Description

Technical Field

[0001] This application relates to a cooling device, specifically a cooler that utilizes the cooling capacity of a freezer. Background Technology

[0002] Air conditioners, freezers, and refrigerators are common household refrigeration appliances with built-in cooling functions. Different types of freezers operate on different principles. For example, common compressor refrigerators use a compressor to work on the refrigeration system, allowing the refrigerant to absorb heat and achieve cooling. Semiconductor freezers, on the other hand, utilize the Peltier effect at the junction of a PN-type semiconductor to achieve cooling.

[0003] These refrigeration devices, except for air conditioners, store the generated cold air inside the cabinet to preserve food. They cannot provide the cold air to the outside. Therefore, when a family needs cool air to lower the indoor temperature, they can only turn on the air conditioner, which increases electricity consumption and requires the cost of purchasing an air conditioner.

[0004] Chinese utility model patent CN216281810U describes an improved air conditioner, comprising an air conditioning unit and a freezer unit. The air conditioning unit is vertically connected to the freezer unit via a lifting mechanism. The air conditioning unit is used to cover or open the opening of the freezer unit and to extract cold fluid from the freezer unit for refrigeration. The freezer unit is used for refrigerating food. It utilizes a submersible pump to supply cold water from a water tank into a bellows. A fan is activated, and hot air from the environment enters the air conditioning unit through the air inlet of the casing. The hot air passes through the gaps between the bellows to form cold air, which is then blown out from between the louvers. The drawbacks of this structure are: 1. During heat exchange in the air conditioning unit, the refrigerant needs to be extracted from the water tank and circulated. This causes the temperature inside the water tank to rise rapidly, requiring the freezer unit's refrigeration system to operate continuously to maintain a constant temperature, increasing power consumption. 2. The addition of the water tank, the water it fills, the submersible pump, and the lifting mechanism not only increases the overall weight, making it difficult to move, but also increases the power consumption of the submersible pump, increasing the burden on consumers. 3. Since the refrigerant is drawn outside the water tank for heat exchange, the temperature at the junction of the upper part of the water tank and the heat exchange area will change significantly. Even if the refrigerant is air, the water tank cannot be used as a food storage space.

[0005] Therefore, it is necessary to design a cooler that can reduce the cooling time of the freezer section, increase the storage space of the freezer section, and be lightweight while utilizing the cooling capacity of the freezer. Summary of the Invention

[0006] The purpose of this application is to propose a cold air cooler that utilizes the cooling capacity of a freezer to perform heat exchange inside the freezer and reduce the working time of the freezer's refrigeration system.

[0007] This application is implemented as follows: a cold air blower that utilizes the cooling capacity of a freezer includes a heat exchange box. The heat exchange box is divided into an air outlet chamber and an air inlet chamber. At least one heat exchange main pipe located inside the freezer is installed outside the air outlet chamber. The air inlet and air outlet of the heat exchange main pipe are connected to the air inlet chamber and the air outlet chamber, respectively. The upper end of the air outlet chamber is open, and a guide shroud is installed at the open end. An exhaust fan is installed at the outlet of the guide shroud.

[0008] A sealed precooling chamber is provided between the air outlet chamber and the air inlet chamber. Except for the upper end face, the inner walls of the other end faces of the precooling chamber are provided with a heat insulation layer. The precooling chamber is connected to the heat exchange main pipe through heat exchange branch pipes. The upper end face of the precooling chamber is made of heat-conducting material.

[0009] The air inlet of the heat exchange main pipe is connected to the air inlet pipe located in the air inlet chamber, and the air inlet pipe is connected to the air inlet chamber. The air outlet of the heat exchange main pipe is connected to the air outlet pipe located in the pre-cooling chamber, and the air outlet pipe is connected to the air outlet chamber.

[0010] An exhaust port is provided in the pre-cooling chamber, and a sealing plug is installed inside the exhaust port.

[0011] The air outlet of the heat exchange main pipe is exposed outside the freezer body. A valve is installed on the air outlet. The inlet end of the valve is connected to the air outlet, and the outlet end of the valve is connected to the air inlet end of the air outlet pipe. The inner end of the air outlet pipe extends into the pre-cooling chamber. An air outlet is installed at the inner end of the air outlet pipe. The air outlet of the air outlet is led out from the upper surface of the pre-cooling chamber into the air outlet chamber.

