Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliances, and in particular to a cooking device. Background Art

[0002] With the overall improvement of social living standards, cooking equipment such as steamers and steam ovens are becoming more and more popular among consumers because they can enrich cooking methods and reduce cooking difficulty.

[0003] Cooking devices with steam cooking functions require a continuous flow of hot steam into the cooking chamber to maintain the desired cooking temperature. To prevent excessive pressure within the cooking chamber, conventional steam cooking devices include a condenser tube installed outside the inner pot. The condenser tube's air inlet is connected to the inner pot's steam outlet. During cooking, the hot steam in the cooking chamber is discharged through the steam outlet into the condenser tube, where it is condensed and cooled.

[0004] However, since hot steam comes into contact with food during the cooking process, the hot steam overflowing the steam discharge port carries grease. Especially when cooking food with a high grease content, the amount of grease carried in the hot steam is also high. When the hot steam condenses in the condenser, the grease adheres to the inner wall of the condenser, which can easily lead to a decrease in the flow rate in the condenser or even blockage, affecting the steam discharge efficiency; after long-term use, it is also easy for bacteria and other pollutants to breed inside the condenser, causing odor, affecting the user experience of the cooking equipment.

[0046] Example 1

[0047] Embodiments of the present invention provide a cooking device with a steam cooking function that can condense and cool steam during or after cooking, and can also clean the steam condensation channel, thereby improving the user experience of the cooking device. The cooking device may be, but is not limited to, an electric steamer, a steam oven, or a microwave oven / steamer-bake combination.

[0048] like Figures 1 to 5As shown, the cooking device provided in this embodiment includes a housing, a steam cooking module 4, and a controller. The housing includes an inner pot assembly 5, a base mounted on the bottom of the inner pot assembly 5, and a housing surrounding the outer portion of the inner pot assembly 5. The inner pot assembly 5 has a cooking cavity with an open front. The steam cooking module 4 includes a steam generator 41 and a water inlet circuit for supplying water to a water inlet 1121 of the steam generator 41. The steam generator 41 generates hot steam and introduces the hot steam into the cooking cavity to cook food therein. The controller is mounted on the housing and is in communication with the steam cooking module 4 to control the operation of the steam cooking module 4.

[0049] The cooking apparatus further includes a steam condensing device and a cleaning pipe 6 disposed outside the inner pot assembly 5. The steam condensing device includes a condensing assembly 2 having a condensing channel 211, the air inlet of which is connected to the steam exhaust port 521. The water inlet of the cleaning pipe 6 is connected to the steam supply line of the steam generating device 41, and the water outlet of the cleaning pipe 6 is selectively connected to the inlet of the condensing channel 211.

[0050] The cooking device provided in this embodiment is provided with a cleaning pipe 6, and the outlet end of the cleaning pipe 6 is selectively connected to the inlet end of the condensation channel 211, so that after the cooking device has been used for a period of time, cleaning water or hot steam can be introduced into the condensation channel 211 through the cleaning pipe 6 to flush and clean the condensation channel 211, thereby reducing the probability of grease accumulation in the condensation channel 211, thereby reducing the probability of flow reduction or blockage of the condensation channel 211, and ensuring the condensation effect of the condensation component 2 for long-term use; at the same time, since the inlet end of the cleaning pipe 6 is connected to the steam supply pipeline or water inlet waterway of the steam generating device 41, the water supply structure of the cleaning pipe 6 adopts the structure of the existing cooking equipment, thereby reducing the improvement cost of the cooking equipment.

[0051] In this embodiment, the steam condensation device further includes a connecting joint 1 having an inner cavity, an outlet 1131, and a water inlet 1121. The water inlet 1121 is connected to the water outlet of the cleaning pipe 6, and the outlet 1131 is connected to the inlet of the condensation channel 211. A switch 12 is disposed within the inner cavity and is movable between a first position and a second position, with the outlet 1131 positioned between the first and second positions. When the switch 12 is in the first position, the water inlet 1121 is connected to the outlet 1131 through the inner cavity. When the switch 12 is in the second position, the water inlet 1121 and the outlet 1131 are separated by the switch 12.

[0052] That is, in this embodiment, the selective conduction between the water inlet 1121 and the outlet 1131 is achieved through the movement of the switch member 12 in the inner cavity, thereby achieving selective conduction between the cleaning pipe 6 and the condensation channel 211. At the same time, the switch member 12 also serves to connect the condensation channel 211 and the cleaning pipe 6, thereby simplifying the structure, reducing costs, and improving structural compactness.

