Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a channel structure and dishwasher with odor removal and drying functions. Background Technology

[0002] Current dishwasher drying units incorporate drying and ventilation systems. The combined use of these systems allows for timely exchange of air between the dishwasher cavity and fresh outside air, reducing odor buildup. However, in existing drying units, the drying and ventilation systems are too close together in height. This means that the hot air exhausted from the drying system may not fully reach all parts of the dishwasher cavity before being expelled by the ventilation mechanism, resulting in low drying efficiency and incomplete drying in corners of the cavity. Furthermore, the ventilation system in current drying units uses a two-position four-way valve to achieve both drying and ventilation functions, making its airflow path complex. Utility Model Content

[0003] The purpose of this invention is to provide a channel structure with odor removal and drying functions, which has the advantages of high drying efficiency, good odor removal effect, and simpler air path. Additionally, a dishwasher using the above-mentioned channel structure is also provided.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] In the first aspect, this utility model provides a channel structure with odor removal and drying functions, including an inner liner, a ventilation mechanism and a drying mechanism.

[0006] The drying mechanism is located on the bottom surface of the inner liner, and the ventilation mechanism is located on the top surface of the inner liner.

[0007] The ventilation mechanism has an air inlet and an air outlet. The air inlet forms a deodorization channel between the inner cavity of the inner liner and the drying mechanism, and the air outlet forms a drying channel between the inner cavity of the inner liner and the drying mechanism.

[0008] Furthermore, the channel structure also includes a filter assembly, which is connected to the air intake end of the air intake hole.

[0009] Furthermore, the filter assembly includes a housing and multiple filter layers;

[0010] The box body and the inner liner are detachably connected;

[0011] The multiple filter layers are located inside the housing and are distributed sequentially along the gas flow direction inside the housing;

[0012] The air inlet end of the air inlet is connected to the space inside the box.

[0013] Furthermore, the air inlet is provided with a first valve for controlling the opening and closing of the air inlet, and the air outlet is provided with a second valve for controlling the opening and closing of the air outlet.

[0014] Furthermore, the ventilation mechanism also includes a fan, which is connected to the air inlet to blow air into the inner liner through the air inlet.

[0015] Furthermore, the ventilation mechanism also includes a driver and a transmission assembly connected to the driver. The transmission assembly cooperates with the air inlet and the air outlet. The driver is used to drive the transmission assembly to selectively open or close the air inlet and the air outlet.

[0016] Furthermore, the transmission assembly includes a driving element and a driven disk;

[0017] The active component is connected to the driver;

[0018] The end face of the driven plate is attached to the air inlet and the air outlet. The driven plate is connected to the driving member and rotates relative to the air inlet and the air outlet under the drive of the driving member, so as to selectively open or close the air inlet and the air outlet.

[0019] Furthermore, the drying mechanism includes a vent pipe, a second fan, and a heating component. The second fan is connected to the vent pipe and is used to discharge outside air into the inner liner through the vent pipe. The heating component is connected to the vent pipe and is used to heat the gas discharged into the inner liner through the vent pipe.

[0020] Furthermore, a temperature sensor and / or a gas sensor are provided inside the inner liner. The temperature sensor is connected to the ventilation mechanism via a controller, and the gas sensor is connected to the ventilation mechanism via a controller.

[0021] Secondly, this utility model also provides a dishwasher, including the channel structure with ventilation function described in the above solution.

[0022] The channel structure and dishwasher with odor removal and drying functions provided by this utility model can produce the following beneficial effects:

[0023] Compared to existing technologies, the drying mechanism and ventilation mechanism in the channel structure provided by the first aspect of this utility model are far apart in height, which allows the drying air to fully spread to all parts of the inner liner before being discharged from the air outlet. This results in high drying efficiency and reduces the likelihood of incomplete drying in the corners of the cavity. Similarly, the ventilation air can also fully spread to all parts of the inner liner before being discharged from the drying mechanism, resulting in good odor removal. Furthermore, the ventilation system can achieve both drying and deodorization functions through the air inlet and outlet, eliminating the need for valve structures and simplifying the air path.

