Description

Technical Field

[0001] This utility model relates to the field of heat exchange application technology, specifically a heat pump air conditioner suitable for kitchens. Background Technology

[0002] In the kitchens of various restaurants and canteens, the environment is usually quite hot due to the hot cooking process. Establishments with the resources typically provide separate air conditioning units to cool down staff and alleviate the effects of the heat on their physical and mental well-being. On the other hand, kitchens often require large amounts of hot water for cleaning and rinsing, so establishments with the resources usually provide separate hot water boilers. However, the purchase cost of such equipment is high, which is not conducive to cost reduction in the operation of the premises. Furthermore, the separate use of air conditioning and hot water boilers results in significant energy consumption, which is not energy-efficient or environmentally friendly. Utility Model Content

[0003] In response to the aforementioned problems in existing kitchen environments, such as equipment purchases hindering cost reduction and equipment use being detrimental to energy conservation and environmental protection, the technical solution adopted by this utility model to solve these problems is as follows: A heat pump air conditioner suitable for kitchens includes a housing and a heat exchange assembly based on the reverse Carnot cycle principle. The upper side of the housing is provided with a rotatable universal air outlet mechanism. The first heat exchanger of the heat exchange assembly for releasing heat is located on the lower side of the housing. The second heat exchanger of the heat exchange assembly for absorbing heat is located in the middle of the housing and connected to the universal air outlet mechanism. The housing is provided with a hot water storage tank near the first heat exchanger. The hot water storage tank has a water outlet pipe structure connected to the outside of the housing.

[0004] As described above, a heat pump air conditioner suitable for kitchens includes an air outlet surface a on the front side and a water outlet surface b on the rear side. The air outlet of the universal air outlet mechanism is located at the top of the air outlet surface a, and the water outlet of the water outlet pipe structure is located at the bottom of the water outlet surface b.

[0005] As described above, a heat pump air conditioner suitable for kitchens has a first ventilation surface c, a second ventilation surface d, and a third ventilation surface e located near the second heat exchanger. The first ventilation surface c and the second ventilation surface d are located between the air outlet surface a and the water outlet surface b, and the third ventilation surface e is located at the water outlet surface b.

[0006] As described above, a heat pump air conditioner suitable for kitchens has a plurality of ventilation holes provided on the first ventilation surface c, the second ventilation surface d, and the third ventilation surface e.

[0007] As described above, a heat pump air conditioner suitable for kitchens includes a compressor and an expansion valve connected between the first heat exchanger and the second heat exchanger, wherein the first heat exchanger is a condenser and the second heat exchanger is an evaporator.

[0008] As described above, in a heat pump air conditioner suitable for kitchens, the refrigerant of the heat exchange component, after being processed by the compressor, releases heat to the hot water storage tank in the first heat exchanger, thereby increasing the water temperature inside the hot water storage tank; the refrigerant of the heat exchange component, after being processed by the expansion valve, absorbs heat from the outside air in the second heat exchanger, thereby decreasing the temperature of the outside air.

[0009] As described above, a heat pump air conditioner suitable for a kitchen includes a fan for directional airflow, the fan being located above the second heat exchanger and directionally supplying air towards the air outlet of the directional airflow mechanism.

[0010] As described above, a heat pump air conditioner suitable for kitchens includes a universal air outlet mechanism comprising a hollow, through-hole air outlet rotating head and a rotating head base. The outer surface g of the air outlet rotating head is mounted on the hollow position of the inner surface h of the rotating head base by frictional rotation.

[0011] As described above, in a heat pump air conditioner suitable for kitchens, the outer surface g adopts a first spherical structure with a circular or elliptical cross-sectional shape, and the inner surface h is a second spherical structure that matches the outer surface g.

[0012] As described above, in a heat pump air conditioner suitable for kitchens, at least two of the rotating head bases are installed on the outer side of the housing in a spaced-apart arrangement aligned along a straight line. The number of air outlet rotating heads corresponding to the number of rotating head bases installed are respectively venting air in different directions. The straight line direction includes any two of the following: the vertical direction along the housing, the horizontal direction along the housing, and the front-back direction along the housing.

