Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, specifically to a cooling and deodorizing water circulation device for a cooker. Background Technology

[0002] Cooking utensils typically produce fumes and smoke during use. For example, outdoor barbecue equipment produces fumes mixed with smoke and dust during the grilling process. The fumes are plentiful and have a strong smell. Moreover, the higher the temperature, the stronger the smell is perceived. If these fumes are directly released into the air, they will not only raise the temperature of the surrounding air but also pollute the surrounding air, affecting the breathing of nearby people. In other words, they will have a significant impact on the surrounding environment, which leads to greater restrictions on their use.

[0003] Currently, common methods for treating cooking fumes include a barbecue grill with fume purification function disclosed in patent CN214549003U. This grill has a heating element inside its main body and a connecting arm on one side of the top. A cover is mounted via the connecting arm, and the cover has an internal cavity containing a mesh layer, a steel wire layer on one side of the mesh layer, and an activated carbon layer on the other side. A ventilation fan is fixedly connected to one side of the cover. In use, the heating element heats the food on the grill plate. The resulting fumes rise and, with the help of the ventilation fan, enter the cavity inside the cover. The fumes then pass through the mesh layer, steel wire layer, and activated carbon layer in sequence. This physical purification process reduces harmful substances in the fumes and minimizes their harm to the human body. Although the above structure can treat flue gas, when only the mesh layer, steel wire layer and activated carbon layer are used for treatment, the flue gas is not fully treated when it passes through because these physical layers have large pores. A lot of oil fumes and odors will still not be treated. In addition, it cannot achieve cooling and has limited odor treatment capabilities, which still has a significant impact on the surrounding environment. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this invention aims to provide a cooling and deodorizing water circulation device for a cooker. The device comprises a water tank divided into a top air intake chamber and a bottom water storage chamber. The air intake chamber and water storage chamber are connected, and a water curtain forming component is installed between them. This water curtain forming component is connected to a water pump, allowing water pumped by the pump to form a complete water curtain at the connection between the air intake chamber and the water storage chamber. This ensures that when flue gas enters the water storage chamber from the air intake chamber, it passes through the water curtain, thus cooling and deodorizing the flue gas, improving the flue gas treatment effect, and reducing the impact on the surrounding environment.

[0005] The specific technical solution is as follows:

[0006] A cooling and deodorizing water circulation device for a cooker, characterized by the following features:

[0007] The water tank includes an air inlet chamber at the top and a water storage chamber at the bottom. The top of the air inlet chamber has an air inlet, and the bottom of the air inlet chamber and the top of the water storage chamber are connected to form a communication channel. The upper part of the water storage chamber has a smoke exhaust port.

[0008] A water curtain forming component includes a water supply pipe and a water collection plate. One end of the water supply pipe extends into the water storage chamber, and the other end of the water supply pipe is horizontally placed in the connecting channel. The water collection plate includes a water collection part and an extension part. The water collection part is located in the connecting channel and seals one side of the connecting channel. The water collection part has a water collection trough, which is horizontally placed in the connecting channel. The extension part is located on the side of the water collection trough near the area where flue gas flows, and the extension part is arranged inclined upwards.

[0009] The cooling and deodorizing water circulation device for a cooker described above has a water collection section and an extension section, both of which are plate-shaped structures and are integrated into one piece.

[0010] The cooling and deodorizing water circulation device for a cooker described above has a water supply pipe with several outlets along its length at one end, which is horizontally placed in the connecting channel, and the outlets are evenly distributed on the water supply pipe.

[0011] The aforementioned cooling and deodorizing water circulation device for a cooker includes a partition in the water storage chamber that divides the water storage chamber into a recovery chamber and an equipment chamber. The recovery chamber is located directly below the air inlet chamber, and the connecting channel is the connecting part between the recovery chamber and the air inlet chamber. The exhaust port is located at the top of the recovery chamber, and the equipment chamber is located beside the recovery chamber and is vertically offset from the air inlet chamber. One end of the water supply pipe extends into the water storage chamber and is installed into the equipment chamber, and a water pump is installed on the end of the water supply pipe installed into the equipment chamber.

[0012] The cooling and deodorizing water circulation device for a cooking appliance described above has several connecting holes at the bottom of the partition. When there is water in both the recovery chamber and the equipment chamber, the connecting holes are all located below the water surface.

