Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and particularly to a combined steaming, baking and disinfection machine. Background Art

[0002] The combined steaming, baking and disinfection machine integrates three functions of steaming, baking and disinfection, which not only improves the diversity and convenience of cooking, but also increases the safety of tableware cleaning. Among them, in the steaming function, water in the water storage box is intermittently delivered to a high-temperature heating plate by a water pump to rapidly heat up and vaporize to generate water vapor, which fills the steaming and baking cavity; in the baking function, high-temperature hot air can be generated by an electric heating element to act on food materials in a circulating manner; in the disinfection function, ultraviolet rays are used for sterilization and high temperature is used for drying to ensure that tableware can be stored in a dry environment.

[0003] However, since a certain amount of steam needs to be introduced into the steaming and baking inner container during cooking, when the remaining steam after cooking cools and liquefies, the humidity of the steaming and baking inner container is relatively high; moreover, food residues will remain during the cooking process. If not cleaned in time, bacteria are likely to breed. At the same time, it is also because there is steam in the steaming and baking inner container, which is likely to cause discomfort to users when it is opened. Summary of the Invention

[0004] Based on this, it is necessary to provide a combined steaming, baking and disinfection machine, which can not only meet the sterilization and disinfection in the steaming and baking inner container, but also cool the steaming and baking inner container after cooking to reduce the impact of steam hitting the face.

The terms used in the description of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the description of this application includes any and all combinations of one or more of the related listed items.

[0034] Please refer to Figures 1 to 9 , this application provides a steaming, baking and disinfection integrated machine, including a steaming and baking inner container 11 and a disinfection inner container 12, which are arranged at intervals in a first direction. For example, they can be arranged at intervals in the left-right direction, or in the front-back direction, or in the vertical direction. In this embodiment, taking the steaming and baking inner container 11 and the disinfection inner container 12 being arranged at intervals in the left-right direction as an example. The steaming, baking and disinfection integrated machine includes a first disinfection structure 21, and the first disinfection structure 21 is arranged in the disinfection inner container 12. The first disinfection structure 21 includes a lamp tube and a lamp shade surrounding the outside of the lamp tube, and a first disinfection cavity is provided between the lamp shade and the lamp tube. The steaming, baking and disinfection integrated machine further includes a refrigeration structure 30, and the refrigeration structure 30 is arranged outside the steaming and baking inner container 11 and the disinfection inner container 12, and the refrigeration structure 30 is provided with a refrigeration cavity, and the refrigeration cavity is communicated with the first disinfection cavity and jointly defines a first flow path 101.

[0035] The steaming, baking and disinfection integrated machine has at least a first state and a second state. In the first state, the fluid power component 40 is turned on and the lamp tube is turned off. One end of the first flow path 101 is communicated with the steaming and baking inner container 11, and the other end is communicated with the external environment, and a first cooling circuit is defined. In the second state, both the fluid power component 40 and the lamp tube are turned on. The first flow path 101 is communicated with the steaming and baking inner container 11 and a first disinfection circuit is defined. The disinfection light released by the lamp tube can convert the gas flowing through the first disinfection cavity into disinfection gas.

[0036] During actual use, the steam cooking and disinfection integrated machine also has the disinfection state of the disinfection inner container 12 and the cooking state of the steaming and baking inner container 11. When only the disinfection inner container 12 is disinfected, the lamp tube is turned on to release disinfection light to the disinfection inner container 12 to meet the disinfection of tableware in the disinfection inner container 12. When only the steaming and baking inner container 11 is used for cooking, the heating plate or steam generator provided in the steaming and baking inner container 11 is turned on to bake or steam food ingredients. Of course, the disinfection operation of the disinfection inner container 12 and the cooking operation of the steaming and baking inner container 11 can be carried out simultaneously. This is only for illustrative purposes here.

[0037] Since a certain amount of steam needs to be introduced when the steaming and baking inner container 11 is cooking, especially when it is used for steaming food ingredients, steam will be generated in the steaming and baking inner container 11. After the steaming is completed, there is still steam remaining in the steaming and baking inner container 11, resulting in a relatively high humidity in the steaming and baking inner container 11. Moreover, food residues will remain in the steaming and baking inner container 11 during the cooking process. If not cleaned in time, these food residues are more likely to deteriorate in a high-humidity environment, thus breeding bacteria. At the same time, it is also because there is steam in the steaming and baking inner container 11 that when the door is opened, the steam flowing out will directly act on the user, thus causing discomfort.

