected.
本実施例の電動調理器１は、圧力検出部１１による容器２内の圧力を検出して異常状態を判定して、駆動部４４を停止させるため、突出ノズル部５１aへ向かう食材細片の流れを通気チューブ４６に流入する前で規制することができる。 The electric cooker 1 according to the present embodiment detects the pressure in the container 2 by the pressure detecting unit 11 to determine an abnormal state and stops the driving unit 44, so that the flow of the food strip toward the protruding nozzle 51a is stopped. Before flowing into the ventilation tube 46.
本実施例の電動調理器１は、環境圧力判定をも含めて異常状態を判定することで、環境要素による圧力差（例えば、使用場所の高低差による圧力差）を考慮して、異常状態を判定することができる。 The electric cooker 1 of the present embodiment determines an abnormal state by determining the abnormal state including the environmental pressure determination, and takes into account a pressure difference due to environmental factors (for example, a pressure difference due to a height difference at a place of use). Can be determined.
また、本実施例の電動調理器１は、平均圧力差判定の前に環境圧力判定を行うことで、明らかに異常状態ではない場合（ノイズ）を除外して、異常状態判定を迅速に行うことができる。 Further, the electric cooking device 1 of the present embodiment performs the environmental pressure judgment before the average pressure difference judgment, thereby excluding a case where the abnormal state is not clearly abnormal (noise) and quickly performing the abnormal state judgment. Can be.
さらに、本実施例の電動調理器１は、常に圧力傾斜が変動するような検出が難しい状態においても、制御部１３が、境界圧力値Ｐlimitと平均圧力差Ｐｄ（ｎ）とを比較して異常状態を判定するため、正確に異常状態を判定することができる。すなわち、本実施例の電動調理器１は、圧力検出部１１における検出圧力を用いて算出した境界圧力値Ｐlimitや平均圧力差Ｐｄ（ｎ）などを用いて、正確に判定することができる。
なお、制御部１３による上記異常状態の判定方法は、真空調理動作モードおよび真空保存動作モードの両方において適用される。
Further, in the electric cooker 1 of the present embodiment, even in a state where it is difficult to detect such that the pressure gradient always fluctuates, the control unit 13 compares the boundary pressure value Plimit with the average pressure difference Pd (n) and detects an abnormality. Since the state is determined, the abnormal state can be accurately determined. That is, the electric cooker 1 according to the present embodiment can accurately determine the boundary pressure value Plimit calculated using the pressure detected by the pressure detection unit 11, the average pressure difference Pd (n), and the like.
The method of determining an abnormal state by the control unit 13 is applied in both the vacuum cooking operation mode and the vacuum storage operation mode.
次に、本実施例の電動調理器１における調理動作について説明する。初期条件として、食材を収容した容器２を本体４に装着し、駆動側伝達部４４ｂと容器側伝達部３２が噛み合い、駆動部４４の駆動力を調理部材３へ伝達できる状態とする。また、本体４の開口端部には蓋体５が嵌合されており、係合爪４３ｂが突出ノズル部５１aに係合されており、回動接続部４３と蓋体５が一体的に固定されているものとする。 Next, a cooking operation in the electric cooker 1 of the present embodiment will be described. As an initial condition, the container 2 containing the food is mounted on the main body 4 so that the drive-side transmission unit 44b and the container-side transmission unit 32 are engaged with each other, so that the driving force of the drive unit 44 can be transmitted to the cooking member 3. The lid 5 is fitted to the opening end of the main body 4, the engaging claw 43 b is engaged with the protruding nozzle 51 a, and the rotary connection portion 43 and the lid 5 are integrally fixed. It is assumed that
図１０は、図１の電動調理器１の調理動作を示す制御フローチャートである。 FIG. 10 is a control flowchart showing a cooking operation of the electric cooker 1 of FIG.