[0013] The cooling and deodorizing water circulation device for a cooker mentioned above also includes a separating mesh plate. An insertion port is provided on the side wall of the recovery chamber corresponding to the exhaust port. The separating mesh plate is installed in the insertion port and covers the exhaust port.

[0014] In the above-mentioned cooling and deodorizing water circulation device for a cooker, a partition forms one side wall of the recycling chamber, and the inlet is located on the partition.

[0015] The cooling and deodorizing water circulation device for a cooker described above has an opening and closing door provided on the top and / or side of the equipment cavity.

[0016] The cooling and deodorizing water circulation device of the above-mentioned cookware has a drain outlet on the water tank, which is connected to the water storage chamber.

[0017] The positive effects of the above technical solution are:

[0018] The aforementioned cooling and deodorizing water circulation device for cooking appliances divides the water tank into an air intake chamber at the top and a water storage chamber at the bottom, which are interconnected to form a connecting channel. A water curtain forming component is installed within the connecting channel. One end of the water supply pipe of the water curtain forming component is connected to the water storage chamber, and the other end is horizontally placed within the connecting channel. Simultaneously, the water collection plate of the water curtain forming component includes a water collection part and an extension part horizontally placed within the connecting channel. The water flowing out of the water supply pipe is first collected through the water collection tank of the water collection part, and after the water level in the water collection tank reaches a preset height, it flows out through the extension part. This can form an uninterrupted water curtain that completely covers the flue gas circulation area within the connecting channel, and the formed water curtain has no blind spots. This allows the flue gas to pass through the water curtain completely when it enters the water storage chamber from the air intake chamber, thereby achieving cooling and deodorizing of the flue gas, improving the flue gas purification effect, and reducing the impact on the surrounding environment.

[0024] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 4The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0025] Figure 1 This is a structural diagram from one perspective of an embodiment of a cooling and deodorizing water circulation device for a cooker according to the present invention. Figure 2 This is a structural diagram from another perspective of an embodiment of a cooling and deodorizing water circulation device for a cooker according to the present invention; Figure 3 This is a cross-sectional view of a cooling and deodorizing water circulation device for a cooker according to this utility model. Figure 1 , Figure 2 as well as Figure 3 As shown, the cooling and deodorizing water circulation device for the cookware provided in this embodiment includes: a water tank 1 and a water curtain forming component 2.

[0026] Specifically, the water tank 1 includes an air inlet chamber 11 at the top and a water storage chamber 12 at the bottom, achieving an upper and lower layer distribution of the air inlet chamber 11 and the water storage chamber 12. At the same time, an air inlet 111 is provided at the top of the air inlet chamber 11, and the bottom of the air inlet chamber 11 and the top of the water storage chamber 12 are connected to form a connecting channel 13, so that the flue gas entering the air inlet chamber 11 from the air inlet 111 can subsequently enter the water storage chamber 12. In addition, a smoke exhaust port 121 is provided at the upper part of the water storage chamber 12, so that the flue gas that has been treated and enters the water storage chamber 12 can be drawn away from the smoke exhaust port 121, providing conditions for realizing water curtain filtration.

