Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and more particularly to a circulating drying box. Background Technology

[0002] With urban development, the number of pet owners in cities is constantly increasing, and the demand for pet-related equipment is also growing. After a pet bath, their wet fur often affects indoor hygiene. Drying boxes are commonly used to dry pet fur after bathing. Existing drying box equipment, such as the patent with authorization announcement number CN 212414308 U entitled "A Circulating Air Structure and Dryer of a Dryer," discloses a circulating drying box. However, in this technology, the hot air is directly dissipated to the outside during the internal circulation process without forming a circulation within the drying box. This results in the hot air dissipating quickly to the outside, leading to low utilization. Furthermore, the air inlet is only one air inlet channel at the bottom, resulting in limited air intake and rapid hot air dissipation.

[0003] Therefore, to solve the above-mentioned technical problems, a new technical solution is needed. In particular, a circulating drying oven is required. Summary of the Invention

[0004] This invention addresses the technical problem of poor drying effect and high energy consumption caused by the lack of internal circulation of hot air after initial heating in existing drying ovens on the market, by providing a circulating drying oven.

[0005] To achieve the above objectives, the following technical solution is provided: a circulating drying oven, comprising a shell, a ventilation component and a heating component disposed within the shell, wherein a receiving cavity and a first air inlet cavity are formed within the shell, and a spacer cavity is provided between the receiving cavity and the first air inlet cavity, and a second air inlet cavity is provided at the bottom of the shell, the second air inlet cavity being connected to the receiving cavity, a first air inlet and a second air inlet being provided within the first air inlet cavity, the first air inlet being connected to the receiving cavity, the second air inlet being connected to the second air inlet cavity, the receiving cavity and the spacer cavity being connected through an air outlet, the ventilation component and the heating component being disposed within the first air inlet cavity, the ventilation component connecting the spacer cavity and the first air inlet cavity, a vent hole being provided at the top of the shell, the vent hole being connected to the spacer cavity, and the first air inlet cavity being connected to the outside.

[0006] Preferably, the outer casing includes a front cover, a top cover, a side cover, a rear cover, and a bottom cover. A bottom plate is provided between the bottom cover and the top cover. The bottom plate encloses and forms an accommodating cavity. The bottom plate and the bottom cover enclose and form a second air inlet cavity. A mounting plate and a partition are vertically provided on the bottom cover. The partition and the mounting plate enclose and form a spacer cavity. The ventilation assembly also includes a fan housing. The mounting plate, the rear cover, and the fan housing enclose and form a first air inlet cavity.

[0007] Preferably, the partition is fixedly installed above the mounting plate, a first air inlet is provided below the mounting plate, a second air inlet is provided below the first air inlet, and a heating component is provided in front of the first air inlet; an air inlet is provided on the rear cover, a ventilation hole is provided on the bottom plate, an air outlet is provided on the partition, a vent is provided on the top plate, and the ventilation component is provided through the mounting plate.

[0008] Preferably, a communicating gap is provided between the partition and the mounting plate, through which air can flow back from the partition cavity to the first air inlet cavity.

[0009] Preferably, the ventilation assembly includes a first fan assembly and a second fan assembly, the first fan assembly and the second fan assembly being disposed through the mounting plate to connect the spacer cavity with the first air inlet cavity, the mounting plate is also provided with an air guide plate, the air guide plate surrounding the first fan assembly and the second fan assembly, and the first air inlet and the second air inlet being located within the area surrounded by the air guide plate.

[0010] Preferably, the first fan assembly and the second fan assembly are mounted on the fan housing, and the rear cover is mounted outside the first air inlet cavity.

[0011] Preferably, the first fan assembly and the second fan assembly rotate in opposite directions.

[0012] Preferably, the top cover is also provided with a skylight.

[0013] Preferably, the first fan assembly and the second fan assembly include a negative pressure fan and a wind turbine.

