Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and particularly relates to a bowl rack structure and a tableware cabinet for efficient internal circulation drying. Background Art

[0002] Disinfection cabinets and drying cabinets with bowl baskets are one of the most commonly used household appliances in the kitchen.

[0003] Among them, the drying of tableware on the bowl basket by a blower is divided into two methods: external exhaust type and internal circulation type. In the external exhaust type drying method, the blower blows out hot air, and after the hot air dries, it is discharged outside the bowl cabinet. This drying method has a better moisture discharge effect, but the heat is also discharged synchronously, resulting in large heat loss, high energy consumption, and slow temperature rise. In the internal circulation drying method, the blower blows out hot air, and after the hot air dries, it flows into the air inlet in the bowl cabinet and is then cycled out by the blower. The water vapor in this drying method is usually discharged through the gaps around the bowl cabinet. The moisture discharge speed is not as fast as that of the external exhaust type drying method, but the vast majority of the heat output by the blower is recycled and retained. Therefore, it has the advantages of small heat loss, low energy consumption, and fast temperature rise.

[0004] In the above internal circulation drying mode, since both the air outlet and the air inlet of the blower are arranged inside the bowl cabinet, it is easy to form a small-range air path where the air outlet directly points to the air inlet. Coupled with the blocking effect of the tableware itself, the action range of the hot air is relatively narrow, the temperature field distribution is uneven, there are drying dead corners, and the drying operation effect is poor and inefficient. Summary of the Invention

[0005] In order to solve the above technical problems, the present application further improves the drying structure in the bowl cabinet in order to obtain a fast, uniform, and stable drying and disinfection effect. One of the purposes of the present invention is to provide a bowl rack structure for efficient internal circulation drying, and the second purpose is to provide a corresponding tableware cabinet.

[0006] The specific technical solutions are described below:

[0007] A bowl rack structure for efficient drying, including a bowl rack, a drying blower, and an air inlet of the drying blower, and further including:

[0008] A circulating air component having a drying air duct;

[0009] The drying air duct includes a distribution air duct and a conveying air duct;

[0010] A distribution port is opened on the distribution air duct, and the gas output by the drying blower is conducted to the distribution port through the distribution air duct;

[0011] The conveying air duct has a collecting air port and a plurality of air outlets;

[0012] During drying, the air collecting port is connected to and communicates with the distribution port, and a plurality of the air outlets are arranged in different drying areas on the dish rack.

[0013] In the above technical solution, the air outlets are dispersedly and directionally arranged at the bottom of the bowl basket, so that the dishes to be dried are located on the necessary path of the drying gas flow path, thereby obtaining a uniform temperature field and an efficient drying effect;

[0014] The air output by the drying fan is transported to several different areas of the bowl basket through the drying air duct, and then returns to the drying fan through the air inlet, forming an internal circulation drying flow path;

[0015] The drying flow path expands the convection flow of gas to each area to be dried in the bowl basket, so that the heat field is more evenly distributed under the drive of the airflow, and can then act on each area in the bowl basket, avoiding the formation of dead corners and improving the drying efficiency and effect.

[0016] Preferably, the gas output by the drying fan has a flow path that enters at least part of the internal circulation;

[0017] The flow path of at least part of the internal circulation includes: the gas output by the drying fan enters the distribution air duct, is output from the distribution port to the air collecting port, is output from the plurality of air outlets to the area to be dried, enters the air inlet and returns to the drying fan.

[0018] In the above technical solution, the distribution duct provides a space for the gas output by the drying fan to flow and transport, which plays a role in stabilizing the pressure. At the same time, the distribution duct provides a basis for setting the distribution port at a suitable position, and the delivery duct then transports the gas distributed from the distribution port to different drying areas of the bowl basket for drying;

[0019] The bowl rack of the bowl basket can be made of hollow pipes. The bowl rack is a part of the above-mentioned conveying air duct, and the air outlet is arranged on the bowl rack, which can save space and facilitate the setting of different drying positions;

[0020] At the same time, the bowl rack becomes the first target to be heated due to the transmission of hot air. The bowl rack becomes a carrier for collecting heat, reducing unnecessary heat loss. The heat is distributed to various areas that the bowl rack can reach through the heat conduction of the bowl rack itself, thereby covering the storage range of tableware. The bowl rack itself will also be in a dry state, and the tableware placed on the bowl rack is equivalent to being placed on a drying frame "with a certain temperature". The heat of the bowl rack itself can still be transmitted to the tableware through heat radiation and heat conduction, and ensure that the part of the tableware on it is dried.

