Description

Technical Field

[0001] The present invention relates to the technical field of air source heat pumps, and in particular to a chassis structure and a shell, a heat pump outdoor unit, and an air source water heater having the same. Background Art

[0002] An air-source heat pump is an energy-saving device that uses high-level energy to transfer heat from a low-level heat source, air, to a higher-level heat source. In a heating system, it primarily utilizes the reverse Carnot principle, absorbing low-temperature heat energy from the low-level heat source air. This energy is then compressed into high-temperature heat by a compressor and transferred to a water tank for heating. The water and refrigerant exchange heat through the hydraulic module of the air-source water heater.

[0003] Air source heat pump outdoor units are usually divided into two types: integral and split. However, due to the limitations of the installation and use environment, a semi-integrated structure between the two has also been tried on the market. That is, a plate heat exchanger is added to the split air source heat pump outdoor unit. However, the outer shell of the heat pump outdoor unit needs to be re-molded, which results in a large waste of resources. Summary of the Invention

[0004] In view of this, the technical problem to be solved by the present invention is: the first aspect is to provide a chassis structure, which can enable the original shell structure to be equipped with new large components through only minor structural improvements, avoiding the need to re-mold the new shell structure and improving the resource utilization of the original shell mold structure.

[0005] In order to solve the technical problem of the first aspect mentioned above, the present invention provides a chassis structure, including a second chassis arranged side by side with the first chassis, a first middle partition card is limited and located between the first chassis and the second chassis, and the second chassis is provided with a second middle partition extending upward along a side close to the first chassis, and the second middle partition is arranged to fit and fixedly connected to the first middle partition.

[0006] Through the chassis structure described in the present invention, new large components can be added to the original shell structure through only minor structural improvements, avoiding the need to re-mold the new shell structure, and improving the resource utilization of the original shell mold structure.

[0007] Preferably, the first middle partition plate is provided with a first folded edge along a side away from the second middle partition plate, and a slot for engaging with the first chassis is provided at a lower end of the first folded edge.

[0008] By adopting the card slot clamping mode, the structural setting of the first middle partition will be simpler, and the card setting limiting effect will be reliable.

[0009] Preferably, the front end of the second middle partition is provided with a second folded edge which is in close contact with the front side of the first folded edge.

[0010] When the second folded edge is tightly attached to the front side of the first folded edge, the first folded edge can only be opened at the front end of the first middle partition. In this way, firstly, the physical division and spatial layout of the first chassis are less affected. Secondly, the fixed connection between the second middle partition and the first middle partition can also be only a fixed connection between the second folded edge and the first folded edge, which is convenient for quick positioning and assembly.

[0011] Preferably, a folding plate is provided at the lower end of the first middle partition along a side close to the second chassis, and the folding plate is at least in contact with the bottom plane of the second chassis.

[0012] By adopting the card-setting and limiting form of the folding plate, the structural setting of the first middle partition is also relatively simple, and the card-setting and limiting effect is reliable.

[0013] Preferably, the bottom planes of the first chassis and the second chassis extend downward to form a supporting frame and / or foot with a height greater than that of the folding plate.

[0014] The thickness setting of the supporting chassis and / or the base can prevent the folding plate from directly contacting the ground and support the load from the second chassis and even the first chassis, thereby effectively ensuring the stability and reliability of the integrated double chassis structure.

[0015] Preferably, a hanging groove is formed through the second middle partition plate and the first middle partition plate.

[0016] The through-opening of the hanging groove allows some parts to be suspended and installed on the second middle partition and the first middle partition as needed, and can ensure good supporting strength of the hanging installation.

[0017] Preferably, the chassis is provided with an avoidance hole for avoiding a connecting member, wherein the connecting member is used to fixedly connect the first middle partition plate and the first chassis.

[0018] The first middle partition and the first chassis are fixedly connected by connecting parts, which can further enhance the card-setting and limiting effect of the card slot, thereby making the integrated double chassis structure more reliable. The opening of the avoidance hole can effectively avoid the weakening of the connection effect enhanced by the connecting parts due to the interference of the thickness of the second chassis.

[0019] The technical problem to be solved by the present invention is also: the second aspect provides a shell, and / or the third aspect provides a heat pump outdoor unit, and / or the fourth aspect provides an air source water heater, which can enable the original shell structure to be equipped with new large components through only minor structural improvements, avoiding the need to re-mold the new shell structure, and improving the resource utilization of the original shell mold structure.

