[0073] The present invention provides a cooking appliance 100.

[0074] Please refer to Figure 1 , in some embodiments of the present application, the cooking appliance 100 includes:

[0075] An appliance main body 10, in which a cooking space 111 and a water collecting cavity 151 are formed; and

[0076] A condensation module 30, which is arranged in the appliance main body 10, and a condensation channel 34 is formed in the condensation module 30, and the condensation channel 34 communicates the cooking space 111 and the water collecting cavity 151; and

[0077] A heat exchange blower 50, which is arranged in the appliance main body 10 and is used to drive air flow to dissipate heat from the condensation module 30.

[0078] Specifically, the cooking appliance 100 proposed in this application can be, but is not limited to, a rice cooker, a steam box, a steam oven, and other appliances that generate steam during the cooking process. A cooking space 111 for placing and cooking food materials is formed inside the appliance main body 10 of the cooking appliance 100, and a water collection cavity 151 communicated with the cooking space 111 is formed. The water collection cavity 151 is communicated with the cooking space 111 through a condensation channel 34 of a condensation module 30. During cooking, the steam generated by the cooking appliance 100 during the cooking process can flow into the water collection cavity 151 through the condensation channel 34; and the cooking appliance 100 further includes a heat exchange fan 50, and the heat exchange fan 50 can be an axial flow fan or a vortex fan. The setting of the heat exchange fan 50 can drive the air flow and blow it towards the condensation module 30. During the process of the air flow flowing through the condensation channel 34, the cold air driven by the heat exchange fan 50 exchanges heat with the condensation module 30 and takes away the heat and dissipates it to the external environment, so as to improve the heat dissipation efficiency of the condensation module 30, enable the steam flowing through the condensation module 30 to be better cooled and condensed, enable the cooking appliance 100 to better achieve the effect of no steam or micro-steam emission, and the cooled water and uncondensed steam formed after condensation will be discharged into the water collection cavity 151.

[0079] In some embodiments, the cold air driven by the heat exchange fan 50 can also dissipate heat from the water collection cavity 151; with such a setting, when the steam generated in the cooking space 111 enters the water collection cavity 151, the steam can also exchange heat with the cavity wall of the water collection cavity 151, and the cold air driven by the heat exchange fan 50 takes away the heat of the water collection cavity 151, so that the temperature of the steam drops and can be condensed into water and stored in the water collection cavity 151. This can also further reduce or avoid the discharge of steam to the outside of the cooking appliance 100, achieve the purpose of micro-steam or no-steam emission during the cooking process, and thus avoid the influence of steam on the surrounding environment and avoid scalding users with steam.

[0080] Among them, the condensation module 30 can be made of materials with good thermal conductivity and heat dissipation performance, such as aluminum, aluminum alloy, copper or copper alloy, etc., so that during the process of the steam flowing in the condensation module 30, the heat can be better dissipated through the condensation module 30 to improve the condensation effect. Similarly, in some embodiments, at least part of the structure of the water collection box 15 forming the water collection cavity 151 can also be made of materials with good thermal conductivity and heat dissipation performance, which will not be elaborated here.

[0081] In some embodiments, a channel for guiding the cold air blown by the heat exchange fan 50 may be provided in the cooking appliance 100, and the condensation module 30 may be disposed in this channel. For the heat exchange fan 50, the calculation method of its power can be calculated by the energy of the driven air flow, that is, fan power = fan flow * wind pressure / 1000 / 3600 * fan efficiency (kw), where the fan flow = cross-sectional area of the channel * wind speed; in addition, the power of the heat exchange fan 50 can also be calculated from the operating current and operating voltage, that is, fan power = operating current * operating voltage * fan efficiency (kw). That is, under the condition that the operating voltage, wind speed and wind pressure of the heat exchange fan 50 are constant, the operating current of the heat exchange fan 50 is positively correlated with the cross-sectional area of the channel for the cold air to flow. In the embodiments of the present application, it is possible to determine whether the condensation module 30 is installed in the cooking appliance 100 by detecting the operating current of the heat exchange fan 50 during operation; it can be understood that when the condensation module 30 is installed in the cooking appliance 100, due to the obstruction of the condensation module 30, the cross-sectional area of the channel for the cold air to flow becomes smaller, and at this time the operating current of the heat exchange fan 50 is also smaller; when the condensation module 30 is not installed in the cooking appliance 100, the cross-sectional area of the channel for the cold air to flow is larger, and at this time the operating current of the heat exchange fan 50 increases. Set the operating current value of the heat exchange fan 50 when the condensation module 30 is installed as the preset current value. If it is detected that the operating current of the heat exchange fan 50 during operation is greater than the preset current value, it is confirmed that the condensation module 30 is not installed in the cooking appliance 100. At this time, the cooking program can be stopped; alternatively, an instruction to install the condensation module 30 can be issued by the cooking appliance 100. The instruction can be an indication signal, such as a buzzer, an indicator light, or a message sent to the terminal, etc., to prompt the user to install the condensation module 30. If after a preset time period after the instruction is issued, when the heat exchange fan 50 is running, it is detected that the operating current of the heat exchange fan 50 does not exceed the preset current value, it is confirmed that the condensation module 30 has been installed. At this time, the normal cooking program can be run; if the detected operating current is still greater than the preset current value, the cooking program can be directly stopped, or operations such as repeating the instruction to install the condensation module 30 can be performed until the preset number of times or until it is confirmed that the condensation module 30 has been installed.

