Description

Technical Field

[0001] This utility model relates to the field of food thawing technology, specifically a food thawing device. Background Technology

[0002] It is common practice in households to wrap food in a food storage container or bag and freeze it in the freezer for later use. However, frozen food cannot be eaten immediately. It needs to be thawed first, and then processed and cooked before it can be consumed.

[0003] Generally speaking, there are several ways to defrost food. First, leave the food in the air to thaw naturally, which takes a relatively long time and poses certain safety risks from a food safety perspective. Second, move the food from the freezer to the crisper drawer and thaw it slowly, also a relatively long process. This method preserves the flavor of the food well and is considered a better defrosting method. Third, soak the food in water, whether cold or hot, with similar effects and a shorter defrosting time, but the direct contact with water can somewhat damage the flavor. Fourth, defrost the food in a microwave, which may seem to achieve the desired effect in minutes, but uneven heating can occur, resulting in the outside thawing while the internal ice remains, potentially affecting the food's quality. In short, different defrosting methods result in vastly different defrosting times, directly impacting food quality. Therefore, reducing defrosting time while ensuring food quality is a pressing issue that needs to be addressed.

[0004] The sink is the heart of the kitchen. Cooking rice, washing vegetables, cooking, and cleaning after meals all depend on the sink. Besides water and water drainage, the sink currently doesn't have many other functions. Utility Model Content

[0005] The purpose of this invention is to provide a water tank that combines food defrosting function to address the shortcomings of existing technology. By pressurizing and ventilating the defrosting box and immersing it in the water tank, the cold energy of the frozen food is removed through airflow, and the water used to immerse the defrosting box also removes some of the cold energy. This two-pronged approach, circulating continuously, achieves rapid defrosting without affecting the quality of the food, thus solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A food defrosting device includes a water tank body and a defrosting box located inside the water tank body. The defrosting box has an air inlet and an air outlet. The air inlet is connected to an air pump located outside the water tank body through an air supply pipe. The water tank body has a water inlet and a water outlet.

[0008] Furthermore, the air pump is fixedly installed on the outside of the water tank body, and an air supply connection port is provided on the water tank body. The air supply pipe includes a first air pipe and a second air pipe. One end of the first air pipe is connected to the air pump, and the other end is connected to the air supply connection port on the outside of the water tank body. One end of the second air pipe is detachably connected to the air supply connection port on the inside of the water tank body, and the other end is detachably connected to the air inlet of the defrosting box.

[0009] Furthermore, the air inlet is located on one side of the defrosting box, and the air outlet is located on the other side of the defrosting box. The defrosting box includes a box body and a box cover that are interlocked and sealed together. The air inlet is located on the box body, and the air outlet is located on the box cover. The horizontal straight-line distance between the air inlet and the air outlet is the greatest.

[0010] Furthermore, there are multiple air outlets, which are arranged in a fan-shaped array on the box body. The air outlets closer to the air inlet have a smaller diameter, while the air outlets farther from the air inlet have a larger diameter.

[0011] Furthermore, the defrosting box has a square structure, with three chamfered corners and one rounded corner at the horizontal corners of the box body. The lid has a corresponding structure design, with the air outlet located at the rounded corner of the lid and the air inlet located at the chamfered corner of the box body that is diagonally opposite to the rounded corner.

[0012] Furthermore, it also includes a controller, wherein the water inlet is equipped with an electric two-way valve, the drain outlet is equipped with an electric two-way valve, and the controller is electrically connected to the electric two-way valve, the electric two-way valve, and the air pump.

[0013] Furthermore, the defrosting box is equipped with a counterweight or a suction cup.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention connects the defrosting box to the air pump via an air supply pipe, enabling continuous air exchange within the defrosting box. It also achieves circulating water filling and drainage within the water tank via a water inlet and outlet. These two methods of cold exchange complement each other, quickly removing the cold energy from the frozen food inside the defrosting box. This achieves rapid defrosting of food without affecting its quality, and is convenient to operate and cost-effective.

