[0035] The appearance requirement of embedded products is very strict, and the gap between each side of the box and the cabinet is required to be smaller. For the occasion prone to falling, such as earthquake-prone areas, the product needs to be connected with the wall or cabinet of the user's home to reduce the possibility of product falling. The existing anti-falling technology includes adding two hanging ears behind the box, and fixing the two hanging ears on the wall by screws. If the product is connected with the cabinet, the structure of the cabinet will be damaged, and it is not convenient to move the product later, which is unacceptable to the user. And in the embedded product, the gap between the box of the product and the cabinet is very small, and there is not enough space to install the fixing screw, that is, the existing anti-falling device cannot be installed in the small gap space.

[0036] To solve the above problems, the present application provides an anti-falling device for household appliances.

[0037] Please refer to Figure 2 , the household appliance includes a box body 21 provided with a box door, in the embodiment, the anti-falling device 10 includes a hook assembly 100 and a latch assembly 200. Wherein, the hook assembly 100 includes a hook 110, the hook 110 is arranged adjacent to the box body 21, the latch assembly 200 includes a latch 210 provided on the box body 21, a flexible piece 220 and a guide piece 400, one end of the flexible piece 220 is connected to the latch 210, the other end is wound on the guide piece 400, and is located on the side of the box body 21 close to the box door, the flexible piece 220 changes the movement direction through the guide piece 400, and is used to control the latch 210 to penetrate or separate from the hook 110.

[0038] After the installation of the household appliance, the box 21 is usually leaned against a stop wall 30 to keep the household appliance stable, the hook 110 is arranged adjacent to the box 21, when the hook 110 is arranged on the stop wall 30 against which the box 21 is leaned, and the bolt 210 is inserted into the hook 110, the bolt 210 is limited in the vertical direction of the insertion of the hook 110. For example, the bolt 210 is arranged horizontally or vertically on the box 21, the side of the box 21 against which the stop wall 30 is leaned is the back, when the box 21 is leaned forward, the hook 110 stops the forward movement of the bolt 210, and the bolt 210 is arranged on the box 21, that is, the hook 110 blocks the forward leaning of the box 21, and the box 21 is connected to the stop wall 30 through the bolt 210 and the hook 110, and plays a role of preventing leaning. After the bolt 210 is separated from the hook 110, the limitation of the hook 110 to the bolt 210 is released, that is, the limitation to the box 21 is released, and the box 21 can be moved freely. By controlling the insertion or separation of the bolt 210 into or from the hook 110, the flexible switching between the two states of preventing leaning and locking of the box 21 and the free movement is realized, and different use requirements are met. The stop wall 30 can be a wall of a wall body, or a cabinet wall of a cabinet; the object for fixing the hook 110 includes but is not limited to other fixed wall surfaces similar to the stop wall 30.

[0039] The bolt 210 is controlled to be inserted into or separated from the hook 110 through the flexible member 220, one end of the flexible member 220 is connected to the bolt 210, and the other end is arranged on the side of the box 21 away from the stop wall 30 after being arranged on the guide member 400; after the installation of the box 21, it is obvious that the side provided with the box door is placed outward, that is, the side close to the box door is closer to the user, when the insertion or separation of the bolt 210 into or from the hook 110 is controlled, it is not necessary to stretch into the area close to the hook 110 for operation, only the operation on the side of the flexible member 220 away from the hook 110 on the box 21 is needed, that is, only standing in front of the box door is needed. Therefore, the installation space required for placing the household appliance does not need to reserve the operation space of the anti-tilting device 10, and in the case that the gap between the household appliance and the installation space is small, the convenient installation and operation of the user on the anti-tilting device 10 can also be realized.

[0040] Specifically, the latch 210 can be arranged horizontally or vertically on the box body 21. When the latch 210 is arranged vertically, it can be arranged on the side wall of the box body 21, and the flexible member 220 controls the vertical reciprocating movement of the latch 210, so as to realize the penetration or disengagement of the latch 210 from the hook 110. When the latch 210 is arranged horizontally, it can be arranged on the top wall of the box body 21, and the flexible member 220 controls the horizontal reciprocating movement of the latch 210, so as to realize the penetration or disengagement of the latch 210 from the hook 110. Considering that when the latch 210 is arranged vertically on the side wall of the box body 21, the direction of the gravity of the latch 210 is the same as the direction of the movement of the latch 210, the latch 210 needs to overcome the influence of gravity whether it is in a fixed state or a moving state, which increases the difficulty of fixing and moving the latch 210. Therefore, preferably, the latch 210 is arranged horizontally on the top wall of the box body 21, and the support of the box body 21 on the latch 210 weakens the influence of gravity on the latch 210, facilitating the fixation and movement of the latch 210.

