Description

Technical Field

[0001] The present application relates to the technical field of small household appliances, and particularly to a housing assembly of a cooking appliance and a cooking appliance. Background Art

[0002] Cooking appliances such as electric frying pans usually have drain holes provided at the feet at the bottom to timely drain the water that seeps into the outer shell, so as to avoid water wetting the internal electronic components and causing potential safety hazards. However, when such cooking appliances are placed in a sink for cleaning, the water in the sink easily backflows into the cooking appliance through the drain holes, thus causing potential safety hazards. Summary of the Utility Model

[0003] Based on this, it is necessary to provide a housing assembly of a cooking appliance and a cooking appliance to solve the problem of water backflow at the drain hole.

[0004] A housing assembly of a cooking appliance includes an outer shell and a drain valve. A support surface is provided at the bottom of the outer shell, and at least one drain hole is formed in the support surface. The drain valve is disposed at the drain hole. The drain valve includes a movable opening and closing member, and at least a part of the opening and closing member penetrates through the drain hole. When a part of the opening and closing member extends out of the outer shell from the support surface, the drain hole is closed; when the opening and closing member retracts into the outer shell, the drain hole is opened.

[0005] In the housing assembly of the cooking appliance provided by the present application, the drain hole can be opened and closed by the movement of the opening and closing member. When the cooking appliance is picked up for cleaning, the drain hole can be prevented from admitting water by moving the opening and closing member to the closed position, thus avoiding the problem of water backflow at the drain hole during cleaning. When the cooking appliance is placed on a tabletop, the support surface contacts the tabletop, so that the tabletop can press the opening and closing member into the outer shell. At this time, the drain hole is opened, and the water in the outer shell can be drained in time.

[0006] In one embodiment, the drain valve further includes an elastic member, and the elastic member acts on the opening and closing member to enable the opening and closing member to move to a position where the drain hole is closed.

[0007] Thus, when picking up the cooking appliance for cleaning, under the elastic force of the elastic member, the opening and closing member moves towards the position where the drain hole is closed, thereby closing the drain hole. When in use, when the cooking appliance is placed on the tabletop, as long as the elastic force of the elastic member is less than the gravity of the cooking appliance, the tabletop can push the opening and closing member to retract the opening and closing member into the housing, thereby opening the drain hole. It can be seen that in this embodiment, by providing the elastic member, during normal use, the drain hole is opened for normal drainage, and when picking up the cooking appliance for cleaning, the elastic force of the elastic member can cause the opening and closing member to move to automatically close the drain hole, thus avoiding the problem that the drain hole is in an open state during cleaning due to forgetting to move the opening and closing member or the gravity of the opening and closing member being unable to move the opening and closing member to the closed position.

[0008] In one embodiment, the drain valve further includes a pressing plate fixed inside the housing, and the elastic member abuts between the pressing plate and the opening and closing member to provide a force for the opening and closing member to move towards the closed position of the drain hole.

[0009] In this way, a space for installing the elastic member is formed between the pressing plate and the opening and closing member, and the structure is simple, making it easy to install the elastic member.

[0010] In one embodiment, the opening and closing member includes a trigger rod and a sealing member. The trigger rod passes through the drain hole, and the sealing member is connected to the outer wall of the trigger rod and is located inside the housing. When a part of the trigger rod extends out of the support surface and the sealing member abuts against one end of the drain hole, the drain hole is closed. When the trigger rod retracts into the housing and the sealing member moves away from the drain hole, the drain hole is opened.

[0011] In this way, the structure of the opening and closing member is very simple. By pushing the trigger rod to move, the movement of the sealing member can be controlled, thereby opening or closing the drain hole.

[0012] In one embodiment, the trigger rod is provided with a limiting rib, and the opening and closing member further includes a stop member. The sealing member and the stop member are sequentially sleeved outside the trigger rod, and the sealing member is clamped between the limiting rib and the stop member.

[0013] In this way, by providing the limiting rib and the stop member, it is convenient to connect the sealing member to the trigger rod, and the connection between the sealing member and the trigger rod is firm.

[0014] In one embodiment, the drain valve further includes an elastic member that acts on the opening and closing member to enable the opening and closing member to move to the position where the drain hole is closed. One end of the elastic member is sleeved outside the trigger rod and abuts against the stop member.

[0015] In this way, the trigger rod can limit the elastic member to prevent the elastic member from falling off.

[0016] In one embodiment, the seal is integrally formed on the outer wall of the trigger rod.

[0017] In this way, the structure of the opening and closing member is simpler.

[0018] In one embodiment, the seal is a silicone part.

[0019] In this way, the silicone part has a good sealing effect.

[0020] In one embodiment, when the drain hole is closed, the length of the trigger rod extending out of the support surface is L, and L is 2 mm to 5 mm.

[0021] In this way, when the cooking appliance is placed on the tabletop, the trigger rod will be squeezed by the tabletop and move 2 mm to 5 mm, so as to ensure that there is enough clearance between the seal and the end face of the drain hole, and ensure that the water in the housing can be discharged smoothly through the drain hole.

