Description

TECHNICAL FIELD The present invention relates to the technical field of home appliances, and more particularly to cooking utensils.

Prior art cooking appliances (such as electric rice cookers) generally have high heating power to increase cooking speed. However, in actual use, when food is brought to a boil while being heated at a constant high output, a lot of air bubbles are generated, resulting in the problem of spillage.

Related techniques involve introducing cold air into the cooking space to prevent spills. However, the introduced cold air inevitably contains impurities such as oil and smoke from the kitchen environment. Over time, oil and dirt stains can remain in the air pipes, affecting the taste of the food, and can also clog the air pipes and affect the introduction of cold air.

Accordingly, there is a need to provide a cooking utensil that at least partially solves the problems of the prior art.

A series of simplified concepts are introduced in the Summary section, which are explained in more detail in the Embodiments section. The field of the summary of the invention attempts to define the main features and essential technical features of the claimed technical solution, as well as to determine the scope of protection of the claimed technical solution. It's not what I intend.

The present invention provides cooking utensils. The cooking utensil includes a pot body, a cover body, an air intake, and an air transfer device. An inner pot is placed inside the pot body. The cover body is placed on the pot body and can be opened and closed. When the cover body covers and closes the pot body, a cooking space is formed between the cover body and the inner pot. The cover body has an air suction port for drawing in outside air and a steam outlet for discharging steam. The intake port communicates with the cooking space. The air transfer device communicates with the inlet via an inlet line and with the air inlet via an air suction line. The steam outlet is arranged around the air intake.

In the cooking appliance of the present invention, during cooking, when the food in the food storage space in the cooking space is in a boiling state, the air transfer device sucks air through the air suction port and enters the cavity of the cooking space through the intake port. send air into the space. Generally, there is a temperature difference between the transported air and the bubbles within the cavity space. As a result, the transferred air can enter the cavity space and, after coming into contact with the air bubbles accumulated in the cavity space, change the vapor inside the bubbles into liquid, shrink and break the air bubbles, and avoid spilling. . Even when cooking at high speeds with high heating power, spills can be prevented. Furthermore, since the steam outlet is arranged around the air suction opening, the steam discharged through the steam outlet forms a circumferentially closed or continuous steam screen around and above the air suction opening. do. Vapor screens filter the air drawn in through the air intake, preventing impurities such as oil, smoke, and dirt from being drawn into the air intake. This prevents oil and dirt stains from remaining in or clogging the air pipe. In this way, the taste of the food can remain unaffected.

Optionally, the steam outlet is of annular configuration or includes a plurality of secondary steam outlets spaced apart from each other circumferentially of the steam outlet.

Optionally, the distance between the steam outlet and the air inlet is 60 mm or less. When the distance between the steam outlet and the air suction port is in this range, the steam at the steam outlet forms a circumferentially continuous steam screen around the air suction port.

Optionally, the distance between the steam outlet and the air inlet is greater than or equal to 10 mm and less than or equal to 25 mm. When the distance between the steam outlet and the air suction port is in this range, the steam at the steam outlet not only forms a continuous steam screen in the circumferential direction around the air suction port, but also flows through the air suction port. It can also prevent some of the vapor from being inhaled.

Optionally, the air transfer device is an air pump.

Optionally, the air pump has an air pump flow rate of 0.3 LPM or more and 12 LPM or less. This range of air pump flow makes it easy to install the air pump in medium or small electrical appliances, such as cooking utensils, and can achieve relatively good spill prevention results.

Optionally, the air pumping flow rate of the air pump is greater than or equal to 0.5 LPM and less than or equal to 6 LPM. This range of air pump flow makes it easy to install the air pump in medium or small electrical appliances, such as cooking utensils, and can achieve relatively good spill prevention results.

Optionally, the area of the steam outlet is greater than or equal to 100 mm ² and less than or equal to 800 mm ² . In this way, a continuous vapor screen can be formed circumferentially around the air intake.

Optionally, the steam valve assembly is removably attached to the cover lining. The air suction lines include a first air suction line located on the steam valve assembly and a second air suction line located on the cover lining. A second air suction line is connected to the air transfer device. Both ends of the first air suction line communicate with an air suction port and a second air suction line, respectively. A first sealing element is located between the steam valve assembly and the cover lining. In this way, the steam valve assembly can be easily removed for cleaning, and the air enters the second air suction line and finally ends up in the steam valve without passing through the steam filter at the steam outlet. Entry into the cavity space through the gap between the assembly and the cover lining can be prevented.

