[0038] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] See also Figure 1-Figure 8 As shown, an integrated cold and hot cabinet with switchable compression refrigeration and steam heating functions includes a cabinet body 11 and a storage cabinet 12 fixed in the cabinet body 11. The cold and hot cabinet also includes a base plate 13 fixed on the cabinet body 11, two sets of mounting components 14 installed on the base plate 13, a ventilation panel 15 installed in front of the cabinet body 11 by bolts, and an intelligent protection switch 16 installed on the ventilation panel 15.

[0040] A group of mounting components 14 on the bottom plate 13 is provided with a refrigeration component 2 for regulating the temperature in the locker 12, and another group of mounting components 14 on the bottom plate 13 is provided with a heating component 3 for regulating the temperature in the locker 12; the refrigeration component 2 includes a refrigeration combination frame 21 fixed on the mounting component 14, an evaporator 22 is fixed on the refrigeration combination frame 21, a condenser 23 connected to the evaporator 22 is also fixed on the refrigeration combination frame 21, and a compressor 24 is installed on the pipeline connecting the evaporator 22 and the condenser 23.

[0041] The heating component 3 includes a heating assembly frame 31 fixed on the mounting assembly 14, a heating pool 32 is fixed on the heating assembly frame 31, a heater 33 is installed in the heating pool 32, a water level sensing probe 34 for detecting the lowest water level in the heating pool 32 is installed in the heating pool 32, and a temperature sensing probe 35 for detecting the steam water temperature is installed in the heating pool 32.

[0042] The refrigeration component 2 is operated to cool down and adjust the temperature in the locker 12, so that the locker 12 is in the cooling mode, or the heating component 3 is operated to heat up and adjust the temperature in the locker 12, so that the locker 12 is in the heating mode. The temperature in the locker 12 is adjusted according to the storage needs. There is only one locker 12 in the cabinet 11, and the switching of the cooling or heating mode is realized by using one locker. Compared with the traditional mode, which requires a combination cabinet with a single cooling unit and a single heating unit, the use space and floor space are smaller, and the commodity price is lower. The cabinet 11 is made of 304 stainless steel, which is sprayed with plastic compared with aluminum plate and cold-rolled plate, has a longer service life, does not rust, and has a more beautiful appearance.

[0043] The cold and hot cabinets use electronic thermostats controlled by intelligent algorithms. Compared with traditional thermostats, they can more accurately control the hot and cold temperatures in the box. When cooling, they have more accurate temperature hysteresis control and intelligent frost time control, and more accurate start-stop ratio, so as to achieve energy saving and consumption reduction. In addition, an intelligent protection switch 16 is installed on the surface of the cabinet 11. Compared with the unprotected ordinary plugs of each single refrigeration and heating cabinet, it has a higher safety factor and can perform one-key rotation to switch the cooling and heating functions.

[0044] The refrigeration component 2 controls the circulation of the refrigerant through the evaporator 22, the condenser 23 and the compressor 24, and cooperates with the ventilation panel 15 to achieve air cooling. The operation of the refrigeration component 2 is more energy-saving. The use of an air-cooled condenser has better heat dissipation in harsh environments than a condenser attached to the inner wall of the box. The refrigeration system pressure is more stable and the freezing capacity is more easily guaranteed.

[0045] The present invention uses an air-cooled refrigeration evaporator system, which has greatly improved cooling speed, freezing capacity, storage temperature and power consumption compared with a direct cooling refrigeration method, and the items in the box are cooled more evenly.

[0046] The ventilation panel 15 adopts a single-sided circulation ventilation design. Compared with the traditional front-to-back ventilation design, it can achieve normal air intake, reduce re-inhalation, and the system has no high-pressure protection and can operate normally in embedded use environments and use environments where air is not circulated due to the placement of other items, store design structure, and the need to be used against the wall.

[0047] See also Figure 3 , Figure 15-18 As shown, a door assembly 4 capable of adjusting the size of the cooling air outlet of the locker 12 is installed inside the cabinet body 11 , and a fan 5 is installed on the door assembly 4 to control the flow of gas in the locker 12 and the cabinet body 11 .

[0048] According to the need to store items in the locker 12, the inlet and outlet air volume is adjusted. The door assembly 4 can control the air volume of the refrigeration assembly 2 in and out of the locker 12, thereby achieving the purpose of regulating the temperature in the locker 12. This function adjusts the opening and closing degree to a small extent when the items are to be dried by wind, and adjusts the opening and closing degree to a large extent when the items need to be cooled quickly. Compared with the refrigerator with direct cooling refrigeration method, it is more flexible and has selectivity.

