The drying box body is provided with a hot air outlet chamber, a guide chamber, and a pet holding chamber connected in sequence. The volute fan and the heating structure are both installed in the hot air outlet chamber, with the heating structure installed downstream of the volute fan.

[0002] Pet drying boxes allow the entire pet's fur drying process to be completed by machine, saving people the trouble of using water dryers or hair dryers to dry the pet's fur, thus saving labor costs.

[0003] Most pet drying boxes work by using a turbine fan to blow hot air into the pet's housing. Then, some of the hot air is expelled through the exhaust vents on the drying box, and the turbine fan continues to blow hot air into the pet's housing, creating a cycle to achieve the purpose of drying.

[0004] However, current pet drying boxes have the following problems: the airflow from the pet drying box into the pet's housing is not uniform enough, resulting in uneven drying speeds on different parts of the pet's body and poor drying effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a pet drying box air outlet structure and a pet drying box.

[0006] According to the present invention, a pet drying box air outlet structure includes a drying box body, a volute fan, and a heating structure; the drying box body is provided with a hot air outlet chamber, a guide chamber, and a pet holding chamber connected in sequence; the volute fan and the heating structure are both installed in the hot air outlet chamber, with the heating structure installed downstream of the volute fan; the hot air outlet chamber is the space between the back plate of the pet holding chamber and the back plate of the main body of the drying box body; a guide plate is provided in the guide chamber; after the volute fan generates air, the heating structure raises the temperature of the air to form hot air, which enters the guide chamber and, after being guided by the guide plate, flows to the pet holding chamber to dry the pet.

[0009] Preferably, the hot air outlet cavity is provided with a ventilation plate, which is located downstream of the heating structure; the air guide plate is installed at the end of the air guide cavity away from the ventilation plate; the air guide cavity and the hot air outlet cavity are connected through the ventilation plate.

[0042] Detailed Implementation

[0043] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the scope of protection of the present invention.

[0044] This invention provides a pet drying box air outlet structure, including a drying box body 400, a volute fan 610, and a heating structure; the drying box body 400 is provided with a hot air outlet cavity 623, an air guide cavity 630, and a pet receiving cavity 620 connected in sequence; the volute fan 610 and the heating structure are both installed in the hot air outlet cavity 623, and the heating structure is installed downstream of the volute fan 610;

[0045] The hot air outlet chamber 623 is the space between the back panel 621 of the pet-accommodating cavity and the main back panel 622 of the drying chamber body 400. A ventilation plate 624 is provided within the hot air outlet chamber 623. The ventilation plate 624 is located downstream of the heating structure and is integrally connected to the back panel 621. The ventilation plate 624 is inclined to the back panel 621. This inclined connection, compared to parallel or perpendicular connections, increases airflow variation, enhances turbulence, and increases wind speed. Ventilation holes are provided on the ventilation plate 624. These holes are either waist-shaped or elliptical. The irregular circular hole design further increases airflow velocity variation, enhances turbulence, and increases overall wind speed. The hot air outlet chamber 623 and the air guide chamber 630 are connected through these ventilation holes.

[0046] An air guide plate 631 is provided inside the air guide cavity 630; the air guide plate 631 is installed at the end of the air guide cavity 630 away from the air vent plate 624; the air guide cavity 630 and the hot air outlet cavity 623 are connected through the air vent plate 624; it is worth noting that the hot air outlet cavity 623 and the air guide cavity 630 are connected by a rounded corner 650, that is, when the hot air flows from the hot air outlet cavity 623 to the air guide cavity 630, the flow direction is changed by the rounded corner 650. The design of the rounded corner 650 can make the overall air outlet of the drying oven smoother and more uniform.

[0047] After the volute fan 610 generates air, the heating structure increases the temperature of the air to form hot air. The hot air enters the air guide cavity 630 through the air permeable plate 624 and flows to the pet receiving cavity 620 to dry the pet after being guided by the air guide plate 631.

