[0042] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0043] Figure 1A 1 is a schematic diagram showing a three-dimensional structure of an oven 100 according to an embodiment of the present application. Figure 1B 1 shows a schematic diagram of the three-dimensional structure of an oven 100 according to an embodiment of the present application, wherein the door assembly is omitted; Figure 1C A schematic perspective structural diagram of the oven 100 according to an embodiment of the present application is shown from another perspective, wherein the top plate of the outer shell 111 of the box body 110 and the side plates of the outer shell 111 are hidden; Figure 2A A schematic diagram of the three-dimensional structure of the heating device 120, the convection device 130 and the humidifying device 140 of the oven 100 according to an embodiment of the present application is shown;

[0044] Figure 2B A side structural schematic diagram of the heating device 120, the convection device 130 and the humidifying device 140 of the oven 100 according to an embodiment of the present application is shown.

[0045] Reference Figures 1A to 2B The oven 100 of the present embodiment includes a housing 110, a heating device 120, a convection device 130, and a humidifying device 140. The housing 110 includes a main body, which defines a cavity 110a therein. The heating device 120 is disposed within the housing 110 and is configured to heat the cavity 110a. The convection device 130 is disposed within the housing 110 and includes a fan turbine 131. The fan turbine 131 is configured to generate an airflow radially outward when rotating, and the airflow passes through the heating device 120. The humidifying device 140 includes a water pump 141, a water inlet pipe 142 and an atomizer 146. The water inlet pipe 142 is connected between the output end of the water pump 141 and the atomizer 146. The water pump 141 is used to pump liquid water to the atomizer 146 through the water inlet pipe 142. The atomizer 146 is used to convert liquid water into steam; wherein, the atomizer 146 is arranged at the center position of the fan turbine 131, and the outer peripheral wall of the atomizer 146 has a plurality of steam outlets 146a distributed at intervals in its circumferential direction.

[0046] The oven 100 of the present embodiment utilizes atomizer 146 to generate steam to humidify food, thereby reducing moisture loss during the baking process, thereby improving the food's taste and reducing nutritional loss. Furthermore, by positioning atomizer 146 at the center of fan turbine 131 and forming a plurality of circumferentially spaced steam outlets 146a around the outer periphery of atomizer 146, the oven 100 of this embodiment can evenly spray the mist generated by atomizer 146 into cavity 110a, uniformly humidifying the food and preventing localized over-drying or over-wetting of the food, thereby improving the overall taste of the food.

[0047] The input end of water pump 141 is connected to an input pipe 143 for receiving a water source. Input pipe 143 may be equipped with a valve 144 and a flow meter 145. Valve 144 regulates the flow of water entering input pipe 143, while flow meter 145 monitors the flow of water entering input pipe 143. This allows the flow of water entering water inlet pipe 142 to be adjusted based on the type of food and its water requirement.

[0048] In one embodiment, reference Figure 2A The outer peripheral wall of the atomizer 146 has multiple rows of steam outlets 146a evenly spaced in the circumferential direction, and each row of steam outlets 146a includes multiple steam outlets 146a evenly spaced in the radial direction to increase the amount of mist output and allow the water mist to diffuse outward in the circumferential and radial directions of the atomizer 146, thereby improving the uniformity of the distribution of the water mist in the cavity 110a.

[0049] In one embodiment, the fan turbine 131 includes a turbine body 1311 and a plurality of blades 1312. The turbine body 1311 is hollow and annular. The plurality of blades 1312 are spaced apart circumferentially around the turbine body 1311, with adjacent blades 1312 defining an air flow path. The atomizer 146 is disposed at the center of the turbine body 1311. The rotation of the blades 1312 of the fan turbine 1311 disperses the water mist sprayed from the atomizer 146 through the air flow path into the cavity 110a. The atomizer 146 located at the center of the turbine body 1311 is spaced equidistant from the blades 1312 distributed circumferentially around the turbine body 1311. This allows the water mist sprayed from the atomizer 146 to be evenly dispersed within the cavity 110a, thereby further facilitating uniform humidification of the food.

[0050] In one embodiment, the heating device 120 includes a heating tube assembly comprising a plurality of heating tubes 121 arranged side by side. The plurality of heating tubes 121 are bent together to define a housing space. A fan turbine 131 is disposed within the housing space, such that the plurality of heating tubes 121 surround the fan turbine 131. Water mist is blown toward the periphery of the fan turbine 131 and directly heated by the plurality of heating tubes 121 distributed around the periphery, rapidly converting the water mist into hot steam, thereby rapidly humidifying the food. Furthermore, by bending the heating tubes 121 to define a space for accommodating the fan turbine 131, the space occupied by the fan turbine 131 within the cavity 110a can be reduced.

