Description

Technical Field

[0001] The present invention relates to a heating device for generating steam, and more particularly, to a detachable plunger type steam generator and a steam pot. Background Art

[0002] The working mode of a traditional steam generator is that water body directly expands through a heating element to generate steam, and then the steam is quickly discharged outside the generator for use. In order to make the steam contain less water and have high quality, a plunger type steam generator with a secondary heating process is proposed. However, in the use process of such an integrated plunger type steam generator, due to the problem of the existence of metal ions, some water scale will be generated. And since this kind of generator has no drainage function, after being used for a period of time, a part of water scale will accumulate on the inner wall of the outer core and the inner core of the generator. If it is not cleaned in time, it will cause blockage after a long time, affecting the steam quality, and serious consequences will occur in severe cases. Summary of the Invention

[0003] The present invention aims to overcome at least one of the above-mentioned deficiencies of the prior art, and provides a detachable plunger type steam generator and a steam pot, which are used to solve the problem of water scale accumulation on the inner wall of the outer core and the inner core of the steam generator while providing high-quality steam.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A detachable plunger type steam generator includes a generator cavity and a detachable valve core assembly. The generator cavity includes a generator outer core located at the central axis position, a heating tube embedded in the generator cavity, and a water inlet pipe arranged outside the heating tube. The heating tube is spirally wound around the outside of the generator outer core, the water inlet pipe is correspondingly arranged outside the heating tube, the water inlet pipe includes an inlet end and an outlet end, the detachable valve core assembly includes a generator inner core, a valve core seat and a steam nozzle. The generator inner core can be detachably sleeved into the generator outer core. The generator inner core and the generator outer core jointly form a steam channel. The outlet end of the water inlet pipe is communicated with the air inlet end of the steam channel. The heating process in the generator cavity includes primary heating in the water inlet pipe and secondary heating in the steam channel, and finally forms steam that is ejected from the air outlet end of the steam channel through the steam nozzle.

[0006] The generator cavity can be a die-cast aluminum body, which serves both the functions of heat conduction and heat preservation. The heat required for the two heating processes is provided by the heating tubes. The water inlet pipe is located outside the heating tubes. When water is injected into the generator, due to the heat conduction of the generator cavity, the heating tubes have heated the water inlet pipe to a certain temperature. The liquid water flows in the water inlet pipe and is heated once to produce a high-temperature and high-pressure steam-water mixture. The steam-water mixture enters the steam channel and is heated a second time. The outer wall of the steam channel and the heating tubes are integrated by die-cast aluminum, enabling the steam channel to be directly heated by contact with the heating tubes, thereby forming completely stable steam, which then sprays out from the steam channel for use by external actuators such as steam pots. Compared with ordinary plunger steam generators, the detachable valve core assembly can be removed from the generator to clean the inner core and outer core of the generator, removing scale. Therefore, it will not reduce the efficiency of the steam generator due to scale accumulation over a long period of use, nor will it pose a danger due to severe fouling.

[0007] Further, the outer core of the generator is threadedly connected to the valve core seat. With the assistance of gaskets, sealing rings, etc., the threaded connection has good fastening and sealing effects, and is convenient for disassembly and assembly operations.

[0008] Further, there is a gap channel between the inner core and the outer core of the generator, and the gap channel communicates with the outlet end of the steam channel. When the steam-water mixture flows into the steam channel, the high-kinetic-energy steam directly brings water droplets into the inner core and the inner wall of the outer core. In this cavity, the water droplets enter the top of the inner core of the generator and then turn back, and then enter the gap channel between the inner and outer cores, with their movement directions changing multiple times. The purpose is to extend the vaporization time and the movement trajectory length of the steam inside the generator. After the steam is completely vaporized, it is discharged from the top. The steam treated in this way has a high dryness, low water content, better steam saturation, and higher overall steam quality.

