Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a purification device and cooking equipment. Background Art

[0002] Cooking appliances such as steamers, ovens, and combi-steamers are becoming increasingly common, not only improving the taste of food but also making them easy to use. When these cooking appliances are in use, fumes and steam from the cooking cavity, after increasing the pressure within the cavity, are discharged into the kitchen through the cavity, resulting in a poor kitchen environment and causing discomfort to the user. Therefore, cooking appliances are often equipped with purification devices to address this issue.

[0003] A purification device typically consists of a water tank, a purification container, a water pump, and connecting pipes. The water tank and purification container are connected by connecting pipes, and the water pump is installed in the connecting pipes. An exhaust pipe is connected between the purification container and the cooking chamber. During operation, the water pump pumps water from the water tank into the purification container to a set height. The fumes and vapors generated by baking food in the cooking chamber enter the purification container through the exhaust pipe, are purified by the purification container, and are then discharged, absorbing and purifying the fumes and vapors.

[0004] In the prior art, the height of the water tank is generally not lower than the height of the purification container. When the water tank is filled with water, the connecting pipes and the water pump will be filled with water medium. The water pressure in the water tank is higher than the water pressure in the purification container. The connecting pipe forms a siphon tube, causing a siphon phenomenon between the water tank and the purification container. The water in the water tank flows into the purification container under the action of the siphon, causing the water level in the purification container to exceed the standard, and the water level detection component will alarm, causing the purification function of the purification container to fail.

[0005] Therefore, there is an urgent need for a new purification device and cooking equipment to solve the above problems existing in the prior art. Utility Model Content

[0019] The purification device further comprises a connecting pipeline, one end of which is connected to the liquid storage tank, the other end of which is connected to the liquid inlet pipe, and the liquid discharge pipe is connected to the purification container.

[0020] As an optional solution of the purification device provided by the present invention, the liquid inlet pipe includes a sealing pipe section and a guide pipe section inserted in the connecting pipeline, the guide pipe section is connected to the discharge pipe through the sealing pipe section, the sealing pipe section is in sealing contact with the inner wall of the connecting pipeline, the outer diameter of the guide pipe section is smaller than the outer diameter of the sealing pipe section, and the outer wall of the guide pipe section is provided with a stop barb.

[0021] As an optional solution of the purification device provided by the present invention, the purification container includes a top wall and side walls arranged around the top wall;

[0022] The anti-siphon member is installed on the top wall; alternatively, the anti-siphon member is installed on the side wall and extends upward.

By providing an anti-siphon cavity connected to the communicating cavity on the anti-siphon component, and making the highest position of the anti-siphon cavity higher than the highest liquid level of any of the liquid storage tank, the purification container and the communicating cavity, when the liquid in the liquid storage tank enters the purification container through the communicating cavity, the liquid level in the communicating cavity is always lower than the highest position of the anti-siphon cavity. Therefore, the liquid cannot always fill the entire inner cavity of the anti-siphon component during the liquid filling process, and there is always air in the inner cavity of the anti-siphon component, eliminating the possibility of the liquid channel between the liquid storage tank and the purification container forming a siphon channel, thereby preventing the generation of a siphon phenomenon between the liquid storage tank and the purification container, preventing the liquid in the liquid storage tank from flowing into the purification container under the siphon action, and preventing the liquid level in the purification container from exceeding the standard and causing the purification function of the purification container to fail.

[0049] In the embodiments of the present invention, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted.

[0050] like Figure 1 and Figure 2 Figure 1 is a schematic diagram of a conventional cooking device. The cooking device comprises a housing 100 and an inner container 200 mounted within the housing 100. The inner container 200 defines a cooking cavity. When the cooking device is in use, fumes or steam within the cooking cavity are discharged into the kitchen environment after the pressure within the cavity increases, resulting in an unpleasant kitchen environment and discomfort for the user. Therefore, cooking devices are typically equipped with a purification device to address this issue.

