[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] The term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this application. In the description of this application, it should be understood that the terms "upper," "lower," "top," "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Moreover, the terms "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0028] When a numerical range is disclosed herein, the range is considered continuous and includes the minimum and maximum values ​​of the range, as well as every value between the minimum and maximum values. Furthermore, when the range refers to an integer, it includes every integer between the minimum and maximum values ​​of the range. Additionally, when multiple ranges are provided to describe a feature or characteristic, the ranges may be combined. In other words, unless otherwise specified, all ranges disclosed herein should be understood to include any and all subranges to which they are included. For example, a specified range from “1 to 10” should be considered to include any and all subranges between the minimum value 1 and the maximum value 10. Exemplary subranges of the range 1 to 10 include, but are not limited to, 1 to 6.1, 3.5 to 7.8, 5.5 to 10, etc.

[0029] Traditional dishwashers employ a drying unit consisting of a PTC (Potential Thermal Capacitor), drying duct, and fan, resulting in a complex structure and redundant components. Furthermore, the DC carbon brush motors used in existing convection fans have limited lifespans, and moisture easily remains inside the convection drying duct, leading to mold growth in a humid environment that is difficult to treat. The drying temperature is fixed and cannot be adjusted. Convection drying methods result in weak airflow, long drying times, and uneven airflow, leaving dishes in blind spots from the airflow and causing poor drying performance. Moreover, these drying technologies require adding at least one PTC and at least two fans to the basic dishwasher structure, leading to high overall cost and complex installation.

[0030] To address the aforementioned technical problems, this application provides a dishwasher that can generate uniformly flowing drying air and adjust the temperature of the drying air, thereby overcoming the defects caused by the aforementioned technical problems.

[0031] Please see Figure 1 ,like Figure 1 As shown, this application provides a dishwasher, which includes a dishwasher body 1 with an air outlet 12, a drying device 2 and a humidity detection device 3. The drying device 2 is disposed inside the dishwasher body 1 and includes a heating circuit 21, a heating device 201 and a temperature control device. The humidity detection device 3 is disposed at the air outlet 12.

[0032] The temperature control device is electrically connected to the heating device 201, the heating device 201 and the temperature control device are respectively electrically connected to the heating circuit 21, and the humidity detection device 3 is electrically connected to the temperature control device.

[0033] Optionally, the humidity detection device 3 can be fixedly connected to the outer shell of the dishwasher body 1 and installed at the air outlet 12, or it can be detachably installed at the air outlet 12.

[0034] Optionally, the heating device 201 is a device for heating the drying air, and can be a component such as a heating tube. The heating circuit 21 can be a PWM circuit, which can change the voltage by adjusting the duty cycle, thereby controlling the operation of the heating device 201. The temperature control device is a device for controlling the temperature of the drying air. It controls the heating device 201 by acquiring the humidity detected by the humidity detection device 3, and finally realizes the adjustment of the temperature of the drying air.

[0035] The dishwasher provided in this embodiment of the utility model, by setting a heating device, a temperature control device, a humidity detection device, and a heating circuit in the drying device, uses the heating circuit to control the temperature control device to adjust the temperature of the heating device so that the temperature of the heating device is within the control range, thereby controlling the temperature of the drying air to meet the drying needs of different objects. The temperature of the heating device is further adjusted based on the actual humidity value detected by the humidity detection device. By using the heating device to heat the air inside the dishwasher body, the drying efficiency is improved, the drying time is shortened, and the cost is reduced.

[0036] Please continue reading Figure 1 ,like Figure 1 As shown, the dishwasher includes a dishwasher body 1, a drying device 2, and a humidity detection device 3 installed at the dishwasher air outlet 12. Exemplarily, from the structure of one embodiment of this application, the dishwasher body 1 can be divided into a drying area above the partition 13 and a drying device 2 area below the partition 13, with the partition 13 carrying the object to be dried 4 as the boundary. The drying area is used to place the object to be dried 4, such as tableware such as bowls, chopsticks, and spoons, while the drying device 2 area is used to arrange the specific structural components of the drying device 2.