Optionally, the steam valve assembly includes a steam valve base, a steam valve, a steam valve top cover, and a second sealing element. The steam valve base is removably attached to the cover lining. A first air suction line is located at the steam valve base. A first sealing element is located between the steam valve assembly and the cover lining. The steam valve is located at the steam valve base. A steam valve top cover is removably attached to the steam valve base. A second sealing element is disposed between the steam valve top cover and the steam valve base. The above makes it easy to separate and clean the steam valve upper cover and the steam valve base. At the same time, the second sealing element may prevent steam in the steam line from entering the first air suction line in the steam valve base through the gap between the steam valve top cover and the steam valve base. can.

Optionally, the steam valve assembly includes a steam valve decorative cover on an outer surface of the steam valve assembly. The air suction line has a first end communicating with the air suction port and a second end connected to the air transfer device. A steam valve decorative cover covers the first end of the air suction line.

Optionally, the air inlet is arranged in the steam valve decorative cover. The protrusion at the first end of the air suction line of the steam valve decorative cover is offset from the air suction opening. The steam valve assembly further includes a protrusion projecting downwardly from the steam valve decorative cover. The protrusion is located between the air suction port and the first end of the air suction line. With the above, it is possible to prevent other foreign matter from entering the suction line together with outside air, and it is possible to prevent clogging of the suction line.

Optionally, the horizontal distance between the inner wall of the projection and the outer wall of the first end is 1 mm or more. Thereby, communication between the air suction port and the air suction line can be ensured without water adhering between the inner wall and the outer wall due to its viscosity.

Optionally, the lower end of the protrusion is lower than the first end of the air suction line. This prevents outside air and other foreign matter from entering the air suction line and clogging it due to gravity.

Optionally, the cover body comprises a protruding pedestal located at least partially between the air inlet and the steam outlet. A steam outlet surface is formed between the protruding platform and the steam outlet. The protruding platform is higher than the steam outlet surface. Thereby, the condensed water collects on the steam outlet surface between the steam outlet and the protruding base under the influence of gravity instead of passing through the protruding base and entering the air suction port.

Optionally, the air inlet is arranged on the protruding platform. Thereby, the condensed water collects between the steam outlet and the protruding plateau under the influence of gravity, instead of entering the air intake which is arranged on the protruding plateau.

However, in addition to this detailed description, there may be other ways of implementing the invention. It should not be construed as limited to the embodiments described herein.

The present invention provides a cooking utensil and a cover body thereof. The cooking appliance may be an electric rice cooker, electric pressure cooker, or other electric heating appliance. Additionally, rice cookers can also have functions other than rice cooking, such as making porridge or soup.

FIG. 1 is a schematic diagram showing the principle of a cooking utensil 100 according to an embodiment of the invention. For simplicity, FIG. 1 schematically shows only a partial structure of the cooking utensil 100.

As shown in FIG. 1, the cooking utensil 100 includes a pot body 110. The pot body 110 may be in the general shape of a rectangular parallelepiped with rounded corners, a circular tube, or any other suitable shape. An inner pot 130 in the general shape of a circular tube or other suitable form is disposed within the pot body 110. The inner pot 130 can be freely placed in or removed from the inner pot receiving portion of the pot body 110 to facilitate cleaning of the inner pot 130. Inner pot 130 is used to store food to be cooked, such as rice or soup. The upper part of the inner pot 130 has an upper opening. A user can place ingredients to be cooked into the inner pot 130 through the top opening, or remove cooked food from the inner pot 130 through the top opening.

An inner pot heating device (not shown) for heating the inner pot 130 is disposed within the pot body 110. The inner pot heating device can heat the bottom of the inner pot 130 and/or the sides of the inner pot 130. The inner pot heating device may be an electric heating tube or an induction heating device such as an electromagnetic coil.