[0012] The air inlet of the heat exchange main pipe is exposed outside the freezer body. A valve is installed on the air inlet. The outlet end of the valve is connected to the air inlet, and the inlet end of the valve is connected to the air inlet end of the air inlet pipe. The air inlet end of the air inlet pipe is located in the air inlet chamber.

[0013] The main heat exchange pipe is also equipped with another air outlet, which is exposed outside the freezer body. The air outlet is equipped with a valve, the inlet end of which is connected to the air outlet, and the outlet end of which is connected to the air inlet end of the heat exchange branch pipe. The inner end of the heat exchange branch pipe extends into the pre-cooling chamber.

[0014] When multiple heat exchange main pipes are installed, air outlet pipes corresponding to the heat exchange main pipes are installed in the precooling chamber, and air outlets corresponding to the air outlet pipes are evenly distributed on the upper surface of the precooling chamber.

[0015] By implementing the above technical solution, this application achieves heat exchange between the main heat exchange pipe and the air inside the heat exchange box within the freezer. A fan then draws air from the heat exchange pipe and blows it outwards. This heat exchange method prevents the temperature inside the freezer from dropping rapidly, allowing the freezer's refrigeration system to operate intermittently and reducing power consumption. Furthermore, it eliminates the need for power-intensive submersible pumps or air pumps; a fan is sufficient for heat exchange. The overall cost is low, the weight is light, the structure is simple, and it is easy to modify. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the description of this application, it should be understood that the terms "center", "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 the present invention 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.

[0023] Example: Figure 1-3As shown, the air cooler that uses the cooling capacity of the freezer includes a heat exchange box 3. The body 17 of the heat exchange box 3 is divided into an air outlet chamber 4 and an air inlet chamber 6 by a partition. At least one heat exchange main pipe 14 located inside the freezer 1 is provided outside the air outlet chamber 4. The air inlet and air outlet of the heat exchange main pipe 14 are connected to the air inlet chamber 6 and the air outlet chamber 4, respectively. The upper end of the air outlet chamber 4 is open, and a guide shroud 7 is provided at the open end. An exhaust fan 8 is provided at the outlet of the guide shroud 7.

[0024] Furthermore, a sealed pre-cooling chamber 5 is provided between the air outlet chamber 4 and the air inlet chamber 6. Except for the upper end face, the inner walls of all other end faces of the pre-cooling chamber 5 are provided with an insulation layer. The pre-cooling chamber 5 is connected to the main heat exchange pipe 14 via a heat exchange branch pipe 13. The upper end face of the pre-cooling chamber 5 is made of a heat-conducting material, such as a metal plate, or other heat-conducting materials may also be used. The heat exchange branch pipe 13 can slowly guide the air that has already undergone heat exchange in the main heat exchange pipe 14 into the pre-cooling chamber 5 for storage.

[0025] Furthermore, the air inlet of the heat exchange main pipe 14 is connected to the air inlet pipe 12 located in the air inlet chamber 4, and the air inlet pipe 12 is connected to the air inlet chamber 4. The air outlet of the heat exchange main pipe 14 is connected to the air outlet pipe 16 located in the pre-cooling chamber 5, and the air outlet pipe 16 is connected to the air outlet chamber 6. This arrangement ensures that the temperature inside the air outlet pipe 16 is the same as the temperature inside the pre-cooling chamber 5, allowing for rapid blowing of cold air when the induced draft fan 8 is started.

[0026] With the above settings, when cold air needs to be drawn out, the temperature inside the air outlet chamber 4 and the air outlet duct 16 is lower than the room temperature, so that a cold air flow can be formed quickly, instead of having to wait a period of time to form cold air like an air conditioner.

[0027] Furthermore, an exhaust port 10 is provided in the pre-cooling chamber 5, and a sealing plug is sealed inside the exhaust port 10. The cold air in the pre-cooling chamber 5 can be slowly released through the exhaust port 10. This release method will not cause the refrigeration system 2 of the freezer 1 to work frequently. When it is necessary to slowly lower the indoor temperature, the sealing plug can be opened to allow the interior of the pre-cooling chamber 5 to be connected to the outside. At this time, the refrigeration system 2 maintains a low-frequency operation state, which is suitable for use when going to work. This way, the temperature in the home can be kept at a relatively low level after returning home from get off work.

