Description

TECHNICAL FIELD

[0001] The utility model relates to dehumidification technical field, especially a kind of dehumidifier. BACKGROUND

[0002] In modern life, air humidity has an important influence on people's life and work environment. High humidity not only makes people feel uncomfortable, but also can cause furniture, electrical appliances to be damaged by damp, breed mold and other problems, affect indoor air quality and human health. Therefore, as an important device for adjusting indoor humidity, dehumidifier is widely used in various places such as family, office, warehouse, etc.

[0003] In order to ensure the normal operation of dehumidifier and prevent water overflow in water tank from causing damage, dehumidifier is usually equipped with a float type water level sensor in the water tank. This sensor detects the change of water level by the up and down floating of float, when the water level reaches the preset height, the float triggers the sensor to send a signal to the control unit, so as to control the dehumidifier to stop working or start the drainage function, to prevent the water tank from being full.

[0004] However, in the actual long-term use process, as a long-term contact with water environment, water tank is easy to accumulate dirt, dust and other impurities. With the passage of time, these dirt may adhere to the float and its moving parts, causing the movement of float to be blocked or even stuck, and then making the float type water level sensor fail. Once the sensor fails, the dehumidifier cannot accurately detect the water level of the water tank, and the water may overflow, which not only causes damage to the use environment, but also may damage the dehumidifier itself, greatly affecting the reliability of dehumidifier water tank water level detection function and the normal use of dehumidifier.

[0033] The dehumidifier 10 according to an embodiment of the present application will be described below with reference to Figures 1 to 5 The dehumidifier 10 according to an embodiment of the present application will be described below with reference to

The illustrative appearances of the above terms in various places in the specification are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics can be combined in any suitable manner in one or more embodiments or examples.

[0036] The dehumidifier 10 according to an embodiment of the present application will be described below with reference to Figure 1 is a schematic structural view of the dehumidifier 10 according to an embodiment of the present application, Figure 2 is a schematic exploded view of the dehumidifier 10 according to an embodiment of the present application, Figure 3 is a schematic position view of the non-contact electric control sensor 120 according to an embodiment of the present application, Figure 4 is Figure 3 is an enlarged view of part A in Figure 5It is a schematic structural view of the non-contact electric control sensor 120 and the mounting plate 131 according to an embodiment of the utility model.

[0037] As shown in the figure, Figures 1 to 5 The dehumidifier 10 can generally include a casing 100, a water tank 110 and a non-contact electric control sensor 120.

[0038] The upper part of the front side, the upper part of the left side and the upper part of the right side of the casing 100 jointly enclose a wide air inlet 101, so that the indoor air can enter the casing 100 more smoothly, providing sufficient air source for the dehumidification process.

[0039] At the same time, the top of the casing 100 is formed with an air outlet 102, and the dry air treated by dehumidification can be uniformly released to the indoor space from the air outlet 102, and fully mixed and exchanged with the humid air in the room, thereby improving the dehumidification efficiency.

[0040] The water tank 110 is arranged in the casing 100. During the operation of the dehumidifier 10, the indoor humid air is sucked into the casing 100 through the air inlet 101, and after condensation treatment, dry air is blown out through the air outlet 102 at the top of the casing 100, thereby realizing effective reduction of indoor humidity. In this process, the humid air will condense into condensed water when it is cooled in the casing 100, and the water tank 110 serves as a collection container for the condensed water, which is used to safely and effectively store the condensed water.

[0041] The non-contact electric control sensor 120 is located outside the water tank 110 and is used to directly detect the water level in the water tank 110 through the side wall of the water tank 110. For example, the non-contact electric control sensor 120 in the embodiment is a capacitive water level sensor, and the "direct detection of the water level in the water tank 110" mentioned here is mainly based on the principle of electric field induction. When the water level in the water tank 110 changes, due to the difference in dielectric constant between water and surrounding air, the electric field formed between the sensor and the water in the water tank 110 will change, thereby causing the change of the sensor capacitance. This change in capacitance directly corresponds to the change in water level, without the need for auxiliary movement of other components to convert the signal.

[0042] Unlike the traditional dehumidifier 10 using a float type water level sensor, the dehumidifier 10 of the embodiment completely cancels the design of the float, and directly detects the water level in the water tank 110 by using the non-contact electric control sensor 120, thereby eliminating the hidden trouble caused by the jamming of the float due to dirt accumulation from the root, and significantly improving the reliability of the water level detection function.

