[0002] In the winter in the north, when a large pot is used to boil water, steam or stew, the steam in the pot will overflow through the gap between the pot cover and the pot edge, and the overflowed steam will fill the kitchen space, not only affecting the line of sight, but also the steam will condense into water droplets on the surface of the wall, ceiling and cabinet, causing mildew on the wall and deformation of the cabinet. In the prior art, in order to solve this problem, a sealing pot ring that matches the pot cover is usually installed along the edge of the large pot, and a steam exhaust hole is opened on the side wall of the sealing pot ring, and a steam exhaust bellows is connected to the steam exhaust hole. The steam discharged from the large pot is introduced into the stove chamber or discharged outdoors by the steam exhaust bellows, so as to avoid steam from filling the kitchen. However, when using this sealing pot ring to handle steam, the height of the pot mouth will be artificially increased, which brings inconvenience to the user, and the discharged steam will increase the air humidity in the stove chamber after entering the stove chamber, affecting the burning effect of firewood, and discharging the steam outdoors is a waste of steam heat. Summary of the invention

[0003] The technical problem to be solved by the invention is to provide a large pot steam condensing device, which can fully utilize the heat of the steam in the pot while preventing the steam from spreading in the kitchen, and has the advantages of easy use and low production cost.

[0004] The technical solution adopted to solve the technical problem: a large pot steam condensation device includes a pot cover and a condensation cup. The pot cover is provided with a cup placing plane which cooperates with the bottom surface of the condensation cup so that the condensation cup can sit on the pot cover. A steam discharge hole is provided on the cup placing plane. The condensation cup includes a cup body and a condensation tube assembly installed in the cup body. A steam receiving short tube corresponding to the position and size of the steam discharge hole is provided at the bottom of the condensation cup. The short tube is inserted into the steam discharge hole to guide the steam output from the steam discharge hole into the condensation tube assembly.

[0005] As a further improvement of the present invention, a closing valve is arranged on the bottom surface of the pot cover, which can automatically open the steam discharge hole when the steam receiving short tube is inserted, and can automatically close the steam discharge hole when the steam receiving short tube is pulled out.

[0006] As a further improvement of the present invention: the condenser assembly includes a condenser lower fixing plate parallel to the bottom plane of the condenser cup, a condenser is mounted on the condenser lower fixing plate, and a steam inlet at the lower end of the condenser is connected to a steam receiving short tube.

[0007] As a further improvement of the present invention: the lower fixing plate of the condenser is sealed with the inner wall of the condenser cup and the outer wall of the condenser on all sides, and a distance is left between the lower fixing plate of the condenser and the bottom of the condenser cup, thereby forming a steam distribution chamber between the lower fixing plate of the condenser and the bottom of the condenser cup that connects the condenser and the steam receiving short tube.

[0008] As a further improvement of the present invention: the upper end of the steam receiving short tube is higher than the bottom of the condensation cup and lower than the lower port of the condensation tube, and a condensation water collecting groove is formed between the outer wall of the steam receiving tube and the bottom of the condensation cup and the inner wall of the condensation cup. The projection of the lower port of the condensation tube on the plane of the cup bottom is located in the condensation water collecting groove.

[0009] As a further improvement of the present invention, a condenser upper fixing plate is also installed at the upper end of the condenser.

[0010] As a further improvement of the present invention: a plurality of condensing tubes are arranged between the condensing tube upper fixing plate and the condensing tube lower fixing plate.

[0011] As a further improvement of the present invention: the steam discharge hole is provided with a sealing rubber ring which is in sealing cooperation with the outer wall of the steam receiving short pipe.

[0012] As a further improvement of the present invention: the closing valve includes a valve seat fixed on the pot cover, on which is mounted a flip valve plate that seals with the bottom surface of the sealing rubber ring, the flip valve plate is mounted on the valve seat via a pin shaft, and the closing valve also includes an automatic resetting device that keeps the flip valve plate in a normally closed state.

[0013] As a further improvement of the present invention: the automatic reset device is a reset spring installed on the pin shaft or a counterweight block connected to the flip valve plate.

