Description

Technical Field

[0001] This utility model relates to the technical field of steam ovens, and in particular to an evaporation plate assembly and a steam oven. Background Technology

[0002] Steam ovens typically lack drainage systems. However, due to technological limitations, current steam ovens often leave residual water after the steaming function. Furthermore, food scraps may fall and remain during the switching between steam and grill functions, resulting in wastewater. To prevent limescale buildup in the water tank, using more expensive purified water is generally recommended. The presence of residual water leads to water waste and increased water costs. Utility Model Content

[0003] Given the problem of wastewater residue after the steaming function in existing steam ovens, which leads to high operating costs, it is necessary to provide an evaporation plate assembly and a steam oven.

[0004] An evaporation tray assembly for a steam oven includes:

[0005] The evaporator plate body is equipped with a drainage hole;

[0006] A drain cylinder is installed on the evaporator plate body and has an inlet, an outlet, a first cavity communicating with the inlet, a second cavity communicating with the outlet, and a water passage communicating with the first cavity and the second cavity, wherein the inlet is communicating with the drain hole;

[0007] A filter basket is installed inside the first cavity and covers the inlet for filtering food residue in the residual water.

[0008] An oil filter screen, covering the water passage and used to filter oil droplets in the residual water; and

[0009] A valve is installed in the drain cylinder and is used to control the flow of water in the water passage.

[0010] With this design, the residual water is filtered twice through the filter basket and the oil filter screen during the collection process. This allows food residue and oil stains generated during the switching between steam and bake functions of the steam oven to be collected in the first chamber, preventing them from entering the second chamber. This makes cleaning easier for users and minimizes the burden of subsequent residual water treatment.

[0011] In one embodiment, the evaporator assembly further includes a water tank, a drain pipe connecting the outlet and the water tank, and a filter element installed in the drain pipe, the filter element being used to filter organic matter in the residual water.

[0012] This setup allows for the filtration of organic matter in the residual water by adding a filter cartridge, eliminating the need for an external filter unit. The water collected in the storage tank can be pumped back into the evaporator plate to generate steam, thus achieving the recycling and reuse of residual water.

[0013] In one embodiment, the filter element has a first water-stopping surface, a third water-stopping surface, a second water-stopping surface arranged sequentially at intervals, a first connecting port and a second connecting port located on the first water-stopping surface and the second water-stopping surface respectively, a diversion channel extending from the first connecting port to the third water-stopping surface, and a converging channel extending from the second connecting port to the third water-stopping surface.

[0014] The outer edges of the first and second water-stop surfaces are respectively circumferentially connected to the inner wall of the drain pipe, and the outer edge of the third water-stop surface is spaced apart from the inner wall of the drain pipe.

[0015] With this configuration, a water-dividing zone is formed between the first and third water-stopping surfaces, and a water-collecting zone is formed between the second and third water-stopping surfaces. The diversion and collection channels in the filter element create a water flow path that first divides and then collects, increasing the filtration area within the limited space of the drain pipe and improving the filtration effect.

[0016] In one embodiment, the filter element further has multiple first filter channels communicating with the diversion channel; and / or

[0017] The filter element also has multiple second filter channels connected to the confluence channel.

[0018] This design creates a tree-like channel within the filter element, further enhancing filtration and flow convergence, and facilitating full utilization of the filter element's internal space while reducing internal clogging.

[0019] In one embodiment, the drain cylinder includes a cylinder body providing the inlet and the outlet, and a waterproof baffle providing the water passage, the waterproof baffle being detachably installed in the cylinder body, and the oil filter screen being installed on the waterproof baffle.

[0020] This design makes it easy to remove the waterproof partition to take out the dirt from the drain pipe, thus meeting the user's cleaning needs.

[0021] In one embodiment, the bottom wall of the filter basket is provided with an installation hole, and the filter oil screen is located in the first cavity and extends around the water passage to the installation hole to divide the first cavity into a first water storage space that connects the installation hole and the water passage and a second water storage space that surrounds the first water storage space.

[0022] The valve includes a fixed shell installed on the filter basket and covering the mounting hole, and a movable rod movably connected to the fixed shell. The movable rod is located in the first water storage space and is used to block the water passage.

[0023] This design, through the shape of the oil filter screen, isolates a relatively clean first water storage space in the drain cylinder, ensuring that only residual water free of oil and residue flows through the water passage, thus preventing blockage. At the same time, this first water storage space also provides installation and movement space for the valve's movable rod, ensuring the normal operation of the valve.

