[0034] The present invention provides a dehumidifier.
[0035] Referring to Figures 1 to 3 , in an embodiment of the present invention, the dehumidifier includes:
[0036] A body 1;
[0037] A water tank 2, provided on the body 1; and
[0038] A non-contact water level sensor 3, located above the water tank 2 and used to detect the water level in the water tank 2.
[0039] The technical solution of the present invention is to provide a non-contact water level sensor 3 above the water tank 2 to detect the water level in the water tank 2 through the non-contact water level sensor 3; since the adopted water level sensor is non-contact, it does not need to be arranged below the water level of the water tank 2. Thus, even if the water tank 2 becomes dirty and accumulates dirt during long-term use, there will be no problem that the water level sensor cannot detect the water level due to scale accumulation, and it has a long service life, is durable and reliable, thereby improving the reliability of the water level detection function of the water tank 2 of the dehumidifier.
[0040] In this embodiment, generally, the upper end of the water tank 2 is provided with an open mouth, so as to facilitate the setting of the non-contact water level sensor 3; it can be understood that in this case, the non-contact water level sensor 3 can be set at any position above the water tank 2. Of course, in other embodiments, the upper end of the water tank 2 may not be provided with an open mouth, but at least a signal through hole for the detection signal of the non-contact water level sensor 3 to pass through needs to be provided at its upper end.
[0041] Furthermore, the lower part of the body 1 is provided with a mounting groove 10 with a lateral opening, the water tank 2 is embedded in the mounting groove 10, and the non-contact water level sensor 3 is installed on the upper groove wall 11 of the mounting groove 10. It can be understood that in this embodiment, the dehumidification device 6 of the dehumidifier is installed on the upper part of the body 1, and the water generated during the dehumidification process will flow into the water tank 2. In this embodiment, by installing the non-contact water level sensor 3 on the upper groove wall 11, when the water tank 2 is taken out from the mounting groove 10 to pour water, the non-contact water level sensor 3 will not be taken out together, and there is no need to deal with the problem of connecting wires between the non-contact water level sensor 3 and the body 1. However, the design is not limited to this. In other embodiments, the body 1 and the water tank 2 can also be arranged in upper and lower parts, that is, the water tank 2 is not embedded in the lower side of the body 1, but the upper end of the water tank 2 is connected to the lower end of the body 1. In this case, the non-contact water level sensor 3 is usually directly installed on the lower end surface of the body 1.
[0042] Furthermore, the non-contact water level sensor 3 is installed on the side of the upper groove wall 11 away from the installation groove 10, and the upper groove wall 11 is provided with a detection through hole 111 for the detection signal of the non-contact water level sensor 3 to pass through. In this embodiment, the non-contact water level sensor 3 is installed on the side of the upper groove wall 11 away from the installation groove 10, and the upper groove wall 11 can be used to provide physical protection for the non-contact water level sensor 3. It can be understood that if the non-contact water level sensor 3 uses the same detection head for receiving and sending signals, then only one detection through hole 111 needs to be opened (see Figure 2 ), for example, when it is a laser water level sensor; if the non-contact water level sensor 3 receives and sends signals using a detection head, the detection through hole 111 has two (see Figure 4 ), for example, when it is an ultrasonic water level sensor.
[0043] Furthermore, a protective isolation wall 12 is disposed above the upper tank wall 11, and the non-contact water level sensor 3 is located between the protective isolation wall 12 and the upper tank wall 11. It can be understood that the protective isolation wall 12 can isolate the non-contact water level sensor 3 from other components in the fuselage 1, and can provide better physical protection for the non-contact water level sensor 3; in particular, when other components in the fuselage 1 are repaired or replaced, the probability of touching the non-contact water level sensor 3 can be reduced, thereby reducing the probability of damage to the non-contact water level sensor 3.
[0044] Furthermore, the non-contact water level sensor 3 is detachably connected to the upper tank wall 11; thus, the non-contact water level sensor 3 can be easily disassembled and assembled, thereby facilitating its maintenance or replacement.
[0045] Optionally, a buckle position 112 is provided on the upper groove wall 11, and the non-contact water level sensor 3 is buckled on the buckle position 112. It can be understood that the buckle connection method is convenient for disassembly and assembly, and the non-contact water level sensor 3 and the upper groove wall 11 can be disassembled and assembled without using additional tools (such as screwdrivers, etc.). However, the present design is not limited to this. In other embodiments, the non-contact water level sensor 3 can also be connected to the upper groove wall 11 in a detachable manner such as screw locking, but is not limited to it.
[0046] In this embodiment, further optionally, the buckle position 112 is a pair of undercuts convexly provided on the upper groove wall 11, and the pair of undercuts are respectively buckled on opposite sides of the non-contact water level sensor 3. Of course, in other embodiments, the buckle position 112 can also be a buckle hole provided on the upper groove wall 11, and the non-contact water level sensor 3 is provided with a buckle that can be adapted to buckle into the buckle hole.
[0047] Furthermore, the non-contact water level sensor 3 includes a sensor body and a packaging box, and the sensor body is packaged in the packaging box, so that the packaging box provides physical protection for the sensor body, so as to extend the service life of the non-contact water level sensor 3. Of course, the detection head of the non-contact water level sensor 3 will be inserted into the packaging box; or, the packaging box is provided with an avoidance through hole for receiving and sending detection signals. In this embodiment, a pair of undercuts on the upper groove wall 11 are respectively buckled on opposite sides of the packaging box.
