[0047] The cooking device provided by the embodiment has the condenser pipe 11 extending downward from the air inlet end to the air outlet end, and the water collecting box 13 is arranged below the condenser pipe 11, so that the condensed water formed in the condenser pipe 11 can automatically flow into the water collecting box 13 under the action of gravity, improving the convenience of recycling the condensed water; the water outlet end of the reflux pipe 15 is connected with the water supply channel of the steam generator, so that the condensed water formed can be used for water supply of the steam generator, thereby realizing recycling of the condensed water, saving water resources, reducing cost, and without frequent cleaning of the water collecting box 13, thereby reducing the use difficulty of the cooking device and improving the position design flexibility of the water collecting box 13 and the condenser pipe 11; in addition, by arranging the reflux control valve 16 on the reflux pipe 15, the timing of the condensed water in the water collecting box 13 flowing to the water supply channel can be controlled, so that in some scenes or cooking stages that are not conducive to steam supply using the reflux condensed water, the condensed water can be temporarily stored in the water collecting cavity, further improving the use convenience and reliability of the cooking device; since the reflux pipe 15 is arranged horizontally from the water inlet end to the water outlet end or has a downward extending trend, the flow of the condensed water to the water supply channel is also facilitated by the water flow gravity, thereby realizing recycling of the condensed water without additional power, reducing cost.
[0048] The water supply channel includes the water tank 2, the water inlet pipe 5 and the water pump 6. The water inlet pipe 5 is connected between the water inlet of the steam generator and the inner cavity of the water tank 2, and the water pump 6 is arranged between the water tank 2 and the steam generator for pumping the water in the water tank 2 into the steam generator.

The structure of the water tank 2 and the mounting structure of the water tank 2 on the base 4 can be arranged according to the prior art, which is not the focus of the present application and will not be described herein.
[0049] The water outlet end of the reflux pipe 15 is connected with the inner cavity of the water inlet pipe 5 or the water tank 2. By connecting the water outlet end of the reflux pipe 15 with the inner cavity of the water inlet pipe 5 or the water tank 2, the connection convenience of the reflux pipe 15 and the water supply channel is improved. In the embodiment, the water outlet end of the reflux pipe 15 is connected with the water inlet pipe 5, thereby reducing the connection of the pipe and the water tank 2, facilitating the taking and placing of the water tank 2, and improving the cleaning and use convenience of the water tank 2.
[0050] The water inlet pipe 5 comprises a tee joint 52 and a water inlet main pipe 51, the water inlet end of the water inlet main pipe 51 is connected with the first port of the tee joint 52, the water outlet end is connected with the water inlet port of the steam generating device, the water outlet end of the backflow pipe 15 is detachably connected with the second port of the tee joint 52, the third port of the tee joint 52 is connected with the water tank 2, the water pump 6 is arranged on the water inlet main pipe 51, and the backflow control valve 16 is arranged on the backflow pipe 15. By arranging the tee joint 52, the connection convenience of the backflow pipe 15 and the water inlet pipe 5 is improved; at the same time, the detachable connection of the backflow pipe 15 and the tee joint 52 is also beneficial to the assembly and disassembly of each component, and the maintenance and repair cost is reduced.
[0051] In the embodiment, the tee joint 52 is integrally formed with the water inlet main pipe 51, so as to simplify the processing of the water inlet pipe 5, reduce the assembly difficulty of the water inlet pipe 5, and reduce the probability of water leakage. In other embodiments, the tee joint 52 can be detachably connected or welded with the water inlet main pipe 51.
[0052] In the embodiment, the water inlet main pipe 51 is arranged higher than the tee joint 52, so that when the water pump 6 is not working and the backflow control valve 16 is opened, the condensed water in the backflow pipe 15 can flow to the water tank 2 through the tee joint 52, the condensed water is cleaned, the convenience and reliability of the condensed water cleaning are improved.
[0053] It is worth noting that in the embodiment, the connection structure of the water inlet pipe 5 and the water tank 2 can be arranged according to the prior art, which is not the focus of the present application, and will not be described here.