[0014] The invention relates to a large pot steam condensing device, comprising a pot cover and a condensing cup. The pot cover is provided with a cup placing plane which matches with the bottom surface of the condensing cup so that the condensing cup can sit on the pot cover. A steam discharge hole is provided on the cup placing plane. The condensing cup comprises a cup body and a condensing tube assembly installed in the cup body. A technical scheme is provided at the bottom of the condensing cup, which is provided with a steam receiving short tube which corresponds to the position and size of the steam discharge hole and is inserted into the steam discharge hole to guide the steam output from the steam discharge hole into the condensing tube assembly. When in use, cold water is filled in the condensing cup, and the steam discharged from the steam discharge hole enters the condensing tube assembly through the steam receiving short tube. The steam is cooled into water when passing through the condensing tube, and only a small amount of steam is discharged. At the same time, the cold water in the condensing cup is heated to become hot water for washing hands and washing dishes. Therefore, the large pot steam condensing device of the invention can reduce the steam discharge amount, prevent steam from spreading in the kitchen, and can fully recover and utilize the energy of steam. No special sealing pot ring is required, and the height of the pot mouth will not be increased. It has the advantages of easy use and low production cost. Due to the technical feature that a closing valve is installed on the bottom surface of the pot cover, which can automatically open the steam discharge hole when the steam receiving short tube is inserted, and can automatically close the steam discharge hole when it is pulled out, it can prevent steam from being discharged outward from the steam discharge hole when there is no condensation cup seated on the pot cover. Due to the adoption of the condenser tube assembly including a condenser tube lower fixing plate parallel to the bottom plane of the condensation cup, a condenser tube is installed on the condenser tube lower fixing plate, and the steam inlet at the lower end of the condenser tube is connected with the steam receiving short tube, so that the condenser tube is better fixed in the condensation cup and the installation and fixing is more convenient. Due to the adoption of the technical feature that the condenser tube lower fixing plate is sealed with the inner wall of the condensation cup and the outer wall of the condenser tube around, a spacing is left between the condenser tube lower fixing plate and the bottom of the condensation cup, so that a steam distribution chamber connecting the condenser tube and the steam receiving short tube is formed between the condenser tube lower fixing plate and the bottom of the condensation cup, the steam introduced by the steam receiving short tube can be evenly distributed to multiple condensers. Due to the technical feature that the upper end of the steam receiving short tube is higher than the bottom of the condensation cup and lower than the lower end of the condensation tube, and a condensation water collection groove is formed between the outer wall of the steam receiving tube and the bottom and inner wall of the condensation cup, the condensation water formed in the condensation tube can be prevented from flowing back into the pot and dripping on the food. Due to the technical feature that a condensation tube upper fixing plate is also installed at the upper end of the condensation tube, the anti-seismic performance of the condensation tube is further improved. Due to the technical feature that multiple condensation tubes are arranged between the upper fixing plate of the condensation tube and the lower fixing plate of the condensation tube, the flow rate of steam in the condensation tube can be slowed down, the condensation effect of steam can be improved, and the overflow of steam can be reduced. Due to the technical feature that the steam discharge hole is equipped with a sealing rubber ring that seals with the outer wall of the steam receiving short tube, steam leakage between the steam discharge hole and the outer wall of the steam receiving short tube can be avoided.Since the closing valve includes a valve seat fixed on the pot cover, a flip valve plate sealingly matched with the bottom surface of the sealing rubber ring is installed on the valve seat, the flip valve plate is installed on the valve seat through a pin shaft, and the closing valve also includes a technical feature of an automatic reset device that puts the flip valve plate in a normally closed state, the structure of the closing valve is simpler and the effect is more reliable. Since the automatic reset device is a reset spring installed on the pin shaft or a counterweight connected to the flip valve plate, the large pot steam condensing device of the present invention is more convenient to assemble and has a lower production cost.

DETAILED DESCRIPTION

[0017] like Figure 1 As shown, the large pot steam condensation device of the present invention includes a pot cover 4 and a condensation cup 2. The pot cover is provided with a cup placing plane 6 which matches with the bottom surface of the condensation cup so that the condensation cup can sit on the pot cover. A steam discharge hole 5 is provided on the cup placing plane. A steam receiving short tube 3 corresponding to the position and size of the steam discharge hole is provided at the bottom of the condensation cup. The short tube is inserted into the steam discharge hole to guide the steam output from the steam discharge hole into the condensation tube assembly. A sealing rubber ring 11 is installed at the steam discharge hole to seal with the outer wall of the steam receiving short tube.

