Description

Technical Field

[0001] The invention relates to the technical field of dehumidifiers, and in particular to a dehumidifier water tank. Background Art

[0002] A dehumidifier is a household appliance, which can be divided into household dehumidifiers and industrial dehumidifiers. It is composed of a compressor, a heat exchanger, a fan, a water tank, a casing and a controller. Its main purpose is to reduce the humidity in the space. Its working principle is: the fan draws humid air into the machine, and the water molecules in the humid air are condensed into water droplets through the heat exchanger. The dry air after heat exchange is discharged out of the machine. This cycle keeps the indoor humidity at a suitable relative humidity.

[0003] Existing dehumidifiers generally discharge condensed water into their own water tanks or directly to the outside of the machine body by direct drainage. When the condensed water is discharged into the water tank, the water needs to be poured out after the water tank is full and then reinserted into the water tank for the machine to work, which requires manual supervision and regular drainage. When the condensed water is discharged to the outside of the machine body, you can generally choose to discharge it directly into the sewer or into an external container. If you choose to discharge it directly into the sewer, since the distance of the direct drainage pipe of the dehumidifier is relatively short, it needs to be installed and used near the sewer to achieve continuous drainage without manual supervision, which has a relatively large location restriction; if you choose to discharge it into an external container, since the use of an external container is also limited by the volume of the container itself, it also requires manual supervision and regular drainage, which is relatively inconvenient. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a dehumidifier water tank, which can achieve continuous and automatic drainage without the need for manual supervision, without distance restrictions, and is easy to use.

[0005] The present invention is achieved through the following technical solutions:

[0006] A dehumidifier water tank, comprising:

[0007] The water tank body includes a water inlet and a drainage interface, the water inlet is connected to the drainage outlet of the dehumidifier, and the drainage interface is externally connected to a drainage pipe; a water storage tank is arranged in the water tank body, and the water storage tank is connected to the water inlet for receiving water discharged when the dehumidifier is working;

[0008] A water pump is installed in the water tank body, and the water inlet of the water pump is connected to the water storage tank, and the water outlet of the water pump is connected to the drainage interface;

[0009] At least one float switch, which is installed in the water tank and includes a float. When the float is at a preset high position, the float switch triggers a high position signal, and when the float is at a preset low position, the float switch triggers a low position signal;

[0010] The electric control board is connected to the water pump and the float switch signal at the same time;

[0011] When the dehumidifier drains water into the water tank, the float rises with the water level. When the float reaches the preset high position, the float switch triggers a high position signal and sends a signal to the electronic control board. The electronic control board controls the water pump to start pumping water. The float drops with the water level. When the float reaches the preset low position, the float switch triggers a low position signal and sends a signal to the electronic control board. The electronic control board controls the water pump to stop pumping water.

[0012] Furthermore, the float switch is installed on the side wall of the water tank, and the float switch is arranged away from the water inlet.

[0013] Furthermore, the at least one float switch includes a pair of float switches, and the pair of float switches are arranged in a vertical direction.

[0014] Furthermore, a power source is integrated in the water tank body, and a socket connected to the power source is also provided on the water tank body, and the socket is connected to the plug of the dehumidifier.

[0015] Furthermore, a partition is arranged in the water tank body, the partition is arranged above the water tank, and the water pump, the electric control board, the power supply and the socket are all arranged on the side of the partition away from the water tank.

[0016] Furthermore, a water inlet of the water pump is connected to a water suction pipe, and the water suction port of the water suction pipe is not higher than a preset low position of a float switch located below.

[0017] Furthermore, a pair of probes are installed on the partition, and the pair of probes are electrically connected to the electric control board. When the water level in the water tank submerges the pair of probes, the pair of probes are turned on and send signals to the electric control board to stop supplying power to the dehumidifier.

[0018] Furthermore, a floating component is also provided in the water tank body, and the floating component includes a floating part, a magnetic switch and a rotating shaft. The magnetic switch and the rotating shaft are both provided on the side of the partition facing the water tank, and the magnetic ring switch is electrically connected to the electric control board. The floating part can rotate around the rotating shaft, and the floating part includes a first position and a second position. When the floating part rotates to the second position, the floating part abuts against the magnetic switch and triggers the magnetic switch to turn on, and the magnetic ring switch sends a signal to the electric control board to stop supplying power to the dehumidifier.

[0019] Furthermore, an inclined surface is formed at the bottom of the floating member. When the water level rises, the inclined surface rotates from the first position to the second position around the rotation axis under the push of the water surface.

