[0034] Embodiment 1
[0035] See also Figures 1 to 4 As shown, the dishwasher inner tank drying device provided in the present application includes a condensation air duct 101 and a cooling pipeline 127 .
[0036] The condensation air duct 101 includes an air duct 103 and a condenser 104, and a cooling end 107 of the condenser 104 is located in the air duct 103. The air duct 103 is provided with an air inlet 105 and an air outlet 106, both of which are connected to the inner tank of the dishwasher, and the air duct 103 is in a negative pressure state, so that the high-humidity hot steam in the inner tank is sucked into the air duct 103. When the hot steam passes through the cooling end 107 of the condenser 104, the moisture in the gas condenses into water droplets, and the remaining gas is discharged into the inner tank, thereby realizing the internal circulation of the gas between the inner tank and the air duct 103.
[0037] Since the heat absorbed by the condenser 104 is transferred from the cooling end 107 to the hot end 108, and the temperature difference between the two ends has a great influence on the heat transfer, the heat dissipation of the hot end 108 of the condenser 104 has a great influence on the working efficiency of the condenser 104. The present application integrates the respirator 102 and the condensation air duct 101 of the dishwasher, and uses the water flowing in the respirator 102 to dissipate the heat of the hot end 108 of the condenser 104. Since the specific heat capacity of water is large, water cooling, a commonly used heat dissipation method, can quickly dissipate the heat of the hot end 108 of the condenser 104.
[0038] Specifically, the respirator 102 is provided with a circulating water circuit 109, in which water for washing dishes flows. The respirator 102 is also provided with a cooling pipe 127, which is connected to the circulating water circuit 109 of the respirator 102, so that the circulating water circuit 109 can flow to the cooling pipe 127. The hot end 108 of the condenser 104 is located in the cooling pipe 127, and the water in the circulating water circuit 109 can be used to cool the hot end 108 of the condenser 104. The temperature drop of the hot end 108 of the condenser 104 creates better heat transfer conditions for the condenser 104, and the temperature of the cooling end 107 drops accordingly, which has a better condensation effect on hot steam.
[0039] The dishwasher inner tank drying device provided in the present application adopts a condenser 104 to dry the inner tank with moist hot steam, which is more efficient than the traditional PTC heating air drying method, and integrates the dishwasher's breather 102 and the condensation duct 101 into an integrated design, providing the condenser 104 with a better water cooling and heat dissipation effect, effectively improving the working efficiency of the condenser 104, saving manufacturing and installation processes, and improving production efficiency.
[0040] In the optional solution of this embodiment, Figure 3 As shown, the condenser 104 is a semiconductor condenser 104 formed by a plurality of semiconductor condensation sheets 110. When the semiconductor condenser 104 is powered on, under the action of an external electric field, electrons move in a directional manner to carry heat from one end (cooling end 107) to the other end (hot end 108), thereby achieving the effect of condensing the hot steam at the cooling end 107.
[0041] In an optional scheme of this embodiment, the condensing air duct 101 includes a fan 111, and the air duct 103 is provided with an installation cavity 112. The fan 111 is installed in the installation cavity 112 to form a negative pressure state in the air duct 103, so that the gas can circulate between the inner tank and the air duct 103 to reduce the air humidity in the inner tank.
[0042] Specific as Figure 2 As shown, the air inlet of the fan 111 is connected to the outside air, and the installation cavity 112 is provided with a nozzle section 113, which is connected to the air outlet of the fan 111 and the air duct 103; along the flow pattern of the airflow, the flow area of the nozzle section 113 gradually shrinks and then expands.
[0043] In this embodiment, since the air humidity in the inner tank is relatively high, if the fan 111 is directly used to extract the steam in the inner tank into the air duct 103 for circulation, it is easy to cause corrosion to the fan 111, affecting the life of the fan 111. The present application uses the fan 111 to send the outside air into the air duct 103, and the air flow area at the contraction part 114 of the nozzle section 113 is reduced to increase the air flow rate, thereby forming a high-speed low-pressure area in the cross section of the nozzle section 113, and the air begins to diffuse at the diffusion part 115 of the nozzle section 113, thereby driving the gas in the air duct 103 to flow, that is, forming a negative pressure state in the air duct 103, so that the hot and humid steam in the inner tank flows into the air duct 103, but the hot and humid steam does not pass through the fan 111, and will not cause corrosion to the fan 111.