[0027] Figure 4 This is a structural diagram of the water curtain forming component of a cooling and deodorizing water circulation device for a cooker according to this utility model. Figures 1 to 4As shown, the water curtain forming component 2 includes a water supply pipe 21 and a water collection plate 22. One end of the water supply pipe 21 extends into the water storage chamber 12. When water is stored in the water storage chamber 12, the end of the water supply pipe 21 extends below the water surface, facilitating the extraction of water stored in the water storage chamber 12 and realizing water recycling, thus avoiding water waste. At the same time, the other end of the water supply pipe 21 is horizontally placed in the connecting channel 13, so that the water extracted by the water supply pipe 21 can be discharged into the connecting channel 13 through the other end of the water supply pipe 21, providing conditions for the subsequent formation of a complete water curtain in the connecting channel 13. The water collection plate 22 includes a water collection section 221 and an extension section 222. The water collection section 221 is disposed within the connecting channel 13 and seals one side of the connecting channel 13, so that when flue gas flows through the connecting channel 13, it can only flow through the side without the water collection section 221. This provides the condition for all the flue gas to pass through the water curtain, avoiding the problem of some flue gas not being treated due to leakage, and ensuring the effect of flue gas treatment. At the same time, it also provides space for the installation of the water collection plate 22 within the connecting channel 13. In addition, the water collection section 221 has a water collection tank 2211, through which water delivered from the water supply pipe 21 is collected first, providing a sufficient water source for the formation of the complete water curtain, so that the complete water curtain can be continuous and uninterrupted, ensuring the effect of flue gas treatment. Furthermore, the water collection trough 2211 is horizontally positioned within the connecting channel 13, ensuring that every area of ​​the connecting channel 13 used for flue gas flow has a corresponding section of the water collection trough 2211. This provides the conditions for achieving a complete water curtain that fully covers the flue gas flow area without any blind spots, ensuring complete flue gas treatment. The extension 222 is located on the side of the water collection trough 2211 near the flue gas flow area. The extension 222 is arranged at an upward angle, forming a water-retaining slope at the opening of the water collection trough 2211. This ensures that water must be collected to a predetermined level in the water collection trough 2211 before it overflows the extension 222 and flows into the flue gas flow area. The extension 222 also raises the height of the water flow, increasing its gravitational potential energy. As the water overflows and flows out from the extension 222, it forms a water curtain along a parabola. This water curtain provides a larger passage area for the flue gas in the vertical direction, resulting in a stronger and more efficient flue gas treatment capacity. Furthermore, the extension 222 is also horizontally positioned within the connecting channel 13, ensuring a uniform height throughout. This allows the water in the water collection tank 2211 to flow out through the extension 222 with a consistent water level, forming a continuous water curtain of a certain thickness. As the flue gas passes through the connecting channel 13, it is completely enveloped by the water curtain, which cools and deodorizes the gas, improving the flue gas treatment effect. It is worth noting that since the odor intensifies at higher flue gas temperatures, using a water curtain to cool the flue gas also enhances the deodorization effect, further improving the flue gas treatment capacity.

[0028] More specifically, both the water collection section 221 and the extension section 222 are plate-like structures, which can reduce space occupation while meeting usage requirements, and provide a larger covering and guiding area, thus providing conditions for the formation of a water curtain and complete treatment of flue gas. Preferably, the water collection section 221 and the extension section 222 are an integral structure, which can be formed by bending multiple times using bending equipment such as bending machines, making processing convenient, with higher structural strength and greater structural stability.

[0029] More specifically, the water supply pipe 21 is horizontally placed in the connecting channel 13, and a number of water outlets 211 are opened along its length. The water outlets 211 are evenly distributed on the water supply pipe 21, so that the water in the water supply pipe 21 can flow out through the water outlets 211 and enter the water collection tank 2211, providing a water source for the formation of the water curtain. In addition, the even distribution of the water outlets 211 along the length of the water supply pipe 21 makes the water replenishment points corresponding to the water collection tank 2211 more and more even, further improving the stability of the water surface in the water collection tank 2211 and reducing the flow of water in the water collection tank 2211. This makes the water curtain formed by the water in the water collection tank 2211 through the extension 222 more even and less prone to interruption, thus ensuring the treatment effect of the flue gas.

[0030] More specifically, a partition 122 is provided inside the water storage chamber 12, which divides the water storage chamber 12 into a recovery chamber 123 and an equipment chamber 124. The recovery chamber 123 is located directly below the air intake chamber 11. The connecting channel 13 is the connecting part between the recovery chamber 123 and the air intake chamber 11. The exhaust port 121 is located above the recovery chamber 123, so that the flue gas entering the air intake chamber 11 can enter the recovery chamber 123 through the connecting channel 13 and then be discharged through the exhaust port 121. At this time, after the water curtain is formed in the connecting channel 13, the flue gas needs to pass through the water curtain. The water curtain cools and deodorizes the flue gas, filters out dust, removes odors, and purifies the flue gas, reducing the impact on the surrounding environment. At this time, the equipment chamber 124 is located next to the recovery chamber 123 and is vertically offset from the air intake chamber 11, so that the equipment chamber 124 is not blocked by the air intake chamber 11. In addition, one end of the water supply pipe 21 extending into the water storage chamber 12 is installed into the equipment chamber 124, and a water pump 3 is installed on the end of the water supply pipe 21 installed in the equipment chamber 124. The water pump 3 supplies water to the water supply pipe 21. At the same time, the water pump 3 located in the equipment chamber 124 is also convenient for later maintenance and repair, and the structural design is more reasonable.