[0048] Reference Figure 5 , further, the dehumidifier also includes a display device 4, which is electrically connected to the non-contact water level sensor 3 and is used to display the detection result of the non-contact water level sensor 3, so that the user can know the detection result and control the working state of the dehumidifier according to the detection result. Usually, the display device 4 is arranged on the fuselage 1. Optionally, the display device 4 includes a display screen and / or a display light. When the display device 4 includes a display screen, the display screen can be optionally a touch screen, so that not only the detection result can be displayed on the display screen, but also the dehumidifier can be touch-controlled through the display screen. In this embodiment, the detection result includes the water level value, whether the water tank is installed, whether it does not exceed the minimum water level, and whether the maximum water level is reached. In particular, when the detected water level value is not less than zero, it can be determined that "the water tank is installed", and when the detected water level is less than zero, it can be determined that "the water tank is not installed".
[0049] Furthermore, the display device 4 can also display an alarm according to the detection result to remind the user to pay attention to the relevant status of the water tank 2; for example, but not limited to, the display device 4 can display an alarm when the detection result is "water tank not installed", "water level does not exceed the minimum water level", and "water level reaches the maximum water level", and the alarm display method includes displaying light or text flashing, displaying alarm symbols, displaying color changes, etc.
[0050] Furthermore, the dehumidifier further includes a controller 5, which is electrically connected to both the dehumidifying device 6 and the non-contact water level sensor 3 of the dehumidifier. The controller 5 is used to control the startup state of the dehumidifying device 6 according to the detection result. Generally, the controller 5 is arranged on the body 1. When the detection result is "the water tank is installed" and "the water level has not reached the highest water level", the controller 5 controls the dehumidifying device 6 to be turned on; when the detection result is "the water tank is not installed" or "the water level has reached the highest water level", the controller 5 controls the dehumidifying device 6 not to be turned on to prevent the condensed water from directly falling on the ground or overflowing onto the ground. In this embodiment, optionally, the dehumidifying device 6 includes a compressor, an evaporator and a condenser. First, the water vapor in the air is condensed into water droplets by the evaporator to remove the water vapor in the air, and then the air after removing the water vapor is heated and dried by the condenser to make the blown air return to room temperature; of course, in other embodiments, the dehumidifying device 6 can also adopt dehumidification methods such as adsorption type.
[0051] Furthermore, the dehumidifier further includes an alarm device 7, which is electrically connected to the controller 5. The controller 5 is also used to control the alarm device 7 to give an alarm prompt according to the detection result; in this way, the relevant alarm means of the dehumidifier can be enriched to better remind the user to pay attention to the relevant state of the water tank 2. Generally, the alarm device 7 is arranged on the body 1. Optionally, the controller 5 can control the alarm to give an alarm prompt when the detection result is "the water tank is not installed", "the water level does not exceed the lowest water level", and "the water level has reached the highest water level". The alarm can be a sound prompt device (such as a buzzer), a light prompt device, etc.
[0052] Furthermore, the dehumidifier further includes a drainage pump 8 to realize the automatic drainage of the water tank 2 through the drainage pump 8, thereby reducing the number of times of pouring water required for the water tank 2 and improving the convenience of using the dehumidifier. Generally, the drainage pump 8 can be a submersible pump arranged in the water tank 2 or a diaphragm pump arranged on the body 1. In this embodiment, the drainage pump 8 can be automatically controlled by the controller 5. Of course, it can also be manually controlled, that is, a button for controlling the start and stop of the drainage pump 8 can also be provided on the dehumidifier. To realize the automatic control of the drainage pump 8, the controller 5 is electrically connected to the drainage pump 8, and the controller 5 is also used to control the working state of the drainage pump 8 according to the detection result. Optionally, the controller 5 can control the drainage pump 8 to start when the detection result is "the water level has reached the highest water level" to automatically drain the water in the water tank 2; the controller 5 can also control the drainage pump 8 to stop draining when the detection result is "the water level does not exceed the lowest water level" to prevent the drainage pump 8 from idling and being damaged.
[0053] Further, the dehumidifier further includes a communication module 9. The non-contact water level sensor 3 is electrically connected to the communication module 9. The communication module 9 is used to communicate with an external terminal to send the detection result to the external terminal. In this embodiment, the communication module 9 can be directly connected to the non-contact water level sensor 3, or can be indirectly connected to the non-contact water level sensor 3 through the controller 5. By providing the communication module 9 on the dehumidifier in this technical solution, the user can learn about the relevant status of the water tank 2 through an application program on an external terminal such as a mobile phone, a tablet computer, or a computer. Optionally, the communication module 9 is a wireless communication module, so that the user can more conveniently learn about the relevant status of the water tank 2 through the external terminal; further optionally, the wireless communication module may include, but is not limited to, at least one of a WIFI module, a Bluetooth module, a 4G module, and a 5G module. Of course, in other embodiments, the communication module 9 can also adopt a wired communication module as long as the communication connection between it and the external terminal can be achieved.
