Description

[Technical Field]

[0001] This utility model relates to a refrigerator. [Background Technology]

[0002] Currently, refrigerators, especially car refrigerators, generally use two cooling methods: air cooling and direct cooling. Air cooling typically uses a fan to blow cold air into the refrigerator compartment. For example, in patent number 202421145372.9, a car refrigerator with a sliding door, the fan is located on the side wall, using convection to blow or draw cold air into the storage compartment. This method allows cold air to quickly enter the storage compartment, preventing icing, but it requires strict control over the cold airflow channel, resulting in higher production costs. Direct cooling, on the other hand, has lower production costs but less precise temperature control. [Utility Model Content]

Detailed Implementation Methods

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0025] Example 1, such as Figures 1 to 4As shown, a uniform temperature direct cooling refrigerator includes a box body 1, which is square in shape. The box body 1 is equipped with a compressor 2, a condenser 3, and an evaporator 4. The box body 1 has an opening at the top and an inner liner 5 exposed at the top opening for placing items to be preserved. The inner liner 5 has an opening at the top and a frame inside to facilitate the placement of items and prevent direct contact with the inner wall of the inner liner 5, thus preventing freezing damage. A lid 6 is rotatably provided on the box body 1 to cover the top opening of the inner liner 5. The evaporator 4 is tubular and evenly wound around the outer wall of the inner liner 5. The lid 6 is equipped with a convection fan 7 that allows air to circulate within the inner liner 5. To prevent the airflow from the convection fan 7 from blowing directly onto the items inside the inner liner 5, the convection fan 7 is located in the middle of the lid 6. The side of the convection fan 7 facing the inner liner has an air intake 71. The convection fan 7 is spaced apart from the end face of the lid 6 and forms an air outlet 72 on its side. The convection fan 7 draws air upward from the middle of the inner liner 5, and then the airflow flows to the periphery of the inner liner 5 through the guiding effect of the top surface of the lid 6, and passes through the side walls of the inner liner 5. The airflow moves downwards, creating a circulating airflow that flows upwards from the center, laterally along the top wall, downwards along the side walls, and then to the bottom wall. This circulating airflow within the inner liner 5 minimizes the temperature difference between the edges and the center, achieving uniform temperature control. A temperature sensor 73 is located at the air intake 71, allowing for more accurate temperature detection. This facilitates the control of the compressor 2, condenser 3, and evaporator 4, thereby controlling the temperature within the inner liner 5 more precisely.

[0026] To facilitate the making of slushies, the upper surface of the lid 6 is provided with a slushie trough 61 with an opening at the top for placing iced beverage bottles. An ultrasonic device 62 is located at the bottom of the slushie trough 61. The bottom of the beverage bottle contacts the ultrasonic device 62, and the vibration of the ultrasonic device 62 turns the frozen water inside the beverage bottle into slushies, thus giving the container multiple functions for convenient use. For ease of use, the inner liner 5 has two compartments: a refrigerator compartment and a freezer compartment. The temperature inside the refrigerator compartment is typically above 0°C, and the temperature inside the freezer compartment is typically below 0°C. In this embodiment, a convection fan 7 is located on the lid 6 corresponding to the freezer compartment; however, a fan can also be installed in the refrigerator compartment. The bottom wall of the refrigerator compartment has multiple interconnected water channels 51, drain holes 52 that communicate with the water channels 51, and a sieve 53 that blocks the drain holes 52. The drain holes 52 connect to the outside of the refrigerator body 1 for easy drainage of wastewater. Typically, the drain holes 52 are located in the middle of the bottom of the inner liner 5. Two lids 6 and two inner liner 5 are provided, one for each of them. The ultrasonic device 62 is located on the lid 6 above the freezer compartment. For easy installation and a compact structure, a side cover 11 is provided at the top of the body 1. The side cover 11 has two annular openings, which correspond one for each of the two inner liners 5. The lid 6 is hinged to the side cover 11. The side cover 11 is provided with a touch panel 12 and a USB interface 13. The temperature or working mode can be controlled by the touch panel 12, and the USB interface 13 allows the refrigerator to be used as a car refrigerator.

[0027] For ease of handling, handles 14 are rotatably provided on two opposite side walls of the box body 1, wheels 15 are provided at the bottom of the box body 1, and a pull rod 16 is provided on one side wall of the box body 1, which is coaxially hinged to the handles 14. The handles 14 facilitate the handling of the refrigerator, and the pull rod 16 can be used to support the box body 1. It is easy to use. The pull rod 16 is coaxially hinged to one of the handles 14, which is compact and easy to install.