[0082] In addition, the start / stop of the heating device, input current, input power, heating power adjustment ratio, heating time, etc. during the cooking process, or parameters such as the temperature or steam generation amount in the cooking space 111 can be detected to control the start / stop and rotation speed of the heat exchange fan 50. For example, the heat exchange fan 50 is started synchronously when the heating device is turned on, or the fan is started when steam is generated in the cooking space 111; in some embodiments, the heating device performs cooking in a periodic intermittent heating manner at least during the boiling stage. During this process, the rotation speed of the heat exchange fan 50 can be controlled according to the heating power adjustment ratio of each heating cycle; it can be understood that the steam generation amount is related to the heating power adjustment ratio of the cooking appliance 100. The higher the heating power adjustment ratio, the more steam is generated, and the more steam enters the condensation module 30. It is necessary to make the condensation module 30 have a higher heat dissipation efficiency to ensure that the steam can be effectively cooled and condensed; when the heating power adjustment ratio is small, the steam generation amount is low, and the steam can also be cooled and condensed under the condition of appropriately reducing the heat dissipation efficiency. When the heating power adjustment ratio increases, the rotation speed of the heat exchange fan 50 is correspondingly increased, so that the heat conduction pipe can dissipate heat faster, improving the heat dissipation efficiency of the heat conduction pipe, to ensure that the steam entering the condensation module 30 can be effectively cooled and condensed, and to ensure that the purpose of no steam or micro-steam release can be achieved under the condition of a high heating power adjustment ratio. When the heating power adjustment ratio decreases, the rotation speed of the heat exchange fan 50 is correspondingly reduced. Under the condition of ensuring the steam cooling and condensation effect, the heat exchange fan 50 does not need to run at full speed, which not only achieves the purpose of no steam or micro-steam emission, but also reduces the noise and energy consumption during the operation of the cooking appliance 100.

[0083] Of course, the input current and input power of the heating device, etc. will also affect the steam generation amount. Therefore, the rotation speed of the heat exchange fan 50 can also be adjusted by detecting the input current or input power of the heating device, etc., or directly detecting the steam generation amount in the cooking space 111. Similarly, while ensuring no steam or micro-steam emission, the noise and energy consumption during the operation of the cooking appliance 100 are reduced.

[0084] Therefore, it can be understood that in the technical solution of the present application, by providing a condensation module 30 and a heat exchange fan 50 in the cooking appliance 100, the steam generated in the cooking space 111 during the cooking process can flow through the condensation channel 34 of the condensation module 30 to the water collection chamber 151; during the flow of the steam along the condensation channel 34, the heat exchange fan 50 can drive cold air to exchange heat with the condensation module 30, so as to take away the heat transferred from the steam to the condensation module 30, thereby achieving the purpose of cooling the steam, so that most of the steam is condensed into water after cooling and flows into the water collection chamber 151; the setting of the heat exchange fan 50 can improve the heat dissipation efficiency of the condensation module 30, accelerate the steam heat dissipation, improve the steam condensation efficiency, and make more steam condensed into water. That is, through the setting of the condensation module 30 and the heat exchange fan 50, the present application can reduce or avoid the outward discharge of steam, so as to achieve the purpose of micro-steam or steam-free discharge during the cooking process.

[0085] Please refer to Figure 1 , in some embodiments of the present application, the condensation channel 34 extends in a zigzag manner.

[0086] In this embodiment, the condensation channel 34 extends in a zigzag manner, which can be set as an arc, or a spiral winding structure, a reciprocating bending and winding structure or other winding methods; such a setting can extend the length of the condensation channel 34, extend the steam flow path and flow time, thereby extending the heat exchange time between the steam and the condensation module 30, enabling better cooling of the steam and improving the condensation effect. The formation of the condensation channel 34 can be achieved by setting a diversion pipe 31 in the following embodiments, or by setting a diversion groove 351 in the condensation seat body 35 and other methods.

[0087] Please refer to Figure 1 , in some embodiments of the application, the condensation module 30 includes a diversion pipe 31, one end of the diversion pipe 31 is communicated with the cooking space 111, and the other end of the diversion pipe 31 is communicated with the water collection chamber 151.

[0088] In this embodiment, the condensation module 30 includes a diversion pipe 31, and the diversion pipe 31 can be an aluminum pipe, an aluminum alloy pipe, a copper pipe, a copper alloy pipe or a stainless steel pipe with good heat dissipation performance, etc.; the condensation channel 34 is formed by adopting a tubular structure, which is convenient for shaping the condensation channel 34, and the wall thickness of the tubular structure is relatively thin, which can improve the heat dissipation efficiency of the steam.

[0089] Please refer to Figure 1 , in some embodiments of the present application, the condensation module 30 includes heat dissipation fins 33, and the heat dissipation fins 33 are in contact with the diversion pipe 31.

[0090] In an embodiment of the present application, the condensation module 30 includes heat dissipation fins 33 and brings the heat dissipation fins 33 into contact with the diversion pipe 31; with such a setting, the heat of the heat conduction pipe and the steam can be transferred to the heat dissipation fins 33, and the heat dissipation area of the diversion pipe 31 is increased through the heat dissipation fins 33, so that the heat of the diversion pipe 31 and the steam can be quickly dissipated outward, improving the heat dissipation efficiency and enabling the steam to be quickly cooled and condensed. Among them, the diversion pipe 31 can be arranged on the surface of the heat dissipation fins 33 or, as in the following embodiment, penetrate through the heat dissipation fins 33, which is not limited herein.

[0091] The heat exchange fan 50 can drive the air flow to dissipate heat from the diversion pipe 31 and the heat dissipation fins 33 to improve the condensation efficiency. When the heat dissipation fins 33 can improve the heat dissipation efficiency of the diversion pipe 31, the rotation speed of the heat exchange fan 50 can be appropriately reduced, which can not only improve the heat dissipation efficiency to ensure the condensation of the steam, but also reduce the noise generated during the operation of the heat exchange fan 50.

[0092] Please refer to Figure 1 , in some embodiments of the present application, the diversion pipe 31 penetrates through the heat dissipation fins 33.