[0013] The beneficial effects of this utility model are as follows: This invention integrates the functions of traditional air conditioning and hot water heating equipment into one unit. It employs a heat exchange component based on the reverse Carnot cycle principle. During the heat release process in the first heat exchanger, a hot water storage tank is used to heat the water source, causing the water inside the tank to heat up and become hot water, which can be used for various purposes in the kitchen environment, such as floor cleaning and utensil washing. The second heat exchanger absorbs heat and is connected to a omnidirectional air outlet mechanism, causing the surrounding air temperature to drop, forming cool air that is then delivered to the kitchen environment via the omnidirectional air outlet mechanism. This cool air can be used for various purposes in the kitchen environment, such as cooling, floor drying, and dehumidification. With this integrated function, only one heat exchange component is needed to achieve both environmental cooling and hot water supply, reducing equipment purchase costs and improving the economic benefits of the business. The omnidirectional air outlet mechanism disperses the cool air, expanding the cooling range, making it suitable for small to medium-sized kitchen environments. Attached Figure Description

[0024] Figures 1 to 4 as well as Figure 5 This embodiment provides a heat pump air conditioner suitable for kitchens, including a housing 1 and a heat exchange assembly 2 based on the reverse Carnot cycle principle. The upper side of the housing 1 is provided with a rotatable universal air outlet mechanism 3. The first heat exchanger 21 of the heat exchange assembly 2 for releasing heat is located on the lower side of the housing 1. The second heat exchanger 22 of the heat exchange assembly 2 for absorbing heat is located in the middle of the housing 1 and is connected to the universal air outlet mechanism 3. The housing 1 is provided with a hot water storage tank 4 near the first heat exchanger 21. The hot water storage tank 4 has a water outlet pipe structure 5 that connects to the outside of the housing 1.

[0025] Specifically, in this embodiment, the outer shell 1 can be assembled from multiple bent sheet metal parts to form a fixed, integral, thin-walled outer shell structure. The heat exchange assembly 2, based on the reverse Carnot cycle principle, is installed in the inner cavity 10 of the outer shell 1. The inner cavity 10 is divided into three independent chambers by thin-walled partitions: a cold air chamber located on the upper side of the inner cavity 10, an installation chamber located in the middle of the inner cavity 10, and a hot water chamber located on the lower side of the inner cavity 10. The heat exchange assembly 2 also includes a compressor 23 and an expansion valve 24 connected between the first heat exchanger 21 and the second heat exchanger 22. The first heat exchanger 21 is a condenser, and the second heat exchanger 22 is an evaporator. Based on the reverse Carnot cycle principle, the refrigerant in heat exchange component 2, after being processed by compressor 23, releases heat to the hot water storage tank 4 through the first heat exchanger 21, raising the temperature of the water inside the tank 4. Meanwhile, the refrigerant in heat exchange component 2, after being processed by expansion valve 24, absorbs heat from the outside air through the second heat exchanger 22, lowering the outside air temperature. This process generates both cold air and hot water. The universal air outlet mechanism 3 is installed on the outer casing 1 and connects the cold air cavity to the external space. The second heat exchanger 22 is installed in the inner cavity and connects to the cold air cavity, allowing the cooled air from the second heat exchanger 22 to flow through the cold air cavity towards the universal outlet. The air outlet 3 delivers air to the external kitchen environment, achieving cooling, dehumidification, and drying effects. The first heat exchanger 21 and the hot water storage tank 4 are installed inside the hot water chamber, allowing the water heated by the heat exchanger 21 to be delivered to the external kitchen environment via the water outlet pipe structure 5 towards the water outlet 51. With the addition of external water pipes, a larger area can be cleaned, achieving flushing and cleaning effects on the kitchen environment. This embodiment integrates the functions of traditional air conditioning and traditional hot water heating equipment. The heat exchange component 2, based on the reverse Carnot cycle principle, utilizes the hot water storage tank 4 to heat the water source during the heat release process of the first heat exchanger 21. The water in the tank is heated to form hot water, which can be used for various purposes such as washing floors and cleaning utensils in the kitchen environment. The second heat exchanger 22 absorbs heat and is connected to the universal air outlet mechanism 3, which lowers the temperature of the surrounding air to form cold air, which is then sent to the kitchen environment through the universal air outlet mechanism 3. This can be used for various purposes such as cooling the kitchen environment, washing and drying floors, and dehumidifying. With the integrated functions, only one heat exchange component is needed to achieve the functions of cooling the environment and supplying hot water, reducing equipment purchase costs and improving the economic benefits of the business. Combined with the universal air outlet mechanism, the cold air is dispersed to expand the cooling range, making it suitable for small and medium-sized kitchen environments.

[0026] Furthermore, in some embodiments, the outer casing 1 includes an air outlet surface a on the front side and a water outlet surface b on the rear side. The air outlet 31 of the universal air outlet mechanism 3 is located at the top of the air outlet surface a, and the water outlet 51 of the water outlet pipe structure 5 is located at the bottom of the water outlet surface b. The air outlet surface a and the water outlet surface b are respectively arranged opposite each other to form a reasonable layout of the whole machine, which does not affect the air blowing direction during hot water cleaning and is convenient for users.