[0038] In view of this, in the steam cooking and disinfection integrated machine provided in this embodiment, the first flow path 101 can be controlled to communicate with the steaming and baking inner container 11, and the fluid power component 40 is turned on to guide the air in the external environment into the first flow path 101. After being cooled by the refrigeration cavity, it flows to the steaming and baking inner container 11 to cool the steam in the steaming and baking inner container 11, thereby ensuring that there will be no discomfort caused by the steam hitting the face when the steaming and baking inner container 11 is opened. This is the first state of the steam cooking and disinfection integrated machine, that is, the refrigeration state for the steaming and baking inner container 11. At the same time, when both the fluid power component 40 and the lamp tube are turned on, the first flow path 101 and the steaming and baking inner container 11 are connected to define a first disinfection circuit. The disinfection light released by the lamp tube can convert the gas flowing through the first disinfection cavity into disinfection gas. The disinfection gas can flow along the first flow path 101, be cooled in the refrigeration cavity, and then flow to the steaming and baking inner container 11 for disinfection and freshness preservation of the steaming and baking inner container 11.

[0039] In some specific embodiments, an ultraviolet lamp for emitting ultraviolet light is provided inside the lamp tube. The lamp tube is used to transmit ultraviolet light with a wavelength of 253.7 nm and ultraviolet light with a wavelength of 185 nm. Among them, the ultraviolet light with a wavelength of 253.7 nm passes through the light-transmitting cover to irradiate the disinfection inner container 12 for disinfecting the tableware in the disinfection inner container 12. The ultraviolet light with a wavelength of 185 nm can excite the oxygen in the air in the first disinfection chamber into ozone; moreover, the excited ozone also needs to flow through the refrigeration chamber for refrigeration to maintain the ozone in a low-temperature state. Therefore, when the low-temperature ozone acts on the steaming and baking inner container 11, it not only satisfies the sterilization and disinfection in the steaming and baking inner container 11, but also can play a role in preservation. For example, during the process of putting ingredients in the steaming and baking inner container 11 for pre-ordered cooking, the ingredients stay in the steaming and baking inner container 11 for a long time and are prone to deterioration and bacterial growth. At this time, the low-temperature ozone can achieve preservation and disinfection, enabling the ingredients to be stored in the steaming and baking inner container 11 for a long time.

[0040] Among them, the fluid power component 40 adopts a blower.

[0041] Such as Figures 1 to 9 As shown, in an alternative embodiment, the refrigeration chamber and the first disinfection chamber are connected in series and jointly define a first flow path 101; the first flow path 101 has an air inlet and an air outlet, the steaming and baking inner container 11 is communicated with the air outlet, and the air inlet is also communicated with the steaming and baking inner container 11. In this way, it is beneficial for the first flow path 101 and the steaming and baking inner container 11 to jointly define a first disinfection circuit, so that the air in the steaming and baking inner container 11 can be continuously transported to the first disinfection chamber to excite ozone, thereby ensuring that the steaming and baking inner container 11 is filled with as uniform ozone as possible, improving the disinfection and sterilization effect.

[0042] Furthermore, the air inlet of the first flow path 101 can also be connected to the external environment. That is to say, the gas in the first flow path 101 can be sourced from the gas output from the steaming and baking inner container 11 or from the external environment, and the gas flow path can be selected according to different requirements, which has flexibility.

[0043] Such as Figures 1 to 4As shown, in an optional embodiment, the steaming and baking inner container 11 is connected to a first conveying pipeline 102, and the other end of the first conveying pipeline 102 is connected to the air outlet of the first flow path 101. At the same time, the steaming and baking inner container 11 is also connected to a second conveying pipeline 103, and the other end of the second conveying pipeline 103 is connected to the air inlet of the first flow path 101. In this way, the first conveying pipeline 102 and the second conveying pipeline 103 can be used to connect the steaming and baking inner container 11 and the first flow path 101, and form a first disinfection circuit for the disinfection and preservation of the steaming and baking inner container 11 itself. That is, corresponding to the second state of the steaming, baking and disinfection integrated machine. At this time, the fluid power component 40 is used to guide the gas in the steaming and baking inner container 11 to flow out along the second conveying pipeline 103 and flow to the first flow path 101, where it is cooled and converted into ozone in the first flow path 101, and then flows to the steaming and baking inner container 11 along the first conveying pipeline 102. Moreover, when the lamp tube is turned on to excite ozone, the ultraviolet light can still irradiate the disinfection inner container 12 to maintain the sterilization of the disinfection inner container 12.

