Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen equipment, and in particular to a steam condensing device for a cooking device and a cooking device. BACKGROUND

[0002] With the continuous improvement of people's living standards, cooking devices with multiple cooking functions have gradually become essential cooking devices in people's kitchens.

[0003] At present, cooking devices with steam functions such as steam ovens and steam oven combination machines are widely used in household kitchens, catering industries and food processing fields. In the cooking process, the cooking device realizes the steaming of food through steam heating, but the generation and condensation process of steam is accompanied by the release of a large amount of water vapor. Especially in low-temperature environments such as winter, the high-temperature steam generated during the operation of the device rapidly condenses in the device shell or the surrounding air, forming a large amount of visible water mist or droplets. This not only reduces the dryness of the device surface, causing the operation area to be slippery, but also may cause the indoor humidity to increase sharply due to the exhaust of steam, affecting the user's sensory experience of the cooking device.

[0004] In existing cooking devices, steam can be condensed by a condensing device, which usually adopts a combination of a fan and fins. Specifically, the forced air flow in the condensing cavity transfers the heat generated by the condensation of steam to the surface of the fins, and then heat is dissipated through air convection. However, the existing condensing device relies on the passive heat dissipation method of the fan and fins, which cannot quickly condense steam into liquid, resulting in a large amount of steam exhaust, affecting the device operating environment and user experience. In addition, the condensate is directly discharged to the outside of the device, which cannot be recycled, causing waste of resources and increasing user cleaning and maintenance costs. SUMMARY

[0005] The present application provides a steam condensing device for a cooking device and a cooking device. By setting a condensing shell containing cooling liquid and continuously cooling the cooling liquid by a refrigeration assembly, the cooling liquid is kept in a low-temperature state. The condensing pipeline in the condensing shell is in a spiral bending structure from top to bottom, which greatly increases the contact area and contact time with the cooling liquid, so that the high-temperature steam is fully heat exchanged and quickly condensed, significantly improving the condensing efficiency, avoiding steam exhaust, and facilitating condensate collection and recycling.

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] As described in the background section, existing cooking equipment uses a condenser to condense steam, typically employing a combination of a fan and fins. Specifically, a fan forces airflow within the condensation chamber, transferring the heat generated by steam condensation to the fin surface, where heat is then dissipated through air convection. However, existing condenser systems rely on this passive cooling method of fans and fins, which cannot quickly condense steam into a liquid state, resulting in significant steam emissions that negatively impact the equipment's operating environment and user experience. Furthermore, the condensate is directly discharged to the outside of the equipment, cannot be recycled, wastes resources, and increases cleaning and maintenance costs for users.

[0049] To address the aforementioned technical problems, the first aspect of this application provides a steam condensation device for cooking equipment. This steam condensation device includes a condensation shell, a refrigeration component, and a condensation pipe. The condensation shell has a condensation chamber containing coolant. The refrigeration component is fitted to the bottom of the condensation shell and is used to cool the coolant. The condensation pipe is disposed within the condensation chamber and is spirally bent from top to bottom within the condensation chamber to increase the contact area with the coolant. The condensation pipe has a first end and a second end, with the first end positioned higher than the second end. The first end is used to connect to the inner pot of the cooking equipment to introduce steam, and the second end is used to discharge the condensed liquid. Thus, the steam condensation device provided in this application, by setting up a condensation shell containing coolant and utilizing the refrigeration component to continuously cool the coolant, keeps the coolant at a low temperature. The spirally bent structure of the condensation pipe within the condensation shell significantly increases the contact area and contact time with the coolant, allowing for sufficient heat exchange and rapid condensation of the high-temperature steam, significantly improving condensation efficiency, preventing steam exhaust, and facilitating the collection and recycling of condensate.

[0050] A second aspect of this application provides a cooking apparatus. The cooking apparatus includes an inner pot and the aforementioned steam condensing device. The inner pot has an air inlet. The condensation pipe of the steam condensing device is connected to the air inlet of the inner pot via an air inlet pipe to form a steam passage.

[0051] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0052] This application provides a steam condensation device and a cooking device for cooking equipment. By setting up a condenser shell containing coolant and using a refrigeration component to continuously cool the coolant, the coolant is kept at a low temperature. The condensation pipes inside the condenser shell have a spiral bending structure from top to bottom, significantly increasing the contact area and contact time with the coolant, allowing for sufficient heat exchange and rapid condensation of high-temperature steam, significantly improving condensation efficiency, preventing steam leakage, and facilitating the collection and recycling of condensate. The specific structure of the steam condensation device and the cooking device provided in this application will be described below with reference to the accompanying drawings.

