Description
本發明涉及一種包括防止水槽的異常振動的安全裝置的洗衣機。 The present invention relates to a washing machine including a safety device for preventing abnormal vibration of a water tank.
在洗衣機的脫水時等，有因旋轉槽內的洗滌物的偏置等而旋轉槽以及水槽的搖動變大，產生異常振動的情況。以往，為了防止如此的異常振動，在水槽的搖動超過規定量的情況偵測此而使運轉停止的安全裝置被包括在洗衣機。 When a washing machine is spinning, the rotation tank and the water tank may shake more due to the offset of the laundry in the rotation tank, causing abnormal vibration. In the past, in order to prevent such abnormal vibration, a safety device was included in the washing machine that detects and stops the operation when the shaking of the water tank exceeds a specified amount.
在專利文獻1，揭示了：在水槽的外側設置機械式的開關桿(switch lever)，在水槽的搖動超過規定量的情況藉由水槽與開關桿抵接而判斷異常振動的安全裝置。 Patent document 1 discloses a safety device that provides a mechanical switch lever on the outside of a water tank, and determines abnormal vibration by causing the water tank to contact the switch lever when the water tank shakes beyond a specified amount.
專利文獻1：日本特開平第9-28981號公報。 Patent document 1: Japanese Patent Publication No. 9-28981.
機械式的開關桿是接觸發生了搖動的水槽的外周側面而判斷異常振動者。但是，由於機械式的開關桿理當是將從初期位置至振動偵測位置的動作範圍設為必要者，若不是產生某種程度的大的位移的搖動則無法偵測。又，機械式的開關桿，因在洗衣機的長年使用中重複與水槽的接觸，其安裝位置也可能相對於水槽移動至外周側。若開關桿的安裝位置如此地移動，則成為可偵測的水槽的位移進一步變大(振動的偵測精度變低)。 The mechanical switch lever is the one that contacts the outer side of the shaking sink to judge abnormal vibration. However, since the mechanical switch lever is supposed to have a necessary range of motion from the initial position to the vibration detection position, it cannot detect the shaking unless it causes a certain degree of large displacement. In addition, the mechanical switch lever may move to the outer side relative to the sink due to repeated contact with the sink during the long-term use of the washing machine. If the mounting position of the switch lever moves in this way, the displacement of the sink that can be detected will become larger (the detection accuracy of the vibration will decrease).
此外，為了謀求洗衣機的省空間化，期望水槽與外槽(洗衣機框體)之間的空間盡可能地小。若水槽與外槽之間的空間為小，則在使用機械式 的開關桿的安全裝置中，在偵測到水槽的異常振動而停止運轉前，發生了搖動的水槽碰撞到外槽，發生了大的噪音，或根據情況在外槽產生變形。 In order to save space in a washing machine, the space between the water tank and the outer tank (washing machine frame) is expected to be as small as possible. If the space between the water tank and the outer tank is small, the shaking water tank collides with the outer tank before the abnormal vibration of the water tank is detected and the operation is stopped in the safety device using a mechanical switch lever, resulting in a loud noise or deformation of the outer tank depending on the situation.
本發明是鑑於上述課題而成者，目的在於提供一種在水槽與外槽的碰撞產生前，能夠確實地偵測水槽的異常振動的洗衣機。 The present invention is made in view of the above-mentioned problem, and its purpose is to provide a washing machine that can accurately detect abnormal vibration of the water tank before the collision between the water tank and the outer tank occurs.
為了解決上述的課題，本發明是在外槽的內部配置水槽，在該水槽的內部配置旋轉槽的洗衣機，其包含：至少一個的測距感測器，在該水槽安裝；藉由該測距感測器，測量既定的方向的該外槽的內壁與測距感測器的距離；基於該測距感測器的測量值偵測該水槽的異常振動，在偵測到該水槽的異常振動的情況停止運轉。 In order to solve the above-mentioned problem, the present invention is a washing machine in which a water tank is arranged inside an outer tank, and a rotating tank is arranged inside the water tank, which comprises: at least one distance sensor installed in the water tank; the distance between the inner wall of the outer tank and the distance sensor in a predetermined direction is measured by the distance sensor; based on the measurement value of the distance sensor, abnormal vibration of the water tank is detected, and the operation is stopped when abnormal vibration of the water tank is detected.
