Description

Pot cover assembly and cooking utensil with same

Technical Field

The invention relates to the technical field of small household appliances, in particular to a pot cover assembly and a cooking appliance with the same.

Background

The electric pressure cooker is a common household appliance. The existing electric pressure cooker has a quick cooking function, and the principle of the electric pressure cooker is that the cooking temperature is improved and the cooking time is shortened by hermetically pressurizing a cooking cavity. However, after the pressure cooking operation is finished, because the pressure in the cooker is higher than the atmospheric pressure, a user cannot open the cover immediately to take out food, especially soup, fluid or viscous food, and because the user cannot directly deflate the cooker to quickly cool the cooker (the direct deflation can cause the food to overflow), the natural cooling needs a long waiting time. For example, when a user cooks porridge for about 35 minutes, the natural cooling time of the electric pressure cooker is as long as 25 minutes, so that the whole cooking time is long, and the user experience is poor.

In addition, when some foods are cooked under pressure, the calculated pressure cooking time does not calculate the additional time generated in the pressure drop process of the electric cooker, so that the actual pressure cooking time of the foods is longer than the cooking time set by a user, and the slow pressure relief of the pressure cooker can influence the taste of the foods. Therefore, how to realize the quick cooling and pressure relief after cooking and enable a user to open the cover quickly is a problem to be solved urgently in the electric pressure cooker product.

In order to solve the above problems, some electric pressure cookers in the prior art have a cooling structure, for example, a heat dissipation cover is provided in the lid. However, since there are gaps between the structures in the lid after assembly, the air flow blown from the outside partially flows into the gaps and cannot enter the heat dissipation cover, thereby making the heat dissipation effect worse.

Furthermore, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, 2, 6, 7, 9 and 10, the pot cover assembly of the present embodiment includes an inner cover 10, a heat sink 20 and an air duct connecting plate 30. Wherein, the inner lid 10 is provided with a first air inlet 11. The heat sink 20 includes a heat dissipation cover 22, and a second air inlet 221 is provided on the heat dissipation cover 22. The air duct connecting plate 30 is disposed between the inner lid 10 and the heat sink 20, the air duct connecting plate 30 includes an air duct 31, and both ends of the air duct 31 communicate with the first air inlet 11 and the second air inlet 221.

With the technical solution of the present embodiment, an air duct connecting plate 30 is disposed between the inner cover 10 and the heat sink 20. A closed channel is formed between the first air inlet 11 and the second air inlet 221 through the air duct 31 of the air duct connecting plate 30, and cold air entering from the first air inlet 11 can completely enter the heat dissipation cavity through the air duct 31 and the second air inlet 221, so that the cooling effect is ensured. Therefore, the technical scheme of the embodiment overcomes the defect of poor heat dissipation and cooling effects of the middle cover of the electric pressure cooker in the prior art.

Further, the heat sink 20 in this embodiment is rotatably disposed below the inner cover 10, and the heat sink 20 further includes a locking cover body 21. The heat dissipation cover 22 covers the lock cover body 21, and the lock cover body 21 and the heat dissipation cover 22 enclose a heat dissipation cavity. That is, the lock cover body 21 and the heat dissipation cover 22 in the present embodiment also constitute a lock cover assembly.

It should be noted that, the lower edge of the locking cover body 21 of the heat sink 20 is provided with cover teeth, and the pot body of the cooking appliance is provided with pot teeth. The user can rotate the heat sink 20 by turning a handle (not shown) so that the cover teeth and the pot teeth are locked to or separated from each other, i.e., to switch the heat sink 20 between the locked position and the unlocked position.

In addition, the heat sink 20 further includes fins 23, and the fins 23 are disposed in the heat dissipation chamber. Specifically, after entering from the first air inlet 11, the external cold air enters the heat dissipation chamber through the air duct 31 and the second air inlet 221. After the external cold air flows through the fins 23, the temperature of the fins 23 can be reduced, so that continuous heat exchange and temperature reduction of the locking cover body 21 are realized.