[0020] In order to solve the technical problem in the second aspect mentioned above, the present invention provides a shell having the chassis structure described in any embodiment of the first aspect.

[0021] In order to solve the technical problem in the third aspect mentioned above, the present invention provides a heat pump outdoor unit having the chassis structure described in any embodiment of the first aspect.

[0022] In order to solve the technical problem in the fourth aspect mentioned above, the present invention provides an air source water heater having the chassis structure described in any embodiment of the first aspect.

[0023] Compared with the prior art, the chassis structure and the housing, heat pump outdoor unit, and air source water heater having the same described in the present invention have the following beneficial effects:

[0024] 1) Only through minor structural improvements, the original shell structure can be equipped with new large components, avoiding the need to re-open the mold for the new shell structure and improving the resource utilization of the original shell mold structure;

[0025] 2) With only minor structural improvements, a semi-integrated heat pump outer unit casing to which a plate heat exchanger can be added can be formed on the original split-type heat pump outer unit casing, thereby avoiding the need to re-mold the semi-integrated heat pump outer unit casing and improving the resource utilization rate of the original split-type heat pump outer unit casing mold structure.

[0032] To make the above-mentioned objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments of the present invention described herein only constitute part of the embodiments of the present invention, which are only used to explain the present invention and do not constitute a limitation of the present invention. In the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0033] Example 1

[0034] like Figure 1-3 As shown, the present invention provides a chassis structure, including a second chassis 2 arranged side by side with the first chassis 1, a first middle partition 3 is limitedly located between the first chassis 1 and the second chassis 2, and the second chassis 2 is provided with a second middle partition 21 extending upward along a side close to the first chassis 1, and the second middle partition 21 is arranged to fit and fixedly connected to the first middle partition 3.

[0035] Specifically, in the prior art, the original shell structure usually only has a first chassis 1, and after the side panels and the top panel are added around the first chassis 1, the original shell structure is directly formed. Still taking the split heat pump external unit casing as an example, it only has a first chassis 1 in the prior art, and a plate heat exchanger can be added to the second chassis 2 by adding a second chassis 2. At this time, only a slight improvement is needed to the structure of the first chassis 1, that is, one of the side panels added to the first chassis 1 is changed to a first middle partition 3 that is "stuck and limited between the first chassis 1 and the second chassis 2", and then the second middle partition 21 is attached to the first middle partition 3 and fixedly connected to form the chassis structure described in the present invention, that is, an integrated double chassis structure, and then a semi-integrated heat pump external unit casing that can be equipped with a plate heat exchanger is directly formed on the basis of the integrated double chassis structure.

[0036] Therefore, through the chassis structure described in the present invention, new large components can be added to the original shell structure through only minor structural improvements, avoiding the need to re-mold the new shell structure, thereby improving the resource utilization of the original shell mold structure.

[0037] Preferably, the first middle partition plate 3 is provided with a first folded edge 31 along a side away from the second middle partition plate 21 , and a slot 311 for engaging with the first chassis 1 is provided at a lower end of the first folded edge 31 .

[0038] Specifically, the engagement of the slot 311 with the first chassis 1 provides a locking and limiting effect on the first middle partition 3 in at least the downward, leftward, and rightward directions. Of course, if the engagement is tighter, the first middle partition 3 can also be locked and limited in the upward, forward, and rearward directions. Using the locking slot 311 provides a simpler structural arrangement for the first middle partition 3 and a more reliable locking and limiting effect.

[0039] Preferably, a folding plate 32 is provided at the lower end of the first middle partition 3 along a side close to the second chassis 2 , and the folding plate 32 is at least in contact with the bottom plane of the second chassis 2 .

[0040] Specifically, the folding plate 32, when in contact with the bottom plane of the second chassis 2, forms a locking limit for the first intermediate partition 3 in the upward direction. Consequently, the first chassis 1, the second chassis 2, and the first intermediate partition 3 are assembled as a single unit in the four directions of up, down, left, and right. At this point, the first intermediate partition 3 can only move in the front-to-back direction at most. After the second intermediate partition 21 is in contact with and fixedly connected to the first intermediate partition 3, the first chassis 1, the second chassis 2, and the first intermediate partition 3 are completely assembled as a single unit, thus forming the integrated dual-chassis structure described in the present invention. The locking limit provided by the folding plate 32 also simplifies the structural configuration of the first intermediate partition 3, and the locking limit effect is reliable.

