[0002] With the continuous development of refrigerator technology, people are not only demanding higher performance from refrigerators, but also increasing their requirements for their appearance and aesthetic placement within the home. Built-in refrigerators, because they do not take up too much space and are aesthetically pleasing without appearing obtrusive, have become increasingly popular in recent years. While refrigerator manufacturers on the market have developed many models of built-in refrigerators, a satisfactory solution to the problem of residual heat in these models remains elusive.

[0003] Built-in refrigerators are surrounded by walls on three sides, and the heat emitted by their compressors and condensers can easily accumulate in the compressor compartment, posing a safety hazard.

[0004] Therefore, how to design an embedded refrigerator and its base structure that can solve the problem of heat accumulation and safety hazards in embedded refrigerators is a technical problem that the industry urgently needs to solve. Utility Model Content

[0026] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0028] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0029] Built-in refrigerators are becoming increasingly popular due to their space-saving design and aesthetic appeal. However, with three sides enclosed by walls, the heat generated by the compressor and condenser is difficult to dissipate, posing a safety hazard.

[0030] To address the aforementioned problems, this utility model proposes a base structure for an embedded refrigerator. Please refer to [link / reference]. Figure 2 , Figure 3 and Figure 4 It has a base 1, which has a housing for housing the compressor 2 and the condenser 3;

[0031] It also includes a ventilation circuit installed on the base 1, which connects the accommodating chamber to the outside.

[0032] The main problem with built-in refrigerators is that the heat generated by the compressor 2 and condenser 3 is difficult to dissipate, causing it to accumulate in the storage compartment. This invention, by adopting the above-mentioned ventilation circuit design, can connect the storage compartment with the outside. In this way, after the compressor 2 and condenser 3 generate heat, the heat can be discharged to the outside through the ventilation circuit, avoiding the safety hazards caused by the accumulation of heat in the storage compartment.

[0033] Please see Figure 1 and Figure 3 The base structure of the embedded refrigerator proposed in this utility model also includes an air intake fan 4 and an air outlet fan 5 disposed in the storage chamber, and the ventilation circuit is connected to the air intake fan 4 and the air outlet fan 5.

[0034] Here, the intake fan 4 is used to draw air from the outside, and the exhaust fan 5 is used to exhaust air from the containment chamber. With the design of the intake fan 4 and the exhaust fan 5, the airflow entering the ventilation circuit can be guided to form a circulation loop, which can carry the heat in the containment chamber to the outside.

[0035] Furthermore, without the intake fan 4 and exhaust fan 5, the temperature inside the container is relatively high. At this time, the heat exchange efficiency between the condenser 3 and the surrounding environment is poor, which will affect the cooling effect of the refrigerator to a certain extent. After setting the intake fan 4 and exhaust fan 5, this utility model can accelerate the gas flow rate inside the container, improve the heat exchange efficiency of the condenser 3, and thus improve the cooling efficiency of the refrigerator.

[0036] In other words, with the design of the air intake fan 4 and the air outlet fan 5 in this utility model, not only can the heat in the room be removed in time to avoid safety hazards, but the cooling efficiency of the refrigerator can also be improved to a certain extent.

[0037] Please see Figure 1 and Figure 2 In this utility model, the base 1 adopts a hollow sandwich structure, and the air inlet fan 4 and the air outlet fan 5 are both connected to the hollow sandwich structure.

[0038] The hollow sandwich structure has an air inlet 6 and an air outlet 7 on the outward side. The hollow sandwich structure connects the air intake fan 4 to the air inlet 6 and the air outlet fan 5 to the air outlet 7.

[0039] Here, the present invention adopts the above-mentioned hollow sandwich structure. It only requires designing the lower part of the original base 1 as a hollow sandwich structure, without changing the shape of the base 1. That is, the present invention can assemble the embedded refrigerator normally without changing the original installation method of the embedded refrigerator and the base 1, without making any structural modifications to the embedded refrigerator.

[0040] Furthermore, the internal structure of the hollow sandwich structure is essentially a pipe, allowing airflow to pass through normally. In this invention, after the air intake fan 4 and the air inlet 6 are connected through the hollow sandwich structure, when the air intake fan 4 starts to draw air, the external airflow can enter the hollow sandwich structure through the air inlet 6, then reach the air intake fan 4 along the hollow sandwich structure, and finally enter the accommodating chamber.