[0044] Further, a first ventilation pipe 104 is provided at the air inlet, and the other end of the first ventilation pipe 104 is used to communicate with the external environment. The second conveying pipeline 103 is connected to a second ventilation pipe 105, and the other end of the second ventilation pipe 105 is used to communicate with the external environment. The second ventilation pipe 105 divides the second conveying pipeline 103 into a first section 1031 and a second section 1032, which are connected, and the first section 1031 is connected to the steaming and baking inner container 11, and the second section 1032 is connected to the air inlet of the first flow path 101. In the first state, the first ventilation pipe 104, the first flow path 101, the first conveying pipeline 102, the steaming and baking inner container 11, the first section 1031 and the second ventilation pipe 105 jointly define a first cooling circuit. That is to say, the air in the external environment flowing in through the first ventilation pipe 104 flows to the first flow path 101 under the action of the fluid power component 40 for cooling, and then flows to the steaming and baking inner container 11 along the first conveying pipeline 102 to cool the high-temperature steam in the steaming and baking inner container 11. The cooled gas flows to the first section 1031 and then flows out to the external environment through the second ventilation pipe 105. In this way, the cooling of the steaming and baking inner container 11 can be realized. At this time, the lamp tube is turned off and no ozone is generated. In the second state, the first flow path 101, the first conveying pipeline 102, the steaming and baking inner container 11 and the second conveying pipeline 103 are connected in sequence to jointly define a first disinfection circuit. At this time, the lamp tube is turned on for ozone to circulate in the steaming and baking inner container 11 to achieve disinfection and preservation.

[0045] Further, a first control valve 61 is provided on the first ventilation pipe 104, a second control valve 62 is provided on the second ventilation pipe 105, and a third control valve 63 is provided at the second section 1032 of the second delivery pipe 103. In the first state, the third control valve 63 is closed, causing the second section 1032 to be non - communicating, so that the gas flowing from the steaming and baking inner container 11 to the first section 1031 cannot flow through the second section 1032 to the inlet of the first flow path 101; and, at this time, the first control valve 61 and the second control valve 62 are opened, so that both the first ventilation pipe 104 and the second ventilation pipe 105 are communicating, and then communicating with the external environment to form a first cooling circuit. In the second state, the first control valve 61 and the second control valve 62 are both closed, and the third control valve 63 is opened to form a first disinfection circuit. When the first control valve 61 and the second control valve 62 are closed, the first ventilation pipe 104 and the second ventilation pipe 105 cannot communicate with the external environment, which is used for ozone circulation in the steaming and baking inner container 11.

[0046] Among them, the setting of each control valve is conducive to control. The control valve can adopt an electromagnetic valve, and the operation is more convenient.

[0047] Please refer to Figures 1 to 4 , as some of the exemplary ones, the disinfection inner container 12 is provided with a third delivery pipe 107 and an exhaust passage. The third delivery pipe 107 is connected to the air outlet of the first flow path 101, and the exhaust passage is used to communicate with the external environment. The steaming, baking and disinfection integrated machine also has a third state. In the third state, the first ventilation pipe 104, the first flow path 101, the third delivery pipe 107, the disinfection inner container 12 and the exhaust passage are communicating and jointly define a second cooling circuit. That is to say, the steaming, baking and disinfection integrated machine can also be used to cool the disinfection inner container 12.

[0048] It can be understood that a heating pipe is provided in the disinfection inner container 12 to dry the residual water on the tableware in the disinfection inner container 12 by using the heating pipe. These residual waters evaporate under the high - temperature baking of the heating pipe to generate steam and fill the disinfection inner container 12. Moreover, after drying, the heating pipe maintains the baking state as much as possible, which can also be used for tableware disinfection. This results in the disinfection inner container 12 being filled with high - temperature steam. If the user directly opens the disinfection inner container 12, these high - temperature steams are extremely likely to spray out, causing discomfort to the user or even scalding and other problems. At the same time, some disinfection inner containers 12 use high - temperature steam for direct drying, resulting in more high - temperature steam remaining in the disinfection inner container 12.

