Description

Technical Field

[0001] The utility model relates to the technical field of steam ironing machines, in particular to an ironing device with a modular steam boiler. Background Art

[0002] At present, the ironing devices on the market are divided into two categories: hanging-bottle type and electric irons with steam boilers. For commercial use, the hanging-bottle type electric iron has a small steam output, low ironing efficiency and inconvenient water addition. The electric iron with a steam boiler has a large volume of the steam boiler, does not need to add water frequently, has a large steam output and high efficiency, and can better meet the use requirements of the commercial environment. For example, Chinese Patent CN209537891U discloses a steam electric iron, which includes a water supply water tank and an ironing assembly, and a pressure type boiler, which includes a boiler housing, an upper cover covering the boiler housing and at least one heating element. The heating element includes a heating part and a connector connected to an external power supply, and the heating element is hermetically connected to the boiler housing. The heating part is placed inside the boiler housing to directly heat the water in the boiler housing.

[0003] However, under the condition of absorbing the same amount of heat (the same heating power), when the steam boiler heats water to vaporize, a large-capacity steam boiler takes longer to reach the rated output pressure. The existing electric irons usually use a steam boiler with a capacity of 1 liter, and its wall thickness is basically between 1.5 mm and 2.0 mm. When the steam boiler with a wall thickness of 1.5 mm heats water to vaporize and the steam pressure exceeds 1.5 MPa, deformation appears near the air outlet at the top of the boiler, and a hill-shaped protrusion with a height of 3 mm and a diameter of 8 mm appears. The amount of energy in the steam boiler is determined by its volume. Under the same pressure condition, the larger the capacity of the steam boiler, the greater the internal energy storage, and the higher the safety risk.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an ironing device with a modular steam boiler that has a reasonable structure, fast steam response, safety and energy saving in view of the defects and deficiencies of the existing technology.

[0006] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0007] An ironing device of a modular steam boiler according to the present utility model includes a steam iron, a water tank and a steam module. The steam module includes a plurality of steam boilers, and a heating component is provided on the steam boiler. The water tank is respectively connected to the plurality of steam boilers through a water supply component; it further includes a multi-way pipe, the multi-way pipe is respectively connected to the plurality of steam boilers through pipelines, and the multi-way pipe is connected to the steam iron through an air delivery pipe. The present utility model has at least two steam boilers, and the plurality of steam boilers are respectively connected to the water supply component and the multi-way pipe. Each steam boiler operates simultaneously, which can shorten the vaporization time and accelerate the steam response speed; any steam boiler can operate independently to maintain the basic output of steam, saving energy and reducing consumption. Of course, in the case of damage to an individual steam boiler, it will not affect the use of the ironing device.

[0008] Furthermore, under the condition that the overall steam volume remains unchanged, multiple steam boilers with a small volume can output a higher pressure, enhance the penetration power of the steam, and the steam temperature is also higher, thereby effectively improving the ironing effect of the steam iron.

[0009] Even further, the energy contained in the steam boiler with a small volume is small, and the explosion-proof safety is improved.

[0010] According to the above solution, the water supply component includes a plurality of water pumps. The water inlet ends of the plurality of water pumps are respectively connected to the water tank through pipelines, and the water outlet ends of the plurality of water pumps are respectively connected to the corresponding steam boilers through pipelines. The water pumps supply water independently for the corresponding steam boilers, enabling the plurality of steam boilers to replenish water alternately without affecting the continuity of steam output. Specifically, since the plurality of steam boilers can work simultaneously or independently, the water volume in the steam boilers is small, and the heating and steam generation speeds are fast. When any steam boiler is short of water, the steam boiler disconnects the passage with the multi-way pipe and is replenished with water through the water pump. At this time, other steam boilers can operate normally, thus ensuring the continuity of steam output.

[0011] According to the above solution, a pressure protector is provided on the pipeline between the water supply component and the steam boiler. Specifically, the pressure protector is provided between the water outlet end of the water pump and the steam boiler. The pressure protector is used to relieve the pressure of the steam boiler. When the steam boiler is short of water, there is still a relatively high pressure inside, and the pressure protector needs to discharge the internal pressure before the water pump can replenish water to the steam boiler. It can be understood that the pressure protector can directly discharge the pressure to the water tank through the water pump pipeline.

[0012] According to the above solution, a first water level detector is provided on the steam boiler. When the water level in the steam boiler is too low, the first water level detector emits a signal, the heating component stops working, the pressure protector relieves the pressure of the steam boiler, and then the corresponding water pump starts to work to replenish water to the steam boiler.

[0013] According to the above solution, a second water level detector is provided on the water tank. The second water level detector is used to detect the water level in the water tank. When the water tank is short of water, the whole ironing device cannot be started, avoiding equipment failures.

[0014] According to the above solution, the heating component includes a heating plate. The heating plate is provided on the steam boiler, and an overheat protector is provided on the heating plate. A temperature controller is provided on the steam boiler. The temperature controller is used to detect the working temperature of the steam boiler. When the steam boiler overheats due to water shortage, the overheat protector can cut off the circuit of the heating plate to prevent dry burning.

