Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements associated with the present invention are shown in the drawings.
The steam refreshing of the clothes means that the odor in the clothes is dissolved and taken away through the steam, so that the odor remained on the clothes is effectively removed. The clothes are refreshed by steam without the steps of washing and drying, so that the effect of removing peculiar smell can be achieved only by spending shorter time. Moreover, the steam only moistens the clothes, and the clothes are dried by slightly airing after being taken out from the inner drum.
As shown in fig. 1, in particular, the method for refreshing dry clothes by using a washing machine provided by the embodiment includes: injecting water into the outer barrel, wherein the water level of the injected water is lower than that of the inner barrel; heating water in the outer drum and generating steam to refresh the clothes in the inner drum; and taking out the clothes in the inner drum for drying.
According to the method for refreshing the dry clothes by using the washing machine, the existing washing machine is adopted to generate steam, the clothes can be refreshed, a device for manufacturing the steam is not required to be additionally arranged, the washing machine is not required to be improved, and the cost of the whole washing machine is not increased. And the water level of the water injection is lower than that of the inner barrel, so that the clothes cannot be soaked, and the clothes can be dried in a short time.
In the present embodiment, the method is used for a drum washing machine as an example, and as shown in fig. 2, the drum washing machine includes an inner drum 1, an outer drum 2 sleeved outside the inner drum 1, and a heating pipe 3, wherein the heating pipe 3 is connected to the outer drum 2 and is located below the inner drum 1. The drum washing machine further comprises a drain pipe 4, a drain pump 5 connected to the drain pipe 4, a water level detection assembly 6, a temperature sensor and an MCU, wherein the water level detection assembly 6 is communicated with a pump hose 9 through a gas collecting valve 7, the water level detection assembly 6 can measure the water level in the outer barrel 2, and the temperature sensor can measure the water temperature in the outer barrel 2. As shown in fig. 3, the heating pipe 3, the water level detecting component 6, the temperature sensor and the power supply are all electrically connected with the MCU. The method generates steam by injecting water into the tub 2 of the washing machine and heating the water in the tub 2 through the heating pipe 3, thereby manufacturing steam without adding an additional steam generating device.
If the clothes are soaked by water in the washing process, the aim of quickly drying the clothes cannot be fulfilled, and the use experience of a user is seriously influenced. Therefore, in the process of steam refreshing the laundry, it is required to ensure that the laundry is not wetted by water. The wall of the inner tub 1 is provided with a plurality of water through holes, so that when the inner tub 1 is used for preventing water from entering the inner tub 1 to soak clothes and refreshing the clothes, the water level of the injected water should be lower than that of the inner tub 1, preferably, in the present embodiment, the injected water level is lower than that of the inner tub, that is, the injected water level is lower than that of the inner tub: the distance between the water surface in the outer cylinder and the bottom wall of the inner cylinder is larger than zero. Meanwhile, in order to avoid the danger caused by dry burning of the heating pipe 3 due to the exposure of the heating pipe 3 outside the water surface, the water level of the injected water should be higher than the upper end of the heating pipe 3. However, the distance between the upper end of the heating pipe 3 and the bottom wall of the inner cylinder 1 is small. Therefore, the accuracy of detection by the water level detection assembly 6 must be ensured.
In this embodiment, in order to eliminate the detection error of the water level detecting assembly 6 and improve the accuracy of measuring the water level height, thereby effectively preventing the water from wetting the clothes and preventing the heating pipe 3 from being exposed to the outside of the water surface, and causing danger, the method for refreshing the clothes with the washing machine further comprises: the water level detection assembly is calibrated before filling water into the outer barrel.
In the present embodiment, the main principle of correcting the water level detecting assembly is to discharge the water in the outer tub until the gas collecting valve is completely exposed to the atmosphere. The gas collecting valve is completely exposed to the atmosphere, and the first possibility is that the water level is just positioned at the lower end of the gas collecting valve, namely the distance between the water level and the gas collecting valve is equal to 0; a second possibility is that the water level is below the gas collecting valve, i.e. the distance between the water level and the gas collecting valve is greater than 0. In the two cases, the values fed back to the MCU by the water level detection assembly are the same and are both F0. F of different water level detecting assembly due to manufacturing error of the water level detecting assembly0With different values, this step enables the MCU to record F of the water level detection assembly0And thereby the calibration of the water level detection assembly is achieved.
When water is injected into the outer barrel, after the water surface is contacted with the gas collecting valve, the value detected by the water level detection assembly begins to change along with the change of the water level, and when the water level in the outer barrel reaches the preset water level, the value change quantity delta F detected by the water level detection assembly is a fixed value, so that the water can be accurately injected to the preset water level through the method.
When the existing washing machine washes, water is directly injected into the outer cylinder, and when the value detected by the water level detection assembly is F, the water level in the outer cylinder is considered to reach the preset water level. The value F ═ F detected by the water level detection component0Δ F, F due to different water level detection assemblies0The values are different, and thus, for different water level detecting assemblies, when the F values are the same, Δ F is different, resulting in different actual water level values. Therefore, the value F detected by the water level detecting assembly in the prior art is taken as a standard, and the actual water level in the outer barrel cannot be accurately reflected.
Therefore, the method for refreshing the dried clothes using the washing machine first corrects the water level detecting assembly to obtain F0And then determining the amount of water to be supplied according to the Δ F value, thereby eliminating manufacturing errors of the water level detecting assembly and allowing the water level in the outer tub to reach a preset water level before steam refreshing of the laundry in the inner tub.
There are two methods of correcting the water level detection assembly. As shown in fig. 4, the first method is that the calibration of the water level detection assembly includes: and (4) draining water of the washing machine until the preset time, wherein the water level reaches the water level of the empty cylinder. The water level of the empty cylinder is any water level of the water surface below the gas collecting valve.