[0014] The beneficial effects of this invention are:

[0015] Air drawn in from the outside or inside the drying chamber is heated and then dispersed into the receiving cavity through two channels. Air from the first air inlet blows into the receiving cavity, while air from the second air inlet blows in from the bottom, increasing the airflow within the receiving cavity. The air within the receiving cavity flows in three directions within the partition cavity: one part disperses to the outside, ensuring pressure balance inside and outside the drying chamber and allowing fresh air from the outside to be drawn in; another part is drawn in through the ventilation components for internal circulation; and the third part flows into the first air inlet cavity through the gap between the mounting plate and the partition, also for internal circulation. This circulation method prevents the heated air from being directly exhausted to the outside, instead ensuring that most of it participates in the internal circulation of the drying chamber, reducing the amount of cold air drawn in from the outside, increasing the utilization rate of hot air, and reducing the energy consumption of the heating components. The two flow channels ensure smooth airflow within the drying chamber. Attached Figure Description

[0032] like Figures 1 to 9As shown, a circulating drying oven includes a shell, a ventilation assembly, and a heating assembly 3 disposed within the shell. The shell forms a receiving cavity 10 and a first air inlet cavity 40. The receiving cavity is a space for placing pets, and the first air inlet cavity is connected to the outside and provides outside air to the ventilation assembly. A partition cavity 30 is provided between the receiving cavity 10 and the first air inlet cavity 40. The partition cavity serves as a transition space; air from the receiving cavity flows into the partition cavity, some air is discharged outwards within the partition cavity, some air is drawn back into the first air inlet cavity by the ventilation assembly, and some air flows directly from the partition cavity into the first air inlet cavity. A second air inlet cavity 60 is provided at the bottom of the shell, and the second air inlet cavity 60 is connected to the receiving cavity 10. The ventilation assembly is disposed through a mounting plate 20, which has a first air inlet 25 and a second air inlet 26. The first air inlet 25 is connected to the receiving cavity 10, and the second air inlet 26 is connected to the second air inlet cavity 60. The accommodating cavity 10 and the partition cavity 30 are connected by an air outlet 271. The ventilation assembly and the heating assembly 3 are mounted on the mounting plate 20. The ventilation assembly connects the partition cavity 30 to the first air inlet cavity 40. The top of the housing is provided with a vent 121, which communicates with the partition cavity 30. The first air inlet cavity 40 is connected to the outside. The mounting plate has an inclined portion below it, and a second air inlet is located on the inclined portion. The inclined arrangement of the second air inlet facilitates airflow.

[0033] After the ventilation system is activated, air is drawn from the outside into the first air intake cavity 40 through the air inlet 141 of the rear cover 14. Simultaneously, some air is drawn into the receiving cavity 10. The drawn air is then ejected by the first air intake assembly 22 and the second air intake assembly 23, flowing inside the air guide plate. The air is then heated by the heating assembly 3. Part of the heated air flows directly into the receiving cavity 10 through the first air inlet 25, and the other part flows into the second air intake cavity 60 through the second air inlet 26, and then from the second air intake cavity 60 into the receiving cavity 10, thus drying the pet. The first air inlet 25 dries the area around the pet's body, while the air from the second air inlet 26 dries the pet's abdomen. The two air inlets increase the drying area and accelerate air circulation within the drying chamber.

[0034] like Figures 1 to 5 As shown, the outer casing includes a front cover 11, a top cover 12, a side cover 13, a rear cover 14, and a bottom cover 16, which are sequentially arranged to form a cuboid or cube-shaped shell. Figure 10As shown, a base plate 15 is provided between the bottom cover 16 and the top cover 12, and a receiving cavity 10 is formed above the base plate 15. A second air inlet cavity 60 is formed between the base plate 15 and the bottom cover 16. A mounting plate 20 is vertically provided on the bottom cover 16, and a partition 27 is provided on the mounting plate 20. A spacer cavity 30 is formed between the partition 27 and the mounting plate 20. The ventilation assembly includes a fan housing, and a first air inlet cavity 40 is formed between the mounting plate 20, the fan housing 21, and the rear cover 14. The partition 27 is fixedly installed on the mounting plate 20, and a first air inlet 25 is provided below the mounting plate 20, which directly connects the receiving cavity and the first air inlet cavity. A second air inlet 26 is provided below the first air inlet 25, which connects the first air inlet cavity and the second air inlet cavity. A ventilation hole connects the receiving cavity and the second air inlet cavity. A heating assembly 3 is provided in front of the first air inlet 25. The heating element heats the air drawn in by the ventilation element, and the heated air circulates through the first and second air inlets. The rear cover 14 is provided with an air inlet 141, which connects the outside environment to the first air intake cavity. Figure 7 As shown, the base plate 15 is provided with ventilation holes 151, and the partition plate 27 is provided with air outlet holes 271, which allow air in the receiving cavity 10 to flow into the partition cavity 30. The top plate 12 is provided with vent holes 121, which allow some air in the partition cavity to flow to the outside. The top cover 12 is also provided with a skylight 122, which allows the receiving cavity to circulate directly with the outside air by opening the skylight, thus improving the air environment in the receiving cavity when needed.

