TECHNICAL FIELD
[0001] The present application relates to the technical field of refrigerators, in particular to a refrigerator. BACKGROUND
[0002] The refrigerator is one of the indispensable important electrical appliances in modern families, which can prolong the preservation time of food through effective refrigeration function, greatly facilitating people's life. With the progress of science and technology and the improvement of consumer demand, people have put forward higher and higher requirements for the performance and intelligentization of the refrigerator. As one of the key components to realize the intelligent control of the refrigerator, the detection device of the opening and closing state of the refrigerator door is particularly important in practical application. Accurate and reliable detection of the opening and closing state of the refrigerator door is the basis for the normal work of the intelligent control system of the refrigerator. At present, the magnetic spring sensor assembly as a magnetic control switch is the most widely used refrigerator door opening and closing detection device. Its basic working principle is to install a permanent magnet on the refrigerator door and a magnetic sensitive element such as a reed switch on the refrigerator body matched with the door, and to judge the opening and closing state of the refrigerator door by detecting the on-off state of the magnetic sensitive element. The common magnetic spring sensor assembly mainly includes a reed switch (also known as a dry reed or reed tube). The reed switch usually encapsulates two ferromagnetic reeds inside, which are attracted together to conduct the circuit when subjected to the magnetic field force; when the magnetic field disappears, the two reeds are separated to disconnect the circuit under the action of elastic force. Due to the mechanical properties of the reed, this switch can realize non-contact switch control and has a long service life. However, the traditional reed switch is mostly packaged with glass and other relatively fragile materials, which may be damaged due to a large impact or extrusion during the assembly, transportation and handling of the refrigerator, resulting in the failure of the reed switch and affecting the normal use of the refrigerator.
[0003] Therefore, there is still a practical need to continue to improve the structure of the magnetic spring sensor assembly of the refrigerator. CONTENT OF THE INVENTION

Figure 2 The top view of the refrigerator 1000 can be used to exemplify the positional relationship of components such as the refrigerator body 1100, the refrigerator door 1200, the hinge cover 10 and the front cover plate 20.
[0046] Figure 3 Shown Figure 2 The hinged cover 10 of the refrigerator 1000 is shown based on Figure 2 Bottom view from the orientation shown. Figure 3 And the following views are basically based on Figure 2 The left hinged cover 10 is shown as an example, but it should be understood that the right hinged cover 10 is also applicable. Here, in order to monitor the opening and closing of the refrigerator door 1200, the refrigerator 1000 has a reed sensor assembly 1300 provided on the refrigerator body 1100. The reed sensor assembly 1300 includes a cover body 900, which is connected to the refrigerator body 1100 and is preferably made of PP plastic. Figure 3 In the illustrated embodiment, the cover body 900 is configured as the hinged cover 10 of the refrigerator 1000. In other embodiments, the cover body 900 may also be configured as other components of the refrigerator 1000 or as a separate component independent of the refrigerator 1000 itself.
[0047] Figure 4 Shown Figure 3 A schematic exploded view of a reed sensor assembly 1300 is shown; Figure 5 Shown Figure 4 A schematic perspective view of the reed sensor assembly 1300 with the printed circuit board 800 and the reed switch 700 separated; Figure 6 Shown Figure 4 A perspective view of the printed circuit board 800 and the reed switch 700 of the reed sensor assembly 1300 as viewed from another side is shown; Figure 7 Shown along Figure 6 A schematic three-dimensional cross-sectional view taken along the cutting line AA.
[0048] from Figure 4 It can be seen that the cover body 900 of the reed sensor assembly 1300 has a receiving portion 910. The reed sensor assembly 1300 also includes a printed circuit board 800 received in the receiving portion 910 and a reed switch 700 connected to the printed circuit board 800. The reed switch 700 is mounted on the side of the printed circuit board 800 facing the receiving portion 910. Therefore, the printed circuit board 800 and the reed switch 700 are connected to each other. Figure 4 The side shown is mounted toward the receiving portion 910, i.e., with its Figure 6The side shown faces away from the receiving portion 910. Here, the reed switch 700 is preferably fixedly connected to the printed circuit board 800 by surface mount technology (Surface Mount Technology).
