[0002] At present, some electric steamer products on the market have added a wastewater tank on the basis of the original water tank to store wastewater generated during the cooking process in order to facilitate user cleaning and maintenance. However, in actual application, the problem of wastewater tank failure often occurs. The main reason is that the wastewater generated during the cooking process contains substances such as grease and food residues. When the above substances adhere to the indicator device used to indicate the water level in the wastewater tank, the movable parts of the indicator device are bonded to the surrounding structure, and cannot move up and down with the change of the water level in the water tank. At this time, the sensor on the outside of the water tank will not be able to determine the volume of wastewater in the water tank according to the height change of the indicator device. As a result, when the wastewater in the wastewater tank reaches the high water level, it cannot remind the user to clean it, and wastewater continues to be injected into the wastewater tank during work, and eventually the wastewater overflows.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example

[0029] according to Figures 1 to 6 The wastewater tank for the steam cooking device shown comprises a tank body 1 and an oil-water separation module 6 connected to the tank body 1. The oil-water separation module 6 separates the tank body 1 into a sedimentation area 5 and a wastewater area 2 for receiving wastewater generated by the steam cooking device. A float 3 for monitoring the water level is provided in the wastewater area 2. The oil-water separation module 6 comprises a plurality of filtering units for separating grease step by step.

[0030] The filter units are connected in series, and the filter units include external units located at both ends of the separation module and a connecting unit located between the external units. A connecting port 9 is provided at one end of the external unit along the vertical direction, and a connecting port 9 is provided at both ends of the filter unit along the vertical direction. Two adjacent filter units are connected through the connecting port 9 at the same end of the two units. The external unit is provided with an external interface for exchanging wastewater with the outside world, and the external interface is located in the middle of the external unit.

[0031] A grease absorbing material 12 is provided at the communication port 9, and the grease absorbing material 12 is grease absorbing cotton.

[0032] The wastewater tank is used to store wastewater generated by steam cooking equipment such as the electric steamer 16 during the cooking process. In order to timely feedback the amount of wastewater in the wastewater tank for timely cleaning, an indicator device that can be used to indicate the water level is now set in the wastewater tank to reflect the remaining volume of the wastewater tank at this time. Grease and food residues in the wastewater often adhere to the indicator device and other structures, causing the indicator device to be unable to timely reflect the height of the water level rise, affecting the accuracy of the indication. The function of the oil-water separation module 6 in this solution is to filter out food residues and grease in the wastewater to prevent grease, food residues, etc. in the wastewater from affecting the accuracy of the indicator device. The filter units are connected through the connecting port 9, and the two connecting ports 9 on the same filter unit are respectively located at the two ends of the filter unit in the vertical direction, and are divided into two types of connecting ports 9, high and low. Through the connection of the same type of connecting ports 9 between adjacent filter units, a connecting vessel principle structure is formed between the two filter units connected through the connecting port 9 at the lower end. Since grease floats on the water surface, when wastewater flows from one filter unit to another, since the connecting port 9 here is located at the lowest point under the water surface, part of the grease is left in the previous filter unit, and part of the grease flows to the next filter unit with the wastewater, achieving the effect of filtering out part of the grease. When two adjacent filter units are connected through the connecting port 9 at the high end, the water level of the wastewater needs to rise to the highest end of the filter unit before entering the next filter unit through the connecting port 9. In the process of filling the filter unit with wastewater, the food residue in the wastewater is deposited at the bottom of the filter unit, achieving the purpose of filtering out part of the food residue.

[0033] The purpose of the grease adsorbing material 12 is to absorb and collect the grease at the connecting port 9. Since the grease is not easy to collect, the grease adsorbing material 12 is used to centrally process the grease for later cleaning.

[0034] In an optional embodiment, the number of the filter units is three, and the three filter units include two external units and one connecting unit. The number of the filter units is determined according to the water flow in the wastewater tank. Since the external unit and the connecting unit are also connected through the connecting port 9, the wastewater can be effectively filtered twice in the process of passing through one external unit, entering the connecting unit, and then entering another external unit.

[0035] In an optional embodiment, the oil-water separation module 6 includes an outer frame 7 and two baffles 8 located in the outer frame 7. The filter unit is formed by the outer frame 7 and the baffles 8. Two external interfaces are respectively located at the two ends of the outer frame 7. One end of the baffle 8 is fixedly connected to the inner wall of the outer frame 7, and the other end surface is spaced between the inner wall of the outer frame 7 to form a connecting port 9. The two connecting ports 9 are respectively located at the two ends of the outer frame 7 along the vertical direction. The oil-water separation module 6 is formed by the plate parts. By arranging a plurality of baffles 8 in the outer frame 7 to form a plurality of connected cavities, the cavities are used as filter units and meet the functional requirements of the filter units, which greatly simplifies the structure and reduces the overall size of the oil-water separation module 6. The external interface is formed on the plate parts of the outer frame 7. The connecting port 9 is formed by the space between the end of the baffle 8 and the inner wall of the outer frame 7, which simplifies the structure of the external interface and the connecting port.