[0053] refer to Figure 1 as well as Figure 2In a first aspect, this application provides a steam condensation device 100 for a cooking appliance 700. Wherein, as... Figure 3 As shown, the steam condensation device 100 may include a condenser housing 200. The condenser housing 200 may have a condenser chamber 210, and the condenser chamber 210 may contain a coolant.

[0054] Continue to refer to Figure 3 Based on the above embodiments, the steam condensation device 100 may further include a refrigeration component 300. In one possible implementation, the refrigeration component 300 may be fitted to the bottom of the condensation housing 200, thereby enabling the refrigeration component 300 to cool the coolant.

[0055] Continue to refer to Figure 2 as well as Figure 3 Based on the above embodiments, the steam condensing device 100 may further include a condensing pipe 400. The condensing pipe 400 may be disposed within the condensing chamber 210. In this embodiment, the condensing pipe 400 is spirally bent from top to bottom within the condensing chamber 210, thereby increasing the contact area with the coolant. In one possible implementation, the condensing pipe 400 may have a first end 410 and a second end 420, with the height of the first end 410 being higher than the height of the second end 420. The first end 410 may be used to connect to the inner pot 800 of the cooking appliance 700, thereby introducing steam into the condensing pipe 400. The second end 420 may be used to discharge the condensed liquid.

[0056] The steam condensation device 100 provided in this application embodiment provides a condensation shell 200 containing coolant and uses a refrigeration component 300 attached to the bottom of the shell to continuously cool the coolant, so that the coolant is kept at a low temperature.

[0057] Furthermore, the condenser pipe 400 connecting the inner liner 800 of the cooking equipment 700 is arranged in a spiral bend from top to bottom within the condenser chamber 210. This allows the high-temperature steam to fully exchange heat with the external coolant during its flow through the condenser pipe 400, thus rapidly condensing into liquid. The spiral structure of the condenser pipe 400 significantly increases the effective contact area and contact time between steam and coolant, significantly improving condensation efficiency. It effectively prevents steam from escaping and enables rapid liquefaction and collection of steam, which is beneficial for water resource recycling.

[0058] In the embodiments of this application, it is understood that the height of the first end 410 of the condensing pipe 400 is higher than the height of the second end 420 of the condensing pipe 400, thereby forming a natural flow direction, which facilitates the discharge of liquid by gravity after steam condensation. The layout of high inlet and low outlet utilizes gravity to promote the discharge of condensate, requiring no additional power and featuring a simple and reliable structure.

[0059] Continue to refer to Figure 2 as well as Figure 3 Based on the above embodiment, the condensing pipe 400 has a multi-layered parallel spiral segment structure within the condensing chamber 210. Specifically, along the side view of the condensing shell 200, each spiral segment of the condensing pipe 400 can be arranged horizontally in parallel, with consistent spacing between adjacent spiral segments. It can be understood that this arrangement allows the condensing pipe 400 to form a regular and dense meandering path within a limited space, further increasing the contact area between the pipe wall and the coolant, and enhancing the heat exchange effect.

[0060] In one possible implementation, the first end 410 and the second end 420 of the condensing pipe 400 are vertically offset, resulting in a downward spiral shape for the condensing pipe 400, allowing steam to flow downwards within it. It is understood that by offsetting the first end 410 and the second end 420, gravity forces the condensed liquid to flow downwards and drain naturally, preventing condensate from accumulating and clogging the condensing pipe 400, thus ensuring a smooth steam passage and the continuity of the condensation process.

[0061] Continue to refer to Figure 2 as well as Figure 3 Based on the above embodiments, the condenser shell 200 may be provided with a steam inlet 220 and a condenser outlet 230. The steam inlet 220 is correspondingly disposed with the first end 410 of the condenser pipe 400, thereby connecting the first end 410 of the condenser pipe 400 to the steam inlet 220. Correspondingly, the condenser outlet 230 is correspondingly disposed with the second end 420 of the condenser pipe 400, thereby connecting the second end 420 of the condenser pipe 400 to the condenser outlet 230.

[0062] In one possible implementation, the height of the condenser outlet 230 can be lower than the height of the steam inlet 220. This high-low design creates a natural height difference, which not only facilitates steam entering the condenser pipe 400 by pressure difference but also ensures that the condensed liquid can automatically discharge from the lower-positioned condenser outlet 230 under gravity, eliminating the need for an additional power unit and resulting in a simple and reliable structure. Furthermore, when the liquid level in the condenser chamber 210 rises, the condensate in the condenser chamber 210 can preferentially flow to the second end 420, thereby flowing out of the condenser outlet 230 and preventing condensate from flowing back into the inner liner 800.

