Technical Field

[0001] The utility model belongs to the technical field of product steam engines, and in particular relates to a self-cleaning steam engine. Background Art

[0002] A steam engine, also called a steam generator (commonly known as a boiler), is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See attached Figure 1 -Attached Figure 3 and attached Figure 7 -Attached Figure 8 A self-cleaning steam engine comprises a body 1, a heating element 2 and a water tank 3. The water tank 3 is installed in the body 1, and a water storage chamber 30 and a water inlet 301 are provided inside the water tank 3. An exhaust pipe 302 and a water outlet pipe 303 are installed on the side wall of the water storage chamber 30. The outlet of the exhaust pipe 302 is located above the liquid level, and the bottom wall of the water storage chamber 30 is inclined downward and extends to the outlet of the water outlet pipe 303. The heating element 2 is installed on the water tank 3 and is used to heat the water in the water storage chamber 30.

[0034] Specifically, when in use, water is injected into the water storage chamber 30 through the water inlet 301, and the water is heated to form steam after the heating element 2 is started. The steam is discharged through the exhaust pipe 302. The water supply of the water inlet 301 and the operation of the heating element 2 are synchronized to ensure that the water in the water storage chamber 30 always maintains a specific amount for heating.

[0035] When cleaning, first turn off the heating element 2 and then open the drain pipe to allow the residual water in the water storage chamber 30 to flow. Since the bottom wall of the water storage chamber 30 is inclined, the scale will follow the water and flow out of the drain pipe to the outside, thereby achieving the cleaning purpose; and in this process, cleaning liquid and clean water can be continuously injected into the water storage chamber 30 to better rinse and remove the scale.

[0036] In summary, the utility model designs the bottom wall of the water storage chamber 30 of the water tank 3 to be inclined, which can prevent scale accumulation and corrosion of the water tank 3, and the bottom wall of the water storage chamber 30 extends to the pipe mouth of the drain pipe, which can ensure that all the water in the water storage chamber 30 flows out through the drain pipe, avoiding the retention of water and the generation of odor. The above design enables the steam engine to have the function of self-cleaning scale, effectively improving the working efficiency and service life of the steam engine.

[0037] See attached Figure 4 -Attached Figure 6 The heating element 2 is of various types, for example, electric heating wires, electric furnace tubes, etc., which are not limited in the present invention. In order to facilitate control, the present invention also includes a control unit 4. The heating element 2 is an electric heating rod. The control unit 4 is installed in the body 1 and is electrically connected to the electric heating rod.

[0038] Specifically, when in use, the control unit 4 controls the start and stop of the electric heating rod, thereby heating and evaporating the water in the water storage chamber 30; and the control unit 4 is a control panel and other control structures, which belong to the prior art and are not elaborated in detail in the utility model.

[0039] See attached Figure 4 -Attached Figure 5A partition 11 is also provided in the body 1, and the partition 11 divides the interior of the body 1 into two to form two independent spaces for installing the water tank 3 and the control unit 4 respectively. This design makes the overall structure neat and convenient for the early assembly test and later disassembly and maintenance of the water tank 3 and the control unit 4.

[0040] See attached Figure 3 -Attached Figure 7 The utility model also includes a sensing unit 5 installed in the water storage chamber 30, the sensing unit 5 includes a water level sensing component 51 and a water temperature sensing component 52, and the control unit 4 is electrically connected to the water level sensing component 51 and the water temperature sensing component 52.

[0041] Specifically, during use, the water level sensor 51 is used to detect the liquid level of the water storage chamber 30. If the liquid level is detected to be higher than a specific value, the water supply is stopped to prevent the exhaust pipe 302 from being flooded due to the high liquid level. If the liquid level is detected to be lower than a specific value, the water supply is maintained to prevent the dry burning due to the low liquid level.

