Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen utensils, in particular to a pot cover structure and a cooking utensil provided with the same. BACKGROUND

[0002] At present, most cooking utensils will generate steam during cooking. The steam will condense after contacting the upper cover of the cooking utensil, resulting in a large amount of condensed water accumulated on the upper cover. The condensed water not only falls on the food, affecting the taste of the food, but also drips onto the table when the cover is opened, causing unnecessary trouble.

[0003] In related technologies, a thermal insulation coating is usually added to the upper cover to achieve a thermal insulation effect, thereby reducing the low-temperature influence of the external environment on the pot cover and reducing the condensed water accumulated on the pot cover. However, over time, the thermal insulation performance of the thermal insulation coating gradually decreases. Moreover, due to the complex production process of the thermal insulation coating and the high cost of raw materials, the overall cost is high. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide a pot cover structure that reduces the amount of condensed water directly dripping onto the food or the table in the cooking cavity by using the arrangement of a thermal insulation cavity, effectively ensures the cooking effect of the food, and improves the use experience. Moreover, the pot cover structure is easy to manufacture, reduces the manufacturing cost, and prolongs the service life.

[0005] A pot cover structure for a cooking utensil includes an upper cover and a lower cover. The upper cover and the lower cover are detachably connected and jointly surround a thermal insulation cavity. The lower cover is provided with an air inlet channel, and the upper cover is provided with an air outlet channel. The air inlet channel and the air outlet channel are both connected to the thermal insulation cavity and are arranged staggeredly.

[0006] It can be understood that the arrangement of the thermal insulation cavity is equivalent to adding an air thermal insulation layer between the upper cover and the lower cover. The steam entering the thermal insulation cavity can first fill the thermal insulation cavity, thereby reducing the temperature difference between the lower cover and the cooking cavity and reducing the condensation amount of the steam on the lower cover. Moreover, although the upper cover is in contact with the external environment, causing the steam to condense on the upper cover. At this time, the condensed water is stored in the thermal insulation cavity, avoiding direct dripping onto the food, and also not flowing out when the cover is opened. In this way, the amount of condensed water directly dripping from the pot cover structure to the food is reduced, effectively ensuring the cooking effect of the food; and the amount of condensed water dripping onto the table after the cover is opened is reduced. At the same time, due to the detachable connection of the upper cover and the lower cover, the two can be detached for cleaning to remove the condensed water in the thermal insulation cavity, and the upper cover and the lower cover can be easily cleaned and dried, reducing the risk of bacterial growth due to delayed cleaning of the condensed water.

[0007] In some embodiments, the lower cover is provided with an arch portion and a water storage groove, the arch portion is arched towards the upper cover, the water storage groove is arranged on the outer circumferential side of the arch portion or on the edge close to the arch portion, and the air inlet channel is arranged on the arch portion.

[0008] That is, the arch portion is used to guide the condensed water dropped from the upper cover to flow naturally to the water storage groove, which is beneficial to the collection of the condensed water.

[0009] In some embodiments, the lower cover is provided with a rib close to the edge, the rib extends along the circumference of the lower cover, and the rib and the upper surface of the lower cover jointly define the water storage groove. The rib is used to form the water storage groove in cooperation with the lower cover, which is simple in structure, does not need to be additionally provided with other structures, and reduces the weight of the pot cover structure itself.

[0010] In some embodiments, one of the upper cover and the lower cover is provided with a clamping arm, and the other is provided with a clamping groove, the clamping arm is inserted into the clamping groove to be clamped and matched. In this way, the detachable connection of the upper cover and the lower cover can be achieved.

[0011] In some embodiments, the clamping arm has a deformation portion and a clamping portion connected to the deformation portion, the deformation portion is connected to one of the upper cover and the lower cover, and the clamping portion is clamped and matched with the other. That is, the deformation portion is used to facilitate the movement of the clamping arm relative to the clamping groove, which is convenient to operate.

[0012] In some embodiments, the clamping arm includes a first arm body and a second arm body connected to the first arm body, the two are arranged at an angle and are circularly arcuate, the circular arc transition forms the deformation portion, and an end of the second arm body away from the first arm body forms the clamping portion.

[0013] That is, the first arm body and the second arm body can be close to each other under the action of an external force at this time, and the deformation portion is bent; and after the external force is removed, the deformation portion has a restoring force to promote the first arm body and the second arm body to have a movement trend of moving away from each other, which improves the connection reliability.