根據上述的構成，對水槽安裝測距感測器，基於測距感測器的測量值(外槽的內壁與測距感測器的距離)偵測水槽的異常振動。在這個情況，藉由使用以非接觸來測量距離的測距感測器，能夠也偵測位移小的水槽的搖動，能夠在水槽與外槽的碰撞產生前確實地偵測水槽的異常振動，防止水槽與外槽的碰撞。又，以非接觸來測量距離的測距感測器基本上不是產生與外槽的接觸者。因此，測距感測器的安裝位置在洗衣機的長年使用中沒有變化，能夠維持高的偵測精度。 According to the above-mentioned structure, a distance sensor is installed on the water tank, and abnormal vibration of the water tank is detected based on the measurement value of the distance sensor (the distance between the inner wall of the outer tank and the distance sensor). In this case, by using a distance sensor that measures distance in a non-contact manner, it is possible to detect the shaking of the water tank with a small displacement, and it is possible to accurately detect the abnormal vibration of the water tank before the collision between the water tank and the outer tank occurs, thereby preventing the collision between the water tank and the outer tank. In addition, the distance sensor that measures distance in a non-contact manner basically does not come into contact with the outer tank. Therefore, the installation position of the distance sensor does not change during the long-term use of the washing machine, and high detection accuracy can be maintained.
又，能夠設為：該洗衣機包含兩個該測距感測器，該兩個測距感測器在俯視下測量方向為互相正交的構成。 Furthermore, it can be configured that: the washing machine includes two distance measuring sensors, and the measurement directions of the two distance measuring sensors are orthogonal to each other when viewed from above.
根據上述的構成，由於藉由兩個測距感測器可進行在正交的二方向中搖動的偵測，不論水槽的搖動在哪個方向產生都能夠偵測搖動而更確實地防止水槽的異常振動。 According to the above structure, since the two distance measuring sensors can detect the shaking in two orthogonal directions, the shaking of the water tank can be detected regardless of the direction in which the shaking occurs, thereby more reliably preventing abnormal vibration of the water tank.
又，在上述洗衣機中，能夠設為：至少一個該測距感測器是，其測量方向朝向該水槽的外周方向，測量與在最靠近該測距感測器的位置的該外槽的內壁的距離的構成。 Furthermore, in the above-mentioned washing machine, it can be configured that: at least one of the distance measuring sensors is configured to measure the distance to the inner wall of the outer tank at the position closest to the distance measuring sensor, with its measurement direction facing the outer circumference of the water tank.
根據上述的構成，由於藉由測距感測器測量的距離變短，能夠使用三角測量型等的便宜的感測器作為測距感測器。 According to the above-mentioned structure, since the distance measured by the distance measuring sensor becomes shorter, it is possible to use an inexpensive sensor such as a triangulation type as the distance measuring sensor.
又，在上述洗衣機中，能夠設為：至少一個該測距感測器是，安裝在該水槽的上表面，且其測量方向朝向該水槽的內周方向，測量該測距感測器與在最分離的位置的該外槽的內壁的距離的構成。 Furthermore, in the above-mentioned washing machine, it can be configured that: at least one of the distance measuring sensors is installed on the upper surface of the water tank, and its measuring direction is toward the inner circumference of the water tank, and the distance between the distance measuring sensor and the inner wall of the outer tank at the most separated position is measured.
根據上述的構成，除了藉由測距感測器偵測水槽的異常振動之外，也能夠偵測來自旋轉槽的洗滌物的飛出。 According to the above structure, in addition to detecting abnormal vibration of the water tank by the distance measuring sensor, it is also possible to detect the flying of laundry from the spinning tank.
本發明的洗衣機藉由使用以非接觸來測量距離的測距感測器，能夠也偵測位移小的水槽的搖動，起到能夠在水槽與外槽的碰撞產生前確實地偵測水槽的異常振動的功效。又，以非接觸來測量距離的測距感測器是，測距感測器的安裝位置在洗衣機的長年使用中沒有變化，一併起到能夠維持高的偵測精度的功效。 The washing machine of the present invention can detect the shaking of the water tank with small displacement by using a distance measuring sensor that measures distance non-contactly, and can accurately detect abnormal vibration of the water tank before the water tank collides with the outer tank. In addition, the installation position of the distance measuring sensor that measures distance non-contactly does not change during the long-term use of the washing machine, and can also maintain high detection accuracy.

