[0033] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0034] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "inner", "outer", etc. in the present utility model is based on the positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the devices and elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0035] In the description of the present utility model, it should be understood that the terms "first", "second", etc. are used in the present utility model to describe various information, but these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0036] In the related art, the condensation part of the refrigeration system in a freezer is generally placed at the bottom. In order to maximize the volume of the cabinet body, a dedicated heat dissipation air duct is often not provided, and both air intake and exhaust are carried out on the back of the cabinet body. This requires a certain gap between the back and the top of the freezer. Otherwise, problems such as increased power consumption, slowed refrigeration speed, and overheat protection of the compressor may occur due to poor heat dissipation. To solve this problem, manufacturers often add a local protrusion to the back of the freezer. The protrusion can be non-removable or removable. However, this will occupy the installation space of the freezer. Therefore, a freezer that does not occupy additional space and can be directly installed against the wall is needed.

[0037] Based on this, as Figures 1 to 4As shown in the figure, an embodiment of the present utility model provides a freezer, which includes a cabinet body 100, a refrigeration component 200 and an air guiding channel 300. The cabinet body 100 is provided with a cabinet door 1 and a machine cabin 2. The cabinet door 1 is arranged on the front of the cabinet body 100, and the machine cabin 2 is arranged at the bottom of the cabinet body 100. The bottom wall of the cabinet body 100 is respectively provided with a first air suction port 3 and a first air discharge port 4, and the first air suction port 3 and the first air discharge port 4 are respectively communicated with the machine cabin 2; the refrigeration component 200 includes a compressor 21 and a condenser 22, and the compressor 21 and the condenser 22 are arranged in the machine cabin 2; the air guiding channel 300 is arranged at the bottom of the cabinet body 100, and the air guiding channel 300 has a first air inlet 31 and a first air outlet 32. The first air inlet 31 is communicated with the first air discharge port 4, and the first air outlet 32 extends out of the bottom of the cabinet door 1.

[0038] In this embodiment, the cabinet body 100 is the main structure of the freezer. The cabinet door 1 has a glass surface and is arranged on the front of the cabinet body 100 and can be rotated open to facilitate the user to take the items in the cabinet body 100. The machine cabin 2 is arranged at the bottom of the cabinet body 100 for placing the refrigeration component 200. An evaporator chamber 400 is provided at the upper part of the cabinet body 100 for installing an evaporator 41. The function of the evaporator 41 is to evaporate the liquid refrigerant into a low-temperature and low-pressure gas. When the liquid refrigerant enters the evaporator 41, it evaporates and absorbs the external heat under the low-pressure state, thereby reducing the temperature inside the cabinet body 100. The refrigeration component 200 includes a compressor 21 and a condenser 22. The compressor 21 sucks the low-pressure refrigerant gas from the evaporator 41 and then compresses it into a high-pressure gas, and this process will increase the temperature of the gas. The condenser 22 is used for heat dissipation to cool the refrigerant into a liquid state. The liquid refrigerant coming out of the condenser 22 flows into the capillary tube, and after the throttling reduction of the capillary tube, it flows into the evaporator 41 again. Then the cycle process enables the temperature inside the freezer to be reduced. The four components of the compressor 21, the condenser 22, the capillary tube and the evaporator 41 cooperate with each other to form a refrigeration cycle system in the freezer, thereby realizing the control and adjustment of the temperature inside the freezer.

[0039] Based on the above technical solution, in this embodiment, the first air inlet 3 and the first air outlet 4 of the cabinet 100 are respectively arranged at the bottom of the cabinet 100 and communicated with the engine room 2, and the air guiding channel 300 is arranged at the bottom of the cabinet 100. During use, when the compressor 21 is started, the ambient air from the outside is sucked into the interior of the engine room 2 through the first air inlet 3, passes through the condenser 22 and the compressor 21, and exchanges heat with the refrigeration component 200 in the engine room 2, thereby forming hot air with a higher temperature. The hot air flows through the first air inlet 31 from the first air outlet 4, enters the air guiding channel 300, and is discharged outward from the first air outlet 32, thereby improving the smoothness of exhaust air and preventing the hot air from circulating in the engine room 2 or at the bottom of the cabinet 100 and affecting the heat dissipation effect of the freezer. In this embodiment, the first air inlet 3 and the first air outlet 4 are arranged at the bottom of the engine room 2, and air is sucked and exhausted from the bottom of the cabinet 100 instead of from the back of the cabinet 100, so that the cabinet 100 can be installed against the wall, and thus there is no need to provide protrusions on the back of the cabinet 100, reducing the installation space of the freezer.