[0054] Further, the second port is provided with a grease filtering structure 24 to filter the condensed water passing through the second port, so as to reduce the amount of grease in the water supply channel, reduce the probability of the water supply channel being blocked, and improve the cooking experience. The grease filtering structure 24 preferably adopts a filter screen.
[0055] In the embodiment, the condensing pipe 11 and the water collecting box 13 are installed on the back side of the inner container 3, so that the main structure of the steam condensing assembly 1 is located on the back side of the inner container 3, the size of the cooking equipment in the left-right direction is reduced, the structural compactness is improved, and the miniaturization of the cooking equipment is facilitated. The backflow pipe 15 and the backflow control valve 16 are arranged between the bottom of the inner container 3 and the base 4.
[0056] The reflux pipe 15 comprises a vertical pipe section 151 and a horizontal pipe section 152.

The horizontal pipe section 152 has a water inlet end connected with the lower end of the vertical pipe section 151 and a water outlet end connected with the water supply pipeline. The horizontal pipe section 152 is horizontally arranged or extends downwardly from the water inlet end to the water outlet end. The structure of the reflux pipe 15 facilitates the installation of the reflux pipe 15 at the bottom of the inner container 3 and facilitates the connection of the reflux pipe 15 with the water collecting box 13 and the flow of the condensed water from the water collecting cavity to the reflux pipe 15.
[0057] The reflux control valve 16 is connected in series in the horizontal pipe section 152 and detachably connected with the horizontal pipe section 152, thereby facilitating the disassembly, maintenance and replacement of the reflux control valve 16. The reflux control valve 16 is preferably an electromagnetic valve and is communicatively connected with the controller. Further, the horizontal pipe section 152 is arranged in an L shape and has a portion extending from back to front and another portion extending in the left-right direction, thereby facilitating the connection of the horizontal pipe section 152 with the water inlet joint and reducing the requirement for the arrangement position of the water collecting box 13.
[0058] Since the hot steam may not be completely condensed in the condensing pipe 11, part of the steam enters the water collecting box 13 through the condensing pipe 11. To avoid the influence of the large air pressure in the water collecting box 13 on the use of the water collecting box 13, the top of the water collecting box 13 is provided with a balance air hole which is connected with the water collecting cavity, so that the gas in the water collecting cavity can be discharged through the balance air hole, thereby balancing the air pressure in the water collecting cavity. Further, a balance air pipe 14 is installed at the balance air hole. The gas outlet end of the balance air pipe 14 is connected with the external environment, thereby better controlling the position of the discharge of the gas in the water collecting cavity.
[0059] To improve the condensing and cooling effect of the steam in the condensing pipe 11, the condensing pipe 11 comprises a plurality of condensing sections arranged in an upper-lower interval. The condensing sections extend in the transverse direction and are connected with each other through elbow sections, so that the condensing pipe 11 is arranged in a serpentine shape by being bent from top to bottom. In this way, the length of the condensing pipe 11 is increased without changing the height of the condensing pipe 11 in the vertical direction, thereby improving the condensing effect.
[0060] Further, the condensing pipe 11 is arranged in an interval in the transverse direction. The water inlet end of each condensing pipe 11 is connected with the cooking cavity and the water outlet end is connected with the water collecting box 13, thereby improving the condensing effect of the steam in the steam condensing assembly 1 while reducing the length of the single condensing pipe 11. In this embodiment, the arrangement direction of the plurality of condensing pipes 11 is substantially perpendicular to the extension direction of the condensing sections.
[0061] To improve the convenience of connecting the condensing pipe 11 and the water collecting box 13, the steam condensing assembly 1 further comprises an adapter pipe 18 extending from top to bottom and connected with the lower end of the condensing pipe 11 at the upper end, and the lower end of the adapter pipe 18 is connected with the water collecting box 13, so as to reduce the requirement for the relative position of the condensing pipe 11 and the water collecting box 13. The adapter pipe 18 is detachably connected with the water collecting box 13 and the condensing pipe 11. Further, the adapter pipe 18 is a flexible pipe, so as to further ensure the reliability of the connection between the condensing pipe 11 and the water collecting box 13.