[0009] Further, the heating tubes are in direct contact with the outer wall of the outer core of the generator. The heating tubes continuously provide heat, and the outer core of the generator in contact with them is heated, further vaporizing the steam-water mixture flowing through the gap channel between the inner and outer cores into completely steam, which is then stably output from the top of the outer core of the generator.

[0010] Further, the valve core seat includes a lateral air outlet hole, and the lateral air outlet hole is located above the top of the inner core of the generator. The valve core seat is used to transmit steam, and the lateral air outlet hole can change the movement direction of the steam, slowing down the movement speed of the high-pressure steam and making the output more stable.

[0011] A check steel ball is provided above the lateral air outlet hole. The function of the check steel ball is to make the steam valve a one-way valve, preventing the condensate water and steam-water mixture generated during the discharge of steam from flowing back.

[0012] Furthermore, the detachable plunger steam generator further comprises a detachable nozzle assembly. The lower part of the nozzle seat of the nozzle assembly is connected to the upper part of the steam nozzle, and the upper part of the nozzle seat is connected to an external execution system. The steam output does not pass through an intermediate pipeline, resulting in higher energy efficiency and higher energy utilization. The nozzle assembly is installed together with the cookware, and the detachable design enables the nozzle seat to be removed from the steam pot at any time.

[0013] Furthermore, the detachable plunger steam generator further comprises a water pump, which is connected to the inlet end of the water inlet pipe. The water pump stably pumps liquid water for the generator. The water pump is used to provide the power for water injection, and the inlet end of the water inlet pipe is located at the top of the plunger steam generator. The advantage of setting the water inlet at the top of the generator is that when the liquid water body is added to the plunger steam generator through the action of the water pump, water enters from the top. Under the action of gravity, the pressure of the water pump can be reduced, and due to the increase in the inner surface area of the pipeline affected by scale, the uniform distribution degree of scale generation can be increased, thereby delaying the time when the water inlet pipe is blocked by scale and ultimately extending the service life of the plunger steam generator.

[0014] Furthermore, the detachable plunger steam generator further comprises a steam adapter pipe, which connects the outlet end of the water inlet pipe and the lower part of the steam channel. The steam adapter pipe connects the water inlet pipe and the steam channel inlet, and is mainly used to transport the steam-water mixture after primary heating to the inner and outer cores for secondary heating.

[0015] Furthermore, the detachable plunger steam generator further includes a front-end element of the temperature control system, which is connected to the heating tube and is arranged outside the generator cavity. The front-end element of the temperature control system is connected to the heating tube and is used to control the temperature of the heating tube, making the heating tube stable at a high temperature and not easily damaged due to temperature runaway. At the same time, since the front-end element of the temperature control system is arranged outside the generator cavity, when the heating tube malfunctions, it can be observed and repaired in a timely manner.

[0016] A steam pot containing a detachable plunger steam generator further comprises a circuit assembly, a base, a steam cookware, a circuit board protection plate, a cooling fan, a temperature sensor, a pressure relief valve, and a water inlet joint. The steam cookware is connected above the base, the base is connected above the plunger steam generator, and the circuit assembly, the circuit board protection plate, the cooling fan, the temperature sensor, the pressure relief valve, and the water inlet joint are arranged at the lower end of the steam pot. The plunger steam generator generates steam for the steam cookware to use. After using for a period of time, the inner core of the steam generator can be taken out for descaling and maintenance.

[0017] The circuit components inside the steam pot of this technical solution are used to control the working process, working mode, etc. of the steam pot. The circuit components include an electronic control unit such as a circuit main board, a temperature control unit, a main power supply, a steam generator control unit, a water flow control unit, a control unit, a pressure relief unit, etc. A circuit board protection board is arranged between the steam generator and the circuit components for wet and dry separation, isolating the generator from the circuit components to protect each electronic control unit.

[0018] A cooling fan is arranged below the circuit components of the steam pot of this technical solution. Since the control element of the steam generator control unit is a thyristor, a large amount of heat will be generated during operation, and the cooling fan must be used to take away the heat in time so that the steam generator can work for a long time.

