Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, and in particular relates to an external circulation drying structure and a tableware cabinet that take into account multiple cavities. 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, using a fan to dry the tableware in the bowl basket is one of the most common drying methods. This drying method easily forms a small-scale wind path with the air outlet directly pointing to the air inlet. Coupled with the barrier effect of the tableware itself, the hot air has a relatively narrow range of action, the temperature field is unevenly distributed, and there are drying dead corners, making the drying operation less effective and more inefficient.

[0004] At the same time, for double-layer or even multi-layer drying cabinets, how to balance the drying effects between different drying chambers and the selection of drying functions are also technical problems that need to be solved urgently. Summary of the invention

[0005] In order to solve the above technical problems, the present application further improves the drying structure in the multi-cavity cupboard, in order to obtain a fast, uniform and stable drying and disinfection effect. One of the purposes of the present invention is to provide an external circulation drying structure that takes into account multiple cavities, and the second purpose is to provide a corresponding tableware cabinet.

[0006] The specific technical solution is described below:

[0007] The multi-cavity external circulation drying structure includes a drying fan and at least two layers of cavities, each layer of the cavity is provided with a bowl rack, and also includes:

[0008] A drying air duct, the drying air duct comprising a distribution air duct and a conveying air duct;

[0009] The distribution air duct is divided into a plurality of sub-air ducts, each cavity corresponds to at least one of the sub-air ducts, and the sub-air duct is provided with a distribution port connected to the corresponding cavity, and the sub-air duct is connected to the gas output by the drying fan through a switch valve;

[0010] The conveying air duct has an air collecting port and a plurality of air outlets;

[0011] 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.

[0012] In the above technical solution, sub-air ducts corresponding to different cavities are arranged in the distribution air duct, and corresponding switching valves are coordinated to realize the air path for the drying gas to dry different cavities. This air path can be controlled to be switched relatively independently, so as to realize controllable drying in different cavities.

[0013] At the same time, the outlets of the drying air are dispersedly and directionally arranged in different drying areas on the bowl rack, so that the tableware to be dried is located on the inevitable path of the flow path of the drying gas, thereby obtaining an efficient drying effect.

[0014] Preferably, the distribution air duct is a flat air duct extending vertically, and the gas output by the drying fan has a flow path from bottom to top in the distribution air duct. When the switching valve is opened, the corresponding sub-air duct is located on the flow path.

[0015] 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 to correspond to the position of the corresponding bowl rack. The sub-air duct is located above the drying fan, and can also conform to the natural law of hot air flow rising, making the drying more efficient.

[0016] Preferably, the distribution port has a distribution groove extending horizontally, and a plurality of distribution air outlet through holes are spaced apart at the distribution groove.

[0017] In the above technical solution, the horizontally extending distribution groove is convenient for processing, and it is also convenient for the corresponding air collecting port to be set as a simple long strip shape, which is relatively space-saving.

[0018] Preferably, it includes two layers of cavities, namely an upper cavity and a lower cavity located below the upper cavity.

[0019] Further preferably, the lower cavity corresponds to two of the sub-air ducts, and these two sub-air ducts are arranged on both sides of the distribution air duct in the horizontal direction and in the middle and / or lower part of the distribution air duct in the vertical direction.

[0020] An air inlet channel is arranged between the two sub-air ducts, and the air inlet channel is communicated with the sub-air duct corresponding to the upper cavity.

[0021] Further preferably, a switching valve is arranged at the lower part of each of the two sub-air ducts corresponding to the lower cavity; a switching valve is arranged at the air inlet channel.

[0022] In the above technical solution, the air inlet channel is arranged vertically, which can conform to the trend of the drying air flow and does not hinder its entry into the sub-air duct corresponding to the upper cavity.

[0023] Preferably, adjacent sub-air ducts are separated by an air duct partition board.

[0024] Sideboard, including a cabinet door and a cabinet body. The cabinet body has at least two layers of cavities. There is a moisture discharge gap between the cabinet door and the cabinet body. The bowl rack structure described in any of the above technical solutions is arranged in the cabinet body.

[0025] Preferably, a disinfection device, such as an ozone generator, an infrared irradiation device, etc., is arranged in the cabinet body.