[0041] After connecting the exhaust fan 5 to the air outlet 7, when the exhaust fan 5 starts to blow air, the airflow in the room can carry some heat, enter the hollow sandwich structure from the exhaust fan 5, and then go along the hollow sandwich structure to the air outlet 7, and carry the heat to the outside.

[0042] In other words, this utility model, through the design of the hollow sandwich structure, can form the ventilation circuit mentioned above, which is used to remove the heat contained in the room. In addition, by adopting this hollow sandwich structure, there is no need to adjust the structure and installation method of the embedded refrigerator, no extra labor is required, and the operation is simple.

[0043] Please see Figure 2 In addition, the present invention provides a heat insulation partition 8 in the middle of the hollow sandwich structure, which separates the air inlet 6 from the air outlet 7.

[0044] The purpose of setting the heat insulation partition 8 in this utility model is to separate the air inlet and air outlet in the hollow sandwich structure. As can be seen from the previous introduction, the air inlet of the hollow sandwich structure is drawn from the outside by the air inlet fan 4, and its temperature is not high. However, the air outlet of the hollow sandwich structure is vented to the receiving chamber by the air outlet fan 5. Since it carries some heat from the receiving chamber, it generally has a higher temperature. If the heat insulation partition 8 is not set between the air inlet 6 and the air outlet 7, heat exchange will occur between the air inlet and the air outlet in the hollow sandwich structure, thereby increasing the air inlet temperature. After the air inlet temperature increases, it will affect the heat exchange between the air inlet and the receiving chamber, thus affecting the heat dissipation effect.

[0045] By incorporating the aforementioned heat-insulating partition 8, this invention can prevent heat exchange between the air intake and exhaust, thus ensuring good heat dissipation for the accommodating room.

[0046] Please see Figure 1 and Figure 2 In this utility model, the base 1 is a stepped structure, and the back space between the upper and lower steps of the stepped structure forms an accommodating chamber.

[0047] The stepped structure used in this invention is mainly for better placement of the compressor 2 and condenser 3. If a traditional base structure, such as a flat structure, is used, the compressor 2 and condenser 3 can only be laid flat on the flat structure. When installing the cabinet of the built-in refrigerator, the position of the compressor 2 and condenser 3 will also affect its installation.

[0048] This utility model employs a stepped structure, which to a certain extent achieves a separation effect, allowing the compressor 2 and condenser 3 to be placed within the housing formed by the structure itself. Furthermore, because the stepped structure has a vertical surface, it also allows for better installation of the intake fan 4 and exhaust fan 5. If it were changed to a planar structure, since the intake fan 4 and exhaust fan 5 need to face directly into the housing, additional support structures would be required, increasing design costs.

[0049] In other words, the base 1 in this utility model is designed as a stepped structure, which makes it easier to install the compressor 2, condenser 3, intake fan 4 and exhaust fan 5, without the need to add other support structures, making the design simpler.

[0050] Please see Figure 3 The present invention also includes a plurality of foot pads 9 disposed at the bottom of the base 1, the foot pads 9 being installed at the bottom of the base 1 using a screw-type structure.

[0051] Here, the purpose of setting the foot pad 9 is to provide a certain support. The foot pad 9 adopts a screw structure because the screw structure can adjust the depth of the foot pad 9 embedded in the base 1 by twisting, thereby adjusting the height of the entire foot pad 9. That is, this utility model can adjust the height of the entire base 1 by setting the foot pad 9 to adapt to the installation of the built-in refrigerator.

[0052] Please see Figure 3 The condenser 3 in this utility model is a microchannel condenser, and a condenser fan 11 is also provided in the housing chamber, which is oriented towards the condenser 3.

[0053] In this invention, the condenser 3 is configured as a microchannel condenser, which has the following advantages compared to traditional condensers:

[0054] The microchannel structure can significantly increase the heat exchange area, making the contact between the refrigerant and the microchannel surface closer, reducing thermal resistance and improving the heat transfer coefficient. In other words, the microchannel condenser has high-efficiency heat exchange performance.