[0043] In an optional embodiment, the casing 100 has a laterally open mounting groove 103, and the water tank 110 is inserted into the mounting groove 103, and the non-contact electric control sensor 120 is mounted on the groove wall opposite to the side wall of the water tank 110.

[0044] For example, the laterally open mounting groove 103 is formed at the lower part of the front side of the casing 100, and the non-contact electric control sensor 120 can be mounted on the left groove wall, the right groove wall or the rear groove wall of the mounting groove 103.

[0045] Since the water tank 110 is inserted into the mounting groove 103, the user can pull out the water tank 110 from the mounting groove 103, which is convenient for cleaning or draining the water tank 110 when needed, removing the dirt accumulated for a long time, ensuring the cleanliness of the water tank 110, and thus improving the overall operation effect of the dehumidifier 10.

[0046] The non-contact electric control sensor 120 is mounted on the groove wall opposite to the side wall of the water tank 110.

[0047] On the one hand, the non-contact electric control sensor 120 can maintain a better detection distance with the water tank 110, ensuring that the sensor can efficiently detect the water level through the side wall of the water tank 110.

[0048] On the other hand, in the case that the water tank 110 is pulled out, the non-contact electric control sensor 120 is still inside the casing 100, maintaining its powered state, solving the electrical connection problem that may occur in the traditional design, improving the user experience, and ensuring the stable operation of the equipment.

[0049] In addition, the non-contact electric control sensor 120 is mounted on the groove wall of the mounting groove 103, and the sensor is less affected by factors such as water flow fluctuation and condensate splashing in the water tank 110, further improving the stability and accuracy of detection.

[0050] In an optional embodiment, the non-contact electric control sensor 120 is mounted on the outside of the groove wall opposite to the groove opening of the mounting groove 103. That is, the non-contact electric control sensor 120 is mounted on the outside of the rear groove wall of the mounting groove 103.

[0051] This layout avoids the contact electric control sensor occupying additional space in the left-right direction of the casing 100, improves the utilization rate of the internal space of the casing 100, and is conducive to improving the integration and compactness of the whole machine.

[0052] Figure 3 The lower half structure of the dehumidifier 10 is shown, and the rear casing 100 is hidden to intuitively understand the setting position of the non-contact electric control sensor 120.

[0053] In addition, the non-contact electric sensor 120 is installed outside the rear groove wall of the installation groove 103, and the rear groove wall of the installation groove 103 can separate the non-contact electric sensor 120 from the water tank 110, thereby reducing the potential influence of the complex environment inside the installation groove 103 on the sensor. For example, the sensor is effectively prevented from being eroded by water vapor and moisture inside the installation groove 103 for a long time, thereby greatly prolonging the service life of the sensor and ensuring the long-term stable operation of the water level detection system of the dehumidifier 10.

[0054] In an optional embodiment, the outer side of the groove wall of the installation groove 103 can be provided with a mounting assembly 130 for fixing the non-contact electric sensor 120 and making the detection probe 121 horizontally face the inside of the water tank 110.

[0055] The detection probe 121 horizontally faces the inside of the water tank 110, which can minimize detection errors and enable the sensor to more effectively capture the capacitance change signal caused by the change of the water level in the water tank 110, thereby providing more accurate water level data for the control system of the dehumidifier 10 and ensuring the stable operation and efficient dehumidification of the dehumidifier 10.

[0056] In an optional embodiment, the mounting assembly 130 includes a mounting plate 131 serving as a basic bearing component of the non-contact electric sensor 120, and the mounting plate 131 is provided with a receiving groove 134, and the non-contact electric sensor 120 is embedded in the receiving groove 134 and makes the detection probe 121 of the non-contact electric sensor 120 extend out of the mounting plate 131 in the direction facing the water tank 110.

[0057] For example, the mounting plate 131 is vertically arranged, and the rear side of the mounting plate 131 is surrounded by a surrounding plate to form a receiving groove 134 extending in the front-rear direction, and the non-contact electric sensor 120 is inserted into the receiving groove 134 from the rear to the front, and the mounting plate 131 is provided with a gap corresponding to the position of the receiving groove 134, and the detection probe 121 of the non-contact electric sensor 120 extends out of the mounting plate 131 from the gap.

