Description

Technical Field

[0001] The utility model relates to the technical field of wine cabinets, in particular to a constant temperature and humidity wine cabinet. Background Art

[0002] The best storage temperature for red wine is about 10-15℃, and the best storage humidity is generally above 50%. People can use a constant temperature and humidity wine cabinet to store red wine. Conventional constant temperature and humidity wine cabinets are equipped with a temperature control module, a humidification module and a controller. A temperature and humidity sensor is also provided inside the cabinet. The controller controls the connection between the temperature control module and the humidification module, and connects the temperature and humidity sensor. The temperature and humidity sensor detects the temperature and humidity inside the cabinet. The controller obtains the temperature and humidity information from the temperature and humidity sensor, and then controls the temperature control module to maintain the temperature inside the cabinet between 10 and 15 degrees Celsius according to the temperature and humidity information. The humidification module is controlled to humidify the inside of the cabinet until the humidity inside the cabinet exceeds 50%, achieving "constant temperature and humidity". The temperature control module generally includes an evaporator, a compressor, a condenser, a throttle valve and a blower. A heat exchange channel is provided in the cabinet, and the evaporator and the blower are arranged in the heat exchange channel. In summer, the temperature is high, and the temperature control module is in cooling mode. The blower draws air from the entrance of the heat exchange channel and sends the air to the evaporator. The evaporator absorbs the heat from the air and cools it down to cold air. The cold air is discharged from the outlet of the heat exchange channel to the inside of the cabinet. The evaporator transfers the absorbed heat to the condenser, and the condenser dissipates the heat outside the cabinet. In winter, the temperature is lower, and the temperature control module sometimes needs to be switched to heating mode. In heating mode, the condenser absorbs the heat outside the cabinet and transfers it to the evaporator. The evaporator transfers the heat to the air inside the cabinet to heat up the air. In this process, the condenser is prone to frost due to its low temperature. Some temperature control modules have a defrosting function, but the water produced after defrosting is generally discharged directly and cannot be effectively used. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a constant temperature and humidity wine cabinet, which can effectively utilize the water generated after defrosting on the condenser.

[0004] In order to solve the above technical problems, the constant temperature and humidity wine cabinet of the utility model includes a temperature control module, a humidification module and a controller, which is also provided with a temperature and humidity sensor inside. The controller controls the connection of the temperature control module and the humidification module, and connects the temperature and humidity sensor. The cabinet is provided with a heat exchange channel, and the inlet and outlet of the heat exchange channel are respectively connected to the inside of the cabinet. The blower and evaporator of the temperature control module are arranged in the heat exchange channel, the air inlet of the blower is aligned with the inlet of the heat exchange channel, and the air outlet is aligned with the evaporator. The condenser tube of the condenser of the temperature control module is "W"-shaped, and the fins of the condenser are provided with a heating wire for heating and defrosting the condenser, and a funnel is provided under the condenser to receive the water generated after defrosting; the cabinet is provided with a water storage tank at the outlet of the heat exchange channel, and the bottom of the funnel is connected to the water storage tank to guide the received water into the water storage tank; a power supply for powering the heating wire is provided above the heating wire, and a power supply switch is provided on the power supply, and the controller controls the connection of the power supply switch.

[0005] Furthermore, a metal tube is sheathed outside the heating wire, and an insulating material is filled between the heating wire and the metal tube.

[0006] Furthermore, a tube-through hole is opened on the fin of the condenser, and the metal tube passes through the tube-through hole; and heat-conductive silica gel is filled between the metal tube and the hole wall.

[0007] Furthermore, a cover plate is provided at the notch of the water storage tank; a transverse electric push rod is included to drive the connected cover plate, and a controller controls the connected electric push rod to control the electric push rod to drive the cover plate to move transversely away from the notch.

[0008] Furthermore, the humidification module includes a humidifier and a water tank for supplying water to the humidifier, the outlet of the humidifier is connected to the inside of the cabinet, and the controller controls the connection of the humidifier.

[0009] Furthermore, the water tank is arranged below the water storage tank, and a water pipe is arranged between the two. The upper end of the water pipe is the liquid inlet end, which extends to the top of the water storage tank, and the lower end is the liquid outlet end, which is connected to the water tank. The water pipe guides the water on the top of the water storage tank to the water tank.

[0010] Furthermore, a liquid level meter is provided in the water storage tank, and the controller is connected to the liquid level meter; a water pump is included, the liquid inlet end of the water pump is connected to the water tank, and the liquid outlet end is connected to the water storage tank. The controller controls the water pump to control the water pump to pump the water in the water tank to the water storage tank.

