Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of steam box devices, in particular to a steam box and a method for detecting and determining blockage thereof. Background Art
[0002] At present, some high-end washing and drying integrated machines are equipped with a steam care function. Tap water generates steam through an electric heater in the steam box and then is introduced into the drum to care for clothes, in order to achieve functions such as wrinkle removal and odor removal. After long-term use, scale will be generated and accumulated in the steam box. The scale may block the steam outlet, resulting in the inability to discharge steam and the failure of the function. If not processed in time, dangers such as explosion may occur. Therefore, it is crucial to identify the blockage and give an early warning for protection.
[0003] The existing technology mainly adopts a pressure relief method. When the pressure in the water box is relatively high, water or steam is drained through a pressure relief hole. However, this method does not give an early warning, and the result is that water may leak into the machine body or the floor, and steam may condense at parts such as the terminal block, leading to potential safety hazards. Another method is to add a pressure sensor. When the pressure rises to a certain value, it is judged that there may be a blockage and an early warning is given. However, due to the addition of a pressure sensor and the corresponding control circuit, the use cost is relatively high. Summary of the Invention
[0004] In order to overcome the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a steam box capable of quickly judging blockage and a method for detecting and determining blockage thereof.
[0005] The technical solution adopted by the present invention to solve its technical problems is: a method for detecting and determining blockage of a steam box, including the following steps:
[0006] (1) After the steam generating device is started, the heater starts to work, and the temperature thermosensitive package detects the temperature in the steam generating device in real time;
[0007] (2) Judge that the temperature T steam in the steam device is detected continuously for n1 seconds ≥ T1;
[0008] If so, after the heater stops working for n2 seconds, the liquid level probe starts to detect, and enter step (4);
[0009] If not, enter step (3);
[0010] (3) The heater continues to work and runs the steam function, and enter step (5);
[0011] (4) Judge the actual water level value W 液位 > the water level value W at which the heater dries out 断开 ;
[0012] If so, the water inlet valve intakes water by M1 L, the heater is turned on, and enter step (5);
[0013] If not, the water inlet valve fills water by M2 L and returns to step (1);
[0014] (5) Determine that the temperature T_steam in the steam device is detected to be ≥ T1 for n1 consecutive seconds;
[0015] If so, the heater stops heating and sends an alarm signal;
[0016] If not, return to step (3).
[0017] As a further improvement of the present invention: the T1 is set according to the relationship that the steam temperature and pressure in the closed space are proportional and the temperature value corresponding to the pressure suitable for preventing the steam box from being damaged.
[0018] As a further improvement of the present invention: the T1 > 100 °C.
[0019] As a further improvement of the present invention: the T1 is 105 °C.
[0020] As a further improvement of the present invention: in the step (1), when the actual water level value W 液位 > the water level value W at which the heater dries out 断开 , the heater starts to heat the water in the generating device, and the temperature thermosensitive package detects the temperature in the steam generating device in real time.
[0021] As a further improvement of the present invention: in the step (2), after the heater stops working for n2 seconds, the liquid level probe starts to detect the water level value to prevent the bubbles generated by heating from interfering with the accuracy of water level detection.
[0022] As a further improvement of the present invention: in the step (4), when the actual water level value W 液位 > the water level value W at which the heater dries out 断开 , it indicates that there is still a surplus of water in the steam generating device at this time. The water inlet valve only needs to replenish water by M1 liters and then continue heating to reduce the temperature in the water box, thereby reducing the pressure in the device. The gas in the steam outlet pipe forms an internal reverse pressure, which may cause the scale blocking the steam outlet hole to fall off; high-pressure water inlet will cause the water surface to roll, and surface tension is formed between the liquid surface and the inner wall of the steam box, which may also drive the scale blocking the steam outlet hole to fall off; it indicates that the blockage determination has been lifted, and the steam heating function continues to operate until the steam demand is met.
[0023] As a further improvement of the present invention: in the step (4), if the detected actual water level value W_liquid level ≤ W_disconnection at this time, it indicates that the water volume is insufficient and there may be a risk of dry burning. After the water inlet valve directly replenishes water by M2 liters, it returns to the start and continues to operate and cycle detection until the steam demand is met.
[0024] As a further improvement of the present invention: in the step (4), the makeup water amounts M1 and M2 are measured by the flowmeter on the water inlet valve.
[0025] As a further improvement of the present invention: in the step (4), the makeup water amount M1 should be less than the volume formed at the position below the lower edge horizontal plane of the water outlet pipe orifice in the steam generating device and above the upper surface horizontal plane of the electric heater, so as to avoid excessive makeup water entering the washing tub, causing uneven moisture absorption of the clothes and destroying the effect of uniformly humidifying the clothes with steam.
[0026] As a further improvement of the present invention: the makeup water amount M2 is less than the volume formed at the position below the lower edge horizontal plane of the water outlet pipe orifice in the steam generating device, so as to avoid excessive makeup water entering the washing tub, causing uneven moisture absorption of the clothes and destroying the effect of uniformly humidifying the clothes with steam.
[0027] As a further improvement of the present invention: M2 > M1.
[0028] As a further improvement of the present invention: M1 < 0.5L.