[0040] In this embodiment, as Figure 2 shown, the cabinet 100 is placed entirely on the ground, and a partition is provided at the lower position of the cabinet 100 to form the air guiding channel 300. The engine room 2 (the first air outlet 4) is communicated with the air guiding channel 300 (the first air inlet 31), and the hot air in the engine room 2 is discharged through the air guiding channel 300 at the bottom of the cabinet 100.

[0041] In this embodiment, as Figures 1 to 3 shown, an evaporator fan 42 and a water receiving tank 43 are further provided at the upper part of the cabinet 100. When the refrigerant in the evaporator 41 evaporates, it absorbs the surrounding heat, reducing the temperature of the surrounding air. The evaporator fan 42 blows these low-temperature air to all corners inside the freezer to achieve rapid refrigeration. Among them, a condenser fan 23 and a water receiving box 24 are provided in the engine room 2, and a water outlet pipe 44 is connected between the water receiving tank 43 and the water receiving box 24. During refrigeration, the condensed water generated by the evaporator 41 flows to the water receiving tank 43 by gravity, and then flows to the water receiving box 24 on the compressor 21 through the water outlet pipe 44, and the water in the water receiving box 24 is evaporated dry by the heat generated by the compressor 21 and the condenser fan 23.

[0042] As a preferred implementation manner, as Figure 1 shown, support feet 5 and air guiding pipes 6 are provided at the bottom of the cabinet 100. The support feet 5 are used to support the cabinet 100, and the air guiding pipes 6 are arranged between the support feet 5 and the ground to form the air guiding channel 300.

[0043] Specifically, the supporting feet 5 serve as the supporting points of the cabinet body 100, enabling the cabinet body 100 to be stably placed, preventing the cabinet body 100 from shaking or toppling due to uneven ground or external vibrations, and enhancing the stability of the cabinet body 100 itself. Different from directly arranging a partition at the lower position of the cabinet body 100, in this embodiment, at the bottom of the cabinet body 100, a draft tube 6 is connected from the position of the first air outlet 4 by using the gap formed by the supporting feet 5 and the ground to form an air guiding channel 300. The first air inlet 31 is the inlet of the draft tube 6, and the first air outlet 32 is the outlet of the draft tube 6.

[0044] As an implementation manner, as Figure 1 or Figure 2 shown, the draft tube 6 further has a second air outlet 33. The second air outlet 33 is arranged on the side wall of the draft tube 6, and the second air outlet 33 extends from the draft tube 6 to the bottom of the cabinet door 1 and faces the cabinet door 1.

[0045] Specifically, after the hot air in the machine cabin 2 is led out by the draft tube 6, there are two air outlets. The hot air can be discharged either from the first air outlet 32 or from the second air outlet 33. When the hot air is discharged outward from the first air outlet 32 towards the environment.

[0046] After refrigeration for a period of time, fog water generally appears on the surface of the cabinet door 1 of the refrigerator. When there is a lot of fog water, it will drip onto the floor, affecting the beauty of the refrigerator and causing inconvenience in use. To solve the problem of fogging and condensation on the cabinet door 1, heating wires are generally installed on the cabinet door 1 to heat and defog the glass, but this will cause a large amount of energy loss. There are also cases of using multi-layer low-e glass or vacuum glass to actively reduce condensation by improving the heat insulation effect of the cabinet door 1, but this method is too costly.

[0047] Based on this, in this embodiment, the second air outlet 33 is arranged to face the cabinet door 1. When the hot air is discharged from the second air outlet 33, the hot air blows directly against the glass surface of the cabinet door 1. By utilizing the temperature characteristics of the hot air and the temperature difference effect between the hot air and the glass surface, the fog on the cabinet door 1 is removed, condensation is reduced, so that the cabinet door 1 is clear and transparent, improving the visibility and recognition of the items inside the refrigerator for consumers. Consumers can view the goods without opening the cabinet door 1, avoiding frequent opening of the door to check, reducing unnecessary energy consumption and cold loss, and thus reducing the energy consumption of the refrigerator.