As shown in FIG. 1, a cover body 120 is placed on the pot body 110. The shape of the cover body 120 substantially corresponds to the shape of the pot body 110. For example, the cover body 120 may have a rectangular parallelepiped shape with rounded corners. The cover body 120 is disposed on the pot body 110 and can be opened and closed to cover and close the entire upper part of the pot body 110 or at least the inner pot 130 of the pot body 110. Particularly, in this embodiment, the cover body 120 can be disposed on the top of the pot body 110 in a hinged manner that can pivot between a maximum open position and a closed position. The hinge between the cover body 120 and the pot body 110 is generally located at the rear of the cookware 100 to facilitate user manipulation at the front of the cookware 100. It is noted that "front" and "back" referred to herein relate to the position of the user when using the cooking appliance. Specifically, the direction in which the cooking utensil faces the user is defined as "front", and the opposite direction is defined as "back".

As shown in FIG. 1, when the cover body 120 covers and closes the pot body 110, there is a gap between the cover body 120 and the pot body 110 (specifically, a gap between the cover body 120 and the inner pot 130 of the pot body 110). A cooking space 140 (in between) is formed. The cooking space 140 includes a food storage space 141 and a cavity space 142. Specifically, food storage space 141 indicates a space where food is actually placed. Cavity space 142 is located above food storage space 141. In other words, when the cover body 120 covers and closes the pot body 110, the hollow space 142 is a space located between the top surface of the food and the cover body 120. There is no strict boundary between the food storage space 141 and the cavity space 142. Their amounts will vary depending on specific changes in the amount of food.

As shown in FIG. 1, the cover body 120 includes one or more air suction ports 151. One end of the air suction port 151 communicates with the external environment. The other end communicates with an air transfer device 153 (more specifically, an air inlet end of the air transfer device 153) disposed on the pot body 110 or the cover body 120, which will be described in more detail, to allow external air to Cool air (such as cold air) is directed to the cooking space 140 (more specifically, the cavity space 142) via the air transfer device 153.

Specifically, according to one embodiment of the invention, the cover body 120 includes a cover lining 121, as shown in FIGS. 2 and 5. A decorative cover 122A of the cover lining is provided on the upper side (or outside) of the cover lining 121. An inner cover 123 is provided below (or inside) the cover lining 121 . Inner cover 123 may be a removable inner cover so that it can be disassembled for cleaning. The cover body 120 further comprises a steam valve assembly disposed on or removably attached to the cover lining 121. A steam valve decorative cover 122B is provided on the upper side (or top surface) of the steam valve assembly. When the steam valve assembly is removably attached to cover lining 121, cover lining decorative cover 122A and steam valve decorative cover 122B are separate components. When the steam valve assembly is placed on cover lining 121, cover lining decorative cover 122A and steam valve decorative cover 122B are an integral component. The cover lining decorative cover 122A and the steam valve decorative cover 122B together form a decorative cover of the cover body 120. Air inlet 151 is located on the steam valve assembly. More specifically, in one embodiment of the invention, the air suction port 151 is located on the steam valve decorative cover 122B. Note that when the steam valve assembly is placed on the cover lining 121, the air suction port 151 is placed on the decorative cover of the cover body 120 because the cover lining decorative cover 122A and the steam valve decorative cover 122B are integrated decorative covers. It can be assumed that the Of course, the air suction port 151 can also be arranged at other suitable positions on the cover body 120. For example, the air suction port 151 may be disposed on a side surface of the cover body 120.

In addition, "above", "below", "above", "below", "upward", "downward", "above", "below", "high", "low", and "horizontal" Directional and positional terms such as "distance" are used herein to describe various parts within the cover body 120 whose positional relationships are relative to the closed position of the cover body 120. be.

The cooking utensil 100 is also provided with an air inlet 152 that communicates with the cavity 142 . Inlet 152 may be placed at any suitable location on cookware 100. Specifically, according to one embodiment of the invention, the air inlet 152 is located in the cover body 120. More specifically, as shown in FIG. 5, the intake port 152 is arranged on the inner cover 123 of the cover body 120. Of course, the air intake port 152 can also be arranged inside the pot body 110 of the cooking utensil 100. For example, the air inlet 152 can be located in the inner pot 130 of the pot body 110. As shown in FIG. 5, a dispersion cover 170 covering the inlet 152 may also be disposed at the inlet 152. The dispersion cover 170 includes one for redirecting the direction of air entering the cavity 142 or for preventing intruding air from collecting and projecting towards the cavity 142 that creates a depression in the surface of the food to be cooked. Alternatively, a plurality of distributed through holes 171 are provided.