図１０に示すように、制御部１３は、まず、操作入力部１２に入力情報が入力されたか否かを判定する（ＳＴＥＰ２１、２２）。制御部１３が操作入力部１２から入力情報を取得すると（ＳＴＥＰ２２ＹＥＳ）、制御部１３は、記憶部から入力情報に対応する、設定圧力、設定時間および設定回動速度に関する情報を取得して、吸引部４５および時間計測部を動作させる（ＳＴＥＰ２３、２４）。制御部１３は、圧力検出部１１から異常検出状態でないかを判定する（ＳＴＥＰ２４）。具体的には、制御部１３は、環境圧力判定および平均圧力差判定を行い、異常状態でないか否かを判定する。 As shown in FIG. 10, the control unit 13 first determines whether or not input information has been input to the operation input unit 12 (STEPs 21 and 22). When the control unit 13 obtains input information from the operation input unit 12 (STEP 22 YES), the control unit 13 obtains information on the set pressure, the set time, and the set rotation speed corresponding to the input information from the storage unit, and performs suction. The unit 45 and the time measuring unit are operated (STEPs 23 and 24). The control unit 13 determines whether the pressure detection unit 11 is in an abnormal detection state (STEP 24). Specifically, the control unit 13 performs the environmental pressure determination and the average pressure difference determination, and determines whether or not there is an abnormal state.
制御部１３が、異常状態でないと判定すると（ＳＴＥＰ２５ＮＯ）、制御部１３は、時間計測部における吸引部４５の動作時間が所定時間（例えば３分）を経過したか否かを判定する（ＳＴＥＰ２６）。制御部１３が、時間計測部で計測した吸引部４５の動作時間が所定時間を経過したと判定すると（ＳＴＥＰ２６ＮＯ）、圧力検出部１１の検出圧力が設定圧力よりも高いか否かを判定する（ＳＴＥＰ２７）。ここで、制御部１３が異常状態と判定した場合（ＳＴＥＰ２５ＹＥＳ）や吸引部４５の動作時間が所定時間を経過したと判定した場合（ＳＴＥＰ２６ＹＥＳ）には、制御部１３は吸引部４５を停止させて、調理動作を終了する（ＳＴＥＰ２１、ＳＴＥＰ２２）。 When the control unit 13 determines that the state is not abnormal (STEP 25 NO), the control unit 13 determines whether the operation time of the suction unit 45 in the time measurement unit has passed a predetermined time (for example, 3 minutes) (STEP 26). . When the control unit 13 determines that the operation time of the suction unit 45 measured by the time measurement unit has exceeded the predetermined time (STEP 26 NO), it determines whether the pressure detected by the pressure detection unit 11 is higher than the set pressure (step 26). (STEP 27). Here, when the control unit 13 determines that the suction unit 45 is in an abnormal state (STEP 25 YES) or when the operation time of the suction unit 45 has elapsed a predetermined time (STEP 26 YES), the control unit 13 stops the suction unit 45. Then, the cooking operation ends (STEP21, STEP22).
本実施例の電動調理器１は、吸引部４５が所定時間を越えて動作する場合に、吸引部４５を停止させることで、吸引部４５の動作による過負荷を防止することができる。 In the electric cooker 1 according to the present embodiment, when the suction unit 45 operates for more than the predetermined time, by stopping the suction unit 45, it is possible to prevent an overload due to the operation of the suction unit 45.
制御部１３は、圧力検出部１１の検出圧力が設定圧力以下と判定すると（ＳＴＥＰ２７ＮＯ）、吸引部４５の動作を停止させ、駆動部４４を動作させ、時間計測部で駆動部４４の動作時間を計測する（ＳＴＥＰ２８、ＳＴＥＰ２９）。駆動部４４を動作させた後、制御部１３は、時間計測部における駆動部４４の動作時間が設定時間を経過したか否かを判定する（ＳＴＥＰ３０）。制御部１３が、時間計測部における駆動部４４の動作時間が設定時間を経過していないと判定した場合は、再度時間判定を行う（ＳＴＥＰ３０ＮＯ、Ｓ
ＴＥＰ３０）。
When the control unit 13 determines that the pressure detected by the pressure detection unit 11 is equal to or lower than the set pressure (STEP 27 NO), the control unit 13 stops the operation of the suction unit 45, operates the drive unit 44, and sets the operation time of the drive unit 44 by The measurement is performed (STEP 28, STEP 29). After operating the drive unit 44, the control unit 13 determines whether or not the operation time of the drive unit 44 in the time measurement unit has exceeded the set time (STEP 30). When the control unit 13 determines that the operation time of the drive unit 44 in the time measurement unit has not exceeded the set time, the time determination is performed again (STEP 30 NO, S
TEP30).
