[0031] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0032] High humidity in a refrigerator typically refers to an average relative humidity of over 90%. During the cooling process in the refrigerator compartment, moisture inside the compartment condenses on the evaporator surface as the air circulates, causing the humidity inside the refrigerator to drop rapidly. When the refrigerator stops cooling, the humidity inside the compartment rises again. Therefore, the humidity inside the refrigerator fluctuates periodically with the cooling cycle, making it difficult to maintain a high humidity level in the refrigerator compartment.
[0033] Therefore, this application provides a refrigerator that primarily maintains a high-humidity environment inside the refrigerator by replenishing water from outside the refrigerator compartment. Specifically, in conjunction with... Figure 1 , Figure 2 , Figure 3 Figure 5 and Figure 6 As shown, this application provides a refrigerator 1000, comprising:
[0034] A refrigerator liner 110, wherein the refrigerator liner 110 has a refrigerator chamber S1;
[0035] Sprayer 130, the sprayer 130 is disposed on the refrigerator inner liner 110 and configured to spray water onto the refrigerator chamber S1;
[0036] The cabinet 120 has a receiving cavity S3; the refrigerator inner liner 110 is disposed inside the cabinet 120; the top of the cabinet 120 includes an outer surface 121 and an inner surface 122, and a water storage tank S2 formed from the outer surface 121 toward the inner surface 122, and the nozzle 130 is connected to the water storage tank S2.
[0037] In the technical solution of this application embodiment, a water storage tank S2 is formed on the top outer side of the box 120 from the outer surface 121 toward the inner surface 122; the water in the water storage tank S2 is sprayed through the nozzle 130 into the refrigeration chamber S1 of the refrigeration inner liner 110 inside the box 120 so that the refrigeration chamber S1 can be in a high humidity environment.
[0038] In this embodiment, when the refrigerator stops cooling, the humidity inside the refrigerator will increase again, and the spray nozzle 130 will stop spraying water to increase the humidity through the defrost water from the evaporator. Of course, in some embodiments, if the refrigerator 1000 is not in defrost mode or the refrigerator fan is not running, the defrost water from the evaporator is generated slowly or the defrost water enters the refrigerator compartment slowly. In this case, the spray nozzle 130 can also spray water to maintain a high humidity environment in the refrigerator compartment S1 through external water.
[0039] In some embodiments, during refrigeration, the moisture in the refrigeration chamber S1 condenses onto the surface of the evaporator with the air circulation, and the humidity inside the chamber drops rapidly. At this time, the nozzle 130 is turned on, and external water from the top of the chamber 120 is used to replenish the refrigeration chamber S1, so that the refrigeration chamber S1 is in a high humidity environment during refrigeration, thus overcoming the technical problem in the prior art that it is difficult to maintain a high humidity state in the refrigeration chamber during refrigeration.
[0040] In addition, the water tank S2 is exposed to the environment, which can absorb heat from the environment. This allows the water delivered to the refrigerator to be at a higher temperature, which can evaporate more quickly and help increase humidity.
[0041] In some embodiments, the spray head 130 is an automatic spray head 130. The refrigerator 1000 is also equipped with a controller, which sends a spray signal to the automatic spray head 130; when the automatic spray head 130 receives the spray signal, it turns on. The controller can be configured to control the automatic spray head 130 to turn on when humidification is required in the refrigerator compartment. The situations where humidification is required in the refrigerator compartment include at least one of the following: 1. When the refrigerator 1000 is set to high humidity operation, the refrigerator is in cooling mode; 2. The humidity in the refrigerator compartment is lower than the preset humidity; 3. When the refrigerator 1000 is set to high humidity operation, the refrigerator stops cooling, the refrigerator 1000 is in non-defrost operation, or the refrigerator fan stops operating.
[0042] As an optional implementation of the above embodiments, combined with Figure 1 and Figure 4 As shown, the water storage tank S2 has an opening S21 and a bottom wall S22; the opening S21 is located on the outer surface 121; the area of the opening S21 is larger than the area of the bottom wall S22. In the technical solution of this application embodiment, the area of the opening S21 is set to be larger than the area of the bottom wall S22, so that the water storage tank S2 has a larger opening, which makes it easier for the water in the water storage tank S2 to absorb heat from the external environment and make it easier to evaporate.
[0043] As an optional implementation of the above embodiments, combined with Figure 1 and Figure 4 As shown, the water storage tank S2 also includes a tank sidewall S23, which extends from the tank opening S21 to the tank bottom wall S22. The angle between the tank sidewall S23 and the tank bottom wall S22 is an obtuse angle, such that the area of the tank opening S21 is larger than the area of the tank bottom wall S22; at the same time, it facilitates the gradual accumulation of water towards the tank bottom wall S22 under the action of gravity when water is sprayed. In some embodiments, the obtuse angle can be set between 105° and 150°.
[0044] As an optional implementation of the above embodiments, combined with Figure 1 and Figure 4As shown, the water storage tank S2 has a bottom wall S22, which includes a first region S221 and a second region S222 connected to each other. An interface S24 is provided on the first region S221, and the interface S24 is connected to the nozzle 130. The first region S221 is lower than the second region S222. In this embodiment, placing the interface S24 within the lower first region S221 allows water to flow to the interface S24 under gravity and be discharged after the nozzle 130 is turned on, thus reducing water accumulation in the water storage tank S2. For example, combined with... Figure 4 As shown, the second region S222 surrounds the first region S221 and is set higher than the first region S221.