[0053] In other embodiments, a control valve may also be provided on the cleaning pipe 6 , and the control valve controls the on-off of the cleaning pipe 6 , thereby controlling the selective conduction between the cleaning pipe 6 and the inlet end of the condensation channel 211 .

[0054] In this embodiment, the switch member 12 is slidably and sealedly fitted with the cavity wall of the inner cavity. The switch member 12 slides between a first position and a second position to isolate the inner cavity into a first chamber 1111 and a second chamber 1112 that are not connected to each other. The first chamber 1111 is connected to the water inlet 1121. When the switch member 12 is in the first position, the first chamber 1111 is connected to the discharge outlet 1131; when the switch member 12 is in the second position, the first chamber 1111 and the discharge outlet 1131 are blocked, and the second chamber 1112 is connected to the discharge outlet 1131.

[0055] An elastic return member 15 is disposed within the inner cavity. The elastic return member 15 applies a force toward the first chamber 1111 to the switch member 12, causing the switch member 12 to maintain or return to the second position. The switch member 12 can be pushed to the first position when the pressure exerted on it by the fluid in the first chamber 1111 is greater than the elastic force of the elastic return member 15. This arrangement can automatically connect the water inlet 1121 and the outlet 1131 when water is supplied to the cleaning pipe 6. When water is not supplied to the cleaning pipe 6, the switch member 12 can automatically return to the first position under the restoring force of the elastic return member 15. This eliminates the need for an additional drive structure for the switch member 12, resulting in a simple structure and low cost. Furthermore, when the condensation channel 211 does not need to be cleaned, the water inlet 1121 and the outlet 1131 remain disconnected, preventing steam in the condensation channel 211 from flowing into the cleaning pipe 6 through the outlet 1131, thereby ensuring smooth steam discharge and condensation.

[0056] In other embodiments, a driving structure may also be used to drive the switch element 12 to switch between the first position and the second position.

[0057] Furthermore, the inner cavity has a steam inlet 1113, which is always connected to the second chamber 1112, and the steam inlet 1113 is connected to the steam exhaust port 521 of the inner pot assembly 5, so that the hot steam in the cooking cavity can enter the condensation channel 211 through the steam exhaust port 521, the second chamber 1112 and the exhaust port 1131, so that the connecting joint 1 not only serves to connect the cleaning pipe 6 and the condensation assembly 2, but also serves to connect the inner pot assembly 5 and the condensation assembly 2, thereby improving the compactness of the structure and reducing the structural complexity.

[0058] Furthermore, the housing 11 includes a cylindrical body 111, the extension direction of which corresponds to the sliding direction of the switch member 12. The cylindrical body 111 is preferably open at one end and closed at the other. The open end of the cylindrical body 111 forms a steam inlet 1113, through which both the switch member 12 and the elastic return member 15 can enter and exit the inner cavity, thereby improving the ease of assembly and disassembly of the connector 1. A mounting edge 114 extends radially outward from the open end of the cylindrical body 111. The mounting edge 114 is in contact with and removably connects to the outer cover 52 of the inner liner assembly 5.

[0059] In this embodiment, the cross section of the inner cavity is circular, and the switch member 12 has a circular structure adapted to the cross section of the inner cavity to improve the sliding smoothness of the switch member 12. In other embodiments, the cross section of the inner cavity can also be rectangular or other shapes, as long as the cross section of the inner cavity matches the shape of the switch member 12.

[0060] A discharge pipe portion 113 protrudes from the side wall of the cylinder 111. The end of the discharge pipe portion 113 forms a discharge port 1131. The discharge pipe portion 113 is connected to the condensation channel 211 in a sealed plug-in manner to improve the connection convenience between the shell 11 and the condensation assembly 2. An inlet pipe portion 112 is protruded from the side wall of the cylinder 111. The end of the inlet pipe portion 112 forms a water inlet 1121. The inlet pipe portion 112 is connected to the water outlet end of the cleaning pipe 6 in a sealed plug-in manner to improve the connection convenience between the shell 11 and the cleaning pipe 6, thereby improving the efficiency of assembly and disassembly of the steam condensing device.

[0061] The inner liner assembly 5 includes an inner liner 51 and an outer cover 52 installed on the outside of the inner liner 51. A steam outlet is provided on one side of the inner liner 51, and a steam exhaust port 521 is provided on the outer cover 52. The steam exhaust port 521 is connected to the steam outlet. The connecting joint 1 is installed on the side of the outer cover 52 away from the inner liner 51, and the steam inlet port 1113 is directly connected to the steam exhaust port 521.