[0093] In this embodiment, the heat dissipation fins 33 can be set to have a certain thickness, at least part of the diversion pipe 31 can be embedded in the heat dissipation fins 33, or a channel for the steam to flow can be directly formed in the heat dissipation fins 33, that is, the heat dissipation fins 33 and the diversion pipe 31 are integrally formed; it can also be a plurality of heat dissipation fins 33 arranged side by side, so that the diversion pipe 31 penetrates through each heat dissipation fin 33 from the surface of the heat dissipation fins 33. With such a setting, not only can the connection strength between the heat dissipation fins 33 and the diversion pipe 31 be improved, avoiding the separation of the diversion pipe 31 and the heat dissipation fins 33 and making it difficult for the heat of the diversion pipe 31 to be transferred to the heat dissipation fins 33; in addition, compared with the way of arranging the diversion pipe 31 on the surface of the heat dissipation fins 33, the contact area between the diversion pipe 31 and the heat dissipation fins 33 is also increased, improving the heat conduction efficiency and enabling the heat of the diversion pipe 31 and the steam to be quickly transferred to the heat dissipation fins 33 for heat dissipation.

The baffle 353 extends along the second direction and is spaced between the channel inlet and the channel outlet along the first direction, such that one end of the baffle 353 is connected to one of the two side walls spaced along the second direction, and the other end of the baffle 353 is spaced from the other side wall to form a conduction port 355. Moreover, the channel inlet and the adjacent conduction port 355 are arranged in a dislocation along the length direction of the baffle 353, and the channel outlet and the adjacent conduction port 355 are arranged in a dislocation along the length direction of the baffle 353. With such an arrangement, when the steam enters the condensation channel 34 from the channel inlet, it will be blocked by the adjacent baffle 353 and cannot directly flow to the channel outlet, and needs to flow along the length direction of the baffle 353 to the conduction port 355 to flow through the baffle 353 to the channel outlet; thereby extending the length of the condensation channel 34 in the condensation module 30, extending the steam flow path and flow time, thereby extending the heat exchange time between the steam and the condensation module 30, enabling the steam to cool better and improving the condensation effect.

[0102] Please refer to Figure 12 and Figure 13 , in an embodiment of the present application, at least two of the baffles 353 are provided in the condensation base 35. Among the adjacent two baffles 353, one baffle 353 is connected to one side wall, and the other baffle 353 is connected to the other side wall, and the two formed conduction ports 355 are located on two sides away from each other.

[0103] In this embodiment, at least two baffles 353 are provided in the condensation base 35, and one of the adjacent two baffles 353 is connected to one of the two side walls spaced along the second direction in the flow space, and the other baffle 353 is connected to the other side wall, so that the conduction ports 355 at the ends of the adjacent two baffles 353 are arranged in a dislocation along the length direction of the baffle 353, so that after the steam passes through one baffle 353, it must flow along the area between the two baffles 353 to the conduction port 355 at the other end, extending the steam flow path and flow time, thereby extending the heat exchange time between the steam and the condensation module 30, enabling the steam to cool better and improving the condensation effect.

[0104] Please refer to Figure 14, in an embodiment of the present application, the condensation module 30 further includes at least one heat sink 354, and the heat sink 354 is disposed on the surface of the condensation base 35 facing away from the condensation cover 37.

[0105] In this embodiment, at least one heat sink 354 is attached to the bottom wall of the condensation base 35. The heat sink 354 can be made of materials with good heat conduction and heat dissipation performance such as aluminum, aluminum alloy, copper, or copper alloy. The heat sink 354 can be fixed to the bottom wall of the condensation base 35 by means of pasting, bolt locking, clamping, etc., or the condensation base 35 and the heat sink can be integrally formed of the same material. The setting of the heat sink 354 can improve the heat dissipation and cooling efficiency of the condensation base 35, thereby improving the steam cooling and condensation efficiency.

[0106] Please refer to Figures 10 to 12 , in an embodiment of the present application, a support wall 357 protrudes from the surface of the condensation base 35 facing away from the condensation cover 37. The support wall 357 is arranged to surround the condensation base 35 in the circumferential direction to enclose a heat dissipation space 358, and a ventilation opening 359 communicating with the heat dissipation space 358 is formed in the support wall 357.

[0107] In this embodiment, a heat dissipation space 358 is enclosed by the support wall 357 on one side of the bottom wall of the condensation base 35, and a ventilation opening communicating with the heat dissipation space 358 is formed in the support wall 357. With such a setting, when the condensation module 30 is installed on the installation surface provided on the appliance main body through the condensation base 35, the support wall 357 abuts against the installation surface, thereby preventing the bottom wall of the condensation base 35 from directly contacting the installation surface. At this time, the condensation base 35 can dissipate heat through the heat dissipation space 358 and the ventilation opening between the bottom wall and the installation surface, improving the heat dissipation efficiency of the condensation module 30 and the steam cooling and condensation efficiency.

[0108] Please refer to Figure 10 and Figure 11 , in an embodiment of the present application, a limiting step 356 is formed on the inner side wall of the condensation base 35. The limiting step 356 is arranged to surround the condensation base 35 in the circumferential direction, and the condensation cover 37 is supported on the limiting step 356.

[0109] In this embodiment, a limiting step 356 is formed on the inner side wall of the condensation base 35. The step surface of the limiting step 356 faces the condensation cover 37 and is arranged to surround the condensation base 35 in the circumferential direction. The condensation cover 37 can be supported on the limiting step 356, so that the condensation cover 37 is limited and installed inside the condensation base 35, improving the connection strength between the condensation cover 37 and the condensation base 35 and the overall structural stability of the condensation module 30.

[0110] In addition, in the following embodiments, a sealing sleeve housing is wrapped around the condensation cover body 37. Thus, when the condensation cover body 37 is closed on the condensation base body 35, a partial structure of the sealing sleeve housing is clamped between the limiting step 356 and the condensation cover body 37, and is also clamped between the side wall of the condensation cover body 37 and the inner side wall of the condensation base body 35, improving the sealing performance of the connection position between the condensation base body 35 and the condensation base body 35.