[0016] By utilizing the sink as an essential kitchen appliance, and taking into account the liquid water that will inevitably be produced during the food thawing process (frost melting into water), the sink can be used to wash and process food directly after thawing. This clever combination of features makes full use of the sink's advantages.

[0017] Compared to conventional thawing methods, this invention offers shorter thawing time, higher thawing rate, and is safer and more hygienic, while preserving the quality of the food to the greatest extent possible, thus facilitating people's daily lives. Attached Figure Description

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0025] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0026] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0028] For easier understanding, please refer to Figure 1 and Figure 4 This embodiment provides a food defrosting device, including a water tank body 1 and a defrosting box 2. The water tank body 1 has a drain pipe outlet, a water inlet 11, and a drain outlet 12. The water inlet 11 is connected to an indoor tap water pipe to fill the water tank body 1 with water, and the drain outlet 12 is connected to the water drain pipe to drain the water from the water tank body 1. In the initial state (when the defrosting function is not needed), the water inlet 11 and the drain outlet 12 are normally closed, which does not affect the normal use of the water tank body. The defrosting box 2 has an air inlet 211 and an air outlet 221. One end of the air supply pipe 3 is connected to the air inlet 211 of the defrosting box 2 located inside the water tank body 1, and the other end of the air supply pipe 3 is connected to an air pump 4 located outside the water tank body 1. The air pump 4 delivers positive pressure air into the defrosting box 2 through the air supply pipe 3. Preferably, the air supply pipe 3 is made of a soft material. The defrosting container 2 has a counterweight (not shown in the figure) at its bottom. This counterweight increases the overall weight of the defrosting container, ensuring that it remains in contact with the bottom wall of the sink body 1 and does not float due to buoyancy. Furthermore, the counterweight is detachably attached to the bottom wall of the defrosting container 2. Users can selectively install it based on the weight of the food to be defrosted. If the food is light, the counterweight can be installed on the bottom wall of the defrosting container 2 to ensure it is submerged in water. Alternatively, a silicone suction cup can be used instead of the counterweight to attach it to the bottom of the sink body. If the food is heavy and its weight exceeds buoyancy, the defrosting container 2 can be submerged without the counterweight.

[0029] Place the food to be thawed into the defrosting box 2, and place the defrosting box 2 inside the water tank body 1. Seal the drain pipe opening of the water tank with the water tank sealing cap. Connect the defrosting box 2 to the air pump 4 through the air supply pipe 3. Start the air pump 4, and simultaneously fill the water tank body 1 with water through the water inlet 11 until the water level is above the defrosting box 2. The air pump 4 continuously supplies positive pressure air into the defrosting box 2. The cold air inside the defrosting box 2 is compressed by the positive pressure air and continuously discharged from the air outlet 221 of the defrosting box 2 into the water in the water tank body 1, forming bubbles. After the bubbles rise to the water surface, they burst and evaporate, thus achieving air flow and exchange inside the defrosting box 2. The food inside the defrosting box 2 loses its cold energy. After a certain time interval, the water in the water tank 1, having soaked the defrosting box 2, absorbs some of the cold energy transferred from the defrosting box 2 through thermal radiation and air exchange, resulting in a lower water temperature than when it was first soaked. At this point, the drain outlet 12 is opened to drain the water out of the water tank 1 after the cold energy exchange is complete. After draining, water is refilled into the water tank 1 through the water inlet 11 until the water level is higher than the defrosting box 2. During the draining and refilling process, the air pump 4 continuously delivers positive pressure air into the defrosting box 2. This cycle continues until the food is defrosted. Because air is continuously squeezed out from the air outlet 221 of the defrosting box 2, water in the water tank 1 will not enter the interior of the defrosting box 2 from the air outlet 221, thus achieving water-resistant defrosting.