[0035] like Figure 9 As shown, the bottom plate 15 is inclined at the bottom of the outer casing. When the bottom plate is inclined, the air flowing into the second air inlet 26 flows upward from different positions on the bottom plate into the first air inlet cavity 10. Figure 10 and Figure 11 As shown, the base plate 15 includes air guide strips and ventilation holes 151, which are sequentially arranged on the base plate. The air guide strips have a downwardly convex arc-shaped structure. The air blown in by the second air inlet 26 is blocked by the air guide strips and blown upward into the accommodating cavity 10 through the ventilation holes.

[0036] The ventilation component is installed through the mounting plate 20, such as Figure 7 and Figure 9 As shown, the mounting plate is directly installed between the top cover and the bottom cover, and the partition is fixed by the mounting plate.

[0037] like Figure 9As shown, a communicating gap 50 is provided between the partition 27 and the mounting plate 20, allowing air to flow back from the partition cavity 30 to the first air inlet cavity 40 through the gap 50. The gap allows some of the air in the partition cavity to flow directly into the first air inlet cavity, increasing the amount of heated air participating in the circulation.

[0038] The ventilation assembly employs existing technology, including a first fan assembly 22, a second fan assembly 23, and an internally matched negative pressure fan and impeller. The first fan assembly 22 and the second fan assembly 23 are mounted on the fan housing 21. Upon startup, the ventilation assembly draws air from both ends of the fan and then ejects it radially along the impeller. The first fan assembly 22 and the second fan assembly 23 are connected through the mounting plate 20, allowing the spacer cavity 30 to communicate with the first air inlet cavity 40. The mounting plate 20 also has a guide plate 24, which surrounds the first fan assembly 22 and the second fan assembly 23. The first air inlet 25 and the second air inlet 26 are located within the area enclosed by the guide plate 24. The guide plate restricts the air intake from the first and second fan assemblies, ensuring directional airflow within the guide plate and creating a circulation loop within the drying chamber, preventing air from spreading.

[0039] The negative pressure fans in the first and second fan assemblies rotate in opposite directions, ensuring that the air drawn in by the two fans does not tilt in the same direction when it is ejected. This avoids uneven airflow within the drying chamber when the air enters the receiving cavity.

[0040] like Figure 4 As shown, the rear cover 14 is installed outside the first air inlet cavity 40. The first fan assembly 22 and the second fan assembly 23 have the same structure, but the internal fans rotate in opposite directions after installation. The two fan assemblies increase the air intake volume on the one hand, and the airflow volume inside the drying chamber on the other.

[0041] The drying oven in this invention features an internal circulation structure. The entire drying oven connects to the outside world through an air inlet on the rear cover and a vent on the top cover, serving as both intake and exhaust ports. During internal circulation, air flows into the receiving cavity through the first and second air inlets, and then into the partition cavity through the exhaust port. The air in the partition cavity flows in three directions: most air is directly drawn into the first air inlet cavity by the ventilation components, while a small portion flows to the outside and into the first air inlet cavity through gaps. Compared to the direct flow of air from the receiving cavity to the outside, this invention adds a partition cavity, distributing air within it. This increases the utilization rate of heated air, ensuring most air participates in the internal circulation. The added internal circulation also allows for the addition of a first and second air inlet to the air intake channel, and two fan assemblies are added, further facilitating smoother internal circulation. Both the fan assembly and the heating assembly are electrically controlled, employing existing technologies, which will not be described in detail here.

[0042] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the patent protection scope of the present invention should be defined by the claims.
