In order to make the objects, features and advantages of the present invention more comprehensible, embodiments accompanying the drawings are described in detail below. It is to be understood that the following detailed description is only illustrative of the invention and is not to be taken in a limiting sense. Also, descriptions of prior art components, features, effects, and the like may be omitted. In addition, for convenience of description, only a part of structures related to the present invention, not all of the structures, is shown in the drawings.

The embodiment of the invention provides a clothes dryer.

In some embodiments, the dryer may include a single function dryer.

In other embodiments, the dryer may further include a washer dryer having a drying function.

Fig. 1 is a schematic view of a structure of a dryer in an embodiment of the present invention.

Referring to fig. 1, a dryer 100 according to an embodiment of the present invention includes a cabinet 111, an outer tub 112 fixedly installed in the cabinet 111, an inner tub 113 rotatably installed in the outer tub 112, and a door 114 installed in the outer tub 112 and adapted to open or close the outer tub 112 and the inner tub 113.

In a specific implementation, the dryer 100 further includes a drying system 120 located between the cabinet 111 and the tub 112, and is provided with a drying program adapted to control the drying system 120 to perform an operation of the drying load 200.

Specifically, drying system 120 includes a drying duct 121, and a blower 122, a heating duct 123, and a condenser 124 located in drying duct 121.

Both ends of the drying pipeline 121 are respectively communicated with the inner drum 113, so that the inner space of the drying pipeline 121 and the inner space of the inner drum 113 are communicated to form a drying loop 125.

Drying circuit 125 may include a drying section 126, a condensing section 127, a fan section 128, and a heating section 129 connected in series. Wherein, the drying section 126 is formed by the inner space of the inner drum 113, and the condensing section 127, the fan section 128 and the heating section 129 are formed by the inner space of the drying pipeline 121.

The fan 122 is located within the fan segment 128 and is adapted to drive air flow within the drying circuit 125 to form a circulating drying air stream. The heater 123 is located within the heating section 129 and is adapted to heat cold air within the heating section 129 to form hot air. Condenser 124 is located within condensing section 127 and is adapted to cool the hot humid air from drying section 126 to form cold air.

In specific implementation, cold air in the drying loop 125 flows under the driving of the fan 122 and is heated by the heating pipe 123 to form hot air when passing through the heating section 129, the hot air enters the inner drum 113 (i.e. the drying section 126) under the driving of the fan 122 and exchanges heat with the load 200 in the inner drum 113 to form hot and humid air, and the hot and humid air enters the condensing section 127 under the driving of the fan 122 and forms cold air under the action of the condenser 124; the cold air enters the heating section 129 again under the driving of the fan 122 to be heated to form hot air, and the hot air enters the inner drum 113 again to exchange heat with the load 200, so as to circulate back and forth to dry the load 200.

With continued reference to fig. 1, the clothes dryer 100 provided by the embodiment of the present invention further includes an ozone generating unit 130 adapted to generate ozone within the drying circuit 125.

In some embodiments, ozone generating unit 130 may comprise a conventional ozone generator.

In other embodiments, ozone generating unit 130 can also include an ultraviolet light source having a center wavelength of about 185 nm. When the ultraviolet light source irradiates the dry oxygen, a part of oxygen molecules are activated and dissociated into oxygen atoms, and the oxygen atoms are further combined with the oxygen molecules to form ozone molecules.

In one embodiment, the ozone generating unit 130 may be disposed at the air outlet of the condensing section 127.

When the ozone generating unit 130 is turned on, the ozone generated by the ozone generating unit 130 is adapted to flow in the drying circuit 125 along with the drying air flow in the drying circuit 125 driven by the fan 122. When the ozone reaches the inner tub 113 along with the drying airflow, it can be diffused to the load 200 located in the inner tub 113, so that the load 200 carries a certain concentration of ozone, and thus the load 200 can have a certain smell, i.e., "sun smell".

It has been found that the so-called "solar smell" is due to the fact that oxygen carried in the load 200 is excited by ultraviolet rays to form ozone having a certain concentration. And, with "solar odor", the concentration of ozone is within [0.3ppm,1.5ppm ].

In the embodiment of the present invention, ozone in a concentration range of [0.3ppm,1.5ppm ] may be generated by the ozone generating unit 130, so that when the concentration of ozone is diffused to the load 200 located in the inner tub 113, the load 200 may have "a smell of the sun".

In a specific implementation, the dryer 100 can also include an ozone sensor to collect the concentration of ozone within the drum 113.

In a specific implementation, the drying program of the dryer 100 may include a primary drying phase and a cooling phase following the primary drying phase.

In a specific implementation, the ozone generating unit 130 can be controlled to generate ozone with a certain concentration in the primary drying stage and the cooling stage, respectively, so that the load 200 in the inner drum 113 has a "sun smell".

Embodiments of the present invention also provide a method for a dryer 100.

FIG. 2 is a schematic flow diagram of a method for a dryer in an embodiment of the present invention.