[0051] See also Figure 1 and Figure 2 The purification device typically includes a liquid storage tank 1 for storing liquid, a purification container 2, and a connecting pipe 4. The liquid storage tank 1 and purification container 2 are connected via the connecting pipe 4, and an exhaust pipe 5 is connected between the purification container 2 and the inner pot 200. During operation, the liquid in the liquid storage tank 1 is pumped into the purification container 2 to a set height. The fumes and vapors generated by baking food in the cooking cavity enter the purification container 2 through the exhaust pipe 5, are purified by the purification container 2, and are then discharged, achieving the purpose of absorbing and purifying the fumes and vapors.

[0052] In the above-mentioned cooking equipment, the height of the liquid storage tank 1 is generally not lower than the height of the purification container 2. When the liquid storage tank 1 is full of liquid, the connecting pipe 4 will be filled with liquid medium, and the hydraulic pressure of the liquid storage tank 1 is higher than the hydraulic pressure in the purification container 2. The connecting pipe 4 forms a siphon tube, causing a siphon phenomenon between the liquid storage tank 1 and the purification container 2. The liquid in the liquid storage tank 1 flows into the purification container 2 under the action of the siphon, causing the liquid level in the purification container 2 to exceed the standard, and the liquid level detection component will alarm, causing the purification function of the purification container 2 to fail.

[0053] To solve the above problems, Figure 3 As shown, this embodiment provides a new cooking device, including a body 100, an inner pot 200 and a purification device, the inner pot 200 and the purification device are both installed in the body 100, and the purification container 2 is connected to the inner pot 200. Figure 3 and Figure 4 The purification device includes a liquid storage tank 1, a purification container 2 and an anti-siphon component 3.

[0054] The purification container 2 is configured to purify gas exhausted from the inner pot 200 of the cooking device. The anti-siphon member 3 is provided with a connecting cavity 30 and an anti-siphon cavity 34, which are interconnected. The liquid storage tank 1 is connected to the purification container 2 via the connecting cavity 30. The highest level of the anti-siphon cavity 34 is higher than the highest liquid level of any of the liquid storage tank 1, the purification container 2, and the connecting cavity 30.

[0055] In the purification device provided in this embodiment, the liquid storage tank 1 is connected to the purification container 2 through the connecting cavity 30 of the anti-siphon member 3, so that the liquid in the liquid storage tank 1 can pass into the purification container 2 through the connecting cavity 30, and the liquid level in the purification container 2 reaches a set liquid level, ensuring that the purification container 2 can play a purification role to absorb and purify the oil smoke or steam discharged from the inner pot 200 of the cooking device. By providing an anti-siphon cavity 34 connected to the connecting cavity 30 on the anti-siphon member 3, and making the highest position of the anti-siphon cavity 34 higher than the highest liquid level of any of the liquid storage tank 1, the purification container 2 and the connecting cavity 30, when the liquid in the liquid storage tank 1 enters the purification container 2 through the connecting cavity 30, the liquid level in the connecting cavity 30 is always lower than the highest position of the anti-siphon cavity 34. Therefore, during the liquid filling process, the liquid can never fill the entire inner cavity of the anti-siphon member 3, and there is always air in the inner cavity of the anti-siphon member 3, eliminating the possibility of the liquid channel between the liquid storage tank 1 and the purification container 2 forming a siphon channel, thereby preventing the generation of a siphon phenomenon between the liquid storage tank 1 and the purification container 2, preventing the liquid in the liquid storage tank 1 from flowing into the purification container 2 under the siphon action, and preventing the liquid level in the purification container 2 from exceeding the standard and causing the purification function of the purification container 2 to fail.

[0056] Exemplarily, the liquid storage tank 1 is a water tank, and the liquid stored therein is water.