[0049] In view of this, in this embodiment, by setting up the second cooling circuit, low-temperature gas can be introduced into the disinfection inner container 12 to cool the steam in the disinfection inner container 12. Under the action of the fluid power component 40, the steam in the disinfection inner container 12 can be led out along with the introduced gas, so as to keep the disinfection inner container 12 in a relatively low-temperature state. Specifically, the first control valve 61 on the first air pipe 104 is opened, and the first air pipe 104 is communicated with the external environment. The gas in the external environment flows along the first air pipe 104 to the first flow path 101 under the action of the fluid power component 40. After being cooled in the refrigeration cavity in the first flow path 101, it flows along the third conveying pipeline 107 to the disinfection inner container 12, and then flows to the external environment through the exhaust passage.

[0050] It should be added that the cooling of the disinfection inner container 12 should be carried out after the tableware in the disinfection inner container 12 is dried.

[0051] Please refer to Figures 1 to 4 , in an alternative embodiment, the fluid power component 40 is arranged outside the disinfection inner container 12 and the steam cooking inner container 11. The fluid power component 40, the first disinfection cavity and the refrigeration cavity are connected in series and jointly define the first flow path 101. Among them, the fluid power component 40 can be arranged between the first disinfection cavity and the refrigeration cavity, or the refrigeration cavity can be arranged between the fluid power component 40 and the first disinfection cavity. Only examples are given here.

[0052] Furthermore, the disinfection inner container 12 is also provided with a fourth conveying pipeline 108. The other end of the fourth conveying pipeline 108 is connected to the air inlet of the first flow path 101. The fourth conveying pipeline 108 is connected with a third air pipe 106. The third air pipe 106 divides the fourth conveying pipeline 108 into a third section 1081 and a fourth section 1082, and the two are communicated. The third section 1081 is connected to the air inlet of the first flow path 101, and the fourth section 1082 is connected to the disinfection inner container 12. The fourth section 1082 and the third air pipe 106 jointly define the exhaust passage. During actual use, the fourth conveying pipeline 108 is provided with a fourth control valve 64 at the fourth section 1082, and the third air pipe 106 is provided with a fifth control valve 65. In the third state, the first control valve 61 and the fifth control valve 65 are opened, and the fourth control valve 64 is closed. The gas flowing in along the first air pipe 104 flows through the first flow path 101 and is refrigerated, and then flows along the third conveying pipeline 107 to the disinfection inner container 12. The cooled gas flows along the fourth section 1082 to the third air pipe 106 and then is discharged. In this process, precisely because the fourth control valve 64 is closed, the gas flowing through the fourth section 1082 cannot flow to the third section 1081, thus meeting the continuous cooling of the disinfection inner container 12.

[0053] In actual use, the third state and the first state can be carried out simultaneously or alternatively. That is to say, the first cooling circuit and the second cooling circuit can be connected simultaneously or alternatively. When connected simultaneously, the third control valve 63 and the fourth control valve 64 are closed, the first control valve 61, the second control valve 62 and the fifth control valve 65 are opened. After the gas flowing in through the first air pipe 104 flows through the first flow path 101, a part of it flows along the first conveying pipe 102 to the steaming and baking inner container 11, and then flows out through the first section 1031 of the second conveying pipe 103 and the second air pipe 105 to realize the cooling of the steaming and baking inner container 11; moreover, another part flows along the third conveying pipe 107 to the disinfection inner container 12, and then flows out through the fourth section 1082 of the fourth conveying pipe 108 and the third air pipe 106 to realize the cooling of the disinfection inner container 12.

[0054] Furthermore, the steaming, baking and disinfection integrated machine further has a fourth state. In the fourth state, the first flow path 101, the third conveying pipe 107, the disinfection inner container 12 and the fourth conveying pipe 108 are connected and jointly define a second disinfection circuit. At this time, both the lamp tube and the fluid power component 40 are turned on, so that the air entering the first disinfection cavity is excited to generate ozone, which then flows along the third conveying pipe 107 to the disinfection inner container 12 for sterilizing the disinfection inner container 12; moreover, the lamp tube being turned on also continuously releases disinfection light to the disinfection inner container 12, improving the disinfection effect of the disinfection inner container 12.