[0021] Further preferably, the distribution air duct is a vertically extending flat air duct, and the gas output by the drying fan has a flow path from bottom to top in the distribution air duct.

[0022] In the above technical solution, the flat distribution air duct enables it to be arranged on one side of the bowl basket without causing spatial interference to the bowl rack. At this time, the distribution port is opened on the side wall of the distribution air duct, which is convenient for corresponding to the position of the corresponding bowl rack.

[0023] Further preferably, the number of layers of the bowl rack is at least two, and one of the above-mentioned conveying air ducts is arranged at each layer of the bowl rack, and each of the conveying air ducts is connected and communicated with one of the distribution ports.

[0024] Further preferably, the air inlet is arranged in the middle of the distribution air duct, and the distribution ports are arranged at intervals above and / or below the air inlet.

[0025] In the above technical solution, whether it is the upper or lower bowl basket, a reflux air path with a certain distance in the vertical direction will be formed after hot air drying, so that the drying flow path has a more sufficient and wider acting range of the flow area. At the same time, the air inlet and the distribution port will not interfere with each other in position, and the flow paths of the hot air output and reflux in roughly opposite directions are not likely to affect each other's flow.

[0026] Further preferably, several of the above-mentioned air outlets are distributed at intervals at the lower part of each layer of the bowl rack, and at least part of the output direction of the air outlet is upward.

[0027] In the above technical solution, at least part of the output direction of the air outlet being upward can form an upward blowing air flow, which is convenient for acting on the tableware placed on the bowl rack and improving the drying effect.

[0028] Further preferably, several of the above-mentioned air outlets include alternately arranged bottom-layer air outlets and middle-layer air outlets.

[0029] In the above technical solution, whether it is the bottom-layer air outlet or the middle-layer air outlet, the gas will diffuse in the flow direction once it flows out. For the bottom-layer air outlet, after the gas flows out, it can act well on the lower position of the tableware. However, due to the further diffusion of the gas, the drying effect on the upper position of the tableware will be relatively weak. Based on this understanding, the middle-layer air outlet with a higher outlet height is set, aiming to compensate for the drying effect on the upper position of the tableware, so as to obtain a comprehensive drying effect and a basically synchronous drying time, and further avoid the drying dead angle on the upper part of the tableware.

[0030] Further preferably, the air collecting port has an air collecting channel that gradually expands along the direction pointing to its corresponding distribution port, facilitating the collection of gas and forming an accelerating air flow to enhance the drying / blowing effect.

[0031] The sideboard includes a cabinet door and a cabinet body. There is a moisture exhaust gap between the cabinet door and the cabinet body, and the bowl rack structure described in any of the above technical solutions is arranged inside the cabinet body.

[0032] Preferably, a disinfection device such as an ozone generator, an infrared irradiation device, etc. is arranged inside the cabinet body.

[0033] In summary, the technical solution of the present invention has the following main beneficial effects:

[0034] Compared with the prior art, the technical solution of the present invention disperses and directionally arranges the air outlets at the bottom of the bowl basket, obtaining a uniform temperature field and an efficient drying effect.

[0035] Furthermore, the distribution air duct plays a role in stabilizing the pressure and provides a setting basis for the distribution port. The bowl rack of the bowl basket, as a part of the above-mentioned conveying air duct, can save space and is convenient for setting different drying positions.

[0036] Even further, the flat-shaped distribution air duct can be arranged on one side of the bowl basket without causing spatial interference to the bowl rack. The distribution ports are arranged at intervals above and / or below the air inlet, so that the drying flow path has a more sufficient and wider acting range of the flow area.

[0037] Even further or more detailed beneficial effects will be described in combination with specific embodiments in the specific implementation manners. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The present invention will be further explained in combination with embodiments:

[0047] The core technical problem faced by the technical solution of the embodiment of the present application stems from the accurate understanding of the prior art by the inventor. Therefore, how to improve the drying efficiency and effect of the fan inner circulation drying bowl basket is a technical problem that the inventor urgently needs to solve.

[0048] It should be noted that the embodiments do not constitute a limitation on the protection scope of the claims of the present invention. According to the technical concept provided / proven by the embodiments, all technical solutions that can be reasonably expected by those skilled in the art should be covered by the protection scope of the claims of the present invention.

