Description

It's particularly useful during winter in northern China and during the return of the south wind in southern China, when clothes are difficult to dry. Dryers are also widely used in industrial production to dry fabrics and improve production efficiency.

[0003] However, the existing electric heating type dryers have high electric heating energy consumption and high cost. Therefore, many heat pump type dryers are now used.

[0004] The heat exchange module of an existing heat pump dryer generally includes a compressor, an evaporator, a condenser, a throttle valve, and other structures, all of which are fixed to the bottom plate of the housing. A water receiving tank needs to be installed below the evaporator to receive the condensed water droplets. However, due to limited space, the volume of the water receiving tank is relatively small. When the humidity of the clothes is relatively high during use, the water receiving tank will quickly fill up and need to be drained immediately, which greatly increases the frequency of starting and stopping the water pump installed on it, shortening its service life.

[0050] The evaporator 20, condenser 30, compressor assembly 40, first electronic expansion valve 60 and second electronic expansion valve 70 in this embodiment all adopt conventional structures and will not be described in detail here. The auxiliary heat exchanger 50 also adopts a conventional heat exchanger and will not be described in detail here.

[0051] When this embodiment is in use, it is installed on the dryer body (the dryer body is omitted and not shown in the drawings), a first temperature sensor 1 is installed on the right side of the auxiliary heat exchanger 50 at the air inlet channel of the right part of the main body, a second temperature sensor 2 is fixed to the outer wall of the connecting pipe connected to the outlet of the evaporator 20, a third temperature sensor 3 is fixed to the outer wall of the connecting pipe connected to the outlet of the auxiliary heat exchanger 50, a fourth temperature sensor 4 is fixed to the outer wall of the connecting pipe connected to the air outlet of the compressor assembly 40, a fifth temperature sensor 5 is fixed to the outer wall of the connecting pipe connected to the outlet of the condenser 30, a sixth temperature sensor 6 is fixed to the bottom surface of the upper cover plate 18 at the main air outlet 16 or to the dryer body on the right side of the main air outlet 16, and a seventh temperature sensor 7 and a humidity sensor 8 are fixed to the bottom surface of the upper extension plate 14;

[0052] All electrical components are electrically connected to the control host through electrical connecting lines, and the operation is controlled by the control host. The control host is installed on the shell of the dryer body. This is a conventional structure and will not be described in detail here.

[0053] The top surface of the upper extension plate 14 is formed with an upper air inlet groove 141 extending forward and backward. The upper air inlet groove 141 and the main air inlet 15 are connected to the air outlet of the drying cylinder of the dryer body, and the main air outlet 16 is connected to the air inlet of the drying cylinder.

[0054] The working principle of this embodiment is as follows:

[0055] When the machine is started up, the main ventilation fan 80 is turned on. When the weather is hot, such as above 30°C, the auxiliary ventilation fan 51 is turned on at the same time. At this time, the first electronic expansion valve 60 is opened to 250 steps (the electronic expansion valve control mode is that all are opened for 500 steps when powered on, and then reduced from 500 steps to 250 steps), and the second electronic expansion valve 70 is opened to 150 steps (the electronic expansion valve control mode is that all are opened for 500 steps when powered on, and then reduced from 500 steps to 150 steps). After 5 seconds, the compressor assembly 40 starts, and the temperature of each point is determined after running for 1 minute.

[0056] When the temperature detected by the first temperature sensor 1 is ≥ the temperature detected by the third temperature sensor 3, when the exhaust temperature of the compressor assembly 40, that is, the temperature detected by the fourth temperature sensor 4, is <105°C (in this embodiment, the temperature of the compressor assembly 40 is controlled below 105°C to prevent shutdown due to excessive temperature), the opening of the first electronic expansion valve 60 is closed, and is reduced by 20 steps each time. The judgment is made every 3 minutes, and then the opening of the first electronic expansion valve 60 is reduced once, that is, the opening of the first electronic expansion valve 60 is reduced by 20 steps every 3 minutes. During this process, the second electronic expansion valve 70 is not adjusted, and during this process, the opening of the first electronic expansion valve 60 cannot be less than the opening of the second electronic expansion valve 70. If the opening of the first electronic expansion valve 60 = the opening of the second electronic expansion valve 70, the opening of the second electronic expansion valve 70 is synchronously reduced to ensure that the opening of the second electronic expansion valve 70 is always less than the opening of the first electronic expansion valve 60.