[0020] Further, the lower edge of the probe is higher than a preset high position of the float switch located above, and when the water level rises to the lower edge of the probe, the floating member is located between the first position and the second position.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] 1. By using the electric control panel to receive the high and low position signals of the float switch to control the start and stop of the water pump, automatic and continuous drainage can be achieved without manual supervision.

[0023] 2. By connecting a drainage pipe to the drainage interface, and the length of the drainage pipe can be adjusted according to specific needs, the drainage is not limited by distance.

[0024] 3. By setting up a pair of probes and floating components as double protection for the dehumidifier water tank, when the float switch fails, it can effectively avoid the safety hazard of overflowing due to excessive water level caused by continuous drainage, causing the live components to be soaked in water.

Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and cannot be understood as limitations on the present invention.

[0033] like Figure 1 As shown, a dehumidifier water tank according to an embodiment of the present invention comprises a water tank body 1, a water pump 2, at least one float switch 3 and an electric control board 7. The water tank body 1 comprises a water inlet 11 and a drainage interface 12, the water inlet 11 is connected to the drainage port of the dehumidifier, and the drainage interface 12 is externally connected to a drainage pipe. A water storage tank 13 is arranged in the water tank body 1, and the water storage tank 13 is connected to the water inlet 11 for receiving water discharged when the dehumidifier is working. The water pump 2 is installed in the water tank body 1, and the water inlet of the water pump 2 is connected to the water storage tank 13, and the water outlet of the water pump 2 is connected to the drainage interface 12. The float switch 3 is installed in the water storage tank 13, and the float switch 3 comprises a float 31. When the float 31 is at a preset high position, the float switch 3 triggers a high position signal, and when the float 31 is at a preset low position, the float switch 3 triggers a low position signal. The electric control board 7 is simultaneously connected to the water pump 2 and the float switch 3 signals. When the dehumidifier drains water into the water tank 13, the float 31 rises with the water level. When the float 31 reaches the preset high position, the float switch 3 triggers a high position signal and sends a signal to the electric control board 7. The electric control board 7 controls the water pump 2 to start pumping water. The float 31 drops with the water level. When the float 31 reaches the preset low position, the float switch 3 triggers a low position signal and sends a signal to the electric control board 7. The electric control board 7 controls the water pump 2 to stop pumping water. By using the electric control board 7 to receive the high and low position signals of the float switch 3 to control the start and stop of the water pump 2, automatic continuous drainage is achieved without manual supervision. An external drainage pipe is connected at the drainage interface 12, and the length of the drainage pipe can be adjusted according to specific needs, so that the drainage is not limited by distance.

[0034] like Figure 2As shown, a power supply is integrated in the water tank body 1, and a socket 6 connected to the power supply is also provided on the water tank body 1. The power supply supplies power to the dehumidifier by connecting the socket 6 to the plug of the dehumidifier, and the electric control board 7 can control the on and off of the power supply.

[0035] Further, such as Figure 3 As shown, a partition 15 is provided in the water tank body 1, and the partition 15 is provided above the water tank 13, and the water pump 2, the electric control board 7, the power supply and the socket 6 are all provided on the side of the partition 15 away from the water tank 13, so as to avoid the situation that the live components are soaked due to water leakage or the continuous rise of the water level, thereby causing a safety hazard. By providing the partition 15 to separate the water pump 2, the electric control board 7, the power supply and the socket 6 from the water tank 13, it can effectively prevent the water from splashing onto the live components when water enters, thereby damaging the components and causing a safety hazard.

[0036] Furthermore, the water inlet of the water pump 2 is connected to a water suction pipe 14, and the water suction port 141 of the water suction pipe 14 is not higher than a preset low position of the float switch 3 located below.

[0037] like Figure 3 and Figure 4 As shown, the float switch 3 is installed on the side wall of the water tank 13, and the float switch 3 is set away from the water inlet 11. Specifically, a first bracket 34 is fixedly connected to the side wall of the water tank 13, and the float switch 3 is fixed on the first bracket 34. By using the first bracket 34 to fix the float switch 3 on the side wall of the water tank 13, it is prevented that the float switch 3 loses balance in the water during drainage and floats, thereby affecting the detection effect. By setting the float switch 3 away from the water inlet 11, water flow interference can be reduced and the detection effect can be improved.

[0038] In order to increase the water level travel of the water tank 13, in this embodiment, the number of at least one float switch 3 is set to a pair, and the pair of float switches 3 is arranged in the vertical direction. It is worth noting that in other embodiments, the number of at least one float switch 3 can also be set to one or more, and the specific number can be selected and set according to the height of the water tank 13 selected by the user.

