[0031] This application provides an evaporator cleaning device and a clothing treatment equipment to solve the problem that existing dryer evaporators create a high-humidity environment due to the interception of lint and condensate, which easily breeds bacteria and produces odors. The following description is in conjunction with the accompanying drawings.

[0032] The evaporator 7 cleaning device provided in this application embodiment is suitable for clothing processing equipment. The clothing processing equipment includes an evaporator 7, and the evaporator 7 cleaning device includes a liquid storage box 1 and a spray assembly 2. Please refer to... Figure 1 The liquid storage box 1 is detachably installed on the clothing processing equipment and is used to store the disinfectant liquid; the spray assembly 2 is installed on the clothing processing equipment and is located on the periphery of the evaporator 7. The spray assembly 2 is connected to the liquid storage box 1 and has a number of spray holes. The spray holes are used to spray the evaporator 7 after the clothing processing equipment has finished drying.

[0033] The evaporator 7 cleaning device provided in this embodiment provides disinfectant to the spray assembly 2 through the liquid storage box 1. After the drying process of the garment processing equipment is completed, the spray assembly 2 sprays disinfectant onto the evaporator 7. This not only washes away accumulated lint, fuzz, and other impurities on the evaporator 7, but also eliminates bacteria on the surface of the evaporator 7, achieving a sterilization and deodorization effect. This prevents bacteria from multiplying for a long time in the high-humidity environment on the surface of the evaporator 7, which could lead to odor growth and contaminate the entire garment processing equipment, affecting the cleaning or drying effect. Furthermore, the liquid storage box 1 is removable, allowing users to easily replace the liquid storage box 1 or add disinfectant when it runs out.

[0034] Optionally, the evaporator 7 cleaning device provided in this application embodiment further includes a humidity sensor 3. The humidity sensor 3 is disposed on the evaporator 7 and is used to detect the humidity of the evaporator 7. The humidity sensor 3 is communicatively connected to the spray assembly 2. When the detection result of the humidity sensor 3 is greater than the preset humidity value, the spray assembly 2 sprays the evaporator 7.

[0035] Optionally, the spray assembly 2 can be located on top of the evaporator 7.

[0036] Since bacteria multiply more frequently and at a higher rate when the surface humidity of the evaporator 7 is high, a humidity sensor 3 is installed on the surface of the evaporator 7 to monitor the humidity value. When the detection result of the humidity sensor 3 is greater than the preset humidity value, the spray assembly 2 is turned on to spray the evaporator 7 for cleaning and maintenance. It should be noted that the humidity sensor 3 is turned on and monitors the humidity of the evaporator 7 surface only after the clothes processing equipment has finished drying, so as to avoid spraying the evaporator 7 during the drying process of the clothes processing equipment, which would affect the drying effect of the clothes processing equipment.

[0037] In some examples, the preset humidity value can be 80% RH.

[0038] Optionally, the evaporator 7 cleaning device provided in this application embodiment further includes an odor sensor 4, which is installed on the evaporator 7 and used to detect the concentration of odor gas; the odor sensor 4 is communicatively connected to the spray assembly 2, and when the detection result of the odor sensor 4 is greater than the preset concentration, the spray assembly 2 sprays the evaporator 7.

[0039] Among them, the odor sensor 4 is an electronic device used to detect, identify, and measure volatile organic compounds (VOCs), malodorous gases, or other odorous substances in the air. The odor sensor 4 is typically based on the following technologies: Metal-Oxide-Semiconductor (MOS): The resistance of the sensitive material (such as SnO2, ZnO) changes when it comes into contact with odorous gases, and this change is converted into an electrical signal by a circuit. Alternatively, an electrochemical sensor: Detects specific gases (such as H2S, NH3) by generating current through a chemical reaction between the gas and an electrolyte. Alternatively, a photoionization detector (PID): Detects VOCs by measuring the ion current using ultraviolet light to ionize gas molecules. Alternatively, a biosensor: Simulates biological olfaction (such as a bionic electronic nose), generating a signal through the binding of biological materials with gas molecules. Alternatively, infrared / spectroscopy: Identifies components by the absorption of specific wavelengths of light by gas molecules.

[0040] By setting the odor sensor 4, the gas around the evaporator 7 can be accurately monitored. When the concentration of odor gas around the evaporator 7 is greater than the preset concentration, the spray assembly 2 is controlled to spray the evaporator 7 to improve the accuracy of odor monitoring around the evaporator 7, prevent bacteria on the evaporator 7 from further multiplying and producing odor, and affect the drying effect of the load.