An air transfer device 153 is also arranged in the cooking appliance 100. Air transfer device 153 communicates with air suction port 151 and air intake port 152 . Specifically, air transfer device 153 communicates with air suction port 151 via air suction line 154 . A first end of air suction line 154 communicates with air suction port 151 . A second end of air suction line 154 is connected to air transfer device 153 (specifically, an air inlet end of air transfer device 153). For example, air suction line 154 can be made of a resilient material such as silica. A first end of the air suction line 154 is connected to the air suction port 151 by an insertion, and a second end of the air suction line 154 is connected to the air inlet end of the air transfer device 153 by an insertion. It can be appreciated that when the air transfer device 153 is located within the pot body 110, a portion of the air suction line 154 extends into the pot body 110 and connects with the air transfer device 153 located within the pot body 110. . Air transfer device 153 communicates with inlet 152 via inlet line 155 . One end of the inlet line 155 communicates with the inlet 152 and the other end connects to the air transfer device 153. For example, inlet line 155 can be made of a resilient material such as silica. One end of the inlet line 155 is connected to the inlet 152 by insertion. The other end is connected to the air outlet end of the air transfer device 153. Therefore, the air suction port 151 , the air suction line 154 , the air transfer device 153 , the suction port line 155 , and the suction port 152 are used to suck air (external cold air, etc.) from outside the cooking appliance 100 into the cavity space 142 . together form an air transfer system.

During cooking, when the food in the food storage space 141 is in the boiling stage, viscous substances such as starch in the food being cooked separate into water and enclose steam, generating a lot of bubbles. A large amount of these bubbles will accumulate in the cavity space 142 above the food storage space 141. The air transfer device 153 can suck air through the air suction port 151 and transfer the sucked air to the cavity space 142 through the suction port 152 . Generally, there is a temperature difference between the transferred air and the bubbles within the cavity 142. As a result, after the transferred air enters the cavity space 142 and comes into contact with the air bubbles accumulated within the cavity space 142, it can change the vapor within the air bubbles into liquid, causing the air bubbles to contract and burst, thereby , spills can be avoided. This prevents spillage even when cooking with high heating power.

As shown in FIGS. 1 and 2, the cover body 120 is further provided with a steam outlet 182 for discharging steam. Specifically, steam outlet 182 is located on the steam valve assembly. More specifically, the steam outlet 182 is located on the steam valve decorative cover 122B. Note that when the steam valve assembly is placed on the cover lining 121, the steam outlet 182 is placed on the decorative cover of the cover body 120 because the steam valve decorative cover 122B and the cover lining decorative cover 122A are integrated decorative covers. Placed. Steam outlet 182 communicates with steam inlet 181 via steam line 180. Steam inlet 181 communicates with cavity space 142. Steam inlet 181 may be located on inner cover 123. Of course, the steam outlet 182 and the steam inlet 181 can also be arranged at other suitable locations on the cover body 120. For example, the steam outlet 182 can be located on the side of the cover body 120. In a cover body 120 without an inner cover 123, the steam inlet 181 can also be arranged directly on the cover lining 121.

As mentioned above, after the air transferred by the air transfer device 153 enters the cavity 142, it converts the vapor in the bubbles accumulated in the cavity 142 into liquid and contracts, thereby destroying the bubbles. be able to. After hitting the bubbles, the transferred air can be exhausted to the outside through the steam inlet 181, the steam line 180, and the steam outlet 182 with or in the form of steam to remove some of the heat. , In this way, the generation of air bubbles can be suppressed and the pressure can be lowered, further preventing spillage.

Based on the idea of the present invention, the steam outlet 182 is arranged to surround the air suction port 151, as shown in FIGS. 1 and 3. That is, the steam outlet 182 is arranged around the air suction port 151. During operation of the cooking appliance 100, a large amount of steam is generated within the cavity space 142 when the food within the food storage space 141 is in the boiling stage. This steam is exhausted via steam inlet 181, steam line 180 and steam outlet 182. At the same time, as described above, the air transfer device 153 also starts operating to suck air through the air suction port 151 and transfer the sucked air to the cavity space 142 through the suction port 152. The steam outlet 182 is arranged to surround the air suction port 151, so that the steam discharged through the steam outlet 182 is circumferentially closed or continuous around and above the air suction port 151. It forms a vapor screen that acts as a filter for the air sucked into the air suction port 151, thereby preventing foreign matter such as oil, smoke, dirt, etc. from being sucked into the air suction port 151. can. As a result, it prevents oil and dirt stains from remaining in the air line or clogging the air line and affecting the taste of the food.