[實施方式1] [Implementation Method 1]
以下，針對本發明的實施方式，參照圖式並進行詳細地說明。圖1是表示本實施方式1的洗衣機10的概略構成的圖，(a)是從側面側觀察洗衣機10的示意剖面圖，(b)是從正面側觀察洗衣機10的示意剖面圖，(c)是從上表面側觀察洗衣機10的內部(拆下了蓋部16的狀態)的示意圖。 Hereinafter, the embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing the schematic structure of a washing machine 10 of the present embodiment 1, (a) is a schematic cross-sectional view of the washing machine 10 observed from the side, (b) is a schematic cross-sectional view of the washing machine 10 observed from the front, and (c) is a schematic view of the interior of the washing machine 10 observed from the top (with the cover 16 removed).
洗衣機10成為在洗衣機箱體即外槽11的內部配置水槽12，在水槽12的內部配置旋轉槽13的構成。水槽12是在洗滌、脫水時貯存水、接受從旋轉槽13排出的水的槽。旋轉槽13是在洗滌時作為洗滌槽發揮功能，在脫水時作為脫水槽發揮功能者，在水槽12的內部可旋轉地設置。 The washing machine 10 is configured such that a water tank 12 is arranged inside an outer tank 11 which is a washing machine housing, and a rotary tank 13 is arranged inside the water tank 12. The water tank 12 is a tank for storing water during washing and dehydration and for receiving water discharged from the rotary tank 13. The rotary tank 13 functions as a washing tank during washing and as a dehydrating tank during dehydration, and is rotatably arranged inside the water tank 12.
在水槽12的上表面，設置有環狀的水槽蓋121。又，在旋轉槽13的上緣部，安裝有用以使旋轉槽13穩定而旋轉的環狀的平衡器14。在洗衣機10的上部，設置有可開關的蓋部16。 An annular tank cover 121 is provided on the upper surface of the tank 12. Also, an annular balancer 14 is installed on the upper edge of the rotating tank 13 to stabilize and rotate the rotating tank 13. An openable cover 16 is provided on the upper portion of the washing machine 10.
在洗衣機10中，若在脫水運轉時等使旋轉槽13旋轉，則根據旋轉槽13內的洗滌物的偏置程度，在旋轉槽13以及水槽12中發生搖動。若此搖動變大，則成為有水槽12碰撞到外槽11的內壁之虞的異常振動。因此，洗衣機10包括偵測如此的異常振動，並在偵測到異常振動的情況停止運轉(停止旋轉槽13的旋轉)的安全裝置。 In the washing machine 10, if the rotary tank 13 is rotated during the dehydration operation, the rotary tank 13 and the water tank 12 will shake depending on the degree of the offset of the laundry in the rotary tank 13. If this shaking becomes larger, it will become an abnormal vibration that may cause the water tank 12 to collide with the inner wall of the outer tank 11. Therefore, the washing machine 10 includes a safety device that detects such abnormal vibration and stops the operation (stops the rotation of the rotary tank 13) when abnormal vibration is detected.
本實施方式1的洗衣機10，作為安全裝置的主要要素在水槽12的外周側面包含測距感測器15。即，洗衣機10的安全裝置是由測距感測器15、及基於測距感測器15的測量值偵測異常振動，在異常振動的偵測時使洗衣機10的運轉停止的控制部(不圖示)而構成。測距感測器15，如圖2所示，其測量方向(圖中箭頭A)朝向水槽12的外周方向。更具體而言，測距感測器15成為設置在與外槽11中的任一內壁對向的位置，測量與在最靠近測距感測器15的位置的內壁111的距離L1。 The washing machine 10 of the present embodiment 1 includes a distance sensor 15 as a main element of the safety device on the outer peripheral side of the water tank 12. That is, the safety device of the washing machine 10 is composed of the distance sensor 15 and a control unit (not shown) that detects abnormal vibration based on the measurement value of the distance sensor 15 and stops the operation of the washing machine 10 when the abnormal vibration is detected. As shown in FIG. 2, the distance sensor 15 has a measurement direction (arrow A in the figure) toward the outer peripheral direction of the water tank 12. More specifically, the distance sensor 15 is set at a position opposite to any inner wall in the outer tank 11, and measures the distance L1 to the inner wall 111 at the position closest to the distance sensor 15.