[0029] As a further improvement of the present invention: M2 < 1L.
[0030] The present invention also provides a steam box applied to the above steam box blockage detection and determination method, including a steam device assembly, a water inlet pipe, a water outlet pipe, a steam outlet pipe, a heater and a temperature sensing package assembly. The steam device assembly is connected to the water inlet pipe, the water outlet pipe and the steam outlet pipe. A flowmeter water inlet valve is provided on the water inlet pipe. A liquid level probe is provided in the steam device assembly. The heater and temperature sensing package assembly, the liquid level probe and the flowmeter water inlet valve are connected to a control assembly.
[0031] As a further improvement of the present invention: the heater and temperature sensing package assembly is arranged in the steam device assembly or the heater and temperature sensing package assembly is connected to the steam device assembly.
[0032] Compared with the prior art, the beneficial effects of the present invention are: using the temperature sensing package in the existing steam box to indirectly determine the pressure, the detection is convenient, and through the secondary confirmation of the water level, the result is accurate; giving early warning to the user to avoid property loss or potential safety hazards; based on the existing structure of the steam box, the overall machine cost is not increased.

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0041] Now, the present invention will be further described in conjunction with the accompanying drawings and embodiments: As Figure 1 shown, a blockage detection and determination method for a steam cartridge includes the following steps:
[0042] (1) After the steam generating device is started, the heater starts to work, and the temperature sensing package detects the temperature inside the steam generating device in real time;
[0043] (2) Determine that the temperature T_steam in the steam device is detected to be ≥ T1 for n1 consecutive seconds;
[0044] If so, after the heater stops working for n2 seconds, the liquid level probe starts to detect, and proceed to step (4);
[0045] If not, proceed to step (3);
[0046] (3) The heater continues to work and runs the steam function, and proceed to step (5);
[0047] (4) Determine the actual water level value W 液位 > the water level value W at which the heater dries out 断开 ;
[0048] If so, the water inlet valve fills with water by M1 L, the heater is turned on, and proceed to step (5);
[0049] If not, the water inlet valve fills with water by M2 L, and return to step (1);
[0050] (5) Determine that the temperature T_steam in the steam device is detected to be ≥ T1 for n1 consecutive seconds;
[0051] If so, the heater stops heating and sends an alarm signal;
[0052] If not, return to step (3).
[0053] As an embodiment of the present invention, in step (2), when the temperature T_steam in the steam generating device is detected to be ≥ T1 for n1 consecutive seconds,
[0054] As an embodiment of the present invention, the T1 is set according to the relationship that the steam temperature and pressure in the closed space are proportional, and the temperature value corresponding to the pressure suitable for preventing the steam box from being damaged; the T1 > 100 °C.
[0055] As an embodiment of the present invention, in step (1), when the actual water level value W 液位 > the water level value W at which the heater dries out 断开 , the heater starts to heat the water in the generating device, and the temperature sensing element continuously detects the temperature in the steam generating device.
[0056] As an embodiment of the present invention, in step (2), the heater stops working for n2 seconds first, and then the liquid level probe starts to detect the water level value, preventing the bubbles generated by heating from interfering with the accuracy of water level detection.
[0057] As an embodiment of the present invention, in step (4), the actual water level value W 液位 > the water level value W at which the heater dries out 断开, it indicates that there is still a surplus of water in the steam generating device at this time. The water inlet valve only needs to replenish M1 liters of water and then continue heating to reduce the temperature in the water box, thereby reducing the pressure inside the device. The pressure of the gas in the steam outlet pipe forms an internal reverse pressure, which may cause the scale blocking the steam outlet holes to fall off; the high-pressure water inlet will cause the water surface to roll, and a surface tension will be formed between the liquid level and the inner wall of the steam box, which may also drive the scale blocking the steam outlet holes to fall off; it indicates that the blockage determination has been lifted, and the steam heating function continues to operate until the steam demand is met.
[0058] As an embodiment of the present invention, if the actual water level value W liquid level detected at this time in step (4) ≤ W disconnection, it indicates that the water volume is insufficient and there may be a risk of dry burning. After the water inlet valve directly replenishes M2 liters of water, it returns to the beginning and continues to operate and cycle detection until the steam demand is met.
[0059] As an embodiment of the present invention, the water replenishment amounts M1 and M2 in step (4) are measured by the flow meter on the water inlet valve.
[0060] As an embodiment of the present invention, the water replenishment amount M1 in step (4) needs to be less than the volume formed at the position below the lower edge horizontal plane of the water outlet pipe nozzle in the steam generating device and above the upper surface horizontal plane of the electric heater, to avoid excessive water replenishment entering the washing tub and causing uneven moisture absorption of the clothes, thereby destroying the effect of evenly humidifying the clothes with steam.
[0061] As an embodiment of the present invention, the water replenishment amount M2 is less than the volume formed at the position below the lower edge horizontal plane of the water outlet pipe nozzle in the steam generating device, to avoid excessive water replenishment entering the washing tub and causing uneven moisture absorption of the clothes, thereby destroying the effect of evenly humidifying the clothes with steam.
[0062] Further, M2 > M1; M1 < 0.5L; M2 < 1L.