As shown in fig. 7 and 8, in the solution of this embodiment, the lid assembly further includes an elastic member 40. The elastic member 40 is disposed between the inner cover 10 and the heat sink 20, and the elastic member 40 is adapted to apply an elastic force to the air duct connection plate 30 toward the inner cover 10 or to apply an elastic force to the air duct connection plate 30 toward the heat sink 20. In this embodiment, the air duct connecting plate 30 is tightly attached to the heat dissipating device 20 and the inner cover 10 by the elastic member 40, so that the cold air entering from the first air inlet 11 can completely enter the heat dissipating cover 22 through the air duct connecting plate 30.

In this embodiment, the elastic member 40 is disposed between the air duct connecting plate 30 and the inner surface of the inner cover 10, so that when the heat sink 20 rotates, the air duct connecting plate 30 is always tightly attached to the outer surface of the heat sink 22 by the elastic force exerted by the elastic member 40. Of course, in some ways not shown, the elastic member 40 may be disposed between the air duct connection plate 30 and the heat dissipation cover 22.

As can be seen from fig. 1 and 4, the inner cap 10 is in a cap-like structure, and when assembled, a plastic cap (not shown) is required to be assembled outside the inner cap 10. The first air inlet 11 is provided at a side portion of the rear side of the inner lid 10, and the first air inlet 11 is substantially a square opening.

As can be seen from fig. 3, the heat sink 20 of the present embodiment includes three structures, namely, a locking cover body 21, a heat dissipation cover 22, and fins 23. The heat dissipation cover 22 is in a cover-shaped structure, and the heat dissipation cover 22 is covered on the lock cover body 21. The heat dissipation cover 22 and the lock cover body 21 enclose a cavity, i.e. a heat dissipation cavity. The fins 23 are multiple, and the multiple fins 23 are in an integrated annular structure and are placed in the heat dissipation cavity. The second air inlet 221 is provided on the side wall of the heat dissipation cover 22, and when the heat sink 20 is in the unlock position, the second air inlet 221 corresponds to the first air inlet 11.

The second air inlet 221 is sized to fit the first air inlet 11 and is also square.

As shown in fig. 6 and 7, the air duct connecting plate 30 in the present embodiment is plate-shaped and is a square plate. Further, since the side wall of the heat dissipation cover 22 and the inner side surface of the inner cover 10 are arc-shaped surfaces, the air duct connecting plate 30 is also arc-shaped. The air duct 31 is formed by an annular surrounding rib, the annular surrounding rib protrudes out of the surface of the air duct connecting plate 30, and the inside of the annular surrounding rib is hollow, so that the air duct 31 is formed. Those skilled in the art will understand that the thickness of the annular rib may be determined according to the distance between the first air inlet 11 and the second air inlet 221, and two ends of the annular rib are respectively communicated with the first air inlet 11 and the second air inlet.

As shown in fig. 4, 5, 7 and 8, in the solution of the present embodiment, a guide groove 12 is provided at a side portion of the first air inlet 11, and a connection column 32 is provided on the air duct connection plate 30. The connection post 32 is inserted into the guide groove 12, and the elastic member 40 is disposed between the inner lid 10 and the air duct connection plate 30.

Specifically, the guide groove 12 is provided on the inner side surface of the inner lid 10, and extends toward the wall thickness direction of the inner lid 10. The connecting column 32 is arranged on the surface of the air duct connecting plate 30 facing the first air inlet 11, and the connecting column 32 is arranged in the guide groove 12 in a penetrating manner, so that the moving direction of the air duct connecting plate 30 can be guided. Those skilled in the art will appreciate that the guide slots 12 and the connecting posts 32 allow the air duct connecting plate 30 to move in a direction toward or away from the heat sink 22.

As can be seen from fig. 4 and 7, two guide grooves 12 are correspondingly disposed, and the two guide grooves 12 are respectively located at two sides of the first air inlet 11. Correspondingly, the connecting columns 32 are also arranged into two groups, and the two groups of connecting columns 32 are respectively positioned at two sides of the air duct 31. The above structure can ensure the motion stability of the air duct connecting plate 30.

