Description

Technical Field

[0001] The present invention relates to the field of disinfection cabinets, and particularly to an exhaust disinfection cabinet. Background Art

[0002] A disinfection cabinet is a household appliance that uses hot air and ultraviolet rays to disinfect and dry tableware. During the drying and disinfection process, the moisture on the surface of the tableware gradually evaporates, increasing the humidity inside the cabinet and gradually reducing the evaporation efficiency of the moisture on the surface of the tableware. Therefore, it takes a long time to complete the drying of the tableware. Summary of the Invention

[0003] Based on this, in view of the problem of insufficient drying speed of tableware by the disinfection cabinet, it is necessary to provide an exhaust disinfection cabinet.

[0004] An exhaust disinfection cabinet includes a cabinet body, a cabinet door, and a support rod. The support rod is installed on the inner wall of the cabinet body to support the edge of the tray. The cabinet door is movably installed on the cabinet body, and the cabinet door has a closed state and an open state.

[0005] The support rod includes a rod body, a first end cap, a second end cap, an elastic member, a first magnetic attraction member, and a sealing member.

[0006] An exhaust cavity is provided inside the rod body. The exhaust cavity extends along the axial direction of the rod body and penetrates to both ends of the rod body. First exhaust holes and second exhaust holes are provided on the side wall of the exhaust cavity, and the first exhaust holes and the second exhaust holes penetrate to the outer wall of the rod body.

[0007] The first end cap and the second end cap are respectively installed at both ends of the exhaust cavity. The sealing member is slidably disposed in the exhaust cavity, and a third exhaust hole is provided on the sealing member. Both ends of the elastic member are respectively disposed on the first end cap and the sealing member. The first magnetic attraction member is installed on the sealing member.

[0008] A second magnetic attraction member is installed on the cabinet door. A fourth exhaust hole is provided on the inner wall of the cabinet body, and the fourth exhaust hole communicates with the outer wall of the cabinet body. The first exhaust hole is located at the fourth exhaust hole and communicates with the fourth exhaust hole.

[0009] When the cabinet door is in the open state, the sealing member blocks the first exhaust hole to disconnect the fourth exhaust hole and the exhaust cavity.

[0010] When the cabinet door is in the closed state, the first magnetic attraction member and the second magnetic attraction member are magnetically attracted to each other, so that the elastic member is in a stretched state. The third exhaust hole is located at the first exhaust hole and communicates with the first exhaust hole, so that the fourth exhaust hole and the exhaust cavity communicate.

[0011] The exhaust disinfection cabinet of the present invention further includes a heater installed in the cabinet body. At least a part of the second exhaust holes are located on the bottom wall of the exhaust cavity, and the heater is located below the support rod.

[0012] In the present invention, the second end cover is detachably installed at the end of the exhaust cavity. The sealing member extends along the axial direction of the rod body. The material of the sealing member is magnetic metal. The first magnetic attraction member is a magnet. The elastic member is installed at one end of the sealing member, and the first magnetic attraction member is magnetically attracted to the other end of the sealing member, so that the first magnetic attraction member is spaced from the side wall of the exhaust cavity.

[0013] In the present invention, a positioning groove is provided on the second end cover. When the cabinet door is in the closed state, the sealing member abuts against the second end cover, so that the first magnetic attraction member is located in the positioning groove, and the first magnetic attraction member fits against the side wall of the positioning groove to obtain positioning in the radial direction of the rod body.

[0014] In the present invention, when the first magnetic attraction member is located in the positioning groove, the first magnetic attraction member is in interference fit with the side wall of the positioning groove.

[0015] In the present invention, the elastic member is a spring.

[0016] In the present invention, the elastic member is an elastic rope. A part of the first end cover is located in the exhaust cavity. When the cabinet door is in the open state, the first end cover abuts against the sealing member, so that the elastic member is in a straightened state.

[0017] In the present invention, the sealing member fits against the side wall of the exhaust cavity, so that the sealing member obtains a moving guide in the axial direction of the rod body. A first avoidance groove is provided on the sealing member. The first avoidance groove extends along the axial direction of the rod body. At least a part of the second exhaust holes are located at the first avoidance groove and communicate with the first avoidance groove.

