Description

Technical Field

[0001] This application relates to the field of drying technology, and more particularly to a drying apparatus and a dishwasher. Background Technology

[0002] With the continuous development of electrical appliance technology, the types of electrical appliances are becoming more and more diverse. Among them, cleaning equipment (such as dishwashers) can automatically clean kitchen utensils (such as bowls, chopsticks, pots and pans), effectively freeing up users' hands and bringing them a better cooking experience.

[0003] A dishwasher includes an inner tub to hold and clean the dishes. It also includes a drying unit with a condenser fin. After washing, the hot, humid air from the tub enters the drying unit, where it is condensed by the condenser fin to reduce humidity before being returned to the tub to dry it. However, over time, the condenser fin can heat up, affecting its effectiveness. To address this, a ventilation opening is typically located on one side of the condenser fin to dissipate heat and cool it down.

[0004] However, in the aforementioned drying device, the flow between the heat dissipation opening and the outside gas is poor, which reduces the cooling effect of the heat dissipation opening on the condenser plate. Utility Model Content

[0005] This application provides a drying device and a dishwasher, which can effectively improve the heat exchange efficiency between the heat exchanger and the outside gas, and enhance the cooling effect on the heat exchanger.

[0006] One aspect of this application provides a drying apparatus for use in a dishwasher, the dishwasher having an inner tub, comprising:

[0007] The base shell has a circulation channel and a first air inlet and a first air outlet communicating with the circulation channel. The first air inlet and the first air outlet are both used to communicate with the inner liner.

[0008] A circulating fan is installed in the circulation channel. The circulating fan is used to send the gas in the inner liner into the circulation channel through the first air inlet and send it back to the inner liner through the first air outlet.

[0009] A heat exchanger is used to exchange heat with the circulation channel and to condense the gas fed into the circulation channel to reduce the humidity of the gas.

[0010] A cooling fan is mounted on the base shell, which has a heat dissipation opening. The side of the heat exchanger facing away from the circulation channel is exposed through the heat dissipation opening and connected to the outside. The cooling fan is used to blow air toward the exposed part of the heat exchanger to dissipate heat and cool the heat exchanger.

[0011] This application provides a drying device that connects the exposed portion of a heat exchanger to the outside environment. When a cooling fan blows air onto this exposed portion, it creates a localized negative pressure, drawing in surrounding gas and facilitating heat exchange between the heat exchanger and the surrounding air. This effectively increases the gas flow velocity at the heat exchanger, thereby improving the heat exchange efficiency between the heat exchanger and the external air and enhancing the cooling effect on the heat exchanger.

[0012] In one possible implementation, the heat dissipation opening is formed in the recess of the base shell.

[0013] In one possible implementation, the base shell includes a connected lower base and an upper base cover, the lower base and the upper base cover together enclosing the circulation channel;

[0014] The heat dissipation opening is formed by the inward indentation of part of the bottom wall and part of the side wall of the lower base, and the inward indentation of part of the bottom wall forms a first concave surface, and the inward indentation of part of the side wall forms a second concave surface.

[0015] In one possible implementation, the bottom wall of the lower base is connected to the inner liner;

[0016] The inner liner closes the heat dissipation opening formed by the concave bottom wall of the portion thereof, and the inner liner is opposite to the first concave surface.

[0017] In one possible implementation, the bottom wall of the lower base includes a connected main body and a heat dissipation part;

[0018] The main body is fitted to the inner liner, and the heat dissipation part is recessed inward relative to the main body in the direction of the circulation channel to be spaced apart from the inner liner, so as to form the heat dissipation opening between the heat dissipation part and the inner liner.

[0019] In one possible implementation, the first air inlet is disposed in the main body, and the heat exchanger is disposed in the heat dissipation part;

[0020] The bottom wall of the lower base also includes a guide ramp, which connects the main body and the heat dissipation part. Gas entering the circulation channel from the first air inlet is guided by the guide ramp and then exchanges heat with the heat exchanger.