制御部１３が、時間計測部の計測時間が設定時間を経過したと判定すると、駆動部４４を停止させて、調理動作を終了する（ＳＴＥＰ３０ＹＥＳ、ＳＴＥＰ３２、ＳＴＥＰ３３）。 When the control unit 13 determines that the time measured by the time measurement unit has exceeded the set time, the control unit 13 stops the driving unit 44 and ends the cooking operation (STEP 30 YES, STEP 32, STEP 33).
本実施例の電動調理器１は、吸引部４５の動作中において、異常状態か否かを判定して、食材細片が突出ノズル部５１aへ流入する前に、吸引部４５の動作を停止させることで、吸引部４５内へ食材細片が流入し、吸引部４５の耐久性が短くなることを防止することができる。特に、本実施例の電動調理器１において、食材を調理中に食材細片が突出ノズル部５１ａ側へ移動した際には、この移動する食材細片により封止揺動弁５２が押し上げられて、突出ノズル部５１aを封止することで、圧力検出部１１が異常信号を制御部１３へ送信して、制御部１３は吸引部４５の動作を停止させて、吸引部４５内へ食材が吸入されることを防ぎ、吸引部４５の耐久性を向上させることができる。 The electric cooker 1 according to the present embodiment determines whether or not the suction unit 45 is in an abnormal state during the operation of the suction unit 45, and stops the operation of the suction unit 45 before the food strip flows into the protruding nozzle 51a. Thus, it is possible to prevent the small food ingredients from flowing into the suction unit 45 and shortening the durability of the suction unit 45. In particular, in the electric cooker 1 of the present embodiment, when the food strip moves toward the protruding nozzle portion 51a while cooking the food, the sealing swing valve 52 is pushed up by the moving food strip. By sealing the protruding nozzle portion 51a, the pressure detecting portion 11 transmits an abnormal signal to the control portion 13, and the control portion 13 stops the operation of the suction portion 45, and the food is sucked into the suction portion 45. And the durability of the suction part 45 can be improved.
また、本実施例の電動調理器１は、吸引部４５により容器２内を低酸素状態にすることができるため、調理中に食材が酸化して栄養成分が減少することも防ぐことができる。 Further, in the electric cooker 1 of the present embodiment, since the inside of the container 2 can be brought into a low-oxygen state by the suction unit 45, it is possible to prevent the oxidization of food ingredients during cooking and a decrease in nutritional components.

When the control unit 13 ′ determines that the temperature detected by the temperature detection unit 14 has rapidly changed, the control unit 13 ′ determines that the temperature is abnormal, and stops the operation of the driving unit 44 and the suction unit 45.
この構成により、本実施例の電動調理器１’は、食材細片が囲い壁５５hを乗り越えて、突出ノズル部５１a内へ流入する場合においても、温度検出部１４における検出温度が急激に変化することで、制御部１３’は異常状態を正確に判定して、駆動部４４および吸引部４５の動作を停止させ、吸引部４５内へ食材細片が侵入することを防ぎ、吸引部４５の耐久性を向上させることができる。 With this configuration, in the electric cooker 1 ′ of the present embodiment, the temperature detected by the temperature detection unit 14 rapidly changes even when the food strips get over the surrounding wall 55 h and flow into the protruding nozzle 51 a.

The collision causes the momentum to be reduced, so that the food strips and the water vapor can be stored in the food strip storage section 55g.
さらに、本実施例の電動調理器１’は、食材細片、特に水蒸気が囲い壁５５hを超えて突出ノズル部５１aの内壁面に付着して、電動調理器１’の動作後冷却されて液化した場合に、この液化した食材細片を食材細片収容部５５g内に収容することができる。 Further, in the electric cooker 1 'of the present embodiment, the small food ingredients, particularly the steam, adhere to the inner wall surface of the protruding nozzle portion 51a beyond the surrounding wall 55h, and are cooled and liquefied after the operation of the electric cooker 1'. In this case, the liquefied food strip can be stored in the food strip storage section 55g.