[0019] In order to enable the generator to be used normally and continuously generate high-quality steam, the steam pot of the present invention is also provided with a temperature sensor for monitoring the temperature change of the generator and timely adjusting the power of the heating tube and the water inflow; at the same time, a high-temperature snap-action switch is provided. When the temperature reaches a certain set value, the working power supply of the generator is cut off to protect other parts inside the machine body, and a high-temperature fuse is provided. When the front temperature control unit fails to control, the main power supply is cut off to protect the product.

[0020] The steam pot of this technical solution is also provided with a pressure relief valve. When the generator is blocked, the generator continuously generates steam, but when the outlet is blocked by scale, etc., the pressure of the generator will increase. When the pressure reaches the limit of the water inlet pipe, there will be a risk of pipe explosion. In order to avoid such risks, an automatic pressure relief unit is specially provided. When the pressure of the generator exceeds the set limit value, the pressure relief valve is automatically opened to discharge some steam, reducing the air pressure inside the generator to ensure the normal operation of the generator. At the same time, the pressure sensor detects and reports an error to protect the safety of the product.

[0021] All the electronic control units of this technical solution are installed in a plastic bottom shell to meet safety regulations and product manufacturability.

[0022] The steam pot described in the present invention is also provided with a water inlet joint at the bottom for water pump inlet, and a hidden power cord inlet is provided for easy embedded installation.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] (1) The detachable valve core assembly can be removed from the generator, and the inner core and outer core of the generator can be cleaned and maintained, with less water accumulation and scale, and the service life of the generator is longer;

[0025] (2) It can stably provide steam with high dryness, low water content and high overall quality;

[0026] (3) It is easy to control the high temperature of the heating tube;

[0027] (4) It has a simple structure. The steam is directly ejected from the steam port without passing through an intermediate pipeline, resulting in higher energy efficiency and a higher degree of energy utilization. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiment 1

[0036] As Figures 1 to 4 shown, it is a sectional view of the detachable plunger type steam generator of the present invention.

[0037] A detachable plunger steam generator 14 according to Embodiment 1 includes a generator cavity 1 and a detachable valve core assembly. The generator cavity 1 includes a generator outer core 6 located at the central axis position, a heating tube 8 embedded in the generator cavity 1, and a water inlet pipe 9 provided outside the heating tube 8. The heating tube 8 is spirally wound around the outside of the generator outer core 6, and the water inlet pipe 9 is correspondingly arranged outside the heating tube 8. The water inlet pipe 9 includes an inlet end and an outlet end. The detachable valve core assembly includes a generator inner core 5, a valve core seat 11, and a steam nozzle 15. The generator inner core 5 is detachably sleeved inside the generator outer core 6. The generator inner core 5 and the generator outer core 6 together form a steam channel 2. The outlet end of the water inlet pipe 9 is communicated with the air inlet end 3 of the steam channel 2. The heating process in the generator cavity 1 includes primary heating in the water inlet pipe 9 and secondary heating in the steam channel 2, and finally forms steam that is ejected from the air outlet end 4 of the steam channel 2 through the steam nozzle 15.

[0038] The generator cavity 1 of Embodiment 1 is a die-cast aluminum body, and the generator cavity 1 has the functions of heat conduction and heat preservation. The heat required for both times of heating is provided by the heating tube 8. The water inlet pipe 9 is located outside the heating tube 8. When water is injected into the generator, due to the heat conduction of the generator cavity 1, the heating tube 8 has heated the water inlet pipe 9 to a certain temperature. The liquid water flows in the water inlet pipe 9 and is heated for the first time to generate a high-temperature and high-pressure steam-water mixture. The steam-water mixture enters the steam channel 2 and is heated for the second time. The outer wall of the steam channel 2 and the heating tube 8 are integrally combined by die-cast aluminum, so that the steam channel 2 is directly heated in contact with the heating tube 8, thereby forming complete and stable steam, which is then ejected from the steam channel 2 for use by external actuators such as steam pots. Compared with ordinary plunger steam generators, the detachable valve core assembly can be removed from the generator to clean the generator inner core 5 and the generator outer core 6 to remove scale. Therefore, it will not reduce the efficiency of the steam generator due to scale accumulation after long-term use, nor will it be dangerous due to serious scale accumulation.

