所述抽屉门2的顶部设有用于抽拉所述抽屉门2的暗把手,所述感应开关3设置于所述
上门1底部。所述感应开关3为遥感无接触式触发的感应开关3,例如光电接收管、红外感应开关3等。以红外感应开关3为例,红外开关的红外线有效感应范围可以在X、Y、Z三个方向的距离进行调节,调节距离的长度依据不同品牌红外开关本身的设计性能或不同型号门体不同距离的实际情况进行调节。本发明对于红外感应开关3参数的设置不做细节阐述。所述感应开关3自其本身向外扩散,方便用户触发所述感应开关3的感应区为有效感应区31;根据感应开关3的有效感应区31所在的位置不同,本发明提供两种实施方式。a top of the drawer door 2 is provided with a dark handle for pulling the drawer door 2, and the sensor switch 3 is disposed at the
The bottom of the door is 1. The inductive switch 3 is a sensing switch 3 for remote sensing contactless triggering, such as a photoelectric receiving tube, an infrared sensing switch 3, and the like. Taking the infrared sensor switch 3 as an example, the infrared effective sensing range of the infrared switch can be adjusted in the distances of X, Y and Z. The length of the adjustment distance is based on the design performance of different brands of infrared switches or the different distances of different models. The actual situation is adjusted. The invention does not elaborate on the setting of the parameters of the infrared sensor switch 3. The sensing switch 3 is outwardly diffused from itself, so that the user can trigger the sensing area of the sensing switch 3 to be the effective sensing area 31. According to the position of the effective sensing area 31 of the sensing switch 3, the present invention provides two embodiments. .
如图3所示,所述有效感应区31位于所述暗把手内。为了避免干扰,所述感应开关3的感应距离和角度根据需要进行调节,例如所述感应开关在Y-Z平面内的感应角度为10°,在Z方向的感应距离为60mm;使得所述有效感应区31域的边界未触及所述暗把手的底部及内侧壁,当触发物被置入所述暗把手内且位于所述有效感应区31内时,即可触发所述感应开关3,同时又不会因暗把手的存在而产生误动作。As shown in FIG. 3, the effective sensing area 31 is located in the dark handle. In order to avoid interference, the sensing distance and angle of the inductive switch 3 are adjusted as needed, for example, the sensing angle of the inductive switch in the YZ plane is 10°, and the sensing distance in the Z direction is 60 mm; The boundary of the 31 field does not touch the bottom and the inner side wall of the dark handle. When the trigger is placed in the dark handle and is located in the effective sensing area 31, the sensing switch 3 can be triggered without It will cause a malfunction due to the presence of the dark handle.
在所述抽屉门2关闭状态下,当触发物被置入暗把手内发出触发信号时,所述感应开关3被触发,从而所述感应开关3启动所述驱动***使所述抽屉门2体自动打开。所述触发物通常为用户的手,当然,所述触发物也可以为用户手持的其他物品。In the closed state of the drawer door 2, when the trigger is placed in the dark handle to issue a trigger signal, the sensor switch 3 is triggered, so that the sensor switch 3 activates the drive system to make the drawer door 2 body automatically open. The trigger is usually the user's hand. Of course, the trigger can also be other items held by the user.
按照使用***常落入的脏水等杂物不会沾污所述感应开关3,同时用户手伸入到暗把手内时手上的油污等也不会沾污所述感应开关3,从而能够使得所述感应开关3长久保持清洁和较高的感应灵敏度。According to the usage habit, when the drawer door 2 needs to be opened, the user naturally inserts the hand into the dark handle of the corresponding drawer door 2, and the sensor switch 3 can receive the trigger signal of the hand, and activate the drive system to drive the drawer door 2 It is automatically opened; it does not affect the user's usage habits, and it is also convenient for users in the home to use without knowing. In addition, the dirty water and the like which are usually dropped in the dark handle do not contaminate the inductive switch 3, and the oil or the like on the hand does not contaminate the inductive switch 3 when the user's hand reaches into the dark handle. Thereby, the inductive switch 3 can be kept clean and high in sensitivity for a long time.
进一步地,所述冰箱100还包括设置于所述上门1底部且与所述感应开关3通信连接的提示器4,当所述感应开关3感应到触发信号时,启动所述提示器4使其以振动、发声、发光灯方式发出提示,告知用户所述感应开关3已启动,便于用户让出所述抽屉门2打开的空间。Further, the refrigerator 100 further includes a prompter 4 disposed at the bottom of the upper door 1 and communicably connected to the inductive switch 3. when the inductive switch 3 senses a trigger signal, the prompter 4 is activated to be A prompt is issued in the form of vibration, sounding, and illuminating light to inform the user that the sensing switch 3 has been activated, so that the user can let out the space in which the drawer door 2 is opened.