[0024] The dishwasher provided in the second aspect of this utility model has the channel structure with odor removal and drying functions provided in the first aspect of this utility model, and thus has all the beneficial effects of the channel structure provided in the first aspect of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0035] The first aspect of this utility model provides a channel structure with odor removal and drying functions, such as... Figures 1 to 3 As shown, it includes:

[0036] Inner liner 1, ventilation mechanism 2, and drying mechanism 3;

[0037] The drying mechanism 3 is located on the bottom surface of the inner liner 1, and the ventilation mechanism 2 is located on the top surface of the inner liner;

[0038] The ventilation mechanism 2 has an air inlet 22 and an air outlet 23. The air inlet forms a deodorization channel between the inner cavity of the inner liner 1 and the drying mechanism 3, and the air outlet 23 forms a drying channel between the inner cavity of the inner liner 1 and the drying mechanism 3.

[0039] When the aforementioned channel structure is activated for drying, the drying mechanism 3 on the bottom surface of the inner liner begins to work, sending drying air into the cavity surrounded by the inner liner 1 to dry the tableware. The drying air can gradually spread to the entire inner liner cavity and then be discharged from the air outlet 23 of the ventilation mechanism 2 at the top of the inner liner 1, forming a drying channel. When the aforementioned channel structure is activated for ventilation, outside air can enter the cavity surrounded by the inner liner 1 through the air inlet 22 and gradually diffuse to all parts of the inner liner 1. The odorous air that has been left in the inner liner 1 for a long time is discharged through the drying mechanism 3, forming a deodorizing channel, thus achieving the effect of purifying and ventilating the air in the cavity.

[0040] like Figure 1 As shown, in the channel structure provided by the first aspect of this utility model, the drying mechanism 3 and the ventilation mechanism 2 are far apart in height, so the drying air can fully spread to all parts of the inner liner 1 and then be discharged from the air outlet, resulting in high drying efficiency and less chance of incomplete drying in the corners of the cavity. Similarly, the ventilation air can also fully spread to all parts of the inner liner 1 and then be discharged from the drying mechanism 3, resulting in good odor removal. The above-mentioned ventilation system can achieve drying and deodorization functions through the air inlet and air outlet, without the need for a valve structure, making the air path simpler.

[0041] Specifically, the ventilation mechanism 2 and the drying mechanism 3 can be staggered in the horizontal direction to extend the movement path of the gas between the ventilation mechanism 2 and the drying mechanism 3. For example, the ventilation mechanism 2 and the drying mechanism 3 can be diagonally distributed in the horizontal direction, so as to extend the movement path of the gas in the inner liner 1 as much as possible and ensure that the gas fills the inner liner 1 in a short time.

[0042] In addition, when one of the air inlet 22 and the air outlet 23 is in use, the other can be closed to ensure the unobstructed flow of the deodorization channel and the drying channel.

[0043] In alternative implementations, such as Figure 2 As shown, the ventilation mechanism 2 also includes a first fan 21, which is connected to the air inlet 22 to blow air into the inner liner 1 through the air inlet 22.

[0044] When the aforementioned channel structure is activated for drying, the drying mechanism 3 begins operation, sending drying air into the cavity surrounded by the inner liner 1 to dry the tableware. At this time, the air outlet 23 in the ventilation mechanism 2 opens, and the air inlet 22 closes, allowing the drying air inside the inner liner 1 to be discharged through the air outlet 23. When ventilation is activated, the air outlet 23 in the ventilation mechanism 2 closes, the air inlet 22 opens, and the first fan 21 starts operating. Outside air enters the inner liner 1 through the first fan 21 and the air inlet 22, while lingering odors in the inner liner 1 are discharged through the drying mechanism 3, achieving the effect of purifying and ventilating the air inside the cavity.

[0045] When the above-mentioned channel structure does not require drying or air exchange, both the air outlet 23 and the air inlet 22 can be in a closed state.

[0046] In alternative implementations, such as Figure 1 As shown, in order to make the replacement gas entering the inner liner 1 cleaner, the channel structure also includes a filter assembly 4. The filter assembly 4 is connected to the air inlet end of the air inlet 22. The filter assembly 4 can remove impurities in the air, making the gas discharged into the inner liner 1 from the air inlet 22 cleaner.