[0057] See also Figure 3 and Figure 4 The purification device further includes a connecting pipeline 4 and a first liquid extraction member 6 disposed on the connecting pipeline 4. The first liquid extraction member 6 is used to extract the liquid in the liquid storage tank 1 into the purification container 2 through the connecting pipeline 4. Specifically, the connecting pipeline 4 includes a first pipeline 41 and a second pipeline 42. The first pipeline 41 is connected between the liquid storage tank 1 and the liquid inlet of the first liquid extraction member 6, and the second pipeline 42 is connected between the liquid outlet of the first liquid extraction member 6 and the anti-siphon member 3.

[0058] Exemplarily, the first liquid-pumping component 6 is a water pump.

[0059] The purification device further includes a return line 8 and a second liquid extraction member 7 disposed on the return line 8. The second liquid extraction member 7 is used to extract the liquid in the purification container 2 back into the liquid storage tank 1 through the return line 8. Specifically, the return line 8 includes a third line and a fourth line. The third line is connected between the purification container 2 and the liquid inlet of the second liquid extraction member 7, and the fourth line is connected between the liquid outlet of the second liquid extraction member 7 and the liquid storage tank 1.

[0060] Exemplarily, the second liquid-pumping member 7 is a water pump.

[0061] See also Figure 4 and Figure 5The communication channel 30 includes a first channel 311 and a second channel 321. The second channel 321 is connected to the liquid storage tank 1, and the first channel 311 is connected to the purification container 2. The liquid storage tank 1 is connected to the purification container 2 through the second channel 321 and the first channel 311, respectively, to realize the transfer of liquid from the liquid storage tank 1 to the purification container 2.

[0062] See also Figure 5 , the highest position of the first cavity 311 is connected to the highest position of the second cavity 321, and the anti-siphon cavity 34 is connected to the connecting point of the first cavity 311 and the second cavity 321. That is, the anti-siphon cavity 34 is connected to the highest position of the first cavity 311 and the highest position of the second cavity 321, ensuring that the anti-siphon cavity 34 is higher than the highest position of either the first cavity 311 or the second cavity 321. When the first liquid extraction member 6 extracts liquid from the liquid storage tank 1 into the purification container 2, the liquid in the first cavity 311 will not rise to fill the anti-siphon cavity 34. There is always air in the anti-siphon cavity 34, preventing the anti-siphon member 3 and the connecting pipe 4 from forming a siphon channel. See Figure 4 Since the highest position of the second cavity 321 is higher than the highest liquid level of the liquid storage tank 1, when the first liquid extraction component 6 stops operating, according to the principle of the communicating vessel, the liquid level in the liquid storage tank 1 is flush with the liquid level in the second cavity 321, and this liquid level is lower than the highest position of the second cavity 321, thereby ensuring that when the first liquid extraction component 6 stops operating, the liquid in the second cavity 321 will not overflow into the first cavity 311, and will not flow into the purification container 2.

[0063] Furthermore, the cross-sectional area of ​​the first cavity 311 is greater than the cross-sectional area of ​​the second cavity 321 ; and / or the cross-sectional area of ​​the anti-siphon cavity 34 is greater than the cross-sectional area of ​​the second cavity 321 .

[0064] In some embodiments, the cross-sectional area of ​​the first lumen 311 is larger than that of the second lumen 321, while the cross-sectional area of ​​the anti-siphon lumen 34 is smaller than that of the second lumen 321. When liquid flows through the second lumen 321 into the first lumen 311, due to the larger cross-sectional area of ​​the first lumen 311, it is difficult for the liquid to fill the first lumen 311 and thus does not flow up into the anti-siphon lumen 34, resulting in air always being present in the anti-siphon lumen 34.

[0065] In some embodiments, the cross-sectional area of ​​the anti-siphon channel 34 is larger than that of the second channel 321, while the cross-sectional area of ​​the first channel 311 is smaller than that of the second channel 321. When liquid flows through the second channel 321 into the first channel 311, it can fill the first channel 311 and flow upward into the anti-siphon channel 34 above. However, due to the larger cross-sectional area of ​​the anti-siphon channel 34, the liquid can avoid filling the entire anti-siphon channel 34, ensuring that there is always air in the anti-siphon channel 34.