[0057] At this time, the auxiliary heat exchanger 50 is used as an evaporator, and it cooperates with the evaporator 20 to achieve two-level regulation, that is, the refrigerant enters the auxiliary heat exchanger 50 from the condenser 30 through the throttling of the first electronic expansion valve 60, realizing the first evaporation and cooling. At the same time, the air passing through the auxiliary heat exchanger 50 is quickly cooled and blown onto the compressor assembly 40, which can cool the compressor assembly 40 (because the temperature detected by the first temperature sensor 1 is ≥ the temperature detected by the third temperature sensor 3, indicating that the external temperature is high, the compressor assembly 40 can be quickly raised after being blown in, so that the temperature of the compressor assembly 40 is too high to prevent the temperature from exceeding 105°C. It is necessary to cool down or keep warm to prevent excessive temperature rise). Then, it is throttled for the second time through the second electronic expansion valve 70, and then enters the evaporator 2 0 performs a second evaporation cooling, thereby causing the refrigerant in the evaporator 20 to absorb a large amount of heat, greatly reducing the temperature of the air entering from the upper air inlet groove 141 and the main air inlet 15, causing a large amount of water vapor in the wind to condense into water droplets and fall into the lower liquid guide groove 91 and enter the water flow chamber 100, thereby realizing water collection. A water flow chamber 100 is formed between the bottom surface of the lower supporting partition member 90 and the bottom surface of the main heat exchange chamber. The water flow chamber 100 has a large volume and a large water storage capacity, so that the water will not immediately exceed the limit height, so that the water pump installed on the top surface of the first mounting base 113 does not need to be frequently turned on and is not easily damaged, thereby ensuring its operating effect. When the liquid level sensor senses that the water level is higher than the maximum limit, the water pump is controlled by the control host to pump water. The water outlet end of the water pump is connected to a water pipe and extends out of the dryer body to realize drainage.

[0058] The auxiliary heat exchanger 50 is used as an evaporator together with the evaporator 20 to greatly accelerate the condensation effect, so that the water vapor in the air passing through the evaporator 20 quickly condenses into water droplets, and the openings of the first electronic expansion valve 60 and the second electronic expansion valve 70 are small, and the pressure increases, so that the compressor assembly 40 has high compression (at this time, the power of the compressor assembly 40 gradually increases, and the energy consumption increases), and the temperature of the refrigerant coming out is high, which also increases the temperature of the condenser 30, so that the temperature of the air passing through the evaporator 20 rises rapidly after passing through the condenser 30, and the temperature is high when it comes out from the main air outlet 16 and enters the drying cylinder, which can quickly dry the clothes inside, greatly improving the drying effect and efficiency, shortening the drying time, and reducing energy.

[0059] During operation, when the temperature detected by the fourth temperature sensor 4 is ≥105°C, the opening of the first electronic expansion valve 60 is increased by 30 steps. This is determined every 3 minutes, and the opening of the first electronic expansion valve 60 is then increased once. That is, the opening of the first electronic expansion valve 60 is determined to be increased once every 3 minutes. During the increase process, if the temperature detected by the fourth temperature sensor 4 is greater than 110°C, any other logic is ignored and the opening of the first electronic expansion valve 60 is quickly adjusted to 500 steps. After 5 minutes of operation, if the temperature detected by the fourth temperature sensor 4 is still greater than 110°C, the opening of the second electronic expansion valve 70 is increased by 30 steps to 200 steps. After 2 minutes, it is determined again that the temperature detected by the fourth exhaust temperature sensor 4 is greater than 110°C, and the opening of the second electronic expansion valve 70 is increased by 30 steps. This is adjusted every 2 minutes until the temperature detected by the fourth temperature sensor 4 is less than 105°C. This setting is to prevent the compressor assembly 40 from being shut down and damaged due to excessive temperature (at this time, the operating power of the compressor assembly 40 is gradually reduced, and the energy consumption is gradually reduced).

[0060] When the temperature detected by the first temperature sensor 1 is less than the temperature detected by the third temperature sensor 3 (i.e., the external temperature is lower than the internal temperature), and at the same time, the temperature detected by the fourth temperature sensor 4 is less than 105°C, the opening of the second electronic expansion valve 70 is reduced (the opening of the first electronic expansion valve 60 remains unchanged. At this time, the auxiliary heat exchanger 50 is used as a condenser, which can increase the temperature of the air passing through the auxiliary heat exchanger 50 so that the air blown onto the compressor assembly 40 can heat up or keep the compressor assembly 40 warm to prevent it from being cooled by the cold wind from the outside, thereby accelerating the compressor assembly 40 to quickly enter the compression state and improve the compression effect). The opening is reduced by 15 steps each time, and the judgment is made every 3 minutes. After that, the opening of the second electronic expansion valve 70 is reduced once, that is, the opening of the second electronic expansion valve 70 is determined to be reduced by 15 steps every 3 minutes. During this process, the first electronic expansion valve 60 remains unchanged. When the second electronic expansion valve 70 reaches 100 steps and the second electronic expansion valve 70 no longer decreases, the opening of the first electronic expansion valve 60 needs to be decreased, that is, the opening of P1 needs to be decreased by 30 steps, and the adjustment is performed every 3 minutes.