[0041] In some examples, the preset concentration can be 500 ppb.

[0042] Optionally, the evaporator 7 cleaning device provided in this application embodiment further includes a booster pump 5, connected to the liquid storage box 1 and the spray assembly 2. The booster pump 5 is used to pump the sterilizing solution in the liquid storage box 1 to the spray assembly 2. By setting the booster pump 5, the spray speed and pressure of the spray assembly 2 are increased, achieving a greater impact force on the surface of the evaporator 7, thereby improving the cleaning effect. The type of booster pump 5 is not further limited here.

[0043] Optionally, a check valve is provided in the liquid storage box 1. By providing the check valve, the sterilization solution in the spray assembly 2 is prevented from flowing back into the liquid storage box 1.

[0044] As is understandable, a check valve (also known as a one-way valve or non-return valve) is a mechanical device used to prevent the reverse flow of fluids (gas or liquid), ensuring that the medium can only pass in one direction. A check valve achieves unidirectional flow through the automatic opening and closing of a valve disc (or valve core): fluid pressure pushes the valve disc open; when the fluid pressure disappears or reverses, the valve disc closes under gravity, spring force, or medium pressure, blocking backflow. No further limitations are made on the types of check valves here.

[0045] Optionally, the evaporator 7 cleaning device provided in this application embodiment further includes a water receiving tray 6, which is disposed at the bottom of the evaporator 7 and is used to collect water from the surface of the evaporator 7. By providing a water receiving tray 6 at the bottom of the evaporator 7 to collect the condensate on the surface of the evaporator 7 and the disinfecting solution used to clean the evaporator 7, water is prevented from flowing inside the clothing processing equipment and affecting its operation.

[0046] Optionally, a filter disc is installed inside the water receiving tray 6 to filter impurities. By installing a filter disc inside the water receiving tray 6, impurities such as lint and fuzz that fall off after cleaning the surface of the evaporator 7 are filtered out, preventing impurities from clogging the drain pipe when discharged with water and ensuring that the drain pipe can drain normally.

[0047] The shape and size of the filter are not further limited here; they can be selected according to the specific circumstances.

[0048] Optionally, the disinfectant solution includes fragrance substances. By adding fragrance substances to the disinfectant solution, the scent within the garment processing equipment can be enhanced, increasing user satisfaction with the equipment. These fragrance substances can include a variety of scents, such as floral, fruity, woody, spicy, or marine fragrances, allowing users to add the appropriate type according to their preferences.

[0049] Optionally, the garment processing equipment is equipped with an alarm module. A liquid level sensor is installed in the liquid storage box 1, and the liquid level sensor is communicatively connected to the alarm module. When the liquid level sensor detects a level below a preset level, the alarm module sounds an alarm. By setting the liquid level sensor, the liquid level of the disinfectant in the liquid storage box 1 is monitored, and an alarm is triggered promptly when the disinfectant is insufficient, reminding the user to replace the liquid storage box 1 or add disinfectant in a timely manner. The alarm method of the alarm module is not further limited here; in some examples, it can be a vibration alarm; in others, a light alarm; and in still others, an audible alarm.

[0050] Optionally, the spray assembly 2 can be turned on with a default preset spray duration, such as 8 minutes or 10 minutes. As an alternative implementation, the spray duration of the spray assembly 2 can be adjusted according to the detection results of the humidity sensor 3 or the odor sensor 4.

[0051] This application embodiment also provides a garment processing device, including an evaporator 7 and an evaporator 7 cleaning device as described above. The evaporator 7 cleaning device includes a liquid storage box 1 and a spray assembly 2. The liquid storage box 1 is detachably installed in the garment processing device and is used to store a disinfectant solution; the spray assembly 2 is installed in the garment processing device and located around the evaporator 7, the spray assembly 2 is connected to the liquid storage box 1, and the spray assembly 2 has a plurality of spray holes for spraying the evaporator 7 after the garment processing device has finished drying.

[0052] The type of garment processing equipment is not further limited here; for some examples, please refer to [link to relevant documentation]. Figure 2 It can be a dryer; in other examples, it can be a washing machine; in still other examples, please refer to Figure 3 It can be a washer-dryer combo.

[0053] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application.