[0042] The water temperature sensor 52 is used to monitor the water temperature in the water storage chamber 30 to control the shutdown timing of the heating element 2. If the water temperature is low, the control unit 4 controls the heating element 2 to continue heating. If the water temperature is too high, the control unit 4 controls the heating element 2 to stop heating, so that the water temperature can maintain evaporation at a specific temperature and remind the staff to carry out maintenance in time. Therefore, the control unit 4, the water level sensor 51 and the water temperature sensor 52 are used together to effectively solve the common problems existing in the operation of the steam engine.

[0043] Among them, there are various types of water level sensors 51 and water temperature sensors 52. For ease of understanding, in this embodiment, the water level sensor 51 is a liquid level sensor; the water temperature sensor 52 is a temperature sensor, which is installed on the water tank and extends into the water storage chamber 30.

[0044] Furthermore, the water temperature sensing component 52 may also include a temperature measuring tube 520, which is installed in the water tank 3 and connected to the two side walls of the water storage chamber 30. Therefore, the design of the temperature measuring tube 520 can, on the one hand, cooperate with the temperature sensor to further monitor the water tank temperature, play the role of multi-stage monitoring of water temperature, and improve the safety of use. On the other hand, it can also play the role of supporting the water tank 3, thereby preventing the water tank 3 from being compressed and deformed.

[0045] See attached Figure 3 -Attached Figure 6 The utility model also includes a drain valve 6, which is installed on the water outlet pipe 303, and an actuator 60 is provided on the drain valve 6. The control unit 4 is electrically connected to the actuator 60 to control the opening and closing of the drain valve 6.

[0046] Specifically, during cleaning, a signal is sent to the actuator 60 through the control unit 4 to control the drain valve 6 to open, thereby discharging the water in the water storage chamber 30; after cleaning, a signal is sent to the actuator 60 through the control unit 4 to control the drain valve 6 to close, and water is injected into the water storage chamber 30 to continue working.

[0047] See attached Figure 3 -Attached Figure 6 During the working process, air pressure will be generated in the water tank 3. If the pressure is too high, it will cause the water tank 3 to rupture. For this reason, the utility model also includes a safety valve 7. An air pressure pipe 304 is also installed on the side wall of the water storage chamber 30. The air pressure pipe 304 connects the water storage chamber 30 and the outside world. The safety valve 7 is installed on the air pressure pipe 304.

[0048] Specifically, under normal circumstances, the safety valve 7 is in a closed state, and the air pressure inside the water tank 3 is stable; when the pressure inside the water tank 3 is too high, the safety valve 7 will open automatically, so that the air pressure pipe 304 connects the water storage chamber 30 and the outside to release pressure, ensuring that the air pressure inside and outside the water tank 3 is balanced.

[0049] Among them, the safety valve 7 is a physical switch, which will automatically open and close under certain circumstances. Since it is an existing product, its specific structure is not described in the utility model.

[0050] See attached Figure 3 The exhaust pipe 302, the air pressure pipe 304, and the water outlet pipe 303 are all designed as straight pipes, and they directly pass through the body 1 to the outside. This design can make the pipe body continuous and avoid water leakage due to the bending arrangement of the pipe body, thereby effectively preventing the aging of the pipe body, improving operational safety and extending the service life.

[0051] See attached Figure 3 and attached Figure 6 -Attached Figure 8 The water in the water storage chamber 30 is prone to splashing after being heated and boiled. If the water splashes into the exhaust pipe 302, it will affect the use. For this reason, in the utility model, a first baffle 31 is provided in the water tank 3. The first baffle 31 is installed on the side wall of the water storage chamber 30 and is located between the liquid surface and the pipe mouth of the exhaust pipe 302.

[0052] Specifically, the first baffle 31 can block the water and prevent the water from splashing into the exhaust pipe 302, thereby improving the operating stability of the steam engine; wherein, the first baffle 31 can be tilted downward, and this design can make the blocked water have a downward flow trend, making it easier for the water to fall back to its original place, thereby reducing the burden on the first baffle 31.

[0053] See attached Figure 3 -Attached Figure 6In order to facilitate the control of water supply timing, the utility model also includes a water inlet valve 8, which is installed in the body 1, and the water inlet valve 8 is connected to the outside and the water inlet 301 through a pipeline, and the control unit 4 is electrically connected to the water inlet valve 8.