[0055] Among them, the fourth state and the second state can be carried out simultaneously or alternatively. That is to say, the first disinfection circuit and the second disinfection circuit can be connected simultaneously or alternatively. When connected simultaneously, the first control valve 61, the second control valve 62 and the fifth control valve 65 are closed, the third control valve 63 and the fourth control valve 64 are opened, and the air in the steaming and baking inner container 11 flows along the second conveying pipe 103 to the first flow path 101 under the action of the fluid power component 40 to generate ozone in the first flow path 101, and then flows along the first conveying pipe 102 to the steaming and baking inner container 11 to realize the disinfection cycle of the steaming and baking inner container 11; at the same time, the air in the disinfection inner container 12 flows along the fourth conveying pipe 108 to the first flow path 101 under the action of the fluid power component 40, generates ozone in the first flow path 101, and then flows along the third conveying pipe 107 to the disinfection inner container 12 to realize the disinfection cycle of the disinfection inner container 12.

[0056] Alternatively, when carrying out the disinfection cycle of the steaming and baking inner container 11 and the disinfection inner container 12, the first control valve 61 on the first air pipe 104 can also be opened to absorb gas from the external environment for compensation when the air is insufficient.

[0057] Please refer to Figures 1 to 4, in some specific embodiments, a first three-way pipe 71 is connected to the air outlet of the first flow path 101. One pipe orifice of the first three-way pipe 71 communicates with the first flow path 101, another pipe orifice communicates with the first conveying pipeline 102, and still another pipe orifice communicates with the third conveying pipeline 107. Meanwhile, a four-way pipe 72 is connected to the air inlet of the first flow path 101. The four-way pipe 72 has a first port, a second port, a third port, and a fourth port. The first port is connected to the air inlet of the first flow path 101, the second port is connected to the second conveying pipeline 103, the third port is connected to the first ventilation pipe 104, and the fourth port is connected to the fourth conveying pipeline 108. The second conveying pipeline 103 is connected to a second three-way pipe 73, and the three pipe orifices of the second three-way pipe 73 are respectively connected to the second ventilation pipe 105, the first section 1031, and the second section 1032; moreover, the fourth conveying pipeline 108 is connected to a third three-way pipe 74, and the three pipe orifices of the third three-way pipe 74 are respectively connected to the third ventilation pipe 106, the third section 1081, and the fourth section 1082.

[0058] Furthermore, the first conveying pipeline 102 and the second conveying pipeline 103 are arranged at a distance from each other, and the distance is relatively far to reduce mutual interference. The third conveying pipeline 107 and the fourth conveying pipeline 108 are also arranged at a distance from each other.

[0059] Please refer to Figures 1 to 4 , optionally, the steaming, baking, and disinfection integrated machine further includes a second disinfection structure 22. The second disinfection structure 22 is arranged outside the steaming and baking inner container 11 and the disinfection inner container 12. The second disinfection structure 22 is provided with a second disinfection chamber. The second disinfection chamber, the first disinfection chamber, and the refrigeration chamber are connected in series and jointly define the first flow path 101. The second disinfection structure 22 can be arranged upstream of the first disinfection chamber in the first flow path 101. After the gas entering from the first flow path 101 is disinfected in the second disinfection chamber, it can flow to the first disinfection chamber and the refrigeration chamber. That is to say, the setting of the second disinfection structure 22 can be used to sterilize the gas flowing to the first disinfection chamber. It can be understood that in the first disinfection circuit and the second disinfection circuit, the gases flowing out through the second conveying pipeline 103 and the fourth conveying pipeline 108 are respectively the air in the steaming and baking inner container 11 and the disinfection inner container 12. These airs may carry certain bacteria by themselves. Therefore, the second disinfection structure 22 is used for pre-sterilization, so that the gas returns to a clean state and then flows to the first disinfection chamber to generate ozone, improving the sterilization effect. Of course, in the first cooling circuit and the second cooling circuit, the air in the external environment flowing in from the first ventilation pipe 104 may also carry bacteria. Therefore, the second disinfection structure 22 can also be used for pre-disinfection.

