Abstract
Description
Technical Field
[0001] This application relates to the field of food preservation technology, and more specifically, to a pet food refrigerator. Background Technology
[0002] With the increasing popularity of pet ownership and growing awareness of pet health, pet food refrigeration equipment has become an important tool for modern family pet care. Current refrigeration equipment on the market utilizes thermoelectric refrigeration technology to achieve basic food preservation, and its design is optimized for different material housing structures. Refrigeration technology is developing towards refinement and functional integration to meet consumers' higher demands for safe pet food storage.
[0003] However, existing refrigeration equipment still has significant functional deficiencies. Its single refrigeration system cannot implement differentiated temperature control for wet and dry food with different moisture contents. This results in high-moisture wet food spoiling faster due to insufficient refrigeration, while low-moisture dry food suffers nutrient loss due to over-refrigeration. At the same time, conventional equipment lacks an active sterilization mechanism. When the door is opened, external pathogens can easily enter the storage cavity, creating a risk of microbial growth in the top area of the cavity that the refrigeration system cannot cover, directly affecting the hygiene and safety of pet food.
[0004] There is currently no effective technical solution to the above problems. Utility Model Content
[0005] The purpose of this application is to provide a pet food refrigerator that allows for the separate storage of wet and dry pet food, optimizes the storage effect, and prevents the growth of microorganisms.
[0006] This application provides a pet food refrigerator for storing pet food, including a box body. The box body has a wet food storage cavity and a dry food storage cavity arranged at the top and bottom. The box body is equipped with a first thermoelectric refrigeration component and a second thermoelectric refrigeration component for cooling the wet food storage cavity and the dry food storage cavity, respectively. The cooling capacity of the first thermoelectric refrigeration component is greater than that of the second thermoelectric refrigeration component. The top of the dry food storage cavity is equipped with a sterilization component that is activated when the door is closed.
[0007] The pet food refrigerator of this application has separate wet food storage chambers and dry food storage chambers with independent cooling and temperature control, so as to store pet wet food and pet dry food respectively. In addition, the pet food refrigerator of this application is also equipped with a sterilization component in the dry food storage chamber, which is activated when the door is closed.
[0008] The pet food refrigerator described herein, wherein the wet food storage chamber is cooled to a temperature of 2-8°C under the cooling action of the first thermoelectric refrigeration component, and the dry food storage chamber is cooled to a temperature of 14-22°C under the cooling action of the second thermoelectric refrigeration component.
[0009] The pet food refrigerator includes a second door hinged to the body for closing and sealing the dry food storage cavity. The body is also equipped with a sensing component for detecting whether the second door is closed. The sensing component is used to activate the sterilization component when the second door is detected to be closed.
[0010] The pet food refrigerator, wherein the sensing component includes a first reed switch disposed in the side of the box body near the hinge end of the second door and a magnetic component disposed in the side of the second door body near its hinge end, and the sterilization component is activated when the first reed switch is closed.
[0011] The pet food refrigerator mentioned above has multiple storage frames on the second door, and each storage frame has multiple detachable protective bars.
[0012] The pet food refrigerator includes two storage frames: one L-shaped and the other rectangular, with the rectangular frame abutting the inner corner of the L-shaped frame.
[0013] The pet food refrigerator mentioned above has a support plate at the bottom of the box body for supporting the second door after it is closed.
[0014] The pet food refrigerator is provided with a lighting unit that activates when the door is opened, wherein the wet food storage compartment and / or dry food storage compartment are equipped with a lighting unit that activates when the door is opened.
[0015] The pet food refrigerator described herein includes detachable brackets in both the wet food storage chamber and the dry food storage chamber.
[0016] The pet food refrigerator described herein, wherein the storage volume of the wet food storage chamber is smaller than the storage volume of the dry food storage chamber.
[0017] As can be seen from the above, the pet food refrigerator of this application has separate wet food storage chambers and dry food storage chambers with independent refrigeration and temperature control, so as to store pet wet food and pet dry food respectively. This allows the wet food storage chamber to be stored at a lower temperature to reduce the risk of spoilage, and the dry food storage chamber to be stored at a higher temperature to avoid nutrient loss. In addition, the pet food refrigerator of this application also has a sterilization component in the dry food storage chamber. The sterilization component is activated when the door is closed, which can effectively reduce microbial contamination and improve the hygiene and safety of pet food. Attached Figure Description

[0027] Please refer to Figures 1-3 Some embodiments of this application provide a pet food refrigerator for storing pet food, including a box body, with a wet food storage chamber 1 and a dry food storage chamber 2 arranged on the top and bottom of the box body. The box body is equipped with a first thermoelectric refrigeration component 3 and a second thermoelectric refrigeration component 4 for cooling the wet food storage chamber 1 and the dry food storage chamber 2, respectively. The cooling capacity of the first thermoelectric refrigeration component 3 is greater than the cooling capacity of the second thermoelectric refrigeration component 4. A sterilization component 5 is provided on the top of the dry food storage chamber 2, which is activated when the door is closed.