[0048] As an implementation manner, as Figure 1 shown, a first valve 34 is provided at the first air outlet 32, and a second valve 35 is provided at the second air outlet 33; the refrigerator includes a control component (not shown in the drawings), and the control component is used to control the opening or closing of the first valve 34 and the second valve 35.

[0049] Specifically, when there is no fog on the cabinet door 1 and defogging is not required, the control component controls the second valve 35 to close and the first valve 34 to open, so that all the hot air is directly discharged to the outside from the first air outlet 32, preventing unnecessary hot air from blowing onto the glass surface of the cabinet door 1 and causing heat conduction into the cabinet body 100, and avoiding unnecessary energy loss. When there is fog on the cabinet door 1 and defogging is required, the control component controls the second valve 35 to open and the first valve 34 to close, so that all the hot air is discharged to the cabinet door 1 from the second air outlet 33 to defog the cabinet door 1 and avoid affecting vision and the customer experience.

[0050] In this embodiment, by respectively arranging valves at the two air outlets of the air guiding pipe 6 and precisely controlling these two valves by using the control component, the discharge path of the hot air can be flexibly adjusted according to actual needs, enabling the refrigerator to optimize the discharge of hot air based on factors such as the current environmental conditions, the internal temperature of the refrigerator, and user requirements, thereby improving the operating efficiency of the refrigerator and reducing its energy consumption. Among them, the first valve 34 and the second valve 35 can adopt electric doors, which have the characteristics of quick response and precise control. When the control component issues an instruction, the electric door can quickly open or close to facilitate the rapid and timely adjustment of the hot air discharge path.

[0051] As an implementation manner, as Figure 4 shown, at least one second air discharge port 7 is further provided on the bottom wall of the cabinet body 100, and the at least one second air discharge port 7 is arranged at an interval from the first air discharge port 4.

[0052] Specifically, the second air discharge port 7 is not connected to the air guiding pipe 6. When the cabinet door 1 does not require defogging, the first valve 34 and the second valve 35 can be controlled to close, so that all the hot air is directly discharged from the second air discharge port 7 without passing through the air guiding pipe 6, enabling the heat to be directly and efficiently discharged into the environment and reducing the heat accumulation in the engine room 2.

[0053] As an implementation manner, an air outlet bar (not shown in the drawings) is provided at the bottom of the cabinet door 1, the second air outlet 33 communicates with the air outlet bar, and the air outlet bar is provided with an opening facing the cabinet door 1.

[0054] Specifically, an air outlet bar is provided at the bottom of most of the cabinet doors 1 of the cabinet body 100. After the hot air comes out from the second air outlet 33 of the air guiding pipe 6, it enters the air outlet bar and blows towards the cabinet door 1 from the opening of the air outlet bar to defog the glass surface of the cabinet door 1.

[0055] As an implementation manner, as Figure 4 shown, an extension pipe 8 is connected to the air guiding pipe 6, the extension pipe 8 is connected to the second air outlet 33, the extension pipe 8 extends along the horizontal direction of the cabinet door 1 at the bottom of the cabinet door 1, and the extension pipe 8 is provided with a plurality of third air outlets 36 facing the cabinet door 1, and the plurality of third air outlets 36 are arranged at intervals.

[0056] Specifically, in some embodiments, there is no air outlet grille at the bottom of the cabinet door 1 of the cabinet body 100. In this case, the present embodiment sets an extension pipe 8 at the bottom of the cabinet door 1 of the cabinet body 100. After the hot air comes out from the second air outlet 33 of the air duct 6, it first enters the extension pipe 8 horizontally extending from the bottom of the cabinet door 1, and then faces upward from multiple third air outlets 36 on the extension pipe 8 to the surface of the cabinet door 1. The entire surface of the cabinet door 1 is defogged from bottom to top at different positions in the horizontal direction, and the defog effect is more comprehensive.

[0057] Among them, a plurality of third air outlets 36 arranged at intervals are provided so that hot air can be blown evenly to the cabinet door 1 from different horizontal positions, thereby achieving comprehensive demisting of the entire surface of the cabinet door 1. Compared with a single or a small number of air outlets, it is more efficient and uniform, and improves the demisting effect.

[0058] In practical applications, the position of the third air outlet 36 on the extension tube 8 can be adjusted. For example, if a certain area of the cabinet door 1 is more likely to generate fog, the number and position of the third air outlet 36 in this area can be increased to better meet the defogging requirements.