[0014] In some embodiments, the clamping arm further includes a force applying portion, the force applying portion is connected to the second arm body, and an operator can hold the force applying portion to release the clamping and matching of the clamping arm and the clamping groove.

[0015] In some embodiments, the pot cover structure further includes a sealing member, the sealing member is pressed between the upper cover and the lower cover; the sealing member is annularly arranged, one side of the sealing member is provided with a fitting groove, and the other side is provided with an abutting arm; one of the upper cover and the lower cover is provided with a fitting strip, and the other is provided with an abutting protrusion, the fitting strip is inserted into the fitting groove, and the abutting protrusion is pressed on the abutting arm.

[0016] Such a setting ensures that the sealing performance of the heat preservation cavity is good in all directions, especially not easy to leak water during use, improving the use safety. At the same time, on the one hand, the detachable connection of the sealing element is met, and the connection reliability is ensured to realize sealing; on the other hand, the setting of the abutting protrusion increases the force on the sealing element, further improving the sealing performance.

[0017] In some embodiments, the upper cover is provided with a first enclosing part, the lower cover is provided with a second enclosing part, the first enclosing part is enclosed outside the second enclosing part, and a gap communicating with the heat preservation cavity and a water storage cavity communicating with the gap are arranged between the first enclosing part and the second enclosing part.

[0018] That is, the condensed water generated by the temperature difference at the upper cover flows into the water storage cavity through the gap, and is drained away from the heat preservation cavity, reducing the influence of the condensed water on the heat preservation cavity.

[0019] In some embodiments, the air outlet channel and the air inlet channel are arranged on opposite sides of the central axis of the heat preservation cavity.

[0020] Such a setting is equivalent to extending the flow path of the steam entering the air outlet channel through the air inlet channel, ensuring that the steam can fully fill the heat preservation cavity to achieve the heat preservation effect on the lower cover, thereby isolating the external environment from the cooking cavity and reducing the temperature difference.

[0021] The application also provides a cooking utensil comprising a pot body and the above-mentioned pot cover structure, and the pot cover structure is connected to the pot body. The cooking utensil has the technical effects of any one of the above-mentioned embodiments. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0033] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a variety of ways beyond the specific embodiments described herein without departing from the scope of the present application, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0034] It is to be noted that when a component is referred to as being "on" or "disposed on" another component, it can be directly on the other component or intervening components can also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components can also be present. The terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar terms as used in the description of the present application are for the purpose of illustration only and do not indicate the only position of the device.

[0035] In addition, the terms "first", "second", etc. are used herein only to describe various conditions, and are not to be construed as indicating relative importance or a required order of steps. Thus, features defined with "first", "second" etc. can include at least one of the features, explicitly or implicitly.

[0036] In the present application, unless otherwise explicitly specified and limited, "on", "under", "above", and "over" of a first feature to a second feature can mean that the first feature is in direct contact with the second feature, or the first feature is in indirect contact with the second feature through an intermediate medium. Moreover, "above", "over", and "on" of a first feature to a second feature can mean that the first feature is directly above or obliquely above the second feature, or only means that the first feature is horizontally higher than the second feature. "Below", "under", and "under" of a first feature to a second feature can mean that the first feature is directly below or obliquely below the second feature, or only means that the first feature is horizontally lower than the second feature.

[0037] Unless otherwise defined, all technical and scientific terms used in the specification of the present application have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more related listed items.

[0038] At present, some cooking utensils will produce water vapor during cooking, for example, a steamer. The steamer mainly uses a heater at the bottom of a pot body to heat water in the pot body, so as to make the water boil to generate steam, and then uses the heat of the steam to heat food materials to meet the cooking of the food materials. The steam cover of the steamer is provided with an exhaust hole, which is beneficial to the exhaust of excess steam in the cooking cavity from the exhaust hole, so as to ensure that the pressure in the cooking cavity is not too large to lift the cover or cause other safety hazards.

[0039] Since the outer surface of the pot cover is in contact with the external environment, there is a large temperature difference between the external environment and the cooking cavity, and there is also a large temperature difference between the inner surface of the pot cover and the steam in the cooking cavity; that is, the temperature of the external environment is less than the temperature in the cooking cavity, and the temperature of the inner surface of the pot cover is less than the temperature of the steam in the cooking cavity due to the influence of the external environment. Therefore, when the steam rises to contact the pot cover, condensation will occur, and these condensate water will accumulate and drip onto the food in the cooking cavity during cooking, thereby affecting the taste of the food. Moreover, after cooking is completed, a large amount of condensate water condensed on the pot cover is extremely easy to flow onto the countertop when the cover is opened, causing unnecessary trouble.