[0018] In the present invention, a bending plate is provided on the outer wall of the rod body. The bending plate and the rod body enclose to form a support groove;

[0019] The support rod further includes a connecting member. The connecting member includes a plugging plate and a plugging column. The end of the plugging column is fixed on one side of the plugging plate. A shaft hole is provided in the middle of the plugging column, and the shaft hole penetrates through the plugging plate;

[0020] The plugging column is plugged at the fourth exhaust hole. The top edge of the plugging plate is located in the support groove, and the bending plate supports on the top edge of the plugging plate, so that the first exhaust hole communicates with the shaft hole.

[0021] A water collecting cavity is further arranged in the rod body of the present invention. The water collecting cavity is arranged at an interval from the exhaust cavity. A water leakage port is arranged on the top side wall of the water collecting cavity, and the water leakage port penetrates through to the outer wall of the rod body. A support rib is arranged on the outer wall of the rod body, and the support rib is located at the edge of the water leakage port. The support plate is supported on the support rib to allow the support plate to avoid the second exhaust hole.

[0022] The beneficial effects of the present invention are as follows:

[0023] When the cabinet door is in the closed state, the second magnetic part magnetizes the first magnetic part, so that the sealing part moves towards the second end cover and stretches the elastic part. Finally, the third exhaust hole can be communicated with the fourth exhaust hole through the first exhaust hole, and then communicated to the outside of the cabinet body. During the heating and disinfection process of tableware, based on the humidity difference and temperature difference inside and outside the cabinet body, the air inside the cabinet body will spontaneously enter the exhaust cavity through the second exhaust hole and then be discharged from the cabinet body through the fourth exhaust hole, so as to reduce the humidity inside the cabinet body. Thus, the evaporation rate of the water on the surface of the tableware can always be maintained at a relatively high value, and then the heating speed of the tableware is increased. At the same time, the first magnetic part and the second magnetic part magnetize each other, so that the cabinet door can be relatively stably maintained in the closed state, reducing the occurrence of the situation that the user accidentally opens the door during the disinfection process and improving the safety.

[0024] When the cabinet door is in the open state, the elastic part begins to recover and makes the sealing part begin to move towards the first end cover. Finally, the first exhaust hole and the third exhaust hole are staggered, and the sealing part blocks the first exhaust hole to disconnect the exhaust cavity and the fourth exhaust hole, avoiding the air with peculiar smell outside the cabinet body from entering the exhaust cavity through the fourth exhaust hole and polluting the inside of the cabinet body.

[0060] Embodiment:

[0061] This embodiment provides an exhaust disinfection cabinet, which includes a cabinet body, a cabinet door, a support rod and a tray.

[0062] The cabinet door is movably installed on the cabinet body, such as in a drawer-type installation or a rotary installation, so that the cabinet door has a closed state and an open state. It can be understood that when the cabinet door is in the closed state, the distance between the cabinet door and the cabinet body is the smallest, and when the cabinet door is in the open state, the distance between the cabinet door and the cabinet body is larger.

[0063] There are two support rods, which are respectively horizontally installed on the left inner wall and the right inner wall of the cabinet body, and the left edge and the right edge of the tray can be respectively supported on the two support rods.

[0064] Among them, the cabinet body is installed in the cabinet. Except for the position where the cabinet door is located (the front side of the cabinet body), the gaps between the cabinet body and the cabinet, whether it is the left outer wall, the right outer wall, the rear outer wall, the top outer wall or the bottom outer wall, are relatively small. Therefore, these gaps are usually cleaning blind spots, which are prone to breed bacteria and generate odors. And because the front side of the cabinet body has a larger space, it usually does not belong to the cleaning blind spot. Coupled with frequent ventilation, the air hygiene condition on the front side of the cabinet body is relatively good.

[0065] The exhaust disinfection cabinet further includes a heater and an ultraviolet lamp installed in the cabinet body. The heater can heat the inside of the cabinet body to dry and disinfect tableware. The ultraviolet lamp can not only disinfect tableware with ultraviolet rays, but also the ozone generated by ultraviolet rays can also disinfect tableware.