[0111] Please refer to Figures 10 to 12 , in an embodiment of the present application, the condensation module 30 further includes a sealing member 39, the sealing member 39 is arranged to surround the circumference of the condensation base body 35, and at least part of the sealing member 39 is clamped between the condensation base body 35 and the condensation cover body 37.

[0112] In this embodiment, a sealing member 39 is arranged between the condensation cover body 37 and the condensation base body 35. The sealing member 39 can be structures such as a sealing ring and a sealing sleeve housing. The sealing member 39 has a certain elasticity. Thus, when clamped by the condensation cover body 37 and the condensation base body 35, it can generate elastic deformation to fit the condensation cover body 37 and the condensation base body 35, improving the sealing performance of the connection position between the condensation base body 35 and the condensation base body 35, and preventing steam from leaking out from the connection position between the condensation cover body 37 and the condensation base body 35.

[0113] Please refer to Figures 10 to 12 , in an embodiment of the present application, the sealing member 39 is a sealing sleeve housing, a wrapping cavity 391 is formed inside the sealing sleeve housing, and the sealing cover body is arranged in the wrapping cavity 391.

[0114] In this embodiment, the sealing member 39 is arranged as a sealing sleeve housing, and the condensation cover body 37 is wrapped in the wrapping cavity 391 of the sealing sleeve housing, which can stably connect the condensation cover body 37 and the sealing sleeve housing, and improve the assembly convenience of the condensation module 30. It only needs to close the combined structure of the condensation cover body 37 and the sealing sleeve housing on the condensation base body 35; and through the constraint of the condensation cover body 37 on the sealing sleeve housing, the sealing member 39 can be prevented from being displaced, ensuring that the connection position between the condensation base body 35 and the condensation base body 35 maintains good sealing performance. It should be noted that the sealing sleeve housing can cover all surfaces of the condensation cover body 37, or only cover the partial surface of the condensation cover body 37 in contact with the condensation base body 35. For example, in order to facilitate the installation of the condensation cover body 37 into the sealing sleeve housing, an opening can be provided on the surface of the sealing sleeve housing facing away from or towards the condensation base body 35, so that the condensation cover body 37 can enter and exit the wrapping cavity 391 from the opening.

[0115] Please refer to Figure 9 and Figure 12, in an embodiment of the present application, an insertion port 393 is formed in a part of the sealing sleeve shell located on the side of the condensation cover body 37 facing away from the condensation base body 35. A plug post 371 protrudes from the surface of the sealing cover body facing away from the condensation base body 35, and the plug post 371 is inserted into the insertion port 393.

[0116] In this embodiment, a plug post 371 protrudes from the surface of the condensation cover body 37 facing away from the condensation base body 35, and an insertion port 393 is formed in the sealing sleeve shell, so that the plug post 371 is inserted into the insertion port 393. Such a setting not only facilitates the positioning and installation between the condensation cover body 37 and the sealing sleeve shell, but also improves the connection strength between the condensation cover body 37 and the sealing sleeve shell, and avoids problems such as the deviation of the sealing sleeve shell.

[0117] Please refer to Figures 2 to 6 , in some embodiments of the present application, the cooking appliance 100 further includes a mounting base 70. The mounting base 70 is disposed on the appliance main body 10. An installation cavity 71 is formed in the mounting base 70. An air passing port 75 communicating with the installation cavity 71 is formed in the side wall of the mounting base 70. The heat exchange fan 50 is disposed in the installation cavity 71;

[0118] The top surface of the mounting base 70 forms a mounting surface, and an air outlet 73 communicating with the installation cavity 71 is formed. The condensation module 30 is disposed on the mounting surface, and the air outlet 73 is arranged facing the condensation module 30.

[0119] In this embodiment, the cooking appliance 100 further includes a mounting base 70. An installation cavity 71 is formed in the mounting base 70. The heat exchange fan 50 is arranged in the installation cavity 71, which can prevent the heat exchange fan 50 from contacting steam, and improve the service life and reliability of the heat exchange fan 50. An air passing port 75 communicating with the installation cavity 71 is formed in the side wall of the mounting base 70, and an air outlet 73 communicating with the installation cavity 71 is formed on the mounting surface at the top of the mounting base 70; so that the heat exchange fan 50 can drive the external air flow to enter the installation cavity 71 from the air passing port 75, and then flow out from the air outlet 73 and blow towards the condensation module 30, thereby using the air flow to dissipate heat from the condensation module 30. The setting of the mounting base 70 can protect the heat exchange fan 50 and also play a role in guiding the air flow, so that the air flow blows accurately towards the condensation module 30, improving the heat dissipation effect of the condensation module 30. And the distance between the heat exchange fan 50 and the condensation module 30 is only the thickness of the top wall of the mounting base 70, shortening the distance between the heat exchange fan 50 and the condensation module 30, which can improve the heat dissipation effect on the condensation module 30.

[0120] In some embodiments, the condensation module 30 is detachably connected to the mounting surface. With this arrangement, the condensation module 30 can be separately removed from the cooking appliance 100 for cleaning, maintenance or replacement, improving the convenience of use. This can not only make the condensation module 30 washable, but also maintain the stability of the installation and electrical connection of the heat exchange fan 50.

[0121] In addition, in the embodiments of the present application, the mounting base 70 can be set as a box structure, and the mounting base 70 is detachably connected to the appliance main body 10, that is, the installation cavity 71 is formed by the mounting base 70 itself. The heat exchange fan 50 and the mounting base 70 form an integral structure, and the heat exchange fan 50 can be installed in the mounting base 70 and installed on or removed from the appliance main body 10 together with the mounting base 70; alternatively, the mounting base 70 and the appliance main body 10 can enclose to form the installation cavity 71. For example, in some embodiments, the mounting base 70 is arranged on the cover 13 of the appliance main body 10. The mounting base 70 can be set as a structure with an open bottom and covered on the cover 13, so that the surface of the cover 13 serves as the bottom wall of the installation cavity 71, and thus the heat exchange fan 50 can be fixed on the surface of the cover 13. At this time, removing the mounting base 70 from the cover 13 can expose the heat exchange fan 50.