[0036] In an optional embodiment, the grease absorption material 12 is grease absorption cotton, and the grease absorption material 12 is located at the connecting port 9. The grease absorption cotton is lipophilic and can absorb grease dozens of times its own weight. By selecting the type of grease absorption cotton, it can be made hydrophobic to facilitate cleaning and replacement. At the same time, the grease absorption cotton is a flexible material and can be filled according to different space sizes and shapes.

[0037] In an optional embodiment, the electric steamer 16 further comprises a housing 1, a water inlet pipe 4 for conveying wastewater to be filtered, and a float 3 for monitoring the water level. The housing 1 is used to contain wastewater to be filtered and filtered, and has an assembly structure of the oil-water separation module 6 to facilitate the installation and positioning of the oil-water separation module 6. The float 3 can float on the water surface. When the water surface rises, the float 3 can be raised in the housing 1 accordingly, so as to indicate the water level and reflect the remaining capacity of the electric steamer 16.

[0038] In an optional embodiment, a water inlet pipe 4 for conveying wastewater to be filtered is provided above the box body 1, and a water baffle 15 is provided at the port of the water inlet pipe 4. The water baffle 15 guides the pumped wastewater into the box body 1, absorbs the impact force of the wastewater, reduces the flow rate of the wastewater, reduces the stirring effect of the flowing liquid on the wastewater in the box body 1, and facilitates the sedimentation of the wastewater.

[0039] In an optional embodiment, the housing 1 includes a sedimentation area 5, a wastewater area 2, and a separation area. The separation area is located between the sedimentation area 5 and the wastewater area 2. The inner wall of the housing 1 located in the separation area is provided with a card slot 14 for fixing the oil-water separation module 6. The oil-water separation module 6 is attached to the inner wall of the housing 1 at a corresponding position. The wastewater is statically layered in the sedimentation area 5, and the upper layer of wastewater enters the oil-water separation module 6. The wastewater in the wastewater area 2 is filtered wastewater. The oil-water separation module 6 is plug-in-connected to the housing 1 through the card slot 14 to facilitate the disassembly and assembly of the oil-water separation module 6 when cleaning.

[0040] In an optional implementation scheme, a float bracket 13 is provided at a corresponding position of the wastewater area 2 , and the float 3 is slidably connected to the box body 1 through the float bracket 13 .

[0041] In an optional embodiment, the two external interfaces are respectively a water inlet 10 and a water outlet 11, and a connecting port 9 near the water inlet 10 is higher in vertical height than another connecting port 9 near the water outlet 11. The outer frame 7 plate below the water inlet 10 and the box body 1 enclose a sedimentation area 5. When the height of the wastewater exceeds the height of the outer frame 7 plate below the water inlet 10, the plate separates the grease on the surface of the sedimentation area 5 into two parts, one part is located in the external unit inside the oil-water separation module 6, and the other part is located in the sedimentation area 5. The liquid level continues to increase. Due to the obstruction of the outer frame 7 plate above the water inlet 10, the grease in the sedimentation area 5 rises to the upper layer of the liquid and cannot enter the oil-water separation module 6. When the liquid level in the external unit rises to the connecting port 9 close to the upper end, the grease on the upper layer of the liquid first contacts the grease adsorption cotton. , the grease is absorbed, and the wastewater flows into the connected unit through the connecting port 9. At the bottom of the connected unit, there are also grease absorption cotton and a connecting port 9 connected to the external unit corresponding to the water outlet 11. A small amount of grease that has not been isolated and absorbed before is filtered and absorbed again at this position. The liquid in the sedimentation area 5 continuously flows to the connected unit through the connecting port 9 at the upper end. The liquid level in the space A begins to rise. When the liquid level exceeds the lower edge of the baffle 8 corresponding to the bottom connecting port 9, the baffle 8 here forms a barrier to prevent the grease in the connected unit from entering the external unit corresponding to the water outlet 11. When the liquid level in this external unit exceeds the height of the outer frame 7 plate below the water outlet 11, the wastewater reaches the wastewater area 2 of the box body 1. When the liquid level in the wastewater area 2 submerges the lower edge of the outer frame 7 plate above the water outlet 11, the outer frame 7 plate above the water outlet 11 forms a barrier to prevent the grease in the external unit corresponding to the water outlet 11 from entering the wastewater area 2.

[0042] In an optional embodiment, the two baffles 8 are vertically arranged, the two baffles 8 are parallel to each other, and each part of the outer frame 7 and the baffles 8 are parallel or perpendicular to each other.

[0043] like Figure 4 , Figure 5As shown, an electric steamer is provided, which is provided with a waste water tank for steam cooking equipment in the above embodiment, and the electric steamer includes a water accumulation part located at the bottom of the inner pot, and the water accumulation part is connected to the sedimentation area 5 of the above waste water tank through a pipeline, wherein a heating element for heating the water accumulation part is arranged below the water accumulation part, and the clean water tank of the electric steamer is connected to the water accumulation area through a pipeline, so that the water accumulation part and the heating element form a heating plate 17 to heat the water therein to generate steam. More specifically, the water inlet pipe 4 is connected to the water outlet hole 18 below the water accumulation part of the heating plate 17, and a waste water pump 19 is provided on the water inlet pipe 4. When the cooking work of the electric steamer 16 is finished, the waste water pump 19 pumps the residual water in the heating plate 17 and the grease, food residues, etc. in the water into the waste water tank through the water inlet pipe 4.