[0015] According to the above solution, an upper steam valve is provided on the steam boiler. The upper steam valve is a solenoid valve, and the upper steam valve is connected to a multi-way pipe through a pipeline. The multi-way pipe serves as a steam concentration device for several steam boilers. When the steam boilers are working normally, steam can be output to the multi-way pipe through the upper steam valve. When any steam boiler stops or is replenished with water, the upper steam valve closes to prevent the pressure in the multi-way pipe from flowing back.

[0016] According to the above solution, a pressure sensor is provided on the steam boiler. The heating plate heats the water in the steam boiler, and the water boils and vaporizes, increasing the internal pressure of the steam boiler. When the steam iron is on standby, the pressure in the steam boiler and the multi-way pipe gradually rises. When the steam pressure rises to the set value, the pressure sensor closes the heating plate to prevent the internal pressure of the steam boiler from being too high. It can be understood that when the internal pressure of the steam boiler is too high, the pressure can also be relieved through a pressure protector.

[0017] According to the above solution, the present utility model further includes a controller. The controller is respectively connected to the multi-way pipe, the water pump, the pressure protector, the first water level detector, the second water level detector, the heating plate, the overheat protector, the temperature controller, the upper steam valve, and the pressure sensor through lines. The controller includes a PCBA circuit board. The PCBA circuit board integrates a control circuit and has a built-in program to control the operation of the ironing device.

[0018] Specifically, the ironing device can select a full-power mode or a low-power mode, and select the corresponding number of steam boilers and water supply components to work. Thus, when any steam boiler and heating plate fail, the ironing device can still work normally.

[0019] Furthermore, when the steam reserve pressure in the multi-way pipe is sufficient, the steam can be output from the multi-way pipe by turning on the switch on the steam iron, or the controller controls the heating plate to stop working and execute the standby program. When the first water level detector detects that the corresponding steam boiler is short of water, the controller closes the corresponding steam switch, opens the pressure protector to relieve the pressure, and then starts the water pump to replenish water to the steam boiler. When the second water level detector detects that the water tank is short of water, the controller turns off all heating plates and issues a water shortage signal to prompt the user to replenish water.

[0020] An ironing device with a modular steam boiler of the present utility model. A number of steam boilers are respectively connected to a water supply component and a multi-way pipe. When each steam boiler operates simultaneously, the vaporization time can be shortened and the steam generation response speed can be accelerated. When a single steam boiler operates, the basic output of steam can be maintained, achieving more energy conservation and consumption reduction. In particular, the volume of the steam boiler becomes smaller, and at the same steam volume, a higher pressure can be output, enhancing the penetration power of the steam, and the steam temperature is also higher, effectively improving the ironing effect of the steam iron.

[0025] The technical solution of the present utility model will be described below in conjunction with the drawings and embodiments.

[0026] As Figure 1-2 shown, an ironing device with a modular steam boiler of the present utility model includes a steam iron 1, a water tank 2 and a steam module. The steam module includes a number of steam boilers 3. A heating component is provided on the steam boiler 3. The water tank 2 is respectively connected to a number of steam boilers 3 through a water supply component. The present utility model further includes a multi-way pipe 11. The multi-way pipe 11 is respectively connected to a number of steam boilers 3 through pipelines, and the multi-way pipe 11 is connected to the steam iron 1 through an air delivery pipe. The present utility model has at least two steam boilers 3. A number of the steam boilers 3 are respectively connected to a water supply component and a multi-way pipe 11. When each steam boiler 3 operates simultaneously, the vaporization time can be shortened and the steam generation response speed can be accelerated. Any one of the steam boilers 3 can operate independently to maintain the basic output of steam, achieving energy conservation and consumption reduction. Of course, in the case where an individual steam boiler 3 is damaged, it will not affect the use of the ironing device.

[0027] Furthermore, under the condition of constant overall steam volume, multiple steam boilers 3 with a small volume can output a higher pressure, enhancing the penetration power of the steam, and the steam temperature is also higher, thereby effectively improving the ironing effect of the steam iron 1. Moreover, the energy contained in the steam boiler 3 with a small volume is smaller, and the explosion-proof safety is improved.

[0028] The specific principle is as follows:

[0029] Multiple steam boilers 3 are supplied with water in cooperation with independent water pumps 21, which reduces the volume of the steam boilers 3 and speeds up the steam generation speed. Under the condition of the same steam volume, the pressure of the steam boiler 3 with a smaller volume will be greater than that of the steam boiler 3 with a larger volume. In this way, the penetrating power of the released steam is stronger and the temperature of the steam is higher. When under the same pressure, the energy stored in the steam boiler 3 is calculated by the following formula:

[0030] E = V * ρ * (ig - if) * 103,

[0031] E: Energy

[0032] V: Volume

[0033] ρ: Density

[0034] ig: Enthalpy value of saturated steam (the greater the steam pressure, the smaller the enthalpy value)

[0035] if: Enthalpy value of saturated water (the greater the steam pressure, the greater the enthalpy value)

[0036] According to the above formula, when the steam pressures (total) of the steam boilers 3 are equal, the magnitude of the energy inside a single steam boiler 3 is determined by the volume of the steam boiler 3. Therefore, the energy inside multiple miniaturized steam boilers 3 will be greatly reduced during use; when the volumes of the steam boilers 3 are the same, the greater the steam pressure, the smaller the energy, which improves the explosion-proof ability of the steam boilers 3 and has higher safety.

