Description 说明

IMPROVED SPRAY MEANS FOR USE IN A DISHWASHER
用于洗碗机的改进型喷淋装置

[0001] The present invention relates to a dishwasher. The present invention more particularly relates to the spray means of the dishwasher.
[0001] 本发明涉及一种洗碗机。本发明尤其涉及洗碗机的喷淋装置。

[0002] Dishwashers are commonly known in the art. A dishwasher generally comprises: a tub for receiving the articles to be cleaned; a heater for heating the washing liquid; a control unit for controlling the heater; and one or more spray means for spraying the washing liquid onto the articles. The control unit generally comprises one or more washing modes. The spray means comprises one or more nozzles for ejecting the washing liquid into the tub. In the prior art dishwasher during the washing modes the nozzles of the spray means ejects the washing liquid respectively into the tub, and thereby onto the various articles inside the tub.
[0002] 洗碗机在本领域中是众所周知的。洗碗机一般包括：一个用于接收待清洗物品的盆子；一个用于加热洗涤液的加热器；一个用于控制加热器的控制单元；以及一个或多个用于将洗涤液喷洒到物品上的喷洒装置。控制装置一般包括一个或多个清洗模式。喷射装置包括一个或多个喷嘴，用于将洗涤液喷射到盆中。在现有技术的洗碗机中，在洗涤模式期间，喷淋装置的喷嘴分别将洗涤液喷射到浴缸中，从而喷射到浴缸中的各种物品上。

[0003] EP2237716 (A1) discloses a prior art dishwasher.
[0003] EP2237716 (A1) 公开了一种现有技术的洗碗机。

[0004] A problem with the prior art dishwasher is that the washing liquid which is ejected from the nozzles of the spray means impinges onto the same surface areas of the articles throughout the washing modes, and thus at least some surface areas of the articles do not directly receive the washing liquid from the nozzles. Therefore, the articles cannot be uniformly cleaned. Moreover, there is a risk that at least some surface areas of the articles are insufficiently cleaned. In such instances the consumer satisfaction decreases.
[0004] 现有技术的洗碗机存在的一个问题是，从喷射装置的喷嘴喷出的洗涤液在整个洗涤模式中都会撞击到物品的相同表面区域，因此物品的至少某些表面区域无法直接从喷嘴接受洗涤液。因此，物品无法得到均匀清洗。此外，物品的至少某些表面区域有可能未得到充分清洁。在这种情况下，消费者的满意度就会下降。

[0005] An objective of the present invention is to provide a spray means for use in a dishwasher that solves the aforementioned problems of the prior art in a cost effective way and which has an improved cleaning performance.
[0005] 本发明的目的是提供一种用于洗碗机的喷淋装置，该装置能以经济有效的方式解决现有技术中存在的上述问题，并具有更好的清洁性能。

[0006] This objective has been achieved by the spray means as defined in claim 1, and the dishwasher as defined in claim 12. Further achievements have been attained by the subject-matters respectively defined in the dependent claims.
[0006] 权利要求 1 所定义的喷雾装置和权利要求 12 所定义的洗碗机实现了这一目标。从属权利要求中分别定义的主题实现了进一步的成就。

[0007] The spray means of the present invention comprises one or more shape-memory alloys which are adapted to change the shape of the spray means in accordance with the temperature of the washing liquid.
[0007] 本发明的喷洒装置包括一种或多种形状记忆合金，这些形状记忆合金可根据洗涤液的温度改变喷洒装置的形状。

[0008] A major advantageous effect of the present invention is that the surface
[0008] 本发明的一大优势在于，表面
area of the articles inside the tub can be more effectively cleaned through the spray means which changes its shape in accordance with the temperature of the washing liquid.
喷淋装置可根据洗涤液的温度改变形状，从而更有效地清洁浴缸内的物品区域。

