[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Reference Figures 1 to 5 , is a steam drying machine according to an embodiment of the present invention, comprising a cabinet 100, a fan 200, a first heater 300, a steam mechanism 400 and a control module. The cabinet 100 is provided with a accommodating chamber 110 and an air mixing chamber 120, the accommodating chamber 110 is provided with a first air inlet 111 and a first air outlet 112, the air mixing chamber 120 is provided with a second air inlet 121, and the air mixing chamber 120 is connected with the accommodating chamber 110 through the first air inlet 111; the fan 200 is provided in the cabinet 100 and is used to form an air flow from the air mixing chamber 120 to the accommodating chamber 110 through the first air inlet 111; the first heater 300 is provided in the cabinet 100 and is located in the air mixing chamber 120; the steam mechanism 400 is provided in the cabinet 100 and is located in the air mixing chamber 120, the steam mechanism 400 includes a water boiling pan 410 and a second heater 420, and the second heater 420 can heat the water boiling pan 410 and generate steam; the control module is provided in the cabinet 100 and is electrically connected to the fan 200, the first heater 300 and the steam mechanism 400.

[0037] By setting the air mixing chamber 120, when steam steaming is required, the control module controls the first heater 300, the fan 200 and the steam mechanism 400 to start, the first heater 300 heats the air in the air mixing chamber 120, and the second heater 420 of the steam mechanism 400 heats the water boiling tray 410, and high-temperature steam is generated in the air mixing chamber 120. The high-temperature steam is first mixed with the hot air in the air mixing chamber 120 to reduce the temperature of the steam. Then, the fan 200 blows the hot air with steam into the accommodating chamber 110 to steam the objects. Since the steam generated by the steam mechanism 400 is first mixed with the hot air to cool down and then blown into the accommodating chamber 110, the temperature of the steam contacting the objects will not be too high, thereby reducing the risk of damage to the objects during steam steaming and improving the safety of use.

[0038] Specifically, the steam generated by the steam mechanism 400 first enters the air mixing chamber 120 to mix with the hot air, which can also make the steam partially liquefied into droplets and maintain the small particle droplet state more stably, so as to better penetrate into the interior of the object for hot steaming.

[0039] In the embodiment, the first air inlet 111 is located at the wall of the lower cavity 123 of the accommodating cavity 110, the first air outlet 112 is located at the wall of the upper cavity 122 of the accommodating cavity 110, and the air mixing cavity 120 is located below the accommodating cavity 110. The above arrangement is conducive to the hot air passing through the entire accommodating cavity 110 from bottom to top due to the rising characteristic of hot air. When the steam mechanism 400 generates steam, it is also conducive to driving the steam to pass through the entire accommodating cavity 110 from bottom to top, and the overall hot steaming effect on the items in the accommodating cavity 110 is better.

[0040] It is understandable that, in other embodiments, the first air inlet 111 and the first air outlet 112 may also be located at other positions of the accommodating cavity 110, which is not limited here.

[0041] In the embodiment, the cabinet 100 is provided with a partition plate 130, which divides the mixing chamber 120 and forms an upper chamber 122 and a lower chamber 123. The partition plate 130 is provided with a first connecting port 131 and a second connecting port 132 side by side. The upper chamber 122 is connected to the lower chamber 123 through the first connecting port 131 and the second connecting port 132 respectively. The fan 200 is connected to the partition plate 130 and is located at the first connecting port 131. The first connecting port 131 is opposite to the first air inlet 111 up and down. The steam mechanism 400 is located in the lower chamber 123. The water boiling tray 410 is opposite to the second connecting port 132 up and down. The first heater 300 and the second air inlet 121 are both located in the lower chamber 123.

[0042] In the above-mentioned air mixing chamber 120 structure, when the fan 200 is started, the fan 200 blows air from bottom to top, and the hot air flow of the lower chamber 123 passes through the first connecting port 131, the upper chamber 122 and the first air inlet 111, and is blown into the accommodating chamber 110. At this time, the air flow will form a negative pressure in the upper chamber 122, and the upper chamber 122 can suck the steam generated at the water boiling pan 410 through the second connecting port 132. At this time, the air in the lower chamber 123 can flow to the vicinity of the water boiling pan 410, thereby facilitating the formation of an air path, so that the steam can smoothly enter the upper chamber 122 from the lower chamber 123 through the second connecting port 132, and finally mix with the hot air at the upper chamber 122 and be brought into the accommodating chamber 110, thereby reducing the impact of the hot steam passing through the fan 200 on the fan 200 and improving the service life.

[0043] It is conceivable that in other embodiments, the air mixing chamber 120 may also be integral.

[0044] Specifically, the first heater 300 is a PTC heater, which facilitates automatic control of the temperature of the air entering the air mixing chamber 120, so that the final temperature of the air mixing chamber 120 is relatively stable. It is conceivable that in other embodiments, the first heater 300 can also be a heating structure such as an electric heating tube, an electric heating plate, etc., which is not limited here.