[0048] The pet drying box's air outlet structure further includes an interconnected air outlet base plate 500 and an air outlet side plate 640; the air outlet side plate 640 is an arc-shaped plate. Both the air outlet base plate 500 and the air outlet side plate 640 are located between the pet receiving cavity 620 and the air guide cavity 630; in a preferred embodiment, there are two air outlet side plates, respectively distributed on both sides of the air outlet base plate 500. The air outlet base plate 500 is provided with a bottom air outlet 2, and the air outlet side plate 640 is provided with a side air outlet 641, the height of which is higher than the height of the air outlet base plate 500. The pet receiving cavity 620 and the air guide cavity 630 are connected via the bottom air outlet 2 and the side air outlet 641.

[0049] The air outlet base plate 500 includes a plate body 1, and the bottom air outlet 2 is disposed on the plate body 1. The bottom air outlet 2 includes a boss 21, a concave curved surface 22, and air outlet strips 23. The boss 21 protrudes from the plate body 1 and is arranged circumferentially along the concave curved surface 22. Multiple air outlet strips 23 are arranged along the arc of the concave curved surface 22. The multiple air outlet strips 23 are arranged parallel to each other, and the lengths of the multiple air outlet strips 23 are not exactly the same. The length direction of the side air outlet 641 is perpendicular to or inclined to the length direction of the air outlet strips 23 (see reference). Figure 8 The perpendicular design allows for a more even distribution of hot air blown from the air guide cavity 630 into the pet holding cavity 620.

[0050] The projection of the plate 1 on the ZOY plane includes a straight portion 11 and a raised portion 12 connected to each other; the area corresponding to the straight portion 11 is larger than the area corresponding to the raised portion 12, and the length and / or width of the air outlet strip 23 on the straight portion 11 is larger than the length and / or width of the air outlet strip 23 on the raised portion 12. The design of the size of the raised portion 12 and the air outlet strip on the raised portion 12 helps to ensure uniform airflow from the entire air outlet base plate 500.

[0051] In a preferred embodiment, the heating structure is an electric heater 700. The temperature of the hot air is 35-40 degrees Celsius.

[0052] The present invention also provides a pet drying box, such as Figure 1-19As shown, the pet drying box includes an air outlet structure. The volute fan 610 has an internal air intake, an external air intake, and a fan outlet; the internal air intake is connected to the pet housing cavity 620, the external air intake is connected to the external environment, and the fan outlet is connected to the hot air outlet cavity 623. In a preferred embodiment, both the internal air intake and the external air intake are equipped with filter screens to filter pet hair in the pet housing cavity 620 and particulate impurities in the external environment, respectively.

[0053] The pet drying box is also equipped with an exhaust structure, and the pet housing 620 is connected to the external environment through the exhaust structure.

[0054] In the hot air outlet chamber 623, after the volute fan 610 generates air, the temperature of the air is increased by the heating structure to form hot air. The hot air passes through the air guide chamber 630 and the pet holding chamber 620 in sequence to dry the pet. A portion of the hot air is discharged to the outside through the exhaust structure; another portion of the hot air is drawn away by the volute fan 610 and, together with the freshly drawn ambient air from the outside, forms hot air again in the hot air outlet chamber 623, thus realizing the recycling of hot air. In a preferred embodiment, the total exhaust area (air discharged to the outside), the total return air area (hot air drawn by the volute fan 610), and the total outlet air area (air blown from the air guide chamber 630 to the pet holding chamber 620) of the pet drying box increase sequentially. This design ensures that a small portion of the hot air is discharged to the outside through the exhaust structure, while most of the hot air is drawn away by the volute fan 610, achieving the technical effect of recovering as much heat energy as possible and minimizing hot air waste.

[0055] The exhaust structure includes a first exhaust surface 100, a second exhaust surface 110, and a third exhaust surface 120. The first exhaust surface 100 is located on the left side of the pet drying box, and a plurality of first exhaust holes 130 are provided on the first exhaust surface 100. The second exhaust surface 110 is located on the right side of the pet drying box, and a plurality of first exhaust holes 130 are provided on the second exhaust surface 110. The first exhaust holes 130 on the first exhaust surface 100 and the first exhaust holes 130 on the second exhaust surface 110 are arranged symmetrically. The third exhaust surface 120 is located on the front door of the pet drying box, and a plurality of second exhaust holes 140 are provided on the third exhaust surface 120. The plurality of second exhaust holes 140 are evenly distributed in the lower part of the front door of the pet drying box. Both the first exhaust holes 130 and the second exhaust holes 140 are used to connect the pet-containing cavity of the drying box to the outside.