[0041] Please refer to Figures 2 to 4 In an embodiment, the anti-toppling device 10 further comprises a first support 300 mounted on the top wall of the box body 21, the first support 300 comprising oppositely arranged first and second support portions 310 and 320, the first support portion 310 being provided with a first through hole 311, and the second support portion 320 being provided with a second through hole 321, the latch 210 being arranged horizontally on the first support 300 through the first and second through holes 311 and 321 when penetrating the hook 110.

[0042] The first support 300 fixes and supports the latch 210, and the first and second support portions 310 and 320 can be arranged on the two sides of the hook 110, respectively. When the latch 210 penetrates the first and second through holes 311 and 321, it also penetrates the hook 110, and the first and second support portions 310 and 320 jointly fix and support the latch 210, so that the latch 210 remains inserted into the hook 110. When the latch 210 disengages from the hook 110, the second support portion 320 and the first support portion 310 are arranged left and right, respectively. Taking the right end of the flexible member 220 connected to the latch 210 as an example, the latch 210 moves to the right end under the traction of the flexible member 220, and the latch 210 sequentially disengages from the second through hole 321 and the hook 110, so that the box body 21 is in a free moving state. The first support portion 310 alone fixes and supports the latch 210, so that the latch 210 remains disengaged from the hook 110.

[0043] The first support part 310 and the second support part 320 can also be arranged on the same side of the hook 110, with the second support part 320 and the first support part 310 arranged left and right, and both arranged on the right side of the hook 110. When the pin 210 is inserted into the hook 110, it also passes through the first through hole 311 and the second through hole 321. The first support part 310 and the second support part 320 jointly fix and support the pin 210, so that the pin 210 remains inserted into the hook 110. When the pin 210 is separated from the hook 110, the right end of the pin 210 is connected to the flexible member 220. The pin 210 is pulled by the flexible member 220 and moves to the right end. The pin 210 is separated from the hook 110 and still passes through the first through hole 311 and the second through hole 321. The first support part 310 and the second support part 320 jointly fix and support the pin 210, so that the pin 210 remains separated from the hook 110. Compared with the first support part 310 alone supporting the pin 210 to keep the pin 210 separated from the hook 110, the first support part 310 and the second support part 320 jointly supporting the pin 210 can make the pin 210 more stably keep separated from the hook 110. During the process of the pin 210 being reset and inserted into the hook 110, the moving direction of the pin 210 can be maintained to ensure that the pin 210 is aligned with the hook 110 for insertion.

[0044] Please refer to Figure 3 and Figure 4 Further, in an embodiment, the anti-toppling device 10 further comprises a second support 500 mounted on the top wall of the box 21 and located on the side of the second support part 320 away from the first support part 310. The second support 500 comprises a third support part 510 and a fourth support part 520 arranged opposite to the two sides of the hook 110. The third support part 510 and the fourth support part 520 are respectively provided with a third through hole 511 and a fourth through hole 521 for the pin 210 to pass through.

[0045] When the latch 210 is disengaged from the hook 110, the first support portion 310 and the second support portion 320 together fix and support the latch 210, so that the latch 210 remains in the state of being disengaged from the hook 110. When the hook 110 is located between the third support portion 510 and the fourth support portion 520, and the latch 210 is reset to pass into the hook 110, the latch 210 passes into the third through hole 511, the hook 110 and the fourth through hole 521 in sequence. When the latch 210 is in the state of passing into the hook 110, the first support portion 310, the second support portion 320, the third support portion 510 and the fourth support portion 520 together fix and support the latch 210, further strengthening the locking relationship between the latch 210 and the hook 110, and the anti-toppling device 10 can withstand a higher degree of shaking. At the same time, in addition to the fact that the latch 210 can prevent the box 21 from toppling forward, the cooperation between the third support portion 510, the fourth support portion 520, the latch 210 and the hook 110 can also prevent the box 21 from toppling to the left or to the right.