[0037] Please continue reading Figure 1 ,like Figure 1 As shown by the dashed line trajectory, exemplarily, drying air enters the dishwasher body 1 from the air inlet 11. The drive device 24 drives the pressurization device 23 to pressurize the air, causing the air to drive the air delivery device 22 to rotate, making the drying air flow towards the drying zone, forming the flow trajectory shown in the figure. At the same time, the heating circuit 21 controls the heating device 201 to heat the drying air, so that the drying air is heated as it flows through the heating device 201, thus making the drying air blown towards the drying zone hot air, thereby achieving the drying effect.

[0038] In some possible implementations, the temperature control device includes a temperature measuring device 202 and a temperature control switch 203 that are electrically connected to each other.

[0039] Optionally, the temperature measuring device 202 is used to measure the actual temperature of the heating device 201. By comparing the actual temperature measured by the temperature measuring device 202 with the set temperature, the comparison result is fed back to the temperature control switch 203. The temperature control switch 203 adjusts the heating of the heating device 201 accordingly, and controls the temperature of the drying air by controlling the power of the heating device 201. The actual temperature is the temperature of the heating device 201 measured in real time, and the preset temperature is the desired temperature of the heating device 201 set through input programs or other means.

[0040] For example, the temperature measuring device 202 can be a temperature sensor, a temperature and humidity sensor or other devices, and the temperature control switch 203 can be a transistor, a thyristor, or an electronic power transistor such as a MOSFET or an IGBT.

[0041] For example, if the actual temperature is lower than the set temperature, the temperature control switch 203 controls the heating device 201 to heat further; if the actual temperature is higher than the set temperature, the temperature control switch 203 controls the heating device 201 to stop heating, thereby adjusting the temperature to around the set temperature.

[0042] This embodiment of the invention incorporates a temperature measuring device and a temperature control switch in the temperature control unit. This allows the dishwasher to compare the actual temperature of the heating device with the preset temperature, and then adjust the temperature control switch accordingly to keep the temperature of the heating device within the range of the set temperature. This ensures the stability of the drying air temperature, guarantees the uniformity and stability of drying, and prevents damage to the items being dried due to excessively high temperatures.

[0043] In some possible implementations, the temperature control device includes a signal receiving module, and the humidity detection device 3 includes a signal generating module and a signal transmitting module, wherein the signal receiving module is electrically connected to the signal transmitting module.

[0044] For example, the humidity detection device 3 is used to measure the actual humidity value in real time and transmit the actual humidity value to other devices. The signal generation module is used to detect the humidity at the air outlet 12 of the dishwasher and generate a humidity signal, while the signal transmission module is used to transmit the humidity signal from the humidity detection device 3 to other devices.

[0045] Optionally, the temperature control device includes a signal receiving module for receiving humidity signals. The humidity signal is the result of humidity detection by the humidity detection device 3 at the dishwasher's air outlet 12, reflecting the moisture content of the air blown from the dishwasher body 1. This allows for determination of whether the drying process inside the dishwasher is sufficient. By judging the humidity level, the drying temperature can be controlled and the remaining drying time can be flexibly adjusted. Accordingly, low humidity indicates that the drying process inside the dishwasher is relatively thorough; conversely, high humidity indicates that the drying process inside the dishwasher is insufficient.

[0046] This embodiment of the invention establishes an electrical connection between the temperature control device and the humidity detection device. By setting up a signal generation module, a signal transmission module, and a signal receiving module, the temperature control device can promptly control the temperature based on the real-time measured actual humidity value. This improves the reliability of the dishwasher's drying temperature control, allowing the drying temperature to change according to the real-time measured actual humidity value, thus enhancing the intelligence and flexibility of the dishwasher's drying effect control.