[0049] The embodiments are described in detail as follows:

[0050] Please first refer to the attached Figure 1 , attached Figure 1 shows the internal structure schematic diagram of a sideboard that uses a fan to dry tableware in an inner circulation manner in the prior art. As Figure 1 can be seen, the fan is arranged on the inner side wall of the bowl basket closer to the inside, its air inlet 1.2 is in the middle, and the air outlet is around the air inlet 1.2. In this inner circulation drying method, the fan first blows out hot air through the air outlet, and after the hot air is dried, it converges into the air inlet 1.2 in the middle of the sideboard and is then cycled out by the fan. This drying method has the advantages of small heat loss, low energy consumption, and fast temperature rise;

[0051] At the same time, in the above-mentioned inner circulation drying mode, since both the air outlet and the air inlet 1.2 of the fan are arranged inside the sideboard and the distance between them is small, it is easy to form a small-scale air path directly pointing from the outlet to the air inlet 1.2. Coupled with the blocking effect of the tableware itself, the action range of the hot air is relatively narrow, the temperature field distribution is uneven, and there are large drying dead angles for the tableware in the part far from the air outlet, resulting in poor drying operation effect and low efficiency.

[0052] To solve the above technical problems, this embodiment first relates to a bowl rack structure for efficient inner circulation drying:

[0053] Please refer to the attached Figures 2 to 6, the bowl rack structure includes two layers of bowl racks, upper and lower, and a drying fan 1.1 arranged in the middle of the cabinet body. A heating pipe is arranged at the air outlet of the drying fan 1.1 to output hot air. The bowl racks are telescopically arranged on the cabinet body in a relatively common drawer - type form;

[0054] In this embodiment, a circulating air component in the cabinet body is used to solve the problems of low drying efficiency and poor effect mentioned above.

[0055] The circulating air component includes a drying fan 1.1 and a drying air duct 1.3 that conducts the gas output by the drying fan 1.1 to different areas on the two - layer bowl racks. The air inlet 1.2 of the drying fan 1.1 is arranged in the middle area of the side wall of the bowl cabinet.

[0056] In the technical solution of this embodiment, the gas output by the drying fan 1.1 is conveyed to each dispersed area of the bowl basket through the drying air duct 1.3 to dry each tableware, and then returns to the drying fan 1.1 through the air inlet 1.2, forming an internal - circulation drying flow path. The air outlet 1.322 of this drying flow path is dispersedly and directionally arranged at the bottom of the bowl basket to point to the locations of each tableware, so that the tableware to be dried is on the inevitable path of the drying gas flow. At the same time, the convective flow of the gas is extended to each area to be dried in the bowl basket, making the heat of the hot air more evenly distributed under the drive of the air flow, and then being able to act on each area in the bowl basket, avoiding the generation of dead zones of action, and improving the drying efficiency and effect.

[0057] Further, the drying air duct 1.3 described in this embodiment includes a distribution air duct 1.31 and a conveying air duct 1.32;

[0058] The distribution air duct 1.31 is a flat - shaped air duct extending vertically, arranged on the inner side wall of the cabinet body. The gas output by the drying fan 1.1 has a flow path from bottom to top in the distribution air duct 1.31. A distribution port 1.311 is arranged on one side wall of the distribution air duct 1.31 facing the inside of the drying cavity. The distribution port 1.311 is specifically set in two groups, and each group of distribution ports 1.311 is composed of several through - holes arranged at horizontal intervals;

[0059] The conveying air duct 1.32 has an air collecting port 1.321 and several air outlet ports 1.322. One conveying air duct 1.32 is correspondingly arranged at each layer of the bowl rack. The air collecting port 1.321 is in a long - strip shape, and its extending direction conforms to the through - holes distributed among each group above, so as to cover and collect the air flow output from the distribution port 1.311;

[0060] That is to say, during drying, the air collecting port 1.321 of each conveying air duct 1.32 is connected and communicated with a group of the above - mentioned distribution ports 1.311;

[0061] A plurality of air outlets 1.322 are arranged in different drying areas of the corresponding bowl racks;

[0062] Meanwhile, the air inlet 1.2 is arranged in the middle of the distribution air duct 1.31, and the distribution ports 1.311 are arranged at the upper and lower sides of the air inlet 1.2 at intervals.

[0063] In the technical solution of this embodiment, the gas output by the drying fan 1.1 has a flow path for entering at least partial internal circulation. This flow path includes: the gas output by the drying fan 1.1 enters the distribution air duct 1.31 for flow distribution, then is output from the distribution ports 1.311 to the corresponding air collecting ports 1.321, then is output from the plurality of air outlets 1.322 to the area to be dried, and then flows back into the air inlet 1.2 and returns to the drying fan 1.1. The moisture obtained by drying is discharged through the moisture discharge gaps around the cabinet door.