洗衣機10基於測距感測器15的測量值(測距感測器15與外槽11中的內壁111的距離L1)偵測水槽12的異常振動，在偵測到水槽12的異常振動的情況停止運轉。又，針對基於由測距感測器15測量的距離L1偵測異常振動的具體方法，在本發明中不是特別限定者，在以下例示兩個方法。 The washing machine 10 detects abnormal vibration of the water tank 12 based on the measurement value of the distance sensor 15 (the distance L1 between the distance sensor 15 and the inner wall 111 in the outer tank 11), and stops operating when abnormal vibration of the water tank 12 is detected. In addition, the specific method of detecting abnormal vibration based on the distance L1 measured by the distance sensor 15 is not particularly limited in the present invention, and two methods are exemplified below.
(第一例) (First example)
若在水槽12發生搖動，則測距感測器15的測量值，即距離L1振動。在第一例中，將距離L1與既定的閾值Lth1比較，在距離L1成為比閾值Lth1小的值的情況偵測異常振動。這個情況的閾值Lth1是水槽12成為過於靠近外槽11的內壁111的狀態的距離。在第一例中，由於將測距感測器15的測量值即距離L1直接與閾值Lth1比較，進行判定的控制部的負荷變小。 If the water tank 12 shakes, the distance L1 measured by the distance sensor 15 vibrates. In the first example, the distance L1 is compared with a predetermined threshold value Lth1, and abnormal vibration is detected when the distance L1 becomes a value smaller than the threshold value Lth1. The threshold value Lth1 in this case is the distance at which the water tank 12 becomes too close to the inner wall 111 of the outer tank 11. In the first example, since the distance L1 measured by the distance sensor 15 is directly compared with the threshold value Lth1, the load of the control unit that performs the judgment is reduced.
(第二例) (Second example)
在第二例中，在距離L1被輸入的控制部中，將振動的距離L1的最大值Lmax與最小值Lmin的差分值作為水槽12的振動振幅Lw而進行計算。並且，將已計算的振動振幅Lw與既定的閾值Lth2比較，在振動振福Lw成為比閾值Lth2大的值的情況偵測異常振動。在第二例中，雖然在控制部中計算振動振福Lw的演算處理成為必要，但由於能夠基於從振動中心向兩側的位移進行偵測，偵測精度變高。 In the second example, in the control unit to which the distance L1 is input, the difference between the maximum value Lmax and the minimum value Lmin of the vibration distance L1 is calculated as the vibration amplitude Lw of the water tank 12. Furthermore, the calculated vibration amplitude Lw is compared with a predetermined threshold value Lth2, and abnormal vibration is detected when the vibration amplitude Lw becomes a value larger than the threshold value Lth2. In the second example, although the calculation process of calculating the vibration amplitude Lw in the control unit becomes necessary, the detection accuracy becomes higher because it can be detected based on the displacement from the vibration center to both sides.
又，雖然洗衣機10中的水槽12的搖動主要是因旋轉槽13內的洗滌物的偏置而發生者，但即便在旋轉槽13的旋轉開始有洗滌物的偏置，也有因繼續某種程度旋轉而此偏置被平均而水槽12的搖動變小。因此，在第一例中，不僅在距離L1成為比閾值Lth1小的值的時間點直接偵測異常振動，也可以在距離L1成為比閾值Lth1小的值的狀態被檢測到規定次數以上的情況偵測異常振動。同樣地，在第二例中，也可以在振動振福Lw成為比閾值Lth2大的值的狀態被檢測到規定次數以上的情況偵測異常振動。 Furthermore, although the shaking of the water tank 12 in the washing machine 10 is mainly caused by the offset of the laundry in the rotating tank 13, even if there is an offset of the laundry at the beginning of the rotation of the rotating tank 13, the shaking of the water tank 12 becomes smaller due to the average of the offset as the rotation continues to a certain extent. Therefore, in the first example, not only can the abnormal vibration be directly detected at the time point when the distance L1 becomes a value smaller than the threshold Lth1, but the abnormal vibration can also be detected when the distance L1 becomes a value smaller than the threshold Lth1 and is detected more than a specified number of times. Similarly, in the second example, the abnormal vibration can also be detected when the vibration amplitude Lw becomes a value larger than the threshold Lth2 and is detected more than a specified number of times.