[0122] Please refer to Figures 1 to 3 , in some embodiments of the present application, the cooking appliance 100 further includes a cover 90. The cover 90 covers the mounting surface and encloses an accommodation space 91 with the mounting base 70. The cover 90 is provided with a ventilation opening 93 communicating with the accommodation space 91, and at least part of the condensation module 30 is arranged in the accommodation space 91.

[0123] In this embodiment, the cooking appliance 100 further includes a cover 90. The cover 90 can be a cover structure, including a top wall and a surrounding edge 77 disposed around the top wall. An installation space 91 is formed between the top wall and the surrounding edge 77. When the cover 90 covers the installation surface at the top of the mounting base 70 to enclose the installation space 91, the surrounding edge 77 abuts against the mounting base 70, and at least part of the condensation module 30 is located in the installation space 91. The cover 90 can also be a cover plate structure. In this case, a surrounding edge 77 disposed in a surrounding manner needs to be protruded on the installation surface, and at least part of the condensation module 30 is disposed in the installation space 91 enclosed by the surrounding edge 77. When the cover 90 covers the mounting base 70, it abuts against the surrounding edge 77 protruded on the installation surface, thereby enclosing the installation space 91. With such a setting, it can protect the condensation module 30 located in the installation space, and make the airflow driven by the heat exchange fan 50 concentrate on blowing towards the condensation module 30 to dissipate heat from the condensation module 30, preventing the airflow from escaping around from the air outlet 73. In addition, a ventilation opening 93 communicating with the installation space is opened on the cover 90. The ventilation opening 93 can be circular, rectangular, square, polygonal, or other regular or irregular shapes. The setting of the ventilation opening 93 enables the airflow entering the installation space to be discharged outward from the ventilation opening 93 to take away heat, preventing the unsmooth discharge of the airflow from affecting the heat dissipation efficiency. Among them, a grille structure can be provided on the cover 90, or a plurality of ventilation openings 93 can be opened on the cover 90, which is not limited herein.

[0124] In addition, it should be noted that, in some embodiments, the outlet of the steam channel 131 communicating with the cooking space 111 can be disposed outside the installation space. At this time, the inlet end of the condensation module 30 needs to penetrate out of the installation space to communicate with the outlet of the steam channel 131. Similarly, when the water collection cavity 151 is located outside the installation space, the outlet end of the condensation module 30 needs to penetrate out of the installation space. In some embodiments, a steam joint 133 can be provided at the outlet of the steam channel 131, and the steam joint 133 is inserted into the installation space. At this time, the outlet end of the condensation module 30 can be located in the installation space. Similarly, the inlet 153 of the water collection cavity 151 can be provided in the installation space, or the water collection cavity 151 can be disposed in the installation space, so that the outlet end of the condensation module 30 can be disposed in the installation space.

[0125] Please refer to Figure 7 and Figure 8 , in some embodiments of the present application, the condensation module 30 includes two connecting joints respectively connected to the inlet end and the outlet end of the condensation channel 34. Both of the two connecting joints extend outside the installation space 91 and are respectively communicated with the cooking space 111 and the water collection cavity 151.

[0126] In this embodiment, the cover 90 can be set as a cover structure, that is, the cover 90 includes a top wall and a surrounding edge 77 arranged around the top wall. An installation space 91 is formed between the top wall and the surrounding edge 77. When the cover 90 covers the installation surface at the top of the mounting base 70, the surrounding edge 77 abuts against the mounting base 70 to form an installation space 91 between the cover 90 and the installation surface. Or the cover 90 can be set as a cover plate structure, with a surrounding edge 77 protruding and arranged around on the installation surface. When the cover 90 covers the mounting base 70, it abuts against the surrounding edge 77 protruding from the installation surface, thereby closing the installation space 91. Additionally, in some embodiments, it can also be that surrounding edges 77 are provided on both the cover 90 and the installation surface, and it can be that the surrounding edge 77 of the cover 90 abuts against the surrounding edge 77 on the mounting base 70, or the surrounding edge 77 of the cover 90 surrounds the outside of the surrounding edge 77 of the mounting base 70, or the surrounding edge 77 of the cover 90 is inserted into the space formed by the surrounding edge 77 of the mounting base 70. Among them, part of the condensation module 30 is arranged in the installation space 91 formed by the surrounding edge 77, and both communication joints provided at the inlet end and the outlet end of the condensation channel 34 in the condensation module 30 pass through the surrounding edge 77 and extend to the outside of the installation space 91, respectively for communicating with the cooking space 111 and the water collection chamber 151.

[0127] In some embodiments, a limiting opening 79 can be formed on the surrounding edge 77 to embed the communication joint in the limiting opening 79. When surrounding edges 77 are provided on both the cover 90 and the installation surface, the limiting opening 79 can be provided only on the surrounding edge 77 of the cover 90 or the mounting base 70, or the limiting opening 79 can be provided on both the surrounding edge 77 of the cover 90 and the surrounding edge 77 of the mounting base 70, and the limiting opening 79 of the cover 90 and the limiting opening 79 of the mounting base 70 are arranged opposite to each other.

[0128] Please refer to Figure 6 , in some embodiments of the present application, the heat exchange fan 50 is a vortex fan, the air inlet of the vortex fan faces the air passing port 75, and the air outlet 51 of the vortex fan faces the air outlet 73.