[0009] In alternative embodiments, the shape memory alloys are used to form the nozzles and/or the body of the spray means that supports the nozzles. Thereby, the position of the nozzles and/or the ejection direction of the nozzles can be changed, for instance, even to an extent that the rotation direction of the spray means reverses when the shape memory alloys change their shape in accordance with the temperature of the washing liquid. These embodiments are particularly advantageous as the surface area of the articles which directly receives the washing liquid can be increased while the shape of the spray means gradually changes, and thus the cleaning performance can be improved.
[0009] 在其他实施例中，形状记忆合金用于形成喷嘴和/或支撑喷嘴的喷射装置主体。因此，喷嘴的位置和/或喷嘴的喷射方向可以改变，例如，当形状记忆合金根据洗涤液的温度改变其形状时，喷射装置的旋转方向甚至可以反转。这些实施方式特别有利，因为在喷射装置的形状逐渐改变的同时，可增加直接接受洗涤液的物品的表面积，从而提高清洁性能。

[0010] In other alternative embodiments, the shape memory alloys used in the spray means have a two-way shape memory and/or a one-way shape memory.
[0010] 在其他替代实施例中，喷射装置中使用的形状记忆合金具有双向形状记忆和/或单向形状记忆。

[0035] In another embodiment, one or more first nozzles (2a) and/or one or more second nozzles (2b) each comprises one or more shape-memory alloys (3) which are adapted to respectively change the shape of the first nozzles (2a) and/or the second nozzles (2b) in accordance with the temperature of the washing liquid, and thereby the ejection direction of the first nozzles (2a) and/or the second nozzles (2b) respectively (Fig. 3 to Fig. 8).
[0035] 在另一个实施例中，一个或多个第一喷嘴 (2a) 和/或一个或多个第二喷嘴 (2b) 分别包括一个或多个形状记忆合金 (3)，这些形状记忆合金可根据洗涤液的温度分别改变第一喷嘴 (2a) 和/或第二喷嘴 (2b) 的形状，从而分别改变第一喷嘴 (2a) 和/或第二喷嘴 (2b) 的喷射方向（图 3 至图 8）。

[0036] In other alternative embodiments, the first nozzles (2a) eject in the first shape of their shape-memory alloys (3) the washing liquid in a first direction (A) which has a component in the anticlockwise direction or the clockwise direction (Fig. 3). In this embodiment, the first nozzles (2a) eject in the second shape of the shape-memory alloys (3) the washing liquid in a second direction (B) which has a component in the clockwise direction or the anticlockwise direction respectively (Fig. 4). This embodiment is particularly advantageous as the rotating spray arms (5) change the direction of rotation as the shape-memory alloy (3) transits between the martensite phase and the austenite phase. Thereby the rear surface as well as the front surface of the articles can directly receive the washing liquid during the various washing modes. Thereby, the cleaning performance can be improved.
[0036] 在其他替代实施例中，第一喷嘴（2a）以其形状记忆合金（3）的第一形状沿第一方向（A）喷射洗涤液，该方向具有逆时针方向或顺时针方向的分量（图 3）。在本实施例中，第一喷嘴 (2a) 在形状记忆合金 (3) 的第二形状中沿第二方向 (B) 喷射洗涤液，第二方向 (B) 的分量分别为顺时针方向或逆时针方向（图 4）。本实施例特别有利，因为当形状记忆合金 (3) 在马氏体相和奥氏体相之间转换时，旋转喷臂 (5) 会改变旋转方向。因此，在各种清洗模式下，物品的后表面和前表面都能直接接受清洗液。因此，清洗性能可以得到改善。

[0037] In another embodiment, one or more second nozzles (2b) eject in the first shape of their shape-memory alloys (3) the washing liquid in a third direction (C) (Fig. 5). In this embodiment, one or more second nozzles (2b) eject in the second shape of their shape-memory alloy (3) the washing liquid in a fourth direction (D) which is different than the third direction (C), wherein the fourth direction (D) has a radial component (Fig. 6).

[0038] In another embodiment, one or more first nozzles (2a) eject in the first shape of their shape-memory alloys (3) the washing liquid in a fifth direction (E) which points directly towards the bottom section of the tub (Fig. 7). In this embodiment, one or more first nozzles (2a) eject, in the second shape of their shape-memory alloy (3) the washing liquid in a sixth direction (F) which points directly towards the side section of the tub (Fig. 8). This embodiment is particularly advantageous as the washing liquid can be prevented from directly impinging onto the side section of the tub when the shape memory alloys (3) of the first nozzles (2a) are in the first shape, and thus the noise level can be reduced, and the energy efficiency can be improved. Moreover the washing liquid cleans the side section of the tub when the shape memory alloys (3) of the first nozzles (2a) are in the second shape.