如上述，本實施方式1的洗衣機10是，對水槽12安裝測距感測器15，由測距感測器15測量既定的方向的外槽11的內壁與測距感測器15的距離L1，基於測距感測器15的測量值偵測水槽12的異常振動者。藉由使用以非接觸來測量距離的測距感測器15，在洗衣機10中，也能夠偵測位移小的水槽12的搖動。因此，洗衣機10能夠在水槽12與外槽11的碰撞產生前確實地偵測水槽12的異常振動，防止水槽12與外槽11的碰撞。 As described above, the washing machine 10 of the present embodiment 1 is a washing machine that installs a distance sensor 15 on the water tank 12, and the distance sensor 15 measures the distance L1 between the inner wall of the outer tank 11 in a predetermined direction and the distance sensor 15, and detects abnormal vibrations of the water tank 12 based on the measurement value of the distance sensor 15. By using the distance sensor 15 that measures the distance in a non-contact manner, the washing machine 10 can also detect the shaking of the water tank 12 with a small displacement. Therefore, the washing machine 10 can accurately detect the abnormal vibration of the water tank 12 before the collision between the water tank 12 and the outer tank 11 occurs, and prevent the collision between the water tank 12 and the outer tank 11.
又，以非接觸來測量距離的測距感測器15基本上不是產生與外槽11的接觸者。因此，測距感測器15的安裝位置在洗衣機10的長年使用中沒有變化，能夠維持高的偵測精度。 Furthermore, the distance sensor 15 that measures distance in a non-contact manner basically does not come into contact with the outer tank 11. Therefore, the installation position of the distance sensor 15 does not change during the long-term use of the washing machine 10, and a high detection accuracy can be maintained.
此外，由於測距感測器15的測量方向朝向水槽12的外周方向，測距感測器15是測量與在最靠近的位置的內壁111的距離L1者，被測量的距離L1成為短的距離。在這個情況，對於測距感測器15，能夠使用三角測量型等的便宜的感測器。當然，使用於測距感測器15的感測器的種類不是特別限定者，超音波感測器、雷射感測器等也可使用。 In addition, since the measuring direction of the distance measuring sensor 15 is toward the outer peripheral direction of the water tank 12, the distance measuring sensor 15 measures the distance L1 to the inner wall 111 at the closest position, and the measured distance L1 becomes a short distance. In this case, for the distance measuring sensor 15, an inexpensive sensor such as a triangulation type can be used. Of course, the type of sensor used for the distance measuring sensor 15 is not particularly limited, and ultrasonic sensors, laser sensors, etc. can also be used.
在圖1所示的洗衣機10中，例示了測距感測器15安裝在水槽12的外周側面的構成。然而，在實施方式1的洗衣機10中，測距感測器15的安裝位 置不是限定為此者。例如，測距感測器15，如圖3所示，也可以安裝在水槽12的上表面(即水槽蓋121的上表面)。 In the washing machine 10 shown in FIG. 1 , the distance sensor 15 is illustrated as being mounted on the outer peripheral side of the water tank 12. However, in the washing machine 10 of Embodiment 1, the mounting position of the distance sensor 15 is not limited to this. For example, the distance sensor 15, as shown in FIG. 3 , may also be mounted on the upper surface of the water tank 12 (i.e., the upper surface of the water tank cover 121).
[實施方式2] [Implementation Method 2]
圖4是表示本實施方式2的洗衣機10A的概略構成的圖，是從上表面側觀察洗衣機10A的內部(拆下了蓋部16的狀態)的示意圖。 FIG. 4 is a diagram showing the schematic structure of the washing machine 10A of the second embodiment, and is a schematic diagram of the interior of the washing machine 10A (with the cover 16 removed) viewed from the top surface.