[0129] In the embodiment of the present application, the side of the mounting base 70 connected to the appliance main body 10 is defined as the bottom of the mounting base 70, and the side opposite to the bottom is defined as the top of the mounting base 70, and it has side walls connecting the top surface and the bottom surface of the mounting base 70. The diversion pipe 31 is arranged at the air outlet 73 on the top surface of the mounting base 70, and the air passing port 75 communicating with the mounting cavity 71 is opened on the side wall of the mounting base 70. At this time, the air passing port 75 and the air outlet 73 are not on the same axis. In this embodiment, the heat exchange fan 50 is set as a vortex fan. The air inlet of the vortex fan is arranged on the circumferential side wall of the volute, and the air outlet 51 of the vortex fan is arranged on the axis of the volute. At this time, the air inlet of the vortex fan can be arranged opposite to the air passing port 75 of the mounting base 70, and the air outlet 51 of the vortex fan can be arranged opposite to the air outlet 73 of the mounting base 70, so that the air flow can smoothly enter the vortex fan from the air passing port 75 through the air inlet, and then be blown from the air outlet 51 to the air outlet 73 under the guidance of the vortex fan; the flow path of the air flow is optimized, so that the air flow is better driven and blown towards the condensation module 30, avoiding problems such as the air flow entering the mounting cavity 71 and turning and fluctuating multiple times, which is likely to form turbulent flow or cause relatively large noise.

[0130] In an embodiment of the present application, the condensation module 30 is detachably connected to the appliance main body 10.

[0131] In this embodiment, the condensation module 30 is detachably connected to the appliance main body 10. With this setting, the condensation module 30 can be separately removed for cleaning, maintenance or replacement, without removing the entire condensation module 30, improving the use convenience. It can not only make the condensation module 30 washable, but also maintain the installation stability of the heat exchange fan 50 and the stability of the electrical connection. The condensation module 30 can be detachably connected to the appliance main body 10 only at both ends of the condensation channel 34 to communicate the cooking space 111 and the water collection cavity 151, for example, by means of plugging or screwing; or straps, limiting grooves and other means can be set to make the condensation module 30 detachably connected to other structures of the appliance main body 10.

[0132] Please refer to Figure 1 , in some embodiments of the present application, the appliance main body 10 includes:

[0133] A pot body 11, within which the cooking space 111 is formed;

[0134] A cover body 13, which is movably covered on the pot body 11; and

[0135] A water collection box 15, which is arranged on the cover body 13 or the pot body 11 and forms the water collection cavity 151;

[0136] The condensation module 30 is provided on the pot body 11 or the lid body 13, and the heat exchange blower 5050 is provided on the pot body 11 or the lid body 13.

[0137] In this embodiment, the appliance main body 10 includes a pot body 11, a water collection box 15, and a lid body 13. A cooking space 111 is formed inside the pot body 11. The pot body 11 can include a housing and an inner pot, and the inner pot forms the cooking space 111. The heating structure can be arranged between the housing and the inner pot. The lid body 13 is coverably arranged on the pot body 11 to close and open the cooking space 111. Additionally, a steam channel 131 can be provided on the lid body 13, and a steam inlet 153 is provided in the area of the lid body 13 facing the pot body 11, so that the cooking space 111 can be connected through the steam channel 131, enabling the steam generated in the cooking space 111 to be discharged through the steam channel 131 and facilitating the connection between the condensation module 30 and the cooking space 111. A water collection cavity 151 is formed inside the water collection box 15, and an air inlet can be opened at the top of the water collection box 15 for connection with the condensation channel 34 of the condensation module 30. Among them, the water collection box 15 can be arranged on the lid body 13 or on the pot body 11. The water collection box 15 is detachably connected to the lid body 13 or the pot body 11, facilitating the removal of the water collection box 15 for cleaning, thereby improving the convenience of use.

[0138] In addition, the condensation module 30 can be arranged on the lid body 13 or on the pot body 11, and the heat exchange blower 5050 can also be arranged on the lid body 13 or on the pot body 11.

[0139] Please refer to Figure 1 , in some embodiments of the present application, the condensation module 30 and the heat exchange blower 5060 are both arranged on the lid body 13, and the lid body 13 forms a steam channel 131 that can communicate with the cooking space 111, and one end of the condensation channel 34 is connected to the steam channel 131.

[0140] In this embodiment, the condensation module 30 is arranged on the lid body 13, and a steam channel 131 is arranged inside the lid body 13. A steam inlet 153 is provided in the area of the lid body 13 facing the pot body 11, and the condensation channel 34 is connected to the steam outlet of the steam channel 131. When the lid body 13 is covered on the pot body 11, the steam inlet 153 communicates with the cooking space 111, so that the steam generated in the cooking space 111 can flow to the condensation channel 34 via the steam inlet 153 and the steam channel 131. Moreover, the steam naturally rises into the steam channel 131 and the condensation channel 34, which can improve the steam discharge efficiency. Additionally, the condensation module 30 is detachably connected to the lid body 13. When the condensation module 30 is removed, the steam can still be discharged outward via the steam channel 131, which is the same as the usage mode of a general cooking appliance 100, improving the usage flexibility of the cooking appliance 100.

[0141] In some embodiments, a steam joint 133 may be provided at the steam outlet of the steam passage 131 to facilitate the connection between the steam passage 131 and the condensation module 30.

[0142] Please refer to Figure 1 , in some embodiments of the present application, the water collection box 15 is provided on the cover body 13. With this arrangement, not only the utilization of the space of the cover body 13 in the appliance main body 10 is improved, but also the volume of the pot body 11 is prevented from being too large. Moreover, it is beneficial to keep the water collection box 15 away from the cooking space 111 to avoid the influence of the heat in the cooking space 111 on the condensation of the steam in the water collection box 15; and it is also convenient for the disassembly and assembly of the water collection box 15.