[0047] The filter assembly 4 can be set between the first fan 21 and the air inlet 22, or it can be set upstream of the air inlet end of the first fan 21. In other words, the position of the filter assembly 4 is not specifically limited, and it can be set anywhere that can filter the gas entering the air inlet 22.

[0048] In alternative implementations, such as Figure 2 As shown, the filter assembly 4 includes a housing 41 and multiple filter layers 42, wherein:

[0049] The housing 41 can be detachably connected to the inner liner 1 to facilitate the replacement of the filter assembly 4 by the user, thereby improving the ease of use and user experience.

[0050] The multi-layer filter layer 42 is located inside the box 41 and is distributed sequentially along the gas flow direction inside the box 41, thereby filtering the gas inside the box 41 layer by layer.

[0051] The air inlet 22 is connected to the space inside the housing 41 so that the air inlet 22 can receive the gas filtered by the housing 41.

[0052] In the above embodiments, there can be a variety of ways to detachably connect the box body 41 and the inner liner 1, such as connecting the box body 41 and the inner liner 1 with screws, snapping the box body 41 and the inner liner 1 together, etc. In other words, any method that can achieve a detachable connection between the box body 41 and the inner liner 1 is acceptable.

[0053] The multi-layer filter layer 42 can be of multiple types, such as HEPA filter for sterilization, PM2.5 adsorption pre-filter, or combined filter.

[0054] In an optional embodiment, the air inlet 22 is provided with a first valve for controlling the opening and closing of the air inlet 22, and the air outlet 23 is provided with a second valve for controlling the opening and closing of the air outlet 23.

[0055] The first valve can control the opening and closing of the air inlet 22 independently, and the second valve can control the opening and closing of the air outlet 23 independently.

[0056] The first and second valves can be manual valves or solenoid valves, etc.

[0057] The first and second valves mentioned above can be of the same type or different types.

[0058] In alternative implementations, such as Figure 2 As shown, the ventilation mechanism 2 also includes a driver and a transmission assembly connected to the driver. The transmission assembly cooperates with the air inlet 22 and the air outlet 23. The driver is used to drive the transmission assembly to selectively open the air inlet 22 and the air outlet 23 or close the air inlet 22 and the air outlet 23.

[0059] The above-described embodiment achieves single-opening air inlet 22, single-opening air outlet 23, and closing of air inlet 22 and air outlet 23 through a single power source. Compared with the above-described embodiment, it does not require separate control of the first valve and the second valve, making the control process simpler.

[0060] The driver can be a rotary motor, which drives the transmission component to rotate to change the opening and closing state of the air inlet 22 and the air outlet 23. Alternatively, the driver can be a linear motion mechanism such as a cylinder or hydraulic cylinder, which drives the transmission component to move linearly to change the opening and closing state of the air inlet 22 and the air outlet 23.

[0061] In alternative implementations, such as Figure 2 and Figure 4 As shown, the transmission assembly includes a driving element 24 and a driven disc 25;

[0062] The driving component 24 is connected to the power output end of the driver and rotates under the drive of the driver;

[0063] The end face of the driven plate 25 is tightly fitted to the air inlet 22 and the air outlet 23 to prevent gas from overflowing from the gap between the driven plate 25, the air inlet 22 and the air outlet 23. The driven plate 25 is connected to the driving member 24 and rotates relative to the air inlet 22 and the air outlet 23 under the drive of the driving member 24.

[0064] In use, the driving element 24 drives the driven disc 25 to rotate, causing the driven disc 25 to rotate relative to the air inlet 22 and the air outlet 23. For example... Figure 4 As shown, the driven disk 25 may have an opening 251. During the rotation of the driven disk 25, the opening 251 may be aligned with the air inlet 22, at which time the air inlet 22 is in the open state and the air outlet 23 is in the closed state; the opening 251 may also be aligned with the air outlet 23, at which time the air outlet 23 is in the open state and the air inlet 22 is in the closed state; the opening 251 may also not be aligned with either the air inlet 22 or the air outlet 23, in which case both the air inlet 22 and the air outlet 23 are closed.

[0065] The above-mentioned transmission assembly has a simple structure, and the opening and closing states of the air inlet 22 and the air outlet 23 can be changed by rotating the driven plate 25.

[0066] Specifically, the driven disk 25 can mesh with the driving element 24, the driving element 24 can be a gear, and the driven disk 25 can be regarded as an incomplete gear.