[0066] The above parts are all prior art and will not be elaborated in this embodiment.

[0067] See Figures 1 - 27 , what is different between this embodiment and the prior art is that the support rod includes a rod body 1, a first end cap 2, a second end cap 3, an elastic member 4, a first magnetic member 5 and a seal member 6.

[0068] Specifically see Figure 9 , Figure 18 and Figure 23, an exhaust cavity 11 is provided inside the rod body 1. The exhaust cavity 11 extends along the axial direction of the rod body 1 and penetrates through both ends of the rod body 1. Among them, a first exhaust hole 111 and a second exhaust hole 112 are provided on the side wall of the exhaust cavity 11, and both the first exhaust hole 111 and the second exhaust hole 112 penetrate through to the outer wall of the rod body 1. The first end cap 2 and the second end cap 3 are respectively installed at both ends of the exhaust cavity 11 to seal the ends of the exhaust cavity 11.

[0069] See Figure 12 and Figure 13 , the seal 6 is strip-shaped, and a number of third exhaust holes 61 are provided on the seal 6. See Figures 15 - 27 , the seal 6 extends along the axial direction of the rod body 1. Therefore, the extension direction of the seal 6 is the same as the extension direction of the exhaust cavity 11. At the same time, since the cross-sectional shape of the seal 6 is adapted to the cross-sectional shape of the exhaust cavity 11, the seal 6 can be slidably arranged in the exhaust cavity 11 along the axial direction of the rod body 1. Since the seal 6 is in contact with the side wall of the exhaust cavity 11 and the cross-sectional shape of the seal 6 matches the cross-sectional shape of the exhaust cavity 11, the seal 6 is guided and limited during the movement along the axial direction of the rod body 1.

[0070] See Figure 14 , Figure 16 , Figure 19 and Figure 24 , both ends of the elastic member 4 are respectively arranged on the first end cap 2 and the seal 6 to allow the seal 6 to drive the elastic member 4 to deform during the movement. See Figure 17 , Figure 20 and Figure 25 , the first magnetic member 5 is installed on the seal 6.

[0071] Fourth exhaust holes are provided on both the left inner wall and the right inner wall of the cabinet body, and the fourth exhaust holes communicate with the left outer wall or the right outer wall of the cabinet body. The number of the fourth exhaust holes is the same as that of the first exhaust holes 111, and the positions match each other so that the fourth exhaust holes and the first exhaust holes 111 are in a one-to-one correspondence. After the support rod is installed on the inner wall of the cabinet body, the first exhaust holes 111 are located at the corresponding fourth exhaust holes so that the first exhaust holes 111 can communicate with the left outer wall or the right outer wall of the cabinet body through the corresponding fourth exhaust holes, and then communicate with the narrow gap between the cabinet body and the cabinet.

[0072] A second magnetic member is installed on the cabinet door. It is easy to understand that when the cabinet door is in the closed state, the distance between the second magnetic member and the first magnetic member 5 is relatively small, so the two can generate a relatively obvious mutual magnetic attraction effect. When the cabinet door is in the open state, the distance between the second magnetic member and the first magnetic member 5 is relatively large, and the two are not within the effective magnetic attraction range.

[0073] See Figures 23 - 27In this embodiment, when the cabinet door is in the closed state, the first magnetic member 5 and the second magnetic member are magnetically attracted to each other, so that the first magnetic member 5 moves toward the second magnetic member, and the first magnetic member 5 drives the sealing member 6 to move toward the second end cover 3, and the sealing member 6 also stretches the elastic member 4. Thus, the third exhaust hole 61 can move to the first exhaust hole 111 and communicate with the first exhaust hole 111. Correspondingly, at this time, the exhaust cavity 11 can be connected to the fourth exhaust hole through the third exhaust hole 61 and the first exhaust hole 111, and then connected to the gap between the cabinet body and the cabinet.

