Detailed Implementation

[0020] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, construction, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0021] This utility model embodiment provides a horizontal direct-cooling freezer, such as Figure 1 As shown, the horizontal direct-cooling freezer includes: a cabinet body 10, a cabinet door 20 rotatably mounted on the cabinet body 10, a refrigeration module (not shown in the figure) detachably mounted inside the cabinet body 10, and a fan assembly 30 integrated inside the cabinet door 20.

[0022] The cabinet 10 has a storage space 11 and an installation space (not shown in the figure) located behind the storage space 11. The storage space 11 is used to store items that need to be refrigerated at low temperatures. The installation space is used to store the refrigeration module. The installation space has an air inlet that communicates with the storage space 11. The refrigeration module provides cooling capacity in the form of cold air to the storage space 11 through the air inlet.

[0023] The top of the cabinet 10 has an opening 13 that connects to the outside, and the opening 13 connects the storage space 11 and the installation space.

[0024] Cabinet door 20 is rotatably mounted on top of cabinet 10 to open and close opening 13. Cabinet door 20 closes opening 13 to prevent cold air leakage inside cabinet 10.

[0025] like Figure 1 , 2As shown, the fan assembly 30 includes a wind chamber 2 and a stirring fan 3 rotatably installed in the wind chamber 2. The stirring fan 3 includes an air inlet 31 for airflow input and an air outlet 32 ​​for airflow output. The air outlet 32 ​​faces upward toward the cabinet door 20 and has a gap with the cabinet door 20 so that the cold air drawn in by the stirring fan 3 can be released from the air outlet 32. The air inlet 31 faces downward toward the storage space 11. The stirring fan 3 also includes an impeller 33 that rotates about an axis extending in the vertical direction. When the impeller 33 rotates about its own axis, the air in the storage space 11 is drawn into the stirring fan 3 from the air inlet 31 and released into the wind chamber 2 from the air outlet 32.

[0026] The air chamber 2 has an air inlet 21 and an air outlet 22 that are in fluid communication with the storage space 11. The air inlet 21 is arranged between the air inlet end 31 and the storage space 11, allowing air in the storage space 11 to enter the stirring fan 3 from the air inlet end 31 under the suction of the stirring fan 3. The air outlet 22 is arranged circumferentially around the air outlet end 32 and is in fluid communication with the storage space 11. Air released from the air outlet end 32 enters the air chamber 2 and is then released from the air outlet 22 into the storage space 11. In this embodiment of the present invention, multiple air outlets 22 are arranged circumferentially on the air outlet end 32 to allow cold air to be released into the storage space 11.

[0027] The blower assembly 30 also includes a blower housing 4 that covers the outside of the mixing blower 3, providing protection. The blower housing 4 is installed on the inner wall of the cabinet door 20 and is shaped like an inverted frustum. It includes a circular first portion 41 and a second portion 42 surrounding the first portion 41. The second portion 42 has an upper end 421 that connects to the cabinet door 20 and a lower end 422 that connects to the first portion 41. The diameter of the circle formed by the upper end 421 is larger than the diameter of the circle formed by the lower end 422. An air inlet 21 is located on the first portion 41, and multiple air outlets 22 are located on the second portion 42.

[0028] like Figure 2 As shown, the air inlet 21 has a first vertically extending axis X1, and each air outlet 22 has an inclined second axis X2. The multiple air outlets 22 are arranged at intervals around the first axis X1; the second axis X2 and the first axis X1 have an angle α of 30°-60°. The fan assembly 30 draws cold air from the storage space 11 from bottom to top, and then releases the drawn cold air into the air chamber 2. The inverted frustum-shaped fan casing 4 causes the cold air in the air chamber 2 to circulate in a spiral shape, and then diffuses outwards from the first axis X1 through the multiple air outlets 22, which plays a role in stirring the cold air in the storage space 11 and realizing the uniform distribution of cold air in the horizontal direct-cooling freezer.

[0029] like Figure 1As shown, the inner wall of the cabinet door 20 has a mounting groove 5 corresponding to the fan housing 4. The mounting groove 5 is recessed inward and defines the air outlet chamber 2 with the fan housing 4. When the cabinet door 20 is closed (opening 13), at least part of the fan assembly 30 is located in the storage space 11. It is installed using the unused space inside the cabinet door 20, and the mounting groove 5 on the cabinet door 20 effectively reduces the space occupied by the fan assembly 30 in the storage space 11, avoiding obstruction of the storage of items in the storage space 11.

[0030] The mixing fan 3 is installed on the fan housing 4. The impeller 33 of the mixing fan 3 is rotatably installed on the first part 41 of the fan housing 4. There is a gap between the air outlet 32 ​​of the mixing fan 3 and the bottom of the mounting groove 5.

[0031] A fan control device (not shown in the figure) is also installed on the cabinet 10. The fan control device is electrically connected to the stirring fan 3. The fan control device is configured to detect the opening and closing of the cabinet door 20 and control the operation of the stirring fan 3 based on the detection result. When the fan control device detects that the cabinet door 20 is closed (opening 13), it controls the power supply circuit of the stirring fan 3 to supply power normally, and the impeller of the stirring fan 3 rotates to ensure that the cold air in the storage space 11 is evenly distributed. When the fan control device detects that the cabinet door 20 is open (opening 13), it controls the power supply circuit of the stirring fan 3 to stop supplying power, and the impeller of the stirring fan 3 stops rotating to ensure the safety of the user when the cabinet door 20 is open and to prevent the loss of cold air. In this embodiment of the present invention, the fan control device is a magnetic switch or a ball switch to respond promptly when the cabinet door is opened or closed.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. The scope of protection of this utility model is defined by the appended claims, specification, and their equivalents.