[0024] In one embodiment, the movable rod includes a first rod body and a plurality of snap-fit ​​blocks spaced circumferentially from the first rod body. Each snap-fit ​​block has a snap-fit ​​surface extending obliquely circumferentially. The valve further includes a rotary telescopic assembly mounted on the fixed housing and driven to connect to the snap-fit ​​blocks. The rotary telescopic assembly includes:

[0025] The pressing rod has multiple abutment blocks spaced apart in a circumferential direction, and the abutment blocks are used to abut against the locking surface;

[0026] The positioning cylinder has a first stop groove and a second stop groove arranged alternately in the circumferential direction, wherein the distance between the bottom of the first stop groove and the bottom of the positioning cylinder is smaller than the distance between the bottom of the second stop groove and the bottom of the positioning cylinder.

[0027] An elastic element, one end of which is fixedly connected to the fixed shell and the other end of which is fixedly connected to the first rod, is used to cause the first rod to drive the snap block closer to the pressing rod and the positioning cylinder.

[0028] This design gives the valve two positions, corresponding to the two states of the movable rod blocking the water passage and moving away from the water passage, respectively. When the pressing rod pushes the locking block out of the first position slot, under the guidance of the locking surface and the push of the elastic element, releasing the pressing rod will allow the locking block to rotate automatically and enter the second position slot, thus realizing the position switching.

[0029] In one embodiment, the second gear slot has a first guide surface, a stop surface and a second guide surface connected sequentially in the circumferential direction. The first guide surface is connected to the opening of the first gear slot, and the second guide surface is connected to another adjacent first gear slot. When the locking block is located in the second gear slot, the first guide surface is in contact with the locking surface.

[0030] With this design, the positioning cylinder and the movable rod are firmly engaged, making it difficult for them to rotate relative to each other.

[0031] In one embodiment, the circumferential length of the snap-fit ​​surface is greater than the circumferential length of the first guide surface.

[0032] This design facilitates fully automatic gear switching during pressing. When the locking block engages with the second gear slot, a portion of the locking surface remains within the circumferential range of the first gear slot. When pressing continues, the abutment block can push the locking block out of the second gear slot until the locking surface reaches the junction of the second guide surface and the stop surface. Under the pushing action of the elastic element, the movable rod is guided to rotate by the locking block and re-enters the adjacent first gear slot.

[0033] This application also provides a steam oven, including:

[0034] Inner liner body; and

[0035] As described above, the evaporator assembly is installed on the bottom wall of the inner liner body.

[0036] With this setup, the residual water is filtered into clean water that can be used in the steaming function through the triple filtration of the evaporator plate assembly, avoiding the problem of limescale buildup in the water tank. The press operation is simple and easy to understand, and cleaning is convenient. Attached Figure Description

[0051] Steam ovens typically lack drainage systems. However, due to technological limitations, current steam ovens often leave residual water after the steaming function. Furthermore, food scraps may fall and remain during the switching between steam and grill functions, resulting in wastewater. To prevent limescale buildup in the water tank, using more expensive purified water is generally recommended. The presence of residual water leads to water waste and increased water costs.

[0052] Therefore, it is necessary to provide an evaporator assembly and a steam oven that can reduce wastewater residue and lower water costs.

[0053] Please see Figure 1 , Figure 1 This is a schematic diagram of the evaporator assembly in one embodiment of the present invention. Figure 2 for Figure 1 The diagram shows a cross-sectional view of the evaporator assembly excluding the evaporator body 10. (See diagram for reference.) Figure 1 and Figure 2 As shown, the evaporator assembly includes an evaporator body 10, a drain cylinder 20, a filter basket 50, an oil filter screen 60, and a valve 70. The evaporator body 10 has a drain hole. The drain cylinder 20 is installed on the evaporator body 10 and has an inlet 201, an outlet 202, a first cavity 203 connected to the inlet 201, a second cavity 204 connected to the outlet 202, and a water passage 205 connecting the first cavity 203 and the second cavity 204. The inlet 201 is connected to the drain hole. The filter basket 50 is installed inside the first cavity 203 and covers the inlet 201 to filter food residue in the residual water. The oil filter screen 60 covers the water passage 205 to filter oil droplets in the residual water. The valve 70 is installed on the drain cylinder 20 to control the flow of water in the water passage 205. In this way, during the process of collecting residual water, the residual water is filtered twice through the filter basket 50 and the oil filter 60, so that the food residue and oil stains generated during the switching between steaming and baking functions of the steam oven are collected into the first chamber 203 and will not enter the second chamber 204. This makes it convenient for users to clean and also reduces the pressure of subsequent residual water treatment as much as possible.