[0045] As an optional implementation of the above embodiments, combined with Figure 1 and Figure 4 As shown, the water storage tank S2 also includes a tank sidewall S23, which extends from the tank opening S21 to the second region S222. In the embodiment, the first region S221 is provided with an interface S24 for discharging water into the nozzle 130. The tank sidewall S23 extends from the tank opening S21 to the second region S222, giving the water storage tank S2 a larger water storage space and facilitating the downward flow of water within the tank. This allows the water to gradually converge towards the bottom wall S22 under gravity during spraying, reducing water residue.
[0046] As an optional implementation of the above embodiments, combined with Figure 1 and Figure 4 As shown, the interface S24 includes a drain hole that connects to the nozzle 130; the first region S221 includes a drain surface that extends from the second region S222 to the drain hole, and the angle between the drain surface and the horizontal plane is an obtuse angle. In this embodiment, water will flow into the drain hole and then into the nozzle 130 under the guidance of gravity through the drain surface, thus preventing water from accumulating in the water tank S2.
[0047] As an optional implementation of the above embodiments, combined with Figure 2 and Figure 3 As shown, the nozzle 130 is located on the top of the refrigerator inner liner 110. In this embodiment, the water tank S2 is located on the top of the cabinet 120, and the nozzle 130 is also located on the top of the refrigerator inner liner 110, which can reduce the water transmission path and the pipeline structure, making the structure simpler and more compact.
[0048] In some embodiments, the top of the refrigerated inner liner 110 is also provided with an air outlet for the refrigerated compartment, which facilitates the diffusion and distribution of moisture throughout the refrigerated compartment space with the air circulation, thereby improving the uniformity of humidity throughout the space.
[0049] As an optional implementation of the above embodiments, the nozzle 130 is an atomizing nozzle 130. The atomizing nozzle 130 is used to atomize water, making the sprayed atomized water more likely to increase the humidity in the refrigeration chamber S1. The atomizing nozzle 130 can be an ultrasonic atomizing nozzle 130, an electrode atomizing nozzle 130, etc.
[0050] As an optional implementation of the above embodiments, Figure 7 As shown, the nozzle 130 includes a body 131 and a plurality of spray arms 132 disposed on the body 131. The spray arms 132 are arranged at an angle to or parallel to the horizontal direction, and the plurality of spray arms 132 are spaced apart around the body 131. The body 131 is connected to the water storage tank S2 and is fixed to the refrigerator inner liner 110. By providing a plurality of spray arms 132 extending in different directions on the body 131, the water can be sprayed in different directions, thereby making the humidity in the refrigerator compartment uniform.
[0051] In this embodiment, the spray arm 132 is equipped with a water spray channel and a water spray hole. The water spray channel is connected to the water inlet channel inside the main body 131. The water inlet channel is connected to the water storage tank S2. Water in the water spray channel is sprayed out into the refrigerator compartment through the water spray hole. In this embodiment, an atomizing component can also be provided between the water spray channel and the water inlet channel. The atomizing component is used to atomize the water, and the atomized water is sprayed out through the water spray hole. The atomizing component can be an ultrasonic atomizing component, an electrode atomizing component, etc.
[0052] In this embodiment, the spray arms 132 can also be configured with individual spray modes, meaning each spray arm 132 can spray water independently. For example, valves can be installed on the spray arms 132, and these valves can be opened and closed independently. This setting can be achieved by controlling the valves based on humidity measured by a humidity sensor, so that the corresponding valve is opened in the area requiring humidification.
[0053] As an optional embodiment of the above embodiments, the refrigerator 1000 further includes a condenser, which is disposed around the periphery of the water tank S2. The condenser, as an important component of the refrigerator 1000's refrigeration system, functions to release the heat from the refrigerant compressed by the compressor into the environment; it is a heat-releasing device in the refrigeration system. By placing the condenser around the periphery of the water tank S2, the water in the water tank S2 can absorb heat, making it easier for the water delivered to the refrigerator compartment to reach a higher temperature and evaporate more quickly.
[0054] As an optional implementation of the above embodiments, the refrigerator 1000 further includes a water supply pipe connected to the cabinet 120 and communicating with the water storage tank S2. In some embodiments, the water supply pipe can be connected to a water source. In other embodiments, the water supply pipe can also be connected to a water receiving tray of the refrigerator 1000, which is used to collect defrost water. A water pump and / or valve are provided on the water supply pipe. The water supply pipe is used to deliver water to the water storage tank S2.
[0055] In some embodiments, when humidification is required, a water supply pipe delivers water to a water storage tank S2.
[0056] In some embodiments, the water tank S2 is covered with an openable cover.
[0057] In some embodiments, the refrigerator 1000 is equipped with a refrigerator compartment humidity sensor to control the amount of water sprayed by the nozzle 130 by detecting the humidity.
[0058] In other embodiments, multiple nozzles 130 can be configured, each corresponding to a different refrigerated compartment within the refrigeration chamber S1. Each nozzle 130 is connected to a main pipe via its own connecting pipe, and the main pipe is connected to a water tank S2. By detecting the humidity of each refrigerated compartment, it is determined whether the corresponding compartment needs increased humidity; if so, the corresponding nozzle 130 is activated.
[0059] In some embodiments, excess moisture can also be drained by detecting humidity. When the humidity in the refrigerator compartment is too high, the refrigerator fan is turned off during evaporator defrosting, preventing defrost water from entering the refrigerator compartment and draining the excess moisture.
[0060] The refrigerator provided in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