[0049] like Figure 4 As shown, the cover body 900 has a protruding structure 920 that limits the receiving portion 910. The protruding structure 920 is Figure 3 In the embodiment shown, the protrusion structure 920 protrudes from the bottom surface of the hinged cover 10 as the cover body 900. Such a protrusion structure 920 is preferably formed integrally on the cover body 900. Figure 3 and Figure 4 Combine Figure 2 It can be seen that the receiving portion 910 is located at the cover body 900 (here exemplified as the hinged cover 10) near the refrigerator door 1200 (refer to FIG. Figure 1 and Figure 2 The left refrigerator door 1200 is located in the area away from the hinge assembly corresponding to the left refrigerator door 1200, so that the reed sensor assembly 1300 (especially its reed switch 700) can more easily detect the opening and closing of the refrigerator door 1200. Even if the refrigerator door 1200 is only opened a small gap, the reed sensor assembly 1300 (especially its reed switch 700) can still keenly capture it due to the position of the reed sensor assembly 1300 (especially its reed switch 700). Figure 3 Combine Figure 2 It can also be seen that the hinged cover 10 has a cover wall 11 close to the side of the refrigerator door 1200, and at least a portion of the cover wall 11 is preferably as shown in FIG. Figure 4 As shown, the convex structure 920 and the accommodating portion 910 are jointly limited. Here, in order to hold the printed circuit board 800 in the accommodating portion 910, the convex structure 920 and the printed circuit board 800 form a snap fit. Specifically, as shown Figure 4 As shown in the example, the printed circuit board 800 has a first side area 810 and a second side area 820 opposite to each other in its longitudinal direction, the first side area 810 has a first protrusion 811, the second side area 820 has a second protrusion 821, and the protrusion structure 920 has corresponding first recesses 100 and second recesses 200. In order to achieve assembly, the printed circuit board 800 is snapped into the first recess 100 with its first protrusion 811 and into the second recess 200 with its second protrusion 821.
[0050] from Figure 4 It can be seen that the printed circuit board 800 has a first anti-fouling portion 801 (eg, an angle with a certain slope), and the protruding structure 920 has a second anti-fouling portion 921 (eg, a corresponding angle with the same slope) that cooperates with the first anti-fouling portion 801 .
[0051] from Figure 4It can also be seen that the printed circuit board 800 has a third side edge region 830 and a fourth side edge region 840 opposite to each other in the lateral direction of the printed circuit board 800, wherein the third side edge region 830 has a port 831 for forming an electrical connection with an external connection terminal, which is preferably implemented detachably. Figure 4 It can also be seen that the printed circuit board 800 has a third side edge region 830 and a fourth side edge region 840 opposite to each other in the lateral direction of the printed circuit board 800, wherein the third side edge region 830 has a port 831 for forming an electrical connection with an external connection terminal, which is preferably implemented detachably. Figure 5 It can also be seen that the printed circuit board 800 has a third side edge region 830 and a fourth side edge region 840 opposite to each other in the lateral direction of the printed circuit board 800, wherein the third side edge region 830 has a port 831 for forming an electrical connection with an external connection terminal, which is preferably implemented detachably. Figure 6 and Figure 7 It can also be seen that the printed circuit board 800 has a third side edge region 830 and a fourth side edge region 840 opposite to each other in the lateral direction of the printed circuit board 800, wherein the third side edge region 830 has a port 831 for forming an electrical connection with an external connection terminal, which is preferably implemented detachably.
[0052] Figure 6 It can also be seen that the printed circuit board 800 has a third side edge region 830 and a fourth side edge region 840 opposite to each other in the lateral direction of the printed circuit board 800, wherein the third side edge region 830 has a port 831 for forming an electrical connection with an external connection terminal, which is preferably implemented detachably.