本实施例中,所述提示器4为照明灯4,且所述照明灯4位于所述上门1的底部;一方面可以给出所述感应开关3启动的提示,另一方面可以给所述抽屉内提供照明,方便用户取用物品。In this embodiment, the prompting device 4 is an illumination lamp 4, and the illumination lamp 4 is located at the bottom of the upper door 1; on the one hand, a prompt for starting the induction switch 3 can be given, and on the other hand, the illumination lamp can be given Lighting is provided in the drawer for easy access by the user.
所述感应开关3和所述照明灯4设置于所述下门2的底部,其具体结构不限,只要所述暗把手落入所述感应开关3的有效感应区31内,且所述照明灯4能够照亮所述抽屉内即可。The inductive switch 3 and the illumination lamp 4 are disposed at the bottom of the lower door 2, and the specific structure thereof is not limited as long as the dark handle falls into the effective sensing area 31 of the inductive switch 3, and the illumination The lamp 4 can illuminate the inside of the drawer.
如图1~5所示,所述上门1具有位于顶部的上饰条14、内衬15、位于底部的下饰条16、前面板17,所述感应开关3和所述照明灯4设置于所述下饰条16上。具体地,所述冰箱100具有沿所述上门1宽度方向也即X方向间隔设置的若干感应开关3、若干照明灯4,所述照明灯4与所述感应开关3沿所述上门1宽度方向交错设置,分布均匀。每一个所述感应开关3均为大角度辐射,辐射角度可以为60°或更大的角度,无具体限定;在X-Z平面内,相

The illumination lamp 4 and the inductive switch 3 are along the width direction of the upper door 1 . Interlaced settings, evenly distributed. Each of the inductive switches 3 is a large-angle radiation, and the radiation angle may be an angle of 60° or more, which is not specifically limited; in the X-Z plane, the phase
An effective sensing area 31 adjacent to the inductive switch 3 is seamlessly connected, and a total effective sensing area 31 of the plurality of inductive switches 3 can be seamlessly connected in the width direction of the drawer door 2 to avoid being in the effective sensing area 31. Inductive blind spots appear within.
本领域技术人员可以理解的是,所谓“无缝连接”指的是,触发物例如手放入有效感应区31的任意位置处,均可以被所述感应开关3检测到;包括以下几种情况:相邻的所述感应开关3的有效感应区31存在部分重叠;或相邻的所述感应开关3的有效感应区31边缘恰好紧挨着;或者相邻的所述感应开关3的有效感应区31之间存在很小的间隙,但该间隙比一般触发物均小,从而当触发物位于该间隙处时有部分触发物位于该间隙一侧或两侧的有效感应区31内以触发相应的所述感应开关3。It can be understood by those skilled in the art that the so-called "seamless connection" means that a trigger, such as a hand, is placed at any position of the effective sensing area 31, and can be detected by the inductive switch 3; The adjacent active sensing area 31 of the inductive switch 3 has a partial overlap; or the edge of the effective sensing area 31 of the adjacent inductive switch 3 is just next to each other; or the effective sensing of the adjacent inductive switch 3 There is a small gap between the regions 31, but the gap is smaller than the general trigger, so that when the trigger is located at the gap, a part of the trigger is located in the effective sensing area 31 on one side or both sides of the gap to trigger the corresponding The inductive switch 3.
根据所述感应开关3的数量和安装位置,总的有效感应区31可以覆盖所述暗把手内的中间部分区域或者覆盖所述暗把手的全部区域。从而用户将手放入所述暗把手内的有效感应区31的任意位置时均能触发所述感应开关3。若干照明灯的辐射角度也部分交叉重叠,所述抽屉内全部位置处均能被照亮无亮光盲区存在。Depending on the number of inductive switches 3 and the mounting position, the total effective sensing area 31 may cover or cover the entire area of the inner portion of the dark handle. Thus, the user can trigger the inductive switch 3 when the user places his hand in any position of the effective sensing area 31 in the dark handle. The radiation angles of several illumination lamps also partially overlap, and all the positions in the drawer can be illuminated without the bright blind zone.

The inductive switch 3 is mounted in the mounting box 161, and is radiated downward through the through hole 163 so that the dark handle is located in the effective sensing area 31 thereof, and the protective cover 164 protects it but does not affect the sensing effect thereof. . The illuminating lamp 4 is mounted in the mounting box 161, and provides light to the opened drawer through the through hole 163, and the protective cover 164 protects it but does not affect the distribution of light.