[0028] Furthermore, the air outlet of the heat exchange main pipe 14 is exposed outside the cabinet of the freezer 1. A valve 15 is installed on the air outlet. The inlet end of the valve 15 is connected to the air outlet, and the outlet end of the valve 15 is connected to the air inlet end of the air outlet pipe 16. The inner end of the air outlet pipe 16 extends into the pre-cooling chamber 5. An air outlet 9 is installed at the inner end of the air outlet pipe 16. The air outlet of the air outlet 9 is led out from the upper end face of the pre-cooling chamber 5 into the air outlet chamber 4.

[0029] Furthermore, the air inlet of the heat exchange main pipe 14 is exposed outside the cabinet of the freezer 1. A valve 15 is installed on the air inlet. The outlet end of the valve 15 is connected to the air inlet, and the inlet end of the valve 15 is connected to the air inlet end of the air inlet pipe 12. The air inlet end of the air inlet pipe 12 is located inside the air inlet chamber 6.

[0030] Furthermore, another air outlet is provided on the heat exchange main pipe 14. The air outlet is exposed outside the cabinet of the freezer 1. A valve 15 is provided on the air outlet. The inlet end of the valve 15 is connected to the air outlet, and the outlet end of the valve 15 is connected to the air inlet end of the heat exchange branch pipe 13. The inner end of the heat exchange branch pipe 13 extends into the pre-cooling chamber 5.

[0031] The valve 15 controls the opening and closing of the air outlet, preventing excessive heat loss from the freezer and thus preventing frequent operation of the refrigeration system when this invention is not in use. The valve 15 can be a solenoid valve. The specific control circuit of the solenoid valve and the exhaust fan 8 is not the focus of this invention and will not be described in detail here. Existing control circuits can be used to control the opening and closing of the solenoid valve and the operation of the exhaust fan 8. The valve 15 can also be any valve in the prior art, such as a ball valve, and its opening and closing can be manually controlled.

[0032] like Figure 3 As shown, when multiple heat exchange main pipes 14 are provided, air outlet pipes 16 corresponding to each heat exchange main pipe 14 are provided in the precooling chamber 5, and air outlet heads 9 corresponding to each air outlet pipe 16 are evenly distributed on the upper surface of the precooling chamber 5. This allows the induced draft fan 8 to evenly draw air from the heat exchange main pipes 14 when it is working.

[0033] Before use, the heat exchange main pipe 14 needs to be installed inside the freezer 1, with its two air outlets and one air inlet located outside the freezer 1. Then, the two air outlets are connected to the air outlet pipe 16 and the heat exchange branch pipe 13 respectively via connector 18, and the air inlet is connected to the air inlet pipe 12. After assembly, first disconnect the valve 7 connected to the air outlet pipe 16 and the air inlet pipe 12, keeping the heat exchange main pipe 14 connected to the pre-cooling chamber 5. After standing for a period of time, the cold air will lower the temperature inside the pre-cooling chamber 5, at which point the refrigeration system 2 operates at low power consumption. When it is necessary to lower the room temperature, the sealing plug at the exhaust port 10 can be opened to connect the pre-cooling chamber 5 to the outside, slowly lowering the indoor temperature.

[0034] When a rapid reduction in indoor temperature is needed, close valve 7 at heat exchange branch pipe 13 and open valves at air outlet pipe 16 and air inlet pipe 12 to connect air inlet chamber 6 and air outlet chamber 4. Then, start the exhaust fan 8 to expel air from air outlet chamber 4. Since the upper surface of pre-cooling chamber 5 is made of heat-conducting material, the temperature in air outlet chamber 4 and air outlet pipe 16 is lower than room temperature. At the same time, heat exchange occurs between the air outlet pipe 14 and the refrigerant in freezer 1, resulting in lower air temperature drawn out from air outlet 9. This air is then drawn into the room by exhaust fan 8, thus rapidly reducing room temperature. During this process, since the refrigerant in freezer 1 does not need to be extracted, the temperature drop inside freezer 1 is smaller, allowing refrigeration system 2 to maintain intermittent cooling and reducing energy consumption.

[0035] The above technical features constitute the embodiments of this application, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the needs of different situations.