[0028] Specifically, the enclosure refers to the structure that houses the storage cavity, which can be made of plastic or metal materials and provides support and insulation in the design.
[0029] More specifically, wet food storage chamber 1 refers to a compartment for storing high-moisture pet food, which can be implemented using a partitioned space design. In this design, a target area is provided for the first thermoelectric refrigeration unit to achieve low-temperature preservation. Dry food storage chamber 2 refers to a compartment for storing low-moisture pet food, and in this design, a target area is provided for the second thermoelectric refrigeration unit to maintain a higher refrigeration temperature.
[0030] More specifically, the greater cooling capacity of the first thermoelectric refrigeration component 3 than that of the second thermoelectric refrigeration component 4 refers to the difference in cooling capacity, which can be achieved by using components with different power levels. In this scheme, the temperature of the wet grain chamber is ensured to be lower than that of the dry grain chamber.
[0031] More specifically, sterilization component 5 refers to a disinfection device, which can be implemented using an ultraviolet lamp. In the scheme, when the door is closed, the top of the dry food compartment is sterilized to eliminate microorganisms.
[0032] Specifically, the box includes a wet grain storage chamber 1 and a dry grain storage chamber 2 arranged vertically. A first thermoelectric cooling component 3 acts on the wet grain storage chamber 1, and a second thermoelectric cooling component 4 acts on the dry grain storage chamber 2. The difference in cooling capacity keeps the wet grain at a low temperature and the dry grain at a higher temperature. The sterilization component 5 is activated when the top door of the dry grain storage chamber 2 is closed to disinfect the area.
[0033] Compared with existing technologies, existing refrigeration equipment uses a single refrigeration system and cannot distinguish the temperature requirements of wet and dry grains; this application achieves targeted temperature control through independent refrigeration components and differences in refrigeration capacity; existing technologies do not have sterilization functions, and the closed-door sterilization component 5 of this application eliminates hygiene hazards at the top.
[0034] Through the above technical solution, the pet food refrigerator of this application distinguishes between wet food storage chamber 1 and dry food storage chamber 2 for independent refrigeration and temperature control, so as to store pet wet food and pet dry food respectively. This allows wet food storage chamber 1 to be stored at a lower temperature to reduce the risk of spoilage, and dry food storage chamber 2 to be stored at a higher temperature to avoid nutrient loss. In addition, the pet food refrigerator of this application is also equipped with a sterilization component 5 in dry food storage chamber 2. The sterilization component 5 is activated when the door is closed, which can effectively reduce microbial contamination and improve the hygiene and safety of pet food.
[0035] It should be noted that the first thermoelectric cooling component 3 and the second thermoelectric cooling component 4 have cooling and heat dissipation functions and are commonly used temperature regulation components for enclosed spaces. Their structure will not be described in detail here.
[0036] In some preferred embodiments, the cooling temperature of the wet grain storage chamber 1 under the cooling action of the first thermoelectric refrigeration component 3 is 2-8°C, and the cooling temperature of the dry grain storage chamber 2 under the cooling action of the second thermoelectric refrigeration component 4 is 14-22°C.
[0037] Specifically, the cooling temperature of 2-8℃ refers to the set temperature range of the wet food storage chamber 1, which can be achieved through temperature sensors and controllers, ensuring food preservation conditions in this scheme. The cooling temperature of 14-22℃ refers to the set temperature range of the dry food storage chamber 2, which can also be achieved through temperature sensors and controllers, ensuring the integrity of food nutrition in this scheme. This provides independent temperature-controlled environments for different food types, avoiding preservation problems caused by uniform refrigeration.
[0038] Compared to existing technologies, current refrigeration equipment uses a single refrigeration system, which cannot adapt to the different temperature control requirements of wet and dry food, leading to easy spoilage of wet food and nutrient loss of dry food. In contrast, this solution achieves targeted temperature management through independent temperature control in separate chambers, solving the problems of accelerated spoilage of wet food due to insufficient refrigeration and nutrient loss of dry food due to excessive refrigeration, thus ensuring the safe preservation and nutritional maintenance of pet food.