[0037] The water supply assembly includes several water pumps 21. The water inlet ends of the several water pumps 21 are respectively connected to the water tank 2 through pipelines, and the water outlet ends of the several water pumps 21 are respectively connected to the corresponding steam boilers 3 through pipelines. The water pumps 21 supply water independently to the corresponding steam boilers 3, enabling the several steam boilers 3 to replenish water alternately without affecting the continuity of steam output. Specifically, since the several steam boilers 3 can work simultaneously or independently, the water volume inside the steam boilers 3 is small, and the heating and steam generation speeds are fast. When any steam boiler 3 is short of water, the steam boiler 3 disconnects the path with the multi-way pipe 11 and is replenished with water through the water pump 21. At this time, the other steam boilers 3 can operate normally, thus ensuring the continuity of steam output.

[0038] According to the above solution, a pressure protector 22 is provided on the pipeline between the water supply assembly and the steam boiler 3. Specifically, the pressure protector 22 is provided between the water outlet end of the water pump 21 and the steam boiler 3. The pressure protector 22 is used to relieve the pressure of the steam boiler 3. When the steam boiler 3 is short of water, there is still a relatively high pressure inside. The pressure protector 22 is required to discharge the internal pressure, and then the water pump 21 can supply water to the steam boiler 3. It can be understood that the pressure protector 22 can discharge the pressure to the water tank 2 via the pressure relief terminal 24.

[0039] A first water level detector 31 is provided on the steam boiler 3. When the water level in the steam boiler 3 is too low, the first water level detector 31 emits a signal, the heating component stops working, the pressure protector 22 relieves the pressure of the steam boiler 3, and then the corresponding water pump 21 starts to work to supply water to the steam boiler 3.

[0040] A second water level detector 23 is provided on the water tank 2. The second water level detector 23 is used to detect the water level in the water tank 2. When the water tank 2 is short of water, the ironing device as a whole cannot be started to avoid equipment failure.

[0041] The heating component includes a heating plate 32. The heating plate 32 is provided on the steam boiler 3. An overheat protector 33 is provided on the heating plate 32, and a temperature controller 34 is provided on the steam boiler 3. The temperature controller 34 is used to detect the working temperature of the steam boiler 3. When the steam boiler 3 overheats due to water shortage, the overheat protector 33 can cut off the circuit of the heating plate 32 to prevent dry burning.

[0042] An upper steam valve 35 is provided on the steam boiler 3. The upper steam valve 35 is preferably an electromagnetic valve. The upper steam valve 35 is connected to the multi-way pipe 11 through a pipeline. The multi-way pipe 11 serves as a steam concentration device generated by several steam boilers 3. When the steam boilers 3 are working normally, steam can be output to the multi-way pipe 11 through the upper steam valve 35. When any steam boiler 3 stops or is replenished with water, the upper steam valve 35 closes to prevent the pressure in the multi-way pipe 11 from flowing back.

[0043] Preferably, a pressure sensor 36 is provided on the steam boiler 3. The heating plate 32 heats the water in the steam boiler 3, and the water boils and vaporizes to increase the internal pressure of the steam boiler 3. When the steam iron 1 is on standby, the pressure in the steam boiler 3 and the multi-way pipe 11 gradually rises. When the steam pressure rises to the set value, the pressure sensor 36 closes the heating plate 32 to prevent the internal pressure of the steam boiler 3 from being too high. It can be understood that when the internal pressure of the steam boiler 3 is too high, the pressure can also be relieved through the pressure protector 22.

[0044] The utility model further includes a controller 4, and the controller 4 is respectively connected to a multi-way pipe 11, a water pump 21, a pressure protector 22, a first water level detector 31, a second water level detector 23, a heating plate 32, an overheat protector 33, a temperature controller 34, a steam valve 35 and a pressure sensor 36 through circuits. The controller 4 includes a PCBA circuit board, and a control circuit is integrated on the PCBA circuit board and has a built-in program to control the operation of the ironing device.

[0045] Specifically, the ironing device can select a full-power mode or a low-power mode, and select the corresponding number of steam boilers 3 and the water supply assembly to work. Thus, when any one of the steam boilers 3 and the heating plate 32 fails, the ironing device can still work normally.

[0046] Further, when the steam reserve pressure in the multi-way pipe 11 is sufficient, the steam output of the multi-way pipe 11 can be turned on through the switch on the steam iron 1, or the controller 4 controls the heating plate 32 to stop working and execute a standby program. When the first water level detector 31 detects that the corresponding steam boiler 3 is short of water, the controller 4 closes the corresponding steam switch, opens the pressure protector 22 to release pressure, and then starts the water pump 21 to replenish water to the steam boiler 3. When the second water level detector 23 detects that the water tank 2 is short of water, the controller 4 turns off all the heating plates 32 and sends a water shortage signal to prompt the user to replenish water.

[0047] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