[0056] In one preferred embodiment, the dimensions of the multiple first exhaust vents 130 are not entirely identical. In one preferred embodiment, the first exhaust vent 130 is a circular vent, and the diameter of the first exhaust vent 130 decreases progressively from the center of the exhaust surface to the periphery of the exhaust surface. The second exhaust vent 140 is an oblong or elliptical vent. In another preferred embodiment, the first exhaust vent 130 is an oblong vent, and the length of the first exhaust vent 130 decreases progressively from the center of the exhaust surface to the periphery of the exhaust surface. The height of both the first exhaust vent 130 and the second exhaust vent 140 is higher than the height of the exhaust base plate 500. This design helps to create turbulence in the pet housing cavity 620, making the exhaust and exhaust of the pet drying box more rapid.

[0057] The air outlet base plate 500 also includes a support leg structure 200, which is disposed below the plate body 1. The support leg structure 200 supports the plate body 1, forming an air guide cavity 630 between the bottom plate 430 of the drying chamber body 400 and the air outlet base plate 500. Specifically, one end of the support leg structure 200 is connected to the plate body 1, and the other end is supported on the bottom plate 430. In addition, the design of the support leg structure 200 increases the hot air turbulence in the air guide cavity 630, making the air outlet from the air outlet base plate 500 to the pet housing cavity 620 more rapid. In a preferred embodiment, the top diameter of the support leg structure 200 is smaller than the bottom diameter, and the top and bottom surfaces of the support leg structure 200 are smoothly connected. This design, utilizing the shape of the air guide column itself, provides a certain guiding effect for the hot air.

[0058] The air guide plate 631 is inclinedly disposed at one end of the air guide cavity 630; the angle θ between the air guide plate 631 and the horizontal plane is 30°-60°, preferably 45°. Figure 13 and Figure 16 As shown, the air guide plate 631 has a structure that is wide in the middle and narrow on both sides (i.e., as shown in the figure). Figure 16 As shown, the width 'a' of the middle section of the air guide plate 631 is greater than the width 'b' of the side section. This design allows more hot air to enter the pet receiving cavity from the bottom air outlet plate 500 of the pet drying system, rather than more from the side air outlet plate. This allows the pet's abdomen to dry faster and prevents it from getting cold. Furthermore, the number of bottom air outlets 2 on the bottom air outlet plate 500 is greater than the number of side air outlets 641, allowing more hot air to enter the pet receiving cavity and achieving a more efficient distribution of hot air. Preferably, as... Figure 13 As shown, the middle part of the air guide plate 631 is connected to both sides by an arc-shaped portion 632. Figures 13-14As shown, the top end of the air guide plate 631 is located at the end of the air guide cavity 630 near the front door of the pet drying box; the bottom end of the air guide plate 631 is located in the area corresponding to the bottom air outlet 2 closest to the front door of the pet drying box within the air guide cavity 630. The air guide plate 631 is a plastic air guide plate. Plastic air guide plates have the advantages of being lightweight, having good physical and chemical properties, and being easy to process and mold. In a preferred embodiment, the ventilation plate 624 is arranged parallel to the air guide plate 631.