[0039] In some preferred embodiments, the box body is provided with a second door 21 hinged thereto for closing and sealing the dry food storage cavity 2. The box body is provided with a sensing component for sensing whether the second door 21 is closed. The sensing component is used to activate the sterilization component 5 when the second door 21 is sensed to be closed.
[0040] It should be noted that the box body is provided with a first door 11 that is hinged thereto for closing and sealing the wet grain storage chamber 1.
[0041] Specifically, the sensing component refers to the device used to detect whether the second door 21 is in the closed position, which can be implemented using optical sensors, mechanical switches, capacitive sensors, etc.
[0042] More specifically, the sterilization component 5 refers to a device for sterilizing the interior of the dry food storage chamber 2 with microorganisms, which includes an LED light source that emits ultraviolet light of a specific wavelength.
[0043] More specifically, the second door 21 on the cabinet is connected by a hinged structure, allowing for easy opening and closing, and sealing the dry food storage cavity 2 to form a relatively enclosed space. A sensing component is arranged on the cabinet and the second door 21 to monitor the status of the second door 21 in real time. When the second door 21 is closed and sealed, the sensing component detects this change and generates a corresponding signal. This signal is used to activate the sterilization component 5. The sterilization component 5, specifically a 254-270nm deep ultraviolet LED sterilization lamp, starts working after receiving the activation signal, emitting deep ultraviolet light to sterilize the inside of the sealed dry food storage cavity 2. This linkage control mechanism based on the door's closed state ensures that the sterilization process only occurs when the door is closed and the cavity is sealed, effectively preventing ultraviolet leakage and improving safety. Simultaneously, sterilization in a closed environment ensures that the ultraviolet light can fully penetrate the cavity, enhancing the sterilization effect. This solution, combined with the basic solution of setting up a dry food storage chamber 2 in a refrigerator and equipping it with a sterilization component 5, provides a reliable closed-door start-up mechanism, enabling the sterilization function to be implemented safely and effectively, thus solving the problem caused by the inaccurate sterilization start-up control in the prior art.
[0044] Through the above-described solution, this application can reliably sense the closed state of the second door 21 of the dry food storage cavity 2 and precisely control the activation of the sterilization component 5 based on this state. This avoids activating the sterilization component 5 when the door is open, preventing potential harm to the human body from ultraviolet rays and improving safety during use. Simultaneously, it ensures that the sterilization process takes place within the closed storage cavity, allowing ultraviolet rays to effectively act on the cavity interior, enhancing the sterilization effect and helping to maintain the hygiene and safety of the dry food.
[0045] In some preferred embodiments, the sensing component includes a first reed switch 10 disposed in the side of the housing near the hinge end of the second door 21 and a magnetic element (not shown) disposed in the side of the second door 21 near its hinge end. The sterilization component 5 is activated when the first reed switch 10 is closed or is activated after a delay after closing.
[0046] Specifically, the first reed switch 10 refers to an electrical switch that is closed or opened by the action of a magnetic field, and it can be implemented using a reed switch encapsulated in a glass tube. The magnetic component refers to an object that can generate a magnetic field, and it can be implemented using a permanent magnet.
[0047] More specifically, the start-up of the sterilization component 5 when the first reed switch 10 is closed or the delayed start-up after closing means that the timing of the power-on of the sterilization component 5 is controlled by the state of the first reed switch 10. It can be executed immediately when the switch detects the door closing signal, or it can be executed after a preset time interval based on the timer setting after the signal is detected.
[0048] More specifically, this solution constructs a door closing detection mechanism based on magnetic induction by setting a first reed switch 10 and a magnetic component on the cabinet and the second door 21, respectively. When the second door 21 is in the closed position, the magnetic component on the door approaches the first reed switch 10 on the cabinet, and the magnetic field generated by the magnetic component causes the first reed switch 10 to close, thereby outputting a door closing signal. This signal is used to control the activation of the sterilization component 5. The activation logic of the sterilization component 5 is set to activate immediately upon receiving the closing signal of the first reed switch 10, or to activate after a preset delay after receiving the signal. This design precisely links the detection of the door closing state with the activation of the sterilization function, ensuring that the sterilization function is executed only when the door is closed, avoiding accidental activation of the sterilization component 5 when the door is open, and improving safety. In addition, by introducing a delayed activation option, frequent triggering of sterilization due to brief door opening and closing can be avoided, improving the system's intelligence level and user convenience. This specific sensing method and flexible start-up timing control, combined with the overall functionality of the refrigerator, makes the storage environment for pet food more hygienic and reliable.
[0049] Through the above scheme, this application can accurately sense the closed state of the second door 21 and flexibly control the start-up timing of the sterilization component 5 according to the sensing result, thereby ensuring that the sterilization function is reliably executed after the door is closed, and improving the hygiene and safety of pet food storage.