[0039] The generator outer core 6 and the valve core seat 11 are connected by threads. With the assistance of gaskets, sealing rings, etc., the threaded connection has good fastening and sealing effects and is convenient for disassembly and assembly operations.

[0040] There is a gap channel 7 between the generator inner core 5 and the generator outer core 6, and the gap channel 7 communicates with the air outlet end 4 of the steam channel 2. When the steam-water mixture flows to the steam channel 2, the high-kinetic-energy steam directly brings water droplets into the inner core and the inner wall of the outer core. In this cavity, the water droplets enter the top of the generator inner core 5 and then turn back, and then enter the gap channel 7 between the inner and outer cores. The movement direction changes multiple times. The purpose is to extend the vaporization time and the movement trajectory length of the steam inside the generator. After the steam is completely vaporized, it is discharged from the top. The steam processed in this way has a high dryness, low water content, better steam saturation, and higher overall steam quality.

[0041] The heating tube 8 is in direct contact with the outer wall of the generator outer core 6. The heating tube 8 continuously provides heat, and the generator outer core 6 in contact with it is heated, further vaporizing the steam-water mixture flowing through the gap channel 7 between the inner and outer cores into complete steam, and then stably outputting from the top of the generator outer core 6.

[0042] The valve core seat 11 includes a lateral air outlet 12, and the lateral air outlet 12 is located above the top of the generator inner core 5. The valve core seat 11 is used to transmit steam, and the lateral air outlet 12 can change the movement direction of the steam, slowing down the moving speed of the high-pressure steam and making the output more stable.

[0043] A check steel ball 13 is provided above the lateral air outlet 12. The function of the check steel ball 13 is to make the steam valve a one-way valve, so that the condensed water and steam-water mixture generated during the discharge of steam will not flow back.

[0044] The detachable plunger type steam generator 14 of this Embodiment 1 further includes a detachable nozzle assembly. The lower part of the nozzle seat 16 of the nozzle assembly is connected to the upper part of the steam nozzle 15, and the upper part of the nozzle seat 16 is connected to an external execution system. The steam output does not pass through an intermediate pipeline, with higher energy efficiency and higher energy utilization. The nozzle assembly is installed together with the cookware, and the detachable design enables the nozzle seat 16 to be removed from the steam pot at any time.

[0045] The detachable plunger type steam generator 14 of this Embodiment 1 further includes a steam transfer pipe 10. The steam transfer pipe 10 connects the outlet end of the water inlet pipe 9 and the lower part of the steam channel 2. The steam transfer pipe 10 connects the water inlet pipe 9 and the inlet of the steam channel 2, and is mainly used to transport the steam-water mixture after primary heating to the inner and outer cores for secondary heating.

[0046] The detachable plunger type steam generator 14 of this Embodiment 1 further includes a front-end element 17 of the temperature control system. The front-end element 17 of the temperature control system is connected to the heating tube 8, and the front-end element 17 of the temperature control system is arranged outside the generator cavity 1. The front-end element 17 of the temperature control system is connected to the heating tube 8 and is used to control the temperature of the heating tube 8, making the heating tube 8 stable at a high temperature and not easily damaged due to temperature out of control. At the same time, since the front-end element 17 of the temperature control system is arranged outside the generator cavity 1, when the heating tube 8 has an abnormality, it can be observed and repaired in time.