[0074] During the disinfection process, when the cabinet door is in a closed state, and the heater and the ultraviolet lamp are both in working state, the heater can increase the temperature inside the cabinet and increase the humidity inside the cabinet by evaporating the moisture on the surface of the tableware. The ultraviolet lamp can generate ozone inside the cabinet. Based on the temperature difference, humidity difference and ozone concentration difference, the high-temperature air in the cabinet will carry water vapor and ozone and enter the exhaust cavity 11 through the second exhaust hole 112 spontaneously, and then flow to the gap between the cabinet and the cabinet through the third exhaust hole 61, the first exhaust hole 111 and the fourth exhaust hole. The following two benefits can be achieved. On the one hand, the humidity in the cabinet is reduced, so that the evaporation rate of the moisture on the surface of the tableware can always be maintained at a higher value, thereby improving the drying speed of the tableware. On the other hand, the high-temperature air and ozone will disinfect the gap between the cabinet and the cabinet (cleaning blind spot).

[0075] In the above process, the high-temperature air at the first exhaust hole 111 flows from the cabinet to the outside of the cabinet, which can effectively prevent the odorous air between the cabinet and the cabinet from flowing into the exhaust cavity 11 from the first exhaust hole 111. In addition, the first magnetic attraction member 5 and the second magnetic attraction member are magnetically attracted to each other, so that the cabinet door can be kept in a closed state more stably, reducing the occurrence of users opening the door by mistake during the disinfection process, and improving safety.

[0076] In this embodiment, when the cabinet door is in a closed state, the seal 6 also abuts against the second end cover 3, so that the seal 6 can be positioned in the axial direction of the rod body 1 to ensure that the third exhaust hole 61 can be aligned with the first exhaust hole 111.

[0077] See also Figures 15 - 22 When the cabinet door is in the open state, the second magnetic member no longer attracts the first magnetic member 5, and the elastic member 4 begins to recover, so that the sealing member 6 begins to move toward the first end cover 2, and finally the first exhaust hole 111 and the third exhaust hole 61 are staggered, and the sealing member 6 blocks the first exhaust hole 111, thereby the exhaust cavity 11 will be disconnected from the fourth exhaust hole and the first exhaust hole 111. It is not difficult to understand that the air with odor between the cabinet and the cupboard is prevented from entering the exhaust cavity 11 through the fourth exhaust hole and the first exhaust hole 111 to pollute the interior of the cabinet.

[0078] In this embodiment, the elastic member 4 is an elastic rope. If the elastic rope is subjected to a tensile force, it will be straightened and stretched. If the elastic rope is subjected to a compressive force, it will not contract but bend and deform. This results in the position of the sealing member 6 in the exhaust cavity 11 not being unique when the cabinet door is in the open state, and thus it is impossible to ensure the shielding effect of the sealing member 6 on the first exhaust hole 111.

[0079] To solve the above problems, referring to Figure 16 and Figure 19 , a part of the first end cap 2 of this embodiment is located in the exhaust cavity 11. When the cabinet door is in the open state, the first end cap 2 abuts against the sealing member 6. At this time, the elastic member 4 is still in a straightened state. Thus, when the cabinet door is in the open state, the sealing member 6 can also be positioned axially on the rod body 1, thereby ensuring that the sealing member 6 can shield the first exhaust hole 111.

[0080] It is not difficult to understand that when the cabinet door is in the open state, by limiting the sealing member 6 with the first end cap 2, it is also possible to prevent the distance between the sealing member 6 and the second end cap 3 from being too large, so that when the cabinet door is closed again, it is ensured that the second magnetic member and the first magnetic member 5 are still within the effective magnetic attraction distance range.