[0063] Continue to refer to Figure 2 Based on the above embodiments, the steam condensation device 100 may further include: a return pipe 500. Wherein, combined with Figure 5 As can be seen, one end of the return pipe 500 can be connected to the second end 420 of the condenser pipe 400 through the condenser outlet 230, while the other end of the return pipe 500 can be connected to the water inlet pipe 720 of the cooking equipment 700. By setting up the return pipe 500, the condensed water obtained after condensation can be recovered and guided to the water inlet pipe 720 of the cooking equipment 700, realizing the recycling of water resources, reducing the overall water consumption of the cooking process, and achieving the effect of energy saving and environmental protection.

[0064] Continue to refer to Figure 2 as well as Figure 3 Based on the above embodiments, the steam condensation device 100 may further include an exhaust pipe 510. In one possible implementation, an exhaust port 240 may be provided at the top of the condensation housing 200. Alternatively, the exhaust port 240 may be located at other positions within the condensation housing 200; this embodiment is not limited thereto. In this embodiment, one end of the exhaust pipe 510 can be connected to the condensation chamber 210 via the exhaust port 240, while the other end of the exhaust pipe 510 can be connected to the air outlet 730 of the cooking device 700.

[0065] Understandably, the exhaust pipe 510 can promptly remove any small amount of uncondensed gas or air that may accumulate in the condensation chamber 210 and discharge the gas along the air outlet 730 of the cooking equipment 700, preventing the gas from creating pressure in the condensation chamber 210 and affecting the condensation efficiency, and also ensuring the internal pressure balance and stable operation of the steam condensation device 100.

[0066] refer to Figure 4 Based on the above embodiments, the refrigeration assembly 300 may include: a refrigeration element 310, a heat-conducting element 320, and heat dissipation fins 330. The cold end of the refrigeration element 310 may be connected to the bottom wall of the condenser housing 200, while the heat-conducting element 320 may be disposed between the cold end of the refrigeration element 310 and the bottom wall of the condenser housing 200. The hot end of the refrigeration element 310 may be connected to the heat dissipation fins 330.

[0067] In one possible implementation, for example, the cooling component 310 can be a semiconductor cooling chip, and the heat-conducting component 320 can be thermal grease or a metal sheet; this embodiment is not limited thereto. In this embodiment, the heat-conducting component 320 can effectively reduce contact thermal resistance and improve the heat transfer efficiency from the cold end of the cooling component 310 to the condenser housing 200 and the coolant. Additionally, the heat dissipation fins 330 increase the heat dissipation area of ​​the hot end of the cooling component 310. The optimized structure of the cooling assembly 300 improves the heat conduction path, resulting in higher cooling efficiency and more stable operation.

[0068] Continue to refer to Figure 3 Based on the above embodiments, the steam condensation device 100 may further include an air duct assembly 600. The air duct assembly 600 may further include an air duct structure 610 and a cooling fan 620. In one possible implementation, one end of the air duct structure 610 may be connected to the cooling fan 620, while the other end of the air duct structure 610 may be connected to the air outlet 730 of the cooking device 700, and at least a portion of the air duct structure 610 may be located below the condensation housing 200.

[0069] Alternatively, the cooling fan 620 can be located at the rear of the condenser housing 200. It is understood that the cooling fan 620 can be used to drive cooling airflow through the heat dissipation fins 330 of the refrigeration assembly 300 and achieve forward exhaust through the air outlet 730.

[0070] In this embodiment, the air duct assembly 600 provides forced convection cooling for the heat dissipation fins 330 of the cooling assembly 300. The airflow efficiently removes heat, significantly improving the heat dissipation performance of the cooling component 310, thereby ensuring the continuous cooling capacity of the cooling assembly 300. Simultaneously, combining the heat dissipation air duct with the air outlet 730 of the cooking device 700 achieves integrated system heat dissipation and device exhaust, simplifying the overall structural layout of the cooking device 700.

[0071] Continue to refer to Figure 3 Based on the above embodiments, the air duct structure 610 may further include a heat dissipation air duct cover plate 611 and a heat dissipation air duct base plate 612. In one possible implementation, the heat dissipation air duct cover plate 611 and the heat dissipation air duct base plate 612 may form an air duct cavity 613. The air duct cavity 613 allows cooling airflow to pass through, and the heat dissipation fins 330 may be located within the air duct cavity 613, and the heat dissipation fins 330 may also be connected to the heat dissipation air duct cover plate 611. Thus, the air duct cavity 613 formed by the combination of the heat dissipation air duct cover plate 611 and the heat dissipation air duct base plate 612 can constrain and guide the airflow to flow in a concentrated and orderly manner across the surface of the heat dissipation fins 330, reducing airflow eddies and leakage, improving the utilization efficiency of the cooling airflow, and enhancing the heat dissipation effect.