Specifically, in one embodiment of the invention, the steam outlet 182 is arranged around the air inlet 151, as shown in FIG. Steam outlet 182 includes a plurality (such as two, three, or more) of secondary steam outlets spaced apart from each other along its circumference. The plurality of secondary steam outlets can be equally spaced or unevenly spaced. The secondary steam outlet can be of any suitable shape, such as arcuate, circular, rectangular, etc. The shapes of the plurality of secondary steam outlets may be the same or different.

In another embodiment of the invention, the steam outlet 282 is configured to be in an annular configuration circumferentially closed around the air inlet 151, as shown in FIG. It should be noted that "annular form" as used herein means any suitable form that is circumferentially closed (in other words, its head is connected to its end) and is empty inside; The outline can be of any suitable shape, such as a circle, rectangle, pentagon, hexagon, etc.

The applicant has discovered that the distance L between the steam outlet 182 and the air suction port 151 affects the filtration effectiveness of the air drawn through the air suction port 151. If the distance L between the steam outlet 182 and the air suction port 151 is too small, the steam outlet 182 is too close to the air suction port 151, and a part of the steam discharged through the steam outlet 182 will be transferred to the air suction port 151. This will affect the effectiveness of cooling and spill prevention. If the distance L between the steam outlet 182 and the air suction port 151 is too large, the steam screen formed by the steam released through the steam outlet 182 around the air suction port 151 will be discontinuous in the circumferential direction. or have a relatively low density, which will weaken the filtration effect of the air sucked through the air suction port 151.

In a preferred embodiment of the invention, the distance L between the steam outlet 182 and the air suction port 151 is 60 mm or less. More preferably, the distance L between the steam outlet 182 and the air suction port 151 is 10 mm or more and 25 mm or less. The present applicant believes that when the distance L between the steam outlet 182 and the air suction port 151 is within this range, the steam at the steam outlet 182 passes through a continuous steam screen in the circumferential direction around the air suction port 151. It has also been discovered that the air inlet 151 can be prevented from inhaling some of the vapor.

Additionally, Applicants have discovered that the area of the steam outlet 182 and the flow rate of the air transfer device 153 influence the formation of a steam screen around the air suction port 151. If the area of the steam outlet 182 is relatively large, the air transfer device 153 is large enough to ensure that the steam at the steam outlet 182 can form a circumferentially continuous steam screen around the air suction port 151. Flow rate is required.

Optionally, in one embodiment of the invention, air transfer device 153 is an air pump. Preferably, the air pump flow rate (no load) of the air pump is 0.3 LPM or more and 12 LPM or less. More preferably, the air pump flow rate (no load) of the air pump is 0.5 LPM or more and 6 LPM or less, which facilitates installation in a medium-sized or small electric home appliance such as the cooking appliance 100, and A relatively good effect of spill prevention can be achieved. Correspondingly, the area of the steam outlet 182 is greater than or equal to 100 mm ² and less than or equal to 800 mm ² . Preferably, the area of the steam outlet 182 is 150 mm ² or more and 650 mm ² or less. Note that "area" here means the actual total area from which air is discharged. Applicant has discovered that having the air pump flow rate and the area of the steam outlet 182 within the ranges described above facilitates the formation of a circumferentially continuous steam screen around the air suction port 151.

Air transport device 153 may be placed at any suitable location on the cooking appliance. In one embodiment of the present invention, as shown in FIG. 5, an air transfer device 153 is disposed on the cover body 120 and communicates with an air suction port 151 disposed on the cover body 120 via an air suction line 154; It also communicates with an air intake port 152 disposed on the cover body 120 via an air inlet line 155 . In particular, in one embodiment of the invention, the receiving space for receiving the air transport device 153 and/or other components is located between the cover lining 121 and the decorative cover (in particular the decorative cover 122A of the cover lining). formed between. In particular, the cover lining 121 forms a downwardly concave depression forming a receiving space. Air transfer device 153 is arranged in the receiving space. With the above, the structure of the cover main body 120 can be made more compact.