[0143] Please refer to Figure 1 and Figure 5 , in some embodiments of the present application, the cover body 13 is provided with a fixing groove 135, and at least a part of the water collection box 15 is arranged in the fixing groove 135. With this arrangement, the limiting installation of the water collection box 15 can be realized by using the fixing groove 135, the connection strength between the water collection box 15 and the cover body 13 can be improved, and the installation stability of the water collection box 15 can be enhanced. Wherein, the cover body 13 has a certain thickness. It is defined that the cover body 13 has two opposite surfaces and a side wall located between the two surfaces. When the cover body 13 is closed on the pot body 11, one of the surfaces is arranged opposite to the pot body 11, and the other surface faces away from the pot body 11; the fixing groove 135 can be arranged on the surface of the cover body 13 facing away from the pot body 11; or the fixing groove 135 can be opened on the side wall of the cover body 13, which is not limited herein.

[0144] Please refer to Figure 1 , in some embodiments of the present application, the water collection box 15 is arranged on the side of the cover body 13 facing away from the pot body 11. With this arrangement, the water collection box 15 is made as far away from the cooking space 111 as possible, and the cover body 13 can also play a certain heat insulation role to avoid or reduce the transfer of the heat in the cooking space 111 to the water collection box 15 during the cooking process, thereby avoiding affecting the condensation effect of the steam in the water collection box 15. In addition, it is also convenient to remove the water collection box 15 from the appliance main body 10 to clean the condensed water in the water collection box 15. In some embodiments, a fixing groove 135 may be provided on the surface of the cover body 13 facing away from the pot body 11, and the water collection box 15 may be arranged in the fixing groove 135 to limit the installation of the water collection box 15.

[0145] Please refer to Figure 1 and Figure 4 , in some embodiments of the present application, the appliance main body 10 is provided with an exhaust port 155 communicating with the water collection cavity 151.

[0146] It can be understood that the embodiments of the present application can achieve no steam or micro-steam emission during the cooking process; that is, when the condensation module 30 has a good condensation effect on steam and a high condensation efficiency so that all steam is completely condensed into water and stored in the water collection cavity 151, the cooking appliance 100 achieves the effect of no steam emission. When the steam generation amount is too high, there may be some steam that is not condensed; and if the water collection cavity 151 is closed, causing steam to continuously enter the water collection cavity 151 and unable to be discharged, it is easy to have problems such as a high pressure in the water collection cavity 151 or steam backflow; and if the water collection cavity 151 is opened when there is steam in the water collection box 15, it is easy to cause the steam in the water collection cavity 151 to scald the user. By providing an exhaust hole communicating with the water collection cavity 151, the uncondensed steam can be discharged from the exhaust hole, avoiding the accumulation of steam in the water collection cavity 151 and scalding the user when the water collection cavity 151 is opened.

[0147] Please refer to Figure 4 , in some embodiments of the present application, a flow disturbance structure 157 is provided in the water collection cavity 151, and the flow disturbance structure 157 divides the water collection cavity 151 into a diversion channel 1575 that extends tortuously from the inlet 153 of the water collection cavity 151 to the exhaust port 155.

[0148] In this embodiment, a flow disturbance structure 157 is provided in the water collection cavity 151. The flow disturbance structure 157 can be, for example, setting at least two flow disturbance walls in the water collection cavity 151 to divide a diversion channel 1575 in the water collection cavity 151 in the following embodiments, or setting a continuous flow disturbance wall, such as a spiral flow disturbance wall, to form a spiral diversion channel 1575, so as to disturb and divert the steam entering the water collection cavity 151. It can not only extend the flow path and flow channel time of the steam in the water collection cavity 151, making the steam flow along the tortuous diversion channel 1575 in the water collection cavity 151, but also increase the contact and heat exchange area between the steam and the water collection box 15, increase the amount of steam condensed into water during the flow process, and also guide the steam to flow towards the exhaust port 155.

[0149] Please refer to Figure 4 , in some embodiments of the present application, the flow disturbance structure 157 includes at least one first flow disturbance wall 1571 protruding from the top wall of the water collection cavity 151. The first flow disturbance wall 1571 is disposed between the inlet 153 and the exhaust port 155 of the water collection cavity 151 and is spaced from the bottom wall of the water collection cavity 151.

[0150] In this embodiment, the flow disturbing structure 157 includes at least one first flow disturbing wall 1571 protruding from the top wall of the water collecting cavity 151. When two or more first flow disturbing walls 1571 are provided, the first flow disturbing walls 1571 are arranged side by side between the inlet 153 and the exhaust port 155 of the water collecting cavity 151. The first flow disturbing wall 1571 can extend vertically towards the bottom wall or extend obliquely, and a gas passing channel is formed by arranging the first flow disturbing wall 1571 at an interval from the bottom wall of the water collecting cavity 151. With the arrangement of the first flow disturbing wall 1571, after the steam flows in from the inlet 153 at the top of the water collecting cavity 151, part of the steam will collide with the first flow disturbing wall 1571 and flow along the first flow disturbing wall 1571 towards the opening below the first flow disturbing wall 1571 and flow towards the exhaust port 155. During this process, more energy loss of the steam occurs, the flow path and flow channel time of the steam in the water collecting cavity 151 are prolonged, the contact and heat exchange area between the steam and the water collecting box 15 is increased, and the steam is drained towards the bottom wall side by the first flow disturbing wall 1571, and the steam can also contact the already condensed condensed water, so that more steam can be condensed into water and the steam discharged outwards is reduced. In addition, due to the blocking of the first flow disturbing wall 1571, the flow speed of the steam can be slowed down to prevent the steam from flowing out quickly.

[0151] Please refer to Figure 4 , in some embodiments of the present application, the flow disturbing structure 157 further includes at least one second flow disturbing wall 1573 protruding from the bottom wall of the water collecting cavity 151. The second flow disturbing wall 1573 is arranged between the inlet 153 and the exhaust port 155 of the water collecting cavity 151 at an interval and is arranged at an interval from the top wall of the water collecting cavity 151. The second flow disturbing wall 1573 and the first flow disturbing wall 1571 are arranged in an alternating manner.