[0046] Preferably, the second support 500 can be made of POM (polyformaldehyde) or PA (polyamide) material. PA material has the characteristics of self-lubrication and low friction coefficient. During the process of the latch 210 passing into and disengaging from the hook 110, the latch 210 needs to frequently pass through the third through hole 511 and the fourth through hole 521. On the one hand, the second support 500 can support and guide the latch 210. On the other hand, the characteristics of self-lubrication and low friction coefficient can lubricate the latch 210 and reduce the friction and wear between the latch 210 and the second support 500. The third support portion 510 can be stacked on the side of the second support portion 320, so that the third through hole 511 and the second through hole 321 are connected, and the latch 210 can smoothly transition between the third through hole 511 and the second through hole 321, avoiding the situation that the latch 210 cannot be accurately reset after being disengaged from the third through hole 511.

[0047] Please refer to Figure 2 and Figure 4In an embodiment, the latch assembly 200 further comprises a flange 230 and an elastic member 240, the flange 230 is located between the first support portion 310 and the second support portion 320, and the elastic member 240 is limited between the first support portion 310 and the flange 230; when the latch 210 is separated from the hook 110, the flange 230 presses the elastic member 240 towards the first support portion 310; when the latch 210 penetrates into the hook 110, the elastic member 240 pushes the flange 230 towards the hook 110.

[0048] As can be seen from the above, the latch 210 penetrates through the first through hole 311 and the second through hole 321, the flange 230 is sleeved on the outer periphery of the latch 210 and located between the first support portion 310 and the second support portion 320, so that the flange 230 is limited between the first support portion 310 and the second support portion 320 by setting the outer diameter of the flange 230 to be greater than the inner diameter of the first through hole 311 and the second through hole 321. The elastic member 240 is sleeved on the outer periphery of the latch 210, and the elastic member 240 is set between the flange 230 and the first support portion 310, and the minimum inner diameter of the elastic member 240 is set to be greater than the inner diameter of the first through hole 311 and less than the outer diameter of the flange 230, so that the elastic member 240 is limited between the flange 230 and the first support portion 310.

[0049] It can be understood that the flange 230 is fixedly connected to the bolt 210, the second support part 320 and the first support part 310 are located on the right side of the hook 110, and the second support part 320 and the first support part 310 are arranged left and right, the flexible part 220 is connected to the right end of the bolt 210, and when the bolt 210 is in the state of penetrating into the hook 110, the flexible part 220 pulls the bolt 210 to move to the right end, and the bolt 210 is separated from the hook 110; because the flange 230 is connected to the bolt 210, the flange 230 moves to the right end with the bolt 210, the flange 230 abuts against the elastic part 240 limited between the flange 230 and the first support part 310, and the elastic part 240 is in an elastic compression state. Because the flexible part 220 has low rigidity and cannot apply external force to push the bolt 210 to move to the hook 110, the elastic force of the elastic part 240 is used to reset the bolt 210 to the state of penetrating into the hook 110. When the bolt 210 is not affected by external force, that is, the flexible part 220 no longer pulls the bolt 210, because the elastic part 240 is in an elastic compression state, it has a trend of expansion and expansion, and then pushes the flange 230 to move to the left end, that is, drives the bolt 210 to move to the left end, that is, drives the bolt 210 to move to the direction of penetrating into the hook 110.

[0050] When the flange 230 abuts against the second support part 320, the bolt 210 reaches the maximum distance of moving to the hook 110, preferably, the state of the elastic part 240 at this time is set to an elastic compression state, so that the final position that the bolt 210 can reach remains unchanged every time the bolt 210 is reset from the separated state to the state of penetrating into the hook 110, and it is ensured that the bolt 210 can penetrate into the hook 110 under the pushing of the elastic part 240. The elastic part 240 includes but is not limited to a compression spring.