[0060] Among them, the second disinfection structure 22 adopts an alternating magnetic force sterilization chamber. The alternating magnetic force sterilization chamber is a device that uses an alternating magnetic field to sterilize microorganisms in gas. Specifically, the object to be sterilized in the moving gas cuts the alternating magnetic induction lines, and deep sterilization treatment is carried out on the inside of the germs through magnetic force. The alternating magnetic force sterilization chamber can adopt a multi-layer permanent magnet assembly, so that the germs in the air enter a changing magnetic field. Or, a multi-layer electromagnetic coil can also be adopted, and each layer of electromagnetic coil forms a magnetic field, so that the germs in the air enter the changing magnetic field to achieve sterilization. The second disinfection structure 22 can be arranged between the fluid power component 40 and the first disinfection structure 21, or the second disinfection structure 22 is arranged between the fluid power component 40 and the refrigeration structure 30.

[0061] Please refer to Figures 5 to 9 , as some other exemplary embodiments, the side wall of the steaming and baking inner container 11 is provided with a ventilation port, and the fluid power component 40 is arranged at the ventilation port and connected to the air outlet of the first flow path 101. The disinfection inner container 12 is provided with a fifth conveying pipeline 109 and an exhaust passage. The other end of the fifth conveying pipeline 109 is connected to the air inlet of the first flow path 101, and the exhaust passage is used to communicate with the external environment. In this embodiment, when the steaming, baking and disinfection integrated machine is in the third state, the first ventilation pipe 104, the first flow path 101, and the steaming and baking inner container 11 are connected and jointly define a preheating flow path. The preheating flow path is connected to the disinfection inner container 12 through the fifth conveying pipeline 109, and jointly defines a second cooling circuit with the exhaust passage.

[0062] At this time, the fourth port of the four-way pipe 72 at the air inlet of the first flow path 101 is connected to the fifth conveying pipeline 109. At the same time, a fan baffle 122 is arranged at the ventilation port. The fan baffle 122 is provided with a plurality of ventilation holes arranged at intervals, which is beneficial to the flow of air. The fan baffle 122 is used to protect the fluid power component 40 to prevent interference from ingredients, tableware, etc. and affect rotation. The wall of the steaming and baking inner container 11 is provided with a concave cavity for accommodating the fluid power component 40. Among them, the air outlet of the first conveying pipeline 102 can be arranged close to the air inlet of the fluid power component 40.

[0063] That is to say, the hydrodynamic component 40 is communicated with the air outlet of the first flow path 101 through the first conveying pipeline 102. At this time, the air flowing in from the first ventilation pipe 104 flows through the first flow path 101 and then flows along the first conveying pipeline 102 towards the hydrodynamic component 40 under the action of the hydrodynamic component 40. After passing through the steaming and baking inner liner 11, it flows along the second conveying pipeline 103 towards the four-way pipe 72 at the air inlet of the first flow path 101. At this time, the first control valve 61 and the second control valve 62 are opened, and the third control valve 63 is closed. The gas introduced can be pre-cooled by using the preheating loop first, and then the cooled gas is promoted to flow along the fifth conveying pipeline 109 towards the disinfection inner liner 12 for cooling the disinfection inner liner 12. Moreover, due to the setting of the second disinfection structure 22, the gas in the preheating flow path can be sterilized and disinfected.

[0064] Among them, a sixth control valve 66 is provided on the fifth conveying pipeline 109. During actual use, the first control valve 61 and the second control valve 62 can be opened first, and the third control valve 63 and the sixth control valve 66 are closed. After the gas circulates along the preheating flow path for a certain period of time, the first control valve 61 is closed, and the sixth control valve 66 is opened, then the pre-cooled gas can be guided to flow towards the disinfection inner liner 12.

[0065] Furthermore, the exhaust passage is the exhaust hole 121 provided on the disinfection inner liner 12. A check structure is provided at the exhaust hole 121 to enable the air in the disinfection inner liner 12 to be discharged outward, while the external air cannot enter the disinfection inner liner 12 to ensure the cooling efficiency in the disinfection inner liner 12. For example, the check structure can be set as a check valve flap.