[0152] In this embodiment, the flow disturbance structure 157 further includes at least one second flow disturbance wall 1573 disposed on the bottom wall of the water collecting chamber 151. The second flow disturbance wall 1573 is disposed between the inlet 153 and the exhaust port 155 of the water collecting chamber 151 and is spaced from the top wall of the water collecting chamber 151, so as to form a gas passage between the second flow disturbance wall 1573 and the top wall. When at least two second flow disturbance walls 1573 are provided, the second flow disturbance walls 1573 are arranged side by side. With such an arrangement, a first flow disturbance wall 1571 and a second flow disturbance wall 1573 are formed in the water collecting chamber 151 and are arranged in sequence between the inlet 153 and the exhaust port 155 of the water collecting chamber 151. After the steam flows into the water collecting chamber 151 from the inlet 153, it will first contact the first flow disturbance wall 1571 closest to the inlet 153 and be drained toward the bottom wall side. After passing through the first flow disturbance wall 1571, the remaining part of the steam contacts the second flow disturbance wall 1573 and rises, flowing over the upper end of the second flow disturbance wall 1573. During this process, the steam can also exchange heat with the second flow disturbance wall 1573 and there is energy loss at the second flow disturbance wall 1573, so that more steam is condensed into water, reducing the outward discharge of steam. In addition, due to the blocking of the first flow disturbance wall 1571 and the second flow disturbance wall 1573, the flow velocity of the steam is slowed down, preventing the steam from flowing out quickly.

[0153] In an embodiment of the present application, the cooking appliance 100 further includes a temperature sensor disposed on the appliance body 10 for detecting the temperature of the cooking space 111.

[0154] In this embodiment, the cooking appliance 100 further includes a temperature sensor for detecting the temperature of the cooking space 111. The temperature sensor may be disposed outside the cooking pot body 11 that forms the cooking space 111 in the cooking appliance 100, or may be disposed on the lid body 13 and at the opening position of the cooking space 111, or may be disposed directly in the cooking space 111 to detect the temperature of the food material. With such an arrangement, the temperature of the cooking space 111 can be detected by the temperature sensor to confirm the cooking stage of the food material, and the operating states of various structures in the cooking appliance 100 can be controlled according to the cooking stage, such as controlling the heating duration and heating power of the heating structure, or controlling the start / stop and rotation speed of the heat exchange fan 50.

[0155] Please refer to Figure 15 , the present application also proposes a control method for a cooking appliance 100. This control method can be applied to the cooking appliance 100 in any of the foregoing embodiments. The control method includes the following steps:

[0156] Step S10, before the boiling stage, control the heat exchange fan 50 of the cooking appliance 100 to operate for a preset time, and obtain the working current value of the heat exchange fan 50;

[0157] Step S20, issue an instruction to install the condensation module 30 under the condition that the working current value is greater than the preset current value.

[0158] In the embodiment of the present application, the heat exchange fan 50 provided in the cooking appliance 100 is used to exchange heat for the condensation module 30. In this embodiment, it is possible to determine whether the condensation module 30 is installed in the cooking appliance 100 by detecting the working current of the heat exchange fan 50. For example, it is assumed that a channel for guiding the cold air blown by the heat exchange fan 50 is provided in the cooking appliance 100, and the condensation module 30 is arranged in this channel. For the heat exchange fan 50, the calculation method of its power can be calculated by the energy of the driven air flow. Fan power = fan flow * air pressure / 1000 / 3600 * fan efficiency (kw), where the fan flow = cross-sectional area of the channel * wind speed; in addition, the power of the heat exchange fan 50 can also be calculated from the working current and working voltage. Fan power = working current * working voltage * fan efficiency (kw). That is, under the condition that the working voltage, wind speed, and air pressure of the heat exchange fan 50 are constant, the working current of the heat exchange fan 50 is positively correlated with the cross-sectional area of the channel for cold air flow. That is, when the condensation module 30 is installed in the cooking appliance 100, due to the obstruction of the condensation module 30, the cross-sectional area of the channel for cold air flow becomes smaller, and at this time, the working current of the heat exchange fan 50 is also smaller; when the condensation module 30 is not installed in the cooking appliance 100, the cross-sectional area of the channel for cold air flow is larger, and at this time, the working current of the heat exchange fan 50 increases.

[0159] Among them, the working current value of the heat exchange fan 50 when the condensation module 30 is installed is set as the preset current value. When the cooking appliance 100 starts to run, at least before entering the boiling stage, the heat exchange fan 50 is started to run for a period of time. If it is detected that the working current during the operation of the heat exchange fan 50 is greater than the preset current value, it is confirmed that the condensation module 30 is not installed in the cooking appliance 100. At this time, the cooking appliance 100 can issue an instruction to install the condensation module 30. The instruction can be an indication signal, such as a buzzer, an indicator light, or information sent to the terminal, etc., to prompt the user to install the condensation module 30 to ensure that when using a steam-free or micro-steam cooking mode, the steam generated during the cooking process can be condensed by the condensation module 30, reducing steam emissions.

[0160] In addition, in some embodiments, after a preset time period after issuing the instruction, when it is detected that the working current of the heat exchange fan 50 does not exceed the preset current value during the operation of the heat exchange fan 50, it is confirmed that the condensation module 30 has been installed. At this time, the normal cooking program can be run; if the detected working current is still greater than the preset current value, the cooking program can be directly stopped, or operations such as repeating the instruction to install the condensation module 30 can be performed until the preset number of times or until it is confirmed that the condensation module 30 has been installed.

[0161] The present application also provides a readable storage medium storing program instructions, which, when executed by a processor, can implement the control method in the foregoing embodiments.

[0162] Through the description of the above embodiments, those skilled in the art can clearly understand that the above embodiment methods can be implemented by means of software plus a necessary general hardware platform. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation. Based on such an understanding, the technical solution of the present application, in essence or the part that contributes to the prior art, can be embodied in the form of a software product.