[0066] In this embodiment, see Figure 5 The cross-sectional area of ​​the first cavity 311 is the same as that of the anti-siphon cavity 34 and is larger than the cross-sectional area of ​​the second cavity 321, so that the liquid level in the first cavity 311 is always lower than the highest point of the anti-siphon cavity 34, thereby preventing the anti-siphon member 3 and the connecting pipe 4 from forming a siphon tube due to being filled with liquid medium.

[0067] Exemplarily, the cross-sectional area of ​​the first cavity 311 and the cross-sectional area of ​​the anti-siphon cavity 34 are more than twice the cross-sectional area of ​​the second cavity 321 , so as to ensure that there is always air in the anti-siphon cavity 34 .

[0068] Optionally, the port where the second lumen 321 communicates with the first lumen 311 is lower than the anti-siphon lumen 34. The port where the second lumen 321 communicates with the first lumen 311 is the liquid outlet of the second lumen 321. The liquid outlet of the second lumen 321 is lower than the anti-siphon lumen 34, thereby forming the anti-siphon lumen 34 above the first lumen 311 and the second lumen 321.

[0069] In this embodiment, the first lumen 311 is located above the purification container 2 and is connected to the interior of the purification container 2, so that the liquid in the first lumen 311 can completely flow into the purification container 2. When the first liquid extraction member 6 stops operating, due to the presence of the anti-siphon lumen 34, the liquid in the first lumen 311 can flow into the interior of the purification container 2 under the action of gravity. Furthermore, along the direction from the end of the first lumen 311 that connects with the second lumen 321 to the purification container 2, the first lumen 311 gradually lowers, ensuring that the liquid in the first lumen 311 can be completely drained. At this time, there is no liquid in the anti-siphon lumen 34 and the first lumen 311, effectively preventing the formation of a siphon between the liquid storage tank 1 and the purification container 2.

[0070] Illustratively, the first cavity 311 is vertically disposed above the purification container 2. Of course, the first cavity 311 can also be disposed at an acute angle to the purification container 2, as long as it can ensure that the liquid in the first cavity 311 can be completely drained under the action of gravity.

[0071] See also Figure 5 and Figure 6 The anti-siphon member 3 includes a drain pipe 31 and an inlet pipe 32 connected to the side wall 22 of the drain pipe 31. The drain pipe 31 and the inlet pipe 32 are arranged at an angle. The drain pipe 31 encloses a first cavity 311 and an anti-siphon cavity 34, while the inlet pipe 32 encloses a second cavity 321. The second pipeline 42 of the connecting pipeline 4 is connected to the inlet pipe 32, and the drain pipe 31 is connected to the purification container 2. The tubular anti-siphon member 3 is easy to manufacture and conveniently connects to the connecting pipeline 4 and the purification container 2.

[0072] Of course, in other embodiments, the anti-siphon member 3 may also be configured in other shapes, as long as the communicating cavity 30 and the anti-siphon cavity 34 can be machined.

[0073] Optionally, the liquid inlet pipe 32 is plugged into the second pipe 42 of the connecting pipe 4 to ensure the sealing of the connection. Figure 5 The liquid inlet pipe 32 includes a sealing pipe section 322 and a guide pipe section 323 inserted into the connecting pipe 4. The guide pipe section 323 is connected to the liquid discharge pipe 31 through the sealing pipe section 322. The sealing pipe section 322 is in sealing contact with the inner wall of the connecting pipe 4. The outer diameter of the guide pipe section 323 is smaller than that of the sealing pipe section 322. The outer wall of the guide pipe section 323 is provided with a retaining barb 3231.

