[0002] In order to increase the steam volume and solve the problem of water leakage in the ironing head, existing ironing machines are usually equipped with heating components on the main unit and the ironing head respectively to obtain a large amount of steam or a high steam temperature. However, this easily causes the steam temperature to fluctuate, making it difficult to control it in a stable range, resulting in uneven ironing effect. Summary of the invention

[0003] Based on this, it is necessary to provide a steam generating device and a control method thereof, and an ironing machine to address the problem that the steam temperature of the existing ironing machines described above is high or low and difficult to control because the heating components are respectively provided on the main unit and the ironing head.

[0004] A steam generating device, comprising:

[0005] An ironing head and a host for placing the ironing head;

[0007] The number of the temperature sensors is at least two, and at least two of the temperature sensors are spaced apart on the second reheating component and are used to detect the temperature at both ends of the steam channel and feed back to the second reheating component and / or the first reheating component.

[0008] The steam generating device disclosed in the first aspect of the present application is characterized in that a first heating component and a second heating component are respectively provided on the main unit and the ironing head. First, the liquid to be heated in the water tank is transported to the first heating component for heating to obtain water-containing steam with a certain temperature, and then the water-containing steam is transported to the steam channel in the second heating component for secondary heating to obtain water-free steam. Finally, no less than two temperature sensors are arranged on the second heating component. Preferably, the number of the temperature sensors is two, and the two temperature sensors respectively measure the temperature values ​​at both ends of the steam channel, and control the output power of the second heating component according to the measured temperature values ​​to ensure that the temperature value measured by the temperature sensor at the exhaust port adjacent to the steam channel is controlled within a threshold range. The steam generating device of the above structure reduces the difficulty of temperature control of the second heating component by heating the liquid to be heated in the first heating component to a certain temperature and then transporting it to the second heating component. Then, by adopting two-point temperature detection of the temperature changes at both ends of the steam channel, the heating power of the second heating component and / or the first heating component can be adjusted in time, so that the steam temperature output by the steam channel is accurately controlled within the threshold range.

[0009] In one embodiment, the main unit further includes a water pump and a water tank, and the first heating component is connected to the water tank through the water pump.

[0010] The steam generating device in the above embodiment further defines that the main unit also includes a water pump and a water tank. The first heating component is connected to the water tank through the water pump. When working, under the action of the water pump, the liquid to be heated in the water tank is transported to the first heating component for heating.

[0011] In one embodiment, the main unit further includes a first shell, the water pump and the first heavy heating component are both located in a space formed in the first shell, and the water tank is detachably connected to the first shell.

[0012] In one embodiment, the first heating component includes an instantaneous heater, a water inlet of the instantaneous heater is connected to a water tank, and an outlet of the instantaneous heater is connected to the steam inlet.

[0013] The steam generating device in the above embodiment further defines that the first heating component heats the liquid to be heated for the first time through the instant heating device. Compared with the instant heating device, the instant heating device can heat according to the preset temperature and generate water-containing steam at a precise temperature, which reduces the difficulty of temperature control for the second heating. Specifically, the instant heating device can heat and raise the liquid to be heated to the required temperature immediately when the liquid flows through the internal heating element, without waiting for preheating, thus saving preheating time.

[0014] In one embodiment, the first heating component further includes a thermostat, which is electrically connected to the instant heater, and is used to detect the temperature of the instant heater and control the heating power of the instant heater.

[0015] The steam generating device in the above embodiment is further defined as being arranged on the instant hot heater through a temperature controller and electrically connected to the instant hot heater. It can control the heating power of the instant hot heater by monitoring the heating temperature of the instant hot heater and comparing it with the corresponding threshold temperature, thereby ensuring that the instant hot heater outputs water-containing steam with a stable and precise temperature.

[0016] In one embodiment, the steam channel includes a first flow channel, a second flow channel, a third flow channel, a fourth flow channel and a central flow channel, the first flow channel and the second flow channel are symmetrically distributed on both sides of the central flow channel, the third flow channel and the fourth flow channel are symmetrically distributed on both sides of the central flow channel, the steam inlet is respectively connected to the inlet of the first flow channel and the inlet of the second flow channel, the outlet of the first flow channel and the outlet of the second flow channel are both connected to the inlet of the central flow channel, the outlet of the central flow channel is respectively connected to the inlet of the third flow channel and the inlet of the fourth flow channel, and the outlet of the third flow channel and the outlet of the fourth flow channel are both connected to the exhaust port;

[0017] The third flow channel is disposed adjacent to the first flow channel and is located outside the first flow channel, and the fourth flow channel is disposed adjacent to the second flow channel and is located outside the second flow channel.

