[0041] like Figure 1 , Figure 2 and Figure 4As shown, a refrigerator 100 provided in an embodiment of the present application includes a cabinet body 10, a door body 20, a top door mechanism 30 and a plurality of push switch assemblies 40, wherein the door body 20 is slidably connected to the cabinet body 10 for controlling the opening / closing of the cabinet body 10; the top door mechanism 30 is installed on the cabinet body 10, and the top door mechanism 30 can push the top door body 20 so that the door body 20 moves relative to the cabinet body 10 and opens the cabinet body 10; at least two of the plurality of push switch assemblies 40 are arranged on the two side walls 11 of the cabinet body 10 in the horizontal direction, and each push switch assembly 40 can be triggered by the door body 20 and generate a feedback signal, and the feedback signal is used to control the start of the top door mechanism 30. That is, the refrigerator 100 can trigger the push switch assembly 40 by pressing the door body 20 to control the top door mechanism 30 to automatically open the door body 20 from the cabinet body 10. Here, the box body 10 is configured as a freezer liner of the refrigerator 100. Of course, in other embodiments, the box body 10 may also be a refrigerated liner. It should be noted that the structure of the top door mechanism 30 and the working principle of how to control the start of the top door mechanism 30 according to the feedback signal generated after the push switch assembly 40 is triggered can all adopt existing conventional methods, which will not be elaborated here.

[0042] It can be understood that the automatic door opening function of the refrigerator 100 is realized by pressing and triggering at least one press switch assembly 40 by the door body 20, so that the entire door body 20 can be pressed and triggered, that is, the sensing area of ​​the refrigerator 100 to realize the automatic door opening function is large and the sensing is sensitive, which can facilitate the user's operation of automatically opening the refrigerator 100.

[0043] like Figure 2 , Figure 3 As shown, the door body 20 includes a door liner 21, and the door liner 21 and the box body 10 are abutted and sealed by a sealing strip 101; when the door body 20 closes the box body 10, the push switch assembly 40 is in an untriggered state. That is to say, the refrigerator 100 uses the elastic deformation of the sealing strip 101 to provide a moving stroke for the door liner 21 when pressed by the user, so as to meet the use requirement that the push switch assembly 40 can be triggered by the door liner 21. Here, when the door body 20 closes the box body 10, the user can deform the sealing strip 101 after pressing the door liner 21, and press the push switch assembly 40 inward, wherein the deformation stroke of the sealing strip 101 is 4mm. It should be noted that the sealing strip 101 can be assembled to the box body 10 or the door liner 21 according to the use requirements, wherein the specific structure of the sealing strip 101 and how to install it to the box body 10 or the door liner 21 can adopt the conventional method of the existing refrigerator, which will not be elaborated here.

[0044] like Figure 2 , Figure 4 and Figure 5 As shown, a guide rail 22 is installed on the door body 20, and a guide rail bracket 12 is installed in the box body 10. The guide rail 22 is slidably connected to the guide rail bracket 12, thereby realizing the sliding connection between the door body 20 and the box body 10. Here, the number of guide rails 22 is configured to be two, and the two guide rails 22 are arranged on both sides of the door body 20 in the horizontal direction.

[0045] As preferably, Figure 5 As shown, a bracket lining iron 23 is installed on the door body 20, and the bracket lining iron 23 is arranged corresponding to the guide rail 22. A hook (not shown) is formed on the bracket lining iron 23, and the hook can be engaged with the corresponding guide rail 22; wherein, the refrigerator 100 also includes a connector (not shown), and the connector is used to fix the guide rail 22 engaged with the bracket lining iron 23. In other words, the guide rail 22 can be assembled and positioned on the door body 20 by engaging with the hook on the bracket lining iron 23, and then fixed with the connector, so that on the one hand, the accuracy of the assembly position of the guide rail 22 on the door body 20 can be ensured, and on the other hand, the guide rail 22 can be easily assembled on the door body 20. Here, the connector is configured as a screw or a bolt. Of course, the guide rail 22 can also be directly fixed to the door liner 21 of the door body 20 by welding, which will not be elaborated here.

[0046] like Figure 4 As shown, the top door mechanism 30 is installed on the outside of the bottom wall 111 of the box body 10, and the top door mechanism 30 is arranged in the middle position of the box body 10 in the horizontal direction. Of course, the top door mechanism 30 can also be arranged at other positions of the bottom wall 111 of the box body 10, which will not be elaborated here.

[0047] like Figure 4 As shown, the number of push switch assemblies 40 is configured as two, and the two push switch assemblies 40 are symmetrically arranged relative to the box body 10. Of course, in other embodiments, the number of push switch assemblies 40 is also configured as three, four, or even more, and the arrangement positions of the multiple push switch assemblies 40 on the box body 10 can be specifically set according to the use requirements, which will not be elaborated here.

[0048] like Figure 3 As shown, the push switch assembly 40 includes a button 41 and a pressure sensor 42, and the button 41 is movably mounted on the box body 10 to trigger the pressure sensor 42. In other words, the door 21 can trigger the pressure sensor 42 by pressing the button 41, so that the pressure sensor 42 generates a feedback signal.

[0049] As preferably, Figure 3As shown, when the push switch assembly 40 is in an untriggered state, the button 41 and the door liner 21 are in interference fit, that is, the button 41 is in a pre-compressed state before triggering the pressure sensor 42, which can further improve the sensitivity of the pressure sensor 42 when it is triggered by the button 41. Here, the compression stroke of the door liner 21 on the box body 10 when the button 41 is closed is 2 mm.

[0050] like Figure 3 As shown, the push switch assembly 40 further includes an elastic member 43, which is disposed on a side of the button 41 away from the door liner 21, and the elastic member 43 is connected to the button 41 in a pre-compressed manner, so that the push switch assembly 40 can use the elasticity of the elastic member 43 to push the button 41, thereby meeting the use requirement that the button 41 is pressed by the door liner.

Here, the box body 10 protrudes outward and forms a bent convex portion 13. The mounting plate 44 can be detachably mounted to the area where the bent convex portion 13 is located by using connecting members such as screws and bolts, and covers the cavity (not shown) formed inwardly by the bent convex portion 13, so that when the push switch assembly 40 is assembled on the box body 10, on the one hand, it will not occupy the internal space of the box body 10, and on the other hand, it can also protect the button 41, the pressure sensor 42 and the elastic member 43 of the push switch assembly 40.

[0052] like Figure 4 As shown, the button 41 partially extends outward toward the door body 20 relative to the mounting plate 44; wherein, a step surface 411 is formed on the button 41, and the step surface 411 can abut against the mounting plate 44, and is used to limit the button 41 to the mounting plate 44, so that the assembly limit of the button 41 on the mounting plate 44 can be achieved to prevent the button 41 from detaching from the mounting plate 44.

[0053] From the above, it can be seen that the refrigerator 100 of the present application utilizes the triggering of the press switch assembly 40 when the door body 20 is pressed to realize the opening control of the top door mechanism 30, and uses the top door mechanism 30 to realize the automatic opening of the door body 20, which can facilitate the user to operate the automatic opening of the refrigerator 100.

[0054] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