[0064] In the technical solution of this embodiment, the distribution air duct 1.31 provides a space for the flow and transportation of the gas output by the drying fan 1.1 and plays a role in stabilizing the pressure. At the same time, a side wall of the distribution air duct 1.31 close to the interior of the cabinet provides a setting basis for the distribution ports 1.311 at appropriate positions. The conveying air duct 1.32 then conveys the gas distributed by the distribution ports 1.311 to different drying areas of the bowl basket for drying;

[0065] In the bowl rack of the bowl basket, the shelf and the partition structure are made of hollow metal pipes, such as pipes made of 316L stainless steel. In this embodiment, the hollow metal pipe is used as a part of the above-mentioned conveying air duct 1.32, and the air outlets 1.322 are arranged on the bowl rack, which can be open through holes or additionally arranged directional branches. That is, the conveying air duct 1.32 in this embodiment exists as a part of the structure of the bowl basket. Such a setting can save space and is also convenient for setting different drying positions;

[0066] In this technical solution, due to the transmission of hot air, the shelf and the partition structure of the bowl rack become the first targets to be heated. Taking the bowl rack as a carrier for collecting heat can further reduce the unnecessary loss of heat. At this time, the heat can be distributed to all areas that the bowl rack can reach through the heat conduction of the bowl rack itself, so that it can also cover the storage range of tableware in another form. The bowl rack itself will also present a dry state. The tableware placed on the bowl rack is equivalent to being placed on a "dry framework with a certain temperature". Even if there are inevitably some flow dead zones that the gas cannot reach (such as the inside of some special-shaped tableware), the heat of the bowl rack itself can still reach the tableware through heat radiation and heat conduction and ensure that the tableware in this part is dried;

[0067] Meanwhile, the flat distribution air duct 1.31 enables it to be arranged on one side of the bowl basket without causing spatial interference to the bowl rack. At this time, the distribution port 1.311 is opened on the side wall of the distribution air duct 1.31, facilitating correspondence with the corresponding bowl rack position;

[0068] Furthermore, whether it is the upper or lower bowl basket, after hot air drying, a return air path with a certain spacing in the vertical direction will be formed, making the drying flow path have a more sufficient and wider acting range of the flow area. Moreover, the air inlet 1.2 and the distribution port 1.311 do not interfere with each other in position, and the two flow paths with roughly opposite directions of hot air output and return are not likely to affect each other's flow.

[0069] In a preferred embodiment, several air outlet ports 1.322 are distributed at intervals at the lower part of each layer of the bowl rack, and the air outlet ports 1.322 have an output direction upward, that is, in this embodiment, the air outlet ports 1.322 generally point to the tableware on the bowl basket.

[0070] In this embodiment, the air outlet ports 1.322 can form an upward blowing air flow, facilitating its action on the tableware placed on the bowl rack to cover each drying area of the bowl rack and improving the drying effect.

[0071] In a further preferred embodiment, several air outlet ports 1.322 include alternately arranged bottom-layer air outlet ports 1.322a and middle-layer air outlet ports 1.322b;

[0072] In the technical solution of this embodiment, whether it is the bottom-layer air outlet port 1.322a or the middle-layer air outlet port 1.322b, once the gas flows out, it will diffuse in the flow direction. For the bottom-layer air outlet port 1.322a, after the gas flows out, it can better act on the lower position of the tableware. However, due to the further diffusion of the gas, the drying effect on the upper position of the tableware will be relatively weak. Based on this understanding, this embodiment sets the middle-layer air outlet port 1.322b with a higher outlet height, aiming to compensate for the drying effect on the upper position of the tableware, thereby obtaining a comprehensive drying effect and a basically synchronous drying time, and further avoiding the drying dead angle on the upper part of the tableware.

[0073] In a preferred embodiment, the air collecting port 1.321 has a gradually expanding air collecting channel along the direction pointing to its corresponding distribution port 1.311, facilitating the collection of gas and forming an accelerated air flow. At the same time, it also allows for a certain processing / operation error of each component, and still can collect gas in the presence of this error, improving the drying / blowing effect.

[0074] This embodiment also relates to a sideboard, which includes a cabinet door and a cabinet body. A moisture discharge gap is provided between the cabinet door and the cabinet body. The bowl rack structure described in any of the above embodiments is provided inside the cabinet body. Preferably, a commonly used disinfection device, such as an ozone generator, an infrared irradiator, etc., is additionally provided inside the cabinet body;

[0075] This sideboard can be built into a dishwasher as a drying cabinet or a disinfection cabinet, or can exist as a part of a cabinet body, such as a sideboard, for accommodating tableware.