[0066] Please refer to Figures 9 to 11 , in this embodiment, the hydrodynamic component 40 is a fan. Specifically, the fan includes a rotating shaft 41 and a fan blade group 42 connected to the rotating shaft 41. The fan blade group 42 includes a base 421 connected to the rotating shaft 41 and blades 422 connected to the base 421. A plurality of blades 422 are provided and arranged at intervals along the circumferential direction of the rotating shaft 41. The rotating shaft 41 is used to connect to the motor, and under the action of the motor, drives a plurality of blades 422 to rotate synchronously through the base 421 to accelerate the air flow. The setting of the base 421 improves the assembly reliability of each blade 422 relative to the rotating shaft 41. Among them, the base 421 and the plurality of blades 422 are integrally formed, for example, by machining. A convex portion is punched at a position near the middle of the base 421 to connect the rotating shaft 41 by using the convex portion, so that the installation position of the base 421 relative to the rotating shaft 41 is closer to the end of the rotating shaft 41, reducing assembly interference.

[0067] Among them, at least part of the blade 422 includes a first spoiler 4221 and a second spoiler 4222, which are connected and arranged at an angle, and the cross section of the first spoiler 4221 along the axial direction of the rotating shaft 41 is gradually expanding from the inside to the outside. It can be understood that, it is precisely because of the arrangement of the first spoiler 4221 and the second spoiler 4222 at an angle that when the blade 422 rotates with the rotating shaft 41, the first spoiler 4221 and the second spoiler 4222 can act on the airflow, thereby generating shear forces in different directions on the airflow, that is, generating spoiler effects in different directions, thereby improving aerodynamic efficiency and facilitating uniform distribution of gas. At the same time, since the cross section of the first spoiler 4221 along the axial direction of the rotating shaft 41 is gradually expanding from the inside to the outside, that is, from the base 421 toward the outer peripheral edge of the blade 422, it is gradually expanding. Such a setting, on the one hand, ensures that the size near the base 421 is small, reducing the connection interference of each blade 422 relative to the base 421; on the other hand, the gradual expansion setting is used to further increase the airflow speed and the uniform distribution of the airflow, thereby improving the aerodynamic efficiency. When the fan is used in the steam-bake inner pot 11, it can promote the uniform distribution of hot air in the steam-bake inner pot 11, ensuring that the cooking effect of uniform doneness is achieved in a shorter cooking time.

[0068] In actual use, each blade 422 may include a first spoiler 4221 and a second spoiler 4222 .

[0069] See also Figures 9 to 11 , exemplarily, the first spoiler 4221 and the second spoiler 4222 are both arranged in a flat plate. The thickness direction of the first spoiler 4221 is along the axial direction of the rotating shaft 41, and the thickness direction of the second spoiler 4222 is arranged at an angle to the thickness direction of the first spoiler 4221, for example, it can be arranged vertically. Such an arrangement not only enhances the spoiler effect, but also optimizes the overall structural stability of the fan. Among them, it is precisely because the first spoiler 4221 is arranged in a flat plate along the radial direction of the rotating shaft 41 to generate a circumferential shear force on the airflow, which can effectively guide the airflow, reduce resistance, and improve the operating efficiency of the fan. At the same time, the second spoiler 4222 is arranged perpendicular to the first spoiler 4221 to generate radial and axial shear forces on the airflow, which further enhances the disturbance of the airflow, so that the airflow can be more evenly distributed during the rotation of the fan blades, and the generation of local vortices is reduced. Thus, when it is applied to the steam-bake inner pot 11, the hot air circulation effect of the steam-bake inner pot 11 can be significantly improved, ensuring that the food is heated evenly.

[0070] Further, the first spoiler part 4221 includes a connecting side 4201 and a spoiler side 4202, which are arranged at intervals in the circumferential direction of the rotating shaft 41. The second spoiler part 4222 is connected to the connecting side 4201. The distance between the spoiler side 4202 and the connecting side 4201 in the circumferential direction of the rotating shaft 41 gradually increases from inside to outside. That is to say, the spoiler side 4202 is inclined relative to the connecting side 4201, so that the cross-section of the first spoiler part 4221 gradually increases from inside to outside. Such a setting, on the one hand, improves the connection reliability at the connection between the second spoiler part 4222 and the first spoiler part 4221, is conducive to processing, and reduces stress concentration; on the other hand, improves the spoiler effect.