[0011] When the temperature control module is switched to the heating mode, the controller controls the power switch to conduct so that the power supply supplies power to the heating wire, and the heating wire is used to heat the condenser to defrost the condenser. Since the power supply is located above the heating wire, it will not be wetted by the defrosted water. Since the condenser tube of the condenser is "W" shaped, even if the defrosted water flows along the condenser tube, it will only flow to the bottom of the condenser tube and then drip down, and will not flow to other components of the temperature control module. The funnel receives the water generated after defrosting and guides the water to the water storage tank. The condenser absorbs the heat outside the cabinet and transfers it to the evaporator. The blower extracts the air inside the cabinet from the entrance of the heat exchange channel and sends the air to the evaporator. The evaporator transfers the heat to the air to heat the air into hot air, and the hot air is discharged from the outlet to the inside of the cabinet. In this process: the hot air passes above the water storage tank, which can not only heat the water in the water storage tank to make the water in the water storage tank evaporate quickly, but also bring the evaporated water vapor into the cabinet. In this way, the water after the condenser defrosts is effectively used to humidify the inside of the cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further described in detail below in conjunction with specific implementation methods.

[0022] Constant temperature and humidity wine cabinet Figure 1 and Figure 7 , including a temperature control module 1, a humidification module 2 and a controller (not shown in the figure), which includes a cabinet 4 and a cabinet door 40. A temperature and humidity sensor 3 is also provided inside the cabinet 4. The controller controls the connection between the temperature control module 1 and the humidification module 2, and connects the temperature and humidity sensor 3. The temperature and humidity sensor 3 detects the temperature and humidity inside the cabinet 4. The controller obtains the temperature and humidity information from the temperature and humidity sensor 3, and then controls the temperature control module 1 to maintain the temperature inside the cabinet 4 between 10 and 15 degrees Celsius according to the temperature and humidity information, and controls the humidification module 2 to humidify the inside of the cabinet 4 until the humidity inside the cabinet 4 exceeds 50%, so as to achieve constant temperature and humidity.

[0023] See Figure 5 and Figure 6 The cabinet 4 is provided with a vertical heat exchange channel 41, the upper end of the heat exchange channel 41 is provided with an inlet 411, and the lower end is provided with an outlet 412, the inlet 411 and the outlet 412 are connected to the inside of the cabinet 4 respectively, and filters 413 and 414 are provided at the inlet 411 and the outlet 412 respectively. Figure 6 and Figure 7 The temperature control module 1 is a prior art, comprising an evaporator 11, a compressor 12, a condenser 13, a throttle valve 14 and a four-way reversing valve (not shown in the figure) connected together, and also comprising a blower 15 and a fan 16. The evaporator 11 and the blower 15 are arranged in the heat exchange channel 41, the air inlet 151 of the blower 15 is aligned with the inlet 411 of the heat exchange channel 41, and the air outlet 152 is aligned with the evaporator 11. The condenser 13 and the fan 16 are as shown in FIG. Figure 3As shown, it is arranged on the rear wall of the cabinet 4, and the controller controls the connection of the compressor 12, the four-way reversing valve, the blower 15 and the fan 16. Since these are all existing technologies, they are not described in detail. In summer, the temperature is high, and the temperature control module 1 is in the cooling mode. The blower 15 extracts the air inside the cabinet 4 from the inlet 411 of the heat exchange channel 41 and sends the air to the evaporator 11. The evaporator 11 absorbs the heat of the air and cools it into cold air. The cold air is discharged from the outlet 412 of the heat exchange channel 41 to the inside of the cabinet 4. The evaporator 11 transfers the absorbed heat to the condenser 13, and the condenser 13 dissipates the heat to the air outside the cabinet 4. The fan 16 blows air backwards to dissipate the heat for the condenser 13. In winter, the temperature is lower, and the temperature control module 1 sometimes needs to switch to the heating mode. In the heating mode, the condenser 13 absorbs the heat outside the cabinet 4 and transfers it to the evaporator 11. The blower 15 also draws the air inside the cabinet 4 from the inlet 411 of the heat exchange channel 41 and sends the air to the evaporator 11. The evaporator 11 transfers the heat to the air inside the cabinet 4 to heat the air into hot air, and the hot air is discharged from the outlet 412 of the heat exchange channel 41 to the inside of the cabinet 4.