[0049] See also Figure 15-18 As shown, the door assembly 4 includes a fixed door 41 fixed next to the storage cabinet 12, and an air outlet 42 corresponding to the air suction direction of the fan 5 is provided on the fixed door 41, and a return air outlet 43 is also provided on the fixed door 41. A strip groove 44 is provided on the fixed door 41, and a movable sliding column 45 is slidably installed in the strip groove 44, and a movable door 46 is fixedly installed on the movable sliding column 45, and the movable door 46 is attached to the surface of the fixed door 41; an upper vent 47 corresponding to the position of the air outlet 42 is provided on the mobile door 46, and a lower vent 48 corresponding to the position of the return air outlet 43 is provided on the mobile door 46.

[0050] The fixed door 41 is controlled to move in contact with the surface of the movable door 46, the upper vent 47 on the fixed door 41 moves and is misaligned with the air outlet 42 on the movable door 46, the lower vent 48 on the fixed door 41 moves and is misaligned with the return air outlet 43 on the movable door 46, the opening and closing degrees of the air outlet 42 and the return air outlet 43 are reduced, thereby achieving control of the air volume in and out of the locker 12.

[0051] See also Fig.17 and Fig.18 As shown, a displacement assembly 6 for controlling the movement of the movable door 46 is provided in the cabinet 11 .

[0052] The movable door 46 is controlled by the displacement assembly 6 to move in contact with the surface of the fixed door 41 , thereby adjusting the opening and closing degree of the air outlet 42 and the air return outlet 43 on the surface of the fixed door 41 .

[0053] See also Fig.17and Fig.18 As shown, the shift assembly 6 includes a support frame 61 fixed on the cabinet 11, a threaded rod 62 is rotatably installed on the support frame 61, an internal threaded column 63 is threadedly sleeved on the threaded rod 62, the internal threaded column 63 is slidably installed on the support frame 61, and a guide bracket 64 is fixedly installed on the internal threaded column 63, and the guide bracket 64 is fixedly connected to the movable cabin door 46.

[0054] A motor for controlling the rotation of the threaded rod 62 is installed on the support frame 61. The threaded rod 62 is controlled to rotate, and the internal threaded column 63 mounted on the threaded rod 62 moves laterally under the action of the threaded transmission. The internal threaded column 63 drives the movable cabin door 46 to move synchronously, thereby driving the movable cabin door 46 to slide and move on the surface of the fixed cabin door 41.

[0055] The heating component 3 realizes steam heating through the heating pool 32 and the heater 33. The steam heating is used. Compared with the PTC heating plate heating, the available volume is larger and the storage time is longer. The weight of the food will not be reduced by air drying, and the impact on the taste and appearance of the food will be reduced. A water level sensing probe 34 is provided in the heating pool 32. When the water level is lower than the probe position, a signal is instantly sent to the thermostat to stop heating and prevent dry burning. The temperature sensing probe 35 detects the steam water temperature in real time and synchronously. When the set temperature is reached, a signal is sent to the thermostat to stop heating. The more traditional PDC heating plate heating probe reads the air temperature. When the air temperature reaches the set temperature and stops heating, the heat inside the heating plate has not been completely dissipated. At this time, the temperature in the box will continue to rise. Therefore, the new intelligent limit-type water level sensing probe has more sensitive and more accurate temperature control than the air temperature probe.

[0056] When an operational failure occurs in the refrigeration component 2 or the heating component 3, the refrigeration component 2 and the heating component 3 can be quickly pulled out from the cabinet 11 through the installation component 14, and the refrigeration component 2 and the heating component 3 can be removed from the cabinet 11. The maintenance operation is convenient, and the installation and moving structure is stable, and the cold and hot cabinets are safe to use.

[0057] See also Figure 5 , Figure 6 , Figure 9-Figure 14 As shown, the installation component 14 includes a slide rail 141 installed on the base plate 13, a slide bar 142 is slidably installed on the slide rail 141, and the slide bar 142 is fixedly installed on the refrigeration combination frame 21 and the heating combination frame 31; a positioning mechanism 143 for limiting the moving position of the slide bar 142 is provided on the base plate 13, and a locking mechanism 144 for reinforcing the installation of the slide rail 141 is provided on the base plate 13.