[0050] In some preferred embodiments, the second door 21 is provided with a plurality of storage frames 211, and each storage frame 211 is provided with a plurality of detachable protective rods 212.
[0051] Specifically, the storage frame 211 refers to the structure installed inside or outside the second door 21 for carrying items. It can be made of plastic, metal, or composite materials, and can be formed into a frame structure with a certain volume or partitioning function through injection molding, welding, or bending. The frame can be fixed to the door or connected by means of buckles or sliding rails. The protective rod 212 can be connected to the storage frame 211 by plugging, snapping, or magnetic attraction, so that the protective rod 212 can be easily installed or removed as needed.
[0052] More specifically, this solution divides the available space on the second door 21 into different storage areas by setting multiple storage frames 211 on the second door body 21. This allows pet food, treats, feeding tools, or other related items to be placed in separate areas according to type or usage habits, improving space utilization efficiency and tidiness. Multiple removable protective bars 212 are installed on each storage frame 211. These bars form a physical barrier in front of the items, providing support, limiting, and fixing for the items placed within the storage frames 211. Even if the door shakes, the protective bars 212 effectively prevent items within the frames from tipping over, shifting, or falling due to inertia, ensuring the stability of the items. Simultaneously, the removable design of the protective bars 212 provides flexibility. Users can freely adjust the spacing and number of the protective bars 212 according to the size, shape, and quantity of the stored items, or selectively remove some of the protective bars 212 to facilitate access to larger or irregularly shaped items, or completely remove them when cleaning the storage frames 211, improving operational convenience.
[0053] Through the above solution, this application effectively utilizes the space on the second door 21 of the pet food cooler, providing a zoned and organized storage function, allowing pet food and related supplies to be neatly placed on the door. Simultaneously, by installing a detachable protective bar 212, it effectively prevents stored items from tipping over or falling due to shaking during door opening or closing, improving the stability and safety of item storage and greatly enhancing user convenience.
[0054] In some preferred embodiments, there are two storage frames 211, one of which is L-shaped and the other is rectangular, with the rectangular storage frame 211 abutting the inner corner of the L-shaped storage frame 211.
[0055] Specifically, the rectangular storage frame 211 is attached to the inner corner of the L-shaped storage frame 211 to form a semi-enclosed relationship. This layout provides additional lateral support and restraint for items placed in the frame, which can prevent items from tipping over or falling due to shaking during the opening or closing of the second door 21. This solves the problem of items being easily shaken or falling in the existing solution and reduces the risk of pet food storage.
[0056] Through the above solution, this application optimizes the utilization of the door's storage space, enhances the fixation of placed items, prevents items from shaking or falling when the door moves, and reduces the risk of damage or contamination of items.
[0057] In some preferred embodiments, the bottom of the box is provided with a support plate 6 for supporting the second door 21 after it is closed.
[0058] Specifically, the introduction of the support plate 6 is intended to provide an additional support point for the second door 21 in the closed state, thereby sharing the load generated by the weight of the door on the hinge and the connection between the door and the box.
[0059] The above solution effectively solves the structural stress problem caused by the weight of the door by adding a simple support structure to the bottom of the box, thereby improving the long-term reliability of the refrigerator and indirectly supporting the sealing and sterilization function of the dry food storage cavity 2. It also reduces the risk of hinge loosening, box deformation or door sagging during long-term use and helps to maintain the normal closed and sealed state of the second door 21.
[0060] In some preferred embodiments, the wet grain storage chamber 1 and / or the dry grain storage chamber 2 are provided with a lighting assembly 9 that activates when the door is opened.
[0061] Specifically, the lighting component 9 refers to a device for providing illumination, which can be implemented using light sources such as light-emitting diodes (LEDs), fluorescent lamps, or incandescent lamps. "Activation upon door opening" refers to a control method where the activation state of the lighting component 9 is linked to the opening state of the cabinet door. This can be achieved by setting up sensors that detect the cabinet door's state (such as mechanical switches, magnetic switches, or optical sensors) and corresponding control circuits, which will not be elaborated upon here.
[0062] More specifically, when the door of the wet food storage compartment 1 and / or dry food storage compartment 2 of the pet food refrigerator is opened, the sensor component detects the open state. This open signal is sent to the control circuit, which then drives the lighting component 9 to start. Once activated, the lighting component 9 provides illumination to the interior of the storage compartment, allowing the user to clearly see the pet food inside. When the door is closed, the sensor component detects the closed state, and upon receiving the close signal, the control circuit stops supplying power to the lighting component 9, turning it off. This mechanism ensures that the lighting component 9 operates only when needed, avoiding unnecessary energy consumption and heat generation. This solution, applied to pet food refrigerators with independent wet and dry food storage compartments 2, provides users with good visibility when accessing different types of pet food, improving the ease of use of the dedicated refrigeration equipment.