[0058] It can be understood that the non-contact electric sensor 120 is embedded in the receiving groove 134 of the mounting plate 131, and the receiving groove 134 provides a relatively closed and suitable installation space for the non-contact electric sensor 120, effectively preventing the direct intrusion of dust and sundries from the outside, avoiding the entry of these foreign matters into the inside of the sensor and affecting the normal work of the sensor. At the same time, the receiving groove 134 can also prevent other components from colliding with the non-contact electric sensor 120 and avoid damaging the non-contact electric sensor 120.

[0059] Since the detection probe 121 is horizontally oriented towards the inside of the water tank 110, the detection error can be minimized, enabling the sensor to more effectively capture the capacitance change signal caused by the water level change in the water tank 110, and further providing more accurate water level data for the control system of the dehumidifier 10, thereby ensuring stable operation and efficient dehumidification of the dehumidifier 10.

[0060] In an optional embodiment, the mounting assembly 130 can further comprise a first clamping member 132 arranged on the upper and lower sides of the mounting plate 131 for clamping and fixing the mounting plate 131 from the upper and lower sides of the mounting plate 131.

[0061] During the operation of the dehumidifier 10, a certain degree of vibration and shaking will occur inside the casing 100. If the mounting plate 131 is not firmly fixed, the position of the sensor may be shifted, thereby affecting the accuracy of water level detection. The first clamping member 132 can firmly fix the mounting plate 131 outside the groove wall of the mounting groove 103 through tight clamping, ensuring that the sensor can maintain a stable working state in any situation and providing continuous and reliable data support for water level detection.

[0062] Further, the mounting assembly 130 can further comprise a second clamping member 133 arranged on the left and right sides of the mounting plate 131 for clamping and fixing the mounting plate 131 from the left and right sides of the mounting plate 131.

[0063] This all-around clamping and fixing method fully constrains the mounting plate 131 in both horizontal and vertical directions, greatly improving the overall stability of the mounting plate 131 and the sensor. Whether during the transportation of the dehumidifier 10 or during long-term operation, the second clamping member 133 can effectively prevent the mounting plate 131 from shifting or shaking left and right, ensuring that the sensor is always in the best working position, thereby ensuring the reliability and stability of the water level detection function.

[0064] In an optional embodiment, the mounting plate 131 can be provided with a protrusion 135 extending towards the groove wall of the mounting groove 103, the protrusion 135 abutting against the groove wall of the mounting groove 103, for reserving a containing space between the mounting plate 131 and the groove wall of the mounting groove 103 to accommodate the detection probe 121.

[0065] When the mounting plate 131 is fixed to the groove wall of the mounting groove 103 by the first clamping member 132 and the second clamping member 133, due to the presence of the protrusion 135, the protrusion 135 can reserve a containing space between the mounting plate 131 and the groove wall of the mounting groove 103 to accommodate the detection probe 121, avoiding pressing the detection probe 121.

[0066] It can be understood that when the first buckle 132 clamps the mounting plate 131 from the upper and lower sides, and the second buckle 133 clamps the mounting plate 131 from the left and right sides, the protrusion 135 will abut the groove wall of the mounting groove 103, so that the mounting plate 131 and the groove wall of the mounting groove 103 leave a containing space for containing the detection probe 121, avoiding damage to the detection probe 121 due to extrusion between the mounting plate 131 and the groove wall during fixing the mounting plate 131, and comprehensively ensuring the safety of the detection probe 121, laying a solid foundation for the non-contact electric sensor 120 to stably and accurately detect the water level.

[0067] In an optional embodiment, the distance between the detection probe 121 of the non-contact electric sensor 120 and the upper edge of the water tank 110 can be 1 / 5 to 1 / 4 of the height of the water tank 110. For example, 1 / 5, 1 / 4, etc.

[0068] When the water level in the water tank 110 gradually rises and reaches the same height as the detection probe 121, based on the electric field induction principle of the sensor, the internal capacitance value will change significantly. This change will be quickly converted into an electrical signal and transmitted to the control system of the dehumidifier 10, triggering an alarm mechanism. The alarm can be presented in various intuitive ways, such as emitting a sharp buzzing sound, lighting a prominent warning light on the operation panel of the dehumidifier 10, or even sending a reminder message to the user's mobile phone through the linkage with the smart home system, ensuring that the user can be aware of the water level reaching the warning line in the water tank 110 in time.

[0069] Controlling the distance between the detection probe 121 and the upper edge of the water tank 110 within this specific range has important practical significance.

[0070] On the one hand, it can effectively prevent the user from not draining in time after the water level reaches, causing the water tank 110 to overflow. Water overflow not only may damage the dehumidifier 10 itself, but also may cause damage to surrounding furniture, floor, etc., causing unnecessary economic losses.