Referring to fig. 2, a method 300 for a dryer according to an embodiment of the present invention may include the following steps:

s310, running a drying program;

s320, periodically turning on and off the ozone generating unit 130 in the primary drying stage to make the drying loop 125 have a first ozone concentration;

s330, the ozone generating unit 130 is periodically turned on and off in the cooling stage so that the drying circuit 125 has the second ozone concentration.

To provide the load 200 with a "solar scent," in implementations, both the first ozone concentration and the second ozone concentration can be within a particular concentration range.

In some embodiments, a particular concentration range may be located at [0.3ppm,1.5ppm ].

In some embodiments, the first ozone concentration may be equal to the second ozone concentration, and both may be at [0.3ppm,1.5ppm ].

In a specific implementation, the first ozone concentration and the second ozone concentration can both be within a specific concentration range by controlling the time period for which ozone generating unit 130 is turned on and off.

In order to avoid the generation of unpleasant odor due to the high ozone concentration caused by the long on time of the ozone generating unit 130, the ozone generating unit 130 can be turned off for a period of time after being turned on for a period of time.

However, after the ozone generating unit 130 is turned off, the concentration of ozone attached to the load 200 is reduced due to the continuous diffusion of ozone, and thus the load no longer has "solar smell". Therefore, ozone generating unit 130 can be turned on again after ozone generating unit 130 is turned off for a certain period of time.

Specifically, the ozone generating unit 130 may be periodically turned on and off at the primary drying stage and the cooling stage, respectively.

In one period of the primary drying stage in which the ozone generating unit 130 is periodically turned on and off, a time period for turning on the ozone generating unit 130 may be a first time period, and a time period for turning off the ozone generating unit 130 may be a second time period.

In one of the cycles of the cooling phase in which ozone generating unit 130 is periodically turned on and off, the time period for turning on ozone generating unit 130 may be a third time period, and the time period for turning off ozone generating unit 130 may be a fourth time period.

In particular implementations, the first and third time periods may each be adjusted based on the weight of the load 200, and the greater the weight of the load 200, the longer each of the first and third time periods. Because, the greater the weight of the load 200, the more ozone is required to make it "sun scent".

In particular implementations, the first and third time periods may also be adjusted based on the volume of the drying circuit 125, and the greater the volume of the drying circuit 125, the longer both the first and third time periods. Because, the larger the volume of the drying circuit 125, the more ozone is needed to make the load 200 inside it have a "sun smell".

In an implementation, for different volumes of the drying circuit 125 and different weights of the load 200, a first time period and a third time period for the ozone generating unit 130 to be turned on when the corresponding load 200 has "smell of sun" can be obtained respectively.

In some embodiments, for a drying circuit 125 having a volume [55l,75l ], when the weight of the load 200 is [1kg,2kg ], the first and third time periods may both be [10s,90s ]; when the weight of the load 200 is at [2kg,4kg ], the first and third periods may both be at [30s,180s ]; when the weight of the load is set to [4kg,6kg ], the first period and the third period may be both set to [60s,300s ].

In some embodiments, the concentration of ozone generated during the primary drying stage and the cooling stage may be the same or similar. In this case, the third duration may be greater than the first duration. This is because the temperature of the cooling stage is lower and the ozone generation rate is slower than that of the main drying stage, so that the on-time of the ozone generating unit 130 in one cycle of the cooling stage can be longer to make the concentration of the ozone generated in the cooling stage the same as or similar to that of the main drying stage.

In other embodiments, the concentration of ozone generated during the primary drying stage and the cooling stage may be different. In this case, the third duration may be equal to the first duration.

In some embodiments, the first duration and the third duration may each be less than the second duration or the fourth duration. For example, the first duration and the third duration may both be less than the second duration. For another example, the first duration and the third duration may both be less than the fourth duration.

In other embodiments, the first duration and the third duration may each be less than the lesser of the second duration and the fourth duration.

In still other embodiments, the first duration may be less than the second duration and the third duration may be less than the fourth duration.

Based on the above, the time period for turning on ozone generating unit 130 can be less than the time period for turning off ozone generating unit 130, whether in one cycle of the primary drying phase or in one cycle of the cooling phase. This is because the ozone generating unit 130 is turned on for a long time, which causes the concentration of ozone to be high, thereby generating unpleasant odor.

In some embodiments, the second duration may be equal to the fourth duration.

In some embodiments, the second and fourth durations may both be at [5min,10min ].

In some embodiments, the operating the drying process in step S310 may include operating the drying process such that the final moisture content of the load 200 after being dried is less than or equal to 1%. When the final water content of the load 200 is less than or equal to 1%, it is more advantageous to adsorb ozone. As such, it is also more advantageous for the load 200 to have "solar smell".

Fig. 3 is a schematic flow chart of the embodiment of the present invention for periodically turning on and off the ozone generating unit in the primary drying stage.