[0054] like Figure 2 As shown, the evaporator assembly further includes a water storage tank 40, a drain pipe 30, and a filter element 80. The drain pipe 30 connects the outlet 202 and the water storage tank 40, and the filter element 80 is installed inside the drain pipe 30 and used to filter organic matter in the residual water. Specifically, as... Figure 3 As shown, Figure 3 for Figure 2The diagram shows a partial enlarged view of the structure at point A, i.e., at the filter element 80. The filter element 80 has a first water-stopping surface 801, a third water-stopping surface 803, a second water-stopping surface 802 arranged sequentially at intervals, a first connecting port 804 and a second connecting port 805 located at the first water-stopping surface 801 and the second water-stopping surface 802 respectively, a diversion channel 806 extending from the first connecting port 804 to the third water-stopping surface 803, and a converging channel 807 extending from the second connecting port 805 to the third water-stopping surface 803. The outer edges of the first water-stopping surface 801 and the second water-stopping surface 802 are respectively connected to the inner wall of the drain pipe 30, and the outer edge of the third water-stopping surface 803 is arranged at intervals from the inner wall of the drain pipe 30. A water-dividing zone is formed between the first water-stopping surface 801 and the third water-stopping surface 803, and a water-collecting zone is formed between the second water-stopping surface 802 and the third water-stopping surface 803. The arrangement of the diversion channel 806 and the confluence channel 807 in the filter element 80 creates a water flow path that first diverts and then converges, increasing the filtration area within the limited space of the drain pipe 30 and improving the filtration effect. Optionally, in one embodiment provided in this application, the filter element 80 also has a plurality of first filtration channels 808 connected to the diversion channel 806 and a plurality of second filtration channels 809 connected to the confluence channel 807. This forms a tree-like channel in the filter element 80, further increasing the filtration and confluence effects, which is beneficial for making full use of the internal space of the filter element 80 and reducing internal clogging of the filter element 80.

[0055] Please refer to the following: Figure 2 , Figure 4 and Figure 5 , Figure 4 for Figure 2 The diagram shown is a structural schematic of the filter screen at position 60. Figure 5 for Figure 4A schematic diagram of the structure when the water passage 205 is blocked. Optionally, in one embodiment provided in this application, the drain cylinder 20 specifically includes a cylinder 21 providing an inlet 201 and an outlet 202, and a waterproof baffle 22 providing a water passage 205. The waterproof baffle 22 is detachably installed inside the cylinder 21, and an oil filter 60 is installed on the waterproof baffle 22. This facilitates the removal of the waterproof baffle 22 to remove dirt from the drain cylinder 20. Optionally, the oil filter 60 can also be detachably installed on the waterproof baffle 22 for easy cleaning and replacement. In this embodiment provided in this application, the bottom wall of the filter basket 50 has a mounting hole 501. The filter oil screen 60 is located inside the first cavity 203 and extends around the water passage 205 to the mounting hole 501. This separates a first water storage space and a second water storage space surrounding the first water storage space in the first cavity 203. The first water storage space connects the mounting hole 501 and the water passage 205. The valve 70 includes a fixed shell 71 and a movable rod 72, wherein the fixed shell 71 is mounted on the filter basket 50. The bottom wall of the valve 70 is covered by the mounting hole 501. The movable rod 72 is movably connected to the fixed shell 71. The movable rod 72 is located in the first water storage space and is used to block the water passage 205. In actual use, the residual water enters the second water storage space after being filtered by the filter basket 50 to remove residue, and then enters the first water storage space after being filtered by the filter oil screen 60. The movable rod 72 of the valve 70 controls whether the first water storage space and the water passage 205 are connected, thereby controlling whether the residual water after secondary filtration can enter the second cavity 204. This application isolates a relatively clean first water storage space in the drain cylinder 20 by designing the shape of the filter oil screen 60, ensuring that only residual water without oil and residue flows through the water passage 205, avoiding blockage of the water passage 205. At the same time, the first water storage space also provides installation space and movement space for the movable rod 72 of the valve 70, ensuring the normal operation of the valve 70.

[0056] Specifically, such as Figure 1 and Figure 4 As shown, in one embodiment provided by this application, the bottom wall of the filter basket 50 is provided with a water passage hole 502 and the side wall is provided with a water passage groove 503. The water passage groove 503 extends vertically. This design ensures smooth water passage and avoids clogging of the filter basket 50 when there is too much residue.