[0071] On the other hand, if the detection probe 121 is set too low, the water level in the water tank 110 will trigger an alarm signal even slightly rising, which will cause frequent drainage. Frequent drainage not only increases energy consumption, but also may interfere with the normal operation rhythm of the dehumidifier 10, reducing the user's experience.

[0072] The utility model precisely controls the position of the detection probe 121, which balances the two aspects appropriately, realizes efficient, stable and intelligent water level monitoring and alarm function, and provides more reliable and convenient dehumidification experience for users.

[0073] In the above embodiments, the non-contact electric sensor 120 is mainly described with a single probe, aiming to clearly present its working principle and installation advantages. However, in actual application, the number of detection probes 121 of the non-contact electric sensor 120 is not fixed.

[0074] For example, when a double-probe design is adopted, the non-contact electric sensor 120 is composed of a low-level probe and a high-level probe. The low-level probe can give an early warning prompt to inform the user that the water level of the water tank 110 is rising and will soon reach the drainage water level; and the high-level probe serves as a secondary alarm prompt to issue a more urgent alarm when the water level continuously rises to the position of the high-level probe, reminding the user to handle it in time to prevent water from overflowing.

[0075] For another example, when a three-probe design is adopted, the non-contact electric sensor 120 is composed of a low-level probe, a middle-level probe and a high-level probe. The low-level probe still undertakes the task of pre-alarm prompt, the middle-level probe is responsible for secondary alarm prompt to further remind the user to pay attention to the water level change. The high-level probe is used to play a backup alarm role. Once the low-level probe and the middle-level probe appear abnormal conditions such as damage, once the water level rises to the high-level probe, the high-level probe will respond in time to give an alarm prompt, ensuring the reliability of the water level detection and alarm function, avoiding the water level monitoring blind area caused by the failure of the detection probe 121, and fully guaranteeing the safe and stable operation of the dehumidifier 10.

[0076] The non-contact electric sensor 120 adopted by the utility model has unique working characteristics and wide applicability. Its working principle is based on advanced electric field induction technology. When the electric field near the detection probe 121 changes due to the presence of liquid, the sensor can quickly sense this change and convert it into a switch signal output. This signal output method is simple and direct, easy to integrate with various control systems, and provides convenience for the automatic control of equipment. At the same time, the detection process of the sensor is completely non-contact, avoiding the corrosion and wear problems that may be caused by the direct contact of traditional contact sensors with liquid, greatly improving the service life and safety and reliability of the sensor.

[0077] In terms of application scope, the non-contact electric sensor 120 also shows strong compatibility. It is applicable to any non-metallic material, whether it is common plastic, glass or other new composite materials. As long as the total thickness of the side wall of the water tank 110 and the side wall of the installation groove 103 is not more than 20 mm, accurate detection can be achieved. This feature enables the sensor to be widely used in various types of dehumidifier 10 water tank 110 design, providing strong support for the diversified development of products.

[0078] It should be noted that the liquid to be detected must be an electrically conductive solution, which is determined by the electric field sensing principle of the sensor. Only when the liquid can conduct electricity, can an effective electric field change be formed between the sensor and the liquid, so as to realize accurate detection. Generally, the condensed water generated by the dehumidifier 10 can conduct electricity. When the water condensed from the air during the operation of the dehumidifier 10, some impurities in the air, such as carbon dioxide, sulfur dioxide and a small amount of dust particles, are dissolved in the water during the formation process. Although the content of these impurities is relatively small, they can ionize in water to produce free-moving ions, thereby making the condensed water have certain electrical conductivity.

[0079] In addition, in order to ensure the normal operation and stable performance of the sensor, the temperature in the container cannot exceed 100℃. High temperature may affect the performance of the internal electronic components of the sensor, and even cause damage to the components, thereby affecting the reliability of the entire water level detection system. By reasonably limiting the working conditions, the non-contact electric control sensor 120 of the embodiment can ensure the detection accuracy and reliability while realizing stable operation in various complex application scenarios, thereby providing a solid technical guarantee for the intelligent development of the dehumidifier 10 and other related equipment.

[0080] At this point, those skilled in the art should realize that although the present application has been shown and described in detail in the above embodiments, many other variants or modifications in accordance with the principles of the present application can be directly determined or deduced based on the disclosure of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and recognized as covering all these other variants or modifications.