[0051] The first support 300 comprises a bottom plate 330 connected to the top wall of the box body 21, specifically, the bottom plate 330 can be connected to the top wall of the box body 21 by screws or bolts, and the first support part 310 and the second support part 320 are vertically arranged on the bottom plate 330. Considering that the outer diameter of the flange 230 is greater than the inner diameter of the first through hole 311 and the second through hole 321, the bolt 210 cannot be directly connected through the first through hole 311 and the second through hole 321. Therefore, the first support part 310 is arranged to be detachably connected to the bottom plate 330, one end of the bolt 210 passes through the second through hole 321, the other end passes through the first through hole 311, and then the first support part 310 is connected to the bottom plate 330, so that the flange 230 is limited between the first support part 310 and the second support part 320, and the second support part 320 and the bottom plate 330 can be first formed, and the first support part 310 can be connected to the bottom plate 330 by screws or bolts. Similarly, the second support part 320 can be arranged to be detachably connected to the bottom plate 330, and the first support part 310 and the second support part 320 can also be arranged to be detachably connected to the bottom plate 330 at the same time.

[0052] Please refer to Figure 3 In an embodiment, the guide 400 comprises a first pulley 410 located on the side of the first support part 310 away from the second support part 320, and the flexible member 220 is connected to one end of the bolt 210 close to the first pulley 410 and is arranged around the outer periphery of the first pulley 410.

[0053] The bolt 210 is arranged transversely on the first support 300 and can move reciprocally in the transverse direction, the first pulley 410 is located on the side of the first support part 310 away from the second support part 320, and the flexible member 220 is connected to one end of the bolt 210 close to the first pulley 410. Taking the example that the second support part 320 and the first support part 310 are arranged left and right, the first pulley 410 is located on the right side of the first support part 310, and the flexible member 220 is connected to the right end of the bolt 210, which indicates that the flexible member 220 is first extended to the right after being connected to the bolt 210, so that the flexible member 220 can pull the bolt 210 to the right. The flexible member 220 is turned by the first pulley 410 and then extends to the side of the box body 21 close to the box door. Specifically, it can extend to the side of the box body 21 where the box door is located, i.e. the front side, or it can extend to the position close to the front side on the left side and the right side of the box body 21.

[0054] It can be understood that when the first pulley 410 is arranged on the right side of the first supporting part 310 and is located at the front side in the horizontal direction of the pin 210, the flexible part 220 pulls the pin 210 to move to the right, and the pin 210 also has a movement trend to move to the front side, that is, the pin 210 moves in a direction deviating from its original arrangement direction, which causes the pin 210 to rub against the first supporting plate more severely when the pin 210 is separated from the hook 110, and also causes the pin 210 to fail to pass into the hook 110 again when the pin 210 is reset. Similarly, when the first pulley 410 is arranged on the right side of the first supporting part 310 and is located at the rear side in the horizontal direction of the pin 210, the same effect on the movement of the pin 210 is caused.

[0055] Therefore, in an embodiment, the first pulley 410 is arranged in the horizontal direction of the pin 210, that is, the first pulley 410 and the pin 210 are arranged on the same line, so that the movement direction of the pin 210 is consistent with the original arrangement direction of the pin 210 during the process of passing into or separating from the hook 110, the friction and abrasion between the pin 210 and the first supporting plate are reduced, and the pin 210 is ensured to pass into the hook 110 stably when the pin 210 is reset.

[0056] Please continue to refer to Figure 3 In an embodiment, the guide part 400 further comprises two second pulleys 420 arranged adjacently, and the two second pulleys 420 are arranged at one end of the top wall of the box body 21 close to the box door. The end of the flexible part 220 away from the pin 210 is arranged to pass through the two second pulleys 420 adjacently and extend towards the side wall of the box body 21. A first clamping bead 221 is connected to the flexible part 220, and the first clamping bead 221 is limited to one side of the second pulley 420 close to the side wall of the box body 21.

[0057] The extending direction of the flexible part 220 arranged around the first pulley 410 can be adjusted and changed. By arranging the two second pulleys 420 adjacently and arranging the flexible part 220 to pass through the two second pulleys 420 adjacently after being arranged around the first pulley 410, the extending direction of the flexible part 220 arranged around the first pulley 410 is fixed. After the flexible part 220 passes through the two second pulleys 420 adjacently, the flexible part 220 extends towards the side wall of the box body 21. Specifically, when the second pulley 420 is arranged close to the right side of the box body 21, the flexible part 220 can extend towards the front side wall or the right side wall of the box body 21; and when the second pulley 420 is arranged close to the left side of the box body 21, the flexible part 220 can extend towards the front side wall or the right side wall of the box body 21.