[0072] refer to Figure 1 as well as Figure 2 In a second aspect, this application provides a cooking apparatus 700. The cooking apparatus 700 may include an inner pot 800 and the aforementioned steam condensing device 100. The inner pot 800 may have an air inlet 810. The condensing pipe 400 of the steam condensing device 100 can be connected to the air inlet 810 of the inner pot 800 via an air inlet pipe 820, thereby forming a steam passage.

[0073] In this way, by efficiently integrating the steam condenser 100 with the inner liner 800, the cooking equipment 700 can quickly introduce and condense the large amount of steam generated when cooking food, effectively preventing steam from overflowing from gaps in the door of the cooking equipment 700, keeping the kitchen environment dry and clean, improving the user experience, and also laying the foundation for the recycling of condensate.

[0074] refer to Figure 5 Based on the above embodiments, the cooking device 700 may further include a valve 710 and a water inlet pipe 720. The return pipe 500 of the steam condenser 100 can be connected to the water inlet pipe 720 via the valve 710.

[0075] In one possible implementation, valve 710 is a multi-port connection device for controlling gas flow. Exemplarily, valve 710 can be a three-way valve, but this application is not limiting in its embodiments.

[0076] Continue to refer to Figure 5 Based on the above embodiments, valve 710 is used as an example of a three-way valve. Valve 710 may have a first port 711, a second port 712, and a third port 713, and the water inlet pipe 720 may include a first water inlet pipe 721 and a second water inlet pipe 722. In this embodiment, the first port 711 of valve 710 may be connected to the first water inlet pipe 721, the second port 712 of valve 710 may be connected to the second water inlet pipe 722, and the third port 713 of valve 710 may be connected to the return pipe 500 of the steam condensing device 100.

[0077] Specifically, the first port 711, the second port 712, and the third port 713 of the valve 710 are connected to the first water inlet pipe 721, the second water inlet pipe 722, and the return pipe 500, respectively, so that condensate can be collected from the return pipe 500 into the water inlet pipe 720 through the valve 710.

[0078] In the embodiments of this application, it is understood that the water circuit can be flexibly controlled by setting the multi-way valve 710. External water can be introduced into the cooking equipment 700 through the inlet pipe 720, or the water recovered from the condensation device can be introduced into the cooking equipment 700 for reuse. This achieves water resource recycling and further optimizes the water-saving performance and functional integration of the cooking equipment 700.

[0079] Continue to refer to Figure 2 as well as Figure 5 Based on the above embodiments, the cooking device 700 may further include a water pump 740 and a water tank 750. Both the water pump 740 and the water tank 750 may be located at the top of the inner liner 800. In this embodiment, referring to the figures, one end of the water pump 740 may be connected to the water tank 750, while the other end of the water pump 740 may be connected to the first water inlet pipe 721.

[0080] In this embodiment, it is understood that the water tank 750 is used to store water and is powered by the water pump 740 to pressurize the water into the first inlet pipe 721. The water pump 740 and the water tank 750 work together to provide a stable and controllable water source and power for the entire water circulation system, ensuring the normal operation of functions such as steam generation, humidification, or cooling compensation.

[0081] Continue to refer to Figure 5 Based on the above embodiments, the cooking device 700 may further include a steam system assembly 760. The steam system assembly 760 may be located at the rear of the inner pot 800. In this embodiment, one end of the steam system assembly 760 may be connected to the inner pot 800, and the other end of the steam system assembly 760 may be connected to the second water inlet pipe 722.

[0082] Understandably, the steam system component 760 is connected to the second water inlet pipe 722, allowing condensate to flow directly back to the steam system component 760 for steam generation, thus achieving internal recycling of water resources. The integrated design of the steam system component 760 enables multi-purpose utilization of condensate, improving the overall resource efficiency of the cooking equipment 700.

[0083] In this embodiment, the steam condensation device 100 provided in this application provides a condensation shell 200 containing coolant and uses a refrigeration component 300 to continuously cool the coolant, keeping the coolant at a low temperature. The condensation pipe 400 inside the condensation shell 200 has a spiral bending structure from top to bottom, which greatly increases the contact area and contact time with the coolant, allowing high-temperature steam to fully exchange heat and condense quickly, significantly improving condensation efficiency, preventing steam from being discharged, and facilitating the collection and recycling of condensate.

[0084] The cooking appliance 700 provided in this embodiment employs a steam condensation device 100, which condenses the large amount of steam generated during cooking, preventing steam from escaping and improving condensation efficiency and user experience. Furthermore, the recycling of condensate can increase the operating time of the water tank 750.

Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0087] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0088] It should be readily understood that “on,” “above,” and “on top of” in this disclosure should be interpreted in the broadest manner, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0089] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90 degrees or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0090] Finally, it should be noted that other embodiments of this application will readily conceive of by those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and alterations may be made without departing from its scope.