[0045] In the embodiment, the cabinet 100 is further provided with a connecting air duct 140, the first air outlet 112 is connected to the second air inlet 121 through the connecting air duct 140, the connecting air duct 140 is provided with a dehumidification port 150 connected to the outside, and the cabinet 100 is provided with a dehumidification switch mechanism 500, and the dehumidification switch mechanism 500 is used to open or close the dehumidification port 150. Specifically, during steam hot steaming, the dehumidification switch mechanism 500 is in a closed state, at which time the control module can control the steam mechanism 400, the fan 200 and the first heater 300 to work in coordination with each other, forming a circulating high-humidity airflow that passes through the air mixing chamber 120, the accommodating chamber 110 and the connecting air duct 140 in sequence, and performs circulating steam hot steaming, with a high utilization rate of hot air and steam. When drying is required, the dehumidification switch mechanism 500 opens the dehumidification port 150. At this time, the control module can control the fan 200 and the first heater 300 to work, forming a circulating dry airflow that passes through the mixing chamber 120, the accommodating chamber 110 and the connecting air duct 140 in sequence, so as to dry the items in the accommodating chamber 110. Part of the moisture generated by the items can be discharged to the outside through the dehumidification port 150 along with the airflow, thereby reducing the air humidity inside the cabinet 100 for drying.

[0046] In the embodiment, the connecting air duct 140 includes an upper section 141 and two side sections 142. The upper section 141 is located above the accommodating chamber 110 and communicates with the first air outlet 112. The side section 142 communicates with the upper section 141. The two side sections 142 are respectively disposed on the left and right sides of the air mixing chamber 120. The left and right side walls of the air mixing chamber 120 are both provided with second air inlets 121. The two second air inlets 121 are communicated with the two side sections 142 in a one-to-one correspondence. Two first heaters 300 are provided and are respectively disposed at the two second air inlets 121. The above-mentioned connecting air duct 140 is similar to being wrapped around the outside of the accommodating chamber 110 and the air mixing chamber 120. It can reduce the heat loss of the air mixing chamber 120 and the accommodating chamber 110, facilitate maintaining the steam hot steaming temperature or drying temperature, and facilitate forming a sufficiently large air circulation area for the hot air discharged from the first air outlet 112 to quickly circulate to the second air inlet 121.

[0047] In the embodiment, the dehumidification switch mechanism 500 includes a switch member and a switch driver. The switch member is movably arranged on the cabinet 100 and can move to a position of closing or opening the dehumidification port 150. The switch driver is used to drive the switch member to move. Specifically, the switch member can be a plate body, which is slidably connected to the cabinet 100 and can slide to a position of closing or opening the dehumidification port 150. The switch driver can be an electric push rod to drive the plate body to move; or the switch member can be a plate body, which is rotatably connected to the cabinet 100 and can rotate to a position of closing or opening the dehumidification port 150. In this case, the switch driver can be a reduction motor to drive the plate body to rotate.

[0048] It is conceivable that, in other embodiments, the dehumidification switch mechanism 500 may adopt an air valve, and may also open or close the dehumidification port 150 .

[0049] In the embodiment, a condensation and dehumidification mechanism 600 is further included, and the cabinet 100 is provided with a condensation chamber 160. The condensation and dehumidification mechanism 600 is located in the condensation chamber 160, and the condensation chamber 160 is connected to the connecting air duct 140. The condensation chamber 160 is provided, and when the steam dryer is drying, the condensation and dehumidification mechanism 600 can be started to dehumidify the air in the connecting air duct 140, and cooperate with the dehumidification port 150 to simultaneously reduce the air humidity in the cabinet 100, thereby improving the drying efficiency.

[0050] Specifically, the condensation and dehumidification mechanism 600 includes a semiconductor refrigeration sheet, which lowers the air nearby to liquefy the gaseous water in the air and reduce the air humidity. It is understandable that the condensation and dehumidification mechanism 600 can also use heat pump refrigeration to cool the air and dehumidify.

[0051] In the embodiment, the cabinet 100 is provided with a clothes hanging assembly 700, and the clothes hanging assembly 700 is located at the upper end of the accommodating cavity 110; when the clothes hanging assembly 700 is provided, it can be used to hang clothes, so that the steamer can be suitable for hanging and drying household clothes. Specifically, the clothes hanging assembly 700 can be an existing structure such as a hanging rack, which is not limited here.

[0052] In an embodiment, the cabinet 100 is detachably provided with a tray, the tray is arranged in the horizontal direction, at least two trays are provided and arranged in the up-down direction, and the tray is located in the accommodating cavity 110. When the steamer is used for steaming clothes, the tray can be suitable for steaming large clothes such as bedding. When the steamer is used for hot steaming Chinese medicine packages, the tray can be used to place Chinese medicine packages in batches to steam the Chinese medicine packages, and hot steaming can stimulate the medicinal properties of the Chinese medicine packages. Specifically, the number of trays can be set to two, three, four or more, which is not limited here.