[0062] In this embodiment, a guide hole is provided on the inner tank assembly 5, and the switch member 12 is connected to a guide rod 13. The extension direction of the guide rod 13 is the same as the sliding direction of the switch member 12. The guide rod 13 is slidably inserted into the guide hole to provide guidance for the sliding of the switch member 12, thereby improving the sliding smoothness of the guide switch member 12 and avoiding the switch member 12 from getting stuck due to sliding deviation during the sliding process.

[0063] A limiting component 14 is provided at one end of the guide rod 13 away from the switch component 12. The limiting component 14 is located outside the guide hole on the side away from the switch component 12 and is restricted from passing through the guide hole. The limiting component 14 is abutted against the inner tank assembly 5 to limit the sliding stroke of the switch component 12 along the direction of extruding the first chamber 1111, thereby preventing the switch component 12 from sliding over the water inlet 1121 and causing the steam inlet 1113 to be connected to the cleaning pipe 6; at the same time, the setting of the limiting component 14 has a simple structure and is easy to set up, which can simplify the structure of the shell 11 and reduce the processing difficulty of the shell 11.

[0064] The switch member 12 is preferably detachably connected to the guide rod 13 and is preferably made of an elastic material such as rubber or silicone to ensure a tight seal between the first chamber 1111 and the second chamber 1112. The guide rod 13 is preferably made of metal or hard plastic to ensure reliable sliding. The stopper 14 can be integrally formed with the guide rod 13 or mounted to the guide rod 13 by welding or screwing.

[0065] In this embodiment, at least two condensation channels 211 are provided, and the exhaust ports 1131 are arranged in a one-to-one correspondence with the condensation channels 211. This allows hot steam to flow into multiple condensation channels 211 for condensation, reducing the length requirement of the condensation channels 211 while ensuring effective condensation of the hot steam. The exhaust pipe portion 113 is arranged in a one-to-one correspondence with the exhaust ports 1131. Furthermore, the multiple exhaust ports 1131 are spaced circumferentially along the inner cavity, and all exhaust ports 1131 are positioned identically in the sliding direction of the switch member 12, ensuring that all exhaust ports 1131 are simultaneously connected to the first chamber 1111 or the second chamber 1112.

[0066] In this embodiment, the steam generating device 41 is a steam generator disposed outside the inner pot assembly 5. In other embodiments, the steam generating device 41 may also be an evaporation tray disposed at the bottom of the cooking cavity. The specific structure of the steam generating device 41 and its mounting structure on the inner pot assembly 5 can be configured with reference to existing technologies and are not the focus of this embodiment and will not be further described.

[0067] In this embodiment, the water inlet 1121 of the cleaning pipe 6 is connected to the water inlet circuit, which supplies cleaning water to the condensation channel 211, thereby reducing cleaning costs. Specifically, the water inlet circuit includes a water tank 43, a water inlet pipe 42, and a water pump 44. The inlet end of the water inlet pipe 42 is connected to the water tank 43, and the outlet end of the water inlet pipe 42 is connected to the steam generator 41. The water pump 44 is provided on the water inlet pipe 42 to pump water from the water tank 43 to the steam generator 41.

[0068] In this embodiment, the water inlet end of the cleaning pipe 6 is connected to the water inlet pipe 42, thereby simplifying the connection structure between the pipe and the water tank 43, simplifying the structure of the water tank 43, and improving the convenience of taking the water tank 43 out, thereby facilitating the addition of water to the water tank 43 or the cleaning of the water tank 43. In other embodiments, the water inlet end of the cleaning pipe 6 can also be directly connected to the water tank 43.

[0069] The water tank 43 is disposed on the front side of the base, retractable in the front-to-back direction, facilitating access. In other embodiments, the water tank 43 may also be disposed on the top of the inner liner assembly 5 or on either side of the inner liner assembly 5. Any prior art arrangement of the water tank 43 may be applied to the present invention, and the present invention does not limit the location or specific structure of the water tank 43.

[0070] In this embodiment, the water inlet end of the cleaning pipe 6 is connected to the water inlet pipe 42 and is located upstream of the water pump 44. The water inlet pipe 42 is provided with a water inlet on-off valve 45 downstream of the water pump 44. The water flow driven by the water pump 44 can be controlled to flow to the cleaning pipe 6 or to the steam generating device 41 by controlling the on-off control of the water inlet on-off valve 45.

