According to an embodiment of the present invention, there is also provided a clothes dryer, the clothes dryer has the above water storage box, the clothes dryer has the above water storage box, when the water level detection sensor detects that the water level in the water storage box reaches the preset When the water level is reached, the water level detection sensor transmits a detection signal to the clothes dryer, and the clothes dryer stops working.

In order to better understand the above-mentioned technical solution of the present invention, the above-mentioned technical solution of the present invention will be described in detail below with a specific example of a clothes dryer.

As shown in Figure 1-6, the clothes dryer includes a box body 12, a door body 13, a control panel 14, a water box assembly (including box body 1 and water box 4 and related components) 15, a drum 16, a fan 17, a condenser Water storage tank 18, condenser 19, fan two 20, heater 21, drain pipe 22, overflow pipe 23.

The working process of the clothes dryer is: the user opens the door body 13 of the clothes dryer, puts clothes into the drum 16, selects a program, and starts the clothes dryer. The fan two 20 drives the air in the bucket to circulate, and the heater 21 heats the air to enter the bucket to dry clothes, and then becomes hot and humid air to flow out of the bucket through the filter screen from the bottom of the door body 13, and passes through the condenser 19. At this time, the fan one 17 The cold air inhaled from the outside also passes through the condenser 19 to condense the humid and hot circulating air, and the water vapor in the circulating air is condensed into water and stored in the condensed water storage tank 18 below, and then the condensed water is pumped (not shown) Into the water box assembly 15 above the clothes dryer. And the circulating air becomes the low-temperature dry air, and the next circulation is carried out after being heated by the heater 21.

During the drying process, the water box 4 completely enters the water box accommodating cavity 2 (as shown in Figure 2), and after the hot and humid circulating air passes through the condenser 19, the moisture in the air is condensed to form condensed water, which flows into the condensed water In the water storage tank 18 , the condensed water in the condensed water storage tank 18 can be extracted by a water pump (not shown), and enter the water box 4 through the drain pipe 22 through the water inlet 5 on the water box 4 . At this time, because the water box 4 has completely entered the water box accommodation chamber 2, the water level detection channel 7 in the water box accommodation chamber 2 pushes away the baffle plate 9 on the side wall of the water box 4, and communicates with the water level detection port 6 on the water box 4, In this way, the water level in the water level detection channel 7 is the same as the water level in the water box 4, and the capacitive water level sensor (water level detection sensor 8) is located in the water level detection channel 7, so the water level of the water box 4 can be measured. A water level H ₀ is preset in the program. When the water level of the water box is higher than H ₀ , the water will overflow into the chamber 2 of the water box, and enter the condensed water storage tank 18 through the overflow port 3 through the overflow pipe 23, so , when the water level detected by the capacitive water level sensor (water level detection sensor 8) is _H≥H0 , the clothes dryer will stop working and give an alarm to remind the user that the water box 4 is full, and the user can remove the water box 4 from the water box accommodating chamber 2 Extract and pour off the water. Figure 1 shows the state where the water box 4 is half drawn out in the water box accommodation cavity 2. At this time, since the water level detection channel 7 has left the water box 4, the baffle plate 9 is closed, preventing the water in the water box from flowing out from the water level detection port 6 .

Fig. 3 is a schematic diagram when the water level detection channel is connected to the water box, and Fig. 4 is a schematic diagram when the water level detection channel is not connected to the water box. A sealing ring is arranged at the water level detection port 6, and when the water level detection channel 7 communicates with the water level detection port 6, water can be prevented from overflowing. The baffle 9 is supported by a spring. When the water level detection channel 7 communicates with the water level detection port 6, the baffle 9 is pushed open. When the water level detection channel 7 is not connected with the water level detection port 6, the baffle 9 is tightened under the action of the spring. Tightly closed on the rear wall of the water box 4.

Figure 7 is a schematic diagram of the working principle of the capacitive water level sensor. Water is a conductor, so the electrode of the capacitive water level sensor used is a strictly insulating electrode. The diameter of the water level detection channel 7 is D, the electrode diameter of the capacitive water level sensor is d, the dielectric constant of water is ε1, and the dielectric constant of air is is ε, the water level is H, and the electrode height is h, then the capacitance value of the capacitive sensor is:

Among them, C ₀ is the initial capacitance value determined by the basic size of the capacitive water level sensor, namely:

It can be seen from the formula that the capacitance increment of the capacitive water level sensor is proportional to the height H of the measured water level. Therefore, the water level in the water tank can be detected according to the capacitance value.

In summary, with the help of the above technical solution of the present invention, by setting a water level detection mechanism (a water level detection sensor and a water level detection channel) on the water box accommodation chamber 2, a water level detection mechanism that cooperates with the water level detection mechanism is set on the water box 4. 6, so that after the water box 4 is completely placed in the water box accommodation chamber 2, the water level detection mechanism will automatically penetrate into the water box 4 to directly detect the water level in the water box 4, so that the water level detection is more accurate and the alarm is more timely. , to prevent the overflow of condensate.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