[0041] Of course, as a further preferred embodiment of the present invention, the lower end of the first intermediate partition 3 can also be provided with a folding plate 32 along the side closest to the first chassis 1, which mates with the bottom plane of the first chassis 1. In this case, the lower end of the first intermediate partition 3 will form an inverted T-shape. Alternatively, the folding plate 32 can be fixedly connected to the bottom plane of the second chassis 2 and / or the bottom plane of the first chassis 1. This can further enhance the integrated assembly effect of the integrated double chassis structure.

[0042] Preferably, the bottom planes of the first chassis 1 and the second chassis 2 are extended downward to form a supporting frame 4 and / or a bottom foot with a height greater than that of the folding plate 32 .

[0043] Specifically, there can be multiple feet, but the total number of support frames 4 can be only two, and they can be placed on the bottom planes of the first chassis 1 and the second chassis 2. The thickness of the support frames 4 and / or the feet can prevent the folding plate 32 from directly contacting the ground and support the load from the second chassis 2 and even the first chassis 1, thereby effectively ensuring the stability and reliability of the integrated dual-chassis structure.

[0044] At the same time, it should be noted that since the present invention does not require special restrictions on the size structure of the first chassis 1, the second chassis 2, and the folding plate 32, the specific position setting of the supporting frame 4 and / or the base only needs to avoid the folding plate 32 and ensure that the support of the supporting frame 4 and / or the base and the ground remains stable. In view of the fact that this is all existing technology, no further details will be given here.

[0045] Preferably, a second folded edge 211 is formed at the front end of the second middle partition 21 and is closely attached to the front side of the first folded edge 31 .

[0046] Specifically, when the second folded edge 211 is tightly attached to the front side of the first folded edge 31, the first folded edge 31 can only be opened at the front end of the first middle partition 3. In this way, firstly, the physical division and spatial layout of the first chassis 1 are less affected. Secondly, the fixed connection between the second middle partition 21 and the first middle partition 3 can also be only a fixed connection between the second folded edge 211 and the first folded edge 31, which is convenient for quick positioning and assembly.

[0047] Preferably, a hanging groove 5 is formed through the second middle partition plate 21 and the first middle partition plate 3 .

[0048] Specifically, the through-opening of the hanging groove 5 allows some components to be suspended and installed on the second middle partition 21 and the first middle partition 3 as needed, and can ensure good supporting strength for the hanging installation. For example, the plate heat exchanger can be directly attached to the right surface of the second middle partition 21 through the hanging groove 5 for suspension installation.

[0049] Preferably, the chassis 2 is provided with an escape hole 6 for escaping a connecting member, wherein the connecting member is used to fixedly connect the first middle partition plate 3 and the first chassis 1 .

[0050] Specifically, the first middle partition 3 is positioned between the first chassis 1 and the second chassis 2. When the retaining mechanism of the retaining slot 311 and the folding plate 32 is employed, the lower end of the first middle partition 3 engages both the first chassis 1 and the second chassis 2. The use of a connector to securely connect the first middle partition 3 to the first chassis 1 further enhances the retaining effect of the retaining slot 311, thereby making the integrated dual-chassis structure more secure. However, due to the thickness interference of the second chassis 2, this enhanced connection effect is weakened. The provision of the avoidance hole 6 effectively prevents this weakening of the connector's reinforcing effect.

[0051] It should also be noted that since the heights of the first chassis 1 and the second chassis 2 can be set flush or not, and the second middle partition 21 itself is also an organic part of the second chassis 2, the avoidance hole 6 can also be opened at the lower end of the second middle partition 21 as needed.

[0054] The present invention also provides a heat pump outdoor unit having the chassis structure described in Example 1.

[0055] The present invention also provides an air source water heater having the chassis structure described in Example 1.

[0056] Specifically, those skilled in the art can understand that when the shell and / or heat pump outdoor unit and / or air source water heater provided in Example 2 have the chassis structure described in Example 1, the solutions to the corresponding technical problems and the achievement of their technical effects can all be found in the description of the chassis structure in Example 1, and will not be repeated here.

[0057] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