[0040] In related technologies, a heat preservation coating is added to the pot cover to achieve a heat preservation effect, thereby reducing the low temperature influence of the external environment on the pot cover and reducing the condensate water accumulated on the pot cover. However, over time, the heat preservation performance of the heat preservation coating will gradually decrease. Moreover, due to the complex production process of the heat preservation coating and the high cost of raw materials, the overall cost is relatively high.

[0041] To this end, an embodiment of the present application provides a pot cover structure for a cooking appliance, which utilizes the arrangement of a heat preservation cavity to reduce the amount of condensate water that directly drips onto the food in the cooking cavity or the countertop, effectively ensuring the cooking effect of the food and improving the user experience. Moreover, the pot cover structure is easy to manufacture, reduces manufacturing costs, and prolongs the service life. The pot cover structure is described in detail below.

[0042] Please refer to Figure 1 and Figure 2 , for example, the pot cover structure 100 includes an upper cover 110 and a lower cover 120, which are detachably connected and collectively surround a heat preservation cavity 101. The lower cover 120 is provided with an air inlet passage 102, and the upper cover 110 is provided with an air outlet passage 103. The air inlet passage 102 and the air outlet passage 103 are both connected to the heat preservation cavity 101 and are arranged staggered. When the pot cover structure 100 is in use, one of the upper cover 110 and the lower cover 120 provided with the air inlet passage 102 faces the cooking cavity, and the other provided with the air outlet passage 103 faces away from the cooking cavity. The water vapor in the cooking cavity rises to the heat preservation cavity 101 through the air inlet passage 102, and then flows out from the air outlet passage 103, to ensure that the pressure inside and outside the cooking cavity is maintained safely.

[0043] The presence of the heat-insulating cavity 101 effectively adds an air insulation layer between the upper cover 110 and the lower cover 120. Steam entering the heat-insulating cavity 101 can preferentially fill it, thus reducing the impact of the lower cover 120 on the low temperature of the external environment. In other words, it reduces the temperature difference between the lower cover 120 and the cooking cavity, thereby reducing the amount of steam condensing on the lower cover 120. Furthermore, although the upper cover 110 is in contact with the external environment, creating a significant temperature difference between the heat-insulating cavity 101 and the external environment, causing steam to condense at the upper cover 110, this condensate is stored within the heat-insulating cavity 101, preventing it from dripping directly onto the food and preventing it from flowing out when the lid is opened. Thus, on the one hand, it reduces the amount of condensate dripping directly from the lid structure 100 onto the food, effectively ensuring the cooking effect; on the other hand, it reduces the amount of condensate dripping onto the countertop after the lid is opened. Meanwhile, due to the detachable connection between the upper cover 110 and the lower cover 120, they can be disassembled during cleaning to remove condensate in the insulation cavity 101 and facilitate cleaning and drying of the upper cover 110 and the lower cover 120, reducing the risk of bacteria growth due to untimely cleaning of condensate.

[0044] In actual use, the air inlet channel 102 and the air outlet channel 103 are arranged on opposite sides of the central axis of the insulation cavity 101. For example... Figure 1 As shown, Z is the central axis. Taking the left-right direction as an example, when the air inlet channel 102 is located on the right, the air outlet channel 103 is located on the left; as another example, when the air inlet channel 102 is located in the lower left corner, the air outlet channel 103 is located in the upper right corner. This arrangement is equivalent to extending the flow path of steam from the air inlet channel 102 to the air outlet channel 103, ensuring that steam can fully fill the insulation cavity 101, thereby improving the insulation effect on the lower cover 120, and thus isolating the external environment from the cooking cavity and reducing the temperature difference.

[0045] Furthermore, the exhaust channel 103 is located near the edge of the insulation cavity 101, which maximizes the path of steam flow from the intake channel 102 to the exhaust channel 103. Alternatively, the intake channel 102 can also be located near the edge of the insulation cavity 101. This ensures the maximum distance between the intake channel 102 and the exhaust channel 103, further enhancing the uniform diffusion of steam within the insulation cavity 101.

[0046] In this design, the lid structure 100 is rectangular, so the projection of the corresponding insulation cavity 101 along its central axis is also rectangular. The air inlet channel 102 and the air outlet channel 103 can be located on opposite sides along the length; alternatively, they can be located on opposite sides of a vertical angle, or on opposite sides along the width. The only requirement is that they ensure uniform steam diffusion within the insulation cavity 101 to guarantee the insulation effect. This is merely an example.