[0021] In one possible implementation, the base shell includes a connected lower base and an upper base cover, the lower base being connected to the inner liner, and the upper base cover being located on the side of the lower base facing away from the inner liner;

[0022] The air inlet of the cooling fan is located on the upper base cover.

[0023] In one possible implementation, the heat exchanger includes opposing first and second sides;

[0024] The first side is exposed to the outside through the heat dissipation opening, and the first side has a planar structure;

[0025] The second side is located within the circulation channel, and has a plurality of spaced-apart metal heat-conducting sheets.

[0026] In one possible implementation, the airflow direction of the circulation channel at the heat exchanger is a first direction, and the airflow direction of the heat dissipation opening at the heat exchanger is a second direction, with the angle between the first direction and the second direction being 135°~180°.

[0027] A second aspect of this application provides a dishwasher, including an inner tub and any of the drying devices described above. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0048] This application provides a drying device and a dishwasher. The dishwasher may include an inner tub for holding tableware to be cleaned, allowing the dishwasher to clean the tableware inside. After cleaning, the tableware needs to be dried to reduce moisture, thereby reducing or preventing excessive moisture from causing bacterial growth and improving the health of the tableware.

[0049] As described in the background section, dishwashers typically include a drying unit with a condenser plate. After the dishes are washed, the hot, humid air from the inner drum enters the drying unit, where it is condensed by the condenser plate to reduce its humidity before being returned to the inner drum for drying. However, over time, the temperature of the condenser plate can rise, affecting its condensation efficiency. Therefore, a heat dissipation vent is usually provided on one side of the condenser plate to dissipate heat and lower its temperature.

[0050] However, in the aforementioned drying device, the flow between the heat dissipation opening and the outside gas is poor, which reduces the cooling effect of the heat dissipation opening on the condenser plate.

[0051] To address the aforementioned problems, this application provides a drying device that connects a portion of the exposed area of ​​a heat exchanger to the outside environment. This allows a cooling fan to create a negative pressure at the exposed area of ​​the heat exchanger while blowing air onto it. This draws in surrounding gas, enabling heat exchange between the heat exchanger and the surrounding air. This effectively increases the gas flow velocity at the heat exchanger, thereby improving the heat exchange efficiency between the heat exchanger and the outside air, and enhancing the cooling effect on the heat exchanger.

[0052] The drying apparatus provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0053] Figure 1 This is a schematic diagram of the structure of a drying device and its inner liner provided in an embodiment of this application. Figure 2 This is a schematic diagram of the internal structure of a drying device provided in an embodiment of this application. Figure 3 This is a schematic diagram of the structure of a drying device provided in an embodiment of this application from one perspective. Figure 4 This is an exploded view of a drying apparatus provided in an embodiment of this application.

[0054] This application provides a drying apparatus 100, see [link to previous document]. Figure 1 and Figure 2 As shown, the drying device 100 can be used in a dishwasher, and the drying device 100 can be disposed on the side of the inner tank 200. The drying device 100 may include a base shell 110, a circulating fan 120, and a heat exchanger 130. The base shell 110 may have a circulation channel 111 and a first air inlet 112 and a first air outlet 113 communicating with the circulation channel 111. The first air inlet 112 and the first air outlet 113 may both be used to communicate with the inner tank 200.

[0055] A circulating fan 120 can be installed inside the circulation channel 111. The circulating fan 120 can be used to send the gas from the inner liner 200 into the circulation channel 111 through the first air inlet 112 and back into the inner liner 200 through the first air outlet 113. For example, the circulating fan 120 can generate negative pressure in the circulation channel 111, so that the gas from the inner liner 200 is sent into the circulation channel 111 through the first air inlet 112 and back into the inner liner 200 through the first air outlet 113.