The user may prematurely terminate the program when the laundry is washed last time, or for other reasons, not drain the water in the tub. Therefore, in order to ensure that the water level reaches the empty water level after the preset time of draining, the method further comprises the following steps after the washing machine drains water for the preset time: detecting whether the water level reaches the water level of an empty cylinder;
if the water level reaches the empty cylinder water level, the water level detection assembly is corrected completely;
if the water level of the empty drum is not reached, the washing machine continues to drain water.
In this embodiment, it is possible to detect whether the water in the washing machine reaches the empty tub water level by the following method: and in the drainage process of the drainage pump, detecting whether the value F detected by the water level detection component changes or not. If the F value is stable and unchanged, the water level of the empty cylinder is reached, and the F value is F0The water level detection assembly is corrected; if the F value is still changed, the water level of the empty drum is not reached, and the washing machine continues to drain water.
As shown in fig. 4, a second method of correcting the water level detection assembly is: the washing machine drains water to the empty drum water level. The method directly detects whether the water level reaches the empty cylinder water level.
Preferably, the water level detecting assembly is a frequency type water level sensor, and the value detected by the frequency type water level sensor is a water level frequency. Correcting the water level detection assembly includes: and (4) draining water of the washing machine until the preset time is reached and the water level of the empty cylinder is reached, wherein the water level frequency is kept unchanged. Or correcting the water level detection assembly comprises: the washing machine drains water until the water level frequency detected by the frequency type water level sensor is kept unchanged.
Specifically, the water level frequency F ═ F0-KX. Wherein X is a water level height value, and when the water level is positioned below the gas collecting valve, X is 0; k is a constant; f0The value of the water level frequency is the value of the water level frequency when the water level in the drum washing machine is positioned below the gas collecting valve. Preferably, a preset water level height value can be recorded in the MCU, for example, the preset water level value can be 65mm, and then the frequency F of the water level when the preset water level is reached is calculated1When the water level frequency F transmitted to the MCU by the frequency type water level sensor is the water level frequency F1And when the water is drained, the MCU controls the drainage pump to stop draining water.
As shown in fig. 5, preferably, in order to uniformly refresh the laundry, the inner tub is rotated before the water is filled, and the laundry is shaken up. In this case, the rotation speed of the inner drum may be relatively low, for example, the rotation speed may not exceed 60rpm, for example, 45rpm, as long as the clothes can be shaken off. Further, in the process of refreshing the clothes in the inner drum, the inner drum rotates simultaneously, so that the clothes are always in a shaking and scattering state in the refreshing process.
As shown in fig. 6, the water inlet 8 of the conventional washing machine is provided on the outer tub 2 above the horizontal axis of the outer tub 2. When water is injected, water flows into the outer cylinder 2 from the gap between the inner cylinder 1 and the outer cylinder 2. Since the inner tub 1 is provided with the water through holes, water may flow into the inner tub 1 during the water supply process to wet the laundry.
With continued reference to FIG. 5, while water is injected into the outer barrel, the inner barrel is rotated, causing water droplets that drip onto the outer wall of the inner barrel to be separated from the inner barrel in the tangential direction of the inner barrel under the action of shear stress. Preferably, the rotational speed of the inner barrel does not exceed 60 rpm. In this embodiment, the water inlet is disposed at the upper left of the inner cylinder, and therefore, the inner cylinder rotates counterclockwise, so that water attached to the inner cylinder can be separated from the inner cylinder along the tangential direction of the inner cylinder. Of course, in other embodiments, the water inlet can also be arranged at the upper right part of the inner barrel, and the inner barrel can rotate clockwise. The step can make the water drops dropping on the inner barrel separate from the inner barrel as soon as possible, and prevent the water drops from attaching to the water barrel and flowing into the inner barrel through the limber hole in the rotating process of the water barrel.
Preferably, the step of injecting water into the outer cylinder comprises the following steps: intermittently feeding water into the outer cylinder. That is, water is injected into the outer cylinder for a preset time, and then the water injection is stopped for the preset time, and the step is repeated until the water level detection assembly detects that the water level reaches the preset water level, so that the water injection can be stopped. The preset time for stopping water injection is to enable the injected water to enter the cylinder bottom of the outer cylinder, and the reaction time is reserved for the water level detection assembly to detect the real-time height of the water, so that the water level is effectively prevented from exceeding the preset water level.
Preferably, the water level is detected in real time during the whole water injection process, and the water level is controlled not to exceed a preset high water level and not to be lower than a preset low water level. If the preset water level is reached, refreshing the clothes; if the water level does not reach the preset water level, water is continuously fed.
Preferably, the steam is generated by: and heating the water in the outer barrel to a set temperature, and keeping the water temperature at the set temperature for a set time. In this embodiment, the heating tube heats the water to a set temperature, wherein the set temperature may be 40 ℃ to 100 ℃, preferably 50 ℃ to 90 ℃, for example 65 ℃, and the amount and temperature of the steam in the above temperature range are suitable. The setting time is 1min-30min, such as 20min, and the above time can remove peculiar smell and refresh clothes, and the time is not too long.
Preferably, in the process of refreshing clothes and generating steam, the water in the outer drum is gradually consumed, in order to prevent the heating pipe from being exposed on the water surface, the water level is detected in real time in the whole heating process, and the water level is controlled not to exceed the preset high water level and not to be lower than the preset low water level. If the water level does not reach the preset water level, injecting water into the outer cylinder; and if the water level is in the preset water level, detecting whether the set time is reached. If the set time is reached, the heating pipe stops heating, the water in the washing machine is discharged, the inner drum stops rotating, and the program is ended. In this embodiment, the drain pump is used to drain water from the washing machine, thereby preventing bacteria from growing in the washing machine.