[0061] When the temperature detected by the fourth temperature sensor 4 is ≥105°C, the opening of the second electronic expansion valve 70 is increased by 30 steps, and the judgment is made every 3 minutes. Thereafter, the opening of the second electronic expansion valve 70 is increased once, that is, the opening of the second electronic expansion valve 70 is increased once every 3 minutes. During the increase process, if the temperature detected by the fourth temperature sensor 4 is greater than 110°C, any other logic is ignored and the opening of the first electronic expansion valve 60 is quickly adjusted to 500 steps. After running for 5 minutes, if the exhaust temperature is still greater than 110°C, the opening of the second electronic expansion valve 70 is increased by 30 steps. After 2 minutes, it is judged again that the temperature detected by the fourth temperature sensor 4 is greater than 110°C, and the opening of the second electronic expansion valve 70 is increased by 30 steps. The adjustment is made every 2 minutes until the temperature detected by the fourth temperature sensor 4 is less than 105°C.

[0062] The temperature of the sixth temperature sensor 6 is related to the air outlet temperature. The detected temperature continues to increase, indicating that the temperature of the condenser 30 is high, which indirectly reflects that the temperature of the compressor assembly 40 is high. It is necessary to observe whether the detected temperature of the fourth temperature sensor 4 is <105°C.

[0063] The humidity sensor 8 senses the humidity. When the humidity is greater than 70%, while ensuring that the detection temperature of the fourth temperature sensor 4 is less than 105°C, it is necessary to gradually reduce the opening of the first electronic expansion valve 60 and the opening of the second electronic expansion valve 70 so that the water vapor in the air blowing through the evaporator 20 quickly condenses into water droplets, thereby quickly dehumidifying.

[0064] When this embodiment is in use, the exhaust temperature of the compressor assembly 40, that is, the detection temperature of the fourth temperature sensor 4, is generally less than 105°C when it is just turned on. At this time, the power of the compressor assembly 40 continues to increase and is in a rapid drying state. Then, as the clothes are dried, the temperature detected by the sixth temperature sensor 6 continues to increase, and the temperature at the compressor assembly 40 also continues to increase. When the detection temperature of the fourth temperature sensor 4 is ≥105°C, it is necessary to increase the opening of the first electronic expansion valve 60 and the opening of the second electronic expansion valve 70. In this process, the energy consumption of the compressor assembly 40 is reduced, and energy saving is achieved while ensuring drying, with good energy saving effect.

[0065] In this embodiment, the opening of the first electronic expansion valve 60 and the second electronic expansion valve 70 is adjusted by the temperature sensed by the corresponding temperature sensor, thereby realizing the operation of the compressor assembly 40, changing its energy consumption, realizing dynamic adjustment, ensuring that energy consumption is reduced while drying clothes, and achieving energy-saving effects.

[0066] In this embodiment, the connecting pipe connecting the connector connected to the air outlet of the compressor assembly 40 and the connecting pipe connected to the air inlet of the condenser 30 is a hard copper pipe, and the connecting pipe connecting the connector connected to the outlet of the evaporator 20 and the connecting pipe connected to the inlet of the compressor assembly 40 is a hard copper pipe.

[0067] like Figure 10 As shown, the connector connected to the air outlet of the compressor assembly 40 and the connector connected to the air inlet of the condenser 30 are connected through a soft rubber tube 9, that is, one end of the soft rubber tube 9 is connected to the connector connected to the air outlet of the compressor assembly 40, and the other end is connected to the connector connected to the air inlet of the condenser 30; the connector connected to the outlet of the evaporator 20 and the connector connected to the inlet of the compressor assembly 40 are also connected through a soft rubber tube 9, that is, one end of this soft rubber tube 9 is connected to the connector connected to the inlet of the compressor assembly 40, and the other end is connected to the connector connected to the outlet of the evaporator 20.