[0062] To further improve the condensing effect, the steam condensing assembly 1 further comprises a heat sink 12, which comprises a plurality of heat dissipation fins arranged side by side and spaced apart in the transverse direction, and a vertical heat dissipation channel is formed between adjacent two heat dissipation fins. Each condensing section passes through all the heat dissipation fins, so that the heat dissipation fins can enhance the heat dissipation of the condensing pipe 11, thereby ensuring the condensing effect of the condensing pipe 11. In the embodiment, the heat dissipation fins are arranged in the front-rear direction, and the plurality of condensing pipes 11 are arranged in the left-right direction.
[0063] To improve the convenience of installing the heat sink 12 and the condensing pipe 11, the cooking device further comprises an air duct support 7 installed between the inner container 3 and the cabinet and connected with the inner container 3 and / or the cabinet. The heat sink 12 is installed on the side of the air duct support 7 away from the inner container 3, and the air duct support 7 has a cavity inside. By providing the air duct support 7, support can be provided for the installation of the heat sink 12, improving the convenience of installing the heat sink 12. At the same time, the cavity is also beneficial to reducing the conduction of heat from the inner container 3 to the heat sink 12, thereby better ensuring the condensing and heat dissipation effect of the steam.
[0064] The lower end of the air duct support 7 is spaced apart from the base 4, and a mounting seat 8 is connected between the air duct support 7 and the base 4. The water collecting box 13 is detachably mounted on the mounting seat 8, thereby improving the stability and reliability of the water collecting box 13. The lower end of the mounting seat 8 is provided with a relief hole for the reflux pipe 15 to pass through.
[0065] The water collecting box 13 comprises a box body, an upper pipe portion protruding from the upper end of the box body, and a lower pipe portion protruding from the lower end of the box body. The inner cavity of the box body forms a water collecting cavity, and the inner cavities of the upper pipe portion and the lower pipe portion are in communication with the water collecting cavity. The lower end of the adapter pipe 18 is sealingly inserted and fitted with the upper pipe portion, and the water inlet pipe 5 of the reflux pipe 15 is interference-fitted with the lower pipe portion. Thus, the assembly convenience of the water collecting box 13, the condensing pipe 11 and the reflux pipe 15 can be improved, and the disassembly and assembly convenience of the water collecting box 13 can be improved. The bottom of the box body is concave downward to form a water collecting groove, and the lowest part of the water collecting groove forms a water outlet. The reflux pipe 15 is connected to the water outlet, so as to guide the condensed water in the water collecting cavity to flow into the reflux pipe 15.
[0066] Further, the box body has mounting plate portions outwardly protruding from opposite sides in the transverse direction, and the mounting plate portions are detachably connected to the mounting seat 8. Specifically, the mounting plate portions are connected to the mounting seat 8 by fastening screws penetrating through the mounting plate portions and the mounting seat 8, and the fastening screws are preferably arranged at least two in number and spaced apart along the extension direction of the mounting plate portions.
[0067] The steam condensing assembly 1 further comprises a fan assembly 17, which comprises a fan cover 171, an impeller 173 and a driving motor 172. The fan cover 171 has an air inlet, an air cavity and an air outlet in sequence, and the condensing pipe 11 is arranged opposite to the air outlet. The impeller 173 is rotatably installed in the air cavity, and the driving motor 172 is installed on the fan cover 171 and connected to the impeller 173 to drive the impeller 173 to rotate, so that the rotation of the impeller 173 drives the external cooling airflow to flow through the air inlet, the air cavity and the air outlet in sequence to the condensing pipe 11, thereby cooling the radiator 12 and the condensing pipe 11 and ensuring the condensing effect of the condensing pipe 11. The fan cover 171 is installed on the air duct support 7.
[0068] Other structures of the cooking device can be arranged according to the prior art, which is not the focus of the present application and will not be described herein.