[0056] The heat exchanger 130 can be used to exchange heat with the circulation channel 111 and condense the gas fed into the circulation channel 111 to reduce the humidity of the gas. For example, the heat exchanger 130 can be a condenser plate, and the heat exchanger 130 can have multiple spaced metal heat-conducting plates, with gaps between adjacent metal heat-conducting plates. Gas can flow through the gaps through the heat exchanger 130, and during the process of the gas passing through the gaps, it can exchange heat with the heat exchangers 130 on both sides of the gaps. The temperature of the metal heat-conducting plates is relatively low. When encountering humid and hot gas, the moisture and heat in the gas can be transferred to the metal heat-conducting plates, allowing the metal heat-conducting plates to condense the humid and hot gas.

[0057] For example, after cleaning, the inner liner 200 is filled with hot, humid gas. This gas enters the circulation channel 111 and comes into contact with the heat exchanger 130, whose temperature is relatively lower than that of the inner liner 200. The low-temperature environment of the heat exchanger 130 cools the gas as it enters the circulation channel 111. When the gas temperature drops to the dew point temperature, condensate begins to form, reducing the moisture content of the gas. Thus, the hot, humid gas is condensed into low-temperature dry gas and condensate.

[0058] Specifically, after the dishwasher finishes washing the dishes, the inner tank 200 is filled with hot and humid air. At this time, the circulating fan 120 can be turned on to draw the hot and humid air from the inner tank 200 into the circulation channel 111. In the circulation channel 111, the hot and humid air encounters the heat exchanger 130 and condenses, turning it into low-temperature dry air and condensate. The condensate flows into the inner tank 200 and eventually exits. The low-temperature dry air is then returned to the inner tank 200 by the circulating fan 120. This cycle continues until all the hot and humid air in the inner tank 200 is converted into low-temperature dry air, effectively drying the dishes in the inner tank 200.

[0059] See Figure 2 and Figure 3 As shown, the dishwasher may also include a cooling fan 150, which can be mounted on the base housing 110, in conjunction with... Figure 4As shown, the base shell 110 may have a heat dissipation opening 101. The side of the heat exchanger 130 facing away from the circulation channel 111 can be exposed through the heat dissipation opening 101 and connected to the outside. The cooling fan 150 can be used to blow air toward the exposed part of the heat exchanger 130 to dissipate heat and cool the heat exchanger 130.

[0060] When the cooling fan 150 blows air onto the exposed parts of the heat exchanger 130, it creates a localized negative pressure at those exposed areas, drawing in surrounding air and exchanging heat with it. This effectively increases the airflow velocity at the heat exchanger 130, thereby improving the heat exchange efficiency between the heat exchanger 130 and the external air, and enhancing the cooling effect on the heat exchanger 130.

[0061] Compared to the heat dissipation opening structure in related technologies, the drying device 100 provided in this application embodiment connects a portion of the exposed side of the heat exchanger 130 to the outside. This allows the cooling fan 150 to create a negative pressure in the exposed part of the heat exchanger 130 during airflow, drawing in surrounding gas and facilitating heat exchange between the heat exchanger 130 and the surrounding gas. This effectively increases the gas flow velocity at the heat exchanger 130, thereby improving the heat exchange efficiency between the heat exchanger 130 and the outside gas, and enhancing the cooling effect on the heat exchanger 130.

[0062] See Figure 3 As shown, the base shell 110 can be recessed to form a heat dissipation opening 101. The recessed portion can create a larger space in the corresponding part of the base shell 110, which can increase the space of the heat dissipation opening 101, allowing the heat exchanger 130 to fully contact the outside air at the heat dissipation opening 101, thereby achieving heat dissipation and cooling of the heat exchanger 130, effectively improving the cooling effect of the heat exchanger 130, and thus improving the condensation effect of the heat exchanger 130.

[0063] See also Figure 4 As shown, the base shell 110 may include a connected lower base 114 and an upper base cover 115, which can together form a circulation channel 111. For example, the lower base 114 and the upper base cover 115 can be connected by means of adhesive, fastening, bolting or snap-fit.

[0064] See Figure 3The lower base 114 may have a portion of its bottom wall and a portion of its side wall recessed to form a heat dissipation opening 101. The recessed bottom wall may form a first concave surface 1011, and the recessed side wall may form a second concave surface 1012. For example, a portion of the bottom wall of the lower base 114 may be offset toward the upper base cover 115 to form the first concave surface 1011. A portion of the side wall of the lower base 114 may be offset toward its opposite side wall to form the second concave surface 1012.