[0022] In one embodiment, the bottom of the housing is provided with feet, and the end faces of the feet constitute the support surface.

[0023] By providing feet at the bottom of the housing, there is a certain clearance between the bottom surface of the housing and the tabletop when the cooking appliance is placed on the tabletop, which is beneficial to the heat dissipation of the bottom of the cooking appliance.

[0024] A cooking appliance includes a cooking main body and the housing assembly as described above, and the housing assembly is arranged outside the cooking main body.

[0025] In this way, the cooking appliance can open and close the drain hole by the movement of the opening and closing member. When the cooking appliance is picked up for cleaning, the movement of the opening and closing member to the closed position can prevent water from entering at the drain hole, thus avoiding the problem of water backflow at the drain hole during cleaning. When the cooking appliance is placed on the tabletop, the support surface contacts the tabletop, so that the tabletop can press the opening and closing member into the housing. At this time, the drain hole is opened, and the water in the housing can be discharged in time. BRIEF DESCRIPTION OF THE DRAWINGS

The term "and / or" used in the description of this application includes any and all combinations of one or more of the related listed items.

[0038] Please refer to Figures 1 to 5 , this application provides a cooking appliance, including a cooking main body 200 and a housing assembly 100, and the housing assembly 100 is arranged outside the cooking main body 200. Among them, the housing assembly 100 includes a housing 10 and a drain valve 20. A support surface 111 is provided at the bottom of the housing 10, and at least one drain hole 12 is formed in the support surface 111. The drain valve 20 is arranged at the drain hole 12. The drain valve 20 includes a movable opening and closing member 21, and at least a part of the opening and closing member 21 penetrates through the drain hole 12. When a part of the opening and closing member 21 extends from the support surface 111 out of the housing 10, as Figure 4 shown, the drain hole 12 is closed; when the opening and closing member 21 retracts into the housing 10, as Figure 5 shown, the drain hole 12 is opened. In this way, the drain hole 12 can be opened and closed by the movement of the opening and closing member 21. When picking up the cooking appliance for cleaning, moving the opening and closing member 21 to the closed position can prevent water from entering at the drain hole 12, thus avoiding the problem of water backflow at the drain hole 12 during cleaning. When the cooking appliance is placed on the tabletop, the support surface 111 is in contact with the tabletop, so that the tabletop can press the opening and closing member 21 into the housing 10. At this time, the drain hole 12 is opened, and the water in the housing 10 can be drained in time.

[0039] In one embodiment, the drain valve 20 further includes an elastic member 22 which acts on the opening and closing member 21 to enable the opening and closing member 21 to move to a position closing the drain hole 12. In this way, when picking up the cooking appliance for cleaning, under the elastic force of the elastic member 22, the opening and closing member 21 moves towards the position closing the drain hole 12, thus closing the drain hole 12. When in use, when the cooking appliance is placed on the tabletop, as long as the elastic force of the elastic member 22 is less than the gravity of the cooking appliance, the tabletop can push the opening and closing member 21 to retract the opening and closing member 21 into the housing 10, so that the drain hole 12 is opened. It can be seen that in this embodiment, by providing the elastic member 22, during normal use, the drain hole 12 is opened for normal drainage, while when picking up the cooking appliance for cleaning, the elastic force of the elastic member 22 can cause the opening and closing member 21 to move to automatically close the drain hole 12, thus avoiding the problem that the drain hole 12 is in an open state during cleaning due to forgetting to move the opening and closing member 21 or the gravity of the opening and closing member 21 being unable to move the opening and closing member 21 to the closed position.

[0040] Of course, in other embodiments, it may also be manual control of the movement of the opening and closing member. For example, a push button is connected to the opening and closing member, and the position movement control of the opening and closing member is achieved through the push button.

[0041] Please refer to Figures 2 to 5 Furthermore, the drain valve 20 further includes a pressing plate 23 which is fixed inside the housing 10. The elastic member 22 abuts between the pressing plate 23 and the opening and closing member 21, providing a force for the opening and closing member 21 to move towards the closing position of the drain hole 12. In this way, a space for installing the elastic member 22 is formed between the pressing plate 23 and the opening and closing member 21, with a simple structure and easy installation of the elastic member 22.

[0042] In this embodiment, the elastic member 22 is a compression spring, with a simple structure and easy installation.

[0043] Furthermore, a limiting post 231 is provided on one side of the pressing plate 23. One end of the elastic member 22 is sleeved outside the limiting post 231 and abuts against the pressing plate 23. In this way, the elastic member 22 can be limited to prevent it from falling off.

[0044] Furthermore, the pressing plate 23 can be fixedly installed inside the housing 10 through fasteners. Specifically, an installation post 13 is provided inside the housing 10. The inner cavity of the installation post 13 is communicated with the drain hole 12, and through holes can be provided on the side wall of the installation post 13 to communicate the inner cavity of the housing 10 and the inner cavity of the installation post 13, so that the water inside the housing 10 can flow into the inner cavity of the installation post 13 through the through holes and finally be discharged through the drain hole 12. However, it is not limited to this. In other embodiments, there may also be a bracket inside the housing, and the pressing plate is installed on the bracket through fasteners. Of course, the pressing plate can also be fixed inside the housing in other ways, as long as the installation of the pressing plate does not affect the discharge of water inside the housing through the drain hole. In addition, the pressing plate can also be integrally formed with the housing.