[0053] Specifically, when the steamer is only used for steaming Chinese medicine bags, only the tray can be provided. When the steamer is used for steaming clothes, the clothes hanging assembly 700 and the tray can be provided, and the selection is made according to the size of the clothes to be steamed.

[0054] Specifically, the tray has mesh holes, which facilitates hot air to pass through the tray from bottom to top through the entire accommodating cavity 110 .

[0055] Specifically, the two side walls of the accommodating cavity 110 are respectively provided with tray support blocks, and the tray can be placed on the tray support blocks, so that the tray can be detached. It is conceivable that in other embodiments, the tray can also be installed on the cabinet 100 by screw locking to achieve a detachable connection; or the tray can be installed on the cabinet 100 by plugging or snapping, and the time can be detachably connected.

[0056] In the existing steaming and drying method of the steaming and drying machine, when steaming and drying objects, the steam mechanism 400, the first heater 300 and the fan 200 are basically started synchronously, which easily leads to poor steaming effect. The steam is easy to liquefy into droplets and stay on the surface of the object. The steam and the droplets are difficult to penetrate into the interior of the object, affecting the use effect.

[0057] Therefore, this solution also makes the following improvements:

[0058] The present invention also discloses a steaming and drying method, which is applied to the above-mentioned steaming and drying machine and specifically comprises the following steps:

[0059] S10: Adding items to be steamed and dried: placing the items to be steamed and dried into the accommodating chamber 110;

[0060] S20: pre-baking before steaming: the control module controls the first heater 300 and the fan 200 to start, so as to form hot air that is blown from the air mixing chamber 120 into the accommodating chamber 110, thereby heating the accommodating chamber 110 and pre-baking the articles for a period of time;

[0061] S30: Preliminary steam heating: the control module controls the steam mechanism 400 to start generating steam, and cooperates with the first heater 300 and the fan 200 to steam the article for a period of time;

[0062] S40: Later stage steam hot steaming: the control module controls the first heater 300 to be turned off, and uses the second heater 420 to maintain the temperature of the air mixing chamber 120 and the accommodating chamber 110, and continues steam hot steaming for a period of time.

[0063] The steaming step is performed after the pre-baking step before steaming. Firstly, the temperature of the accommodating chamber 110 can be raised first, so that the droplets of steam liquefaction maintain small particles and have strong penetrating ability, which is beneficial to activate the water molecules in the accommodating chamber 110 and penetrate the articles better. Secondly, the process of small particle droplets increasing in volume can be delayed, and high penetrability and high permeability can be maintained for a longer period of time. Thirdly, the pre-baking before steaming can preliminarily dry the articles and open the pores on the surface of the articles, so that the steam and droplets can penetrate deep into the articles and be absorbed by the articles.

[0064] During the later stage of steam steaming, since the temperatures of the accommodating chamber 110 and the air mixing chamber 120 have been basically stable, the first heater 300 can be turned off at this time, and only the heat generated by the second heater 420 can be used to maintain the temperatures of the accommodating chamber 110 and the air mixing chamber 120 for steam steaming, thereby reducing the energy consumption of the steamer.

[0065] Specifically, the steaming and baking method of the present invention, after the later steam hot steaming step, further comprises the following steps:

[0066] S50: Drying the articles: the control module controls the steam mechanism 400 to be turned off, and the control module controls the first heater 300 to be turned on, so as to dry the articles in the accommodating cavity 110 for a period of time.

[0067] When the items are clothes, they are relatively damp after being steamed and need to be dried before they can be used. Therefore, the clothes can be dried again through the item drying process.

[0068] Specifically, when the item is a traditional Chinese medicine package, step S50 is not required. After the traditional Chinese medicine package is steamed and the medicinal properties are stimulated, it can be used directly.

[0069] Specifically, the control module includes a control circuit board, a temperature sensor, a humidity sensor and a timer, and the control circuit board is electrically connected to the temperature sensor, the humidity sensor and the timer. The control circuit board can reasonably control the steaming process according to the feedback of the temperature sensor, the humidity sensor and the timer.

[0070] Specifically, when the steam-dryer is used to steam and dry clothes, in step S20, it also includes: when the control module detects through the temperature sensor that the temperature of the accommodating cavity 110 reaches between 40° C. and 50° C., it enters step S30.

[0071] Specifically, when the steaming and drying machine is used to steam Chinese medicine bags, in step S20, it also includes: when the control module detects that the temperature of the accommodating chamber 110 reaches 40°C to 75°C through the temperature sensor, it enters step S30. In step S30, the control module detects the humidity of the accommodating chamber 110 through the humidity sensor. When the humidity is too low, the steam mechanism 400 is used to humidify; when the humidity is too high, the humidity is reduced through the dehumidification port 150 and the condensation dehumidification mechanism 600.