[0065] By making part of the bottom wall and part of the side wall of the lower base 114 concave, a heat dissipation opening 101 can be formed on the base shell 110. This allows the heat dissipation opening 101 to have a larger space, enabling it to contact the outside through the side and bottom wall directions. This effectively improves the heat exchange efficiency between the heat dissipation opening 101 and the outside gas, thereby effectively enhancing the cooling effect on the heat exchanger 130.

[0066] In this embodiment, the bottom wall of the lower base 114 can be connected to the inner liner 200. The inner liner 200 can partially close the heat dissipation opening 101 formed by the concave bottom wall, and the inner liner 200 can be opposite to the first concave surface 1011. That is, the inner liner 200 is closed off from the first concave surface 1011, so that the inner liner 200 and the first concave surface 1011 are spaced apart, thereby forming a heat dissipation opening 101 between the inner liner 200 and the base shell 110.

[0067] This allows the heat exchanger 130 to connect with the outside at the heat dissipation opening 101, enabling outside air to enter the heat dissipation opening 101 and exchange heat with the heat exchanger 130 to dissipate heat and cool down the heat exchanger 130. This allows the heat exchanger 130 to maintain a lower temperature, thus providing a better condensation effect for the gas in the circulation channel 111.

[0068] See Figure 3 As shown, the bottom wall of the lower base 114 may include a connected main body 1141 and a heat dissipation part 1142. The main body 1141 can fit against the inner liner, and the heat dissipation part 1142 can be recessed relative to the main body 1141 in the direction of the circulation channel 111 to be spaced apart from the inner liner 200, so that a heat dissipation opening 101 can be formed between the heat dissipation part 1142 and the inner liner 200. That is, the heat dissipation part 1142 is recessed relative to the main body 1141 in a direction away from the inner liner 200, and the heat dissipation part 1142 and the main body 1141 are not on the same plane. When the lower base 114 is connected to the inner liner 200, the main body 1141 can contact and connect with the inner liner 200, while the heat dissipation part 1142 is offset in a direction away from the inner liner 200, so that the heat dissipation part 1142 has a gap space between the inner liner 200 to form the heat dissipation opening 101.

[0069] This allows the heat exchanger 130 to connect with the outside through the heat dissipation opening 101. Under the action of the cooling fan 150, outside air can be drawn into the heat dissipation opening 101. This allows the heat exchanger 130 to fully contact the outside air and exchange heat, thereby dissipating heat and cooling the heat exchanger 130, effectively improving its heat dissipation effect.

[0070] See also Figure 3 As shown, the first air inlet 112 can be disposed on the main body 1141, and the heat exchanger 130 can be disposed on the heat dissipation part 1142. The bottom wall of the lower base 114 may also include a guide ramp 116, which can connect the main body 1141 and the heat dissipation part 1142. The gas entering the circulation channel 111 from the first air inlet 112 can be guided by the guide ramp 116 and exchange heat with the heat exchanger 130.

[0071] The guide ramp 116 guides the airflow, allowing it to smoothly reach the heat exchanger 130 after entering the circulation channel 111 from the first air inlet 112, thus exchanging heat and achieving cooling and condensation. This prevents airflow from accumulating at the corner between the main body 1141 and the heat dissipation section 1142, which would otherwise affect normal airflow. It effectively improves the smoothness of airflow, increasing the circulation speed and efficiency of the gas in the circulation channel 111 and the inner tank 200, thereby significantly improving the drying efficiency of the inner tank 200.