[0039] Furthermore, when the dehumidifier drains water into the water storage tank 13, the float 31 rises with the water level. When and only when both floats 31 reach the preset high position, that is, when both float switches 3 trigger the high position signal, the electric control board 7 receives the two high position signals and controls the water pump 2 to start pumping water, and the float 31 drops with the water level. When and only when both floats 31 reach the preset low position, that is, when both float switches 3 trigger the low position signal, the electric control board 7 receives the two low position signals and controls the water pump 2 to stop pumping water.

[0040] Specifically, when one of the two float switches 3 fails or fails at the same time, the water pump 2 will no longer work. Specifically, when the upper float switch 3 fails, the electric control board 7 cannot receive the high-level signal of the upper float switch 3, and the water pump 2 cannot start pumping water; when the lower float switch 3 fails, the water pump 2 is in the pumping state. Since the electric control board 7 integrates the delay control program of the water pump 2, when the pumping time of the water pump 2 exceeds the preset value, the water pump 2 stops working and will not start again, so as to prevent dry pumping and increase the service life of the water pump 2.

[0041] Further references Figure 5 A pair of probes 5 electrically connected to the electric control board 7 are installed on the partition 15, and the lower edge of the probes 5 is higher than the preset high position of the float switch 3 located above.

[0042] In the embodiment, the probes 5 serve as the first level of protection. When one of the two float switches 3 fails or fails at the same time, the water pump 2 no longer works, the dehumidifier is still in a drainage state, and the water level in the water tank 13 continues to rise. When the water level in the water tank 13 submerges a pair of probes 5, the pair of probes 5 is turned on and sends a signal to the electrical control board 7 to stop supplying power to the dehumidifier, effectively avoiding the safety hazard of overflowing due to excessive water level caused by continuous drainage, causing the live components to be soaked in water.

[0043] Further references Figure 6 A floating assembly 4 is also provided in the water tank body 1. The floating assembly 4 includes a floating member 41, a magnetic switch 42 and a rotating shaft 43. The magnetic switch 42 and the rotating shaft 43 are both provided on the side of the partition 15 facing the water tank 13, and the magnetic switch 42 is electrically connected to the electric control board 7. The floating member 41 can rotate around the rotating shaft 43.

[0044] The floating member 41 includes a first position and a second position. When the water level rises to the lower edge of the probe 5 , the floating member 41 is located between the first position and the second position.

[0045] The bottom of the floating member 41 is formed with an inclined surface 411 . When the water level rises, the inclined surface 411 rotates from the first position to the second position around the rotating shaft 42 under the push of the water surface.

[0046] In this embodiment, the floating component 4 serves as the second level of protection. If the probe 5 fails, the water level in the water tank 13 continues to rise. When the floating component 41 rotates to the second position, the floating component 41 abuts against the magnetic switch 42 and triggers the magnetic switch 42 to turn on. The magnetic ring switch sends a signal to the electrical control board 7 to stop supplying power to the dehumidifier, effectively avoiding the safety hazard of overflowing due to excessive water level caused by continuous drainage, which causes the live components to be soaked in water.

[0047] By providing a pair of probes 5 and a floating assembly 4 as double protection for the dehumidifier water tank, when the float switch 3 fails, the potential safety hazard of overflowing due to excessive water level caused by continuous drainage, which may cause live components to be soaked in water, can be effectively avoided.

[0048] A dehumidifier water tank according to an embodiment of the present invention controls the start and stop of the water pump 2 by using the electric control board 7 to receive the high and low position signals of the float switch 3, and realizes automatic continuous drainage without manual supervision. By connecting a drainage pipe externally at the drainage interface 12, and the length of the drainage pipe can be adjusted according to specific needs, the effect of drainage without distance restriction is achieved. By arranging a pair of float switches 3 in the vertical direction, the water level stroke of the water storage tank 13 is increased. By arranging a pair of probes 5 and a floating assembly 4 as double protection for the dehumidifier water tank, when the float switch 3 fails, the safety hazard of overflowing due to excessive water level caused by continuous drainage, which causes the live components to be soaked in water, can be effectively avoided. By arranging the float switch 3 away from the water inlet 11, the interference of water flow can be reduced and the detection effect can be improved. By integrating the delay control program of the water pump 2 in the electric control board 7, when the pumping time of the water pump 2 exceeds the preset value, the water pump 2 is automatically controlled to stop working to prevent dry pumping and increase the service life of the water pump 2.

[0049] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