[0026] In summary, the technical solution of the present invention has the following main beneficial effects:

[0027] Compared with the prior art, in the present invention, sub-air ducts corresponding to different cavities are arranged in the distribution air duct, and corresponding switching valves are coordinated to obtain an air path for drying different cavities with drying gas. The air path can be controlled to be switched relatively independently, so as to realize controllable drying in different cavities.

[0028] At the same time, the outlets of the drying air are dispersedly and directionally arranged in different drying areas on the bowl rack, so that the tableware to be dried is located on the inevitable path of the flow path of the drying gas, and thus an efficient drying effect is obtained.

[0044] The present invention is further explained in combination with the embodiments:

[0045] The core technical problem faced by the technical solution of the embodiments of the present application stems from the inventors' accurate understanding of the prior art. Therefore, how to improve and balance the drying efficiency and effect of the fan inner circulation drying basket in the multi-layer drying cavity is a technical problem that the inventors urgently need to solve.

[0046] It should be noted that the embodiments do not constitute a limitation on the protection scope of the claims of the present invention. All technical solutions that can be reasonably expected by those skilled in the art according to the technical concepts provided / proven by the embodiments should be covered by the protection scope of the claims of the present invention.

[0047] The embodiments are described in detail as follows:

[0048] In the prior art, for double-layer or even multi-layer drying cabinets, it is a rather difficult technical problem to balance the drying effect and select the drying function between different drying cavities.

[0049] For this reason, this embodiment provides an external circulation drying structure that takes into account multiple cavities. Please first refer to the attached Figures 1 to 5, the drying structure includes a drying fan 1.1 and two cavities distributed vertically, namely an upper cavity and a lower cavity located below the upper cavity. A partition is provided between the upper cavity and the lower cavity. A bowl rack is arranged in each cavity, and the bowl rack enters and exits the cabinet of the drying cabinet in a drawer - like manner;

[0050] Importantly, the drying structure further includes a drying air duct 1.3, and the drying air duct 1.3 includes a distribution air duct 1.31 and a conveying air duct 1.32;

[0051] Among them, several sub - air ducts 1.312 are separated on the distribution air duct 1.31. The upper cavity corresponds to one of the upper sub - air ducts 1.312, and the lower cavity corresponds to two of the lower sub - air ducts 1.312; A distribution port 1.311 communicating with the corresponding cavity is opened on each sub - air duct 1.312, and each sub - air duct 1.312 is connected to the gas output by the drying fan 1.1 through a switching valve 1.313. The switching valve 1.313 can be a butterfly valve and is controlled by a motor to open / close. Please refer to the appendix Figures 5 to 7 , when the switching valves 1.313 of the sub - air ducts 1.312 corresponding to the upper cavity and the lower cavity are both in the open state, the upper and lower cavities are heated and dried simultaneously; When the switching valve 1.313 of the sub - air duct 1.312 corresponding to the upper cavity is in the open state and the switching valves 1.313 of the two sub - air ducts 1.312 corresponding to the lower cavity are in the closed state, the upper cavity is heated and dried, and the lower cavity is not heated and dried; When the switching valves 1.313 of the two sub - air ducts 1.312 corresponding to the lower cavity are in the open state and the switching valve 1.313 of the sub - air duct 1.312 corresponding to the upper cavity is in the closed state, the lower cavity is heated and dried, and the upper cavity is not heated and dried;

[0052] Adjacent sub - air ducts 1.312 are separated by an air duct partition 1.314. The air duct partition 1.314 and the periphery of the distribution air duct 1.31 enclose and separate to form the areas where each sub - air duct 1.312 is located;

[0053] The conveying air duct 1.32 has an air inlet 1.321 and several air outlets 1.322;

[0054] During drying, the air inlet 1.321 is docked and communicated with the corresponding distribution port 1.311, and several air outlets 1.322 are arranged in different drying areas on the bowl rack.

[0055] The technical solution of this embodiment sets sub - air ducts 1.312 corresponding to different cavities in the distribution air duct 1.31 and cooperates with the corresponding switching valves 1.313 to realize the air path for drying gas to different cavities. This air path can be controlled to switch relatively independently, so as to achieve controllable drying in different cavities;

[0056] Meanwhile, the air outlets 1.322 of the drying air are dispersedly and directionally arranged in different drying areas on the bowl rack, so that the tableware to be dried is located on the necessary path of the flow path of the drying gas, thereby obtaining an efficient drying effect;

[0057] Specifically, please refer to the appendix again Figure 8 , air enters from the air inlet 1.2 on the back panel. The drying fan 1.1 first blows out hot air through the air outlet. After drying, the hot air basically discharges through the moisture discharge gap between the cabinet door and the cabinet body; a heating pipe is arranged at the air outlet of the drying fan 1.1 to heat the output air flow to form hot air;

[0058] In this embodiment, the drying air duct 1.3 in the cabinet is used to solve the problems of low drying efficiency and poor effect in a single-layer cavity.