[0072] See also Figure 3 As shown, the heat dissipation part 1142 can be located at the edge of the lower base 114, so that at least a portion of the periphery of the heat dissipation opening 101 is in communication with the outside. That is, only the side of the heat dissipation part 1142 closest to the main body 1141 is not in communication with the outside, while the rest of the periphery is unobstructed, allowing the heat dissipation opening 101 to be fully in communication with the outside. It can be understood that the heat dissipation opening 101 is basically an open structure, so that under the action of the circulating fan 120, the outside air can quickly enter the heat dissipation opening 101 through the periphery. This can effectively accelerate the air flow rate at the heat dissipation opening 101, improve the heat exchange efficiency of the heat exchanger 130, and thus effectively improve the heat dissipation effect of the heat exchanger 130.

[0073] Moreover, the heat dissipation opening 101 is basically in an open state, and its internal structure is relatively smooth. There are no ribs or other structures that obstruct the flow of gas, which can effectively reduce the noise of gas flow and has a good noise reduction effect.

[0074] In this embodiment, the air inlet of the cooling fan 150 can be located on the upper base cover 115. This avoids the air inlet of the cooling fan 150 being opposite the inner liner 200, preventing the inner liner 200 from obstructing the air inlet. This effectively increases the airflow at the air inlet of the cooling fan 150, thereby effectively improving the circulation efficiency of the air at the heat dissipation opening 101 and enhancing the cooling effect on the heat exchanger 130.

[0075] The heat exchanger 130 may include a first side and a second side opposite to each other. The first side may be exposed to the outside through a heat dissipation opening 101 and may be a planar structure. The second side may be located within the circulation channel 111 and may have a plurality of spaced-apart metal heat-conducting fins.

[0076] The spaced-apart metal heat-conducting fins have gaps between them. When the gas in the circulation channel 111 passes through the heat exchanger 130, it can enter into the gaps between the metal heat-conducting fins, allowing for sufficient contact with the fins and thus cooling and dehumidifying the gas. The spaced-apart metal heat-conducting fins effectively increase the contact area between the heat exchanger 130 and the gas, thereby improving the heat exchange efficiency of the heat exchanger 130 and its dehumidification effect.

[0077] See Figure 2 As shown, the airflow direction of the circulation channel 111 at the heat exchanger 130 is the first direction (i.e., Figure 2 (x direction in the image), the airflow direction of the heat dissipation opening 101 at the heat exchanger 130 is the second direction (i.e., the x direction in the image), Figure 2 The angle between the first and second directions is 135°~180° (in the y-direction). This reduces the size of the heat dissipation channel 114 in the width direction of the drying device 100, which helps to reduce the overall structural size of the drying device 100, thereby effectively reducing the space occupied by the drying device 100 in the dishwasher and improving the internal space layout of the dishwasher.

[0078] Figure 5 This is a schematic diagram of the structure of a drying device provided in an embodiment of this application from another perspective.

[0079] See Figure 4 and Figure 5 As shown, the upper base cover 115 may have a first mounting port 1151, which can communicate with the circulation channel 111 and be opposite to the heat exchanger 130. The heat exchanger 130 can be installed in the circulation channel 111 through the first mounting port 1151. The base shell 110 may also include a first mounting cover 1152, which can be placed on the first mounting port 1151 and detachably connected to the upper base cover 115.

[0080] For example, during the assembly of the drying device 100, the lower base 114 can be connected to the upper base cover 115 first, and then the heat exchanger 130 can be installed into the circulation channel 111 through the first mounting port 1151. After the installation of the heat exchanger 130 is completed, the first mounting cover 1152 can be installed on the first mounting port 1151 to close the first mounting port 1151.

[0081] The first mounting cover 1152 can seal the first mounting port 1151, thereby improving the sealing performance of the circulation channel 111. By opening the first mounting port 1151 on the upper base cover 115 and setting the first mounting cover 1152 on the first mounting port 1151, the installation of the heat exchanger 130 can be facilitated. Furthermore, it can simplify the overall structure of the upper base cover 115, facilitate the production of the upper base cover 115, help reduce the production difficulty of the upper base cover 115, and improve the production efficiency of the upper base cover 115.