[0063] like Figure 3 As shown, in the dry food storage cavity 2, the lighting component 9 and the sterilization component 5 are integrated into an electronic circuit, and the two share a first reed switch 10 for activation. In this embodiment, the first reed switch 10 is preferably a single-pole double-throw (SPDT) reed switch.
[0064] In some preferred embodiments, both the wet grain storage chamber 1 and the dry grain storage chamber 2 are provided with removable brackets 7.
[0065] Specifically, the bracket 7 can be disassembled and installed using sliding fit, snap-fit connection, or simple placement support.
[0066] More specifically, by installing removable trays 7 in both the wet food storage compartment 1 and the dry food storage compartment 2, users can store different types or batches of pet food in two independent storage compartments. This layered storage method avoids food from being squeezed or mixed up, facilitating classification management and quick retrieval. The removable trays 7 give users the ability to flexibly adjust the internal space layout according to actual storage needs. They can be freely combined or removed according to the size and quantity of food packaging, thereby optimizing space utilization. At the same time, the removable design also greatly facilitates the cleaning of the refrigerator's interior. Users can easily remove the trays 7 for cleaning and thoroughly wipe the inside of the compartments, ensuring a hygienic storage environment and protecting the safety of pet food.
[0067] In some preferred embodiments, the bracket 7 has bent portions on both sides, and the two side walls of the wet grain storage cavity 1 and the dry grain storage cavity 2 are provided with sliding grooves 12, with a recessed limiting groove 13 in the middle of the sliding groove 12 for insertion and engagement with the bent portions.
[0068] Specifically, this solution addresses potential stability issues arising from the installation of a detachable bracket 7 within the storage cavity by optimizing the structure of the bracket 7 and the inner wall of the cavity. The bent portions on both sides of the bracket 7 are crucial for its integration with the structure on the inner wall of the cavity. The sliding grooves 12 on both sides of the wet grain storage cavity 1 and the dry grain storage cavity 2 provide a guiding path for the insertion and removal of the bracket 7, allowing it to slide smoothly within the cavity. Furthermore, a recessed limiting groove 13 is provided in the center of the sliding groove 12, specifically designed to engage with the bent portions on both sides of the bracket 7. This engagement ensures that when the bracket 7 is pushed into place, its bent portions engage with the limiting groove 13, thus positioning and limiting the bracket 7, preventing accidental slippage during use, and improving the stability of the bracket 7. Meanwhile, when it is necessary to remove the bracket 7, the user can use a certain operation (such as slightly lifting or tilting) to disengage the bent part from the limiting slot 13, and then smoothly remove the bracket 7 along the slide groove 12, ensuring the detachability of the bracket 7. Therefore, through the coordinated operation of the bent part of the bracket 7, the slide groove 12 on the side wall of the cavity, and the limiting slot 13 in the middle of the slide groove 12, a stable support and convenient operation of the detachable bracket 7 are achieved.
[0069] Through the above solution, this application solves the problem of the detachable bracket 7 easily slipping out or becoming unstable during use. The bracket 7 is engaged with the limiting slot 13 in the middle of the slide groove 12 via a bent portion, which provides stable support for the bracket 7 in its positioning position, effectively preventing accidental displacement or slippage due to shaking or contact, thus improving safety and convenience of use. At the same time, this structural design does not affect the normal installation and removal of the bracket 7, retaining its adjustable and easy-to-clean functions.
[0070] In some preferred embodiments, the storage volume of the wet grain storage chamber 1 is smaller than the storage volume of the dry grain storage chamber 2.
[0071] Specifically, under normal circumstances, the amount of dry pet food used is greater than that of wet pet food, and the temperature of wet food storage chamber 1 is lower than that of dry food storage chamber 2. Therefore, this application makes the storage volume of wet food storage chamber 1 smaller than that of dry food storage chamber 2 to fit the actual usage situation.
[0072] In some preferred embodiments, both the wet grain storage chamber 1 and the dry grain storage chamber 2 are provided with a drain plate 8 at the bottom.
[0073] Specifically, during the storage process, both dry and wet pet food may release moisture due to their own reasons or air. If moisture accumulates at the bottom of the dry and wet pet food for a long time, it will cause the dry and wet pet food to rot. Therefore, this application introduces a drain plate 8 to separate and drain the accumulated water, thereby optimizing the storage effect of dry and wet pet food.