[0053] Figure 8 It can also be seen that the printed circuit board 800 has a third side edge region 830 and a fourth side edge region 840 opposite to each other in the lateral direction of the printed circuit board 800, wherein the third side edge region 830 has a port 831 for forming an electrical connection with an external connection terminal, which is preferably implemented detachably. Figure 6 Figure 8 In the shown embodiment, the magnetic reed sensor assembly 1300 comprises two reed switches 700 which are connected to the same printed circuit board 800. The two reed switches 700 are used to detect the opening and closing of the same refrigerator door 1200. For example, when the refrigerator door 1200 is opened, the reed switches 700 are both open, i.e. the reed switches 700 are not in contact with each other. When the refrigerator door 1200 is closed, the reed switches 700 are both closed, i.e. the reed switches 700 are in contact with each other. The two reed switches 700 each output a signal which controls a corresponding circuit such that the two circuits are connected in series. Only when both reed switches 700 are closed, the circuit is closed and the refrigerator 1000 can be operated, for example, the ice maker can be operated. Thus, even if one of the reed switches 700 is faulty, for example, the refrigerator door 1200 is not closed, the control system of the refrigerator 1000 can still avoid the ice maker being operated by the other reed switch 700.

Figure 10 A perspective view of the magnetic reed sensor assembly 1300 is shown in Figure 9 another different viewing direction. Figure 11 A perspective view of the magnetic reed sensor assembly 1300 is shown in Figure 9 another different viewing direction.
[0055] As shown in Figure 9 , Figure 10 and Figure 11 , the protrusion 920 comprises a movable portion 400 which can be moved to a certain extent and then returned to its original position during the installation of the printed circuit board 800 carrying the reed switches 700 into the housing 910, thereby allowing the first protrusion 811 of the printed circuit board 800 to be inserted into the first recess 100 and / or the second protrusion 821 of the printed circuit board 800 to be inserted into the second recess 200. The movable portion 400 is preferably configured as an elastically deformable member and is shown as being separated from the rest of the protrusion 920 on both sides thereof to achieve a self-recoverable slight elastic deformation. Thus, the rest of the protrusion 920 can be configured as a rigid member. As can be seen from Figure 11 , the second recess 200 is provided on the movable portion 400. In combination with Figure 10 , the movable portion 400 has a slope 401 for guiding the printed circuit board 800 carrying the reed switches 700 during the installation of the printed circuit board 800 into the housing 910. As shown in Figure 9 and Figure 10 , in order to support the movable portion 400, the protrusion 920 preferably further comprises a corner piece 500.
[0056] FromFigure 9 It can be seen that the protruding structure 920 comprises a support portion 600 for supporting the printed circuit board 800 on the side of the printed circuit board 800 facing the accommodation portion 910, i.e. the side of the printed circuit board 800 and the reed switch 700 facing the refrigerator body 1100 (as shown in the figure). Figure 4 In particular, the support portion 600 can comprise at least one first support member 601 (such as the two spaced-apart first support members 601 shown by way of example) for supporting the first side edge region 810 of the printed circuit board 800; the support portion 600 can comprise at least one second support member 602 for supporting the second side edge region 820 of the printed circuit board 800; the support portion 600 can comprise at least one third support member 603 for supporting the third side edge region 830 of the printed circuit board 800; and the support portion 600 can further comprise at least one fourth support member 604 for supporting the fourth side edge region 840. These first, second, third and fourth support members 601, 602, 603 and 604 preferably have the same support height (in the height direction y in the figure). Figure 9

Figure 1 A schematic exploded view of the cover body 900 of the magnetic reed sensor assembly 1300 is shown as a front cover plate 20 of a refrigerator 1000.
[0058] As shown by way of example, the side of the front cover plate 20 of the refrigerator 1000 facing the refrigerator body 1100 (i.e. the side facing away from the refrigerator door 1200) has two accommodation portions 910 (corresponding to the two refrigerator doors 1200 shown by way of example). Figure 12 As shown by way of example, the side of the front cover plate 20 of the refrigerator 1000 facing the refrigerator body 1100 (i.e. the side facing away from the refrigerator door 1200) has two accommodation portions 910 (corresponding to the two refrigerator doors 1200 shown by way of example). Figure 1 In this case, the printed circuit board 800 and the reed switch 700 thereon are accommodated in each accommodation portion 910, wherein the reed switch 700 is mounted on the side of the printed circuit board 800 facing the accommodation portion 910.