[0027] Furthermore, in some embodiments, the bottom of the housing 1 is equipped with a plurality of pulleys that facilitate pushing and pulling. The pulleys have a brake mechanism that can be opened and closed. The pulleys are respectively installed at each corner of the bottom of the housing 1. While ensuring stability, the pulleys also make it easy for the user to move the heat pump air conditioner to a suitable position, or to move the heat pump air conditioner while cleaning, which is convenient for the user.

[0028] Furthermore, in some embodiments, a temperature sensor and a temperature control element are also included installed on the heat exchange component 2. The temperature sensor collects the real-time temperature of the heat exchange component 2 or the hot water storage tank 4 and feeds it back to the temperature control element so that the user can adjust the water temperature of the hot water storage tank 4, thereby achieving the effect of adjustable and controllable water temperature. The temperature sensor can also collect the real-time temperature of the second heat exchanger 22 and feed it back to the temperature control element so that the user can adjust the air temperature of the cold air blown out, thereby achieving the effect of adjustable and controllable cold air.

[0029] Furthermore, in some embodiments, the outer casing 1 is provided with a first ventilation surface c, a second ventilation surface d, and a third ventilation surface e near the second heat exchanger 22. The first ventilation surface c and the second ventilation surface d are located between the air outlet surface a and the water outlet surface b, and the third ventilation surface e is located at the water outlet surface b. The first ventilation surface c, the second ventilation surface d, and the third ventilation surface e are each provided with a plurality of ventilation holes 11. The multiple ventilation surfaces surround the outer side of the second heat exchanger 22, making it easier for the second heat exchanger 22 to come into contact with the outside air and exchange heat, thereby improving the air circulation efficiency around the second heat exchanger 22 and improving the cold air output efficiency.

[0030] Furthermore, in some embodiments, the universal air outlet mechanism 3 includes a fan 32 for directional air delivery. The fan 32 is installed in the cold air cavity and located above the second heat exchanger 22. When in use, the fan 32 is activated to deliver air directionally toward the air outlet 31 of the universal air outlet mechanism 3, guiding the airflow from the outside of the housing 1 into the housing cavity 10 from the first ventilation surface c, the second ventilation surface d, and the third ventilation surface e. After being cooled by heat exchange in the second heat exchanger 22, the air is delivered directionally toward the air outlet 31 of the universal air outlet mechanism 3 by the fan 32.

[0031] Figures 4 to 7This embodiment provides a heat pump air conditioner suitable for kitchens. The universal air outlet mechanism 3 includes a hollow, through-hole air outlet rotating head 33 and a rotating head base 34. The outer surface g of the air outlet rotating head 33 is mounted on the hollow position of the inner surface h of the rotating head base 34 by frictional rotation. The frictional rotation method, through the control of tolerances during production, eliminates the need for hinged accessories between the air outlet rotating head 33 and the rotating head base 34, reducing accessory costs and simplifying assembly steps. Furthermore, the frictional rotation method allows users to directly and manually adjust the angle and position of the air outlet direction, simplifying the way users adjust the air outlet direction.

[0032] Furthermore, in some embodiments, the outer surface g adopts a first spherical structure with a circular or elliptical cross-sectional shape, and the inner surface h is a second spherical structure that matches the outer surface g. The spherical structure facilitates the formation of a rotatable and adjustable universal air outlet mechanism 3. There is no need for hinged accessories to install between the air outlet rotating head 33 and the rotating head base 34, which reduces accessory costs, simplifies assembly steps, and the frictional rotation method allows users to directly and manually adjust the angle and position of the air outlet direction, simplifying the way users adjust the air outlet direction.

[0033] Furthermore, in some embodiments, at least two rotating head bases 34 are installed on the outer side of the housing 1 in a spaced-apart arrangement aligned along a straight line. The number of air outlet rotating heads 33 installed on the rotating head bases 34 are respectively venting air in different directions. The straight direction includes any two of the following: the vertical direction i along the housing 1, the horizontal direction j along the housing 1, and the front-back direction k along the housing 1. Preferably, four rotating head bases 34 are arranged in a rectangular array along the vertical direction i and the horizontal direction j of the housing 1. Each of the four rotating head bases 34 is equipped with a rotatable air outlet rotating head 33. During use, the user can adjust each air outlet rotating head 33 to achieve the effect of venting air in different directions, or all air outlet rotating heads 33 can vent air towards the ground together to concentrate the air force to dry and dehumidify the ground, which is convenient for the user.

[0034] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