[0044] In an optional solution of this embodiment, the fan 111 is configured to be started intermittently.
[0045] In this embodiment, if the fan 111 continues to send outside air into the air duct 103, the gas pressure in the inner tank will rise, thereby causing steam leakage from the door gap of the dishwasher. Therefore, the fan 111 adopts intermittent operation, that is, the fan 111 stops working until the gas pressure in the inner tank reaches the critical point of steam leakage pressure, and continues to work when the gas pressure in the inner tank returns to stability. During the period when the fan 111 stops working, the low-temperature water flowing in the cooling pipeline 127 continues to dissipate heat to the hot end 108 of the semiconductor condenser 104 until the next working stage of the fan 111 begins. In this way, the working efficiency of the semiconductor condenser 104 is higher.
[0046] In an optional solution of this embodiment, the air duct 103 is provided with a condensate outlet 116 , which is located at a low position of the air duct 103 and close to the air outlet 106 ; the condensate outlet 116 is connected to the cooling pipeline 127 .
[0047] In this embodiment, after the hot and humid steam of the inner tank flows into the air duct 103, the hot and humid steam contacts the cooling end 107 of the semiconductor condenser 104, and the water vapor in the gas condenses to form water droplets. Under the action of gravity, the condensed water droplets can gather at the condensed water outlet 116 at a lower position, and flow out of the air duct 103 from the condensed water outlet, and flow to the cooling pipeline 127, so that the condensed water can be collected through the cooling pipeline 127, and the condensed gas can return to the inner tank from the air outlet 106 of the air duct 103, that is, the air in the inner tank is dried.
[0048] Embodiment 2
[0049] The dishwasher inner tank drying device in the second embodiment is an improvement on the above embodiment, and the technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.
[0050] See also Figure 4 As shown, in an optional solution of this embodiment, the cooling pipeline 127 includes a main circuit 117, a refrigeration branch 118 and a drainage branch 119. The main circuit 117 is provided with a water cooling chamber 120 to install the hot end 108 of the condenser 104; one of the refrigeration branch 118 and the drainage branch 119 is connected to the main circuit 117, so that the cooling water circulates between the main circuit 117 and the refrigeration branch 118, or the cooling water at the end of the main circuit 117 is discharged from the drainage branch 119. Preferably, the refrigeration branch 118 is provided with a circulation pump 121; the drainage branch 119 is provided with a solenoid valve 122.
[0051] In this embodiment, after the dishwasher starts working, water enters the circulating water circuit 109 through the water inlet 123 of the breather 102, and flows from the circulating water circuit 109 into the cooling pipe 127. At this time, the solenoid valve 122 located in the drainage branch 119 is closed, and the water fills the cooling pipe 127 and then enters the water softener through the water inlet 124. In the inner tank drying stage, the circulation pump 121 located in the cooling branch 118 is started, and the water in the cooling pipe 127 begins to circulate to cool the hot end 108 of the semiconductor condenser 104 in the water cooling chamber 120.
[0052] Furthermore, the refrigeration branch 118 is provided with a heat exchange pipeline 125, which is formed by a zigzag heat-conducting pipe to increase the heat dissipation area. After being heated by the hot end 108 of the semiconductor condenser 104 in the water-cooling chamber 120, the water enters the heat exchange pipeline 125 through the circulation pump 121. Optionally, the heat exchange pipeline 125 is made of copper, which has good thermal conductivity. The water cools down in the heat exchange pipeline 125, and then continues to enter the water-cooling chamber 120 to cool down the hot end 108 of the semiconductor condenser 104. This process continues until the drying process is completed, the drainage solenoid valve 122 is opened, and the water can be discharged from the drainage port 126 of the drainage branch 119 into the water cup, and then discharged by the drainage pump.