[0057] like Figure 4 and Figure 6 As shown, Figure 6This is a schematic diagram of the structure of a rotary telescopic assembly 73 provided in this application. Optionally, in one embodiment provided in this application, the movable rod 72 includes a first rod body 721 and a plurality of snap-fit ​​blocks 722 spaced circumferentially around the outer periphery of the first rod body 721, and the valve 70 further includes a rotary telescopic assembly 73 mounted on the fixed housing 71 and driven to be connected to the snap-fit ​​blocks 722. Specifically, the rotary telescopic assembly 73 includes a pressing rod 731, a positioning cylinder 732, and an elastic element 733. The pressing rod 731 includes a second rod body 7311 and abutting blocks 7312 spaced circumferentially from the second rod body 7311 for abutting against the locking blocks 722. The locking blocks 722 have locking surfaces 7221 that gradually approach the bottom of the positioning cylinder 732 circumferentially. The positioning cylinder 732 has a first stop groove 7321 and a second stop groove 7322 arranged alternately circumferentially. The distance between the bottom of the first stop groove 7321 and the bottom of the positioning cylinder 732 is smaller than the distance between the bottom of the second stop groove 7322 and the bottom of the positioning cylinder 732. One end of the elastic element 733 is fixedly connected to the fixed shell 71, and the other end is fixedly connected to the first rod body 721 to cause the first rod body 721 to drive the locking blocks 722 closer to the pressing rod 731 and the positioning cylinder 732. This gives valve 70 two positions, corresponding to the two states of the movable rod 72 blocking the water passage 205 and moving away from the water passage 205, respectively. When the abutment block 7312 pushes the locking block 722 out of the first position slot 7321, under the guidance of the locking surface 7221 and the push of the elastic element 733, releasing the pressing rod 731 will allow the locking block 722 to automatically rotate and enter the second position slot 7322, thus realizing the position switching.

[0058] Furthermore, in order to ensure a secure connection between the positioning cylinder 732 and the movable rod 72, in one embodiment provided in this application, the second stop groove 7322 has a first guide surface 73221, a stop surface 73222, and a second guide surface 73223 connected sequentially in the circumferential direction. The first guide surface 73221 is connected to the opening of the first stop groove 7321, and the second guide surface 73223 is connected to another adjacent first stop groove 7321. When the locking block 722 is located in the second stop groove 7322, the first guide surface 73221 is in contact with the locking surface 7221. To further facilitate the switching of the locking block 722 from the second stop groove 7322 to the first stop groove 7321, the second guide surface 73223 has the same inclination trend as the first guide surface 73221. That is, the second guide surface 73223 gradually approaches the bottom of the positioning cylinder 732 along the circumferential direction, and when the locking block 722 switches from the second stop groove 7322 to the first stop groove 7321, the locking surface 7221 of the locking block 722 fits against the second guide surface 73223. To achieve fully automatic rotation, the circumferential length of the locking surface 7221 is greater than the circumferential length of the first guide surface 73221. In this way, when the locking block 722 is engaged in the second stop groove 7322, a portion of the locking surface 7221 still exists within the circumferential range of the first stop groove 7321. When pressing continues, the abutment block 7312 can push the locking block 722 out of the second stop groove 7322 until the locking surface 7221 reaches the junction of the second guide surface 73223 and the stop surface 73222. Under the pushing action of the elastic element 733, the movable rod 72 is guided to rotate by the locking block 722 and re-enters the adjacent first stop groove 7321. Optionally, the abutment block 7312 has an abutment surface 73121 for engaging with the locking surface 7221, thus making the relative movement between the abutment block 7312 and the locking block 722 smoother. Preferably, the circumferential width of the locking block 722 is equal to the circumferential width of the first stop groove 7321, thus ensuring that there is no relative rotation between the pressing rod 731 and the positioning cylinder 732. It is understood that a matching guide rail structure can also be provided axially between the pressing rod 731 and the positioning cylinder 732 to ensure that the abutment block 7312 does not enter the second stop groove 7322.

[0059] This application also provides a steam oven, which includes an inner cavity body and an evaporation plate assembly as described above. The evaporation plate assembly is installed on the bottom wall of the inner cavity body. In actual use, the residual water in the evaporation plate can be reused under the triple filtration effect, avoiding the problem of limescale in the water tank, reducing water costs, and the press operation is simple and easy to understand, and easy to clean. It covers the user's needs for water conservation, cleaning, easy operation and less maintenance in the use of steam ovens.

[0060] Please refer to it again. Figure 1Optionally, in the embodiments provided in this application, the outer peripheral wall of the drain cylinder 20 is further provided with a thread 504 for engaging with the inner liner body, so that the drain cylinder 20 and the inner liner body are tightly assembled to prevent water leakage.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