[0055] Microchannel condensers are only 1 / 3 to 1 / 2 the size and structure of traditional condensers, saving space in the housing.

[0056] In addition, microchannel condensers generally use aluminum alloy for heat transfer, which can save more than 20% to 30% of the cost compared to the materials used in traditional condensers.

[0057] In the above configuration, a condenser fan 11 is also installed in the housing, and the condenser fan 11 is positioned towards the condenser 3 to further improve the heat dissipation effect between the condenser 3 and the surrounding environment, thereby further improving the refrigeration capacity of the refrigerator.

[0058] In other embodiments of this utility model, dustproof nets are also provided on the outside of the air intake fan 4 and the air outlet fan 5.

[0059] The purpose of setting up this dustproof net is to prevent dust from entering the intake fan 4 and the exhaust fan 5, affecting their operation, and extending their lifespan to a certain extent.

[0060] Please see Figure 3 The present invention also includes a temperature sensor 10 disposed in the housing, and the opening and closing states of the air intake fan 4 and the air outlet fan 5 are set according to the detection results of the temperature sensor 10.

[0061] The purpose of setting the temperature sensor 10 in this invention is to more accurately control the temperature inside the housing, avoid excessively high temperatures inside the housing, and ensure that the compressor 2 and condenser 3 always operate within an optimal temperature range.

[0062] Based on the settings of the temperature sensor 10 described above, please refer to [link / reference]. Figure 5 The control process of the above-mentioned intake fan 4 and exhaust fan 5 in this utility model is as follows:

[0063] Temperature sensor 10 detects the temperature T inside the containment chamber and determines whether the temperature T inside the containment chamber is greater than the preset temperature t;

[0064] When the temperature T inside the containment chamber is determined to be greater than the preset temperature t, the intake fan 4 and the exhaust fan 5 are powered on. At this time, the intake fan 4 starts to introduce cold air from the outside and sends it into the containment chamber through the hollow sandwich structure of the base 1. The exhaust fan 5 starts to blow hot air out and sends it to the outside through the hollow sandwich structure of the base 1 to achieve the purpose of cooling the containment chamber.

[0065] When the temperature T inside the containment chamber is determined to be lower than the preset temperature t, the power is cut off to the intake fan 4 and the exhaust fan 5. At this time, there is no need to cool down the containment chamber, which can save some electricity.

[0066] In addition, this utility model also provides two fans in the hollow sandwich structure, which are used to supplement the condenser fan 11 when the ambient temperature is too high, causing the built-in refrigerator to be under heavy load or the condenser 3 to be dirty and clogged, so as to perform condensation heat exchange on the condenser 3 and improve the refrigeration efficiency of the refrigerator.

[0067] Please see Figure 6 The control flow for the two newly added wind turbines is as follows:

[0068] The maximum operating voltage TV of the condenser fan 11 is preset, and the operating voltage of the two fans in the mezzanine is tV.

[0069] Determine whether the preset temperature t is greater than the temperature T inside the containment room;

[0070] When the determination is yes (according to the appendix) Figure 5 In this process, the intake fan 4 and the exhaust fan 5 are turned off, and the two fans in the interlayer can assist in heat exchange for the condenser. The two fans in the interlayer are powered on to assist in heat exchange for the condenser. At this time, the problem of excessive noise caused by the condenser fan 11 being too fast in the built-in refrigerator can be reduced.

[0071] If the result is negative, the two fans in the interlayer are powered off to keep the built-in refrigerator running.

[0072] Based on the above design, this utility model also proposes an embedded refrigerator, which has the above-mentioned embedded refrigerator base structure.

[0073] In summary, compared with the prior art, the present invention has at least the following beneficial effects:

[0074] This invention adds a ventilation circuit to the base, which connects the housing containing the compressor and condenser to the outside, enabling timely removal of heat generated by the compressor and condenser and preventing heat accumulation. In addition, this invention connects an intake fan and an exhaust fan to the ventilation circuit, which increases the ventilation volume of the housing, thereby improving the heat exchange efficiency of the condenser and increasing the cooling capacity of the built-in refrigerator.

[0075] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