[0059] The drying air duct 1.3 conducts the gas output by the drying fan 1.1 to different areas on the bowl rack. The gas output by the drying fan 1.1 is transported to each dispersed area of the bowl basket through the drying air duct 1.3 to dry each tableware. The drying flow path dispersedly and directionally arranges the air outlets 1.322 at the bottom of the bowl basket, so that the tableware to be dried is located on the necessary path of the flow path of the drying gas. 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 field more evenly distributed under the drive of the air flow, and then being able to act on each area in the bowl basket to avoid the generation of dead corners of action and improve the drying efficiency and effect.

[0060] In a preferred embodiment, the distribution air duct 1.31 is a vertically extending flat air duct. The distribution air duct 1.31 is arranged on a side wall closer to the inside of the cabinet body. The gas output by the drying fan 1.1 flows upward in the distribution air duct 1.31. When the on-off valve 1.313 is opened, the corresponding sub-air duct 1.312 is also located on the flow path of the hot air;

[0061] The distribution port 1.311 in this embodiment has a laterally extending distribution groove 1.311a, and a number of distribution air outlet through holes 1.311b are spacedly arranged at the distribution groove 1.311a.

[0062] 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, playing a role in stabilizing the pressure. At the same time, a side wall of the distribution air duct 1.31 close to the inside of the cabinet body provides a setting basis for the distribution port 1.311 at a suitable position. The conveying air duct 1.32 then transports the gas distributed from the distribution port 1.311 to different drying areas of the bowl basket for drying;

[0063] 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. The sub-air duct 1.312 is located above the drying fan 1.1, and can also conform to the natural law of hot air flow rising, making the drying more efficient;

[0064] The horizontally extending distribution slot 1.311a is convenient for processing, and also enables the corresponding air collecting port 1.321 to be set in a simple long strip shape, thereby obtaining a structure that basically covers the distribution slot 1.311a. On the premise of improving the gas collection effect, it is relatively space-saving;

[0065] Furthermore, for a drying cabinet with multiple chambers, the flat distribution air duct 1.31 has a long extension distance, so there is a potential risk of deformation of the side plate of the distribution air duct 1.31. At this time, the air duct partition 1.314 not only serves to separate the individual sub-air ducts 1.312, but also reinforces the side plate of the distribution air duct 1.31 and enhances the stability of its shape.

[0066] In a preferred embodiment, the lower cavity corresponds to two sub-air ducts 1.312. These two sub-air ducts 1.312 are arranged on both sides of the distribution air duct 1.31 in the horizontal direction and in the middle and lower parts of the distribution air duct 1.31 in the vertical direction. An air inlet channel 1.315 is arranged between these two sub-air ducts 1.312. The air inlet channel 1.315 is connected to the sub-air duct 1.312 of the corresponding upper cavity. A switching valve 1.313 is provided at the lower part of each of the two sub-air ducts 1.312 corresponding to the lower cavity, and a switching valve 1.313 is provided at the air inlet channel 1.315. The switching valve 1.313 provided at the air inlet channel 1.315 is used to control the inflow of hot air into the upper cavity;

[0067] The air inlet channel 1.315 in this embodiment is vertically arranged, which can conform to the trend of the drying air flow and does not hinder its entry into the sub-air duct 1.312 corresponding to the upper cavity. At the same time, please refer specifically to the attached Figure 5 and 6 , a horizontally distributed strip-shaped distribution port 1.311 is arranged on the air inlet channel 1.315, and a butterfly valve switching valve 1.313 is arranged on the air inlet channel 1.315. A baffle is arranged horizontally on the butterfly valve switching valve 1.313. The baffle rotates axially under the drive of the motor, so that when the baffle blocks the distribution port 1.311, the air inlet channel 1.315 is exactly in a flowing state, and the hot air enters the sub-air duct 1.312 corresponding to the upper cavity. When the baffle blocks the air inlet channel 1.315, the distribution port 1.311 is exactly in a flowable state, and the hot air enters the lower cavity after entering the distribution port 1.311;