[0067] In addition, the air inlet 22 and the air outlet 23 can be formed on the inner liner 1. The center of the driven plate 25 can rotate and cooperate with the inner liner 1. One end face of the driven plate 25 is attached to and sealed with the inner wall of the inner liner 1, covering the air inlet 22 and the air outlet 23. By rotating the driven plate 25 relative to the inner liner 1, the opening 251 can be adjusted to be aligned with the air inlet 22, the air outlet 23, or the inner surface of the inner liner 1, thereby sealing the air inlet 22 and the air outlet 23.

[0068] To ensure the sealing between the driven plate 25 and the air inlet 22, and between the driven plate 25 and the air outlet 23, the end face of the driven plate 25 facing the air inlet 22 and the air outlet 23 may have a sealing gasket.

[0069] In addition, the opening and closing of the air inlet 22 and the air outlet 23 can be adjusted manually or automatically.

[0070] In an optional embodiment, a temperature sensor or a gas sensor is provided inside the inner liner 1, or both a temperature sensor and a gas sensor are provided inside the inner liner 1.

[0071] The temperature sensor is connected to the ventilation mechanism 2 via a controller, and the gas sensor is also connected to the ventilation mechanism 2 via a controller.

[0072] In the above embodiments, the temperature sensor can detect the temperature inside the inner liner 1, and the controller can automatically control the on / off state of the air inlet 22 and air outlet 23 in the ventilation mechanism 2 according to the temperature. The gas sensor can detect the concentration of polluting gas inside the inner liner 1, and the controller can automatically control the on / off state of the air inlet 22 and air outlet 23 in the ventilation mechanism 2 according to the concentration of polluting gas.

[0073] Of course, in some other implementations, temperature and gas sensors may not be required. Users can also set the ventilation time to automatically activate the ventilation function within a certain time period, purify the air odor in the cavity of such kitchen utensils or cleaning appliances that have been stored for a long time, keep the air inside the cavity clean and dry, and prevent the growth of bacteria.

[0074] In alternative implementations, such as Figure 3 As shown, the drying mechanism 3 includes a vent pipe 31, a second fan 32, and a heating component 33. The second fan 32 is connected to the vent pipe 31 and is used to discharge outside air into the inner liner 1 through the vent pipe 31. The heating component 33 is connected to the vent pipe 31 and is used to heat the gas discharged into the inner liner 1 through the vent pipe 31.

[0075] During use, the second fan 32 draws outside air into the vent pipe 31, and the heating element 33 heats the gas discharged into the inner liner 1 through the vent pipe 31, giving the gas a certain temperature and thus drying the tableware inside the inner liner 1 more quickly. During deodorization, lingering odors in the inner liner 1 can be expelled through the vent pipe 31.

[0076] The heating component 33 can be located upstream of the second fan 32 or downstream of the second fan 32. In other words, the location of the heating component 33 is not specifically limited. It can be located anywhere that can heat the gas discharged from the vent pipe 31 into the inner liner 1.

[0077] The heating assembly 33 may include a heating wire for heating the gas, or a heating tube for heating the gas, etc.

[0078] In alternative implementations, such as Figure 1 As shown, the height of the drying mechanism 3 is lower than that of the ventilation mechanism 2, so that the drying air blown out by the drying mechanism can be discharged from the ventilation mechanism 2.

[0079] In an optional embodiment, the drying mechanism 3 further includes a third valve for controlling the airflow within the vent pipe 31.

[0080] When the above-mentioned channel structure does not require drying or ventilation, the vent pipe 31, the air outlet 23 and the air inlet 22 can all be in a closed state.

[0081] The third valve can be a manual valve or a solenoid valve, etc.

[0082] It should be noted that this channel structure is not limited to kitchenware storage appliances, such as sterilizers and dishwashers, but is also applicable to other similar appliances or equipment that require drying, purification, and ventilation.

[0083] A second aspect of this utility model provides a dishwasher, which includes the aforementioned channel structure with odor removal and drying functions.

[0084] The dishwasher provided in the second aspect of this utility model has the channel structure provided in the embodiment of the first aspect of this utility model, thereby having all the beneficial effects of the channel structure provided in the embodiment of the first aspect of this utility model.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