[0082] See also Figure 2 As shown, the drying device 100 may further include a heating module 140, which can be installed in the circulation channel 111 and can be used to heat the gas fed into the circulation channel 111. Along the extension direction of the circulation channel 111, the circulating fan 120 can be located between the heat exchanger 130 and the heating module 140, and the heat exchanger 130 can be located near the first air inlet 112, and the heating module 140 can be located near the first air outlet 113.

[0083] For example, after the humid and hot air in the inner liner 200 enters the circulation channel 111, under the action of the heat exchanger 130, the temperature of the humid and hot air drops, and it becomes low-temperature dry air before returning to the inner liner 200. After multiple cycles, the air temperature in the inner liner 200 decreases. The evaporation rate of residual water on the tableware gradually decreases, and the humidity in the air decreases.

[0084] At this point, the heating module 140 can be activated. The heating module 140 heats the air in the circulation channel 111 to deliver high-temperature air into the inner tank 200. This raises the temperature inside the inner tank 200, allowing residual water on the dishes to evaporate under the high temperature, thus reducing the amount of residual water and accelerating the overall drying speed of the dishes, thereby effectively improving the overall drying efficiency of the dishwasher.

[0085] By positioning the circulating fan 120 between the heat exchanger 130 and the heating module 140, the air in the inner liner 200, after entering the circulation channel 111, can first pass through the heat exchanger 130, then through the heating module 140, and finally enter the inner liner 200 through the first air outlet 113.

[0086] In this way, the air in the inner liner 200 is dehumidified before passing through the heat exchanger 130, thus reducing the humidity. The air condensed by the heat exchanger 130 becomes low-temperature dry air. This low-temperature dry air then reaches the heating module 140 and is heated, becoming high-temperature dry air. This allows high-temperature dry air to be supplied to the inner liner 200, reducing humidity and increasing temperature, enabling residual water on the tableware to evaporate quickly in a high-temperature, dry environment, thereby accelerating the drying process and improving drying efficiency.

[0087] See Figure 4 and Figure 5 As shown, the upper base cover 115 may also have a second mounting port 1153, which can communicate with the circulation channel 111 and is opposite to the heating module 140. The heating module 140 is installed in the circulation channel 111 through the second mounting port 1153. The base shell 110 also includes a second mounting cover 1154, which covers the second mounting port 1153 and is detachably connected to the upper base cover 115.

[0088] For example, during the assembly of the drying device 100, after connecting the lower base 114 to the upper base cover 115, the heating module 140 can be first installed into the circulation channel 111 through the second mounting port 1153. After the installation of the heating module 140 is completed, the second mounting cover 1154 is then installed on the second mounting port 1153 to close the second mounting port 1153.

[0089] The second mounting cover 1154 can seal the second mounting port 1153, thereby improving the sealing performance of the circulation channel 111. By opening the second mounting port 1153 on the upper base cover 115 and setting the second mounting cover 1154 on the second mounting port 1153, the installation of the heating module 140 can be facilitated. Furthermore, it can simplify the overall structure of the upper base cover 115, facilitate the production of the upper base cover 115, help reduce the production difficulty of the upper base cover 115, and improve the production efficiency of the upper base cover 115.

[0090] See Figure 2 As shown, it also includes a temperature and humidity detector 160, which is located in the circulation channel 111 and near the first air outlet 113. The temperature and humidity detector 160 is used to detect the temperature and humidity of the gas entering the inner liner 200.

[0091] For example, the temperature and humidity detector 160 can be a temperature and humidity sensor that can detect the humidity and temperature of the air at the first air outlet 113 in real time, so as to confirm the temperature and humidity of the air entering the inner tank 200. Thus, the system can determine when to turn on the heating module 140 based on the temperature and humidity of the air in the inner tank 200.

[0092] For example, when the temperature in the inner pot 200 drops to the preset temperature value, it means that the evaporation rate of residual water on the tableware decreases. At this time, the heating module 140 can be turned on so that the heating module 140 can heat the air supplied to the inner pot 200, thereby increasing the temperature of the inner pot 200 and allowing the residual water on the tableware to evaporate quickly, thus improving the evaporation efficiency of the tableware.