[0047] Embodiment 2

[0048] As Figure 5As shown in the figure, it is a schematic diagram of a steam pot containing a detachable plunger steam generator 14, which includes a circuit component, a plunger steam generator 14, a base 18, a steam pot 19, a circuit board protection plate 22, a cooling fan 23, a temperature sensor, a pressure relief valve 24, and a water inlet joint 26. The steam pot 19 is connected above the base 18, and the base 18 is connected above the plunger steam generator 14. The circuit component, the circuit board protection plate 22, the cooling fan 23, the temperature sensor, the pressure relief valve 24, and the water inlet joint 26 are arranged at the lower end of the steam pot. The plunger steam generator 14 generates steam for the steam pot 19 to use. The steam nozzle 15 leads the steam out from the inside of the plunger steam generator 14 and introduces it into the steam pot 19 through the nozzle seat 16 for cooking use. After using for a period of time, the inner core 5 of the steam generator can be taken out for cleaning, descaling, and maintenance.

[0049] The detachable plunger steam generator 14 further includes a water pump 20, and the water pump 20 is connected to the inlet end of the water inlet pipe 9. The water pump 20 stably pumps liquid water for the generator. The water pump 20 is used to provide the power for water injection, and the inlet end of the water inlet pipe 9 is located at the top of the plunger steam generator. The advantage of setting the water inlet at the top of the generator is that when the liquid water body is added to the plunger steam generator under the action of the water pump 20, water enters from the top. Under the action of gravity, the pressure of the water pump 20 can be reduced, and due to the increase in the inner surface area of the pipeline affected by scale, the uniform distribution degree of scale generation can be increased, thereby delaying the time when the water inlet pipe 9 is blocked by scale and ultimately extending the service life of the plunger steam generator.

[0050] The circuit component in the steam pot of this Embodiment 2 is used to control the working process, working mode, etc. of the steam pot. The circuit component includes an electronic control unit such as a circuit main board 21, a temperature control unit, a main power supply, a steam generator control unit, a water flow control unit, a control unit, and a pressure relief unit. A circuit board protection plate 22 is arranged between the steam generator and the circuit component for separating wet and dry, isolating the generator from the circuit component, and protecting each electronic control unit.

[0051] A cooling fan 23 is arranged below the circuit component of the steam pot in this Embodiment 2. Since the control element of the steam generator control unit is a thyristor, a large amount of heat will be generated during operation, and the cooling fan 23 must be used to take away the heat in time so that the steam generator can work for a long time.

[0052] In order to enable the generator to work normally and continuously generate high-quality steam, the steam pot of the present invention is also provided with a temperature sensor for monitoring the temperature change of the generator and timely adjusting the power of the heating tube 8 and the water inflow; at the same time, a high-temperature snap-action switch is provided. When the temperature reaches a certain set value, the working power supply of the generator is cut off to protect other parts in the machine body, and a high-temperature fuse is provided. When the temperature control unit in front fails to control, the main power supply is cut off, thereby protecting the product.

[0053] The steam pot of this Embodiment 2 is also provided with a pressure relief valve 24. When the generator is blocked, the generator continuously generates steam. However, if the outlet is blocked by scale or the like, the pressure of the generator will increase. When the pressure reaches the limit of the water inlet pipe 9, there will be a risk of pipe explosion. To avoid such risks, an automatic pressure relief unit is specifically provided. When the pressure of the generator exceeds the set limit value, the pressure relief valve 24 is automatically opened to discharge some steam, reducing the air pressure in the generator, ensuring the normal operation of the generator, and at the same time, the pressure sensor detects and reports an error, thereby protecting the safety of the product.

[0054] All the electronic control units of this Embodiment 2 are installed in the plastic bottom shell 25, meeting safety regulations and product manufacturability. The steam pot of the present invention is also provided with a water inlet joint 26 at the bottom for the water pump 20 to intake water, and a hidden power cord inlet is provided for easy embedded installation.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the technical solutions of the present invention, rather than limitations on the specific implementation manners of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the claims of the present invention shall be included within the protection scope of the claims of the present invention.