[0059] For the same purpose, the present embodiment may also provide a row of parallel air ducts 6 at the bottom of the cabinet 100, wherein the first air outlet 32 of each air duct 6 faces the cabinet door 1, and defogs the entire surface of the cabinet door 1 from bottom to top at different positions in the horizontal direction.

[0060] As an implementation mode, the air duct 6 is provided with an exhaust device and a heating device (not shown in the drawings), wherein the exhaust device is used to accelerate the air flow velocity of the hot air; and the heating device is used to heat the temperature of the hot air to improve the demisting effect.

[0061] As an implementation method, Figure 3 and Figure 5 As shown, Figure 3 This is a schematic diagram of the back structure of the refrigerator without the rear cover 9. Figure 5 1 is a schematic diagram of the structure of the rear cover plate 9. The cabinet 100 is provided with a rear cover plate 9, which is arranged on the back of the cabin 2 to cover the cabin 2, and the rear cover plate 9 is provided with a second air inlet 10.

[0062] This embodiment is provided with two air intakes, the first air intake 3 is provided at the bottom of the cabin 2, and the second air intake 10 is provided on the back side of the cabin 2 (on the rear cover 9). By providing two air intakes, sufficient cooling air can be provided to the equipment from different angles and positions.

[0063] As an implementation manner, the cabinet body 100 is further provided with a temperature and humidity sensor 11 for monitoring the surface temperature of the cabinet body 100; the control component is configured to control one of the first valve 34 and the second valve 35 to open and control the other of the first valve 34 and the second valve 35 to close according to the surface temperature of the cabinet body 100.

[0064] Specifically, by arranging the temperature and humidity sensor 11 inside the cabinet body 100, the surface temperature of the cabinet body 100 can be monitored in real time and accurately, providing precise input data for the control component so that it can adjust the temperature inside the cabinet body 100 according to actual needs. For example, when the surface temperature of the cabinet door 1 is higher than the dew point temperature of the air outside the cabinet door 1, the control component determines that fog has formed on the cabinet door 1 and needs to defog the cabinet door 1. At this time, the second valve 35 is controlled to open and the first valve 34 is controlled to close, so that the hot air is discharged entirely to the cabinet door 1 from the second air outlet 33 to defog the cabinet door 1. Similarly, when the surface temperature of the cabinet door 1 is lower than the dew point temperature of the air outside the cabinet door 1, the control component determines that no fog has formed on the cabinet door 1, and then the second valve 35 is controlled to close and the first valve 34 is controlled to open, so that the hot air is directly discharged to the outside entirely from the first air outlet 32.

[0065] In this embodiment, the first valve 34 and the second valve 35 will not be closed simultaneously, and at least one of the valves is ensured to be in an open state to prevent the hot air from having no outlet for discharge.

[0066] As an implementation manner, the temperature and humidity sensor 11 includes a first sensor and a second sensor; the first sensor is arranged on the outer surface of the cabinet body 100 to monitor the temperature, humidity and dew point temperature outside the cabinet body 100; the second sensor is arranged on the inner surface of the cabinet body 100 to monitor the temperature and humidity inside the cabinet body 100.

[0067] Specifically, by arranging the first sensor and the second sensor on the inner and outer surfaces of the cabinet body 100 respectively, the temperature inside and outside the cabinet body 100 can be monitored in real time and accurately. This arrangement form of dual sensors can provide more comprehensive and accurate temperature data and reliable temperature data information for the control component.

[0068] As an implementation manner, in this embodiment, the heat transfer coefficient between the sensor (the second sensor) inside the cabinet body 100 and the glass surface of the cabinet door 1 can also be directly utilized to indirectly calculate the temperature of the outer surface of the cabinet door 1.

[0069] Exemplarily, if the temperature of the outer surface of the cabinet door 1 is less than or equal to the dew point temperature outside the cabinet body 100, it is determined that fog is generated on the glass surface of the cabinet door 1. At this time, the second valve 35 is controlled to open and the first valve 34 is controlled to close, so that hot air blows towards the cabinet door 1 for defogging; conversely, if the temperature of the outer surface of the cabinet door 1 is greater than the dew point temperature outside the cabinet body 100, it is determined that no fog is generated on the glass surface of the cabinet door 1. At this time, the second valve 35 is controlled to close and the first valve 34 is controlled to open, so that the hot air is directly discharged to the outside.