[0058] By controlling the sliding bar 142 to slide on the slide rail 141, the refrigeration component 2 or the heating component 3 can be moved outward from the cabinet 11. Two positioning mechanisms 143 are provided on the bottom plate 13, which respectively position the maximum position of the sliding bar 142 moving toward the inside of the cabinet 11, and position the refrigeration component 2 and the heating component 3 moving toward the outside of the cabinet 11 for maintenance, so as to maintain the stability of the moving position of the refrigeration component 2 and the heating component 3 when they are installed in the cabinet 11 and pulled out for maintenance. If the refrigeration component 2 or the heating component 3 has a serious fault and needs to be disassembled for maintenance, the refrigeration component 2 and the heating component 3 can be removed from the cabinet 11 through the locking mechanism 144 for further maintenance. The locking mechanism 144 is easy to unlock and can assist the refrigeration component 2 and the heating component 3 to be stably installed in the cabinet 11.

[0059] See also Fig. 9 , Fig.10 and Fig.14 As shown, the positioning mechanism 143 includes an upper fixed bracket 1431 fixed on the sliding bar 142, a movable seat 1432 is fixedly installed on the upper fixed bracket 1431, a positioning hole 1433 is opened on the movable seat 1432, a fixed seat 1434 is fixedly installed on the bottom plate 13, a blind hole 1435 is opened in the fixed seat 1434, and a positioning column 1436 that is slidably installed in the blind hole 1435 and is engaged with the positioning hole 1433.

[0060] When the control sliding bar 142 moves along the direction of the slide rail 141, the sliding bar 142 drives the upper fixed bracket 1431 and the movable seat 1432 to move synchronously, and the movable seat 1432 moves toward the fixed seat 1434. When the side of the movable seat 1432 contacts the outer arc surface of the positioning column 1436 protruding from the side of the fixed seat 1434, the positioning column 1436 is pushed to move toward the inner side of the fixed seat 1434, and the movable seat 1432 continues to move. When the positioning hole 1433 on the movable seat 1432 moves to correspond to the positioning column 1436, the positioning column 1436 is ejected outward by the elastic thrust and is engaged in the positioning hole 1433. The engaging structure can quickly limit the moving position of the movable seat 1432 and the sliding bar 142, thereby maintaining the stability of the moving position of the refrigeration component 2 and the heating component 3.

[0061] See also Fig. 9 , Fig.10 and Fig.14 As shown, a fixing plate 1437 is fixed in the blind hole 1435 in the fixing seat 1434 , a sliding frame 1438 is slidably connected in the fixing plate 1437 , and a positioning spring 1439 is connected between the sliding frame 1438 and the fixing plate 1437 .

[0062] When the positioning column 1436 is subjected to pressure and moves toward the blind hole 1435 in the fixed seat 1434, the positioning column 1436 drives the sliding frame 1438 to move through the fixed plate 1437, and the sliding frame 1438 compresses the positioning spring 1439. When the surface of the positioning column 1436 is not subjected to pressure, the positioning spring 1439 is elastically released, pushing the sliding frame 1438 and the positioning column 1436 to move in opposite directions, and the positioning column 1436 extends out of the fixed seat 1434.

[0063] See also Figure 9-13 As shown, the locking mechanism 144 includes a fixed plate 1441 fixed on the base plate 13, a vertical groove 1442 is provided on the fixed plate 1441, an annular groove 1443 which is connected to the vertical groove 1442 is provided on the fixed plate 1441, a lower fixed bracket 1444 is fixed on the slide rail 141, a mounting seat 1445 is fixedly installed on the lower fixed bracket 1444, a rotating rod 1446 is rotatably installed in the mounting seat 1445, a volute spring 1447 is connected between the rotating rod 1446 and the mounting seat 1445, a rotating disk 1448 is coaxially fixed on the rotating rod 1446, and a clamping block 1449 is fixed on the circumferential surface of the rotating disk 1448.

[0064] When installing the refrigeration component 2 and the heating component 3, move the block 1449 downward along the vertical groove 1442 into the annular groove 1443, so that the turntable 1448 is embedded into the interior of the mounting seat 1445, and the turntable 1448 is controlled to rotate in the mounting seat 1445, so that the block 1449 slides in a circle in the annular groove 1443. At this time, the turntable 1448 and the mounting seat 1445 are in a locked state. When disassembling the refrigeration component 2 and the heating component 3, rotate the turntable 1448 so that the block 1449 rotates in the annular groove 1443 until it corresponds to the vertical groove 1442. At this time, move the turntable 1448 upward, and the refrigeration component 2 and the heating component 3 can be quickly disassembled from the base plate 13, which is convenient to operate.

[0065] See also Figure 9-13 As shown, a transmission rod 14461 is fixed on the rotating rod 1446 , and a power plate 14462 is fixedly installed on the moving seat 1432 .