[0058] When the flexible member 220 pulls the plug 210 away from the hook 110, the user achieves this by pulling the end of the flexible member 220 away from the plug 210 towards the outside of the box 21. By providing the first clamping bead 221 on the flexible member 220 and limiting the first clamping bead 221 to one side of the second pulley 420 close to the side wall of the box 21, the end of the flexible member 220 away from the plug 210 always passes through the two second pulleys 420 and is located on the side of the box 21 close to the box door, that is, the part of the flexible member 220 for the user to pull is always located on the side of the second pulley 420 close to the side wall of the box 21.

[0059] The installation steps of the anti-toppling device 10 for household appliances are as follows: first, install the plug assembly 200 on the top wall of the box 21 of the household appliance, and then install the hook assembly 100 on the stop wall 30 according to the height position of the plug 210; then, the box 21 needs to be pushed into the installation space until the box 21 leans against the stop wall 30. Before pushing the box 21 in, the flexible member 220 needs to be pulled so that the plug 210 is in a position away from the hook 110, avoiding the hook 110 stopping the plug 210, which causes the box 21 to be unable to continue to be pushed in. When the box 21 is pushed in to lean against the stop wall 30, the flexible member 220 is released, so that the plug 210 is reset and penetrates into the hook 110, realizing the anti-toppling effect of the anti-toppling device 10 on the household appliance. When the household appliance needs to be moved to the installation space, the plug 210 needs to be moved to a position away from the hook 110 before the box 21 can continue to be moved.

[0060] Specifically, the flexible member 220 can be a rope, the hook assembly 100 includes a fixed plate 120 and a hook 110, the fixed plate 120 is connected to the stop wall 30, and the hook 110 is arranged on the fixed plate 120. Specifically, the fixed plate 120 can be connected to the stop wall 30 by screws or bolts, and the hook 110 can be welded to the fixed plate 120.

[0061] As can be seen from the above, when the box 21 is pushed in and pushed out, the plug 210 needs to be moved to a position away from the hook 110, that is, the flexible member 220 needs to be kept in a state of being pulled. Obviously, this requires the user to pull the flexible member 220 while pushing in or pushing out the box 21, which causes the user to operate inconveniently.

[0062] In view of this, please refer to Figure 5 and Figure 6In an embodiment, the household appliance further comprises a top cover 22, which is arranged on the top wall of the cabinet 21, and is provided with a lead-out hole on one side close to the second pulley 420. A clamping protrusion 24 extending outward of the cabinet 21 is arranged on the top cover 22 along the circumference of the lead-out hole. The outer end of the clamping protrusion 24 is provided with a notch groove 25 communicating the inner and outer surfaces thereof. The flexible member 220 passes through the notch groove 25, and the primary clamping bead 221 abuts against the outer surface of the clamping protrusion 24. The latch 210 is separated from the hook 110.

[0063] After the end of the flexible member 220 away from the latch 210 passes through two adjacent second pulleys 420, it then passes through the lead-out hole and finally locates on the side of the cabinet 21 close to the cabinet door. Specifically, when the second pulley 420 is arranged close to the right side of the cabinet 21, the lead-out hole can be arranged on the front side or the right side of the top cover 22. When the second pulley 420 is arranged close to the left side of the cabinet 21, the lead-out hole can be arranged on the front side or the left side of the top cover 22. When the latch 210 is in the state of penetrating into the hook 110, the primary clamping bead 221 does not pass through the lead-out hole, i.e., is located on the inner side of the top cover 22. During the process of pulling the flexible member 220 outward of the cabinet 21, the primary clamping bead 221 passes through the lead-out hole until the latch 210 is separated from the hook 110. When the flexible member 220 passes through the notch groove 25 and the primary clamping bead 221 abuts against the outer surface of the clamping protrusion 24, the primary clamping bead 221 plays a role of fixing the flexible member 220. The flexible member 220 and the latch 210 remain relatively stationary, and the latch 210 maintains the state of being separated from the hook 110. When it is necessary to reset the latch 210 to the state of penetrating into the hook 110, it is only necessary to pass the primary clamping bead 221 through the lead-out hole and re-enter the inner side of the top cover 22.