[0030] For better understanding, please continue reading. Figure 1 and Figure 4 The air pump 4 is fixedly installed on the outer wall of the water tank body 1, and the water tank body 1 has an air supply connection port 13 on the same side wall. The air supply pipe 3 includes a first air pipe 31 and a second air pipe 32. One end of the first air pipe 31 is fixedly connected to the air pump 4, and the other end is fixedly connected to the outer end of the air supply connection port 13 on the outer side of the water tank body 1. One end of the second air pipe 32 is detachably connected to the inner end of the air supply connection port 13 on the inner side of the water tank body 1, and the other end is detachably connected to the air inlet 211 of the defrosting box 2. During construction and installation, the outer end of the air supply port 13 on the sink body 1 is connected to the air pump 4 via the first air pipe 31. The first air pipe 31 and the air pump 4 are designed to be hidden. When the user needs to use the defrosting function, he / she only needs to connect the two ends of the second air pipe 32 to the inner end of the air supply port 13 and the air inlet 211 of the defrosting box 2, respectively. The air pump 4 can be turned on by the controller to exchange air flow inside the defrosting box 2. When the user does not need to defrost food, the second air pipe 32 can be removed from the air supply port 13, and the defrosting box 2 and the second air pipe 32 can be separated, cleaned and stored without occupying the internal space of the sink body 1. At the same time, the defrosting box 2 and the second air pipe 32 are kept clean and hygienic, and can be used immediately.

[0031] For better understanding, please continue reading. Figure 1 and Figure 4 The defrosting box 2 includes a lower box body 21 and an upper lid 22, which are connected by a snap-fit ​​seal. Preferably, the lid 22 has a sealing strip at the snap-fit ​​connection with the box body 21 to ensure that there is no water leakage at the connection after the lid 22 and the box body 21 are snapped together. The defrosting box 2 has a square structure. Both the box body 21 and the lid 22 have three chamfered corners and one rounded corner at the four corners in the horizontal direction. Multiple air outlets 221 are arranged vertically in a fan-shaped array near the rounded corners of the lid 22. Air inlets 211 are horizontally located at the chamfer on the side of the box body 21 opposite to the rounded corner (diagonally opposite), so that the horizontal straight-line distance between the air inlet 211 and the air outlet 221 is as far as possible, while the air outlet is close to the air inlet 211. The outer ring air outlet 221 (far from the rounded corner) has a smaller diameter, while the inner ring air outlet 221 (far from the air inlet 211 and close to the rounded corner) has a larger diameter. This ensures that the air delivered to the defrosting box 2 via the air supply pipe 3 can traverse the entire internal space of the defrosting box 2 as much as possible before being discharged. This allows the airflow path inside the defrosting box 2 to cover the entire internal space of the defrosting box 2, thus enabling the exchange of cold air throughout the defrosting box 2 and improving the defrosting rate. The three-chamfered-one-rounded-corner structural design achieves a foolproof design without occupying the internal space of the defrosting box 2 and with convenient operation. It prevents users from fastening the air outlet 221 directly above the air inlet 211 when fastening the box body 21 and the lid 22. This would result in a short delivery path for the positive pressure air delivered through the air pipe 3 inside the defrosting box 2, making it impossible to exchange cold air throughout the defrosting box 2. The overall structure of the defrosting box 2 is simple, the manufacturing cost is low, and it is easy to fasten and disassemble.

[0032] The sink body 1 also integrates a controller. A water inlet electric two-way valve is located at the water inlet 11, and a drain electric two-way valve is located at the drain outlet 12. The controller is electrically connected to the water inlet electric two-way valve, the drain electric two-way valve, and the air pump 4. Initially, both the water inlet and drain electric two-way valves are in the off state. When using the defrost function, the food to be defrosted is placed in the defrost box 2. After connecting the defrost box 2 and the air supply port 13 via the second air pipe 32, the user presets the water volume and soaking time on the controller to activate the defrost function. The controller then activates the air pump 4 and simultaneously controls the water inlet electric two-way valve to open for water injection. Once the preset water volume is reached, the water inlet electric two-way valve closes to stop water injection. A timer then starts the soaking process, and after the time is up, the drain electric two-way valve opens to drain water. This cycle repeats until the draining is complete, achieving automated defrosting.

[0033] Although the present invention has been described using the above preferred embodiments, it is not intended to limit the scope of protection of the present invention. Any changes and modifications made by those skilled in the art to the above embodiments without departing from the spirit and scope of the present invention shall still fall within the scope of protection of the present invention.