The air transfer device 153 is arranged in the receiving space and separated from the cover lining 121 and the decorative cover via a bracket, which prevents the generation of noise due to direct contact of the air transfer device 153 with the cover lining 121 and the decorative cover. is avoided. More specifically, the bracket can include a support part and a fixation part. The fixing part is connected to the cover lining 121. The fixing part can be fixed to the cover lining 121 by any suitable means, such as screw threads or adhesive fasteners. The support part is connected to the fixed part. The support portion and the fixation portion may be an integral component or separate components. The support is separated from the cover lining 121 and the decorative cover, so that when the air transfer device 153 is supported by the support, the air transfer device 153 is separated from the cover lining 121 and the decorative cover. That is, the air transfer device 153 is not in direct contact with the cover lining 121 or the decorative cover, thereby avoiding the generation of noise when the air transfer device 153 is in direct contact with the cover lining 121 and the decorative cover during operation. . In the illustrated embodiment, the bracket is configured in the shape of an Ω. Note that the form of the bracket is not limited to the illustrated embodiment. For example, in other implementations of the invention, the support of the bracket can have an annular shape. In this way, the air transfer device 153 can be supported on the support part by passing through the support, which can facilitate the installation of the air transfer device 153.

In an unillustrated embodiment of the invention, the air transfer device 153 can also be located within the pot body. In fact, if the air transfer device 153 is located within the cover body, the temperature of the environment surrounding the air transfer device may be too high due to the accumulation of steam under the cover body, thereby causing the air transfer device life span is reduced and usage costs are increased. Note that if the air transfer device 153 is disposed within the pan body 110, the air suction line 155 may extend into the pan body 110 from the pivot joint between the cover body 120 and the pan body 110. . Conversely, air inlet line 154 can extend into cover body 120 from the pivot joint between pan body 110 and cover body 120.

As mentioned above, the steam valve assembly is located within the cover body 120. Specifically, in one embodiment of the invention, the steam valve assembly is removably attached to cover lining 121. As shown in FIGS. 5 and 6, a first end of the air suction line 154, the end communicating with the air suction port 151, is disposed within the steam valve assembly, thereby connecting the air suction line 154 to the steam valve assembly. Communication can be facilitated with an air suction port 151 located on the steam valve assembly.

Specifically, air suction line 154 includes a first air suction line 154A and a second air suction line 154B. First air suction line 154A and second air suction line 154B are separate components. A first air suction line 154A is located at the steam valve assembly. The second air suction line 154B is arranged in the cover lining 121. Both ends of the first air suction line 154A communicate with the air suction port 151 and the second air suction line 151B, respectively. Specifically, the first end of the first air suction line 154A communicates with the air suction port 151. A second end of the first air suction line 154A communicates with a second air suction line 154B. For example, the second end of the first air suction line 154A can be connected to the second air suction line 154B by insertion. The air sucked in through the air suction port 151 reaches the air transfer device 153 through the first air suction line 154A and the second air suction line 154B, and enters the cavity space through the air inlet line 155. . The first air suction line 154A located on the steam valve assembly and the second air suction line 154B located on the cover lining 121 are separate components so that the steam valve assembly cannot be removed from the cover lining 121. can.

The first sealing element 192 is disposed between the steam valve assembly and the cover lining 121 so that air bypasses steam filtration at the steam outlet 182 and prevents air from being filtered by the steam at the steam outlet 182. It is possible to prevent the air from entering the second air suction line 154B through the gap and ultimately from entering the cavity space.

Specifically, the steam valve assembly includes a steam valve base 191. Steam valve 193 is located at steam valve base 191 . Steam valve base 191 is removably attached to cover lining 121. The first air suction line 154A is located at the steam valve base 191. A first sealing element 192 is arranged between the steam valve base 191 and the cover lining 121. The first sealing element 192 may be a radial sealing element, thereby facilitating installation and achieving a good sealing effect.