[0071] In other embodiments, the cooking equipment also includes a three-way valve, the water inlet pipe 42 is connected in series to the first port and the second port of the three-way valve, the water inlet end of the cleaning pipe 6 is connected to the third port of the three-way valve, and the valve core in the three-way valve controls the connection between the first port and the second port or the third port, thereby controlling the direction of water flow in the water inlet pipe 42.

[0072] In this embodiment, an electric heating element is provided on the cleaning pipe 6 , so that the water in the cleaning pipe 6 can be heated by the electric heating element, thereby increasing the temperature of the water entering the cleaning pipe 6 , thereby improving the cleaning effect of the condensation channel 211 .

[0073] Furthermore, a one-way valve is provided on the cleaning pipe 6, which only allows fluid to flow from the cleaning pipe 6 to the water inlet 1121 to avoid failure of the switch 12 causing steam to leak through the cleaning pipe 6, thereby improving the safety and reliability of steam discharge and improving the user experience of the cooking equipment.

[0074] To collect the water discharged from condensation channel 211, in this embodiment, the steam condensation device further includes a recovery assembly 3. Recovery assembly 3 includes a water collection box 31. Water collection box 31 is installed below condensation channel 211 and has a water collection chamber. The outlet end of condensation channel 211 is connected to the water collection chamber. As a result, condensed water or cleaning water in condensation channel 211 is discharged into the water collection chamber, thereby collecting the discharged water.

[0075] Furthermore, the connecting joint 1, the condensation assembly 2 and the water collecting box 31 are arranged in sequence from top to bottom, and the condensation channel 211 extends downward from the air inlet end to the air outlet end, so that the condensed water in the condensation channel 211 can be automatically discharged into the water collecting chamber under the action of gravity.

[0076] In this embodiment, a drain port is provided at the bottom of the water collection box 31, to which a drain pipe 32 is connected. The outlet of the drain pipe 32 is connected to the water inlet pipe 42 and is located upstream of the water inlet of the cleaning pipe 6. A drain control valve 33 is provided on the drain pipe 32. As a result, water in the water collection box 31 flows back through the drain pipe 32 to the water tank 43 and the water inlet pipe 42, thereby allowing the condensed water or cleaning water to be cleaned by removing and placing the water tank 43. Furthermore, this arrangement allows water to circulate in the circulating water path formed by the water tank 43, the cleaning pipe 6, the inner cavity, the condensation channel 211, the water collection box 31, and the drain pipe 32 when the connector 1 is in the cleaning state, thereby improving the cleaning effect of the condensation channel 211 and saving water resources.

[0077] In this embodiment, the condensation assembly 2 includes a radiator 22, a condenser pipe 21, and a heat dissipation fan 23. The inner cavity of the condenser pipe 21 forms a condensation channel 211, and the upper end of the condenser pipe 21 is connected to the discharge port. The condenser pipe 21 includes a plurality of condensation sections connected in sequence from top to bottom through a bend section; the radiator 22 includes a plurality of heat dissipation fins arranged side by side and spaced apart in a horizontal direction, and each condensation section passes through a plurality of heat dissipation fins. The heat dissipation fan 23 guides the external cooling airflow to blow toward the radiator 22, so that the radiator 22 dissipates heat to the discharge pipe. At the same time, the cooling airflow takes away the heat from the radiator 22, ensuring the heat dissipation effect of the radiator 22 on the discharge pipe, so that the hot steam can be condensed and cooled when flowing in the discharge pipe, reducing the steam content and steam temperature discharged from the discharge pipe, and improving the user experience of the steam discharge device and cooking equipment. Specifically, the discharge main pipe includes a condensation section and a bend section.

[0078] In other embodiments, the condensation assembly 2 may also adopt other forms, as long as it is provided with a condensation channel 211 capable of condensing steam.

[0079] Example 2

[0080] This embodiment provides a cooking device, and the basic structure of the cooking device provided in this embodiment is the same as that of the first embodiment, with only some settings being different.

[0081] In this embodiment, the cleaning pipe 6 includes a cleaning water pipe and a steam pipe. The cleaning pipe 6 includes a cleaning water pipe, the water inlet end of the cleaning water pipe is connected to the water inlet pipe 42 or the water tank 43, and the water outlet end of the cleaning water pipe is connected to the inlet end of the condensation channel 211; and / or, the cleaning pipe 6 includes a steam pipe, the inlet end of the steam pipe is connected to the steam supply pipeline, the outlet end of the steam pipe is connected to the inlet end of the condensation channel 211, and the steam pipe is selectively conductive.