[0059] The pet drying box also includes the plug 420; a bottom drain outlet 440 is provided on the bottom plate 430 of the drying box body 400, and the bottom drain outlet 440 is connected to the outside of the pet drying box; the plug 420 is detachably plugged on the bottom drain outlet 440. Specifically, the plug 420 is provided with a connecting part 422; the connecting part 422 is located at the end of the plug 420; the bottom plate 430 is provided with a hole structure, and the plug 420 is installed on the bottom plate 430 through the matching of the connecting part 422 and the hole structure 450. It is worth noting that the bottom air outlet 2 also functions as a drain outlet, the air outlet strip 23 also functions as a drain strip, and the air guide cavity 630 also functions as a water accumulation space, and the bottom of the air guide cavity 630 is the bottom plate 430 of the drying box body 400. In a preferred embodiment, the center point of the plate 1 is the lowest point, and the air outlet strip 23 is provided at the lowest point. If the pet is not wiped with a towel before entering the drying box and has a lot of water droplets, the flow and discharge path of the water droplets in the pet drying box is as follows: hot air blows the water droplets off the pet to the bottom air outlet 2, and the water droplets flow from the air outlet strip 23 into the air guide cavity 630; after a single drying cycle, the operator can open the plug 420 to discharge the water droplets in the air guide cavity 630. In a preferred embodiment, the projection of the bottom plate 430 of the drying box body 400 on the ZOX plane is a U-shaped structure, and the bottom water outlet 440 is located at the lowest point of the U-shape of the bottom plate 430. The bottom water outlet 440 is located downstream of the air guide cavity 630, that is, the distance between the bottom water outlet 440 and the front door of the pet drying box is less than the distance between the bottom water outlet 440 and the ventilation plate 624. This design allows the water droplets to reach the bottom water outlet 440 more quickly with the help of gravity and the thrust of the hot air.

[0060] In a preferred embodiment, the rotational speed of the volute fan increases linearly or non-linearly, such as by gradually increasing the rotational speed of the volute fan. This allows the cat to adapt gradually, preventing it from suddenly experiencing strong winds and noise, thus preventing stress. Specifically, the full-load rotational speed of the volute fan is 1600 rpm. The fan speed initially operates at 10% of the full load, then at 30% for 1 minute, then at 40% for 2 minutes, then at 50% for 2 minutes, then at 60% for 3 minutes, then at 70% for 4 minutes, and finally at 80% of the full load.

[0061] In a preferred example, such as Figure 7 As shown, the hot air outlet cavity 623 is also equipped with a main control module, a temperature and humidity sensor 800, and a temperature sensor. The temperature and humidity sensor 800 measures the outlet temperature and humidity data of the volute fan 610, and the temperature sensor measures the duct temperature data next to the heater 700. The main control module adjusts the heater 700 according to the outlet temperature data and the duct temperature data, and adjusts the volute fan 610 according to the outlet humidity data.

[0062] The temperature sensors include a first temperature sensor 910 and a second temperature sensor 920. The first temperature sensor 910 and the second temperature sensor 920 are respectively disposed on both sides of the bottom of the heater 700 along the air duct direction. The dual sensors monitor the temperature of the heater 700 in real time, and this dual detection enhances the safety protection level. The main control module is electrically connected to the first temperature sensor 910 and the second temperature sensor 920. When the main control module simultaneously acquires temperature data from both sensors, and the difference between the two temperature data is less than a threshold, the average temperature of the first temperature sensor 910 and the second temperature sensor 920 is taken as the air duct temperature data. In a preferred embodiment, the first temperature sensor 910 and the second temperature sensor 920 are NTC temperature sensors, and the heater 700 is a PTC heater 700.

[0063] The main control module obtains the inlet air temperature based on the vent temperature data and the duct temperature data. It then calculates the actual temperature inside the pet-accommodating cavity 620. If the actual temperature is higher than the preset value, the heater 700 stops heating; if the actual temperature is lower than the preset value, the heater 700 continues heating. The main control module dynamically adjusts the speed of the volute fan 610 based on the outlet humidity data, and the speed of the volute fan 610 decreases as the outlet humidity decreases.

[0064] In a preferred embodiment, the actual temperature of the pet-receiving cavity 620 inside the drying oven is calculated as follows:

[0065] Step S1: Obtain the air outlet temperature data and the air duct temperature data, and set the heat transfer coefficient n between the air outlet and the air duct. The heat transfer coefficient n is determined according to the actual design and is related to factors such as the design location, shape, material, and fluid dynamics of the air duct.

[0066] Step S2: Set the temperature correction factor m to correct the influence of the duct temperature on the inlet air temperature. Then: Corrected duct temperature = duct temperature × temperature correction factor m.

[0067] Step S3: Calculate the inlet air temperature based on the difference between the corrected duct temperature and the air outlet temperature, and the heat transfer coefficient n. Then: Inlet air temperature = Air outlet temperature + (Corrected duct temperature - Duct temperature) + Air outlet temperature × Heat transfer coefficient n.