[0081] In some other embodiments, the elastic member 4 can also be a spring. When the cabinet door is in the open state, if the spring is in a deformed state (whether compressed or stretched), it can spontaneously drive the sealing member 6 to move to adjust the position of the sealing member 6 to ensure that ultimately the sealing member 6 can shield the first exhaust hole 111, and at the same time the distance between the first magnetic member 5 and the second end cap 3 will not be too large. In this part of the embodiments, when the cabinet door is in the open state, the first end cap 2 does not need to abut against the sealing member 6

[0082] Referring to Figures 7 - 9 , in this embodiment, a part of the second exhaust holes 112 are located on the bottom wall of the exhaust cavity 11, and a part of the second exhaust holes 112 are located on the top wall of the exhaust cavity 11. In some embodiments, if the edge of the tray is supported on the top of the rod body 1, the second exhaust holes 112 at the top wall of the exhaust cavity 11 will be blocked, while the second exhaust holes 112 at the bottom wall of the exhaust cavity 11 are not blocked by the tray. In this embodiment, the edge of the tray is not supported on the top of the rod body 1, so all the second exhaust holes 112 are not blocked by the tray.

[0083] Referring to Figure 21 、 Figure 22 、 Figure 26 and Figure 27, based on the shape of the bottom of the cross-section of the seal 6 in this embodiment, during the movement of the seal 6, it always avoids the second exhaust hole 112 at the bottom wall of the exhaust cavity 11. At the same time, since the second exhaust hole 112 at the bottom wall of the exhaust cavity 11 is not blocked by the support plate, the exhaust cavity 11 can always be connected to the inside of the cabinet body at least through the second exhaust hole 112 at its bottom. If the cabinet door is in the closed state, the air inside the cabinet body can enter the exhaust cavity 11 through the second exhaust hole 112 at the bottom of the exhaust cavity 11, and then be discharged into the gap between the cabinet body and the cabinet. If the cabinet door is in the open state, the air in the exhaust cavity 11 can be connected to the inside of the cabinet body through the second exhaust hole 112 at the bottom of the exhaust cavity 11, and then be connected to the front opening of the cabinet body for ventilation, so as to discharge the ozone in the cabinet body.

[0084] Considering that hot air flows from bottom to top, in this embodiment, the heater is arranged below the support rod to allow hot air to directly enter the exhaust cavity 11 through the second exhaust hole 112 at the bottom of the exhaust cavity 11 during the disinfection process.

[0085] See Figure 12 and Figure 13 , a first avoidance groove 62 is provided on the seal 6 in this embodiment, and the first avoidance groove 62 extends along the axial direction of the rod body 1. See Figure 21 and Figure 26 , in this embodiment, the second exhaust hole 112 at the top wall of the exhaust cavity 11 is located at the first avoidance groove 62 and is communicated with the first avoidance groove 62 to prevent the seal 6 from blocking the second exhaust hole 112 at the top wall of the exhaust cavity 11 during movement. At the same time, since the edge of the support plate in this embodiment is not supported on the top of the rod body 1, the second exhaust hole 112 at the top wall of the exhaust cavity 11 can always keep the exhaust cavity 11 and the inner wall of the cabinet body in a connected state. The seal 6 avoids the second exhaust hole 112 through the first avoidance groove 62, which can reduce the limitation on the cross-sectional shape of the seal 6 to ensure that the side wall of the exhaust cavity 11 effectively positions and guides the seal 6.

[0086] In some usage scenarios, the exhaust disinfection cabinet will be idle for a long time. At this time, the cabinet door will be in the closed state for a long time. Considering the hygiene requirements, the seal 6 also needs to block the first exhaust hole 111 at this time. For this reason, it is necessary to remove the first magnetic part 5 from the seal 6 to prevent the second magnetic part from driving the seal 6 to move.

[0087] To facilitate the disassembly and assembly of the first magnetic member 5, the second end cap 3 is usually detachably installed at the end of the exhaust cavity 11 in a plug-in manner. The elastic member 4 is installed at one end of the seal 6, and the first magnetic member 5 is located at the other end of the seal 6. Thus, the first magnetic member 5 can be as close as possible to the end of the exhaust cavity 11. When the second end cap 3 is removed, the user can more conveniently access the first magnetic member 5 for disassembly and assembly. Among them, the second magnetic member and the seal 6 are both made of magnetic metal and cannot be directly magnetically attracted to each other. However, the first magnetic member 5 is a magnet. Therefore, the first magnetic member 5 can magnetically attract both the seal 6 and the second magnetic member. When the second end cap 3 is removed, to facilitate removing the first magnetic member 5 from the seal 6, the first magnetic member 5 is spaced from the side wall of the exhaust cavity 11.