[0064] When it is necessary to push the cabinet 21 into or out of the installation space, it is only necessary to first pull the flexible member 220 outward of the cabinet 21, so that the flexible member 220 passes through the notch groove 25 and the primary clamping bead 221 abuts against the outer surface of the clamping protrusion 24, so that the latch 210 remains in the state of being separated from the hook 110. The user only needs to push and pull the cabinet 21, further simplifying the installation and operation of the anti-toppling device 10 for household appliances.

[0065] Meanwhile, the top cover 22 arranged on the top wall of the cabinet 21 also plays a role of shielding the latch assembly 200, improving the overall aesthetics of the household appliance.

[0066] When the bolt assembly 200 is installed on the top wall of the cabinet 21 away from the cabinet door, the distance between the first pulley 410 assembly and the second pulley 420 assembly is far, and the flexible member 220 is only arranged on the first pulley 410 assembly. When the pulling force at both ends of the flexible member 220 is insufficient, the part of the flexible member 220 between the first pulley 410 assembly and the second pulley 420 assembly will sag, causing the flexible member 220 to fall off the first pulley 410 assembly.

[0067] Please refer to Figure 3 and Figure 7 Therefore, in an embodiment, the guide member 400 further comprises a third pulley 430 and two adjacent fourth pulleys 440 between the first pulley 410 and the second pulley 420. The arrangement direction of the third pulley 430 and the fourth pulley 440 is parallel to the horizontal arrangement direction of the bolt 210. The flexible member 220 is sequentially arranged on the first pulley 410, the third pulley 430, the two adjacent fourth pulleys 440, and the two adjacent second pulleys 420. The flexible member 220 is connected with a secondary clamping bead 222, and the secondary clamping bead 222 is limited on the side of the fourth pulley 440 close to the second pulley 420.

[0068] By adding the third pulley 430 and the two adjacent fourth pulleys 440, the flexible member 220 is arranged on the third pulley 430 and inserted between the two adjacent fourth pulleys 440. The third pulley 430 and the fourth pulley 440 support the flexible member 220 to some extent, reducing the sagging tendency of the part of the flexible member 220 between the first pulley 410 assembly and the second pulley 420 assembly. At the same time, by arranging the secondary clamping bead 222 on the flexible member 220 and limiting it on the side of the fourth pulley 440 close to the second pulley 420, i.e., limiting the maximum length of the part of the flexible member 220 between the first pulley 410 and the fourth pulley 440, when the secondary clamping bead 222 abuts against the fourth pulley 440. The length of the part of the flexible member 220 between the first pulley 410 and the fourth pulley 440 reaches the maximum, and the shorter the part of the flexible member 220 between the first pulley 410 and the fourth pulley 440, the weaker the sagging phenomenon of the flexible member 220, and the less likely the flexible member 220 to fall off the first pulley 410.

[0069] Specifically, the first pulley 410, the second pulley 420, the third pulley 430 and the fourth pulley 440 include a bolt 450 connected to the cabinet 21, a sleeve 460 and a pulley body 470 sleeved on a stud 452 of the bolt 450, the pulley body 470 is located between the sleeve 460 and a nut 451 of the bolt 450, the pulley body 470 is provided with a connecting groove 471 arranged in a circumferential direction, and the flexible member 220 is arranged in the connecting groove 471. When the flexible member 220 is pulled outward by an external force, or the flexible member 220 moves due to the elastic force of the elastic member 240, the pulley body 470 is driven to rotate, thereby reducing the friction and wear between the flexible member 220 and the pulley body 470.

[0070] The application further provides a refrigerator 20.

[0071] Please refer to Figure 1 In the embodiment, the refrigerator 20 includes the cabinet 21 and the anti-toppling device 10 for household appliances as described above, and the cabinet 21 is provided with a cabinet door on one side. Since the refrigerator 20 adopts all the technical solutions of all the above embodiments, it has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0072] To further improve the anti-toppling capability of the anti-toppling device 10 for household appliances on the refrigerator 20, the refrigerator 20 includes two anti-toppling devices 10 for household appliances, and the two anti-toppling devices 10 for household appliances are symmetrically arranged in the front-rear direction of the cabinet 21.

[0073] The above description is only the preferred embodiments of the application, and does not limit the patent scope of the application. Any equivalent structural transformation made according to the content of the specification and drawings, or direct / indirect application in other related technical fields within the concept of the application is included in the patent protection scope of the application.