More specifically, the cover lining 121 includes a cover lining projection 121A that projects upward (ie, toward the steam valve base 191). The steam valve base 191 includes a recess 191A that is concave upward (that is, in the direction away from the cover lining 121). The recess 191A can cooperate with the cover lining projection 121A. While installed, cover lining protrusion 121A is received in recess 191A of steam valve base 191. The first sealing element 192 surrounds the cover lining projection 121A, so that the first sealing element 192 is located between the cover lining projection 121A and the side wall of the recess 191A, and the first sealing element 192 surrounds the cover lining projection 121A and the side wall of the recess 191A. Ensure a tight seal between the As described above, air cannot enter the second air suction line 154B through the gap between the steam valve base 191 and the cover lining 121, and by bypassing steam filtration at the steam outlet, Finally, it is impossible to enter the hollow space. First sealing element 192 may be made of any suitable resilient material, such as silica. Of course, the first sealing element 192 can also be an axial sealing element arranged between the cover lining projection 121A and the bottom wall of the recess 191A.

Furthermore, the steam valve assembly further includes a steam valve top cover 194. A steam valve top cover 194 is removably mounted over the steam valve base 191. At least a portion of steam passage 180 is formed between steam valve upper cover 194 and steam valve base 191 . The steam valve decorative cover 122B is placed on the steam valve top cover 194 to improve the aesthetic aspect of the cookware 100 exterior. A through hole communicating with the steam outlet 182 of the steam valve decorative cover 122B is arranged on the steam valve upper cover 194. A second sealing element 195 is located between the steam valve top cover 194 and the steam valve base 191. The second sealing element 195 may also be a radial sealing element, thereby facilitating installation and achieving good sealing results.

Specifically, the steam valve upper cover 194 is provided with a mounting hole 194A. The steam valve base 191 is provided with a mounting portion 191B. The attachment portion 191B of the steam valve base 191 can pass through the attachment hole 194A of the steam valve upper cover 194. The second sealing element 195 covers the attachment portion 191B of the steam valve base 191 such that the second sealing element 195 is disposed between the steam valve top cover 194 and the attachment portion 191B of the steam valve base 191. will be done. The second sealing element 195 can prevent steam from entering the first air suction line 154A of the steam valve base 191 through the gap between the steam valve top cover 194 and the steam valve base 191. .

Note that in this embodiment, the air suction lines 154 are shown to include a first air suction line 154A located at the steam valve assembly and a second air suction line 154B located at the cover lining 121. However, the air suction line 154 may also include only a first air suction line 154A located at the steam valve assembly. In this case, the first end of the first air suction line 154A communicates with the air suction port 151, and the second end thereof is connected to the air transfer device.

In addition, in this embodiment, the first air suction line 154A disposed on the steam valve base 191 and the second air suction line 154B disposed on the cover lining 121 are separated, whereby the cover lining of the steam valve base 191 is separated. Although shown as facilitating attachment to 121 in a removable manner, in another embodiment of the invention (not shown), first air suction line 154A and second air suction line 154B can also be an integral component. Air suction line 154 is inserted into a steam valve assembly that is removable from cover lining 121. In this case, the first air suction line 154A and the second air suction line 154B form an integral component, so that the first sealing element 192 can be omitted from between the steam valve assembly and the cover lining 121.

As shown in FIGS. 5 and 6, cover body 120 further includes a joint component 124. As shown in FIGS. Junction component 124 has a first end of air suction line 154 , an end that communicates with air suction port 151 and forms an air inlet gap between it and the first end of air suction line 154 . cover the area. On the other hand, the joint component 124 covers the first end of the air suction line 154 and prevents the first end of the air suction line 154 from being exposed to the outside and other foreign objects (water, cockroaches, etc.). etc.) from entering the air suction line 154, thereby preventing clogging of the air suction line 154 and ensuring that the movement of outside air into the cooking cavity is unaffected. On the other hand, an air inlet gap is formed between the joint component 124 and the first end of the air suction line 154 such that the air suction line 154 communicates with the air suction port 151 and the outside air is drawn into the air suction port. Air suction line 154 can be entered through 151 .

Junction component 124 includes a decorative cover disposed on the outer surface of cover body 120 and covering the first end of air suction line 154 . Specifically, in one embodiment of the invention, interface component 124 includes a steam valve decorative cover 122B located on an exterior surface of the steam valve assembly. The steam valve decorative cover 122B covers the first end of the air suction line 154, that is, the end communicating with the air suction port 151. More specifically, the steam valve decorative cover 122B covers the first end of the first air suction line 154A, that is, the end that communicates with the air suction port 151. That is, when the cover body 120 is in the closed position, the first end of the air suction line 154 is covered by the steam valve decorative cover 122B, such that the first end is connected to the cover body 120 or the cooking utensil. 100 so that it cannot be seen from above. It can be seen that the first end protrusion of the air suction line 154 on the decorative cover is offset from the air suction opening 151. Specifically, in one embodiment of the invention, the protrusion at the first end of the air suction line 154 is offset from the air suction port 151 disposed on the steam valve decorative cover 122B. Since the steam valve decorative cover 122B covers the first end of the air suction line 154, the first end of the air suction line 154 is not exposed to the outside, thereby preventing other foreign objects (such as water or cockroaches) from entering the air suction line 154. This prevents air from entering the air suction port 154.