Referring to fig. 3, the periodically turning on and off the ozone generating unit 130 in the primary drying stage as described in step S320 may include:

s321, operating the ozone generating unit 130 and turning it on for a first time period;

s322, judging whether the primary drying stage is finished, if not, going to step S323,

s323, judging whether the current main drying remaining time is greater than a second time length, turning to the step S324 when the current main drying remaining time is greater than the second time length, and returning to the step S322 when the current main drying remaining time is less than or equal to the second time length;

s324, after waiting for the second time period, returning to the step S321 until the end of the primary drying stage.

Based on the above, in the primary drying stage, the ozone generating unit 130 can be periodically turned on for a first time period and the ozone generating unit 130 can be periodically turned off for a second time period.

After the first time period of the ozone generating unit 130 being turned on, it may be judged whether or not it is necessary to continue to turn on the ozone generating unit 130 at the first time period based on the main drying remaining time.

Specifically, when the current main drying remaining time is longer than the second time period, it may wait for the second time period and then return to step S321 to continue operating ozone generating unit 130 and turn it on for the first time period. When the current remaining primary drying time is less than or equal to the second time, ozone generating unit 130 does not need to be turned on again in the primary drying stage, in which case, the step S322 may be returned to continuously determine whether the primary drying stage is finished.

With continued reference to fig. 3, in some embodiments, periodically turning on and off ozone generating unit 130 during the primary drying phase as described in step S320 may further include:

s325, when the primary drying stage is finished, judging whether the ozone generating unit 130 is started, and turning to the step S326 when the ozone generating unit 130 is started;

s326, the ozone generating unit 130 is turned off.

Thus, the ozone generating unit 130 can be turned off in time after the main drying stage is finished, so that the subsequent operation of the main drying stage can be smoothly performed.

Figure 4 is a schematic flow diagram of an embodiment of the present invention in which the ozone generating unit is periodically turned on and off during the cooling phase.

Referring to fig. 4, the periodically turning on and off the ozone generating unit 130 in the cooling stage as described in step S330 may include:

s331, operating the ozone generating unit 130 and turning it on for a third time period;

s332, judging whether the cooling stage is finished or not, and turning to the step S333 when the cooling stage is not finished;

s333, judging whether the current cooling residual time is longer than a fourth time length, turning to the step S334 when the current cooling residual time is longer than the fourth time length, and returning to the step S332 when the current cooling residual time is shorter than or equal to the fourth time length;

s334, after waiting for the fourth time, returns to step S331 until the cooling phase is finished.

Based on the above, in the cooling phase, the ozone generating unit 130 can be periodically turned on for the third time period and the ozone generating unit 130 can be periodically turned off for the fourth time period.

After the ozone generating unit 130 is turned on for the third time period, whether the ozone generating unit 130 needs to be turned on for the third time period subsequently can be judged based on the cooling remaining time.

Specifically, when the current cooling remaining time is longer than the fourth time period, the operation may be continued and the ozone generating unit 130 may be turned on for the third time period by returning to step S331 after waiting for the fourth time period. When the remaining cooling time is less than or equal to the fourth time, ozone generating unit 130 does not need to be turned on again in the cooling stage, in which case, it can return to step S332 to continue to determine whether the cooling stage is finished.

In some embodiments, the cooling phase is the last phase of the drying program. And after the cooling stage is finished, the drying program is finished. If the ozone generating unit 130 is turned off after the cooling period is finished, there is a possibility that the user opens the door 114 and takes the load 200 to be harmful to the health of the user due to excessive ozone remaining in the inner tub 113.

In an implementation, the ozone generating unit 130 can be turned off for a period of time before the cooling stage is finished, so that the concentration of ozone in the inner drum 113 can be attenuated to a certain degree before the drying process is finished, and the ozone remaining in the inner drum 113 can be attenuated to a range safe to human health at the end of the drying process.

In some embodiments, the periodically turning on and off the ozone generating unit 130 during the primary drying phase as described in step S330 may further include turning off the ozone generating unit 130 before the cooling phase is finished.

With continued reference to fig. 4, in a specific implementation, the periodically turning on and off the ozone generating unit 130 in the primary drying stage in step S330 may further include:

s335, when the cooling stage is not finished, judging whether the finishing time of the cooling stage is less than or equal to the time threshold, when the finishing time of the cooling stage is less than or equal to the time threshold, turning to the step S336, and when the finishing time of the cooling stage is greater than the time threshold, continuously judging whether the finishing time of the cooling stage is less than or equal to the time threshold;

s336, judging whether the ozone generating unit 130 is started, turning to the step S337 when the ozone generating unit 130 is started, and ending when the ozone generating unit 130 is not started;

s337, the ozone generating unit 130 is turned off.

In a specific implementation, the concentration of ozone in the inner barrel 113 can be attenuated to a safe range for human health within a time period less than or equal to the time threshold, so as to avoid the damage of ozone to human health.