[0047] Further, the cross section of the outlet passage 103 is not greater than the cross section of the inlet passage 102. In other words, the flow rate of steam entering the inlet passage 102 is greater than the flow rate of steam flowing out of the outlet passage 103. Such an arrangement can ensure that the steam in the heat preservation cavity 101 can contact the lower cover 120 as much as possible, thereby improving the heat preservation effect.

[0048] In some specific embodiments, the lower cover 120 is provided with a second through hole penetrating in the thickness direction of the lower cover 120, and the second through hole forms the inlet passage 102. Such an arrangement does not need to add other guide pipeline structures, thereby simplifying the structure and facilitating manufacturing. The second through hole is in the form of a long hole. The long hole can obtain a large flow area with a small number of control, thereby increasing the flow rate into the heat preservation cavity 101. The upper cover 110 is provided with a first through hole penetrating in the thickness direction of the upper cover 110, and the first through hole forms the outlet passage 103. The first through hole is also in the form of a long hole.

[0049] Please refer to Figures 1 to 3 Optionally, the lower cover 120 is provided with an arch portion 104, and the arch portion 104 is arched towards the upper cover 110, and the inlet passage 102 is arranged in the arch portion 104. In other words, the specific arrangement of the arch portion 104 causes the lower cover 120 to form a flow guide slope for guiding the flow of condensed water. When condensed water is generated on the side of the upper cover 110 facing the lower cover 120, the condensed water drops onto the upper surface of the lower cover 120 and is guided to a position close to the side of the pot cover structure 100 by the arch portion 104, thereby avoiding the condensed water from gathering at a position close to the middle of the lower cover 120 and reducing the temperature difference between the two sides of the lower cover 120 in the thickness direction, thereby further reducing the condensed water generated by the lower cover 120. Moreover, since the inlet passage 102 is arranged in the arch portion 104, when steam flows into the heat preservation cavity 101 from the inlet passage 102, the flow area changes, and part of the flow area increases and part of the flow area first decreases and then increases. When the flow area increases, the steam flow rate can be reduced, thereby ensuring that the steam can fully contact the lower cover 120, and thereby enhancing the heat preservation effect. When the flow area first decreases and then increases, the heat loss during the steam flow can be reduced, thereby ensuring that more heat can be directly transmitted to the lower cover 120, and thereby further improving the heat preservation effect.

[0050] Please refer to Figures 2 to 4In some embodiments, the lower cover 120 is provided with a water storage groove 105 on one side thereof facing the upper cover 110, which is arranged on the outer circumferential side of the arch portion 104 or near the edge of the arch portion 104. The condensed water guided from the arch portion 104 can flow to the water storage groove 105, which is conducive to collecting the condensed water. Specifically, the position near the edge of the lower cover 120 is provided with a rib 121 protruding therefrom, which extends along the circumference of the lower cover 120 to be arranged around the heat preservation cavity 101. The rib 121 and the upper surface of the lower cover 120 together form the water storage groove 105. The rib 121 can be linearly arranged to form the water storage groove 105 with the lower cover 120, which has an L-shaped or V-shaped cross section. Of course, the rib 121 can also be arranged in an L shape to form the water storage groove 105 with the lower cover 120, which has a "C" shaped cross section. Here, only an example is given. It can be understood that the rib 121 is protruding to cooperate with the lower cover 120 to form the water storage groove 105, which has a simple structure and does not need to be additionally provided with other structures, thereby reducing the weight of the pot cover structure 100 itself.

[0051] In some embodiments, the upper cover 110 can also be downwardly inclined on one side thereof facing the heat preservation cavity 101, which is conducive to the condensed water on the upper cover 110 to flow to the water storage groove 105.

[0052] Please refer to Figure 1 and Figure 2 As some embodiments, the pot cover structure 100 further comprises a sealing member 140, which is arranged between the upper cover 110 and the lower cover 120 and is annularly arranged. Such an arrangement ensures good sealing performance of the heat preservation cavity 101 in all directions, especially in use, which is not easy to leak water and improves the safety in use. The sealing member 140 can be a silica gel sealing gasket, a rubber sealing gasket, etc. The sealing member 140 is arranged around the outer circumferential side of the water storage groove 105, which ensures good sealing performance of the heat preservation cavity 101 and reduces the amount of water leakage.