本實施方式2的洗衣機10A對水槽12包括兩個測距感測器15a、15b，測距感測器15a、15b是沿著水槽12的外周方向互相分離90°而安裝。又，測距感測器15a、15b的各個是，與實施方式1的測距感測器15相同，其測量方向朝向水槽12的外周方向。因此，測距感測器15a測量與圖4所示的內壁111的距離，測距感測器15b測量與內壁112的距離。 The washing machine 10A of the second embodiment includes two distance sensors 15a and 15b for the water tank 12. The distance sensors 15a and 15b are installed 90 degrees apart from each other along the outer peripheral direction of the water tank 12. In addition, each of the distance sensors 15a and 15b is the same as the distance sensor 15 of the first embodiment, and its measurement direction is toward the outer peripheral direction of the water tank 12. Therefore, the distance sensor 15a measures the distance to the inner wall 111 shown in Figure 4, and the distance sensor 15b measures the distance to the inner wall 112.
並且，由於測距感測器15a、15b沿著水槽12的外周方向互相分離90°而安裝，兩個測距感測器15a、15b的測量方向在俯視下互相正交。具體而言，測距感測器15a能夠偵測水槽12的左右方向的搖動，測距感測器15b能夠偵測水槽12的前後方向的搖動。 Furthermore, since the distance sensors 15a and 15b are installed 90° apart from each other along the outer circumference of the water tank 12, the measuring directions of the two distance sensors 15a and 15b are orthogonal to each other when viewed from above. Specifically, the distance sensor 15a can detect the shaking of the water tank 12 in the left and right directions, and the distance sensor 15b can detect the shaking of the water tank 12 in the front and back directions.
洗衣機10A成為在以測距感測器15a、15b的任一者偵測到異常振動的情況停止運轉(停止旋轉槽13的旋轉)。 The washing machine 10A stops operating (stops the rotation of the rotary tank 13) when any of the distance sensors 15a and 15b detects abnormal vibration.
如此，在本實施方式2的洗衣機10A中，包括兩個測距感測器15a、15b，設為偵測二方向的搖動的理由是如以下所述。 Thus, in the washing machine 10A of the second embodiment, two distance measuring sensors 15a and 15b are included to detect shaking in two directions for the following reasons.
在脫水運轉時等發生的水槽12的搖動主要是在旋轉槽13內的洗滌物有偏置的情況因旋轉槽13的離心力而產生者。然而，根據安裝在水槽12的驅動部、排水管等的機構的影響、洗衣機10A的設置面的傾斜等，水槽12的搖動不限定為在全方位平均地發生，也有某一方向的搖動比其他方向的搖動大。例如，也有前後方向的搖動比左右方向的搖動大。 The shaking of the water tank 12 during the dehydration operation is mainly caused by the centrifugal force of the rotating tank 13 when the laundry in the rotating tank 13 is offset. However, due to the influence of the mechanism such as the drive unit and the drain pipe installed in the water tank 12, the inclination of the installation surface of the washing machine 10A, etc., the shaking of the water tank 12 is not limited to occur evenly in all directions, and the shaking in one direction may be greater than the shaking in other directions. For example, the shaking in the front-back direction may be greater than the shaking in the left-right direction.
藉由實施方式1的僅一個測距感測器15，在能夠偵測左右方向的搖動的、不能偵測前後方向的搖動而水槽12的搖動在前後方向中大幅度地產生的情況，不能夠適當地停止運轉，也可能發生產生水槽12的異常振動。 In the embodiment 1, only one distance measuring sensor 15 can detect the shaking in the left and right direction but cannot detect the shaking in the front and back direction. If the shaking of the water tank 12 occurs greatly in the front and back direction, the operation cannot be stopped properly, and abnormal vibration of the water tank 12 may occur.
與此相對，本實施方式2的洗衣機10A包括兩個測距感測器15a、15b，在正交的二方向中可進行搖動的偵測。因此，不論水槽12的搖動在哪個方向產生，也能夠偵測其而更確實地防止水槽12的異常振動。 In contrast, the washing machine 10A of the second embodiment includes two distance measuring sensors 15a and 15b, which can detect shaking in two orthogonal directions. Therefore, no matter in which direction the shaking of the water tank 12 occurs, it can be detected and abnormal vibration of the water tank 12 can be prevented more reliably.