[0068] When the upper and lower cavities are in the state of simultaneous air intake, the baffle blocks the distribution port 1.311, enabling more hot air to flow towards the upper cavity. At this time, it is possible to form a drying mode with functional differentiation, where the upper cavity dries tableware that is difficult to dry, and the lower cavity dries tableware that is easier to dry. This can provide users with a drying mode with functional differentiation, reasonably and specifically arrange various tableware in different cavities, thereby improving the utilization rate of hot air and enhancing the drying efficiency.

[0069] Meanwhile, in this embodiment, the sub-air duct 1.312 corresponding to the upper cavity expands the volume of the air duct compared to the air intake channel 1.315, and the upper cavity further expands the volume relative to the sub-air duct 1.312. Thus, a drying path with a gradually increasing volume is formed. On this drying path, the pressure and flow rate of the drying gas both show a trend of continuous change with a relatively high amplitude. In order to correspond to this change, the gas will inevitably tend to a more turbulent flow state. Therefore, it can strengthen the convection of the fluid, and further improve the drying effect in the upper cavity, making the upper cavity particularly suitable for tableware that is difficult to dry (such as tableware with a slightly complex structure, dead corners, or a deep inner barrel).

[0070] In a further preferred embodiment, the shelves and partition structures in the bowl rack of the bowl basket are made of hollow metal pipes, such as pipes made of 316L stainless steel. This hollow metal pipe is part of the above-mentioned conveying air duct 1.32, and the air outlet 1.322 is arranged on the bowl rack, which can be an open through hole or an additionally provided directional branch. That is to say, the conveying air duct 1.32 in this embodiment exists as part of the structure of the bowl basket, which can save space and facilitate the setting of different drying positions. In this technical solution, due to the transmission of hot air, the shelves and partition structures of the bowl rack also become the targets to be heated. Taking the bowl rack as a carrier for collecting heat can further reduce the unnecessary loss of heat (especially under the premise that external circulation drying is more energy-consuming). At this time, the heat can be distributed to all areas that the bowl rack can radiate through the heat radiation of the bowl rack itself, thereby covering the storage range of tableware in another form. The bowl rack itself will also be dried, and the tableware placed on the bowl rack also becomes placed on a "dry frame with a certain temperature". Even if there are inevitably some flow dead zones where the gas cannot reach (such as the inside of some special-shaped tableware), the heat of the bowl rack itself can still act on the tableware through heat radiation and heat conduction, and ensure that the tableware in this part is dried.

[0071] 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, which is convenient to correspond to the position of the corresponding bowl rack.

[0072] In a preferred embodiment, a plurality of air outlets 1.322 are spaced apart and distributed at the lower part of each layer of the bowl rack, and the air outlets 1.322 have an output direction facing upward.

[0073] In this embodiment, the air outlets 1.322 can form an upward blowing air flow, which is convenient for acting on the tableware placed on the bowl rack to cover each drying area of the bowl rack and improve the drying effect.

[0074] Please continue to refer to the appendix Figures 9 to 10 In a further preferred embodiment, a plurality of air outlets 1.322 include alternately arranged bottom-layer air outlets 1.322a and middle-layer air outlets 1.322b;

[0075] In the technical solution of this embodiment, whether it is the bottom-layer air outlet 1.322a or the middle-layer air outlet 1.322b, once the gas flows out, it will diffuse in the flow direction. For the bottom-layer air outlet 1.322a, after the gas flows out, it can act better 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 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.

[0076] 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, which is convenient for gas collection and forms an accelerating air flow. At the same time, it also allows certain processing / operation errors in each component, and still can collect gas in the presence of this error, improving the drying / blowing effect.

[0077] This embodiment also relates to a tableware cabinet, which includes a cabinet door and a cabinet body. The cabinet body has at least two layers of cavities. There is a moisture exhaust gap between the cabinet door and the cabinet body. The bowl rack structure described in any of the above embodiments is provided in the cabinet body. Preferably, a common disinfection device such as an ozone generator, an infrared irradiator, etc. is additionally provided in the cabinet body.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example.