[0047] In some possible implementations, the drying device 2 further includes an air supply device 22 and a pressurizing device 23. The air supply device 22 and the heating device 201 are respectively disposed on the peripheral structure of the outlet of the pressurizing device 23. The air supply device 22, the pressurizing device 23 and the heating device 201 are independent of each other.

[0048] Optionally, the air supply device 22 is a device for blowing drying air towards the object 4 to be dried, and the pressurizing device 23 is a device for pressurizing the air to drive the air supply device 22. Further, the air supply device 22 can be a device with blades, the blade surface having an inclined surface, capable of generating airflow perpendicular to the blade surface during rotation, for example, a fan-type air supply device 22. Figure 1 As shown by the dashed flow trajectory, the air supply device 22 rotates, driving the heated drying air to flow upward to the drying zone.

[0049] It should be noted that the air at the outlet of the booster device 23 is used to drive the air supply device 22 to rotate. Therefore, the air supply device 22 needs to be installed on the peripheral structure of the outlet of the booster device 23 so that the boosted air can directly act on the air supply device 22, thereby improving the efficiency of energy transfer between the air and the air supply device 22. Also, since the drying air needs to be heated by the heating device 201, the air supply device 22 generates air perpendicular to the surface of the blades after it rotates. Placing the heating device 201 on the peripheral structure of the outlet of the booster device 23 allows the heating device 201 to come into contact with the drying air generated by the rotation of the air supply device 22 as soon as possible.

[0050] This embodiment of the invention arranges the air supply device and the heating device on the periphery of the outlet of the pressurizing device, so that the flowing hot air dries the dishes and provides a high-temperature disinfection effect.

[0051] In some possible implementations, the drying device 2 further includes a drive device 24, which is electrically connected to the pressurizing device 23 and the humidity detection device 3.

[0052] Optionally, the drive unit 24 is used to drive the booster unit 23. For example, the drive unit 24 can be a motor, and to extend the life of the drying unit 2, the motor can preferably be a brushless motor. The humidity detection device 3 feeds back the measured actual humidity value to the drive unit 24, and the drive unit 24 controls the start, operation and stop of the drying process based on this value.

[0053] This invention improves the lifespan of the drying unit in a dishwasher by using a brushless motor or other drive device to pressurize the air, thereby enhancing the dishwasher's durability, reducing the repair rate, and lowering machine maintenance costs.

[0054] In some possible implementations, the dishwasher also includes a timing device electrically connected to the drying unit 2.

[0055] Optionally, the timing device is used to record the actual drying time. The actual drying time refers to the cumulative duration of actual operation of the drying device 2. The preset drying time is the specified operating time of the drying device 2 set by the program, representing the maximum operating time of the drying device 2. The actual drying time can serve as a supplementary criterion for stopping drying. In the event of a malfunction of the humidity detection device 3, the actual humidity may have reached the required level, but the humidity displayed by the humidity detection device 3 may not have reached the required level, causing the drying process to continue without stopping. This could not only damage the object being dried but also lead to energy waste. Setting a preset drying time to control the maximum value of the actual drying time can prevent over-drying.

[0056] This utility model embodiment connects the timing device to the drying device electrically, enabling communication between the actual drying time, preset drying time, and other information with the drying device, thus allowing for reasonable control of the drying device's operation.

[0057] In some possible implementations, the drying device 2 further includes a drying signal generation module and a drying signal transmission module that are electrically connected to each other, and the timing device includes a drying time recording module, a time signal generation module, and a time signal transmission module that are electrically connected to each other;

[0058] The drying signal transmitting module is electrically connected to the drying time recording module, and the time signal transmitting module is electrically connected to the temperature control device.

[0059] To adapt to different drying conditions, the program can be set to achieve the desired drying effect. For example, different drying temperatures can be set for bowls with different heat resistance.