又，在本實施方式2的洗衣機10A在正交的二方向中進行搖動的偵測時，也可以僅對一方的方向的搖動偵測使用測距感測器，對其他的方向的搖動偵測，使用在以往的安全裝置使用的機械式的開關桿。在這個情況，對以往設計的洗衣機能夠以加上一個測距感測器對應，洗衣機的設計變更變得容易。這個情況是較佳為在水槽12與外槽11的距離為比較大的方向使用以往的機械式感測器，在水槽12與外槽11的距離為比較小的方向使用具有高的偵測精度的測距感測器。 Furthermore, when the washing machine 10A of the second embodiment detects shaking in two orthogonal directions, a distance sensor may be used only for shaking detection in one direction, and a mechanical switch lever used in a conventional safety device may be used for shaking detection in the other direction. In this case, a distance sensor can be added to the washing machine of the conventional design, and the design change of the washing machine becomes easy. In this case, it is preferable to use the conventional mechanical sensor in the direction where the distance between the water tank 12 and the outer tank 11 is relatively large, and to use a distance sensor with high detection accuracy in the direction where the distance between the water tank 12 and the outer tank 11 is relatively small.
[實施方式3] [Implementation Method 3]
圖5是表示本實施方式3的洗衣機10B的概略構成的圖，是從上表面側觀察洗衣機10B的內部(拆下了蓋部16的狀態)的示意圖。 FIG. 5 is a diagram showing the schematic structure of the washing machine 10B of the third embodiment, and is a schematic diagram of the interior of the washing machine 10B (with the cover 16 removed) viewed from the top surface.
本實施方式3的洗衣機10B在水槽12的上表面(即水槽蓋121的上表面)包含測距感測器15。測距感測器15，如圖5所示，其測量方向(圖中箭頭B)朝向水槽12的內周方向。由此，測距感測器15成為測量從測距感測器15與在最分離的位置的內壁113的距離L2。 The washing machine 10B of the third embodiment includes a distance sensor 15 on the upper surface of the water tank 12 (i.e., the upper surface of the water tank cover 121). As shown in FIG. 5 , the distance sensor 15 has a measurement direction (arrow B in the figure) toward the inner circumference of the water tank 12. Thus, the distance sensor 15 measures the distance L2 between the distance sensor 15 and the inner wall 113 at the most separated position.
雖然由洗衣機10B的測距感測器15測量的距離L2是比實施方式1的距離L1長的距離，但在水槽12與搖動相應而產生位移則與距離L1相同。因此，本實施方式3的洗衣機10B基於由測距感測器15測量的距離L2，藉由與實施方式1相同的原理能夠偵測水槽12的異常振動。 Although the distance L2 measured by the distance sensor 15 of the washing machine 10B is longer than the distance L1 of the first embodiment, the displacement of the water tank 12 in response to the shaking is the same as the distance L1. Therefore, the washing machine 10B of the third embodiment can detect abnormal vibration of the water tank 12 based on the distance L2 measured by the distance sensor 15 by the same principle as the first embodiment.
此外，本實施方式3的洗衣機10B有藉由測距感測器15，也能夠偵測從旋轉槽13的洗滌物的飛出的優點。在一般的洗衣機中，有在洗滌或者脫水運轉的開始時等洗滌物從旋轉槽飛出，已飛出的洗滌物的一部分載置在水槽蓋的上表面。由於如此的洗滌物的飛出不是特別使水槽的搖動增大者，以偵測水槽的搖動的以往的安全裝置則無法偵測。然而，若在洗滌物已從旋轉槽飛出的狀態繼續洗衣機的運轉，則能夠容易地想像會對已飛出的洗滌物產生損傷。因此，在已產生從旋轉槽的洗滌物的飛出的情況，較佳為偵測此並停止運轉。 In addition, the washing machine 10B of the present embodiment 3 has the advantage of being able to detect the laundry flying out of the rotary tank 13 by means of the distance measuring sensor 15. In a general washing machine, laundry may fly out of the rotary tank at the beginning of a washing or dehydration operation, and a portion of the laundry that has flown out may be placed on the upper surface of the water tank cover. Since such laundry flying out does not particularly increase the shaking of the water tank, the previous safety device for detecting the shaking of the water tank cannot detect it. However, if the washing machine is continued to operate in a state where the laundry has already flown out of the rotary tank, it is easy to imagine that the laundry that has flown out may be damaged. Therefore, in the event that flying of laundry from the rotary tank has occurred, it is preferable to detect this and stop the operation.