[0066] The power plate 14462 moves synchronously with the moving seat 1432, and the moving seat 1432 moves in the cabinet 11 toward the ventilation panel 15. The moving seat 1432 drives the power plate 14462 to move toward the transmission rod 14461. The side of the power plate 14462 is an arc-shaped structure. The arc surface of the side of the power plate 14462 contacts the transmission rod 14461, pushing the transmission rod 14461 and the rotating rod 1446 to rotate. The rotating rod 1446 controls the card on the turntable 1448 The block 1449 rotates in a circle, so that the clamping block 1449 rotates into the vertical groove 1442, so that the turntable 1448 and the fixed plate 1441 are in an unlocked state. When the transmission rod 14461 is not subjected to thrust, the rotating rod 1446 rotates in the reverse direction due to the elastic release force of the spiral spring 1447, so that the turntable 1448 rotates in the reverse direction. The clamping block 1449 on the turntable 1448 rotates and engages into the annular groove 1443. At this time, the turntable 1448 and the fixed plate 1441 are in a locked state.

[0067] Working principle: Place items in the locker 12, and select to start the refrigeration component 2 or the heating component 3 according to the storage temperature requirements. When the refrigeration component 2 is started, the compressor 24 and the fan 5 are started to quickly reduce the temperature in the locker 12. According to the characteristics of the stored items, especially some items that are easy to air-dry, the opening and closing degrees of the air outlet 42 and the return air outlet 43 can be adjusted to adjust the air volume in and out of the locker 12. The motor is operated to control the threaded rod 62 to rotate. Under the transmission action of the threaded structure, the internal threaded column 63, the guide bracket 64 and the movable door 46 move synchronously. The movable door 46 moves in contact with the surface of the fixed door 41. The upper vent 47 and the lower vent 48 on the movable door 46 are respectively dislocated with the air outlet 42 and the return air outlet 43 on the surface of the fixed door 41. The opening and closing degrees of the air outlet 42 and the return air outlet 43 are adjusted to avoid excessive air volume causing the items in the locker 12 to dry out.

[0068] When the heating component 3 is started, the cooling mode is turned off, a proper amount of water is added to the heating pool 32, and the heater 33 is operated to heat the liquid in the heating pool 32. The hot steam acts on the bottom of the locker 12 to achieve steam heating of the locker 12. The water level sensing probe 34 can sense the change of the liquid level in the heating pool 32 to avoid dry burning of the heating pool 32. The temperature sensing probe 35 can sense the change of the water temperature in the heating pool 32 to accurately control the heating temperature.

[0069] When a failure occurs in the refrigeration component 2 or the heating component 3, the installation component 14 can quickly control the refrigeration component 2 and the heating component 3 to be removed from the cabinet 11 for maintenance, or disassembled for further maintenance, without moving the installation position of the cabinet 11, making equipment inspection and maintenance more convenient.

[0070] After removing the ventilation panel 15, the control slide bar 142 slides on the slide rail 141, and the refrigeration component 2 and the heating component 3 can be moved out of the cabinet 11. Two groups of positioning mechanisms 143 are provided on the bottom plate 13 to position the movement position of the slide bar 142. One group of positioning mechanisms 143 can limit the position where the refrigeration component 2 and the heating component 3 are moved and installed in the cabinet 11, and the other group of positioning mechanisms 143 can limit the position where the refrigeration component 2 and the heating component 3 are moved out of the cabinet 11 for external maintenance. The slide bar 142 is When moving, the moving seat 1432 is driven to move synchronously. When the moving seat 1432 moves and contacts the surface of the positioning column 1436 on the fixed seat 1434, the positioning column 1436 is squeezed to move toward the inside of the fixed seat 1434. When the positioning hole 1433 on the moving seat 1432 moves to correspond to the position of the positioning column 1436, the positioning column 1436 moves outward due to the elastic thrust of the positioning spring 1439, and the positioning column 1436 is engaged with the positioning hole 1433. The moving position of the moving seat 1432 and the sliding bar 142 is quickly limited by the engaging structure.

[0071] If the failure of the refrigeration component 2 and the heating component 3 is serious and needs to be disassembled for maintenance, move the sliding bar 142 to the outermost side, and the sliding bar 142 drives the moving seat 1432 and the power plate 14462 to move synchronously. The power plate 14462 moves and contacts with the transmission rod 14461, pushing the transmission rod 14461, the rotating rod 1446 and the turntable 1448 to rotate synchronously, and the block 1449 on the turntable 1448 rotates from the annular groove 1443 to the vertical groove 1442. At this time, the turntable 1448 and the fixed plate 1441 are installed and unlocked. The upward moving turntable 1448 can quickly disassemble and separate the refrigeration component 2 and the heating component 3 from the bottom plate 13, so as to facilitate further inspection and maintenance of the refrigeration component 2 and the heating component 3.

[0072] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