[0018] like Figure 2 As shown, a closing valve is installed on the bottom surface of the pot cover, which can automatically open the steam discharge hole when the steam receiving short tube is inserted, and can automatically close the steam discharge hole when it is pulled out. The closing valve includes a valve seat 13 fixed on the pot cover, and a flip valve plate 12 is installed on the valve seat to seal with the bottom surface of the sealing rubber ring. The flip valve plate is installed on the valve seat through a pin shaft 16, and the closing valve also includes an automatic reset device that puts the flip valve plate in a normally closed state.

[0019] Preferably, the automatic reset device is a reset spring mounted on the pin or a counterweight connected to the flip valve plate. Figure 3The automatic reset device in the embodiment is a counterweight block 17 connected to the flip valve plate. The counterweight block and the flip valve plate are respectively located on both sides of the flip valve plate mounting pin. In this way, the counterweight block can rely on its own gravity to automatically reset the flip valve plate after the steam receiving short pipe is pulled out, thereby closing the steam discharge hole.

[0020] like Figure 4 As shown, the condenser cup includes a cup body and a condenser tube assembly installed in the cup body, the condenser tube assembly includes an upper condenser tube fixing plate 8 and a lower condenser tube fixing plate 10 parallel to the bottom plane of the condenser cup, the upper condenser tube fixing plate is provided with a hole 7 for cold water to enter between the upper condenser tube fixing plate and the lower condenser tube fixing plate, a plurality of condenser tubes 9 are arranged between the upper condenser tube fixing plate and the lower condenser tube fixing plate, the condenser tube is a spiral condenser tube or a finned condenser tube, a condenser tube is installed on the lower condenser tube fixing plate, and the steam inlet at the lower end of the condenser tube is connected to the steam receiving short The tubes are connected, and the lower fixing plate of the condenser tube is sealed with the inner wall of the condenser cup and the outer wall of the condenser tube. There is a distance between the lower fixing plate of the condenser tube and the bottom of the condenser cup, so that a steam distribution chamber 14 connecting the condenser tube and the steam receiving short tube is formed between the lower fixing plate of the condenser tube and the bottom of the condenser cup. The upper end of the steam receiving short tube is higher than the bottom of the condenser cup and lower than the lower end of the condenser tube, and a condensate collecting groove is formed between the outer wall of the steam receiving tube and the bottom of the condenser cup and the inner wall of the condenser cup. The projection of the lower end of each condenser tube on the cup bottom plane is located in the condensate collecting groove 15.

[0021] Preferably, a condensate discharge hole is provided at the bottom of the condensate cup, and a sealing rubber plug is installed in the condensate discharge hole. After use, the sealing rubber plug is pulled out to drain the accumulated water in the condensate collection tank to prevent the growth of bacteria.

[0022] When the large pot steam condensing device of the present invention is used, cold water is first filled into the cold cup to immerse the condensing tube in the cold water, the condensing cup is seated on the cup placing plane of the pot cover, and the lower end of the steam receiving tube at the bottom of the condensing cup is inserted into the steam discharge hole of the pot cover. At this time, the lower end of the steam receiving tube pushes open the flip valve plate of the closing valve, so that the steam in the large pot enters the condensing tube through the steam distribution chamber, and the steam is condensed into water in the process of flowing upward in the condensing tube. The condensed water is discharged from the lower port of the condensing tube and drips into the condensing water collecting tank. Finally, only a very small amount of steam is discharged from the upper port of the condensing tube, so as to prevent the steam from spreading in the kitchen space. At the same time, the condensing cup filled with cold water is seated on the pot cover, and the weight of the cup body can also prevent the steam in the pot from lifting the pot cover and causing poor sealing between the pot cover and the pot mouth. The water heated by the steam in the condensing cup can be used for washing hands and washing dishes, etc., thereby improving the utilization rate of fuel.