Additionally, joint component 124 further includes a protrusion 124A that projects downwardly from the decorative cover (specifically, steam valve decorative cover 122B). The protrusion 124A is located between the air suction port 151 and the first end of the air suction line 154. Protrusion 124A surrounds the first end of air suction line 154. In this way, the portion of the steam valve decorative cover 122B located at the first end of the air suction line 154 and the protrusion 124A together form an inverted cover over the first end of the air suction line 154. . Thanks to the presence of the protrusion 124A, the air coming from the air suction port 151 cannot directly enter the air suction line 154, but is blocked by the protrusion 124A and enters the air suction line 154 in a zigzag pattern. In this way, other foreign objects can be prevented from entering the air suction line 154 along with the outside air due to gravity, thereby preventing the air suction line 154 from becoming clogged.

It can be seen that the inner wall of the protrusion 124A needs to be separated from the outer wall of the first end of the air suction line 154, so that the air suction port 151 can communicate with the air suction line 154. The applicant has discovered that if the distance between the inner wall of the protrusion 124A and the outer wall of the first end of the air suction line 154 is too small, the communication between the air suction port 151 and the air suction line 154 may be reduced due to the viscosity of water. found that it is more susceptible to Therefore, optionally, the horizontal distance between the inner wall of the protrusion 124A and the outer wall of the first end of the air suction line 154 is greater than or equal to 1 mm, so that water does not adhere therebetween due to its viscosity. First, communication between the air suction port 151 and the air suction line 154 is ensured.

Optionally, the lower end of protrusion 124A is lower than the first end of air suction line 154. In this way, it can be ensured that other foreign objects do not enter the air suction line 154 along with the outside air due to gravity and clog the air suction line 154.

Since the steam outlet 182 is arranged around the air suction port 151, the steam coming from the steam outlet 182 may form a small amount of condensed water around the air suction port 151. Optionally, cover body 120 may further include a waterproof component, thereby preventing liquid from entering air intake port 151.

Specifically, in one embodiment of the invention, the waterproof component is a protruding pedestal located between the air inlet 151 and the vapor outlet 182. The protruding platform is spaced apart from the steam outlet 182. A steam outlet surface is formed between the protruding platform and the steam outlet 182. The steam outlet surface can be higher than the steam outlet 182, or it can be flush with the steam outlet, or it can be lower than the steam outlet. The protruding platform is higher than the steam outlet surface. Further optionally, the protruding pedestal is higher than the steam outlet 182. As described above, the protruding base forms a block between the steam outlet 182 and the air suction port 151, and since the protruding base is higher than the steam outlet surface, the condensed water is Instead of passing over the platform and entering the air inlet 151, it collects between the vapor outlet surfaces due to gravity.

Optionally, in another embodiment of the invention, the waterproofing component is a protruding pedestal 125 located partially between the air inlet 151 and the steam outlet 182. The protruding platform 125 is spaced apart from the steam outlet 182 and a steam outlet surface is formed between the protruding platform 125 and the steam outlet 182. The protruding platform 125 is higher than the steam outlet surface. The air suction port 151 is arranged on the protruding base portion 125. Since the protruding platform 125 is higher than the steam outlet surface, the condensed water collects on the steam outlet surface by gravity instead of passing through the protruding platform 125 and entering the air suction port 151.

In summary, in the cover body of the present invention, when used in a cooking utensil, the steam outlet is arranged around the air suction port, so that the steam discharged from the steam outlet is circulated around and above the air suction port. Forming a circumferentially closed or continuous steam screen. It can filter the air drawn into the air intake, prevent impurities such as oil and smoke from being drawn into the air intake, and prevent oil and dirt stains from remaining in the air line or clogging it. It also prevents the taste of food from being affected.