[0060] It should be noted that the drying effect can be represented by the actual humidity value. Optionally, the actual humidity value is the humidity value at the outlet of the dishwasher body 1 detected in real time by the humidity detection device 3. The real-time measured humidity value is compared with the preset humidity value. Based on the comparison result, it is determined whether the drying degree is complete, and then the drying process is controlled to continue or stop. The preset humidity value is the standard humidity value set by the program to determine whether the drying is sufficient.

[0061] Optionally, the drying process may be stopped under at least two conditions: condition one is that the actual humidity value is less than or equal to the preset humidity value; condition two is that the actual humidity value is greater than the preset humidity value and the actual drying time is equal to or greater than the preset drying time; when one of the conditions is met, the drying process is stopped.

[0062] To better understand the stopping conditions of the drying process described above, the following explanation is provided: When drying begins, the drying time is recorded, and the actual humidity value at air outlet 12 is continuously compared with the preset humidity value. Different processing steps are performed based on different comparison results.

[0063] (1) The actual humidity value is greater than the preset humidity value (humidity detection device 3 is normal).

[0064] This indicates that there is still a lot of moisture and high humidity inside the dishwasher body 1, and it needs to continue drying. At the same time, the actual drying time should continue to be recorded.

[0065] (2) The actual humidity value is greater than the preset humidity value (humidity detection device 3 is malfunctioning).

[0066] Determine if the actual drying time has reached the preset drying time. If the drying time has been reached, stop drying, stop the motor, stop recording the actual drying time, and reset the actual drying time to zero; if the preset drying time has not been reached, continue drying.

[0067] (3) The actual humidity value is less than or equal to the preset humidity value.

[0068] If the actual humidity value is less than the preset humidity value, it indicates that there is less moisture and the humidity inside the dishwasher body 1 is low, which is lower than the standard value for stopping drying. Therefore, drying will stop, the motor will stop rotating, the recording of drying time will stop, and the drying time will be reset to zero.

[0069] This utility model embodiment sets two stop conditions for the drying process, including a humidity condition and a drying time condition. The actual humidity value is compared with the preset humidity value, and the actual drying time is compared with the preset drying time. The degree of progress of the drying process is judged, and a decision is made to continue or stop the drying process, thereby improving the reliability of the drying process control.

[0070] In some possible implementations, the booster device 23 includes a turbine and a worm, one end of which is disposed within the turbine, and the other end of which is rotatably connected to the drive device 24.

[0071] For example, the drive device 24 is a DC brushless motor. The brushless motor weakens the field to increase the speed and drives the worm to rotate at high speed in the turbine. The air is pressurized in the turbine, and the pressurized air drives the air supply device 22 to rotate.

[0072] This embodiment of the invention pressurizes the air by setting up a pressurizing device, which drives the air supply device to rotate and generate air towards the object to be dried. This converts the mechanical energy of the pressurizing device into the mechanical energy of the air supply device, realizing the effective conversion and utilization of energy and improving the effectiveness of mechanical energy utilization.

[0073] In some possible implementations, the heating device 201 is a heating plate.

[0074] Optionally, the current temperature T1 of the heating plate is measured by the temperature measuring device 202. If the current temperature T1 reaches the set temperature T... a The temperature control device reduces the PWM duty cycle. If the current temperature T1 has not reached the set temperature T... a The temperature control device increases the PWM duty cycle, causing the heating plate temperature T1 to rise to the set temperature T. a This effectively stabilizes the temperature of the heating plate at T. a .

[0075] This embodiment of the invention uses a heating plate as a heating device, which can improve heating efficiency, shorten heating time, and enhance drying effect.

[0076] In some possible implementations, the temperature control switch 203 is a silicon controlled rectifier (SCR).

[0077] This embodiment of the invention uses a silicon controlled rectifier (SCR) as a temperature control switch, which can control the heating degree of the heating device by controlling the opening and closing degree of the SCR, thereby enhancing the controllability of the drying effect, improving the accuracy of controlling the drying air temperature, and saving energy.