[0051] like Figure 2B As shown, multiple heating tubes 121 are arranged side by side in the front-to-back direction and bent together to define an accommodation space. Each heating tube 121 has a first tube section and a last tube section extending toward the side wall of the cavity 110a. Each heating tube 121 bends and extends from the end of its first tube section to the beginning of its last tube section, thereby defining the accommodation space.

[0052] The first and last sections of each heating tube 121 are connected to the positive and negative electrodes of the power supply, respectively. When the oven 100 is powered on, the resistance wires of each heating tube 121 generate heat, which is then transferred to the entire cavity 110a by radiation and conduction, thereby baking the food.

[0053] In one embodiment, reference Figures 1A to 1C The main body includes a top plate 112 and a rear side plate. The fan turbine 131 is installed on the rear side plate of the main body and is located inside the cavity 110a. The atomizer 146 is installed on the rear side plate of the main body and is located inside the cavity 110a. The water pump 141 is installed on the rear side plate of the main body and is located outside the cavity 110a. Among them, the top plate 112 is provided with a through hole 112a, and the water inlet pipe 142 is passed through the through hole 112a, so that the two ends of the water inlet pipe 142 are connected to the water pump 141 and the atomizer 146 respectively. In this way, the water inlet pipe 142 is introduced from the outside of the cavity 110a into the interior of the cavity 110a to meet the water supply demand of the atomizer 146.

[0054] like Figure 1A and 1C As shown, the convection device 130 further includes a motor 132 for driving the fan turbine 131 to rotate. The motor 132 is mounted on the outer side of the rear side plate of the body. The rear side plate 113 of the housing 111 of the box body 110 is mounted with a bearing plate, and the motor 132 is arranged on the bearing plate.

[0055] The water pump 141 is mounted on the outside of the rear side panel, adjacent to the right side of the bottom end of the rear side panel. The water inlet pipe 142 extends from the bottom of the partition space to the right, passes through the right side panel 114 of the main body, and extends upward to the top of the main body top panel 112. It enters the cavity 110a through the through hole 112a of the top panel 112, thus connecting the water inlet pipe 142 to the atomizer 146. The water inlet pipe 142 can be fixed to the right side panel 114 of the main body.

[0056] The housing 110 further includes a shell 111, which is wrapped around the periphery of the body to cover the water inlet pipe 142. The rear side plate 113 of the shell 111 defines a mounting opening, and the motor 132 is mounted on the rear side plate of the body through the mounting opening.

[0057] The front side of the body has an opening 110b, which connects the outside and inside of the cavity 110a; the box body 110 also includes a door assembly, which includes at least one door 160, which is rotatably installed on the front side of the box body 110 to open and close the opening 110b.

[0058] In one embodiment, the door assembly includes two door bodies 160 arranged side by side, and the two door bodies 160 are rotatably arranged on the box body 110 to open and close the opening 110b together. Figure 1A As shown, two door bodies 160 are connected to the opening 110b on the front side of the main body, forming a bifold door. The door bodies 160 can rotate about a vertical axis to open and close the cavity 110a. Of course, in another example, the door assembly may include only one door body 160, which can rotate about a vertical axis or a horizontal axis to open and close the cavity 110a.

[0059] In one embodiment, reference Figure 1B A first sealing member 150150 is provided on the inner edge of the opening 110b. The first sealing member 150 extends along the circumference of the inner edge of the opening 110b. The first sealing member 150 is used to seal the gap between the outer edge of the door 160 and the inner edge of the opening 110b when the door 160 is closed. In this way, when the door 160 is closed, the outer edge of the door 160 and the inner edge of the opening 110b are sealed to prevent heat from leaking out through the edge between the two.

[0060] Figure 3 1 shows an exploded schematic diagram of the door 160, the second sealing member 190, the cover assembly 170 and the locking mechanism 180 of the oven 100 according to an embodiment of the present application. Figure 4 A schematic exploded view of the cover assembly 170 of the oven 100 according to an embodiment of the present application is shown.

[0061] Reference Figure 3A second sealing member 190 is provided at the adjacent portion of the two door bodies 160 . The second sealing member 190 is used to seal the gap between the two door bodies 160 at the adjacent portion to prevent heat from leaking out from the adjacent portion between the two door bodies 160 .

[0062] The two door bodies 160 are respectively a first door body and a second door body. When the two door bodies 160 are in a closed state, the first side wall of the first door body is adjacent to the second side wall of the second door body.