[0088] Preferably, a positioning groove 31 is provided on the second end cap 3. The shape of the first magnetic member 5 is adapted to the shape of the positioning groove 31. The first magnetic member 5 can enter the positioning groove 31 and fit against the side wall of the positioning groove 31 to obtain positioning. See Figure 25 , if it is necessary to remagnetize the first magnetic member 5 on the seal 6, the first magnetic member 5 can be first placed in the positioning groove 31, and then the second end cap 3 is covered so that the seal 6 and the first magnetic member 5 are magnetically attracted to each other. After the seal 6 and the first magnetic member 5 are remagnetically contacted, the seal 6 will bring the first magnetic member 5 out of the positioning groove 31. This method ensures that finally the first magnetic member 5 can still be spaced from the side wall of the exhaust cavity 11, thus facilitating the next disassembly.

[0089] Further preferably, when the first magnetic member 5 is located in the positioning groove 31, the first magnetic member 5 is in interference fit with the side wall of the positioning groove 31. Before the seal 6 and the first magnetic member 5 are remagnetically attracted and contacted, the magnetic attraction force between the seal 6 and the first magnetic member 5 is not sufficient to move the first magnetic member 5 in the positioning groove 31. Thus, it can be ensured that finally the magnetic attraction position of the first magnetic member 5 on the seal 6 is in place.

[0090] See Figure 8 , in this embodiment, a bending plate 12 is provided on the outer wall of the rod body 1. The bending plate 12 and the rod body 1 enclose a support groove 13, and the opening of the support groove 13 faces downward.

[0091] See Figure 10 and Figure 11 , the support rod of this embodiment further includes a connecting member 14. The connecting member 14 includes a plug-in plate 141 and a plug-in column 142. The end of the plug-in column 142 is fixed on one side of the plug-in plate 141, and a shaft hole 143 is provided in the middle of the plug-in column 142. The shaft hole 143 penetrates the plug-in plate 141. The plug-in column 142 is plugged at the fourth exhaust hole, and thus the shaft hole 143 is in the middle of the fourth exhaust hole.

[0092] SeeFigure 21 , Figure 22 , Figure 26 and Figure 27 , the plug-in board 141 is perpendicular to the horizontal plane, the top edge of the plug-in board 141 is located in the support groove 13, the top edge of the plug-in board 141 supports the folding plate 12, so that the first exhaust hole 111 can communicate with the shaft hole 143.

[0093] The cooperation mode of the connecting piece 14 and the folding plate 12 allows the rod body 1 to be disassembled and assembled in the vertical direction. Generally speaking, the height of the cabinet is significantly greater than its width, so there is more space inside the cabinet in the height direction, so this disassembly and assembly method is more convenient.

[0094] See Figure 9 , in this embodiment, a water collecting cavity 15 is further arranged in the rod body 1, the water collecting cavity 15 is arranged at intervals with the exhaust cavity 11, the water collecting cavity 15 also extends along the axial direction of the rod body 1 and penetrates through both ends of the rod body 1, and the first end cover 2 and the second end cover 3 also seal both ends of the water collecting cavity 15. See Figure 6 , Figure 7 and Figure 9 , a water leakage port 151 is arranged on the top side wall of the water collecting cavity 15, the water leakage port 151 penetrates through the outer wall of the rod body 1, and a support rib 16 is arranged on the outer wall of the rod body 1, the support rib 16 extends along the axial direction of the rod body 1 and is located at the edge of the water leakage port 151. The edge of the tray can be supported on the support rib 16, so as to avoid the second exhaust hole 112. When the tray supports tableware, the water droplets on the tableware first flow along the upper surface of the tray to the side edge of the tray, and then flow to the lower surface of the tray. The water droplets are blocked by the support rib 16 during the flowing process on the lower surface of the tray, and then flow along the support rib 16 to the water leakage port 151 and enter the water collecting cavity 15, so that the occurrence of water droplets dripping below the tray can be reduced, thereby avoiding prolonging the drying time of the tableware below the tray.