[0031] More specifically, the bottom of the partition 122 has several connecting holes 1221, allowing water in the recovery chamber 123 to flow from the connecting holes 1221 to the equipment chamber 124, where it is then drawn by the water pump 3 to meet the water recycling requirements. It is worth noting that when both the recovery chamber 123 and the equipment chamber 124 contain water, the connecting holes 1221 are all located below the water surface, preventing the leakage of flue gas entering the recovery chamber 123 through the connecting holes 1221, resulting in a more rational structural design.

[0032] More specifically, a separation mesh plate is also installed on the water tank 1. At this time, an inlet 1222 is opened on the side wall of the recovery chamber 123 corresponding to the exhaust port 121. The separation mesh plate is installed in the inlet 1222 and covers the exhaust port 121, so that the flue gas discharged from the exhaust port 121 will pass through the separation mesh plate. At this time, the separation mesh plate is a water-blocking and air-permeable structure. Since the flue gas will carry away water vapor when passing through the water curtain, if the purified flue gas is directly discharged from the exhaust port 121, it will not only lead to excessive water loss, but also cause water vapor to enter the subsequent flue gas treatment equipment, thereby affecting the operation of the subsequent flue gas treatment equipment. By setting a separation mesh plate at the exhaust port 121, the flue gas circulation needs can be met, and water can be blocked, thus better meeting the usage needs. It is worth noting that since there are a large number of water-blocking and breathable structural products on the market, including but not limited to existing polymer waterproof and breathable membranes made of polyethylene, polypropylene, and other materials through hot-pressing composite, which can meet the requirements of breathability and water blocking, their specific structures and material selections will not be elaborated here. In addition, to ensure installation stability and sealing performance, a support strip is provided on the inner wall of the recovery chamber 123 and at the edge of the exhaust port 121. The separation mesh plate is stably supported at the exhaust port 121 by the support conditions. Furthermore, a sealing strip is provided on the side edge of the separation mesh plate or the edge of the exhaust port 121, so that when the separation mesh plate is installed at the exhaust port 121, the sealing strip can achieve a seal and prevent the leakage of flue gas.

[0033] More specifically, the partition 122 forms one side wall of the recycling chamber 123, and the inlet 1222 is located on the partition 122, so that the inlet 1222 is located on the side closer to the equipment chamber 124, which makes it easier for users to disassemble and install the separation mesh plate from the equipment chamber 124, making the operation more convenient and the structural design more reasonable.

[0034] More specifically, the top and / or side of the equipment cavity 124 are equipped with opening and closing doors, allowing the equipment cavity 124 to be closed during normal operation, achieving isolation from the outside world and improving safety. When maintenance or repair of structures such as the water pump 3 is required, the opening and closing doors can be opened before operation, making the process more convenient.

[0035] More specifically, water tank 1 is equipped with a drain outlet that connects to the water storage chamber 12, allowing dirty water to drain out after a period of operation, facilitating the cleaning of water tank 1. It is worth noting that water tank 1 can also be equipped with a water inlet for replenishing water. Alternatively, water can be directly replenished from the equipment chamber 124, both options meeting water replenishment requirements.

[0036] The cooling and deodorizing water circulation device for the cooker provided in this embodiment includes a water tank 1 and a water curtain forming assembly 2. The water tank 1 is configured to include a top air intake chamber 11 and a bottom water storage tank 1, with the air intake chamber 11 and the water storage tank 1 connected to form a connecting channel 13. Simultaneously, the water curtain forming assembly 2, including a water supply pipe 21 and a water collecting plate 22, is installed within the connecting channel 13. One end of the water supply pipe 21 is connected to the water storage chamber 12, and the other end is horizontally placed within the connecting channel 13. The water collecting plate 22 is horizontally placed within the connecting channel 13. Located within the connecting channel 13 and below the water supply pipe 21, the water collecting plate 22 has a water collecting part 221 including a water collecting trough 2211 and an extension part 222 disposed on one side of the water collecting part 221. This allows the water flowing out of the water supply pipe 21 to first be collected through the water collecting trough 2211 and then flow out through the extension part 222 after the water level reaches a preset height, forming a continuous water curtain that completely covers the flue gas circulation area without any blind spots. This ensures that the flue gas can completely pass through the water curtain, resulting in better cooling and deodorizing effects and improved flue gas purification capabilities.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