[0053] In some specific embodiments, the sealing member 140 is detachably connected between the upper cover 110 and the lower cover 120, facilitating the cleaning of the sealing member 140 after being detached to reduce bacterial growth. For example, one of the upper cover 110 and the lower cover 120 is snap-fitted with the sealing member 140, and the other is abutted with the sealing member 140 to achieve the limiting assembly and detachable connection of the sealing member 140. Specifically, the rib 121 on the lower cover 120 is provided with an assembly bar 151, and the sealing member 140 is provided with an assembly groove 141, the assembly bar 151 is inserted into the assembly groove 141 to achieve the connection of the sealing member 140 relative to the lower cover 120. The side of the upper cover 110 facing the lower cover 120 is provided with an abutting protrusion 152, and the other side of the sealing member 140 is provided with an abutting arm 142, which is abutted to the abutting protrusion 152. In this way, not only the detachable connection of the sealing member 140 is satisfied, but also the connection reliability is ensured to achieve sealing; and by using the abutting protrusion 152, the acting force on the sealing member 140 is increased to further improve the sealing performance. Alternatively, after the sealing member 140 is fixed relative to the lower cover 120 through the assembly groove 141, it can be pressed between the upper cover 110 and the lower cover 120 by connecting them.

[0054] Alternatively, the sealing member 140 can be provided with assembly grooves 141 on both sides along the width direction thereof, and the upper cover 110 and the lower cover 120 can be provided with assembly bars 151, each of which is inserted into the corresponding assembly groove 141. Alternatively, the upper cover 110 is provided with an assembly bar 151, and the side of the lower cover 120 facing the upper cover 110 is provided with an abutting protrusion 152 to achieve the detachable connection and pressing of the sealing member 140. This is only an example.

[0055] Alternatively, the sealing member 140 is adhesively fixed with the upper cover 110 and is snap-fitted or abutted with the lower cover 120. While satisfying the sealing, the detachable connection of the upper cover 110 and the lower cover 120 is achieved to facilitate the discharge and cleaning of the condensed water.

[0056] Please refer to Figure 2 and Figure 4 Alternatively, one of the upper cover 110 and the lower cover 120 is provided with a snap arm 131, and the other is provided with a clamping groove 132, the snap arm 131 is snap-fitted with the clamping groove 132 to achieve the detachable connection of the upper cover 110 and the lower cover 120. For example, the upper cover 110 is provided with the clamping groove 132, and the lower cover 120 is provided with the snap arm 131. Specifically, the side of the upper cover 110 facing the lower cover 120 is provided with a protruding strip, the extension end of the protruding strip is bent upward to form the clamping groove 132. The edge of the lower cover 120 is connected with the snap arm 131, and the snap arm 131 is snap-fitted with the protruding strip. The snap arm 131 has a certain shape recovery ability to be snap-fitted and disengaged with the protruding strip.

[0057] In actual use, the clamping arm 131 has a deformation portion 1313 and a clamping portion 1314 connected to the deformation portion 1313. The end of the deformation portion 1313 away from the clamping portion 1314 is connected to the lower cover 120 and can be integrally formed with the lower cover 120 or fixed by bonding or the like. The deformation portion 1313 is integrally formed with the clamping portion 1314. The clamping portion 1314 is used to clamp and match with the clamping groove 132 on the convex strip. The provision of the deformation portion 1313 facilitates the clamping arm 131 to move out of and into the clamping groove 132, and is convenient to operate.

[0058] As shown in Figure 2 and Figure 4 In some specific embodiments, the clamping arm 131 includes a first arm body 1311 and a second arm body 1312 connected to the first arm body 1311. The first arm body 1311 and the second arm body 1312 are arranged at an angle and are circularly arcuate. The circularly arcuate portion of the first arm body 1311 and the second arm body 1312 serves as the aforementioned deformation portion 1313. The end of the first arm body 1311 away from the second arm body 1312 is connected to the lower cover 120. The end of the second arm body 1312 away from the first arm body 1311 can serve as the aforementioned clamping portion 1314 and is inserted into the clamping groove 132 to clamp and match with the convex strip. The first arm body 1311 and the second arm body 1312 can move close to each other under the action of an external force, at which time the deformation portion 1313 is bent. After the external force is removed, the deformation portion 1313 has a restoring force to promote the first arm body 1311 and the second arm body 1312 to have a movement trend of moving away from each other.
