[0044] An embodiment of the present invention provides a cooking device having a steam cooking function and capable of condensing and cooling steam during or after cooking, thereby reducing steam emission and improving the user experience of the cooking device.

[0045] The cooking device provided in this embodiment includes a machine body, a steam cooking module and a controller.

[0046] like Figures 1 to 5 As shown, in order to realize condensation and cooling of the hot steam discharged from the cooking cavity, in this embodiment, the cooking device further includes a steam condensation device, which includes a flow guide component 1, a cleaning water pipe 6 and a condensation component 2. The flow guide component 1 has a flow channel, a steam inlet 1113, an outlet 1131 and a water inlet 1121, and the outlet 1131 can be connected to the steam inlet 1113 or the water inlet 1121 through the flow channel, so that the flow guide component 1 is in a corresponding exhaust state where the steam inlet 1113, the flow channel and the outlet 1131 are connected in sequence, or the flow guide component 1 is in a corresponding cleaning state where the water inlet 1121, the flow channel and the outlet 1131 are connected in sequence; the water outlet end of the cleaning water pipe 6 is connected to the water inlet 1121, and the water inlet end is used for water intake; the condensation component 2 has a condensation channel 211, and the air inlet of the condensation channel 211 is connected to the outlet 1131.

[0047] The steam condensation device provided in this embodiment has a steam inlet 1113, a flow channel and an exhaust port 1131 connected in sequence in the flow guide component 1. When the hot steam in the cooking cavity needs to be discharged, the hot steam can flow into the condensation channel 211 through the steam inlet 1113, the flow channel and the exhaust port 1131 in sequence, so that the hot steam is condensed and cooled in the condensation channel 211, thereby reducing the steam discharge amount and the steam discharge temperature. The flow guide component 1 has a cleaning state in which the water inlet 1121, the flow channel and the exhaust port 1131 are connected in sequence. The water outlet end of the cleaning water pipe 6 is connected to the water inlet 1121, so that water can be supplied to the cleaning water pipe 6, and the water can flow into the condensation channel 211 through the water inlet 1121, the flow channel and the discharge port 1131 in sequence, so as to clean the condensation channel 211 and reduce the accumulation of grease in the condensation channel 211, thereby ensuring the smoothness of the exhaust of the condensation channel 211 after long-term use, and further ensuring the condensation and cooling effect of the steam condensation device on the steam, and at the same time, it can also slow down or avoid the growth of bacteria in the condensation channel 211, thereby improving the user experience of the steam condensation device.

[0048] like Figure 1 and Figure 2 As shown, the steam cooking module 4 includes a steam generating device 41 and a water supply component, the water supply component is used to supply water to the water inlet port of the steam generating device 41, and the water entering the steam generating device 41 is heated to form hot steam and supplied to the cooking cavity. In this embodiment, the steam generating device 41 is a steam generator arranged outside the inner tank component 5. In other embodiments, the steam generating device 41 can also be an evaporation plate arranged at the bottom of the cooking cavity. The specific structure of the steam generating device 41 and the installation structure on the inner tank component 5 can be set with reference to the prior art, which is not the focus of this embodiment and will not be repeated here.

[0049] The water supply assembly includes a water tank 43, a water supply pipe 42 and a water pump 44. The water inlet end of the water supply pipe 42 is connected to the water tank 43, the water outlet end of the water supply pipe 42 is connected to the steam generating device 41, and the water pump 44 is arranged on the water supply pipe 42 to pump the water in the water tank 43 to the steam generating device 41. In this embodiment, the water tank 43 can be set on the front side of the base in a pull-out manner along the front-to-back direction to facilitate the taking and placing of the water tank 43. In other embodiments, the water tank 43 can also be set on the top of the inner liner assembly 5 or on the left and right sides of the inner liner assembly 5. The water tank 43 arrangement in the prior art can be applied to the present invention, and the present invention does not limit the setting position and specific structure of the water tank 43.

[0050] To simplify the structure, in the present embodiment, the water inlet end of the cleaning water pipe 6 is connected to the water supply assembly. Specifically, the water inlet end of the cleaning water pipe 6 is connected to the inner cavity of the water supply pipe 42 or the water tank 43, so that the water in the water tank 43 can be supplied to the cleaning water pipe 6, thereby improving the convenience of cleaning the condensation channel 211, and there is no need to set up a separate water supply structure for cleaning, thereby reducing costs.

[0051] In this embodiment, the water inlet end of the cleaning water pipe 6 is connected to the water supply pipe 42 and is located upstream of the water pump 44. The water supply pipe 42 is provided with a water supply control valve 45 downstream of the water pump 44. Therefore, when the guide component 1 is in the exhaust state and the water supply control valve 45 is opened, the water in the water tank 43 is supplied to the steam generating device 41; when the guide component 1 is in the cleaning state and the water supply control valve 45 is in the closed state, the water in the water tank 43 is supplied to the cleaning water pipe 6 to achieve cleaning.