[0045] Further, the opening and closing member 21 includes a trigger rod 211 and a sealing member 212. The trigger rod 211 passes through the drain hole 12, and the sealing member 212 is connected to the outer wall of the trigger rod 211 and is located inside the housing 10. When a part of the trigger rod 211 extends out of the support surface 111 and the sealing member 212 abuts against one end of the drain hole 12, the drain hole 12 is closed; when the trigger rod 211 retracts into the housing 10 and the sealing member 212 moves away from the drain hole 12, the drain hole 12 is opened. In this way, the structure of the opening and closing member 21 is very simple. By pushing the trigger rod 211 to move, the movement of the sealing member 212 can be controlled, so as to open or close the drain hole 12.

[0046] Further, a limiting rib 213 is provided on the trigger rod 211. The opening and closing member 21 further includes a stopper 214. The sealing member 212 and the stopper 214 are sequentially sleeved on the outer side of the trigger rod 211, and the sealing member 212 is clamped between the limiting rib 213 and the stopper 214. In this way, by providing the limiting rib 213 and the stopper 214, it is convenient to connect the sealing member 212 to the trigger rod 211, and the connection between the sealing member 212 and the trigger rod 211 is firm. Further, the stopper 214 can be set as a nut, an external thread is provided on the trigger rod 211, and the stopper 214 is in threaded fit with the trigger rod 211. However, it is not limited thereto. The stopper can also be set as a snap ring, a slot is provided on the trigger rod, and the snap ring is clamped in the slot, which can also limit the movement of the sealing member, so as to install the sealing member on the trigger rod. In this embodiment, the elastic member 22 is a spring. One end of the elastic member 22 is sleeved on the outer side of the trigger rod 211 and abuts against the stopper 214. In this way, the trigger rod 211 can limit the elastic member 22 to prevent the elastic member 22 from falling off.

[0047] Of course, in other embodiments, the sealing member can also be integrally formed on the outer wall of the trigger rod. In this way, the limiting rib and the stopper can be not provided on the trigger rod, and the structure is simpler. Further, one end of the elastic member sleeved on the outer side of the trigger rod can abut against the sealing member.

[0048] Further, the sealing member 212 is a silica gel part, and the sealing effect is good.

[0049] Further, when the drain hole 12 is closed, the length of the trigger rod 211 extending out of the support surface 111 is L, and L is 2 mm to 5 mm. In this way, when the cooking appliance is placed on the tabletop, the trigger rod 211 will be squeezed by the tabletop and move 2 mm to 5 mm, so as to ensure that there is enough clearance between the sealing member 212 and the end face of the drain hole 12, and ensure that the water in the housing 10 can be smoothly discharged through the drain hole 12.

[0050] In this embodiment, as shown in the figure, feet 11 are provided at the bottom of the outer shell 10, and the end face of the feet 11 constitutes a supporting surface 111. By providing the feet 11 at the bottom of the outer shell 10, there is a certain gap between the bottom surface of the outer shell 10 and the tabletop when the cooking appliance is placed on the tabletop, which is beneficial to the heat dissipation at the bottom of the cooking appliance. Of course, in other embodiments, the feet may not be provided at the bottom of the outer shell, and the part where the lowest point of the outer shell contacts the tabletop constitutes the supporting surface.

[0051] It can be understood that when the cooking appliance is placed on a flat surface, the flat surface will squeeze the opening and closing member 21 to open the drain hole 12. Therefore, when cleaning the cooking appliance provided in the present application, the supporting surface 111 provided with the drain hole 12 cannot contact the bottom wall of the sink, so as to prevent the bottom wall of the sink from pressing the opening and closing member 21 to open the drain hole 12 and cause water to pour back into the outer shell 10 of the cooking appliance.

[0052] The cooking appliance provided in the present application can be a wok, a frying pan, a small milk pan, a small boiling pan, a small stewing pan, etc. For cooking appliances such as a wok, a frying pan, and a small milk pan, the user can directly hold the cooking appliance for cleaning, thus avoiding the situation where the opening and closing member 21 is pressed by the bottom wall of the sink to open the drain hole 12. Among them, for cooking appliances such as a wok, a frying pan, and a small milk pan, a rod-shaped handle 300 is usually further included. As Figure 1 shown, for such cooking appliances, the drain hole 12 can be provided only at a position of the supporting surface 111 close to the handle 300. Thus, even when the cooking appliance is placed in the sink for cleaning, the supporting surface 111 provided with the drain hole 12 will not contact the bottom wall of the sink, thereby avoiding the situation where the opening and closing member 21 is pressed by the bottom wall of the sink to open the drain hole 12.

[0053] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0054] The above-described embodiments only represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