[0068] Step S4: Based on the heating effect of heater 700 and the natural convection heat transfer power Q conv Natural radiative heat transfer power Q rad And the circulation effect, calculate the actual temperature inside the drying oven, where:

[0069] Heating effect = heating power P × heater 700 operating state coefficient k; where the heater 700 operating state coefficient k is related to the duty cycle of the PWM waveform controlled by the heater 700, for example, 0.9.

[0070] Natural convection heat transfer efficiency: Q conv =h×A×(T) surface -T ∞ h represents the natural convection heat transfer coefficient, typically ranging from 10 to 100 W / (m²·K). A represents the internal surface area of ​​the drying oven, and T... surface T represents the average temperature of the inner surface of the drying oven. ∞ Indicates ambient temperature;

[0071] Natural radiative heat transfer power: Q rad =ε×σ×A×(T) surface 4 -T ∞ 4 );

[0072] Circulation effect = F × (inlet air temperature - T0), where F is the circulation effect factor, with a value between 0 and 1; T0 represents the preset control temperature;

[0073] Actual temperature inside the drying oven = inlet air temperature + heating effect - Q cobv -Q rad + Loop effect.

[0074] Step S5: Update the average temperature inside the drying oven in real time until the actual temperature inside the drying oven stabilizes. Update the average temperature T of the inner surface of the pet holding cavity 620.surface = (Inlet air temperature + Actual temperature) / 2. Repeatedly update the average temperature inside the drying oven to guide the actual temperature inside the drying oven to stabilize. That is, stop the iterative calculation when the difference between the actual temperature and the previously calculated actual temperature is less than the set threshold.

[0075] This algorithm fully considers the impact of duct temperature on inlet air temperature, and takes into account the effects of heater 700, natural heat dissipation, and circulating fan on the temperature inside the pet housing 620. It also considers the heat transfer effect between the duct and the air outlet, including the heat transfer coefficient and temperature correction coefficient. The above calculation factors can be adjusted according to actual design conditions and control logic to more accurately measure and control the temperature.

[0076] The pet drying box provided by this invention achieves fully automatic control of the drying process based on temperature and humidity data. Specifically, refer to... Figure 19 As shown, the control system divides the entire drying process into multiple drying stages. The main control module dynamically adjusts the power of the volute fan 610 and the heater 700 according to the drying stage. The drying stages include the preheating stage, the quick-drying stage, and the hair care stage in sequence.

[0077] During the preheating phase, the rotation speed of the volute fan 610 gradually increases until it reaches a preset maximum value. This allows the pet to gradually adapt to the dryer and prevents it from being startled. The heater 700 operates at a preset maximum power value. On the one hand, in the initial stage, because there is a lot of moisture on the pet's fur, operating the heater 700 at maximum power can accelerate the evaporation of moisture and prevent the pet from getting cold. On the other hand, the moisture on the fur can also protect the pet, allowing for higher temperatures to be used for drying without burning the pet, thus improving drying efficiency. The preheating time is set based on the initial humidity data at the air outlet. The higher the initial humidity data at the air outlet, the more moisture is on the pet's fur, and the longer the preheating time is required.

[0078] During the quick-drying phase, the volute fan 610 and heater 700 operate at their preset maximum power values ​​to rapidly dry the moisture on the pet's fur. Specifically, the duration of the quick-drying phase is set according to the pet's size; the larger the pet, the longer the quick-drying time. The main control unit determines the pet's size based on the time it takes for the unit humidity data to change during the preheating phase; the longer the time it takes for the unit humidity data to change, the larger the pet is considered to be, and the longer the duration of the quick-drying phase should be.

[0079] During the hair care stage, the heater 700 stops working, and the rotation speed of the volute fan 610 gradually decreases, using the residual heat of the air to dry the pet's fur, thus avoiding damage to the fur from hot, dry air. During the quick-drying stage, the hair care stage begins when the humidity at the air outlet drops to the set value.