[0052] In order to collect the water discharged from the condensation channel 211, in this embodiment, the steam condensation device further includes a recovery component 3, which includes a water collection box 31, which is installed below the condensation channel 211 and has a water collection cavity, and the outlet end of the condensation channel 211 is connected to the water collection cavity. Thus, the condensed water or cleaning water in the condensation channel 211 is discharged into the water collection cavity, so that the discharged water flow is collected.

[0053] Furthermore, the guide assembly 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.

[0054] In this embodiment, a drain port is provided at the bottom of the water collecting box 31, and a drain pipe 32 is connected to the drain port. The water outlet of the drain pipe 32 is connected to the water supply pipe 42 and is located upstream of the water inlet of the cleaning pipe. A drain control valve 33 is provided on the drain pipe 32. Thus, the water in the water collecting box 31 flows back to the water tank 43 and the water supply pipe 42 through the drain pipe 32, so that the condensed water or the cleaning water can be cleaned by taking and putting the water tank 43; at the same time, this arrangement allows the water to circulate in the circulating waterway formed by the water tank 43, the cleaning water pipe 6, the flow channel, the condensation channel 211, the water collecting box 31 and the drain pipe 32 when the flow guide assembly 1 is in the cleaning state, thereby improving the cleaning effect of the condensation channel 211 and saving water resources.

[0055] In another embodiment, the water outlet of the drain pipe 32 can be directly connected to the inner cavity of the water tank 43. In another embodiment, a water supply cavity and a waste water cavity are arranged side by side and separately in the water tank 43, the water inlet of the water supply pipe 42 is connected to the water supply cavity, and the water outlet of the drain pipe 32 is connected to the waste water cavity, so that the condensed water or cleaning water discharged from the condensation channel 211 is discharged to the waste water cavity through the water collecting box 31 and the drain pipe 32 in sequence, thereby avoiding the contamination of the water supply cavity by the condensed water or the cleaning water, and ensuring the cleanliness of the water supply pipe 42 of the steam generating device 41.

[0056] like Figure 4 and Figure 5 As shown, in this embodiment, the guide assembly 1 includes a shell 11 and a piston component 12, the shell 11 has a flow channel, and a steam inlet 1113, an exhaust port 1131 and a water inlet 1121 are arranged on the shell 11; the piston component 12 is slidably arranged in the flow channel and separates the flow channel into a first chamber 1111 and a second chamber 1112 with variable volume, the first chamber 1111 is connected to the steam inlet 1113, the second chamber 1112 is connected to the water inlet 1121, and the exhaust port 1131 can be connected to the first chamber 1111 or the second chamber 1112 through the sliding of the piston component 12.

[0057] That is, when the discharge port 1131 is connected to the first chamber 1111, the flow guide assembly 1 is in the exhaust state, and when the discharge port 1131 is connected to the second chamber 1112, the flow guide assembly 1 is in the cleaning state. This arrangement can control the switching of the flow guide assembly 1 between the cleaning state and the exhaust state by sliding the piston component 12, and the structure is simple and the cost is low.

[0058] The piston component 12 has a first pressure surface on the side facing the first chamber 1111, and has a second pressure surface on the side facing the second chamber 1112. The piston component 12 can move under the action of the pressure difference between the first pressure surface and the second pressure surface so that the exhaust port 1131 is connected to the first chamber 1111 or the second chamber 1112.

[0059] The above-mentioned flow guide component 1 is arranged so that when there is no steam flowing into the steam inlet 1113 and water flowing into the water inlet 1121, the pressure on the second pressure surface increases, and the piston component 12 slides in the direction toward the first chamber 1111, so that the volume of the first chamber 1111 is reduced and the volume of the second chamber 1112 is increased, thereby achieving the purpose of connecting the second chamber 1112 with the exhaust port 1131; when there is steam flowing into the steam inlet 1113 and no water flowing into the water inlet 1121, the pressure on the first pressure surface increases, and the piston component 12 moves in the direction toward the second chamber 1112 under the action of the pressure difference between the first pressure surface and the second pressure surface, so that the volume of the second chamber 1112 is reduced and the volume of the first chamber 1111 is increased, thereby achieving the purpose of connecting the first chamber 1111 with the exhaust port 1131.

[0060] That is, the configuration of the above-mentioned guide component 1 is conducive to setting the piston component 12 in the initial position, so that when water enters the water inlet 1121, the guide component 1 automatically switches to the cleaning state, and when air is taken in at the steam inlet 1113, the guide component 1 automatically switches to the exhaust state. No additional driving structure is required, the cost is low, and the reliability of water and air intake can be effectively guaranteed, thereby improving the user experience of the steam condensation device.

[0061] In another embodiment, an operating handle may be connected to the piston member 12, and the operating handle seals and passes through the housing 11 and the casing, so that the user can manually push the piston member 12 to slide through the operating handle to switch the flow guide assembly 1 between the cleaning state and the exhaust state. In another embodiment, a driving motor may also be provided to drive the piston member 12 to slide.