[0071] Among them, the spoiler side 4202 includes a tapered section 4202a, a straight section 4202b, and a tapered section 4202c. The three are connected in sequence in the direction from the base 421 towards the outer periphery of the blade 422, and the straight section 4202b is substantially parallel to the connecting side 4201. That is to say, the straight section 4202b is connected between the tapered section 4202a and the tapered section 4202c, and one end of the tapered section 4202a departing from the straight section 4202b is connected to the base 421. Both the tapered section 4202a and the tapered section 4202c are inclined relative to the straight section 4202b, so that the cross-sectional width of the first spoiler part 4221 first tapers, then remains unchanged, and then expands. Such a setting, while ensuring a high connection strength between the blade 422 and the base 421, not only reduces the assembly interference between any two adjacent blades 422, but also ensures sufficient space between any two adjacent blades 422 for air flow and air flow spoiling. Among them, a fillet is provided at the connection between the blade 422 and the base 421 to reduce stress concentration.

[0072] Please refer to Figures 9 to 11 Furthermore, the blade 422 is provided with a reinforcing rib 4224, and the reinforcing rib 4224 extends from the base 421 to the middle or near the middle of the straight section 4202b on the first spoiler part 4221. The reinforcing rib 4224 can be formed by stamping the blade 422 and the base 421. By using the setting of the reinforcing rib 4224, the structural strength of the blade 422 group is improved. The length direction of the reinforcing rib 4224 is the same as the length directions of the straight section 4202b and the connecting side 4201, and the three can be arranged in parallel.

[0073] In some alternative embodiments, the length direction of the connecting side 4201 is arranged at an angle with the radial direction of the rotating shaft 41. Since the connecting side 4201 is connected to the second spoiler part 4222, such a setting is equivalent to the second spoiler part 4222 being arranged at an angle with the radial direction. In this way, different direction components can be generated in the second spoiler part 4222, improving the spoiler effect.

[0074] Please refer to Figures 9 to 11, as some of the exemplary ones, second spoiler parts 4222 are convexly provided on both sides of the first spoiler part 4221 along the axial direction of the rotation axis 41. Such a setting ensures that the airflows on both sides of the first spoiler part 4221 in the thickness direction can spoiler the second spoiler parts 4222, further improving the aerodynamic efficiency. During actual use, the blower has an air inlet side and an air outlet side, and the two are arranged at intervals along the axial direction of the rotation axis 41. The protruding length of the second spoiler part 4222 on the air outlet side is greater than the protruding length of the second spoiler part 4222 on the air inlet side. It can be understood that when the blower is applied to the steam cooking inner container 11, the side with a larger protruding length of the second spoiler part 4222 compared to the first spoiler part 4221 faces the middle of the steam cooking inner container 11.

[0075] Furthermore, arc-shaped notches 4223 are provided at the top corners near the outer periphery of the blade 422 for both the first spoiler part 4221 and the second spoiler part 4222. By using the setting of the arc-shaped notches 4223, the stress concentration at the top corners can be weakened, thereby slowing down the turbulent influence on the airflows, so as to ensure the smooth flow of the airflows on the basis of the largest possible spoiler. In addition, such a setting can improve the structural strength of the blade 422 and reduce the interference with other structures, especially reducing the stress concentration during collision.

[0076] As another exemplary one, the refrigeration structure 30 includes a refrigeration pipeline and a semiconductor component. The refrigeration pipeline forms a refrigeration cavity, and the semiconductor component is configured to form a hot end and a cold end after being powered on, and the refrigeration pipeline is attached to or close to the cold end. In this way, the cold end of the semiconductor component can cool the gas in the refrigeration cavity so as to be transported into the steam cooking inner container 11.

[0077] In a further embodiment, the semiconductor component includes a thermoelectric couple pair, a hot end substrate and a cold end substrate. The thermoelectric couple pair uses semiconductor materials and is arranged between the hot end substrate and the cold end substrate. The hot end substrate is arranged at the hot end, and the cold end substrate is arranged at the cold end. After the refrigeration structure 30 is powered on, electron-hole pairs are generated at one end of the thermoelectric couple pair, resulting in a decrease in internal energy and a decrease in temperature, forming the cold end; while at the other end, due to the recombination of electron-hole pairs, the internal energy increases and the temperature rises, forming the hot end to dissipate heat outward.

[0078] As Figure 1 and Figure 2 shown, in a specific embodiment, the steam cooking and disinfection integrated machine further includes a controller 50. The controller 50 is assembled on the top of the steam cooking inner container 11, and the controller 50 is attached to or close to the refrigeration cavity. In this way, the refrigeration structure 30 can also cool the controller 50, promote the heat dissipation of the controller 50, and ensure the stable operation of the controller 50.

[0079] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0080] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