[0063] In one embodiment, the second sealing member 190 includes a first bent portion 191 and a second bent portion 192, wherein the first bent portion 191 is fixedly connected to the first side wall. When both doors 160 are closed, the first bent portion 191 seals the gap between the first and second side walls, and the second bent portion 192 abuts against the front surface of the second door. In this manner, the first bent portion 191 seals the gap between the two doors 160, while the second bent portion 192 covers the front side of the gap between the two doors 160, thereby enhancing the sealing between the two doors 160.

[0064] It can be understood that the second sealing member 190 is made of a flexible material, and the second bending portion 192 deforms as the second door body is opened and closed, and does not interfere with the opening and closing of the second door body.

[0065] In one embodiment, the door 160 is provided with a window 161, which is provided with a cover assembly 170. The cover assembly 170 includes two cover plates 171 spaced apart in a direction normal to the plane in which the window 161 is located. The double-layer cover plates 171 isolate the cavity 110a of the oven 100 from the external environment, reducing heat transfer between the hot air in the cavity 110a and the external environment, thereby reducing heat loss. The cover plates 171 can be made of a transparent material, such as heat-resistant glass. The user can directly observe the state of food inside the cavity 110a through the cover plates 171.

[0066] In one embodiment, the cover plate assembly 170 further includes a third seal 172, which comprises a seal body 1721 extending circumferentially along the inner edge of the window 161 and two sealing protrusions 1722 disposed on the seal body 1721. The two sealing protrusions 1722 are spaced apart in the normal direction of the plane in which the window 161 is located, and are formed by protrusions on the inner surface of the seal body 1721. The two sealing protrusions 1722 respectively abut against the side surfaces of the two cover plates 171. In this way, the gap between the two cover plates 171 is sealed by the third seal 172.

[0067] Reference Figure 4The normal direction of the plane where the window 161 is located is recorded as the front-to-back direction. The front sealing protrusion 1722 is formed by the front edge protrusion of the inner surface of the sealing body 1721, and the rear sealing protrusion 1722 is formed by the rear edge protrusion of the inner surface of the sealing body 1721. The rear surface of the front cover plate 171 abuts against the front sealing protrusion 1722, and the front surface of the rear cover plate 171 abuts against the rear sealing protrusion 1722.

[0068] In one embodiment, the cover plate assembly 170 also includes a support frame assembly, which includes an inner frame 173 and an outer frame 174. The inner frame 173 is arranged on the inner side of the sealing body 1721, and the outer frame 174 is arranged on the outer side of the third sealing member 172. The two cover plates 171 are located on the inner side of the outer frame 174 and are respectively located on opposite sides of the inner frame 173 in the normal direction of the plane where the window 161 is located.

[0069] The support frame assembly provides support for the third seal 172 through the inner frame 173 and the outer frame 174, and limits the third seal 172 in the vertical direction and in the horizontal direction perpendicular to the front-to-back direction, so that the third seal 172 is deformed only in the front-to-back direction, so that the two sealing protrusions 1722 are evenly abutted against the front surface of the front cover plate 171 and the rear surface of the rear cover plate 171, respectively, thereby improving the sealing between the two cover plates 171.

[0070] In addition, the support frame assembly serves to isolate the two cover plates 171 , thereby reducing the heat transfer between the hot air in the cavity 110 a and the external environment.

[0071] Figure 5 A schematic exploded view of the locking mechanism 180 of the oven 100 according to an embodiment of the present application is shown.

[0072] In one embodiment, reference Figure 3 and Figure 5 The oven 100 further includes a locking mechanism 180. There is at least one locking mechanism 180, which is provided corresponding to at least one door 160. The locking mechanism 180 includes a door handle 181, a transmission assembly 182, and a lock tongue 183. The door handle 181 is rotatably provided on the outer surface of the door 160. The transmission assembly 182 is provided inside the door 160 and is in transmission connection with the door handle 181. The lock tongue 183 is connected to the transmission assembly 182. When the door handle 181 rotates, the transmission assembly 182 drives the lock tongue 183 to move, so that the lock tongue 183 engages or disengages with the locking engagement portion of the housing 110. The door handle 181 drives the lock tongue 183 to move via the transmission assembly 182, thereby locking or unlocking the door 160 and the housing 110. This prevents the oven 100 from being accidentally opened, improves safety, and strengthens the seal between the door 160 and the housing 110.

[0073] In the example where there are two door bodies 160 , there are two locking mechanisms 180 , and the two locking mechanisms 180 correspond to the two door bodies 160 respectively, to respectively lock or unlock the two door bodies 160 .