在本實施方式的洗衣機10B中，測距感測器15的測量方向朝向水槽12的內周方向。因此，如圖6(a)、(c)所示，在已飛出的洗滌物LD在測距感測器15的測量方向側時，測距感測器15測量至洗滌物LD為止的距離，其測量值顯著地變短。由此，洗衣機10B能夠藉由測距感測器15偵測從旋轉槽13的洗滌物的飛出，在已偵測此的情況能夠停止運轉。 In the washing machine 10B of the present embodiment, the measuring direction of the distance sensor 15 is toward the inner circumference direction of the water tank 12. Therefore, as shown in Figures 6(a) and (c), when the laundry LD that has flown out is on the measuring direction side of the distance sensor 15, the distance measured by the distance sensor 15 to the laundry LD becomes significantly shorter. Thus, the washing machine 10B can detect the laundry flying out of the rotary tank 13 by the distance sensor 15, and can stop the operation when this is detected.
又，如圖6(b)、(d)所示，在已飛出的洗滌物LD不在測距感測器15的測量方向側時，在這個時間點無法偵測從旋轉槽13的洗滌物的飛出。但是，在這個情況，已飛出的洗滌物LD也隨著旋轉槽13的旋轉而移動在水槽蓋121的上表面，最終到達圖6(a)、(c)所示的狀態。因此，能夠防止在洗滌物已從旋轉槽13飛出的狀態繼續長時間的運轉。 Furthermore, as shown in FIG. 6(b) and (d), when the laundry LD that has flown out is not on the measuring direction side of the distance sensor 15, the laundry that has flown out of the rotary tank 13 cannot be detected at this time point. However, in this case, the laundry LD that has flown out also moves on the upper surface of the water tank cover 121 as the rotary tank 13 rotates, and finally reaches the state shown in FIG. 6(a) and (c). Therefore, it is possible to prevent the laundry from continuing to operate for a long time in the state where the laundry has flown out of the rotary tank 13.
又，在本實施方式3的洗衣機10B中，測距感測器15配置在水槽蓋121的上表面。在這個情況，測距感測器15，如圖7所示，較佳為由測距感測器15的配置位置的旋轉槽13的旋轉方向(圖中箭頭C)的上游側已傾斜的蓋覆蓋。由此，能夠防止已飛出的洗滌物LD掛在測距感測器15。 In the washing machine 10B of the third embodiment, the distance sensor 15 is arranged on the upper surface of the water tank cover 121. In this case, the distance sensor 15 is preferably covered by a cover tilted upstream of the rotation direction (arrow C in the figure) of the rotating tank 13 at the arrangement position of the distance sensor 15, as shown in FIG. 7. Thus, it is possible to prevent the laundry LD that has flown out from being caught on the distance sensor 15.
在上述實施方式1~3中，雖然例示了將本發明適用在縱型洗衣機或者縱型洗衣烘乾機中的情況，但本發明不是限定為此者，也可適用在滾筒式洗衣機、烘乾機。 In the above embodiments 1 to 3, although the present invention is applied to a vertical washing machine or a vertical washing and drying machine, the present invention is not limited to these and can also be applied to a drum washing machine or drying machine.
本次所揭示的實施方式是以所有的點舉例說明，不是成為限制性的解釋的根據者。因此，本發明的技術範圍不是僅由上述的實施方式來解釋，而是基於申請專利範圍的記載來劃定。又，包含與專利申請範圍均等的意義及範圍內的所有的變更。 The embodiments disclosed this time are all examples and are not the basis for restrictive interpretation. Therefore, the technical scope of the present invention is not interpreted only by the above-mentioned embodiments, but is defined based on the description of the patent application scope. In addition, it includes all changes within the meaning and scope equivalent to the patent application scope.