[0054] Specifically, when in use, the pipeline placed outside is connected to the water supply equipment [not shown in the figure], and the water inlet valve 8 is controlled to open by the control unit 4, so that the water from the outside can be pumped into the water storage chamber 30 through the water supply equipment for heating; if there is too much water in the water storage chamber 30, the water inlet valve 8 is closed by the control unit 4 to stop the water supply.

[0055] Furthermore, the sensing unit 5 can be used in conjunction with the water inlet valve 8, so as to control the opening and closing timing of the water inlet valve 8 according to the liquid level and water temperature in the water storage chamber 30, thereby realizing automatic water supply and automatic water cut-off, and improving the automation level of the steam engine.

[0056] See attached Figure 6 -Attached Figure 7 Considering that the amount of water pumped by the water supply equipment is large, it is easy to impact the sensing unit 5 and the heating element 2 in the water storage chamber 30. For this reason, in the utility model, the water inlet 301 is arranged on the bottom wall of the water storage chamber 30, and a second baffle 32 is provided in the water tank 3. The second baffle 32 is installed on the bottom wall of the water storage chamber 30 and is located directly above the water inlet 301.

[0057] Specifically, when the water supply equipment pumps water into the water inlet 301, the second baffle 32 will block the water and allow the water to disperse into the water storage chamber 30. Therefore, the design of the second baffle 32 can slow down the speed at which the water enters the water storage chamber 30 and prevent the water from impacting the sensing unit 5 and the heating element 2 in the water storage chamber 30, thereby effectively improving the water supply stability and avoiding damage to the corresponding components.

[0058] See attached Figure 4 -Attached Figure 6 Considering that when cleaning the water tank 3, if only relying on the water injected from the water inlet 301 to rinse the walls of the water storage chamber 30, the cleaning may not be in place, and it is also difficult to prevent the cleaning liquid from entering the water inlet 301, for this reason, in the utility model, a cleaning port 305 connected to the outside is provided on the top wall of the water storage chamber 30, and a sleeve 10 connected to the cleaning port 305 is installed on the body 1, and a cover 100 is detachably installed on the sleeve 10.

[0059] Specifically, under normal circumstances, the cover 100 closes the sleeve 10 to prevent steam from overflowing; when cleaning, the cover 100 is removed, and water and cleaning liquid can be injected into the water storage chamber 30 through the sleeve 10 and the cleaning port 305 for flushing, effectively improving the cleaning efficiency and cleaning effect.

[0060] See attached Figure 3 -Attached Figure 7The utility model also includes an aromatherapy tank 9, and a carrier 33 is also provided in the water tank 3. The carrier 33 is installed on the top wall of the water storage cavity 30 and is located directly below the cleaning port 305; the aromatherapy tank 9 is provided with a accommodating cavity 90 for filling fragrances, and the accommodating cavity 90 is provided with a plurality of filter holes 900. The aromatherapy tank 9 can be detachably placed in the sleeve 10, and one end of the aromatherapy tank 9 passes through the cleaning port 305 and abuts against the carrier 33.

[0061] Specifically, when in use, lemons, fruits, Chinese herbs and other spices are placed into the accommodating cavity 90 of the aromatherapy jar 9 according to personal preference, and then the cover 100 is removed, and the aromatherapy jar 9 is placed in the sleeve 10 and abuts against the carrier 33; at this time, the steam in the water storage cavity 30 will pass through multiple filter holes 900 into the accommodating cavity 90 and contact the spices, thereby forming steam with a unique fragrance. This type of steam overflows to the outside through the sleeve 10 to achieve an aromatherapy effect, thereby improving the user experience.

[0062] See attached Figure 1 -Attached Figure 4 The machine body 1 is also provided with a hanging frame 12 and a base frame 13. The user can install the machine body 1 on a wall through the hanging frame 12, or can place the machine body 1 on a desktop through the base frame 13, thereby improving the installation convenience of the machine body 1.

[0063] It should also be noted that, although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