As can be seen from fig. 7, the elastic member 40 is disposed between the air duct connecting plate 30 and the inner side surface of the inner cover 10, so that the elastic member 40 can provide an elastic force towards the heat dissipation cover 22 to the air duct connecting plate 30, so that the air duct connecting plate 30 is always tightly attached to the heat dissipation cover 22, and a closed passage is ensured between the first air inlet 11 and the second air inlet 221.

Of course, in some embodiments, not shown, the above-mentioned guide groove 12 may also be disposed on the side surface of the heat dissipation cover 22, and correspondingly, the connection pole 32 is disposed on the surface of the air duct connection plate 30 facing the second air inlet 221, and the elastic member 40 is disposed between the heat dissipation cover 22 and the air duct connection plate 30. This configuration is also a possible implementation.

As shown in fig. 5 and 8, in the technical solution of the present embodiment, a hook 321 is disposed on the connecting column 32, a slot 121 is disposed on the side wall of the guide slot 12, and the hook 321 is clamped in the slot 121. Specifically, when the connector post 32 is inserted into the guide groove 12 during assembly, the hook 321 is engaged with the engaging groove 121. The clamping groove 121 can limit the air duct connecting plate 30, and the clamping hook 321 is prevented from being separated from the clamping groove 121.

Preferably, the elastic member 40 is a spring, one end of the spring abuts against the air duct connecting plate 30, and the other end of the spring penetrates through the guide groove 12. Specifically, the spring is in contact with the bottom of the guide groove 12 and is in a compressed state, and further, the spring can apply an elastic force to the air duct connecting plate 30.

Further, the number of the springs is two, the two springs are respectively located at two sides of the air duct 31, and the two springs are respectively arranged in the guide grooves 12 in a penetrating manner.

As shown in fig. 8, in the technical solution of the present embodiment, the air duct connecting plate 30 is provided with two guide posts 33, the two connecting posts 32 are provided, the guide posts 33 are located between the two connecting posts 32, and the spring is inserted into the guide posts 33. Specifically, the guide posts 33 facilitate assembly of the spring. Two guide posts 33 are disposed on both sides of the air duct 31 of the air duct connecting plate 30 (i.e. four guide posts 33 are disposed on the air duct connecting plate 30). Taking one side of the air duct 31 as an example, the connecting posts 32 are disposed oppositely, and the hooks 321 are disposed on both of the connecting posts 32. The hooks 321 of the two connecting posts 32 are away from each other, and correspondingly, the two opposite sidewalls of the guiding slot 12 are respectively provided with a locking slot 121.

As shown in fig. 6 and 7, in the present embodiment, a plurality of air deflectors 311 are provided in the air duct 31. The air deflector is used for conducting flow guiding balance on cold air entering from the first air inlet 11, so that the flowing direction of air flow is more uniform, and the heat dissipation effect is better.

Preferably, the air guide plate 311 is obliquely arranged. Specifically, the end of the air deflector 311 facing the second air inlet 221 is inclined outward, so as to provide a diffusion and flow equalization effect for the air flow.

As shown in fig. 1, in the technical solution of the present embodiment, a connecting pipe 50 is disposed at the first air inlet 11, and the connecting pipe 50 is suitable for being connected with an air outlet of a fan. Since the lid needs to be opened and closed with respect to the pot body, the connection pipe 50 is preferably selected as a hose.

The embodiment also provides a cooking appliance, which comprises the pot cover assembly.

Preferably, the cooking appliance is an electric pressure cooker, the electric pressure cooker comprises a cooker body and a cooker cover, and the cooker cover comprises the cooker cover assembly.

Further, the user can drive the heat sink 20 to rotate by turning a handle (not shown), so that the cover teeth and the pot teeth are locked or separated from each other, i.e., the heat sink 20 is driven to switch between the locked position and the unlocked position. When the heat sink 20 is in the locked position, the first air inlet 11 and the second air inlet 221 are aligned and form a closed passage therebetween through the air duct 31 of the air duct connecting plate 30. When the heat dissipation device is located at the unlocking position, the first air inlet 11 and the second air inlet 221 are dislocated, but at this time, the user usually performs the operation of opening the cover, or the electric pressure cooker is in the uncooked state, so the blower fan cannot be started, that is, the dislocation of the first air inlet and the second air inlet does not affect the normal use of the electric pressure cooker.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