[0074] The outer diameter of the sealing tube section 322 is substantially equal to the inner diameter of the second pipeline 42. Since the outer diameter of the guide tube section 323 is smaller than that of the sealing tube section 322, the liquid inlet tube 32 can be smoothly guided into the second pipeline 42, making the insertion operation more convenient. The retaining barbs 3231 on the outer wall of the guide tube section 323 engage the inner wall of the second pipeline 42 to prevent the liquid inlet tube 32 from falling out of the second pipeline 42. When the liquid inlet tube 32 and the second pipeline 42 are connected, the sealing tube section 322 forms a sealed contact with the inner wall of the second pipeline 42, preventing leakage.

[0075] In this embodiment, the liquid inlet pipe 32 gradually tilts upwards in a direction close to the liquid discharge pipe 31 .

[0076] See also Figure 6 The purification container 2 includes a top wall 21 and sidewalls 22 surrounding the top wall 21. In some embodiments, the anti-siphon member 3 is mounted on the top wall 21 of the purification container 2, thereby ensuring that the anti-siphon member 3 is installed at a higher position. Once installed, the inner cavity of the anti-siphon member 3 is higher than the maximum liquid level in the purification container 2. When the maximum liquid level in the liquid storage tank 1 is higher than the maximum liquid level in the purification container 2, it is sufficient to ensure that the highest position of the anti-siphon channel 34 is higher than the maximum liquid level in the liquid storage tank 1, effectively reducing the length of the anti-siphon member 3.

[0077] In other embodiments, the anti-siphon member 3 may also be installed on the side wall 22 of the purification container 2 and extend upward so that the highest point of the anti-siphon channel 34 in the installed anti-siphon member 3 is higher than the highest liquid level of either the liquid storage tank 1 or the purification container 2.

[0078] See also Figure 3 and Figure 6The purification device also includes an air outlet pipe 5. The purification container 2 is provided with an air inlet. One end of the air outlet pipe 5 is configured to communicate with the inner pot 200 of the cooking device, and the other end is connected to the inner cavity of the purification container 2 through the air inlet, so that the gas output from the inner pot 200 can enter the purification container 2 through the air outlet pipe 5 and be purified. The anti-siphon member 3 is installed on the purification container 2, and the liquid storage tank 1 and the air outlet pipe 5 are respectively located on different sides of the anti-siphon member 3, so that the layout of the purification device is more reasonable and compact. Figure 1 and Figure 2 As shown, in the existing cooking equipment, the liquid storage tank 1 and the purification container 2 are arranged in the left-right direction, and the air outlet pipe 5 starts from the air inlet on the purification container 2, gradually extends away from the liquid storage tank 1, and bends downward to communicate with the inner pot 200. Figure 1 and Figure 2 When making improvements to the cooking device shown, the anti-siphon member 3 can be installed on the side of the air outlet pipe 5 close to the liquid storage tank 1, so that the length of the connecting pipe 4 between the liquid storage tank 1 and the purification container 2 can be shortened as much as possible, saving materials and layout space.

[0079] See also Figure 3 The purification container 2 is also connected to an exhaust pipe 10, through which the purified gas is discharged from the purification container 2. Furthermore, a heat dissipation duct 400 and a heat dissipation fan 300 are provided on the top wall 21 of the inner container 200, facing the air inlet of the heat dissipation duct 400. The airflow generated by the heat dissipation fan 300 is blown into the heat dissipation duct 400. The end of the exhaust pipe 10 away from the purification container 2 extends into the heat dissipation duct 400, allowing the purified gas to be discharged from the cooking device along with the airflow within the heat dissipation duct 400.

[0080] See also Figure 3 The purification container 2 is further provided with a liquid level detection member 9 for detecting the liquid level in the purification container 2. The liquid level detection member 9 exemplarily includes a liquid level sensor.

[0081] See also Figure 3 The cooking device also includes a heating tube 600, which is used to heat the food in the inner pot 200 to achieve cooking methods such as steaming and baking.

[0082] See also Figure 3 A control panel 500 is also provided on the top of the inner pot 200.