[0024] See Figure 2 , Figure 3 and Figure 4 When the temperature control module 1 is switched to the heating mode, the condenser 13 of the temperature control module 1 is prone to frost due to the low temperature. For this reason, the constant temperature and humidity wine cabinet is provided with an electric heating wire 51, a metal tube 53 is sheathed outside the electric heating wire 51, and a magnesium oxide insulating material 54 is filled between the electric heating wire 51 and the metal tube 53. A through-tube hole 133 is opened on the fin 132 of the condenser 13, and the metal tube 53 passes through the through-tube hole 133. The metal tube 53 and the hole wall of the through-tube hole 133 are filled with thermal conductive silica gel 56. The electric heating wire 51 is arranged on the fin 132 of the condenser 13 in this way. A power supply 52 is provided above the electric heating wire 51 and the metal tube 53. The power supply 52 is installed on the rear wall of the cabinet 4. It is connected to the electric heating wire 51 in the metal tube 53 through cables 522 and 523, and can supply power to the electric heating wire 51. A power switch 521 is provided on the power supply 52, and the controller controls the connection of the power switch 521. When the temperature control module 1 is switched to the heating mode, the controller controls the power switch 521 to be turned on so that the power supply 52 supplies power to the heating wire 51, and the heating wire 51 is used to heat the condenser 13 to defrost the condenser 13. Since the power supply 52 is located above the heating wire 51, it will not be wetted by the defrosted water. The condenser tube 131 of the condenser 13 is a "w"-shaped hard metal tube. Even if the defrosted water flows along the condenser tube 131, it will only flow to the bottom of the condenser tube 131 and then drip down, and will not flow to other components of the temperature control module 1.

[0025] See Figure 3 and Figure 6A funnel 6 is provided below the condenser 13, and a water storage tank 42 is provided below the outlet 412 of the heat exchange channel 41 of the cabinet 4. The bottom of the funnel 6 is connected to the water storage tank 42 through a water pipe 61. When the electric heating wire 51 defrosts the condenser 13, the funnel 6 receives the water generated after defrosting and guides the water to the water storage tank 42. Figure 6 and Fig. 9 The notch 420 of the water tank 42 is covered with a cover plate 421, and the cabinet 4 is provided with a horizontal electric push rod 422 on the side of the cover plate 421. The electric push rod 422 drives the cover plate 421, and the controller controls the electric push rod 422. Figure 6 and Figure 8 When the humidity inside the cabinet 4 is lower than 50%, the controller controls the electric push rod 422 to drive the cover plate 421 to move horizontally away from the notch 420 of the water tank 42. When the hot air in the heat exchange channel 41 is discharged from the outlet 412 to the inside of the cabinet 4, the hot air passes over the notch 420 of the water tank 42. The heat of the hot air will be transferred to the water in the water tank 42, thereby heating the water in the water tank 42 and causing the water in the water tank 42 to evaporate quickly. The evaporated water vapor passes upward through the notch 420 of the water tank 42 and enters the heat exchange channel 41. The hot air in the heat exchange channel 41 brings the water vapor into the cabinet 4, thereby effectively utilizing the water after defrosting in the condenser 13 to humidify the inside of the cabinet 4. Figure 6 and Fig. 9 When the humidity inside the cabinet 4 is higher than 50%, the controller controls the electric push rod 422 to drive the cover plate 421 to move horizontally to cover the notch 420 of the water tank 42. Then, the evaporated water vapor in the water tank 42 cannot pass through the notch 420 of the water tank 42 upwards into the heat exchange channel 41, and cannot enter the interior of the cabinet 4, thus stopping humidification of the cabinet 4.

[0026] See Figure 1 and Figure 7 The humidification module 2 includes a humidifier 21 and a water tank 22 for supplying water to the humidifier 21. The outlet of the humidifier 21 is connected to the inside of the cabinet 4 through a water mist pipe 23. The controller controls the connection of the humidifier 21. When the humidity inside the cabinet 4 is lower than 50%, the controller controls the humidifier 21 to humidify the inside of the cabinet 4. Figure 7 and Figure 8 The water tank 22 is arranged below the water storage tank 42, and a water pipe 43 is arranged between the two. The upper end 431 of the water pipe 43 is the liquid inlet end, extending to the top of the water storage tank 42, and the lower end 432 is the liquid outlet end, connected to the water tank 22. When the water level in the water storage tank 42 is high, the water pipe 43 can guide the water at the top of the water storage tank 42 to the water tank 22 to prevent the water from overflowing from the top of the water storage tank 42. Figure 6 and Figure 7A liquid level meter 425 is provided in the water storage tank 42, and the controller controls the connection to the liquid level meter 425 to obtain water level information in the water storage tank 42 from the liquid level meter 425. The wine cabinet includes a water pump 44, the liquid inlet end of the water pump 44 is connected to the water tank 22 through a water inlet pipe 441, and the liquid outlet end is connected to the water storage tank 42 through a water outlet pipe 442. The controller controls the connection to the water pump 44. When the water level in the water storage tank 42 is low, the controller controls the water pump 44 to pump the water in the water tank into the water storage tank 42 to replenish the water in the water storage tank 42.

[0027] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