[0082] That is, in an embodiment, water can be introduced into the condensation channel 211 through a cleaning water pipe to clean the condensation channel 211, or hot steam can be used to melt and clean the grease in the condensation channel 211 through a steam pipe, thereby improving the cleaning flexibility of the condensation channel 211 and improving the cleaning effect while reducing costs.

[0083] For example, when cleaning the condensation channel 211, the hot steam generated by the steam generating device 41 can be first introduced into the condensation channel 211, and the hot steam will melt the grease in the condensation channel 211, thereby reducing the adhesion of the grease in the condensation channel 211; then, the steam generating device 41 is stopped, and water is introduced into the condensation channel 211 through the cleaning water pipe, so that the melted grease in the condensation channel 211 can be flushed, thereby improving the cleaning effect of the condensation channel 211.

[0084] It is worth noting that during the cleaning process, the heat dissipation fan 23 stops running to reduce the dissipation of hot steam in the condensation channel 211.

[0085] In this embodiment, the outlet end of the steam pipe is connected to the cleaning water pipe to simplify the structure. The inlet end of the steam pipe is connected to the steam supply pipeline through a three-way valve to achieve selective opening and closing of the steam supply pipeline and the steam pipe.

[0086] The connection between the cleaning water pipe and the water inlet pipe 42 or the water tank 43 can be set up with reference to the first embodiment, and will not be repeated here.

[0087] Example 3

[0088] This embodiment provides a cooking device, and the cooking device provided in this embodiment is basically the same as the cooking device provided in the above embodiment, with only some settings being different. This embodiment will no longer repeat the structures that are the same as those in the above embodiment.

[0089] like Figure 6As shown, in this embodiment, a water supply chamber 431 and a wastewater chamber 432 are arranged side by side in the water tank 43, the water inlet end of the water inlet pipe 42 is connected to the water supply chamber 431, and the water outlet end of the drain pipe 32 is connected to the wastewater chamber 432, so that the condensed water or cleaning water discharged from the condensation channel 211 is discharged into the wastewater chamber 432 through the water collecting box 31 and the drain pipe 32 in turn.

[0090] In this embodiment, the wastewater chamber 432 and the water supply chamber 431 are connected through a water port, and a grease filter structure 433 is provided at the water port. As a result, water in the wastewater chamber 432 can flow to the water supply chamber 431 through the grease filter structure 433, allowing the water in the reflux chamber to be filtered before flowing to the water supply chamber 431, reducing the grease content in the water in the water supply chamber 431, thereby preventing grease from clogging the water inlet pipe 42 and ensuring water supply reliability. Furthermore, this arrangement can recycle condensed water formed in the condensation channel 211 during the cooking process, saving water resources. It can also circulate cleaning water during the cleaning process, improving the cleaning effect of the condensation channel 211. The grease filter structure 433 can be, but is not limited to, a filter.

[0091] In other embodiments, the water supply chamber 431 and the waste water chamber 432 are separated, thereby preventing condensed water or cleaning water from contaminating the water supply chamber 431 and ensuring the cleanliness of the water inlet pipe 42 of the steam generating device 41.

[0092] The water tank 43 includes a box body with an open top and a box cover provided at the open top. The reflux chamber and the water supply chamber 431 are arranged side by side in the box body. Pull-out chutes are provided on the opposite side walls of the box body. The pull-out chutes are provided upwardly through the box body. The opposite sides of the grease filter structure 433 can be vertically pulled out and arranged in the pull-out chutes. This arrangement enables the grease filter structure 433 to be installed and removed from the box body by pulling, thereby facilitating the disassembly and cleaning of the grease filter structure 433. At least two grease filter structures 433 are provided at intervals along the extension direction of the box body, thereby achieving multi-channel filtration from the reflux chamber to the water supply chamber 431, thereby improving the grease filtration effect. Furthermore, ribs 434 are provided on the front and rear side walls of the box body, and pull-out chutes are provided on the ribs 434.

[0093] The remaining structures of the water tank 43, the mounting structure of the water tank 43 on the machine body, and the connection structure between the water tank 43 and the pipeline can be set with reference to the existing technology and will not be described in detail here.

[0094] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