[0018] The steam generating device in the above embodiment further defines that the first heating component transports the water-containing steam to the steam inlet through a pipeline, and the water-containing steam enters the steam channel through the steam inlet. With the steam inlet as the base point, the water-containing steam is divided into two parts, one part of the water-containing steam enters the first flow channel, and the other part of the water-containing steam enters the second flow channel. The two parts of the water-containing steam flow out after being heated in the first flow channel and the second flow channel respectively and merge at the central flow channel to continue heating to obtain water-free steam, wherein one part of the water-free steam enters the third flow channel, and the other part of the water-free steam enters the fourth flow channel. The two parts of the water-free steam flow out after being heated in the third flow channel and the fourth flow channel respectively and merge at the exhaust port, and are finally discharged through the exhaust port.

[0019] In one of the embodiments, at least one of the temperature sensors is disposed adjacent to the exhaust port, and at least one of the temperature sensors is disposed adjacent to the central flow channel.

[0020] The steam generating device in the above embodiment further defines at least one temperature sensor for measuring the temperature of the steam channel adjacent to the exhaust port, and in addition, at least one temperature sensor for measuring the temperature of the steam channel adjacent to the central flow channel; specifically, water-containing steam enters the steam channel from the steam inlet, is divided into two parts, flows through the first flow channel and the second flow channel respectively, and then merges at the central flow channel and continues to be heated to obtain water-free steam. According to the temperature value measured by one of the temperature sensors at the central flow channel, if the temperature value is greater than the temperature threshold range, the heating power of the second heating component is reduced or the heating of the second heating component is suspended; if the temperature value is less than the temperature threshold range, the heating power of the second heating component is increased; if the temperature value is within the temperature threshold range, the heating power of the second heating component is maintained to ensure that the steam temperature value measured by the temperature sensor located adjacent to the exhaust port is maintained within the temperature threshold range.

[0021] In one of the embodiments, the second heating component includes a steam cavity and a heating tube, wherein the heating tube is disposed on the steam cavity, and a guide plate is disposed in the steam cavity to separate the interior of the steam cavity to form the steam channel.

[0022] In one embodiment, the steam cavity is made of metal aluminum, and the temperature sensors are placed close to the surface of the steam cavity to measure the corresponding temperature values ​​of the steam cavity at different positions. At least one temperature sensor is arranged in the steam cavity near the exhaust port, and at least one temperature sensor is arranged in the steam cavity near the central flow channel.

[0023] In one embodiment, the heating pipe and the steam chamber are die-cast as one body.

[0024] In the above-mentioned embodiment, it is further defined that the heating pipe and the steam chamber are die-cast into one body to improve the heat transfer efficiency.

[0025] In one embodiment, the heating pipe is strip-shaped and is distributed in the steam cavity in a circuitous manner.

[0026] In the above-mentioned embodiment, it is further defined that the heating pipe is strip-shaped and distributed in the steam cavity in a circuitous manner, so as to increase the contact area between the heating pipe and the steam cavity and improve the heat transfer efficiency.

[0027] A steam generating device control method is applied to the above steam generating device, and the control method comprises the following steps:

[0028] The liquid to be heated is transported to the first heating component, and the heated liquid is heated according to a first preset temperature to obtain water-containing vapor;

[0029] delivering the water-containing steam into the steam channel and heating the water-containing steam according to a second preset temperature to obtain water-free steam;

[0030] One of the temperature sensors measures a first temperature value near the exhaust port, and the other temperature sensor measures a second temperature value away from the exhaust port. If the second temperature value is greater than a temperature threshold range, the second heating component reduces the heating power or stops heating. If the second temperature value is less than the temperature threshold range, the second heating component increases the heating power. If the second temperature value is within the temperature threshold range, the second heating component maintains the heating power to ensure that the first temperature value is maintained within the temperature threshold range.

[0031] The second aspect of the present application discloses a control method for a steam generating device, wherein a liquid to be heated is conveyed to a first heating component for heating at a first preset temperature to obtain water-containing steam of a stable and precise temperature, and then the water-containing steam is conveyed to a steam channel in a second heating component for secondary heating at a second preset temperature. Since the water-containing steam has reached a certain temperature, the second heating component does not need to perform large-span heating and temperature control on the water-containing steam, thereby reducing the difficulty of temperature control of the second heating component. Then, a first temperature value at a location adjacent to the exhaust port and a second temperature value at a location of the steam channel away from the exhaust port are respectively obtained by at least two temperature sensors, and the heating power of the second heating component is controlled by comparing the second temperature value with a temperature threshold range to ensure that the first temperature value measured near the exhaust port is maintained within the temperature threshold range. Through the above-mentioned control method for a steam generating device, the temperature of the steam channel and the ironing panel on which the steam acts is maintained within the temperature threshold range, so that the variation range of the steam temperature in the steam channel is small, thereby achieving low-temperature ironing, so that the steam achieves a better balance in terms of "visual effect", "steam volume" and "stability". Further, if the first temperature value is outside the temperature threshold range, the heating power of the first heating component is adjusted.