[0062] In this embodiment, the steam inlet 1113, the exhaust port and the water inlet 1121 are arranged in sequence at intervals along the sliding direction of the piston component 12. When no steam enters the steam inlet 1113 and no water flows into the water inlet 1121, the piston component 12 has an initial position, which is located between the steam inlet 1113 and the water inlet 1121; when the guide component 1 is in the exhaust state, the piston component 12 has an exhaust position, which is located between the exhaust port 1131 and the water inlet 1121; when the guide component 1 is in the cleaning state, the piston component 12 is in the cleaning position, which is between the exhaust port 1131 and the steam inlet 1113.

[0063] In this embodiment, when the piston component 12 is in the initial position, the piston component 12 is located between the discharge port 1131 and the water inlet 1121, so that when no water flows into the cleaning water pipe 6, the flow guide component 1 is always in the exhaust state, which can better ensure smooth exhaust. That is, the initial position is basically the same as the exhaust position.

[0064] In other embodiments, the initial position of the piston component 12 is not fixed, that is, when the guide assembly 1 is in the exhaust state and the exhaust is completed, the piston component 12 can be maintained in the exhaust position until water is introduced into the cleaning water pipe 6; when the guide assembly 1 is in the cleaning state and the cleaning is completed, the piston component 12 can be maintained in the cleaning position until steam is introduced from the steam inlet 1113.

[0065] In order to ensure that the piston component 12 is always located between the steam inlet 1113 and the water inlet 1121, in this embodiment, the guide assembly 1 includes a limiting component 14, which is used to limit the piston component 12 in the exhaust position from sliding in the direction toward the water inlet 1121, thereby avoiding steam leakage caused by the steam inlet 1113 and the water inlet 1121 being connected.

[0066] In this embodiment, in order to make the piston component 12 maintain or return to the exhaust position, the elastic member 15 causes the piston component 12 to maintain or return to the exhaust position, so that when no water flow is introduced into the second chamber 1112, the piston component 12 can slide to the exhaust position under the pressure applied by the elastic member 15 to the first pressure surface and be limited by the limiting member 14, so that the piston component 12 can stably maintain the exhaust position under the cooperation of the elastic member 15 and the limiting member 14. When water flow is introduced into the second water chamber and the pressure of the water flow on the second pressure surface overcomes the pressure of the elastic member 15 on the first pressure surface, the piston component 12 slides to the cleaning position along the direction of squeezing the first chamber 1111.

[0067] In this embodiment, the elastic member 15 is disposed in the first chamber 1111, and the first end of the elastic member 15 is fixed relative to the housing 11, and the second end of the elastic member 15 is in contact with the piston member 12, so as to simplify the structure of the flow guide assembly 1. In another embodiment, the elastic member 15 can be disposed in the second chamber 1112, and the elastic member 15 is in an extended state to apply a pulling force toward the inside of the second chamber 1112 to the piston member 12. In another embodiment, the elastic member 15 includes a first elastic member 15 disposed in the first chamber 1111 and a second elastic member 15 disposed in the second chamber 1112, the first elastic member 15 and the second elastic member 15 are both in a compressed state, and when the piston member 12 is in the exhaust position, the second elastic member 15 and the first elastic member 15 apply the same force to the piston member 12.

[0068] In this embodiment, a guide hole is opened on the inner liner assembly 5, and the piston component 12 is connected to a sliding rod 13. The extension direction of the sliding rod 13 is the same as the sliding direction of the piston component 12. The sliding rod 13 is slidably penetrated into the guide hole to provide guidance for the sliding of the piston component 12, guide the smooth sliding of the piston component 12, and avoid the piston component 12 from getting stuck due to sliding deviation during the sliding process.

[0069] A limiting component 14 is provided at one end of the slide rod 13 away from the piston component 12. The limiting component 14 is located outside the side of the guide hole away from the piston component 12 and is limited to pass through the guide hole. The limiting component 14 abuts against the inner tank assembly 5 to limit the piston component 12 from sliding in the direction of squeezing the second chamber 1112. The setting of such a limiting component 14 has a simple structure and is convenient to set up, which can simplify the structure of the housing 11 and reduce the difficulty of processing the housing 11.

[0070] In other embodiments, the limiting component 14 may be a limiting protrusion protruding from the side wall of the flow channel, and the abutment between the piston component 12 and the limiting protrusion limits the sliding of the piston component 12 in the direction toward the water inlet 1121 .

[0071] The piston component 12 is preferably detachably connected to the slide bar 13, and the piston component 12 is preferably made of elastic materials such as rubber or silicone to ensure the sealing between the first chamber 1111 and the second chamber 1112. The slide bar 13 is preferably made of metal or hard plastic to ensure sliding reliability. The limiting component 14 can be integrally formed with the slide bar 13, or can be installed on the slide bar 13 by welding or screwing.

[0072] In this embodiment, the cross section of the flow channel is circular, and the piston component 12 is a circular structure adapted to the cross section of the flow channel to improve the sliding smoothness of the piston component 12.