[0074] The locking fitting portion can be a bayonet or a snap ring formed on the box body 110. The handle drives the lock tongue 183 to be inserted into the locking fitting portion through the transmission assembly 182 to achieve locking, and the handle drives the lock tongue 183 to be disengaged from the locking fitting portion through the transmission assembly 182 to achieve unlocking.

[0075] In one embodiment, the locking mechanism 180 includes two locking tongues 183, which are respectively disposed adjacent to the top and bottom of the door body 160. There are two locking mating portions, each corresponding to the two locking tongues 183. The transmission assembly 182 includes a base, a gear 1822, two racks 1823, and two transmission rods 1824. The gear 1822 and racks 1823 are housed within the base. The gear 1822 is in transmission connection with the door handle 181. The two racks 1823 respectively mesh with the gear 1822 and move in opposite directions vertically when the gear 1822 rotates. The two transmission rods 1824 are respectively connected to the two locking tongues 183. The two locking tongues 183 lock the door body 160 to the housing 110 at both the top and bottom, thereby enhancing the locking effect of the door body 160. The two locking tongues 183 can be locked or unlocked synchronously or asynchronously by cooperating with a gear 1822, two racks 1823 and two transmission rods 1824. The structure is ingenious, the cooperation is smooth, and it is not easy to malfunction.

[0076] Two locking mating portions are provided at the top and bottom of the housing 110, respectively, and engage with two locking tongues 183 to achieve locking or unlocking. Two racks 1823 are located on opposite sides of the gear 1822. The normal direction is designated as the front-to-back direction, and the direction perpendicular to the normal direction in the horizontal plane is designated as the left-to-right direction. The two racks 1823 are located on either side of the left side of the gear 1822.

[0077] The base includes two front and rear covers 1821, which define a space for accommodating a gear 1822 and two racks 1823. Each cover 1821 defines a through hole. The door handle 181 is provided with a rotating shaft 184, and the gear 1822 has a mating hole for the rotating shaft 184. The rotating shaft 184 is sequentially inserted through the through hole of the front cover 1821, the mating hole of the gear 1822, and the through hole of the rear cover 1821.

[0078] The door body 160 has a vertical channel for accommodating the locking mechanism 180 and for the movement of the lock tongue 183. The locking mechanism 180 is accommodated in the channel. The door body 160 is formed with a door hole 162 for the rotating shaft 184 of the door handle 181 to cooperate with. The rotating shaft 184 passes through the door hole 162 and passes through the through hole of the cover part 1821 on the front side.

[0079] The door handle 181 is rotatable between a first position and a second position. When the door handle 181 is rotated to the first position, the door body 160 and the housing 110 are locked. When the door handle 181 is rotated to the second position, the door body 160 and the housing 110 are unlocked. The door handle 181 also has an intermediate position between the first and second positions. When the door handle 181 is rotated to the intermediate position, one of the locking tongues 183 is unlocked from the corresponding locking mating portion, and the other locking tongue 183 is disengaged from the corresponding locking mating portion.

[0080] In one embodiment, the first position is a vertical position, the intermediate position is a horizontal position, and the second position is an inclined position forming an acute angle with the horizontal direction.

[0081] During the unlocking process, the user rotates door handle 181 clockwise, which drives gear 1822 clockwise via shaft 184. Gear 1822 lowers upper rack 1823 and raises lower rack 1823, causing both upper and lower lock tongues 183 to rise synchronously. When door handle 181 is rotated to the horizontal position, upper lock tongue 183 disengages from the upper locking engagement, while lower lock tongue 183 remains locked with the lower locking engagement, achieving primary unlocking. As door handle 181 continues to rotate clockwise from the horizontal position, lower lock tongue 183 continues to rise along with lower rack 1823. When door handle 181 is rotated to the second position, lower lock tongue 183 disengages from the lower locking engagement, achieving secondary unlocking.

[0082] During the locking process, the user rotates door handle 181 counterclockwise, which drives gear 1822 counterclockwise via shaft 184. Gear 1822 drives upper rack 1823 upward and lower rack 1823 downward, causing upper and lower lock tongues 183 and 183 to descend simultaneously. When door handle 181 is rotated to a horizontal position, upper lock tongue 183 engages and locks with the upper locking mating portion, while lower lock tongue 183 has not yet engaged with the lower locking mating portion, thus achieving primary locking. As door handle 181 continues to rotate counterclockwise from the horizontal position, lower lock tongue 183 continues to rise along with lower rack 1823. When door handle 181 is rotated to a vertical position, lower lock tongue 183 engages and locks with the lower locking mating portion, achieving secondary locking.