[0028] To ensure a compact structure and easy installation, a heat-dissipating shell 17 is provided on one side of the housing 1. The heat-dissipating shell 17 is detachably installed on the lower right corner of one side of the housing 1 (as shown in the diagram). The compressor 2 and condenser 3 are located inside the heat-dissipating shell 17. The heat-dissipating shell 17 also has a cooling fan and heat dissipation mesh 18. Hot air flows out through the heat dissipation mesh 18. Wheels 15 are provided on the heat-dissipating shell 17 for easy installation.

[0029] Example 2, as Figure 5-8As shown, the difference from Embodiment 1 is that Embodiment 2 has only one inner liner, and the ultrasonic device is detachable. Specifically, the ultrasonic device 62 is located on the upper surface of the housing 1. The upper surface of the housing 1 has a receiving groove 19, in which an ultrasonic mounting housing 63 is installed. An ice-making slush tank 61 is located on the ultrasonic mounting housing 63. The ice-making slush tank 61 is a circular groove with an opening at the top. The bottom of the ultrasonic mounting housing 63 has an upper power connector 64 for the ultrasonic device 62, and the bottom of the receiving groove 19 has a lower power connector that is connected to a power source and electrically connected to the upper power connector 64. After plugs 65, the lower power plug 65, and the upper power plug 64 are plugged in, power is supplied, thus connecting the ultrasonic device 62 to the power supply. The upper power plug 64 and the lower power plug 65 are fixed together by magnetic attraction. The upper power plug 64 is provided with a conductive protrusion and a conductive groove for inserting the conductive protrusion. After the upper power plug 64 and the lower power plug 65 are magnetically attracted, the conductive protrusion is inserted into the conductive groove, and the end faces of the upper power plug 64 and the lower power plug 65 are in contact with each other. After plugging in, the upper power plug 64 and the lower power plug 65 can be electrically connected. For easy fixation, the bottom of the receiving groove 19 is provided with a lower plug hole 20. The side wall of the lower plug 65 is provided with a lower elastic protrusion 66 that can elastically compress against the lower plug hole 20 when the lower plug 65 is inserted into it. The lower elastic protrusion 66 is composed of two bent and connected spring pieces. The two spring pieces form a triangular shape on the side wall of the lower plug 6. When the lower end of the lower plug 65 is inserted downward into the lower plug hole 20, the lower elastic protrusion 66 is compressed against the inner side wall of the lower plug hole 20. After the lower elastic protrusion 66 protrudes out of the lower plug hole 20, the elastic protrusion 66 returns to its original shape. A positioning notch can be set in the lower plug hole 20. When inserted, the lower elastic protrusion 66 is inserted along the notch for easy positioning. The bottom of the ultrasonic mounting housing 63 is provided with an upper plug hole 67. The side wall of the upper power plug 64 is provided with an upper elastic protrusion 68 that can elastically compress against the upper plug hole 67 when the upper power plug 64 is inserted into the upper plug hole 67. The structure and installation process of the upper elastic protrusion 68 are the same as those of the lower elastic protrusion 66. The upper end of the ultrasonic mounting housing 63 is hinged with a cover 69 that can be placed on the ice slush tank 61. After opening the cover 69, some water is added to the ice slush tank 61, and then an iced beverage bottle is placed in the ice slush tank 61. The ultrasonic device 62 is started, and after ice slush is formed, the iced beverage bottle is removed, and the cover 69 is closed. If it is necessary to drain the water, the ultrasonic mounting housing 63 can be removed and the water can be poured out. After the water is poured out, the ultrasonic device 62 is put back, and the upper power plug 64 and the lower power plug 65 are magnetically attracted to each other, making it convenient to use. To facilitate observation of the working status, the ultrasonic mounting housing 63 is equipped with a circuit board 70 electrically connected to the ultrasonic device 62 and the upper power plug 64, an LED lamp 80 electrically connected to the circuit board 70, and a light-transmitting block 81 that can transmit light from the LED lamp 80. The light-transmitting block 81 can be made of black light-transmitting material, or it can be said that the light-transmitting block 81 has an opening to allow the light from the LED lamp 80 to shine out.The light-transmitting block 81 is fixed on the ultrasonic mounting housing 63. The light-transmitting block 81 has an annular side surface and a bottom surface, with the bottom surface pressing against the ultrasonic device 62.