[0080] The pet drying box provided by this invention determines the drying progress of the pet by measuring temperature and humidity data, thereby controlling the drying time and temperature. Compared with the timed drying methods used in existing technologies, this drying box does not require manual setting of drying parameters and avoids situations where the pet's fur is not completely dried or over-dried, significantly improving the drying effect. This invention achieves accurate measurement of the temperature within the drying box's cavity by using temperature and humidity sensors and a temperature sensor installed in the air duct, combined with a temperature compensation algorithm. Furthermore, it eliminates the need to place the sensors inside the drying box cavity, thus preventing damage to the sensors by the pet and affecting the drying effect. This invention sets parameters for each drying stage solely based on data from the temperature and humidity sensors and the temperature sensor, greatly reducing the hardware cost of the drying box while allowing for different drying parameters to be set for different pets.

[0081] In a preferred embodiment, the air outlet base plate 500 is a detachable base plate, and the air outlet base plate 500 further includes a first detachable connector. The plate body 1 is detachably installed at the bottom of the pet holding cavity of the pet drying box via the first detachable connector; in a preferred embodiment, such as Figure 12 As shown, the first detachable connector is a snap-fit ​​structure. The snap-fit ​​structure is disposed at the end of the straight portion 11. The snap-fit ​​structure includes a first positioning post 300 and a head 310. The head 310 is mounted on the first positioning post 300. Preferably, the head 310 and the first positioning post 300 are integrally connected.

[0082] The pet drying box has a base plate 430 integrally connected to a second positioning post 320; the second positioning post 320 has a groove 330; the groove 330 can match the head 310. The first positioning post 300 and / or the second positioning post 320 are positioning posts with elastic deformation capability. The first positioning post 300 and / or the second positioning post 320 are plastic first positioning posts.

[0083] In another preferred embodiment, the first detachable connector is not a snap-fit ​​structure, but a first magnetic structure. The pet drying box is also provided with a second magnetic structure, and the first and second magnetic structures are magnetically attracted to each other.

[0084] In a preferred embodiment, the pet drying box also includes an electronic lock. The electronic lock is installed on the front door of the pet drying box and is electrically connected to a temperature sensor. When the user opens the pet drying box, the electronic lock automatically locks. The electronic lock only unlocks after the temperature sensor detects that the temperature inside the pet holding cavity 620 has reached a set value, such as 35 degrees Celsius, allowing the user to put in the pet. This design allows the pet holding cavity 620 to create a warm environment before the pet is placed inside, improving the overall efficiency of pet drying.

[0085] In a preferred embodiment, the pet drying box further includes an overall lighting system comprising multiple LEDs disposed at the top of the pet receiving cavity 620. The pet drying box also includes an ozone generator and a negative ion generator, both installed in the hot air outlet cavity 623 and located downstream of the volute fan 610.

[0086] In a preferred embodiment, the pet drying box is also equipped with a display control screen on the top, which allows users to view information such as the internal temperature of the drying box and the remaining drying time, as well as to open and close the door and set the temperature.

[0087] The hot air from the pet drying box passes sequentially through the hot air outlet cavity 623, the air guide cavity 630, and the pet receiving cavity 620, forming a complete air outlet path. Combined with the air guiding effect of the air guide plate 631, the raised shape of the air outlet base plate 500, and the concave design of the air outlet, the pet drying box achieves uniform airflow. Furthermore, the air outlet of this invention features a raised platform design, ensuring that the pet will first contact the platform when lying down. The design of the air outlet strips arranged on the concave curved surface ensures that the pet's belly fur maintains a certain distance from the air outlet strips when lying down, reducing the possibility of the pet's belly fur directly blocking the air outlet strips and improving the airflow efficiency of the bottom air outlet plate.

[0088] The pet drying box achieves uniform airflow and improves airflow efficiency by symmetrically arranging the first exhaust hole 130 on the first exhaust surface 100 and the first exhaust hole 130 on the second exhaust surface 110, and setting the second exhaust hole 140 on the front door of the pet drying box, with multiple second exhaust holes 140 evenly arranged.

[0089] The pet drying box combines the air guide cavity 630 with the water accumulation space, and the bottom air outlet 2 with the drain outlet, so that one structure has two functions at the same time. The pet drying box can perform the air outlet function and the drain function at the same time.
